1 to 4 , the renal endoscope simulator system 1 according to an embodiment may practice kidney stone removal surgery through a ureteroscope.

The renal endoscopy simulator system 1 according to an embodiment includes a base 11, an artificial bladder 12, an artificial ureter 13, a kidney model 14, a water supply unit 15, a control unit 16, and an artificial kidney module. (2) may be included.

The base 11 may support the artificial bladder 12 , the artificial ureter 13 , the kidney model 14 , and the artificial kidney module 2 to be practiced through the ureteroscope.

For example, the base 11 drains water to the lower side of the artificial bladder 12 so that water supplied from the artificial kidney module 2 and flowing to the artificial bladder 12 can be circulated to the water supply unit 15 . It may include a drainage unit 111 that can be. For example, the drain unit 111 may be a hole formed in the base 11 to communicate with the water supply unit 15 , or a housing that temporarily accommodates water such as a water tank and communicates with the water supply unit 15 . .

The artificial bladder 12 may be a member in the form of a bladder having an internal space simulating the shape of a human bladder. The artificial bladder 12 may be connected to the artificial ureter 13 on one side, and may be exposed to the outside on the other side of the opposite direction and an opening through which a ureteroscope can be introduced may be formed.

The water supplied through the artificial kidney module 2 may be connected to the artificial ureter 13 and delivered to the artificial bladder 12, and the water discharged through the opening of the artificial bladder 12 is located on the lower side according to gravity. It may be discharged to the drain unit 111 .

As another example, it should be noted that in addition to the opening of the artificial bladder 12, a long tube-shaped member simulating the urethra of the human body may be additionally installed.

For example, the artificial bladder 12 may be formed of a polymer material having permeability so that the movement of the insertion tube of the ureteroscope passing through the interior can be observed from the outside.

On the other hand, it should be noted that the artificial bladder 12 is not necessarily provided, and in this case, the ureteroscope can be directly inserted through the discharge side of the artificial ureter 13 .

The artificial ureter 13 may be a tube-shaped member that mimics the ureter of a human body. The artificial ureter 13 may have a pair of configurations connected from the artificial bladder 12 .

For example, among the pair of artificial ureters 13, one ureter 13 may be referred to as a first ureter 13a, and the other ureter 13 may be referred to as a second ureter 13b. have. Here, the distinction between the first ureter 13a and the second ureter 13b is only for mutual distinction according to the structure of a pair of ureters that are actually connected to each of the pair of kidneys, and contains a specific directionality. make it clear that it is not

Also, as shown in FIG. 1 , the first ureter 13a is connected to the kidney model 14 and the second ureter 13b is shown to be connected to the artificial kidney module 2 , but this is in one example. It should be noted that only the artificial ureters (13a, 13b) may be connected to any configuration.

The kidney model 14 is a member simulating the height of the human body, and may include an internal channel 141 communicating with the artificial ureter 13 therein. The inner channel 141 may be formed as a passage branched from the artificial ureter 13 into a plurality so that the endoscope inserted through the artificial ureter 13 can be accessed. The inner channel 141 may have a shape simulating the structure of the renal pelvis and the renal calyces connected therefrom.

For example, the artificial bladder 12, the kidney model 14, and the artificial ureter 13 may be formed of a polymer material having permeability so that the movement of the insertion tube of the ureteroscope can be observed from the outside. For example, the kidney model 14 is formed of a transparent or translucent material, so that the point at which the endoscope is inserted can be visually confirmed even from the outside. Therefore, in the case of an unskilled person unfamiliar with endoscopic manipulation, by first training to insert the endoscope through the first ureter 13a, the endoscopic operation can be more easily accustomed to. Meanwhile, the artificial bladder 12 , the kidney model 14 , and the artificial ureter 13 may have the same color as the actual human bladder, kidney, and ureter colors, respectively.

The water supply unit 15 may supply water to the artificial kidney module 2 to simulate the movement of stones flowing in the actual kidney. In addition, since the artificial kidney module 2 can be cooled by using the water supplied from the water supply unit 15 without additional cooling means, it is possible to create a laser use environment that can be used for simulating stone crushing.

For example, the water supply unit 15 may implement the movement of the stone (S) accommodated in the artificial kidney module (2) by supplying water to the artificial kidney module (2) through a supply pump or the like. Water used to move the stone (S) may be discharged through the artificial ureter 13 into which the endoscope is inserted, without a separate discharge means. Through this structure, while continuously supplying water from the water supply unit 15 to the artificial kidney module 2, it is possible to implement the movement of the stone (S). For example, water discharged through the drain unit 111 may be supplied back to the water supply unit 15 . According to this structure, without the need to additionally supply water, by recovering the water discharged from the artificial bladder 12 back to the water supply unit 15, through the circulation process, it is possible to implement the movement of the stone (S). For example, the water supply unit 15 may include a pump structure capable of accommodating water and supplying it to the outside.

For example, the water supply unit 15 may include a plurality of supply lines 151 that are connected to a plurality of new distribution channels 234 of the multi-channel unit 23 and supply water to each new distribution channel 234 . have. For example, each of the plurality of supply lines 151 may be provided with a valve capable of opening and closing the corresponding supply line 151 . According to such a configuration, water can be supplied only to some of the kidney channels 234 in which the stones S are located among the plurality of kidney channels 234 . The above-described valve may be, for example, a valve capable of adjusting the opening degree. According to such a valve, it is possible to individually adjust the degree of movement of the stone (S) for each of the plurality of renal distribution channels (234).

On the other hand, unlike shown, the supply line 151 is connected to the inner channel 141 of the kidney model 14, it is put out that water may be supplied to the inner channel (141).

The control unit 16 may control the water supply unit 15 to adjust the flow rate and flow rate of water supplied to the artificial expansion module 2 .

For example, the controller 16 may individually control the flow of water flowing in each of the plurality of supply lines 151 , and as a result, the flow of water flowing into the plurality of new distribution channels 234 may be individually controlled. . For example, the control unit 16 can control the opening degree of each valve described above.

The artificial kidney module 2 creates an environment in which stones are formed in the structure of the actual kidney, so that an operation for removing stones through an actual endoscopic operation can be practiced. The artificial kidney module 2 may communicate with the artificial ureter 13 which is connected from the artificial bladder 12 .

Meanwhile, referring to FIGS. 1 to 4 , the artificial kidney module 2 is illustrated as having a structure and a direction corresponding to a left kidney among a pair of kidneys in the human body, but this is only an example, and vice versa It should be noted that constructions with structures and directions corresponding to symmetrical elongation of directions are also possible.

The artificial kidney module 2 may include a case 21 , a branch portion 22 , a multi-channel portion 23 , and a stone (S).

The case 21 may be a housing-type member accommodating the branch portion 22 and the multi-channel portion 23 therein. For example, the case 21 has an internal space 211 , a connection part 213 through which the artificial ureter 13 is introduced into the internal space 211 , and a cover part 214 capable of shielding the internal space 211 from the outside. ) and a plurality of supply ports 215 into which a plurality of supply lines 151 are introduced into the inner space 211 may be included.

The branch part 22 and the multi-channel part 23 may be accommodated in the inner space 211 . The internal space 211 may support the branching part 22 and the multi-channel part 23 in a state in which they are aligned with each other. For example, the inner space 211 may have a semi-circular column shape corresponding to a shape in which the branch part 22 and the multi-channel part 23 are combined.

For example, as the shape of the inner wall of the inner space 211 has a structure that matches the shape formed by the outer surface formed by the branch portion 22 and the multi-channel portion 23, the branch portion 22 and multiple The channel part 23 may be fixedly supported by being fitted to the inner wall of the inner space 211 , while the branch part 22 and the multi-channel part 23 may be connected to each other to be in close contact with each other.

3 and 4 , the cross-section of the inner space 211 may include a circular shape including an arc. However, this is only an example, and the shape of the branch portion 22 and the multi-channel portion 23 including the internal space 211 is not limited thereto, and it is easily understood from those skilled in the art that it can be implemented with various shapes. it could be

The connecting portion 213 is a port communicating with the inner space 211 through the inner wall of the case 21 from the outside, and the end of the artificial ureter 13 may be connected. For example, the connection part 213 may be connected to the introduction pipe 221 of the branch part 22 installed in the inner space 211 .

The cover part 214 may be detachably separated to shield the internal space 211 from the outside. The cover part 214 may prevent the water supplied to the inner space 211 from flowing out to the outside of the case 21 . Since the sealing member is provided between the cover part 214 and the inner space 211 , the water supplied to the inner space 211 may be discharged through the artificial ureter 13 without leaking to the outside.

For example, the cover part 214 may serve to shield the internal space 211 while pressing the multi-channel part 23 accommodated in the internal space 211 to firmly fix it.

For example, the cover part 214 may be formed of a member with a part of which is permeable so that, for example, the cover part 214 can observe the shielded internal space 211 from the outside.

As shown in Figure 4, in order to insert or remove the stone (S) into the multi-channel section 23, after separating the cover section 214 from the internal space 211, the multi-channel section 23 inside It can be taken out of the space 211 .

A plurality of supply ports 215 may be installed in a portion of the internal space 211 where the multi-channel unit 23 is installed. Each of the plurality of supply ports 215 may be connected to one side of each of the plurality of new distribution channels 234 formed inside the multi-channel unit 23 . The multi-channel portion 23 may have a columnar shape having an arc-shaped cross-section, and thus, a plurality of supply ports 215 may also be formed in an arc-shaped region. In other words, the plurality of supply ports 215 may be radially arranged around the branch portion 22 . For example, the plurality of supply ports 215 may be connected from the lower side of the inner space 211 along the direction of gravity.

For example, when the multi-channel portion 23 is coupled to a position where it is accurately coupled to the branch portion 22 in the internal space 211 , a plurality of supply ports 215 is provided on one side of each of the plurality of new distribution channels 234 . can be connected to precisely engage with the

In other words, the multi-channel unit 23 includes a passage for interconnecting the renal distribution channel 234 and the supply port 215 , and the water supplied to the supply port 215 is transmitted through the above-described passage through the renal distribution channel 234 . ) can be introduced.

According to the above structure, the water supplied from the water supply unit 15 to the artificial kidney module 2 is individually supplied to each of the plurality of renal channels 234 so that the stones flow in the renal calyces of the actual kidney. can imitate

The branching part 22 is installed in a portion connected to the connection part 213 of the internal space 211 , and may form an internal path communicating from the artificial ureter 13 to the multi-channel part 23 . For example, the introduction tube 221 of the branch 22 may communicate with the artificial ureter 13 . The branch portion 22 may have a columnar shape having a cross section of a semicircle or a sector shape.

For example, the branch 22 includes an introduction tube 221 that communicates with the artificial ureter 13 through the connecting portion 213, and a branch pipe that branches from the introduction tube 221 and communicates with the internal space 211 ( 222 , and a coupling end 223 connected to the multi-channel part 23 and exposed to the branch pipe 222 .

The introduction tube 221 is a portion communicating with the artificial ureter 13 and may have a tube shape simulating the renal pelvis portion of the kidney that is actually connected to the ureter.

The branch pipe 222 may have a pipe shape that is connected from the introduction pipe 221 and is branched and opened in plurality toward the coupling end 223 . For example, the branch pipe may have a tubular shape simulating a portion branching into two or three major calyx in the renal pelvis of the actual kidney.

The coupling end 223 is a portion in which an opening through which the branch pipe 222 is exposed is formed, and may be coupled to the separation end 231 of the multi-channel part 23 .

When the coupling end 223 and the separation end 231 are coupled to each other, the opening of the branch pipe 222 exposed at the coupling end 223 may be communicated with the renal inlet 233 exposed at the separation end 231 . have.

When the branch portion 22 and the multi-channel portion 23 are coupled, the coupling end 223 and the separation end 231 may have a structure in which their respective contact surfaces are matched to each other so that they can be in close contact with each other at the correct coupling position. have. For example, as shown in FIGS. 3 and 4 , the engaging end 223 may have a protruding shape along an arc shape, and thus the separating end 231 may be inwardly aligned along the same arc shape. It may have a recessed shape.

The multi-channel part 23 is installed in a portion connected to the branch part 22 of the internal space 211 . The multi-channel part 23 may form an internal path communicating from the internal passage of the branch part 22 , and may be connected to the branch pipe 222 on one side and a plurality of supply ports 215 on the other side. The multi-channel part 23 may be detachably installed in the inner space 211 .

For example, the multi-channel portion 23 includes a separation end 231 coupled to the coupling end 223 of the branch 22, a separation outer surface 232 in close contact with the inner wall of the inner space 211, It may include a renal glia inlet 233 which is recessed inwardly from the separation end 231 and a plurality of renal glia channels 234 that are connected from the renal glia inlet 233 and are branched into a plurality of paths.

The separation end 231 is a portion where the inlet 233 is exposed to the outside, and may be coupled to the coupling end 223 of the branch 22 .

As described above, the separating end 231 may have a recessed shape corresponding to the protruding shape of the coupling end 223 . For example, the separation end 231 may form an arc-shaped contact surface recessed inward.

Depending on the structure of the coupling end 223 and the separating end 231 having shapes corresponding to each other, when the multi-channel portion 23 is coupled to the branch portion 22, it can be guided to have an accurate coupling position with each other, and also Each branch pipe 222 and the renal grail inlet 233 can be aligned to engage accurately. In addition, the coupling end 223 and the separating end 231 are in surface contact with each other in close contact with each other except for the branch pipe 222 and the new inlet 233, preventing the water flowing from the inside from leaking out. can do.

On the other hand, it is pointed out that the shape of the contact surface of each of the coupling end 223 and the separation end 231 may include any other shape having a structure that can be molded and closely adhered to each other.

The separation outer surface 232 may be an outer portion that is in close contact with the inner wall of the inner space 211 . The separation outer surface 232 may have an outer cross-sectional shape that matches the cross-sectional shape of the inner wall of the inner space 211 so as to be in close contact with the inner wall of the inner space 211 .

3 and 4, when a portion of the inner wall of the inner space 211 has a cylindrical shape, the separation outer surface 232 also has an outer structure of a cylindrical shape, so that the separation outer surface 232 is the inner space It may be arranged to be in close contact along the inner wall of the 211 .

According to the above structure, the multi-channel part 23 can be arranged to have an accurate coupling position in the internal space 211 , and through this, the new-bae inlet 233 of the multi-channel part 23 is connected to the branch part 22 . At the same time accurately engaging and communicating with the branch pipe 222 , the ends of the plurality of exhalation channels 234 of the multi-channel part 23 may also be aligned to communicate while being accurately engaged with each of the plurality of supply ports 215 .

As a result, when the multi-channel portion 23 is installed in the inner space 211, it is stably and fixedly supported from both sides of the separation end 231 and the separation outer surface 232, so that the multi-channel portion 23 is formed in the interior space. It can be prevented from being separated from the correct coupling position in the 211 .

In addition, according to the outer circumferential structure, a structure in which the renal cerebellum inlet 233 connected to the branch pipe 222 on one side and at least one or more renal diaphragm channels 234 on the other side is exposed to the outside may be formed. The renal inlet 233 may include an opening portion exposed to the separating end 231 . Sinbae entrance 233 may have the shape of a tube simulating a portion that is branched and connected to a plurality of minor calyx from the major calyx of the actual kidney.

For example, the same number of inlets 233 as the number of branch pipes 222 may be formed at points spaced apart from each other along the separation end 231 .

The plurality of renal channels 234 may be passages that are branched and connected to have at least one path from the renal inlet 233, and are connected to each of the plurality of supply ports 215 at the end of each passage to supply water. can receive

The plurality of renal glia channels 234 may have a tube shape simulating the structure of a minor calyx that is branched and connected in plurality from the major calyx of the actual kidney.

As a result, the shape of the passage branching from the introductory tube 221 through the branch pipe 222 and the renal inlet 233 to the plurality of renal channels 234 and communicating is, from the renal pelvis of the actual kidney to the large intestine. It may have a three-dimensional passage shape that branches and communicates through (major calyx) to minor calyx.

In addition, in the artificial kidney module 2, even if the heights of the plurality of renal and glia channels 234 have different three-dimensional structures, in a state in which the multi-channel part 23 is separated, the renal glia inlet 233 exposed to the outside. It is possible to insert the stones (S) into each of the plurality of renal channels 234 through. Therefore, compared to a general artificial kidney module that places the stone (S) on the same plane in two dimensions, it has the advantage of being able to perform much more realistic training.

When the multi-channel portion 23 in the inner space 211 as shown in Figure 3 is coupled at the correct coupling position with the branch portion 22, each new distribution channel 234 is coupled while being engaged with each of the plurality of supply ports 215 Thus, water can be individually supplied to each of the plurality of new distribution channels 234 .

For example, the renal grail channel 234 may include a structure that slopes downward along the direction of gravity as it goes from the renal glia inlet 233 to the supply port 215 .

According to the above structure, when the stone (S) is placed in the renal glia channel 234 or the renal glia inlet 233 portion, the stone (S) receives a force to move toward the end of the renal glia channel 234 by gravity at the same time. , is supplied through each supply port 215 and receives a force in a direction away from the end of the renal glia channel 234 by the back-flowing water, as a result, the stone (S) is the renal glia inlet 233 or renal glia channel It can be created to have the movement of the stone in the kidney by making it have an irregularly oscillating motion in the state moored at (234).

For example, the portion in which the plurality of supply ports 215 are installed in the inner space 211 may be installed at points radially spaced apart from each other based on the arc shape of the separation end 231 .

In other words, the plurality of supply ports 215 may have different radial angles each formed based on the arc shape.

Accordingly, the plurality of new and distributed channels 234 of the multi-channel unit 23 may also be radially distributed based on a corresponding arc shape within a structurally possible orientation range.

For example, the plurality of supply ports 215 may protrude in a direction perpendicular to a radial plane with respect to the arc shape of the separation end 231 and be connected to each of the plurality of renal distribution channels 234 .

In this case, the vertical direction may be the opposite direction to the direction of gravity, through which the flow of water supplied to the renal grail channel 234 and flowing backward to the upper side is advantageous to form a turbulence to effectively moor the stone (S). can

For example, through the inlet pipe 221 and the branch pipe 222 of the branch 22, the channel branched to the renal inlet 233 and the plurality of renal distribution channels 234 of the multi-channel unit 23 are extended. The structure may form a three-dimensional passage structure that is bent and branched along a three-dimensional direction, similar to the internal structure of an actual kidney.

For example, the branch portion 22 and the multi-channel portion 23 may have the same color as the actual kidney. For example, the branch portion 22 and the multi-channel portion 23 may be formed of a polymer material having permeability so that the movement of the insertion tube of the ureteroscope passing through the inside can be observed from the outside. On the other hand, unlike this, in order to provide an environment similar to the actual endoscope insertion environment, it is pointed out that it may be formed of an opaque or translucent red material.
