Example

1-4 , the present embodiment provides a vaginal occlusion device, including a occlusion balloon 100, which is used to occlude the vagina 600. The occlusion balloon 100 has at least one operating channel 200 disposed therein. The operating channel 200 is independent of the inner cavity of the occlusion balloon 100. One end of the operating channel 200 is connected to a surgical nozzle 500, and a plurality of one-way valves 300 are disposed therein.

In this embodiment, the vagina 600 can be blocked by the blocking airbag 100, and a surgical nozzle 500 is provided at the entrance of the operating channel 200 to facilitate the entry of surgical instruments. At the same time, a plurality of one-way valves 300 are provided inside the surgical nozzle 500. After the vagina 600 is blocked by the blocking airbag 100, when the corresponding surgical instrument is inserted into the operating channel 200, the surgical instrument can pass through the one-way valve 300 and then be inserted into the abdominal cavity. When the surgical instrument is rotated at any angle or direction, the one-way valve 300 can effectively fit the surgical instrument, thereby ensuring the airtightness of the pneumoperitoneum environment during the use of the surgical instrument, reducing the risk of air leakage, ensuring the long-term effectiveness of the pneumoperitoneum environment, meeting the use requirements, and having high practicality.

It should be noted that the blocking balloon 100 and the one-way valve 300 are both made of medical materials, such as medical rubber materials, including natural rubber and various synthetic rubbers, such as silicone rubber or butyl rubber, which have certain elasticity and good sealing effect.

As an optional embodiment, the blocking airbag 100 includes an inner bag layer 110, the outer wall of the inner bag layer 110 is covered with an outer bag layer 120, and the outer surface of the outer bag layer 120 is a friction surface.

In this embodiment, the blocking airbag 100 is designed to have a double-layer structure of an inner airbag layer 110 and an outer airbag layer 120, so as to prevent a single-layer airbag from being accidentally damaged during surgery and causing the airbag to be unable to be used normally, thereby affecting the operation. Damage to either the inner airbag layer 110 or the outer airbag layer 120 will not affect the integrity of the other layer, thereby ensuring that an airbag layer can remain inflated when it is accidentally damaged during surgery, thereby ensuring the normal operation of the operation and improving safety. The outer surface of the outer airbag layer 120 is a friction surface, which can increase the friction with the inner wall of the vagina 600, thereby improving the anti-slip effect and improving the stability of the operation.

As an optional implementation, the blocking balloon 100 is ellipsoidal, and the long diameter direction of the blocking balloon 100 is perpendicular to the length direction of the operating channel 200 .

In the present embodiment, the blocking airbag 100 is designed to be ellipsoidal in shape, so as to reduce the space occupied in the vagina 600. Moreover, when the blocking airbag 100 blocks the vagina 600, the length direction of the operating channel 200 is along the direction of the vagina 600. Therefore, the long diameter direction of the ellipsoidal blocking airbag 100 and the length direction of the operating channel 200 are designed to be perpendicular to each other. That is, the long diameter ends of the blocking airbag 100 can be used to press against the inner wall of the vagina 600, while the short diameter direction of the blocking airbag 100 is used to pass surgical instruments. This not only reduces the space occupied, but also reduces the length of the surgical instruments in the operating channel 200, that is, reduces the restrictions on the surgical instruments, thereby improving the operational flexibility of the surgical instruments.

As an optional embodiment, one end of the operating channel 200 away from the surgical tube opening 500 is a trumpet-shaped opening 210 .

In this embodiment, the outlet end of the operating channel 200 is designed as a trumpet-shaped opening 210, which facilitates the passage of surgical instruments and increases the range of motion of the surgical instruments, thereby further improving the rotation flexibility of the surgical instruments.

As an optional embodiment, it also includes an inflation component 400, which is used to inflate the blocking airbag 100. When it needs to be used, the blocking airbag 100 and the inflation component 400 are assembled, and then the blocking airbag 100 is pre-inflated by the inflation component 400. After the blocking airbag 100 is inflated to a certain size, the blocking airbag 100 is placed at the corresponding position of the vagina 600, and the blocking airbag 100 is continued to be inflated by the inflation component 400 until the blocking airbag 100 expands to a suitable size to block the vagina 600. It can adapt to vaginas 600 of different sizes and has universality.

As an optional embodiment, the inflation component 400 includes a connecting tube 410 connected to the blocking airbag 100, a switch valve 420 is provided on the connecting tube 410, a connector 430 is provided at the end of the connecting tube 410, and the connector 430 is detachably connected to an inflation mechanism 440.

In the present embodiment, when inflation is required, the pumping mechanism 440 is connected to the connector 430, and the air can be pumped into the blocking airbag 100 through the connecting tube 410 by continuously pumping air through the pumping mechanism 440. When the blocking airbag 100 expands to a certain extent, the switch valve 420 is closed to avoid air leakage. Since the pumping mechanism 440 and the connector 430 are detachable structures, the pumping mechanism 440 can be removed after inflation to avoid the pumping mechanism 440 occupying position and affecting the surgical operation, so that the next step can be performed. The operation is convenient and quick, and the practicability is high.

It should be noted that the connecting tube 410 and the blocking airbag 100 can also be designed as a detachable structure. A one-way air hole can be provided on the blocking airbag 100, and an air needle that cooperates with the one-way air hole is connected to one end of the connecting tube 410. When it is needed, the air needle is inserted into the one-way air hole to perform the next inflation operation. After the inflation is completed, the air needle can be pulled out of the one-way air hole, so that the connecting tube 410 can also be taken out. Finally, only the blocking airbag 100 is left in the vagina 600, further increasing the operating space and reducing the impact of the connecting tube 410 on surgical instruments. The one-way air hole here is similar to the air hole on a basketball. There is a rubber pad in the eye of the ball. When an air needle is inserted to inflate, the rubber pad will be opened by the huge pressure of the air needle. When the air needle is pulled out, the air in the ball will give the rubber pad an outward force, causing the rubber pad to return to a tightly closed state. Therefore, when the air needle is taken out, the one-way air hole will automatically close, and the blocking airbag 100 will not leak, meeting the use requirements.

As an optional embodiment, the inflation mechanism 440 includes an air pump 441, one end of which is connected to an interface tube 442 that cooperates with the joint 430, a piston block 443 is slidably arranged inside the air pump 441, and the end of the piston block 443 away from the interface tube 442 is connected to a push rod 444 that movably extends out of the other end of the air pump 441.

In this embodiment, when operating the inflation mechanism 440, first pull the push rod 444 to pull the piston block 443 away from the farthest end of the interface tube 442. At this time, the air pump 441 is full of air. Insert the interface tube 442 into the joint 430, and then push the push rod 444 inward to make the piston block 443 push the air in the air pump 441 into the connecting tube 410. Finally, the air enters the sealing airbag 100 to achieve inflation. After the inflation is completed, remove the interface tube 442 from the joint 430. The operation is convenient and quick.

It should be noted that the inflation mechanism 440 here is similar in structure to a medical syringe, except that it has one less needle. Therefore, an existing medical syringe can be directly used without the needle, and there is no need to manufacture it separately, thus reducing costs. When all the air in the air pump 441 is pushed in, the expansion degree of the blocking air bag 100 is still insufficient. At this time, the switch valve 420 can be closed to prevent air leakage, and then the air pump 441 is removed, and the push rod 444 pulls the piston block 443 away from the farthest end of the interface tube 442, and the above-mentioned inflation operation is repeated to ensure the expansion degree of the blocking air bag 100.

As another optional embodiment, the inflating mechanism 440 includes a push-on air valve 445, which is connected to an air pipe 446, which is connected to a plug 447 that matches the connector 430. The push-on air valve 445 is provided with an air nozzle 448, which is connected to a connecting belt 449, which is connected to a plug 4410 for blocking the air nozzle 448.

In this embodiment, during operation, the plug 447 is inserted into the connector 430, and the pressing valve 445 is continuously pressed manually. At this time, the air nozzle 448 on the pressing valve 445 is open, thereby pressing the external gas into the blocking airbag 100. After the blocking airbag 100 is inflated to a certain degree, the air nozzle 448 on the pressing valve 445 is first blocked by the plug 4410, and then the switch valve 420 is closed to prevent air leakage. Finally, the plug 447 can be pulled out to realize the inflation operation, which is convenient and quick to operate.

It should be noted that the plug 4410 is connected by a connecting belt 449, which can prevent small-volume components such as the plug 4410 from being lost.

As an optional embodiment, the connecting tube 410 is a telescopic bellows with a telescopic function, so that the connecting tube 410 can be stretched outside the vagina 600 during inflation, which facilitates the assembly and disassembly of the connector 430 and the inflation mechanism 440; when not in use, the connecting tube 410 can be shortened for easy storage and to avoid entanglement with other instruments.

The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
