Description

Control handle, valve suture device and valve suture system

Technical Field

Background

The tricuspid valve is a one-way valve between the right atrium and the right ventricle, and the anatomy structure of the tricuspid valve comprises an annulus, valve leaflets, chordae tendinae and papillary muscles, the valve leaflets consist of an anterior valve, a posterior valve and a septal valve, the annulus is the attachment edges of the three valve leaflets, and the free edges of the valve leaflets are connected with the papillary muscles through the chordae tendinae. The normal tricuspid valve can ensure that blood circulation flows from the right atrium to the right ventricle, and when the right ventricle contracts to squeeze the blood in the chamber, the tricuspid valve is closed, the blood cannot flow back to the right atrium, so that the blood in the right ventricle is sent to the pulmonary artery through the pulmonary valve. Tricuspid valve regurgitation is the regurgitation of right ventricular blood into the right atrium during systole caused by tricuspid insufficiency, and then into the upper and lower vena cava, which causes the volume of the right atrium to be enlarged, the pressure to be increased, and the load of the right ventricle to be increased, thus easily causing heart failure.

The traditional treatment for tricuspid valve regurgitation is valve repair or replacement by surgical procedures, which can alleviate the symptoms and prolong the life of the patient. However, surgical procedures have the disadvantages of high trauma, slow recovery, high risk, etc. In recent years, treatment of tricuspid regurgitation by a minimally invasive intervention mode gradually becomes a research hotspot, but the handle of the existing minimally invasive intervention valve repair instrument usually has the defects that an operator needs to hold the handle, the manipulating pieces are dispersed in different positions of the handle, such as the front side and the side surface, and the operation is inconvenient, and especially when the distal end of the instrument needs to be rotated to enable the distal end of the instrument to clamp different valve leaflets and implant sutures into the corresponding valve leaflets, the distal end of the instrument is often rotated by the operator and the whole instrument, and after the distal end is rotated to the proper position, the handle needs to be kept in the current state (part of the manipulating pieces may be rotated to the side surface or the back surface of the handle) and then the manipulating pieces are operated, so that the operation is more inconvenient.

The process of assembling the pin locking/unlocking control module 217 is to place the pin control module 217 in the first housing 211, so that the pushing member 2174 and the pin locking/unlocking operation member 2170 pass through the second through hole 2115 to expose the front surface 2110; nuts 2177 are then screwed on the front and back sides of the second through holes 2115, respectively, to define the limit positions to which the pushing member 2174 and the pin lock operation member 2170 can move by a nut 2177, respectively.

The process of assembling the probe movement control module 218 includes placing the fixing frame 2185 of the probe movement control module 218 in the first housing 211, so that the sliding member 2186 is slidably assembled on the fixing frame 2185, and the two second connecting members 2182 are fixed to the sliding member 2186 at intervals; the fixed frame 2185 is then fixed to the first housing 211, so that the probe moving operation element 2180 penetrates through the guide slot 2116, and the locking element 2187 is locked with the housing 210.

The process of assembling the pin module 25 and other components of the manipulating handle 21 is: sleeving the pin handle seat 253 on the distal end of the pin handle 251, wherein the positioning ring groove 2512 is exposed out of the distal end of the pin handle seat 253; sleeving the locking piece 2171 on the positioning ring groove 2512 of the pin inserting handle 251 to enable the two locking rods 2173 to face the positioning ring groove 2512; sleeving a contact pin handle 251 on the near end of the rotating mandrel 2150, and fixing the near ends of the two contact pins 250 on the contact pin handle 251 respectively; placing the rotating mandrel module 215 in the first housing 211, so that the inner walls of the openings 21612 of the first connecting pieces 21611 are rotatably received in the first ring grooves 21561, the inner walls of the openings 21820 of the two second connecting pieces 2182 are respectively rotatably received in the second ring grooves 21571 of the two second ring grooves 2157, the valve housing 2253 of the tee assembly 225 is connected in the first housing 211, and the pushing member 2174 abuts against the abutting rod 2172 of the locking member 2171; then, the second housing 213 is fastened to the first housing 211, the first distal wall 2111 of the first housing 211 and the second distal wall 2131 of the second housing 213 are respectively and rotatably inserted into the rotation guide groove 2155 of the rotation operation member 2151, and the first proximal wall 2113 of the first housing 211 and the second proximal wall 2133 of the second housing 213 are respectively and rotatably inserted into the rotation guide groove 2531 of the pin handle seat 253.

Referring to fig. 11 and 12, when the chuck opening and closing control module 216 is used to control the chuck module 23, the opening and closing of the distal chuck 235 is controlled by the chuck opening and closing control module 216 cooperating with the chuck module 23. The first transmission member 2167 is driven to rotate by rotating the chuck opening and closing operation member 2160, the first transmission member 2167 drives the lead screw 21684 to rotate through the second bevel gear 21682, the rotation of the lead screw 21684 drives the first connecting piece 21611 to move axially, and the first connecting piece 21611 drives the first collar 2156 and the chuck push tube 230 connected to the first collar 2156 to move axially, so that the distal chuck 235 is far away from or close to the proximal chuck 231, thereby opening or closing the space between the distal chuck 235 and the proximal chuck 231.

Specifically, as shown in fig. 11, the chuck opening and closing operation piece 2160 is rotated clockwise to drive the first transmission piece 2167 to rotate clockwise; since the first bevel gear 21675 is engaged with the second bevel gear 21682, the rotation of the first transmission member 2167 drives the screw rod 21684 to rotate, so as to drive the first connection piece 21611 to move axially and proximally, the first connection piece 21611 drives the first collar 2156 to move axially and proximally along the rotating spindle 2150, the first collar 2156 drives the collet pushing tube 230 to move axially and proximally, and the collet pushing tube 230 drives the distal collet 235 to move axially and proximally towards the collet 231, so that the collet module 23 is in a state of closing or clamping the valve. As shown in fig. 12, the first transmission member 2167 is driven to rotate counterclockwise by rotating the chuck opening/closing operation member 2160 counterclockwise, and since the first bevel gear 21675 engages with the second bevel gear 21682, the rotation of the first transmission member 2167 drives the screw rod 21684 to rotate, so as to drive the first connection piece 21611 to move axially and distally, the first connection piece 21611 drives the first collar 2156 and the chuck push tube 230 to move axially and distally, and the chuck push tube 230 drives the distal chuck 235 to move axially away from the proximal chuck 231, so as to open the chuck module 23. During the above movement of the collet pushing tube 230, the distance of the axial movement of the collet pushing tube 230 can be obtained by observing the scale value of the first window 2117, so as to prompt the operator what state the collet module 23 is in. When the distal collet 235 has moved to the fully open state or the fully closed state of the collet module 23, if the collet module 23 may be damaged by further moving the collet pushing tube 230, to prevent the collet module 23 from being damaged, the knob 21601 is rotated relative to the driving connector 21603 when the knob 21601 is further rotated in the same direction, i.e., the elastic shoulder 21607 of the driving connector 21603 is elastically deformed to disengage the end of the elastic shoulder 21607 from the latch 21605, so that the first transmission member 2167 cannot be further rotated, and the collet pushing tube 230 cannot further move axially, thereby preventing the distal collet 235 from further moving and damaging the collet module 23.

Referring to fig. 8 and 13-14, in the initial state, the locking member 2187 of the probe movement control module 218 is fastened to the first housing 211, the probe movement operation member 2180 is located in the guide slot 2116 near the proximal end, and the distal end of the probe 260 retracts into the proximal chuck 231. As shown in fig. 13, when the probe moving operation member 2180 is pressed to disengage the locking member 2187 from the first housing 211, the second connecting member 2182 is driven by the probe moving operation member 2180 moving toward the distal end, and the second connecting member 2182 drives the corresponding second collar 2157 to move toward the distal end along the axial direction of the rotating spindle 2150, so that the probe 260 moves toward the distal end along the axial direction, so that the distal end of the probe 260 extends out of the proximal chuck 231, and whether the valve leaflet is effectively clamped by the chuck module 23 is detected. As shown in FIG. 14, when the operating member 2180 is pulled proximally, the sliding member 2186 and the locking member 2187 are driven to move proximally together, so that the two second connecting members 2182 move proximally in the axial direction, and the two second connecting members 2182 respectively drive the two second collars 2157 to move proximally in the axial direction of the rotating spindle 2150, thereby driving the probe 260 to move proximally until the locking member 2187 is locked to the first housing 211 again, at which time, the distal end of the probe 260 retracts into the proximal collet 231. During the above-mentioned movement of the probe 260, the distance of the probe 260 axially moving can be known by observing the second viewing window 2118, thereby prompting the operator in what state the probe 260 is.

Referring to fig. 7, 8 and 16 to 18, when the pin module 25 is controlled by the pin lock control module 217, the pin lock control module 217 cooperates with the pin module 25 to control the pin 250 to move forward or backward. The axial movement of the pin handle 251 can drive the pin 250 to move axially, and the pin locking control module 217 is used for locking or unlocking the pin handle 251.

As shown in fig. 17 and 18, when the pushing member 2174 is moved downward by pressing the pin lock release operation member 2170, the pushing member 2174 pushes the locking member 2171 downward until the locking block 2175 is disengaged from the positioning ring groove 2512 of the pin handle 251, the elastic member 2176 is compressed and elastically contracted, and at this time, the pin lock release control module 217 is in the unlocking state, and the pin handle 251 can move axially to drive the pin 250 to move axially, so as to push or withdraw the pin to puncture the leaflet connecting suture or to take out the suture. When the pin releasing operation member 2170 is pressed again, the elastic member 2176 is elastically restored to push the locking member 2171, the pushing member 2174 and the pin releasing operation member 2170 to be restored, and the locking block 2175 is inserted into the positioning ring groove 2512 of the pin handle 251 again to lock the pin handle.
