The end of the clamping control handle 13 in this embodiment extends out of the positioning sleeve 16 through the second through hole, and when the clamping operation is performed, the clamping control handle 13 is pulled to move relative to the holding handle 17, so as to drive the clamping connecting sleeve 12 to slide along the second sliding groove, and at the same time, drive the pair of second clamping rods connected with the clamping connecting sleeve 12 to move, so as to drive the pair of second chucks 2 connected with the front ends of the pair of second clamping rods to move towards the direction approaching or separating from the relative first chucks 1, thereby realizing the opening and closing actions.
When the second runner for installing the clip applying and connecting sleeve of the opening and closing device is located at the rear side of the first runner, since the clip applying and connecting sleeve is to be connected with the second clip applying rod, a pair of through holes for passing through a pair of second Shi Gagan 5 needs to be provided inside the distance adjusting and connecting sleeve 10. When the second sliding groove is arranged in parallel with the first sliding groove, the second clip applying rod 5 does not need to pass through the distance adjusting connecting sleeve, so that the distance adjusting connecting sleeve 10 does not need to be internally provided with a perforation.
In order to determine a reasonable clamping position according to the actual condition of the vessel ligation during the clamping operation, the adjustable-distance double-clamping clamp of the embodiment can further comprise a rotating device for respectively enabling the pair of first clamping rods 21, the pair of second clamping rods 5 and the distance adjusting rod of the distance adjusting device to be parallel and capable of rotating relative to the mounting sleeve 16 of the holding device.

Wherein, by rotating the rotary handle 8 relative to the setting sleeve 16, the pair of first clip applying rods 21, the pair of second clip applying rods 5 and the distance adjusting rod 4 are driven to rotate relative to the setting sleeve 16, the angle of application required during the ligation of blood vessels can be adjusted.
The rotary handle 8 may be inserted into the setting sleeve 16 with a gap between the rotary handle and the setting sleeve 16, or the rotary handle 8 may be screwed with the setting sleeve. The front end of the return spring of the opening and closing device can be propped against the tail end of the rotating handle, and a limit stop used for propping against the front end of the return spring can also be arranged on the inner wall of the placement sleeve.

Preferably, the distance adjusting connecting rod 14 is perpendicular to the distance adjusting rod 4, and the tail end of the distance adjusting connecting rod 14 is provided with a protruding expansion part for being clamped in the distance adjusting ring groove 18. When the rotary handle 8 rotates relative to the positioning sleeve 16 through external force, the distance adjusting rod 4 is driven to rotate, and the tail end of the distance adjusting connecting rod 14 connected with the distance adjusting rod 4 is always inserted into the distance adjusting ring groove 18 and moves circumferentially along the distance adjusting ring groove 18, so that the distance adjusting rod 4 can generate rotary motion relative to the distance adjusting connecting sleeve 10, namely, the rotary motion of the distance adjusting rod 4 relative to the positioning sleeve 16 is realized.
Similarly, in order to enable the pair of second clip applying rods 5 to rotate along with the rotating handle 8, as shown in fig. 10-12, at least one clip applying ring groove 19 is formed on the inner wall of the clip applying connecting sleeve 12 in a ring manner, and a clip applying connecting rod 15 slidably connected with the Shi Gahuan groove 19 is arranged at the tail end of the second clip applying rod 5. Preferably, clip applier bar 15 is perpendicular to second clip applier bar 5, and the distal end of clip applier bar 15 is provided with a protruding enlarged portion for snap-fit engagement within clip applier ring groove 19. When the rotary handle 8 rotates relative to the mounting sleeve 16 through external force, the second clip applying rod 5 is driven to rotate, and the tail end of the clip applying connecting rod 15 connected with the second clip applying rod 5 is always inserted into the clip applying ring groove 19 and moves circumferentially along the clip applying ring groove 19, so that the second clip applying rod 5 can generate rotary motion relative to the clip applying connecting sleeve 12, namely, the rotary motion of the second clip applying rod 5 relative to the mounting sleeve 16 is realized.
During design, the internal cavity of the placement sleeve and the positions of the components are reasonably arranged according to the actual arrangement positions of the two sliding grooves, so that the components of the opening and closing device and the components of the distance adjusting device cannot interfere.
When the adjustable double-clamp clip applier is adopted for clip applier operation, the clip applier is firstly in a natural state in an open state, the distance between a pair of first chucks and the distance between a pair of second chucks are both minimum, and the ligature clamp is installed in the state and is fixedly installed in a double-clamp box provided with a plurality of double clamps. During installation, the adjustable-distance double-clamp clip applier is opened, the upper and lower clamping grooves of the two pairs of clamping heads are respectively aligned with the double clamps in the double-clamping-seat box, the double pairs of clamping heads are slightly pushed, the two pairs of clamping heads are installed in the upper and lower clamping grooves of the two pairs of clamping heads of the clip applier, and a new pair of ligature clamps are installed after one time of use, so that the ligature clip applier is repeatedly used.
Next, the working principles of the adjustable-distance double-clamp clip applier according to the present embodiment for distance adjustment, clip applier operation, and azimuth adjustment will be briefly described.
And (3) distance adjustment: the distance adjusting control handle 11 is moved forwards and backwards to push the distance adjusting connecting sleeve 10 to send force to the distance adjusting rod 4, so that the angle between the pair of connecting rods 3 is adjusted, and the aim of adjusting the distance between the two groups of chucks is fulfilled.
Clamping operation: the clamping control handle 13 is moved back and forth to push the clamping connecting sleeve 12 to send force to the second clamping rod 5 to close the first clamping head 1 and the second clamping head 2, so that the clamping effect is achieved. Wherein, when the hand is released, the double clamp heads are in an open natural state due to the reset action of the return spring 9.
Azimuth adjustment: by using the rotary handle 8, the first clip applying rod, the second clip applying rod and the distance adjusting rod can rotate relative to the arranging sleeve 16 under the action of the parallel maintaining sleeve 20, so that the second Shi Gagan rotates around the respective centers in the circular distance adjusting connecting sleeve 11 and the distance adjusting rod in the clip applying connecting sleeve 12, thereby achieving rotation of any angle such as 360 degrees, and being suitable for vascular ligation under different conditions.
The distance-adjusting connecting sleeve 10 and the clamping connecting sleeve 12 of the embodiment are both limited on a sliding groove in the setting sleeve 16 to move linearly along the front-back direction. In addition, annular ring grooves 18 and 19 are formed in the inner walls of the distance-adjusting connecting sleeve 10 and the clamping connecting sleeve 12, and the distance-adjusting connecting rod 14 connected with the distance-adjusting rod and the head-side expansion end of the clamping connecting rod 15 connected with the second clamping rod are limited to be in the ring grooves respectively. Therefore, the distance adjusting connecting sleeve 10 and the clamping connecting sleeve 12 can drive the distance adjusting connecting rod 14 and the clamping connecting rod 15 to move back and forth.
