Detailed Description
The utility model will be further described with reference to the accompanying drawings and detailed description below:
1-4, a surgical clip for stomach surgery comprises a clip head assembly 10 and a clip arm assembly 20, wherein the clip head assembly 10 comprises a clip head shell 11, a first holding arm 12, a second holding arm 13 and a linkage rod 16, one end of the first holding arm 12 is formed as a first holding end, and the other end of the first holding arm 12 is formed as a connecting end. Correspondingly, one end of the second holding arm 13 is formed into a second holding end, the other end of the second holding arm 13 is fixedly connected with the chuck shell 11, and the first holding arm 12 is hinged with the second holding arm 13 through a rotating shaft 14; one end of the linkage rod 16 is movably connected with the chuck shell 11 in a penetrating way; and is connected with the connecting end; the other end of the link lever 16 is formed as a link end, so that the link lever 16 can be moved in the collet housing 11 by rotation of the first grip arm 12.
In addition, the clamping arm assembly 20 includes a clamping seat 24, a pushing rod 23, two linkage arms 25, and two clamping arms 21, wherein the two clamping arms 21 are respectively hinged to two sides of the clamping seat 24. One end of the clamp arm 21 is formed as a hinge end; the other ends of the clamping arms 21 are formed as clamping ends, one ends of the two linkage arms 25 are respectively hinged to the hinged ends of the two clamping arms 21, the other ends of the two linkage arms 25 are connected with the pushing rods 23, and the pushing rods 23 are connected with the linkage ends.
On the basis of the structure, when the surgical clip for stomach surgery is used, an operator can hold the first holding end and the second holding end of the surgical clip, the first holding end rotates relative to the second holding end, the linkage rod 16 connected with the first holding end can be pulled or pushed in the rotation process of the first holding end, the linkage rod 16 can move relative to the chuck shell 11, and the pushing rod 23 connected with the linkage rod 16 is pushed or pulled to move.
After the push rod 23 is pushed to move close to the clamping seat 24, the two linkage arms 25 hinged with the push rod 23 are opened relatively, so that the clamping ends of the two clamping arms 21 hinged with the push rod are driven to approach, and clamping of human tissues is realized, otherwise, if the push rod 23 is pulled to move away from the clamping seat 24, the two linkage arms 25 hinged with the push rod 23 are relatively close, and further the clamping ends of the two clamping arms 21 hinged with the push rod are driven to move away from each other, so that lowering of the human tissues is realized.
Because the two clamping arms 21 are opened or clamped through the mutual linkage of the linkage arm 25 and the clamping arms 21, the output of the rotation motion is realized by two sections of force arms, the linkage arm 25 is used as the rotation force assisting arm of the clamping arms 21, the opening and closing of the clamping arms 21 are more labor-saving, the output of the rotation motion is more flexible, and the rotation range of each section of force arm is relatively smaller, so that the opening and closing angle adjusting range of the clamping arms 21 is more flexible.
Further, specifically, in order to facilitate connection between the two linkage arms 25 and the push rod 23, a push block 231 may be disposed at an end of the push rod 23, and the end of the two linkage arms 25 are respectively hinged to two sides of the push block 231, so that when the linkage rod 16 pushes the push rod 23 connected with the push block, the push block 231 of the push rod 23 can drive the two linkage arms 25 connected with the push rod to approach or depart from the clamping seat 24, thereby driving the two clamping arms 21 to open or close.
Further, an elastic member 26 may be disposed between the pushing block 231 and the holder 24, and the elastic member 26 may provide an elastic stress for driving the pushing block 231 away from the holder 24. When the two clamping arms 21 are driven to approach each other for clamping operation, the pushing block 231 can move near the clamping seat 24, the pushing block 231 moves near the clamping seat 24, one ends of the two linkage arms 25 can be opened relatively, the other ends are driven to be far away from each other, the hinged ends of the two clamping arms 21 connected with the two linkage arms are driven to be far away from each other, and the clamping ends of the other ends of the two clamping arms 21 are driven to approach each other for clamping operation, so that the elastic component 26 is in a compressed state in the process.
When the clamping arms 21 are loosened, the elastic component 26 is reset, the pushing block 231 can be driven to reset, the pushing block 231 is far away from the clamping seat 24 under the action of elastic stress provided by the elastic component 26, and then the ends, connected with the two hinged ends, of the two linkage arms 25 are driven to be close to each other, and the clamping ends of the two linkage arms 25 can be far away from each other to realize opening.
In this way, the return operation of the link lever 16 can be realized by the return of the elastic member 26, and the return is more rapid. Of course, the first holding end can be driven by a human hand to rotate relatively far away from the second holding end, so as to realize the direct pull-back of the linkage rod 16.
Specifically, the elastic component 26 is a spring, one end of the spring is connected with the pushing block 231, the other end of the spring is connected with the clamping seat 24, so that the restoring of the pushing block 231 can be realized through the rebound of the spring, and the spring can be more easily deformed and rebound compared with materials with elastic restoring performance such as elastic rubber blocks.
Further, the arm clamping assembly 20 in the present embodiment further includes an arm clamping housing 22, the arm clamping housing 22 is provided with a through-connection cavity 221, and the clamping seat 24 is mounted at one end of the through-connection cavity 221, and the clamping end extends out of the through-connection cavity 221; the push rod 23 is movably connected to the through-connection cavity 221 and connected to the linkage end, that is, the push rod 23 can be connected to the through-connection cavity 221 in a penetrating manner, the through-connection cavity 221 limits its own axial movement, so as to prevent the shift during the pushing or pulling process of the linkage rod 16, and the movement process is more moving.
And the clamping seat 24 and the linkage arm 25 serving as the assembly foundation of the clamping arm 21 are all installed in the through-connection cavity 221, the clamping end of the clamping arm 21 extends out, the clamping arm shell 22 can prevent the internal structure from being exposed, and the influence on the operation in the clamping process is reduced.
Further, the chuck housing 11 may be further provided with a through sleeve 15, the linkage rod 16 is movably connected in the through sleeve 15, the arm-clamping housing 22 is sleeved outside the through sleeve 15 when the arm-clamping assembly 20 and the chuck assembly 10 are assembled, and the linkage rod 16 is connected with the pushing rod 23, so that linkage can be realized, that is, the connecting structure is covered by the chuck housing 11 and the arm-clamping housing 22.
It will be apparent to those skilled in the art from this disclosure that various other changes and modifications can be made which are within the scope of the utility model as defined in the appended claims.
