the absorption clamping assembly 202 is made of degradable polymer material in human body, specifically, the degradable polymer material in human body can be poly (p-dioxanone).

In order to facilitate the use of the absorbable clip, the sheath 103 and 203 are connected together by a plastic sheath, so that the absorbable clip and the metal clip are integrated.

When the disposable absorbable clamp is used, the disposable absorbable clamp is inserted into a pore canal of a gastroscope accessory and enters an abdominal cavity, under the condition of endoscope visibility, the metal clamp firstly extends out, the metal clamp handle drives the metal clamp clamping component to extend out of the sheath tube, the metal clamp driving component is pushed forwards to open the metal clamp clamping component, the metal clamp handle is rotated clockwise or anticlockwise, the clamping component is controlled by the connecting component to simultaneously rotate in the same direction, and tissues or blood vessels are accurately clamped at a proper angle; then stretching out the absorbable clamp, specifically, driving and adjusting the sheathing-out distance of the absorbable clamp assembly stretching out of a sheathing canal of the outer sheath of the absorbable clamp by an absorbable clamp handle, opening the absorbable clamp clamping assembly by pushing the absorbable clamp driving assembly forwards, rotating the absorbable clamp handle clockwise or anticlockwise, controlling the clamping assembly to rotate in the same direction through the connecting assembly, adjusting the direction, accurately clamping tissues or blood vessels adjacent to the metal clamp, and then pulling the driving assembly backwards until the driving assembly is tightly attached to the handle, so that the absorbable clamp assembly can be released; and loosening the metal clip, withdrawing the metal clip from the sheath tube outside the digestive endoscope, and withdrawing the digestive endoscope integrally.

The metal clamp clamping assembly 102 rotates by 360 degrees through the rotation of the metal clamp handle 101; the absorption clamping assembly 202 rotates by 360 degrees through the absorption clamping handle 201; facilitating accurate gripping of the tissue or vessel by the metal clip gripping assembly 102 and the absorbent gripping assembly 202. The absorbent gripping assembly 202 releases the absorbent gripping assembly via the absorbent gripper drive assembly 204, facilitating the final separation of the gripping assembly from the unitary disposable absorbent gripper;

the metal clamp clamping assembly 102 comprises two metal clamp clamping arms which are oppositely arranged, and the two metal clamp clamping arms are driven by the metal clamp driving assembly to approach or move away from each other; the metal clip clamping arm comprises a metal clip first element 1021 and a metal clip second element 1022 which are connected with each other, the metal clip first element 1021 is arranged at one end of the metal clip second element 1022 far away from the metal clip driving component 104, an included angle alpha is formed between the metal clip first element 1021 and the metal clip second element 1022, namely the metal clip first element 1021 and the metal clip second element 1022 form a hook-like structure, the included angle alpha is preferably an obtuse angle, so that the tissue or blood vessel can be clamped, meanwhile, the tissue or blood vessel is prevented from being damaged, the tissue or blood vessel is clamped by the metal clip clamping arm conveniently, and the generation of the slipping phenomenon of the metal clip clamping arm is reduced.

The first member 1021 and the second member 1022 are integrally formed, so that the structural strength of the clamping arm is increased. Be equipped with a plurality of bosss 1023 on the metal clip second element 1022, boss 1023 is semi-circular, increases the frictional force of metal clip centre gripping arm, reduces the probability that tissue or blood vessel slippage on the metal clip centre gripping arm, realizes that the metal clip centre gripping arm is to the accurate clamp of tissue or blood vessel firmly.

Absorbent gripper assembly 202 comprises absorbent first gripper arm 201 and absorbent second gripper arm 202; the absorbing first clamping arm 201 is a vertical rod; the absorbing second clamping arm 202 comprises an absorbing first element 2021 and an absorbing second element 2022, the absorbing first element 2021 is a vertical rod, the absorbing second element 2022 is a hook structure, the absorbing second element 2022 is connected with the absorbing first element 2021, and the absorbing second element 2022 is arranged on one end of the absorbing first element 2021 far away from the absorbing clamp driving assembly 204; by absorbing the hook structure of the absorbing second element on the second clamping arm, the absorbing clamp has a larger clamping force, and the possibility that tissues or blood vessels slide off the absorbing clamp is reduced.

By rotating the metal clip handle 101 clockwise or counterclockwise, the rotational force is transmitted to the metal clip clamping assembly 102 through the metal clip connecting assembly 105, which drives the metal clip clamping assembly to rotate. The metal clamp clamping assembly can be adjusted to be perpendicular to the incision line through 360-degree rotation, so that tissues on two sides of the incision can be clamped, the metal clamp driving assembly is tightened, the metal clamp clamping assembly is driven to be closed, and the incision is closed.

By rotating the suction clip handle 201 clockwise or counterclockwise, the rotational force is transmitted to the suction clip holding assembly 202 through the suction clip connecting assembly 205, thereby driving the entire suction clip assembly to rotate clockwise or counterclockwise. When the metal clip closed the incision, stretched out this moment and can absorb the clamp, slowly be close to the incision that the metal clip closed, opened and absorbed the centre gripping subassembly, if the angle that absorbs the centre gripping subassembly is not perpendicular with the incision, can absorb the centre gripping subassembly through rotatory and make and absorb centre gripping subassembly and incision perpendicular, then the pincers grasp the incision to release and absorb the centre gripping subassembly, then loosen the metal clip centre gripping subassembly, the incision just can be absorbed and press from both sides the front end firmly and close this moment.

This application first step utilizes the metal clip to press from both sides incision both sides tissue and holds together, recycles and can absorb to press from both sides in the other incision tissue of cliping of next-door neighbour metal clip, releases to fall and can absorb and press from both sides front end clamping part, and the incision is just closed by the clamp forever.
