Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, especially a continuous firing ligature clamp with built-in memory wire. BACKGROUND

[0002] In surgical minimally invasive surgery, ligature clamps are often used to clamp and close tubular tissues in the human body. The ligature clamps need to be used in cooperation with special clamping instruments. The space of the abdominal wall puncture device sleeve used in surgical minimally invasive surgery is small, and the structure of the continuous firing ligature clamp is irregular. In the natural relaxed state, the size is large, and it cannot pass through the puncture device sleeve. It must pass through the puncture sleeve in a compressed state, and then relax after entering the body cavity, so as to ligate and close the tubular tissues in the human body. When the continuous firing ligature clamp is inside the continuous firing clamping forceps, it may be in a closed state for a long time, and at this time, the ligature clamp may not open and close in time during use, resulting in accidents during surgery.

[0003] Therefore, it is a difficult problem to preinstall the ligature clamp in the reusable continuous firing clamping forceps to achieve regular arrangement, present a compressed state when passing through the puncture sleeve, restore to a relaxed state when being used to close, and be continuously transported and effectively closed in sequence.

The first clamping arm and the second clamping arm are connected through the connecting part. In the initial state of the continuous firing ligature clamp with built-in memory wire, the first clamping arm, the second clamping arm and the connecting part form a V-shaped structure as a whole. A U-shaped hole is arranged in the middle of the connecting part. A clamping head is arranged at the end of the first clamping arm away from the connecting part. A clamping hook is arranged at the end of the second clamping arm away from the connecting part. A groove is arranged in the middle of the front end of the clamping head. The clamping hook and the second clamping arm form a locking groove. The clamping head and the clamping hook are detachably connected through mutual cooperation. Memory wire is arranged inside the first clamping arm, the second clamping arm and the connecting part. The memory shape of the memory wire is a V-shaped structure as a whole.

[0006] Further, two clamping bosses are arranged on both sides of the position of the clamping head on the first clamping arm. The clamping bosses protrude from the first clamping arm at the position of the clamping bosses. The cross section of the clamping bosses is in the shape of a water droplet. In the initial state of the continuous firing ligature clamp, the sharp head faces the direction of the clamping hook.

[0007] Further, a clamping cylinder is arranged on the second clamping arm. The clamping cylinder protrudes from the outer edge of the second clamping arm at both ends. In the closed state of the continuous firing ligature clamp, the clamping bosses are located between the clamping cylinder and the clamping hook.

[0008] Further, the first clamping arm and the second clamping arm are provided with a plurality of anti-skid edges on two mutually facing surfaces thereof.

[0020] Referring to Figures 1-4The embodiment provides a continuous shooting ligation clip with a built-in memory wire, which comprises a first clip arm 100, a second clip arm 200 and a connecting part 300, wherein the first clip arm 100 and the second clip arm 200 are connected through the connecting part 300; in the initial state of the continuous shooting ligation clip, the first clip arm 100, the second clip arm 200 and the connecting part 300 form a V-shaped structure as a whole; and a through U-shaped hole is arranged in the middle of the connecting part 300, so that the first clip arm 100 and the second clip arm 200 can be in relative contact through the bending of the connecting part 300, and the clamping purpose is achieved.

[0021] A clamping head 101 is arranged at the end of the first clip arm 100 away from the connecting part 300, a clamping hook 201 is arranged at the end of the second clip arm 200 away from the connecting part 300, a recess is arranged in the middle of the front end of the clamping head 101, the clamping hook 201 and the second clip arm 200 form a locking groove, and the clamping head 101 and the clamping hook 201 are detachably connected through mutual cooperation; through the mutual cooperation of the clamping head 101 and the clamping hook 201, the first clip arm 100 and the second clip arm 200 can be locked, and the ligation effect in the operation is achieved.

[0022] A memory wire 400 is arranged in the first clip arm 100, the second clip arm 200 and the connecting part 300, and the memory mode of the memory wire 400 is that, in the initial state of the continuous shooting ligation clip, the first clip arm 100, the second clip arm 200 and the connecting part 300 form a V-shaped structure as a whole; and the memory wire 400 can timely open the ligation clip when the memory wire 400 needs to recover to the memory mode.

[0023] In the clamping forceps of the continuous shooting ligation clip, the ligation clip is in a clamped state, and when the ligation clip is in this state for a long time, the ligation clip may not be naturally opened or the opening angle is small due to rigidity and other reasons, which is not conducive to the use in the operation process; at this time, the built-in memory wire 400 can help the ligation clip to be opened and opened to the memory position, and the memory position is the most suitable opening angle of the ligation clip, so that the ligation clip cannot affect the use due to the opening problem in the operation process.

[0024] Referring to Figures 1-4 Two clamping bosses 102 are arranged on the first clip arm 100 at the positions on both sides of the clamping head 101, the clamping bosses 102 protrude from the first clip arm 100, the cross section of the clamping boss 102 is in the shape of a water drop, and in the initial state of the continuous shooting ligation clip, the sharp head faces the direction of the clamping hook 201.

[0026] The clamping protrusions 102 and the clamping cylinders 202 create a clear view for the operation, improve the safety and success rate of the operation, and help to improve the stability of the ligature clip on the tissue, especially in the case where the clip needs to bear a certain tension. During the operation, the doctor can hold the clamping protrusions 102 and the clamping cylinders 202 by operating the clip applier, and the raised form can more easily fix the ligature clip in the appropriate position, and also indicate the position of the clip. In some cases, the clamping protrusions 102 and the clamping cylinders 202 can serve as markers to help the doctor identify the exact position of the ligature clip. The clamping protrusions 102 and the clamping cylinders 202 prevent the clip from opening accidentally. The raised design can prevent the ligature clip from opening accidentally during the operation, ensuring the safety of the operation.

[0027] Referring to Figures 1-4 The first clip arm 100 and the second clip arm 200 are provided with a plurality of anti-skid edges on the two surfaces facing each other. The anti-skid edges 102 help to compress the blood vessel wall and achieve hemostasis. Effective control of bleeding can reduce the risk of shock in patients due to bleeding.
