Description
Technical Field
The utility model relates to a ligature clamp, which belongs to surgical implant medical appliances clinically and is suitable for ligaturing and closing blood vessels and body cavity tissues during human body surgery.
Background
In human surgery, once a lesion is found in the human body, it needs to be excised, and during the excision surgery, the internal organs need to be temporarily closed, even permanently closed.
The prior art has the defects that:
firstly, close the position to internal suture and close, its defect is that operation time is long, and the operation degree of difficulty is big, requires that the doctor has very strong suture knotting technique, in case the line is tied and not tightly can cause the pine or take off the line phenomenon, causes patient to bleed, and wound healing is slow moreover.
The other is a tissue clip, such as a commonly used metal clip (titanium clip, silver clip), which is generally a U-shaped metal clip. In clinical use, a special tissue clip applier is used to insert the clip into the jaws of the tissue clip applier head, which is then released, i.e., the jaws of the tissue clip applier are clamped, and the tissue clip is withdrawn, and the U-shaped clip is tightened against the tissue to be closed. The metal clip is simple to use and has definite curative effect, so that the metal clip is widely applied clinically. The defect is that after the U-shaped titanium clamp is deformed, the U-shaped titanium clamp is not self-locked at the closed position, and the U-shaped titanium clamp slips under the action of elastic recovery force of clamped tissues, so that the U-shaped titanium clamp not only cannot close the closed tissues, but also easily slips to the inside to become foreign matters, and tissue adhesion and obstruction are easily caused at important blood vessels and nerve parts. Also, excessive clamping force of the metal clip can burst tissue, which can cause surgical failure.
Third, other tissue clips, such as plastic tissue clips, have poor elasticity and strength, and can press the tissue outward when the clip is fully closed, resulting in a poor closure, sometimes even pinching-off of hardened ducts, such as hardened cystic ducts.
Disclosure of Invention
The utility model aims at the above-mentioned weak point, provide a ligation clamp, through setting up on the ligation clamp bow-shaped arm and ligation clamp bow-shaped arm down be provided with upper and lower back taper body, upper and lower bow-shaped arm triangular groove (angle 60-120) respectively on the bow-shaped arm when pressing from both sides closed tissue blood vessel, close the tissue blood vessel to the compression in the middle of the triangular groove, form after the compression that to press from both sides two outsides at closed tissue blood vessel position and flatten, the middle tissue blood vessel is bloated to the triangular groove in, tissue blood vessel forms when the compression is pressed from both sides closed and flattens-bloated-flattens the shape like this, just can not remove along vascular direction, slippage when the tissue blood vessel is pressed from both.
