Description

Operation ligature forceps

Technical Field

The invention relates to a surgical instrument, in particular to surgical ligation forceps.

Background

Shock and even death from bleeding during surgery is one of the major risks of surgery. The traditional surgical means achieves the effect of hemostasis by ligation, suture or compression of blood vessels, the metal or plastic clamp hemostasis which appears in recent years is a novel hemostasis mode, the speed of the hemostasis mode is greatly improved compared with the traditional mode, and the speed of the operation and the firmness and stability of ligation directly relate to the safety of the operation and the amount of bleeding; on the other hand, the metal or plastic clip has good histocompatibility and smaller inflammatory reaction than silk thread. However, in the prior art operation, it is often found that the combination between the titanium alloy metal clip used and the clamped tissue is not tight enough, and the combination between the metal clip and the clamped tissue belongs to a single-side closed end, and the other end is open, so that loosening and falling are easy to occur. The plastic clip used at present has larger elasticity, and the locking notch is not firmly combined, so that the plastic clip can be frequently loosened in operation. The prior metal or plastic clip ligation does not achieve satisfactory ideal effect.

Optionally, the push plate is convex, the push plate and the inner wall of the groove of the binding clip are nested with each other, the front end of the push plate is semi-arc-shaped, a second groove connected with the first groove in the binding clip is arranged in the center of the front end of the push plate, and the second groove can accommodate a ligation wire.

Optionally, the binding clip is arc-shaped and open.

Optionally, the device also comprises a container box for placing the titanium alloy metal wire.

The embodiment of the invention has the following beneficial effects:

the surgical ligature forceps of the invention mainly form a first forceps part and a second forceps part between the pull rod push plate component and the forceps body. In the work, when the first control piece drives the pull rod to move backwards, a first clamp part is formed between the pull rod and the clamp head, and at the moment, the metal wire is extruded by the first clamp part for the first time to clamp the tissue organ in a 360-degree surrounding manner; when the second control piece drives the push plate to move forwards, the push plate and the forceps heads form a second forceps part, at the moment, the titanium alloy metal wire is pushed and extruded by the second forceps part for the second time to form about 540-degree overlapping clamping on the clamped tissue organ, and the extruded metal wire forms a metal clamp with two closed ends, firm ligation and semi-circular arc shape. Therefore, the operation of the operation ligature forceps is simple, so that the titanium alloy metal wire can stably and firmly ligature blood vessels, bile ducts, vas deferens, lymphatic vessels, various arteriovenous vessels and the like to achieve the effect of complete closure.
