Description

Ligating clip with reinforced structure

Technical Field

The utility model relates to the field of medical appliances, in particular to a ligating clip with a reinforced structure.

Background

In modern surgery, ligation of blood vessels can be achieved by occluding the blood vessel with a ligation clip or suturing the blood vessel with a surgical thread. The ligation of blood vessels using surgical sutures requires complex manipulation of the needle and suture to form the knot required to ligate the blood vessel. Such complex procedures are not only time consuming, but also require a high level of skill on the part of the physician, especially in endoscopic procedures where space and visibility are limited. In contrast, ligation clips are relatively easy and quick to apply. Thus, the use of ligation clips in endoscopic surgical procedures has increased dramatically.

The ligature clamp is usually made of high polymer materials, is V-shaped belt lock catch structure, places in the base in advance, and ligature clamp both ends grow respectively has draw-in groove and barb, snatchs the ligature clamp with the clip applier during the use, after the ligature clamp wraps the blood vessel or body cavity tissue completely, applys sufficient power on the clip applier handle, and the ligature clamp atress effect is closed afterwards, and the barb slides in the draw-in groove, finally ligates blood vessel or body cavity tissue forever and closes.

Traditional ligature presss from both sides there is the not enough problem of installation closed back intensity, and there is cracked problem in the influence of vascular wall lateral action force easily after the product is closed, not only can influence the normal clear of operation, leads to the operating time to delay, endangers patient's life safety constantly even, and this has brought very big potential safety hazard for the patient, has also brought pressure in mind for the operation doctor simultaneously.

Disclosure of Invention

The utility model aims to provide a ligating clip with a reinforced structure, which can effectively avoid the problem of insufficient product strength.

The purpose of the utility model is realized by the following technical scheme: the utility model provides a take ligature of strenghthened type structure to press from both sides, it includes arm lock and lower arm lock, the rear end fixed connection of going up arm lock and lower arm lock, its front end is through the locking structure locking each other, the section of going up arm lock and lower arm lock is "protruding" shape, and its clamping face widens, and the relative narrowing formation stiffening rib in back.

Compared with the prior art, the utility model has the advantages that:

1. the sections of the upper clamping arm and the lower clamping arm are both in a convex shape, the clamping surfaces of the upper clamping arm and the lower clamping arm are widened, the clamping area and the cross section area of the upper clamping arm and the lower clamping arm are increased while the safety and the effectiveness of products are not influenced, the strength of the upper clamping arm and the lower clamping arm can be improved by the reinforcing ribs on the back surfaces of the upper clamping arm and the lower clamping arm, and the problem that the strength of the products is insufficient after the products are installed and closed is effectively solved.

2. The clamping columns are arranged on two sides of the reinforcing rib, and the reinforcing rib area corresponding to the clamping columns is further thickened to form the clamping reinforcing part, so that the problem of fracture of the ligation clip caused by excessive force applied by the clip applier can be solved, and the stability of the ligation clip in the operation process is effectively improved.
