Abstract

The utility model is related to medical assistive device technical field, more particularly to a kind of self-locking suture.Including connecting line and lock wire, the line head end that connects is connected with puncture and lead needle, and tail end is connected with the lock wire head end, and the lock wire outer surface is shiny surface, be embedded with multiple " V " shape flexure strips in the lock wire, the opening direction of the " V " shape flexure strip with connect in opposite direction.Further, the lock wire tail end is connected with lock.Further, there is sawtooth on the " V " shape flexure strip.Using the beneficial effects of the utility model it is：In thoracic cavity, abdominal cavity and ESS, convenient suture knots, time saving and energy saving.

Description

A kind of self-locking suture

Technical field

The utility model is related to medical assistive device technical field, more particularly to a kind of self-locking suture.

Background technology

Over the past decade, surgical suturing techniques have obtained rapid development, especially in thoracic cavity, abdominal cavity and endoscope hand In art.

According to incompletely statistics, the real time of a lot of operations is a half or thirds time of whole surgical procedure, The remaining most of the time is used in suture, and sewing process, there are most times to be used in knotting again, this process is in chest Particularly evident in chamber, abdominal cavity and ESS.The plenty of time is not only consumed, limited medical resource is also created and is wasted, Heavy burden is brought to this medical institutions that can't bear the heavy load.

Utility model content

The utility model is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of self-locking suture.

The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of self-locking suture, including connect line and Lock wire, the line head end that connects are connected with puncture and lead needle, and tail end is connected with the lock wire head end, and the lock wire outer surface is Shiny surface, is embedded with multiple " V " shape flexure strips in the lock wire, the opening direction of the " V " shape flexure strip with connect direction On the contrary.

Further, the lock wire tail end is connected with lock.

Further, there is sawtooth on the " V " shape flexure strip.

Using the beneficial effects of the utility model it is：In thoracic cavity, abdominal cavity and ESS, convenient suture knots, and saves time Laborsaving.

Specific embodiment

Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality New, it is not intended to limit scope of the present utility model.

As shown in figures 1-4：A kind of self-locking suture, including connecting line 2 and lock wire 3, described connect 2 head end of line and wears Draw pin 1 is connected, and tail end be connected with 3 head end of the lock wire, and 3 outer surface of the lock wire is shiny surface, and the lock wire 3 is embedded Be provided with multiple " V " shape flexure strips 5, the opening direction of the " V " shape flexure strip 5 with connect in opposite direction；

3 tail end of the lock wire is connected with lock 4.

There is sawtooth on the " V " shape flexure strip 5, increase frictional force, make suture easily locked.

Operation principle of the present utility model is：When thoracic cavity, abdominal cavity and ESS are sutured, puncture and lead needle 1 guides self-locking Suture is sutured, and when suture is completed, puncture and lead needle 1 penetrates lock 4, pushes lock wire 3, due to opening for the " V " shape flexure strip 5 Mouthful direction with connect in opposite direction, so under force, 3 surface of lock wire can form projection, engage with lock 4 and be difficult to take off Fall, 3 outer surface of the lock wire is fastening light face, will not pierce out the " V " shape flexure strip 5 because of firmly excessive, cause Unnecessary damage, suture are completed without laborious knotting.

Preferred embodiment of the present utility model is the foregoing is only, not in order to limit the utility model, all in this practicality Within new spirit and principle, any modification, equivalent substitution and improvements that is made etc. should be included in guarantor of the present utility model Within the scope of shield.

Claims
