Abstract

The utility model provides an operation seam needle belongs to the medical instrument field. It is unstable that it has solved current seam needle centre gripping, and the unsafe problem of clamping position. This operation seam needle all is circular shape needle point, needle body and backshank including the cross -section, and needle point and backshank are established at the both ends of needle body, and are connected with the stylolite on the backshank, and the needle body directly is greater than the needle footpath of needle body respectively with the needle of needle point junction and backshank junction, on the needle body still the cover have a holding ring, the surperficial and holding ring inner wall of needle body is equipped with the friction line of mutually supporting respectively, is equipped with the breach that communicates holding ring inner wall and holding ring outer wall on the holding ring. Positioning adjustment ring position at first as required, during the use, arrange the needle forcep in breach on, the needle forcep can grasp the friction line on needle body surface, plays the effect of location needle forcep through the holding ring, abbot's needle pliering can be stabilized to the friction line, the line that rubs simultaneously can also the stable position fixing ring, therefore the needle forcep centre gripping is stable, and clamping position is accurate at every turn.

Description

A kind of operation needle

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of operation needle.

Background technology

Suture needle is one of articles for use of operation indispensability, vital effect is played in operation, all kinds of suture needle all belongs to precision instruments, when suture needle is selected in operation, according to the fragile degree of bodily tissue, internal organs and blood vessel etc., must be noted that the sharpness of needle point and the size of pinprick when selecting, avoid the wound causing tissue, according to the depth organizing internal organs position, the angle of bend of suture needle when selecting, should be noted.

But existing operation needle smooth surface, therefore the frictional force between operation needle and needle forceps is less, causing medical worker to hold suture needle at use needle forceps carries out in the process of performing the operation, careless a little, just likely suture needle is dropped, and doctor can only clamp on a certain position of suture needle by rule of thumb, if but clip position is not right, then be easy to stressed symmetry initiation suture needle fracture, the carrying out of impact operation, even likely can cause serious consequence to patient.

Utility model content

The purpose of this utility model is for the above-mentioned problems in the prior art, provides a kind of by needle forceps stable holding, and clip position operation needle accurately.

The purpose of this utility model realizes by following technical proposal: a kind of operation needle, comprise all rounded needle point in cross section, needle body and backshank, described needle point and backshank are located at the two ends of needle body, and backshank is connected with stitching thread, it is characterized in that: needle body is greater than the pin footpath of needle body with the pin footpath of needle point junction and backshank junction respectively, on described needle body, also cover has locating ring, described needle body surface and locating ring inwall are respectively equipped with the friction stricture of vagina cooperatively interacted, and described locating ring is provided with the breach being communicated with locating ring inwall and locating ring outer wall.

First as required locating ring position is adjusted, during use, needle forceps is placed on breach, needle forceps can clamp the friction stricture of vagina on needle body surface, played the effect of location needle forceps by locating ring, friction stricture of vagina can stablize abbot's needle pliering, and friction stricture of vagina can also stable position ring simultaneously, therefore needle forceps clamping is stable, and each clip position is accurate.

In above-mentioned a kind of operation needle, described locating ring two ends and needle body surface, and needle body is seamlessly transitted by annular spigot surface with needle point junction and backshank junction respectively.

Seamlessly transitted by spigot surface, avoid locating ring and needle body and needle point junction and backshank junction and organize pullling.

In above-mentioned a kind of operation needle, described locating ring is circumferentially angularly provided with the breach described in four.

Therefore positioning clamping is facilitated.

In above-mentioned a kind of operation needle, on described needle body, cover has the locating ring described in two.

Therefore facilitate and pull suture needle back and forth.

Compared with prior art, this utility model tool has the following advantages:

Detailed description of the invention

Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but this utility model be not limited to these embodiments.

As illustrated in fig. 1 and 2, a kind of operation needle of this utility model, comprise all rounded needle point in cross section 1, needle body 2 and backshank 3, needle point 1 and backshank 3 are located at the two ends of needle body 2, and backshank 3 is connected with stitching thread, needle body 2 is greater than the pin footpath of needle body 2 with the pin footpath of needle point 1 junction and backshank 3 junction respectively, on needle body 2, also cover has locating ring 4, needle body 2 surface and locating ring 4 inwall are respectively equipped with the friction stricture of vagina 21 cooperatively interacted, and locating ring 4 is provided with the breach 41 being communicated with locating ring 4 inwall and locating ring 4 outer wall.

Further, locating ring 4 two ends and needle body 2 surface, and needle body 2 is seamlessly transitted by annular spigot surface 42 with needle point 1 junction and backshank 3 junction respectively.Locating ring 4 is circumferentially angularly provided with four breach 41.On needle body 2, cover has two locating rings 4.

First as required locating ring 4 position is adjusted, during use, needle forceps is placed on breach 41, needle forceps can clamp the friction stricture of vagina 21 on needle body 2 surface, played the effect of location needle forceps by locating ring 4, friction stricture of vagina 21 can stablize abbot's needle pliering, and friction stricture of vagina 21 can also stable position ring 4 simultaneously, therefore needle forceps clamping is stable, and each clip position is accurate.

Specific embodiment described herein is only to the explanation for example of this utility model spirit.This utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.

Although more employ the term such as needle point 1, needle body 2, friction stricture of vagina 21, backshank 3, locating ring 4, breach 41, spigot surface 42 herein, do not get rid of the probability using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with this utility model spirit.
