Abstract

One pin is multi-thread is linked into formula operation needle, belongs to technical field of medical instruments.In order to overcome the little deficiency not easily passing through and once can only wear single line of existing Medical operating needle through wires hole, this utility model expands pin hole scope in operating needle orifice design district, at pin hole region tail end fluting shape mouth, design in pairs in pin hole district multiple with pin hole two wall be substrate, the relative valve in direction, pin hole district is divided into multiple line region of receiving.This utility model, in use without threading, adopts and is linked into mode, simple and fast, can facilitate the quick good quality work of operating-table nurse; This utility model can many hanging wires, sew up a pin, can bring many surgical threads into, easy to operate, are conducive to shortening operating time, reduce the probability of tissue injury, infection and scar hyperplasia.Be particularly useful in particular cases, operating room has a power failure suddenly or field, region of war operation first aid etc.

Description

One pin is multi-thread is linked into formula operation needle

Art

This utility model relates to technical field of medical instruments, is a kind of novel Medical operating needle.

Background technology

At present, existing Medical operating needle is generally made up of needle point, needle body, on pin, usually have a closed through wires hole.During use, in operation process, general by nurse's threading on operating-table, for operative doctor.Existing Medical operating needle has following deficiency: because through wires hole is little, and hole is closed type, is unfavorable for passing through, and requires strict to nurse's vision on operating-table and operating room light; Owing to only having a through wires hole, during stitching, single line generally can only be with to pass through, in some cases, require the quick repeatedly threading of nurse, doctor frequently sews up, and has increased the weight of tissue injury, has added patient suffering.These shortcomings, affect operation progress, extend operating time, waste a large amount of manpower and materials, cause unnecessary injury to patient.

Summary of the invention

In order to overcome the little deficiency not easily passing through and once can only wear single line of existing Medical operating needle through wires hole, this utility model provides a kind of novel Medical operating needle, this pin is not only without threading, take the mode of being linked into, and can many be linked into, a pin can be sewed up bring many different surgical threads into and organize needed for field of operation, and can differentiate clear, avoid mutual winding.This scheme reduces the degree of the strict demand to theatre sister's vision and operating room light, is conducive to shortening operating time, reduces tissue injury, reduces postoperative infection probability, improves success rate of operation, saves a large amount of manpower and materials.

This utility model solves the technical scheme that its technical problem adopts: in operating needle orifice design, district expands pin hole scope, at pin hole region tail end fluting shape mouth, design in pairs in pin hole district multiple with pin hole two wall be substrate, the relative valve in direction, in ladder-type structure, v shape arranges, and pin hole district is divided into multiple line region of receiving.Line crack is received in valve cusps indwelling, and crack mouth opens to the direction that needle body afterbody is relative, valve rational design, avoid operation needle perform the operation carry out different actions time surgical thread deviate from the other direction may.Arc angling is all designed in flute profile mouth, Na Xianqu and linear contact lay position, to adapt to the action of different directions in operation process and to avoid the damage of line.On operating-table, nurse, according to the needs of operative doctor, holds needle handle with needle holder and passs in left hand, hold required surgical thread, be that "eight" shape is propped up surgical thread and is linked in pin hole afterbody groove with hand thumb, forefinger, then slightly firmly namely embed required Na Xianqu to valve orifice direction; As needed many different surgical threads, continuing to repeat above-mentioned action, being hung on the Na Xianqu needed for difference.

The beneficial effects of the utility model are, on operation needle, pin hole district tail end fluting shape mouth, without threading, adopts and be linked into mode, simple and fast, can facilitate the quick good quality work of operating-table nurse, even can look lower operation blind; The multiple paired valve of design forms multiple line region of receiving in pin hole, can many hanging wires, sews up a pin, can bring many surgical threads into, convenient to operation, is conducive to shortening operating time, reduces the probability of tissue injury, infection and scar hyperplasia.Be particularly useful in particular cases, operating room has a power failure suddenly or field, region of war operation first aid etc.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Fig. 1 is the multi-thread vertical section structural map being linked into formula operation needle of a pin, is the schematic diagram carried out for round needle needle body.

Fig. 2 is the vertical section structural map of Medical operating needle pin hole, is the partial enlargement at pin hole position in Fig. 1.

In Fig. 1,1 is needle point, and 2 is needle bodies, and 3 is pin holes.Needle point (1), needle body (2) are same material.Needle point (1), needle body (2) can adopt needle point and the needle body designs of existing Medical operating needle.The needle point of existing Medical operating needle, refers to the needle point of the pins such as cutting needle common on market, round needle; The needle body of existing Medical operating needle, refers to the needle body of the shapes such as circle common on market, flat, groove type.Needle point of the present utility model and needle body, can adopt the multiple combination of existing Medical operating needle needle point, the various shape of needle body.This utility model can have different lengths, multiple radian.

Pin hole (3) is at needle body afterbody.Pin hole (3), compared with existing Medical operating needle, takes new design, and its partial enlarged drawing as shown in Figure 2.

In Fig. 2,4 is valves, and 5 is flute profile mouths that pin hole district tail end is offered, and 6 is pin hole lateral inner wall.Compared with existing Medical operating needle, this utility model pin hole strengthens and lengthens.Pin hole district tail end offers flute profile mouth (5), is hanging wire inlet region.Pin hole inside is provided with multipair valve (4) structure of stepped, " V " shape arrangement, pin hole is divided into multiple region A, B, C etc. of receiving line.Flute profile mouth (5), receive line region A, B, C and linear contact lay position and all design arc angling, to adapt to the action of different directions in operation process and to avoid the damage of line.Valve (4) rational design, is less than 70 degree with the angle of pin hole lateral inner wall (6), surgical thread dystopy during to prevent different directions action in operation process.Line crack is received in valve (4) most advanced and sophisticated indwelling, and crack mouth opens to the direction that needle body afterbody is relative, is convenient to surgical thread and enters from entrance crack and receive line region (such as A, B, C etc.).

Detailed description of the invention

Specific embodiment composition graphs 2 illustrates.In operation process, on operating-table, theatre sister's right hand is held needle holder pincers and is held needle body and pass in left hand, and the right hand is that "eight" shape is propped up surgical thread and is linked into flute profile mouth (5), receives line region A or B or C downwards needed for slightly firmly slipping into.Needed for operation, if desired a pin is multi-thread, can repeat above-mentioned action, from flute profile mouth (5) be linked into respectively many different surgical threads to needed for receive line region.
