Description

Medical needle

Technical field

This utility model belongs to medical apparatus field, relates to operational tool, especially relates to a kind of Medical needle.

Background technology

Medical needle is mainly used in sewing up tissue and penetrating ligature. Pin hole on existing operation needle backshank is less, and during operation, threading is cumbersome, and in process, surgical thread easily departs from suture needle, so that needing repeatedly threading. And nearly backshank side is bifilar surgical thread during existing suture needle threading, it is impossible to use sub-thread surgical thread, increase the wound to patient. For deeper wound, generally requiring layer-by-layer suture, current practices person is substantially and determines the degree of depth of inserting needle with sensation by rule of thumb, if threading a needle deep stitching, it is easy to form dead space, if otch both sides depth of needle is inconsistent, then to cause the skin symmetry that coincide not enough. In operation process, if suture needle is lost, usually need to expend the substantial amounts of time, manpower looks for, the operating time of the surgical patient that so can extend, it is possible to miss the golden hour of patient, bring considerable distress for patient and family members.

In order to solve prior art Problems existing, people have carried out long-term exploration, it is proposed that solution miscellaneous. Such as, Chinese patent literature discloses the suture [application number: 201520233098.5] of a kind of crosspointer single line, and including angular pin, the needle rear end of angular pin has through wires hole, described through wires hole connecting sewing zygonema, and the described stitching thread other end connects round needle.

Above-mentioned scheme, owing to adopting single line to sew up, alleviates patient suffering, but, also at least there is following defect in the program: can only single use, be subject to the restriction of line length, thread-changing such as is wasted time and energy at the problem.

Utility model content

The purpose of this utility model is for the problems referred to above, it is provided that a kind of reasonable in design, simple in construction, and threading is easily and the Medical needle that not easily separates with suture needle of surgical thread.

For reaching above-mentioned purpose, this utility model have employed following technical proposal: Medical needle of the present utility model, including syringe needle, the needle body and backshank, backshank is horizontally set with the pin hole placed for line tieing of non-lateral direction penetrating backshank, pin hole connects between side and the backshank outer end of backshank outer end and is provided with a unwrapping wire groove, the width of unwrapping wire groove, less than the width of pin hole, is communicated with the inlet/outlet mechanism for line turnover unwrapping wire groove in the external world outside unwrapping wire groove. Surgical thread tieing can be facilitated to be placed in pin hole not easily drop out owing to pin hole does not extend through backshank, owing to when the width of unwrapping wire groove is easy to sew up less than the width of pin hole, surgical thread tieing is tightly abutted against unwrapping wire groove and pin hole linking part, sew up thus realizing single line, the misery significantly reducing patient is sewed up compared with two-wire, it is positioned at the inlet/outlet mechanism outside unwrapping wire groove and is easy to surgical thread turnover unwrapping wire groove, it is easy to when surgical thread falls short of, quickly it is reinstalled new surgical thread, or just backs off the surgical thread in suture needle when operation terminates rear.

Preferably, inlet/outlet mechanism include with unwrapping wire groove outside longitudinally through access way. Simple in construction, easily manufactured.

Preferably, outside access way, narrow with dovetail configuration connects. Facilitate the turnover of surgical thread.

Preferably, the width of access way is less than the Breadth Maximum of unwrapping wire groove, and the width in dovetail configuration width portion is more than the Breadth Maximum of unwrapping wire groove. What facilitate different thicknesses surgical thread looks for position and turnover.

Preferably, access way is vertical on outside unwrapping wire groove. Easily manufactured.

Preferably, the cross section of unwrapping wire groove and pin hole is all circular. It is easy to surgical thread turnover, decreases the abrasion to surgical thread.

Preferably, syringe needle and/or the needle body are provided with the scale portion of mark depths. Estimate depth of needle when medical personnel can be helped to sew up, it is to avoid inserting needle is excessively deep, cause the formation of dead space after sewing up, also avoid otch both sides depth of needle to differ and cause that engaging tissue degree is not enough.

Preferably, pin hole port of export week side is provided with the prompting portion of indicatrix tieing placement location. It is easy to threading.

Preferably, prompting portion is made up of fluorescent material. Can be more luminous in when light is more weak, it is simple to threading, the searching after being simultaneously conducive to suture needle to lose.

Compared with prior art, the advantage of this Medical needle is in that: reasonable in design, simple in construction, threading convenience and needlework are not easily disconnected from, owing to single line suturing skill can be adopted to significantly reduce the misery of patient, suture needle is provided with scale and improves sewing effect, the prompting portion that fluorescent material is made facilitates the searching after threading and suture needle loss, shortens suture time.
