Description
Technical field
This utility model belongs to technical field of medical instrument, is specifically related to a kind of no threading sewing needle.
Background technology
The operation sewing needle small volume used at present, structure be simple, use also more for convenience, but due to sewing needle be silver color, close with floor color, volume is little, is difficult to differentiate, if sewing needle drops on floor, find very inconvenient, can only find again after end to be stapled.
Mainly carry out puncture with needle forceps folder sewing needle clinically at present to sew up, and existing sewing needle smooth surface, be easy to rotate in clamp process, add great work difficulty to medical worker, and clamp sewing needle is easy to make needle body rough surface, thus cause wound healing slow.
The operation sewing needle used at present is due to large ting model difference, and pin hole is also different, thick stitching thread can occur when threading a needle and wear to enter little stitching holes, or thin stitching thread skids off large stitching holes; And the time of threading a needle is long, the speed of impact operation, after sewing needle used clinically at present penetrates stitching thread, makes puncture needle eye larger because surface cushion adds stitching thread, also increases, add great work difficulty to medical worker to the infringement of human body.
Therefore, be necessary to make improvement to existing sewing needle, design a kind ofly can be convenient to find, effectively fixing, Quick-threading and not easily slippage and reduce the sewing needle of pinprick, reduce the damage that patient is subject to when sewing up, accelerate the healing rate of patient wound, be convenient to doctor simultaneously and find.
Summary of the invention
For problems of the prior art, this utility model provides a kind of no threading sewing needle, change needle body cross section into rectangular configuration, reflection groove is offered on sewing needle needle body surface, and reflecting surface is set in groove inside, reflecting surface direction random arrangement in reflection groove, when sewing needle drops, utilize diffuse reflection principle, sewing needle can be found fast, pin is provided with thin square tongs jig arm, doctor effectively can fix sewing needle, sewing needle is avoided to rotate in clamp process, and be provided with " W " type path and wire casing at backshank, stitching thread snaps in wire casing after " W " type path, after inflection returning line, returning line sticks into needle holder fixing rear use suitable for reading, can Quick-threading and not easily slippage and reduce pinprick, simultaneously, this utility model technique is simple, with low cost, easy to operate, practical.
For achieving the above object, this utility model provides following technical scheme: a kind of no threading sewing needle, and described no threading sewing needle comprises needle point, needle body, reflecting surface, reflection groove, thin square tongs jig arm, backshank, " W " type path and wire casing; Described needle body cross section is rectangular configuration, the rib of needle body is circular arc chamfering, needle body one end is connected with needle point, the other end is connected with thin square tongs jig arm, the larger plane in needle body both sides is provided with reflection groove, reflection groove inside is provided with reflecting surface, and thin square tongs jig arm is connected with backshank away from one end of reflection groove, is provided with " W " type path and wire casing in backshank.
As preferably, the edges and corners between adjacent two reflectings surface of described reflection groove inside are circular arc chamfering.
As preferably, the rib of described thin square tongs jig arm is circular arc chamfering.
As preferably, the quantity of described reflecting surface is more than one.
As preferably, the reflecting surface direction random arrangement in described reflection groove.
The beneficial effects of the utility model: change sewing needle needle body cross section into rectangular configuration, reflection groove is offered on sewing needle needle body surface, and reflecting surface is set in groove inside, reflecting surface direction random arrangement in reflection groove, when sewing needle drops, utilize diffuse reflection principle, sewing needle can be found fast, pin is provided with thin square tongs jig arm, doctor effectively can fix sewing needle, sewing needle is avoided to rotate in clamp process, and be provided with " W " type path and wire casing at backshank, stitching thread snaps in wire casing after " W " type path, after inflection returning line, returning line sticks into needle holder fixing rear use suitable for reading, can Quick-threading and not easily slippage and reduce pinprick, simultaneously, this utility model technique is simple, with low cost, easy to operate, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model no threading sewing needle.
In figure: the thin square tongs jig arm of 1-needle point, 2-needle body, 3-reflecting surface, 4-reflection groove, 5-, 6-backshank, 7-" W " type path, 8-wire casing.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to facilitate the technical staff to understand.
