Abstract
The invention relates to an intracutaneous tissue anastomat and a preparation method thereof, in particular to an intracutaneous tissue anastomat made of titanium nickel memory alloy wires and a preparation method of the intracutaneous tissue anastomat. By the aid of the good biocompatibility and the good shape memory function of a shape alloy material and a superelasticity performance that the titanium nickel memory alloy intracutaneous tissue anastomat can linearly deform at the temperature of a human body, a perfect tissue anastomosis effect can be achieved during surgery.
Description
Technical field
The present invention relates to a kind of medical Intradermal and organize anastomat, particularly a kind of Intradermal of making as raw material with the ti-ni shape memory alloy silk is organized anastomat.
Background technology
At present, the Intradermal tissue that uses clinically is identical to be with the nylon yarn material.Because after using nylon yarn, the tension force of nylon yarn also disappears in the process that the skin histology edema disappears thereupon, cause skin incision healing back cicatrix obvious especially, bring unnecessary trouble and misery to patient.In addition, be difficult to be connected between the very thin silk of diameter and the metal sewing needle, caused the phenomenon of in operation process, falling pin, broken string, also limited the promotion and application that intradermic suture is performed the operation.
Summary of the invention
In order to overcome the identical many unfavorable factors clinically of existing Intradermal tissue, the present invention proposes a kind of Intradermal of making as raw material with the ti-ni shape memory alloy silk and organizes anastomat and preparation method thereof.
Technical solution of the present invention is:
A kind of ti-ni shape memory alloy Intradermal is organized anastomat, comprises stitching thread, and its special character is: it also comprises the medical suture needle that is connected mutually with stitching thread one end, and shape memory was collinear ti-ni shape memory alloy silk when said stitching thread was 27～33 ℃; The end face of the non-operative end of said medical suture needle is provided with blind hole; Be projecting end with a end that medical suture needle is connected mutually on the said stitching thread; The somewhat larger in diameter of said projecting end is slightly less than the diameter of blind hole in sutural diameter, said projecting end is fixed in the blind hole.
Be connected through the blind hole stage casing mode of texturing of caving between the above projecting end and the blind hole.
Be connected through notch distortion and welding manner in the blind hole stage casing between above-mentioned projecting end and the blind hole.
Above-mentioned medical suture needle is triangle half looper.
The ti-ni shape memory alloy Intradermal is organized the method for preparing of anastomat, and it may further comprise the steps:
1] prepares ti-ni shape memory alloy silk and medical suture needle;
2] end at the ti-ni shape memory alloy silk is provided with projecting end, at the non-operative end end face drilling blind hole of medical suture needle; The somewhat larger in diameter of requirement projecting end is slightly less than the diameter of blind hole in sutural diameter;
3] projecting end of ti-ni shape memory alloy silk is put into blind hole, exert pressure to axis direction by lateral surface from the blind hole stage casing, block until the distortion of blind hole stage casing and with projecting end with instrument;
It also comprises the welding step after projecting end is blocked in the distortion of blind hole stage casing:
When with instrument from the blind hole stage casing by lateral surface to axis direction exert pressure block until blind hole stage casing distortion and with projecting end after, at the opening part of blind hole with medical suture needle and stitching thread firm welding.
Above-mentioned stitching thread be 27～33 ℃ constantly shape memory be collinear ti-ni shape memory alloy silk.
Advantage of the present invention is:
1, the present invention utilizes the memory alloy wire excellent biological compatibility; With shape memory function near the superelastic properties that produces the straight line distortion under the human body temperature; Adopt mechanical connection manner that medical suture needle firmly is connected with stitching thread; Direct stitching when skin histology coincide in being convenient to perform the operation is used, and seamed is cut off sutural end and medical suture needle with scissors together, thereby has saved operating time.
2, the present invention puts into the projecting end of ti-ni shape memory alloy silk the non-operative end end face blind hole of medical suture needle; With blind hole sidewall mode of texturing projecting end is blocked; Again from the blind hole opening part with stitching thread and medical suture needle firm welding; Avoid existing stitching thread to be connected unstable shortcoming with medical suture needle, guaranteed the safety of operation process.

The specific embodiment
Ti-ni shape memory alloy of the present invention is organized anastomat, comprise stitching thread, with the medical suture needle that stitching thread one end is connected mutually, shape memory was collinear ti-ni shape memory alloy silk when stitching thread was 27～33 ℃, medical suture needle is triangle half looper; The end face of the non-operative end of medical suture needle bores the blind hole that certain depth is arranged; An end that on stitching thread, is connected mutually with medical suture needle is provided with a projecting end through welding manner; Require the somewhat larger in diameter of this projecting end to be slightly less than the diameter of blind hole in sutural diameter; This projecting end is fixed in the blind hole, thereby guarantees that stitching thread and medical suture needle are connected.
The concrete steps that stitching thread and medical suture needle are connected are following: the projecting end of ti-ni shape memory alloy silk is put into blind hole; Require projecting end to withstand the inner face of blind hole; With fastening means the blind hole stage casing slowly and is evenly rotated the notch distortion and projecting end blocked of exerting pressure in the blind hole stage casing by lateral surface to axis direction, then stitching thread and medical suture needle are connected.In order to prevent that sutural projecting end from coming off from blind hole, also can with welding manner stitching thread and medical suture needle be welded by the blind hole opening part after being connected.
