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 tissue anastomat, particularly the intradermal tissue anastomat that makes as raw material of a kind of titanium-nickel memory alloy wires.
Background technology
At present, it is make of nylon yarn material that the intradermal tissue used clinically coincide.After using nylon yarn, in the process that skin histology edema disappears, the tension force of nylon yarn also disappears thereupon, and after causing skin incision closure, cicatrix is obvious especially, brings unnecessary trouble and misery to patient.In addition, the silk that diameter is very thin is difficult to be connected with between metal suture pin, causes the phenomenon falling pin, broken string in operation process, also limit the promotion and application of intradermic suture operation.
Summary of the invention
In order to overcome many unfavorable factors that existing intradermal tissue coincide clinically, the present invention proposes intradermal tissue anastomat that a kind of titanium-nickel memory alloy wires makes as raw material and preparation method thereof.
Technical solution of the present invention is:
A kind of nickel-Titanium memory alloy intradermal tissue anastomat, comprise stitching thread, its special character is: it also comprises the medical suture needle be connected mutually with stitching thread one end, and when described stitching thread is 27 ~ 33 DEG C, shape memory is the titanium-nickel memory alloy wires of straight line; The end face of the non-operative end of described medical suture needle is provided with blind hole, one end that described stitching thread is connected mutually with medical suture needle is projecting end, the diameter of described projecting end is slightly less than the diameter of blind hole slightly larger than sutural diameter, described projecting end is fixed in blind hole.
Upper to be connected by blind hole stage casing mode of texturing of caving between described projecting end and blind hole.
Be connected by notch distortion and welding manner in blind hole stage casing between above-mentioned projecting end and blind hole.
Above-mentioned medical suture needle is triangle half looper.
The preparation method of nickel-Titanium memory alloy intradermal tissue anastomat, it comprises the following steps:
1] titanium-nickel memory alloy wires and medical suture needle is prepared;
2] projecting end is set in one end of titanium-nickel memory alloy wires, at the non-operative end end face drilling blind hole of medical suture needle; Require that the diameter of projecting end is slightly less than the diameter of blind hole slightly larger than sutural diameter;
3] projecting end of titanium-nickel memory alloy wires is put into blind hole, exerted pressure to axis direction by lateral surface from blind hole stage casing with instrument, until blind hole stage casing is out of shape and is blocked by projecting end;
It also comprises blind hole stage casing and is out of shape the welding step after blocking projecting end:
When being exerted pressure to axis direction by lateral surface from blind hole stage casing with instrument until blind hole stage casing distortion and after projecting end is blocked, at the opening part of blind hole by medical suture needle and stitching thread firm welding.
Above-mentioned stitching thread be 27 ~ 33 DEG C constantly shape memory be the titanium-nickel memory alloy wires of straight line.
Advantage of the present invention is:
1, the present invention's biocompatibility of utilizing memory alloy wire good, with shape memory function close to produce under human body temperature straight line distortion superelastic properties, mechanical connection manner is adopted firmly to be connected with stitching thread by medical suture needle, the direct stitching be convenient to when skin histology coincide in performing the operation uses, sew up complete scissors sutural end is cut off together with medical suture needle, thus save operating time.
2, the projecting end of titanium-nickel memory alloy wires is put into the non-operative end end face blind hole of medical suture needle by the present invention, by blind hole wall deformation mode, projecting end is blocked, again from blind hole opening part by stitching thread and medical suture needle firm welding, avoid existing stitching thread and be connected unstable shortcoming with medical suture needle, ensure that the safety of operation process.

Detailed description of the invention
Ti-ni shape memory alloy tissue anastomat of the present invention, the medical suture needle comprising stitching thread, be connected mutually with stitching thread one end, when stitching thread is 27 ~ 33 DEG C, shape memory is the titanium-nickel memory alloy wires of straight line, and medical suture needle is triangle half looper; The end face of the non-operative end of medical suture needle bores the blind hole that has certain depth, one end that stitching thread is connected mutually with medical suture needle arranges a projecting end by welding manner, require that the diameter of this projecting end is slightly less than the diameter of blind hole slightly larger than sutural diameter, this projecting end is fixed in blind hole, thus ensures that stitching thread and medical suture needle are connected.
The concrete steps that stitching thread and medical suture needle are connected are as follows: the projecting end of titanium-nickel memory alloy wires is put into blind hole, require that projecting end withstands the inner face of blind hole, with fastening means by blind hole stage casing by lateral surface to axis direction slowly and uniform rotation is exerted pressure until notch distortion and being blocked by projecting end in blind hole stage casing, then stitching thread and medical suture needle are connected.In order to prevent sutural projecting end from coming off from blind hole, also can stitching thread and medical suture needle be welded the blind hole opening part welding manner after being connected.
