Abstract
A kind of micro-vascular surgery identical top operation sewing needle and manufacture method thereof of being used in.Operation sewing needle is made with molybdenum or cobalt molybdenum alloy silk.Method is the afterbody tubing at pin, and the crooked chinlon line in back of will finalizing the design then, heat is put into pipe and carried out drawing with needle system.The chinlon line is fixed in the needle body.Solved the problem that does not manufacture the little operation sewing needle of diameter that causes owing to original material extension poor performance and manufacture method thereof like this, and can not be presented in the problem in the visual field because the suture of pin is straight line suture when operation.The present invention can be applied in above the microsurgical vascular anastomosis.
Description
The present invention is a kind of micro-vascular surgery identical top operation sewing needle and manufacture method thereof of being used in.
Generally be used in micro-vascular surgery and coincide top operation sewing needle by the stainless steel silk manufacturing, suture is deformable textile materials such as straight shape chinlon line.Method is that the metal bit with small dimension bores an alignment hole on needle handle, with the method for pressing mold or with cover textile material is anchored in the alignment hole then.Said sewing needle is made by rustless steel in " effect and the evaluation thereof of micro suture in microvascular surgery " article in " reproducing microsurgery " book of U.S.'s publication in 1977, and the diameter minimum is 50 microns.Owing to adopt said method and, can not produce the again little sewing needle of diameter because of stainless extension poor performance; At 1975 3,910, the manufacture method of the sewing needle described in No. 282 United States Patent (USP)s " ultimate fibre sewing needle " also is then stitching thread to be embedded between the alignment hole of pin rear end with bit bore in needle handle portion, press solidly in the alignment hole with stamping method, can only reach 800 microns with the sewing needle diameter minimum of this kind method manufacturing.Make sewing needle with said method, the technology more complicated, and it is highly difficult big to bore dark and little hole cost on the needle handle.Can not produce diameter less than 50 microns sewing needle.Because diameter is big and bigger to the blood vessel injury degree, blood capillary aspect success rate of operation is only about 80%.And, be straight shape textile material because existing sewing needle adopts, harder and integral body line of filament can not be presented in again within the visual field of microscopically, is difficult for finding the end of a thread when knotting, so be unfavorable for operation.
The objective of the invention is to adopt new material, produce the littler operation sewing needle of diameter with more advanced more simple method in order to replenish the not enough of the said goods and to improve complicated processing technique.Improve success rate of operation with this sewing needle, reduce degree of injury, enlarge medical range the microsurgery microvascular anastomosis to blood vessel.
The operation sewing needle of a bending of accompanying drawing one expression.The single line body is the Serpentis sigmoid, and the suture that the line tail is the bending of " N " shape is fixed in the pin.A is the cross-sectional view of pin diameter among the figure, and 4 is needle body, and 5 is the line body, and 6 is the line tail.
Accompanying drawing two expression be that whole sewing needle is presented in the figure within the field of microscope in the operation, 1 is the microscope illumination radius among the figure, 2 is radius of view, 3 is sutural axle center, axle center 3 is less than radius of view 2.
Accompanying drawing three is a suture moulding manuscript, and 7 for being fixed on the metal bar on the chassis among the figure.8 is the chassis, and 9 is the heat drying case.
Accompanying drawing four is the tubing manuscript.10 is the tubing device among the figure, and 11 is the bellmouth of tubing device.
Accompanying drawing five is the anchor suture manuscript.12 is the anchor suture device among the figure, and 13 is the anchor suture bellmouth.
Operation sewing needle as shown in Figures 1 and 2, it is formed by the made needle body 4 of molybdenum or cobalt molybdenum alloy silk with chinlon line 5, and wherein an end of chinlon line 5 is fixed on the end of needle body 4, and one end 6 is a free end, it is crooked to be the little degree of " N " shape, and whole chinlon line 5 is the Serpentis sigmoid.Its manufacture method is that the end cold forging draw down at molybdenum or cobalt molybdenum alloy silk 4 makes it to broaden, the bellmouth 11 that the other end of molybdenum or cobalt molybdenum alloy silk 4 is passed the tubing device carries out drawing then, make the position that broadens pull out into the pipe shape, then pipe is put in the termination of the chinlon line body 5 of bending, again molybdenum or cobalt molybdenum alloy silk 4 are carried out drawing in the bellmouth 13 by the littler anchor suture of diameter, suture is pressed in the pipe.The manufacture method of curve is that chinlon line body 5 is come and gone around 7 tensions of several metal bars, is placed on then in the heat drying case 9 and heats.Adopt this material and manufacture method, it is good to produce quality, and diameter is little, the sewing needle of being convenient to operate.This pin is little to the blood vessel injury degree in operation process.And because line is made Serpentis sigmoid shape, shortened 3～4 times of the length (physical length does not reduce) of suture, line profile width is increased, be convenient under the narrow and small operating microscope visual field, seek line body, line tail, helped knotting; And afterbody is the drawback that the bending of " N " shape can avoid passing completely through easily owing to straight line is sliding tissue.Thereby having improved success rate of operation, the needle point of pin front end can be processed into needed shape with the method sharpening that passes through example.Suture also can adopt other deformable textile material.
Product needle body of the present invention is straight through reaching 30 microns, and it is fixed that the diameter of needle system and tubing device will come according to the diameter of pin; The temperature of processing crooked chinlon line is between 150 ℃～240 ℃, and warm-up time is between 2～10 hours.
The inventive method is simple, and material extension performance is strong, and it is little to produce diameter, the sewing needle that intensity is high.This kind sewing needle diameter is little, and line is bending and is convenient to operation, can improve success rate of operation, can be applied on the microsurgical vascular anastomosis.
Claims (5)
1, the operation sewing needle that is made by metal and chinlon line is characterized in that sewing needle made by molybdenum or cobalt molybdenum alloy silk, and the I of needle body diameter reaches 30 microns.
2, operation sewing needle as claimed in claim 1 is characterized in that the line body of described chinlon line is the Serpentis sigmoid.
3, operation sewing needle as claimed in claim 2 is characterized in that the line tail of said chinlon line is the little degree bending of " N " shape.
