The medical suture needle is mainly used for surgical suture, is mostly made of stainless steel wires by drilling or grooving at the tail of the needle, and has polished appearance and electrolytic treatment, and is quite smooth; the needle type is divided into: round needle, angle needle, shovel needle, straight needle etc., the radian is divided into according to actual need: 1/2, 3/8, etc.; the production process is very complex, belongs to high-tech products, and even adopts the laser drilling technology for fine drilling. To date, medical needles have evolved in three generations: the first generation of traditional eye needles: like a curved sewing needle; a bullet machine hole needle, wherein a fork-shaped clamping groove is formed in the tail part of the bullet machine hole needle; the first generation was mainly used for non-absorbable sutures. Second generation, grooved needle: the tail part is grooved and connected by needle and line, and is mainly used for suturing parts with low requirements or thinner suture lines. Third generation, drilling needle: the tail is drilled and the needle and the line are connected, and the suture is mainly used for micro-wound suture.

After the tendon stopping point is stripped off in the prior orthopedic operation, the tendon is very difficult to be re-stitched back to the stopping point for anatomic reconstruction, and the novel orthopedic bone-penetrating and fixing tendon stopping point multifunctional operation stitching needle is designed, so that the problems can be easily solved, and time is saved.

Disclosure of Invention

The utility model aims to provide a surgical suture needle which is convenient to use and is beneficial to improving suture efficiency.

The utility model solves the problems by adopting the following technical scheme:

the utility model provides an operation suture needle, includes the needle body, be equipped with two unidirectional oblique forks that are bilateral symmetry setting on the one end of needle body, form V-arrangement guide way between two unidirectional oblique forks, the one end and the external space intercommunication of V-arrangement guide way, the other end and the wire casing intercommunication of V-arrangement guide way do benefit to the suture line and get into in the wire casing from V-arrangement guide way, be equipped with a plurality of winding pieces in the wire casing, the winding piece is parallel staggered arrangement, the through wires hole is located the below of wire casing, communicates through the recess between through the through wires hole and the wire casing, is equipped with the syringe needle on the opposite side of needle body.

As a further improvement of the technical scheme, the needle head adopts the triangular needle head or the round needle head, so that a user can select a sewing needle with a proper needle head to sew according to the strength of the sewing position, the sewing efficiency and quality are guaranteed, the sewing cost is controlled, and the application range of the sewing needle is improved.

As a further improvement of the technical scheme, the cross section of one end of the needle body is arc-edge rectangular, the cross section of the other end of the needle body is circular, the thickness difference is formed, the suture line is prevented from further expanding the channel of the suture needle penetrating through human tissues, the damage of the suture line to the human tissues is reduced, and the suture effect is guaranteed.

As a further improvement of the technical scheme, the needle body, the unidirectional bevel fork and the needle head are all made of stainless steel materials, so that the use safety is improved, and the damage to a human body caused by suturing when the suture needle is used due to rust is avoided.

As a further improvement of the technical scheme, the needle body is arc-shaped, so that the strength of pulling the suture position is reduced, and the suture needle can be conveniently penetrated from inside to outside during suture.

Compared with the prior art, the utility model has the following advantages and effects:

according to the utility model, through the cooperation of the wire slot, the threading hole and the winding sheet, one end of the suture thread passing through the threading hole can be fixed by winding on the winding sheet, so that the risk of suture thread detachment in the suture process is reduced, and the situation of repeated threading and exchanging of the needle holder in the suture process is avoided. Meanwhile, as the suture needle and the suture thread can be flexibly combined for use, a user can replace the suture needle or the suture thread according to the use requirement, and the suture needle is beneficial to the user to suture by adopting any suture methods such as single-side mattress type suture, horizontal mattress type suture, 8-shaped suture, intermittent suture, continuous suture, serging suture, double-line reinforced suture and the like, shortens the preparation time of a suture tool, improves the operation efficiency and ensures the suture effect. Further, through the setting of V-arrangement guide way, reduced the degree of difficulty that the suture got into the wire casing, improved the convenience of operation, do benefit to the fixed of suture, raise the efficiency.
