Description

Suture needle for nasal septum correction

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a suture needle for nasal septum correction.

Background

Nasal septum deflection refers to a disease of nasal cavity caused by nasal cavity dysfunction or symptoms due to deflection of the septum to one or both sides or local protrusion. When the nasal septum deflects and does not cause corresponding symptoms, the treatment can not be carried out, and when the patient has symptoms or physical signs which affect the quality of daily life, such as nasal obstruction, headache, epistaxis and the like, the operation treatment is needed. The most common surgical procedure at present is nasal endoscopic nasal septal correction. In the nasal septum rectification art process, need make the incision at the nasal septum of the convex side of deflection, separation nasal septum cartilage board and nasal mucosa, the convex sclerotin of part of shovel for the nasal septum is placed in the middle, then according to the operation condition, decides whether to close the nasal mucosa, sews up the incision, and common suture needle ware all is not fit for being applied to the sewing up of nasal septum mucosa incision in the present clinic. Because the nasal cavity itself is narrower, and the nasal endoscope needs to occupy certain space when sewing under the nasal endoscope, the space in the nasal cavity is narrower, the operation of the existing needle tool in clinic, such as angle needle, round needle and the like, needs certain space, and the operation of sewing the nasal septum incision is very inconvenient.

The common round needle in the prior art is not suitable for being applied to suture of nasal septum mucosa in a narrow nasal cavity; the angle needle has a certain bending compared with a round needle and is used for suturing the septum of a patient, but the bending angle of the needle body and the needle body is small, but the angle needle cannot meet the requirement of suturing the septum of the nose in a narrow nasal cavity.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a suture needle for nasal septum correction, which solves the above problems of the prior art.

In order to solve the above problems, the present invention provides the following technical solutions:

a nasal septum orthopedic suture needle comprises a needle body, a needle handle and an adhesive structure for connecting the needle body and the needle handle;

the needle body is divided into a bending section positioned at the front end of the needle body, a needle head arranged at the head part of the bending section and a needle body tail section connected with the bonding structure.

The nasal septum orthopedic suture needle provided by the utility model also has the following technical characteristics:

furthermore, the needle handle is provided with an anti-skid structure.

Furthermore, the length range of the needle body is 50-70mm, and the inner diameter size range of the needle body is 0.7-0.9 mm.

Furthermore, the bending angle range of the bending section is 140-160 degrees, and the length range of the bending section is 8-15 mm.
