Embodiment 1

[0021] Such as Figure 1-2 As shown, the suture needle for temporomandibular arthroscopy according to the embodiment of the present invention includes a needle body 1, a needle tube 2 is arranged at the top end of the needle body 1, a needle head 3 is arranged at the top end of the needle tube 2, and the needle body 1 One end of the needle tube 2 is provided with a grip part 4, and the end of the needle tube 2 away from the needle head 3 is inserted to the middle side of the grip part 4, the inner hole of the needle tube 2 and the grip part 4 The inner holes are connected, and the surface of the gripping part 4 is provided with anilox knurling 5 .

[0022] The specific setting and function of the needle body 1, the needle tube 2, the needle head 3, the grip part 4 and the anilox knurling 5 will be described in detail below.

[0023] Such as Figure 1-2 As shown, the length of the 3 parts of the needle is appropriate and the texture is hard, suitable for penetrating the tough...

Embodiment 2

[0025] Such as Figure 1-2 As shown, the needle 3 and the needle tube 2 are integrally connected. The needle 3 is tapered, and the needle 3 is 6 cm. .

[0026] Such as Figure 1-2 As shown, the handle 4 is connected to the interior of the needle 3 in a funnel shape. One end of the handle portion 4 located at the needle tube 2 is tapered. The tail end of the holding part 4 is connected with a three-way pipe.

[0027] In order to facilitate the understanding of the above-mentioned technical solution of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0028] In practical application, the length of the 3 parts of the needle is suitable and the texture is hard, suitable for penetrating the tough articular disc in the narrow joint cavity. Tough articular disc, the surface of the grip part 4 is knurled, which increases the friction force and facilitates the grip. The tail end of th...

Abstract

The invention discloses a temporomandibular arthroscope lower suture needle which comprises a needle body. A needle tube is arranged at the top end of the needle body, and a syringe needle is arranged at the top end of the needle tube; one end of the needle body is provided with a holding part, and the end, away from the syringe needle, of the needle tube is inserted into one side of the middle of the holding part; an inner hole of the needle tube is connected with an inner hole of the holding part, and a reticulate pattern knurling is arranged on the surface of the holding part. The suture needle has the advantages that the suture needle is applied to a temporomandibular arthroscope disc reduction operation, and can be matched with a puncture suture needle, a suture line is guided to penetrate through an articular disc and is fixed below the cartilage of the external auditory canal, and therefore reduction of the articular disc is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a suture needle under temporomandibular arthroscopy. Background technique [0002] The temporomandibular joint is composed of the joint formed by the temporal bone and the mandible and the masticatory muscles attached to the mandible. It is a bilateral linkage joint with the most complex structure and the most physiological functions among all joints in the human body. At present, the suture needle used in temporomandibular arthroscopic surgery is a non-disposable 12-gauge injection puncture needle, which can accommodate the passage of suture and cooperate with the puncture stapler to complete the suture and fixation of the articular disc. The length of the needle is too long, and the joint The operating space of the cavity is small, and the too long needle increases the difficulty of changing the angle of the suture needle. During the process of suturing and fixing the joint d...
