Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 to Figure 5 As shown, a temporomandibular joint separation cap is composed of a separation cap head 4 and a fixed handle 5; the fixed handle 5 is arranged at the lower part of the separation cap head 4 and connected with the separation cap head 4, and the separation cap head 4 is opened downward The spherical groove structure or the elliptical spherical groove structure are uniformly provided with 1 to 6 screw fixing holes 6 on the fixing handle 5 .

[0024] The separation cap head 4 is a depth structure in which the groove structure is hemispherical, one-third spherical or one-quarter spherical. The screw fixing holes 6 on the fixing handle 5 are single row fixing holes or double row fixing holes, the diameter of the screw fixing holes 6 is 1.6-2.8mm, the screw fixing holes 6 on the fixing handle 5 can be connected wit...

Abstract

The invention discloses a temporomandibular joint separation cap and a fixing method thereof, which is composed of a separation cap head and a fixing handle; the fixing handle is arranged at the lower part of the separation cap head and connected with the separation cap head, and the separation cap head opens downward The spherical groove structure or the elliptical spherical groove structure are uniformly provided with 1 to 6 screw fixing holes on the fixing handle. The invention can effectively separate the temporal muscle joint fossa from the mandibular joint without amputating the mandibular joint head and mandibular bone tissue, has small surgical trauma, and is convenient for postoperative rehabilitation of patients. Since the thickness of the temporomandibular joint separation in the present invention is only 0.1 mm to 0.6 mm, it can effectively reduce the patient's discomfort, improve the stability of the occlusal relationship, overcome the need for permanent implantation of the temporomandibular joint in the prior art, and replace the original The condition of bone tissue. After the temporomandibular joint ankylosis is cured, it may be considered to remove the temporomandibular joint separation cap of the present invention, so as to effectively avoid permanent damage to the patient.

Description

technical field [0001] The invention belongs to the technical field of artificial joints, and in particular relates to a temporomandibular joint separation cap and a fixing method thereof. Background technique [0002] Temporomandibular joint ankylosis is a common and frequently-occurring disease of the maxillofacial region. Trauma to the maxillofacial region sometimes injures the temporomandibular joint, resulting in fractures of the articular process and neck of the articular process and contusion of tissues within the joint. If the recovery is not good, It can easily lead to ankylosis of the temporomandibular joint. Patients present with limited mouth opening and chewing, joint murmurs, occlusal disorder, and dysfunction. Most of the cases are accompanied by deformities caused by developmental disorders of the lower face, such as facial asymmetry and small jaw, which seriously affect the patient's chewing and language. and facial contours. [0003] Temporomandibular joi...
