Submandibular approach reduction forceps for fracture of temporal-mandibular joint

Abstract

The invention belongs to the technical field of oral medicine apparatuses, relates to a submandibular approach auxiliary operation apparatus for low and middle position fracture of the temporal-mandibular joint of the mandible, in particular to submandibular approach reduction forceps for fracture of the temporal-mandibular joint. The reduction forceps comprise reduction forcep bodies, a mandibleangle fixing device and a supporting device, the mandible angle fixing device comprises a locating support; a connecting column is arranged on the locating support, a rectangular through groove is further formed in the locating support and further provided with a clamping device. Compared with the prior art, the device has the advantages that the mouth of the forceps is set as a cambered surface triangle, high-temperature resistance rubber is utilized, and a plurality of contact points can be ensured in the clamping process; the stability of clamping is ensured, and clamping force is increased; the mandible angle fixing device and the reduction forceps are assembled together, and repeated displacement of fracture is prevented more effectively; assembling is simple, and the forceps can be used singly or used in a combination mode; the integral structure is simple and reasonable, using is convenient, it can be ensured that in the operation process, the forceps cannot be influenced by other apparatuses, and the forceps are easy to sterilize and suitable for using and polarization.

Description

technical field [0001] The invention belongs to the technical field of stomatology equipment, and relates to an auxiliary operation device for selecting a submandibular approach for low-median mandibular joint fractures in stomatology, in particular to a submandibular approach reduction forceps for temporomandibular joint fractures. Background technique [0002] Temporomandibular joint fractures are determined by their physiological structure. With the application of the submandibular approach, more and more people have found that this surgical approach can increase the surgical field of view and reduce the difficulty of operation. However, ordinary fracture forceps cannot effectively clamp The temporomandibular joint is clamped, and because the surrounding muscles are more attached, it often leads to the effective clamping of the temporomandibular joint, and the reduction is more difficult. At the same time, it is necessary to exert a certain force on the temporomandibular j...

[0002] Temporomandibular joint fractures are determined by their physiological structure. With the application of the submandibular approach, more and more people have found that this surgical approach can increase the surgical field of view and reduce the difficulty of operation. However, ordinary fracture forceps cannot effectively clamp The temporomandibular joint is clamped, and because the surrounding muscles are more attached, it often leads to the effective clamping of the temporomandibular joint, and the reduction is more difficult. At the same time, it is necessary to exert a certain force on the temporomandibular joint head before using the fractured titanium plate, so that the nail can be drilled out This often leads to the re-displacement of the newly aligned fracture line, so the current clamping method cannot effectively assist the operation, resulting in prolonged operation time and increased difficulty
