Mandibular condylar process detecting hook

Abstract

The invention relates to the field of medical apparatus and instruments and particularly relates to a mandibular condylar process detecting hook comprising a handle and a detecting hook fixedly arranged at the end of the handle; the detecting hook sequentially comprises a first detecting hook section, a second detecting hook section and a third detecting hook section from bottom to top; the included angle between the first detecting hook section and the second detecting hook section is 140-160 DEG, and the included angle between the second detecting hook section and the third detecting hook section is 140-160 DEG; the third detecting hook section is provided with a pointed cone, and the included angle between the pointed cone and the third detecting hook section is 110-120 DEG; the handle is of a cylinder and is 8-15 CM long; the first detecting hook section is 5-8 CM long; the second detecting hook section is 5-8 CM long; the third detecting hook section is 1-3 CM long; and the pointed cone is 0.5-1.5 CM long. The device is provided with a position display device, so that the position of the detecting hook can be clearly displayed under an environment with a poor visual condition.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a probing hook for mandibular condyle. Background technique [0002] The posterior upper end of the mandible is the condyle, the upper end of the condyle expands into the condyle head, and the condyle head and the mandibular fossa of the temporal bone form the temporomandibular joint. The mandibular condyle is located at the caudal end of the temporal bone. After the mandibular condyle is fractured, the mandible loses its joint fulcrum, and there is more muscle tissue on the mandible. The femoral fracture block is blocked inside the muscle. In this case, it is necessary to open the patient's face, pull the mandible and find the condylar bone fragment, and then fix the condylar bone fragment with the mandible; while the existing The probe hook is usually straight, which is not conducive to exploring the condylar bone fragments in the narrow and complicated opening, and the visi...

Problems solved by technology

The mandibular condyle is located at the caudal end of the temporal bone. After the mandibular condyle is fractured, the mandible loses its joint fulcrum, and there is more muscle tissue on the mandible. In this case, the muscles will pull the mandible, and the condyle The femoral fracture block is blocked inside the muscle. In this case, it is necessary to open the patient's face, pull the mandible and find the condylar bone fragment, and then fix the condylar bone fragment with the mandible; while the existing The probe hook is usually straight, which is not conducive to exploring the condylar bone fragments in the narrow and complicated opening, and the visibility in the opening is not very good, and the end of the probe hook is hook-shaped or sharp. It will inevitably cause damage to tissues such as muscles or nerves in the opening
