Problems solved by technology

However, there is currently no periosteal stripper specially used for the lower and posterior border of the mandible. The traditional straight-handled stripper is limited by the operating angle during the intraoral approach, so it cannot fit the special shape of the mandible, and there are many shortcomings: such as It is not suitable for the peeling of the lower and posterior edges of the mandible by intraoral reflexion, and it is not suitable for the operation of plastic surgeons, nor can it be well explored for the degree of peeling of the lower and posterior edges of the mandible, and it is easy to cause residues during the operation. tissue damage

Abstract

The invention discloses a mandible inferior border posterior border elevator. The elevator comprises a strip connecting part, as well as a handheld part and an operating head which are fixedly connected with the two ends of the connecting part, wherein the operating head adopts a bent structure; a knife-edge structure with an arc transition surface on the outer side is arranged at the tip part of the operating head. The elevator adopts an anatomical shape which can be perfectly adhered to mandible, ensures that decollement operation is convenient, is suitable for the operation of an orthopedist, can properly peel mandible inferior border and posterior border, and greatly reduce residual tissue damage of a patient during operation.

Description

technical field [0001] The invention relates to the field of mandibular surgical instruments, in particular to a stripper for stripping the lower edge and the rear edge of the mandible in mandibular angle osteotomy and plastic surgery. Background technique [0002] Mandibular angle osteotomy is a common plastic surgery procedure used to improve the appearance of a square face caused by large subfacial bones. During the mandibular angle osteotomy, since there are many muscular tissues and ligaments attached to the surface of the mandible, it is very easy to injure and bleed when the bone segment is cut, which will affect the operation and cause unnecessary tissue trauma to the patient. Therefore, before the mandibular angle osteotomy, the operator often needs to use a dissector to separate the lower and posterior edges of the mandible from the surrounding soft tissues. However, there is currently no periosteal stripper specially used for the lower and posterior border of the...
