Flap supporting structure of artificial cochlea implant

Abstract

The invention discloses a flap supporting structure of an artificial cochlea implant. The flap supporting structure comprises a flap drilling needle, a hollow bolt, a three-foot supporter and a fixednut; the hollow bolt comprises a main body, the main body comprises a cavity, the flap drilling needle is sleeved with the cavity, an outer thread is arranged at the outer periphery of the main body,and the head of the main body comprises a round supporting sheet; the three-foot supporter comprises three foot parts and a base plate, the upper surfaces of the three foot parts are connected with the base plate, the foot parts are arc, the base plate comprises a through hole, the outer diameter of the through hole is larger than that of the main body, the fixed nut is in threaded connection withthe hollow bolt, and the bottom face of the fixed nut abuts against the surface of the base plate. The flap supporting structure is reasonable in supporting structure and convenient to operate, fullyopens the skin, guarantees the operation field, protects the skin and prevents subcutaneous tissue injuries.

Description

technical field [0001] The invention relates to a cochlear implantation surgical instrument, in particular to a supporting structure for the cochlear implantation operation. Background technique [0002] Traditional cochlear implantation needs to open the mastoid and polish the bone groove on the surface of the skull behind the mastoid. Therefore, a large "S"-shaped incision will be made behind the ear, and then the scalp will be turned backward, resulting in a large trauma, and Increased chances of complications leading to scalp hematoma and necrosis. In recent years, the incision technique has been gradually improved, and the small incision behind the ear has greatly reduced the trauma, and no obvious complications of scalp hematoma and necrosis have occurred. Grinding the bone groove in the operating space is cumbersome. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a support structure that can increase th...
