Skull Opener and Skull Opening Components

Abstract

The invention relates to a skull opening device and a skull opening assembly. The skull opening assembly includes a connecting post and an outer trephine. The connecting column is used to connect with the rotating shaft of the motor. The outer trephine is connected with the connecting column, and the outer trephine includes a seat body and a cutting member circumferentially arranged around one end face of the seat body. The cutting element is used for circular cutting to remove the bone at the resection site. When opening small-area holes, the cutting part of the outer trephine performs a circumcision on the part of the skull that needs to be drilled. Surgery, after surgery, the removed bone is put back into the opening of the skull. In this way, instead of drilling through the part of the skull that needs to be opened by comminution, as traditionally, the part of the opening is circumcised and then the bone of the excised part is taken out, and then the bone of the excised part is put back into the opening after the operation is completed. The location of the hole can reduce the surgical trauma and is beneficial to the patient's recovery.

Description

technical field [0001] The invention relates to the technical field of skull surgery tools, in particular to a skull hole opener and a skull hole opener assembly. Background technique [0002] Craniotomes are used to drill holes in the skull during neurosurgery. The openings on the skull are divided into large-area holes and small-area holes according to the size of the holes. Here, the small-area hole refers to a hole whose diameter is, for example, within 25 mm. The traditional method of drilling large-area holes is to first open several small-area holes on the skull, and then use a milling cutter to mill out several strip-shaped openings on the skull. The strip-shaped openings connect the several small-area holes to each other. This creates a large hole in the skull. However, for the opening of small-area holes, since the milling cutter cannot be used to cut and form the skull, usually the drill bit of the skull opener is used to completely drill through the skull area...

Problems solved by technology

However, for the opening of small-area holes, since the milling cutter cannot be used to cut and form the skull, usually the drill bit of the skull opener is used to completely drill through the skull area corresponding to the small-area hole, so that the trauma to the skull Larger, a craniotomy will be left after surgery, and the patient's recovery will be slower
