Skull perforator and skull perforating assembly

Abstract

The invention relates to a skull perforator and a skull perforating assembly. The skull perforating assembly comprises a connecting column and an outer ring saw. The connecting column is used for being connected with a rotating shaft of a motor. The outer ring saw is connected with the connecting column and comprises a base body and a cutting piece arranged in the circumferential direction of oneend face of the base body. The cutting piece is used for annular cutting to take out bones of the cut part. When a small-area hole is formed, the cutting piece of the outer ring saw carries out annular cutting treatment on the part, needing to be perforated, on the skull, after the part, needing to be perforated, on the skull is cut through, the bones of the cut part are moved away, an operation is carried out, and after the operation is finished, the bones of the cut part are put back to the perforated part of the skull. In this way, the part, needing to be perforated, on the skull is not traditionally drilled through in a smashing mode, instead, the bones of the cut part are taken out after annular cutting treatment is carried out on the perforated part, the bones of the cut part are putback to the perforated part after the operation is completed, in this way, operation wounds can be reduced, and the skull perforator and the skull perforating assembly are beneficial for recovery ofhealth of a patient.

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
