Auxiliary drill for craniotomy

Abstract

The invention relates to an auxiliary drill for craniotomy. During craniotomy, a plurality of fixing devices (including an anchoring ring which is contacted with the skull and an electrode cap which covers the anchoring ring) are needed so as to fix an electrode, a wire or a pipe which is connected from the inside of the skull to the outside of the skull, a traditional method is characterized in that the fixing devices are protruded out of the skull, so that projection is caused, accordingly, the condition that the electrode, the wire or the pipe is exposed to the outside due to skin damage which is easily caused, and the skin is also easily injured. With the auxiliary drill, the projection amplitudes of the fixing devices are reduced or the fixing devices are parallel to the skull or are lower than the plane of the skull, the probability of the skin damage which is caused by the fixing devices is lowered, the electrode, the wire or the pipe and the skin can be better protected, the danger of changing the electrode, the wire or the pipe which is caused by skin damage infection is reduced, and accordingly, the pain and economic loads of patients can be better relieved.

Description

technical field [0001] The invention belongs to medical equipment, in particular to an auxiliary drill for craniotomy. After the craniotomy drill penetrates the skull, a circular groove can be drilled around the bone hole to place a fixing device. Background technique [0002] In craniotomy, some fixation devices (such as anchor rings in contact with the skull and electrode caps covering the anchor rings) are often needed to fix the electrodes, wires or catheters connected from the intracranial to the extracranial. Cranial drill, whether it is a hand-operated drill or an electric drill, the diameter of the drilled skull is the same as the length of the upper and lower sides of the skull, so that these fixing devices protrude outside the skull and make the place bulge, which easily causes skin damage and leads to exposure of electrodes, wires or catheters. Easy to cause skin trauma. Contents of the invention [0003] The object of the present invention is in order to overc...
