Abstract

The invention discloses a positioner for an intracranial operation. The positioner comprises a fixing arm, a transverse adjusting arm, a longitudinal positioning arm, a longitudinal positioning nail,a transverse positioning nail, an auxiliary positioning nail and an auxiliary operation mechanism. The fixing arm is equipped with a horizontal transverse part and a vertical longitudinal part. The longitudinal positioning nail can be arranged at the left end of the transverse part in an adjustable manner. The longitudinal positioning nail can be positioned at the top of an external skull. The longitudinal positioning arm is arranged at the lower end of the longitudinal part along the direction being parallel to the longitudinal part in a position-adjustable manner. The transverse positioningnail is arranged at the lower end of the longitudinal positioning arm in a position-adjustable manner along the direction being parallel to the transverse part. The transverse positioning nail can bepositioned on one side part of the skull. The transverse adjusting arm is arranged on the transverse part along the direction being parallel to the transverse part in a position-adjustable manner. Theauxiliary positioning nail and the auxiliary operation mechanism can be arranged on the transverse adjusting arm in the mutually detaching and replacing manner. The auxiliary positioning nail can bepositioned on the other side part, departing from the transverse positioning nail, of the skull. The auxiliary operation mechanism can be used for assisting an intracranial surgery operation.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a positioning device for intracranial surgery. Background technique

[0002] Hypertensive intracerebral hemorrhage (HICH) is a common severe neurosurgical disease with a high mortality rate. There are many surgical methods for hypertensive cerebral hemorrhage. Different surgical methods are determined according to the bleeding site, bleeding volume, age, bleeding speed, time, underlying disease conditions, and local hospital conditions. The common surgical methods are:

[0003] 1. Minimally invasive puncture and drainage: In terms of minimally invasive puncture and drainage for the treatment of HICH, there are hard channel puncture and drainage techniques (such as YL-1 puncture needle) and soft channel puncture and drainage techniques in China.

[0004] 2. Large bone flap craniotomy for hematoma removal and decompression: for patients with a large amount of bleeding ...
