Abstract

The invention relates to a double-cross-surface laser-directional minimally-invasive cranial drill which is a positioning perforating drill for taking out intracranial hematoma and is provided with a machine body, a driving mechanism and a bit, wherein the driving mechanism is arranged in the machine body, and the bit is connected with an output shaft of the driving mechanism in a coaxial way. The machine body is provided with two cross planar light lasers of which the intersecting lines are collinear with bit axes. Preferably, one planar light laser is fixed with the machine body, and the other planar light laser is wound with the bit axes of the machine body to be in transitional fit and rotating connection. Under the guidance of a three-dimensional benchmark determined by the surface of the head part, the head surface drawing lines of the layer surface of a hematoma center in each direction are calculated out according to data on a CT (computed tomography) photo and are overlapped with head surface cross drawing lines through cross planar light emitted by the lasers so as to imitate noninvasive quick and easy positioning and perforating performed by hematoma on different panels.

Description

Technical field: [0001] The invention is a medical instrument for minimally invasive removal of intracranial hematoma, which is an instrument for directional opening after determining the central position of the intracranial hematoma and the opening position of the head. Background technique: [0002] Minimally invasive hematoma puncture has been carried out in China for many years, but the curative effect of hematoma puncture is difficult to be objectively evaluated due to the influence of the operator's experience and technique. Previous cerebral hematoma punctures determined the central target point of the hematoma and the route into the cranium through the three-dimensional data of the patient's head CT or CT slice. Although the central target point of the hematoma could be determined by measuring the patient's head CT or CT, the head is A spheroid, with holes and punctures from the outside to the inside of the head, it is difficult to accurately puncture the target. Th...
