Degree measuring instrument for craniocerebral keyhole surgery

Abstract

The invention relates to a surgery assistant device, in particular to a degree measuring instrument for a craniocerebral keyhole surgery, which solves the problems of incapability of precisely controlling a drainage tube placing angle and influences on surgery effects in the conventional cerebral hemorrhage keyhole surgery. The degree measuring instrument comprises a pedestal, wherein a positioning bracket is fixed on the pedestal; a positioning pin is arranged on the positioning bracket; a semicircular angle scale is arranged on the positioning bracket and can rotate by taking the positioning pin as a circle center; a gravity hammer chain is hung at a circle center of the angle scale; the tail end of the gravity hammer chain is connected with a gravity indication cone; the pedestal is horizontal or has a curved shape which is coincided with the craniocerebral radian of a human body; a level gauge is arranged on the pedestal; the angle scale has a hollow fence type structure; the gravity hammer chain and the gravity indication cone are positioned in the angle scale; and a guide groove is formed on the angle scale along a side cross section of a straight-line segment of the angle scale. The degree measuring instrument has a simple structure and is skillful in design and easy and convenient to operate, the inserting angle of a drainage tube is precisely controlled by using the degree measuring instrument, the aim of accurately cleaning bipolar hematoma is fulfilled, and the effects of draining and cleaning of the craniocerebral keyhole surgery are ensured.

Description

technical field [0001] The invention relates to an operation aid, in particular to a measuring instrument for minimally invasive craniocerebral surgery. Background technique [0002] It is well known that the appearance of cerebral hemorrhage is usually oval due to the relationship between the nerve projection fibers. In order to minimize the trauma / benefit ratio of minimally invasive debridement of cerebral hemorrhage, it is necessary to achieve one hole and multiple angles for debridement and drainage on the brain entity. design. Specifically in the actual operation, usually after CT scan and CTA examination, under the guidance of CT, choose to avoid the larger blood vessels and directly locate, and then perform skull drilling and drainage. After the hole is drilled, the position of the drainage tube is adjusted. It is very critical, especially when placing the drainage tube to the two poles of the ellipse, the angle control is the most critical, otherwise it will cause u...
