Abstract

The invention relates to a surgical instrument fixing device comprising a base, a horizontal rotating part, a vertical rotating part and a clamping part which are successively connected, wherein the clamping part comprises a V-shaped block and a wedge block; the V-shaped block and the wedge block are both arranged on the vertical rotating part; and the V-shaped groove of the V-shaped block corresponds to the slope of the wedge block. According to the surgical instrument fixing device, a navigation robot body and a pilot sleeve can be effectively isolated so as to satisfy the requirement on the precision positioning of the pilot sleeve.

Description

technical field [0001] The invention relates to a medical surgical instrument, in particular to a surgical instrument fixing device capable of fixing a guide sleeve in a surgical navigation system. Background technique [0002] The most commonly used surgical navigation system is the orthopedic minimally invasive surgery where the guide pin is inserted into the affected limb. The guide sleeve is needed to determine the position and direction of the guide pin, that is, the guide sleeve is positioned by the surgical navigation robot, and then the The doctor inserts the guide wire through the inside of the guide sleeve and eventually into the affected limb. According to the principle of surgical navigation robot positioning, it is required that the guide sleeve and the surgical navigation robot body must be connected by a universal joint device, and the universal joint device is used as a device for fixing the guide sleeve. This connection has the requirement of positioning acc...
