Abstract

The invention relates to detachable-mountable arc-shaped precise positioning equipment, which includes a supporting unit, a three-dimensional regulating unit connected to the supporting unit, and a guidance positioning unit. The guidance positioning unit includes an arc-shaped rail, a guide rod, a holder, and positioning meters. A second sliding block is connected to the three-dimensional regulating unit; the arc-shaped rail is arranged and slides on the second sliding block, and can be subjected to in-situ rotation around a vertical axis at any angle; the three-dimensional regulating unit drives the arc-shaped rail to move in three dimensions of up-down, left-right, and front-back dimensions; the guide rod can slide along the arc-shaped rail and moves long a long axial direction of the guide rod; and the holder is arranged on the guide rod for fixing a surgical instrument. There are two positioning meters, and rays sent by the two positioning meters, along with a long axis of the holder, are parallel to or coincide with a radial line of the arc-shaped rail. The three lines are located on a same plane, which is parallel to or coincide with the plane where the arc-shaped rail is located. The three lines intersect at one point.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, in particular to a detachable and assembled arc-shaped precise positioning device. Background technique

[0002] Minimally invasive spine technology is to reduce the trauma to surrounding tissues as much as possible on the premise of maintaining the curative effect of surgery, so as to achieve small surgical incision, less tissue damage, light systemic reaction, fast recovery period and good psychological effect. At present, the minimally invasive technique of the spine is developing vigorously, and has achieved good practical results and good social benefits in the clinical treatment of spinal diseases. More and more spine surgeons have begun to pay attention to and develop the minimally invasive technique of the spine. However, minimally invasive spinal techniques require precise surgical operations within a limited field of view and must rely on the positioning of imaging equipment. T...
