Brain surgery stereotactic instrument with double-locking function and locking method thereof

Abstract

The invention discloses a brain surgery stereotactic instrument with a double-locking function and a locking method thereof; the brain surgery stereotactic instrument includes a plurality of mechanical arms, coils, a locking button and a plurality of manual locking components; each two adjacent mechanical arms are connected through an electromagnetic rotating shaft and an electromagnetic bearing;the coils are arranged on the electromagnetic rotating shafts; the locking button is pressed down, and then the mechanical arms are locked; the plurality of manual locking components are respectivelyarranged on the ends of the electromagnetic rotating shafts and each include a box body, a rotating rod, a wedge-shaped sliding block connected with the rotating rod, a pressing block and a first compression spring connected with the pressing block. After the wedge-shaped sliding blocks are driven to away from the pressing blocks by the rotating rods, the pressing blocks are pressed to lock the electromagnetic rotating shafts; after the wedge-shaped sliding blocks are driven to separate the pressing blocks and the electromagnetic rotating shafts by the rotating rods, the electromagnetic rotating shafts can rotate around the electromagnetic bearings. With the arrangement, the double locking of the brain surgery stereotactic instrument is achieved, and the brain surgery stereotactic instrument is simple in structure, convenient in operation, trouble-saving, labor-saving and low in cost.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a brain surgery stereotaxic instrument with double locking functions and a locking method. Background technique [0002] With the continuous development of the brain surgery system, the current brain surgery system can perfectly combine the surgery planning system, the navigation system and the stereotaxic micro-invasive technology, which broadens the scope of application, improves the safety of surgery, and reduces the burden on patients. pain. [0003] Taking the CRAS robotic brain surgery system as an example, the robotic brain stereotaxic uses imaging positioning (CT, MRI or DSA) and stereotaxic instrument guidance to locate the lesion target, and implants microscopic instruments such as biological needles and microelectrodes into the brain. For specific targets, various diseases of the central nervous system can be diagnosed and treated by recording electrophysiol...
