Embodiment 1

[0040] A specific embodiment of the present invention, such as Figure 1-9 As shown, an electrode fixing device is disclosed, one end of the electrode is connected to a pulse generator, and the other end is inserted into the brain for stimulation treatment, and is used in a deep brain electrical stimulation system. The electrode fixing device includes a base 1 and a rotating clamping assembly, and the clamping, positioning and loosening of the electrode can be realized by rotating the rotating clamping assembly.

[0041] Compared with the prior art, the electrode fixing device provided by this embodiment positions, clamps and releases the electrode by rotating the clamping assembly, which is small in size and easy to operate; it does not need to assemble the base and locking device on site during surgery, The operator's assembly procedure is reduced, and at the same time, it is reduced that the component is stuck on site and accidentally pulled to the electrode, and the accura...

Embodiment 2

[0062] An electrode fixing method, using the above electrode fixing device, the steps include:

[0063] S1: Determine the target position of the patient's brain to be treated through a three-dimensional stereotaxic device;

[0064] S2: Make a bone hole in the appropriate skull according to the target position;

[0065] S3: installing the electrode fixing device, inserting the electrode into the bone hole;

[0066] Clamp the electrode fixing device to the bone hole, and after the installation is stable, open the rotating clamping assembly on the base 1 of the electrode fixing device; preferably, the locking piece 3 is retracted by rotating the locking ring 2 to perform the opening action, and further , the rotation of the locking ring 2 causes the locking ring 2 to rotate clockwise or counterclockwise by snapping a rod-shaped tool into the rotation locking hole 22 on the locking ring 2 .

[0067] Insert the electrode into the corresponding target position through the opening ...

Abstract

The invention relates to an electrode fixing device, belonging to the technical field of medical instruments for deep brain stimulation. The invention aims to solve the problems that an electrode fixing device in the prior art is inaccurate in electrode positioning, poor in stability, tedious in assembly procedure, unbalanced in clamping position and easy to loosen. The electrode fixing device comprises a base and a rotary clamping assembly, wherein the rotary clamping assembly comprises a locking ring and a plurality of locking pieces; the locking ring and the multiple locking pieces are arranged on the base; and the multiple locking pieces stretch out or retract in space defined by the base and the locking ring. The electrode fixing device is small in size and convenient to operate, and a locking device does not need to be assembled on site when used in an operation, so assembling procedures of operators are reduced, the situation that an electrode is accidentally pulled when the part is assembled on site is reduced, and electrode positioning accuracy and stability can be improved.

Description

technical field [0001] The invention relates to the technical field of deep brain stimulation medical devices, in particular to an electrode fixing device. Background technique [0002] The deep brain stimulation system is a kind of implantable neurostimulation system, which mainly includes a pulse generator and electrodes implanted in the body. During the operation of implanting electrodes in patients, the positioning accuracy and positioning stability of the electrodes are very important, and the fixing device of the electrodes is the key to solve the above problems. [0003] The electrode fixing base and the electrode locking clip of the existing electrode fixing device are separately set. When in use, the electrode fixing base is first fixed in the bone hole of the skull, and then the electrode is inserted into the bone hole, and then the electrode locking clip is assembled to the electrode fixing Then use tools to lock the electrode locking clip to fix the electrode. ...
