Problems solved by technology
Although these common methods can play the role of fixing the electrodes, they will cause large lateral or vertical displacement of the electrodes during the fixation process, which will affect the surgical effect, or the electrodes will still move within the skull for a period of time after the operation. space, resulting in poorer results over time after surgery

The invention discloses a fixing device for medical instruments. The fixing device for medical instruments comprises a bone hole base and a locking gasket, wherein the bone hole base is used for beingplaced into a bone hole of a skull, and a through hole running through an axial direction of the bone hole base is formed in the bone hole base; the locking gasket can be fixed relative to the position of the bone hole base, the locking gasket comprises an integrally formed gasket base, the gasket base is provided with two fixed arms and two locking arms, the two locking arms are used for maintaining pretightening force through elastic parts and are used for clamping the medical instruments placed inside the skull, and the two fixed arms are positioned on the outer sides of the respectively corresponding locking arms respectively and are used for being mounted on the inner side of the through hole. According to the fixing device for medical instruments, the clamping for the medical instruments such as electrodes is realized by using the two locking arms of the locking gasket, the locking gasket is fixed in the bone hole base, and the bone hole base can be used for fixing the skull, sothat the fixation for the medical instruments such as electrodes is realized conveniently, the success rate of deep brain stimulation operations is improved in the step of electrode fixation, and theoperation result is improved.
Description
technical field [0001] The invention relates to the technical field of implantable medical systems, in particular to a medical device fixing device. Background technique [0002] The deep brain stimulation system is a kind of implanted neurostimulation system, which mainly includes a pulse generator implanted in the body, electrodes and external control devices. The electrodes are connected with the pulse generator, and the pulse generated by the pulse generator is transmitted to specific nerve parts to generate electrical stimulation, so as to restore the normal human body functions of the corresponding parts. During the electrode implantation process, the doctor first determines the target position of the patient's brain through a three-dimensional stereotaxic device, and then makes a bone hole in the appropriate skull according to the target position, and inserts the electrode wire into the corresponding target through the bone hole. Test at the point position. If the ef...
