Electrode locking device

Abstract

The invention provides an electrode locking device which comprises a cranial hole seat, an electrode clamp and a cranial hole cover, the cranial hole seat comprises a mounting part and a fixing part, and the fixing part is arranged at the near end of the mounting part and surrounds the mounting part; the electrode clamp has an open state and a closed state, is embedded into the mounting part, and clamps an electrode led out from the far end of the mounting part when the electrode clamp is switched from the open state to the closed state; and the cranial hole cover is combined with the fixing piece and is used for sealing the near end of the mounting piece. As one part of the electrode locking device can sink into the skull, the thickness of the protrusions on the surface can be reduced while the overall thickness of the device does not need to be reduced, and a series of problems that due to the fact that the thickness of the device is reduced, the device is prone to breakage, installation is affected, disassembly is inconvenient, and an electrode is prone to displacement can be solved.

Description

[0001] This case is the application number: 202011134386.7, the name of the invention: a divisional application of a Chinese patent for an electrode locking device technical field [0002] The present invention relates to the technical field of medical instruments, in particular to an electrode locking device. Background technique [0003] Parkinson's disease is a common neurodegenerative disease, which is more common in the elderly, with an average age of onset around 60 years old. The main pathological change in Parkinson's disease is the degeneration and death of dopaminergic (DA) neurons in the substantia nigra, resulting in a significant decrease in striatal DA content. Parkinson's disease is mainly manifested by resting tremor, bradykinesia, postural gait disturbance, etc., which will have a great impact on the life of patients. [0004] With the development of modern medical technology, the use of electrodes to stimulate the subthalamic nucleus or the medial globus p...

AI Technical Summary

Problems solved by technology

[0010] 1. After the thickness of the electrode locking device is made thinner, its strength has a great risk, and it may break during the operation of the doctor or the use of the patient after the operation

[0011] 2. After the thickness of the electrode locking device is made thinner, the base in the electrode locking device needs to be bent and deformed to fit the skull, and the thin parts have a large bending strain, which may affect the installation of the clamping parts, thereby affecting the electrode locking

[0012] 3. After the electrode locking device is thinned, the size of the buckle is very limited because most of the parts are fitted with snaps, which will affect the stability of the lid after snapping and the convenience of disassembly.

[0013] 4. After the thickness of the electrode locking device is made thinner, the electrode is coiled around the base and may be displaced to the cover, causing discomfort to the patient due to friction with the scalp
