Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an electrode protection cap. Background Art

[0002] DBS (Deep Brain Stimulation) is an effective technique for treating advanced and drug-resistant movement disorders and mental disorders. It is particularly effective in the treatment of Parkinson's disease.

[0003] When performing a DBS operation, local anesthesia of the head is required when placing the electrode, and general anesthesia is required when placing the extension wire and the pulse generator later. These two steps may be done in stages. Therefore, in order to prevent infection, after the electrode is implanted into the skull and fixed, the electrode needs to be temporarily coiled and inserted under the scalp, and the scalp incision is temporarily sutured. When the electrode is coiled and inserted under the scalp, if the connection end of the electrode is not protected, blood will enter the electrode, and at the same time, it may be mechanically bent, which may damage the connection end. At this time, using an electrode protection cap to cover the connection end of the electrode can play a role in protection and preventing leakage. Summary of the Invention

[0015] In a preferred embodiment of the present invention, the sleeve and the sealing ring of the electrode protection cap are made of a soft material, and preferably processed and formed by a soft rubber material;

[0016] The locking member is made of a polymer material and is processed and formed by injection molding.

[0048] According to the embodiment of the present invention, directly tightening and loosening the screw 5 can achieve the fixation and loosening of the electrode 4. The locking part realizes the clamping of the electrode 4 by screwing the screw 5 into the locking member 2 to compress the soft rubber in the cavity of the sleeve 1 to deform, achieving a locking effect. The method of locking the electrode with soft rubber can also avoid the problem of force deformation of the electrode contact.

The open end of the sleeve 1 is formed with a stepped tapered hole. The tapered portion of the stepped tapered hole extends in the reverse direction of the open end and the hole diameter decreases. The stepped tapered hole forms a stepped hole section with a large hole diameter at the open end. The stepped hole section with a large hole diameter is used to accommodate the sealing ring. The sealing ring 3 is installed at the opening of the open end of the sleeve 1 and is hermetically connected to the sleeve 1. When the electrode 4 is inserted into the sleeve 1 from inside the sealing ring 3, the electrode 4 is hermetically connected to the sealing ring 3.

[0052] In a preferred embodiment of the present invention, the diameter of the sleeve 1 of the above electrode protection cap gradually increases from the closed end to the open end. Its technical effect is that the locking member 2 is assembled from the end direction of the sleeve 1 to the locking member installation position of the sleeve 1, without the need to be integrally molded in the form of an insert. There is no requirement for the high-temperature resistance of the locking member 2, and more materials can be selected.
