Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an implantable deep brain stimulation electrode lead kit. Background Technology

[0002] Implantable medical systems typically include implantable neurostimulation systems, implantable cardiac stimulation systems (commonly known as pacemakers), and implantable drug delivery systems. Implantable neurostimulation systems include deep brain stimulation (DBS), implantable cortical nerve stimulation (CNS), implantable spinal cord stimulation (SCS), implantable sacral nerve stimulation (SNS), and implantable vagus nerve stimulation (VNS), etc. Taking an implantable neurostimulation system as an example, it mainly consists of an implanted pulse generator, electrodes, and an external control device. The procedure involves connecting a pulse generator to electrodes, transmitting the pulses generated by the generator to the electrodes. These pulse signals are then transmitted to the heart or specific nerve areas for electrical stimulation, restoring normal bodily functions. However, during surgery, the brain electrode leads are often suspended and unsecured when the needle is inserted or removed. After removing the guide wire, directly pressing the lead against the skull ring with the skull cap can cause horizontal and vertical misalignment, complicating the procedure and leading to unsatisfactory treatment results. Furthermore, adding another layer of skull cap to the scalp increases the overall height of the fixation device, causing discomfort and aesthetic issues for the patient.

[0003] To address the above issues, existing technology (publication number CN102526880B) discloses a brain electrode lead fixing device, comprising: a foramen ring, the foramen ring including a foramen junction for fixing the foramen ring to the foramen, the inner wall of the foramen junction forming an electrode hole for the brain electrode lead to pass through; and a foramen plug, the foramen plug having at least one groove for passing through and fixing the brain electrode lead, the foramen plug being disposed within the electrode hole to close the electrode hole. Compared with the prior art, when the electrode lead reaches the designated target point through the lead needle, the doctor pulls out the lead needle, at which point the foramen plug immediately clamps the electrode lead tightly, preventing displacement of the electrode lead in the horizontal and vertical directions, and firmly and accurately positioning the electrode lead at the designated target point, avoiding target point displacement during the doctor's operation of closing the foramen ring.

[0004] However, during the use of the above-mentioned device, the bone hole cover is connected to the bone hole base by pressing, which may cause injury to the patient when the bone hole cover is pressed in. Utility Model Content

[0005] Purpose of the invention: The main technical problem to be solved by this utility model is to provide an implantable deep brain stimulation electrode lead kit, which can solve the problem that the bone hole cover is connected to the bone hole base by pressing, which may cause harm to the patient when the bone hole cover is pressed in.

[0006] Technical solution: To solve the above-mentioned technical problems, according to one aspect of the present utility model, more specifically, an implantable deep brain stimulation electrode lead kit includes a bone hole base, four fixing slots are evenly opened at the bottom of the bone hole base, an electrode is snapped into the inside of the fixing slot on the right front, a bone hole cover is provided on the top of the bone hole base, connecting devices are symmetrically provided on the left and right sides between the bone hole base and the bone hole cover, and a fastening device is provided between the bone hole base and the bone hole cover above the fixing slot.

[0007] Furthermore, the connecting device includes a connecting seat, which is symmetrically fixed to the top left and right sides of the bone hole base. A mounting groove is formed in the middle of the side of the connecting seat away from the middle of the bone hole base. A spring is fixed to the bottom of the mounting groove. A connecting block is fixed to the end of the spring away from the bottom of the mounting groove. Connecting grooves are symmetrically formed on the left and right sides of the bottom of the bone hole cover. A connecting hole is formed in the middle of the inner wall of the connecting groove away from the middle of the bone hole cover. The connecting seat is inserted into the inside of the connecting groove, and the connecting block is inserted into the inside of the connecting hole.

[0008] Furthermore, the fastening device includes a bolt, and four mounting holes are evenly provided on the top of the bone hole cover. The upper part of the outer wall of the bolt is rotatably connected to the inner wall of the mounting hole. A guide tube is fixed to the bottom of the bone hole cover around the mounting hole. A fastening block is provided below the bolt. A threaded groove is provided in the middle of the top of the fastening block. The bolt is screwed into the inside of the threaded groove. A guide groove is provided on the top of the fastening block around the threaded groove. The guide tube is inserted into the inside of the guide groove.

[0009] Furthermore, the distance between the left and right outer walls of the fixing groove is equal to the diameter of the electrode.

[0010] Furthermore, the outer wall of the connecting seat is fitted with the inner wall of the connecting groove, and the outer wall of the connecting block is fitted with the inner wall of the connecting hole.

[0011] Furthermore, the threads of the bolt match the threads of the threaded groove.

[0012] Beneficial effects: The connecting device securely connects the bone hole base and the bone hole cover, ensuring their stability and preventing potential injury to the patient during connection. To connect, press the two connecting blocks and insert the connecting slots into the outside of the connecting seat. When the connecting blocks are aligned with the connecting holes, the spring force causes the connecting blocks to insert into the connecting holes, completing the connection between the bone hole base and the bone hole cover. To separate the bone hole base and cover, press both connecting blocks simultaneously and pull the bone hole cover upwards. After attaching the electrode to the nearest fixing slot, the electrode can be secured using the corresponding fastening device to prevent movement during use. Rotating the bolt, under the action of the threaded groove, guide groove, and guide tube, moves the fastening block downwards or upwards, tightening or loosening the electrode.
