CN224220586UCN 224220586 UCN224220586 UCN 224220586UCN-224220586-U

Abstract

The application relates to a flexible electrode fixing anchor, and belongs to the technical field of medical appliances. When the flexible electrode anchor is used, two catheters of the electrode are directly placed into the through hole in the middle of the anchor from the opening according to the implantation position of the electrode, and then the surgical suture is bound through the binding wire groove, so that the catheters do not need to pass through the through hole from one end as in the prior art. The flexible electrode is fixedly anchored to the body's muscle or fascia tissue by surgical sutures passing through the binding-wire holes. After binding, the opening can be closed, so that the catheter is contracted, no relative movement exists between the fixed anchor and the catheter, and the fixation is firmer. The opening can also discharge the gas in the main body, which is convenient for the direct placement of the catheter.

Description

Flexible electrode anchor Technical Field The application belongs to the technical field of medical appliances, and particularly relates to a flexible electrode fixing anchor. Background Spinal cord electrical stimulation devices are commonly used clinically to inhibit pain, treat spinal cord injuries, and the like. Spinal cord stimulation electrodes are treated by stimulating spinal nerves, and the electrodes need to be immobilized in the epidural space of the spinal cord. In the prior art, electrodes are currently anchored to bone or surrounding tissue in the vicinity of the stimulation site, typically by means of anchors. The prior art electrode anchors, which are structured as in chinese patent documents CN107029346B and CN107252524A, require that the electrode be advanced through the electrode anchor from one end, which is inconvenient for some operations when only one catheter is required to be passed through, but advanced penetration can be achieved. However, if a nerve stimulating electrode having two catheters is used, the two catheters may rub against each other while passing through the anchor, resulting in difficulty in operation. Disclosure of utility model The utility model aims to solve the technical problem of providing a flexible electrode anchor which does not need to penetrate a catheter from one end in order to solve the defects in the prior art. The technical scheme adopted for solving the technical problems is as follows: a flexible electrode anchor, comprising: The main body is made of cylindrical silica gel, a through hole is formed in the middle of the main body, and an opening communicated with the through hole is formed in one side of the main body in the axial direction; The main body outer wall is provided with a side wing, the side wing is provided with a binding wire hole, the circumferential direction of the main body outer wall is provided with a binding wire groove, and the binding wire groove and the binding wire hole are aligned on the longitudinal section of the main body. Preferably, the flexible electrode anchor of the present utility model, the through hole is an elliptical through hole. Preferably, the flexible electrode fixing anchor of the present utility model has two circular through holes, and each circular through hole is provided with an opening. Preferably, the flexible electrode anchor of the present utility model, the lateral wings are disposed at both sides of the body. Preferably, the flexible electrode anchor of the present utility model, the upper side of the body has one side wing and the lower side of the body has two side wings. Preferably, the flexible electrode anchor of the present utility model has an elastic member disposed within the body. Preferably, the flexible electrode anchor of the present utility model, the elastic member is a C-shaped memory metal member. The beneficial effects of the utility model are as follows: The flexible electrode anchor of the present utility model, the binding wire hole and the binding wire groove are used for binding a surgical suture, and the surgical suture passes through the binding wire hole and is wound along the binding wire groove for several weeks. When the flexible electrode anchor of the embodiment is used, two catheters of the electrode are directly placed into the through hole in the middle of the anchor from the opening according to the implantation position of the electrode, and then the surgical suture is bound through the binding wire groove, so that the catheters do not need to pass through the through hole from one end as in the prior art. The flexible electrode is fixedly anchored to the body's muscle or fascia tissue by surgical sutures passing through the binding-wire holes. After binding, the opening can be closed, so that the catheter is contracted, no relative movement exists between the fixed anchor and the catheter, and the fixation is firmer. The opening can also discharge the gas in the main body, which is convenient for the direct placement of the catheter.
