Embodiment

[0035] At present, when using an electrosurgical pen, especially an electrode tip for radiofrequency ablation of the spine, it is necessary to continuously adjust the position of the electrode end to adapt to the surgical treatment of different tissues. However, the electrosurgical pencil in the prior art can only make the electrode tip extend and retract during surgery. Single adjustment function, inconvenient to use.

[0036] In view of this, the designer has designed an angle-adjustable spinal radiofrequency ablation electrode blade, the electrode can be rotated and slid, the adjustment method is various, the adjustment is flexible, the use is convenient, it is beneficial to the operation, and the operation efficiency and quality are improved.

[0037] see Figure 1-Figure 3 In this embodiment, the angle-adjustable spinal radiofrequency ablation electrode head includes a fixed handle 100 , a sleeve 200 , a movable handle 300 , an elastic connector 400 and an electrode 500 ....

Abstract

The invention provides an angle-adjustable spinal radiofrequency ablation electrode tool bit. The angle-adjustable spinal radiofrequency ablation electrode tool bit comprises a fixed handle, a sleeve, a movable handle, an elastic connecting piece and an electrode, the sleeve is provided with an assembly cavity, and the near end of the sleeve is connected with the fixed handle; the movable handle comprises an inner cylinder and an outer cylinder, the outer cylinder is arranged outside the inner cylinder in a sleeving mode, the outer cylinder and the inner cylinder are rotatably matched and relatively fixed in the axis extending direction of the inner cylinder or the outer cylinder, the inner cylinder and the outer cylinder are both arranged in the assembly cavity, and the inner cylinder and the assembly cavity are slidably matched in the axis extending direction of the sleeve. The inner cylinder and the assembling cavity are relatively fixed in the circumferential direction of the inner cylinder; one end of the elastic connecting piece is connected with the fixed handle, the other end of the elastic connecting piece is connected with the inner cylinder, and the elastic connecting piece is used for making the inner cylinder slide away from the fixed handle; the electrode is provided with an eccentrically-arranged electrode tool bit, and the electrode is arranged in the sleeve in a penetrating mode and fixedly connected with the outer cylinder. The electrode can be rotated and slidably adjusted, the adjusting mode is flexible, and use is convenient.

Description

technical field [0001] The present application relates to the field of medical equipment, and in particular, to an angle-adjustable spinal radiofrequency ablation electrode blade. Background technique [0002] The medical electric knife pen is a relatively common medical device used in surgery. The main function of the electric knife pen is tissue electric cutting and coagulation to stop bleeding. It usually includes a pen body, a functional tube arranged at the front end of the pen body, and a function tube arranged inside the pen body. The circuit board system electrically connected with the functional tube is arranged in the functional tube with electrodes. Usually in the surgical process with the electric knife pen, some parallel surgical instruments need to be used together or crossed, such as laser fiber, irrigation suction, biopsy forceps, lighting fiber, endoscope, etc. When the electric knife pen works with these parallel surgical instruments, it is usually It requ...
