Technical Field
[0001] This utility model belongs to the field of ablation electrodes, specifically, it relates to a rotary telescopic pen for ablation electrodes. Background Technology
[0002] The main function of ablation electrodes is to eliminate abnormal electrical signals inside the heart that may cause cardiac arrhythmias, such as atrial fibrillation and ventricular fibrillation.
[0003] Most existing ablation electrodes have a fixed needle length. However, during surgery, superficial and deep surgeries are often performed in the same procedure. In such cases, medical staff need to be equipped with multiple ablation electrodes of different fixed lengths to handle the corresponding surgeries, which increases the workload of medical staff and prolongs the operation time.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rotary telescopic pen for ablation electrodes, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A rotary telescopic pen for ablation electrodes includes: a handle, a handle cap threadedly connected to the handle, an insulating sleeve fixedly connected to one side of the handle, a movable plate elastically and slidably fitted inside the handle, an electrode needle disposed on one side of the movable plate and located inside the insulating sleeve, and a cable passing through the handle cap connected to one side of the electrode needle. The handle cover is provided with a tensioning component connected to the movable plate, and the handle cover is provided with a self-locking transmission component that drives the tensioning component. A knob connected to the self-locking transmission component is rotatably fitted on one side of the handle cover.
[0007] Optionally, a spring is fixedly connected between the handle cover and the movable plate.
[0008] Optionally, the handle cover has an inner cavity, and the tightening component and the self-locking transmission component are located within the inner cavity.
[0009] Optionally, the tensioning assembly includes a rotating roller rotatably fitted within the inner cavity, a reel disposed around the circumference of the rotating roller, and a pull rope wound on the reel and fixedly connected to one side of the moving plate. The rotating roller cooperates with the self-locking transmission assembly.
[0010] Optionally, the self-locking transmission assembly includes a worm gear disposed on the periphery of the rotating roller, a worm gear rotatably engaged in the inner cavity and meshing with the worm gear, and a knob disposed at the end of the worm gear that passes through the handle cover.
[0011] Optionally, the outer surface of the handle is provided with an external thread, and the inner side of the handle cover is provided with an internal thread that engages with the external thread.
[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: By using a tensioning component inside the handle cover, when it is necessary to adjust the length of the electrode needle in the handle and the insulating sleeve, turning the knob drives the tensioning component through the self-locking transmission component, which can tighten or loosen the moving plate. The moving plate moves elastically inside the handle, causing the electrode needle to move out of the insulating sleeve, which facilitates the adjustment of the length of the electrode needle according to the needs of the surgery. The operation is convenient, making the surgery quick and easy, and shortening the operation time.

Detailed Implementation
[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] Please see Figure 1-3As shown, this embodiment provides an ablation electrode rotary telescopic pen, including: a handle 1, a handle cover 2 threadedly connected to the handle 1, an insulating sleeve 3 fixedly connected to one side of the handle 1, a movable plate 4 elastically and slidably fitted inside the handle 1, an electrode needle 9 located inside the insulating sleeve 3 on one side of the movable plate 4, and a cable 11 connected to one side of the electrode needle 9 that passes through the handle cover 2. The handle cover 2 is provided with a tensioning component 7 connected to the movable plate 4. The handle cover 2 is provided with a self-locking transmission component 10 that drives the tensioning component 7. A knob 8 connected to the self-locking transmission component 10 is rotatably fitted on one side of the handle cover 2.
[0019] By using the tensioning component 7 provided inside the handle cover 2, when it is necessary to adjust the length of the electrode needle 9 in the handle 1 and the insulating sleeve 3, turning the knob 8 drives the tensioning component 7 through the self-locking transmission component 10, which can tighten or loosen the moving plate 4. The moving plate 4 moves elastically inside the handle 1, causing the electrode needle 9 to move out of the insulating sleeve 3, which makes it easy to adjust the length of the electrode needle 9 according to the needs of the surgery. The operation is convenient, making the surgery convenient and quick, and shortening the operation time.
[0020] like Figure 2-3 As shown, in this embodiment, a spring 5 is fixedly connected between the handle cover 2 and the moving plate 4; the handle cover 2 is provided with an inner cavity 6, and the tensioning component 7 and the self-locking transmission component 10 are located in the inner cavity 6; like Figure 2-3 As shown, the tensioning assembly 7 in this embodiment includes a rotating roller 701 rotatably fitted in the inner cavity 6, a reel 702 disposed around the rotating roller 701, and a pull rope 703 fixedly connected to one side of the moving plate 4 wound on the reel 702. The rotating roller 701 cooperates with the self-locking transmission assembly 10. The self-locking transmission assembly 10 includes a worm gear 1001 disposed around the rotating roller 701, a worm 1002 rotatably fitted in the inner cavity 6 and meshing with the worm gear 1001, and a knob 8 disposed at the end of the worm 1002 that passes through the handle cover 2.
[0021] When adjusting the length of the electrode needle 9, turn the knob 8. The rotation of the knob 8 drives the worm gear 1002 to rotate, which in turn drives the worm wheel 1001 to rotate. The rotation of the worm wheel 1001 drives the rotating roller 701 to rotate, which in turn drives the reel 702 to rotate. The rotation of the reel 702 can loosen the wound pull rope 703. The loosening of the pull rope 703 can move the moving plate 4. The moving plate 4 moves within the handle 1 through the elastic movement of the spring 5, which moves the electrode needle 9 out of the insulating sleeve 3. This makes it easy to adjust the length of the electrode needle 9 according to the needs of the surgery. The operation is convenient, making the surgery quick and easy, and shortening the operation time.
[0022] like Figure 1As shown, the outer surface of the handle 1 in this embodiment is provided with an external thread, and the inner side of the handle cover 2 is provided with an internal thread that meshes with the external thread. The engagement of the external thread and the internal thread allows the handle cover 2 to be disassembled and assembled with the handle 1, thereby facilitating the cleaning and disinfection of the electrode needle 9 in the handle 1.
