Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical equipment technology, specifically relating to an ablation electrode sliding telescopic pen. Background Technology
[0002] The ablation electrode telescopic pen is a precision medical device used in minimally invasive surgery. It delivers radiofrequency or microwave energy through electrodes to target and ablate diseased tissue. Its core feature is its telescopic pen design, allowing for precise intraoperative positioning by adjusting the extension length (typically 5–20 mm) and working angle of the electrode probe via a handle. The pen body is made of insulating, high-temperature resistant material and integrates a temperature sensor and intelligent locking mechanism to ensure operational stability. It is primarily used in tumor radiofrequency ablation and nerve block procedures, offering advantages such as small incisions, flexible adjustment, and controllable energy output.
[0003] A liquid sealing sleeve is provided between the electrode sleeve and the electrode body of the sliding telescopic pen to ensure the seal between the two. However, after long-term use, the sealing performance of the liquid sealing sleeve will gradually decrease, which can easily cause liquid to seep into the interior of the sliding telescopic pen, thereby affecting its performance.

Detailed Implementation
[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1
[0017] Reference Figure 1-5 This is an embodiment of the present invention, which provides an ablation electrode sliding telescopic pen, comprising: The pen body mechanism 100 includes a handle housing 110, two buttons 120 disposed on the surface of the handle housing 110, an electrode sleeve 130 and an electrode body 140 respectively fixedly installed at the ends of the handle housing 110, and a sealing sleeve 150 for increasing the sealing between the electrode sleeve 130 and the electrode body 140. The electrode sleeve 130 is fitted onto the surface of the electrode body 140; The replacement mechanism 200 includes a disassembly and assembly component 210 for facilitating the replacement of the sealing sleeve 150.
[0018] The sealing sleeve 150 can be easily replaced by disassembling and assembling component 210, which solves the problem that the sealing sleeve 150 on the traditional sliding telescopic pen is inconvenient to replace and affects the sealing performance between the electrode sleeve 130 and the electrode body 140 for a long time. This makes it easier to replace the sealing sleeve 150 and improves the sealing performance between the electrode sleeve 130 and the electrode body 140.
[0019] Specifically, the disassembly and assembly component 210 includes an external threaded cylinder 211 disposed at the end of the electrode sleeve 130, a threaded groove 212 opened inside the electrode sleeve 130, a sealing gasket 213 fixedly installed at the end of the electrode sleeve 130, and a sealing plate 214 sleeved on the surface of the external threaded cylinder 211 and used in conjunction with the sealing gasket 213.
[0020] Furthermore, the end of the external threaded cylinder 211 is threaded into the inside of the electrode sleeve 130 through the threaded groove 212, and the sealing sleeve 150 is fixedly installed inside the external threaded cylinder 211 and is sleeved on the surface of the electrode body 140.
[0021] Preferably, a stop 215 is fixedly installed inside the electrode sleeve 130, and the surface of the stop 215 fits with the port of the external threaded cylinder 211.
[0022] The stop block 215 serves to block and limit the external threaded cylinder 211, and at the same time limits the electrode body 140, thereby improving the stability of the electrode body 140 in use.
[0023] Furthermore, the surface of the external threaded cylinder 211 is fixedly equipped with several arc-shaped protrusions 216 for anti-slip purposes.
[0024] The circular arc protrusion 216 is used to increase the friction on the surface of the external threaded cylinder 211, thereby facilitating the rotation and twisting of the external threaded cylinder 211, so as to facilitate the installation and disassembly of the external threaded cylinder 211 and the replacement of the sealing sleeve 150.
[0025] Furthermore, a positioning ring is fixedly installed on the surface of the sealing plate 214, and the positioning ring is sleeved on the end of the external threaded cylinder 211, with the size of the positioning ring matching the size of the end of the external threaded cylinder 211.
[0026] The positioning ring is used to position and install the external threaded cylinder 211, so that the external threaded cylinder 211 and the electrode sleeve 130 are precisely connected.
[0027] When the sealing sleeve 150 needs to be replaced periodically during use, the user holds the end of the external threaded cylinder 211 and rotates the external threaded cylinder 211 so that the end of the external threaded cylinder 211 gradually exits the inside of the electrode sleeve 130 until the external threaded cylinder 211 is completely exited from the inside of the electrode sleeve 130. Then, the sealing sleeve 150 inside the external threaded cylinder 211 is replaced, and then the external threaded cylinder 211 is installed inside the electrode sleeve 130. The external threaded cylinder 211 is fitted onto the surface of the electrode body 140 and moved so that the end of the external threaded cylinder 211 moves to the end of the electrode sleeve 130. Then the external threaded cylinder 211 is rotated so that the end of the external threaded cylinder 211 is completely screwed into the interior of the electrode sleeve 130 and blocked by the stop block 215.
[0028] In summary, by assembling and disassembling component 210, the sealing sleeve 150 can be easily replaced, which solves the problem that the sealing sleeve 150 on traditional sliding telescopic pens is inconvenient to replace and affects the sealing performance between the electrode sleeve 130 and the electrode body 140 over a long period of time. This achieves the goal of facilitating the replacement of the sealing sleeve 150 and improving the sealing performance between the electrode sleeve 130 and the electrode body 140.
