Description

Technical Field

[0001] This utility model belongs to the field of electrosurgical knives, specifically relating to a multifunctional telescopic electrode knife. Background Technology

[0002] Electrosurgical knives (electrosurgical instruments) are indispensable tools in modern surgery. Their core function is to achieve tissue cutting and coagulation through high-frequency current. Traditional electrosurgical knives are designed in different shapes according to surgical needs. Among them, the flat-tip electrosurgical knife and the angled-tip electrosurgical knife are suitable for the following scenarios due to their structural differences: The scalpel-tipped electrosurgical unit, with its flat and precise blade design, is often used for delicate tissue cutting (such as nerve and blood vessel separation) and superficial coagulation; the angled tip of the beveled electrosurgical unit can increase the contact area, making it suitable for surgical procedures such as scraping. However, existing electrosurgical units are used separately, and there is no electrosurgical unit that integrates the two. Surgeons need to frequently change different electrosurgical units during complex surgeries, which increases the operation interruption time and affects surgical efficiency. Therefore, there is a need to propose a multifunctional telescopic electrode knife. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background art and provide a multifunctional telescopic electrode knife.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A multifunctional telescopic electrode knife includes a functional tube, a beveled tube, a tongue electrode tube, a connecting tube, and a pen body. The tongue electrode tube is disposed inside the functional tube, and the connecting tube is disposed between the tongue electrode tube and the functional tube. The front end of the beveled tube is fixedly connected to the connecting tube and is located outside the tongue electrode tube. The functional tube is fixed inside the pen body.

[0005] This invention utilizes a beveled tube to connect the connecting tube, allowing the beveled tube to conceal the scalpel electrode tube and function as a beveled tube, facilitating the scraping function during surgery. When the beveled tube retracts, the scalpel is exposed, enabling electrocautery and electrocoagulation. It can also be adjusted to a suitable position to function as a smoking tube, achieving multiple functions, reducing the frequency of scalpel head replacements, and improving surgical efficiency.

[0006] A friction damping spring is provided between the functional tube and the connecting tube, and the friction damping spring is fixedly connected to the side wall of the connecting tube.

[0007] This invention increases the friction force between the connecting tube and the functional tube by using a friction damping spring, thereby achieving a damping effect and preventing movement after the tube has been extended and adjusted to the appropriate position.

[0008] The friction damping spring is made of conductive material.

[0009] The fixed tube has a waist-shaped sliding groove, and the bottom of the friction damping spring is formed with a protrusion. The protrusion passes through the connecting tube and is located in the waist-shaped sliding groove.

[0010] This invention limits the extension stroke by using a waist-shaped groove and protrusions to prevent the connecting tube from falling off. At the same time, it ensures that the blade tongue rotates along with the oblique tube, keeping the blade tongue at the tip of the oblique tube opening and ensuring a clear surgical field of vision.

[0011] Preferably, there are two waist-shaped sliding grooves, which are arranged symmetrically.

[0012] The blade electrode tube includes a fixed tube and a blade electrode head located at the front end of the fixed tube.

[0013] Preferably, the blade electrode head is straight.

[0014] Preferably, the diameter of the scalpel electrode head gradually decreases from the rear end to the front end of the pen body, making it suitable for more delicate surgeries.

[0015] Preferably, the pen body is further provided with a circuit board, which is located above the functional tube. A conductive spring (52) is provided below the circuit board. The conductive spring (52) is hook-shaped, and the bottom of the conductive spring (52) abuts against the outer wall of the functional tube.

[0016] This invention uses a conductive spring to abut against the functional tube to ensure stable current transmission. The connecting tube, fixing tube, blade electrode head, and beveled tube are all made of conductive materials. The outer wall of the beveled tube is provided with insulating material to facilitate manual extension and retraction through the beveled tube.

[0017] Preferably, the pen body has a two-part structure for easy disassembly, and a three-way valve is provided at the end of the pen body, which can be used to switch between smoking and non-smoking modes.

[0018] In summary, the beneficial effects of this utility model are as follows: 1. This utility model connects the connecting tube by pulling out the oblique tube, so that the oblique tube can hide the blade electrode tube and become an oblique tube for use, which facilitates the scraping function during surgery. When the oblique tube is retracted, the blade is exposed again, which can be used for electro-cutting, electrocoagulation and other functions. At the same time, it can also be adjusted to a suitable position so that the oblique tube can be used as a smoking tube, realizing multiple functions, reducing the number of times the blade head needs to be changed, and improving surgical efficiency. 2. This utility model increases the friction force between the connecting tube and the functional tube by using a friction damping spring, which plays a damping role and prevents the tube from moving after being adjusted to a suitable position through telescopic extension; 3. This utility model limits the extension stroke by setting the waist-shaped groove and the protrusion, preventing the connecting tube from falling off. At the same time, it allows the blade to rotate along with the oblique tube, ensuring that the blade is always at the tip of the oblique tube opening, thus ensuring the surgical field of vision.
