Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a high-frequency electrosurgical unit for superficial tumors with an adjustable insulating outer tube. Background Technology

[0002] Clinically, tumors located in the skin, skin appendages, and subcutaneous tissue are collectively referred to as superficial tumors. High-frequency electrosurgical units are electrosurgical instruments that replace traditional mechanical scalpels for tissue cutting. They utilize the thermal effect generated by high-frequency, high-voltage current contacting the tissue to vaporize and coagulate it, thereby achieving precise tumor removal and simultaneous hemostasis.

[0003] Currently, flat-tipped (blade-shaped) high-frequency electrosurgical units are widely used in clinical practice. However, in delicate surgeries targeting small, superficial tumors, the relatively large blade size of these units results in incisions that are not sufficiently minimally invasive. Furthermore, once the blade penetrates deep into the wound, the field of vision is limited, affecting surgical precision. In addition, when treating small, superficial tumors, the sides of the existing electrosurgical unit's blade are prone to contact with the skin, leading to local tissue thermal damage. This can potentially affect surgical outcomes, delay wound healing, and reduce postoperative aesthetics. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing high-frequency surgical electrosurgical units are large in size and the electrosurgical head is prone to damaging normal skin tissue.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is to provide a high-frequency electrosurgical unit for superficial tumors with an adjustable insulating outer tube, including a knife body, an electrosurgical head and an insulating outer tube. The electrosurgical head is fixedly installed inside the knife body and one end extends out of the knife body. The insulating outer tube is sleeved on the electrosurgical head and can slide along the electrosurgical head.

[0006] Optionally, the blade body is provided with a sliding groove, and a slider is provided in the sliding groove. The slider is connected to the insulating outer tube, and the slider can slide in the sliding groove, thereby driving the insulating outer tube to extend and retract.

[0007] Optionally, the sliding groove is provided with a linear slide rail arranged along the axis of the electric knife head, and the slider is disposed on the linear slide rail.

[0008] Optionally, the linear slide rail is provided with a micro-tooth structure, and the slider makes contact with the linear slide rail through the micro-tooth structure.

[0009] Optionally, the diameter of the end of the electric knife head extending out of the knife body gradually decreases in the direction away from the knife body, forming the tip of the electric knife head.

[0010] Optionally, the insulating outer tube is made of a flexible thin-walled insulating material.

[0011] Optionally, the end of the insulating outer tube near the tip of the electric knife head is a pointed structure that mates with the tip of the electric knife head, and the insulating outer tube is tightly fitted to the electric knife head within its sliding range.

[0012] Optionally, one end of the electric knife head located inside the knife body is connected to an external high-frequency power supply.

[0013] Optionally, two operation buttons are provided on the same side of the sliding groove below. These operation buttons are connected to an external high-frequency power supply and control its on / off state.

[0014] Optionally, the blade body has anti-slip textures on its exterior.

[0015] In summary, this utility model has at least one of the following beneficial effects:

[0016] 1. The adjustable insulating outer tube of this utility model for superficial tumor high-frequency electrosurgical unit has an insulating material design around the electrosurgical head that can effectively isolate the current. This not only avoids the side damage to normal tissues during surgery that traditional electrosurgical units do, but also enhances the controllability and safety of the surgical operation.

[0017] 2. The insulating outer tube of this utility model is designed to be thin and the end near the electrosurgical head is designed as a pointed structure, which can reduce skin bruising when the electrosurgical head is inserted into the skin, thereby ensuring minimally invasive incision and ensuring the aesthetic appearance of the incision after surgery.

[0018] 3. The position of the insulating outer tube of this utility model can be dynamically adjusted to adapt to the surgical needs of tumors at different depths, improving the flexibility of multi-scenario applications. The diameter of the tip of the electrosurgical head gradually decreases to form a pointed structure, thereby improving the cutting accuracy and hemostasis effect in the surgery of small superficial tumors.

[0024] The following combination Figure 1-4 The present invention will be described in further detail below.

[0025] This utility model discloses a high-frequency electrosurgical unit for superficial tumors with an adjustable insulating outer tube, referring to... Figure 1 and Figure 2 The device includes a blade body 3, an electric blade head 1, and an insulating outer tube 2. The electric blade head 1 is fixedly installed inside the blade body 3, with one end extending out of the blade body 3. The insulating outer tube 2 is sleeved on the electric blade head 1 and can slide along the electric blade head 1. The blade body 3 is provided with a sliding groove 31, and a slider 21 is provided in the sliding groove 31. The slider 21 is connected to the insulating outer tube 2 and can slide in the sliding groove 31, thereby driving the insulating outer tube 2 to extend and retract. A linear slide rail 311 is provided in the sliding groove 31 along the axial direction of the electric blade head 1, and the slider 21 is located on the linear slide rail 311.

[0026] In a further implementation, refer to Figure 3 The linear slide rail 311 is provided with a micro-tooth structure 312. The slider 21 makes contact with the linear slide rail 311 through the micro-tooth structure 312. The micro-tooth structure 312 is fine to ensure that the slider 21 can be adjusted smoothly.

[0027] In a further implementation, refer to Figure 4 The diameter of the electric knife head 1 extending from the end of the knife body 3 gradually decreases in the direction away from the knife body 3, forming the tip 11 of the electric knife head. The insulating outer tube 2 is made of elastic thin-walled insulating material. The end of the insulating outer tube 2 near the tip 11 of the electric knife head is a tip structure 22 that cooperates with the tip 11 of the electric knife head, and the insulating outer tube 2 is tightly attached to the non-working part of the electric knife head 1 within its sliding range.

[0028] In a further embodiment, the end of the electric knife head 1 located inside the knife body 3 is connected to an external high-frequency power supply. Two operation buttons 32 are provided on the same side of the sliding groove 31. The operation buttons 32 are connected to the external high-frequency power supply and control its on / off state. The outside of the knife body 3 is provided with anti-slip texture to prevent the knife body 3 from slipping.

[0029] When treating superficial tumors, medical staff can adjust the slider 21 to extend or retract the insulating outer tube 2 to a suitable length according to the depth of the tumor and the needs of the surgery, so as to cover the non-working part of the electrosurgical head 1, thereby improving the controllability of the electrosurgical head. The tip structure 11 of the electrosurgical head 1 can improve the precision of the surgery and make its operation in a narrow surgical area more flexible.

[0030] Specifically, when treating small superficial tumors, medical staff can first pull the slider 21 up to the highest position to fully expose the electrosurgical head 1. Then, the tip 11 of the electrosurgical head is inserted into the skin. When the electrosurgical head 1 reaches the appropriate cutting depth, the medical staff can slide the slider 21 down to allow the tip 22 of the insulating outer tube to be inserted into the skin to cover the non-working area of ​​the electrosurgical head 1. After positioning, the medical staff can press the operation button 32 to start the high-frequency current to vaporize the tumor.
