Description

Technical Field

[0001] This utility model relates to the field of auxiliary medical devices, and in particular to an electrocautery hook that prevents burns and is easy to use. Background Technology

[0002] Electrocautery hooks are commonly used in thoracoscopic surgery, primarily for manipulating and separating internal organs, as well as for electrocoagulating and stopping bleeding in internal organs. Electrocautery hooks offer good operational stability, high safety, and strong practicality during surgery, effectively meeting the intended purposes and uses of medical personnel. (See appendix) Figure 1 The figure shows an electrocoagulation hook used in thoracoscopic surgery, including a hook head 20 and a hook body 10 connected to the hook head 20. The hook head 20 is L-shaped and cannot be retracted into the hook body 10, so the hook head 20 is exposed inside the body during the operation, which can easily burn the surrounding healthy tissue. Utility Model Content

[0003] In view of the shortcomings mentioned above in the background technology, this utility model provides an electrocoating hook that prevents burns and is easy to use.

[0004] The present invention adopts the following technical solution: An electrocautery hook for preventing burns and facilitating use, the electrocautery hook comprising: A sleeve, wherein the interior of the sleeve is hollow to form a cavity; A ceramic tube, wherein the ceramic tube is disposed at the front end of the sleeve and the interior of the ceramic tube is hollow; A hook rod is provided inside the cavity of the sleeve, and the hook rod can slide through the sleeve and the ceramic tube; The hook head includes a connecting rod, a hook-shaped blade, and an anti-collision protrusion. The rear end of the connecting rod is connected to the front end of the hook rod. The hook-shaped blade is recessed at the front end of the connecting rod. An anti-collision protrusion is provided on the side of the connecting rod near the hook-shaped blade. The anti-collision protrusion is provided corresponding to the hook-shaped blade, and the anti-collision protrusion is more prominent than the tip of the hook-shaped blade. The sleeve and the ceramic tube are both insulators, while the hook rod and the hook head are both conductors. When the hook rod slides, the hook head can expose the front end of the ceramic tube to hook tissue, or be inserted into the ceramic tube for surgical operations.

[0005] As a further improvement, the connecting rod, hook-shaped blade, and anti-collision protrusion are integrally formed.

[0006] As a further improvement, the ceramic tube is made of ceramic material.

[0007] As a further improvement, the tip of the hook-shaped knife is at a 45-degree angle.

[0008] As described above, this utility model has the following advantages compared to existing technologies: During use, the electrocoagulation hook is operated by sliding the hook rod to expose the hook head at the front end of the ceramic tube to hook tissue. The hook head, along with the hooked tissue, is then placed inside the ceramic tube for surgical procedures. The anti-collision protrusion prevents the hook from hooking the edge of the ceramic tube, ensuring the hook head can smoothly hook the tissue into the ceramic tube for surgical procedures. Hooking the tissue into the ceramic tube for surgical procedures avoids direct exposure of the surgical procedure to the body. Simultaneously, both the ceramic tube and the sleeve prevent the flow of current, providing excellent insulation, isolation, and protection. This ensures that when using the electrocoagulation hook for surgery or other procedures, the current will not be transmitted to the patient or other non-target areas through the ceramic tube and sleeve. Furthermore, the ceramic tube effectively prevents heat diffusion, maintaining safety and preventing burns during surgery, thereby improving the safety and reliability of the procedure.

[0013] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0014] As attached Figure 2 As shown, an electrocautery hook for preventing burns and facilitating use includes a sleeve 1, a ceramic tube 2, a hook rod 3, and a hook head 4.

[0015] As attached Figure 2 and Figure 4As shown, a ceramic tube 2 is positioned at the front end of the sleeve 1. The sleeve 1 is hollow, forming a cavity, while the ceramic tube 2 is hollow inside. A hook rod 3 is located within the cavity of the sleeve 1, and the hook rod 3 slidably passes through the sleeve 1 and the ceramic tube 2. A hook head 4 is located at the front end of the hook rod 3. When the electrocoagulation hook is operated, and the hook rod 3 slides within the sleeve 1 and the ceramic tube 2, the hook head 4 can be exposed at the front end of the ceramic tube 2 to hook tissue, or it can be retracted into the ceramic tube 2 for surgical procedures. Both the sleeve 1 and the ceramic tube 2 are insulators, while the hook rod 3 and the hook head 4 are conductors. The ceramic tube 2 is preferably made of ceramic, possessing excellent insulation, high-temperature resistance, wear resistance, and strength. Hooking tissue into the ceramic tube 2 for surgical procedures avoids direct exposure of the surgical procedure to the body. Simultaneously, both the ceramic tube 2 and the sleeve 1 prevent the flow of current, providing excellent insulation, isolation, and protection. This ensures that when using the electrocoagulation hook for surgery or other procedures, current will not be transmitted to the patient or other non-target areas through the ceramic tube 2 and the sleeve 1. Furthermore, the ceramic tube 2 effectively prevents heat diffusion, ensuring safety and preventing burns during surgery, thereby improving the safety and reliability of the procedure. In addition, the ceramic tube 2 can operate stably for extended periods in high-temperature environments, and is less prone to deformation or melting, ensuring the normal operation of the electrocoagulation hook while reducing the risk of damage or malfunction due to high temperatures.

[0016] It is worth mentioning that, as shown in the attached document Figure 3 and Figure 4 As shown, the hook head 4 includes a connecting rod 41, a hook-shaped blade 42, and an anti-collision protrusion 43. The rear end of the connecting rod 41 is connected to the front end of the hook rod 3, which can be achieved by resistance welding. Resistance welding refers to a method that uses the resistance heat generated by the current passing through the workpiece and the contact point as a heat source to locally heat the workpiece while applying pressure for welding. Since it does not require filler metal during welding, it is more non-toxic, environmentally friendly, and safe. Furthermore, the hook-shaped blade 42 is recessed at the front end of the connecting rod 41, and an anti-collision protrusion 43 is provided on the side of the connecting rod 41 near the hook-shaped blade 42, corresponding to the hook-shaped blade 42. When the hook head 4 is retracted into the ceramic tube 2 for surgical operations, because the anti-collision protrusion 43 protrudes more than the tip 44 of the hook-shaped blade 42, it prevents the hook-shaped blade 42 from hooking the edge of the ceramic tube 2 and being unable to retract, thus ensuring that the hook head 4 can smoothly hook tissue into the ceramic tube 2 for surgical operations. The anti-collision protrusion 43 has a gentle curve to prevent it from hooking the edge of the ceramic tube 2. A flared opening can also be formed at the front end of the ceramic tube 2 to facilitate the entry of the anti-collision protrusion 43 and the hook-shaped knife 42.

[0017] Further details are attached. Figure 3As shown, the tip 44 of the hook-shaped blade 42 is at a 45-degree angle, making it easier to hook into tissue. At the same time, the gentle curve of the hook-shaped blade 42 reduces traction and damage to surrounding tissues during surgery. During electrocoagulation hemostasis and cutting, the hook-shaped blade 42 can more precisely contact the target tissue while minimizing interference with non-target tissues. This helps reduce surgical complications and promotes postoperative recovery for patients.

[0018] Preferably, as shown in the appendix Figure 3 As shown, the connecting rod 41, hook-shaped blade 42, and anti-collision protrusion 43 are integrally formed. Specifically, the hook head 4 can be formed by casting process, which improves the strength and rigidity of the hook head 4 and ensures that the hook head 4 has better durability and reliability.

[0019] In summary, when using this invention, the electrocoagulation hook is operated by sliding the hook rod 3, exposing the hook head 4 at the front end of the ceramic tube 2 to hook tissue. The hook head 4, along with the hooked tissue, is then retracted into the ceramic tube 2 for surgical procedures. The anti-collision protrusion 43 prevents the hook-shaped blade 42 from hooking the edge of the ceramic tube 2, ensuring that the hook head 4 can smoothly hook the tissue into the ceramic tube 2 for surgical procedures. Hooking the tissue into the ceramic tube 2 for surgical procedures avoids direct exposure of the surgical procedure to the body. Simultaneously, both the ceramic tube 2 and the sleeve 1 prevent the flow of current, providing excellent insulation, isolation, and protection. This ensures that when using the electrocoagulation hook for surgery or other procedures, the current will not be transmitted to the patient or other non-target areas through the ceramic tube 2 and sleeve 1. Furthermore, the ceramic tube 2 effectively prevents heat diffusion, maintaining safety and preventing burns during surgery, thereby improving the safety and reliability of the procedure. This electrocoagulation hook is mainly used for incision of digestive scar stenosis. The hook-shaped blade 42 can gradually and progressively cut, preventing accidental excessive removal that could cause digestive tract perforation.

[0020] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
