Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a bendable pen-holding obtuse-angle electrocoagulation hook. Background Technology

[0002] Electrocoagulation hooks are surgical consumables commonly used in minimally invasive laparoscopic surgeries in major hospitals, including thoracic surgery, general surgery, urology, minimally invasive surgery, and gynecology. They are used for tissue separation, hemostasis, and cutting during laparoscopic surgery, exhibiting good operational stability, safety, and practicality. By using electrocoagulation hooks, medical personnel can safely perform tissue separation, hemostasis, and cutting during laparoscopic surgery.

[0003] However, in some special locations or when there are adhesions in the chest cavity, a straight electrocautery hook is difficult to deploy effectively, posing some application difficulties. In such cases, a specialized bent electrocautery hook must be used instead. Secondly, most electrocautery hooks are currently foot-controlled, requiring foot strength and movement for control during surgery. Their precision cannot match that of hand strength and movement. There are also issues such as the trigger switch shifting on the ground, requiring passive searching for the switch position before firing, making them inconvenient to use. Finally, most electrocautery hooks currently have a right-angle design. In actual operation, in most cases, only a small part of the hook head needs to hook the tissue. The right-angle design is sometimes less convenient to use in special locations or tissues due to the angle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a bendable pen-holding obtuse-angle electrocoating hook, which is easy to operate and has an adjustable length.

[0005] This utility model provides a bendable pen-holding obtuse-angle electrocoating hook, including an inner sleeve with a conductive post inside, the conductive post being made of high-quality stainless steel. A clamp is threaded onto the end of the inner sleeve, the clamp being shaped with one end having a larger diameter and the other a smaller diameter. An electric hook is installed in the middle of the clamp. A conductive seat is fixed inside the clamp, and both the conductive seat and the clamp have mounting holes in their middle portions. A locking sleeve is threaded onto the smaller end of the clamp. The head of the electric hook is set at an obtuse angle of 110° or 100°. An outer sleeve is fitted over the surface of the inner sleeve, and a positioning component is provided at the head of the outer sleeve.

[0006] This invention, by adopting the above-mentioned structure, changes the internal material of the current linear electrocoagulation hook to high-quality stainless steel. High-quality stainless steel is sturdy and durable, with a certain degree of elasticity and hardness. During surgery, the bending angle can be freely and controllably adjusted according to the actual situation, which is beneficial for operation. It can be used for a long time and is not easily damaged. The traditional electrocoagulation hook is changed from a foot-controlled type to a hand-controlled pen-like type, which allows for precise surgery by relying on the dexterity of the fingers and wrist, avoiding many drawbacks of foot use. The head of the electrocoagulation hook is improved from a right angle to an obtuse angle, making it more convenient to use in special areas or tissues. At the same time, the length of the entire electrocoagulation hook can be adjusted by using the sliding fit of the outer and inner sleeves, and the length of the hook can also be flexibly adjusted according to the actual operation.

[0007] In one possible implementation, the head of the conductive post is provided with a receiving groove corresponding to the electric hook.

[0008] In one possible implementation, the tail of the conductive post is connected to a wire, and the outer surface of the inner sleeve is provided with an electrocoagulation switch.

[0009] In one possible implementation, the surface of the outer tube is provided with a through groove corresponding to the position of the electrocoagulation switch, and a handle is fixedly provided at the tail of the outer tube.

[0010] In one possible implementation, a mounting base is fixedly provided on the surface of the head of the outer sleeve, a threaded seat is fixedly provided in the middle of the mounting base, a positioning bolt is provided in the internal thread of the threaded seat, and a through hole corresponding to the positioning bolt is provided on the inner side of the outer sleeve.

[0011] In one possible implementation, the end of the clamp with a larger diameter is provided with an external thread, and the inner side of the inner sleeve head is provided with an internal thread, and the internal thread is threadedly connected to the external thread.

[0012] In one possible implementation, the end of the clamp with the smaller diameter is provided with an external thread two, and the inner side of the locking sleeve is provided with an internal thread two, which is threadedly connected to the external thread two. Attached Figure Description

[0025] See Figure 1-6As shown in the embodiment of this application, a bendable pen-grip type obtuse-angle electrocautery hook is disclosed, including an inner sleeve 1. The inner sleeve 1 has a conductive post 101 inside, which is made of high-quality stainless steel. High-quality stainless steel is sturdy and durable, with a certain degree of elasticity and hardness. During surgery, the bending angle can be freely and controllably adjusted according to the actual situation, facilitating operation. It can be used for a long time without easily being damaged. A clamp 2 is threaded at the end of the inner sleeve 1. The clamp 2 is shaped with one end having a larger diameter and the other end having a smaller diameter. An electric hook 3 is installed in the middle of the clamp 2, and a conductive seat 201 is fixedly installed inside the clamp 2. The conductive base 201 and the clamp 2 are provided with a mounting hole 202 in the middle, and a locking sleeve 205 is threaded on the smaller end of the clamp 2. The electric hook 3 is firmly held in the middle by the threaded engagement of the locking sleeve 205 and the clamp 2. The head of the electric hook 3 is set with an obtuse angle, which is 110° or 100°. In special parts or tissues, the angle is more convenient than a right angle. The inner sleeve 1 is fitted with an outer sleeve 4. The head of the outer sleeve 4 is provided with a positioning component to limit the position of the outer sleeve 4 and adjust the length for more flexible use.

[0026] See you again Figure 4 As shown, the head of the conductive post 101 is provided with a receiving groove 102 corresponding to the electric hook 3, which does not interfere with the adjustment of the position of the electric hook 3;

[0027] See you again Figure 2 As shown, the tail of the conductive post 101 is connected to a wire 105 for power connection, and the outer surface of the inner sleeve 1 is provided with an electrocoagulation switch 104 for controlling the operation of the electrocoagulation hook.

[0028] See you again Figure 2 As shown, the surface of the outer tube 4 is provided with a through groove 401 corresponding to the position of the electrocoagulation switch 104, which does not interfere with the relative movement between the outer tube 4 and the inner tube 1. The tail of the outer tube 4 is fixedly provided with a handle 402, which facilitates the operation of the outer tube 4 and the inner tube 1.

[0029] See you again Figure 6 As shown, a mounting base 403 is fixedly provided on the surface of the head of the outer sleeve 4, and a threaded seat 404 is fixedly provided in the middle of the mounting base 403. A positioning bolt 405 is provided in the internal thread of the threaded seat 404. A through hole 406 corresponding to the positioning bolt 405 is provided on the inner side of the outer sleeve 4. By tightening the positioning bolt 405, the inner sleeve 1 is clamped by the threaded engagement between the positioning bolt 405 and the threaded seat 404, thereby limiting the position of the outer sleeve 4.

[0030] See you again Figure 5As shown, the end of the clamp 2 with a larger diameter is provided with an external thread 203, and the inner side of the head of the inner sleeve 1 is provided with an internal thread 103. The internal thread 103 is threadedly connected to the external thread 203, which limits the position of the clamp 2 and facilitates disassembly and assembly.

[0031] See you again Figure 5 As shown, the end of the clamp 2 with a smaller diameter is provided with an external thread 204, and the inner side of the locking sleeve 205 is provided with an internal thread 2. The internal thread 2 is threadedly connected to the external thread 204. The position of the electric hook 3 inside the clamp 2 is clamped and limited by the thread engagement of the locking sleeve 205.

[0032] In use, first install the electric hook 3 into the middle of the clamp 2, extending the head of the electric hook 3 to the corresponding position, and tighten the locking sleeve 205 to limit the position of the electric hook 3. Then, thread the larger diameter end of the clamp 2 onto the head of the inner sleeve 1, thus completing the installation of the clamp 2 and the electric hook 3. Next, loosen the positioning bolt 405, adjust the position between the outer sleeve 4 and the inner sleeve 1, and adjust the length of the electric hook. After adjustment, tighten the positioning bolt 405 again. Use the threaded engagement between the positioning bolt 405 and the threaded seat 404 to position the inner sleeve 1, and use the friction between the two to limit the position of the outer sleeve 4.

[0033] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
