Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bipolar electrocoagulation gripper with a turning function for use in laparoscopic surgery. Background Technology

[0002] Bipolar electrocoagulation grasping forceps are a widely used medical instrument in laparoscopic surgery, primarily for hemostasis and tissue management. It uses the heat generated by a high-frequency current to coagulate the tissue, thereby achieving hemostasis. The design of this instrument ensures that the current flows only within the tissue between the two electrodes, reducing thermal damage to surrounding tissues and improving surgical safety.

[0003] The working principle of bipolar electrocoagulation grasping forceps is based on the thermal effect of electric current. When an electric current passes through the tissue between the two electrodes, the water in the tissue evaporates rapidly, causing the proteins within the cells to coagulate, thereby achieving hemostasis. This device typically has a precise control mechanism that allows adjustment of the intensity and duration of the current to accommodate different types and sizes of blood vessels.

[0004] Traditional electrocoagulation grasping forceps lack effective markings during turning operations. During surgery, surgeons struggle to precisely control the turning angle and direction of the forceps. Without visual markings to indicate the degree of turning, surgeons often rely on experience, which can easily lead to errors in complex laparoscopic surgical environments. For example, the forceps may be over- or under-adjusted, affecting the accurate grasping or handling of tissue and increasing surgical risks. Therefore, a bipolar electrocoagulation grasping forceps with turning capabilities for laparoscopic surgery is proposed to address these issues. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a bipolar electrocoagulation grasping forceps with turning function for laparoscopic surgery, aiming to improve the problem caused by the lack of an effective marking system when the electrocoagulation grasping forceps are turned in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bipolar electrocoagulation grasping forceps with a turning function for laparoscopic surgery includes a handle, a rotating wheel rotatably connected to the outside of the handle, a turning marking ring fixedly connected to the outside of the handle, the turning marking ring having a scale on its outside, the rotating wheel and the rotating wheel both having markings on their outside, a turning adjustment wheel rotatably connected to the outside of the handle, a lead screw detachably connected inside the turning adjustment wheel, a top block fixedly connected to the left end of the lead screw, a spring plate fixedly connected to the left side of the top block, an electrode provided at the top of the handle, and a positioning component fixedly connected inside the rotating wheel to facilitate the positioning and installation of the bipolar electrocoagulation grasping forceps;

[0008] As a further description of the above technical solution:

[0009] The positioning component includes a support rod, the right end of which is fixedly connected to the inside of the rotating wheel, the right end of the lead screw is rotatably connected to the inner wall of the support rod, a slot is provided on the left side of the support rod, a positioning block is detachably connected to the inner wall of the slot, a round block is fixedly connected to the left side of the positioning block, a clamp rod is fixedly connected to the left side of the round block, and a clamp head is fixedly connected to the left end of the clamp rod.

[0010] As a further description of the above technical solution:

[0011] The clamp bar is fitted with a tightening cap, the right side of which is threaded to the left side of the support rod, and the right side of the tightening cap is in contact with the left side of the turning adjustment wheel;

[0016] As a further description of the above technical solution:

[0017] The width of the turning mark ring is 10mm, and the width of the mark is 1.5mm.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this invention, rotating the turning adjustment wheel drives the lead screw to move left and right, which in turn moves the top block left and right, pressing against the spring plate to bend it. Then, rotating the wheel drives the forceps bar and forceps head to rotate, achieving the turning function. When the wheel rotates, the markings and scales correspond. This allows the surgeon to precisely control the rotation angle of the wheel based on the correspondence between the markings and scales, thereby accurately adjusting the turning direction of the forceps head. This enables the surgeon to precisely control the forceps' movements in scenarios requiring delicate manipulation, such as laparoscopic surgery, improving the success rate of the surgery.

[0020] 2. In this utility model, the clamp bar and the rotating wheel are detachably connected, which facilitates the installation and maintenance of the clamp bar. For example, when it is necessary to clean, repair, or replace the clamp bar, it can be easily operated. At the same time, the positioning block ensures that the clamp bar can only be installed in the corresponding position each time, so that the clamp bar and the rotating wheel are installed in the same position each time, which helps to ensure the operational stability of the entire bipolar electrocoagulation gripper.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a bipolar electrocoagulation grasping forceps with a turning function for laparoscopic surgery. The forceps includes a handle 1, which is the foundation of the entire forceps, providing the basis for the installation and operation of other components. Its shape and design conform to ergonomic principles, making it easy for doctors to hold. In scenarios requiring delicate operations, such as laparoscopic surgery, a well-designed handle can reduce hand fatigue and improve the stability and accuracy of the operation. A rotating wheel 2 is rotatably connected to the outside of the handle 1, playing an important role in transmission and positioning within the entire device. This rotatable connection allows the wheel 2 to rotate flexibly on the handle 1. A turning marking ring 3 is fixedly connected to the outside of the handle 1, serving as a crucial component for marking the turning function. The turning marking ring 3 is 10mm wide, with its right side contacting the left side of the wheel 2. The outside of the turning marking ring 3 is provided with scales 4. Both the wheel 2 and the rotating wheel 2 are provided with markings 5, each 1.5mm wide. Mark 5 is matched with the scale 4 on the turning mark ring 3. When the wheel 2 rotates, mark 5 will move with the rotation of the wheel 2 and correspond to scale 4, so that the turning function has a clear turning direction. This helps doctors to accurately control the angle and other parameters of the turning operation.

[0029] A turning adjustment wheel 6 is externally rotatably connected to the handle 1. The turning adjustment wheel 6 is a key component for adjusting the turning function of the bipolar electrocoagulation forceps. The right side of the turning adjustment wheel 6 contacts the left side of the turning marking ring 3. A lead screw 7 is internally rotatably connected to the turning adjustment wheel 6. When the turning adjustment wheel 6 is rotated, it drives the lead screw 7 to move left and right. A top block 8 is fixedly connected to the left end of the lead screw 7. During the turning function, the lead screw 7 acts as a transmission and drive, converting the rotation of the turning adjustment wheel 6 into its own left and right movement, which in turn drives the top block 8 to move left and right. A spring plate 9 is fixedly connected to the left side of the top block 8. When the top block 8 moves left and right, it presses against the spring plate 9, causing the spring plate 9 to deform and bend, thus achieving the turning function. An electrode 13 is located at the top of the handle 1. The electrode 13 plays a crucial role in the electrocoagulation function of the bipolar electrocoagulation forceps. In laparoscopic surgery, the electrode 13 can perform electrocoagulation operations on tissue through appropriate current conduction, such as hemostasis.

[0030] Reference Figure 1 , Figure 3 and Figure 4The rotating wheel 2 has a fixed internal positioning component for easy positioning and installation of the bipolar electrocoagulation forceps. The positioning component includes a support rod 12, the right end of which is fixedly connected to the inside of the rotating wheel 2. The right end of the lead screw 7 is rotatably connected to the inner wall of the support rod 12. The support rod 12 supports the rotation of the lead screw 7. A slot 13 is provided on the left side of the support rod 12, and a positioning block 14 is detachably connected to the inner wall of the slot 13. The slot 13 and the positioning block 14 cooperate to ensure that the installation position remains the same each time. A round block 15 is fixedly connected to the left side of the positioning block 14, and a forceps bar 10 is fixedly connected to the left side of the round block 15. This detachable connection facilitates the installation and maintenance of the forceps bar 10. A forceps head 11 is fixedly connected to the left end of the forceps bar 10. This is the part of the bipolar electrocoagulation forceps that directly contacts the surgical object. When the rotating wheel 2 drives the clamp bar 10 to rotate, the clamp head 11 also rotates accordingly, thus achieving a turning function. This allows for flexible adjustment of direction during surgery, facilitating the surgeon's grasping and manipulation of tissues. A tightening cap 16 is fitted over the clamp bar 10. The right side of the tightening cap 16 is threaded to the left side of the support rod 12, and the right side of the tightening cap 16 contacts the left side of the turning adjustment wheel 6. By rotating the left side of the support rod 12, the tightening cap 16 presses the round block 15 against the support rod 12, thus completing the installation and fixation of the clamp bar 10. This ensures that the clamp bar 10 and the rotating wheel 2 are always installed in the same position, contributing to the stability and accuracy of the entire bipolar electrocoagulation grasping forceps operation. The outer wall of the top block 8 contacts the inner wall of the clamp bar 10, the outer wall of the spring plate 9 contacts the inner wall of the clamp bar 10, and the right side of the round block 15 contacts the left side of the support rod 12.

[0031] Working principle: First, rotating the turning adjustment wheel 6 drives the lead screw 7 to move left and right, which in turn drives the top block 8 to move left and right. The top block 8 then presses against the spring plate 9. Due to the gap inside the spring plate 9, the spring plate 9 will deform and bend. Then, rotating the rotating wheel 2 drives the forceps bar 10 and the forceps head 11 to rotate, thus realizing the turning function and increasing the operating space of the forceps during surgery. At the same time, when the rotating wheel 2 rotates, the mark 5 on the rotating wheel 2 will match the scale 4 on the turning mark ring 3, so that the turning function has a clear direction of rotation, which makes it easier for doctors to use instruments clearly and operate with precision.

[0032] Because the clamp bar 10 on the double-click electrocoagulation gripper can be disassembled, the positioning block 12 set inside the rotating wheel 2 ensures that the clamp bar 10 can only be installed in the rotating wheel 2 at the corresponding position, thus ensuring that the clamp bar 10 and the rotating wheel 2 are installed in the same position each time.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
