Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a water injection connection channel structure for bipolar electrocoagulation forceps and a bipolar electrocoagulation forceps. Background Technology
[0002] Bipolar electrocoagulation forceps are an indispensable high-precision medical instrument in otolaryngological surgery, playing a key role in hemostasis, especially in tonsil, nasal cavity, sinus and nasopharynx surgeries. It utilizes the thermal effect principle of high-frequency current to precisely control the current applied to the surgical site, causing the blood vessel walls to dehydrate and shrink, and the blood to coagulate rapidly, thereby achieving a fast and effective hemostasis effect. It is especially suitable for surgical operations in complex and sensitive areas such as tonsils, nasal cavity, sinus and nasopharynx.
[0003] When using bipolar electrocoagulation forceps, sterile saline solution should be used as a cooling water to moisten the wound, lower the temperature during electrocoagulation, effectively prevent the forceps tip from adhering to the treated tissue, and ensure the smooth progress of the surgery. Figure 1 As shown, a water injection channel 200 is generally provided on the inner side of the forceps body 100. For example, the patent number is CN202321178713.8, and the patent name is: a utility model patent for a structure of a water injection connection channel for bipolar forceps. Physiological saline is delivered to the water injection channel 200 of the forceps body using a water injection pipe and a water distribution chamber.
[0004] However, in actual use, in order to ensure the opening or closing of the saline in the tubing, a valve needs to be added to the tubing. During the operation, the doctor opens it manually, and after the operation, the doctor needs to close the valve. The process of opening and closing the valve often requires the doctor to perform it personally. This means that during the tense operation, the doctor not only needs to concentrate on the operation itself, but also needs to pay attention to and operate the valve. This not only distracts the doctor, but may also affect the smoothness of the operation. Summary of the Invention
[0005] To address the above problems, this application provides a water injection connection channel structure for bipolar electrocoagulation tweezers, which includes a water injection shell installed between two tweezer bodies. The water injection shell has an inlet and an outlet, a plunger inside, two sealing elements on the plunger, and an elastic element inside the water injection shell.
[0006] In one embodiment, the water injection housing is a hollow cavity structure, and the plunger can reciprocate along the axial direction of the water injection housing.
[0007] In one embodiment, one end of the elastic element is connected to the inner wall of the water injection housing, and the other end is connected to the sealing element.
[0008] In one embodiment, the inlet is connected to an external water source, and the outlet is connected to the water injection channels on the two tweezers via a water distributor.
[0009] In one embodiment, the distance between the two seals is greater than the distance between the inlet and the outlet in the axial direction, and the width of a single seal is less than the distance between the inlet and the outlet in the axial direction.
[0010] In one embodiment, the seal is an annular sealing ring, and two of the seals are fixedly mounted on the plunger.
[0011] In one embodiment, the elastic element is a spring.
[0012] This utility model also provides a bipolar electrocoagulation forceps, which includes a water injection connection channel structure for bipolar electrocoagulation forceps.
[0013] The beneficial effects of this utility model are as follows:
[0014] This application discloses a water-filled connection channel structure for bipolar electrocautery tweezers. The structure includes a water-filled housing installed between two tweezer bodies. The housing has an inlet and an outlet, and contains a plunger with two seals. An elastic element is also present within the housing. Initially, due to the expansion of the elastic element, the plunger and one of its seals are pushed to the far right of the housing, placing the seal between the inlet and outlet. This seal effectively prevents water from flowing from the inlet to the outlet, effectively closing the channel. When the user presses the tweezer bodies, the plunger, under pressure, overcomes the expansion force of the elastic element and moves. As the plunger moves, the inlet and outlet are positioned between the two seals, no longer directly obstructed, creating a clear channel that allows water to flow through, providing necessary cooling or cleaning for the electrocautery tweezers. This application directly links the pressing action of the forceps with the movement of the plunger. Surgeons no longer need to manually operate valves to control the flow of saline solution during surgery; instead, this function is achieved simply by pressing or releasing the forceps. This simplifies the procedure, reduces the surgeon's workload, and allows them to focus more on the surgery itself without being distracted by operating valves. The water-filled connection channel structure of this application's bipolar electrocoagulation forceps provides surgeons with a more convenient, reliable, and efficient saline solution through automated control, improved surgical focus, and reduced human error, thereby contributing to improved surgical quality and safety.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0024] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0025] like Figure 1-5 As shown, a water injection connection channel structure for bipolar electrocoagulation tweezers includes a water injection housing 1, which is installed between two tweezer bodies 100. The water injection housing 1 has a water inlet 2 and a water outlet 3. A plunger 4 is provided in the water injection housing 1, and two sealing elements 5 are provided on the plunger 4. An elastic element 6 is provided in the water injection housing 1.
[0026] Specifically, the water injection housing 1 is positioned between the two tweezer bodies 100. The water injection housing 1 has an inlet 2 and an outlet 3, which are channels for water flow. A plunger 4 is installed inside the water injection housing 1, and it has two seals 5, whose main function is to control the flow of water. An elastic element 6 is also located inside the water injection housing 1. The elastic element 6 can be a spring and is in an expanded state. The elastic element 6 provides initial support and restoring force for the plunger 4 and its seals 5. In the initial state, due to the expansion of the elastic element 6, the plunger 4 and one of its seals 6 are pushed to the far right of the water injection housing 1. Figure 4 As shown, the seal 5 is positioned between the inlet 2 and the outlet 3. The presence of the seal 5 effectively prevents water from flowing from the inlet 2 to the outlet 3, meaning the channel is closed at this time. When the user presses the tweezers 100, the plunger 4, under pressure, overcomes the expansion force of the elastic element 6 and moves. As the plunger 4 moves, the seal 5, originally located between the inlet 2 and the outlet 3, is also moved, as shown... Figure 5 As shown, the inlet 2 and outlet 3 are located between the two seals 5, no longer directly blocked by the seals 5. A smooth channel is formed between the inlet 2 and outlet 3, allowing water to flow through. Once the channel between the inlet 2 and outlet 3 is opened, water can flow from the inlet 2 into the water-filled housing 1 and out through the outlet 3, providing the necessary cooling or cleaning function for the electrocautery tweezers. When the user releases the pressure on the tweezers, the elastic element 6 begins to reset due to its own expansion force, pushing the plunger 4 and the seals 5 on it back to the initial position. Once the seals 5 are again located between the inlet 2 and outlet 3, the water flow is blocked again. This application directly links the pressing action of the forceps 100 with the movement of the plunger 4. Doctors no longer need to manually operate the valve to control the flow of saline solution during surgery; instead, they can achieve this function simply by pressing or releasing the forceps. This simplifies the procedure, reduces the workload on doctors during surgery, and allows them to focus more on the surgery itself without being distracted by operating the valve. The bipolar electrocoagulation forceps with water-filled connection channel structure of this application provides doctors with a more convenient, reliable, and efficient saline solution through automated control, improved surgical focus, and reduced human error, thereby contributing to improved surgical quality and safety.
[0027] like Figure 4 , 5 As shown, the water injection housing 1 has a hollow cavity structure, and the plunger 4 can reciprocate along the axial direction of the water injection housing 1.
[0028] Specifically, the water injection shell 1 is a hollow cavity structure that provides a channel for water flow and provides stable support and guidance for the plunger 4. The plunger 4 moves back and forth along the axial direction of the water injection shell 1 to realize the opening and closing of the water flow.
[0029] like Figure 4 , 5 As shown, one end of the elastic element 6 is connected to the inner wall of the water injection housing 1, and the other end is connected to the sealing element 5.
[0030] Specifically, connecting one end of the elastic element 6 to the inner wall of the water injection housing 1 ensures the overall stability of the water injection connection channel structure, enabling the elastic element 6 to stably provide a reaction force when subjected to external forces. When the plunger 4 moves, the seal 5 moves accordingly, thereby opening or closing the channel between the inlet 2 and the outlet 3. The resetting action of the elastic element 6 ensures that the seal 5 can reliably return to the closed position, achieving precise control of the water flow.
[0031] like Figure 1 , 2 As shown in Figure 4, the inlet 2 is connected to an external water source, and the outlet 3 is connected to the water injection channels 200 on the two tweezer bodies 100 through a water distributor.
[0032] Specifically, the water distributor can be a three-way flexible hose, with one end connected to the water outlet 3 and the other two ends connected to the water injection channels 200 on the two forceps bodies 100. The water distributor allows the water flow from the water outlet 3 to be evenly distributed into the water injection channels 200 of the two forceps bodies 100, ensuring that when performing surgery using bipolar electrocoagulation forceps, the two forceps tips can simultaneously obtain the necessary cooling and rinsing water source, thereby keeping the surgical site moist and non-adhesive.
[0033] like Figure 4 , 5 As shown, the distance between the two seals 5 is greater than the distance between the inlet 2 and the outlet 3 in the axial direction, and the width of a single seal 5 is less than the distance between the inlet 2 and the outlet 3 in the axial direction.
[0034] Specifically, the distance between the two seals 5 is greater than the distance between the inlet 2 and the outlet 3 in the axial direction. That is, when the plunger 4 moves to the leftmost position, the inlet 2 and the outlet 3 are located between the two seals 5, so that water can flow. The width of a single seal 5 is smaller than the distance between the inlet 2 and the outlet 3 in the axial direction. By precisely setting the distance between the two seals 5 and the width of a single seal 5, precise control of the water flow can be achieved, and a stable and appropriate amount of water flow can be obtained.
[0035] like Figure 4 , 5 As shown, the sealing element 5 is an annular sealing ring, and two sealing elements 5 are fixedly installed on the plunger 4.
[0036] Specifically, the seal 5 is designed as an annular sealing ring, which ensures that the seal 5 can fit tightly against the inner wall of the water injection housing 1 during the movement of the plunger 4, thereby effectively preventing water from passing through when not needed. The fixedly installed seal 5 can reduce shaking or displacement during the movement of the plunger 4, thereby improving the stability of the entire water injection connection channel structure.
[0037] This application discloses a water injection connection channel structure for bipolar electrocoagulation tweezers, comprising a water injection housing 1 installed between two tweezer bodies 100. The water injection housing 1 has an inlet 2 and an outlet 3. A plunger 4 is disposed within the water injection housing 1, and two sealing elements 5 are disposed on the plunger 4. An elastic element 6 is disposed within the water injection housing 1. In the initial state, due to the expansion effect of the elastic element 6, the plunger 4 and one of the sealing elements 6 are pushed to the rightmost side of the water injection housing 1, so that the sealing element 5 is located between the inlet 2 and the outlet 3. The presence of the sealing element 5 effectively prevents water from flowing from the inlet 2 to the outlet 3, that is, the channel is closed at this time. When the user presses the forceps body 100, the plunger 4, under pressure, overcomes the expansion force of the elastic element 6 and moves. As the plunger 4 moves, the inlet 2 and outlet 3 are located between the two seals 5, no longer directly blocked by them. A smooth channel is formed between the inlet 2 and outlet 3, allowing water to flow through and providing the necessary cooling or cleaning function for the electrocoagulation forceps. This application directly links the pressing action of the forceps body 100 with the movement of the plunger 4. Doctors no longer need to manually operate the valve to control the flow of saline solution during surgery; instead, this function is achieved simply by pressing or releasing the forceps body. This simplifies the operation process, reduces the doctor's workload during surgery, and allows them to focus more on the surgery itself without being distracted by operating the valve. The water-filled connection channel structure of this application's bipolar electrocoagulation forceps provides doctors with a more convenient, reliable, and efficient saline solution through automated control, improved surgical focus, and reduced human error, thereby helping to improve surgical quality and safety.
