Description

Technical Field

[0001] This utility model relates to a medical device, specifically a bipolar electrocoagulation forceps. Background Technology

[0002] Since its clinical application in the mid-20th century, bipolar electrocoagulation technology has become an indispensable hemostatic tool in modern surgery. Its working principle involves using an electric current between two electrodes to denature tissue proteins, achieving hemostasis. Compared to monopolar electrocoagulation, bipolar systems offer advantages such as controllable current paths and smaller tissue damage areas, making them particularly suitable for delicate surgical fields such as neurosurgery and microsurgery. However, with the development of minimally invasive surgery and precision medicine, traditional bipolar electrocoagulation forceps have gradually revealed significant shortcomings in smoke extraction and aspiration. Most existing aspiration and aspiration systems employ a single mixing channel design, but the mixture of smoke and liquid forms an aerosol, reducing suction efficiency. Simultaneously, viscous liquids such as blood easily deposit and clog the channel, affecting aspiration efficiency. Therefore, a bipolar electrocoagulation forceps is needed. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the background art and provide a bipolar electrocoagulation clamp.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A bipolar electrocoagulation forceps includes a forceps head, a sliding rod, a sleeve, a handle, and a fixing tube. The end of the sleeve is disposed inside the handle, and the sliding rod is slidably disposed inside the sleeve. The forceps head includes two jaws and is located at the front end of the sleeve. The sliding rod controls the opening and closing of the two jaws by sliding back and forth. A suction channel is formed between the sleeve and the sliding rod. The fixing tube is disposed outside the sleeve, and a smoke extraction channel is formed between the fixing tube and the sleeve.

[0005] This invention uses a suction channel for suction and a smoke extraction channel for smoke extraction, allowing for separate processing of these two processes. During use, the independent smoke extraction channel prioritizes the removal of smoke, while accumulated blood and exudate can be cleared as needed through the suction channel. This maintains a clear surgical field of vision, improves surgical speed and efficiency, and prevents the formation of aerosols from the mixing of smoke and liquid in a single mixed channel, which would reduce suction efficiency. Additionally, viscous liquids such as blood can easily accumulate and clog the channel, affecting smoke extraction efficiency.

[0006] Preferably, the handle is provided with a three-way valve, which is divided into an inlet, a liquid outlet, and a smoke outlet. The liquid suction channel and the smoke suction channel are both connected to the inlet of the three-way valve. The control handle of the three-way valve is located on the outside of the handle, and the control handle controls whether the inlet and the liquid outlet are connected to the smoke outlet.

[0007] Preferably, a piston seal is provided between the end of the sleeve and the sliding rod. The piston seal includes a sliding block and a sealing ring. The sliding block is located at the end of the sleeve and fixed on the side wall of the sliding rod. The outer side wall of the sliding block has three or more sealing grooves along the circumferential direction. The sealing ring is located in the sealing grooves to ensure that the sliding rod can move while preventing liquid leakage. The piston seal is always inside the sleeve.

[0008] Preferably, a lighting lamp is fixed to the front end of the fixation tube. The lighting lamp illuminates the surgical area, avoiding the problem of external light source obstruction, ensuring clear visibility of deep or narrow surgical fields, and improving surgical accuracy.

[0009] Preferably, the width of the clamps gradually decreases along the direction from the bottom to the head. The smaller the width of the clamp in this invention, the higher the current density, the more concentrated the energy generated, and the faster the temperature rises, thereby achieving high efficiency in electrocoagulation.

[0010] Preferably, the opposing sides of the two jaws are provided with interlocking teeth to prevent slippage during clamping.

[0011] Preferably, the front end of the sleeve is provided with two symmetrical extension plates, and the two jaws are hinged by a fixing pin. The front end of one jaw is hinged to the front end of the sliding rod by a fixing pin, and the other jaw is hinged to the extension plate by a fixing pin, so that the opening and closing of the jaw head can be controlled by the forward and backward movement of the sliding rod.

[0012] Preferably, the handle is provided with a forward and backward movement control mechanism, which includes a hand-held part and a fixing block. The top of the hand-held part is provided with a fixing hole, and the fixing block is rotatably disposed in the fixing hole. The side wall of the hand-held part near the sliding rod is provided with a limiting groove to facilitate the sliding rod to pass through and move forward and backward. The end of the sliding rod is disposed in the fixing block. The part of the hand-held part located inside the handle is provided with a support shaft to facilitate the rotation of the hand-held part. The hand-held part and the handle are scissor-shaped. The sleeve is limited on the handle and will not move forward and backward, but can only rotate. In this invention, when the hand-held part rotates along the support shaft, the sleeve will not move forward and backward, thereby allowing the sliding rod to move forward and backward.

[0013] Preferably, a rotating ring is fixed to the end of the fixing tube, the fixing tube and the rotating ring are interconnected, the rotating ring and the sleeve are fixedly connected by fixing strips, a smoking hole is formed between the two fixing strips, and the end of the rotating ring is sealed to the sleeve to prevent smoke leakage. This utility model can drive the forceps head to rotate by rotating the rotating ring, which can accurately adapt to complex surgical fields, stop bleeding at multiple angles, reduce instrument changes and tissue traction, improve electrocoagulation effect, reduce the risk of thermal damage, optimize operation efficiency, and enhance surgical safety. It is especially suitable for minimally invasive and narrow space operations.

[0014] Preferably, a limiting ring is formed at the end of the sliding rod, and a groove is formed on the fixing block to prevent the limiting ring from moving back and forth. The limiting ring can ensure the rotation of the sliding rod and prevent the sliding rod from falling off the fixing block.

[0015] In summary, the beneficial effects of this utility model are as follows: 1. This utility model uses a suction channel for suction and a smoke extraction channel for smoke extraction, allowing for separate processing of suction and smoke extraction. During use, the independent smoke extraction channel can prioritize the processing of smoke, while blood and exudate can be removed as needed through the suction channel, thereby maintaining a clear surgical field of vision, improving surgical speed and efficiency, and preventing the formation of aerosols when smoke and liquid mix in a single mixing channel, which would reduce suction efficiency. At the same time, viscous liquids such as blood are prone to deposit and block the channel, affecting smoke extraction efficiency. 2. Illuminate the surgical area with a lighting lamp to avoid obstruction by external light sources, ensuring clear visibility of deep or narrow surgical fields and improving surgical precision; 3. This utility model can drive the forceps head to rotate by rotating the rotating ring, which can accurately adapt to complex surgical fields, stop bleeding from multiple angles, optimize operation efficiency, and enhance surgical safety. It is especially suitable for minimally invasive and narrow space operations. Attached Figure Description

[0021] like Figure 4 As shown, the handle 4 is provided with a three-way valve 41, which is divided into an inlet 411, a liquid outlet 412 and a smoke outlet 413. The liquid suction channel 6 and the smoke suction channel 60 are both connected to the inlet of the three-way valve 41. The control handle of the three-way valve 41 is located on the outside of the handle 4.

[0022] like Figure 11 As shown, a piston seal 42 is provided between the end of the sleeve 3 and the sliding rod 2. The piston seal 42 includes a sliding block 421 and a sealing ring 422. The sliding block 421 is located at the end of the sleeve 3 and fixed on the side wall of the sliding rod 2. The outer side wall of the sliding block 421 is provided with three or more sealing grooves 423 along the circumferential direction. The sealing ring 422 is disposed in the sealing groove 423.

[0023] like Figure 2 As shown, a lighting lamp 5 is fixed to the front end of the fixing tube 30, and the width of the jaws 11 gradually decreases along the direction from the bottom to the head. The opposing sides of the two jaws 11 are provided with interlocking teeth 110.

[0024] like Figure 2-3 As shown, the front end of the sleeve 3 is provided with two symmetrical extension plates 31, and the two jaws 11 are hinged by a fixing pin. The front end of one jaw 11 is hinged to the front end of the sliding rod 2 by a fixing pin, and the other jaw 11 is hinged to the extension plate 31 by a fixing pin.

[0025] like Figure 4-6 As shown, the handle 4 is provided with a forward and backward movement control mechanism 40. The forward and backward movement control mechanism 40 includes a hand-held part 401 and a fixing block 402. The top of the hand-held part 401 is provided with a fixing hole 403. The fixing block 402 is rotatably disposed in the fixing hole 403. The side wall of the hand-held part 401 near the sliding rod 2 is provided with a limiting groove 404 to facilitate the sliding rod 2 to pass through and move forward and backward. The end of the sliding rod 2 is disposed in the fixing block 402. The part of the hand-held part 401 located inside the handle is provided with a support shaft 405 to facilitate the rotation of the hand-held part 401. The end of the fixing tube 30 is fixed with a rotating ring 32. The fixing tube 30 and the rotating ring 32 are interconnected.

[0026] Working principle: such as Figure 1-11 As shown, during use, the handheld part 401 is opened, the sliding rod 2 moves forward to open the forceps head 1, the handheld part 401 is closed, and the sliding rod 2 moves backward to close the forceps head 1, thereby performing electrocoagulation and electrocautery. During the operation, when smoking is required, the three-way valve 41 rotates to connect the smoking channel 60 and the smoke outlet 413. When suction is required, the three-way valve 41 rotates to connect the suction channel 6 and the liquid outlet 412, improving the speed and efficiency of the operation. This prevents the formation of aerosols after the smoke and liquid are mixed in a single mixing channel, which would reduce the suction efficiency. At the same time, viscous liquids such as blood are prone to deposit and block the channel, affecting the smoking efficiency.
