[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a clamp head of an electrosurgical tissue closer, which includes a body 1. One side of the body 1 is connected to an outer sleeve 2. One side of the outer sleeve 2 is provided with a ceramic upper clamp head 3 and a ceramic lower clamp head 4. Inside the ceramic upper clamp head 3, there is an upper electrode plate 31. Inside the ceramic lower clamp head 4, there are a ceramic convex block 42 and a lower electrode plate 41. At the bottom of the body 1, there is a closing mechanism, which is connected to the ceramic upper clamp head 3 and the ceramic lower clamp head 4. On one side of the body 1, there is a switch button 11, and the closing mechanism corresponds to the switch button 11. At the bottom of the body 1, there is a cutting mechanism, and one side of the cutting mechanism is connected to a cutting blade 24; First, correctly install the clamp head of the electrosurgical tissue closer onto the main body of the electrosurgical instrument, ensuring that all connections are firm and error-free. Check whether the ceramic upper clamp head 3 and the ceramic lower clamp head 4 are clean and free of foreign objects, especially the surfaces of the upper electrode plate 31 and the lower electrode plate 41, to avoid unnecessary damage or contamination during the process. Place the switch button 11 in the initial position to ensure that the cutting mechanism and the closing mechanism are in an inactive state. Gently align and approach the ceramic upper clamp head 3 and the ceramic lower clamp head 4 of the clamp head of the electrosurgical tissue closer to the target tissue. Press the closing mechanism, and this action will drive the ceramic upper clamp head 3 and the ceramic lower clamp head 4 to gradually close until the target tissue is firmly clamped. The target tissue is elastic, and it can be pressed further on this basis. Continue to press the closing mechanism until the closing mechanism touches the switch button 11 on one side of the body 1. This contact action will trigger the closing of the circuit, causing current to conduct from the main body to the upper electrode plate 31 of the ceramic upper clamp head 3 and the lower electrode plate 41 of the ceramic lower clamp head 4 through the wire. The current acts directly on the clamped tissue through the electrode plates, and the electrocoagulation process begins to electrocoagulate the tissue. After confirming that the electrocoagulation is completed, press the cutting mechanism to extend the cutting blade 24 to cut the electrocoagulated tissue. After cutting is completed, release the device to allow the closing mechanism and the cutting mechanism to automatically reset. The ceramic upper clamp head 3 and the ceramic lower clamp head 4 will automatically open to release the processed tissue. And perform necessary cleaning and disinfection treatments for the next use. By providing a closing mechanism and a cutting mechanism, relevant personnel only need to press to complete the electrocoagulation and cutting of the tissue, shortening the operation time and improving the operation efficiency. By providing a ceramic upper clamp head 3 and a ceramic lower clamp head 4, the insulation performance and durability of the clamp head are improved, and the stable transmission of current during the electrocoagulation process is ensured, avoiding potential damage to surrounding tissues caused by current leakage.
[0025] The ceramic upper clamp head 3 and the ceramic lower clamp head 4 are integrated clamp heads, and there are nine ceramic convex blocks 42; the design of the integrated clamp head enhances the integrity and stability of the clamp head. During the manufacturing process of the integrated clamp head, the clamp head is tightly connected through precise processing technology to ensure that it will not separate due to external forces during use, improving the durability and reliability of the clamp head. The nine ceramic convex blocks 42 and the ceramic lower clamp head 4 are also fixedly integrated, controlling the closing gap between the upper and lower clamp heads and playing the insulation function between the upper and lower clamp heads.
[0026] Nine through-holes are provided inside the lower electrode sheet 41, and the through-holes correspond to the ceramic bumps 42; in the design of the lower electrode sheet 41, nine through-holes corresponding to the positions of the ceramic bumps 42 are specially reserved, so that the through-holes of the lower electrode sheet 41 can pass through the ceramic bumps 42, and the lower electrode sheet 41 can be attached to the ceramic lower jaw 4. The ceramic bumps 42 can block in the middle of the two electrode sheets to play a role of separation and insulation. The ceramic material itself has extremely high insulation performance, which can better play the insulation function.
[0027] The closing mechanism includes a firing handle 12, the firing handle 12 is connected to the fuselage 1, a bump 13 is fixedly connected to one side of the firing handle 12, the bump 13 corresponds to the switch button 11, a center push rod 21 is connected to one side of the firing handle 12, the center push rod 21 is inside the outer sleeve 2, the center push rod 21 is slidably connected to the outer sleeve 2, a movable closing pin 23 is connected to one side of the center push rod 21, long grooves and round grooves are provided inside both the ceramic upper jaw 3 and the ceramic lower jaw 4, the movable closing pin 23 is inside the two long grooves, and a fixing pin 22 is passed through the round groove; at the beginning, there is a certain distance between the bump 13 and the switch button 11, and the jaws remain open. Gently hold the firing handle 12, and the firing handle 12 will push the center push rod 21 forward, so that the movable closing pin 23 moves towards one end of the jaws. The ceramic lower jaw 4 and the fixing pin 22 are both fixed. The movable closing pin 23 is at the ends of the two long grooves. At the beginning, the movable closing pin 23 is pulled by the center push rod 21, and the two jaws are in an open state. When the movable closing pin 23 slides inside the long groove, it will press the long groove of the ceramic upper jaw 3 and drive the ceramic upper jaw 3 downward, so that the two jaws are combined. A spring is connected to the middle of one end of the two jaws. When combined, the spring is compressed. When retracted, the rebounding force of the spring causes the two jaws to open. By providing a closing mechanism, relevant personnel only need to press to complete the clamping of the jaws, which is simple to operate and saves manpower.
[0028] The ceramic lower jaw 4 is fixedly connected to the outer sleeve 2, and the ceramic upper jaw 3 is movably connected to the outer sleeve 2; the ceramic upper jaw 3 is rotatably connected to the outer sleeve 2, so that the ceramic upper jaw 3 can move, and the two jaws can be opened and closed relatively. The ceramic lower jaw 4 is fixed, so that there will be a certain supporting force during clamping. If both are movable, clamping cannot be achieved.
[0029] The fixing pin 22 is fixedly connected to the ceramic lower jaw 4 and rotatably connected to the ceramic upper jaw 3; both ends of the fixing pin 22 are fixedly connected to the ceramic lower jaw 4 to ensure stability, and the middle part of the fixing pin 22 is rotatably connected to the ceramic upper jaw 3 to ensure that the ceramic upper jaw 3 can move.
[0030] The cutting mechanism includes a push knife handle 14, which is connected to the fuselage 1. A moving rod is connected to one side of the push knife handle 14, and the moving rod is connected to a cutting knife 24. When the relevant personnel press the push knife handle 14, the moving rod will move towards the direction of the two clamping heads, so that the cutting knife 24 will move towards the clamped tissue part to achieve cutting.
[0031] The moving rod is slidably connected to the inside of the outer sleeve 2, which ensures better movement of the moving rod and the continuity of the operation.
[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
