Description

Technical Field

[0001] The utility model relates to the field of medical devices, and particularly to a bipolar coagulation forceps which is convenient to operate. Background Art

[0002] The bipolar coagulation forceps consists of a double-lobe forceps body and an electrode base. The tails of the double-lobe forceps body are respectively connected to the electrode base. A high-frequency input plug is provided on the electrode base, which can perform more delicate electrocoagulation hemostasis and treatment on small blood vessels and other structures. The principle is to coagulate proteins by heating to close blood vessels.

[0003] According to the disclosed patent CN219147894U, a bipolar coagulation forceps which is convenient to operate includes an electrode base and two forceps handles symmetrically distributed on one side of the electrode base. The distal ends of the forceps handles are fixedly connected with electrocoagulation forceps rods. Fixing plates are fixedly connected to the sides of the two forceps handles for holding. A through groove is formed in the center of one of the fixing plates, and the other fixing plate is fixedly connected with a clamping plate made of an elastic material and passing through the through groove. The outside of the clamping plate is fixedly connected with equally spaced vertical teeth, and a clamping bar matching the teeth is fixedly connected to the inside of the through groove. During the operation by a doctor, the index finger and the thumb pinch the forceps handles forcefully, so that the tip of the electrocoagulation forceps rod clamps the surgical site. At the same time, the clamping plate moves relative to the through groove, and the teeth are stuck outside the clamping bar, so that the clamping plate limits the relative positions of the two fixing plates, thereby limiting the forceps handles and the electrocoagulation forceps rods, making the electrocoagulation forceps rod continuously clamp the surgical site, ensuring the clamping force. And at this time, the index finger and the thumb do not need to exert force any more, reducing the muscle fatigue of the doctor's fingers. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. By arranging a clamping plate and a fixing plate on the side between the two groups of forceps handles, the problem that medical staff need to continuously provide a clamping force for the forceps handles during the operation is solved. However, during the use process, only the unilateral limit treatment is carried out on the two groups of forceps handles in the above patent. Such a limiting method not only provides insufficient stability required for the forceps handles during use, but also cannot quickly adjust the clamping distance between the forceps handles subsequently, thus affecting the repeated use of the bipolar coagulation forceps. Therefore, a new technical solution needs to be designed to solve this problem. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a bipolar coagulation forceps which is convenient to operate, so as to solve the technical problems of insufficient stability in limiting the forceps handles and inability to quickly adjust the distance between the forceps handles multiple times, which affects the normal repeated use of the bipolar coagulation forceps.

[0005] To achieve the object of the present utility model, the technical solution adopted by the present utility model is: to design a bipolar electrocoagulation forceps that is convenient to operate, including a motor connection seat, both ends of the side of the motor connection seat are movably installed with forceps handles, each of the forceps handles is internally provided with a fixing groove, and a hollow tube is slidably inserted between the inner sides of the two groups of fixing grooves;

[0006] Both ends of the outer side of the hollow tube are movably attached with limit clamping plates, and the limit clamping plates are located inside the fixing grooves. Both ends of the side of the hollow tube are horizontally penetrated and slidably installed with push rods. Both ends of the inner side of the hollow tube are slidably installed with push plates. On the surface of each push plate close to the push rod, a push block is fixedly installed, and the top end of the side of the push rod is fixedly connected to the side of the push block;

[0007] At both ends of the side of each limit clamping plate close to the hollow tube, a transmission rod is vertically fixedly installed, and the transmission rod is slidably inserted through the inner side of the side of the hollow tube. On the surface of each transmission rod far from the limit clamping plate, a transmission block is fixedly installed, and the transmission block is located on both outer sides of the push block;

[0008] A push spring is movably sleeved in the middle of the hollow tube, and both ends of the side of the push spring are fixedly connected to the outer sides of the push plates. A return spring is movably sleeved on the outer surface of each transmission rod, and both outer sides of the return spring are respectively movably attached to the transmission block and the inner wall of the hollow tube.

[0009] Sliding grooves are respectively opened in the middle of both ends of the outer side of the hollow tube, and the push rods are slidably inserted through the sliding grooves.

[0010] Preferably, movable grooves are respectively opened at both ends of the outer side of the hollow tube, and the transmission rods are slidably inserted through the movable grooves.

[0011] Preferably, an anti-slip friction pad is fixedly inlaid on the side of each limit clamping plate far from the hollow tube, and the outer side of the anti-slip friction pad is located inside the fixing groove.

[0012] Preferably, guide blocks are fixedly installed on the surfaces of both ends of the outer side of each push plate. Guide grooves are respectively opened on both sides of the inner part of the hollow tube, and the guide blocks are slidably inserted through the guide grooves.

[0013] Preferably, a hand push sleeve is fixedly sleeved on the side of each push rod far from the hollow tube, and the hand push sleeve is located outside the hollow tube.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. The utility model fixes the hollow tube into the quick fixing grooves inside the two sets of forceps handles, and sets limit clamping plates on both sides of the outside of the hollow tube. Under the interaction of the pushing block and the transmission block, when the distance between the forceps handles needs to be adjusted, medical staff only need to use the thumb and index finger to push the pushing rods located on both sides of the hollow tube, so that the pushing block and the pushing plate move relatively synchronously. After that, the inclined surfaces of the pushing block and the transmission block are separated, and the pushing block loses the pushing force on the transmission block. Then, under the reverse pushing action of the return spring, the limit clamping plate can be driven to restore its position under the transmission action of the transmission rod and separated from the inner wall of the fixing groove, so that the limit clamping plate loses the pushing and limiting force on the forceps handle. Then, medical staff only need to use the tiger's mouth position of the palm to push both sides of the forceps handle to quickly adjust the distance between the two sets of forceps handles, which is convenient for adjusting the distance between the forceps handles and fixing the two sets of forceps handles by pushing, avoiding any shaking and affecting the surgical quality.

[0016] 2. The utility model is provided with a pushing spring between the outsides of the pushing plates. After pushing the pushing rods to separate the pushing block and the transmission block and completing the adjustment of the distance between the forceps handles, when medical staff need to re-limit and fix the forceps handles, they only need to release the pushing of the pushing rods. Then, under the reverse pushing action of the pushing spring, the pushing plate and the pushing block can be restored to their original positions. After that, the pushing block presses against the transmission block again, and the transmission block and the limit clamping plate are restored to their original positions synchronously, so that the outside of the limit clamping plate can fit inside the fixing groove to push and limit the forceps handle, avoiding any shaking during use and reducing the surgical safety of medical staff.

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] Embodiment 1: A bipolar coagulation forceps convenient for operation. Refer to Figures 1 to 4 , both ends of the side of the motor connection seat 1 are movably installed with forceps handles 11. Each forceps handle 11 is internally provided with a fixing groove 12. A hollow tube 13 is slidably inserted between the inner sides of the two groups of fixing grooves 12. Both ends of the outer side of the hollow tube 13 are movably attached to a limit clamping plate 2, and the limit clamping plate 2 is located inside the fixing groove 12. Both ends of the side of the hollow tube 13 are horizontally penetrated and slidably installed with a push rod 22. Both ends of the inner side of the hollow tube 13 are slidably installed with a push plate 21. On the surface of each push plate 21 close to the push rod 22, a push block 23 is fixedly installed, and the top end of the side of the push rod 22 is fixedly connected to the side of the push block 23. At both ends of the side of each limit clamping plate 2 close to the hollow tube 13, a transmission rod 24 is vertically fixedly installed, and the transmission rod 24 is slidably installed through the inner side of the side of the hollow tube 13. On the surface of each transmission rod 24 far from the limit clamping plate 2, a transmission block 25 is fixedly installed, and the transmission block 25 is located on both outer sides of the push block 23. A push spring 27 is movably sleeved in the middle of the inner part of the hollow tube 13, and both ends of the side of the push spring 27 are fixedly connected to the outer side of the push plate 21. A return spring 26 is movably sleeved on the outer surface of each transmission rod 24, and both outer sides of the return spring 26 are respectively movably attached to the transmission block 25 and the inner side wall of the hollow tube 13. Under the transmission action of the push block 23 and the transmission block 25, and under the structural pushing action of the return spring 26 and the push spring 27, after the medical staff only uses the thumb and index finger to push the push rods 22 located on both sides of the hollow tube 13, the limit clamping plate 2 is restored to its original position and disengages from the inner wall of the fixing groove 12. Furthermore, the limit clamping plate 2 loses the pushing and limiting force on the forceps handle 11. Then, the medical staff only needs to use the position of the palm's tiger's mouth to push both sides of the forceps handle 11 to quickly adjust the distance between the two groups of forceps handles 11. Furthermore, while facilitating the adjustment of the distance between the forceps handles 11, it is convenient to perform the pushing and fixing treatment on the two groups of forceps handles 11, avoiding any shaking that may affect the surgical quality.

[0028] Specifically, refer to Figures 1 to 4, sliding grooves 3 are formed in the middle of both ends of the outer side of the hollow tube 13, and the push rod 22 penetrates and is slidably inserted into the sliding groove 3. Under the guiding and sliding action of the sliding groove 3 on the push rod 22, after the medical staff pushes the push rod 22, the push rod 22 will not shift randomly to affect the rationality of transmission.

[0029] Furthermore, referring to Figures 1 to 4 , movable grooves 29 are formed in both ends of the outer side of the hollow tube 13, and the transmission rod 24 penetrates and is slidably installed in the movable groove 29. Under the guiding and sliding action of the movable groove 29 on the transmission rod 24, the stability of the transmission rod 24 during movement is ensured.

[0030] It should be noted that, referring to Figures 1 to 4 , an anti-slip friction pad 28 is fixedly inlaid on the side of each limiting clamping plate 2 away from the hollow tube 13, and the outer side of the anti-slip friction pad 28 is located inside the fixing groove 12. Through the structural action of the anti-slip friction pad 28, the stability of the limiting clamping plate 2 against the inner side of the forceps handle 11 can be improved.

[0031] It should be noted that, referring to Figures 1 to 4 , guide blocks 41 are fixedly installed on the surfaces of both ends of the outer side of each push plate 21. Guide grooves 4 are formed on both sides inside the hollow tube 13, and the guide blocks 41 are slidably inserted into the guide grooves 4. Under the guiding and sliding action of the guide grooves 4 on the guide blocks 41, when the push plate 21 is pushed, it can only move horizontally inside the hollow tube 13 without side shifting.

[0032] It is worth introducing that, referring to Figures 1 to 4 , a hand-push sleeve 5 is fixedly sleeved on the side of each push rod 22 away from the hollow tube 13, and the hand-push sleeve 5 is located outside the hollow tube 13. Through the structural action of the hand-push sleeve 5, it is convenient to push the push rod 22, and further convenient to adjust the rationality of the transmission of the position of the limiting clamping plate 2.

[0033] During operation, after medical staff hold the forceps handle 11 with their thumb and index finger, when the distance between the forceps handles 11 needs to be adjusted, the operator presses the push rod 22 inward by fitting the outer skin of the thumb and index finger to the hand-push sleeve 5. Under the guiding and sliding action of the guiding groove 4 on the guiding block 41, the push rod 22 can drive the push plate 21 and the push block 23 to move horizontally in opposite directions inside the hollow tube 13 synchronously. Then, when the push block 23 moves, the inclined surface of the push block 23 can be separated from the inclined surface of the transmission block 25, so that the push block 23 can lose the pushing force on the transmission block 25. Subsequently, under the reverse pushing action of the return spring 26, the transmission block 25 can be driven to move vertically synchronously. Under the transmission action of the transmission rod 24, the limit clamping plate 2 can be driven to move vertically outward from the inside of the fixed groove 12 inside the fixed groove 12, so that the limit clamping plate 2 can lose the pushing and limiting force on the forceps handle 11. Subsequently, the medical staff presses the two sides of the forceps handle 11 with the position of the tiger's mouth, so that the forceps handle 11 can be adjusted in distance to clamp and stop bleeding of blood vessels of different thicknesses. Then, the pushing force on the push rod 22 is released. Subsequently, under the reverse pushing action of the push spring 27, a corresponding pushing force can be provided to the push plate 21, so that the push plate 21 and the push block 23 are restored to their original positions. When the push block 23 moves under the push of the push spring 27, after its inclined surface and the inclined surface of the transmission block 25 are mutually attached, the transmission block 25 is pushed, so that the transmission block 25 can drive the limit clamping plate 2 to move outward relatively synchronously until the outside of the limit clamping plate 2 abuts and contacts the inside of the fixed groove 12 to perform the pushing and limiting process on the forceps handle 11. While facilitating the operation of the forceps handle 11, it can avoid any shaking of the forceps handle 11 from affecting the surgical use.
