Description

Technical Field

[0001] The invention relates to the technical field of gynecological surgical instruments, and in particular to a uterine fibroid removal forceps. Background Art

[0002] Uterine fibroids are one of the most common benign tumors in the female reproductive organs and one of the most common types of tumors in the whole body. They are usually called fibroids or uterine fibroids. They may have various effects on women's health, especially in the case of larger fibroids or special locations. They may cause discomfort symptoms such as irregular menstruation, abdominal pain, pressure, and even infertility. In surgical treatment, uterine fibroid removal forceps are one of the commonly used surgical tools. With this professional surgical instrument, doctors can clamp and remove fibroids more accurately during surgery, thereby improving the safety and efficiency of the operation.

[0003] However, during the operation of conventional extraction forceps, the operator is usually required to apply a certain continuous force to clamp and fix the uterine fibroids for removal. At the same time, the clamping position of the extraction forceps may need to be adjusted multiple times during the removal process, which requires the operator to frequently open and close the forceps, increasing the complexity of the operation. At the same time, during the process of fibroid removal, unstable clamping may cause the fibroids to accidentally slip, thereby affecting the efficiency of the operation and the smoothness of the operation.

[0004] Therefore, we make improvements on this and propose a uterine fibroid removal forceps. Summary of the invention

[0005] The purpose of the present invention is to provide a uterine fibroid removal forceps, which solves the problem in the prior art that during the operation, the operator is usually required to apply a certain continuous force to clamp and fix the uterine fibroid for removal operation. At the same time, during the clamping process, the clamping position of the fibroid may need to be adjusted multiple times, which requires the operator to frequently perform opening and closing operations, increasing the complexity of the operation. At the same time, during the process of fibroid removal, unstable clamping may cause the fibroid to accidentally slip, thereby affecting the surgical efficiency and operation fluency.

[0006] The specific application is as follows: It comprises a fixing seat, in which two handles are hingedly connected by a pin shaft, one side of the fixing seat is fixedly connected with an empty tube, one side of the empty tube is fixedly connected with a fixing clamp, the two handles are installed with a same clamping device for fixing the fibroids, the two handles are fixedly connected with a same limiting device for locking the fibroids after fixation, both handles are provided with long grooves, and one of the long grooves is installed with a pressing device for releasing the limit of the fibroids.

[0007] As a preferred technical solution of the present application, the clamping device includes two fixed shafts, the fixed shafts are fixedly connected in the long groove, a rotating rod is rotatably connected outside the fixed shaft, the two rotating rods are hinged with the same ring through a pin, a pull rod is connected through the ring, the pull rod is slidably connected in the fixed seat, the pull rod is slidably connected in the empty tube, one end of the pull rod is movably connected to a movable clamp, and the movable clamp is hinged in the empty tube through a pin.

[0008] As a preferred technical solution of the present application, the movable clamp is fixedly connected with a plurality of cutting teeth for facilitating the removal and fixation of the myoma.

[0009] As a preferred technical solution of the present application, the limiting device includes a locking rod, a tooth plate and a shell. The locking rod is hinged in the upper handle through a pin shaft, a hook is fixedly connected under the locking rod, the shell is fixedly connected in the upper handle, and a long rod is fixedly connected in the shell.

[0010] As a preferred technical solution of the present application, the toothed plate is fixedly connected in the lower handle, and the long rod and the hook are provided with a same return spring.

[0011] As a preferred technical solution of the present application, a protrusion is provided at the lower part of the locking rod to facilitate locking in the tooth plate.

[0012] As a preferred technical solution of the present application, the pressing device includes a swinging plate and a rectangular slot, the swinging plate is hinged in a long slot through a pin shaft, a pressure plate is fixedly connected to the swinging plate, a rope is fixedly connected under the swinging plate, the rectangular slot is opened in the locking rod, a limiting rod is fixedly connected in the rectangular slot, and the rope is movably connected outside the limiting rod.

[0013] As a preferred technical solution of the present application, the upper surface of the pressing plate is provided with anti-skid patterns for preventing skidding.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. Through the setting of the clamping device, when clamping the uterine fibroid, the operator presses the two handles to apply a squeezing force. At this time, the two handles transmit force through the rotating rod, and the rotating rod rotates around the pin in the long groove, driving the ring to move in the long groove. The movement of the ring directly drives the pull rod connected thereto to move forward synchronously, thereby promoting the sliding connection between the pull rod and the fixed seat and the empty tube. One end of the pull rod is connected to the mobile clamp, which is hinged in the empty tube through the pin. At the same time, the mobile clamp also moves synchronously, and finally the cutting teeth are aligned and clamped. In this process, the cutting teeth firmly clamp the fibroid by cooperating with the tooth plate to ensure that it will not fall off during the operation. At the same time, the engagement of the tooth plate with the locking rod further enhances the stability of the clamping. This design solves the problem that the conventional removal forceps in the prior art require the operator to continuously apply force to ensure the fixation of the fibroid, thereby avoiding the risk of accidental slippage of the fibroid during the removal process. While ensuring stable clamping, the operator only needs to pull the handle to smoothly remove the fibroid from the uterus, simplifying the operation process and improving the safety and efficiency of the operation.

[0015] 2. Through the setting of the limit device in conjunction with the pressing device, when the clamping position needs to be continuously adjusted, it is only necessary to press the pressure plate, and then the pressure plate drives the swing plate to rotate in the long groove through the pin shaft, and then the swing plate applies tension to the rope, and the tension drives the locking rod to move. When the locking rod is disengaged from the tooth plate, the clamping position of the fibroid can be readjusted at this time. When the pressure plate is released, the return spring applies tension to the hook, and the tension drives the hook and the locking rod to move synchronously. At this time, the locking rod rotates and resets in a handle through the pin shaft. After the fibroid is taken out, it is only necessary to repeat the above steps to press the pressure plate. This solves the problem that the clamping position of the fibroid may need to be adjusted multiple times during the clamping process in the prior art, which requires the operator to frequently perform opening and closing operations, increasing the complexity of the operation.

[0022] See also Figures 1 to 6The present invention provides a technical solution: a uterine fibroid removal forceps, comprising a fixing seat 1, two handles 2 are hingedly connected in the fixing seat 1 through a pin shaft, a hollow tube 3 is fixedly connected to one side of the fixing seat 1, a fixing clamp 4 is fixedly connected to one side of the hollow tube 3, a clamping device 5 for fixing the fibroid is installed in the two handles 2, a limiting device 6 for locking the fibroid after fixation is fixedly connected in the two handles 2, long grooves 7 are opened in the two handles 2, and a pressing device 8 for releasing the limit of the fibroid is installed in one of the long grooves 7.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the clamping device 5 includes two fixed shafts 51, the fixed shaft 51 is fixedly connected in the long slot 7, the fixed shaft 51 is rotatably connected with a rotating rod 52 outside, the two rotating rods 52 are hinged with the same sleeve 53 through a pin shaft, and a pull rod 54 is connected through the sleeve 53, the pull rod 54 is slidably connected in the fixed seat 1, the pull rod 54 is slidably connected in the empty tube 3, one end of the pull rod 54 is movably connected with a movable clamp 55, the movable clamp 55 is hinged in the empty tube 3 through a pin shaft, and the movable clamp 55 A plurality of cutting teeth 56 are fixedly connected internally for facilitating the removal and fixation of the myoma. The limiting device 6 comprises a locking rod 61, a tooth plate 62 and a shell 64. The locking rod 61 is hinged in the upper handle 2 through a pin shaft. A hook 63 is fixedly connected below the locking rod 61. The shell 64 is fixedly connected in the upper handle 2. A long rod 65 is fixedly connected in the shell 64. The tooth plate 62 is fixedly connected in the lower handle 2. The long rod 65 and the hook 63 are hung with the same pull-back spring 66. A protrusion is provided at the lower part of the locking rod 61 for easy clamping in the tooth plate 62. By setting the return spring 66, the use of the return spring 66 enables the hook 63 and the locking rod 61 to automatically reset after the pressing device 8 is released, ensuring that they can accurately return to the locked state after each adjustment. This automatic reset design reduces the labor intensity of the operator and improves the continuity and reliability of the operation; by setting the combination of the movable clamp 55 and the cutting tooth 56, the stable clamping of the myoma is ensured during the entire removal process, avoiding accidental slippage and increasing the success rate of removal; through the cooperation between the locking rod 61 and the tooth plate 62, when it is necessary to release the limit and adjust the clamping position, the swing plate 81 of the pressing device 8 drives the pressure plate 82 to apply pressure, pushing the locking rod 61 out of the tooth plate 62. Through this mechanism, the operator can easily adjust the clamping position without repeatedly operating the handle 2, thereby reducing the complexity of the operation and improving the efficiency of the operation.

[0024] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the pressing device 8 includes a swing plate 81 and a rectangular slot 84, the swing plate 81 is hinged in a long slot 7 through a pin, a pressing plate 82 is fixedly connected to the swing plate 81, a rope 83 is fixedly connected to the swing plate 81, the rectangular slot 84 is opened in the locking rod 61, a limiting rod 85 is fixedly connected in the rectangular slot 84, the rope 83 is movably connected to the outside of the limiting rod 85, and the upper surface of the pressing plate 82 is provided with anti-skid patterns for anti-skid. By providing the rope 83 and the swing plate 81, the connection of the rope 83 enables the swing plate 81 to apply a pulling force to the limiting rod 85 when driving the pressing plate 82, thereby pushing the limiting rod 85 to move. When the rope 83 acts on the limit rod 85, the engagement between the locking rod 61 and the tooth plate 62 can be released, allowing the operator to adjust the clamping position. The advantage of this structure is that, through the movable connection of the rope 83, the operator can control the limit release and reset operations in a relatively easy manner without frequent adjustments or excessive force; by setting the pressure plate 82, the anti-slip grooves provided on the pressure plate 82 increase the contact friction between the pressure plate 82 and the operator's hand, which helps to ensure that the operator can obtain a better sense of control during operation and avoid operational errors caused by hand slippage. The design of the anti-slip grooves improves the accuracy of the operation, especially when a certain pressure needs to be applied to adjust the clamping state, it can ensure stability; by setting the swing plate 81, the swing plate 81 is hinged in the long slot 7 through a pin shaft, so that the swing plate 81 can swing in the long slot 7. This design provides a simple and effective mechanical transmission method. When the operator applies pressure, the swing plate 81 rotates along the long slot 7.

[0025] Specifically, when the present uterine fibroid removal forceps are in use: when clamping the fibroid, the operator presses down the two handles 2, and by applying a squeezing force, the two handles 2 act together on the rotating rod 52, generating a rotational torque, and the rotating rod 52 rotates in the long groove 7 through the pin shaft, and this rotation drives the ring 53 to translate along the trajectory, and the movement of the ring 53 drives the pull rod 54 to move forward synchronously, and the pull rod 54 is connected to the sliding in the empty tube 3 and the fixed seat 1, driving the mobile clamp 55 to rotate along the pin shaft in the empty tube 3, with the movement of the mobile clamp 55, the cutting teeth 56 in the clamp tightly clamp the fibroid, thereby fixing the fibroid, and at the same time, the tooth plate 62 and the locking rod 61 are engaged with each other, and the locking rod 61 maintains a stable clamping state to prevent the fibroid from falling off during operation, and then the operator can pull the handle 2 to make the entire device The fibroid is successfully removed. If the clamping position needs to be adjusted, the operator only needs to press the pressure plate 82, and the pressure plate 82 drives the swing plate 81 to rotate in the long groove 7 through the pin shaft. The swing plate 81 drives the rope 83 to apply tension, and then pushes the locking rod 61 to move along its track. When the locking rod 61 is separated from the tooth plate 62, the clamping position of the fibroid can be freely adjusted to ensure the accuracy and stability of the clamping. After releasing the pressure plate 82, the return spring 66 applies tension to make the hook 63 and the locking rod 61 move synchronously, driving the locking rod 61 to reset through the pin shaft. At this time, the limit device 6 returns to the initial position to ensure that the clamping state is restored. The whole process can be repeated continuously. The clamping position and stability can be accurately adjusted by pressing and releasing the pressure plate 82, thereby ensuring the smoothness and safety of the surgical operation.
