Detailed Description of the Preferred Embodiment

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0023] An embodiment of the present application provides a separating forceps for uterine fibroids surgery. The separating forceps for uterine fibroids surgery can realize the replacement of the required forceps head according to actual operation needs through the disassembly and assembly component, reduce the preoperative preparation time before surgery, and a set of forceps arms can use multiple forceps heads, which reduces the cost. When wear and other conditions occur in a single part, it can be replaced separately.

[0024] The following is a detailed description of the separating forceps for uterine fibroids surgery. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0025] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Please refer to Figures 1-7 In the figure, a separating forceps for uterine fibroids surgery provided in this embodiment includes: two forceps arms 1, which are rotatably connected by a rotating shaft between the two forceps arms 1. One end of each of the two forceps arms 1 is provided with a forceps head 11, and the other end of each of the two forceps arms 1 is provided with a forceps handle 12. One end of each of the two forceps handles 12 is fixedly connected with a finger ring 13, a disassembly and assembly component, which is arranged between the two forceps heads 11 and the two forceps arms 1 for quickly replacing the required forceps head 11. The disassembly and assembly component includes: a plug-in slot 2, a plug-in head 21, a movable slot 22, a pull rod 23, a clamping block 24 and a clamping slot 25, and a bending component, which is arranged between the two forceps handles 12 and the two forceps arms 1 for bending the forceps handle 12. The bending component includes: a rotating block 3, a connecting cylinder 31, a moving rod 32, a limiting plate 33 and a fixing rod 34.

[0026] When in use, the fingers pass through the finger rings 13 to control the opening and closing of the forceps handles 12. The forceps handles 12 drive the forceps arms 1 to move, so that the forceps heads 11 complete the operations of clamping and loosening. Different types of forceps heads 11 can be replaced through the disassembly and assembly component, and the working angle of the forceps handles 12 can be adjusted through the bending component, which is beneficial to the operation of the surgery.

[0027] In some embodiments, plug-in slots 2 are respectively opened at one end of the two forceps arms 1 close to the forceps heads 11. One end of each of the two forceps heads 11 is fixedly connected with a plug-in head 21. Movable slots 22 are respectively opened at positions on the opposite sides of the two forceps arms 1 close to the plug-in slots 2. Pull rods 23 are slidably connected inside the movable slots 22. One end of each of the pull rods 23 facing the plug-in slot 2 is fixedly connected with a clamping block 24. Two symmetrically arranged clamping slots 25 are respectively opened on the plug-in heads 21. Receiving slots 26 matching the clamping blocks 24 are respectively opened on the inner walls of the opposite sides of the two plug-in slots 2. A spring a 27 is sleeved outside the pull rod 23. A push plate 28 matching the spring a 27 is fixedly connected to the outside of the pull rod 23. One end of the spring a 27 is in contact with the movable slot 22, and the other end of the spring a 27 is in contact with the push plate 28. Grooves 29 are opened at positions on the two forceps arms 1 opposite to the movable slots 22. A rubber sealing cover 210 is rotatably connected to the grooves 29. One end of the pull rod 23 extends into the groove 29 and is fixedly connected with a pull ring 211.

[0028] During use, select the required model of the matching jaw 11. Open the rubber seal cover 210 and use a tool to hook the pull ring 211 to pull the pull rod 23, so that the pull rod 23 drives the clamping block 24 to retract into the storage groove 26. When the pull rod 23 moves, it drives the push plate 28 to squeeze the spring a27, causing the spring a27 to contract and store energy. Pull both clamping blocks 24 into the storage groove 26. Then insert the plug connector 21 at one end of the jaw 11 into the plug-in groove 2 until it reaches the bottom. Then release the pull ring 211, and the spring a27 releases its elasticity. The elastic force of the spring a27 acts on the push plate 28, pushing the pull rod 23 to eject towards one end of the storage groove 26, so that the clamping block 24 moves from the storage groove 26 to the card slot 25 on the plug connector 21, thereby fixing the jaw 11. Then cover the rubber seal cover 210 to seal the groove 29, so that jaws 11 of different models can be replaced.

[0029] In some embodiments, rotation blocks 3 are fixedly connected to one ends of the two jaw arms 1 close to the two jaw handles 12. Connecting grooves are respectively formed at one ends of the two jaw handles 12 close to the jaw arms 1. Through grooves communicating with the connecting grooves are respectively formed on the rotation blocks 3 and the jaw handles 12. The rotation blocks 3 are inserted into the connecting grooves. A connecting cylinder 31 is provided between the two through grooves. The rotation blocks 3 and the connecting cylinder 31 are rotatably connected. A moving rod 32 is provided inside the connecting cylinder 31. Limiting plates 33 are respectively fixedly connected to opposite ends of the two moving rods 32. A plurality of fixing rods 34 arranged in an annular array are fixedly connected to one side of the limiting plate 33 close to the jaw handle 12. Through holes for several fixing rods 34 to pass through are respectively formed in the two jaw handles 12. Fixing grooves 35 matching with several fixing rods 34 are respectively formed on the two rotation blocks 3. Pressing plates 36 are respectively fixedly connected to one ends of the two moving rods 32 far from the center. Springs b37 are respectively sleeved on the outer parts of the two moving rods 32 close to the pressing plates 36. One end of the spring b37 is in contact with the pressing plate 36, and the other end of the spring b37 is in contact with the jaw handle 12.

[0030] During the reoperation process, when it is necessary to adjust the inclination angle of the forceps handle 12, press the pressing plate 36 so that the pressing plate 36 pushes the moving rod 32 to move inside the connecting cylinder 31. The connecting cylinder 31 is used to connect the rotating block 3 and the forceps handle 12. When the pressing plate 36 is pressed, it will squeeze the spring b37, and the spring b37 will be compressed and store energy. At this time, the moving rod 32 pushes the limiting plate 33 to move, so that the fixing rod 34 on the limiting plate 33 exits from the fixing groove 35 and moves to the through hole for temporary storage, thereby releasing the fixation of the rotating block 3. Subsequently, rotate the forceps handle 12, and the forceps handle 12 rotates around the connecting cylinder 31, thereby adjusting the inclination angle of the forceps handle 12. After adjusting the angle, ensure that the fixing groove 35 is aligned with the through hole. Then release the pressing plate 36, and the spring b37 releases its elasticity. The spring b37 pushes the pressing plate 36 to move in the reverse direction, so that the moving rod 32 drives the fixing rod 34 on the limiting plate 33 to move into the fixing groove 35, thereby fixing the rotating block 3 and the forceps handle 12, and adjusting the position of the forceps handle 12 in this way, which is more conducive to observation and surgical operation.
