Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a wire guide forceps for orthopedic surgery. Background Technology
[0002] In orthopedic surgery, wire guide forceps play a crucial role. This tool utilizes two carefully designed arc-shaped guide tubes that, when mated together, effectively guide the wire along a specific path. This path is designed to ensure that the wire can pass through bone or other tissue structures with extremely high accuracy and stability. In this way, the wire can be precisely positioned to the exact location required for the surgery, thus providing a solid foundation for the success of the operation.
[0003] In clinical use, existing wire guide forceps require maintaining the two catheters in a closed state for an extended period when guiding the wire. This necessitates prolonged hand compression of the forceps and the two guiding tubes during surgery, causing continuous tension in the hand muscles and easily leading to hand fatigue. This affects the accuracy and efficiency of the surgery. Furthermore, the opening and closing angle of the forceps requires real-time control by the user, and cannot be temporarily fixed, increasing the burden on the medical staff's hands and hindering stable control of the forceps during surgery, thus affecting the surgical outcome. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing wire guide forceps have the disadvantage that the opening and closing angle cannot be fixed when they are used. To this end, we propose a wire guide forceps for orthopedic surgery.
[0005] To achieve the above objectives, this application adopts the following technical solution: a wire guide forceps for orthopedic surgery, comprising a support rod, two handles rotatably connected to the surface of the support rod, a guide tube fixedly connected to one end of each handle, a circular hole on the surface of the left handle, a perforated plate on one side of the right handle, a pressure plate slidably connected inside the right handle, an extension plate fixedly connected to the bottom of the pressure plate, a protruding rod fixedly connected to the top of the extension plate, and springs fixedly connected to both ends of the top of the extension plate, the tops of the springs being fixedly connected to the handles.
[0006] Preferably, a slot is provided on the top surface of the grip on the right side, and a T-shaped plate is fixedly connected to one end of the perforated plate, the T-shaped plate being inserted into the inner wall of the slot.
[0007] Preferably, a sleeve plate is fixedly connected to the bottom of the left-side grip, and the inner diameter of the sleeve plate is adapted to the surface size of the perforated plate.
[0008] Preferably, a sleeve is fixedly connected to the surface of the left-side grip, the inner diameter of the sleeve is tapered, and the inner wall is provided with file marks.
[0009] Preferably, a shearing blade is fixedly connected to the surface of the grip, and the two shearing blades are arranged in an offset manner.
[0010] Preferably, one end of the conduit is fixedly connected to a connector, and the surface of the connector is provided with a groove.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] In this invention, by using a spring in conjunction with a protruding rod, medical personnel can press the pressure plate during clinical operation to control the protruding rod to insert into the hole of the perforated plate, thus fixing the opening and closing angle between the two handles. This allows medical personnel to restrict the docking position of the two catheters without having to hold the two handles for a long time, thereby reducing hand fatigue. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0019] Reference Figures 1-4As shown, this utility model provides a technical solution: a wire guide forceps for orthopedic surgery, including a support rod 1, two handles 2 rotatably connected to the surface of the support rod 1, a guide tube 3 fixedly connected to one end of each handle 2, a round hole 4 on the surface of the left handle 2, a perforated plate 5 on one side of the right handle 2, a pressure plate 6 slidably connected inside the right handle 2, an extension plate 7 fixedly connected to the bottom of the pressure plate 6, a protruding rod 8 fixedly connected to the top of the extension plate 7, and springs 9 fixedly connected to both ends of the top of the extension plate 7. The tops of the springs 9 are fixedly connected to the handles 2. When the user holds the two handles 2 and guides the wire using the guide tube 3, the user presses the pressure plate 6 with their hand to push the extension plate 7 downward. The movement causes the protruding rod 8 to be pulled out from the holes in the perforated plate 5 and the round hole 4, and the extension plate 7 to move downwards to pull the spring 9 to store force. Then, the user rotates the two handles 2 and the catheter 3 to the required angle, so that the handles 2 are closed or open. Then the user releases the pressure plate 6, so that the spring 9 releases the force generated, rebounds and pulls the extension plate 7 to drive the protruding rod 8 to be inserted into the holes in the perforated plate 5 and the round hole 4, thereby fixing the use angle of the two handles 2. In actual use, the user does not need to squeeze the two handles 2 for a long time to close them, so that the two catheters 3 can be tightly connected, thereby reducing the fatigue of medical staff's hands and making it easier for the user to adjust and fix the distance between the two catheters 3.
[0020] Reference Figures 1-3 As shown in this embodiment: a slot 10 is provided on the top surface of the right grip 2, and a T-shaped plate 11 is fixedly connected to one end of the perforated plate 5. The T-shaped plate 11 is inserted into the inner wall of the slot 10. Through the insertion of the T-shaped plate 11 into the slot 10, the perforated plate 5 can be removed from one side of the grip 2. Through the staggered design of the two grips 2, when the perforated plate 5 is installed on one side of the grip 2, the bottom of the other grip 2 can move along the surface of the perforated plate 5. When the perforated plate 5 is open and closed at an arc angle, one grip 2 can restrict the T-shaped plate 11 inside the slot 10. When the opening and closing angle of the two grips 2 is greater than the arc of the perforated plate 5, the two grips 2 no longer restrict the position of the perforated plate 5, so that the T-shaped plate 11 can be pulled out from inside the slot 10. Through the ingenious design between the structures, it is convenient for users to install or remove the perforated plate 5.
[0021] Reference Figure 2 and Figure 3As shown in this embodiment: a sleeve plate 12 is fixedly connected to the bottom of the left grip 2. The inner diameter of the sleeve plate 12 is adapted to the surface size of the perforated plate 5. When the grip 2 rotates, the sleeve plate 12 slides on the surface of the perforated plate 5, thereby restricting the position between the perforated plate 5 and the grip 2, so that the perforated plate 5 is always tightly connected to the top grip 2. At the same time, one end of the perforated plate 5 is also constrained by the position of the T-shaped plate 11 and the slot 10, so that the perforated plate 5 is tightly connected to the grip 2. When the grip 2 rotates, the perforated plate 5 is not prone to tilting, which would affect the docking accuracy of the protruding rod 8 with the perforated plate 5.
[0022] Reference Figures 1-3 As shown in this embodiment: a sleeve 13 is fixedly connected to the surface of the left handle 2. The inner diameter of the sleeve 13 is tapered, and the inner wall is provided with file marks. When medical personnel cut the excessively long steel wire, they insert the cut end into the hole of the sleeve 13. Through the design of the tapered structure inside the sleeve 13 gradually narrowing from the opening, the inner wall of the sleeve 13 can accommodate steel wires of different widths. When the steel wire is inserted into the sleeve 13 and is in close contact with the inner wall of the sleeve 13, the file marks on the inner wall of the sleeve 13 allow the user to rotate and rub the cut end of the steel wire against the file marks inside the sleeve 13, thereby polishing the burrs after the steel wire is cut, and avoiding the steel wire from scratching the patient's internal tissues during subsequent use.
[0023] Reference Figure 3 As shown in this embodiment: a shearing blade 14 is fixedly connected to the surface of the handle 2. The two shearing blades 14 are arranged in an offset manner. By setting the shearing blades 14, when the two handles 2 are rotated and closed, the user can place the steel wire between the two shearing blades 14. By pressing the handle 2, the two shearing blades 14 are closed, thereby achieving the cutting of the steel wire. At the same time, the offset arrangement of the two shearing blades 14 makes the steel wire more stably fixed during the cutting process, avoiding the steel wire from shifting or slipping during cutting, improving the accuracy and safety of cutting, reducing the operation time of medical personnel during the operation, and improving the efficiency of the operation.
[0024] Reference Figure 4As shown in this embodiment: one end of the catheter 3 is fixedly connected to a connector 15. The surface of the connector 15 has a groove 16. By enlarging the docking hole of the catheter 3 through the inner wall of the two connectors 15, when the two connectors 15 are spliced, the steel wire can be smoothly guided through the rounded inner wall of the connector 15 to the other connector 15 and then pass into the catheter 3. This avoids the steel wire getting stuck or scratched due to the docking hole being too narrow, thus ensuring the smoothness and safety of the steel wire during the guidance process. The groove 16 allows the user to control the two catheters 3 to close tightly by holding the handle 2, so that the steel wire is placed inside the two grooves 16, and the connector 15 clamps the surface of the steel wire. This allows the device to clamp the steel wire, so that medical personnel can flexibly manipulate and pull the steel wire during the operation.
[0025] Working principle: When the user holds the two handles 2 and guides the steel wire with the guide tube 3, the user presses the pressure plate 6 to push the extension plate 7 downward, causing the protruding rod 8 to be pulled out from the hole in the perforated plate 5 and the round hole 4. This causes the extension plate 7 to move downward and pull the spring 9 to store force. Then, the user rotates the two handles 2 and the guide tube 3 to the required angle, so that the handles 2 are closed or open. After that, the user releases the pressure plate 6, causing the spring 9 to release the force, rebound and pull the extension plate 7 to drive the protruding rod 8 into the hole in the perforated plate 5 and the round hole 4, thereby fixing the usage angle of the two handles 2.
[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
