Description

Technical Field

[0001] This utility model relates to the field of surgical forceps technology, and in particular to surgical forceps with replaceable forceps heads. Background Technology

[0002] Surgical forceps are essential medical instruments in surgical procedures. During surgery, they primarily play a crucial role in clamping and securing tissues or instruments. For example, in delicate surgical procedures, surgical forceps can accurately clamp blood vessels, nerves, and other tissues, preventing movement and providing a stable environment for the surgeon to proceed with further operations. Simultaneously, surgical forceps also serve to hold small surgical instruments or instruments in place, ensuring the smooth progress of the surgery.

[0003] Current surgical forceps have several significant drawbacks. One major drawback is that most forceps heads are bolted together. This method presents numerous inconveniences in practical use. First, bolted connections typically require specific tools for disassembly, and finding and using these tools during surgery wastes valuable time. Second, disassembling bolted connections is relatively cumbersome, requiring multiple steps, which undoubtedly impacts surgical efficiency in time-sensitive environments. This inconvenience is particularly pronounced when changing different types of forceps heads. The cumbersome and time-consuming process can prolong surgical time and increase patient risks. To address this issue, a surgical forceps with replaceable heads is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surgical forceps with replaceable forceps heads.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A surgical forceps with replaceable forceps heads includes a first handle and a second handle. Both the first and second handles have mounting grooves, in which a first forceps head and a second forceps head are respectively mounted. Both the first and second handles have openings and internal rotating cavities. A screw extending into the opening is rotatably mounted within each rotating cavity. The second handle has a T-shaped fixing rod, on which a movable plate is slidably mounted via an elastic mechanism. The movable plate is connected to the screw via a rotating mechanism. A positioning plate threaded onto the screw is located within the rotating cavity via a limiting rod. Both the first and second forceps heads have positioning grooves corresponding to the positioning plates.

[0007] Preferably, the elastic mechanism includes a spring sleeved on the outside of the T-shaped fixing rod, with both ends of the spring elastically connected to the outer wall of the second clamp handle and the outer wall of the head of the T-shaped fixing rod, respectively.

[0008] Preferably, the rotating mechanism includes a rotating shaft that is rotatably mounted on a movable plate, a drive gear is provided on the rotating shaft, and a transmission gear that meshes with the drive gear is provided on the screw.

[0009] Preferably, the vertical cross-sectional view of the rotating cavity is L-shaped, and the vertical cross-sectional view of the positioning plate is also L-shaped.

[0010] Preferably, the vertical cross-section of the T-shaped fixing rod is rectangular, and the movable opening on the movable plate corresponding to the T-shaped fixing rod is also rectangular.

[0011] Preferably, both the driving gear and the transmission gear are bevel gears, and the meshing relationship between the driving gear and the transmission gear is perpendicular meshing.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up structures such as mounting slots, screws, positioning plates, and positioning grooves, the interchangeability of the forceps head is achieved, making it convenient to select the appropriate forceps head according to different surgical needs.

[0014] 2. The combination of elastic, rotating, and limiting mechanisms makes the replacement of the forceps head simpler and improves surgical efficiency.

[0015] 3. The drive gear and transmission gear adopt a bevel gear perpendicular meshing method, which ensures stable and reliable transmission.

[0016] 4. The rotating block on the movable plate facilitates the rotation of the rotating shaft, and the curved outer wall is provided with anti-slip texture, which increases the convenience of operation.

[0017] 5. The special shape design of the T-shaped fixing rod and the movable plate prevents the movable plate from rotating relative to the T-shaped fixing rod, thus playing a limiting role. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-3 A surgical forceps with replaceable heads includes a first handle 1 and a second handle 2. Both the first handle 1 and the second handle 2 are provided with mounting grooves 3. A first head 4 and a second head 5 are respectively installed in the two mounting grooves 3. Both the first handle 1 and the second handle 2 are provided with openings 6. Both the first handle 1 and the second handle 2 are provided with rotating cavities 13. A screw 14 extending into the opening 6 is rotatably installed in both rotating cavities 13. The second handle 2 is provided with a T-shaped fixing rod 7. A movable plate 8 is slidably sleeved on the T-shaped fixing rod 7 through an elastic mechanism. The movable plate 8 is connected to the screw 14 through a rotating mechanism. A positioning plate 16 threaded onto the screw 14 is provided in the rotating cavity 13 through a limiting rod 17. Both the first head 4 and the second head 5 are provided with positioning grooves 18 corresponding to the positioning plate 16.

[0024] The elastic mechanism includes a spring 9 sleeved on the outside of the T-shaped fixing rod 7. The two ends of the spring 9 are elastically connected to the outer wall of the second clamp 2 and the outer wall of the head of the T-shaped fixing rod 7, respectively. The elastic potential energy provided by the spring 9 ensures that, without the intervention of external force, the movable plate 8 and the drive gear 12 and other components are kept away from the transmission gear 15, so that the drive gear 12 does not mesh with the transmission gear 15.

[0025] The rotating mechanism includes a rotating shaft 10 that is rotatably mounted on a movable plate 8. A drive gear 12 is mounted on the rotating shaft 10, and a transmission gear 15 that meshes with the drive gear 12 is mounted on the screw 14. Both the drive gear 12 and the transmission gear 15 are bevel gears, and their meshing relationship is perpendicular. When the drive gear 12 and the transmission gear 15 mesh, the rotating shaft 10 rotates, ultimately driving the screw 14 to rotate.

[0026] In this design, the movable plate 8 is also provided with a rotating block 11 connected to the rotating shaft 10. The rotating block 11 facilitates the rotation of the rotating shaft 10, and the outer arc-shaped wall of the rotating block 11 is provided with anti-slip texture.

[0027] The vertical cross-sectional view of the rotating cavity 13 is L-shaped, and the vertical cross-sectional view of the positioning plate 16 is also L-shaped. For specific shapes, please refer to the appendix. Figure 3 As shown.

[0028] The vertical cross-section of the T-shaped fixing rod 7 is rectangular, and the movable opening on the movable plate 8 corresponding to the T-shaped fixing rod 7 is also rectangular. This shape prevents the movable plate 8 from rotating relative to the T-shaped fixing rod 7, thus serving a limiting function.

[0029] In use, this invention begins with the spring 9 in its natural state without external force, keeping the movable plate 8 and the drive gear 12 away from the transmission gear 15. At this time, the drive gear 12 does not mesh with the transmission gear 15. When it is necessary to replace the first jaw 4 and the second jaw 5, the movable plate 8 is pushed against the spring force of the spring 9 and moved closer to the transmission gear 15, causing the drive gear 12 to mesh with the transmission gear 15. Rotating the rotating block 11 on the movable plate 8 then rotates the rotating shaft 10, which in turn rotates the drive gear 12, thereby rotating the transmission gear 15. The transmission gear 15 drives the screw 14 to rotate within the rotating cavity 13. Since the positioning plate 16 is positioned within the rotating cavity 13 via the limiting rod 17 and threaded onto the screw 14, the rotation of the screw 14 causes the positioning plate 16 to move within the rotating cavity 13. When the positioning plate 16 is removed from the positioning groove 18 on the first pliers head 4 and the second pliers head 5, the first pliers head 4 and the second pliers head 5 can be removed from the mounting groove 3 on the first pliers handle 1 and the second pliers handle 2 for replacement.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
