[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Embodiment 1

[0024] The utility model provides a surgical forceps, see Figure 1 , including first handle 1 and second handle 2, the first handle one end sets up first finger ring 1-1, the second handle one end is provided with second finger ring 2-1, the other end of first handle and the other end of second handle articulate, the first handle is away from the one end of first finger ring and extends to the outside (i.e. the side away from first finger ring) and forms first forceps head 1-2, the second handle is away from the one end of second finger ring and extends to the outside (i.e. the side away from second finger ring) and forms second forceps head 2-2, the first handle is provided with the first extension piece 1-3 extending to the second handle direction, and the first extension piece is located at the side of second handle opposite first handle;The second handle is provided with the second extension piece 2-3 extending to the first handle direction, and the second extension piece is located at the side of first handle opposite second handle;The first extension piece is provided with the first blocking piece for limiting the movement of second handle to the direction away from first handle;The second extension piece is provided with the second blocking piece for limiting the movement of first handle to the direction away from second handle, and blocking piece can use prior art structure, in order to facilitate adjustment, applicant has made the following design: the first extension piece is provided with first strip hole 1-4 and first bolt 4, the first bolt is provided with first nut, and the first bolt penetrates the first strip hole;

[0025] The second extension piece is provided with second strip hole 2-4 and second bolt 5, the second bolt is provided with second nut, and the first bolt penetrates the second strip hole;Wherein, the first handle and second handle can be articulated through pin shaft 3;The first extension piece and second extension piece are arc-shaped and coaxially arranged with the pin shaft.

[0026] The surgical forceps of the embodiment has the following advantages:

[0027] 1. By tightening the first nut, the first bolt can be fixed at a position on the first extension piece corresponding to the first slot; by tightening the second nut, the second bolt can be fixed at a position on the second extension piece corresponding to the second slot. In this way, the first bolt restricts the movement of the second clamp handle away from the first clamp handle, and the second bolt restricts the movement of the first clamp handle away from the second clamp handle. This gives the surgical forceps a limiting function for the opening and closing angle, preventing the surgical forceps from opening and closing too wide and injuring the patient. The first and second slots allow the first and second bolts to move within a certain range when the corresponding nuts are loosened, so as to adjust the size of the limiting angle and adapt to stronger forces.

[0028] 2. Since the first extension piece is located on the side of the second clamp handle directly opposite the first clamp handle, and the second extension piece is located on the side of the first clamp handle directly opposite the second clamp handle, the first clamp handle is in contact with the second extension piece, and the second clamp handle is in contact with the first extension piece. Therefore, the first and second clamp handles can maintain parallel movement during the opening and closing process, preventing the first and second clamp handles from tilting relative to each other and rubbing against the pin during the movement, which would cause the first and second clamp handles to shake when opening and closing, affecting the use effect.

[0029] For easy and precise adjustment, scale lines can be provided on both the first and second extension plates.

[0030] Example 2

[0031] See Figures 2-6 Example 2 is a further improvement on Example 1, differing from Example 1 in that: a triangular cutting portion 1-5 and a trapezoidal blocking block 6 are provided at the end of the first pliers head away from the first finger ring; the trapezoidal blocking block and the triangular cutting portion are combined to form a square structure; the trapezoidal blocking block is detachably connected to the first pliers head; as one implementation method, see 3- Figure 5 The trapezoidal sealing block may be provided with a dovetail tenon 6-1, and the first pliers head is provided with a dovetail groove that mates with the dovetail tenon. The dovetail tenon is inserted into the dovetail groove and fixed by friction. This structure allows the trapezoidal block to be pulled out and removed, so that the triangular cutting part forms a blade. This, combined with the second pliers head, enables simple cutting operations. As one embodiment, see [reference needed]. Figure 6 A screw 7 is provided on the triangular cut section, and a third nut 8 is provided on the screw. The screw passes through the trapezoidal sealing block. When it is necessary to remove the trapezoidal block, simply remove the nut and remove the trapezoidal sealing block from the screw.

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. In the case of no conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0034] The above-mentioned embodiments only express the implementation of the utility model, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
