Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic view of an embodiment of forceps according to the present application. The embodiment of the application provides a pair of surgical forceps, which comprises forceps handles 2, a first forceps leg 11 and a second forceps leg 12, and is characterized in that the surgical forceps further comprise a limiting part 4; the middle part of the limiting part is an elastic structure 43, the first end part 41 of the limiting part is connected with the middle part of the first forceps leg, and the second end part 42 of the limiting part is detachably connected with the middle part of the second forceps leg; the elastic structure has compression elasticity.

As a further optimized embodiment of the present invention, the surgical forceps further comprises an anti-slip sleeve 3; the anti-slip sleeves are two and respectively wrapped at the tip ends of the first forceps leg and the second forceps leg; further, the slip-preventing sleeve may be detachable from the tip of the first or second forceps leg.

Preferably, the material of the anti-slip sleeve is silica gel.

It should be noted that, the term "compressive elasticity" in this specification means that when a reaction force is generated in a compressed state, that is, when the limiting member is assembled between the first forceps leg and the second forceps leg and the forceps is held by an external force to move the first forceps leg and the second forceps leg towards each other to generate a grasping function, the limiting member is compressed due to the pressure acting on the two ends of the limiting member, and at this time, the elastic structure of the limiting member generates a reaction force to limit the grasping distance of the tip end of the forceps.

Fig. 2 is a schematic view of an embodiment of forceps according to the present application including a bolt. Preferably, the first end of the restriction member is a hole-like structure; the middle part of the first forceps leg comprises a first bolt 51 which is matched with the hole-shaped structure of the first end part, and the diameter of the top part of the first bolt is larger than that of the hole-shaped structure of the first end part; further preferably, the second end portion is a hole-like structure; the middle of the second forceps leg comprises a second bolt 52 which fits into the hole-like structure of the second end, the diameter of the top of the second bolt being smaller than the diameter of the hole-like structure of the second end.

Further preferably, the elastic structure is a compression spring, a V-shaped spring, a spring plate or a torsion spring, as shown in fig. 3 to 6.

FIG. 3 illustrates an embodiment of a restriction member of the present application, the resilient structure being a compression spring. As an embodiment, the first end portion and the second end portion of the restriction member are hole-shaped, and the middle portion is a compression spring. The figures show the form of the restricting member in the free state and the compressed state. The compression spring has a compression spring force, i.e., a reaction force is generated when the spring length is reduced in a compressed state.

As an embodiment, the first end part and the second end part of the limiting part are in a hole shape, and the middle part of the limiting part is a V-shaped spring. The figures show the form of the restricting member in the free state and the compressed state. The V-shaped spring has compression elasticity, namely, in a compression state, the V-shaped spring generates reaction force when the bending degree of the middle part is increased due to the compression of the two ends.

Fig. 5 is an embodiment of a restriction member of the present application, in which the elastic structure is a spring. As an embodiment, the first end part and the second end part of the limiting part are in a hole shape, and the middle part of the limiting part is an elastic sheet. The figures show the form of the restricting member in the free state and the compressed state. The elastic sheet has compression elasticity, namely, under a compression state, the elastic sheet generates reaction force when the bending degree of the middle part is increased due to the compression of the two ends.
