Abstract

The utility model relates to surgical forceps, which is formed by that a plate which has two acuminate heads is bent, wherein, the bended part of the plate has elasticity. Surfaces of the inner sides of two forceps clamps are provided with guide devices which can increase the toughness of the two forceps clamps and help the forceps clamps to position accurately. The utility model has the advantages that structure is simple, toughness is large, and things can be clamped accurately and powerfully.

Description

A kind of tweezers

This utility model relates to a kind of tweezers.

Tweezers almost are indispensable instruments at laboratory, infirmary particularly for common tool in life, the scientific research.Pattern is wide, specification is many.A kind of medical tweezers are arranged at present, are to be that pointed plates bending forms by two ends, as shown in Figure 1.Its knee has elasticity, so available hands is taken the photograph it, with the clamping thing, but since up and down two plates be in free state, user firmly has difference partially slightly, the tweezers head will stagger, and makes that folder is is forbidden; In addition, because the tweezer folder is plates, so rigidity is little, that holds is not tight, therefore influences medical worker's accurate operation.

The purpose of this utility model is to improve the shortcoming of prior art and the tweezers that a kind of rigidity is big, clamping is accurate is provided.

For achieving the above object, this utility model is taked following design: tweezers are to be that pointed plates bending forms by two, and its knee has elasticity, tweezers two tweezers folders inner surface, and being provided with promptly increases by two tweezers folder rigidity and can make tweezer press from both sides the guider of accurate para-position again.This guider can be designed to lath-shaped, promptly be provided with one section lath along its length direction at the middle part of tweezer folder medial surface, its cross section is the T type, and is provided with one section two lath along its length direction in that the middle part of another tweezer folder medial surface is symmetric, and its cross section is the ∏ type.When using tweezers, what the lath on the two tweezers folder medial surface can sliding fit plugs together together.Designing it like this can increase the rigidity of tweezer folder, again forceps jaws is aimed at, to guarantee that the tweezers clamping accurately, effectively.Certainly, the lath that is positioned at two tweezers folder medial surface guider also can design like this, respectively is provided with two sections laths at two tweezers folder medial surface along its length direction, is plugged together but its cross section is the cover of ∏ type and its sliding fit.Also can ensure when using tweezers so accurately, effectively.Guider of the present utility model is design like this, on two tweezers folder medial surface, be provided with the raised ribs of at least one its rigidity of increase, be provided with a projection at tweezer folder inner surface simultaneously, be provided with a projection with holes at another tweezer folder inner surface, but the hole on this tweezer folder inner surface projection and another tweezer press from both sides plugging together of the corresponding and sliding fit of the projection of inner surface.Like this, described raised ribs can increase the rigidity of tweezer folder, and the projection of two tweezers folder medial surface can play the role of positioning, to guarantee the accurate para-position of tweezers head.Do not slide for guaranteeing that gripping object is stable, the tweezer chuck portion of these tweezers is provided with groove.

This utility model is simple in structure, and rigidity is big, and the clamping thing is accurately strong.

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment 1

As Fig. 2, Fig. 3, shown in Figure 4, tweezers 1 are to be that the plates bending of sharp type forms and knee has elasticity by two, and two tweezers folder, 11,12 medial surface of tweezers are provided with lath 111,121, but the plugging together together of lath 111 and lath 121 sliding fits.Two tweezer chuck portions are provided with groove 112,122.

Embodiment 2

As shown in Figure 5, tweezers are to be that the plates bending of sharp type forms and knee has elasticity by two, the difference of itself and embodiment 1 is that two tweezers folder, 21,22 medial surface of tweezers are equipped with two laths 211,221, but the plugging together together of lath 211 and lath 221 sliding fits.

Embodiment 3

As Fig. 6, Fig. 7, shown in Figure 8, tweezers 3 are to be that the plates bending of sharp type forms and knee has elasticity by two, the difference of itself and embodiment 1 is that two tweezers folder, 31,32 medial surface of tweezers 3 are provided with raised ribs 311,321, be provided with a convex cylindrical 312 at tweezer folder inner surface simultaneously, be provided with the projection 322 of a band circular hole at another tweezer folder inner surface, but being plugged on together of projection 322 sliding fits of described convex cylindrical 312 and band circular hole.

Claims

1, a kind of tweezers, it is to be that the plates bending of sharp type forms by two, and its knee has elasticity, it is characterized in that: two tweezers folder inner surface is provided with and promptly increases by two tweezers folder rigidity and can make tweezer press from both sides the guider of accurate para-position again.

2, a kind of tweezers according to claim 1, it is characterized in that: described guider is to be provided with one section lath at the middle part of tweezer folder medial surface along its length direction, its cross section is the T type, and be provided with one section two lath along its length direction in that the middle part of another tweezer folder medial surface is symmetric, its cross section is the ∏ type, plugs together together and the lath on the tweezer folder medial surface can sliding fit.
