Description

Hook tweezer

Technical field

The present invention relates to the field of medical instrument technology, in particular to a kind of hook tweezer.

Background technique

Need to use tack in tympanitis operation, alligator forceps, the instruments such as stripper come separated, hook is drawn, clamping is different Tissue.Space is small in ear, and it is very inconvenient ceaselessly to replace instrumentation in operation, needs one there is separation, hook to draw, folder The instrument held.

Summary of the invention

It is an object of the present invention to provide a kind of hook tweezers, can separate in ear, hook draws, clamps different tissues.

Based on the above issues, present invention provide the technical scheme that

Tweezer, including two elastic arms and two tweezer points are hooked, described two elastic arm one end are connected with each other, described two bullets The other end arranged for interval of property arm keeps described two elastic arms V-shaped, and the end of the elastic arm is arranged in the tweezer point, described Tweezer point is connect in obtuse angle with the elastic arm, and the medial surface of the tweezer point is equipped with several clamping teeth portion.

In one of them embodiment, the elastic arm includes V-shaped tweezer handle and the tweezer handle end is arranged in The width of tweezer arm, the tweezer arm is less than the tweezer handle.

In one of them embodiment, the medial surface of at least one tweezer handle is equipped with limited block.

In one of them embodiment, the width of the tweezer arm is gradually reduced from the tweezer handle to tweezer point direction.

In one of them embodiment, the width of the tweezer point is gradually reduced by the outside end of the elastic arm.

In one of them embodiment, the inner end width of the tweezer point is 0.3~0.8mm.

In one of them embodiment, the outer end of the tweezer point is in arc surface.

In one of them embodiment, the diameter of the outer end of the tweezer point is 0.05~0.08mm.

In one of them embodiment, the angle between the tweezer point and the elastic arm is 120~150 degree.

In one of them embodiment, after described two tweezer points are close to fitting, the medial surface phase of described two tweezer points Mutually engagement.

Compared with prior art, the invention has the advantages that

Using technical solution of the present invention, the tweezer point of the hook tweezer has the function of stripper and tack, tweezer point point when mediating Has the function of separation when opening, which can be used for the removing, separation and crawl of ear inner tissue, no replacement is required instrument, operation side Just, the fluency of operation is improved.

Detailed description of the invention

In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment Attached drawing be briefly described, drawings in the following description are only some embodiments of the invention, skill common for this field For art personnel, without creative efforts, it is also possible to obtain other drawings based on these drawings.

Specific embodiment

Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating The present invention and be not limited to limit the scope of the invention.Implementation condition used in the examples can be done according to the condition of specific producer Further adjustment, the implementation condition being not specified is usually the condition in routine experiment.

Be the structural schematic diagram of the embodiment of the present invention referring to Fig. 1-4, a kind of hook tweezer be provided, including two elastic arms 1 and Two tweezer points 2, two 1 one end of elastic arm are connected with each other, and the other end arranged for interval of two elastic arms 1 makes two elastic arms 1 in V The end of elastic arm 1 is arranged in type, tweezer point 2, wherein tweezer point 2 is connect in obtuse angle with elastic arm 1, is equipped in the medial surface of tweezer point 2 Several clampings teeth portion 2-1.

Clamping teeth portion 2-1 can be used various shape, in this example, after two tweezers points 2 are close to fitting, two tweezer points 2 it is interior Side intermeshing, setting clamping teeth portion 2-1 make the tissue in the firm clamping ear of tweezer point 1.

Angle between tweezer point 2 and elastic arm 1 is 120~150 degree, preferably 135 degree.The length of tweezer point be 2.4~ 2.6mm。

In this example, elastic arm 1 includes V-shaped tweezer handle 1-1 and tweezer arm 1-2, tweezer arm 1-2 that the end tweezer handle 1-1 is arranged in Width be less than tweezer handle 1-1.

The width of tweezer arm 1-2 is gradually reduced from tweezer handle 1-1 to sharp 2 directions of tweezer, and the lateral surface of tweezer arm 1-2 is cambered surface.One The medial surface of a tweezer handle 1-1 is equipped with limited block 3, to control the spacing of clamping.

It is equipped with non-slip texture 4 in the lateral surface of tweezer handle 1-1, in order to operate when performing the operation in ear, avoids slipping.

The width of tweezer point 2 is gradually reduced by the outside end tweezer arm 1-2, and the inner end width of tweezer point 2 is 0.3~0.8mm, excellent It is selected as 0.5mm.The outer end of tweezer point 2 is in arc-shaped, and the diameter of outer end is 0.05~0.08mm, preferably 0.06mm.Tweezer The shape and structure of point 2 has the function of stripper and tack convenient for removing, Gou La ear inner tissue.

The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art It is to can understand the content of the present invention and implement it accordingly, it is not intended to limit the scope of the present invention.It is all according to the present invention The equivalent transformation or modification that Spirit Essence is done, should be covered by the protection scope of the present invention.
