Abstract

The utility model discloses auricular bone scissors for mallei, which comprise a forceps handle, a push rod and a forceps head. The forceps handle consists of a front forceps handle (6) and a rear forceps handle (5), the push rod comprises an upper push rod (4) and a lower push rod (3), the forceps head consists of a left forceps head (1) and a right forceps head (2), two ends of the upper push rod (4) are fixedly connected with the right forceps head (2) and the front forceps handle (6) respectively, two ends of the lower push rod (3) are fixedly connected with the left forceps head (1) and the rear forceps handle (5) respectively, the front forceps handle (6) is rotationally connected with the rear forceps handle (5), a hemispherical projection (11) is arranged at the end of the left forceps head (1), and the bottom surface of the hemispherical projection (11) matches with the end of the left forceps head (1). The auricular bone scissors for mallei can avoid injury to auditory meatus of patients when used in an auricular surgery.

Description

Ear is used the malleus bone scissors

Technical field

This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of ear is used the malleus bone scissors.

Background technology

Ear is a kind of apparatus commonly used in the operation with the malleus bone scissors, in the otology operation, makes to shear malleus and uses.

Present existing ear is used the malleus bone scissors; Push rod that comprises the pincers handle formed by preceding pincers handle and forceps major handle, forms by upper push-rod and lower push-rod and the binding clip of forming by left binding clip and right binding clip; The two ends of upper push-rod are fixedly linked with right binding clip and preceding pincers handle respectively; The two ends of lower push-rod are fixedly linked with left binding clip and forceps major handle respectively, and preceding pincers handle and forceps major handle are rotatedly connected.During actual the use, push rod and binding clip stretch in the auditory meatus, and the pincers handle is controlled left binding clip and right binding clip is made relative open and close through handling, thereby accomplishes the work of shearing malleus.Above-mentioned ear exists following defective with the malleus bone scissors: because the end of left binding clip is the plane, therefore exist corner angle certainly, and auditory meatus is very narrow and small, left binding clip damages auditory meatus in stretching into auditory meatus the time easily.

Summary of the invention

The technical problem that this utility model will solve provides a kind of ear that can avoid damaging auditory meatus and uses the malleus bone scissors.

In order to solve the problems of the technologies described above; This utility model provides a kind of ear to use the malleus bone scissors; Push rod that comprises the pincers handle formed by preceding pincers handle and forceps major handle, forms by upper push-rod and lower push-rod and the binding clip of forming by left binding clip and right binding clip; The two ends of upper push-rod are fixedly linked with right binding clip and preceding pincers handle respectively, and the two ends of lower push-rod are fixedly linked with left binding clip and forceps major handle respectively, and preceding pincers handle and forceps major handle are rotatedly connected; In the end of left binding clip the hemispherical protuberance is set, the bottom surface of hemispherical protuberance and the end of left binding clip match.

The ear of this utility model is used the malleus bone scissors, owing to be provided with the hemispherical protuberance in the end of left binding clip, and the end of the bottom surface of hemispherical protuberance and left binding clip matches; Therefore just there have not been corner angle in the end of left binding clip.In actual the use, left binding clip just can not damage auditory meatus in stretching into auditory meatus the time.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of this utility model is done further explain.

Fig. 1 is the main TV structure sketch map of the ear of this utility model with the malleus bone scissors;

Fig. 2 is the partial schematic diagram of overlooking after the amplification of Fig. 1.

The specific embodiment

Fig. 1 and Fig. 2 combine to have provided a kind of ear and use the malleus bone scissors; Push rod that comprises the pincers handle formed by preceding pincers handle 6 and forceps major handle 5, forms by upper push-rod 4 and lower push-rod 3 and the binding clip of forming by left binding clip 1 and right binding clip 2; The two ends of upper push-rod 4 are fixedly linked with preceding pincers handle 6 with right binding clip 2 respectively; The two ends of lower push-rod 3 are fixedly linked with forceps major handle 5 with left binding clip 1 respectively, and preceding pincers handle 6 is rotatedly connected with forceps major handle 5.The all same prior art of said structure, the also same prior art of its method for using.

In the end of left binding clip 1 hemispherical protuberance 11 is set, the end of the bottom surface of hemispherical protuberance 11 and left binding clip 1 matches.

At last, it is also to be noted that what more than enumerate only is a specific embodiment of this utility model.Obviously, this utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of this utility model all should be thought the protection domain of this utility model.

Claims

1. ear is used the malleus bone scissors; Push rod that comprises the pincers handle formed by preceding pincers handle (6) and forceps major handle (5), forms by upper push-rod (4) and lower push-rod (3) and the binding clip of forming by left binding clip (1) and right binding clip (2); The two ends of upper push-rod (4) are fixedly linked with right binding clip (2) and preceding pincers handle (6) respectively; The two ends of lower push-rod (3) are fixedly linked with left binding clip (1) and forceps major handle (5) respectively, and said preceding pincers handles (6) are rotatedly connected with forceps major handle (5); It is characterized in that: in the end of said left binding clip (1) hemispherical protuberance (11) is set, the end of the bottom surface of said hemispherical protuberance (11) and left binding clip (1) matches.
