Description

Rongeur

Technical Field

The utility model relates to the technical field of medical instruments, in particular to rongeur.

Background

Rongeur is a common medical appliance, and is mainly suitable for treating bony spur at the joint connecting part of a human body. The existing rongeur has the following defects: rongeur is mostly ordinary industrial pincers on the market, including the rongeur body (binding clip) and rongeur handle, this binding clip width is too big, need use great power when the pincers cutting rib, and the pincers are mostly straight design, need exert oneself in the vertical direction when exerting oneself in dissecting, bring the difficulty and do not have very sharp tooth mouth for dissecting the operation, clinical practical nurse operates to get up very hard, must use very big dynamics, awkward.

In view of the above-mentioned problems and disadvantages, there is a need for new improvements in the design of existing rongeur.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present invention provides a rongeur.

The technical scheme adopted by the utility model for solving the technical problem is as follows:

the utility model provides a rongeur, includes the pincers body and with the handle that the pincers body is connected which characterized in that: the jaw of the pliers body is of a continuous three-section type shearing structure.

As a further improvement to the above solution, the jaw comprises a sharp mouth section, a sawtooth section and a thread cutting section, and the sharp mouth section is connected with the thread cutting section through the sawtooth section.

Furthermore, the sharp mouth section is composed of a plurality of transversely arranged cutting edges, and a first gap is formed between every two adjacent cutting edges.

Furthermore, the sawtooth section comprises a plurality of cutting edges arranged transversely, and a second gap is formed between every two adjacent cutting edges.

Further, the second gap is larger than the first gap.

Further, the shear line segment is formed by a transversely continuous blade.

Furthermore, a connecting part is arranged between the forceps body and the handle.

Furthermore, the connecting portion includes first linkage segment, second linkage segment, third linkage segment and fourth linkage segment, the one end of first linkage segment with the one end of second linkage segment is articulated, the one end of third linkage segment with the one end of fourth linkage segment is articulated, the other end of first linkage segment with the other end of third linkage segment is articulated and with the handle links to each other, the other end of second linkage segment with the other end of fourth linkage segment is articulated and with the pincers body links to each other.

Furthermore, the inner side of the handle is fixedly connected with a bone rongeur elastic sheet through a screw.

In addition, the handle is provided with a limiting piece, and the handle on one side of the limiting piece is provided with anti-skidding grains.

The utility model has the beneficial effects that: the rongeur provided by the utility model comprises a plier body and a handle connected with the plier body, wherein a jaw of the plier body is a continuous three-section type shearing structure consisting of a sharp mouth section, a sawtooth section and a trimming section, and the sharp mouth section is connected with the trimming section through the sawtooth section.

Detailed Description

Referring to fig. 1-5, a rongeur 10 includes a pliers body 100 and a handle 200 connected to the pliers body 100, wherein the jaws 110 of the pliers body 100 are of a continuous three-stage cutting structure. The jaw 110 includes a tip section 111, a saw tooth section 112 and a trimming section 113, wherein the tip section 111 is connected with the trimming section 113 through the saw tooth section 112. The existing design structure has no sharp tooth mouth, the operation of clinical and practical medical care personnel is very laborious, the aim can be achieved only by using great force, and the use is inconvenient; the improved jaw of the utility model has sharp tooth mouth, thus the nurse in clinical practice can operate with the least force with little force.

As shown in fig. 4 and 5, the tip section 111 is formed by a plurality of transversely arranged cutting edges with first gaps 114 between adjacent cutting edges. The serrated section 112 is formed by a plurality of transversely arranged blades with a second gap 115 between adjacent blades. The second gap 115 is larger than the first gap 114. The line section 113 is formed by a transversely continuous cutting edge. So can guarantee to have sharp tooth mouth, the validity that the structure can guarantee the operation is cuted to the syllogic in addition.

A connecting part 300 is arranged between the forceps body 100 and the handle 200. The connecting portion 300 includes a first connecting section 301, a second connecting section 302, a third connecting section 303 and a fourth connecting section 304, wherein one end of the first connecting section 301 is hinged to one end of the second connecting section 302, one end of the third connecting section 303 is hinged to one end of the fourth connecting section 304, the other end of the first connecting section 301 is hinged to the other end of the third connecting section 303 and connected to the handle 200, and the other end of the second connecting section 302 is hinged to the other end of the fourth connecting section 304 and connected to the forceps body 100. In use of the rongeur 10, the hinge joints will extend outwardly due to the hinge structure. The inner side of the handle 200 is fixedly connected with a rongeur elastic sheet 210 through a screw.

The handle 200 is provided with a limiting piece 220, and the handle 200 on one side of the limiting piece 220 is provided with an anti-skid grain 230. The limiting piece 220 and the anti-slip pattern 230 are arranged to effectively limit the hand slip of the user.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model.
