Abstract
The invention relates to a nail puller used in department of orthopaedics.The nail puller comprises a fixing part in a U-shaped structure, wherein one end of the fixing part is connected with a main handle, the central position of a horizontal section of the fixing part is connected with a first clamping claw and a second clamping claw, the first clamping claw is in hinged connection with the second clamping claw, one end of the first clamping claw and one end of the second clamping claw are respectively connected with an auxiliary handle through a connecting rod, and a plurality of anti-slip teeth are arranged at jaws of the first clamping claw and the second clamping claw.When the nail puller is used, a doctor holds the main handle with hand and then pulls the auxiliary handle to achieve screw clamping performed by the first clamping claw and the second clamping claw, and the nail puller facilitates screw taking, is convenient to operate and facilitates smooth surgery performing.
Description
Technical field
The present invention relates to technical field of medical instrument, particularly relate to a kind of orthopaedics nail extractor.
Background technology
Medical skill, refer to that medical institutions and medical worker thereof are to diagnose and treat for the purpose of disease, disease is judged and eliminates a disease, alleviate the state of an illness, palliate the agonizing sufferings, improve function, diagnosis that extending life, help patient get well and take, remedy measures.
Orthopedics of Chinese Medicine is a science of research preventing and treating human body skin and flesh, muscles and bones, QI and blood, zang-fu differentiation damage and illness.Belong to the category such as " fracture complicated with infection ", " gold arrowhead " in ancient times.Undergraduate course has the different appellations such as " gold infections ", " synthetism ", " bonesetting ", " traumatology " in history.Orthopedics of Chinese Medicine is with a long history, people of all nationalities of China with wound illness long-term struggle create and grows up, and define abundant theoretical system, become an independent subject, being the important component part of Chinese medicine, the development with medical science of multiplying and being prosperous for the Chinese nation contributes.
When being currently performed bone surgery, bone-fracture patient is in performing the operation, and doctor adopts common screwdriver to be not easily taken out screw when knockout screw when screw hair, causes that operation is not smooth.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art, it is provided that a kind of orthopaedics nail extractor.
The present invention is achieved through the following technical solutions:
A kind of orthopaedics nail extractor, fixture including U-shaped structure, described fixture one end is connected with king lever, described fixture horizontal segment center is connected with the first gripper jaw, the second gripper jaw, it is articulated and connected between described first gripper jaw, the second gripper jaw, described first gripper jaw, second gripper jaw one end are connected with from lever respectively through connecting rod, described first gripper jaw, the second gripper jaw jaw place be provided with several anti-slop serrations.
As the preferred technical solution of the present invention, described first gripper jaw, between the second gripper jaw and connecting rod for being articulated and connected.
As the preferred technical solution of the present invention, described anti-slop serrations is triangular prism structure.
As the preferred technical solution of the present invention, described king lever is cased with Anti-slip cover.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is by arranging the first gripper jaw, the second gripper jaw, when so using, doctor's hand holds king lever, then pull and realize the first gripper jaw from lever, screw is clamped by the second gripper jaw, it is easy to the taking-up of screw, easy to operate, it is simple to being smoothed out of operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Refer to the structural representation that Fig. 1, Fig. 1 are the present invention.
A kind of orthopaedics nail extractor, including the fixture 1 of U-shaped structure, described fixture 1 one end is connected with king lever 2, wherein said king lever 2 is cased with Anti-slip cover 8, so can improve the comfortableness of taking.Described fixture 1 horizontal segment center is connected with first gripper jaw the 3, second gripper jaw 4, it is articulated and connected between described first gripper jaw the 3, second gripper jaw 4, for being articulated and connected between wherein said first gripper jaw the 3, second gripper jaw 4 and connecting rod 6, the connection from lever 7 so can be realized.
Described first gripper jaw the 3, second gripper jaw 4 one end is connected with from lever 7 respectively through connecting rod 6, the jaw place of described first gripper jaw the 3, second gripper jaw 4 is provided with several anti-slop serrations 5, wherein said anti-slop serrations 5 is in triangular prism structure, and such anti-slop serrations 5 can improve the skid resistance of clamping.When so using, doctor's hand holds king lever 2, then pulls and realizes first gripper jaw the 3, second gripper jaw 4 to screw clamping from lever 7, it is simple to the taking-up of screw, easy to operate, it is simple to being smoothed out of operation.
In describing the invention, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, for instance, it is possible to it is fixing connection, it is also possible to be removably connect, or integral；Can be mechanically connected, it is also possible to be electrical connection；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, it is possible to be connection or the interaction relationship of two elements of two element internals.For the ordinary skill in the art, it is possible to concrete condition understands above-mentioned term concrete meaning in the present invention.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
