Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of rongeur.
Background technique
Rongeur is a kind of neurosurgery, the common surgical instrument of orthopaedics, some people's bone windows are too when doing operation of opening cranium
Small, surgical field of view is inadequate, needs to be expanded with rongeur bone window, but the skull of many people is not only thick but also hard, is with traditional rongeur
It is very difficult to sting, it the difficulty of operation greatly increased, also will increase the risk of operation if stinging firmly by force.Currently, facing
Rongeur used on bed is mainly made of tong arm, spring leaf, connecting shaft and binding clip, and this rongeur is grasped when being engaged sclerotin
It causes high effort for, increases work difficulty to medical worker.
Summary of the invention
Based on the above issues, it is an object of that present invention to provide easy to operate, time saving and energy saving when a kind of progress sclerotin occlusion.
In view of the above problems, providing following technical solution: a kind of rongeur, including the first tong arm, the second tong arm, connection
Axis and binding clip, further include the driving mechanism for driving binding clip to be engaged or open, and the driving device includes shell, is located at shell
On power switch, be located at the intracorporal telescope motor of shell, power supply, circuit board and the linkage being connected with telescope motor, institute
It states housing forward end and is equipped with and connect respectively with the middle section of the first tong arm and the middle section of the second tong arm in the first hinged linking arm and second
Connect arm, the linkage include respectively with the end of the first tong arm and the end of the second tong arm in the first hinged articulated slab,
Second articulated slab and link block for connecting the first articulated slab and the second articulated slab, first articulated slab and second hinged
Plate is swingable with respect to link block, and the motor shaft of the telescope motor is connected with link block, and the rear end of the shell is equipped with for holding
The handle held, the handle inside are equipped with the button for controlling telescope motor, and the side of the button towards handle is equipped with
Pressure spring.
In above structure, when needing to expand bone window using the present invention, startup power supply switch holds handle, Continued depression is pressed
The motor shaft of button, telescope motor inwardly retracts, and motor shaft drives the first articulated slab and the second articulated slab to swing towards housing direction,
To drive the first tong arm to squeeze in opposite directions with the second tong arm, binding clip is driven to be engaged, button more to handle Inner extrusion, stretches
The stroke of the motor shaft retraction of motor is longer, and the bite force of binding clip is bigger；After bone window expands, release button, button passes through bullet
While spring resets, the motor shaft of telescope motor is protruding, so that the first articulated slab and the second articulated slab drive the first tong arm
It is resetted with the second tong arm, binding clip unclamps.Enable to binding clip more strong and flat when being engaged by the way that driving mechanism is arranged
