The utility model is realized in this way a kind of nail taking out apparatus in orthopaedics is provided with
Fixed bracket；
Two sides are installed by welding with device fixing groove below fixed bracket, and the lower end of device fixing groove is equipped with fixing bolt；
Support bracket fastened top offers fluting, and fluting is interior to be fixed with lead screw by bearing, passes through worm screw on the outside of screw rod and connects
It is connected to fixed sliding block, the both sides of fixed sliding block are fitted with damping spring, are fixed with longitudinal lift lever among fixed sliding block, mention
Rising stem upper end end has been bolted rotating handle, and lift lever lower end is mounted with by bolt takes ailhead.
The utility model passes through the both sides bed body edge that fixed bracket can be fixed on patient, supporting & stablizing, and avoiding device shakes
It is dynamic, cause harm to the human body, lift lever and take ailhead can by screw thread rotation by way of bone nail taken out so that bone nail by
Power is uniform, will not cause to damage to human body because of overexerting, and filters out vibration when taking nail by damping spring, avoids to people
Body causes discomfort.The device takes out doctor readily by the bone nail of patient, and reduces the damage to patient, improves hand
Art efficiency.
Further, it takes ailhead diameter to be gradually increased from top to bottom, takes ailhead lower half portion to offer multiple longitudinal openings, take
Adjusting bolt has been threadably secured on the outside of ailhead.
The utility model can be adjusted the openings of sizes for taking ailhead lower end by adjusting bolt, convenient to different rulers
Very little bone nail is operated.
Further, interference fit is connected with stop sleeve among fixed sliding block, and lift lever is threadedly secured to support sleeve
Cylinder inside.
The utility model is attached by stop sleeve and lift lever, and the stability of lift lever can be improved, prevent
It shakes in lifting process.
Further, lead screw is welded with rotating wheel in fixed stent outer.
The utility model can control lead screw rotation by rotating wheel, to drive fixed sliding block in fluting by worm screw
It moves left and right, adjustment is facilitated to take the lateral position of ailhead.
