End is provided with the second distraction plate, and the direction of the first distraction plate and the second distraction plate is identical, and the distraction surface of the first distraction plate with
The distraction surface of second distraction plate mutually deviates from.
Above-mentioned operation on vertebra is strutted tissue forceps and is with drawing, and the device for being adjustable two tong arms opening is hinged the
The pin shaft of one tong arm and the second tong arm is provided in the rear end of the first tong arm and the second tong arm and holds pincers circle, on the first tong arm
Equipped with fixed tooth, fixing groove is equipped on the second tong arm, fixed tooth and fixing groove are cooperatively connected.
Above-mentioned operation on vertebra struts tissue forceps with drawing, and the device for being adjustable two tong arms opening is phase interworking
The gear slider device and rack gear of conjunction, first tong arm are connected on rack gear, and the second tong arm is connected on gear slider device.
Above-mentioned operation on vertebra struts tissue forceps with drawing, and the gear slider device includes sliding shoe and is arranged in cunning
Gear inside motion block, the wheel and rack are meshed, and are equipped on gear and shake the hand with what moving gear rotated.
It is that the width of first distraction plate is 3cm, length is 7-that above-mentioned operation on vertebra, which struts tissue forceps with drawing,
8cm, the width of second distraction plate is 1.5cm, length is 4-5cm.
Compared with the prior art, the beneficial effects of the utility model are: the utility model is in the first tong arm and the second tong arm
Upper setting is adjustable the device of two tong arms opening, the first distraction plate is arranged in the front end of the first tong arm, before the second tong arm
The second distraction plate is arranged in end, keeps the direction of the first distraction plate and the second distraction plate identical, in operation on vertebra operating process, the
The distraction surface of the distraction surface of one distraction plate and the second distraction plate is contacted with the musculature around vertebrae, by vertebrae two sides
Musculature drawing struts, and operative incision is supportted greatly, thereby realizes and carries out in various degree to vertebrae two sides musculature
Drawing struts, and avoids unnecessary wound caused by due to the drawing of same degree struts.Meanwhile the utility model avoids and makes
Carry out continuous traction with manpower, simple for structure compact, easy to operate, surgical field of view is big, it can be ensured that operation on vertebra it is normal into
Row.
