Abstract
The utility model discloses a medical instrument for fracture fixation. The utility model can replace different diameters of jaws according to different thickness of bones, the instrument has a mechanism for adjusting the splaying angle of a fixed jaw, and because of the side pressurization fixation, the fracture part can be put in the bone holding fixer after segmental periostea at fracture point are peeled off, thus shortening operation time, avoiding negative damnification, and increasing bone healing speed.
Description
This utility model belongs to the improvement of fracture fixation medical apparatus and instruments.
When extremity fracture resets internal fixation, must use and hold the temporary fixed fracture end of bone anchor, then methods such as reuse steel plate, steel wire or pulp cavity pin are fixed.The bone anchor of holding at present both at home and abroad commonly used must extensively be peeled off the fracture periosteum and can be lowered to during use, existingly like this causes a danger of paying damage, has prolonged operating time again, has also influenced knitting simultaneously.The former bone anchor of holding belongs to upper and lower pressurization, because of the compressing steel plate, be unfavorable for that compression steel plate carries out the epiphysis pressurization, is pressed in fracture because of the former dewclaw of holding bone anchor again in the time of fixedly, can't see the alignment situation of fracture, also occur sometimes continuing to bore the situation of holding bone anchor after the saturating offside cortical bone of bit drills.
As figure this utility model is by jaw (1), left side pincers strand (2), right pincers strand (3), screw rod (6), nut (5), top ferrum (7), leaf spring formations such as (4).Jaw (1) can be made different-diameter, and end has the axle of insertion (8).On left side pincers strand (2), right pincers strand (3) front end face, a hole is arranged, affixed by screw and jaw (1), and can change at any time.Screw rod (6), nut (5), top ferrum (7) constitute reconciles fixed mechanism, reconciles the opening angle of regular jaw (1), and leaf spring (4) becomes to make by its elastic type to be held bone anchor and open automatically.
This utility model can be changed the jaw of different-diameter size according to the thickness difference of bone, is that the side adds press fit because this holds bone anchor, need only cleavage fracture place part periosteum can put into and hold bone anchor, thereby shortened operating time, avoided a pair damage, quickened the bone connection speed.Bone holder compressed steel plate not because of fixedly the time then helps compression steel plate and carries out the fracture end pressurization again, can be clear that the fracture alignment situation again, gets into the situation of holding the bone anchor pawl when also having avoided simultaneously boring.
Embodiment of the present utility model is following finishing:
Jaw (1) diameter is respectively 17mm, 25mm, 30mm, tooth can be done across or herringbone in case hold the bone slippage in the jaw, the end of jaw inserts on the axle (8) a top wire hole (9), left side pincers labour (2), on right pincers strand (3) front end face a hole being arranged is that jaw (1) is mated fixing usefulness.Left side pincers strand (2) its end has the wide 8mm slot of a dark 22mm, the terminal hinge joint of right pincers strand (3) has the screw rod (6) of band nut (5), top ferrum (7), knurled nut (5) and screw rod (6) threaded engagement, the other end of screw rod (6) can be put into the slot of left side pincers strand (2), drive top ferrum (7) by swivel nut (5) and adjust regular jaw (1) opening angle, leaf spring (4) is made by two spring steel plates, one end is fixed on left side pincers strand (2), the right pincers strand (3) by screw, the other end is riveted together, and becomes by its elastic type jaw is opened automatically.
Claims (2)
1, hold bone anchor by what jaw, left side pincers strand, right pincers thigh were formed, it is characterized in that:
A. the end at jaw has the axle of insertion.
B. on left side pincers thigh, right pincers strand front end face, a hole is arranged.
C. in burst rear end hinge joint of the right side pincers nut, top ferrum, screw rod are arranged.
D. in a pincers burst rear end, a left side one slot is arranged.
2, the bone anchor of holding according to claim 1 is characterized in that making the automatic open leaf spring of jaw between left pincers thigh, the right pincers thigh.
