Description
(1) technical field under
This utility model relates to a kind of medical pincers, particularly a kind ofly is suitable for two nail reduction of the fracture pincers that miscellaneous fracture resets.
(2) background technology
When fracture patient carries out the reduction of the fracture, operations such as the two ends of fracture need being strutted, compress, lift, reset and be temporary fixed.Need a kind of clamping firmly, accurate positioning, wound is little, and can carry out the reduction forceps of various reset operations accurately and easily.At present, the reduction of the fracture of clinical practice pincers are mainly " wolf tooth pincers ", and the person that is only applicable to the tubular bone fracture is very difficult for the reduction of the fracture at positions such as pelvis.
(3) summary of the invention
This utility model is in order to overcome above deficiency, two nail reduction of the fracture pincers of reset operations such as providing a kind of and can strut accurately and easily, compress, lift, reset.
This utility model is realized by following measure:
The movable compressed rod that struts that has a sawtooth of fixing wherein is fixed with on the leader and can strutting the gear that rotates on the compressed rod between the two nail reduction of the fracture pincers of the present utility model, two handles; The lower end of jaw is threaded, and is with rotatable fixed muffle on the screw thread; The upper end of jaw is a screw girdle device, and the screw girdle device has two bayonet sockets that can open and close, and fixes a spring between two bayonet sockets, and bayonet socket has the groove that matches with screw cap.
Two nail reduction of the fracture pincers of the present utility model are by handle, and gear struts compressed rod, Movable joint, and screw girdle device, fixed muffle etc. partly constitute.Transmitting gear by strutting compressed rod, can make the arbitrarily angled opening of reduction forceps, remain silent, to adapt to the operation of different angles; Simultaneously, reduction forceps is controlled at very accurately on the angle.
When fixed muffle rotational slide to the back-end, by the spring tension between the bayonet socket, the bayonet socket port of jaw front end magnifies, and screw cap can snap in the bayonet socket easily.The rotational slide of fixed muffle forward end can be tightened up the front port of bayonet socket, thus the chucking screw.
During use, adopt two screws, pierce the fixed fracture line both sides that need reset in advance, screw cap astragalus matter leaves the gap of 2-3mm.Swing pinion, the distance of regulating two jaws equates with the spacing of two screws.Be rotated down fixed muffle, two bayonet sockets of screw girdle device are opened, screw cap is snapped in the bayonet socket of screw girdle device front end, rotate up fixed muffle, make screw and reduction forceps strong bonded, at this moment, strutting or compress skeleton that reduction forceps can drive the fracture line both sides struts or compresses, cooperate twisting, pull lift action again, can be with the reduction of the fracture of Any shape, and can be temporary fixed.
The beneficial effects of the utility model are, it is firm to have a clamping, accurate positioning, and wound is little, and can carry out various reset operations accurately and easily, is fit to the reduction of the fracture of different shape.

Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of screw girdle device
Among the figure, 1 handle, 2 gears, 3 strut compressed rod, 4 Movable joints, 5 screw girdle devices, 6 fixed muffles, 7 springs, 8 bayonet sockets
(5) specific embodiment
Accompanying drawing is the concrete structure sketch map of present embodiment.Be by handle (1), gear (2) struts compressed rod (3), Movable joint (4), and screw girdle device (5), fixed muffle (6) waits part to constitute.
On the handle (1), the other end is fixed on another handle (1) by gear (2) activity therein in the end hinge joint that struts compressed rod (3); Strut on the compressed rod (3) and have sawtooth, sawtooth matches with gear.Swing pinion can be regulated the angle of reduction forceps jaw by strutting compressed rod.
The lower end of jaw is cylindrical, and is threaded, and is with rotatable fixed muffle (6) on the screw thread; The upper end of jaw is a screw girdle device (5), screw girdle device (5) has two bayonet sockets that can open and close (8), the lower end of two bayonet sockets is hinged together by a Movable joint, fixes a spring (7) between two bayonet sockets (8), and bayonet socket has the groove that matches with screw cap.Screw cap can snap in the bayonet socket (8), and by rotation fixed muffle (6) screw cap is fixed.
Claims (1)
1. the two nail reduction of the fracture clamps, between two handles (1) movable fix one have a sawtooth strut compressed rod (3), wherein be fixed with on the leader and can strutting the gear (2) that rotates on the compressed rod, it is characterized in that: the lower end of jaw is threaded, and is with rotatable fixed muffle on the screw thread; The upper end of jaw connects a screw girdle device (5), and screw girdle device (5) has two bayonet sockets that can open and close (8), fixes a spring (7) between two bayonet sockets (8), and bayonet socket has the groove that matches with screw cap.
