The beneficial effects of the utility model are that its clamp piece is provided with the joint of flexible activity, can adjust flexibly angle according to doctor's requirement, prevents that rongeur from stopping doctor's sight line, reduces operating difficulty.And, arrange on clamp piece and sting the bone tooth, sting the bone tooth and can increase friction, prevent articulated rongeur generation slip patient harm.It also can accurately open or be closed, can effectively avoid the patient is caused excessive damage.
Description of drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model; Fig. 2 be Fig. 1 be A to the structure for amplifying schematic diagram.
1 first clamp handle in figure, 2 second clamp handles, 3 second connectors, 4 first connectors, 5 second clamp pieces, 6 first clamp pieces, 7 bearing pins, 8 pointers, 9 first magnetic piece, 10 second magnetic piece, 11 adjustment rings, 12V shape cutter, 13 poles, 14 rotating seats, 15 jacks, 16 pins, 17 screw rods, 18 nuts, 19 first pull bars, 20 second pull bars, 21 handles.
The specific embodiment
As shown in Figure 1, articulated rongeur described in the utility model comprises the first clamp handle 1 and the second clamp handle 2.The first clamp handle 1 is hinged by bearing pin 7 and the second clamp handle 2.One end of the front end of the first clamp handle 1 and the first connector 4 is hinged, and the other end of the first connector 4 and the first clamp piece 6 are hinged.One end of the front end of the second clamp handle 2 and the second connector 3 is hinged, and the other end of the second connector 3 and the second clamp piece 5 are hinged.Pole 13 is installed on bearing pin 7.Rotating seat 14 is installed on pole 13, and rotating seat 14 only can rotate relative to pole 13.Be provided with jack 15 in rotating seat 14.The interior installation screw rod 17 of jack 15.Screw rod 17 is connected and fixed by pin 16 with jack 15.The nut 18 that is threaded on screw rod 17, the outer end mounting knob 21 of screw rod 17.Nut 18 is hinged with an end of the first pull bar 19 and the second pull bar 20 respectively, and the other end of the first pull bar 19 and the second pull bar 20 is hinged with the first clamp handle 1 and the second clamp handle 2 respectively.Arrange on the second clamp piece 5 to arrange on V-arrangement cutter 12, the first clamp pieces 6 and sting the bone tooth, sting the bone tooth corresponding with V-arrangement cutter 12.The described bone tooth of stinging can increase friction between the first clamp piece 6 and skeleton, prevents from because the relative skeleton of articulated rongeur slides, the patient being damaged in operation process.By swing handle 21, screw rod 17 driven rotary seats 14 are rotated relative to pole 13, thereby, nut 18 is moved along screw rod 17, finally reach the first clamp handle 1 and the second clamp handle 2 are accurately opened or closed purpose.If need described articulated rongeur open fast or when closed, only need pin 16 is taken out, rotating seat 14 separated with screw rod 17 get final product.
Sting door-hinge side V-arrangement bone groove when operation carrying out the spinal column single open-door, the second clamp piece 5 and the first clamp piece 6 are opened bite skeleton, and firmly clamp the first clamp handle 1 and the second clamp handle 2, make in the V-arrangement cutter 12 incision skeletons of the second clamp piece 5 to get final product.State in process at hands, can adjust the position of the second connector 3, the first connector 4, the second clamp piece 5 and the first clamp piece 6 according to practical situation, prevent that hands from stating the sight line that the second connector 3 in process, the first connector 4, the second clamp piece 5 and the first clamp piece 6 are blocked the doctor.
Open for convenience the second clamp piece 5 and the first clamp piece 6, as shown in Figure 1, the first magnetic piece 9 can be set in the inboard of the first clamp handle 1, the periphery of the second clamp handle 2 is installed adjustment ring 11, adjustment ring 11 can be rotated relative to the second clamp handle 2, the second magnetic piece 10, the second magnetic piece 10 are set corresponding with the first magnetic piece 9 on adjustment ring 11.When need with the second clamp piece 5 and the first clamp piece 6 separately the time, rotatable adjustment ring 11, as shown in Figure 1, make the second magnetic piece l0 relative with the first magnetic piece 9, the magnetic pole corresponding due to the second magnetic piece 10 and the first magnetic piece 9 is identical, therefore the first clamp handle 1 and the second clamp handle 2 are opened, thereby with the second clamp piece 5 and the first clamp piece 6 separately the time.
For making the doctor can be well understood to the degree that the second clamp piece 5 and the first clamp piece 6 clamp, as shown in Figure 1, can scale be set arranging on bearing pin 7 on pointer 8, the second clamp handles 2.When the second clamp piece 5 and the first clamp piece 6 clamping, just can understand the clamping degree of the second clamp piece 5 and the first clamp piece 6 according to the scale of pointer 8 indications.
