Abstract
The utility model provides a sighting device for orthopedic surgery operations and particularly relates to the technical field of medical instruments. A first arc connecting support (1) and a second arc connecting support (2) are inserted in a connecting knob sleeve piece (8) in an intersecting mode. A drive gear (10) is arranged in the connecting knob sleeve piece (8), connected between the first arc connecting support (1) and the second arc connecting support (2) in a clamped mode, and meshed with arc internal teeth (11) in a groove between the first arc connecting support (1) and the second arc connecting support (2). The drive gear (10) is connected with an adjusting knob (9) at the upper end of the connecting knob sleeve piece (8). The sighting device is simple in structure, the single knob is matched with the gear, the left arc support and right arc support are controlled synchronously, the security coefficient is high, operation is convenient, and the safety of the operations is ensured.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to bone surgery sight.
Background technology
Due to neck of femur, the capable screw of femur intertrochanteric fracture and pegboard systems fixedly time, first to squeeze into neck of femur guide pin, and beat guide pin, be mainly to control collodiaphyseal angle and top rake, at present clinically the collodiaphyseal angle of guide pin is controlled to oneself and have accurate, easy sighting device, and still rest on the basis of micro-judgment for the control of top rake, some the existing most complicated operations of device that can control top rake, effect is imprecise, thereby can not well apply clinically.While using clinically traditional method to squeeze into guide pin, the control shortage bone mark due to top rake, becomes operation difficulties, and side position fluoroscopy during operation relative complex, definition is not good enough yet, so Chang Yinwei adjusts top rake and wastes a lot of time, operation risk increases greatly.Secondly because fracture is loose, partially before with partially after top rake be also to cause the postoperative screw major reason that cutting passes to neck of femur.
In the patent that has been 200520134489.8 at application number for the problems referred to above, solve, this patent adopts two screws to intersect fixing mode to connect, this connected mode is when operating, two screws must be unclamped simultaneously and just regulation can be carried out, easily there is operate miss, make guide pin destroy its hetero-organization, dangerous.
Summary of the invention
The purpose of this utility model is to provide bone surgery sight, and it is simple in structure, adopts single knob mate gear, and left and right two arc supports are carried out to Synchronization Control, and safety coefficient is higher, and more convenient operation, has guaranteed the safety of operation.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises the first circular arc link 1, the second circular arc link 2, the first hold-down nut 3, positioning needle 4, the second hold-down nut 5, the sleeve pipe 6 of threading a needle, guide pin 7, the left side of the first described circular arc link 1 is interspersed with positioning needle 4, positioning needle 4 is fixed by the first hold-down nut 3, the right side of the second described circular arc link 2 is interspersed with the sleeve pipe 6 of threading a needle, the thread a needle inside of sleeve pipe 6 is provided with guide pin 7, the sleeve pipe 6 of threading a needle is fixed by the second hold-down nut 5, and it also includes and connects knob external member 8, adjusting knob 9, driven wheel 10, the first described circular arc link 1, staggered being plugged on of the second circular arc link 2 connects in knob external member 8, connects knob external member 8 inside and is provided with driven wheel 10, and driven wheel 10 is connected to the first circular arc link 1, between the second circular arc link 2, and with the first circular arc link 1, arc inner tooth 11 engagements in groove in the middle of the second circular arc link 2, described driven wheel 10 connects with the adjusting knob 9 that is connected knob external member 8 upper ends.
This utility model operation principle: by manual rotation adjusting knob 9, make driven wheel 10 and adjusting knob 9 synchronous rotaries, the turning effort of driven wheel 10 drives the first circular arc link 1, the second circular arc link 2 to carry out telescopic adjustment.
The utlity model has following beneficial effect: it is simple in structure, adopt single knob mate gear, left and right two arc supports are carried out to Synchronization Control, safety coefficient is higher, and more convenient operation, has guaranteed the safety of operation.
Accompanying drawing explanation:
Fig. 1 is this utility model structural representation;
Fig. 2 is arc inner tooth 11 structural representations;
Fig. 3 connects knob external member 8 sectional views.
The specific embodiment:
Referring to Fig. 1-3, this specific embodiment by the following technical solutions: it comprises the first circular arc link 1, the second circular arc link 2, the first hold-down nut 3, positioning needle 4, the second hold-down nut 5, the sleeve pipe 6 of threading a needle, guide pin 7, the left side of the first described circular arc link 1 is interspersed with positioning needle 4, positioning needle 4 is fixed by the first hold-down nut 3, the right side of the second described circular arc link 2 is interspersed with the sleeve pipe 6 of threading a needle, the thread a needle inside of sleeve pipe 6 is provided with guide pin 7, the sleeve pipe 6 of threading a needle is fixed by the second hold-down nut 5, and it also includes and connects knob external member 8, adjusting knob 9, driven wheel 10, the first described circular arc link 1, staggered being plugged on of the second circular arc link 2 connects in knob external member 8, connects knob external member 8 inside and is provided with driven wheel 10, and driven wheel 10 is connected to the first circular arc link 1, between the second circular arc link 2, and with the first circular arc link 1, arc inner tooth 11 engagements in groove in the middle of the second circular arc link 2, described driven wheel 10 connects with the adjusting knob 9 that is connected knob external member 8 upper ends.
Described the first circular arc link 1, the arc inner tooth 11 in the second circular arc link 2 are corresponding, and not in the same side.
This specific embodiment operation principle: by manual rotation adjusting knob 9, make driven wheel 10 and adjusting knob 9 synchronous rotaries, the turning effort of driven wheel 10 drives the first circular arc link 1, the second circular arc link 2 to carry out telescopic adjustment.
