Abstract
The utility model relates to a medical guide device, in particular to an orthopedic-use angle locating guide device. The guide device comprises a main sleeve pipe, an assistant sleeve pipe, a main fixing arm and an assistant fixing arm, wherein, the main sleeve pipe and the assistant sleeve pipe are respectively connected with the main fixing arm and the assistant fixing arm; the main sleeve pipe and the assistant sleeve pipe are arranged in the same plane; a dial is arranged at the extension end of the main fixing arm; the rotation center of the dial is hinged with the extension end of the assistant fixing arm; and a pointer is arranged at the extension end of the assistant fixing arm. Compared with the prior art, the guide device adopting the technical scheme has the advantage of simple structure, is convenient for operation, acquires the needed angle after the main sleeve pipe rotates relative to the assistant sleeve pipe, and can accurately beat two screws or Kirschner wires into the main sleeve pipe and the assistant sleeve pipe according to the angle determined by the main sleeve pipe and the assistant sleeve pipe.
Description
Technical field:
This utility model relates to a kind of medical guider, particularly a kind of orthopaedics angle orientation guider.
Background technology:
In the process of fracture internal fixation, often need two pieces of Kirschner wires or screw is angled squeezes into, clinical sleeve commonly used is a monotubular, can not accurately control the angle of two pieces of screws or Kirschner wire, needs to rely on patient's operating experience just can finish this operation.
The utility model content:
Goal of the invention of the present utility model is to overcome the deficiency of background technology and provides a kind of in the process of fracture internal fixation, the orthopaedics angle orientation guider of can be accurately Kirschner wire or drill bit being squeezed into by institute's required angle.
This utility model adopts following technical scheme:
A kind of orthopaedics angle orientation guider, comprise master collet, secondary sleeve, main fixed arm, secondary fixed arm, described master collet is connected with secondary fixed arm with main fixed arm respectively with secondary sleeve, this master collet and secondary sleeve place in the same plane, the elongated end of this main fixed arm is provided with graduated disc, and the centre of gyration of this graduated disc and the elongated end of described secondary fixed arm are hinged, and this elongated end is provided with pointer.
This utility model of employing technique scheme compared with prior art, its advantage is: simple in structure, easy to make, master collet obtains required angle after with respect to the telescopic rotation of pair, and the angle that two screws or Kirschner wire can accurately be determined by major and minor sleeve be squeezed into from master collet and secondary sleeve.
As a kind of preferred version of the present utility model, the centre of gyration of described graduated disc and the elongated end of described secondary fixed arm are hinged by bearing pin.
As a kind of preferred version of the present utility model, an end of described bearing pin is provided with screw thread, on this end of thread nut is housed.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
A kind of orthopaedics angle orientation guider is referring to accompanying drawing 1 and accompanying drawing 2, among the figure: master collet 1, main fixed arm 2, graduated disc 3, pointer 4, bearing pin 5, secondary fixed arm 6, secondary sleeve 7, screw thread 8, nut 9.
Master collet 1 is connected with secondary fixed arm 6 with main fixed arm 2 respectively with secondary sleeve 7, master collet 1 and secondary sleeve 7 place in the same plane, the elongated end of main fixed arm 2 is provided with graduated disc 3, the elongated end of the centre of gyration of graduated disc 3 and secondary fixed arm 6 is hinged by bearing pin 5, and the elongated end of secondary fixed arm 6 is provided with pointer 4.
The elongated end of the centre of gyration of graduated disc 3 and secondary fixed arm 6 is hinged by bearing pin 5.One end of bearing pin 5 is provided with screw thread 8, and nut 9 is housed on the screw thread 8.
When master collet 1 and secondary sleeve 7 are parastate, the zero graduation position of pointer 4 corresponding graduated discs 3, obtain required angle after the rotation of master collet 1 with respect to secondary sleeve 7, with nut 9 bearing pin 5 is locked when reaching required angle, the angles that two screws or Kirschner wire can accurately be determined by master collet 1 and secondary sleeve 7 be squeezed into from master collet 1 and secondary sleeve 7.
