Utility model content
In consideration of it, the utility model, which provides a kind of fixed angle single-chamber, bores guider, to assist doctor to carry out screw into nail,
To reduce operation risk.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of fixed angle single-chamber bores guider,
It includes straight-bar, spanner and handle.The straight-bar is mutually fixed with handle, is equipped with through hole at the middle part of straight-bar, the spanner is worn
Through hole and hinged with straight-bar is crossed, the straight-bar is fixed with guide sleeve far from one end of handle, a cavity is equipped in guide sleeve, in cavity
It is mounted with a guider that can be slided along cavity inner wall, push rod is additionally provided with above straight-bar, one end of the push rod and the guiding
Device is hinged, and the other end is hinged with spanner upper end.
Further, it is additionally provided with a waist type groove in the middle part of the push rod, a groove is correspondingly arranged on straight-bar, is filled in waist type groove
Equipped with a pin, which is detachably mounted in groove.
Further, it is additionally provided with an annular projection between the push rod and the hinge joint and the pin of spanner, in pin
Spring is equipped between annular projection.
Further, the guide sleeve has the fixed part that is connected with straight-bar, and with the integrally formed first set of fixed part
Pipe portion, the end of the first set pipe portion are additionally provided with one group of stress slot.
Further, the first set pipe portion and straight-bar are in tilted layout, and inclination angle is 10-15 °.
Further, the guider have can along cavity inner wall slide the second cannula portion, and with the second casing
The interconnecting piece that portion mutually fixes and is hinged with push rod.
The utility model has the beneficial effects that the utility model provides a kind of single-chamber drilling director of fixed angle, lead to
Crossing manipulation spanner drives push rod to improve the positioning and precision of drilling so that guider slides in guide sleeve.The utility model tool
There is the advantages of easy to use, accurate positioning, and structure is simple, easily operated, while greatly reducing the risk of operative failure.
Below with reference to drawings and examples, the utility model is described in detail.
