Abstract
The utility model provides a guiding device of a bone needle. The utility model is characterized in that one end of the 'U'-shaped guide body is provided with a changeable guiding head, and the other end of the 'U'-shaped guide body is provided with a clamping bar; a chuck is fixed in the inner end of the clamping bar; the chuck and the guiding head share a center line; according to the principle of two points forming a line, the round bone needle can be driven into the backbone accurately without declination. The utility model has the advantages that the successful rate is 100%, and the pain of patients is reduced. The utility model is used by orthopedists, in particular to the young orthopedists.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly bone garden pin guider.
Extremity fracture is one of common disease of bone wound, and the bone traction is the normal method that adopts of treatment fracture, executes the method, requires the sagittal plane of bone garden pin before and after bone, and is vertical with the key longitudinal axis.Reach this requirement clinically, even experienced old orthopedist the operation on once success rate also be very low.As squeezing into bone garden pin repeatedly, can increase misery to the patient, be bigbore as the bone garden pin that uses, in addition long diaphysis is played the danger of splitting.Thereby cause the failure for the treatment of.
The purpose of this utility model provides a kind of bone garden pin guider, to improve success rate.
The purpose of this utility model is that the design according to following accompanying drawing realizes.
Fig. 1 is a structural representation of the present utility model.
On an end of U-shaped guide way 1, swivel nut 2 is arranged, interchangeable guide head 3 is screwed in the swivel nut.On the other end of U-shaped guide way, one fixing sliding sleeve 7 is arranged, clamping bar 6 is inserted in the sliding sleeve, inner end at clamping bar, fix a chuck 5 with screw 4, by bone mark, determine the position that bone garden pin passes before the shared centrage of chuck and interchangeable guide head, art, this utility model is stuck in the site of disease of arm or lower limb, by adjusting clamping bar, clamp arm or lower limb after, with steady pin 8 clamping bar is fixed, in order to prevent that clamping bar from rotating, can reserve the groove 9 of a spill on clamping bar, steady pin enters in the groove 9, with the centrage that guarantees chuck and clamping bar on a line.After this utility model is clamped arm or lower limb, also can twist interchangeable guide head, finely tune, to reach not only comfortable, but also firm purpose.Bone garden pin is squeezed into the backbone by interchangeable guide head, passes limbs, enters in the collet bore, takes off this utility model again.
The utility model is compared with prior art squeezed into key success rate and can near 100%, be reduced patient's misery.
