Abstract
Disclosed is an orthopaedics compression orientation drill bushing which belongs to the medical device technical field and comprises a crank arm, a straight arm, a turnbuckle, a guide head and a positioning joint; the crank arm is integrated with the straight arm to a whole; the bent end of the crank arm is provided with the positioning joint; the turnbuckle is arranged on the straight arm; the guide head is screwed in the turnbuckle; the guide head and the positioning joint are in the same axial line; the opposite surfaces of the guide head and the positioning joint are provided with strip patterns. when the orthopaedics compression orientation drill bushing is in use, the wounded limb of the patient is clamped between the straight arm and the crank arm; the position of the drill bushing is adjusted to enable the axial line of the guide head and the positioning joint to pass the bony mark; a bone circular needle is inserted into the backbone through the center circular hole of the guide head and is inserted into circular hole of the positioning joint through the limb. The orthopaedics compression orientation drill bushing has the advantages of simple structure, reliable performance and good safety.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of orthopaedics directed drill bushing that pressurizes.
Background technology
In the clinical medicine, extremity fracture is a common disease in the bone wound, and the bone traction is again the normal Therapeutic Method that adopts of treatment fracture, and concrete grammar is that requirement bone garden pin is laterally accurately punched the endoplasm layer, makes bone garden pin vertical with the key longitudinal axis.Also be difficult to once success even experienced orthopedist's manual operations is got up,, also can increase misery to the patient if once can not successfully not only influence the operation quality.Also all there are problems in various degree such as the fixing difficulty of operation, program complexity in the orthopaedics guider of now having announced.
Summary of the invention
The purpose of this utility model provides a kind of orthopaedics simple in structure, dependable performance directed drill bushing that pressurizes.
This utility model is achieved in that the orthopaedics directed drill bushing that pressurizes, include crank arm, straight-arm, swivel nut, guide head, landing nipple form.Crank arm and straight-arm is made one, the curved end of cranking arm is provided with a location joint, and straight-arm is provided with swivel nut, is provided with guide head in the swivel nut, and guide head is screwed in the swivel nut and can spinning in and out in swivel nut.
There is circular hole at the guide head center, and guide head and landing nipple are on same axis, and the opposite face of guide head and landing nipple is established decorative pattern respectively.
When using this utility model, between the limbs that the patient is injured are clipped in straight-arm and crank arm, thickness according to patient's limbs, adjust the utility model position, make guide head and landing nipple axis, correctly locate the position that spicule passes by bone mark, adjust the rotary steering head, make guide head and landing nipple clamp patient's injured limb, bone garden pin is squeezed into the backbone by the guide head center hole, passes in the circular hole that limbs enter orientation joint.Take off this utility model then, finish and squeeze into the pin operation of bone garden
This utility model is simple in structure, dependable performance, safety are good, has use value and market prospect preferably.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein: 1, crank arm 2, straight-arm 3, swivel nut 4, guide head 5, landing nipple
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further: as shown in the figure, the orthopaedics directed drill bushing that pressurizes includes and cranks arm 1, straight-arm 2, swivel nut 3, guide head 4, orientation joint 5 form.Crank arm 1 and straight-arm 2 make one, 1 the curved end of cranking arm is provided with landing nipple 4, straight-arm 2 is provided with swivel nut 3, guide head 4 is screwed in the swivel nut 3 and can spinning in and out in swivel nut 3.There is circular hole at guide head 4 centers, and guide head 4 and landing nipple 5 are on same axis, and the opposite face of guide head 4 and landing nipple 5 is established the bar shaped decorative pattern respectively.During use, the limbs that the patient is injured are clipped in straight-arm 2 and crank arm between 1, adjust the utility model position, make guide head 4 and landing nipple 5 axis pass through bone mark, the position that correct location spicule passes, adjust rotary steering head 4, make guide head 4 and landing nipple 5 clamp patient's injured limb, the decorative pattern on guide head 4 and landing nipple 5 surfaces can guarantee that this utility model can be from landing on the limbs, bone garden pin is squeezed into the backbone by guide head 4 center holes, pass in the circular hole that limbs enter landing nipple 5, guaranteed that osseous pin correct direction on request passes limbs.
