Description
Technical field
This utility model relates to the orthopaedics technical field of medical instruments, relates in particular to a kind of orthopaedics directed drill bushing that pressurizes.
Background technology
In the clinical medicine, extremity fracture is a disease common in the bone wound, and the bone traction is again the normal Therapeutic Method that adopts of treatment fracture, and concrete grammar is that the requirement osseous pin is laterally accurately punched the endoplasm layer, makes osseous 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 orthopaedics guider in the past.There is the people that existing orthopaedics guider is improved for this reason, as State Intellectual Property Office on January 21st, 2009 disclosed by Yang Jianjun design, the patent No. is 200820007450.3, name is called the pressurize utility model patent of directed drill bushing of orthopaedics, it by crank arm, straight-arm, swivel nut, guide head, landing nipple form, crank arm and straight-arm make one, the curved end of cranking arm is provided with a location joint, straight-arm is provided with swivel nut, be provided with guide head in the swivel nut, guide head is screwed in also can spinning in and out in swivel nut in the 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.During use, between the limbs that the patient is injured are clipped in straight-arm and crank arm, thickness according to patient's limbs, adjust the position of directed drill bushing, 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, osseous pin is squeezed into the backbone by the guide head center hole, passes in the circular hole that limbs enter orientation joint.Take off directed drill bushing then, finish and squeeze into osseous pin operation, have simple in structure, dependable performance, characteristics that safety is good.Its shortcoming is that guide head, landing nipple and patient's limbs contact area is little, and directed drill bushing need be dominated by hand always in the use, and operation inconvenience also can prolong operating time.
Summary of the invention
Thereby the purpose of this utility model provides a kind of orthopaedics of easy to operate shortening operating time directed drill bushing that pressurizes.
The technical scheme that this utility model is adopted for achieving the above object is:
A kind of orthopaedics directed drill bushing that pressurizes, comprise crank arm, straight-arm, swivel nut, guide head, landing nipple, crank arm and straight-arm make one, the curved end of cranking arm is provided with landing nipple, straight-arm is provided with swivel nut, be provided with guide head in the swivel nut, guide head is screwed in the swivel nut and can spinning in and out in swivel nut, the center of guide head and landing nipple is provided with circular hole, guide head and landing nipple is characterized in that on same axis: the end that described guide head end is connected with left location-plate, landing nipple is connected with right location-plate.
Use for convenience, described left location-plate is provided with chute, is provided with in the chute to have screw on the slide block along the slide block of chute slip, and guide head can be screwed in this screw.
Use for convenience, described right location-plate is provided with chute, and the end of landing nipple is provided with annular projection, and this annular projection can slide in chute.
Described left location-plate, right location-plate are provided with slotted hole, and the width of slotted hole is equal to or slightly greater than the diameter of the circular hole that the center of guide head and landing nipple is provided with.
The orthopaedics of the present utility model directed drill bushing that pressurizes, the end that is connected with left location-plate, landing nipple in the guide head end is connected with right location-plate, can conveniently locate for the patient of extremity fracture, shortens operating time; And should not use location-plate for other positions the time, also location-plate can be taken off.
