Description
One, technical field:
This utility model relates to medical apparatus and instruments, especially knee joint peripheral osteotomy guider.
Two, background technology:
The knee joint peripheral osteotomy is the treatment knee joint osseous arthritis and corrects deformity of knee operation method commonly used, whether osteotomy position and angle accurately directly influence the postoperative curative effect, traditional osteotomy localizer is subjected to the influence of osteotomy position skeleton width, when osteotomy bony segment width increases, cut wedge bone piece tip by guider and can not reach offside, when osteotomy position skeleton width reduced, horizontal osteotomy and oblique osteotomy surface can not intersect at the offside sclerotin, can too much remove the offside sclerotin.Do rough estimate as correcting 1 degree deformity,, can cause this method manifest error to occur when osteotomy base camber changes or iconography amplifies when bringing error according to 1 millimeter.Should be taken into account the developed width of institute's osteotomy bone when using said method, otherwise can cause the osteotomy deficiency.
Three, summary of the invention:
The purpose of this utility model provides a kind of easy and simple to handle, the knee joint peripheral osteotomy guider of accurate positioning, it has solved the deficiency of present technology, the purpose of this utility model is to realize like this, it is to be formed by connecting by sleeve, angle positioning disk, horizontally-guided bar, location slide plate, guide pin, pilot hole, lock nut, handle, guide pinhole and kerf, the horizontally-guided bar takes the shape of the letter U, and an end and angle positioning disk are connected to become an integral frame, and its other end is sharp keen sharp cone distal; Each arm of horizontally-guided bar all is 90 degree, and angle positioning disk side indicates scale, is straight shape arm more than 0 degree, is 2 centimetres highly, is divided into 10 down scales, and each down scale length is 2 millimeters; Below 0 degree is arched arm, and 6 big lattice are arranged, and 30 little lattice, each little lattice are 1 degree, and each big lattice is 5 degree, and angle positioning disk end is 30 degree; One location slide plate is arranged on the angle positioning disk, have a slideway, angle positioning disk to pass the slideway of location slide plate in the middle of the slide plate of location, the location slide plate can be free to slide both contact surface indentations on positioning disk; Lateral surface at the location slide plate has a lock nut, screws lock nut the location slide plate is firmly fixed on the angle positioning disk; At angle positioning disk 0 degree place and diameter is all arranged on the slide plate is 6 millimeters pilot hole in the location; It is cylindric that sleeve is, and external diameter is 6 millimeters, and internal diameter is 3 millimeters, and sleeve one side end face is spiculation, and opposite side has the hands handle; The guide pin diameter is 3 millimeters, adapts with sleeve diameter, and its length has multiple model; The osteotomy guide plate is rectangular shape, two holes are arranged below it, be used to penetrate guide pin, there is the osteotomy kerf top in hole, be used to insert goose saw, the center in two holes and the distance of kerf equal to locate pilot hole center and the distance of locating the slide plate upper limb on the slide plate, and the actual angle of osteotomy is the scale value of location slide plate upper limb correspondence on the angle positioning disk.
During use, the interior outside of inserting the tibial plateau upper limbs with two pieces of injection needles is closed pitch plane to intraarticular with sign, and the tip of horizontally-guided bar is placed the inboard joint of tibial plateau lower edge 1.5 or 2 centimeters, and is concordant because of outside articular surface on the angle positioning disk; Dispose sleeve in 0 degree, penetrate horizontal guide pin; By the extremely corresponding angle of the osteotomy angle running fix slide plate of measuring before the operation, screw lock nut, sleeve is inserted the pilot hole of location slide plate, penetrate oblique guide pin, place to go guide post and positioning disk, the osteotomy guide plate is placed on the guide pin, and goose saw inserts the kerf of osteotomy guide plate, capable respectively horizontal osteotomy and oblique osteotomy.
The utlity model has easy and simple to handlely, accurate positioning reduces that x line perspective is not subjected to the advantages such as influence of skeleton width to the infringement of human body in the operation.
