Abstract
The invention belong to a positioning device for the bone-cutting angle and the anteversion angle of a femoral neck, which aims to solve the problems of surgical failures caused by dislocation of an artificial hip joint because an artificial femoral neck has position and angle differences and cannot be effectively matched with an artificial femoral head due to frequent operation inaccuracy of doctors existing in the prior art. The device is technically characterized in that: an upper vertical rod is inserted into a lower vertical rod through a positioning screw A; the bottom end of the lower vertical rod is hinged with a front vertical rod in a rotatable way; an angle gauge which is arranged on the lower vertical rod is used for measuring the rotation angle of the front vertical rod; the front vertical rod is hinged with a cross rod in the rotatable way; the cross rod is inserted into an anteverted rod through a positioning screw B; the tail end of the anteverted rod is connected witha left or right bone-cutting saw line guide frame; a chuck A is arranged on the upper vertical rod; a chuck B is arranged on the lower vertical rod; and the cross rod is connected with a chuck C through a positioning screw C. The device can be used for an artificial hip joint replacement surgery; and the invention has the outstanding advantages that: the device does not have the position and angle differences after the cutting of the femoral neck, is effectively matched with the artificial femoral head and improves the success rate of the surgery.
Description
Technical field: the operation equipment, particularly a kind of neck of femur osteotomy angle and top rake positioner that the invention belongs to medical field.
Background technology: in the existing artificial hip joint replacing operation, the osteotomy of neck of femur relies on range estimation and the experience of implementing operative doctor to operate cutting position and the space angle that osteotomy is sawed fully.Often because the doctor operates misalignment, make artificial femur neck position and angle deviation occur, can not effectively cooperate with artificial thigh bone, the artificial hip joint dislocation takes place, cause operative failure.Use the infrared rays navigation system at present abroad in addition, but the problem that exists is: the osseous tissue that one, many places are attacked in the human body is done sign, has not only especially increased iatrogenic injury, and may cause infection suppurates, causes the failure of performing the operation; Its two, complex operation is wasted time and energy during use, generally all wants a moment many clocks to operate; Its three, equipment cost appropriate litigation fees costliness; Its four, operating technology skillfully to need to require Special Training; Its five, blind spot is more in the operating process, position is restricted; Its six, participate in the surgical staff occupy-place and be restricted, have influence on the normal operating of operation, its seven, equipment separates with human body, human body is very unstable, as long as patient's health origination point changes, the accuracy of infrared rays navigation system lost efficacy immediately.
Summary of the invention: purpose of the present invention is exactly the technical scheme that proposes a kind of neck of femur osteotomy angle and top rake positioner, exist with the solution background technology: often because the doctor operates misalignment, make artificial femur neck position and angle deviation occur, can not effectively cooperate with artificial thigh bone, the dislocation of generation artificial hip joint causes operative failure.Solving this technical problem the technical scheme that adopts is: a kind of neck of femur osteotomy angle and top rake positioner, it is characterized in that montant is plugged in down in the montant by the A set screw, following montant bottom and preceding montant are hinged rotatable, the protractor that arranges on the following montant is with the rotational angle of montant before measuring, preceding montant and cross bar are hinged rotatable, cross bar is by the B set screw bar that leans forward of pegging graft, a terminal left side or the right osteotomy saw swage set leading truck of connecting of the bar that leans forward, the A dop is set on the last montant, following montant arranges the B dop, and cross bar connects the C dop by the C set screw.Wherein, lean forward that bar is terminal to connect a left side or right osteotomy saw swage set leading truck is replaced as the femoral myelocavity file guide post.
The beneficial effect that the present invention has compared with the prior art is: owing to adopt technique scheme, when needing operation, A dop, the B dop of this device are stuck in patient's posterior calf, the C dop is stuck in patient's back of thighs, rotate about L shaped bar 15 degree according to the data of protractor angle indication, this moment, the osteotomy saw residing position of swage set leading truck and angle were exactly the accurate position of implementing the neck of femur osteotomy, saw blade is inserted the cutting of osteotomy saw swage set leading truck get final product.Osteotomy swage set leading truck is replaced as the femoral myelocavity file guide post, rotates about L shaped bar 15 degree according to the data of protractor angle indication equally, this moment, the residing position of femoral myelocavity file guide post and angle were exactly the accurate position of incision femoral myelocavity file.Rely on accurately location of this device like this, make neck of femur cutting position, back and angle zero deflection to form effective the cooperation with artificial thigh bone, avoided the artificial hip joint dislocation, improve success rate of operation.Simultaneously, the present invention and infrared rays navigation systematic comparison have no iatrogenic injury, convenience simple to operation, low, the no position restriction of cost.
Description of drawings: Fig. 1 is overall structure sketch map of the present invention.Fig. 2 is that the A of Fig. 1 is to partial view.Fig. 3 is the design of part figure of femoral myelocavity file guide post among the present invention.
The specific embodiment: with reference to figure 1, Fig. 2, Fig. 3, a kind of neck of femur osteotomy angle and top rake positioner, it is characterized in that montant 1 is plugged in down in the montant 10 by A set screw 11, following montant 10 bottoms and preceding montant 3 are hinged rotatable, the protractor 2 that arranges on the following montant 10 is with the rotational angle of montant 3 before measuring, preceding montant 3 is hinged rotatable with cross bar 14, cross bar 14 is by B set screw 4 bar 5 that leans forward of pegging graft, bar 5 a terminal left side or the right osteotomy saw swage set leading trucks 6 of connecting lean forward, on the last montant 1 A dop 12 is set, following montant 9 arranges B dop 9, and cross bar 14 connects C dop 7 by C set screw 8.Bar 5 terminal connection left sides or the right osteotomy of leaning forward sawed swage set leading truck 6 and is replaced as femoral myelocavity file guide post 13.
