Description
Technical field: the operation equipment, particularly a kind of guider of artificial hip joint replacement acetabular reamer that the invention belongs to medical field.
Background technology: in the existing artificial hip joint replacing operation, the guide rod of reamer for hip arthroplasty,acetabulum enters acetabular bone and relies on the experience of implementing operative doctor to finish fully.Often because patient's the position of lying on one's side is nonstandard, affects the doctor and operate reamer for hip arthroplasty,acetabulum cut-in angle accuracy, so that deviation appears in artificial mortar position and angle, the rear artificial dislocation of hip joint of operation may occur further, cause operative failure.Use in addition at present the infrared rays navigation system abroad, 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, the equipment cost appropriate litigation fees is expensive; 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 occurs a bit to change, 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 guider of artificial hip joint replacement acetabular reamer, exist with the solution background technology: it is inadequate that the doctor operates reamer for hip arthroplasty,acetabulum cut-in angle accuracy, so that deviation appears in artificial mortar position and angle, the rear artificial dislocation of hip joint of operation may further occur, and causes operative failure.Solving this technical problem the technical scheme that adopts is: a kind of guider of artificial hip joint replacement acetabular reamer, an end that it is characterized in that the A cross bar connects the A vertical pole by the A sleeve with set screw, A vertical pole lower end connects the screw mandrel with handle, and the termination of screw mandrel arranges the rumpbone dop; The A cross bar connects the B cross bar by the B sleeve with set screw; The front end of B cross bar is by connecting the B vertical pole with the C sleeve of set screw, and the B vertical pole connects and turns up bar and shape in angle of 45 degrees, and the bar that turns up is with hinged rotatable with the bar bottom of leaning forward of protractor and gathering sill; The B vertical pole is connected on the A cross bar by the F sleeve with set screw; The other end of A cross bar connects the C vertical pole by the D sleeve with set screw, and right angle, C vertical pole bottom bends and pegs graft by set screw and the C cross bar with the pubic symphysis dop; C vertical pole bottom also connects the D vertical pole by the D cross bar, connects with the G sleeve with set screw on the E sleeve of set screw and the D vertical pole on the D cross bar; The E cross bar with the H sleeve connecting belt A anterior superior iliac spine dop of set screw is passed through in D vertical pole upper end, connecting belt B anterior superior iliac spine dop after the bending of right angle, D vertical pole lower end.Wherein, the A cross bar is to form the connection that relocates after rotatable by bearing pin by connect the B cross bar with the B sleeve of set screw.B cross bar and axis bar are pegged graft.
The beneficial effect that the present invention has compared with the prior art is: owing to adopt technique scheme, when needing operation, with the body sizes of this device according to the patient, adjusting device is so that the rumpbone dop, A, B anterior superior iliac spine dop, the pubic symphysis dop is in respectively relevant position and the locking of patient body, the B vertical pole is adjusted to patient's hip joint position, the B vertical pole connects the center that the bar institute shape of turning up is the acetabular bone physiological location of turning up in angle of 45 degrees just, rotate again and lean forward bar after protractor shows 15 degree, at this moment the residing space of gathering sill and angle are exactly accurate location, the doctor can fully guarantee the cut-in angle accuracy along the incision of gathering sill operation reamer for hip arthroplasty,acetabulum, so that artificial mortar position and angle zero deflection, effectively avoid occuring artificial hip joint operation backward dislocation, improve success rate of operation.When recurring structure is unusual after unusual for the acetabular development especially or pathological changes, more can show its superiority.Simultaneously, the present invention and infrared rays navigation systematic comparison, have low without iatrogenic injury, convenience simple to operation, cost, without the advantage of Postural restriction.
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.
The specific embodiment: with reference to figure 1, Fig. 2, a kind of guider of artificial hip joint replacement acetabular reamer, an end that it is characterized in that A cross bar 7 connects A vertical pole 8 by the A sleeve 6 with set screw, and A vertical pole 8 lower ends connect the screw mandrel 9 with handle 10, and the termination of screw mandrel 9 arranges rumpbone dop 11; A cross bar 7 connects B cross bar 2 by the B sleeve 3 with set screw; The front end of B cross bar 2 connects B vertical poles 4 by the C sleeve 13 with set screw, and B vertical pole 4 connects and turns up bar 26 and shape in angle of 45 degrees, and the bar 26 that turns up is with hinged rotatable with bar 25 bottoms of leaning forward of protractor 12 and gathering sill 14; B vertical pole 4 is connected on the A cross bar 7 by the F sleeve 5 with set screw; The other end of A cross bar 7 connects C vertical pole 23 by the D sleeve 24 with set screw, and right angle, C vertical pole 23 bottom bends and pegs graft by set screw and the C cross bar 21 with pubic symphysis dop 16; C vertical pole 23 bottoms also connect D vertical poles 20 by D cross bar 27, connect with the G sleeve 19 with set screw on the E sleeve 22 of set screw and the D vertical pole 20 on the D cross bar 27; The E cross bar 28 with the H sleeve 18 connecting belt A anterior superior iliac spine dops 15 of set screw is passed through in D vertical pole 20 upper ends, connecting belt B anterior superior iliac spine dop 17 after the bending of right angle, D vertical pole 20 lower end, it is the connections that relocate by after bearing pin 29 formation rotatably that A cross bar 7 connects B cross bar 2 by the B sleeve 3 with set screw, and B cross bar 2 is pegged graft with axis bar 1.
