In order accurately to observe and the control pressure, a pull pressure sensor and read table thereof can be set on traction machine.
Above-mentioned support body turns to syndeton to can be universal joint, also can be following structure: the lower end of support body is stretched axle by a song and is linked to each other with last swivel base, between last swivel base and following swivel base rotational structure is arranged, and following swivel base can be fixedly mounted on the seat.Also can be only can do 360 ° of revolutions or only in the structure of 180 ° of rotations of sagittal plane.
Above-mentioned positor is mainly finished resetting of the forward and backward dislocation of traumatic hip joint, can make traditional dislocation of hip joint Allis manual reduction into mechanical return, and reaches and reset to the power height, the good result that need not anaesthetize.In order to finish resetting of hip joint central dislocation, fracture of femoral neck, intertrochanteric fracture and femoral shaft, fracture of tibia and fibula, can add attached seat on the basis of the above, attached seat links to each other with end seat, and attached seat is provided with the traction machine mounting structure.Traction engine is installed on the sliding panel of attached seat, end seat is provided with and ends rod.
Above-mentioned supporting plate can be fixing foot supporting plate or shank support plate.
Can be between attached seat and end seat and fixedly connected, is that roll adjustment is convenient, and available therebetween telescopic rail connects.
For easy to operate, can on attached seat, increase a sliding panel, rail plate is arranged therebetween, glide direction is vertical with the telescopic rail direction.
For easy to operate, can on attached seat, increase a sliding panel, rail plate is arranged therebetween, glide direction is vertical with the telescopic rail direction, and sliding panel is provided with the traction machine mounting structure.
Thread a needle in this positor two ends that need not to fracture, during the reduction of the fracture power near-end application point at pelvis, far-end application point at foot.The application point of this power has just determined to be applicable near the reduction of the fracture the reduction of the fracture of full lower limb, particularly hip joint.For example: dislocation of hip joint, fracture of femoral neck, intertrochanteric fracture etc.Before the more suitable Rhizoma Atractylodis Macrocephalae, reset in the art.Can reduction joint dislocation, particularly dislocation of hip joint, the reduction fracture is arranged again, need not anaesthetize, function is many, and reduction success rate height can be up to 100%.
Below in conjunction with embodiment and accompanying drawing this utility model is further described, but not as to qualification of the present utility model.
Fig. 1 is the structural representation of an embodiment.
Fig. 2 is the A-A cutaway view (when traction engine is upright) among Fig. 1.
Fig. 3 is the top view of sufficient supporting plate.
Among Fig. 1, Fig. 2, Fig. 3, be fixed with on the end seat 1 and end rod 2, and be provided with 3 liang of covers of traction engine installing hole, telescopic rail 4 is fixed on the attached seat 5, and the guide rail 18 below end seat 1 is slidingly matched, and attached seat 5 and sliding panel 6 cooperate, and rail plate is arranged therebetween, sliding panel 6 is provided with traction engine mounting structure 7,2 covers.The structure of traction engine is: be provided with worm and gear 16,17 in the support body 10, worm screw 17 is fixed on the support body 10 by axle, bearing block, and by the axle link to each other with hand crank 11, worm gear 16 is provided with screwed hole and leading screw 15 cooperates, leading screw 15 links to each other with supporting plate 13 by universal joint 12, and support body 10 lower ends are connected on the swivel base 19 by rotating shaft 9, between last swivel base 19 and the following swivel base 8 roller or ball are arranged, constitute 360 ° of rotary turnplate, guide rail 18 is fixed on the end seat 1.14 are the fixing supporting plate of foot that fixed structure 20 arranged.When needing, replaceable is shank support plate.Traction engine can be contained on the installation site on end seat or the attached seat as required.
Treatment hip joint traumatic dislocation: clockwise direction shakes hand crank can make the spiral strut give birth to (strutting), counterclockwise shaking hand crank can make screw fixed on base plate, its fixed position can be by patient's fracture dislocation side not and move left and right, can be on 360 ° of rotations of horizontal plane and sagittal plane between main frame and main frame 180 ° rotation, guarantee behind the main frame fixed base plate rotation that can be in any direction and bend and stretch movable any angle that needs.Being connected between main frame and shank support plate is that universal drive shaft connects, any angle of required rotation in guaranteeing to reset.When the forward and backward dislocation deeply concerned of traumatic hip resets, patient lies on the back on the base plate, with band nylon buckles wide strap fixedly trunk, hip on base plate, the 90 ° of positions of going down on one's knees, patient's shank is placed on the shank support plate, fixedly shank is on supporting plate with band nylon buckles wide strap, and assistant's clockwise direction shakes the main frame handgrip, the spiral strut rises, pull pressure sensor indication pulling force.The patient keeps the patient to go out knee joint each 90 ° of position of hip in the wrong and makes receipts and interior outward turning activity in the hip joint, with Allis dislocation of hip joint reduced method, take and hear snap when pulling force reaches institute, the joint promptly resets, and stops tractive, removes each and fixes, movable lower limb embolia as usual, during the reduction anterior dislocation of hip joint, will suffer from the traction of limb abduction external rotatory position, soon reset in interior then the receipts.
The dislocation of treatment hip joint centre type; fracture of femoral neck; before the intertrochanteric fracture art; reset in the art; fracture of shaft of femur; when fracture of tibia and fibula resets the positor base plate is linked to each other with the traction attached frame by telescopic connecting rod; with traction engine be fixed on the traction attached frame can the inside and outside slide plate that slides on; patient lies on the back on the base plate; lower limb stretch 180 °; height according to patient is adjusted the telescopic rail length of connecting rod; patient lies on the back on base plate; two lower limb stretch the position; when the spiral strut maximum elongation of traction engine, be fixed on patient's parapodum portion on the sufficient fixing head with binder; inserting anti-patient in bottom plate hole moves down rod (patient lies on the back and ends rod patient when the hip middle part prevents to lead the trouble limb down and move down; do countertraction); the universal drive shaft structure can make the trouble limb rotatablely move from all directions on demand because sufficient fixing head links to each other with main frame; because on can inside and outside sliding panel after main frame is fixing; can make the trouble limb do the interior abduction exercise of receiving, the various direction requirements in guaranteeing to reset.Counterclockwise rotate the main frame handgrip, after the main frame strut is done retracting motion, pulling force sensor indication pulling force in traction by the requirement that resets do receipts, the exhibition of suffering from the limb far-end, bend, stretch and rotatablely move reach reset the locking braking of satisfied back again the row operation fixing or on external fixer or plaster fixation etc., finishing recession and removing positor.Pull pressure sensor indication pulling force guarantees handling safety.
