Abstract
The utility model relates to a restoring device for the fracture and the dislocation of sacroiliac joints, which comprises movable arms, etc., wherein, the two movable arms are connected in the shape of a pair of scissors, and a pair of restoring claws is arranged on each movable arm. The two pairs of restoring claws are bended inwards to form an S shape in an opposite way, and the top ends of the restoring claws are bended inwards to form included angles of from 80 DEG to 90 DEG with claw bodies. The lower ends of the restoring claws of the two movable arms form included angles of from 130 DEG to 150 DEG with each other. Besides, the hinging position of the movable arms is provided with a toothed positioning block, and a regulating screw is arranged in the positioning block. The utility model can be convenient for the early operations of the fracture of sacroiliac joints; the long-time traction of limb bones and long-time restoration by outer fixing frames before operations are not needed; the restoring method is simple, and temporary fixation can be carried out after the restoration.
Description
This utility model relates to a kind of sacroiliac fracture-dislocation positor.
For serious unstable fracture of pelvis, improper as early time treatment, often can cause not isometric because of concurrent pair of lower limb of the instability of pelvis in late period, sacroiliac joint pain and following waist degeneration.Thereby new viewpoint has been arranged on the Therapeutic Principle of unstable fracture of pelvis in recent years, advocate early stage open reduction internal fixation.Thereby when treatment sacroiliac joint fracture was carried out internal fixation, necessary advanced horizontal reset just can carry out internal fixation.As not resetting preferably, then can't carry out internal fixation.Still there is not the development of this positor at present both at home and abroad.Traditional repositioning method is to carry out single lower limb or the traction of bilateral Lower limb bone or external fixer to reset before open reduction.The domestic and international external fixer of developing then can not reset to the dislocation that its sacroiliac joint makes progress at present, thereby can only adopt long-time bone reduction by traction, this method shortcoming that resets is: first, prolonged the time of open reduction internal fixation, reduction by traction does not often reach satisfied para-position, increase operating difficulty and amount of bleeding, prolonged patient's hospital stays, increased patient's financial burden; The second, prolonged traction is prone to long-term bed and the pulmonary, urinary system infection, calculus formation and the venous thrombosis that cause, comes off, and life danger can appear in severe patient.
The objective of the invention is to be convenient to the early operation of sacroiliac joint fracture, do not need before the art long-time bones of extremities traction and external fixer resets, repositioning method simple, can make temporary fixed sacroiliac fracture-dislocation positor after resetting in order to provide a kind of.
Purpose of the present invention can be implemented by following measure:
A kind of sacroiliac fracture-dislocation positor contains lever arm etc.; Two lever arms are the shears shape and connect, on each lever arm, be provided with a pair of position restoring claw, two pairs of position restoring claws all inwardly curve oblique S shape in opposite directions, and its top becomes 80 ° of-90 ° of angles to inflection with corpus unguis, and the lower end of the position restoring claw on two lever arms is in 130 °-150 ° angle; Hinge joint place at lever arm is connected with the zigzag locating piece in addition, is provided with adjustment screw at locating piece: be in 30 ° of-55 ° of angles between two position restoring claws on each lever arm.
The present invention has following advantage compared to existing technology:
1, this utility model is designed to lever arm according to the principle of the shape and structure of sacroiliac joint and biomechanics and becomes to cut the shape hinge joint, is provided with the position restoring claw that two tops inwardly curve 90 ° on each lever arm; Can be convenient to position restoring claw and thrust ilium ear cylindrarthrosis, make the convenience that resets, simple; Hinge joint place at lever arm is provided with the zigzag locating piece in addition, and be provided with adjustment screw within it, can be convenient to regulate the angular aperture between the position restoring claw, so that the requirement of the requirement of adaptation different model and clamping, distortion power, its chucking power can reach 40-50kg, and the rotation distortion power can reach 50-70Kg; And adjustment screw is tightened and can be located, make temporary held stationary after being convenient to reset.
2, this utility model can be convenient to the sacroiliac joint early operation, and does not need that long-time bones of extremities traction and external fixer reset before the art, thereby has shortened patient's hospital stays, can alleviate patient's misery and financial burden to greatest extent.
3, this utility model does not need prolonged traction, thereby has eliminated the many serious complication due to the long-time bed traction; And reset fully, postoperative function recovers.
Concrete structure of the present utility model is provided by the following drawings:

1-lever arm 2-adjustment screw 3-locating piece 4-position restoring claw
Fig. 2 is a right view of the present utility model
This utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1,2 embodiment are described in further detail:
With reference to Fig. 1,2, a kind of sacroiliac fracture-dislocation positor contains lever arm (1) etc.; Two lever arms are the shears shape and connect, on each lever arm (1), be provided with a pair of position restoring claw (4), two pairs of position restoring claws (4) all inwardly curve oblique S shape in opposite directions, its top becomes 80 ° of-90 ° of angles to inflection with corpus unguis, the lower end of the position restoring claw (4) on two lever arms (1) is in 130 °-150 ° angle; Hinge joint place at lever arm (1) is connected with zigzag locating piece (3) in addition, is provided with adjustment screw (2) in locating piece (3); Be in 30 ° of 55 ° of angles between two position restoring claws (4) on each lever arm (1).
Claims (2)
1, a kind of sacroiliac fracture-dislocation positor contains lever arm (1) etc.; It is characterized in that two lever arms (1) are the shears shape and connect, on each lever arm (1), be provided with a pair of position restoring claw (4), two pairs of position restoring claws (4) all inwardly curve oblique S shape in opposite directions, its top becomes 80 ° of-90 ° of angles to inflection with corpus unguis, the lower end of the position restoring claw (4) on two lever arms (1) is in 130 °-150 ° angle; Hinge joint place at lever arm (1) is connected with zigzag locating piece (3) in addition, is provided with adjustment screw (2) in locating piece (3).
