Abstract
The utility model relates to an orthopaedics device, which is mainly composed of a hip positive-negative screw device (4) and screw thread adjustment stems (3). Two claw hooks (5) which can seize an ilium are arranged on the hip positive-negative reverberation device (4), a rotation type connection device (6) is used for adjusting angles, and one knee half ring (1) fixed by an adjusting nut (8) is connected between the other ends of the screw thread adjustment stems (3). and a needle fixture is arranged on the knee half ring (1). The utility model has simple structure, the utility model can be randomly adjusted according to need, and a patient can earlier ambulates. The utility model is also characterized in simple operation, small damage to the patient, and good effect, and the utility model can treat the fracture of a femur and the ilium.
Description
This utility model belongs to a kind of orthopaedics medical apparatus and instruments.
Chinese patent CN2100873U discloses a kind of quick elastic joint traction and fixation multi-function frame, this device is only effective to traction and fixation, the energy early ambulation, but big radian adjusting does not reach requirement to the hip joint all directions, so displacement fracture is not reached the fixed purpose that resets.Penetrate the pin also more (totally 4 pieces) of skeleton, damage the specification requirement height that relatively large hip is had an injection, the general doctor is difficult for grasping.Fracture of pelvis there is not therapeutical effect.
The purpose of this utility model is to provide a kind of pull strength big, can reach ideal position, but patient's out-of-bed activity can arbitrarily be adjusted the direction and the angle of hip joint according to the needs of the state of an illness, threads a needle and has only one piece, damages little.In addition, hip is not threaded a needle, and is simple to operate, all exercisable holder of general doctor.
Summary of the invention of the present utility model is such, and the positive and negative spiral organ of Corti of a cover hip is arranged, and at the two ends of the positive and negative spiral organ of Corti of hip claw hook is installed, and during use claw hook is fixed on the preceding outer upper limb of two iliums.The positive and negative spiral organ of Corti of hip is screwed, can fixedly secure.Otherwise can unclamp.Outside the positive and negative spiral organ of Corti of hip, be with two rotating connectors, a threaded adjusting bar respectively is installed respectively on each rotating connectors and, regulates direction and angle with the needs that adapt to the hip state of an illness by rotation and the braking arbitrarily of rotating connectors double thread adjusting rod.The threaded adjusting bar other end links to each other with the knee joint semi-ring.The knee joint semi-ring is by the length in the adjusting nut scalable threaded adjusting bar fixed range.Two fixedly 2-2.5mm pin clip slot and pin folder spiral shell hook nuts are arranged on the knee joint semi-ring, and the two ends with Kirschner wire that can be nimble are fixed on the corresponding knee joint semi-ring.A complete set of holder can be connected to become a firm integral body.If need to prolong, shorten or regulate direction etc., the nut that only needs to regulate threaded adjusting bar lower end can reach.In addition, singly being fixed in two iliums with the positive and negative spiral organ of Corti of hip can treat fracture of pelvis.
Effect of the present utility model is such, by using this device, but patient's strap retainer early ambulation, and can regulate length, dynamics by screw thread, and arbitrarily adjust the direction and the angle of hip joint according to the needs of the state of an illness.Only wear one piece of pin, and hip do not thread a needle, little to patient trauma, simple to operate, the general doctor just can operate holder.Can be effectively hip and femur damage and disease be treated, particularly to the treatment of the fracture patient of can not tolerate surgery or being unwilling to perform the operation.And can reduce the generation of complication, make the disease early recovery.
Accompanying drawing is a structural representation of the present utility model.
Below be this utility model embodiment in conjunction with the accompanying drawings.
The multi-functional external fixator of the hip of present embodiment, by a cover positive and negative spiral organ of Corti of hip (4), two threaded adjusting bars (3) are formed, be separately installed with a claw hook (5) that can be fixed on upper limb outside two iliums preceding at the two ends of the positive and negative spiral organ of Corti of hip (4), connecting portion at positive and negative spiral organ of Corti of hip (4) and threaded adjusting bar (3), but double thread connecting rod (3) is installed arbitrarily to rotate and arresting rotating connectors (6), between the other end of two threaded adjusting bars (3), connect one by the fixed knee joint semi-ring of adjusting nut (8) (1), fixedly the pin clip slot (2) and the pin folder spiral shell hook nut (7) of 2-2.5mm pin are installed on knee joint semi-ring (1).The knee joint semi-ring is by adjusting nut (8) scalable threaded adjusting bar fixed range length.
