Description
Technical field
This utility model belongs to the rehabilitation medical utensil, particularly a kind of medical apparatus of human body knee joint rehabilitation.
Background technology
Knee osteoarthritis claims degeneration gonarthritis, morphotropism gonarthritis again.This sick incidence rate rises with the growth at age, particularly arrives person in middle and old age's phase, and prevalence obviously raises.The patient mainly shows as arthralgia, strand lock, dysfunction.Medicine, nerve block therapy, operative treatment and simple physics factor in treatment are adopted in the treatment of knee osteoarthritis at present more, but effect is all unsatisfactory.Joint Mobilization is the clinical symptoms of reduction of patient well, be a kind of safe, effective, painless treatment technology, but free-hand operation not only is difficult to guarantee therapeutic effect, and can increases medical workers.
Chinese patent ZL200620035234.0 discloses a kind of knee joint rehabilitation extension table, this extension table comprises bedstead, place the bed board on the bedstead, be contained at least one group of slide rail on the bedstead rear portion along the bedstead length direction, cooperate with slide rail can along slide rail slide and can be fixed before, back hinged bearing, before the thigh frame that a end in the lower limb bearing support is mutually hinged and the other end of shank frame are hinged on respectively, on the back hinged bearing, the thigh frame, the shank frame is respectively by sleeve pipe, one end stretches into the expansion link in the sleeve pipe and passes sleeve pipe one end and expansion link and the fixed set lever of sleeve pipe can be formed, by set lever its collapsing length is locked, the thigh backing plate is fixed on the thigh frame, the shank backing plate is connected on the shank frame by the sliding sleeve cover, along the direction of frame slidably, the thigh frame, the angle of shank frame can be adjusted in 30～180 degree scopes, has the gravity traction device that is connected with the shank frame (to comprise preceding fixed pulley in the extension table, back fixed pulley and counterweight).Though this kind extension table can be used for Joint Mobilization, the knee joint patient is implemented the gravity traction that difference is bent and stretched angle, structure is comparatively complicated, and volume is bigger, certainly will increase cost of manufacture and placement space, and is not easy to carry.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of knee joint major axis traction apparatus is provided, and this kind traction apparatus can not only satisfy the needs of knee joint being implemented the mobilization treatment, and structure is more simple, volume reduces, and is convenient to move and carry.
Knee joint major axis traction apparatus described in the utility model comprises base plate, thigh backing plate, shank backing plate, fixed pulley and counterweight; Offer the bar shaped rope through on the described base plate,, three groups of align members are installed at least on the base plate along bar shaped rope through long axis direction; One end of thigh backing plate and base plate are hinged, and its other end and shank backing plate are hinged, and the free end of shank backing plate is by one group of align member location in the align member; Fixed pulley is installed in the free end of shank backing plate, and stay cord one end that is wrapped on the fixed pulley is used to connect traction belt, and its other end passes the bar shaped rope through of offering on the base plate and is connected with counterweight.
According to clinical experience, it is that patient's knee joint is implemented mobilization treatment angle commonly used that the angle α between thigh backing plate and the shank backing plate is 90 °, 135 °, 165 °, 180 °, so three groups of align members should be installed on the base plate at least.If three groups of align members are installed on the base plate, when the free end of shank backing plate is located by first group of align member, angle α between thigh backing plate and the shank backing plate is 90 °, when the free end of shank backing plate is located by second group of align member, angle α between thigh backing plate and the shank backing plate is 135 °, when the free end of shank backing plate is located by the 3rd group of align member, angle α between thigh backing plate and the shank backing plate is 165 °, promptly three groups of align members should be able to satisfy the angle requirement between thigh backing plate and the shank backing plate in the installation site on the base plate, when thigh backing plate and shank backing plate lie on the base plate, then the angle α between thigh backing plate and the shank backing plate is 180 °.
The length L 2 of thigh backing plate, the length L 1 of shank backing plate can be designed to several sizes, to be adapted to the patient of differing heights.
Knee joint major axis traction apparatus described in the utility model is compared with the ZL200620035234.0 patent, designs simplification, and volume reduces, and cost reduces, and is convenient to move and carry.
