Detailed description of the invention
Power controllable cervical vertebrae curve traction device, as shown in Figure 1, comprise seat 1, traction headgear 2, draft arm and the column 3 with the chair back, column 3 is vertically fixed on the chair back of seat 1.Wherein, draft arm is connected and composed by end by obtuse-angulate first arm of force 4 and second arm of force 5 mutually, and the middle part of first arm of force 4 is hinged on column 3, and one end that first arm of force 4 stretches to seat 1 front is connected with traction headgear 2 by traction steel wire 6; Second arm of force 5 is positioned at seat 1 rear, and the both sides of its end are equipped with cable 7, and the cable 7 of both sides is interconnected to constitute the control power apparatus of closed loop by the fall line fixed pulley mechanism 8 that seat 1 both sides are arranged.During use, the cable 7 in this control power apparatus is enclosed within human body sole, cable 7 can be realized pulls draft arm to rotate around the pin joint of itself and column 3 by bending and stretching human leg, namely when human body stretching leg, realize cervical traction operation; During bending human leg, realize the release of pull strength.This control power apparatus can realize the control of pull strength according to the degree of bending and stretching of patient self leg, use and easy to operate.
Traction headgear 2 as shown in Figure 2, comprise horizontal pressure pin 20, be connected to neck that the neck at horizontal pressure pin 20 two ends chin traction belt 21 and adding is located in the middle part of neck chin traction belt 21 after fixing band 22, neck chin traction belt 21 is connected by frenulum 9 with the lower end of fixing band after neck 22.Wherein, one end of frenulum 9 is fixed on the side of neck chin traction belt 21 lower end, and the offside of neck chin traction belt 21 lower end is provided with strap loop 11, is fixedly connected with after the frenulum perforation 10 after frenulum 9 passes neck, fixing band 22 arranged with strap loop 11 slip-knot.
Further, as shown in Figure 3, first arm of force 4 is hinged with the sliding sleeve 12 be set on column 3, and the periphery of sliding sleeve 12 is provided with the holding screw 13 for holding out against first arm of force 4.
Further, traction steel wire 6 is as shown in Figure 4 provided with steel wire snap close 14, and steel wire snap close 14 makes the closed loop suspension hook of end formation for fixed traction headgear 2 of traction steel wire 6.
This traction apparatus adopts the band shape traction headgear adapting to organization of human body, makes patient's completed treatment process under comfortable state.Ingenious utilization human leg bends and stretches power and provides power for traction, saves space and cost.Patient can directly be sitting on seat 1, whole body is in relaxation state, along with the increase of human leg's level of stretch, cervical vertebra does static traction by pulling and extension with shoulder breast trunk, patient can control the level of stretch of its leg according to the state of an illness, control the size of pull strength according to self sensation, avoid the injury unnecessary to patient caused because pull strength is out of control.Simultaneously because the control of power is completed by patient oneself, eliminate patient because of the improper pain that causes and the fear at heart of exerting a force, make therapeutic effect more obvious.The most important thing is, the movement locus of the first arm of force 4 traction end is circular arc line, compared with prior art, the traction stress strain curve of cervical vertebra can be matched with the biological camber line of human cervical spine, avoid prior art cathetus to draw the defect damaged cervical vertebra.In order to determine the use curative effect of this traction apparatus further, the model machine of this traction apparatus is tried out at hospital clinical, follow up survey 50 routine patients use the situation analysis of this traction apparatus: before use, cervical spondylosis is diagnosed as according to medical verification, after using, after 30 to 45 days treatment cycle, there is obvious curative effects 41 example, sensation alleviates 5 examples to some extent, and aggregate efficiency reaches 92%.Prove that this traction apparatus has help clearly to cervical vertebrae recovery therapeutic process.
