Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
Consult shown in Fig. 1, the apparatus structure schematic diagram continuing drawing-off for lower limb for the embodiment of the present invention is a kind of, the described device continuing drawing-off for lower limb comprises base 1, track 2, first fixing head 3, second fixing head 4, the 3rd fixing head 5, first fixing band 6, second fixing band 7, the 3rd fixing band 8, first connecting axle 9, second connecting axle 10, first transfer arm and the second transfer arm.Wherein, described track 2 is arranged on this base 1.Further, one end of the first fixing head 3 is connected to an end of this base 1, and the other end of the first fixing head 3 is connected with the second fixing head 4 by the first connecting axle 9, and the other end of the second fixing head 4 is connected with the 3rd fixing head 5 by the second connecting axle 10.Preferably, one end of the first fixing head 3 and one end of the second fixing head 4 are socketed on the first connecting axle 9 simultaneously.Preferably, the other end of the second fixing head 4 and one end of the 3rd fixing head 5 are socketed on the second connecting axle 10 simultaneously.
Further, the first fixing band 6 is arranged on described first fixing head 3, and the second fixing band 7 is arranged on described first fixing head 3, and the 3rd fixing band 8 is arranged on the 3rd fixing head 5.Preferably, the first fixing band 6, second fixing band 7, the 3rd fixing band 8 are arranged on the position placed in the middle of the first fixing head 3, second fixing head 4, the 3rd fixing head 5 respectively.
In addition, one end of the first described transfer arm is fixedly connected on the junction of the first fixing head 3 and the second fixing head 4, and the other end of described first transfer arm is socketed on track 2.One end of described second transfer arm is fixedly connected on the junction of the second fixing head 4 and the 3rd fixing head 5, and the other end of described second transfer arm is socketed on track 2.
Therefore, described when continuing the device busy of drawing-off for lower limb, lower limb can fix through the first fixing band 6, second fixing band 7, the 3rd fixing band 8 and the first fixing head 3, second fixing head 4, the 3rd fixing head 5 by patient successively.That is, the thigh of patient can be fixed on the first fixing head 3, and shank can be fixed on the second fixing head 4, and foot can be fixed on the 3rd fixing head 5.Then, due to the first transfer arm on track 2 and the second transfer arm, make patient's lower limb can carry out drawing-off constantly on track 2.
In one embodiment of the invention, the junction of described first transfer arm and track 2 is provided with fixing button, and the junction of described second transfer arm and track 2 is provided with fixing button.When described first transfer arm, the second transfer arm move to a certain position on track 2, position can be fixed respectively by described fixing button.
In another embodiment of the present invention, the described device continuing drawing-off for lower limb also comprises power supply (not indicating in Fig. 1) and controller 15.Wherein, power supply and controller 15 are all arranged on described base, and power supply is connected with controller 15.And controller 15 can be electrically connected with the first transfer arm, the second transfer arm respectively.Therefore, can realize automatically controlling the first transfer arm, the slip of the second transfer arm on described track 2 by controller 15, thus the lower limb that can control patient carry out stretch exercise constantly.
As one embodiment of the present of invention, described first transfer arm comprises the first flexible upper boom 11 and the first flexible lower beam 12.Wherein, one end of the described first flexible upper boom 11 is arranged on the junction of the first fixing head 3 and the second fixing head 4, and the other end is inserted in the described first flexible lower beam 12.And the other end of the first flexible lower beam 12 is arranged on track 2.It should be noted that, the inwall of the first flexible lower beam 12 is provided with slideway, first flexible upper boom 11 is inserted in the described first flexible lower beam 12, and the first flexible upper boom 11 can slide in the first flexible lower beam 12, thus achieves the length change of whole first transfer arm.
As an alternative embodiment of the invention, described second transfer arm can comprise the second flexible upper boom 13 and the second flexible lower beam 14.Wherein, one end of the described second flexible upper boom 13 is arranged on the junction of the first fixing head 3 and the second fixing head 4, and the other end is inserted in the described second flexible lower beam 14.And the other end of the second flexible lower beam 14 is arranged on track 2.It should be noted that, the inwall of the second flexible lower beam 14 is provided with slideway, second flexible upper boom 13 is inserted in the described second flexible lower beam 14, and the second flexible upper boom 13 can slide in the second flexible lower beam 14, thus achieves the length change of whole second transfer arm.Therefore, the described device continuing drawing-off for lower limb can make the lower limb of patient perpendicular to the stretch exercise direction of level also obtaining continue.
Preferably, described first fixing band 6, second fixing band 7, the 3rd fixing band 8 adopts respectively has elastic elastomeric material.Thus, more securely patient's lower limb can be tied on three described fixing heads, also can not produce uncomfortable sensation.
This shows, the device continuing drawing-off for lower limb that the present invention proposes, creatively by track installation on base, and one end of the first fixing head is connected to an end of base, the other end of the first fixing head is connected with the second fixing head the 3rd fixing head successively by the first connecting axle, the second connecting axle; One end of first transfer arm is fixedly connected on the junction of the first fixing head and the second fixing head, and the socket of the other end of the first transfer arm in orbit; One end of second transfer arm is fixedly connected on the junction of the second fixing head and the 3rd fixing head, and the socket of the other end of the second transfer arm in orbit; Thus achieving patient's lower limb can carry out drawing-off constantly in horizontal rail; Which solve the problem that existing therapeutic device does not continue electronic drawing-off, lower extremity motor function obstacle is served to the effect for the treatment of; In addition, the first transfer arm and the second transfer arm can realize upper and lower flexible, thus achieve the device continuing drawing-off for lower limb of the present invention perpendicular to the stretch exercise in horizontal direction, and therefore its therapeutic effect is more remarkable; And this is used for lower limb, and to continue the device of drawing-off practical, comparatively can drive fixing head motion by good utilisation transfer arm, improve joint of the lower extremity motor function; Meanwhile, proposition to continue the equipment safety of drawing-off for lower limb reliable, simple to operate; Finally, whole described to continue the device of drawing-off for lower limb accurate, easy, is easy to operation.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
