Abstract
The invention discloses a kind of waists to adjust draft gear manually, it includes waist fixing device, manual rackwork, counter weight device, supporting surface, leash；The present invention has abandoned the principle that common traction equipment makees tractive force using material forces, it uses the gravity of counter weight device to make tractive force and the angle of inclination by the gravity of counter weight device by adjusting supporting surface is combined with supporting surface, manual rackwork, reach gravity, tractive force, support force three balance, 0 tractive force can be arbitrarily adjusted between counter weight device gravity, there is better controllability and durability compared to existing similar medical equipment, and patient's change body position will not change tractive force.
Description
Technical field
The present invention relates to area of medical devices more particularly to a kind of loin drawing devices manually controlling tractive force.
Background technology
Traction, one of method of rehabilitation.With special leash and device, drawing practice is carried out to human body a part.Purpose
It is to increase interbody space and intervertebral foramen, releases the compressing of nerve root and the distortion of vertebral artery, alleviates muscle cramp, make the vertebra of protrusion
Disk resets.There are commonly the cervical traction for the treatment of cervical spondylosis, the pelvises of the prominent disease of lumber ertebral disc（Lumbar vertebrae）Traction and improve and
Promote the function traction of extremities joint function.Its device can utilize weight, spring scale or screw the non-machine that screw rod makees tractive force
Dynamic traction table, or using the motor traction bed of electronic device automatic control, if divided according to joint, traction can be divided into vertebra or four limbs
The traction in joint.Clinically, spinal distractor is relatively often used；And in spinal distractor, and most with lumbar traction and cervical traction
To be common, and general draft gear can not accomplish arbitrary adjusting tractive force, and only very high electronically controlled of use cost is led
Draw bed.
Invention content
The present invention is to solve the problems, such as that existing apparatus can not arbitrarily adjust tractive force and cost is higher, makes following design：
Structure of the invention includes：Waist fixing device, manual rackwork, counter weight device, supporting surface, leash；The waist is fixed
Device includes fixing strap of waist, connect band, dynamometer, and the fixing strap of waist is connect with described connect band one end, the connection
The band other end is connect with described dynamometer one end, and the dynamometer other end is connect with described leash one end；The leash
The other end is connect with the counter weight device；The supporting surface has shaft, the manual rackwork to be located at the support on one side
Face side can make the supporting surface prolong the shaft rotation, and can make the supporting surface and the angle on ground between 0 ° -90 °
Any angle is fixed；It includes counterweight box, clump weight that the supporting surface, which has sliding rail, the counter weight device, and the clump weight is loaded on institute
It states in counterweight box, the counterweight box has idler wheel, the idler wheel to be slided in the sliding rail on one side；The supporting surface has shaft on one side
Also fixed structure, the fixed structure include " u "-shaped card slot, fastening bolt, and the fastening bolt is further fixed on sucker, is convenient for
It is fixed with bedside or edge of bed；There are limit hole, the leash to pass through the limit hole on the fixed structure.
Preferably, the sliding rail has two or three, the idler wheel to have two rows or three rows, the setting of idler wheel and sliding rail that can make
It can make tractive force in the component in supporting surface direction without the gravity of stiction counteracting counter weight device between counter weight device and supporting surface
Condition it is more accurate.
Preferably, the manual regulating device includes handwheel, worm gear, worm screw, the shaft of the worm gear and the supporting surface
It is fixed, it is similar with medical hospital bed back lifting, worm screw can be driven to rotate with hand control handwheel, to drive worm gear to rotate, with
The fixed shaft of worm gear also drives supporting surface to rotate, and can be that angle 0 ° of -90 ° of any angle in ground stops reaching and adjust
The purpose of tractive force size.
Preferably, the fixing strap of waist is leather, the connect band, leash are nylon ribbon, make tractive force almost
All from elastic force of the gravity without coming from leash of counter weight device.
In conclusion the present invention can easily adjust tractive force, and because of the presence of dynamometer so that suffered by patient
Tractive force size becomes intuitive, is more convenient to adjust, and because the elasticity of material itself is not utilized to make tractive force, and patient is slight
Moving does not influence its suffered tractive force.

Fig. 2 is supporting surface partial schematic diagram of the present invention.
Specific implementation mode
Embodiment one
Structure of the invention includes as shown in Figure 1 and Figure 2：Waist fixing device, manual rackwork, counter weight device, supporting surface
7, leash 4；The waist fixing device includes fixing strap of waist 1, connect band 2, dynamometer 3, the fixing strap of waist 1 and institute
State the connection of 2 one end of connect band, 2 other end of the connect band connect with 3 one end of the dynamometer, 3 other end of the dynamometer and
4 one end of the leash connects；4 other end of the leash is connect with the counter weight device；Having on one side for the supporting surface 7 turns
Axis, the manual rackwork are located at 7 side of the supporting surface, the supporting surface 7 can be made to prolong the shaft rotation, and can make institute
The angle on the supporting surface 7 and ground any angle between 0 ° -90 ° is stated to fix；The supporting surface 7 has sliding rail 11, described with refitting
It sets including counterweight box 6, clump weight, for the clump weight loaded in the counterweight box 6, the counterweight box 6 has idler wheel, the rolling on one side
Wheel sliding in the sliding rail 11；It includes " U " that the supporting surface 7, which has shaft to also have fixed structure 9, the fixed structure 9 on one side,
Shape card slot, fastening bolt, the fastening bolt are further fixed on sucker；There are limit hole 10, the traction on the fixed structure 9
Band 4 passes through the limit hole 10.
More specifically, the sliding rail 11 has two, and the idler wheel has two rows.
