Abstract
The utility model provides a lumbar traction instrument capable of adjusting bidirectionally. One end of a stroke rack is connected with an upper connection plate through a sheath; a stroke rack bracket is arranged on a lower connection plate; the stroke rack is sleeved in a chute of the stroke rack bracket; a driving ratchet wheel is arranged at the top of an adjusting rod, and is fixed on the stroke rack bracket through a hinge shaft and forms a meshing pair with the stroke rack; a stress application pawl and a release pawl are respectively hinged on the stroke rack bracket and form a rack wheel-pawl traction force adjusting mechanism with the driving ratchet wheel. Through the adoption of the traction force adjusting mechanism with the ratchet wheel-pawl structure, the traction force is increased or decreased only through an adjusting handle, so that the traction therapy operation process is simplified, the traction malposition phenomenon due to improper handling is reduced, and the traction therapy effect is guaranteed.
Description
Technical field
This utility model is to the improvement of existing lumbar traction instrument structure, discloses a kind of two-ways regulation lumbar traction instrument, belongs to technical field of medical instruments.
Background technology
The size adjustment of existing lumbar traction instrument pull strength is to separate the governor motion that is provided with by two covers to finish, the increase of pull strength or reduce to operate respectively different operating grips and just can finish, because this governor motion is positioned at physical therapy person's both sides, so physical therapy person operates very inconvenience, often cause the draft gauge dislocation, influence physiotheraping effect, serious also can increase the weight of spinal cord injury, does not reach the physical therapy purpose.
Summary of the invention
This utility model provides a kind of two-ways regulation spinal distractor instrument, and the pull strength increase and decrease adjustment structure that has solved existing spinal distractor instrument is separated the unhandy problem that brings that is provided with.
Technical solution of the present utility model is as follows: an end of stroke tooth bar is connected with upper junction plate by sheath, lower connecting plate is provided with stroke tooth bar support, the stroke rack tube is contained in the chute of stroke tooth bar support, the top of adjusting rod is provided with Drive ratchet, be fixed on the stroke tooth bar support with the stroke tooth bar by hinge and constitute Meshing Pair, afterburning pawl axis is connected on the middle part of adjusting rod, discharge ratchet and be hinged on the stroke tooth bar support, afterburning pawl, release piece constitute the click draught control mechanism with Drive ratchet respectively.
With upper junction plate and lower connecting plate relative fixed, when regulating handle when direction is rotated, under afterburning ratchet effect, drive ratchet and rotate, drive the stroke tooth bar to top offset, the human body lumbar vertebra is increased pull strength; When pulling regulating handle and rotate round about, drive the ratchet backward rotation under the ratchet effect discharging, drive the stroke tooth bar to bottom offset, reduce pull strength to the human body lumbar vertebra.
Good effect of the present utility model is: the pull strength guiding mechanism that adopts the click structure, can realize the increase of pull strength or the adjustment of minimizing by a regulating handle, simplified the operating process of traction physical therapy, reduced because of misoperation causes drawing inconsistent phenomenon and taken place, guaranteed the traction physiotheraping effect.
Description of drawings
Fig. 1 is this utility model structure principle chart.
The specific embodiment
According to shown in Figure 1, constitute this utility model by upper junction plate 1, lower connecting plate 6, stroke tooth bar 7, upper junction plate 1 is provided with sheath 4, an end of stroke tooth bar 7 be set with pressure guide spring 3 and by bolt 2 fixtures in sheath 4; Stroke tooth bar support 5 is fixed on the lower connecting plate 6, and stroke tooth bar 7 is sleeved in the chute of stroke tooth bar support 5; The top of adjusting rod 9 is provided with Drive ratchet 8, afterbody is for holding the puck 10, be fixed on the stroke tooth bar support 5 with stroke tooth bar 7 by hinge and constitute Meshing Pair, afterburning ratchet 12 is coupling at the middle part of adjusting rod 9, discharging ratchet 11 is hinged on the stroke tooth bar support 5, its emission surface is arranged in the rotational travel of adjusting rod (9), and afterburning pawl 12, release piece 11 constitute the click draught control mechanism with Drive ratchet 8 respectively.
