Description

Spinal radian adjusting device

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, specific spine radian adjusting device who uses is rescued in spine operation and spinal injury rehabilitation that says so.

Background

As is known, a bracket is required to support the body, so that the surgical site of the back spine is fully exposed, the surgical field is expanded as much as possible, the surgical operation is facilitated, the proper curvature adjustment is required, and the bracket device capable of generating the proper radian and adjusting the radian is also required for correcting the hyperextension position of the spine.

CN2287028 discloses a spine arc adjusting device, it includes seat frame, layer board and adjustment mechanism, seat frame position frame support, its both sides vertically are equipped with the guide rail axle respectively, are equipped with a fixed establishment who uses externally on four angular positions of front and back, adjustment mechanism is double helix mechanism, and its apical axis is horizontal and couples in the guide rail epaxially, and the screw shaft is parallel with the apical axis and fixed with guide rail axle or seat frame, and the tip is equipped with the hand wheel, the layer board is the elasticity layer board strip, is the arc, fixes respectively on two apical axes, and two layer board strips can be followed the apical axis and transversely do the regulation removal, and this kind of structure has realized that layer board strip radian is adjustable, but still has following not enough: firstly, because the human bodies are different in size and the widths of the spine bones are different, the distance between the two supporting lathes cannot be adjusted in time according to the comfort level of a patient in the using process, so that the use is inconvenient; secondly, because the layer board is the elasticity lath, in the use, the layer board center does not have the support, is very easily by the heavy patient and is the reverse bending after pressing down in the process of doing the recovered correction of backbone, consequently, the structure is unreasonable, the poor stability.

Disclosure of Invention

The utility model aims at solving the defects of the prior art and providing a spine radian adjusting device which has reasonable structure, convenient use and high stability.

The utility model provides a technical scheme that its technical problem adopted is:

a spine radian adjusting device comprises a seat frame, a guide rail shaft, a nut block, a hand wheel, a rocking handle, a sliding column sleeve, a supporting plate strip, an ejector rod, a screw shaft seat block, an ejector shaft seat block, a fixed sliding block, a positioning nail, an adjusting rod, a fixed rod and a shaft seat, and is characterized by also comprising a radian adjusting and supporting mechanism which comprises a slide way, a lifting screw rod, a rotating handle and an upper connecting seat, wherein the slide way is positioned at the lower end of the nut block, the left end and the right end of the slide way are respectively and fixedly connected with the seat frame, the upper end of the slide way is transversely provided with a dovetail sliding groove, the front end and the rear end of the nut block are respectively and slidably connected with the dovetail sliding groove through a dovetail, the center of the upper end of the nut block is vertically provided with a lower threaded blind hole, the lifting screw rod is a bidirectional screw rod, the rotating handle is fixed between bidirectional threads of the, go up connecting seat upper end and layer board strip fixed connection, adjust supporting mechanism's support through the radian and adjust the layer board strip interval at will according to patient's needs in the use, reached convenient to use, effect that stability is high.

The utility model discloses owing to adopt above-mentioned structure, have rational in infrastructure, convenient to use, advantage such as stability height.
