Spinal orthosis common in the market and Therapeutic Method, adopt nail-stick system more, such as:
Chinese patent, with the spinal column correction bar of elastic construction, (application number: 201110211414.5), provides a technical scheme: spinal column correction bar comprises stub, long rod, connecting bolt and contiguous block; Described stub one end is provided with resilient sleeve, and described resilient sleeve is circumferentially cut with elastic groove, and all elastic grooves are communicated with by described circular hole; The excellent one end of described length is provided with endoporus, and for being connected with stub, described external screw thread is connected with the female thread of contiguous block; Described connecting bolt is set to round bar shape, is provided with rectangular cylinder boss in the middle part of described connecting bolt, and connecting bolt tail end is provided with one section of external screw thread, closes with the corresponding threaded holes bottom stub resilient sleeve endoporus; The outer end of the step through-hole of described contiguous block is provided with one section of female thread, is connected with one section of external screw thread of long excellent one end; Contiguous block is provided with one section of external screw thread, matches with the female thread in stub resilient sleeve.
Chinese patent, a kind of spinal orthosis and using method (application number: 201110006480.9) thereof, a kind of spinal orthosis is described in patent, comprise growing rod and slip pedicle nail, described growing rod comprises at least two rod members, each described rod member sequential vertically, and described in adjacent two, rod portion is stacked, and overlapping part runs through at least two collars, each described collar and a described rod member are fixed.
Chinese patent, (application number: 200520146918.3), describes a kind of spine orthopedic nail to spine orthopedic nail, and shape, in " C " shape, is made up of Nitinol, and nail has aduncate spike-tooth with it.
Above-mentioned three technical schemes all can carry out backbone correcting to a certain extent, but it fixing easily causes spinal cord injury, causes disorganization, along with larger risk.
Utility model content
The purpose of this utility model is the deficiency for the existence in existing spinal orthosis and Therapeutic Method, provides the spinal orthosis that a kind of worm and gear coordinates.
Technical solution adopted in the utility model is:
The spinal orthosis that worm and gear coordinates, comprises casing, worm gear, catch and worm screw; Casing one end overarches, and opening is arranged at arch top, and casing has into cylindrical hole near arcuate part according to arch radian, hole penetrates casing, the casing other end is cuboid, and cuboid and face, hole place have duct between vertical two sides, communicate between hole and duct; Be gear structure in the middle of worm gear, gear two ends are screwed cylinder, and the round heart in cylinder two end and the gear center of circle are located along the same line, and the gear structure in the middle of worm gear is arranged in casing hole; Catch is circular, and outside diameter is identical with the diameter in casing duct, and interior circular diameter is more than or equal to worm screw diameter; Worm screw entirety is cylinder, and worm screw mid portion has screw thread, and screw thread place diameter of a circle is greater than circular diameter in catch, and the gear mechanism on the shape of screw thread, spacing and worm gear matches; Worm screw intermediate thread part is arranged in the duct of casing, and catch is fixed on two ends, duct.
Further, worm screw is hollow, and hollow space is column, and its upper and lower surface is regular hexagon.
Further, each marginal portion of casing is designed arc-shaped appearance.
Further, gear two ends screw thread is arranged in pairs or groups mutually with adjusting rod, and the diameter of adjusting rod is 6.35-4.5mm.
The advantage that this utility model has and good effect are:
The spinal orthosis that worm and gear of the present utility model coordinates has the effect of correcting scoliosis, lift, both adjusting rod work can be coordinated, the demand coordinated with nail rod can be met again, implant easy, handling safety, the hommization of worm and gear matching design, reduces risk human body being caused to damage, solves the drawback to age requirement in spine corrective operation.
