Detailed Description

As shown in fig. 1-2, a spinal surgery positioning and guiding system comprises a waist board 1 for fixing with waist and a back board 2 for fixing with back, wherein a guiding mechanism is arranged above the waist board 1 and the back board 2. The waist board 1 and the back board 2 are fixed to the human body in many ways, but mainly adopt a bundling form, for example: the back plate 2 and the waist plate 1 are both provided with a binding belt 22. The binding band 22 can be an elastic band, which can be directly tied together, or can be connected together by using a fastening band, a connecting buckle, etc. In order to improve comfort, the inner surfaces of the waist board 1 and the back board 2 are usually provided with cushion layers, in the invention, in order to avoid graphic interference, designers can carry out ergonomic design according to actual conditions to ensure stable attachment and ventilation. Of course, since the back plate 2 is installed on the back of the human body, in order to avoid the interference of the arms, the arm slots 21 for the arms to pass through are symmetrically arranged on both sides of the back plate 2.

The guiding mechanism is used for drawing the lumbar plate 1 and the back plate 2 so as to realize the guidance of the spine. As shown in fig. 1, the guiding mechanism includes a threaded sleeve 3, the bottom of the threaded sleeve 3 is connected with the upper end of a mounting rod 4, the lower end of the mounting rod 4 is hinged with the upper end of a first hinged seat 5, and the first hinged seat 5 is arranged on the waist board 1. An adjusting rod 6 penetrates through the screw sleeve 3, the adjusting rod 6 and the screw sleeve 3 form threaded fit, one end of the adjusting rod 6 is connected with the driving assembly, a connecting rod 7 is arranged at the other end of the adjusting rod 6, and the connecting rod 7 is hinged to a second hinge seat 0 arranged on the back plate 2. And a section of the connecting rod 7 between the threaded sleeve 3 and the connecting rod 7 is provided with a rotary joint 8. The rotary joint 8 is a joint with two ends capable of rotating relatively, and can ensure that the two sections of the adjusting rod 6 rotate, so that the interference of the adjusting rod 6 on the connecting rod 7 in the rotating process is avoided.

In the using process of the invention, a patient firstly fixes the waist plate 1 and the back plate 2 at the waist and back positions respectively, then lies on the sickbed, and then connects the guide mechanism with the waist plate 1 and the back plate 2 respectively, so that the normal positioning guide treatment can be carried out, specifically, the adjusting rod 6 is rotated, the adjusting rod 6 can carry out the position adjustment relative to the screw sleeve 3 in the rotating process, and the adjusting rod 6 can not influence the other end in the rotating process due to the existence of the rotary joint 8. In the action process of the adjusting rod 6, the adjusting rod can pull the back plate 2 to lift, so that the positioning and guiding of the spine are realized, and the control of the traction amount and the traction angle can be effectively realized by controlling the rotating speed and the rotating amount of the adjusting rod 6, so that the invention has convenient use and good treatment effect.

In the specific use process, because the tolerance degree of each patient has large difference, if the adjusting rod 6 is integrally a rigid support rod, in the action process, if the operation is improper, secondary damage to the patient is possible due to no buffer allowance, therefore, the invention is better to make a section of the adjusting rod 6 between the rotary joint 8 and the connecting rod 7 be formed by the buffer spring 9. The coaxial short rod 10 that is provided with of one end that leaves swivel joint 8 away from swivel nut 3, the one end that swivel joint 8 was kept away from to short rod 10, the one end that articulated seat 0 of second was kept away from to connecting rod 7 to and buffer spring 9's both ends all are provided with ring flange 11, constitute flange joint between short rod 10 and the buffer spring 9, between connecting rod 7 and the buffer spring 9. Through the arrangement of the buffer spring 9, the invention changes the stored rigid transmission into certain flexible transmission, so that the comfort is better, and the invention has certain buffer allowance, and even if the operation is proper, the influence can not be caused.

Meanwhile, in order to further improve the stability of the rotation of the adjusting rod 6, a bearing sleeve 12 is further sleeved outside a section of the adjusting rod 6 between the threaded sleeve 3 and the rotary joint 8, the bearing sleeve 12 and the adjusting rod 6 form a rotating fit, and the bearing sleeve 12 is connected with the mounting rod 4 through a connecting lever 13. In order to facilitate the driving of the adjusting rod 6 to rotate, the driving assembly comprises a rotating disc 14 arranged at the end of the adjusting rod 6, and a handle 15 is arranged on the rotating disc 14. Of course, it is possible to replace the drive assembly with other structures that serve the same purpose, such as crank handles, screwheads, etc.

In order to adapt to different crowds, the installation positions of the back plate 2 and the waist plate 1 are different, for this reason, the first hinge seat 5 and the second hinge seat 0 of the invention are detachably connected with the waist plate 1 and the back plate 2, and the specific structure form can be that the tops of the waist plate 1 and the back plate 2 are both provided with a connecting cylinder 16, and the first hinge seat 5 and the second hinge seat 0 both comprise an inserted bar 17 matched with the connecting cylinder 16 and a U-shaped hinge part 18 arranged at the upper end of the inserted bar 17. Be provided with round pressure disk 19 on the global of inserted bar 17 middle section, one section that inserted bar 17 is located pressure disk 19 top still overlaps outward and is equipped with fastening cap 20, fastening cap 20 and inserted bar 17 normal running fit. The inside wall of fastening cap 20 is provided with the internal thread, the lateral wall of connecting cylinder 16 is provided with the external screw thread, constitute screw-thread fit between fastening cap 20 and the connecting cylinder 16. The fastening cap 20 is screwed to the connecting tube 16, so that the insertion rod 17 is tightly pressed into the connecting tube 16 by the fastening cap 20. In addition, the flange connection, the sucker bonding and other modes are adopted, and the assembly and disassembly are feasible on the premise of meeting the disassembly and assembly convenience.
