Supporting device

Abstract

The invention relates to a supporting device. The supporting device comprises two supporting connecting blocks, wherein the two supporting connecting blocks are connected with a multi-tooth rotating shaft through inwards-concave racks at the bottom ends, T-shaped cavities are formed in the supporting connecting blocks, connecting balls are arranged at the two ends of a supporting rod, the first connecting ball is connected in the T-shaped cavity and can freely slide in the T-shaped cavity, the second connecting ball is connected with a second locking hole in the side face of a screw cap of a screw and rotates with the second locking hole as a fulcrum, a second fixing hole is formed in the upper portion of the screw cap, a fixing screw penetrates into the second connecting ball through thesecond fixing hole to prevent the second connecting ball from falling off and sliding out, and the screw penetrates through a first fixing hole of an attached steel plate to fix the attached steel plate to a protrusion of the vertebral arch of the spine; and the other side of the spine is of the same structure, the two ends of a transverse connecting bent rod are connected with first locking holesof the multi-tooth rotating shaft respectively, and the structures on the two sides are connected together. According to the supporting device, a hinge structure composed of the supporting connectingblocks and the multi-tooth rotating shaft is adopted, the protrusion of the vertebral arch serves as the supporting point, and the upper trunk of the human body can freely stretch and retract withinthe normal range.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a support device. Background technique [0002] In modern orthopedic surgery, most of the repairs for spinal injuries are fixed-spine repairs, which makes the fit gap between the spines uncomfortable, resulting in the patient's movement after recovery. The rotatable device of the spine has almost become a necessary implant for spinal repair. . Especially in the treatment of severe traumatic fractures of the spine, the fracture site is usually immobilized. [0003] The existing spinal repair methods and devices can achieve good fixation, but they have a serious impact on the activities between the spinal segments and the extension and contraction of the upper body of the human body, seriously affecting the healing of the spine and the recovery speed of the patient. [0004] Invention patents similar to spinal support devices are mostly based on wearables. Even implan...

[0003] The existing spinal repair methods and devices can achieve good fixation, but they have a serious impact on the activities between the spinal segments and the extension and contraction of the upper body of the human body, seriously affecting the healing of the spine and the recovery speed of the patient

[0004] Invention patents similar to spinal support devices are mostly based on wearables. Even implants use the intervertebral disc as the support point for spinal repair. The distance between the support points is relatively close. Most of the support devices are fixed module structures, which affect the extension of the human trunk. shrink
