Description

Postoperative care brace for preventing spinal deformity from being damaged secondarily Technical Field The invention relates to the field of medical equipment, in particular to a postoperative care support for preventing secondary injury spinal deformity. Background Spinal deformity surgery is a treatment means for correcting abnormal curvature (such as scoliosis, kyphosis and the like) or serious structural abnormality, is generally suitable for the situation that conservative treatment is ineffective or illness progress threatens cardiopulmonary function and nerve function, and after spinal deformity surgery, a brace (orthosis) is an important auxiliary tool and is mainly used for protecting a surgery part, maintaining correction effect, promoting bone fusion and preventing deformity recurrence. For example, chinese patent application with publication number CN216676052U discloses a nursing brace after side-open spinal deformity surgery, the device changes the dressing of patient through the dressing change device, so that the dressing change efficiency is quickened, and simultaneously pain of patient can be reduced, and meanwhile, the possibility that the medicine falls off when just dressing can be greatly reduced, when the patient needs to ventilate the body, the patient ventilates the inside of the device by controlling the ventilation device, and bad symptoms such as dampness, sore and bacteria are avoided when the patient wears the device for a long time. The existing nursing brace used after spine operation can improve the convenience of changing dressings to a certain extent when in use, however, the nursing brace used after operation needs to keep a certain physiological curve, so that the protection effect of the spine used after operation is guaranteed, the nursing brace used after operation needs to keep fit with the outer side of the spine to reduce the risk of secondary deformation of the spine, certain differences exist in spine operation positions and physiological curves of patients of different types, the existing nursing brace is difficult to finely adjust the bending angle, and the nursing brace used after operation can not be in good contact with the outer side of the spine, so that adverse effects can be caused on the protection effect of the spine. Disclosure of Invention Aiming at the problems that the nursing support in the prior art is difficult to finely adjust the bending angle and can not be well contacted with the outer lateral direction of the spine so as to cause adverse effect on the protection effect of the spine, the deformation amplitude of the backing plates at different positions can be adjusted by arranging a plurality of groups of cams which are distributed in parallel, so that the functionality and the flexibility of the nursing support in the use process can be further improved. In order to solve the problems, the invention adopts the following technical scheme: The utility model provides a prevent secondary injury backbone deformity operation postoperative nursing brace, includes the support frame, the mounting groove has been seted up to support frame one side surface embedding, be provided with the design subassembly in the mounting groove, the design subassembly is including setting up the closing plate in the mounting groove, sliding connection has a plurality of supporting seat on the closing plate, every fixedly connected with traction lever in the supporting seat, traction lever one end fixedly connected with movable sleeve, movable sleeve internal rotation is connected with the spheroid, the traction lever other end is connected with the spheroid, the spheroid overcoat is equipped with the movable sleeve, and adjacent traction lever is the rectilinear connection through the movable sleeve that spheroid and spheroid overcoat were established, the quantity of movable sleeve, spheroid and traction lever is a plurality of group. Optionally, the movable sleeve is ring form, one side is equipped with the backing plate in the mounting groove, the supporting seat all contacts with backing plate one side surface with movable sleeve surface, backing plate and closing plate all adopt flexible ventilative material to make, movable sleeve and spheroid adopt light wear-resisting material to make, the support frame outward appearance is circular-arc and adopts light material to make. Optionally, the outside of the traction lever that is located both ends is provided with adjusting component, adjusting component includes the regulation pole of being connected with the traction lever of one end, the regulation pole runs through outside the supporting seat and with the supporting seat rotation connection, mounting groove one end internal surface fixedly connected with spiral shell, spiral shell internal surface with connect the traction lever threaded connection of regulation pole.
