Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a spinal surgery bracket. Background Technique

[0002] When performing spinal surgery, patients often need to lie prone on the hospital bed. During the operation, the body shape of the patient on the hospital bed is usually in an arch shape to facilitate the spine to be presented in front of the doctor. Generally, a spinal bracket is used to support the patient's spine.

[0003] Chinese Patent No. CN118161371A discloses a spinal surgery bracket, which includes a support frame, an arc-shaped support plate, a synchronous adjustment mechanism, a head support, a headrest, a leg support, a leg pad and an adjustment component. The arc-shaped support plate is arranged above the support frame. There are four arc-shaped support plates, two of which are arranged on one side of the support frame and symmetrically arranged. One end of the arc-shaped support plate is hinged to the support frame through a hinge. The synchronous adjustment mechanism is arranged inside the support frame. The end of the arc-shaped support plate away from the hinge is hinged to the synchronous adjustment mechanism. The head support and the leg support are fixedly arranged on both sides of the support frame.

[0004] At present, traditional spinal surgery brackets generally have a certain adjustment function during use. For example, according to the conditions of patients with different body shapes, the position of the arc-shaped support plate can be adjusted for use, etc. However, in the actual use process, we found that there are still some deficiencies in the existing surgical brackets in the prior art. For example, the crucial arc-shaped support plate does not have a limit and blocking function. Before the anesthesia stage during the operation, considering the operation time, patients often need to move and adjust to the best position on the arc-shaped support plate before the operation. However, due to the lack of a limiting structure, it is easy for the patient's body to tilt and slide off the arc-shaped baffle on one side. Secondly, in order to improve the comfort of patients, there are arc-shaped support plates with elastic pad structures on the market at present. However, the bottom of this kind of pad is generally fixed by screws. For hospitals with a large number of surgeries, the frequent use of the bracket will inevitably cause damage to the elastic pad to a certain extent, so it needs to be replaced. And it is time-consuming and laborious to disassemble the pad from the bottom of the support plate by relying on auxiliary instruments. Content of the Utility Model

[0005] Aiming at the problems mentioned in the background technique, the purpose of the utility model is to provide a spinal surgery bracket to solve the problems mentioned in the above background technique.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

An elastic pad is arranged at the upper end of the bearing plate. A dovetail block is arranged at the lower end of the bearing plate. The bearing plate is inserted into one side of the arc-shaped support plate through the dovetail block. Mounting seats are symmetrically arranged on the outer side of the arc-shaped support plate. A baffle is slidably connected to the inner side of the mounting seat. A fixing mechanism is arranged on the inner side of the baffle. A clamping hole is formed in the inner side of the mounting seat. The baffle is clamped to the clamping hole through the fixing mechanism. The baffle is attached to one side of the bearing plate.

[0008] The fixing mechanism includes a mounting cavity. The mounting cavity is formed in the inner side of the baffle. Guide rods are symmetrically arranged on the inner side of the mounting cavity. The same movable plate is slidably connected to the outer sides of the guide rods. Springs are sleeved on the outer sides of the guide rods. A clamping block is arranged on the side of the movable plate away from the spring. The inserting end of the clamping block movably penetrates the cavity wall of the mounting cavity and is clamped to the clamping hole. A pushing block is slidably connected to the inner side of the clamping hole. One end of the pushing block is movably connected to the inserting end of the clamping block. Through the fixing mechanism, it is convenient to limit the bearing plate of the elastic pad, and at the same time, the baffle can be fixed at the arc-shaped support plate, thereby preventing the patient from slipping when adjusting the body shape.

[0009] As a preferred technical solution, dovetail grooves are symmetrically formed on one side of the arc-shaped support plate close to the mounting seat. The dovetail block and the dovetail groove are in an inserting connection. Through the dovetail groove, it is convenient to insert the dovetail block on the bearing plate.

[0010] As a preferred technical solution, mounting blocks are symmetrically arranged on the outer side of the mounting seat. The mounting blocks are fixedly installed on the arc-shaped support plate through screws. Through the mounting blocks, it is convenient to fix the mounting seat.

[0011] As a preferred technical solution, a circular groove is formed on one side of the mounting seat away from the baffle. One end of the orifice of the clamping hole is communicated with the circular groove. One end of the pushing block is arranged inside the circular groove. Through the circular groove, it is convenient to play a certain protective role for the pushing block.

[0012] As a preferred technical solution, first limiting grooves are symmetrically formed on the outer side of the pushing block. One end of the pushing block is slidably connected to the inner side of the clamping hole through the first limiting grooves. Through the first limiting grooves, it is convenient for the pushing block to be limited and slide in the clamping hole.

[0013] As a preferred technical solution, second limiting grooves are symmetrically formed on the outer side of the baffle. The baffle is slidably connected to the mounting seat through the second limiting grooves. Through the second limiting grooves, it is convenient for the baffle to be limited and slide on the mounting seat.

[0014] As a preferred technical solution, shifting grooves are symmetrically formed on the inner side of the mounting cavity. The end part of the movable plate is slidably connected to the inner side of the shifting grooves. Through the shifting grooves, it is convenient for the movable plate to slide more stably inside the mounting cavity.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] First, use the push block to push the clamping block connected to the baffle out of the clamping hole, and then press the baffle to slide it downward at the mounting seat. When the baffle does not fit against the bearing plate of the elastic pad, at this time, the bearing plate can be pushed out from the arc-shaped support plate along one side of the notch of the dovetail groove, so that the elastic pad attached to the bearing plate can be quickly disassembled and assembled for use.

[0017] Second, by pushing the baffle, the inclined surface of the clamping block on the baffle is squeezed by the lower end of the mounting seat. At the same time, the movable plate connected to the clamping block slides in the installation cavity to compress the spring. Until the position of the clamping block corresponds to the clamping hole, the spring resets to push the clamping block connected to the movable plate into the clamping hole to fix it. The two baffles protruding from the arc-shaped support plate can well prevent the patient's body from slipping when adjusting. BRIEF DESCRIPTION OF THE DRAWINGS
