Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a plantar surgery position fixing device. Background Art

[0002] Plantar surgery belongs to minor outpatient surgery, which can be operated on an outpatient operating table. The operation method is to lay an operating sheet on the operating table, let the patient lie prone on the operating table, and place a pillow covered with an operating sheet at the position of the foot, put the patient's dorsum of the foot on the pillow, and then perform the operation. However, the height of the pillow cannot be adjusted to any desired position, which is not convenient for the doctor to operate and also makes the patient feel uncomfortable.

[0003] In view of the above defects, a plantar surgery fixing device has emerged on the market. The device includes a support component arranged on one side of the operating table and capable of moving up and down. The height of the support component can be adjusted to any position within the allowable range. However, there are still some deficiencies: the existing plantar surgery fixing device can only adjust the height. When performing surgery on the feet of different patients on different sides, it is impossible to conveniently adjust the position of the support component on the operating table. Moreover, the existing support component only supports the patient's feet and does not support the legs, so that the patient's calves are always suspended during the operation, bringing great discomfort to the patient. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a plantar surgery position fixing device in view of the above defects, which can not only support the patient's feet and calves at the same time, but also conveniently adjust the position of the support component on the operating table and the angle of the leg support plate.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a plantar surgery position fixing device, including a support component arranged on one side of the operating table. The support component includes a connection block detachably connected to one side of the operating table, a first support rod detachably connected to the connection block, and a foot support plate fixedly connected to the upper end of the first support rod. The foot support plate is horizontally arranged. One end of the foot support plate is rotatably connected to a leg support plate. A second support rod is connected between the leg support plate and the first support rod. The second support rod can expand and contract as the leg support plate rotates. After the connection block and the operating table, the first support rod and the connection block, and the second support rod expand and contract, they are all fixed by fasteners.

[0006] Compared with the prior art, the advantages of this solution are as follows:

[0007] (1) The connecting block is detachably connected to one side of the operating table. The foot support plate is fixedly connected to the upper end of the first support rod, and the first support rod is detachably connected to the connecting block. After the patient lies on the operating table, the support assembly can be adjusted according to the specific situation of the patient. The position of the support assembly on the operating table is adjusted by sliding the connecting block, and the height of the foot support plate is adjusted by sliding the first support rod up and down. The adjusted height and position of the support assembly will not only make the patient feel uncomfortable, but also facilitate the doctor's operation.

[0008] (2) Since the patient needs to maintain a knee-flexed prone position on the operating table during foot surgery, when performing surgery on the sole of the foot placed on the foot support plate, the calf is in a suspended state, and the patient will feel uncomfortable. The leg support plate provided at one end of the foot support plate can support the patient's calf, avoiding the state of the calf being suspended for a long time, thereby avoiding discomfort to the patient.

[0009] (3) The leg support plate is rotatably connected to the foot support plate, and a second support rod that can expand and contract as the leg support plate rotates is connected between the leg support plate and the first support rod. When placing the patient's calf on the leg support plate, the inclination degree of the leg support plate can be adjusted according to the patient's body type to avoid discomfort to the patient.

[0010] A further preferred solution of the present utility model is that limit plates for preventing the patient's calf from slipping laterally are respectively provided on both sides of the leg support plate.

[0011] The beneficial effect of this solution is that limit plates are respectively provided on both sides of the leg support plate to prevent the patient's calf from slipping outward from both sides of the leg support plate during the operation, thereby driving the foot of the patient undergoing surgery to slip, which not only affects the progress of the operation, but also causes unnecessary harm to the sole of the patient's foot.

[0012] A further preferred solution of the present utility model is that a strap is provided at one end of the leg support plate close to the foot support plate.

[0013] The beneficial effect of this solution is that after placing the patient's calf and instep on the leg support plate and the foot support plate respectively, the patient's ankle is fixed by the strap provided at one end of the leg support plate close to the foot support plate to avoid the movement of the patient's calf and foot in the vertical direction during the operation, thereby avoiding affecting the progress and effect of the operation.

[0014] A further preferred solution of the present utility model is that the foot support plate, the leg support plate and the limit plates are all made of hard materials, and coating layers are provided on the foot support plate, the leg support plate and the limit plates, and the coating layers are all made of flexible materials.

[0015] The advantages of this solution are as follows: The foot support plate, the leg support plate, and the limit plate are all made of hard materials, which can bear a large weight and will not be easily damaged. They play a role in supporting and limiting the patient's foot and calf respectively. The foot support plate, the leg support plate, and the limit plate are all provided with a coating layer made of soft materials, which can prevent the patient from being additionally injured when accidentally colliding with the leg support plate, the foot support plate, or the limit plate.
