an operation method of a dismantling-free lithotomy position leg-frame bed comprises the following steps:
the method comprises the following steps: when the two deformable leg frames 2 are in an undeformed state, the leg frame bed is used as a normal operating bed;
step two: before operation, a patient lies on a leg-supporting bed, the head of the patient is positioned above a headrest 4, the upper half of the patient is positioned above an upper half bed body 1, two legs of the patient are respectively positioned on two deformable leg supports 2, thighs of the patient are positioned above a thigh supporting plate 201, and the calves of the patient are positioned above a calf supporting plate 202;
step three: the two thigh supporting plates 201 can be adjusted to be opened at a certain angle on the plane of the cross section of the upper body bed body 1 through the rotating shaft assembly 3, and the opening angle is locked through the control handle rod 304;
step four: the lower leg support plate 202 can be adjusted to rotate in the sagittal plane through the movable shaft assembly 6 and is locked in position through the second threaded lock 603;
step five: the shank supporting plate 202 can be adjusted to move along an arc-shaped movement track on the plane where the longitudinal section of the shank supporting plate 201 is located by the telescopic sleeve 203 with a certain point as a circle center and is locked by the first threaded locking part 2033, so that the shank supporting plate 202 is lifted in the air and lifted, and the patient lifts the two legs to keep the lithotomy position;
step six: the position of the sliding support plate 2022 in the drawer support plate 2021 is adjusted according to the leg length of the patient, the sliding support plate 2022 is pushed towards the head side of the drawer support plate 2021 by pushing the sliding support plate 2022, after the proper position is reached, the anti-slip lattice blocking piece 2025 abuts against one of the ratchets on the ratchet layer 2024, and the sliding support plate 2022 cannot move towards the foot side of the drawer support plate 2021, so that when the patient is in a state that the shank is raised at the lithotomy position and the thigh is suspended, the sliding support plate 2022 can push towards the head side of the patient to abut against the popliteal fossa;
step seven: after the leg-supporting bed is deformed, starting the operation;
step eight: after the operation is finished, resetting is carried out;
firstly, the anti-slip grid block sheet 2025 is manually rotated, the anti-slip grid block sheet 2025 is separated from the ratchet layer 2024, and the sliding support plate 202 moves towards the foot side of the drawer support plate 2021 to reset;
then, the first threaded locking member 2033 is unlocked, the shank support plate 202 is adjusted to reset through the telescopic sleeve 203, and the shank support plate is locked by the first threaded locking member 2033 after the reset is completed;
then, the second threaded locking member 603 is unlocked, the movable shaft assembly 6 is used for adjusting the shank supporting plate 202 to reset, and the second threaded locking member 603 is locked after the resetting is finished;
finally, the control handle rod 304 is rotated, the two thigh supporting plates 201 are adjusted through the rotating shaft assembly 3 to reset, and after the resetting is completed, the leg support bed can be continuously used as a normal operation bed through the control handle rod 304 to be locked.
The present invention has been described in detail with reference to the above examples, but the description is only for the preferred examples of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
