Description

Technical Field

[0001] The invention relates to the field of lithotomy position auxiliary tools, in particular to an adjustable lithotomy position bed structure for urology surgery. Background Art

[0002] Urology is a hospital department that mainly diagnoses and treats diseases of the "surgical" part of the urinary system, and mainly treats various urinary diseases. Urology is a branch of medicine that specializes in the study of the male and female urinary systems and the male reproductive system. It is a sub-specialty derived from surgery. Its treatment scope includes various urinary stones and complex kidney stones; kidney and bladder tumors; prostatic hyperplasia and prostatitis; inflammation and tumors of the testicular epididymis; testicular spermatic cord hydrocele; various urinary system injuries; congenital malformations of the urinary system, such as hypospadias, cryptorchidism, and hydronephrosis caused by stenosis of the ureteropelvic junction.

[0003] When conducting relevant examinations in urology, the patient needs to be in the lithotomy position. In order to keep the patient in the lithotomy position, many lithotomy operating tables have appeared in the prior art, such as:

[0004] 1) Publication No. CN114376844B discloses a lithotomy position operating bed. In this application, the operating bed includes a support seat and a bed body arranged on the support seat, two sets of leg support mechanisms are arranged on the bed body, the leg support mechanism includes a connecting seat, a sliding rod, a fixed seat, a sliding seat, a hinged plate 1 and a hinged plate 2, the connecting seat is arranged on the bed body for vertical rotation, one end of the sliding rod is arranged on the connecting seat for horizontal rotation, the fixed seat is fixedly arranged on the sliding rod, the sliding seat is slidably connected to the sliding rod along the length direction of the sliding rod, one end of the hinged plate 1 is hinged to the fixed seat, and the other end is hinged to the hinged plate 2, the hinged plate 2 is hinged to the sliding seat relative to the other end of the hinged plate 1, a first driving mechanism for driving the connecting seat to rotate and a second driving mechanism for driving the sliding rod to rotate are arranged on the bed body, and a third driving mechanism for driving the sliding seat to slide is arranged on the sliding rod. The lithotomy position operating table of the present application can realize free switching between the lithotomy position and the supine position, and there is no need to disassemble and assemble accessories such as leg boards, which greatly reduces the workload of medical staff and improves work efficiency.

[0005] 2) Publication No. CN116919761A discloses a lithotomy position operating table with a torso posture actively adjusted with leg movement. In this application, the operating table includes bed legs, bed feet, a fixed bed body, a movable bed body that can move in a translational direction along the length direction of the fixed bed body, a bifurcated plate rotatably mounted at the end of the fixed bed body, a bent leg slide groove opened along the length direction of the bifurcated plate, a bent leg slider slidably mounted in the bent leg slide groove, a double-leg telescopic driving assembly, a bent leg deformation plate mounted above the bifurcated plate, and a double-leg bifurcated driving assembly that drives the bifurcated plate to rotate relative to the fixed bed body; the double-leg telescopic driving assembly is used to drive the bent leg slider and the movable bed body to move synchronously in the opposite direction, thereby realizing the mutual transformation of the bent leg deformation plate between the flattened state and the bent leg deformation state. The present invention is a lithotomy position operating table with a reasonable structure, which can realize the active adjustment of the horizontal position and inclination angle of the patient's torso during the leg bending process, thereby making the patient's lithotomy position state more standard.

[0006] 3) Publication No. CN110368251 B discloses an operating table which can be automatically adjusted from a supine position to a lithotomy position. In the application, the operating table includes a base, a support, a head bed board, a lumbar bed board, a thigh bed board, a calf bed board, an adjustment mechanism, a turbine screw lift and a stepper motor; the calf bed board is jointly acted on by the turbine screw lift, a spherical universal joint and a double-section retractable universal joint, and then the second thigh bed board is connected by a single-section universal joint. The distance between the second thigh bed board and the first thigh bed board is automatically adjusted by the extension and contraction of a gas spring, so that the supine position can be automatically converted into a lithotomy position without the need for a leg stand. The thigh leg board strap and the calf leg board strap are designed as an inwardly concave arc structure, which is easy to fix the patient's position and increase the patient's comfort, making it very convenient for patients undergoing combined perineal and rectal cancer resection, intrauterine balloon hemostasis after cesarean section in obstetrics and gynecology, etc. to adjust their position, with high work efficiency, reducing the patient's pain and medical expenses.

[0007] The above-mentioned prior arts disclosed are all instruments specially used for lithotomy position. Although they can achieve technical effects such as adjusting the state of the patient's legs, the horizontal position of the body, lithotomy position and supine position through the structure, they all adopt an integrated structure, that is, the structure for adjusting the lithotomy position and the bed frame are an integrated structure. Although the integrated structure does not need to be installed when in use, the entire bed body needs to be transported during transfer and transportation. Moreover, when the bed frame of this lithotomy position operating bed is damaged, the lithotomy position operating bed will become unusable. In addition, since there are many idle ordinary beds in the hospital, it is particularly critical to transform the idle ordinary beds into a bed structure suitable for the lithotomy position.

[0008] Based on this, 4) Publication No. CN209107955U discloses a lithotomy leg stand. In this application, the lithotomy leg stand includes a side rail clamp, an eccentric locking structure, and a leg support locking structure. The side rail clamp includes a side rail clamp body, an adjustable clamping block, and a handle assembly. The side rail clamp is provided with a pad groove, and the pad groove is used to place the pad; the eccentric locking structure includes a locking device, a hemispherical bearing, an eccentric shaft, and an eccentric push rod. The eccentric push rod includes a top plate, a connecting rod, a compression spring, and a tail push column from top to bottom, and the top plate is hinged to the connecting rod. The leg stand of the utility model is more stable in clamping, adapts to different operating bed side rails, eliminates the tangential force of the eccentric wheel on the push rod, and extends the service life of the leg stand. A compression spring is provided at the lower end of the eccentric push rod to offset the excess stroke of the eccentric wheel and prevent damage to the locking device. The leg support can be adjusted with multiple degrees of freedom.

[0009] The above-mentioned prior art 4 adopts a leg frame structure, which can be connected and installed with structures such as a hospital bed, and can realize leg adjustment, but this leg frame structure is relatively simple and requires additional configuration of positioning pads, shoulder pads and other tools when used. At the same time, it cannot adaptably adjust the thighs and calves. Summary of the invention
