Description

Lithotomy position operating table

Technical Field

The invention relates to the field of medical instruments, in particular to an operation table for an lithotomy position.

Background

The lithotomy position is the most common position for the pudendum operation, the patient lies on the back on the examination bed, the buttocks are close to the bedside and placed on the leg support, the perineum can be exposed to the maximum extent, and the lithotomy position is the common position for the rectum, anorectal and urinary surgery and gynecological examination.

As shown in fig. 1, an operating table for a lithotomy position generally comprises a base 001, a bed body 002 is mounted on the base 001, two leg plates 003 are detachably mounted at the tail end of the bed body 002, and leg supports 004 are detachably mounted on two sides of the tail end of the bed body 002. Before an operation is performed, a patient can lie on the bed body, wherein the two leg plates support the legs of the patient, when a doctor prepares the work before the operation (such as anesthesia and the like), the legs of the patient can be lifted from the leg plates and separated, the legs are finally supported on the two leg supports respectively so as to place the lithotomy position of the patient, and then the leg plates arranged at the tail part of the bed body are detached so as not to obstruct the operation, so that the corresponding operation can be performed.

However, in the actual operation process, that is, when the operation is completely completed, the lithotomy body position of the patient needs to be immediately released to wait for the patient to be awake, at this time, the leg plate which is removed needs to be reinstalled again, and the two legs of the patient can obtain the support (comfortable and safe position) in the flat state, so that 2 nurses are needed to assist, the weight of one leg plate is 9.8kg, the weight of two leg plates of each operation bed is 19kg, and the nurses have to disassemble and assemble the leg plate for many times along with the increase of the lithotomy body position release times, so that the operation process is very complicated, the operation process is not smooth, and the physical strength of the personnel is very high. If the operation times of the operating room on the same day are arranged more, the nurse staff is required to disassemble and assemble the leg plate for many times, so the above-mentioned work difficulty is also faced.
