[0003] The most common body position in gynecological diagnosis and treatment is lithotomy position. Lithotomy position is that the patient's legs are placed on the support, the hips are on the seat cushion, and the back is against the backrest. According to the needs, the backrest will be adjusted within a certain angle. When lying flat, as the backrest rotates upward, a forward pushing force is generated on the human body, and at the same time, the patient's abdomen is squeezed under the condition that the hips and lower body are basically not moving, especially for special patients such as pregnant women. During the process of the backrest rotating upward, the patient will move the body to move the hips away from the backrest to offset the squeezing, but for patients who are not convenient, they need the assistance of medical staff, which is very cumbersome. SUMMARY

[0007] a base;

[0008] a backrest hinged to the base for supporting the back of a patient;

[0009] an angle adjusting mechanism comprising a driving assembly and a telescopic rod, one end of the telescopic rod being connected to the driving assembly and the other end being fixedly connected to the backrest;

[0010] a controller electrically connected to the driving assembly and controlling the operation of the driving assembly, and the driving assembly drives the telescopic rod to extend or retract and drives the backrest to rotate, thereby assisting the patient to lie flat or lie down;

[0011] a seat cushion slidably connected to the base for supporting the hips of a patient;

[0012] A gas spring is fixedly connected with one end of the base and the other end of the cushion;

[0013] A support is fixedly connected with the cushion and used for supporting the legs of the patient.

[0014] Further, the bottom of the cushion is provided with a pair of sliding blocks, and a pair of sliding rails are arranged above the base, the pair of sliding blocks and the pair of sliding rails are in one-to-one correspondence and are slidably connected with each other.

[0016] Further, the sliding direction of the cushion is consistent with the extension and contraction direction of the gas spring.

[0017] Further, the pair of sliding rails are symmetrically arranged about the gas spring.

[0018] Further, the gas spring is located between the base and the cushion, and the gas spring is arranged in a spaced manner with the base.

[0019] Further, the base is provided with an opening, and when the patient is in a lying state, the telescopic rod passes through the opening.

[0020] Further, a hinge is arranged between the backrest and the base.

[0021] Further, one end of the base is provided with a foot pedal, and the foot pedal is electrically connected with the controller.

[0023] Compared with the prior art, the utility model has the advantages that:

[0024] 1. By the sliding connection between the cushion and the base, before use, the patient's hips are located on the cushion, and the back is leaned against the backrest, when the controller controls the driving assembly to start, the driving assembly drives the telescopic rod to extend, and the telescopic rod pushes the backrest to rotate in the process of extension, and the patient slowly changes from a lying state to a lying state, since the cushion and the base are slidably connected, when the patient slowly changes from a lying state to a lying state, the backrest will generate a forward thrust on the human body, at this time, the patient's hips drive the cushion to move forward synchronously, thereby avoiding the abdominal compression, improving the patient's comfort, and avoiding secondary injury.

[0025] 2. A gas spring is used, with one end fixedly connected to the base and the other end fixedly connected to the seat cushion. The sliding direction of the seat cushion is consistent with the extension and retraction direction of the gas spring. As the patient's buttocks move the seat cushion forward in sync, the resistance of the gas spring must be overcome. The purpose is that when the patient gets off the gynecological examination chair or when the chair is not in use, the gas spring pulls the seat cushion back to its initial position for reset, ready for the next use.

[0026] 3. By fixing the support for the patient's legs to the seat cushion, the support moves forward synchronously with the seat cushion as the patient's buttocks move forward. If the support is fixed to the base alone or remains stationary, the patient's legs will be subjected to additional pressure as the buttocks move forward with the seat cushion because the patient's legs are fixed to the support. Therefore, it is necessary to fix the support to the seat cushion to avoid the patient's legs being subjected to additional pressure. Attached Figure Description
