Description

Technical Field

[0001] This utility model relates to medical auxiliary devices, and in particular to a straddle-type standing chair for surgical procedures. Background Technology

[0002] Surgeons typically perform surgery standing up, and prolonged standing can lead to conditions such as lumbar muscle strain, knee and hip pain, and varicose veins in the lower extremities. However, doctors still rarely perform surgery while seated. Factors to consider include: sitting increases the distance between the surgeon's upper body and the operating table, and it makes it difficult for the surgeon to change their perspective and adjust their posture during surgery.

[0003] Utility model patent CN209377772U discloses a straddle-type standing chair for surgical or experimental procedures. This utility model employs a straddle-type seat and triangular base to save space as much as possible. A pneumatic lifting rod, height adjustment pedal, and self-resetting universal ball joint allow users to flexibly adjust the height, horizontal rotation angle, and tilt of the chair, enabling it to move with the user's posture for a better fit. When seated, the gravity brake wheel locks under pressure, fixing the chair relative to the ground and preventing tipping. When standing, the chair can be easily moved with the user using the legs. However, because this utility model uses a universal ball joint, the seat cushion tilts, making it difficult to maintain a fixed position. During use, medical personnel inevitably experience slight body swaying, causing a shift in the center of gravity. This causes the seat cushion to tilt as well, resulting in poor stability and an inability to maintain a fixed position, negatively impacting the user experience. Summary of the Invention
