The devices cannot be raised and lowered and rotated according to the actual needs of the operation, thereby failing to meet different limb placement needs and having low applicability. In addition, the existing limb placement devices for obstetrics and gynecology surgeries (such as the utility model with application number 202121103816.9) generally use a semi-open semi-circular arc fixing plate to place and fix the limbs, which cannot effectively limit the limbs and can only limit one side of the limb, causing the limb to easily detach from the opening of the semi-circular arc fixing plate on the other side, and having low practicality. Therefore, the utility model proposes a limb placement device for obstetrics and gynecology surgeries to solve the problems existing in the prior art. Utility Model Content

[0006] The yoke is secured to the bottom of the support frame and is secured on a 40-degree angle to the top of the support frame, the yoke being secured to the bottom of the support frame and being secured to the bottom of the support frame by a second means.

[0007] Further improvement lies in that: the first positioning mechanism includes positioning pins that slide through the front and rear sides of the support plate and positioning holes that are opened at the bottom end of the placement plate and are equidistantly distributed in a circular shape. Cavities are opened on the front and rear sides inside the support plate. A pressure plate is fixed on one side of the positioning pin located in the cavity, and the bottom end of the pressure plate is connected to the bottom end of the cavity through a first limit spring.

[0008] A further improvement is that the second positioning mechanism includes a positioning bolt threaded through the side wall of the fixing foot and a bolt hole opened on the side wall of the support rod, and the bolt holes are evenly distributed on the outer wall of the support rod near the positioning bolt.

[0009] A further improvement is that a T-shaped slider is symmetrically fixed to the bottom end of the placement bottom frame, a T-shaped slide rail adapted to the T-shaped slider is symmetrically opened on the top of the placement plate, and locking mechanisms are provided on the outer walls on both the front and rear sides of the placement bottom frame.

[0010] A further improvement is that the locking mechanism includes a fixing block fixed on the outer wall of the bottom frame and a locking bolt passing through the fixing block, and the bottom end of the locking bolt is threadedly passed through the fixing block and connected to the locking block.

[0011] A further improvement is that the bottom end of the pressure plate is connected to the arc-shaped rubber pressure pad through a symmetrically distributed second limit spring, both ends of the pressure plate are fixed with limit blocks, and the inner walls on both sides of the top frame are provided with limit grooves adapted to the limit blocks.

[0012] The beneficial effects of the utility model are as follows: the utility model includes a support plate, which is connected to a placement plate by rotating at the top of the support plate, and a second positioning mechanism is used to position the placement plate after rotation adjustment, and at the same time, a fixed foot is slidably sleeved on the outside of the support rod at the bottom end of the support plate, and the first positioning mechanism is used to position the support rod after telescopic adjustment, so that the device has the functions of lifting and rotating adjustment at the same time, can meet different limb placement needs, and has high applicability, and by hingedly placing the top frame at the top of the placement bottom frame, the turntable is used to drive the screw rod to rotate downward and drive the pressure plate and the arc-shaped rubber pressure pad to descend, so as to appropriately limit the patient's limbs without compressing the patient's limbs, so that the limbs are effectively limited during surgery and are not easy to detach from the device, and the practicality is high.
