The material of the support member 4 can be a plastic metal material or a plastic material with a supporting effect.

[0037] A drainage pipe 5 is arranged at the lower end of the fluid accumulation bag 1 .

[0038] The present application provides an intraoperative liquid collection device for orthopedic surgery. When in use, the limbs are put on the fluid bag 1 through the openings 2 on both sides of the fluid bag 1, the position of the bag is adjusted so that the surgical area is completely in the bag, and the gap between the side openings 2 and the limbs is sealed by the fastening seal 3 to prevent the liquid from leaking out through the side openings 2. The bag can be unfolded to perform flushing or arthroscopic perfusion. In this way, the device can be directly put on the limbs and fixed before starting flushing. The operation is simple. After the flushing operation is completed, the fastening seal 3 can be loosened to remove the device without affecting the subsequent surgical operation. In addition, medical pulse flushers are often used for flushing and infusion in orthopedic surgery. The flushing water pressure is high and the flow rate is high, which is easy to cause liquid splashing. The side wall of the cavity of the device can block the water droplets and water mist splashed by the flushing to the greatest extent, thereby avoiding the spread of aerosols; and it also reduces the sterile middle sheet or disposable coated middle sheet that is covered to avoid the sterile sheet from being soaked, saving surgical consumables.

[0039] In one possible implementation, see Figure 2 The schematic structural diagram of the side opening being provided with a sterile rope is shown, the fastening seal 3 is a sterile rope 6, and a sterile rope 6 is embedded around each side opening 2 of the fluid collection bag 1.

[0040] By tightening the sterile rope 6 and tying a knot, the side opening 2 is fastened to the limb without any gap, thus preventing the liquid in the cavity from flowing out.

[0041] See also Figure 2 The device is provided with side openings 2 on opposite sides corresponding to the limbs, each side opening 2 is embedded with a sterile rope 6, and after the sterile rope 6 is tightened and overlapped, a gap-free seal is achieved between the side opening and the limb.

When the support rod 82 and the pressing block 9 are fixed by the second bolt 91, the first groove cooperates with the second groove to form a through hole for pressing the support member 4. For details, please refer to Figure 4 The structural schematic diagram of the support rod and the pressing block is shown.

[0050] When the fluid effusion bag 1 is a soft plastic bag, the upper end opening of the fluid effusion bag 1 is kept open by the support member 4, and the upper end of the fluid effusion bag 1 is supported and maintained in a three-dimensional and stiff state by the support members on both sides of the fluid effusion bag 1 to prevent the liquid from spraying outward.

[0051] Optionally, sterile cotton 73 is arranged between the annular extension portion 11 and the limb.

[0052] A portion of the exuded liquid is absorbed by the sterile cotton 73 to keep the external environment of the fluid accumulation bag 1 clean.
