A knee joint effusion auxiliary extraction device for orthopedics

Abstract

The application belongs to the technical field of medical auxiliary instruments, and discloses a knee joint effusion auxiliary extraction device for orthopedics, which comprises a base plate and an extraction assembly. The base plate is connected with a seat, a lower leg abutting assembly and a foot rest. The seat is connected with a thigh clamping assembly. The horizontal central planes of the thigh clamping assembly, the lower leg abutting assembly and the foot rest coincide with each other. The lower leg abutting assembly is connected with the base plate through a control assembly. The lower leg abutting assembly is also connected with a positioning assembly and a flow rate control assembly. The extraction assembly comprises a puncture needle and an extraction device. The foot rest is used for placing feet. The thigh clamping assembly is used for clamping and fixing thighs. The lower leg abutting assembly is used for abutting lower legs. The positioning assembly is used for controlling the puncture point and the puncture angle of the extraction assembly. The flow rate control assembly is used for controlling the extraction speed of effusion. The extraction effect / efficiency and safety of effusion are high.
