Description

Technical Field

[0001] The present application relates to the technical field of traction devices, and in particular to an orthopedic traction device. Background Art

[0002] Related technology (Announcement No.: CN117752483B) discloses an orthopedic traction bed, comprising a bed frame and a traction pillow. Symmetrical through-slots are defined in the bed frame, and the traction pillow is positioned between them. A tilting mechanism rotates within the slots, and a clamping ring is fixedly connected to the tilting mechanism. A telescopic cylinder is fixedly connected to the bottom of the bed frame near the traction pillow. A traction block is fixedly connected to the telescopic output end of the cylinder, and a traction belt is fixedly connected to the traction block.

[0003] In the process of implementing the technical solution of the present disclosure, it was found that the above technical solution has at least the following problems:

[0004] This orthopedic traction bed features two clamping rings for securing the patient's shoulders, and a traction belt for pulling the patient's neck. Once the patient's shoulders are secured by the two clamps, the traction belt is driven by a telescopic cylinder to stretch the patient's neck.
