Description

Technical Field

[0001] The utility model relates to the technical field of reduction clamps, in particular to an adjustable calcaneal reduction clamp. Background Art

[0002] Reduction forceps are a kind of medical device, which are often used in the reduction process of fractures or joint dislocations to help doctors restore bones or joints to their normal position. Reduction forceps are usually composed of two arms and movable connecting parts. By adjusting the position and angle of the forceps, doctors can apply force to reduce bones or joints. Among the reduction forceps, an adjustable calcaneal reduction forceps is often used.

[0003] When using the existing calcaneal reduction forceps, the reduction forceps are needed to temporarily fix the initially reduced bones. However, the existing calcaneal reduction forceps do not have a positioning function when in use, and the doctor needs to maintain pressure on the forceps to position, which is very troublesome and the doctor cannot free his hands to do other things.
