Orthopedic quantitative tractor

Abstract

The invention discloses an orthopedic quantitative tractor, which comprises a telescopic traction bar, wherein the telescopic traction bar is formed by sleeving an upper section and a lower section, the top end of the upper section of traction bar is provided with a threaded rod, one end of the threaded rod is connected with an extension spring, and the upper section of bar body and / or the lower section of bar body of the traction bar are connected with a headboard in a detachable mode. When the invention is used, the telescopic traction bar is detachably fixed on the headboard according to the traction needs of patients, the upper section of traction bar is pulled out to a proper position, a free end of the extension spring is connected with the traction position of the patient, and at this time, the threaded rod arranged on the upper section of traction bar is rotated, then the threaded rod pulls the extension spring when sliding in the traction bar so as to make the extension spring produce traction force and drag corresponding parts of the patient.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an orthopedic retractor.
