Abstract

The invention relates to a rigidity measuring technology, in particular to a device and method for measuring the rigidity of a flexible driving shaft. According to the device and method of the invention, the problem that there is no device capable of accurately measuring the rigidity of a flexible driving shaft at present is solved. The device for measuring the rigidity of the flexible driving shaft provided by the invention comprises a base, a scale, a transparent baffle, two clamping and pressing strip blocks and two fastening screws, the base comprises a semicircular vertical plate; the end face of the straight section of the semicircular vertical plate faces downwards, and the end face of the straight section of the semicircular vertical plate is provided with a rectangular vertical plate which extends from the end face; a semicircular groove is formed in the front plate surface of the semicircular vertical plate, and the groove wall of the straight section of the semicircular groove faces upwards; a vertical flat hole and two transverse flat holes in bilateral symmetry are formed between the groove wall of the arc-shaped section of the semicircular groove and the end face of the arc-shaped section of the semicircular vertical plate in a penetrating manner; the upper hole walls of the two transverse flat holes are connected into a whole, and the front hole walls of the two transverse flat holes are flush with the rear hole wall of the vertical flat hole. The device and method are suitable for designing and manufacturing the flexible driving shaft.

Description

technical field [0001] The invention relates to stiffness measurement technology, in particular to a stiffness measurement device and method for a flexible drive shaft. Background technique [0002] Minimally invasive interventional therapy is one of the main methods for the treatment of cardiovascular diseases, and it is also used for the treatment of some diseases such as tumors. It is a key development industry in the future medical industry. Power transmission during minimally invasive interventional therapy often requires the use of a flexible drive shaft, whose mechanical properties are directly related to the operability and safety of the treatment. Specifically, if the rigidity of the flexible drive shaft is too large, the flexible drive shaft cannot be bent at a large angle during the treatment process, so that it cannot pass through the curved path to reach the affected area. The bending force acts on the tissue in contact with it, causing damage to the tissue dur...
