Problems solved by technology
At present, many catheters at home and abroad claim to be able to achieve 1:1 torque control, but there are few clear and effective measurement and evaluation methods to verify the torque control of these catheters in the body, which makes it impossible for medical institutions to purchase catheters. Comparing the catheters of various manufacturers is not conducive to the selection of catheters with excellent performance for medical institutions

The invention relates to a torsion control testing device and a testing method, the torsion control testing device is used for testing the torsion control of a conduit, the conduit is provided with a first end and a second end which are opposite to each other, and the torsion control testing device comprises a power mechanism, a resistance applying mechanism and a detection mechanism. The power mechanism is connected with the first end of the conduit and used for driving the conduit to rotate. The resistance applying mechanism is used for applying resistance to the conduit so as to simulate acting force borne by the conduit in a preset object. The detection mechanism is used for detecting first rotation information of the first end of the conduit and second rotation information of the second end of the conduit, and the first rotation information and the second rotation information are used for judging the twisting control performance of the conduit. The device has the advantages that the stress of the conduit in the preset object can be simulated, and the torsion control performance of the conduit can be quantitatively measured.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a torque control test device and a test method. Background technique [0002] Minimally invasive interventional surgery has become the main method of clinical treatment because of its characteristics of no surgery, small trauma, fast recovery and good effect. The process of minimally invasive interventional surgery is: the operator makes a small incision in a certain part of the patient's body, and then sends medical equipment such as a catheter into the blood vessel from the incision and reaches the target position along the blood vessel, and finally performs corresponding treatment at the target position. diagnosis and treatment. During the operation, the operator needs to rotate the catheter to smoothly pass through the tortuous or narrow blood vessels to reach the target position, or to change the position of diagnosis and treatment by rotating the catheter, so the c...
