Embodiment 1

[0039] A method for testing the twist control performance of a medical stone extraction basket, the specific steps are as follows:

[0040] Step 1): Take the stone mesh basket 11 with a length of 110 cm, select a sheath tube 5 with a length of 100 cm, and install it on the support column 6 .

[0041] Step 2): Pass the stone extraction basket 11 through the sheath tube, the tail end is clamped by the tail end clamp 3 , and the head end is exposed outside the sheath tube 5 .

[0042] Step 3): At the beginning of the experiment, adjust the position of the stone extraction basket 11 so that the sensor tag 12 is close to but not touching the side of the contact rod of the self-stop device 7, and clamp the head of the stone extraction basket 11 with the head end clamp 10 live.

[0043] Step 4): Turn on the twisting input module 2, and twist the input module 2 at the end of the stone net basket 11 to make the stone net basket 11 rotate clockwise first. When the head turns 360 degree...

Abstract

The invention relates to a device and a method for testing the torsion control performance of a medical calculus removal net basket, which are used for testing the torsion angle and torsion force transmission performance of the medical calculus removal net basket and comprise an active torsion module, a torsion angle transmissibility testing module and a torsion force transmissibility testing module, the active torsion module comprises a torsion input module, a tail end clamp and a first torsion force sensor, and is used for clamping the tail part of the medical calculus removing mesh basket, driving rotation and measuring the rotation force and the rotation angle; the torsion angle transmission performance test module comprises a contact automatic stop device and an induction label, the induction label is fixed on a medical calculus removal net basket wire at the head of the medical calculus removal net basket, and when the induction label touches a contact rod of the contact automatic stop device, the torsion input module is triggered and controlled to stop; and the torsional force transmission performance test module comprises a head end clamp, a second torsional force sensor and a torsional force feedback module and is used for clamping and fixing the head end of the net basket part and testing the torsional force. The device is simple in structure, the testing method is simple and convenient, and a new testing method is provided for performance detection of the medical calculus removing net basket.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a device and method for testing the torsion control performance of a medical stone extraction net basket. Background technique [0002] Calculus is a common and frequently occurring disease worldwide. Although the mortality rate of calculus disease is not high, it seriously affects the quality of life of patients. In order to alleviate the suffering of patients and reduce the risk of surgery, most clinical patients are treated with endoscopic stone extraction. Endoscopic lithotomy is a new minimally invasive technology in recent years. It uses advanced endoscopic technology to directly remove stones from the body through the stone basket. It is especially suitable for the treatment of non-sand-like stones. When endoscopic basket lithotripsy is used, stone removal is generally performed first. If you want to fix or remove the stone, you need to use the stone extraction basket. ...
