Embodiment 1

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

[0040] Step 1): take the stone 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 basket 11 through the sheath tube, hold the tail end with the tail end clamp 3, and expose the head end outside the sheath tube 5.

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

[0043] Step 4): Turn on the twist input module 2, and twist the input module 2 at the end of the stone basket 11 to make the stone basket 11 rotate clockwise. When the head turns 360 degrees, the sensor tag 12 on the stone ...

Embodiment 2

[0047] A method for testing the twist control performance of a medical stone-removing mesh basket, the specific steps are as follows:

[0048] Step 1): take the stone basket 11 with a length of 80cm, select a sheath tube 5 with a length of 70cm, and install it on the support column 6.

[0049] Step 2): Pass the stone extraction basket 11 through the sheath tube 5 , the tail end is clamped by the tail end clamp 3 , and the head end is exposed outside the sheath tube 5 .

[0050] Step 3): At the beginning of the experiment, adjust the position of the stone-removing basket 11 so that the sensing tag 12 is close to but not touching one side of the contact rod of the self-stopping device, and then clamp the head of the stone-removing basket 11 with the head end clamp 10. .

[0051] Step 4): Turn on the twist input module 2, twist the input module 2 at the end of the stone basket 11 to make the basket rotate clockwise first, when the head turns 360 degrees, the sensor tag 12 on the...

example 3

[0055] A twist control performance test of a medical stone extraction basket, comprising the following steps:

[0056] Step 1): take the stone basket 11 with a length of 80cm, select a sheath tube 5 with a length of 70cm, and install it on the support column 6.

[0057] Step 2): Turn on the twisting input module 2, set the rotation angle of the end of the stone taking basket 11 to 0-90° and the rotation speed 0.1m / s, and twist the input module 2 to make the stone taking basket 11 start to rotate. The data collector can collect the torsion force curve f at the end of the stone basket 11 in real time 1顺 and the twisting force F at the moment when the twisting ends 1顺 =15.6cN, the data collector on the torsion feedback module 8 at the head end of the stone basket 11 can collect the torsion force curve f at the head end of the stone basket 11 in real time 2顺 and the twisting force F at the moment when the twisting ends 2顺 = 10.3 cN.

[0058] Step 3): Repeat step 2) to rotate t...

Abstract

The invention relates to a torsion control performance testing device and testing method of a medical stone extraction net basket, which is used for testing the torsion angle and torsional force transmission performance of the medical stone extraction net basket, including an active torsion module, a torsion angle transmission test module and a torsional force transmission The active torsion module includes a torsion input module, a tail end clamp, and a first torsion force sensor, which are used to clamp the tail of the medical stone extraction basket, drive the rotation and measure the rotation force and rotation angle; the torsion angle transmission performance test module includes contact Self-stop device and sensor tag, the sensor tag is fixed on the head of the medical stone net basket, and when the sensor tag touches the contact rod of the self-stop device, it triggers the control torsion input module to stop; torsional force transmission performance test The module includes a head end fixture, a second torsion force sensor, and a torsion force feedback module, which are used to clamp the head end of the mesh basket and measure the torsion force. The structure of the device is simple, and the test method is simple and convenient, which provides a new test method for the performance test of the medical stone extraction basket.

Description

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