Description

Technical Field

[0001] The utility model relates to the technical field of torque elimination, in particular to a structure capable of eliminating the no-load torque of a guide wire torque sensor. Background Art

[0002] A guidewire is a thin, flexible wire or similar material that is used in a variety of applications, especially in medicine and scientific research. The main purpose of a guidewire is to guide other objects through narrow passages or tubes, or to perform internal operations.

[0003] In the medical field, guidewires are often used in procedures such as interventional surgery and angiography. Doctors can insert a guidewire into the human body and then perform treatment or surgical operations along the path of the guidewire. Guidewires can also help doctors guide other devices (such as catheters or stents) to the target location.

[0004] In scientific research, guidewires are also widely used in laboratory operations and instrument design. For example, at the microscopic scale, guidewires can be used to process cells, build microdevices, or manipulate nanoparticles. In materials science, guidewires can also be used in experiments such as tensile testing and circuit connections. The no-load torque of a guidewire torque sensor refers to the torque value generated by the sensor itself without external load or stress. This parameter is usually used to evaluate the sensitivity and error of the sensor. Traditional torque sensors will produce a certain no-load torque error when there is no load, which will cause errors in the measurement results. Therefore, when using a guidewire torque sensor, the no-load torque needs to be eliminated to ensure the accuracy of the measurement results. Utility Model Content

[0005] The utility model provides a structure capable of eliminating the no-load torque of a guide wire torque sensor, thereby solving the above-mentioned technical problems.

[0006] The utility model solves the above-mentioned technical problems as follows:

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a power interface is installed on the fixing plate below the motor.

[0010] The beneficial effect of adopting the above further solution is: by providing power to the motor.

[0011] Furthermore, the motor, the conductive slip ring, the torque sensor and the connecting rod are mounted on the base via a fixing plate.

[0012] The beneficial effect of adopting the above further solution is that it is easy to fix the internal components.

[0013] Furthermore, the power interface and the connecting rod are located outside the shell.

[0014] The beneficial effect of adopting the above further solution is that it is easy to connect the devices.

[0015] Furthermore, the motor is connected to an external power source via a power interface and a wire.

[0016] The beneficial effect of adopting the above further solution is that it is easy to connect the device to the power supply.

[0017] The beneficial effect of the utility model is that the external power supply is connected to the power interface through the wire, and the power interface is connected to the motor. In this way, the motor can obtain the required power supply, and when the motor receives the power supply, it will start to rotate. A conductive slip ring is installed at the output end of the motor. Through the connection of the conductive slip ring, the rotational power of the motor can be transmitted to the next component, and the rotational power of the motor is transmitted to the torque sensor through the conductive slip ring. The torque sensor is a sensor device that can measure torque. When the torque sensor is subjected to torque, it will generate a signal accordingly. The signal of the torque sensor can be transmitted through the connecting rod. A drill clamp is installed on the connecting rod for fixing or connecting other equipment. By reading the signal of the torque sensor, we can accurately measure the torque of the guide wire. When no guide wire passes through, the torque sensor may generate some no-load torque. In order to eliminate the influence of this no-load torque, the motor is designed to rotate in the opposite direction to offset the no-load torque of the torque sensor. By adjusting the reverse rotation speed and strength of the motor, the no-load torque can be effectively eliminated.
