In medical technology, a torquer is a guide and handling aid for guide wires . A guide wire is a very thin wire, often less than half a millimeter in diameter, that is inserted into a patient's hollow vessels by a doctor . A catheter for diagnosis or therapy, for example, should later be inserted along this wire .

Since such wires are very thin, it is very difficult for the doctor, who usually also wears surgical gloves, to handle them. The Torquer, which is a few millimeters in diameter and a few centimeters in length, helps with this. The guidewire is in a guide groove is introduced and clamped via a clamping means. This can be solved if more wire is needed and nowadays can usually be operated with one hand.

The doctor, who usually observes the current position of the guide wire in the body in real time , for example by means of a tomographic image , can now push the clamped wire forwards or backwards and twist it with the help of the torquer.

The torquer takes its name from the Latin word torquere (to twist). Thus, other tools for generating torque are also referred to as torquers.
