Six axis F/T sensors applied in surgery

In traditional open surgery, doctors can perceive force feedback to determine the force applied to tissues and organs. This interactive information allows doctors to perform more precise operations on patient tissues and organs. For example: in the exploration operation, the doctor can touch the tumor/lumps or calcified cardiovascular system, force feedback can help the doctor quickly identify the diseased tissues and organs, and avoid damage to the normal tissues and organs; in the process of blunt cutting When sewing and suturing, force feedback is very important to avoid damage to normal tissues and vital organs during the operation.

With the continuous development of surgical technology, minimally invasive surgery and robot-assisted surgery have emerged. These new surgical methods, for doctors, through 3D vision technology, can allow doctors to observe the patient's ward more carefully, help doctors formulate surgical plans before surgery and perform precise operations on the diseased area during surgery. At the same time, this method The wounds caused to patients are smaller, which can reduce the occurrence of perioperative sequelae and complications, and allow patients to recover faster.

But at the same time, we also found that the current minimally invasive surgical robots cannot provide force feedback, resulting in a complete loss of the doctor's sense of touch during surgery. Although doctors can adapt to this type of surgery that lacks force feedback through continuous practice, if the mechanical arm fails, the mechanical arm lacking force feedback cannot be stopped and reset immediately, which may cause injury to the patient or even Threat to life safety-medical accidents caused by intraoperative failures of related surgical robots occasionally occur, and from a technical point of view, the probability of robot failures always exists. What we need is a solution to the failure.

If the minimally invasive robot has a force feedback function, it is required to install a six-dimensional force sensor at the end of the surgical manipulator, and the size, weight, and accuracy of the sensor are extremely demanding. At present, this direction is still in the research stage in China. . As the domestic leading brand of six-dimensional force sensors, Hyberson is committed to producing first-class sensor products, and will continue to maintain attention to this frontier field and explore the boundaries of technology and more possibilities.
