Devices and methods for presenting and regulating auxiliary information on an image display of a telesurgical system to assist an operator in performing a surgical procedure

Abstract

A method of performing a surgical procedure on a patient is provided. The method typically comprises positioning a surgical work station of a robotically controlled surgical system and a patient on which a surgical procedure is to be performed in close proximity relative to each other, directing a field of view of an image capture device of the surgical work station at a surgical site on the patient, at which site the surgical procedure is to be performed, and introducing at least one robotically controlled surgical instrument on the surgical work station to the surgical site so that an end effector of the surgical instrument is within the field of view of the image capture device. The method typically further comprises displaying an image of the surgical site and the end effector on a display area of an image display at an operator control station of the surgical system. The image display is typically operatively connected to the image capture device so as to display, on the display area, the image of the surgical site and the end effector captured by the image capture device. The method can further include permitting an operator of the surgical system to manipulate a master control at the operator control station whilst viewing the image of the surgical site on the image display, the master control being operatively associated with the surgical instrument thereby to cause the end effector to move in response to manipulation of the master control so as to perform at least part of the surgical procedure on the patient at the surgical site. The method yet further typically comprises operatively linking the image display to a source of selectively accessible auxiliary information related to the surgical procedure to be performed, enabling the operator selectively to access the source of auxiliary information from the operator control station so as to forward the auxiliary information to the image display, causing the auxiliary information to be displayed across the display area of the image display in response to the operator selectively accessing the source of auxiliary information at the operator control station and enabling the operator selectively to move the auxiliary information when displayed on the image display relative to the image of the surgical site displayed on the image display. The master control is typically operatively linked with the source of auxiliary information, enabling the operator selectively to access the source of auxiliary information then including permitting the operator selectively to disassociate the master control from the surgical instrument and to use the master control to access the source of auxiliary information so as to enable the auxiliary information to be displayed on the display area of the image display.

AI Technical Summary

Benefits of technology

This system improves surgical precision, confidence, and safety by enabling intuitive and dexterous manipulation of surgical instruments, reducing recovery times and hospital stays, and increasing the adoption of minimally invasive surgical methods.

Problems solved by technology

However, only a relatively small percentage of surgeries currently use minimally invasive techniques due to limitations of minimally invasive surgical instruments and techniques currently used and the difficulty experienced in performing surgeries using such traditional instruments and techniques.

Thus, expansion in the use of minimally invasive techniques could save millions of hospital days, and consequently millions of dollars annually, in hospital residency costs alone.

There are many disadvantages relating to such traditional minimally invasive surgical (MIS) techniques.

For example, existing MIS instruments deny the surgeon the flexibility of tool placement found in open surgery.

Difficulty is experienced in approaching the surgical site with the instruments through the small incisions.

The length and construction of many endoscopic instruments reduces the surgeon's ability to feel forces exerted by tissues and organs on the end effector of the associated instrument.

Furthermore, coordination of the movement of the end effector of the instrument as viewed in the image on the television monitor with actual end effector movement is particularly difficult, since the movement as perceived in the image normally does not correspond intuitively With the actual end effector movement.

Accordingly, lack of intuitive response to surgical instrument movement input is often experienced.

Such a lack of intuitiveness, dexterity and sensitivity of endoscopic tools has been found to be an impediment to the expansion of the use of minimally invasive surgery.
