AI Technical Summary

Benefits of technology

The present invention is a surgical controlling system that uses a touchscreen, body-ported sensors, and a movement detection system to direct surgical tools in a laparoscopic surgery. The system can also use real-time images from an endoscope or other surgical tools. The system can also store predefined routes for the surgical tools and detect and prevent collisions between the tools. The technical effects of the invention include improved precision and efficiency in surgical procedures and reduced risk of injury to the patient.

Problems solved by technology

The equipment is often expensive and is not available in all hospitals.
However, these improved technologies still fail to address another complicating interface aspect of laparoscopic surgery, in that the surgeon must still keep his attention on the process of moving until the movement is complete.

System with Collision Avoidance System

[0470]One embodiment of such a rule-based system will comprise the following set of commands:

[0471]Detection (denoted by Gd):

Gd1 Tool location detection function

Gd2 Organ (e.g. Liver) detection function

Gd3 Movement (vector) calculation and estimation function

Gd4 Collision probability detection function

[0472]Tool Instructions (denoted Gt):

Gt1 Move according to manual command

Gt2 Stop movement

[0473]The scenario—manual move command by the surgeon:

[0474]Locations Gd1(t) and Gd2(t) are calculated in real time at each time step (from an image or location marker).

[0475]Tool movement vector Gd3(t) is calculated from Gd1(t) as the difference between the current location and at least one previous location (probably also taking into account previous movement vectors).

[0476]The probability of collision—Gd4(t)—is calculated, for example, from the difference between location Gd1 and location Gd2 (the smaller the distance, the closer the proximity and the highe...

System with Soft Control—Fast Movement when Nothing is Nearby, Slow Movement when Something is Close

[0481]One embodiment of such rule-based system comprises the following set of commands:

[0482]Detection (denoted by Gd):

Main Tool location detection function (denoted by GdM);

Gd-tool1-K—Tool location detection function;

Gd-organ2-L—Organ (e.g. Liver) detection function;

Gd3 Main Tool Movement (vector) calculation and estimation function;

Gd4 Proximity probability detection function;

[0483]Tool Instructions (denoted Gt):

Gt1 Movement vector (direction and speed) according to manual command

[0484]The scenario—manual move command by the surgeon:

[0485]Locations GdM(t), Gd-tool1-K(t) and Gd-organ2-L(t) are calculated in real time at each time step (from image or location marker).

[0486]Main Tool Movement Vector Gd3(t) is calculated per GdM (t) as the difference between the current location and at least one previous location (probably also taking into account previous movement vectors)

System with No-Fly Rule / Function

[0489]In reference to FIG. 3, which shows, in a non-limiting manner, an embodiment of a tracking system with no-fly rule. The system tracks a tool 310 with respect to a no-fly zone (460), in order to determine whether the tool will enter the no-fly zone (460) within the next time step. In this example, the no-fly zone 460 surrounds the liver.

[0490]FIGS. 3a and 3b show how the behavior of the system depends on the location of the tool tip with respect to the no-fly zone, while FIGS. 3c and 3d show how movement of the tool affects the behavior.

[0491]In FIG. 3a, the tool 310 is outside the no-fly zone rule / function 460 and no movement of the tool is commanded. In FIG. 3b, the tool 310 is inside the no-fly zone 460.

[0492]The no-fly zone rule / function performs as follows:

[0493]In the embodiment illustrated, a movement 350 is commanded to move the tool 310 away from the no-fly zone 460. In other embodiments, the system prevents movement further into the no-...

Abstract

A surgical controlling system, comprising: at least one surgical tool configured to be inserted into a surgical environment of a human body; at least one location estimating means configured for real-time localization of the 3D spatial position of said at least one surgical tool at any given time t; at least one movement detection means communicable with a movement's database and with said location estimating means; a controller having a processing means communicable with a controller's database; said controller's database is in communication with said movement detection means; and at least one display configured to real time provide an image of at least a portion of said surgical environment; wherein said controller is configured to direct said surgical tool to said location via said instructions provided by said controller; further wherein said location is real time updated on said display as said at least one surgical tool is moved.

Description

FIELD OF THE INVENTION[0001]The present invention generally pertains to a system and method for directing a laparoscopic system by means of at least one of a touchscreen, body portion of the user movement and eye movement, sound being made by the user.BACKGROUND OF THE INVENTION[0002]In laparoscopic surgery, the surgeon performs the operation through small holes using long instruments and observing the internal anatomy with an endoscope camera.[0003]Laparoscopic surgery is becoming increasingly popular with patients because the scars are smaller and their period of recovery is shorter. Laparoscopic surgery requires special training for the surgeon and the theatre nursing staff. The equipment is often expensive and is not available in all hospitals.[0004]During laparoscopic surgery, it is often required to shift the spatial placement of the endoscope in order to present the surgeon with an optimal view. Conventional laparoscopic surgery makes use of either human assistants that manua...
