INSERTABLE ROBOT FOR MINIMALLY INVASIVE SURGERY
20200397516 · 2020-12-24 ·

An insertable robot for minimally invasive surgery includes a tube array having a guide tube housed within a straightening tube. The guide tube includes a curved working end. The guide tube may be axially translated and rotated relative to the straightening tube such that the curved working end is constrained inside the straightening tube, causing the curved working end to achieve a smaller dimension. The tube array is inserted into a working channel on an endoscope, resectoscope or trocar. Once the tube array is inserted, the curved working end of the guide tube is translated forward beyond the distal end of the working channel, allowing the curved working end to return to its pre-formed shape. A surgical tool is inserted through the guide tube for an operation. The straightening tube allows the guide tube curved working end to be temporarily straightened during insertion and removal of the tube array.

SYSTEM AND METHOD FOR GUIDING ULTRASOUND PROBE

A controller and method for imaging an area of interest of a region within an object using a transoesophageal echo (TEE) probe of a TEE ultrasound acquisition system are 5 provided. The controller includes a memory that stores instructions, and a processor that executes the instructions. When executed by the processor, the instructions cause the controller to perform a process including causing a transthoracic echo (TTE) probe of a TTE ultrasound acquisition system to emit an ultrasound beam to a selected area of interest of a region within the object; switching the TEE probe to a listening mode, enabling the 10 TEE probe detect and receive the ultrasound beam emitted by the TTE probe; and causing a robot to steer the TEE probe to an imaging location in the object using the detected TTE ultrasound beam. The TEE probe shows the area of interest using ultrasound images acquired from the imaging location.

The device includes a transporter catheter having a proximal end and a distal end, at least a first balloon located at the distal end, substantially at a tip of the transporter catheter, and at least a second balloon located between the distal end and the proximal end of the transporter catheter. The first balloon is an orienting balloon and the second balloon is an anchor balloon. The transporter catheter may include a single lumen or more than one lumen. The transporter catheter may include a shaft comprising an inner layer and an outer layer, the inner layer may be made of a material more flexible than the material of the outer layer. The outer layer may also include a braided-wire assembly, said braided-wire assembly being formed by braiding a plurality of flat wires or circular wires. The braided-wire assembly may wrap around the inner layer. The transporter catheter may include a shaft that may include a plurality of segments of varying degrees of hardness. The degree of hardness of the segment of the shaft of the transporter catheter located between the first balloon and the second balloon may be less than the degree of hardness of the segment of the shaft between the second balloon and the proximal end of the catheter.
