Cooperative Surgical Instrument Control Across Variable Access Trajectories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical procedures face challenges in coordinating multiple instruments with variable surgical site access trajectories, particularly when anatomical limitations prevent simultaneous access, and existing imaging systems struggle to recognize concealed structures and convey critical information to medical practitioners.
Innovation Solution
A system comprising two surgical instruments, each with a dedicated endoscope and image sensor, and a controller that acquires images of both instruments to determine their locations relative to each other, enabling coordinated movement and cooperative treatment, even when one instrument is outside the field of view of the other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple surgical instruments are used to operate on tissue from different anatomic spaces, then the ability to treat complex surgical sites is improved, but the difficulty of coordinating and controlling these instruments increases
Solution Approach 1:
A controller serves as an intermediary device that receives control inputs and distributes coordinated commands to multiple surgical instruments. The controller integrates the operation of first and second surgical instruments, allowing them to work cooperatively from different anatomic spaces while maintaining synchronized control through a centralized interface.
Solution Approach 2:
The control system is designed with universal functionality to manage multiple types of surgical instruments simultaneously. The controller can coordinate instruments with different access trajectories and operational modes through a unified control mechanism, enabling versatile treatment of complex surgical sites without requiring separate control systems for each instrument.
2Adaptability or versatility
If surgical instruments approach the surgical site from different anatomic spaces, then access to the target area is improved, but the ability to visualize and track all instruments simultaneously deteriorates
Solution Approach 1:
The controller acts as an intermediary that receives tracking information from multiple sources and synthesizes a unified view of all surgical instruments. By integrating position data from instruments approaching from different anatomic spaces, the controller maintains awareness of all instrument locations and coordinates their movements without requiring direct visual contact between instruments.

AI summary
Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.
