Dual-Control Surgical Instrument for Accessory Hand-Off Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Minimally invasive surgical procedures face inefficiencies due to the need for separate manual and teleoperated instruments for introducing surgical implements like sutures, gauze, sponges, clamps, and needles, requiring time-consuming hand-off procedures that compromise safety and accuracy.
Innovation Solution
A dual-control surgical instrument with a dual-control instrument activation system that allows manual and teleoperational control of end effectors, enabling seamless integration of surgical accessories through a prearranged gripping configuration and controlled movement within the surgical site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate manual and teleoperated instruments are used for introducing surgical implements, then safety and accuracy can be maintained, but procedural efficiency deteriorates due to time-consuming hand-off procedures
Solution Approach 1:
The patent merges manual and teleoperated control into a single dual-control surgical instrument. The instrument includes a dual-control activation system that can be operated either manually or teleoperated, eliminating the need for separate instruments and hand-off procedures. This integration maintains safety and accuracy while significantly improving procedural efficiency.
Solution Approach 2:
The surgical instrument is designed with multi-functionality to perform both manual and teleoperated operations. The dual-control activation system allows the same instrument to serve multiple purposes: manual operation for introducing surgical implements and teleoperated operation for precise control during procedures, making it a universal tool that replaces both separate instrument types.
2Adaptability or versatility
If manual instrument hand-off procedures are used, then flexibility in introducing surgical accessories is maintained, but time consumption increases
Solution Approach 1:
The dual-control activation system is pre-configured to maintain the surgical instrument in a prearranged gripping configuration, ready for immediate teleoperated use. The system prepares the instrument in advance so that when teleoperated control is engaged, the instrument is already positioned and configured, eliminating time-consuming adjustments and hand-off procedures while maintaining flexibility for different surgical accessories.
3Device complexity
If a single instrument type is used for all surgical operations, then device complexity is reduced, but adaptability for different surgical tasks deteriorates
Solution Approach 1:
The surgical instrument incorporates a dynamic dual-control activation system that can adapt its operation mode based on the surgical task requirements. The system can switch between manual and teleoperated control modes, allowing a single instrument type to handle different surgical tasks dynamically. This dynamic adaptability maintains versatility while avoiding the complexity of having multiple specialized instrument types.

AI summary
A method comprises receiving a surgical instrument into engagement with a grip actuator of a teleoperational activation system. The surgical instrument includes movable jaws, and the surgical instrument is received in a prearranged gripping configuration with the jaws gripping a surgical accessory. The method includes generating a first control signal for manipulating the surgical instrument while maintaining the surgical instrument in the prearranged gripping configuration. The method further includes generating a second control signal for manipulating the surgical instrument to move from the prearranged gripping configuration to a second configuration.
