Solution Overview

Problem

Existing medical instruments and systems lack the ability to perform minimally invasive procedures with enhanced imaging and guidance, requiring awkward arm motions and are not easily controllable by a single user.

Innovation Solution

A robotically-enabled medical system with a cart-based or table-based configuration that includes robotic arms and a tower for supporting medical instruments, providing enhanced imaging and guidance, allowing single-user control, and enabling procedures like bronchoscopy, ureteroscopy, and laparoscopy with improved ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional manual surgical instruments are used, then the procedure can be performed with simple equipment, but the operator requires awkward arm motions and cannot be easily controlled by a single user

Engineering Contradiction:
Improveease of controlVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical manipulation with a robotic system that uses servo motors and master controllers to actuate surgical instruments. The robotic arm manipulates the uterine manipulator and colpotomy cup through automated mechanical systems, eliminating the need for awkward arm motions while enabling precise control by a single operator through the master controller interface.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If traditional surgical approaches are used, then the setup is simple, but multiple users are required and arm motions are awkward

Engineering Contradiction:
Improvesingle-user control capabilityVSAvoidrobotic system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robotic system is designed to perform multiple surgical functions through a single integrated platform. The master controller can operate various surgical instruments including the uterine manipulator, colpotomy cup, and other surgical tools, allowing one operator to perform tasks that traditionally required multiple users. The system provides versatile control capabilities for different surgical procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Loss of information

If manual manipulation of uterine manipulator is used, then the system is simple, but imaging and guidance are not enhanced

Engineering Contradiction:
Improveimaging and guidance qualityVSAvoidrobotic system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The robotic system incorporates imaging and guidance systems that provide real-time feedback to the operator. The master controller receives information from imaging systems and uses this feedback to guide the robotic arm's movements, enhancing the operator's ability to visualize and navigate surgical anatomy. This feedback loop improves imaging utilization and guidance quality compared to manual manipulation.

Inventive Principle:
Principle #23Feedback

AI summary

An apparatus includes a base portion, a shaft, a colpotomy cup, and a colpotomy cup actuation assembly. The colpotomy cup is slidably attached along a length of the shaft and is configured to acuate along the shaft between a proximal position and a distal position. The a colpotomy cup actuation assembly is configured to drive the colpotomy cup between a proximal position and a distal position. The colpotomy cup actuation assembly includes an actuating assembly configured to operatively couple with a drive output of a robotic arm. The colpotomy cup actuation assembly further includes an elongated member extending distally from the actuating assembly and terminating into a distal end fixed relative to the colpotomy cup. The actuating assembly is configured to drive movement of the elongated member relative to the elongated shaft to thereby drive movement of the colpotomy cup between the proximal position and the distal position.
