Toward robot-assisted hard osteolytic lesion treatment using a continuum manipulator
Summary
This study presents a novel actuation unit for a continuum dexterous manipulator (CDM) designed for treating bone degradation. Experiments show the system
Area of Science:
- Medical robotics
- Surgical instrumentation
- Biomedical engineering
Background:
- Osteolysis, or bone degradation, poses a significant clinical challenge requiring precise surgical interventions.
- Existing surgical tools often lack the dexterity needed for complex procedures within bone structures.
- Continuum dexterous manipulators (CDMs) offer enhanced maneuverability for minimally invasive surgery.
Purpose of the Study:
- To design and fabricate an actuation unit for a CDM.
- To integrate the CDM with a positioning robot for precise tool placement.
- To evaluate the feasibility of a novel flexible cutting tool for osteolysis treatment.
Main Methods:
- Development of a specialized actuation unit for CDM control.
- Integration of the CDM with a robotic positioning system.
- Experimental testing of a flexible cutting tool on simulated osteolytic lesions.
Main Results:
- The integrated system demonstrated sufficient dexterity for precise placement of the flexible cutting tool.
- Preliminary experiments confirmed the feasibility of using the novel flexible cutter within the CDM.
- Optimal rotational and sweeping speeds for the cutter were identified, and cutter buckling was investigated.
Conclusions:
- The developed actuation unit and integrated CDM system show promise for treating osteolysis.
- The novel flexible cutting tool is viable for use within a CDM for bone degradation procedures.
- Further research into cutter mechanics and control strategies is warranted.
