Summary
This study introduces the first 3D-printed hand retractor for pollicization surgery, offering patient-precise customization. The custom tool enhanced surgeon autonomy and demonstrated the potential of rapid prototyping in surgical applications.
Area of Science:
- Biomedical Engineering
- Orthopedic Surgery
- Medical Device Design
Background:
- The pollicization procedure requires specialized surgical instruments.
- Existing retractors may lack patient-specific adaptability.
- Rapid prototyping offers potential for custom surgical tool development.
Purpose of the Study:
- To design, manufacture, and deploy a custom 3D-printed hand retractor for pollicization.
- To evaluate the device's usability and impact on surgical autonomy.
- To showcase the application of 3D printing in creating patient-precise surgical tools.
Main Methods:
- Preoperative radiological imaging for patient-specific anatomical measurements.
- Computer-aided design (CAD) for custom retractor design.
- 3D printing of a sterilizable, radiolucent hand retractor.
- Intraoperative use of the device during a pollicization procedure.
Main Results:
- Successful design, manufacture, and sterilization of the custom 3D-printed retractor.
- The device was effectively used during a pollicization procedure.
- The retractor's radiolucency and interchangeable positions enhanced surgeon autonomy.
- Demonstrated feasibility of on-the-fly, patient-precise tool production using 3D printing.
Conclusions:
- Custom 3D-printed hand retractors are feasible for pollicization surgery.
- This technology enhances surgeon control and adaptability during complex procedures.
- Rapid prototyping enables the creation of patient-specific surgical instruments.
