Summary
Developed thoracoscopic needle biopsy forceps for diagnosing lung tumors during surgery. This minimally invasive technique is economic and avoids unnecessary lung resections, improving patient outcomes and reducing healthcare costs.
Area of Science:
- Thoracic Surgery
- Surgical Oncology
- Diagnostic Procedures
Context:
- Preoperative diagnosis of lung tumors is often uncertain, necessitating intraoperative assessment.
- Traditional thoracoscopic wedge resection followed by lobectomy incurs significant economic loss due to disposable stapler cartridge waste.
- Thoracoscopic needle biopsy offers an economic alternative but presents technical challenges and risks of damaging vital structures.
Purpose:
- To develop novel forceps for thoracoscopic needle biopsy to facilitate accurate and safe tissue sampling during surgery.
- To create a minimally invasive diagnostic tool that overcomes the limitations of existing methods.
- To improve the diagnostic yield and safety profile of intraoperative lung tumor biopsies.
Summary:
- Modified endoscopic grasping forceps with a needle guide and safety features for thoracoscopic needle biopsy.
- Developed three sizes of forceps (small, middle, large) to accommodate various tumor sizes.
- Successfully diagnosed 35 out of 43 lung tumors with no complications, demonstrating the efficacy and safety of the developed forceps.
Impact:
- Reduces economic loss associated with disposable surgical materials.
- Minimizes the need for extensive lung resections when malignancy is suspected but not confirmed preoperatively.
- Provides a safe, easy, and economic method for intraoperative diagnosis of lung tumors, contributing to medical cost-effectiveness.
