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:

Related Experiment Videos

  • 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.
