New spoon retractors aid in the safe removal of soft masses, including brain tumors like gliomas. These surgical tools create space for precise dissection, minimizing tissue damage during procedures.

Area of Science:

  • Neurosurgery
  • Surgical Instrumentation
  • Oncology

Background:

  • Soft mass removal, particularly brain tumors (gliomas, metastatic tumors), presents surgical challenges.
  • Existing retractors may cause tissue damage or insufficient space for dissection, especially with vascular lesions.
  • Haemorrhagic lesions like haemangioblastomas and arteriovenous malformations require delicate handling.

Purpose of the Study:

  • To introduce a novel spoon retractor designed for efficient and safe removal of soft masses.
  • To evaluate the efficacy of the spoon retractor in creating adequate surgical space for dissection.
  • To assess the suitability of the spoon retractor for specific pathologies, including haemorrhagic lesions.

Main Methods:

  • Design and fabrication of spoon retractors with an eggshell-like concave main part (5 mm to 4 cm width) and a flexible shaft.

Related Experiment Videos

  • Application of the spoon retractor during surgical procedures for soft mass removal.
  • Qualitative assessment of the retractor's ability to hold masses, create space, and facilitate dissection.

    • Main Results:

    • The spoon retractor effectively retracts soft masses, creating ample space for dissection from surrounding structures.
    • Demonstrated utility in the en bloc removal of gliomas and metastatic tumors.
    • Facilitated visualization of feeding/draining vessels and enabled removal without laceration or rupture, especially for haemorrhagic lesions.

    Conclusions:

    • The designed spoon retractor is a valuable tool for neurosurgical procedures involving soft mass removal.
    • It offers improved retraction, space creation, and tissue protection compared to conventional methods.
    • Particularly beneficial for managing challenging haemorrhagic lesions, enhancing surgical outcomes.
