A novel endoscopic forceps simplifies third ventriculostomy by enabling both floor perforation and enlargement. This technique streamlines the procedure, reducing the need for multiple instruments during endoscopic third ventriculostomy.

Area of Science:

  • Neurosurgery
  • Medical Devices
  • Endoscopic Surgery

Background:

  • Third ventriculostomy is an established endoscopic procedure for cerebrospinal fluid diversion.
  • Conventional techniques often require multiple instruments for floor perforation and enlargement.

Purpose of the Study:

  • To introduce a novel, sterilizable modified forceps for endoscopic third ventriculostomy.
  • To evaluate the efficacy and simplicity of this new instrument in creating ventriculostomies.

Main Methods:

  • A modified forceps with a thin tip for perforation and indented jaws for enlargement was designed.
  • The instrument was used to create an approximately 4-mm opening in the floor of the third ventricle.
  • The procedure involved gentle pressure and slow opening of the forceps to engage the edges of the aperture.

Main Results:

  • The modified forceps successfully created the opening and enlarged the ventriculostomy in all 10 consecutive patients.
  • The instrument's design prevented slippage and protected basal cistern vessels due to smooth inner jaw surfaces.
  • The procedure was noted to be simple, quick, and effective.

Conclusions:

  • The novel forceps offer a simplified, single-instrument solution for endoscopic third ventriculostomy.
  • This device enhances surgical efficiency and potentially reduces costs by eliminating the need for additional disposable instruments.
  • The technique is safe and effective for creating ventriculostomies.
