Area of Science:

  • Neurosurgery
  • Medical Device Engineering

Background:

  • Stereotactic biopsy procedures require precise instrument fixation.
  • Existing biopsy forceps have limitations in sample size and quantity.
  • Sedan side-biting biopsy cannulas offer advantages but need securement to stereotactic frames.

Observation:

  • An attachment device was developed to connect a Sedan side-biting biopsy cannula to a stereotactic frame.
  • This device addresses the limitations of traditional biopsy cup forceps.
  • The attachment facilitates a straight-line biopsy trajectory.

Findings:

  • The attachment device enables the acquisition of a relatively large amount of multiple specimens.
  • Multiple samples can be obtained along a single biopsy trajectory.
  • The device ensures the side-biting cannula can follow a straight trajectory across various stereotactic frames.

Implications:

  • Improved efficiency and yield in stereotactic biopsy procedures.
  • Potential for enhanced diagnostic accuracy through larger, multiple tissue samples.
  • Increased versatility of the Sedan side-biting biopsy cannula in neurosurgical applications.
