Scientific reports·2024

Robotic surgery, particularly radical prostatectomy using the da Vinci Surgical System, is under study. A rare case of a loose surgical instrument bolt during a procedure highlights potential robotic system malfunctions.

Area of Science:

  • * Urology
  • * Surgical Robotics
  • * Medical Device Engineering

Background:

  • * Robotic surgery has gained traction in various medical fields, including urology.
  • * Radical prostatectomy is a common procedure where robotic assistance is increasingly utilized.
  • * The da Vinci Surgical System is a leading platform for robotic-assisted surgeries.

Observation:

  • * A case report details a radical prostatectomy performed with the da Vinci Surgical System, utilizing its fourth arm.
  • * During the procedure, a bolt from the Prograsper forceps unexpectedly loosened.
  • * This malfunction diminished the instrument's functionality and complicated its removal.

Findings:

  • * This is the first reported instance of a Prograsper forceps bolt loosening during robotic prostatectomy.
