EndoSurg Standard System

  • Access: transforaminal and interlaminar
  • Indications: ventral and lateral pathologies, e.g. herniated discs, foraminal stenosis, facet joint cysts, spondylolistheses
  • Field of application: lumbar and thoracic

The EndoSurg Standard System is unintech‘s transforaminal system for full-endoscopic spinal decompression.

The system consists of instruments clearly arranged in a double tray and the endoscope safely stored in a tray, which also has space for the endoscopic light guide.

The set contains all instruments (approx. 22), that are required as standard for endoscopic surgery, e.g. dilators, working tubes, various forceps, chisels, nerve hook, elevator, etc. They are optimally adapted to the procedure and the endoscope in terms of length, diameter and design.

Principal steps of the procedure

Endoscopic pictures show transforaminal approach

Inserting the working tubes U and T
  1. Transforaminal access to the facet joint through serial Dilation
Endoscopic decompression with various instruments
  1. Inserting the working tubes and identifying the intact and untreated bony structures. The outer working tube with teeth is fixed at the bone
Endoscopic view to intervertebral foramen
  1. Foraminotomy with forehead reamer under endoscopic visualization and monitoring
Endoscopic decompression with various instruments
  1. Decompression of the nerves with various instruments
Endoscopic decompression with various instruments
  1. End of the procedure - free nerves

Unique Instruments of the System

The transforaminal approach can be done with the unique Tube-in-Tube technique or traditonal in single tube technique.

  • Single tube technique: with the inner working tube
  • Tube-in-Tube technique: with both working tubes
  • Outer working tube with partial toothing

    partial toothing
  • Working tube, oval window

    (inner working tube)

The outer working tube has teeth for fixation at the facet joint. The inner working tube can be used as retractor.

  • Forehead reamer
    Forehead reamer for endoscopic
    visualized foraminotomy
  • working tube endoscope
    Endoscope inserted in forehead
    reamer and outer working tube

Tube-in-Tube technique: Only with this technique endoscopic visualized and monitored foraminotomy is possible. The inner working tube is replaced by a forehead reamer

EndoSurg Standard Instruments for Decompression
