Percutaneous Endoscopic Lumbar Discectomy (PELD / TESSYS)

Local Anesthesia 7mm Keyhole · Day-Surgery Spine Endoscopy

国家重点临床专科微创骨科规范术式 / 国械注进 20183042129 · NHC Key Minimally Invasive Spine Technique / Gold Standard for Disc Herniation

Pioneered in China by Prof. Zhou Yue at Xinqiao Hospital, PELD accesses herniated discs through a 7mm keyhole incision under pure local anesthesia via the transforaminal corridor (Kambin's triangle). Under 30x magnification, it removes compressing fragments and radiofrequency-seals the annular tear. Patients communicate pain relief in real time and walk within 2 hours.

Mechanism of Action (MOA)

7mm Transforaminal Natural Corridor + Awake Precision Fragmentectomy

1

Transforaminal Corridor via Kambin's Triangle: Advances directly through the safe anatomical window without bone resection, preserving 100% of native spinal stability.

2

Conscious Local Anesthesia Feedback: Patient remains fully awake and alerts surgeon to nerve proximity, virtually eliminating risk of permanent neurological deficit.

3

30x High-Definition Magnification: Differentiates pearl-white herniated nucleus pulposus from nerve roots and dura, enabling radical fragmentectomy.

4

Low-Temperature Radiofrequency Annuloplasty: 4.0MHz RF energy shrinks and seals the ruptured annular fissure, slashing long-term recurrence rates to <2%.

Patient Profile & Indications

Quantified entry criteria and stages for foreign referral

Lumbar disc herniation (protrusion, extrusion, or sequestered fragments) with severe sciatica failing 4-6 weeks of conservative care.

Young active individuals or athletes demanding zero disruption to spinal stability and motion.

Far-lateral lumbar disc herniation compressing exiting nerve root.

Elderly or medically compromised patients unfit for general anesthesia.

Strict Exclusion Red Lines

• ✕Severe circumferential osseous canal stenosis with heavily ossified ligamentum flavum (requires UBE).
• ✕Degenerative spondylolisthesis >Grade II with severe segmental biomechanical instability.
• ✕Acute irreversible cauda equina syndrome with bilateral paraplegia.
