Model 01
TISE-01 Uniportal PLD
The foundation — Full HD at the tip, 130° field of view, integrated working channel.
Product · TISEOne platform.
One platform.
Three models.
TISE is a family of three Full HD single-use spinal endoscopes — one digital imaging core, offered in three shaft sizes with different tip view angles and working lengths for uniportal and biportal approaches.
Quality Highlights
- 01
Single-Use Hygiene
A new sterile scope every case. No reprocessing, no cross-infection risk.
- 02
46 g Ultra-Lightweight Ergonomics
46 g against 214 g conventional — no light cable, no camera head.
- 03
Superior Image Quality & FOV
130° field of view, less distortion, fixed focus, anti-ESU interference.
- 04
Lighting & Color Performance
Dual LED at the tip, all 20 grayscale levels, bleeding stands out.
- 05
Financial Efficiency
No tower investment. No optic scope wearing out over 50–100 cases.
Model 02
TISE-02 Uniportal PSLD
The same imaging core in a wider 10 mm shaft — for PSLD decompression.
Model 03
TISE-03 Biportal UBE
Biportal UBE — a 4.7 mm shaft, instruments through the second portal.

Detachable Handle
Straight or pistol grip —
the surgeon's call
The handle detaches and converts between straight and pistol grip — one scope, either way the surgeon works.
The Console
Every function
on screen
The entire tower, reduced to a portable touchscreen.
- Touchscreen — no separate control units
- Still capture and video, one tap
- Color and image adjustment on screen
- Image and video transmission
On the Wide Screen
One Full HD image,
for the whole room
The same Full HD image at the table and across the room.

Why Surgeons SwitchFive reasons,
Five reasons,
in the surgeon's own order
01 · Real-time
Zero time lag
Motion on screen is motion at the tip — no perceptible delay.
Why it matters
The first question a surgeon asks of any electronic scope: does the screen keep up with my hands? TISE displays what the sensor sees in real time.
02 · Economics
No tower. No hidden costs.
No tower investment — and none of the reusable-scope ledger:
- Use counts no one can track
- Repair cycles between cases
- Failure in the middle of a procedure
With TISE? Open a new one.
03 · Risk
Zero cross-infection
A new sterile scope every case — no residual contamination, no infection-event exposure.
Why it matters
A reprocessed instrument always carries residual contamination risk — and with it, exposure to the litigation that follows an infection event. TISE never touches a second patient.
04 · Handling
46 grams, hours in
No camera head or cables on the wrist. Fatigue doesn't build through an afternoon list.
Why it matters
Endoscopic spine procedures run long, and a conventional scope hangs a camera head and cables off the surgeon's wrist for all of them. TISE weighs 46 grams.
05 · The Failure Mode
Zero fogging.
Structurally.
No optic relay to fog. A sealed sensor at the tip — and every scope is on its first case.
Why it matters
Every endoscopic spine surgeon knows the sequence: irrigation runs through the field while the drill and RF probe heat it. Temperature swings and micro-damage to the optic lens do the rest — the image fogs, and an optic scope that fogs is at the beginning of its end.
- Water, everywhere. Irrigation runs the whole procedure.
- Heat, alongside. Drill and RF in the same narrow field.
- The lens gives way. Thermal swings, micro-damage — moisture gets in.
- Fog — the scope's end. Service life effectively over.
- TISE: structurally zero. No optic relay. Nothing to fog.

Image QualityIndistinguishable from optic —
Indistinguishable from optic —
by surgeons themselves.
TISE doesn't claim a better image — it delivers the one surgeons already trust, captured digitally at the tip, with nothing to fog.
Shown same-patient views — optic scope vs TISE — and asked to pick the digital one, surgeons could rarely tell.

Equal image quality
Judged side by side with optic scopes by the surgeons who use them.
A wider view
130° field of view, against 80° on a conventional optic scope.
Zero fog
A sealed digital sensor — no optic relay for moisture to reach.
No fragile optics
No glass lens train to age, drift, or fail across cases.
