- Replaces traditional colonoscopy as a routine preoperative examination for mixed hemorrhoids, reducing patient discomfort and cost while providing accurate guidance for surgical planning.
- Provides an exploration depth of ≥10 cm from the anal verge, covering approximately 85% of rectal polyps and lesions in the lower sigmoid colon, overcoming the limitations of digital examination and conventional scopes.
- No laxative preparation is required, significantly reducing patient discomfort and shortening examination time.
- Features 1920 × 1080 resolution and 60 fps imaging. The 0° lens adopts a non-contact design with no halo interference.
- Equipped with a medical LED cold light source with illumination ≥3000 Lux and a service life of 60,000 hours. Provides uniform illumination inside the intestine with reduced shadows.
- Supports lens defogging and intestinal cleaning through insufflation and irrigation. Suction reduces intestinal contents. Irrigation flow rate ≥3000 mL/min, suction capacity >5000 mL/min, with adjustable insufflation and suction pressure.
- One-touch image capture, recording, and playback. Customizable report templates enable rapid generation and printing of examination reports.

Used together with an anorectal endoscope to isolate the endoscope from the patient during procedures or examinations, helping prevent cross-contamination.
