Leisegang® by CooperSurgical

For more than six decades, Leisegang® has been recognized as a global leader in colposcope design, valued for German precision engineering, optical clarity, and long-term reliability in women’s health settings.

The Leisegang OptiK® series combines hand-finished German optics with high-intensity white LED illumination to support detailed visualization of cellular and vascular changes. Convergent optical beam paths, multi-step magnification, and a 300 mm working distance are designed to deliver sharp, three-dimensional images with excellent contrast while helping clinicians work comfortably, even during longer examinations.

German Engineered for Precision

For cervical cryosurgery, the Leisegang® LM-900 Cryosurgery System extends this focus on precision from diagnosis to treatment. The LM-900 is a high-performance, cost-conscious solution for busy OB/GYN, colposcopy, and family planning practices, providing an efficient, reproducible freeze for cervical cryotherapy and the controlled destruction of defined areas of benign or pre-malignant lesions, in accordance with its intended use.

Engineered for continuous use, the LM-900 features excellent thermal conductivity and an easy-to-read calibrated pressure gauge to support accurate freeze temperatures. An insulated probe barrel, high-strength gas lines, and a solid brass manifold help enhance safety, while the lightweight handpiece, comfort-shaped handle, and compact console are designed to reduce operator fatigue and save space. A wide choice of handcrafted, coin-silver cryotips—available in general purpose, exocervical, exo/endocervical, and other specialty designs—allows clinicians to match probe geometry to lesion type and anatomical location.

Frequently Asked Questions about Leisegang® by CooperSurgical

What is the Leisegang OptiK® colposcope series?

The Leisegang OptiK colposcope series is a family of German-engineered colposcopes designed for detailed visualization of the cervix, vagina, vulva, and anogenital areas. The systems pair hand-polished optics with high-intensity LED illumination to provide sharp, three-dimensional images that support screening, diagnosis, and documentation in gynecologic care.

How does LED illumination improve visualization during colposcopy?

Leisegang colposcopes use bright, color-stable white LEDs with high light intensity at a 300 mm working distance, helping to enh ance contrast and visibility of fine vascular patterns and epithelial changes. LED technology also offers long service life and low power consumption, reducing the need for lamp replacement and associated downtime.

What is the Leisegang® LM-900 Cryosurgery System used for?

The Leisegang LM-900 is a cryosurgery system intended for cervical cryotherapy and for the controlled destruction of defined areas of benign or pre-malignant lesions, as described in its instructions for use. It is typically used in OB/GYN and family planning practices that perform outpatient cryotherapy procedures.

What features of the LM-900 help support accurate and consistent freeze performance?

The LM-900 incorporates excellent thermal conductivity for continuous usage, along with a calibrated, easy-to-read pressure gauge that helps clinicians achieve consistent freeze parameters. Insulated probe barrels and robust gas lines are designed to maintain performance while contributing to patient and operator safety.

Which cryogenic gases can be used with the LM-900 Cryosurgery System?

The LM-900 system can be ordered with a 20 lb gas cylinder configured for either nitrous oxide (N₂O) or carbon dioxide (CO₂), depending on practice preference and local availability. The selection of gas type should follow institutional protocols and applicable regulations.

What probe options are available for the LM-900?

Leisegang offers a wide range of handcrafted, double-bonded, coin-silver cryotip probes for the LM-900, including general-purpose, exocervical, exo/endocervical, and specialty tips for various lesion sizes and locations. Recommended OB/GYN tips include models such as 50105, 50108, 50109, and 50110, allowing clinicians to tailor cryotherapy to the clinical scenario.

Is the LM-900 suitable for high-volume practices?

Yes. The LM-900 is designed for busy clinics, with a lightweight handpiece, comfort-shaped handle, and finger-trigger control that help reduce fatigue during repeated procedures. A compact, molded console and integrated tip holder support efficient workflow and convenient storage in high-volume environments.
