Litho Surgical Laser System

30W – 35W Holmium system for Lithotripsy

Litho surgical unit is based on Holmium (Ho:YAG) laser with emission at two (2100nm) micron wavelength. This wavelength is highly absorbed by water and biological tissue. The Litho automatically adjusts the correct pulse duration depending on the operating mode and sets the values for energy and repetition rate.

When it is operating in a short pulse emission mode, it is highly effective in the fragmentation of calculi and the hard tissue ablation. In long pulse emission, it is highly effective in cutting soft tissue providing excellent hemostasis and coagulation with minimal damages of surrounding tissue, due to its low penetration depth. Because of its high water absorption, the application in a hydrous solution environment is highly safe.

  • Lithotripsy – Dusting Effect · Lithotripsy – Hard Stone


The Litho laser system has state-of-the-art technical specifications, which represent a gold standard in the surgical market:


Pulse energy: it is possible to set up to 5 J per pulse. The pulse energy is related to the fragmentation efficacy. It is ideal for hard stone treatments.


Repetition rate: the maximum repetition rate is 30 Hz. By using the high repetition rate and low pulse energy, a fine fragmentation is secured. The DUSTING effect function assures the effective dusting even at high repetition rates.


Pulse duration: the unit provides a broad range of pulse durations. Due to this feature, the system could select the most suitable modality of preset parameters in the application menu (HARD STONE-DUSTING-ABLATION-COAGULATION).


The maximum effectiveness in ablation and fragmentation is assured also when using flexible ureteroscopes.

Litho Surgical Laser System

The Device at a Glance

Litho device is a Holmium (2.1 μm) surgical laser offering a wide selection of settings for the treatment of stones and soft tissue surgery, together with high versatility, cost-effectiveness and ease of use.

Its radiation is strongly absorbed by water, resulting in effective hemostasis and limited depth of penetration (0.3-0.4mm).

Apart from urology treatments, this device can be used in the resection and ablation of different soft tissues.

The compact tower design simplifies its transportation and storage, easing its use in different hospital wards.

Dusting Effect

Stone retropulsion and migration often prolong lithotripsy treatment, in particular with high pulse energy.

Litho device is equipped with the Dusting Effect mode, taking advantage of the extremely long pulse width to perform a smoother ablation of stone, limiting retropulsion without affecting fragmentation efficiency.

The obtained fine dust obviates the need for retrieval of fragments by basket.

The setting is intended for calculi, especially the renal ones, where the dusting effect lithotripsy technique could eliminate the need for basket extraction and that way reducing the total time of the procedure.

Due to the extended pulse properties, the specific settings of repetition rate and pulse energies, characteristic for dusting lithotripsy, assure more stable position of stone.

Lithotripsy applications

Wide range of Applications

Its limited depth of penetration (0.3-0.4mm), together with the incision and hemostasis properties of this radiation, enables a large variety of surgical treatments.

Apart from stone fragmentation (urolithiasis, salivary stones, gallstones) and urology treatments (e.g. strictures, carcinoma resection), Litho device can perform effective soft tissue surgery in other medical specialties, including General Surgery, Arthroscopy and ENT.


Through the RFID fiber recognition system, the connected fibers are automatically detected. The laser immediately sets up adequate working parameters.

Smart Interface

Interactive interface with intuitive shortcut to the main function. Smart selection of output settings depending on the operative mode. Wide color touch screen.

Double Footswitch

The double footswitch with front connector allows operator to control the Ready/Standby status directly from the footswitch without the need of assistance in operation by touchscreen.

Double Foot Switch

Wide range of Fibers

A great versatility in applications requires a wide range of delivery probes. For this reason, Litho laser is compatible with different fiber diameters (200-1000µm) and types.

Apart from standard fibers, our portfolio includes ball tip fibers (for easier insertion into already bent scope), performance probes (to deliver even higher output power).
