Understanding the Role of Holmium Laser Platforms in Surgical Practice
Holmium laser systems have become a core technology for urology, respiratory medicine, ENT, dermatology, gynecology, and general surgery departments that require precise tissue cutting, vaporization, and urinary stone lithotripsy. Surgical teams evaluating this category typically look for three things: reliable power delivery during long procedures, flexibility to handle both hard-tissue stone fragmentation and soft-tissue ablation, and manufacturing quality backed by recognized certification. The DHL-1 series of Medical Holmium Laser Therapy Machines, manufactured under the DAHUA brand by Longcare Medical, is built around exactly these requirements.
DAHUA’s Holmium Laser Portfolio: Three Power Classes for Different Clinical Needs
Longcare Medical offers the DHL-1 series across three configurations, allowing hospitals to match laser power to case complexity rather than purchasing a single fixed-output device.
DHL-1-D: A Balanced 60W Platform for Multi-Specialty Use
The DHL-1-D (D Model) is positioned as a 60W multi-specialty holmium laser intended for urinary stone lithotripsy and cutting, vaporization, and hemostasis of soft and hard tissues. It serves urology, general surgery, orthopedics, hepatobiliary surgery, gynecology, ENT, and respiratory departments. The unit combines multi-channel laser technology with one to four laser units and a backup laser for surgical continuity, meaning a failure in one channel does not necessarily interrupt an ongoing procedure. It offers a 300μs narrow pulse for fast stone fragmentation and a 600μs wide pulse for soft-tissue cutting, vaporization, and hemostasis, supported by IGBT square-wave technology for uniform energy distribution. Its terminal average output is 60W, with a maximum single pulse energy of 4.0J and maximum operating frequency of 30Hz at a 2100nm wavelength, with series power selection ranging from 20W to 90W. Performance and clinical outcomes have been verified by multiple Class A tertiary hospitals in China, with results reported equal to or better than imported equipment.
DHL-1-F: 100W Output for Demanding Lithotripsy and Soft-Tissue Cases
The DHL-1-F (F-Model) raises terminal average output to the 90W–100W range, supporting a multi-channel laser architecture capable of up to four laser units. It provides the same dual pulse-width logic as the D Model—a 300μs narrow pulse for high peak power lithotripsy and a 600μs wide pulse for soft-tissue cutting, vaporization, and coagulation—while extending fiber compatibility to 200μm, 365μm, 550μm, 800μm, and 1000μm diameters. Maximum single pulse energy reaches 5.0J with a maximum operating frequency of 50Hz. The DHL-1-F has been procured by Chinese hospitals through public tenders, with reported contract prices ranging from 620,000 to 720,000 RMB depending on configuration and tender terms, reflecting real-world institutional adoption.
DHL-1-G: The 120W-Class Platform for High-Burden Procedures and HoLEP
The DHL-1-G (G Model) is the highest-output configuration in the series, built for high-burden lithotripsy, Holmium Laser Enucleation of the Prostate (HoLEP), and broad soft-tissue applications. Its fiber-terminal average output reaches 100W or more, with a maximum output of 120W or more. The platform uses multi-pumping cavity laser coupling output technology and a multi-channel architecture that provides redundancy for uninterrupted procedures, along with dual pulse-width capability, intelligent optical fiber detection with seating verification, and a double-footed foot switch. Maximum single pulse energy is 5.0J, maximum operating frequency is 60Hz, and pulse width is 800μs at the 2100nm wavelength. The DHL-1-G was showcased in a live HoLEP surgery broadcast at the 29th Chinese Urological Association congress and was selected as a 2025 Yangtze River Delta Regional Innovation Product Application Demonstration Case. In Chinese public hospital tenders, award prices have ranged from approximately 970,000 RMB to 1,951,500 RMB, with an average winning price around 1.28 million RMB—figures that indicate sustained demand for this 120W-class platform in institutional procurement.
Shared Engineering Advantages Across the DHL-1 Series
Across all three models, Longcare Medical applies a consistent set of engineering features. Each unit includes intelligent fiber detection with fiber type recommendation and coupling output protection against contamination damage, reducing the risk of fiber-related failures mid-procedure. Each machine is designed for 24-hour continuous operation through a sealed water-cooling system, supporting high case volumes without thermal shutdown. Control is handled through a 10-inch touch-screen interface paired with an expert clinical database, and energy stability is maintained at ±5% across the range. Surgeons can select red or green aiming beams depending on model and preference. These shared characteristics mean that regardless of which power class a hospital selects, the underlying coupling, cooling, and control architecture remains consistent—simplifying staff training across departments that may use more than one DHL-1 variant.
Regulatory Credibility and Clinical Validation
Each DHL-1 model carries China NMPA Class III medical device registration: the DHL-1-G was approved on 2021-12-23 and remains valid until 2026-12-22, while the DHL-1-F and DHL-1-D registrations are valid until 2026-09-13. The DHL-1-F additionally holds EU CE certification, ISO 13485, ISO 9001, and EMC certification. Performance of the DHL-1-G has been validated in Class A tertiary hospitals in China, and the DHL-1-D’s outcomes have similarly been confirmed by multiple tertiary Class A hospitals. Longcare Medical is also listed as a participating unit in drafting China’s national industry standard for medical holmium laser therapy machines, placing the manufacturer directly within the regulatory development process for this device category rather than solely as a downstream compliance follower.
Why Choose Longcare Medical’s Holmium Laser Solutions
For hospitals and surgical centers comparing holmium laser options, the DHL-1 series from Longcare Medical under the DAHUA brand offers a tiered approach: the 60W DHL-1-D for balanced multi-specialty workloads, the 100W DHL-1-F for demanding lithotripsy and soft-tissue cases, and the 120W-class DHL-1-G for high-burden procedures such as HoLEP. All three share the same intelligent fiber protection, continuous water-cooling, and touch-screen clinical database architecture, and all carry NMPA Class III registration alongside documented adoption through Chinese public hospital tenders and clinical validation at tertiary institutions. For procurement teams and surgical departments seeking a holmium laser platform with a clear power-tier structure, transparent regulatory standing, and verified institutional purchase history, the DHL-1 series from Longcare Medical presents a well-documented option backed by direct participation in national industry standard development.
