Global research history
1960
In 1960, the water jet appeared in the United States. Because it has no thermal effect, no particle pollution, and smooth cutting edge, it has quickly been widely used in aerospace, precision manufacturing, and military industries.

1982
In 1982, German professors Puchriston and Barters applied waterjets to surgery for the first time, and found that waterjets could retain more blood vessels, greatly reduce surgical bleeding, and significantly shorten the operation time. Subsequently, waterjets began to be used in many clinical fields abroad.

2002
In 2002, Shanghai Huashan Hospital took the lead in China to use water jets to remove a 30-year-old male patient with a hepatic hemangioma with a diameter of 30 cm and an intratumoral blood of 1000 ml. The operation took only 30 minutes and the healing was good.

In 2021, Hydrajet water knife will be launched on the market as China's first hydrodynamic scalpel with independent intellectual property rights.
open Working Principle
The Hydra Debridement waterjet system uses the tissue separation effect of high-pressure and high-speed water jets and the Venturi effect (a low-pressure vacuum effect is formed near the high-speed liquid/air flow, which produces adsorption and removes inactivated tissue fragments, wound secretions, and bacteria. The biofilm and other biofilms are absorbed and taken away together with the water flow) to remove necrotic and infected tissue;
Integrate surgical debridement and wound washing. Resection, washing and recovery are completed simultaneously. The debridement process is greatly optimized, and a clean wound bed can be quickly prepared.
Three core technologies
Cast the first domestic medical waterjet
01
Miniature aseptic high pressure control technology
The water pressure of sterile normal saline is greatly increased through the ultra-high pressure power pump, and the water pressure of the supersonic jet stream has reached 3 tons per square centimeter. The water molecule stream with huge kinetic energy can realize tissue cutting; the fine water stream of 0.1 mm can be cut from 4mm knife. The head nozzle sprays out, which can accurately separate most of the body tissue

02
Helium sealing process technology
Nano-level sealing technology and flexible connection pipelines achieve safety under ultra-high pressure and pressure resistance, forming a safe and reliable channel for ultra-high-pressure water jets. The peak anti-burst pressure can reach up to 36250PSI (250MPa). With multi-channel structure design and double closed-loop control algorithm, the pressure test accuracy reaches ±5%, and it can output a stable constant current.

03
New organization-specific algorithm based on deep learning
It can identify nerve fibers such as 0.2 mm, can intelligently and accurately identify musculoskeletal, blood vessel, nerve and gland tissue, accurately remove the lesion tissue, automatically take away the cutting debris, and keep the wound surface clear, thereby reducing the difficulty of the operation and allowing various debridement The operation becomes more refined.
open Product advantages
01
Damage reduction
Low damage wound control, precise grinding, cutting and separation.
02
Control infection
Efficiently remove bacteria and bacterial biofilm, simultaneously entrain waste and reduce wound pollution, and keep the wound surface clean.
03
Fast healing
Maximize the preservation of normal wound tissue and promote rapid wound healing.
04
Short procedure
Shorten the operation time, reduce the difficulty of the operation, and reduce the work intensity of the doctor.

Hydrojet waterjet is the "gold standard" for wound debridement surgery. At present, there are really not many good methods for clinical debridement, especially for deep second-degree burns. Traditional debridement tools are difficult to be fine and precise, and the damage is large. Repeated debridement and skin grafting are required; instead, Hydra...

Clinical experiments show that the use of Hydrajet water knife to debride deep second-degree burn wounds can shorten the time of surgical debridement and wound healing, preserve normal tissues to the maximum extent, and improve the quality of healing. Health economics data shows that Hydrojet waterjet can save patient costs, reduce the workload of doctors, i...
