It is characterized in that the device does not contact the wound, and the washing of different parts is selected by the operator according to the clinical needs. Different flow rates and different liquid flow shapes may be selected. A clear operative vision can be obtained, and the incidence of surgical infection can be reduced; Bone chips, blood clots and fat particles can be removed sufficiently to reduce the incidence of death due to embolism. 

The product is tested by quality supervision and inspection center, and the performance reaches the standard requirements.  The product is clinical trial in domestic famous hospitals, such as Chinese Academy of Medical Sciences & Peking Union Medical College Hospital, Affiliated Hospital of Anhui Medical University and other domestic famous hospitals. The clinical report shows that the overall performance reaches the level of similar foreign products.

It can effectively prevent infection, inflammation, and reduce wound healing and the like. It is applicable to orthopedics, thoracoabdominal surgery, emergency, gynaecology and so on. And is particularly suitable for cleaning various complex cavities and wall surfaces. The device is characterized in that the device can form a pulse water flow, and the pressure can be adjusted according to the needs, and meanwhile as automatic washing, the device can attract the sewage, reduce the pollution and create a clear view. 

Operating principle: the motor drives the gear to rotate, and the pulse pressure is formed in the piston cavity. Different input power of the motor produces different water pressure, and the flow rate can reach 780ml/min. With different spray heads, different shapes of water flow can be ejected, and can be used for cleaning different parts. 

Can be used for orthopedics: when the joint surgery is performed, the fat particles adhered on the cancellous bone can be removed completely through high-pressure washing, and the fat embolism after operation is reduced. In the total hip or semi-hip replacement surgery of bone cement, the effect of bone trabecula filling in bone cement was increased. Reduces the early loosening of the bone cement fixation prosthesis. Can be used for emergency debridement, can eliminate wound dirt, reduce the occurrence of granuloma, shorten the debridement time and improve the operation efficiency. Can be used for thoracoabdominal surgery, gynaecology, urology and microsurgery, can create a clear field of view in the operation, reduce the visual fatigue of the doctor and improve the operation efficiency. At the same time, the residue after surgery was reduced, and the operation was reduced and issued.

Clinical benefit: The device can perform its intended function in order to remove debris and reduce infection rate (achieved with saline solution).
