Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to an angle-adjustable medical debridement water jet scalpel.

Background

The medical water knife is a new type cutting process using water as medium, and is characterized by that the specially-treated water is injected into a high-pressure water pressurizing system to make the water be quickly pressurized, then the high-pressure water is passed through a nozzle with small diameter, and jetted to cut tissue. The traditional scalpel has the following defects: firstly, although the tissue is cut off quickly, the necrotic tissue cannot be removed in a fine and controllable manner, and the tissue cannot be cut by one knife and cannot be cut for multiple times because the necrotic tissue and the active tissue are contacted with the wound; secondly, the special part is limited and needs to be dilated when necessary; third, multiple resections of tissue can result in major bleeding; fourthly, the wound is not suitable for the debridement of the ischemic ulcer; therefore, a medical water jet is needed.

The prior art has the following problems: the water jet scalpel cannot be adjusted, so that a great deal of inconvenience is brought to debridement, the use of doctors is influenced, and even secondary injury is caused to patients.
