Medical piston pump

The invention provides a medical piston pump, and relates to the technical field of medical instruments. The medical piston pump comprises a pump body, a water inlet pipe and a water outlet pipe, the pump body is provided with a piston cavity, and a piston is arranged in the piston cavity. The head end of the piston cavity communicates with the water inlet pipe and the water outlet pipe; and the water outlet pipe is provided with a water outlet one-way valve. The medical piston pump is limited by the water inlet one-way valve and the water outlet one-way valve, water flow is driven to enter the piston cavity from the water inlet pipe through high-speed piston movement of the piston in the piston cavity, and then flows out of the piston cavity through the water outlet pipe in a high-pressure, continuous and stable mode, and the function of a water jet scalpel can be achieved. The medical piston pump is simple in structure, low in machining and manufacturing difficulty and low in cost. 本发明提供了一种医用活塞泵，涉及医疗器械技术领域。
