Abstract

The invention discloses a medical high-pressure pump. The medical high-pressure pump comprises a pump body which is provided with a fluid inlet channel and a fluid outlet channel, a low-pressure pipe base which is arranged inside the fluid inlet channel, a high-pressure pipe base which is arranged inside the fluid outlet channel, a pressure channel which is arranged inside the pump body and connected with the fluid inlet channel and the fluid outlet channel, a piston which is arranged inside the pressure chamber, a transmission rod which drives the piston to move and is connected with a piston opening end which is close to the pressure chamber of the piston. According to the medical high-pressure pump, the pump and a motor transmission structure are separated, the pump and the transmission structure are connected through a standard interface, only the pump body with a simple structure is required to be sterilized before a surgery, medical liquid only flows inside a sterile pipeline of a medical pump after sterilization, infectious risks caused by instruments are reduced, and accurate pressure control of a medical water jet cutter is achieved. The medical high-pressure pump has the advantages of being simple in structure, convenient to operate and safe and reliable, enabling the instruments and pipelines to be rapidly replaced and used and being sterilized.

Description

technical field [0001] The invention relates to the technical field of surgical instruments for minimally invasive surgical cutting, in particular to a medical high-pressure pump. Background technique [0002] Medical water jet is a kind of surgical equipment that uses high-pressure water jet technology to selectively cut human tissue, can accurately protect blood vessels and nerves, and realize minimally invasive surgery. Medical water jet has been widely used in trauma surgery, ENT Surgery, maxillofacial surgery and other surgical operations. The high-pressure pump is one of the core parts of the design of medical water jets. Industrial water jets often use specially-made high-pressure cylinders to supply water to achieve ultra-high pressure performance. The design and manufacture of high-pressure cylinders are relatively complicated, while the pressure of medical water jets is relatively small, and commonly used standard parts such as plunger pumps are often used. Howev...
