Hydraulic propelling device

A hydraulic propelling device is composed of a handle, a spiral piston rod, a hydraulic pressurizing barrel, a pressurizing piston, O-shaped sealing rings, a digital display pressure gage, an upper quick-mounted external connector, an upper quick-mounted internal connector, a flexible pipe, an injection piston, a high-viscosity fluid syringe, a sealing pad, a spiral end cover, a lower quick-mounted external connector, a lower quick-mounted internal connector, a quick-mounted rear end cover, a handlebar and a rear end cover plate. The hydraulic propelling device is characterized in that two O-shaped sealing rings (4) are arranged on the pressurizing piston (3), the digital display pressure gage (5) is in threaded connection on the hydraulic pressurizing barrel (2) to enable an operator to judge control on injection quantity of the high-viscosity fluid according to displayed pressure values. Thus, personal difference of different patients can be met, operability of surgery is improved, and surgery risk is reduc
