Abstract

The invention discloses a surgical mechanical arm joint hydraulic locking power generator. The power generator comprises a supporting mechanism, a transmission mechanism, a thrust mechanism in electric control and a force-generating mechanism, wherein the thrust mechanism contains a lead screw housing; the lead screw housing is fixedly linked with a connection cover of the transmission mechanism, the center axle of the thrust mechanism is vertical to the axle of the transmission mechanism; the force-generating mechanism and the transmission mechanism both have symmetric structures, share the same axle and are fixedly locked through loop nuts arranged on the periphery of the force-generating mechanism, and the supporting mechanism is fixedly linked with the thrust mechanism. The invention provides a hydraulic power source of joint locking to ensure that the mechanical arm can be used as the puncture positioning device and supporting device for the surgery; and the power generator of the invention has the advantages of small volume, compact structure, light weight, large locking torque, convenient operation and maintenance, long service life and the like, and is applicable to joint positioning of the mechanical arm used in the minimally invasive sugery of neurosurgery, chest surgery, orthopeadic surgery, stomatology and the like.

Description

technical field [0001] The invention relates to a hydraulic locking mechanism, in particular to a joint hydraulic locking power mechanism applied to a surgical manipulator, belonging to a hydraulic drive device for joint locking of the surgical manipulator. Background technique [0002] In recent years, with the rapid development of computer and image processing technology, surgery and surgical technology, and service robot technology, as well as the improvement of public health care awareness, minimally invasive surgical robot technology for the purpose of improving surgical quality and efficiency has become an important topic at home and abroad. One of the frontier research hotspots that scholars pay attention to, it has become an important industry direction that many enterprises pay attention to. At present, for the mechanical arm for surgical puncture positioning, the joints are locked by motors or electromagnetic brakes, which are realized by the position servo or hold...
