specific Embodiment

[0024] Such as figure 1 As shown, including the hydraulic source section, the oil injection module and the isolation module.

[0025] The hydraulic source part includes a hydraulic source housing 1, a hydraulic source piston 17, and a first joint shaft 2 that is in clearance fit with the hydraulic source housing, and a hydraulic oil circuit communicated with the first joint shaft 2 and the hydraulic source housing 1 is opened. 16. Through the up and down movement of the hydraulic source piston 17, the pressure of the hydraulic oil circuit 16 can be adjusted to realize the locking and releasing of the joints.

[0026] Such as figure 2 As shown, the hydraulic source casing 1 is fixed on the bottom of the mechanical arm through threads, and two stepped holes are opened on the side thereof to connect with the oil injection module and the partition module. The inner ends of the oil injection module and the partition module are provided with a connected oil injection chamber 18 ,...

Abstract

The invention discloses a fast oiling mechanism for a hydraulic locking mechanical arm. The fast oiling mechanism comprises a hydraulic source part, wherein the hydraulic source part comprises a hydraulic source shell, a hydraulic source piston and a first articulated shaft which is in clearance fit with the hydraulic source shell, wherein hydraulic oil pipelines which are communicated with each other are formed on the first articulated shaft and the hydraulic source shell; sides of the hydraulic source shell are connected with an oil injection module and a separation module; the inner ends of the oil injection module and the separation module are provided with oil injection cavities which are communicated with each other; a connecting hole is formed in the hydraulic source shell; the oil injection cavities are connected with the hydraulic oil pipelines through the connecting hole; and the separation module controls the opening and closing of the connecting hole. The oil injection module is matched with the separation module, so that the mechanical arm hydraulic system can be rapidly oiled and quantified so as to be finely adjusted.

Description

technical field [0001] The invention relates to an oiling device for a surgical manipulator adopting a hydraulic locking method, in particular to a rapid oiling mechanism for a hydraulically locked manipulator. Background technique [0002] In recent years, the minimally invasive surgical manipulator technology that combines computer, image processing, medical surgery technology and medical robots has become one of the international frontier hotspots that many scholars and scientific research institutions pay attention to. The development of this new multidisciplinary field is considered to be a symbolic progress in surgical treatment, and the research and development of domestic medical equipment is increasing. At present, there are relatively few clinical applications of passive puncture positioning robotic arms. One of the important reasons is that there are some deficiencies in the joint locking structure of surgical robotic arms, especially for small and light joints th...
