Embodiment Construction

[0060] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0061] It should be noted that when a component is said to be "mounted on" another component, it may be directly mounted on another component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly...

Abstract

The invention provides a surgical mechanical arm. The surgical mechanical arm comprises a pre-surgical positioning assembly, a telecentric control assembly and an executing assembly. The telecentric control assembly includes a fixed platform, a first moving platform and a plurality of first telescopic elements disposed between the fixed platform and the first moving platform; the executing assembly has a preset telecentric fixed point; coordinated expansion and contraction between the multiple first telescopic elements can control the first moving platform to move relative to the fixed platform and the executing assembly is driven to extend and retract and swing; and the swing center of the executing assembly is the telecentric fixed point, and a telescopic path of the executing assembly passes through the telecentric fixed point. According to the surgical mechanical arm provided by the invention, a parallel mechanism is composed through the first moving platform, the fixed platform and the plurality of first telescopic elements located between the first moving platform and the fixed platform, and the movement accuracy of the executing assembly at the tail end is improved by utilizing the error non-cumulative characteristic of the parallel mechanism; and meanwhile, surgical operation of the executing assembly under a higher load can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical robot arm and a surgical robot. Background technique [0002] The birth of minimally invasive surgery largely overcomes the shortcomings of traditional surgery such as large incision, large amount of bleeding, many complications and high surgical risk. Due to the rapid development in recent years, minimally invasive surgery is gradually gaining the favor of medical staff and patients, and has become an emerging field of medical research and clinical application. [0003] Using surgical robots to assist doctors in minimally invasive surgery can make surgical operations more sensitive and precise. Take the da Vinci surgical robot as an example. The da Vinci surgical robot can magnify the doctor's field of view ten times while effectively filtering out the doctor's hand tremors. It has a wide range of clinical applications in the field of minimally invasive s...
