AI Technical Summary

Technical Problem

The existing method of assembling surgical instruments with the power box of the operating equipment takes up a lot of space and is prone to causing interference between the robotic arm and the patient.

Method used

By setting multiple mounting interfaces on the inner and end wall surfaces of the main boom section, with some telescopic arms mounted on the inner wall surface and some on the end wall surface, the telescopic arms can be accommodated in a smaller amount of internal space within the main boom section. Combined with the avoidance ramp design of the transfer components and drive device, the overall size of the robotic arm is reduced.

Benefits of technology

This effectively reduces the overall size of the robotic arm, lowers the risk of interference with the patient, and improves the flexibility and safety of the surgery.

Abstract

The present application relates to a kind of end joint arm, mechanical arm and medical trolley, end joint arm includes main arm section and multiple installation interfaces, main arm section has first circular arc movement trajectory, first circular arc movement trajectory has virtual central axis, main arm section has the inner wall surface facing virtual central axis, the outer wall surface away from virtual central axis, and end wall surface between the inner wall surface and the outer wall surface at the end of main arm section, part of multiple installation interfaces telescopic arm is installed in inner wall surface, another part of multiple installation interfaces installation interface is installed in end wall surface.Compared with telescopic arm all being installed in the inner wall surface of main arm section, in turn, all needing the internal space of main arm section to be contained, obviously, the internal space size of main arm section needed to contain less telescopic arm is smaller, the size of main arm section is reduced, so as to reduce the interference of mechanical arm to patient, in turn, solve the problem of mutual interference between mechanical arm and patient.
