A spatial multi-degree-of-freedom surgery auxiliary arm mechanism

Abstract

The invention discloses a spatial multi-degree-of-freedom surgery assisting arm mechanism, which comprises an arm bracket, a touch hand assembly and a motion component which is connected between the touch hand assembly and the arm bracket and is used for conducting three-dimensional direction adjustment on the touch hand assembly, wherein the touch hand assembly comprises a touch hand mounting tray and a plurality of touch hands which are fixedly arranged on the touch hand mounting tray; each of the touch hands is formed by hinging a plurality of touch hand sub-sections, and an elastic limiting piece, which is used for limiting a relative rotating angle between every two adjacent touch hand sub-sections, is arranged between the every two adjacent touch hand sub-sections; the motion component comprises a horizontal direction adjusting unit and a vertical direction adjusting unit; and the positions of both the horizontal direction adjusting unit and the vertical direction adjusting unit are adjusted by virtue of a worm-gear pair structure. The arm mechanism disclosed by the invention is simple and efficient to operate and low in cost, and is suitable for assisting doctors in various surgical operations.

Description

technical field [0001] The invention relates to a mechanical arm mechanism, in particular to a self-locking and gradient-adjustable arm mechanism capable of moving in multiple positions in space. Background technique [0002] When a doctor is performing a surgical operation or performing a simulated operation, the operation of the two hands is limited, and generally requires the help of an assistant. The assistant will help the doctor to take the surgical instruments, help the clamping biological tissue, and cut the tissue. The assistant will shake hands. Some tissues or organs will block the doctor's view during the operation, and assistants need to use corresponding instruments to remove the tissues or organs so that the doctor can continue the operation. However, many areas that require surgery are small areas. In the process of assisting the doctor, the assistant will block the doctor's sight and hinder the operation, or in order to widen the field of vision, the area o...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned documents are mainly aimed at the overall improvement of the operating table, and the setting of its fixed points is also aimed at the fixation of the body and limbs of the surgical patient, and there is no structural design for fixing the tissue of the surgical site.

Moreover, the schemes mentioned in the above-mentioned documents generally have a relatively complicated structure. If a problem occurs in one component, the entire operating table needs to be replaced, and the cost of use is relatively high.
