Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0042] Such as figure 1 As shown, it can be seen that the robot operating mechanism for multi-joint single-injury oral and abdominal minimally invasive surgery is composed of a mechanical arm and a power part. In this embodiment, the power part is realized by a motor box 2. Two connecting arms 11, 22 and two tip manipulators 13, 20 with the same structure, the end of the tip manipulator is equipped with a knife head, which can rotate flexibly; the structure of the knife head is similar to scissors...

Abstract

The invention provides a multi-joint single-wound abdominal cavity minimally-invasive surgery robot and an operating mechanism thereof. The operating mechanism comprises a mechanical arm and a power part. The mechanical arm comprises a connecting rack and two arms with the same structure. Each arm comprises a connecting arm and an advanced manipulator. A cutter head is installed at the end of the advanced manipulator. The two advanced manipulators are respectively and detachably installed at the ends of the two connecting arms. The two connecting arms are respectively installed on the two sides of the connecting rack. The connecting rack is detachably connected with the power part through a connecting pipe. The operating mechanism is installed on a four-freedom robot. The operating mechanism is designed for abdominal cavity surgeries, the effect of a single wound can be realized, the diameter of the wound is 10-20mm and the requirement on the minimal invasiveness of the surgeries is satisfied. Besides, the strength is enough, and the accuracy, the flexibility, the stability and the safety of the operating mechanism during surgeries are guaranteed.

Description

technical field [0001] The invention relates to surgical medical equipment, in particular to a multi-joint single-incision oro-abdominal minimally invasive surgery robot and its operating mechanism. Background technique [0002] With the rapid development of human science and technology and the continuous improvement of living standards, people have higher and higher requirements for surgical safety, accuracy and minimal invasiveness. Surgical robotic systems can meet this need. Compared with traditional surgical methods, the main advantages of surgical robots are: [0003] (1) It can provide surgeons with a more comprehensive and extensive spatial vision; [0004] (2) It can improve the accuracy of surgery, thereby reducing surgical trauma and blood loss, speeding up recovery, and reducing surgical sequelae and complications; [0005] (3) It can rule out the possible adverse effects of the surgeon's hand tremor on the operation; [0006] (4) It can be operated safely an...
