Interventional channel of abdominal surgery robot

Abstract

The invention relates to an abdominal surgery robot intervention channel which comprises a base, a multi-channel platform, an inner clamping assembly and an outer clamping assembly, and the multi-channel platform comprises an instrument platform, a base, a flexible layer and a mechanical arm channel; the outer side surface of the base is a part of a spherical surface, the base is provided with a spherical inner cavity, and the base is matched with the inner cavity of the base, so that the base can rotate around a plurality of axes in the base; the multiple holes in the instrument platform are spherical holes, the outer surface of the mechanical arm channel is in a spherical surface shape, and the outer surface of the mechanical arm channel is matched with the holes, so that when the monitoring mechanical arm moves, the multi-channel platform can be caused to rotate relative to the base, and the pose of the tool mechanical arm is kept unchanged. And therefore, a larger movement range is provided for the monitoring mechanical arm.

Description

technical field [0001] The invention relates to an interventional channel for an abdominal surgery robot, in particular to an interventional channel that can easily change the surgical field of view, be stably installed and can be reused. Background technique [0002] At present, surgical robots have been increasingly accepted by patients. For example, the Da Vinci surgical robot, which has been commercially applied, has achieved good clinical and social effects in the field of endoscopic surgery. When the surgical robot performs surgery, especially abdominal surgery, at least 3-4 robotic arms should be inserted into the abdominal cavity of the patient, including monitoring robotic arms, at least two tool robotic arms, etc. The purpose of monitoring robotic arms is to monitor tools. The robotic arm displays the surgical process of the tool robotic arm to the remote operator in real time, giving the operator an immersive feeling. In order to enable the monitoring equipment t...

AI Technical Summary

Problems solved by technology

In order to enable the monitoring equipment to have a larger surgical field of view, each robotic arm is usually placed into the abdominal cavity through a puncture device, and there is usually a large distance between the robotic arms to provide a range of field of view adjustment, which is of great concern to patients. Hazard, which requires multiple punctures in the abdominal wall

The single-hole abdominal intervention channel only needs to be punctured once, which reduces the surgical workload and the injury to the patient. However, since multiple robotic arms are placed through one hole, the distance between the monitoring robotic arm and the tool robotic arm is relatively close, and the range of surgical field of view adjustment Smaller, there will be situations where it is impossible to monitor the surgical tools, resulting in surgical failure, and the existing single-port abdominal intervention channel is not suitable for surgical robots
