Puncture surgery robot

Abstract

The invention discloses a puncture surgery robot. The puncture surgery robot comprises a supporting outer frame used for covering the upper side of a patient, a lifting driving assembly arranged in the supporting outer frame, an extending horizontal driving assembly mounted on the lifting driving assembly, a transverse moving driving assembly mounted on the extending horizontal driving assembly, and an extending arm arranged on the lower side of the transverse moving driving assembly, wherein one end of the extending arm extends out of one end of the supporting outer frame, a rotating head is installed at the extending end, an operation part is installed on the rotating head, a puncture needle which slides up and down along the operation part is detachably installed on the operation part, and a first motor for driving the rotating head to rotate, a second motor for driving the operation part to rotate and swing relative to the rotating head and a third motor for driving the puncture needle to slide are mounted on the extending arm. The puncture surgery robot serves a CT-guided tumor interventional operation, can enter a CT scanning environment along with a patient, does not interfere with imaging by artifacts, and is beneficial to improving the navigation positioning speed and accuracy.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a puncture operation robot. Background technique [0002] At present, local thermal ablation, as a minimally invasive technique, has been applied to the treatment of early lung cancer, and the number of treated patients increases rapidly every year. Pulmonary metastases are very common clinically and are the second organ of all tumor metastases. It has been confirmed that percutaneous thermal ablation can also effectively treat lung metastases. The current skin thermal ablation surgery often needs to be performed under the guidance of CT, but now there is a lack of efficacy evaluation standards, doctors cannot see the real-time images of the puncture needle and ablation needle, and repeated / multiple CT irradiation is required. To solve these problems, the current solution The solution is to use a puncture surgery robot, such as the XACT puncture surgery robot, but its positionin...

Problems solved by technology

The current skin thermal ablation surgery often needs to be performed under the guidance of CT, but now there is a lack of efficacy evaluation standards, doctors cannot see the real-time images of the puncture needle and ablation needle, and repeated / multiple CT irradiation is required. To solve these problems, the current solution The solution is to use a puncture surgery robot, such as the XACT puncture surgery robot, but its positioning and navigation needs to be done manually by doctors and the accuracy is limited. The stability and safety of the overall mechanism are insufficient to cope with complex intraoperative scenarios; Its equipment cannot enter the CT ring with the patient for plain scanning, and the generated artifacts interfere with the imaging. It often needs to rely on an additional visual system for navigation and positioning, and the accuracy is difficult to guarantee, which brings a lot of inconvenience to the operation.
