Problems solved by technology

However, the slender puncture needle of this lung puncture robot is bent due to uneven force on the needle tip, resulting in inaccurate puncture target points, and as the needle gradually sinks into the tissue, its resistance gradually increases, making it easier for the needle to puncture. Deformation, causing deviation in the position of the puncture target, affecting the accuracy of the operation

Abstract

The invention provides a lung puncture surgical robot which comprises a stand column, a lead screw and a sliding block are arranged in the z-axis direction, the y-axis direction and the x-axis direction respectively for multi-dimensional adjustment, a mechanical arm is further arranged at the tail end of the multi-adjustment lead screw, the end of the mechanical arm is fixedly connected with one end of a puncture needle, the puncture needle extends in the z-axis direction, a supporting plate is further arranged on a supporting frame, and the supporting plate is fixedly connected with the supporting frame. A through hole is formed in the supporting plate, and the needle tip of the puncture needle penetrates through the through hole and extends towards the z axis. The lung puncture surgical robot is high in puncture precision and automation degree.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a lung puncture operation robot. Background technique [0002] In traditional puncture surgery, doctors use X-ray, CT, ultrasound and other medical influences to insert the puncture needle into the target with bare hands. This method relies on the operator's hand-eye collaboration, and it is difficult to ensure the puncture accuracy and the continuity of needle insertion. At the same time, the doctor has the risk of radiation exposure. Completing the puncture by a robot can overcome the disturbance of the tremor of the human hand, improve the puncture accuracy, and at the same time facilitate the dexterous operation of the puncture needle. [0003] The existing Chinese utility model patent with the authorization announcement number CN209951390U and the name is a manipulator terminal device and a lung puncture robot using the device discloses a puncture needle, a line...
