Problems solved by technology

However, interference with the pubic bone is unavoidable in prostate biopsy
Some instruments are simple in structure and easy to operate, but they are difficult to use in more complicated operations
Some instruments are difficult to control the accuracy
Some instrument control systems are more complex and inconvenient for professional doctors to master
The main research difficulties are: (1) The configuration of the robot in a confined space has always been a difficult point in the design; (2) The problems between the robot and the magnetic resonance environment are also difficult to solve, including material compatibility, drive compatibility, Sensor Compatibility and Structural Compatibility

Description

technical field [0001] The invention relates to the technical field of medical robots, in particular to the field of minimally invasive medical robots. Background technique [0002] At present, dozens of magnetic resonance compatible puncture surgical robots have been invented, which can perform prostate biopsy and seed implantation in the first place. They have solved the problem of magnetic resonance compatibility by using magnetic resonance compatible materials in the magnetic resonance environment. Some instruments realize vertical and horizontal translation and rotation. Under the guidance of magnetic resonance, the tracking accuracy reaches the millimeter level, and high needle insertion accuracy is obtained. However, it is difficult to avoid interference with the pubic bone in prostate biopsy. Some instruments are simple in structure and easy to operate, but are difficult to be used in more complicated operations. Some instruments are difficult to control the accur...
