Description

technical field [0001] The invention relates to a four-degree-of-freedom minimally invasive surgical instrument driving platform, specifically a device that provides driving force for a four-freedom minimally invasive surgical instrument and drives the end effector of the surgical instrument to complete the minimally invasive surgical action requirements, belonging to the medical equipment field. Background technique [0002] Traditional minimally invasive surgical instruments have less freedom, poor flexibility, and require manual operation. It is difficult for doctors to ensure the accuracy and accuracy of manual operation for a long time. This drive platform is specially designed to provide a source of power for four-degree-of-freedom minimally invasive surgical instruments and make it easier to control. Contents of the invention [0003] In view of the above shortcomings, the present invention provides a four-degree-of-freedom minimally invasive surgical instrument dr...

AI Technical Summary

Problems solved by technology

[0002] Traditional minimally invasive surgical instruments have less freedom, poor flexibility, and require manual operation. It is difficult for doctors to ensure the accuracy and accuracy of manual operation for a long time. At the same time, minimally invasive surgical instruments have smaller wounds and shorter healing time, which can reduce the pain of patients.
