Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] It should be noted that when a component is said to be "mounted on" another component, it may be directly mounted on another component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or ther...

The present invention provides a surgical robot arm, which includes a preoperative positioning assembly, an executive assembly, and a telecentric control assembly arranged between the preoperative positioning assembly and the executive assembly. The surgical instrument at one end of the central manipulation assembly; the telecentric manipulation assembly is provided with a rotary drive and a sensor, and the rotational drive is connected to one end of the actuator rod that is relatively close to the telecentric manipulation assembly and can drive the actuator rod and the surgical instrument along the axis of the actuator rod. Synchronous rotation; the sensor is connected to the telecentric control assembly and there is no synchronous rotation between the sensor and the surgical instrument along the axial direction of the actuator; the sensor is used to detect the environmental force and / or environmental torque on the surgical instrument. The surgical manipulator provided by the present invention is designed so that there is no synchronous rotation of the sensor and the surgical instrument along the axial direction of the actuator, so that the sensor can be installed in a relatively stable installation environment, and the measurement accuracy of the sensor is improved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical robot arm and a surgical robot. Background technique [0002] The birth of minimally invasive surgery largely overcomes the shortcomings of traditional surgery such as large incision, large amount of bleeding, many complications and high surgical risk. Due to the rapid development in recent years, minimally invasive surgery is gradually gaining the favor of medical staff and patients, and has become an emerging field of medical research and clinical application. [0003] Using surgical robots to assist doctors in minimally invasive surgery can make surgical operations more sensitive and precise. Take the da Vinci surgical robot as an example. The da Vinci surgical robot can magnify the doctor's field of view ten times while effectively filtering out the doctor's hand tremors. It has a wide range of clinical applications in the field of minimally invasive s...
