Slave end actuator device of interventional operation robot

Abstract

Disclosed is a slave end actuator device of an interventional operation robot. The slave end actuator device is used for pushing slender medical instruments in an interventional operation to move. The slave end actuator device of the interventional operation robot comprises a shell, a driving device arranged in the shell and extending out of the shell, and a sterile isolation device for sealing the shell; and one end of the driving device penetrates through the sterile isolation device, and in the process that the driving device clamps and pushes the slender medical instrument in the interventional operation to move, the sterile isolation device is kept in close contact with the driving device. The non-consumable part is kept sealed, the situation that the non-consumable part is completely exposed in the air and then polluted is effectively prevented, the safety of an interventional operation is effectively improved, life health and safety of a patient are guaranteed, practicability is high, and the application range of the interventional operation is widened.

Description

technical field [0001] The invention relates to a device in the field of medical instrument robot, in particular to a slave end effector device of an interventional operation robot. Background technique [0002] Interventional therapy is a minimally invasive treatment using modern high-tech means—that is, under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body to diagnose and locally treat pathological conditions in the body. [0003] The application of digital technology in interventional therapy expands the doctor's field of vision, and extends the doctor's hands with the help of catheters and guide wires. Its incision (puncture point) is only the size of a grain of rice, and it can treat many diseases that could not be treated in the past and must be treated without cutting human tissue. Surgical treatment or medical treatment of poor efficacy of disease, such as tumors, hemangiomas...

AI Technical Summary

Problems solved by technology

[0005] In the process of advancing, retreating and rotating the guide wire (or catheter), the surgical robot needs to be driven by a corresponding transmission mechanism. The connection between the guide wire (or catheter) and the transmission mechanism is a major problem for engineers in the industry, because The transmission mechanism must not only realize the control of the guide wire (or catheter), but also ensure that the non-consumable parts of the transmission mechanism are not polluted by residual fluid such as blood coagulation during the operation. Limiting the development of surgical robots to a certain extent, it is urgent to improve the structure of traditional surgical robots
