Fixed-point puncture device and robot using the fixed-point puncture device

Abstract

The invention discloses a fixed-point puncture device and a robot using the fixed-point puncture device, and relates to the field of medical robots. The robot mainly comprises a fixed-point puncture device, an SCARA type mechanical arm, a driving motor and a base. The SCARA type mechanical arm can meet the requirements of high positioning precision and large working range of a medical robot, the fixed-point puncture device can realize the fixed-point variable-angle movement of a puncture needle, and the fixed-point puncture device and the SCARA type mechanical arm can realize the posture adjustment and control of the puncture needle. The driving force of the fixed point puncture device is provided by the driving motor, and each rotary joint of the robot is driven and braked by the drivingmotor, so that it is convenient for the robot to conveniently adjust the posture and keep the current state. The invention designs the fixed-point puncture device and the robot using the fixed-point puncture device to assist a doctor in the fixed-point puncture diagnosis, thus making up for the defects of manual puncture and improving the stability of puncture and the success rate of diagnosis.

Description

technical field [0001] The patent of the present invention belongs to the field of medical robots, and specifically relates to a fixed-point puncture device and a robot using the device. Background technique [0002] In clinical medical work, puncture is a relatively common treatment method, but there are still many defects in purely manual puncture by doctors, for example: the accuracy of two-dimensional puncture in three-dimensional space cannot be guaranteed, and doctors need to observe the needle tip at any time Once the hand trembles or the puncture force is uneven, it is easy to cause postoperative complications and even seriously threaten the life safety of the patient. [0003] During the puncture operation, the doctor may need to retract the needle several times when manually feeding the puncture needle to accurately puncture the target point. In this case, it will increase the pain of the patient during the operation and cause tension to the doctor and the patient....

Problems solved by technology

[0002] In clinical medical work, puncture is a relatively common treatment method, but there are still many defects in purely manual puncture by doctors, for example: the accuracy of two-dimensional puncture in three-dimensional space cannot be guaranteed, and doctors need to observe the needle tip at any time Once the hand trembles or the puncture force is uneven, it is easy to cause postoperative complications and even seriously threaten the patient's life.

[0003] During the puncture operation, the doctor may need to retract the needle several times when manually feeding the puncture needle to accurately puncture the target point. In this case, it will increase the pain of the patient during the operation and cause tension to the doctor and the patient. Psychologically, the operation time is prolonged, the operation efficiency is reduced, and the puncture needle cannot reach any puncture posture during manual puncture, and the working range of the puncture needle is limited
