Abstract
Description
Technical Field
[0001] This application relates to the field of medical device technology, and more specifically, to a compliantly adjustable puncture robot. Background Technology
[0002] Puncture surgery, an indispensable diagnostic and treatment method in modern medicine, is widely used in various fields such as tumor biopsy, ablation therapy, and drug injection. However, traditional manual puncture methods often suffer from problems such as difficulty in localization, significant path deviation, and operational instability when dealing with deep lesions. Maintaining high precision for extended periods also places extremely high demands on the surgeon's physical strength and concentration, and surgical fatigue can easily further affect the quality of the procedure. With the rapid development of robotics technology, puncture robots are gradually becoming an important direction for solving these problems. Compared with traditional manual operations, the stability and repeatability of robotic systems effectively alleviate the surgeon's operational pressure and improve surgical efficiency and safety. Therefore, conducting research on puncture robots not only has significant clinical value but also represents an important trend in the future development of intelligent healthcare.
[0003] A search revealed a Chinese invention patent with publication number CN118217024A, which relates to a handheld RCM puncture robot. This robot aligns its center of gravity, the puncture target point, and the doctor's palm at a single point, allowing the entire device to be directly worn on the doctor's forearm without requiring additional torque, thus reducing effort during operation. The puncture unit is directly held by the doctor, and the compact design makes it suitable for operations in narrow spaces such as those used in CT or MRI scans. However, the forearm-fixed wearing method places additional demands on the doctor's arm circumference and padding method, requiring re-wearing and recalibration if switching to a different doctor.
[0004] A search revealed Chinese invention patent application CN118576323A, which relates to an exoskeleton device for a handheld puncture robot. This device is secured by wearing it on the forearm and holding it in the hand, and is relatively lightweight, making it easy for doctors to hold for extended periods. The device also includes a sensor module to collect the doctor's movements, which, along with the drive module, assists the doctor in performing the puncture procedure. However, it still suffers from the problem of needing to re-wear the device when switching doctors.
[0005] A search revealed a Chinese utility model patent with publication number CN218552380U, which relates to a handheld, angle-adjustable medical puncture device. This device can read the needle insertion angle in real time via a scale, enabling angle control and improving puncture accuracy. However, the device is relatively large, making it difficult to use with an ultrasound probe for puncture procedures.
[0006] In summary, traditional manual puncture suffers from difficulties in locating deep lesions, significant deviations in puncture paths, and insufficient operational stability. Furthermore, prolonged operation can easily lead to fatigue for doctors, thus affecting the quality of the surgery. While existing wearable puncture robots improve operational convenience and stability, they have drawbacks such as high requirements for operator adaptation, the need for recalibration when switching between different doctors, and insufficient clinical adaptability. Although existing handheld angle-adjustable puncture devices can achieve precise control of the puncture angle, their large overall size makes them difficult to coordinate with ultrasound probes, limiting their practicality.
[0007] Therefore, there is an urgent need to design a compact, flexibly adjustable puncture robot that integrates the ultrasound probe and the puncture needle. This robot would not only meet the needs of doctors to operate it directly by hand, but also be easy to disassemble, store, and carry. This would effectively solve the aforementioned technical problems and improve the accuracy, convenience, and clinical suitability of puncture surgery. Summary of the Invention

[0060] In some specific embodiments of this application, when the insertion angle of the puncture needle 212 is adjusted using the puncture needle posture adjustment mechanism 2, the inner ring 205 of the bearing rotates around the optical axis at the end of the limiting screw 206, which drives the rotation of the guide rail mounting base 207. This allows the insertion angle of the puncture needle 212 to be adjusted. After the target angle is reached, the guide rail slider 209 and the feed slider 210 move linearly along the guide rail 208 to achieve the forward and backward adjustment of the puncture needle 212.
