Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, and in particular discloses an automatic puncture robot for percutaneous nephroscopic surgery. Background Art

[0002] Percutaneous nephrolithotomy, commonly known as "punch lithotripsy", is a procedure that involves making an incision of about 0.5 cm on the patient's waist, establishing a stone removal channel, inserting a nephroscope, and crushing the stones using lithotripsy equipment such as ultrasound, pneumatic ballistics, or holmium laser. It is suitable for symptoms such as large kidney stones and upper ureteral stones. It has become the main treatment method for kidney stones and upper ureteral stones together with ureteroscopy and extracorporeal shock wave lithotripsy, and can save kidney stones from surgical intervention. When existing doctors perform puncture surgery on patients, they use medical imaging guidance such as CT and X-ray machines to locate the puncture point on the body surface, and then perform the puncture surgery manually based on their own experience. For doctors who are not experienced enough, the direction of the needle will be adjusted under the guidance of X-rays until the target position is reached during the puncture process. At this time, they rely too much on the doctor's clinical experience and cannot accurately judge whether the best puncture point has been reached. This not only causes great surgical risks, but also requires repeated adjustments and verifications through medical imaging equipment such as CT until the target position is reached, which exposes patients and medical staff to X-rays for a long time, causing unnecessary radiation damage to medical staff, and the puncture efficiency is low.

[0003] In order to solve the problem of unnecessary surgical risks, the automatic puncture robot for percutaneous nephroscopic surgery in the market uses robots to replace doctors in performing surgical operations manually, and has a certain market share.

The device can realize automatic puncture of lesions, improve puncture efficiency, and reduce radiation hazards to medical staff.

[0005] Based on the above search and in combination with the prior art, it is found that although the prior art uses a puncture robot to replace the doctor's manual operation to solve the problem of unnecessary surgical risks, the motion range of the entire puncture robot is relatively limited, and it is unable to achieve adjustment operations at more angles.

At this time, the main control device 2 controls the X-axis moving platform 7, the Y-axis moving platform 8, the Z-axis moving platform 9, the flip mechanism 10, the first X-axis rotating mechanism 13, the second X-axis rotating mechanism 14 and the rotating motor 17 to operate, and controls the puncture needle 18 to move along the puncture path, that is, the flip mechanism 10 is used to fine-tune the angle of the entire robot structure, so that the puncture needle 18 is rotated in the Z-axis direction, and the X-axis moving platform 7, the Y-axis moving platform 8, the Z-axis moving platform 9, the flip mechanism 10, the first X-axis rotating mechanism 13, the second X-axis rotating mechanism 14 and the rotating motor 17 are used to operate, and the puncture needle 18 is controlled to move along the puncture path. The platform 7, the Y-axis mobile platform 8, and the Z-axis mobile platform 9 adjust the lateral and longitudinal positions of the robot structure, so that the puncture needle 18 can translate in the X-axis, Y-axis, and Z-axis directions. The first X-axis rotation mechanism 13, the second X-axis rotation mechanism 14, and the rotary motor 17 are also used to drive the robot structure to rotate in the X-axis and Y-axis directions, so that the puncture needle 18 can also be adjusted to rotate in the X-axis and Y-axis directions. The entire puncture robot and the puncture needle 18 have 6 degrees of freedom, realizing the operation process of autonomous needle insertion and the needs of adjusting various motion postures.
