Description

Technical Field

[0001] The invention relates to the technical field of medical laser lithotripsy, and in particular to a lithotripsy device for gastric calculus surgery with a protective device. Background Art

[0002] Gastric lithiasis is mostly caused by plant-based gastric stones. It is caused by eating too much persimmon, black dates, hawthorn, etc. on an empty stomach. Gastric persimmon stones are the most common. Clinically, it is often complicated by gastric ulcers, upper gastrointestinal bleeding, pyloric obstruction, etc. The traditional treatment method for gastric stones is usually surgical removal of stones. Its disadvantages are that it requires paralysis for laparotomy, and there are certain risks during the operation. It is easy to get infected after the operation, the course of the disease is long, and the cost is high. In recent years, with the development of endoscopic technology, endoscopic stone removal and lithotripsy have made progress in clinical practice, such as the more advanced laser blasting lithotripsy and ultrasonic lithotripsy. The existing laser lithotripsy usually inserts a laser lithotripsy device into the stomach for lithotripsy.

[0003] After searching, a Chinese patent with publication number CN 108338837 A mentioned a lithotripsy device for gastric stone surgery with a protective device, including a laser lithotripsy device, a fixed sleeve is sleeved on the surface of the laser lithotripsy device, air guide tubes are fixedly installed on both sides of the fixed sleeve, and the air guide tubes are fixedly installed on the two side walls of the fixed sleeve, so that the gas can be transported to the inside of the air guide port through the air guide tubes, and limiting plates are provided on both sides of the balloon to limit the balloon so that the balloon moves toward the cover plate to open the cover plate, and a magnet is fixedly installed inside the cavity opened on the opposite side of the protective sleeve to better fix the protective sleeve on the outer wall of the fixed sleeve, and a squeezing ball is installed at the lower end of the air inlet pipe, and an air inlet hole is opened on the surface of the squeezing ball, and a stop valve is installed at the lower end of the air inlet pipe, and the balloon is expanded by pressing the squeezing ball, and the air inlet pipe can be sealed through the stop valve, so that the balloon is not easy to leak.

[0004] The above-mentioned device has disadvantages in its specific use. When medical staff insert the laser lithotripsy device into the patient's stomach through the esophagus, since the stones are in direct contact with the gastric lining mucosa, the laser lithotripsy device is then used to directly crush the stones, which will further cause the stones and the gastric lining mucosa to move relative to each other, and there is a possibility of damaging the gastric lining mucosa.
