The puncture needle is simple in structure, reasonable in design and suitable for being popularized and used.
Description
technical field [0001] The invention relates to the technical field of medical instruments and equipment, in particular to a puncture needle for gastrointestinal and abdominal surgery. Background technique [0002] Laparoscopic surgery is a modern high-tech medical technology. Laparoscope is an endoscope used for intraperitoneal examination and treatment. It is applied to patients in a completely painless situation. It can directly and clearly observe the situation in the patient's abdominal cavity and understand the pathogenic factors. At the same time, surgical treatment is performed for abnormal conditions. Laparoscopic surgery is performed using a laparoscope and its related instruments: use a cold light source to provide illumination, insert the laparoscopic lens into the abdominal cavity, and use digital camera technology to transmit the image captured by the laparoscope lens to the subsequent signal through the optical fiber. processing system and is displayed in rea...
