Visual gas abdominal puncture needle

Abstract

The invention discloses a visible pneumoperitoneum puncture needle, which relates to the technical field of medical instruments. It includes a puncture needle, a needle tube, a handle, an air outlet, a camera, a regulating valve, and an air injection port. The puncture needle is sleeved on the front end of the needle tube. A regulating valve is installed on the tube body at the rear of the handle, and the end of the needle tube is an air injection port. The camera is connected to the camera connection line, and the camera connection line passes through the needle body behind the handle. The end of the camera connection line is connected to a joint, and the other joint It is connected to the display screen through the display cable, and when the two connectors are connected, the images collected by the camera can be transmitted and displayed. The invention has accurate puncture positioning, saves operation time, reduces patient injuries, reduces operation risks, and is easy to popularize and use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a visible pneumoperitoneum puncture needle. Background technique [0002] Paracentesis refers to a diagnosis and treatment technique that directly penetrates the peritoneal cavity from the front wall of the abdomen with the help of a pneumoperitoneum needle, which is used to clarify the nature of the peritoneal effusion, extract ascites, and inject drugs into the peritoneal cavity. Current status of pneumoperitoneum needles: [0003] (1) At present, the pneumoperitoneum puncture needle is used to enter the abdominal cavity blindly. After the puncture needle penetrates into the skin and enters a certain depth based on experience, the descending speed of water in the syringe can be used to judge whether it has entered the abdominal cavity. However, due to the difference in body fat and thinness, the depth of the subcutaneous tissue is also different, so it is difficult...

AI Technical Summary

Problems solved by technology

However, due to the difference in body fat and thinness, the depth of the subcutaneous tissue is also different, so it is difficult to grasp the depth of the puncture; there are differences in the degree of porosity of the subcutaneous tissue, and patients with loose muscles and a lot of fat are looser; patients with strong muscles and less fat It is relatively tight; the pressure in the abdominal cavity is different; the rate of decline of the water in the syringe is also different, so it is difficult to judge whether it has entered the abdominal cavity by the rate of decline of the water

[0004] (2) Due to the above reasons, there are difficulties in puncture positioning, and many inexperienced doctors have repeatedly punctured, which wastes time and increases the injury of the patient; if the puncture needle fails to enter the abdominal cavity, carbon dioxide can be inflated, which directly leads to subcutaneous tissue in the patient. Complications such as emphysema increase the patient's surgical risk
