Visual gas abdominal puncture needle

Abstract

The invention discloses a visual gas abdominal puncture needle, and relates to the technical field of medical apparatus. The visual gas abdominal puncture needle comprises a puncture needle head, a needle tubing, a handle, a gas outlet, a camera, an adjusting valve and a gas inlet, the puncture needle head is connected to the front end of the needle tubing in a sleeved mode, the camera is arranged in the puncture needle head in an embedded mode, the gas outlet is formed in the puncture needle head, the handle is arranged on the outer portion of the needle tubing, the adjusting valve is installed on a tube body of the rear portion of the handle, the gas inlet is located at the tail end of the needle tubing, the camera is connected with a video camera connecting wire, the video camera connecting wire penetrates out of a needle body from the rear portion of the handle, the tail end of the video camera connecting wire is connected to a connector, the other connector is connected with a display screen through a display screen connecting wire, and when the two connectors are in connection, images collected by the camera can be transmitted and displayed. According to the visual gas abdominal puncture needle, puncture positioning is accurate, operation time is saved, damage to a patient and risks of a surgery are reduced, and application and popularization are easy.

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
