Peritoneal fluid extraction pipeline

Abstract

The invention provides a peritoneal fluid extraction pipeline. The pipeline comprises: a liquid inlet section which is provided with a plurality of liquid inlet grooves which are separated from one another and extend in the axial direction; a middle section which is connected to one end of the liquid inlet section, and is internally provided with a plurality of connecting channels which are separated from one another and communicate with a plurality of the liquid inlet grooves one by one; a drainage section which is connected to the end, far from the liquid inlet section, of the middle section, and is internally provided with a drainage channel communicating with the connecting channels; and a fluid extraction section which is mounted at one end, far from the middle section, of the drainage section and used for being hermetically connected to an aspirator. The peritoneal fluid extraction pipeline is simple in structure and low in cost, therefore, peritoneal fluid can be simply extracted at low cost, and the requirement for disposable use is met. Meanwhile, when the structure is used for extracting the peritoneal fluid, the peritoneal fluid is not prone to being blocked by abdominalcavity contents such as omentum majus, peritoneum paralium and mesenteric, cells in ascites and peritoneal irrigation fluid can be efficiently extracted, and the accuracy of exfoliated cell examination is guaranteed. In addition, the structure can also avoid splashing of body fluid due to pneumoperitoneum pressure under laparoscopic surgery.

Description

technical field [0001] Embodiments of the present disclosure generally relate to surgical instruments in abdominal surgery, and more specifically, relate to a device that provides convenient operation during surgery to facilitate the extraction of peritoneal fluid such as peritoneal washings or ascites during laparoscopic surgery and laparotomy. pipeline. Background technique [0002] Gastric cancer and colorectal cancer are one of the common malignant tumors of the digestive tract, and their incidence rates are increasing year by year. Highly malignant tumors such as gastric cancer and colorectal cancer are prone to secondary peritoneal metastasis, thereby reducing the survival time of patients. Extracting peritoneal fluid such as ascites or peritoneal washing fluid for exfoliative cytology examination can confirm whether there is peritoneal metastasis in malignant tumors such as gastric cancer and colorectal cancer. Complicated and expensive. In order to prevent the spr...
