Endoscopic Pneumoperitoneum Atraumatic Aspirator Head Device

Abstract

The invention discloses a head-end device of a pneumoperitoneum non-injury suction device for laparoscopy, comprising: a suction tube, a control valve, a sponge ball for dipping and suction, and a sponge ball controller. The suction tube is an intermediate support structure, the rear end communicates with the inner cavity of the control valve, and the top end of the suction tube is connected with a dipping sponge ball, and the two are screwed together and sealed. The dipping sponge ball includes the outer conical bracket, the connecting web between the conical brackets, the elastic sponge in the conical bracket and the arc top formed by the one-way water-permeable composite fiber membrane at the front end, which can ensure the one-way circulation of the suctioned peritoneal fluid. Prevents backflow of the aspiration fluid and reduces the possibility of damaging the pneumoperitoneum. The sponge ball controller is set outside the dipping and suctioning sponge ball, which can control the opening and closing of the dipping and suctioning sponge ball, so as to facilitate the insertion or removal of the tip device of the pneumoperitoneum non-invasive aspirator for laparoscopy from the puncture hole of the abdominal wall. The invention is more suitable for pneumoperitoneum laparoscopic operation.

Description

technical field [0001] The invention relates to the technical field of instruments for minimally invasive surgery, in particular to a head end device of a pneumoperitoneum non-invasive aspirator for laparoscopy. Background technique [0002] Laparoscopic surgery is a minimally invasive surgical technique. Due to the advantages of small intraoperative trauma and fast postoperative recovery, it has rapidly emerged in recent years. Laparoscopic surgery has been widely used in general surgery, obstetrics and gynecology, urology, bone and joint surgery Surgery, Thyroid and Breast Surgery, etc. During laparoscopic surgery, a good surgical field of view and operating space are the key to ensure the smooth progress of the operation, and effective insufflation pressure (maintain the insufflation pressure at 12mmHg-16mmHg through CO2 insufflation machine) and clean (no bleeding) ) surgical wound is an important guarantee for laparoscopic surgery. At present, in laparoscopic surgery,...

AI Technical Summary

Problems solved by technology

At present, in laparoscopic surgery, the main methods for clearing wound bleeding and exudate are aspirator suction and gauze dipping. The gas is sucked away together, resulting in the collapse of the abdominal wall, and the rapid disappearance of the observation and operation space. It is necessary to wait for continuous inflation to establish a pneumoperitoneum space before continuing to observe and operate, which will delay the best observation time point and surgical operation timing; The gauze is generally a small square gauze, and the small square gauze is only suitable for bleeding and exudate, and the surgical instrument needs to be replaced repeatedly during use, which will delay the operation time

At present, there is no relevant device or product at home and abroad to meet this clinical demand. There is an urgent need for a special medical surgical instrument that can be applied to suck bleeding and exudate in laparoscopic surgery without destroying the pneumoperitoneum pressure and observation space. and applicable to the actual clinical situation
