Access assembly for endoscope and using method of access access assembly

Abstract

The application discloses an access assembly for an endoscope. The access assembly comprises a tubular body for receiving the endoscope, a far-end piece, a near-end piece, a fluid supply passage, a vacuum suction part and a three-way pipe; the far-end piece is connected with the far end of the tubular body; the near-end piece is connected with the near end of the tubular body, wherein the inner wall of the tubular body, the far-direction surface of the near-end piece and the near-direction surface of the far-end piece jointly define a cavity of the access assembly; the fluid supply passage comprises a fluid input port, a fluid discharge port and a fluid pipeline; the fluid input port and the fluid discharge port are in fluid communication through the fluid pipeline, and the fluid discharge port is arranged in the cavity of the access assembly; and the vacuum suction part is configured to be connected with a vacuum suction source. The invention also relates to a using method of the access assembly.

Description

technical field [0001] The present application relates to an access assembly for an endoscope and a method of use thereof. Background technique [0002] Minimal invasive surgery such as endoscopic surgery reduces the invasiveness of the surgical procedure. Endoscopic surgery involves surgical procedures through the body wall, eg, to view and / or operate on the ovaries, uterus, gallbladder, bowel, kidneys, appendix, etc. There are many common endoscopic surgical procedures including, for example, arthroscopy, laparoscopy, gastroenteroscopy, and laryngobronchoscopy. In these methods, a trocar is used to create an incision through which endoscopic surgery is performed. A trocar tube or access assembly extends into and remains in the body cavity to provide access to endoscopic surgical tools. A camera or endoscope is inserted through the access assembly to allow visual inspection and magnification of the body cavity. The surgeon can then perform diagnosis and / or treatment at ...

AI Technical Summary

Problems solved by technology

During a surgical procedure, the time required to clean the lens can increase the overall time of the procedure and the amount of time the patient needs to remain under anesthesia, and since the endoscope is repeatedly withdrawn and inserted into incisions on the patient's body, this can lead to an increased risk of infection and increase recovery time

Although there are some access assemblies that are capable of flushing the lens of an endoscope with fluid in the body cavity, because these access assemblies directly drain the irrigation fluid along with condensate, tissue, blood, and other bodily fluids, etc. into the patient's body cavity, Therefore, it is not accepted by most surgeons and has not been promoted.

In addition, due to the limited scouring force, using a continuous phase liquid (such as saline) alone to clean the endoscope lens may not be able to completely remove sticky dirt such as tissue and grease adhering to the lens
