Description

Disposable adjustable laparoscope puncture cannula sponge cleaning rod

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical equipment, in particular to the technical field of a disposable adjustable laparoscope puncture sleeve sponge cleaning rod.

[ background of the invention ]

The laparoscopic surgery is that a surgical channel is established on the abdominal wall of a patient through a puncture cannula, and then a laparoscope and surgical instruments are placed into an abdominal cavity through the puncture cannula, so that the abdominal cavity condition of the patient is observed, and meanwhile, the surgical instruments are used for performing operations such as cutting, electrocoagulation, observation, ligation and the like on pathological change tissues of the patient. With the development of modern medicine, laparoscopic surgery as minimally invasive surgery has the advantages of small wound, quick recovery, less pain and the like, and gradually replaces the traditional surgery.

During laparoscopic surgery, on one hand, the lens orientation and depth of the laparoscope need to be adjusted frequently by the hand of the laparoscope to ensure that the operator has a good surgical field of view, and on the other hand, bleeding and tissue seepage usually occur in the abdominal cavity of the patient, which may cause contamination of the lens of the laparoscope. The laparoscopic lens needs to be withdrawn along the puncture cannula and wiped. However, in the process of taking out the lens of the laparoscope from the abdomen along the puncture cannula, the hematocele and the hydrops on the lens are easily brought into the puncture cannula and pollute the sealing device of the puncture cannula, and although the conical one-way designed choke valve and the comprehensive sealing valve of the disposable laparoscope puncture cannula have good sealing performance, the endoscope is simply cleaned by adopting a common endoscope gauze and is not easy to clean up in the operation. In the process of wiping the lens and placing the lens into the abdomen along the puncture cannula, the residual hematocele and the effusion are easily stained again, so that the operation image is still unclear, the lens needs to be wiped repeatedly for several times, and the operation time is prolonged. This problem has led to the clinical preference of more operators in using a puncture cannula that extends into a laparoscopic mirror, to using a metal puncture cannula that is easier to scrub, but has relatively poor sealing and securement.

At present, no special puncture cannula cleaning device exists clinically, only can be used for simply cleaning by adopting common gauze, the problem of poor blood accumulation and effusion cleaning effect exists, and especially for the blood accumulation and effusion at a sealing device in the puncture cannula of the disposable laparoscope, certain trouble is brought to a speculum holder and an operator, and urgent solution needs to be provided.
