Disposable endoscope sheath

Abstract

The invention provides a disposable endoscope sheath which comprises an insertion portion, a control portion and an endoscope locking portion, wherein the insertion portion comprises a sheath end and a sheath tube, the control portion comprises a main body, a water inlet and outlet valve and a machine adjusting knob, and the endoscope locking portion comprises a telescopic endoscope bridge, a locking sleeve and a protection cover. The sheath end is positioned in front of the insertion portion, the back of the sheath end is connected with the sheath tube which is connected with the telescopic endoscope bridge of the endoscope locking portion through the main body, and the water inlet and outlet valve and the machine adjusting knob are positioned on a main body of the endoscope sheath. The sheath tube is of a multichannel structure, and scale marks are arranged on the outer surface of the insertion portion. The disposable endoscope sheath has the advantages of avoiding cross infection and being adaptive to needs of different endoscopic surgeries.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a disposable endoscope sheath. Background technique [0002] Conventional cystoscopic surgical instruments and hysteroscopic surgical instruments are mainly made of stainless steel, and stainless steel surgical instruments are open instruments, which cannot completely seal the endoscope during use. By inserting into the sheath-type instrument to work, the body fluid substances generated during the human operation process will pollute the endoscope, and the postoperative endoscope must be sterilized. A kind of endoscope sheath that carries out fully enclosed protection to endoscope has appeared on the market at present. The endoscope is on the inside and the sheath is on the outside. Since the endoscope is not in contact with anyone, it is the endoscope sheath that directly contacts the human body. At the same time, the human body will not pollute the endoscope, reducing cros...

Problems solved by technology

[0003] The Chinese patent with the authorized notification number CN100569175C discloses a disposable cystoscope sheath, which provides a dual-channel sheath structure capable of simultaneously accommodating endoscopes and surgical instruments into the human body for diagnosis and treatment, but the sheath structure simultaneously There are also problems: First of all, the instruments mainly used in endoscopic surgery include different tools such as pliers and scissors. Angle swing, sometimes with a certain amount of rotation to meet more surgical needs

On the other hand, during endoscopic surgery, it is sometimes difficult for medical staff to judge the insertion depth of the endoscopic sheath, so there is still a need for a method that can clearly indicate the insertion depth of the sheath

[0005] In the current operation, sometimes due to the patient's massive bleeding, body fluids will be sprayed out in large quantities. At this time, the rear end of the endoscope main body and the part connected to the follow-up CCD system may also be polluted by body fluids. Therefore, there is an urgent need for a device that can The mirror sheath structure that protects the rear end of the endoscope main body and the subsequent CCD system and cables when a large amount of human body fluids gushes out
