Problems solved by technology

There are many important developments in the large number of patent applications published by Pentax Corporation of Japan on this basis in the future. However, as far as the above-mentioned applications have been published, there is still a long way to go for the clinical application of the finished product, and many details need to be improved, such as: endoscopy In the mirror system, there are deficiencies in the position of the water injection and air injection pipes, other positioning and connection structures, and post-treatment of disposable pipes, and new ways need to be explored.

Embodiment Construction

[0036] As shown in Figures 1-6, the endoscope system with a disposable sheath includes two parts: a disposable sheath and a multiple-use endoscope.

[0037] First, the traditional endoscope is transformed as follows:

[0038] 1. Appropriately enlarge the caliber of the permanent mirror body pipe 11 in the endoscope body, so that the disposable pipe 3 that can be inserted into the disposable sheath can match the required caliber. This point will leave more and more space for the enlargement of the aperture due to the increasingly compressed image beam diameter or the smaller CCD.

[0039] 2. The water injection and gas injection pipeline in the endoscope mirror body is canceled, and only a mirror body water injection gas injection outlet 13 is established at the mirror body rear portion.

[0040] 3. A section of the endoscope front end is made into an endoscope round table 23, and the round table rear portion 18 of the round table 23 is elastically fitted with the boss 19 insi...

Abstract

The present invention relates to a endoscope system with disposable sheath, and using method. This system is composed of endoscope which can be used for time after time and disposable sheath which forms by the disposable pipe inner the sheath combining with the external cuff through the front cuff end-cap, and posting the proximal part of the disposable pipe after passing through the lens body pipe into the springy airproof cap by guide tube, then the hot-seal clamp weld and cut on the transaction of the disposable pipe and make the orifice form V font. In order to solve the medical source intercross infection of the endoscope on clinic, this invention provides disposable sheath which protects the endoscope from the internal surface of the operation hole pipe to the external surface omnidirectionally, and make the disposable pipe exit from the permanent lens body pipe without pollute the lens body pipe.

Description

technical field [0001] The present invention is an improvement to medical endoscope technology, specifically an endoscope system with a disposable sheath and its use method, which can solve the problem of iatrogenic cross-infection that can occur in clinical practice. The invention belongs to the technical field of medical equipment and is suitable for clinical promotion in hospitals. Background technique [0002] Due to its unique advantages such as intuitiveness, reliability of sampling and diagnosis, and minimally invasive surgery, medical endoscope has become an irreplaceable technology in various means of modern medicine. However, the problem of iatrogenic cross-infection that can occur in the application of medical endoscopes cannot be ignored. Especially the possibility of accidents such as hepatitis and AIDS virus that can be transmitted through blood and body fluids is even more daunting! In modern times, many medical devices have been changed to one-time use as m...
