Problems solved by technology

These endoscopes are all precision optical instruments with complex structures and high prices, so protection is very important
In addition, because the endoscope is equipped with optical components at the front end, it is a rigid structure, which will cause discomfort to the human body when entering the human cavity, such as colonoscopy for patients with anal or intestinal stenosis
Since the same endoscope needs to be applied to different patients, most endoscopes are equipped with precision equipment such as optics and electronics, which cannot be sterilized by high temperature and high pressure. How to quickly disinfect and sterilize after each use to prevent Cross-infection becomes one of the problems

Embodiment 1

[0031] Such as figure 1 As shown, a multi-chamber endoscope sheath with a balloon according to the present invention, the endoscope includes an endoscope body that enters the human body, and the sheath 1 is provided with an endoscope that accommodates the endoscope body that enters the human body. Mirror channel 2, the endoscope channel 2 makes the main body of the endoscope enter the human body without direct contact with the human body. At the same time, the sheath 1 is detachably connected to the endoscope, which can be designed as a column or endoscope according to clinical needs and the shape of the endoscope. Arc, can be reusable or single use.

[0032] refer to figure 2 , the sheath 1 is also provided with a channel 3 for entering and exiting liquid or gas and an instrument channel 4. The instrument channel 4 can be connected to various medical instruments to perform minimally invasive operations on the human body. The number and position can be set according to needs...

Embodiment 2

[0036] This embodiment is roughly the same as Embodiment 1, the difference is that:

[0037] The balloon 6 of the balloon device is fixed on the patient end of the sheath 1 or the main body of the anorectoscope, and a pipeline 7 for injecting gas or liquid into the balloon 6 is arranged between the balloon device and the sheath 1 . When in use, liquid or gas can be injected into the balloon 6 through the pipeline 7 to expand the balloon 6, and the injected liquid or gas can be discharged when the balloon 6 is not in use.

[0038] image 3 It is a structural schematic diagram of an unexpanded balloon, and the pipeline 7 is located in the sheath 1 .

[0039] Figure 4 It is a schematic diagram of the first expansion method of the balloon. The front end of the balloon 6 is provided with a protrusion 9, and the protrusion 9 can expand the human cavity to facilitate entry, and the elasticity of the balloon 6 can reduce the discomfort caused when entering the human body.

Abstract

The invention discloses a protecting bush for a multiple-cavity endoscope with a balloon. The endoscope comprises an endoscope body entering the human body, wherein the protecting bushing is provided with an endoscope channel which accommodates the endoscope body entering the human body, a patient end of the protecting bush is provided with an instrument channel, and the protecting bush is detachably connected with the endoscope. The protecting bush provided by the invention can be repeatedly utilized and sterilized, and can be disposably used; furthermore, the front end of the protecting bush is provided with a balloon device, the balloon can be expanded by injecting liquid or gas into the balloon when the protecting bush is in use, a balloon structure formed at the front end of the protecting bush plays a role in expanding the cavity of the human body so that the endoscope can conveniently enter the human body, and the discomfort can be reduced by the elasticity of the balloon when the endoscope enters the human body; in addition, the expanded balloon can implement the functions of expanding the cavity, perform hemostasis by compression on a hemorrhagic spot, manometry and other functions in clinical application, and the injected liquid or gas can be drained when the balloon is not needed to be used.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multi-chamber endoscope sheath with a balloon. Background technique [0002] At present, in the field of medical operation or diagnosis application, minimally invasive surgical treatment or diagnosis technology under endoscopic observation has been more and more widely used. [0003] A medical endoscope is a tubular medical device equipped with a light source, which can enter the human body through the natural orifice of the human body, or through a small incision made by surgery, for visual inspection and treatment. The development of medical endoscopic technology has greatly improved the accuracy of diagnosis and the effectiveness of treatment. [0004] According to its development and imaging structure, medical endoscopes can be roughly divided into three categories: rigid tube endoscopes, optical fiber (hose type) endoscopes and electronic endoscopes. These en...
