Description

Disposable medical endoscope sheath

Technical Field

The utility model belongs to the technical field of endoscope sheaths, and particularly relates to a disposable medical endoscope sheath.

Background

At present, the electronic endoscope is widely applied to the fields of examination, diagnosis, treatment and the like of human cavity parts such as alimentary tracts, ears, noses and throats. Because the medical endoscope is used deep into the human body, the medical endoscope inevitably needs to be contacted with body fluid, blood and the like, and if the medical endoscope is not thoroughly disinfected and sterilized, cross infection and other difficult-to-measure results are generated.

On one hand, the service life of the endoscope is shortened due to disinfection and sterilization; on the other hand, the electronic endoscope cannot be popularized and used because the sterilization requirement is too high and the general hospitals do not have sterilization conditions.

Endoscopes are generally classified into endoscopes for observation, diagnosis and treatment including a working channel, and endoscopes for observation, diagnosis excluding a working channel. The endoscope having the working channel is complicated in structure and high in cost.

The traditional endoscope sheath only plays a part of protection role on the endoscope, and cannot solve the problems of sterilization and function sharing of the endoscope.

CN102038479B still connects together working channel, aqueous vapor connector and the handle of endoscope, can not realize working channel, aqueous vapor channel and the complete separation of mirror body, still has the risk of pollution.

CN103584827B, an endoscope sheath is specially arranged in the whole sheath, and the water-gas channel uses an irregular space formed by the outer wall of the sheath, the endoscope sheath and the working channel. Because the endoscope sheath is completely closed except the endoscope inlet, air resistance is formed when the endoscope is inserted, friction force between the endoscope and the sheath wall is superposed, and the endoscope is difficult to insert; in addition, in order to control the outer diameter size of the whole sheath, the wall thickness of the general endoscope sheath is thinner, once the endoscope is inserted, the endoscope sheath is broken because of carelessness, and the endoscope sheath is broken and is not easy to find because of the existence of the outer wall of the sheath, so that the risk of pollution exists. The wedge-shaped joint needs to be matched with a specific endoscope handle for use, and has low applicability.

Therefore, there is a need for an improved medical endoscope sheath that increases the stability of sterilization and reduces the probability of cross-infection. Meanwhile, the functions of the endoscope are expanded, observed and diagnosed through the endoscope sheath, and a working pore canal is increased for treatment.

Disclosure of Invention

Aiming at the technical problems that the traditional endoscope sheath only plays a part of protection role on the endoscope and cannot solve the sterilization and function sharing of the endoscope, the utility model provides a disposable sheath which is simple and convenient to operate, can avoid the pollution of the endoscope body, is matched with the medical endoscope for use, and simultaneously expands the functions of the observation and diagnosis type endoscope.

The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

In this embodiment, as shown in fig. 1, the endoscope sheath 1 has a certain elasticity, and the inner surface has a hydrophilic fluororesin coating; the water gas channel 201 and the tool channel 202 are parallelly wrapped inside the endoscope sheath 1; the elastic sleeve 3 has larger elasticity and is jointed with the tail part of the endoscope sheath 1 to fix the endoscope sheath 1 on the endoscope handle; the lens mechanism 4 is made of hard and transparent materials, is fixed on the head of the endoscope sheath 1, is communicated with the water gas channel 201 and the tool channel 202, the water gas channel 201 is sleeved on a water gas channel hole 401 reserved in the lens mechanism 4, and the tool channel 202 is embedded on a tool channel hole 402 reserved in the lens mechanism 4. Another simple version eliminates the tool channel 202 and the tool channel aperture 402 of the lens mechanism 4, leaving only the moisture channel 201 and the moisture channel aperture 401 of the lens mechanism 4. The water gas channel 201 and the tool channel 202 are all communicated with the outside through the opening at the front end of the lens mechanism 4, and the inside of the endoscope sheath 1 is a closed space except the opening at the tail of the elastic sleeve 3. As shown in fig. 2, a gap 102 is still reserved on the side surface of the endoscope body 101 when the endoscope body 101 is inserted into the endoscope sheath 1, so that exhaust gas is conveniently inserted, and the use difficulty is reduced.

When the actual endoscope is used, the endoscope body 101 is inserted from the opening of the elastic sleeve bag 3, the lens structure of the endoscope is inserted into the upper lens mechanism 4 through the sheath, and the elastic sleeve bag 3 tightens and fixes the whole endoscope sheath 1 on the handle of the endoscope, so that the whole endoscope is isolated from the outside; after each use, only the whole sheath needs to be replaced.

Whether the endoscope is provided with the water vapor channel 201 and the tool channel 202 or not, the endoscope is provided with the water vapor channel and the tool channel and has the functions of examination, diagnosis and treatment when being matched with the sheath.

When only the examination and diagnosis are needed by the endoscope, the simple endoscope sheath without the tool channel 202 can be selected, so that the cost is reduced on one hand, the external diameter of the part inserted into the body is reduced on the other hand, and the insertion is convenient.

The preferred embodiments of the present utility model have been described in detail, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model, and the various changes are included in the scope of the present utility model.
