Description

Endoscope system

Technical Field

The utility model relates to the field of medical equipment, particularly, relate to an endoscope system.

Background

The use of endoscopes for medical diagnosis has been widely used in the medical field. The endoscope can conveniently inspect the internal structure of the cavity through the narrow natural cavity of the human body, is an important means for diagnosis, and can also carry out fine treatment on the cavity through matched surgical instruments, so that the operation can reach the area which can not be reached by the traditional operation. For example, in the diagnosis of diseases related to otorhinolaryngology, it is necessary to insert the tube of an endoscope into the otorhinolaryngology or uterine cavity of a patient for examination, or even to perform surgical treatment under the endoscope.

The existing endoscope system has the following defects in use through research and discovery:

is limited by the design of the prior hard tube optical lens, has higher cost and can not be popularized and used for one time. The existing hard tube endoscope used repeatedly has the risk of potential cross infection caused by incomplete disinfection in the clinical use process. During operation, instruments extending into the endoscope for sampling or treatment are easy to interfere with each other, the operation is inconvenient, and the situation of the operated instruments cannot be observed in real time when the instruments pass through a narrow channel such as a sinus orifice, and the instruments are basically in a state of full-blind operation or semi-blind operation. In some application scenarios, different angles of access of the scope are required to view, for example, different angles of the ostium and the uterine horn. It is costly and resource-wasting for the patient if an endoscope is needed for each different angle of the endoscope. For the current hard tube endoscope used clinically, the angle can not be adjusted, if the structure with the angle adjustable front end is a snake bone structure, the diameter can be increased greatly, the cost can be increased correspondingly and the product reliability can be reduced correspondingly on the basis of the same other accessories.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an adjustable hard tube electronic endoscope system of front end angle, the operator is through the angle of adjusting the electronic endoscope front end, realizes that a section scope can carry out the angle modulation to the needs of different angles to solve the problem that endoscope and apparatus interfered with each other.

The embodiment of the utility model is realized like this:

in one aspect of the present application, there is provided an endoscope system comprising: the electronic hard tube endoscope comprises an endoscope body, a packaging head end and a handle; the handle is formed at one side end of the mirror body, and the packaging head end is arranged at the front end of the mirror body; the lens body comprises a bendable outer tube and a camera module; the camera module is arranged in the bendable outer pipe; the mirror body angle adjuster can adjust the angle of the bendable outer tube in vitro so as to realize the adjustment of the angle of the electronic hard tube mirror body.

In some embodiments, the scope includes an instrument lumen and/or a water injection lumen and an LED module disposed within the bendable outer tube.

In some embodiments, the bendable outer tube is made of a bendable shaped metal tube, a plastic tube, or a braided tube.

In some embodiments, the bendable metal tube is made of stainless steel.

In some embodiments, the package head end includes one or more of a camera package port, an instrument lumen opening, an LED package port, and a water injection lumen opening.

In some embodiments, the front end of the LED package opening of the package head end is a convex lens design.

In some embodiments, the tail of the instrument cavity is connected with an instrument cavity tail end connector, the instrument cavity tail end connector is connected with a two-way connector interface, and the two-way connector interface is connected with a two-way valve.

The embodiment of the utility model provides a beneficial effect is:

the application provides a disposable hard tube endoscope system with an adjustable angle, which can adopt an inexpensive electronic camera and solve the problems that the existing hard tube optical lens is high in cost and cannot be popularized to be used once. Of course, a simple hard tube electronic endoscope of this application can be recycled, cleaned and sterilized. The simple hard tube electronic endoscope is disposable, and the risk that potential cross infection is caused by incomplete disinfection in the clinical use process of the existing reusable hard tube endoscope is solved. Because the operation instrument enters through the instrument cavity of the endoscope, and the relative position of the instrument and the endoscope is fixed after the instrument exits from the cavity, the problems that the instrument which is extended into the endoscope under the visual field of the endoscope for sampling or treatment is easy to interfere with each other during operation, the operation is inconvenient, and the condition of the operation instrument cannot be observed in real time when the operation instrument passes through a narrow channel such as a sinus orifice, and the operation instrument is basically in a full-blind operation state or a semi-blind operation state are solved. Under some application scenarios, hard tube endoscopes at different angles are required to enter so as to observe sinus ostia and uterine horns at different angles, and for patients, if an endoscope at each different angle is required, the cost is high and resources are wasted. The disposable hard tube endoscope with the adjustable angle solves the problem of the bend angle. For the current hard tube endoscope used clinically, the angle can not be adjusted, if the structure with the angle adjustable front end is a snake bone structure, the diameter can be increased greatly, the cost can be increased correspondingly and the product reliability can be reduced correspondingly on the basis of the same other accessories. The disposable angle-adjustable hard tube endoscope can reduce the outer diameter of the endoscope body as much as possible on the basis of accessories with the same size, and meanwhile, the reliability of products is guaranteed.
