Abstract
The utility model discloses a transparent cap of front end wave shape scope, including transparent cap body, transparent cap body adopts the clear glass material, and the one end of transparent cap body sets up the wave terminal surface, the wave terminal surface comprises a plurality of streamlined archs and recess. The utility model is used for during minimal access surgery under the scope, the target vein is fixed more easily, makes the injection more accurate and inject into intravenous medicine easily by keeping somewhere, treatment is better. The transparent cap can also be used for pressing the needle hole at the injection point, so that the local part is not easy to generate needle hole bleeding after injection.
Description
Technical Field
The utility model relates to a medical instrument for endoscope examination, in particular to a front-end wave-shaped endoscope transparent cap.
Background
With the development of endoscopic techniques and other techniques, the endoscopic injection of sclerosing agents has been more and more widely developed as an endoscopic minimally invasive technique for treating esophageal varices and hemorrhoidal veins. After injecting the hardening agent under the endoscope, the vein forms thrombus and secondary fibrosis, and has good effects of stopping bleeding and preventing rebleeding. However, the injection under the endoscope can not fix the injection target in the injection process of in vitro injection. The injection needle and the injection target under the gastroscope are often deviated along with the peristalsis of the alimentary canal, respiration and slight position change when an operator operates the endoscope.
Therefore, if a device can be added to the inner lens end to relatively limit the moving amplitude of the target vein, the accuracy of the endoscopic injection operation can be greatly improved. In another endoscopic procedure, early tumor removal, a cylindrical transparent cap is often attached to the inner lens end to help adjust the position of the target tissue. But the head end of the common transparent cap is flat and is not useful for fixing blood vessels. Therefore, it is necessary to invent a device capable of limiting the position of blood vessels under an endoscope.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a transparent cap of front end wave shape scope to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a transparent cap of front end wave shape scope, includes transparent cap body, transparent cap body adopts transparent glass material, and the one end of transparent cap body sets up the wave terminal surface, the wave terminal surface comprises a plurality of streamlined archs and recess.
As a further aspect of the present invention: the other end of the transparent cap body is provided with a connecting sleeve.
As a further aspect of the present invention: the connecting sleeve is made of elastic rubber.
As a further aspect of the present invention: the transparent cap body is also provided with a small hole.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model is used for during minimal access surgery under the scope, the target vein is fixed more easily, makes the injection more accurate and inject into intravenous medicine easily by keeping somewhere, treatment is better. The transparent cap can also be used for pressing the needle hole at the injection point, so that the local part is not easy to generate needle hole bleeding after injection.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In a first embodiment, please refer to fig. 1, in an embodiment of the present invention, a front-end wave-shaped endoscope transparent cap, includes a transparent cap body 1, the transparent cap body 1 is made of transparent glass, one end of the transparent cap body 1 is provided with a wave-shaped end surface 11, the wave-shaped end surface 11 is composed of a plurality of streamline bulges and grooves, and the bulge and groove model curve is a cosine curve: and y is acos (bx) and forms a wave shape, the other end of the transparent cap body 1 is provided with a connecting sleeve 12, and the connecting sleeve 12 is made of elastic rubber and the like and is used for connecting the tail end of the endoscope.
Fig. 2 is a schematic view of the visual field of the endoscope observation when the transparent cover is arranged at the end of the endoscope, in the figure, the inner area 15 is a straight visual area, the outer area 13 is a visual field observed through the transparent cap, the depressed area formed by the wavy end surface 11 has a positioning effect on the target vein and the like, the position change of the target vein and the like is limited, the edge line 14 formed by the edge of the wavy end surface 14 is arranged in the middle, the edge line 14 has a positioning effect when the endoscope is observed, the target vein under the endoscope can be assisted and fixed, and the treatment such as injection under the endoscope is more accurate.
In the second embodiment, referring to fig. 3, in this embodiment, one end of the transparent cap body 1 is provided with a wavy end surface 11, the other end is provided with a connecting sleeve 12, and the transparent cap body 1 is further provided with a small hole 16 for suction or irrigation under an endoscope.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
