Description

Insertion structure of integrated surgical endoscope

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to an integral type surgical endoscope's insertion structure is related to.

Background

A conventional hysteroscopic surgical instrument generally includes an endoscope, a sheath, an obturator and other main operating instrument components in a handheld operating part, and the sheath usually consists of an inner sheath and an outer sheath. Sterilization is required between different procedures. And each standard disinfection operation needs to be carried out on the disassembly of the instruments so as to carry out comprehensive disinfection operation. When the endoscope is disassembled, the diameter of the insertion part is thin, the strength of the endoscope is low, the endoscope is extremely easy to damage in the normal disassembling, sterilizing and installing processes, the disassembling of the instrument can also increase the training and operating difficulty of medical staff, and the working time of the medical staff is increased. The problem to be solved is particularly urgent, as the more compact structure makes the product more lightweight, especially how to make the product more slim at the insertion end. Because the inserted part direct action is human, all need pass through the human body when inserting like hysteroscopic operation, especially when passing through the uterus, because human uterus is natural pore, product size is invariable, and smaller product has littleer influence, otherwise the product is bigger more can cause bigger wound to the people more, need expand the uterus even and just can perform the operation, the painful and postoperative infected risk that makes the operation bring can great increase like this. The significance of how to make the product more compact is particularly important.

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-6, an insertion structure of an integrated surgical endoscope comprises an outer sheath tube 1, a liquid injection channel special tube 2, an illumination optical fiber tube 3 and an optical lens circular tube 4 which are sequentially arranged from outside to inside, wherein the liquid injection channel special tube 2 is convex upwards and concave downwards and is in a bridge-shaped structure, one side of the inner wall of the outer sheath tube 1 is close to and attached to one side of the upper part of the outer wall of the liquid injection channel special tube 2 to form a new irregular channel, the inner side of the concave surface at the lower end of the liquid injection channel special tube 2 is abutted to the illumination optical fiber tube 3 to enable the illumination optical fiber tube 3 to be clamped in the liquid injection channel special tube 2, the outer part of the liquid injection channel special tube 2 and the outer sheath tube 1 form a backflow channel 5, and water inlet channels 6 are formed between the two sides of the illumination optical fiber tube 3 and the liquid injection channel special.

The gap 7 between the illumination fiber tube 3 and the optical lens circular tube 4 is filled with an illumination fiber and a filling glue 8, and optical system parts such as an optical lens for transmitting an image, a metal spacer and the like are arranged in the optical lens circular tube 4, namely, the optical lens serves as an endoscope optical image transmission and observation part actually.

The longitudinal section of the gap between the illumination optical fiber tube 3 and the optical lens circular tube 4 is annular (the two tubes are concentric as shown in fig. 2-3) or crescent-shaped (the two tubes are eccentric as shown in fig. 1 and 4).

The head end side direction of the outer sheath pipe 1 is an acute angle upper side and an obtuse angle lower side inclined plane 10, the inclined plane 10 at the obtuse angle is a fillet or a chamfer angle with the outside, and the edges of the whole inclined plane 10, the end face and the outside are fillets. The fillet structure is convenient for reducing the injury to the human body when the operation is inserted. When performing an operation, because the one end of end is comparatively sharp, in order to avoid the point portion injury human body, often can oppress the end other end, the other end can form the oppression to the human body this moment, and the structure changes into breach formula fillet and then can form a fine buffering to the human body, avoids consequently receiving the injury.

The tail end of the outer sheath tube 1 is provided with a downward protruding structure 11, and the pipe diameter of the protruding structure 11 is larger than the pipe diameters of other parts of the outer sheath tube 1. The buffer device has the function of providing buffer for inserted instruments such as medical forceps and the like in instrument channels when the instruments pass through, so that the turning radius is larger when the instruments are inserted, and the instruments are inserted more smoothly. While the root of the insertion portion is provided with a circular configuration. The circular configuration facilitates easier machining of the body portion. Meanwhile, the outer sheath tubes with different specifications can be arranged to use the same circular structure, so that the processing is more uniform.

The side wall of the return channel 5 near the end is provided with a plurality of drain holes 9. The return channel 5 can both return the fluid and also feed surgical instruments.

When in use, as shown in fig. 7-10, the insertion structure, the bridge portion 13 and the endoscope portion 12 are sequentially assembled and fixedly connected to form an integrated surgical endoscope.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
