Abstract

The utility model relates to an observation mirror used for examining diseases of the rectosigmoid colon of a human body, which is composed of a mirror tube, a mirror tube base, an observation part, and a handle. The mirror tube is a multi-layer casing structure, which can be stretched and overlapped, and a light source is installed on the inner wall of the front end of the innermost layer of the casing. Depending on the condition, it is necessary to intubate different parts at one time under good light, thereby reducing the pain of the patient and improving the success rate of the inspection. The device is suitable for all levels of medical treatment and epidemic prevention units.

Description

Hand-hold telescoping recto-sigmoidoscope

The utility model relates to an apparatus for diagnosis of anorectal departments in hospitals and epidemic prevention units.

At present, it is still very common to use rigid tube sigmoidoscopy to check anorectal diseases at home and abroad. However, the illumination of the rigid tube microscope used is poor, the inspection is inconvenient to use, and the accuracy is low, and the length of the tube needs to be changed outside the body. This brings great misery to the patient and brings more chances of inspection failure to the doctor because of the intestinal tube spasm caused by repeated intubation.

The utility model aims at the deficiency of the above-mentioned existing inspection observation mirror, and provides an observation mirror which can improve the illuminance, is easy to use, and can complete the inspection by one-time intubation.

The utility model is described below in conjunction with accompanying drawing.

Accompanying drawing is the structural representation of observation mirror of the utility model. Among the figure, 1 is a mirror tube, 2 is a mirror tube base, 3 is an observation part, 4 is a handle, 5 is a lamp holder, 6 is a conductive wire, and 7 is a multifunctional connector.

In the present invention, the existing mirror tubes are changed from multiple interchangeable ones to a single mirror tube 1, and the single mirror tubes are combined into 4-5 section bushings according to different sizes and diameters of 18-26 mm, and the total length of the bushings can reach 350 millimeters, the sleeve pipe can be made of materials such as stainless steel, alloy; A lamp holder 5 is housed on the inner side wall of the innermost layer sleeve pipe front end simultaneously, can be used as near light source when checking. A spring-shaped conductive wire 6 is connected to the tail of the lamp holder 5, and the conductive wire 6 can expand and contract with the length of the mirror tube. After one intubation, if it is necessary to carry out a further bowel inspection, just push the cannula forward with the core, and there is no need to pull it out of the body to change the tube and then perform intubation inspection. In addition, between the mirror tube base 2 and the observation part 3, a free-rotating and sealable air-inflating, flushing, and suction multifunctional joint pipe 7 is installed, which is convenient for processing when there is dirt in the mirror tube during the inspection process, so as to continue Check. The connection between the handle 4 and the observation part 3 is separable, and the combination is through sliding groove anastomosis, which is easy to carry and disinfect; Tadpole shape larger than 18 mm and smaller than 20 mm; the multi-functional joint 7 is composed of inner and outer two-layer sleeves, with 2 catheter holes through the mirror tube cavity, and the outer layer can rotate to close the catheter holes, which are used for inflation and flushing , Attractive use.

The best embodiment of this instrument is made of stainless steel.

Compared with the prior art, the utility model has the advantages of only one intubation, less pain for patients, less chance of inspection failure, shorter inspection time, better light source, and more accurate inspection. The device is suitable for use in hospitals and epidemic prevention units at all levels.
