Background

The development of modern electronic technology and modern optical technology and the revolutionary change of gynecological diagnosis and treatment modes lead the original open and invasive gynecological diagnosis and treatment to be replaced by endoscopic surgery and minimally invasive methods more and more, thus forming a new subject. With the rapid development of modern society and the accelerated pace of life, the psychological pressure born by people is heat preserving and heat preserving, which particularly affects the physical and mental health of women, especially the troubles caused by gynecological diseases. The traditional biomedical mode of society is changing into the biological-psychological-social medical mode nowadays, and psychosomatic medicine is the field of paying attention to gynecology, and has important meaning for promoting psychosomatic health. The gynecological endoscope is used clinically firstly, is the main means for diagnosing and treating uterine cavity diseases, and is used for treating diseases such as intrauterine adhesion, hysterosubmucosal myoma, intrauterine device abnormality, uterine malformation, endometrial polyp and the like. Some hysteroscope configurations are also disclosed in the prior art literature. As in the Chinese patent: the hysteroscope (CN 201624630U) comprises a connector, an outer tube is arranged at the front end of the connector, an optical fiber is arranged in the outer tube, the distance D between the optical fiber and the inner wall of the outer tube is 1.5-3.5 mm, a lens connecting tube is arranged at the rear end of the connector, a first water valve and a second water valve are respectively arranged at the left side and the right side of the connector, an operating tube is arranged at the upper part of the connector, and a light source connecting tube is arranged at the lower part of the connector. As in the Chinese patent: the endoscope comprises an endoscope body, a light guide bundle socket and an eyepiece cover, an optical lens system is arranged in the endoscope body, and the obturator is composed of an obturator handle and an obturator rod. However, the existing hysteroscope has a complex structure and is not very convenient to operate.

Disclosure of Invention

The utility model provides the hysteroscope which has the advantages of simple structure, wide visual field range, reduced operation risk and convenient operation; the hysteroscope solves the technical problems of complex structure, inconvenient operation and small visual field range of the hysteroscope in the prior art.

The technical problem of the utility model is solved by the following technical scheme: an electronic bent hysteroscope comprises a scope body, wherein one end of the scope body is connected with a handheld part, the other end of the scope body is connected with a scope tube, and a uterine plug part which can slide along the scope tube is sleeved on the scope tube; the front end of the mirror tube is provided with a section of bent tube insertion part, the front end of the bent tube insertion part is a front end part, and an image sensor is arranged on the front end part. The tip of mirror pipe is the straight tube, installs image sensor on the tip earlier, can realize shooing in real time and record a video, compares traditional optical lens, and the quality is more reliable, and it is more convenient to operate. Thereby the diameter of the lens tube is thinner, the infusion channel is bigger, and the washing is smoother. The rear side of the front end part is provided with a section of bent pipe insertion part, so that when the endoscope pipe is rotated, the field of view is enlarged, the bent pipe structure is more in line with human engineering, the surgical risk is reduced, and the diagnosis and treatment accuracy of doctors is improved. The uterine plug part can play a supporting role in positioning the insertion depth and performing surgical examination, and the operation convenience and safety of the operation are improved.

Preferably, the bending angle of the bent pipe is 15-45 degrees. The bent pipe is a hard pipe, and the angle of the bent pipe is convenient to insert and observe.

Preferably, an instrument channel, a transfusion channel and an image channel are arranged in the endoscope tube, and a light beam channel is arranged among the instrument channel, the transfusion channel and the image channel. The space is reasonably utilized, and the reasonable position arrangement of each channel is ensured under the condition that the endoscope tube is thinnest. The infusion channel can be filled or drained with liquid.

Preferably, the left side and the right side of the endoscope body are respectively provided with an infusion inlet, and an instrument inlet is arranged above the endoscope body. The infusion inlet is connected with the infusion channel, and the appliance inlet is connected with the appliance channel. The instrument inlet has opening and closing functions, is normally in a closed state, prevents liquid from being sprayed out in a backflow mode, and can be inserted into an instrument for operation and biopsy when the instrument inlet is opened.

Preferably, one end of the hand-held part is connected with the mirror body through a connecting pipe, and the other end of the hand-held part is externally connected with a power line and a light guide beam through a plug connecting part. Simple structure, pencil is few.

Preferably, the hand-held part is provided with a shooting button, a video recording button and a white balance button. White balance, photographing and video recording functions can be respectively carried out through the three buttons, the filing is more convenient, and the data are more sufficient and complete.

Preferably, one end of the uterine cavity portion is conical, the other end of the uterine cavity portion is circular, a conical guide connecting portion is arranged at the end of the endoscope body, the guide connecting portion is matched with one circular end of the uterine cavity portion, and an operating piece is externally connected to the uterine cavity portion. The uterine plug part can slide back and forth on the insertion part tube, and plays a supporting role in positioning the insertion depth and carrying out surgical examination.

Therefore, the hysteroscope of the utility model has the following advantages: the bent tube electronic hysteroscope has the advantage of being independently used as an examination mirror and a simple operation mirror. The head part adopts the electronic image sensor, the mirror body bends forwards and then forms a 22-degree angle, the human engineering principle is better met, the quality of the mirror is effectively improved, the mirror is not easy to be damaged by external force factors, the image is more visual, real-time photographing and video recording can be carried out, and the operation is more systematic and more convenient; the mirror body is smaller, the infusion channel is larger, and the washing is smoother.
