Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a novel inflatable rectosigmoidoscope. Background Art

[0002] Sigmoidoscopy is a method of diagnosing rectal and sigmoid colon diseases with the help of a sigmoidoscope. The morphology of the rectal and sigmoid colon mucosa can be directly observed through a sigmoidoscope, and a biopsy can be performed.

[0003] Currently, most of the existing endoscopes are for dilated rectal observation or are simplified versions based on existing fiber endoscopes. They have some disadvantages: 1. Patients need to take laxatives in advance for intestinal preparation, and the patient is very uncomfortable during the operation; 2. The dilatation arm of the dilatation type may cover part of the rectal mucosa and affect the examination results, and the sigmoid colon part with a high incidence of lesions cannot be observed; 3. The fixed-position lens and lighting are used, and the captured image is a low-pixel image, which cannot provide a basis for subsequent three-dimensional image reconstruction. It is necessary to insert the endoscope multiple times to perform multiple examinations at the same time, which is cumbersome to operate and has poor scalability. Summary of the invention

[0004] The purpose of the present invention is to provide a novel inflatable rectosigmoidoscope to solve the problems that the existing endoscope preparation procedures are cumbersome, part of the rectal mucosa is easily covered during use and affects the examination, and the fixed position lens and lighting cannot meet the subsequent three-dimensional reconstruction of the image.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A novel inflatable rectosigmoidoscope comprises an outer transparent hose, a guide tongue is arranged at the top end of the outer transparent hose, a hand-held sleeve is arranged at one end of the outer transparent hose away from the guide tongue, a retaining ring is arranged at one end of the hand-held sleeve, an internally threaded hose is arranged inside the outer transparent hose, a shooting component is threadedly connected to the internally threaded hose, the shooting component is arranged at the top end of the auxiliary adjustment hose, the auxiliary adjustment hose is sleeved on the internally threaded hose, a closed cavity is formed between the outer transparent hose and the internally threaded hose, and an inflation port is arranged at the bottom end of the outer transparent hose, and the inflation port is communicated with the cavity.

[0007] Optionally, the outer transparent hose and the inner threaded hose are both hollow tubes and are on the same center line.

[0008] Optionally, the shooting assembly includes a mounting platform, the mounting platform is threadedly connected and sleeved on the internally threaded hose, and a camera and a lighting lamp are respectively arranged on the mounting platform.

[0009] Optionally, the hand-held cover and the retaining ring are made of hard plastic, and the hand-held cover and the retaining ring are detachably arranged on the outer transparent hose.

[0010] Optionally, a sealing ring is provided at the connection between the auxiliary regulating hose and the outer transparent hose to ensure the sealing of the cavity.

[0011] The beneficial effects of the present invention are as follows: an outer transparent hose is provided to cooperate with a guide tongue, a hand-held sleeve, and a retaining ring to facilitate operation to enter the patient's body; at the same time, an inner threaded hose is used to cooperate with a shooting component and an auxiliary adjustment hose to facilitate rotation and lifting to adjust the working position of the shooting component, so as to achieve a standard spiral upward mode of photographing, with high image quality and standardized shooting methods, which can provide a basis for subsequent three-dimensional image reconstruction, and change the traditional expansion setting to avoid the expansion arm covering part of the rectal mucosa. The outer transparent hose is expanded after inflation, so that the intestinal wall can be stretched to facilitate observation of the mucosa. For lesions in some folds, the intestine can continue to be inflated through the inner opening of the inner threaded hose to further expose the lesions, facilitate observation, and ensure smooth sigmoidoscopy.

[0026] like Figure 1-8A novel inflatable rectosigmoidoscope is shown, comprising an outer transparent hose 1, a guide tongue 2 is arranged at the top of the outer transparent hose 1, a hand-held sleeve 3 is arranged at one end of the outer transparent hose 1 away from the guide tongue 2, a retaining ring 4 is arranged at one end of the hand-held sleeve 3, an inner threaded hose 5 is arranged inside the outer transparent hose 1, a shooting assembly is arranged on the inner threaded hose 5 in threaded connection, the shooting assembly is arranged at the top of the auxiliary adjustment hose 9, the auxiliary adjustment hose 9 is sleeved on the inner threaded hose 5, a closed cavity is formed between the outer transparent hose 1 and the inner threaded hose 5, and an inflation port 10 is arranged at the bottom of the outer transparent hose 1, and the inflation port 10 is communicated with the cavity. It should be noted that the shooting assembly can achieve the standard spiral upward mode photography through the inner threaded hose 5 and the auxiliary adjustment hose 9 according to the needs, and the inflation port 10 makes the outer wall of the outer transparent hose 1 expand when inflating to achieve the effect of positioning the colonoscope, the end of the outer transparent hose 1, that is, the rectal part, is a hard transparent tube, and the other parts are soft transparent tubes.

[0027] Specifically, the outer transparent hose 1 and the inner thread hose 5 are both hollow tubes and are on the same center line. It should be noted that the inner thread hose 5 can be used to place endoscope auxiliary tools such as a water spray pipe, a water pump, etc., extending from the guide tongue 2 at the head end of the outer transparent hose 1.

[0028] Specifically, the shooting assembly includes a mounting platform 6, which is threadedly connected and sleeved on the internal thread hose 5, and a camera 7 and a lighting lamp 8 are respectively arranged on the mounting platform 6. It should be noted that the camera 7 is a wireless micro camera, and the lighting lamp 8 is a wireless micro lighting lamp.

[0029] Specifically, the hand-held cover 3 and the retaining ring 4 are made of hard plastic, and the hand-held cover 3 and the retaining ring 4 are both detachably arranged on the outer transparent hose 1. It should be noted that the hand-held cover 3 and the retaining ring 4 are detachably arranged on the outer transparent hose 1 through threaded connection, which is convenient for replacement and installation according to needs.

[0030] Specifically, a sealing ring is provided at the connection between the auxiliary adjustment hose 9 and the outer transparent hose 1 to ensure the sealing of the cavity. It should be noted that the sealing ring is provided with multiple layers.

[0031] The working principle of this specific embodiment is: firstly, the mounting platform 6 and the auxiliary adjustment hose 9 are mounted on the internal thread hose 5, and then the hand-held sleeve 3 is manually held to insert the outer transparent hose 1 into the patient's anus and into the intestine;

[0032] When the outer transparent hose 1 enters the rectum and the guiding tongue 2 reaches the top of the rectum, the process can be judged by hand feeling, insertion length and camera image, and the cavity between the outer transparent hose 1 and the inner threaded hose 5 is inflated through the inflation port 10, so that the outer transparent hose 1 is further extended, and the guiding tongue 2 guides during the process to ensure smooth entry;

[0033] The angle between the extended part of the outer transparent hose 1 and the inner tube of the rectum is flexible and variable and is close to 120°-160° with the angle between the sigmoid colon and the rectum in the natural state of the human body. Then, the auxiliary adjustment hose 9 is rotated and adjusted according to the needs to adjust the working position of the camera 7. During the above process, the camera 7 will take pictures in a standard spiral upward mode to obtain a complete image of the inner wall mucosa of the intestinal segment and display it in real time on the screen;

[0034] At the same time, a variety of small devices, such as ultrasound equipment, can be connected in series on the internal threaded hose 5. Note: when using an ultrasound probe, the tube is filled with water instead of air. The internal threaded hose 5 is also open at both ends, and can be used with a variety of current endoscope auxiliary tools. For example, a water spray tube can be inserted to perform and dye the intestinal cavity.

[0035] When the examination is completed, the inflation port 10 is deflated so that the outer transparent hose 1 can be smoothly withdrawn from the patient's body.

[0036] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
