Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, in particular to an esophageal mucosa detector. BACKGROUND

[0002] The esophageal mucosa detector is a medical device for evaluating the health status of esophageal mucosa, and its detection purpose is to early detect lesions, determine disease nature, guide treatment plan development and monitor disease changes.

[0003] The patent with publication number CN205322285U discloses a capsule endoscope for examining esophageal diseases, which comprises a capsule shell, an imaging device, a control device, an air bag, and an inflation / deflation device and a pressure sensor connected with the air bag. The air bag is a transparent body and is arranged on the periphery of the capsule shell. The inflation / deflation device and the pressure sensor are both arranged in the capsule shell. The inflation / deflation device is used to drive the air bag to open or shrink, and the pressure sensor is used to measure the gas pressure in the air bag. The capsule endoscope for examining esophageal diseases provided by the patent can control the size of the air bag according to the esophageal wall pressure or peristaltic force, realize the full contact of the air bag with the esophageal wall, slow down the running speed of the capsule and expand the esophagus to facilitate the acquisition of esophageal wall images or videos, and can also implement treatment on the diseased part of the esophageal wall.

[0013] The covering assembly comprises a slide rod one fixedly connected to one side of the upper end of the scraping plate, and the slide rod one is slidingly connected with a cover plate.

[0014] Preferably, a threaded rod one is threadedly connected to one side of the cover plate, and one end of the threaded rod one is rotatably arranged on the scraping plate.

[0015] Preferably, a motor one is fixedly connected to one side of the upper end of the scraping plate, and the output end of the motor one is connected with one end of the threaded rod one.

[0020] The beneficial effects of the present application are as follows:

[0021] 1. The esophageal mucosa detector of the present application, by using the mucosa scraping assembly, can collect the esophageal mucosa of the patient for subsequent histopathological analysis, so as to facilitate the determination of key information such as cell type, differentiation degree, and atypia of the lesion, and then accurately judge whether the lesion is benign or malignant, and provide a basis for developing a treatment plan, avoiding the confusion that may occur when judging the nature of the lesion by naked eye. In addition, after the mucosa is scraped into the groove, the cover plate is driven to move along the surface of the scraper, covering the groove, and when the shell is removed, the shell is driven away from the groove, so that the esophageal mucosa is in a closed state before the shell is removed from the patient's esophagus, avoiding the situation that the mucosa in the groove is separated from the groove due to the shaking and deviation of the shell when the shell is removed from the patient's esophagus, further ensuring the normal collection of the esophageal mucosa.

[0022] 2. The esophageal mucosa detector of the present application, by using the removal auxiliary assembly, when the shell is removed from the patient's esophagus, the ball can first pass through the through hole two and contact with the inner wall of the esophagus, and then the shell is removed. Since the rolling contact mode of the ball is more easily removed from the esophagus than directly pulling the shell, the situation that the shell is stuck is avoided, thereby reducing the irritation and friction of the esophageal mucosa and reducing the discomfort of the patient.

[0023] 3. The esophageal mucosa detector of the present application can control the structure on the shell through the control key and the display screen, which is more convenient. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] Please refer to Figures 1-9 , the present application provides a technical scheme: an esophageal mucosa detector, comprising a handle 5, the upper end of the handle 5 is fixedly connected with an air pump 1, the air outlet end of the air pump 1 is communicated with an air pipe 2, one end of the air pipe 2 is communicated with an air cylinder 6, the lower end of the air cylinder 6 is fixedly connected with a shell 4, the upper end of the shell 4 is fixedly connected with an air bag 3, the air inlet of the air bag 3 is communicated with the air outlet of the air cylinder 6, and a mucosa scraping assembly is further arranged on the shell 4.

[0037] The mucosa scraping assembly comprises sliding rod two 19 fixedly connected to the inner cavities of the shell 4, the sliding rod two 19 is slidably connected with a support plate 10, the support plate 10 is inserted and slidably connected with a scraper 13 on both sides, and the shell 4 is further provided with through hole one 8 through which the scraper 13 passes.

[0038] In this embodiment, as shown in Figures 1-6 , Figure 9 , one side of the support plate 10 is threadedly connected with threaded rod two 20, both ends of the threaded rod two 20 are rotatably arranged on the inner wall of the shell 4, one side of the inner cavity of the shell 4 is fixedly connected with a motor two 21, and the output end of the motor two 21 is fixedly connected with one end of the threaded rod two 20.

[0039] The upper end surface of the scraper 13 is rotatably provided with a connecting rod one 12, and one end of the connecting rod one 12 is rotatably provided with a hinged block 18.

[0040] The support plate 10 is fixedly connected with an electric push rod 7 on one side, and the piston end of the electric push rod 7 is fixedly connected with one side of the hinged block 18.

[0041] The scraping plate 13 is provided with a groove 30 on one side, and the scraping plate 13 is further provided with a covering assembly.

[0042] The covering assembly comprises a sliding rod 17 fixedly connected to one side of the upper end of the scraping plate 13, and the sliding rod 17 is slidingly connected with a cover plate 14.

[0043] The cover plate 14 is threadedly connected with a threaded rod 16 on one side, and one end of the threaded rod 16 is rotatably arranged on the scraping plate 13.

[0044] The scraping plate 13 is fixedly connected with a motor 15 on one side of the upper end, and the output end of the motor 15 is connected with one end of the threaded rod 16.

[0045] Specifically, in the prior art, the morphology, color and integrity of the esophageal mucosa are directly observed through an endoscope to find lesions such as hyperemia, edema, erosion and ulcer. However, although endoscopic observation can directly show the changes in the morphology, color and the like of the esophageal mucosa, it is difficult to accurately determine the nature of the lesion by naked eye observation. For example, the endoscopic manifestations of early esophageal cancer can only be local color change, thickening or morphological change of the mucosa, which can be similar to the endoscopic manifestations of benign lesions such as esophagitis and esophageal polyps, and can be easily confused.

[0046] Therefore, in order to solve the above problems, in use, the air bag 3 in the initial state is in an uninflated state, and the scraping plate 13 is in the inner cavity of the shell 4. Then the patient can easily swallow the shell 4.

[0047] Then start the air pump 1, fill the air bag 3 with gas through the air pipe 2 and the air cylinder 6, so that the air bag 3 expands until it adheres to the inner wall of the patient's esophagus, at which time the position of the shell 4 is fixed. Then start the electric push rod 7, and the electric push rod 7 drives the hinged block 18 to move, so that the scraping plate 13 slides on the support plate 10 under the action of the connecting rod 12, and the scraping plate 13 adheres to the inner wall of the esophagus through the through hole 8, and then the motor 21 drives the threaded rod 20 to rotate, so that the support plate 10 slides on the sliding rod 19, and then the scraping plate 13 moves along the inner wall of the esophagus, so that the esophageal mucosa can be scraped, and the mucosa will be in the groove 30.

[0048] When the scraping plate 13 completes the scraping action, the electric push rod 7 is started again to retract the scraping plate 13 into the shell 4, and then the gas in the air bag 3 is released, at which time the shell 4 can be easily removed from the patient's esophagus. Then the scraped esophageal mucosa is subjected to histopathological analysis, so as to facilitate the determination of key information such as the cell type, differentiation degree and atypia of the lesion, and then the nature of the lesion is accurately determined, which provides a basis for formulating a treatment plan and avoids the confusion that can occur when the nature of the lesion is determined by naked eye observation.

[0049] In addition, when the shell 4 is taken out from the esophagus of the patient, the mucosa in the groove 30 can be detached from the groove 30 due to the shaking and deviation of the shell 4, thereby affecting the normal collection of the esophageal mucosa;

[0050] Therefore, in order to solve the above problems, when the mucosa is scraped into the groove 30, the motor 15 drives the threaded rod 16 to rotate, so that the cover plate 14 moves along the surface of the scraper 13 to cover the groove 30, and then the shell 4 is driven away from the groove 30 after the shell 4 is taken out, so that the esophageal mucosa is in a closed state before the shell 4 is taken out from the esophagus of the patient, thereby avoiding the situation that the mucosa in the groove 30 is detached from the groove 30 due to the shaking and deviation of the shell 4 when the shell 4 is taken out from the esophagus of the patient, and further ensuring the normal collection of the esophageal mucosa.

[0051] In the embodiment, as shown in Figure 4 , Figure 7 , Figure 8 shown, the shell 4 is further provided with a taking-out auxiliary assembly;

[0052] The taking-out auxiliary assembly comprises a plurality of sliding blocks 11 slidingly connected to the bottom of the inner cavity of the shell 4, one end of the sliding block 11 is rotatably provided with a ball 22, and the bottom of the shell 4 is provided with a plurality of through holes 29 through which the ball 22 passes.

[0053] One side of the upper end of the sliding block 11 is rotatably provided with a connecting rod 23, one end of the connecting rod 23 is rotatably provided with a threaded sleeve 24, the threaded sleeve 24 is threadedly connected with a threaded rod 26, both ends of the threaded rod 26 are rotatably provided on the inner wall of the shell 4, one side of the inner wall of the shell 4 is fixedly connected with a motor 25, and the output end of the motor 25 is fixedly connected with one end of the threaded rod 26.

[0054] Specifically, in the above embodiment, although the esophageal mucosa of the patient can be collected, since the esophagus is not straight but has a certain arc and physiological curved pipeline structure, when the shell 4 is taken out from the esophagus of the patient, the shell 4 is easy to be stuck in the esophagus, thereby increasing the discomfort of the patient;

[0055] Therefore, in order to solve the above problems, when the shell 4 is taken out from the esophagus of the patient, the motor 25 can first drive the threaded rod 26 to rotate, so that the threaded sleeve 24 moves, at the same time, the threaded sleeve 24 drives a plurality of connecting rods 23 to rotate at the same time, the connecting rod 23 drives the sliding block 11 to slide at the bottom of the shell 4, so that the ball 22 passes through the through hole 29 and contacts with the inner wall of the esophagus, and then the shell 4 is taken out. Since the rolling contact mode of the ball 22 is more easy to be taken out from the esophagus than directly pulling the shell 4, the situation that the shell 4 is stuck is avoided, thereby reducing the stimulation and friction of the esophageal mucosa and reducing the discomfort of the patient.

[0056] In this embodiment, as shown in Figure 1 The handle 5 is fixedly connected with a controller 27 on one side, and the controller 27 is provided with a display screen 29 and control buttons 28.

[0057] Specifically, the structure on the shell 4 can be controlled through the control buttons 28 in cooperation with the display screen 29, which is more convenient.

[0058] Working principle: the initial state of the air bag 3 is not inflated state, and the scraper 13 is in the inner cavity of the shell 4. Then the patient can easily swallow the shell 4. Then start the air pump 1, fill the air into the air bag 3 through the air pipe 2 and the air cylinder 6, so that the air bag 3 expands until the air bag 3 adheres to the inner wall of the patient's esophagus, at this time, the position of the shell 4 is fixed. Then start the electric push rod 7, the electric push rod 7 drives the hinge block 18 to move, that is, the scraper 13 can slide on the support plate 10 under the action of the connecting rod 12, and the scraper 13 passes through the through hole 8 and adheres to the inner wall of the esophagus, then the motor 21 drives the threaded rod 20 to rotate, so that the support plate 10 slides on the slide rod 19, then the scraper 13 moves along the inner wall of the esophagus, that is, the mucosa can be scraped, and the mucosa will be in the groove 30. When the scraper 13 completes the scraping action, start the electric push rod 7 again to make the scraper 13 retract into the shell 4, then release the gas in the air bag 3, at this time, the shell 4 can be easily removed from the patient's esophagus. Then the scraped esophageal mucosa is subjected to pathological histological analysis, so as to clearly determine the key information such as cell type, differentiation degree, and atypia of the lesion, and then accurately judge whether the lesion is benign or malignant, so as to provide basis for formulating treatment plan and avoid the confusion when judging the nature of the lesion by naked eye. In addition, when the shell 4 is taken out of the patient's esophagus, the mucosa in the groove 30 may be separated from the groove 30 due to the shaking and deviation of the shell 4, thereby affecting the normal collection of the esophageal mucosa. Therefore, in order to solve the above problem, after the mucosa is scraped into the groove 30, the motor 15 drives the threaded rod 16 to rotate, so that the cover plate 14 moves along the surface of the scraper 13 and covers the groove 30. When the shell 4 is taken out, the shell 4 is driven away from the groove 30, so that the esophageal mucosa is in a closed state before the shell 4 is taken out of the patient's esophagus, thereby avoiding the situation that the mucosa in the groove 30 is separated from the groove 30 due to the shaking and deviation of the shell 4 when the shell 4 is taken out of the patient's esophagus, and further ensuring the normal collection of the esophageal mucosa. When the shell 4 is taken out of the patient's esophagus, the motor 25 can be driven to rotate the threaded rod 26, so that the threaded sleeve 24 moves, and at the same time, the threaded sleeve 24 drives multiple connecting rods 23 to rotate at the same time, the connecting rods 23 drive the sliding block 11 to slide at the bottom of the shell 4, so that the ball 22 passes through the through hole 9 and contacts the inner wall of the esophagus, and then the shell 4 is taken out. Because the rolling contact mode of the ball 22 is more easy to take out than directly pulling the shell 4, the shell 4 is not easy to be stuck, thereby reducing the stimulation and friction of the esophageal mucosa and reducing the discomfort of the patient. The structure on the shell 4 can be controlled through the control button 28 and the display screen 29, which is more convenient.
