according to the mouth gag for gastroscopy shown in fig. 1-7, the tongue pressing mechanism assembly 14 comprises a second connecting rod 1401, wherein a transmission rod 9 is fixedly connected to the inner wall of the second connecting rod 1401, the second connecting rod 1401 forms a rotating structure through the transmission rod 9, a first conical gear 1402 is fixedly connected to the outer wall of the second connecting rod 1401, a second conical gear 1403 is connected to the outer wall of the first conical gear 1402 in a meshed manner, and a bearing rod 1404 is fixedly connected to the inner wall of the second conical gear 1403;
at this time, the motor 8 is started, the transmission rod 9 is driven to rotate by the motor 8, and as the first conical gear 1402 and the transmission rod 9 are fixedly connected to the inner wall of the second connecting rod 1401, the first conical gear 1402 rotates along with the transmission rod 9 by the second connecting rod 1401, and further drives the second conical gear 1403 which is in meshed connection with the outer wall of the first conical gear 1402 to rotate, and at this time, the bearing rod 1404 is driven to rotate by the second conical gear 1403, so that the mouth opening supporting mechanism assembly 11 supports the oral cavity of a patient and simultaneously finishes the capping of the tongue of the patient;
the bearing rod 1404 forms a rotating structure through the two conical gears 1403, the outer wall bearing of the bearing rod 1404 is connected with a fixed plate 16, the outer wall of the bearing rod 1404 is fixedly connected with a connecting plate 1405, and the other end of the connecting plate 1405 is fixedly connected with a tongue depressor 1406;
because the outer wall fixedly connected with connecting plate 1405 of shaft rod 1404, and then connecting plate 1405 drive tongue depressor 1406 to rotate, the tongue depressor 1406 is through connecting plate 1405 along shaft rod 1404 circular motion this moment, and then drives tongue depressor 1406 to gland the tongue in patient's oral cavity to solve the problem that patient's tongue stirs when carrying out gastroscopy, and then prevented that patient's tongue from stirring in the oral cavity, the condition that causes the gastroscopy pipe to take place to rock appears.
The implementation mode specifically comprises the following steps: the tongue pressing mechanism assembly 14 is driven to work through the transmission rod 9, so that the tongue pressing plate 1406 is subjected to angle adjustment to finish the gland of the tongue of a patient, the problem that the tongue of the patient is stirred when gastroscopy is carried out is solved, the tongue of the patient is further prevented from stirring in the oral cavity, the gastroscopy tube is prevented from shaking, the stability of the gastroscopy of the patient by medical staff is guaranteed, and the efficiency of the gastroscopy of the patient by the medical staff is improved.
The working principle of the invention is as follows: firstly, an inserting ring 4 is placed into a mouth of a patient, at the moment, a mask 1 is contacted with the mouth of the patient, then a hanging ring 2 is connected with the mask 1, then a binding belt 3 is pulled to the neck of the patient by pulling, the patient is helped to finish wearing a plate of a mouth supporting device, the patient bites a tooth sleeve 12, at the moment, a motor 8 is started, a transmission rod 9 is driven to rotate by the motor 8, and a first conical gear 1402 and the transmission rod 9 are fixedly connected to the inner wall of a second connecting rod 1401, so that the first conical gear 1402 rotates along with the transmission rod 9 by the second connecting rod 1401, and the tongue in the mouth of the patient is pressed by a tongue pressing plate 1406 by an inner part of a tongue pressing mechanism assembly 14, so that the problem that the tongue of the patient is stirred during gastroscopy is solved, the tongue of the patient is prevented from stirring in the mouth, and the condition that a gastroscopy tube shakes is caused;
when the transmission rod 9 rotates, the first gear 10 is fixedly connected to the outer wall of the transmission rod 9, so that the first gear 10 is driven to rotate, the first gear 10 drives the toothed ring 1101 which is in meshed connection with the outer wall to rotate, the toothed ring 1101 slides along the slideway 6 formed in the inner wall of the fixed ring 5, the second gear 1102 is meshed and connected with the inner wall of the toothed ring 1101, the second gear 1102 rotates along with the toothed ring 1101, the adsorption pad 1110 is driven to contact with four sides of the oral cavity of a patient through the internal part of the mouth supporting mechanism assembly 11, and limiting of the oral cavity of the patient is completed, so that the problem that the mouth of the patient needs to be opened for a long time and the support assistance of the oral cavity of the patient is lacked is solved, the condition that the mouth of the patient is opened for a long time, muscle strain of the oral cavity of the patient is caused is prevented, and muscle fatigue of the patient when the patient supports the mouth is reduced;
the second gear 1102 rotates, thereby drive the internal part of the spacing mechanism component 13 to carry out the work threaded rod 1301 through the dead lever 1103, drive the limiting plate 1304 together to slide through the mutual cooperation of the internal part of the spacing mechanism component 13, because the limiting plate 1304 is on same vertical line with the tooth socket 12, and then the limiting plate 1304 carries out now to the tooth of the interlock in the tooth socket 12, accomplish the fixing to patient's tooth, thereby the problem that current gastroscopy mouth gag needs patient to bite the mouth gag for a long time is solved, adopt spacing mode to help the patient to interlock, the fatigue degree that patient needs long time interlock has been reduced, finally pass through inserting ring 4 with the gastroscopy pipe in proper order, solid fixed ring 5, mouth gag mechanism component 11 and place ring 15 and reach the intestines and stomach department that patient needs to inspect, accomplish the gastrointestinal detection to the patient, after the completion of the same inspection, take out from the mouth gag through the gastroscopy pipe, then start motor 8, adjust mouth gag mechanism component 11, spacing mechanism component 13 and tongue pressing mechanism component 14 in proper order, the contact is to patient's oral cavity, tooth and tongue spacing.
