Description

Technical Field

[0001] The present invention belongs to the technical field of gastroscope auxiliary equipment, and in particular relates to a gastroscope oral expander. Background Art

[0002] A gastroscope is a sophisticated and expensive optical instrument (usually with an outer diameter of about 9 to 11 mm). When the scope passes through the mouth into the esophagus, if the patient unconsciously bites due to tension, discomfort or pharyngeal reflex, the hard teeth will bite directly on the scope, causing serious damage to the endoscope and even causing the optical fiber inside the scope to break, affecting image transmission. Therefore, an oral expander is needed to support the teeth when performing a gastroscopy on the patient.

[0003] When it is necessary to use an oral expander to expand the teeth, the existing technology usually uses an oral expander with a hole in the middle for the movement of the gastroscope tube to support the teeth. However, since the arrangement of teeth in the mouths of different patients may be uneven, different teeth may be tilted. When using the oral expander with a hole in the middle for the movement of the gastroscope tube to support the teeth, when the teeth in the patient's mouth are tilted, the teeth in the patient's mouth cannot be completely engaged in the grooves inside the oral expander, resulting in uneven force on the teeth in the patient's mouth. When the patient undergoes gastroscopy, unconscious biting movements can easily cause damage to the teeth, reducing the reliability of the tooth expansion. In addition, the oral expander with a hole in the middle for the movement of the gastroscope tube is large in size, and it is difficult to put the oral expander into the patient's mouth, which greatly reduces the expansion efficiency of the patient's mouth.

[0004] Therefore, we propose a gastroscopic oral expander to solve the above problems. Summary of the Invention

The inclination angle of the corresponding splint is adjusted according to the inclination angle of the patient's tooth side wall, which facilitates the use of the splint to fix the inner wall of the teeth, ensuring that the teeth in the patient's oral cavity can be closely connected to the mounting plate, facilitating gastroscopy for the patient. At the same time, after the mounting plate enters the patient's oral cavity, the distance between the two mounting plates is continuously increased to expand the oral cavity, avoiding the oral cavity expander with a hole in the middle for the movement of the gastroscope tube being large and difficult to place in the patient's oral cavity. In the process of expanding the oral cavity by the mounting plate, the angle of the mounting plate is continuously adjusted by the connecting plate so that the occlusal groove in the fixing plate can always correspond to the corresponding teeth, preventing the teeth from moving out of the fixing plate during the expansion process, thereby greatly improving the efficiency and reliability of oral cavity expansion.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The following electrical components are all electrically connected to the peripheral PLC controller.

[0026] Reference Figure 1 - Figure 7 A gastroscopic oral expander comprises a base plate 1, the top side wall of the base plate 1 is fixedly connected to a support rod 2, one end of the support rod 2 is fixedly connected to a first bidirectional electric telescopic rod 3, the telescopic ends of the first bidirectional electric telescopic rod 3 are fixedly connected to a support plate 4, the side walls of the support plate 4 are in contact with the side plate 5, the side walls of the two side plates 5 are fixedly connected to a mounting plate 6, the side walls of the two mounting plates 6 at opposite ends are fixedly connected with an adjustment component 7 for adjusting the inclination angle of the mounting plate 6 according to the size of the opening and closing of the oral cavity, the inner wall of the mounting plate 6 is fixedly connected to a tooth supporting component 8 for making it easier for the teeth to bite, and a tooth fixing component 9 for fixing the inner and outer walls of the teeth is provided on one side of the tooth supporting component 8.

[0027] In the embodiment, the adjustment assembly 7 includes two groups of connecting plates 71 symmetrically fixedly connected to the side walls of two mounting plates 6 at opposite ends, and each group of connecting plates 71 has two. The side walls of the connecting plates 71 are fixedly connected to round rods 72, and the two ends of the round rods 72 are rotatably connected to the same clamping plate 73. The side walls of the clamping plate 73 are fixedly connected to the first motor 74, and the output end of the first motor 74 passes through the side wall of the corresponding clamping plate 73 and is fixedly connected to one end of the round rod 72. The side wall of the opposite end of each group of clamping plates 73 is provided with the same second bidirectional electric telescopic rod 75, and the telescopic ends of the second bidirectional electric telescopic rod 75 are fixedly connected to the side walls of the corresponding clamping plate 73.

[0028] Specifically, after the mounting plate 6 enters the patient's oral cavity, the distance between the two mounting plates 6 continues to increase to expand the oral cavity, thereby preventing the oral cavity expander with a hole in the middle for the movement of the gastroscope tube from being too large and difficult to put into the patient's oral cavity. In the process of the mounting plate 6 expanding the oral cavity, the connecting plate 71 is used to continuously adjust the angle of the mounting plate 6 so that the occlusal groove 812 in the fixing plate 811 can always correspond to the corresponding teeth, thereby preventing the teeth from moving out of the fixing plate 811 during the expansion process, thereby greatly improving the efficiency and reliability of expanding the oral cavity.

[0029] In the embodiment, the tooth support assembly 8 includes a slide rail 81 fixedly connected to the inner wall of the mounting plate 6, and a slide plate 82 is slidably connected to the top side wall of the slide rail 81. A stopper 83 is fixedly connected to the inner wall of the mounting plate 6. The top side wall of the stopper 83 is provided with an annular opening 84 for the slide plate 82 to move.

[0031] The rod wall of the rotating rod 88 is fixedly connected to a connecting block 810, and the top side walls of the connecting block 810 are fixedly connected to a fixing plate 811.

The inner wall of each second groove 92 is fixedly connected to a fourth motor 93. The output end of each fourth motor 93 is fixedly connected to a side rod 94.

[0033] One end of the side rod 94 is rotatably connected to the inner wall of the first groove 91. The rod wall of the side rod 94 is fixedly connected to the second electric telescopic rod 95. The telescopic end of the second electric telescopic rod 95 is fixedly connected to the mounting block 96. The side wall of the mounting block 96 is provided with a T-shaped groove 97. A clamping plate 98 is movably connected inside the T-shaped groove 97.

[0034] Two screw holes are symmetrically provided on the side wall of the mounting block 96, and bolts 99 are rotatably connected to the internal threads of the corresponding screw holes.

The side walls of the two mounting seats 910 at opposite ends are fixedly connected to the same baffle 911, and the side walls of the baffle 911 are in conflict with the side walls of the splint 98.

[0035] Specifically, when the oral cavity needs to be expanded, the inclination angle of the occlusal groove 812 in the fixing plate 811 can be adjusted according to the inclination angle of the teeth in the patient's oral cavity, so that when the patient's teeth bite in the occlusal groove 812, the patient's teeth are completely engaged in the occlusal groove 812, so that the patient's teeth are evenly stressed, and the inclination angle of the corresponding splint 98 can be adjusted according to the inclination angle of the side wall of the patient's teeth, so that the inner wall of the tooth can be fixed with the splint 98, ensuring that the teeth in the patient's oral cavity can be tightly connected to the mounting plate 6, so as to facilitate gastroscopy for the patient.

[0036] The operating principle of the present invention is now described as follows:

[0037] In the present invention, when the patient's cavity needs to be expanded to facilitate the doctor to perform gastroscopy on the patient, the first bidirectional electric telescopic rod 3 is controlled to contract, driving the support plate 4 to move so that the support plate 4 does not fix the side plate 5. Then the doctor removes the mounting plate 6 and controls the slide rail 81 to start, driving the multiple slide plates 82 to move, so that the multiple fixing plates 811 move. After the multiple fixing plates 811 move to positions corresponding to the teeth in the patient's mouth, the slide rail 81 is controlled to close, and then the corresponding third motor 89 is controlled to start, driving the rotating rod 88 to rotate. During the rotation of the rotating rod 88, the connecting block 810 is controlled to drive the fixing plate 811 to rotate. After the inclination angle of the side wall of the fixing plate 811 is the same as the inclination angle of the corresponding tooth, the third motor 89 is controlled to close, and then the control The second motor 85 is started to drive the fixing plate 811 to rotate. After the occlusal groove 812 rotates to a position matching the corresponding tooth, the second motor 85 is controlled to be turned off. Then the doctor puts the mounting plate 6 into the patient's mouth. Then the patient's teeth bite into the corresponding occlusal groove 812 so that the patient's teeth are in contact with the corresponding occlusal rubber 813. Then the fourth motor 93 is controlled to start to drive the corresponding side rod 94 to rotate. During the rotation of the side rod 94, the mounting block 96 and the splint 98 are driven to rotate. After the inclination angle of the splint 98 is the same as the inclination angle of the inner wall of the corresponding tooth, the fourth motor 93 is controlled to be turned off. Then the second electric telescopic rod 95 is controlled to start to drive the splint 98 to move, and the splint 98 is used to fix the inner wall of the tooth to ensure that the patient's mouth is in the correct position. The teeth in the cavity can be tightly connected to the mounting plate 6, which is convenient for performing gastroscopy on the patient. Then, the second bidirectional electric telescopic rod 75 is controlled to start, driving the clamping plate 73 to move, so that the clamping plate 73 drives the corresponding mounting plate 6 to move, and the two mounting plates 6 are stretched apart, so that the patient's mouth is opened. In the process of increasing the distance between the two mounting plates 6, the first motor 74 is controlled to drive the round rod 72 to rotate continuously, so as to use the connecting plate 71 to drive the corresponding mounting plate 6 to rotate. When the distance between the two mounting plates 6 increases, the inclination angle of the fixing plate 811 in the mounting plate 6 is always the same as the inclination angle of the corresponding tooth, which is convenient for fixing the teeth, thereby completing the expansion of the oral cavity. After the gastroscopy is completed, the doctor removes the bolt 99 from the mounting seat 91 by tightening the bolt 99. 0, thereby removing the baffle 911. At this time, the baffle 911 does not block the splint 98. The doctor can directly pull out the splint 98 from the T-shaped slide 97 opened on the side wall of the mounting block 96, which is convenient for quickly disassembling and cleaning the splint 98 after use. When the oral cavity needs to be expanded, the inclination angle of the occlusal groove 812 in the fixing plate 811 can be adjusted according to the inclination angle of the patient's teeth in the occlusal groove 812, so that when the patient's teeth bite in the occlusal groove 812, the patient's teeth are completely occluded in the occlusal groove 812, so that the patient's teeth are evenly stressed, and the inclination angle of the corresponding splint 98 is adjusted according to the inclination angle of the patient's tooth side wall, so that the splint 98 can be used to fix the inner wall of the teeth, ensuring that the teeth in the patient's oral cavity can be closely connected to the mounting plate 6.This makes it easier to perform gastroscopy on patients. After the mounting plate 6 enters the patient's oral cavity, the distance between the two mounting plates 6 increases continuously to expand the oral cavity, thereby avoiding the difficulty of inserting the oral cavity expander with a hole in the middle for the gastroscope tube to move into the patient's oral cavity due to its large size. Furthermore, during the process of expanding the oral cavity with the mounting plate 6, the angle of the mounting plate 6 is continuously adjusted using the connecting plate 71, so that the occlusal groove 812 in the fixing plate 811 can always correspond to the corresponding teeth, thereby preventing the teeth from moving out of the fixing plate 811 during the expansion process. This greatly improves the efficiency and reliability of oral cavity expansion.
