For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] The inventor found that the existing expander cannot be adjusted according to the size of the patient's oral cavity during gastroscopy, so that it is more matched with the patient's oral cavity, increases the comfort of the patient during the examination, and limits and fixes the patient's teeth and gastroscope tube, which brings inconvenience to the doctor and the patient during gastroscopy.

[0031] Based on the above findings, the present application provides a protective support for gastroscopy, which comprises a supporting ring 1, a tooth groove 11 is formed on the upper and lower outer surfaces of the supporting ring 1, and an expansion sleeve 3 is connected to the two sides of the supporting ring 1 through a telescopic rod 2, a bite-proof assembly 4 is fixedly connected in the supporting ring 1, and a clamping assembly 5 for clamping and fixing the gastroscope tube is movably connected in the bite-proof assembly 4. Embodiment

[0032] Reference Figures 1-5 As shown in the present application, a protective support for gastroscopy is provided, which comprises a supporting ring 1, a tooth groove 11 is formed on the upper and lower outer surfaces of the supporting ring 1, and an expansion sleeve 3 is connected to the two sides of the supporting ring 1 through a telescopic rod 2, a bite-proof assembly 4 is fixedly connected in the supporting ring 1, and a clamping assembly 5 for clamping and fixing the gastroscope tube is movably connected in the bite-proof assembly 4.

[0033] Specifically, the expansion sleeve 3 is a "C" shaped structure, and an arc-shaped groove is formed through the side surface of the expansion sleeve 1, and the two sides of the oral cavity are expanded and opened by the expansion sleeve 3.

[0034] As an example, the supporting ring 1 is an elliptical structure ring, and the tooth groove 11 formed on the upper and lower outer surfaces of the supporting ring 1 can limit the patient's upper and lower teeth, so that the patient's upper and lower teeth remain in a separated state, and the patient's oral cavity is in an expanded state, which is convenient for inserting the gastroscope tube into the oral cavity to reach the stomach for screening of gastric cancer.

[0035] It should be noted that the telescopic rod is a prior art, and the inventor has not made any improvement.

[0036] Further, the inner surface of the supporting ring 1 is fixedly connected with a vertical rod 43, and the end of the vertical rod 43 is fixedly connected with the bite-proof sleeve 41.

[0037] It should be noted that the sliding groove 42 is transversely formed on the upper and lower inner surfaces of the bite-proof sleeve 41.

[0038] Further, the anti-bite sleeve 41 is provided with a vertical rod 43, the end of the vertical rod 43 is fixedly connected with the inner surface of the support ring 1. Through the space between the support ring 1 below the anti-bite sleeve 41, the tongue of the patient can be in a natural state without being restricted, thereby reducing the discomfort of the patient during the oral cavity expansion process.

[0039] In the above technical solution, the clamping assembly 5 includes a set of clamping half-rings 51, the upper and lower ends of each clamping half-ring 51 are provided with sliding blocks 52, the sliding blocks 52 are in sliding fit with the sliding grooves 42, the outer side of the clamping half-ring 51 is rotationally connected with a screw rod 53, and the screw rod 53 is in threaded connection with the left and right side walls of the anti-bite sleeve 41.

[0040] Especially, through the sliding fit between the sliding blocks 52 and the sliding grooves 42, on the one hand, the rotation of the clamping half-ring 51 during the rotation of the screw rod 53 can be avoided, thereby realizing the limitation of the clamping half-ring 51; on the other hand, the clamping half-ring 51 can be realized to be close to each other in a straight line direction under the limitation of the sliding grooves 42, thereby realizing the clamping and fixing of the gastroscope tube.

[0041] Preferably, the tooth groove 11 is provided with a rubber pad, which can avoid the problem that the patient's teeth are injured by contacting the hard material.

[0042] Now, the application of the protective support device for gastroscope in the early gastric cancer screening process will be described in detail in combination with the embodiments.

[0043] The early screening methods of gastric cancer usually include blood test, gastroscopy and endoscopic ultrasonography. Although the blood test is more convenient, the gastroscopy is usually selected in the clinic to screen early gastric cancer. The gastroscopy can carefully check the gastric mucosa, which can not only present an intuitive and clear image, but also timely take out suspicious lesion tissues for pathological examination.

[0044] During the examination operation, the patient takes a left lateral position, the legs are bent, the collar is loosened, the head is padded with a thin pillow, the head is slightly tilted backward, and the pharynx and esophagus become a straight line.

[0045] The doctor adjusts the length of the telescopic rod 2 according to the size of the patient's oral cavity, thereby adjusting the distance between the expansion sleeves 3, and places the expansion sleeves 3 on the buccal part of the patient's oral cavity, so that the patient's oral cavity is in an open state, at this time, the upper and lower teeth of the patient are respectively occluded in the tooth grooves 11 provided on the support ring 1, and the rubber pad in the tooth groove 11 plays a buffering role on the patient's teeth.

[0046] Further, the doctor holds the gastroscope operation part, inserts the gastroscope into the pharynx under direct vision, and needs to carefully observe the oropharynx and hypopharynx for lesions from the oropharynx. Then, the gastroscope is slowly inserted into the esophagus from the left piriform fossa, the gastroscope tip is slowly inserted into the cardia after passing the dentate line, and then the stomach cavity is checked from the stomach bottom to the left and up, and then through the prepyloric region, duodenal bulb, descending part and nipple part, the duodenum, gastric antrum, gastric angle, gastric body, gastric fundus and esophagus can be checked one by one.

[0047] During the examination process, when it is needed to stop the tube insertion for observation, the clamping half rings 51 are driven to move close to each other along the sliding grooves 42 by rotating the screw rods 53 on both sides of the anti-bite sleeve 41, so as to clamp and fix the gastroscope tube by the clamping half rings 51, without the need for the doctor to manually fix the gastroscope tube, thereby reducing the working intensity of the doctor.

[0048] After the examination is completed, the doctor needs to withdraw the gastroscope, and air needs to be extracted as much as possible during the withdrawal of the gastroscope, so as to prevent abdominal distension. After the patient wakes up, the patient sits up and spits out saliva, and the patient and family members are informed of the examination situation and matters needing attention after the examination. The patient is observed for 30 minutes, and can leave if there is no abnormality.

[0049] In summary, although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
