Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular, to an auxiliary device suitable for gastroscopy examination and treatment. Background Art

[0002] An electronic gastroscope is a medical electronic optical instrument that can be inserted into the human gastric cavity for direct observation, diagnosis, and treatment of gastrointestinal diseases. It consists of an objective lens system, an image plane photoelectric sensor, an A / D conversion integrated module, etc. The electronic gastroscope images the objects in the gastric cavity onto the image plane photoelectric sensor through a tiny objective lens system, then transmits the received image signal to the image processing system, and finally outputs the processed image on a monitor. The electronic gastroscope can obtain high-definition images, and various image processing can be performed through a computer, such as three-dimensional imaging, measuring mucosal blood flow, mucosal local hemoglobin content, and local temperature. Gastroscopy examination is recognized as the most reliable method for diagnosing esophageal, gastric, and duodenal diseases.

[0003] During gastroscopy examination, the insertion part of the endoscope needs to be inserted from the patient's mouth into the patient's stomach. The patient needs to keep their mouth open throughout the process and cannot close it, let alone bite the endoscope. Due to the different degrees of patient cooperation and the uncertainty of anesthetized patients, in order to protect the safety of the patient and the expensive endoscope, it is necessary to ensure that the patient's mouth is kept open and cannot bite during the entire examination process. Therefore, a corresponding auxiliary device is required to cooperate with gastroscopy examination and treatment.

[0004] The existing endoscopic examination auxiliary devices have the following problems and deficiencies: The tooth fixation part cannot be adjusted according to the conditions of different patients: Some patients with oral diseases have limited mouth opening and closing degrees, the device may accidentally fall off during the anesthesia process of anesthetized patients, and it needs to be urgently removed (or re-worn) in case of special situations during the examination and treatment of anesthetized patients.

[0005] For example, a digestive endoscope mouthpad disclosed in a Chinese patent with the publication number CN213248957U has a circular tubular structure in the part that enters the mouth, and the protrusion for fixing teeth cannot move. It is difficult for some special patients and anesthetized patients to remove or re-wear it in a timely manner, and it does not conform to the physiological structure of the oral teeth, so the patient feels uncomfortable when wearing it for a long time. Utility Model Content

[0006] In order to improve the problem that it is difficult for the existing endoscopic examination auxiliary device to be conveniently re-worn for special patients, the present application provides an auxiliary device suitable for gastroscopy examination and treatment.

[0007] The auxiliary device suitable for gastroscopy examination and treatment provided by the present application adopts the following technical solutions:

[0008] An auxiliary device suitable for gastroscopy examination and treatment includes:

[0009] A cylinder body, which has openings at both ends and has flat surfaces provided on two opposite side walls thereof, and the cylinder body is provided with a notch at the flat surface;

[0010] A spring strip, integrally connected to the edge of the notch on the cylinder body, and both ends thereof are arranged with gaps with two opposite sides of the notch, and the spring strip has at least one bent portion;

[0011] An occlusal plate, integrally formed on the spring strip;

[0012] A baffle plate, fixedly connected to the occlusal plate and arranged at an angle with the occlusal plate, and the distance between the baffle plate and the protruding portion of the spring strip is greater than the width of the human tooth occlusal area;

[0013] A fixing structure, arranged on the cylinder body and used for fixing the cylinder body on the patient's face.

[0014] Furthermore, a tongue depressor is fixedly connected to one end of the cylinder body away from the baffle plate.

[0015] Furthermore, an arc transition edge is provided between the side of the tongue depressor and the cylinder body.

[0016] Furthermore, one end of the tongue depressor away from the cylinder body is bent in a direction away from the axis of the cylinder body.

[0017] Furthermore, two convex plates extending radially along the outer peripheral wall of the cylinder body are fixedly connected to the outer peripheral wall of the cylinder body, the convex plates are located between the two baffle plates, and the fixing structure includes an elastic band with two ends respectively connected to the two convex plates.

[0018] Furthermore, a magic tape is arranged at the end of the elastic band, and a through groove for the end of the elastic band and the magic tape to pass through is arranged on the convex plate.

[0019] Furthermore, a through hole is penetrated and opened on the convex plate.

[0020] Furthermore, the cylinder body, the spring strip, the occlusal plate and the baffle plate are integrally injection molded from medical plastic.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. By means of the arrangement of the spring strip, the occlusal plate and the baffle plate, it is beneficial to both the stability of the auxiliary device of the present application and not easy to fall off, and it is also beneficial to the removal and re-wearing of the auxiliary device. Especially for some special situations of anesthetized patients where emergency removal or reinstallation is required, it can protect the oral mucosa, teeth and mandible of the patient to the greatest extent, and even win time for the rescue of some patients;

[0023] 2. By setting the tongue depressor and the arc transition edge, for some patients with oral diseases, the arc transition edge design of the auxiliary device of the present application helps the convenient insertion and wearing of the auxiliary device, and can effectively protect the patient's teeth and mandible; and after the patient wears the auxiliary device, the patient's tongue can be pressed below, which helps to protect the patient's tongue mucosa and fix the movement of the patient's tongue, effectively preventing the visual field blockage of the tongue during the endoscope insertion process, and also effectively preventing the patient from having a posterior displacement of the tongue;

[0024] 3. In view of the fact that during previous surgeries, when the patient needed to be suctioned, the doctor had to stop the operation and even pull out the endoscope. However, for the auxiliary device of the present application, neither does the doctor need to stop the operation nor does the doctor need to pull out the endoscope. The suction tube can be inserted into the patient's oral cavity through the perforations provided on the convex plate to aspirate sputum, saliva, and blood, greatly reducing the time for the patient's examination and treatment.

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1 and Figure 2 The present application discloses an auxiliary device suitable for gastroscopy and treatment, which includes:

[0038] The cylinder 1 is open at both ends and has two opposite side walls provided with flat surfaces 11. The cylinder 1 is provided with a notch 12 extending from one end thereof toward the axial direction thereof at the flat surface 11.

[0039] There are two spring strips 21, which correspond to the two notches 12 one by one. The spring strips 21 are integrally connected to the edges of the notches 12 on the cylinder 1. The length direction of the spring strips 21 is orthogonal to the axial direction of the cylinder 1, and the spring strips 21 and the two opposite sides of the notches 12 are both provided with gaps. The spring strips 21 have at least one bending portion, which can be "V"-shaped or "U"-shaped. The convex portion of the bending portion needs to be located on the side of the flat surface 11 away from the axis of the cylinder 1, and also needs to be protruded from the flat surface 11 to provide a certain limiting effect.

[0040] The bite plate 22 is integrally formed on the spring strip 21 and extends to the opening end of the notch 12 .

[0041] The baffle 23 is fixedly connected to the bite plate 22 and is set at an angle with the bite plate 22. The distance between the baffle 23 and the raised portion of the spring strip 21 is greater than the width of the bite area of ​​human teeth. The baffle 23 is located on the side of the bite plate 22 away from the axis of the cylinder 1.

[0042] The fixing structure is arranged on the cylinder body 1 and is used for fixing the cylinder body 1 on the patient's face.

[0043] The barrel 1, the spring strip 21, the bite plate 22 and the baffle 23 are integrally injection-molded from medical plastics, so that the auxiliary device of the present application can be disposable, thus reducing the cost of use.

[0044] In this way, when using the auxiliary device of the present application, the end of the cylinder 1 without the baffle 23 can be inserted into the patient's oral cavity, and then the two baffles 23 are pressed at the same time, so that the two baffles 23 drive the two bite plates 22 to flip in the direction of approaching each other. The setting of the spring strip 21 can provide the deformation amount and the ability to reset after deformation for the flipping of the bite plate 22 on the cylinder 1; therefore, when the cylinder 1 is inserted into the patient's oral cavity until the patient's teeth pass over the raised portion of the spring strip 21, the pressure on the baffle 23 is stopped, and the two bite plates 22 are flipped and reset in the opposite directions under the reset action of the spring strip 21, so that the patient's teeth can be bitten on the two bite plates 22. The raised portions of the baffle 23 and the spring strip 21 are arranged on the inner and outer sides of the patient's teeth, which can fix the cylinder 1 to a certain extent. Finally, the cylinder 1 is firmly fixed to the patient's face through the fixing structure. At this time, the inner cavity of the cylinder 1 forms a channel for inserting an endoscope, which is conducive to gastroscopy. Therefore, by means of the arrangement of the spring strip 21, the bite plate 22 and the baffle 23, the wearing and removing efficiency of the auxiliary device of the present application can be greatly improved, the operation time can be saved, and it is especially convenient to remove and re-wear the auxiliary device in an emergency.

[0045] In addition, refer to Figure 1 and Figure 3 A tongue depressor 3 is fixedly connected to the end of the barrel 1 away from the baffle 23, and an arc-shaped transition edge 31 is provided between the side of the tongue depressor 3 and the barrel 1. The end of the tongue depressor 3 away from the barrel 1 is bent in the direction away from the axis of the barrel 1. The setting of the tongue depressor 3 can prevent the patient's tongue from moving, ensure a clear endoscopic field of view, and effectively prevent the patient's tongue from falling back; the setting of the arc-shaped transition edge 31 is used for wearing and removing special patients such as patients with limited oral opening and closing, anesthetized patients, etc., and there is no need to pry the patient's teeth or mandible when wearing or removing it, which can protect the patient's oral mucosa, teeth and mandible to the greatest extent, and even buy time for the rescue of some patients.

[0046] In order to facilitate the application to adapt to patients of different body types, refer to Figure 2 and Figure 4 Two convex plates 4 extending in the radial direction are fixedly connected to the outer peripheral wall of the cylinder 1, and the convex plate 4 is located between the two baffles 23. The fixing structure includes an elastic band 51 whose two ends are respectively connected to the two convex plates 4, and a Velcro 52 is provided at the end of the elastic band 51. The convex plate 4 is provided with a through groove 41 for the end of the elastic band 51 and the Velcro 52 to pass through; the Velcro 52 is provided with a fur surface and a hook surface on the same surface at both ends thereof, so that after the Velcro 52 passes through the through groove 41, the fur surface and the hook surface can adjust the bonding position as needed to adjust the actual length of the Velcro 52, thereby ensuring the wearing stability of the auxiliary device and increasing the comfort of the patient.

[0047] And, refer to Figure 2 and Figure 4, a through hole 42 is formed through the convex plate 4, and the suction tube can pass through the through hole 42. The through hole 42 can be formed on one side of the convex plate 4 or on both sides of the convex plate 4. In this way, in view of the fact that during previous operations, when the patient needed to be suctioned, the doctor had to stop the operation and even pull out the endoscope. However, for the auxiliary device of the present application, the doctor neither needs to stop the operation nor pull out the endoscope. The suction tube can be inserted into the patient's mouth through the through hole 42 to aspirate sputum, saliva, and blood, greatly reducing the time for patient examination and treatment.

[0048] The implementation principle of an auxiliary device applicable to gastroscopy examination and treatment in an embodiment of the present application is as follows:

[0049] When using the auxiliary device of the present application, the end of the cylinder 1 without the baffle 23 can be inserted into the patient's mouth, and then the two baffles 23 are pressed simultaneously, so that the two baffles 23 drive the two occluding plates 22 to flip in the direction of approaching each other. The setting of the spring strip 21 can provide the deformation amount and the ability to reset after deformation for the flipping of the occluding plate 22 on the cylinder 1. Therefore, when the cylinder 1 is inserted into the patient's mouth until the patient's teeth cross the protruding part of the spring strip 21, the pressure on the baffle 23 is stopped. The two occluding plates 22 flip and reset in the direction of departing from each other under the reset action of the spring strip 21, so that the patient's teeth can bite on the two occluding plates 22. The baffle 23 and the protruding part of the spring strip 21 are arranged on the inner and outer sides of the patient's teeth respectively, which can fix the cylinder 1 to a certain extent. Finally, the cylinder 1 is firmly fixed to the patient's face through the elastic band 51. At this time, a channel for inserting the endoscope is formed in the inner cavity of the cylinder 1, which is beneficial for gastroscopy examination. Therefore, by means of the settings of the spring strip 21, the occluding plate 22, and the baffle 23, the wearing and removing efficiency of the auxiliary device of the present application can be greatly improved, the operation time can be saved, and it is especially convenient to remove and re-wear the auxiliary device in case of emergency.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
