Description

Technical Field

[0001] The present invention relates to the technical field of endoscopic inspection consumables, and in particular to an endoscopic inspection oral cavity supporting device. Background Art

[0002] An endoscope is an optical instrument that is inserted from the outside of the body through the natural cavity of the human body to examine diseases in the body. It can directly observe the lesions in the internal cavity of the organs, determine their location and range, and can be used for photography, biopsy or film brushing, which greatly improves the accuracy of cancer diagnosis. An endoscope bite is an auxiliary tool used for endoscopic examination and surgery, also known as an endoscope fixer, endoscope bracket or endoscope fixing clip. This product is mainly used to fix the endoscope in a specific position to facilitate doctors to perform visual inspection, operation and treatment.

[0003] Endoscope bites can be divided into straight bites, oblique bites and U-shaped bites according to their shapes. The length of the straight bite is equal to the diameter of the endoscope tube, and it is often used in narrow areas; the length of the oblique bite is longer than the diameter of the endoscope tube, and it is often used in some difficult-to-reach locations; the ends of the U-shaped bite are bent upward, and it is often used to photograph and remove bile duct stones. Regardless of the shape of the endoscope bite, it consists of a tubular bite part and straps tied at both ends of the bite part. This type of endoscope has a simple structure and is easy to be standardized and mass-produced. However, it cannot fit closely to different mouth shapes, the bite comfort is poor, and the scope of application is small. Summary of the invention

[0004] In view of this, the present invention aims to provide an oral support device for endoscopic inspection, which can adapt to mouth shapes of different sizes and has the advantages of a wide range of applications and high occlusal comfort.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] An oral support device for endoscope inspection includes a support assembly;

[0007] An upper jaw assembly is slidably arranged on the top of the support assembly in a horizontal direction;

[0008] A lower jaw assembly is slidably arranged at the bottom of the support assembly in a horizontal direction;

[0009] A guide tube, passing through the middle of the support assembly;

[0010] A deflector is detachably disposed at the rear of the support assembly:

[0011] Further, the support assembly includes a top plate connected to the upper jaw assembly;

[0012] a bottom plate connected to the lower jaw assembly;

[0013] an elastic member, vertically connected between the top plate and the bottom plate;

[0014] The top surface of the top plate and the bottom surface of the bottom plate are respectively provided with protrusions for restricting the sliding of the upper jaw assembly and the lower jaw assembly;

[0015] The opposite surfaces of the top plate and the bottom plate are provided with mounting grooves which are consistent with the shape of the guide tube.

[0016] Further, the elastic member includes a pin, which is vertically connected to the bottom surface of the top plate;

[0017] A cylinder body is vertically connected to the top surface of the bottom plate and sleeved on the pin shaft;

[0018] A cushion block is arranged at the bottom of the cylinder and abuts against the pin shaft.

[0019] Further, the guide tube includes a tube body, which is constructed into two parts that fit with the upper and lower inner walls of the installation groove;

[0020] The flexible part is connected to the two parts of the tube body to form a continuous tube shape and is foldably arranged between the top plate and the bottom plate.

[0021] Further, the upper jaw assembly includes two upper bite plates, which are constructed to be symmetrical to each other and slidably disposed on the top of the support assembly;

[0022] The upper connecting rod is slidably arranged between the two upper bite plates.

[0023] Further, the lower jaw assembly includes two lower bite plates, which are constructed to be symmetrical to each other and slidably disposed at the bottom of the support assembly;

[0024] The lower connecting rod is slidably arranged between the two lower bite plates.

[0025] Furthermore, both the upper bite plate and the lower bite plate are provided with bite grooves.

[0026] Furthermore, a gasket is arranged in the engagement groove.

[0027] Furthermore, an arc portion is provided at one end of the guide plate away from the support assembly, and the arc portion is made of a flexible material. Compared with the prior art, the present invention has the following advantages:

[0028] An oral support device for endoscopic examination in the present invention can play a role in fixing and limiting the installation of the upper jaw component and the lower jaw component. The upper jaw component and the lower jaw component can respectively effectively support the upper and lower jaws of patients who need to undergo endoscopic examination. The sliding installation method of the upper jaw component and the lower jaw component can be used to change the relative position and adjust the shape and size according to the patient's mouth shape, further improve the fit with the patient's mouth, reduce the patient's discomfort during biting, and can adapt to different mouth shapes. The guide tube cooperates with the guide plate to guide and limit the movement of the endoscope, so that the endoscope can follow the inner wall of the guide tube into the patient's body. The guide plate can form a barrier between the endoscope and the patient's throat, which can not only reduce the patient's discomfort, but also have a barrier effect on the saliva secreted by the patient's mouth, which is conducive to preventing its backflow from choking or contaminating the lens.

[0029] Secondly, by setting the support component as a structure of a top plate, a bottom plate and an elastic member, the support component can form an elastic support for the upper jaw component and the lower jaw component, so that the distance between the upper jaw component and the lower jaw component can be slightly changed due to different bite forces, thereby improving the bite comfort and reducing the discomfort caused by the increase of bite force due to stimulation during the patient examination. By setting the protrusion along the sliding direction of the upper jaw component and the lower jaw component, it plays a limiting role in the relative sliding between the upper jaw component and the top plate and the relative sliding between the lower jaw component and the bottom plate, thereby improving the stability of the upper jaw component and the lower jaw component. By setting a mounting groove consistent with the shape of the guide tube between the top plate and the bottom plate, the contact area between the top plate and the bottom plate and the guide tube is increased, so that the support of the top plate and the bottom plate to the guide tube is more stable, avoiding the possibility of misalignment of the guide tube and the support component during endoscopic examination.

[0030] By configuring the elastic member as a combination of a pin, a cylinder and a pad, the pad made of a flexible material can provide elastic support between the top plate and the bottom plate. The pin connected to the top plate is inserted into the cylinder connected to the bottom plate, so that the bottom plate can limit the top plate from overcoming the elastic force and moving, so that the top plate and the bottom plate can move in a vertical direction.

[0031] Thirdly, by setting the guide tube as a structure formed by combining a rigid tube body and a soft flexible part, the guide tube as a whole has elasticity, and can change its shape as the relative positions of the top plate and the bottom plate change, so as to keep in close contact with the installation groove, thereby ensuring the stability of the support effect. By foldably arranging the flexible part between the top plate and the bottom plate, the flexible part can cooperate with the elastic member to form an elastic support for the top plate and the bottom plate, increase the elastic force before the top plate and the bottom plate approach each other to the limit position, and improve the support for the top plate and the bottom plate.

[0032] In addition, by providing an arc portion at one end of the guide plate away from the support assembly, and by providing the arc portion in a semi-arc shape that fits the tongue root, the tongue root of the patient can be pressed, which is beneficial to improving the sealing of the guide plate to saliva and improving the effect of the guide plate in preventing saliva from flowing back and causing choking. By providing the arc portion to be made of a flexible material, the stimulation to the tongue root of the patient can be reduced, and the comfort level can be improved.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] The following will refer to the attached Figure 1 To Attachment Figure 5 The present invention is described in detail with reference to embodiments.

[0046] The present embodiment relates to an oral support device for endoscopic inspection, which can adapt to mouth shapes of different sizes and has the advantages of a wide range of applications and high occlusal comfort.

[0047] In terms of overall structure, refer to Figure 1The oral support device for endoscope inspection of the present embodiment comprises a support assembly 1, an upper jaw assembly 2, a lower jaw assembly 3, a guide tube 4 and a guide plate 5. The upper jaw assembly 2 and the lower jaw assembly 3 are respectively slidably arranged at the top and bottom of the support assembly 1 along the horizontal direction. The guide tube 4 is fixedly arranged in the middle of the support assembly 1 along the horizontal direction. The guide plate 5 is detachably installed at the rear of the support assembly 1.

[0048] By setting the support component 1, the upper jaw component 2 and the lower jaw component 3 can be fixed and limited in their installation. The upper jaw component 2 and the lower jaw component 3 can respectively effectively support the upper and lower jaws of patients who need to undergo endoscopic examination. The sliding installation method of the upper jaw component 2 and the lower jaw component 3 can be used to change the relative position and adjust the shape and size according to the patient's mouth shape, further improve the fit with the patient's mouth, reduce the patient's discomfort during the bite process, and can adapt to different mouth shapes. The guide tube 4 cooperates with the guide plate 5 to guide and limit the movement of the endoscope, so that the endoscope can follow the inner wall of the guide tube 4 to enter the patient's body. The guide plate 5 can form a barrier between the endoscope and the patient's throat, which can not only reduce the patient's discomfort, but also have a barrier effect on the saliva secreted by the patient's mouth, which is conducive to preventing its backflow from choking or contaminating the lens.

[0049] Reference Figure 1 and Figure 2 In order to achieve the purpose of fastening and supporting the upper jaw assembly 2 and the lower jaw assembly 3, in this embodiment, the support assembly 1 includes a top plate 101, a bottom plate 102 and an elastic member 103. The top plate 101 is connected to the upper jaw assembly 2, and the bottom plate 102 is connected to the lower jaw assembly 3. The elastic member 103 is vertically connected between the top plate 101 and the bottom plate 102. Both the top plate 101 and the bottom plate 102 are provided with a protrusion 104. The top plate 101 and the bottom plate 102 have mounting grooves 105 on their opposite surfaces, and the mounting grooves 105 can be circular grooves that are consistent with the shape of the guide tube 4.

[0050] By setting the support assembly 1 to a structure of a top plate 101, a bottom plate 102 and an elastic member 103, the support assembly 1 can form an elastic support for the upper jaw assembly 2 and the lower jaw assembly 3, so that the distance between the upper jaw assembly 2 and the lower jaw assembly 3 can be slightly changed due to different bite forces, thereby improving the bite comfort and reducing the discomfort caused by the increase of bite force during the patient's examination due to stimulation. By setting the protrusion 104 along the sliding direction of the upper jaw assembly 2 and the lower jaw assembly 3, it plays a limiting role in the relative sliding between the upper jaw assembly 2 and the top plate 101 and the relative sliding between the lower jaw assembly 3 and the bottom plate 102, thereby improving the stability of the upper jaw assembly 2 and the lower jaw assembly. By setting a mounting groove 105 that is consistent with the shape of the guide tube 4 between the top plate 101 and the bottom plate 102, the contact area between the top plate 101 and the bottom plate 102 and the guide tube 4 is increased, so that the support of the guide tube 4 by the top plate 101 and the bottom plate 102 is more stable, thereby avoiding the possibility of misalignment of the guide tube 4 and the support assembly 1 during endoscopic examination.

[0051] Reference Figure 2 The elastic member 103 includes a pin, a cylinder and a cushion block. The pin is vertically connected to the bottom surface of the top plate 101, and the cylinder is vertically connected to the top surface of the bottom plate 102. The pin is inserted into the cylinder. A cushion block is installed at the bottom of the cylinder, which is made of elastic material and abuts against the end surface of the pin.

[0052] By configuring the elastic member 103 as a combination of a pin, a cylinder and a cushion, the cushion made of a flexible material can provide elastic support between the top plate 101 and the bottom plate 102. The pin connected to the top plate 101 is inserted into the cylinder connected to the bottom plate 102, so that the bottom plate 102 can limit the top plate 101 in the process of overcoming the elastic force and moving, so that the top plate 101 and the bottom plate 102 move in the vertical direction.

[0053] Reference Figure 1 and Figure 5 In order to guide the endoscope lens and introduce it into the patient's body from the patient's mouth, the guide tube 4 includes a tube body 401 and a flexible portion 402. The tube body 401 is divided into two parts. The two parts of the tube body 401 are respectively arranged in contact with the inner walls of the mounting grooves 105 on the top plate 101 and the bottom plate 102. The tube body 401 is made of a rigid material. The flexible portion 402 is connected between the two parts of the tube body 401 and is foldably arranged between the top plate 101 and the bottom plate 102. The flexible portion 402 has a tendency to open when no external force is applied.

[0054] By setting the guide tube 4 as a structure formed by combining a rigid tube body 401 and a soft flexible part 402, the guide tube 4 as a whole has elasticity, and can change its shape as the relative position of the top plate 101 and the bottom plate 102 changes, so as to keep in contact with the installation groove 105, thereby ensuring the stability of the supporting effect. By foldably setting the flexible part 402 between the top plate 101 and the bottom plate 102, the flexible part 402 can cooperate with the elastic member 103 to form an elastic support for the top plate 101 and the bottom plate 102, increase the elastic force before the top plate 101 and the bottom plate 102 approach each other to the limit position, and improve the support for the top plate 101 and the bottom plate 102.

By providing an arcuate bite groove on the upper surface of the upper bite plate 201 and providing a gasket in the bite groove, the fit between the upper bite plate 201 and the patient's upper jaw can be improved, thereby improving comfort.

[0057] Reference Figure 1 and Figure 4 The lower jaw assembly 3 includes two lower bite plates 301 and a lower connecting rod 302 connected between the two lower bite plates 301. The lower connecting rod 302 is slidably connected between the two lower bite plates 301. An arc-shaped bite groove is formed on the lower surface of the lower bite plate 301. A gasket is arranged in the bite groove.

[0058] By configuring the lower jaw assembly 3 to be a structure in which two lower bite plates 301 are slidably connected via a lower connecting rod 302, the distance between the two lower bite plates 301 can be adjusted by pulling, thereby adapting to different mouth shapes. By providing an arcuate bite groove on the lower surface of the lower bite plate 301 and providing a gasket in the bite groove, the fit between the lower bite plate 301 and the patient's lower jaw can be improved, thereby improving comfort.
