Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary instruments for treatment and examination, and in particular to a dental pad for rigid endoscopes. Background Technology
[0002] During bronchial examinations, a rigid bronchoscope (rigid bronchoscope) is inserted into the large airways through the patient's mouth. Under direct visualization with the rigid bronchoscope, procedures such as silicone stent placement and removal, electrocautery, balloon dilation, cryotherapy, and laser treatment are performed. To prevent the teeth from obstructing the insertion of the rigid bronchoscope, a mouth pad is usually placed in the patient's mouth. This mouth pad includes a cylindrical occlusal region. During the examination, the rigid bronchoscope can be inserted through this occlusal region. However, due to the restriction imposed by the sidewalls of the mouth pad, adjustments to the bronchial angle and rotation are not easily possible. Utility Model Content
[0003] The purpose of this utility model is to provide a dental pad specifically for rigid endoscopes, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a rigid endoscope dental pad, comprising: an occlusal part; a pressure plate installed at one end of the occlusal part, with fixing straps installed on both sides of the pressure plate; and a rotating sleeve rotatably installed on the inner side of the occlusal part near the end of the pressure plate, wherein a plurality of circumferentially distributed ball bearings are accommodated between the rotating sleeve and the occlusal part.
[0005] This technical solution has at least the following beneficial effects: During the examination, after the patient puts on the bite block, the rigid endoscope is inserted into the occlusal region and also passes through the inner side of the rotating sleeve. Due to the presence of the ball bearing, the rotating sleeve can rotate smoothly relative to the occlusal region. When rotating the rigid endoscope, the rotation of the rotating sleeve relative to the occlusal region can be used to achieve convenient rotation operation, thereby reducing the difficulty in operating the rigid endoscope due to the large friction between the outer wall of the rigid endoscope and the inner wall of the occlusal region, which helps to ensure the smooth operation of the rigid endoscope.
[0006] As a further improvement to the above technical solution, a fixing ring is installed on the outer side of the rotating sleeve, and the fixing ring is detachably installed on the pressure plate. This facilitates the installation or removal of the rotating sleeve.
[0007] As a further improvement to the above technical solution, hooks are provided on both sides of the fixing ring, and the pressing plate has a slot for the hooks to engage.
[0008] As a further improvement to the above technical solution, an inner ring track is provided on the inner side of the fixed ring, and an outer ring track is provided on the outer side of the rotating sleeve, which is sleeved on the outer side of the inner ring track, and the ball is disposed between the inner ring track and the outer ring track.
[0009] As a further improvement to the above technical solution, one or both ends of the rotating sleeve are configured with a flared structure to facilitate the passage and operation of the rigid lens.
[0010] As a further improvement to the above technical solution, a plurality of interconnected balloons are arranged around the axis at the end of the biting part away from the pressure plate. When the rigid endoscope is inserted into the biting part, the balloons can abut against the rigid endoscope, thereby restricting the position of the rigid endoscope and preventing excessive shaking of the rigid endoscope during movement and rotation, which would affect the actual working position of the end of the rigid endoscope and improve the accuracy of rigid endoscope operation.
[0011] As a further improvement to the above technical solution, the balloon is connected to an air delivery tube, which passes through the pressure plate and is equipped with a switch interface. By opening the switch interface and connecting it to the output end of a manual ball valve or an air valve, the balloon can be inflated according to the actual needs of adjusting the tightness of the rigid endoscope.
[0012] As a further improvement to the above technical solution, a plurality of arc-shaped tubes are installed at the end of the bite portion away from the pressure plate, and the two ends of the arc-shaped tubes are respectively connected to two adjacent balloons. The arc-shaped tubes can restrict the position of the balloons, so that the insertion of the rigid endoscope is less likely to be affected when the balloons are deflated.
[0013] As a further improvement to the above technical solution, an arc-shaped loop is provided on the outer wall of the clenching part to restrict the air tube, thereby reducing the discomfort caused by the air tube to the oral cavity.
[0014] As a further improvement to the above technical solution, Velcro is connected between the two fixing straps located on both sides of the pressure plate. This facilitates wrapping the fixing straps around the patient's head and securing them with the Velcro. Attached Figure Description

[0024] Reference Figure 1-3 The rigid endoscope dental pad includes an occlusal section 100 and a pressure plate 200.
[0025] The clenching part 100 has a cylindrical structure. One end of the clenching part 100 is connected to the pressure plate 200, and the pressure plate 200 is flush with the end face of the clenching part 100. The two sides of the pressure plate 200 are curved to better fit the human face.
[0026] Both sides of the pressure plate 200 are provided with through holes, so that both sides of the pressure plate 200 are provided with mounting ears. Fixing straps 210 are inserted into the through holes. The fixing straps 210 are sewn to themselves after surrounding the mounting ears, so that the fixing straps 210 can be installed on the pressure plate 200.
[0027] A Velcro 211 is connected between the ends of the two fixing straps 210 away from the pressure plate 200. The Velcro 211 includes a hook side and a loop side, which are sewn onto the two fixing straps 210 respectively, so that the two fixing straps 210 can be connected by the Velcro 211 to restrict the pressure plate 200 to the position of the human face, that is, to restrict the occlusal part 100 in the human mouth. The patient's teeth abut against the outside of the occlusal part 100, so as not to affect the operation of the rigid endoscope inserted inside the occlusal part 100.
[0028] A retaining ring 320 is installed at one end of the bite portion 100 near the pressure plate 200, and the axis of the retaining ring 320 coincides with the axis of the bite portion 100. A rotating sleeve 300 is rotatably mounted on the inner side of the retaining ring 320. Specifically, the retaining ring 320 is integrally formed with an inner ring track 400, and an outer ring track 410 is provided on the outer side of the rotating sleeve 300. The inner side of the outer ring track 410 abuts against the outer side of the inner ring track 400, thereby forming a closed circular track between the inner ring track 400 and the outer ring track 410. The circular track is filled with a plurality of circumferentially distributed ball bearings 310, with the two sides of the ball bearings abutting against the bottom wall of the inner ring track 400 and the bottom wall of the outer ring track 410, respectively, thereby making the rotation of the rotating sleeve 300 relative to the retaining ring 320 smoother and more stable.
[0029] After the rigid endoscope passes through the jaw 100, it can rotate or swing smoothly by relying on the rotation of the rotating sleeve 300 relative to the jaw 100 during the rotation or swinging process of the rigid endoscope, thereby improving the convenience and smoothness of rigid endoscope operation and reducing the occurrence of jamming.
[0030] Furthermore, a plurality of balloons 500 are installed at the end of the biting part 100 away from the pressure plate 200. The plurality of balloons 500 are arranged in a ring around the axis of the biting part 100, and the circumferential radius of the center of the plurality of balloons 500 is slightly smaller than the inner radius of the biting part 100, so that the plurality of balloons 500 can more easily squeeze each other inward.
[0031] An arc-shaped tube 520 is installed between two adjacent balloons 500, and the diameter of the arc-shaped tube 520 is smaller than the radius of the balloon 500.
[0032] Understandably, the number of arc-shaped tubes 520 is one less than the number of balloons 500. The radius of the arc of the arc-shaped tube 520 is the same as or similar to the inner radius of the bite portion 100. The two ends of the arc-shaped tube 520 are connected to two adjacent balloons 500, thereby connecting all balloons 500. A connecting rod is fixed to the outside of the arc-shaped tube 520. The connecting rod is fixed to the end face of the bite portion 100 away from the pressure plate 200, thereby fixing the arc-shaped tube 520 to restrict the position of the two ends of the balloons 500.
[0033] One of the balloons 500 or one of the arc-shaped tubes 520 is connected to an air duct 510. The air duct 510 passes through the pressure plate 200 and is equipped with a switch interface 511. After opening the switch interface 511, the air duct 510 can be connected to the output end of a manual ball valve or an air valve, thereby allowing the balloon 500 to be inflated. In the unused state, the balloon 500 is in a flat state, which does not easily obstruct the passage of the rigid endoscope. When it is necessary to restrict the rigid endoscope, after inflating the balloon 500 to a certain extent, the position of the rigid endoscope can be restricted at that point. That is, the rigid endoscope can use the restricted position as a relatively stable fulcrum position for rotation or swinging, thereby precisely adjusting the operating position of one end of the rigid endoscope, thus preventing the rigid endoscope from shaking or being inaccurate in position during rotation or swinging, and improving the accuracy of rigid endoscope operation.
[0034] Two arc-shaped loops 530 are arranged side by side along the axial direction on one side of the occlusal portion 100. One end of the arc-shaped loop 530 is fixed to the outer periphery of the occlusal portion 100, and the other end is bent to form an arc-shaped ring. The air tube 510 can be embedded inside the arc-shaped loop 530 to prevent the air tube 510 from touching the patient's oral cavity and causing discomfort.
[0035] Both ends of the rotating sleeve 300 are configured with outwardly extending arc-shaped flared structures, that is, the diameters of the two ends of the rotating sleeve 300 gradually increase in the direction away from each other, to facilitate the insertion and operation of the rigid lens. In other embodiments, the flared structure may be provided only at one end of the rotating sleeve 300.
[0036] Both sides of the retaining ring 320 are integrally formed with hooks 321, the cross-section of which is L-shaped. Both sides of the pressure plate 200 are provided with slots 322, the cross-section of which is also L-shaped. When the hooks 321 are embedded in the slots 322, the retaining ring 320 can be fixed to the pressure plate 200 to stabilize the position of the rotating sleeve 300. In other embodiments, the retaining ring 320 can also be detachably mounted on the pressure plate 200 using a screw structure.
[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
