Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an ICU fiber bronchoscope which is easy to operate. Background Art

[0002] When using a fiber bronchoscope, medical staff can insert the fiber bronchoscope into the patient's trachea through the nasal cavity or oral cavity as needed. Before testing the patient, the patient is often given an anesthetic injection. However, the anesthetized patient will still bite his mouth unconsciously, which will cause the fiber bronchoscope to shake, which not only affects the operation of the medical staff, but also excessive shaking of the fiber bronchoscope can easily cause tracheal injury and bleeding.

[0003] Although the existing bite ring can limit the patient's oral movement, due to the large oral space, the patient's tongue will shake and tilt because the patient lies flat, and may even press against the introduced fiber bronchoscope, causing the fiber bronchoscope to swing left and right, causing inconvenience to medical staff and increasing the risk to the patient. In response to the above technical problems, the applicant has retrieved some prior art, such as the Chinese patent with patent publication number CN216628495U. When in use, the oral cushion is installed in the patient's mouth, and the fiber bronchoscope passes through the oral cushion. When the patient bites his mouth, the teeth are embedded in the bite groove, and the tongue pad presses against the tongue in the patient's mouth to prevent the tongue from shaking and cutting. However, the oral cushion will completely block the condition inside the patient's mouth in the patient's mouth. Medical staff cannot observe the condition inside the patient's mouth when performing fiber bronchoscope examination, so it is difficult for medical staff to adjust the position of the bronchoscope to align with the trachea. The position of the fiber bronchoscope needs to be adjusted multiple times, which increases the difficulty and time consumption of fiber bronchoscope examination. Summary of the invention

[0004] The purpose of the present invention is to provide an ICU fiber bronchoscope that is easy to operate, aiming to solve the technical problem in the prior art that the patient's oral cavity is blocked when the patient's tongue is fixed, making it difficult for medical staff to observe the internal condition of the patient's oral cavity.

[0005] The present invention is implemented as follows: an ICU fiber bronchoscope that is easy to operate includes two groups of connected bite blocks, a fiber bronchoscope body and a mounting frame, the two groups of bite blocks are provided with a moving bar on the side close to each other, and the bite block is provided with an adjustment component for adjusting the position of the moving bar, the moving bar passes through the bite block and a first limit plate is rotatably installed at one end of the moving bar, a side limit plate is fixedly installed on the first limit plate, and a second limit plate is fixedly installed at one end of the side limit plate away from the first limit plate, the mounting frame is detachably connected to the first limit plate and the second limit plate, and a guide component for guiding the moving path of the fiber bronchoscope body is provided on the mounting frame, the guide component includes a positioning cylinder and the fiber bronchoscope body passes through the positioning cylinder.

[0010] Further technical solution: The guide assembly also includes a slide plate, which is slidably mounted on the mounting frame. Both sides of the mounting frame are provided with slide grooves for mounting the slide plate. A sliding sleeve is slidably mounted on the slide plate, and the positioning cylinder is rotatably mounted on the sliding sleeve.

[0011] Further technical solution: the end of the positioning tube extending into the patient's mouth is connected to a metal deformable hose, and the end of the metal deformable hose away from the positioning tube is a conical structure and is provided with a through hole for the fiber bronchoscope body to pass through.

[0012] Further technical solution: an adjusting rod is threadedly connected to the sliding sleeve, the adjusting rod passes through the side wall of the sliding sleeve and is used in conjunction with the sliding plate, and the adjusting rod and the positioning cylinder are distributed along the moving direction of the sliding plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The patient's tongue is limited from both sides and ends of the patient's tongue by two sets of first limiting plates, two sets of second limiting plates and two sets of side limiting plates, so that the patient's tongue can be restricted to the area close to the lower jaw, avoiding the patient's tongue from moving randomly due to anesthesia during subsequent examinations. At the same time, the patient's teeth are supported by the bite block, and the patient's tongue is close to the lower jaw, avoiding blocking the opening between the patient's teeth, so that the inside of the patient's mouth is in an open state, avoiding blocking the patient's mouth, and medical staff can clearly observe the condition of the patient's mouth and the position of the trachea, which is convenient for subsequent examinations.

[0015] 2. The sliding sleeve is driven to move laterally by the adjusting rod, and the longitudinal position of the end of the metal deformable hose is adjusted by rotating the positioning tube, so that the end of the metal deformable hose is aligned with the position of the patient's tracheal opening, thereby realizing the positioning of the patient's tracheal opening, so that the fiber bronchoscope body can directly enter the patient's trachea from the positioning tube and the metal deformable hose, thereby improving the speed of the fiber bronchoscope body entering the trachea, avoiding positioning the patient's trachea through the fiber bronchoscope body, reducing the difficulty of the fiber bronchoscope body entering the patient's trachea, and improving the speed of detection. The positioning tube and the metal deformable hose are used to guide and wrap the movement of the fiber bronchoscope body, thereby avoiding collision and friction between the fiber bronchoscope body and the patient's oral cavity during movement, avoiding vomiting and other actions that affect the position of the fiber bronchoscope body due to friction, reducing the patient's discomfort during the examination, and minimizing the shaking of the fiber bronchoscope body caused by the patient's discomfort, thereby improving the stability and accuracy during the examination.

[0016] 3. The sliding sleeve is driven to move laterally by the adjusting rod, and the longitudinal position of the end of the metal deformable hose is adjusted by rotating the positioning cylinder, so that the metal deformable hose and the positioning cylinder deviate from the position of the uvula, thereby avoiding the positioning cylinder and the metal deformable hose from rubbing against the patient's uvula during movement, reducing the patient's discomfort, thereby reducing the number of patient's jaw movements and increasing the stability of the device installation.

[0017] 4. Since the bite block is bitten by the patient and the movable bar is fixed on the bite block, the first limit plate and the second limit plate are both in a fixed state. The mounting frame is supported by the first limit plate and the second limit plate, thereby ensuring the stability of the mounting frame installation, thereby improving the stability and accuracy of the subsequent positioning cylinder and the deformable metal hose during position adjustment, and at the same time ensuring the stability of the subsequent fiber bronchoscope when moving in the positioning cylinder and the deformable metal hose.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] In actual application of this embodiment, the patient opens his mouth, and two groups of bite blocks 1 are placed on two sides of the open area of ​​the patient's mouth, so that the patient's upper and lower teeth are respectively engaged in the bite grooves 3 on the upper and lower sides of the bite block 1. The patient's teeth are positioned by the bite grooves 3 to ensure that the bite block 1 is in a stable state after being bitten by the patient. At this time, the patient's mouth is opened by the two groups of bite blocks 1, and the connecting strip 2 is located in front of the patient's teeth, so as not to block the open area between the patient's upper and lower teeth. At this time, the bite block 1 is placed;

[0029] Then, the position of the moving bar 8 is adjusted by adjusting the adjustment component 24, so that the first limiting plate 10 moves to the position of the patient's tongue root, and the end of the side limiting plate 11 contacts the side of the patient's tongue. At this time, the doctor can use tweezers and other tools to push the side limiting plate 11 to rotate, so that the side limiting plate 11 contacts the side of the patient's tongue and the second limiting plate 12 moves to the top of the front end of the patient's tongue. At this time, the patient's tongue is limited from both sides and both ends of the patient's tongue by two groups of first limiting plates 10, two groups of second limiting plates 12 and two groups of side limiting plates 11. The side limiting plate 11 can maintain its position at any time when rotating through two groups of adsorbed first annular magnets 22 and second annular magnets 23, so that the patient's tongue can be limited to the area attached to the lower jaw, avoiding the patient's tongue from moving randomly due to anesthesia during subsequent examinations. At the same time, the patient's teeth are supported by the bite block 1, and the patient's tongue is close to the lower jaw, avoiding blocking the opening between the patient's teeth, so that the inside of the patient's mouth is in an open state, avoiding blocking the patient's mouth, and medical staff can clearly observe the condition of the patient's mouth and the position of the trachea, which is convenient for subsequent examinations;

[0030] After the patient's tongue is fixed, the mounting frame 13 is placed on the first limiting plate 10 and the second limiting plate 12, and the mounting frame 13 is adsorbed on the first limiting plate 10 and the second limiting plate 12 through the permanent magnet 14. Of course, the mounting frame 13 can also be fixed on the first limiting plate 10 and the second limiting plate 12 by other means such as screw fixing or plugging. At this time, the positioning cylinder 19 is adjusted to move through the guide component 25 so that the positioning cylinder 19 enters the patient's oral cavity, and the position of the positioning cylinder 19 is adjusted so that the end of the positioning cylinder 19 is aligned with the patient's trachea position. Subsequently, the fiber bronchoscope body 20 is inserted into the positioning cylinder 19. After the fiber bronchoscope body 20 passes through the positioning cylinder 19, it can enter the patient's trachea for inspection. After the inspection is completed, the fiber bronchoscope body 20 is pulled out, and then the restriction on the patient's tongue is released, and finally the bite block 1 is taken out.

[0031] like Figure 1-Figure 3 As shown, an ICU fiber bronchoscope that is easy to operate is provided by the present invention. The adjustment component 24 includes a through slot 4 and a support block 5. The through slot 4 is opened on the bite block 1 and the moving bar 8 is slidably installed in the through slot 4. The support block 5 is fixedly installed on the bite block 1 and is located at one end of the through slot 4. A lifting plate 6 is slidably installed on the support block 5. A connecting sleeve 7 is fixedly installed on one end of the lifting plate 6 close to the moving bar 8, and the connecting sleeve 7 is slidably connected to the moving bar 8.

[0032] When this embodiment is actually used, the movable bar 8 is pushed to drive the first limiting plate 10 to move into the patient's oral cavity so that the first limiting plate 10 moves to the patient's tongue root position. After the end of the side limiting plate 11 contacts the side of the patient's tongue, the fixing screw is rotated to fix the connecting sleeve 7 and the movable bar 8. At this time, the movable bar 8 is moved downward, so that the first limiting plate 10 contacts the upper surface of the patient's tongue and presses the patient's tongue downward. Then, the position of the lifting plate 6 is fixed by the fixing screw, thereby completing the adjustment of the position of the movable bar 8. Repeat the above steps to adjust the position of the movable bar 8 on the other side so that the first limiting plate 10 is in a suitable position.

[0033] like Figure 1 , Figure 3 , Figure 6 As shown, an ICU fiber bronchoscope that is easy to operate is provided by the present invention. The guide assembly 25 also includes a slide plate 16, which is slidably mounted on the mounting frame 13. Both sides of the mounting frame 13 are provided with slide grooves 15 for mounting the slide plate 16. A moving screw that drives the slide plate 16 to move is rotatably mounted on the mounting frame 13. A sliding sleeve 17 is slidably mounted on the slide plate 16, and a positioning cylinder 19 is rotatably mounted on the sliding sleeve 17. The positioning cylinder 19 is mounted on the sliding sleeve 17 through a damping shaft.

[0034] Specifically, one end of the positioning tube 19 extending into the patient's oral cavity is connected to a metal deformable hose 21 , and one end of the metal deformable hose 21 away from the positioning tube 19 is a conical structure and is provided with a through hole for the fiber bronchoscope body 20 to pass through.

[0035] Specifically, an adjusting rod 18 is threadedly connected to the sliding sleeve 17 . The adjusting rod 18 passes through the side wall of the sliding sleeve 17 and is used in conjunction with the sliding plate 16 . The adjusting rod 18 and the positioning cylinder 19 are distributed along the moving direction of the sliding plate 16 .

[0036] When the present embodiment is actually used, the bending degree and bending shape of the metal deformable hose 21 are adjusted according to the internal conditions of the patient's oral cavity. The slide plate 16 is driven to move along the mounting frame 13 by moving the screw so that the slide plate 16 drives the positioning tube 19 and the metal deformable hose 21 to enter the patient's oral cavity and move to the patient's trachea position. When the metal deformable hose 21 moves to the position of the uvula, the sliding sleeve 17 is driven to move laterally by the adjusting rod 18, and the longitudinal position of the end of the metal deformable hose 21 is adjusted by rotating the positioning tube 19, so that the metal deformable hose 21 and the positioning tube 19 deviate from the position of the uvula, thereby avoiding the positioning tube 19 and the metal deformable hose 21 from rubbing against the patient's uvula during the movement, reducing the patient's discomfort, thereby reducing the number of movements of the patient's lower jaw, and increasing the stability of the device installation. Then, the slide plate 16 is pushed to continue to move, and the lateral position of the end of the metal deformable hose 21 is adjusted by the sliding sleeve 17 according to the position of the trachea, and the longitudinal position of the end of the metal deformable hose 21 is adjusted by rotating the positioning tube 19, so that the end of the metal deformable hose 21 is aligned with the patient's tracheal opening position. At this time, the adjusting rod 18 is rotated. The adjusting rod 18 is made to collide with the slide plate 16, thereby achieving the fixation of the sliding sleeve 17 and the metal deformable hose 21. Subsequently, the fiber bronchoscope body 20 passes through the positioning tube 19 and the metal deformable hose 21 and then can be inserted into the patient's trachea for inspection, thereby achieving the positioning of the patient's tracheal orifice, so that the fiber bronchoscope body 20 can directly enter the patient's trachea from the positioning tube 19 and the metal deformable hose 21, thereby improving the speed of the fiber bronchoscope body 20 entering the trachea, avoiding the positioning of the patient's trachea by the fiber bronchoscope body 20, and reducing The difficulty of the fiber bronchoscope body 20 entering the patient's trachea is reduced, the speed of detection is improved, and the movement of the fiber bronchoscope body 20 is guided and wrapped by the positioning tube 19 and the metal deformable hose 21, thereby avoiding the fiber bronchoscope body 20 from colliding and rubbing against the inside of the patient's mouth during movement, avoiding vomiting and other actions that affect the position of the fiber bronchoscope body 20 due to friction, reducing the patient's discomfort during the examination, minimizing the shaking of the fiber bronchoscope body 20 caused by the patient's discomfort, and improving the stability and accuracy during the examination.
