Description

Technical Field

[0001] The present invention relates to the technical field of biopsy devices, and in particular to a biopsy device for pathology. Background Art

[0002] When an abnormal mass or lesion appears in the throat and imaging tests such as CT and MRI cannot provide a clear diagnosis, a biopsy is needed to obtain a tissue sample for pathological examination to confirm whether it is a malignant tumor. If hoarseness persists for more than two to three weeks without an obvious cause such as a cold, a biopsy is needed to rule out serious diseases such as laryngeal cancer and a biopsy is required to confirm the diagnosis.

[0003] However, the existing laryngeal biopsy device needs to enter the patient's mouth and then be placed in the patient's throat for biopsy sampling during use. When the existing related surgical instruments enter the mouth, there is only a tongue depressor to protect the patient's tongue, and the instrument may still accidentally touch the patient's upper oral wall or oral side wall when passing through the patient's mouth. At the same time, when the instrument enters the throat from the mouth, the patient needs to keep his mouth open. However, when the instrument enters the patient's mouth, it is difficult for the patient to maintain a sufficient opening of the mouth due to contact stimulation, which increases the difficulty of laryngeal biopsy and makes the work efficiency of biopsy low. Therefore, the present application provides a biopsy device for pathology to meet the needs. Summary of the Invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up the oral protection mechanism and the guide lubrication mechanism, not only can the inner wall of the oral cavity be fully protected, but the patient's tongue can be flattened while minimizing the contact between the structure and the sensitive parts of the tongue, thereby reducing the discomfort of the patient such as dry hiccups when the device is used, and the oral protection mechanism can also be used to quickly guide and limit the laryngoscope body, and at the same time assist the patient to open his mouth, thereby facilitating the medical staff to insert the relevant instruments for biopsy into the throat through the patient's mouth for sampling, and the guide lubrication mechanism can also be used to guide the laryngoscope body so that the laryngoscope body can quickly enter the patient's throat, and the outer wall of the laryngoscope body can be lubricated during the period when the laryngoscope body enters the throat, thereby reducing the irritation of the outer wall of the laryngoscope body to the patient's throat, and the coordinated use of the structures further reduces the patient's discomfort, and the structure is simple, which is convenient for medical staff to use and operate, thereby effectively increasing the work efficiency of laryngeal biopsy in the pathology department, and the practicality of the device is good.

[0018] By providing a top auxiliary piece and a bottom auxiliary piece in the oral protection mechanism, not only can the top auxiliary piece and the bottom auxiliary piece be affected by the restorative force generated by the deformation after being placed in the patient's mouth, but they also have a tendency to move away from each other, thereby protecting the upper and lower walls of the patient's mouth while assisting the patient to open his mouth to an appropriate size. In addition, by providing the first weakened portion and the second weakened portion, the top auxiliary piece can be deformed first from the first weakened portion under the action of force, and the bottom auxiliary piece can be deformed first from the second weakened portion under the action of force, thereby facilitating the bending of the connecting piece, the top auxiliary piece, the bottom auxiliary piece, the concave piece and the end piece into a U shape during use, and facilitating the placement of the integrated structure composed of the connecting piece, the top auxiliary piece, the bottom auxiliary piece, the concave piece and the end piece in the patient's mouth. The coordinated use of the structures effectively makes the use of the oral protection mechanism better, and the structure is simple and easy to use.

[0019] By arranging a tongue depressing auxiliary piece, a concave piece and an end piece in the oral protection mechanism, it can not only be placed in the patient's oral cavity, so that the connecting piece is located on the side close to the patient's mouth, and the patient's upper teeth and lower teeth are respectively placed in a concave piece on the top auxiliary piece and a concave piece on the bottom auxiliary piece, and the two end pieces are respectively against the patient's upper lip and lower lip, the coordinated use of the structures protects the patient's entire oral cavity, and while the tongue depressing auxiliary piece limits the patient's tongue, an anti-pressure groove is provided on the bottom side of the tongue depressing auxiliary piece close to the connecting piece, which effectively reduces the contact between the tongue depressing auxiliary piece and the posterior root of the tongue during use, thereby reducing the occurrence of discomfort such as dry hiccups on the patient's tongue, and the coordinated use of the structures effectively makes the oral protection mechanism more effective, and the structure is simple and easy to use.

[0020] By providing a support plate in the oral protection mechanism, not only can the support of the connecting plate, the top auxiliary plate, the bottom auxiliary plate, the concave plate and the end plate be enhanced by the setting of the support plate, but the support plate can also be used to guide the insertion of the laryngoscope body so that the laryngoscope body can pass through the guide groove and enter the patient's throat, thereby accurately aligning with the patient's throat, preventing the laryngoscope body from deviating and scraping the patient's throat, causing strong discomfort, and further limiting the two sides of the laryngoscope body by using the support plate, and preventing the laryngoscope body from accidentally touching the inner walls of the patient's mouth on both sides, while squeezing the laryngoscope body inward, guiding and limiting the laryngoscope body, and buffering the speed at which it enters the oral cavity, so that the laryngoscope body can slowly enter the throat position required for biopsy, further reducing the irritation of the laryngoscope body to the throat.

[0021] By providing a guide sheet in the guide lubrication mechanism, not only can the first guide portion on the guide sheet be used to guide the laryngoscope body when inserted into the oral cavity and throat, but also before the guide sheet is used, a sufficient amount of physiological saline is injected into the storage chamber from the injection port in advance. When the guide sheet is in a natural state without being subjected to external force, it is in a sealed state near the opening, and the sealing block is stuck in the sealing groove, so that the physiological saline placed in the storage chamber will not flow out. When the laryngoscope body passes through the guide sheet along the guidance of the first guide portion, the side of the guide sheet close to the first guide portion is squeezed and deformed in a direction away from the center of the guide sheet. When the laryngoscope body passes through the convex portion, the convex portion is squeezed and deformed in a direction away from the center of the guide sheet, thereby opening the opening. At this time, the opening is aligned with the outer wall of the end of the laryngoscope body, and the physiological saline in the storage chamber flows out from the opening and is smeared on the outer wall of the laryngoscope body. After the opening is opened, the laryngoscope body is continuously inserted into the patient's throat. During this period, the outer wall of the laryngoscope body is disinfected and lubricated by the physiological saline in the storage chamber, and the coordinated use of the structures effectively makes the use effect of the guide lubrication mechanism better, and the structure is simple and easy to use.

[0022] By providing a third weakened portion, a convex portion and a sealing block in the guide lubrication mechanism, not only can the convex portion be more easily and quickly deformed in a direction away from the center position of the guide piece when squeezed, thereby facilitating the storage of the required physiological saline in the storage chamber, a second guide portion is provided on the side of the third weakened portion close to the sealing block, and the edge of the side of the guide piece close to the sealing groove is arc-shaped. The guidance of the second guide portion allows the two ends of the guide piece close to the opening to approach faster, so that the sealing block can be quickly stuck in the sealing groove, and the practicality of the guide lubrication mechanism is improved through the coordinated use of the structures, and the coordinated use of the structures effectively makes the use effect of the guide lubrication mechanism better, and the structure is simple and easy to use.

[0023] In summary, the present device can not only comprehensively protect the patient's oral cavity during the laryngeal biopsy sampling process through the coordinated use of the oral protection mechanism, the guide lubrication mechanism and the various components therein, but also has a good guiding, buffering and lubricating effect on the laryngoscope body, thereby facilitating the sampling operation of medical staff while increasing the comfort of the patient. In addition, the present device has a simple structure, is easy and quick to use, and has a low production cost, good practicality and is easy to promote and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figures 1 to 8As shown, an embodiment of the present invention provides a biopsy device for pathology, comprising a biopsy sampling forceps body 1, a laryngoscope body 2 being mounted on one side of the biopsy sampling forceps body 1, a connecting piece 3 being sleeved on the bottom of the laryngoscope body 2, a guide groove 4 being adapted to the shape of the bottom of the laryngoscope body 2 being opened in the middle of the connecting piece 3; an oral protection mechanism, the oral protection mechanism being used to protect the patient's oral cavity and assist the laryngoscope body 2 in sampling, the oral protection mechanism being connected to the connecting piece 3; a guide lubrication mechanism, the guide lubrication mechanism being used to assist the laryngoscope body 2 in being inserted into the patient's throat, the guide lubrication mechanism being connected to the connecting piece 3. By providing an oral protection mechanism, the device can provide all-round protection for the inner wall of the oral cavity during use, and while flattening the patient's tongue, minimize contact between the structure and the sensitive parts of the tongue, thereby reducing discomfort such as dry hiccups caused by the patient during use. The oral protection mechanism can also be used to quickly guide and limit the laryngoscope body 2, assisting the patient in opening his mouth, thereby facilitating medical personnel to insert relevant instruments for biopsy into the throat through the patient's oral cavity for sampling. The guide lubrication mechanism can be used to guide the laryngoscope body 2 so that the laryngoscope body 2 can quickly enter the patient's throat, and lubricate the outer wall of the laryngoscope body 2 during the period of entry, thereby reducing irritation to the patient's throat by the outer wall of the laryngoscope body 2. The coordinated use of the structures further reduces the patient's discomfort, and the structure is simple, making it easy for medical personnel to use and operate, thereby effectively increasing the efficiency of laryngeal biopsy in the pathology department, and the device has good practicality. The above-mentioned biopsy sampling forceps body 1 and laryngoscope body 2 are existing mature technologies, so their working principles and specific structural compositions are not described in detail here, and the specific structural compositions and working principles of the above-mentioned oral protection mechanism and guide lubrication mechanism are described in detail below.

[0042] like Figures 3 to 8 As shown, the oral protection mechanism includes a top auxiliary piece 6 installed on the top of the connecting piece 3, a bottom auxiliary piece 7 is fixedly connected to the bottom of the connecting piece 3, a tongue depressing auxiliary piece 10 is installed at the bottom of the bottom auxiliary piece 7, and a groove is provided at the bottom of the bottom auxiliary piece 7 to match the tongue depressing auxiliary piece 10. The tongue depressing auxiliary piece 10 does not fit the bottom of the bottom auxiliary piece 7 in a natural state. Figure 4 As shown, a support sheet 13 is installed between the top auxiliary sheet 6 and the bottom auxiliary sheet 7, and three branches are provided on the support sheet 13, such as Figure 5As shown, one of the branches is fixedly connected to the outer wall of one side of the connecting piece 3, and the other two branches are fixedly connected to the outer walls of one side of the top auxiliary piece 6 and the bottom auxiliary piece 7 respectively. The cross-section of the support piece 13 is close to a triangle, and the support piece 13 is an arc-shaped structure convex in the direction of the guide groove 4. The top auxiliary piece 6 and the bottom auxiliary piece 7 are fixedly connected to the side away from the connecting piece 3 with a concave piece 16, and the concave piece 16 is fixedly connected to the side away from the connecting piece 3 with an end piece 17. The connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 are an integrated structure. The concave piece 16 is provided to facilitate the placement of the patient's teeth therein, and the end pieces 17 are provided to facilitate the medical staff to press the two end pieces 17 by hand, and the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 are bent into a U shape, and then placed in the patient's oral cavity, so that the connecting piece 3 is located on the side close to the patient's mouth, and the patient's upper teeth and lower teeth are respectively placed in a concave piece 16 on the top auxiliary piece 6 and a concave piece 16 on the bottom auxiliary piece 7, and the two end pieces 17 are respectively against the patient's upper lip and lower lip.

[0043] The coordinated use of the above structures can protect the entire oral cavity of the patient, and after the top auxiliary piece 6 and the bottom auxiliary piece 7 are placed in the patient's oral cavity, they are affected by the restorative elastic force generated by the deformation, and they tend to move away from each other, thereby protecting the upper and lower walls of the patient's oral cavity while assisting the patient to open his mouth to an appropriate size, thereby facilitating the placement of related sampling instruments such as the biopsy sampling forceps body 1 and the laryngoscope body 2 in the patient's oral cavity and throat. The setting of the support piece 13 enhances the support of the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17. The integrated structure composed of the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 is used to guide the insertion of the laryngoscope body 2, so that the laryngoscope body 2 can pass through the guide groove 4 and enter the patient's throat, thereby accurately aligning with the patient's throat, preventing the laryngoscope body 2 from deviating and scraping the patient's throat, causing strong discomfort, and further limiting the two sides of the laryngoscope body 2 by the support piece 13 to prevent the laryngoscope body 2 from accidentally hitting the inner walls of the patient's mouth on both sides. At the same time, the two oppositely arranged support pieces 13 squeeze the laryngoscope body 2 inward, guiding and limiting the laryngoscope body 2 while also buffering the speed of its entry into the oral cavity, so that the laryngoscope body 2 can slowly enter the required laryngeal position for biopsy, further reducing the stimulation of the laryngoscope body 2 on the throat, and the coordinated use of the structures makes the use of the device more convenient while also increasing the safety of the device. The production cost of the device is low, which is convenient for promotion and use.

[0044] A first weakened portion 8 is provided on one side of the top auxiliary piece 6 close to the connecting piece 3, and a second weakened portion 9 is provided on one side of the bottom auxiliary piece 7 close to the connecting piece 3. By setting the first weakened portion 8 and the second weakened portion 9, the top auxiliary piece 6 can be deformed first from the first weakened portion 8 under the action of force, and the bottom auxiliary piece 7 can be deformed first from the second weakened portion 9 under the action of force, thereby facilitating the bending of the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 into a U shape when in use, so that the integrated structure composed of the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 can be placed on the patient's side. In the mouth, reinforcement strips 15 are equidistantly installed on the side of the top auxiliary piece 6 close to the first weakened part 8 and the side of the bottom auxiliary piece 7 close to the second weakened part 9. The reinforcement strips 15 are made of steel wire. The reinforcement strips 15 can enhance the deformation ability and strength of the top auxiliary piece 6 and the bottom auxiliary piece 7, so that when the top auxiliary piece 6 close to the first weakened part 8 and the bottom auxiliary piece 7 close to the second weakened part 9 are deformed during repeated use, they will not be easily bent and damaged due to excessive bending, thereby increasing the service life of the device. The coordinated use of the structures further makes the use effect of the oral protection mechanism better, and the structure is simple, which is convenient for medical staff to use and operate.

[0045] like Figures 1 to 8As shown, a recess 18 is provided on one side of the support piece 13 close to the center of the guide groove 4. The recess 18 is used to make the support piece 13 have a tendency to approach the center of the guide groove 4, so that when in use, the two oppositely arranged support pieces 13 are close to the outer wall of the laryngoscope body 2, which has a limiting and guiding effect on the laryngoscope body 2, thereby facilitating the placement of the laryngoscope body 2 in the desired position. A slot 14 is provided in the middle of the side of the support piece 13 away from the connecting piece 3, and the slot 14 is used to make the support piece 13 connected to the two top auxiliary pieces 6 and the bottom auxiliary pieces 7 respectively. The branches are in a state of being away from each other under the action of force, so that the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 have a good rebound tendency when they are bent into a U shape, thereby assisting the patient to open his mouth, reducing the pressure on the patient to keep his mouth open, and thus increasing the patient's comfort during laryngeal biopsy. The top auxiliary piece 6 is provided with a second lightweight groove 12 at equal distances, which reduces the mass of the top auxiliary piece 6 and increases the deformation capacity of the top auxiliary piece 6. The bottom auxiliary piece 7, the tongue-pressing auxiliary piece 10 and the end piece 17 are all provided with a first lightweight groove 12 at equal distances. 1, not only reduces the mass of the bottom auxiliary piece 7, the tongue depressing auxiliary piece 10, and the end piece 17, but also increases the deformation ability of the bottom auxiliary piece 7, the tongue depressing auxiliary piece 10, and the end piece 17. The bottom of the tongue depressing auxiliary piece 10 is close to the side of the connecting piece 3 and is provided with an anti-pressure groove 28, which effectively reduces the contact between the tongue depressing auxiliary piece 10 and the back root of the tongue when in use, thereby reducing the occurrence of discomfort such as dry hiccups on the patient's tongue. The top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 are all made of rubber material, and the outer walls of the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 are They are all arc-shaped, and the surface of the rubber material is relatively soft. The arc-shaped design of the edge of the structure ensures that the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 will not scratch the inner wall of the patient's mouth when they come into contact with the patient's mouth, and make the patient feel more comfortable. The support piece 13 is made of plastic material. The support piece 13 made of plastic material has good support for the top auxiliary piece 6, the bottom auxiliary piece 7 and the connecting piece 3, and the plastic material itself has good deformation ability, so that the support piece 13 can undergo a certain elastic deformation under the action of external force.

[0046] like Figures 1 to 8As shown, the guide lubrication mechanism includes a guide piece 5 installed on the connecting piece 3, an opening 20 is provided on one side of the guide piece 5 close to the center position of the connecting piece 3, a storage chamber 21 is provided in the guide piece 5, a first guide portion 19 is provided on the side of the guide piece 5 away from the connecting piece 3, a convex portion 24 is fixedly connected to the inner wall of the guide piece 5 close to the connecting piece 3, a sealing groove 26 is provided on the inner wall of the guide piece 5 close to the convex portion 24, a sealing block 25 that is adapted to the shape of the sealing groove 26 is provided on the inner wall of the guide piece 5, and a liquid injection port 27 is provided on the inner wall of the guide piece 5. The laryngoscope body 2 is inserted into the oral cavity and throat by utilizing the first guide portion 19 on the guide piece 5, and before the guide piece 5 is used, a sufficient amount of physiological saline is injected into the storage chamber 21 from the liquid injection port 27 in advance. When the guide piece 5 is in a natural state without being subjected to external force, the portion near the opening 20 is in a sealed state, and the sealing block 25 is stuck in the sealing groove 26, so that The physiological saline solution placed in the storage chamber 21 will not flow out. When the laryngoscope body 2 passes through the guide piece 5 along the guidance of the first guide part 19, the side of the guide piece 5 close to the first guide part 19 is squeezed and deformed in the direction away from the center of the guide piece 5. When the laryngoscope body 2 passes through the convex part 24, the convex part 24 is squeezed and deformed in the direction away from the center of the guide piece 5, thereby opening the opening 20. At this time, the opening 20 is aligned with the outer wall of the end of the laryngoscope body 2, and the physiological saline solution in the storage chamber 21 flows out from the opening 20 and is smeared on the outer wall of the laryngoscope body 2. After the opening 20 is opened, the laryngoscope body 2 is continuously inserted into the patient's throat. During this period, the outer wall of the laryngoscope body 2 is disinfected and lubricated by the physiological saline solution in the storage chamber 21, so that when the end of the laryngoscope body 2 contacts the patient's throat, it can effectively reduce the stimulation to the throat, thereby reducing the patient's discomfort. The coordinated use of the structures further makes the use effect of the device better, and the structure is simple, and it is convenient and quick to use.

[0047] A third weakened portion 23 is provided on one side of the guide piece 5 close to the connecting piece 3, so that the protrusion 24 can be deformed more easily and quickly in the direction away from the center position of the guide piece 5 when squeezed. The guide piece 5 is made of rubber material, and the rubber material has good deformation ability. When the guide piece 5 is not subjected to external force, it has a tendency to collapse inward, so that the sealing block 25 and the sealing groove 26 are squeezed against each other, and then the guide piece 5 is squeezed inward by its own tendency to deform inward without being subjected to external force, so that the opening 20 can be sealed, thereby facilitating the storage of the required saline solution in the storage chamber 21. The third weakened portion 23 is provided on the side of the guide piece 5 close to the connecting piece 3, so that the protrusion 24 can be deformed more easily and quickly in the direction away from the center position of the guide piece 5 when squeezed. A second guide portion 22 is provided on the side of the portion 23 close to the sealing block 25, and the edge of the guide piece 5 close to the sealing groove 26 is arc-shaped. The second guide portion 22 is used to guide the two ends of the guide piece 5 close to the opening 20 to be closer faster, so that the sealing block 25 can be quickly inserted into the sealing groove 26. The shape of the guide piece 5 is adapted to the shape of the laryngoscope body 2, so that the guide piece 5 can better guide and lubricate the laryngoscope body 2, and the practicality of the guide lubrication mechanism is improved through the coordinated use of the structures, and the structure is relatively simple, which is convenient for medical staff to use and operate.

[0048] The workflow of the technical solution provided by the present invention is as follows:

[0049] When in use, first inject a sufficient amount of physiological saline into the storage chamber 21 from the injection port 27. When the guide plate 5 is in a natural state without being subjected to external forces, it is in a sealed state close to the opening 20, and the sealing block 25 is stuck in the sealing groove 26, so that the physiological saline is placed in the storage chamber 21 and will not flow out. Then the medical staff presses the two end pieces 17 in the approaching direction with one hand, bends the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17 into a U shape, and then places it and the various components thereon in the patient's oral cavity, so that the connecting piece 3 is located on the side close to the patient's mouth, so that the patient's upper teeth and lower teeth are placed in a concave piece 16 on the top auxiliary piece 6 and a concave piece 16 on the bottom auxiliary piece 7 respectively, and the two end pieces 17 are respectively against the patient's upper lip and lower lip, and the two oppositely arranged supporting pieces 13 support and limit the connecting piece 3, the top auxiliary piece 6, the bottom auxiliary piece 7, the concave piece 16 and the end piece 17. The coordinated use of the structures protects the entire oral cavity of the patient. After the top auxiliary piece 6 and the bottom auxiliary piece 7 are placed in the patient's oral cavity, they are affected by the restorative elastic force generated by the deformation, and they have a tendency to move away from each other, thereby protecting the upper and lower walls of the patient's oral cavity while assisting the patient to open his mouth to an appropriate size.

[0050] Then the laryngoscope body 2 is passed through the patient's oral cavity, and the end piece 17 is first used to preliminarily guide the laryngoscope body 2. As the laryngoscope body 2 enters the patient's oral cavity deeper, the end of the laryngoscope body 2 contacts the support piece 13, and the support piece 13 is used to further guide the laryngoscope body 2. Then, as the laryngoscope body 2 is further inserted, the end of the laryngoscope body 2 contacts the guide piece 5, and then the guide piece 5 is used to finally limit and guide the end of the laryngoscope body 2, so that the laryngoscope body 2 can pass through the guide groove 4 and enter the patient's throat, thereby accurately aligning with the patient's throat and preventing the laryngoscope body 2 from deviating and scraping the patient's throat, causing strong discomfort. In the process of the laryngoscope body 2 passing through the patient's oral cavity, the support piece 13 further limits the two sides of the laryngoscope body 2, and also effectively prevents the laryngoscope body 2 from accidentally touching the inner walls of the patient's oral cavity on both sides, and at the same time squeezes the laryngoscope body 2 inward, which not only guides and limits the laryngoscope body 2, but also can prevent it from entering The speed of the oral cavity is buffered, so that the laryngoscope body 2 can slowly enter the throat position required for biopsy, further reducing the stimulation of the laryngoscope body 2 to the throat, and when the laryngoscope body 2 passes through the guide piece 5 along the guidance of the first guide part 19 on the guide piece 5, the side of the guide piece 5 close to the first guide part 19 is squeezed and deformed in the direction away from the center of the guide piece 5, and when the laryngoscope body 2 passes through the convex part 24, the convex part 24 is squeezed and deformed in the direction away from the center of the guide piece 5, thereby opening the opening 20. At this time, the opening 20 is aligned with the outer wall of the end of the laryngoscope body 2, and the physiological saline in the storage chamber 21 flows out from the opening 20 and is smeared on the outer wall of the laryngoscope body 2. After the opening 20 is opened, the laryngoscope body 2 is continuously inserted into the patient's throat. During this period, the outer wall of the laryngoscope body 2 is disinfected and lubricated by the physiological saline in the storage chamber 21, so that when the end of the laryngoscope body 2 contacts the patient's throat, it can effectively reduce the stimulation to the throat, thereby reducing the patient's discomfort.
