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 larynx 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 and there is no obvious cause such as a cold, a biopsy is needed to rule out serious diseases such as laryngeal cancer, and a biopsy is needed 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 one tongue depressor to protect the patient's tongue, and the instrument passing through the patient's mouth may still accidentally touch the patient's oral upper wall or oral side wall. At the same time, when the instrument enters the throat from the mouth, the patient needs to keep his mouth open, but when the instrument enters the patient's mouth, it is difficult for the patient to continue to keep the mouth open enough 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 also 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 such as dry hiccups caused by the patient 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, it can also assist the patient to open his mouth, thereby facilitating medical staff to insert 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 stimulation 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 practicability 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 elastic force generated by the deformation after being placed in the patient's oral cavity, and 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 a suitable size, and 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, and the coordinated use of the structures effectively makes the use effect 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 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 when in 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 use effect of the oral protection mechanism better, and the structure is simple and easy to use.

[0020] By providing a support sheet in the oral protection mechanism, not only can the support of the connecting sheet, the top auxiliary sheet, the bottom auxiliary sheet, the concave sheet and the end sheet be enhanced by the setting of the support sheet, but the insertion of the laryngoscope body can be guided by the support sheet so that the laryngoscope body can pass through the guide groove and enter the patient's throat, thereby accurately aligning the patient's throat and preventing the laryngoscope body from deviating and causing strong discomfort by scraping the patient's throat. The support sheet is used to further limit the two sides of the laryngoscope body to prevent the laryngoscope body from accidentally hitting the inner walls of the patient's mouth on both sides, and at the same time, the laryngoscope body is squeezed inwardly, which not only guides and limits the laryngoscope body, but also buffers the speed at which it enters the oral cavity, so that the laryngoscope body can slowly enter the desired throat position for biopsy, further reducing the stimulation 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 to be inserted into the oral cavity and the throat, but also before the guide sheet is used, a sufficient amount of saline is injected into the storage cavity 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 clamped in the sealing groove, so that the saline placed in the storage cavity 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 saline in the storage cavity 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 saline in the storage cavity, 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 two ends of the guide piece close to the opening can be closer to each other more quickly by utilizing the guidance of the second guide portion, so that the sealing block can be quickly stuck in the sealing groove, and the practicality of the guide lubrication mechanism is better 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 device can not only comprehensively protect the patient's oral cavity during laryngeal biopsy sampling through the coordinated use of the oral protection mechanism and 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 patient's comfort. In addition, the device has a simple structure, is easy and quick to use, has a low production cost, is practical, 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, including a biopsy sampling forceps body 1, a laryngoscope body 2 is installed on one side of the biopsy sampling forceps body 1, a connecting piece 3 is sleeved on the bottom of the laryngoscope body 2, and a guide groove 4 adapted to the shape of the bottom of the laryngoscope body 2 is opened in the middle of the connecting piece 3; an oral protection mechanism, the oral protection mechanism is used to protect the patient's oral cavity and assist the laryngoscope body 2 in sampling, and the oral protection mechanism is connected to the connecting piece 3; the guide lubrication mechanism is used to assist the laryngoscope body 2 in inserting into the patient's throat, and the guide lubrication mechanism is connected to the connecting piece 3. By setting up an oral protection mechanism, the device can provide all-round protection for the inner wall of the oral cavity when in use, and while flattening the patient's tongue, minimize the contact between the structure and the sensitive part of the tongue, thereby reducing the discomfort caused by the device to the patient such as dry hiccups when in use; the oral protection mechanism can also be used to quickly guide and limit the laryngoscope body 2, assist the patient to open his mouth, and facilitate the medical staff to insert the relevant instruments for biopsy into the throat through the patient's mouth 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 the outer wall of the laryngoscope body 2 can be lubricated during the period when the laryngoscope body 2 enters the throat, thereby reducing the stimulation of the outer wall of the laryngoscope body 2 to the patient's throat. The coordinated use of the structures further reduces the discomfort of the patient, and the structure is simple, which is convenient for the use and operation of medical staff, thereby effectively increasing the work efficiency of laryngeal biopsy in the pathology department, and the practicability of the device is good. 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 sheet 6 installed on the top of the connecting sheet 3, a bottom auxiliary sheet 7 is fixedly connected to the bottom of the connecting sheet 3, a tongue depressing auxiliary sheet 10 is installed at the bottom of the bottom auxiliary sheet 7, and a groove that matches the tongue depressing auxiliary sheet 10 is opened at the bottom of the bottom auxiliary sheet 7. The tongue depressing auxiliary sheet 10 does not fit the bottom of the bottom auxiliary sheet 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 arranged 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 side of the concave piece 16 away from the connecting piece 3 is fixedly connected to the 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, so as to bend 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 place it in the patient's oral cavity, so that the connecting piece 3 is located on the side close to the patient's mouth, 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 sheet 6 and the bottom auxiliary sheet 7 are placed in the patient's oral cavity, they tend to move away from each other due to the influence of the restorative elastic force generated by the deformation, thereby protecting the upper and lower walls of the patient's oral cavity while assisting the patient to open his mouth to a suitable 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 the patient's throat and preventing the laryngoscope body 2 from deviating and causing strong discomfort caused by scraping the patient's throat. The support piece 13 is used to further limit the two sides of the laryngoscope body 2 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 inwardly, which not only guides and limits the laryngoscope body 2, but also buffers the speed at which it enters the oral cavity, so that the laryngoscope body 2 can slowly enter the desired laryngeal position for biopsy, further reducing the stimulation of the laryngoscope body 2 to the throat. The coordinated use of the structures makes the use of the device more convenient while 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 sheet 6 close to the connecting sheet 3, and a second weakened portion 9 is provided on one side of the bottom auxiliary sheet 7 close to the connecting sheet 3. The first weakened portion 8 and the second weakened portion 9 are arranged so that the top auxiliary sheet 6 can be deformed first from the first weakened portion 8 under the action of force, and the bottom auxiliary sheet 7 can be deformed first from the second weakened portion 9 under the action of force, so that the connecting sheet 3, the top auxiliary sheet 6, the bottom auxiliary sheet 7, the concave sheet 16 and the end sheet 17 can be bent into a U shape during use, so that the integrated structure composed of the connecting sheet 3, the top auxiliary sheet 6, the bottom auxiliary sheet 7, the concave sheet 16 and the end sheet 17 can be placed on the patient's side. In the mouth, reinforcing strips 15 are equidistantly installed on the side of the top auxiliary piece 6 close to the first weakened portion 8 and the side of the bottom auxiliary piece 7 close to the second weakened portion 9. The reinforcing strips 15 are made of steel wire. The deformation ability and strength of the top auxiliary piece 6 and the bottom auxiliary piece 7 can be enhanced through the arrangement of the reinforcing strips 15, so that when the top auxiliary piece 6 close to the first weakened portion 8 and the bottom auxiliary piece 7 close to the second weakened portion 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 concave portion 18 is provided on one side of the support sheet 13 close to the center of the guide groove 4. The concave portion 18 is used to make the support sheet 13 have a tendency to approach the center of the guide groove 4, so that when in use, the two oppositely arranged support sheets 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 laryngoscope body 2 to be placed in a desired position. A groove 14 is provided in the middle of one side of the support sheet 13 away from the connecting sheet 3, and the groove 14 is used to make the support sheet 13 respectively connected to the two top auxiliary sheets 6 and the bottom auxiliary sheets 7. The branches are moved 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 bent into a U shape, thereby assisting the patient to open his mouth and reducing the pressure on the patient to keep his mouth open, thereby increasing the patient's comfort during laryngeal biopsy. The top auxiliary piece 6 is provided with second lightweight grooves 12 at equal intervals, 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 provided with first lightweight grooves 12 at equal intervals. 1, not only the mass of the bottom auxiliary sheet 7, the tongue depressing auxiliary sheet 10, and the end sheet 17 is reduced, but also the deformation capacity of the bottom auxiliary sheet 7, the tongue depressing auxiliary sheet 10, and the end sheet 17 is increased. The bottom of the tongue depressing auxiliary sheet 10 is provided with an anti-pressure groove 28 on one side close to the connecting sheet 3, which effectively reduces the contact between the tongue depressing auxiliary sheet 10 and the back root of the tongue during use, thereby reducing the occurrence of discomfort such as dry hiccups on the tongue of the patient. The top auxiliary sheet 6, the bottom auxiliary sheet 7, the concave sheet 16, and the end sheet 17 are all made of rubber material, and the outer walls of the top auxiliary sheet 6, the bottom auxiliary sheet 7, the concave sheet 16, and the end sheet 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 of the connecting piece 3, a storage cavity 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 side of the connecting piece 3, a sealing block 25 matching the shape of the sealing groove 26 is provided on the inner wall of the guide piece 5 close to the convex portion 24, and a liquid injection port 27 is provided on the inner wall of the guide piece 5. The first guide portion 19 on the guide piece 5 is used to guide the laryngoscope body 2 to be inserted into the oral cavity and the throat, and before the guide piece 5 is used, a sufficient amount of physiological saline is injected into the storage cavity 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 close to 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 portion 19, the side of the guide piece 5 close to the first guide portion 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 portion 24, the convex portion 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, the stimulation to the throat can be effectively reduced, 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 sheet 5 close to the connecting sheet 3, so that the convex portion 24 can be deformed more easily and quickly in a direction away from the center position of the guide sheet 5 when squeezed. The guide sheet 5 is made of rubber material, and the rubber material has good deformation ability. When not subjected to external force, the guide sheet 5 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 sheet 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, so as to facilitate the storage of the required saline in the storage chamber 21. A second guide portion 22 is provided on one side of the portion 23 close to the sealing block 25, and the edge of one side of the guide piece 5 close to the sealing groove 26 is in an arc shape. 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 to each other more quickly, so that the sealing block 25 can be quickly inserted into the sealing groove 26. The shape of the guide piece 5 is compatible with 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 and lubrication mechanism is better 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 saline into the storage chamber 21 from the injection port 27. The guide plate 5 is in a natural state without being subjected to external forces, and is in a sealed state near the opening 20. The sealing block 25 is stuck in the sealing groove 26, so that the 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, 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, 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 patient's entire oral cavity. 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 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 the patient's throat and preventing the laryngoscope body 2 from deviating and causing strong discomfort caused by scraping the patient's throat. 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 can guide and limit the laryngoscope body 2 while also allowing it to enter 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, the stimulation to the throat can be effectively reduced, thereby reducing the patient's discomfort.
