Abstract
Description
Technical Field
[0001] This application relates to the field of laryngoscope technology, and more particularly to a laryngoscope with a built-in incisor protection device. Background Technology
[0002] A suspension laryngoscopy is a device used for surgery and treatment of pharyngeal lesions. Currently, suspension laryngoscopy is generally made with a hollow metal tube as the endoscope section. When connected to a lighting device, it allows direct observation of the anatomical structures and lesion sites of the pharynx and larynx. With the development of suspension laryngoscopy technology, more and more pharyngeal surgeries centered on suspension laryngoscopy are being performed clinically. Due to its good operability and minimally invasive characteristics, suspension laryngoscopy is often the preferred method for pharyngeal surgeries.
[0003] During clinical procedures, laryngoscopy requires the patient's upper incisors, epiglottis, and vocal cords to be aligned in a straight line to fully expose the lesion and complete the surgery. The incisors are a crucial support point for the laryngoscopy. However, the relatively small contact area between the laryngoscopy and the incisors can lead to excessive force concentration on the incisors, potentially causing surgical complications such as tooth breakage or loss.
[0004] Currently, the main method for protecting the incisors during laryngoscopy is to place soft materials such as gauze on their surfaces to prevent direct contact between the hard metal laryngoscopy tube and the incisors, thus reducing the pressure on them. However, when using gauze, part of it is inside the oral cavity, which can easily obstruct the structures of the pharynx and affect the surgical procedure. Therefore, medical staff usually use a bite block instead of gauze to reduce the area of obstruction. However, since the bite block needs to be used separately from the laryngoscope, it is easily affected and can be displaced when the laryngoscopy tube needs to be moved during insertion, thus reducing the protection of the teeth. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a laryngoscope with a built-in incisor protection device, which aims to solve the problem that gauze cannot effectively protect the incisors in existing laryngoscope surgeries.
[0006] The technical solution adopted by this application to solve the technical problem is as follows: A laryngoscope with a built-in incisor protection device, including a tube and a support rod, wherein the laryngoscope includes a laryngoscope sleeve, which is slidably sleeved on the tube along the sliding direction, and the sliding direction is the same as the axial direction of the tube;
[0007] A dental pad is disposed on the outer surface of the laryngoscope sleeve. One end of the dental pad opposite to the laryngoscope sleeve forms a contact surface for contacting the incisors. The middle part of the contact surface in the sliding direction is recessed toward the laryngoscope sleeve.
[0008] Furthermore, the laryngoscope support also includes: a plurality of sliding parts, the plurality of sliding parts being respectively disposed on the inner surface of the laryngoscope sleeve, the laryngoscope sleeve contacting the endoscope tube through the plurality of sliding parts.
[0009] Furthermore, the sliding part is a groove and / or a protrusion.
[0010] Furthermore, the sliding part is a groove and / or a protrusion provided along the sliding direction.
[0011] Furthermore, the sliding part is a groove, and several sliding parts are spaced apart, with the density of the sliding parts gradually increasing towards the dental pad;
[0012] Alternatively, the sliding part is a protrusion, and several sliding parts are spaced apart, with the density of the sliding parts gradually decreasing towards the dental pad.
[0013] Furthermore, the laryngoscope support also includes an anti-slip portion disposed on the contact surface.
[0014] Furthermore, the laryngoscope support also includes a limiting member, which is disposed on the endoscope tube and used to limit the range of motion of the laryngoscope sleeve.
[0015] Furthermore, the limiting member includes a sliding sleeve, which is disposed on the endoscope tube, and the laryngoscope sleeve is slidably sleeved on the sliding sleeve along the sliding direction;
[0016] A limiting part is provided at one end of the sliding sleeve away from the support rod, and the limiting part is used to contact the laryngoscope sleeve to prevent it from moving further.
[0017] Furthermore, the sliding sleeve is fitted onto the endoscope tube.
[0018] Furthermore, the limiting component also includes a fixing rope, both ends of which are connected to the end of the sliding sleeve facing the support rod. The fixing rope is used to be sleeved on the support rod and detachably connected to it.
[0019] Compared with the prior art, this utility model avoids direct contact between the larynx and the incisors by setting a dental pad. Since the dental pad is slidably set on the larynx through the laryngoscope sleeve, the concave contact surface can be effectively fixed on the incisors, so that the larynx is not easily separated from the incisors by the laryngoscope sleeve when the laryngoscope is inserted, and it will not obstruct the pharyngeal structure. It effectively protects the teeth without affecting the surgical operation. Attached Figure Description

[0029] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0030] This utility model provides, for example Figures 1 to 4 The laryngoscope shown is a built-in incisor 130 protection device, which aims to address the shortcomings of existing laryngoscopes in which gauze cannot effectively protect the incisors 130 during surgery.
[0031] This laryngoscope with built-in incisor 130 protection device mainly includes: laryngoscope cover 200 and dental pad 300.
[0032] The laryngoscope sleeve 200 is slidably mounted on the laryngoscope tube 110 along the sliding direction, and the sliding direction is the same as the axial direction of the laryngoscope tube 110. The dental pad 300 is mounted on the outer surface of the laryngoscope sleeve 200. The end of the dental pad 300 away from the laryngoscope sleeve 200 forms a contact surface 310 for contacting the incisors 130. The middle part of the contact surface 310 in the sliding direction is recessed toward the laryngoscope sleeve 200.
[0033] Specifically, the laryngoscope cover 200 and the bite block 300 can be made of silicone, which can effectively protect teeth. Alternatively, the bite block 300 can be made of silicone, while the laryngoscope cover 200 can be made of other materials, such as plastic.
[0034] In practical use, the endoscope tube 110 is inserted into the patient's mouth, and then the contact surface 310 of the dental pad 300 is placed in contact with the patient's incisors 130. The contact surface 310 can be designed to match the shape of the upper incisors, thereby preventing the incisors 130 from contacting the rigid endoscope tube 110 and reducing the pressure on the incisors 130. Because the concave contact surface 310 of the dental pad 300 can be effectively fixed on the incisors 130, the larynx is less likely to be separated from the incisors 130 due to the influence of the laryngoscope sleeve 200 during endoscope insertion, and it will not obstruct the pharyngeal structure, effectively protecting the teeth without affecting the surgical procedure.
[0035] Specifically, in actual use, the bite pad 300 is placed at the end of the laryngoscope tube 110 facing the support rod 120, and occupies about one-third of the entire tube 110, which can meet the needs of most patients in clinical practice. However, since individual patients have different body shapes, the contact points between the incisors 130 and the tube 110 of the laryngoscope may not be consistent when the same laryngoscope is used on different patients. Therefore, in actual use, the bite pad 300 can slide on the tube 110 along the sliding direction, so that the position of the bite pad 300 can be changed according to different situations.
[0036] Currently, the main method for protecting the incisors during laryngoscopy is to place soft materials such as gauze on their surfaces to prevent direct contact between the hard metal laryngoscopy tube and the incisors, thus reducing the pressure on them. However, when using gauze, part of it is inside the oral cavity, which can easily obstruct the structures of the pharynx and affect the surgical procedure. Therefore, medical staff usually use a bite block instead of gauze to reduce the area of obstruction. However, since the bite block needs to be used separately from the laryngoscope, it is easily affected and can be displaced when the laryngoscopy tube needs to be moved during insertion, thus reducing the protection of the teeth.
[0037] This invention avoids direct contact between the larynx and the incisors by setting a dental pad. Since the dental pad is slidably set on the larynx through the laryngoscope sleeve, the concave contact surface can be effectively fixed on the incisors, so that the larynx is not easily separated from the incisors by the laryngoscope sleeve when the laryngoscope is inserted, and it will not obstruct the pharyngeal structure. It effectively protects the teeth without affecting the surgical operation.
[0038] In some embodiments, such as Figures 1 to 4 As shown, the laryngoscope support also includes several sliding parts 400, which are respectively disposed on the inner surface of the laryngoscope sleeve 200. The laryngoscope sleeve 200 contacts the laryngoscope tube 110 through the several sliding parts 400.
[0039] It should be noted that the presence of several sliding portions 400 that do not cover the inner surface of the laryngoscope sleeve 200 reduces the contact area between the laryngoscope sleeve 200 and the endoscope tube 110. To save costs, both the laryngoscope sleeve 200 and the dental pad 300 could be made of silicone. However, silicone laryngoscope sleeve 200 has higher friction with the endoscope tube 110, which can easily affect its sliding motion on the endoscope tube 110. Therefore, by providing several sliding portions 400 on the inner surface of the laryngoscope sleeve 200 to reduce the contact area between the inner surface of the laryngoscope sleeve 200 and the endoscope tube 110, friction can be effectively reduced, thus facilitating the sliding of the laryngoscope sleeve 200 on the endoscope tube 110.
[0040] In some embodiments, such as Figures 1 to 4 As shown, the sliding part 400 is a groove and / or a protrusion.
[0041] In some embodiments, such as Figures 1 to 4As shown, the sliding part 400 is a groove and / or protrusion provided along the sliding direction.
[0042] Specifically, since materials such as silicone have low hardness, they are prone to deformation during sliding. However, the above structure provides less friction compared to setting the sliding part 400 along the circumference of the laryngoscope sleeve 200.
[0043] In some embodiments, such as Figure 2 As shown, the sliding part 400 is a groove, and several sliding parts 400 are arranged at intervals, and the density of the sliding parts 400 gradually increases towards the dental pad 300;
[0044] Alternatively, the sliding part 400 may be a protrusion, with several sliding parts 400 spaced apart, and the density of the sliding parts 400 gradually decreasing toward the dental pad 300.
[0045] Specifically, when the patient's incisors 130 contact the dental pad 300, a force can be applied to the dental pad 300 in the direction of the laryngoscope sleeve 200. Through this structure, the laryngoscope sleeve 200 is structurally weaker at the end facing the dental pad 300, making it more prone to indentation under the force of the dental pad 300. This increases the contact area with the endoscope tube 110, thereby increasing the friction between the laryngoscope sleeve 200 and the endoscope tube 110. When medical personnel need to push the endoscope tube 110 during insertion or other situations, the endoscope tube 110 can be tilted slightly upwards to reduce the force between the dental pad 300 and the patient's teeth. Conversely, when there is no need to push the endoscope tube 110, it can be placed naturally or pressed down. This increases the friction between the laryngoscope sleeve 200 and the endoscope tube 110, improving the stability of the endoscope tube 110 during surgery.
[0046] In some embodiments, such as Figures 1 to 4 As shown, the laryngoscope support also includes an anti-slip part 311, which is disposed on the contact surface 310. This increases the friction between the contact surface 310 and the patient's teeth, effectively preventing the dental aligner from dislodging from its preset position.
[0047] In some embodiments, such as Figure 4 As shown, the laryngoscope support also includes a limiting member 500, which is disposed on the endoscope tube 110 and used to limit the range of motion of the laryngoscope sleeve 200. This prevents the laryngoscope sleeve 200 from detaching from the endoscope tube 110 and remaining in the patient's mouth when the endoscope is withdrawn after surgery.
[0048] In some embodiments, such as Figure 4 As shown, the limiting member 500 includes: a sliding sleeve 510, which is disposed on the endoscope tube 110, and the laryngoscope sleeve 200 is disposed on the sliding sleeve 510 along the sliding direction;
[0049] The limiting part 520 is provided at one end of the sliding sleeve 510 away from the support rod 120. The limiting part 520 is used to contact the laryngoscope sleeve 200 to prevent it from moving further.
[0050] Specifically, the limiting part 520 can be a ring structure and sleeved on the laryngoscope tube 110. It is connected to the sliding sleeve 510, and its outer diameter is larger than the inner diameter of the laryngoscope sleeve 200.
[0051] In some embodiments, such as Figure 4 As shown, the sliding sleeve 510 is fitted onto the lens tube 110. This provides greater stability.
[0052] In some embodiments, such as Figure 4 As shown, the limiting member 500 also includes a fixing rope 530, both ends of which are connected to the end of the sliding sleeve 510 facing the support rod 120. The fixing rope 530 is used to be sleeved on the support rod 120 and detachably connected to it.
[0053] Specifically, such as Figure 4 As shown, the fixing rope 530 can prevent the sliding sleeve 510 from separating from the endoscope tube 110 and losing its function of restricting the range of motion of the laryngoscope sleeve 200, thereby preventing the laryngoscope sleeve 200 from leaving in the patient's mouth when the endoscope tube 110 is withdrawn after surgery.
[0054] In summary, a laryngoscope with a built-in incisor protection device is provided, comprising a laryngoscope sleeve and a dental pad. The laryngoscope sleeve is slidably fitted onto the endoscope tube along a sliding direction, which is the same as the axial direction of the endoscope tube. The dental pad is disposed on the outer surface of the laryngoscope sleeve, with one end of the dental pad facing away from the laryngoscope sleeve forming a contact surface for contacting the incisors. The middle of the contact surface is recessed towards the laryngoscope sleeve in the sliding direction. This invention avoids direct contact between the larynx and the incisors by using a dental pad. Since the dental pad is slidably mounted on the larynx through the laryngoscope sleeve, the recessed contact surface can effectively fix it to the incisors, making it less likely for the larynx to separate from the incisors due to the influence of the laryngoscope sleeve during insertion of the endoscope, and it does not obstruct the pharyngeal structure, effectively protecting the teeth without affecting the surgical procedure.
[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
