Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intubation anesthesia, in particular to an intubation anesthesia auxiliary device. BACKGROUND

[0002] Intubation anesthesia refers to a method of implementing anesthesia by adopting tracheal intubation in order to maintain the function of the respiratory tract of a patient and ensure that the patient does not have respiratory tract obstruction and respiratory depression during general anesthesia. In the process of tracheal intubation, a laryngoscope is used to open the mouth of the patient first, then a tracheal tube is inserted into the trachea of the patient, and finally the patient is supplied with oxygen by means of the tracheal tube.

[0003] In actual operation, after the operator opens the mouth of the patient by means of the laryngoscope, the operator needs to hold the laryngoscope with one hand and insert the tracheal tube with the other hand. After the tracheal tube is inserted, the operator holds the tracheal tube and the laryngoscope with one hand and arranges a mouth pad with the other hand. After the mouth pad is arranged, the laryngoscope is removed, and then the operator holds the tracheal tube and the mouth pad with one hand and completes the following operations with the other hand: inflating the tracheal tube, auscultating the lungs and chest of the patient, and binding and fixing the tracheal tube and the mouth pad. The above process requires high proficiency of the operator, and since most of the operations can only be completed with one hand, mistakes are likely to occur. Long-time single-handed operation is not only laborious but also affects the stability of the operator's hand, thereby affecting the comfort of the patient and the efficiency of the tracheal tube. Therefore, in order to improve the efficiency of the tracheal tube and the convenience of the operator, the present application provides an intubation anesthesia auxiliary device to meet the needs. SUMMARY

[0004] The technical problem to be solved by the present application is to provide an intubation anesthesia auxiliary device which can assist the operator in holding and fixing the laryngoscope and the tracheal tube, thereby eliminating the need for the operator to hold the laryngoscope and the tracheal tube with his hands all the time, improving the convenience of the operator when performing other operations, and assisting the operator in opening the mouth of the patient. Moreover, the size of the opened mouth of the patient can be quickly adjusted, which not only improves the surgical field of the operator but also improves the success rate of the tracheal tube placement. In addition, the positioning assembly can automatically achieve the fixing effect of the tracheal tube, thereby further reducing the difficulty of the surgical operation and improving the efficiency of the operator. The above settings can solve the problems of low efficiency and high operation difficulty in the current tracheal tube operation process.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0008] Optionally, one end of the gas bag close to the neck positioning plate is fixedly connected with a neck pad, the two sides of the gas bag are respectively provided with an air inlet and an air outlet, the neck pad is a circular arc-shaped profile protruding upward, and the gas bag and the neck pad are integrally manufactured in a communication mode.

[0009] Optionally, the shoulder positioning plate is a circular arc-shaped profile, a first bending part is installed at the middle position of the neck positioning plate, and a second bending part is installed at the top of the neck positioning plate.

[0010] Optionally, the first bending part has an inwardly recessed profile, the second bending part has an outwardly protruding profile, the second bending part is sequentially provided with a straight sliding groove and a limiting groove from top to bottom, and a plurality of protrusions are arranged at the top of the limiting groove.

[0011] Optionally, one end of the first pull rod and the second pull rod close to the neck positioning plate is fixedly connected with an S-shaped bending rod, the S-shaped bending rod has an "S" shape, the S-shaped bending rod is provided with a weakened groove, and the S-shaped bending rod is thinned by the weakened groove.

[0012] Optionally, the other end of the first pull rod and the second pull rod is fixedly connected with a chuck, the middle position of the first supporting rod and the second supporting rod is provided with a clamping groove, the first pull rod and the first supporting rod and the second pull rod and the second supporting rod are fixed through the chuck, and the size of the chuck is consistent with the size of the clamping groove.

[0013] Optionally, the first supporting rod is fixedly connected with a first arc-shaped plate, the second supporting rod is fixedly connected with a second arc-shaped plate, the first supporting rod and the first arc-shaped plate and the second supporting rod and the second arc-shaped plate are fixed through elastic bending rods, the first supporting rod and the second supporting rod have a "C" shape, and the two ends of the first supporting rod and the second supporting rod are fixedly connected with inwardly bent bending rods.

[0014] Optionally, both ends of the first arc-shaped plate are fixedly connected to an insertion part, and both ends of the second arc-shaped plate are fixedly connected to an outward-turned part. The outward-turned part has an outward-turned profile, and a slot that matches the size of the insertion part is provided on the outward-turned part.

[0015] Optionally, both the first support rod and the second support rod are fixedly connected with C-shaped bend plates, wherein the C-shaped bend plates have a "C" shaped profile, and the elastic bend rod has a curved elastic structure.

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

[0017] In the above-mentioned solution, by setting a positioning component, the operator can be assisted in holding and fixing the laryngoscope and endotracheal tube, thus eliminating the need for the operator to constantly hold the laryngoscope and endotracheal tube by hand, improving the convenience of the operator when performing other operations. The positioning component can also help the operator open the patient's mouth, and the size of the opening can be quickly adjusted. This not only improves the operator's surgical field of vision but also increases the success rate of endotracheal tube insertion. Currently, after the endotracheal tube is inserted, a bite block is needed to protect it. In this application, the positioning component not only eliminates the need for a bite block but also automatically achieves the effect of fixing the endotracheal tube, thereby further reducing the difficulty of the surgical operation and improving the efficiency of the operator.

[0018] By setting up an S-shaped curved rod, a straight sliding groove, and a limiting groove, the S-shaped curved rod is inserted from top to bottom into the straight sliding groove and the limiting groove on the neck positioning plate. This staggered interlocking structure allows the S-shaped curved rod to be limited by the straight sliding groove and the limiting groove, preventing misalignment and detachment of the S-shaped curved rod during sliding on the neck positioning plate. The cooperation of the S-shaped curved rod, the straight sliding groove, and the limiting groove allows the first and second pull rods to be assembled with the neck positioning plate, and both the first and second pull rods can slide on the neck positioning plate. The sliding process is stable and easy to operate.

[0019] By setting up a first support rod and a second support rod, the operator can use these rods to open the patient's mouth. Simultaneously, the S-shaped curved rod, in conjunction with the neck positioning plate, can adjust the distance between the first and second support rods, thereby changing the size of the opened mouth. This opening method not only does not affect the internal tissues of the patient's mouth but also does not obstruct the patient's view inside the mouth, thus ensuring the efficiency of the operator during endotracheal intubation. Because the first and second support rods are detachable and reassembleable, the operator can select the appropriate size based on the patient's individual needs to accommodate more patients. The angles of the first and second support rods can be manually adjusted to better fit the patient's oral cavity contour, improving patient comfort and enhancing the support and opening effect on the patient's mouth.

[0020] By setting up a first and second arc-shaped plate, the endotracheal tube can be fixed in place after it is inserted into the patient's body, eliminating the need for manual manipulation. Furthermore, the first and second support rods can open the patient's mouth, preventing the patient from biting down on the tube during fixation and eliminating the need for a bite block, thus saving medical costs. The flexible bending rods also buffer and absorb the shaking and pulling that occurs when the endotracheal tube is connected to other tubes, preventing the connection operation from affecting the support effect of the first and second support rods on the patient's mouth and improving patient safety.

[0021] By setting a C-shaped bend, not only can the laryngoscope be guided, but the operator can also use the C-shaped bend as a fulcrum to change the opening angle of the laryngoscope to the patient's mouth, thereby reducing the force required by the operator's hands, reducing the difficulty of operation, and improving surgical efficiency.

[0043] like Figures 1 to 5As shown, an embodiment of the present invention provides an intubation anesthesia assistance device, including a base plate 1, a limiting plate 102 fixedly connected to the top of the base plate 1, an airbag 2 inserted into the limiting plate 102, a neck positioning plate 3 and a shoulder positioning plate 101 symmetrically installed on the top of the base plate 1, a neck pad 201 fixedly connected to one end of the airbag 2 near the neck positioning plate, an air inlet and an air outlet respectively provided on both sides of the airbag 2, the neck pad 201 having an upwardly convex arc-shaped contour, the airbag 2 and the neck pad 201 being an integrally manufactured structure interconnected, the shoulder positioning plate 101 having an arc-shaped contour, a first bend 301 installed at the middle position of the neck positioning plate 3, a second bend 302 installed at the top of the neck positioning plate 3, the first bend 301 having an inwardly concave contour, and the second bend 302 having an outwardly convex contour; a positioning component, the positioning component being used to assist the operator in placing the endotracheal tube 12 and laryngoscope 11, the positioning component being connected to the neck positioning plate 3.

[0044] The intubation anesthesia assistance device provided in this application is mainly applicable to patients under general anesthesia. It helps maintain the patient's airway function with the help of endotracheal intubation 12. Compared with the prior art, the assistance device provided in this application can effectively improve the convenience of the operator when performing endotracheal intubation 12 on the patient, reduce the burden of the operator's hand operation, improve the efficiency of endotracheal intubation 12 operation, and provide the patient with a safer and more comfortable surgical environment.

[0045] Specifically, by installing an airbag 2, a shoulder positioning plate 101, and a neck positioning plate 3 on the base plate 1, the patient's position can be limited. During actual operation, the base plate 1 is placed on the operating table, with the patient's upper body pressing against the top of the base plate 1. The patient's own pressure helps to fix the base plate 1. When the patient lies flat, the tops of the patient's shoulders rest against the inner wall of the shoulder positioning plate 101. Because the shoulder positioning plate 101 has a rounded contour, this structural design improves the fit between the shoulder positioning plate 101 and the patient's shoulder contour, thereby... The shoulder positioning plate 101 improves the positioning effect of the shoulder on the patient and the comfort of the patient's shoulder. When the patient is lying flat, the patient's neck is located in the middle of the two neck positioning plates 3, the back of the patient's neck is against the top of the neck pad 201, and the patient's head is against the top of the airbag 2. The airbag 2 is set in the limiting plate 102, and the height of the limiting plate 102 is greater than the height of the airbag 2, so the airbag 2 can be limited to prevent the airbag 2 from shifting position after inflation. Because the neck positioning plate 3 is provided with a first bending part 301 and a second bending part 30 2. The first bend 301 has an inwardly concave contour, and the second bend 302 has an outwardly convex contour. This curvature is designed to improve the fit between the neck positioning plate 3 and the patient's neck contour. The inwardly concave contour of the first bend 301 allows the neck positioning plate 3 to wrap and position the patient's neck, while the outwardly convex contour of the second bend 302 facilitates neck support when the patient lies down in the middle of the neck positioning plate 3. The guide not only improves the efficiency of patient positioning but also prevents the patient's neck from being scratched by the neck positioning plate 3. After the patient is in position, the operator inflates the air bag 2 with air. As the air bag 2 inflates, the neck pad 201 will also expand. Since the neck pad 201 has an upward convex arc shape, it can raise the patient's neck when it is inflated. This design ensures that the patient's mouth, pharynx, and larynx are in a straight line after the neck is raised, making it easier for the operator to insert the endotracheal tube 12 into the patient's trachea.

[0046] With the above-mentioned structure, the patient's position can be positioned using the shoulder positioning plate 101 and the neck positioning plate 3 after lying on the hospital bed. This configuration improves the stability of the patient's body. When the air bag 2 is inflated, the neck pad 201 will raise the patient's neck. At this time, under the positioning effect of the shoulder positioning plate 101 and the neck positioning plate 3, the patient's mouth, pharynx, and larynx are in a straight line, which makes it easier for the operator to insert the endotracheal tube 12 into the patient's body, improves the success rate and convenience of the endotracheal tube 12 operation, and reduces damage to the patient's pharynx and larynx during the intubation process.

[0047] The auxiliary device provided in this application also includes a positioning component, which assists the operator in holding and fixing the laryngoscope 11 and endotracheal tube 12, thus eliminating the need for the operator to constantly hold the laryngoscope 11 and endotracheal tube 12 by hand, improving the convenience of the operator when performing other operations. In addition, the positioning component can assist the operator in opening the patient's mouth, and the size of the opening can be quickly adjusted. This not only improves the operator's surgical field of vision but also increases the success rate of endotracheal tube 12 insertion. Currently, after the endotracheal tube 12 is inserted, it needs to be protected with a bite block. In this application, the positioning component not only eliminates the need for a bite block but also automatically achieves the fixation effect of the endotracheal tube 12, thereby further reducing the difficulty of the surgical operation and improving the efficiency of the operator.

[0048] As one implementation method in this embodiment, such as Figures 1 to 5 As shown, the positioning assembly includes a first pull rod 4 and a second pull rod 5 inserted into the neck positioning plate 3. An S-shaped bent rod 6 is fixedly connected to one end of both the first pull rod 4 and the second pull rod 5 near the neck positioning plate 3. The S-shaped bent rod 6 has an "S" shape outline and a weakening groove 601 is provided on it. The weakening groove 601 thins the S-shaped bent rod 6. The second bending portion 302 has a straight sliding groove 303 and a limiting groove 304 sequentially formed from top to bottom. The top of the limiting groove 304 is provided with... Multiple protrusions are provided. The first pull rod 4 and the second pull rod 5 are respectively installed on the neck positioning plate 3 on both sides of the patient's neck. The connection method between the first pull rod 4 and the second pull rod 5 and the neck positioning plate 3 is the same. Here, we take the first pull rod 4 as an example. An S-shaped curved rod 6 is installed at the end of the first pull rod 4 near the neck positioning plate 3. The S-shaped curved rod 6 not only has an "S" shape in outline, but also passes through the straight sliding groove 303 and the limiting groove 304 on the neck positioning plate 3 from top to bottom (e.g., Figure 2 and Figure 4As shown), this staggered interlocking structure allows the S-shaped curved rod 6 to be limited by the straight sliding groove 303 and the limiting groove 304, preventing misalignment and detachment of the S-shaped curved rod 6 during its sliding on the neck positioning plate 3. Because the S-shaped curved rod 6 has a weakening groove 601, and the weakening groove 601 thins the S-shaped curved rod 6, it is easily deformed at the position of the weakening groove 601 under external force. The limiting groove 304 consists of two parts: the top has multiple protrusions, the spacing between which matches the size of the S-shaped curved rod 6; the bottom of the limiting groove 304 is a flat groove. In the initial state, the end of the S-shaped curved rod 6 is engaged with the top of the limiting groove 304 and limited by the protrusions at the top of the limiting groove 304. When the operator needs to slide the S-shaped curved rod 6, they first press down on the end of the S-shaped curved rod 6, allowing... The S-shaped bend 6 deforms from the position of the weakening groove 601, causing the end of the S-shaped bend 6 to move from the top of the limiting groove 304 to the bottom of the limiting groove 304. At this time, the protrusion at the top of the limiting groove 304 can no longer block the S-shaped bend 6, and the operator can slide to adjust the position of the S-shaped bend 6. When it is necessary to fix the S-shaped bend 6 again, stop pressing the S-shaped bend 6. After the pressure is released, the S-shaped bend 6 will return to the top of the limiting groove 304 under its own elastic force and be fixed again by the protrusion at the top of the limiting groove 304. Through the above structure, under the structural cooperation of the S-shaped bend 6, the straight sliding groove 303 and the limiting groove 304, the first pull rod 4 and the second pull rod 5 are assembled with the neck positioning plate 3, and both the first pull rod 4 and the second pull rod 5 can slide on the neck positioning plate 3. The stability is good and the operation is convenient during the sliding process.

[0049] In this embodiment, as Figures 1 to 9As shown, one end of the first pull rod 4 is engaged with the first support rod 401, and one end of the second pull rod 5 is engaged with the second support rod 501. The other ends of both the first pull rod 4 and the second pull rod 5 are fixedly connected to clamps 9. A clamping groove 10 is provided at the middle position of both the first support rod 401 and the second support rod 501. The first pull rod 4 and the first support rod 401, and the second pull rod 5 and the second support rod 501 are both fixed by clamps 9. The size of the clamps 9 matches the size of the clamping grooves 10. Clamps 9 are installed on both the first pull rod 4 and the second pull rod 5. The clamps 9 are used to connect and fix the first support rod 401 and the second support rod 501. Because the size of the clamps 9 matches the size of the clamping grooves 10, and the clamps 9 have a "C" shaped outline, the operator... The operator can use the "C"-shaped contour of the chuck 9 to press and clamp the first support rod 401 and the second support rod 501 into the chuck 9. After the first support rod 401 and the second support rod 501 are clamped and fixed together with the chuck 9, the first support rod 401 and the second support rod 501 cannot move or rotate under the action of friction and clamping force. When the operator forcefully pries the first support rod 401 and the second support rod 501, they can rotate on the chuck 9. This installation method not only allows the first support rod 401 and the second support rod 501 to be removed from the first pull rod 4 and the second pull rod 5, but also allows the relative angle between the first support rod 401 and the second support rod 501 and the first pull rod 4 and the second pull rod 5 to be changed by hand.

[0050] In this embodiment, as Figures 1 to 12As shown, a first arc-shaped plate 402 is fixedly connected to the first support rod 401, and a second arc-shaped plate 402 is fixedly connected to the second support rod 501. The first support rod 401 and the first arc-shaped plate 402 are fixedly connected to each other, and the second support rod 501 and the second arc-shaped plate 502 are fixedly connected by elastic bent rods 7. Both the first support rod 401 and the second support rod 501 have a "C"-shaped profile, and both ends of the first support rod 401 and the second support rod 501 are fixedly connected to inwardly bent rods. Both ends of the first arc-shaped plate 402 are fixedly connected to insertion portions 403. The second arc-shaped plate 402... Both ends of the shaped plate 502 are fixedly connected to outward-flaring portions 503, which have an outward-flaring profile. The outward-flaring portions 503 have slots 504 that match the size of the insertion portion 403. C-shaped bent plates 8 are fixedly connected to both the first support rod 401 and the second support rod 501. The C-shaped bent plates 8 have a "C"-shaped profile. The elastic bent rod 7 has a curved elastic structure. In actual operation, the operator needs to use the first support rod 401 and the second support rod 501 to lift and open the patient's mouth. Specifically, the operator makes the first support rod 401 contact the patient's lower teeth. On the inner wall of the patient's upper teeth, the second support rod 501 is brought into contact with the inner wall of the patient's upper teeth. Then, the positions of the first pull rod 4 and the second pull rod 5 on the cervical positioning plate 3 are manually adjusted to increase the distance between the first pull rod 4 and the second pull rod 5, thereby opening the patient's oral cavity. Since both the first support rod 401 and the second support rod 501 have a "C"-shaped profile, when the first support rod 401 and the second support rod 501 are placed on the inner wall of the patient's teeth, their "C"-shaped profile structure allows the two ends of the first support rod 401 and the second support rod 501 to extend from the inner wall of the patient's teeth. Extending to the vicinity of the gum line, the first support rod 401 and the second support rod 501 have a larger contact area with the patient's teeth, improving the firmness and stability of the fit between the first support rod 401 and the second support rod 501 and the patient's teeth, and preventing slippage during the support process. Since both ends of the first support rod 401 and the second support rod 501 are fixedly connected with inwardly bent rods, the inwardly bent rods make the end structure of the first support rod 401 and the second support rod 501 more rounded, thereby preventing the first support rod 401 and the second support rod 501 from scratching the patient's oral cavity.

[0051] Furthermore, the operator can use the first support rod 401 and the second support rod 501 to open the patient's mouth. Simultaneously, the operator can adjust the distance between the first support rod 401 and the second support rod 501 using the S-shaped curved rod 6 and the neck positioning plate 3, thereby changing the size of the opened mouth. This opening method not only does not affect the internal tissues of the patient's mouth but also does not obstruct the patient's view inside the mouth, thus ensuring the efficiency of the operator's endotracheal intubation 12 procedure. Additionally, since the first support rod 401 and the second support rod 501 are detachable and assembleable, the operator can select the size of the first and second support rods 501 according to the patient's individual needs to accommodate more patients. Moreover, the angles of the first support rod 401 and the second support rod 501 can be manually adjusted to better fit the patient's oral cavity contour, improving patient comfort and enhancing the support and opening effect on the patient's mouth.

[0052] A first arc-shaped plate 402 and a second arc-shaped plate 502 are respectively installed on the first support rod 401 and the second support rod 501. The first arc-shaped plate 402 and the second arc-shaped plate 502 can be snapped together. Since the size of the two when they are snapped together matches the size of the endotracheal tube 12, the endotracheal tube 12 can be fixed when they are snapped together. Specifically, the operator can shorten the distance between the first arc-shaped plate 402 and the second arc-shaped plate 502 so that the insertion part 403 is inserted into the slot 504. Since the size of the insertion part 403 and the slot 504 match, they can limit each other when they are inserted together. In addition, the second arc-shaped plate 502 is also provided with an outward-curving part 503. Since the outward-curving part 503 has an outward-curving part 503, it can... The outward-curved contour of the insert 403 allows for auxiliary guidance during insertion into the slot 504, ensuring that the insert 403 does not shift or become misaligned, thus improving the convenience of the surgical procedure. After the operator inserts the endotracheal tube 12 into the patient's body, the first arc plate 402 and the second arc plate 502 can be used to fix the endotracheal tube 12, eliminating the need for the operator to manually hold the endotracheal tube 12. Furthermore, the first support rod 401 and the second support rod 501 can open the patient's mouth, preventing the patient from biting the endotracheal tube 12 when it is being held and fixed, thus eliminating the need for the currently used dental pad and saving medical costs.

[0053] Furthermore, since the first support rod 401 and the first arc-shaped plate 402, and the second support rod 501 and the second arc-shaped plate 502 are both fixed by elastic bending rods 7, and the elastic bending rods 7 are curved elastic structures, this arrangement allows the first support rod 401 and the first arc-shaped plate 402, as well as the second support rod 501 and the second arc-shaped plate 502, to undergo certain elastic deformation with the help of the elastic bending rods 7. After the endotracheal tube 12 is fixed, the operator needs to connect other tubes to the endotracheal tube 12. When connecting other tubes, the endotracheal tube 12 will inevitably shake and be pulled. This will not only affect the stability of the first support rod 401 and the second support rod 501 in supporting and opening the patient's mouth, but also cause certain frictional damage to the patient's trachea. By setting the elastic bending rods 7, the shaking and pulling of the endotracheal tube 12 can be buffered and absorbed, preventing the support effect of the first support rod 401 and the second support rod 501 on the patient's mouth from being affected by the tube connection operation, while improving the patient's safety.

[0054] Furthermore, C-shaped bends 8 are installed on both the first support rod 401 and the second support rod 501. Since the size of the C-shaped bends 8 matches that of the laryngoscope 11, the operator can use the C-shaped bends 8 to assist in positioning the laryngoscope 11. In actual operation, the operator needs to rotate the angle of the laryngoscope 11 to open the patient's glottis. When the operator holds the laryngoscope 11, the laryngoscope 11 should not come into contact with the patient's teeth to avoid the laryngoscope 11 grinding the patient's teeth. In this application, since the C-shaped bends 8 are set on the first support rod 401 and the second support rod 501, this position setting can not only assist in guiding the laryngoscope 11, but also allow the operator to change the opening angle of the laryngoscope 11 against the patient's oral cavity by using the C-shaped bends 8 as a fulcrum, thereby reducing the force required by the operator's hands, reducing the difficulty of operation, and improving surgical efficiency.

[0055] The working principle of the technical solution provided by this invention is as follows:

[0056] In use, the anesthetized patient lies on the base plate 1, with the tops of the patient's shoulders resting against the inner wall of the shoulder positioning plate 101. Because the shoulder positioning plate 101 has a rounded contour, this structure improves the fit between the shoulder positioning plate 101 and the patient's shoulder contour, thereby improving the positioning effect of the shoulder positioning plate 101 on the patient's shoulders and the patient's shoulder comfort. The patient's neck is positioned between the two neck positioning plates 3, with the back of the patient's neck resting against the top of the neck pad 201, and the patient's head resting against the top of the airbag 2. The neck positioning plate 3 has a first bend 301 and a second bend 302, and the first bend... The first bend 301 has an inwardly concave contour, and the second bend 302 has an outwardly convex contour. This curvature is designed to improve the fit between the neck positioning plate 3 and the patient's neck contour. The inwardly concave contour of the first bend 301 is designed to allow the neck positioning plate 3 to wrap and position the patient's neck. The outwardly convex contour of the second bend 302 is designed to facilitate the patient's neck to be guided when lying down in the middle of the neck positioning plate 3 from top to bottom. This not only improves the efficiency of patient positioning but also prevents the patient's neck from being scratched by the neck positioning plate 3.

[0057] After the patient lies down, the operator inflates the air bag 2 with air. As the air bag 2 inflates, the neck pad 201 also expands. Since the neck pad 201 has an upward-convex arc shape, it can raise the patient's neck when it is inflated. This design ensures that the patient's mouth, pharynx, and larynx are in a straight line after the neck is raised, making it easier for the operator to insert the endotracheal tube 12 into the patient's trachea.

[0058] The operator manually adjusts the relative positions of the first pull rod 4 and the second pull rod 5 on the cervical positioning plate 3, so that the top of the first pull rod 4 is positioned at the patient's lower teeth and the top of the second pull rod 5 is positioned at the patient's upper teeth. First, press down on the end of the S-shaped curved rod 6, causing it to deform from the weakening groove 601 and move its end from the top of the limiting groove 304 to the bottom of the limiting groove 304. At this point, the protrusion at the top of the limiting groove 304 can no longer block the S-shaped curved rod 6, allowing the operator to slide it. The position of the S-shaped bend 6 has been adjusted. When it is necessary to re-fix the S-shaped bend 6, stop pressing on the S-shaped bend 6. After the pressure is released, the S-shaped bend 6 will return to the top of the limiting groove 304 under its own elastic force and be fixed again by the protrusion at the top of the limiting groove 304. After the positions of the first pull rod 4 and the second pull rod 5 are adjusted, the operator makes the first support rod 401 abut against the inner wall of the patient's lower teeth and the second support rod 501 abut against the inner wall of the patient's upper teeth, and then manually adjusts the first pull rod 4 and the second support rod 501. The position of the second pull rod 5 on the neck positioning plate 3 increases the distance between the first pull rod 4 and the second pull rod 5, thereby opening the patient's oral cavity. Since both the first support rod 401 and the second support rod 501 have a "C"-shaped profile, when the first support rod 401 and the second support rod 501 are placed on the inner wall of the patient's teeth, their "C"-shaped profile structure allows both ends of the first support rod 401 and the second support rod 501 to extend from the inner wall of the patient's teeth to near the gum line. This increases the contact area between the first support rod 401 and the second support rod 501 and the patient's teeth, improving the firmness and stability of the fit between the first support rod 401 and the second support rod 501 and the patient's teeth, and preventing slippage during the support process. Since both ends of the first support rod 401 and the second support rod 501 are fixedly connected with inwardly bent rods, the inwardly bent rods make the end structure of the first support rod 401 and the second support rod 501 more rounded, thereby preventing the first support rod 401 and the second support rod 501 from scratching the patient's oral cavity.

[0059] After the patient's mouth is opened, the operator uses laryngoscope 11 to open the patient's glottis. Since the C-shaped curved plate 8 matches the size of the laryngoscope 11, the operator can use the C-shaped curved plate 8 to assist in positioning the laryngoscope 11. During the actual operation, the operator uses the C-shaped curved plate 8 as a fulcrum to change the opening angle of the laryngoscope 11 relative to the patient's mouth, thereby reducing the force required by the operator's hands, lowering the difficulty of the operation, and improving surgical efficiency. After the patient's glottis is opened, the endotracheal tube 12 is inserted into the patient's body. After the endotracheal tube 12 is inserted, the laryngoscope 11 is removed. Then, the operator shortens the distance between the first arc plate 402 and the second arc plate 502, allowing the insertion part 403 to be inserted into the slot 5. Within 04, since the dimensions of the insertion part 403 and the slot 504 match, they can mutually limit each other after being inserted together. Since the dimensions of the first arc plate 402 and the second arc plate 502 match those of the endotracheal tube 12 after being snapped together, the endotracheal tube 12 can be fixed by means of the first arc plate 402 and the second arc plate 502, so that the operator does not need to manually hold the endotracheal tube 12. Moreover, the first support rod 401 and the second support rod 501 can open the patient's mouth, so when holding and fixing the endotracheal tube 12, it will not cause the patient's teeth to bite the endotracheal tube 12, thus eliminating the need for the currently used bite block and saving medical costs.
