Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a self-administered anesthesia intubation device for laryngoscope in otolaryngology. Background Technology

[0002] The ENT laryngoscope-guided self-administered anesthesia intubation device is a medical device specifically designed for use in ENT clinical settings to guide the administration of anesthesia to patients requiring endotracheal intubation under the assistance of a laryngoscope.

[0003] In existing ENT laryngoscope-guided anesthesia intubation devices, the guide tube inserted into the oral cavity provides guidance and limitation for the anesthetic administration tube to complete the intubation operation under laryngoscopy. When a cricoarytenoid joint dislocation is found after intubation and emergency reduction is required, the intubation device must be completely withdrawn from the patient's oral cavity before a separate cricoarytenoid joint reduction forceps can be reinserted. The repeated insertion and removal of instruments requires re-exposing the field of vision and locating the target point, which reduces the efficiency of cricoarytenoid joint reduction. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a self-administered anesthesia intubation device under laryngoscopy in otolaryngology, which improves the operational efficiency of cricoarytenoid joint reduction.

[0014] Furthermore, the connecting part and the movable part are rotatably connected by a universal hinge structure, so that the movable part can rotate relative to the connecting part at multiple angles.

[0015] Furthermore, the guide portion has a reset groove on the periphery of the movable slot opening, the reset groove extends along the length direction of the movable slot, and the reset groove is connected to the movable slot; the movable portion slides with the connecting portion, inserting into the reset groove or disengaging from the reset groove.

[0016] Furthermore, of the reset groove and the movable part, one is provided with a limiting magnetic attraction part, and the other is provided with a limiting magnetic attraction engagement part. The limiting magnetic attraction part and the limiting magnetic attraction engagement part are used to attract each other during the insertion process of the movable part and the reset groove.

[0017] The guide portion is provided with at least two positioning magnetic suction portions, which are arranged at intervals on opposite sides of the reset groove along the length direction of the guide portion; the reset execution structure is provided with at least two positioning magnetic suction engagement portions, and each positioning magnetic suction engagement portion is attracted and positioned with the corresponding positioning magnetic suction portion.

[0018] Furthermore, the movable slot is connected to the guide channel; the end of the connecting part away from the movable part is provided with an anti-displacement block, the anti-displacement block protrudes into the guide channel, and the anti-displacement block is used to abut against the outer wall of the anesthesia administration tube when the anesthesia administration tube passes through the guide channel.

[0019] Furthermore, the reset execution structure includes a support arm and a movable arm; the guide rail and each of the positioning magnetic attraction parts are located on the support arm;

[0020] The support arm and the movable arm are rotatably connected by a hinge shaft, so that the movable arm can move relative to the support arm;

[0021] The supporting arm and the movable arm together form a clamping structure at the end that extends into the patient's mouth, and the clamping structure is used to clamp the cricoarytenoid joint.

[0022] Furthermore, both the support arm and the movable arm are equipped with operating handles, each operating handle having a mounting part, an operating part, and a rotating shaft; the two mounting parts are detachably mounted to the end of the support arm away from the clamping structure and the end of the movable arm away from the clamping structure, respectively; the operating part is used for medical personnel to grip and apply force.

The repositioning actuator is installed on the guide section and extends into the patient's oral cavity synchronously with the guide section. The repositioning actuator and the guide section together form a guide channel for guiding the anesthetic administration tube into the patient's oral cavity. This achieves simultaneous insertion of the anesthetic administration and the repositioning actuator, eliminating the need for medical staff to separately insert the cricoarytenoid joint repositioning device into the patient's oral cavity after intubation anesthesia. This reduces the number of device insertions, avoids irritation to the patient's oral tissues during multiple device insertions, and saves preparation time.

The repositioning execution structure can be moved flexibly in the patient's oral cavity by the detachable structure, so that the repositioning operation can be carried out quickly. This avoids problems such as visual field obstruction and re-exposure caused by repeated instrument entry and exit in the patient's oral cavity. At the same time, the guide part always remains in its original position in the patient's oral cavity, eliminating the need for medical staff to reposition the operation target point. This saves the tedious step of target point repositioning, shortens the overall time of the repositioning operation, reduces the operation difficulty for medical staff, and reduces operation errors caused by repeated positioning and instrument adjustment. This improves the operation efficiency of cricoarytenoid joint repositioning, reduces patient discomfort during the operation, and enhances the safety and convenience of the operation.

[0037] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] See Figures 1-4 The specific implementation of a preferred embodiment of the present invention is as follows: A self-administered anesthesia intubation device under laryngoscopy in otolaryngology includes: a laryngoscope body 1, a repositioning execution structure 2, and a separable structure 4.

[0041] The laryngoscope body 1 has a guide portion 11, which is used to be inserted into the patient's oral cavity;

[0042] The reset execution structure 2 is installed on the guide part 11 and extends into the patient's oral cavity simultaneously with the guide part 11; the reset execution structure 2 and the guide part 11 together form a guide channel 3, which is used to guide the anesthetic drug delivery tube into the patient's oral cavity;

[0043] The connecting part 41 of the separable structure 4 is assembled to the guide part 11, and the movable part 42 of the separable structure 4 is assembled to the reset execution structure 2, so that the reset execution structure 2 moves relative to the guide part 11 in the patient's oral cavity to perform a cricoarytenoid joint reset operation; the guide channel 3 is released from enclosure as the reset execution structure 2 moves relative to the guide part 11.

[0044] In use, medical staff hold the laryngoscope body 1 and slowly insert the guide part 11, which is equipped with the repositioning actuator 2, into the patient's oral cavity until the guide part 11 reaches the target position required for intubation. During this process, the repositioning actuator 2 is inserted into the patient's oral cavity simultaneously with the guide part 11, without the need for separate additional repositioning instruments. Subsequently, the medical staff slowly inserts the anesthetic administration tube into the intubation area of ​​the patient's oral cavity through the guide channel 3 formed by the repositioning actuator 2 and the guide part 11. After completing the anesthetic administration operation, the anesthetic administration tube is removed from the guide channel 3, and subsequent intubation operations can be carried out. If, during or after intubation, laryngoscope observation reveals cricoarytenoid joint dislocation requiring emergency repositioning, it is not necessary to remove the entire laryngoscope body 1 and guide part 11 from the patient's oral cavity. Simply manipulate the separable structure 4 to make the movable part 42 equipped with the repositioning actuator 2 relative to the guide part 11. When the connecting part 41 of the guide part 11 moves, the guide channel 3 formed by the repositioning execution structure 2 and the guide part 11 is released, allowing medical staff to directly manipulate the moving repositioning execution structure 2. Based on the specific location and degree of cricoarytenoid joint dislocation, the angle and position of its movement can be adjusted to perform repositioning operations on the dislocated cricoarytenoid joint. Throughout the repositioning process, the guide part 11 remains inside the patient's mouth, maintaining the original field of vision exposure. There is no need to readjust the laryngoscope position or repeatedly locate the cricoarytenoid joint as the target point. For example, in a clinical emergency scenario, if a patient experiences sudden anterior dislocation of the left cricoarytenoid joint after intubation, medical staff can quickly adjust the left repositioning execution structure 2 using the separable structure 4 to directly perform the repositioning operation without removing the intubation device or re-inserting the independent repositioning forceps. Compared to traditional methods, this significantly shortens the operation time and effectively improves the efficiency of cricoarytenoid joint repositioning.

[0045] Obviously, the laryngoscope body 1 has a guide portion 11, which is used to extend into the patient's oral cavity; the repositioning execution structure 2 is installed on the guide portion 11 and extends into the patient's oral cavity synchronously with the guide portion 11; the repositioning execution structure 2 and the guide portion 11 together form a guide channel 3, which is used to guide the anesthetic administration tube into the patient's oral cavity; thus, the synchronous insertion of anesthetic administration and the repositioning execution structure 2 is achieved, and medical staff do not need to insert the cricoarytenoid joint repositioning instrument separately into the patient's oral cavity after completing intubation anesthesia, reducing the number of instrument insertions, avoiding stimulation of the patient's oral tissues during multiple instrument insertions, and saving operation preparation time; in addition, the guide channel 3 can guide the anesthetic administration tube to the intubation area in the patient's oral cavity, eliminating the need for medical staff to repeatedly adjust the position of the administration tube, ensuring accurate anesthetic administration, and avoiding operation interruption due to inadequate anesthesia; based on the connecting portion 41 of the separable structure 4 being assembled on the guide portion 11, the separable structure 4 The movable part 42 is assembled to the repositioning execution structure 2, so that the repositioning execution structure 2 moves relative to the guide part 11 in the patient's oral cavity to perform cricoarytenoid joint repositioning operation; the guide channel 3 is released from enclosure as the repositioning execution structure 2 moves relative to the guide part 11; thus, without removing the laryngoscope body 1 and the guide part 11, the repositioning execution structure 2 can be moved flexibly in the patient's oral cavity by the separable structure 4, so that the repositioning operation can be carried out quickly, avoiding problems such as visual field obstruction and visual field re-exposure caused by repeated instrument entry and exit in the patient's oral cavity; at the same time, the guide part 11 always remains in the original position in the patient's oral cavity, eliminating the need for medical staff to reposition the operation target point, saving the tedious steps of target point repositioning, shortening the overall time of the repositioning operation, reducing the operation difficulty for medical staff, reducing operation errors caused by repeated positioning and instrument adjustment, thereby improving the operation efficiency of cricoarytenoid joint repositioning, reducing patient discomfort during operation, and improving the safety and convenience of operation.

[0046] See Figures 1-3 In this embodiment, in order to more effectively improve the operational efficiency of the cricoarytenoid joint reduction, preferably, the reduction execution structure 2 is provided with at least two, and each of the reduction execution structures 2 is connected to the corresponding separable structure 4; the two reduction execution structures 2 are respectively arranged on both sides of the guide portion 11 along its own width direction, and the two reduction execution structures 2 are respectively used to adapt to the reduction operation of the left and right cricoarytenoid joints of the patient;

[0047] The laryngoscope body 1 has a camera 12 and a display 13. The camera 12 is located at the end of the guide portion 11 for insertion into the patient's oral cavity. The display 13 is electrically connected to the camera 12.

[0048] By independently deploying the dual reduction execution structure 2, seamless switching between the left and right cricoarytenoid joint reduction operations can be achieved without changing the reduction instruments or adjusting the overall position of the device midway, reducing the time spent on instrument replacement and position adjustment. At the same time, the camera 12 can capture the actual state of the cricoarytenoid joint in the patient's mouth in real time and realize visual operation through the display 13, allowing medical staff to accurately locate the dislocated cricoarytenoid joint target point without relying on experience for blind operation, avoiding repeated operations caused by target point positioning deviation, improving the accuracy and success rate of reduction operation, and increasing the efficiency of cricoarytenoid joint reduction operation.

[0049] Furthermore, the reset execution structure 2 is provided with a guide rail 21, which extends along the length direction of the guide portion 11, and the guide rail 21 is slidably engaged with the movable portion 42;

[0050] The guide portion 11 has a movable groove 111, which extends through one side of the guide portion 11 along its width direction; the connecting portion 41 extends into the movable groove 111 through the opening of the movable groove 111 and slides in cooperation with the movable groove 111.

[0051] Through the linear sliding guidance of the guide rail 21 and the limiting constraint of the movable groove 111, the cooperation between the repositioning execution structure 2 and the separable structure 4 is made smoother and more stable. Medical staff can quickly and accurately adjust the position of the repositioning execution structure 2 in the length and width direction of the guide part 11 and quickly align it with the target point of the cricoarytenoid joint dislocation. At the same time, the groove-type cooperation structure can effectively limit the range of motion and avoid excessive movement of the repositioning execution structure 2 during operation, which may damage oral tissues. This makes the position adjustment operation more controllable and further improves the efficiency of the repositioning operation.

[0052] Furthermore, the connecting part 41 and the movable part 42 are rotatably connected by a universal hinge structure 43, so that the movable part 42 can rotate relative to the connecting part 41 at multiple angles.

[0053] The multi-angle rotation characteristics of the universal hinge structure 43 allow the repositioning actuator 2 to flexibly adapt to different directions of cricoarytenoid joint dislocation in clinical practice, such as anterior dislocation, posterior dislocation, and lateral dislocation. Without repeatedly adjusting the insertion angle and position of the laryngoscope body 1, the repositioning actuator 2 can fit the operating surface of the dislocated joint, shortening the time for adjusting the operating angle. At the same time, the multi-angle rotation makes the repositioning operation more in line with the physiological curvature of the human oral cavity, reducing the difficulty of operation and allowing medical staff to complete the repositioning action more easily, thus improving the efficiency of operation.

[0054] The universal joint structure 43 is preferably a spherical joint structure. Compared with the conventional joint structure, the spherical joint structure allows the repositioning execution structure 2 to perform more precise angle adjustments, which can be adapted to different degrees and different subtle angles of dislocation of the cricoarytenoid joint in clinical practice.

[0055] Furthermore, the guide portion 11 has a reset groove 112 at the periphery of the opening of the movable groove 111. The reset groove 112 extends along the length direction of the movable groove 111 and is connected to the movable groove 111. The movable portion 42 slides with the connecting portion 41, inserting into or disengaging from the reset groove 112.

[0056] The slot-type limiting structure of the reset groove 112 allows the reset execution structure 2 to be stably inserted into the reset groove 112 when it is not in the working state of intubation anesthesia, preventing it from shaking and interfering with the insertion and administration of the anesthesia administration tube, thus ensuring the smoothness of the intubation anesthesia process. When a reset operation is required, the movable part 42 can quickly slide out of the reset groove 112 along the movable groove 111 and directly enter the operation state, realizing a seamless switch between intubation anesthesia and cricoarytenoid joint reset operation without the need for additional structural unlocking steps, improving the continuity of operation and indirectly improving the efficiency of the reset operation.

[0057] Furthermore, of the reset groove 112 and the movable part 42, one is provided with a limiting magnetic attraction part 5 and the other is provided with a limiting magnetic attraction engagement part 6. The limiting magnetic attraction part 5 and the limiting magnetic attraction engagement part 6 are used to attract each other during the insertion process of the movable part 42 and the reset groove 112.

[0058] The guide portion 11 is provided with at least two positioning magnetic suction portions 113, which are arranged at intervals on opposite sides of the reset groove 112 along the length direction of the guide portion 11; the reset execution structure 2 is provided with at least two positioning magnetic suction engagement portions 22, and each positioning magnetic suction engagement portion 22 is attracted and positioned with the corresponding positioning magnetic suction portion 113.

[0059] The attraction between the limiting magnetic suction part 5 and the limiting magnetic suction mating part 6 makes the insertion of the movable part 42 into the reset groove 112 more secure, preventing the reset execution structure 2 from loosening and shaking due to the patient's oral movement and instrument movement during intubation anesthesia, thus ensuring structural stability in the non-working state. Through the magnetic attraction guidance and limiting effect of the positioning magnetic suction part 113 and the positioning magnetic suction mating part 22, when the guide part 11 and the reset execution structure 2 are inserted into the patient's oral cavity, it can effectively prevent the reset execution structure 2 from being dislodged from the reset groove 112 due to contact with the oral cavity wall, pharyngeal edge, etc. At the same time, the magnetic attraction force can form a flexible guiding traction, assisting the reset execution structure 2 to move more smoothly and accurately to the matching insertion position with the reset groove 112, eliminating the need for medical staff to manually adjust the alignment repeatedly in the oral cavity, reducing ineffective operations in the oral cavity, and improving the overall operation continuity and response efficiency.

[0060] See Figure 4 , Figure 5 Furthermore, the movable groove 111 is connected to the guide channel 3; the end of the connecting part 41 away from the movable part 42 is provided with an anti-displacement block 411, the anti-displacement block 411 protrudes into the guide channel 3, and the anti-displacement block 411 is used to abut against the outer wall of the anesthesia administration tube when the anesthesia administration tube passes through the guide channel 3.

[0061] By using the anti-displacement block 411 to abut and limit the movement of the anesthesia administration tube when it is inserted into the guide channel 3, the block protrudes from the guide channel 3 and abuts against the outer wall of the administration tube, thus limiting and constraining the connection part 41. This effectively prevents the repositioning execution structure 2 from accidentally dislodging from the repositioning groove 112 of the guide part 11 during the intubation anesthesia operation, ensuring that the repositioning execution structure 2 is always stably in a non-working insertion state and will not be loosened or displaced due to factors such as drug administration operation, patient oral movement or slight movement of the instrument. No additional inspection or adjustment of the position of the repositioning execution structure 2 is required by medical staff.

[0062] See Figure 1 Furthermore, the reset execution structure 2 includes a support arm 23 and a movable arm 24; the guide rail 21 and each of the positioning magnetic attraction parts 22 are all located on the support arm 23;

[0063] The support arm 23 and the movable arm 24 are rotatably connected by a hinge shaft 25, so that the movable arm 24 can move relative to the support arm 23;

[0064] The supporting arm 23 and the movable arm 24 together form a clamping structure 26 for inserting into the patient's mouth. The clamping structure 26 is used to clamp the cricoarytenoid joint.

[0065] The flexible rotation of the hinge shaft 25 allows the movable arm 24 to open and close freely relative to the support arm 23. The clamping structure 26 can stably clamp the dislocated cricoarytenoid joint according to its physiological shape, reducing the time spent on repeated clamping. At the same time, the opening and closing range of the clamping structure 26 can be flexibly adjusted, and the clamping force can be precisely controlled to prevent excessive clamping from damaging the cartilage and surrounding tissues of the cricoarytenoid joint.

[0066] See Figure 4 , Figure 6 , Figure 7 Furthermore, both the support arm 23 and the movable arm 24 are equipped with operating handles 7, each operating handle 7 having a mounting part 71, an operating part 72, and a rotating shaft 73; the two mounting parts 71 are detachably mounted to the end of the support arm 23 away from the clamping structure 26 and the end of the movable arm 24 away from the clamping structure 26, respectively; the operating part 72 is used for medical personnel to grip and apply force;

[0067] The operating part 72 is rotatably mounted to the mounting part 71 via the rotating shaft 73; the outer peripheral surface of the rotating shaft 73 is provided with a plurality of engaging teeth 731, which are arranged at intervals along the circumference of the rotating shaft 73; the mounting part 71 is correspondingly provided with an elastic engaging part 74, which has a latch 741, and the latch 741 alternately engages with each of the engaging teeth 731 as the rotating shaft 73 rotates.

[0068] With the detachable design of the operating handle 7, medical staff can quickly assemble or disassemble the handle according to their operating habits and clinical operation scenarios without the need for additional tools, thus shortening the preparation time. The rotating shaft 73 can directly drive the operating part 72 held by the medical staff to rotate. The medical staff can flexibly adjust the grip angle of the operating part 72 according to the actual posture of the intraoral repositioning operation, so as to adapt it to different force application directions, making the application of force more convenient and less strenuous, and reducing the difficulty of deep oral operation. At the same time, the rotation of the rotating shaft 73, together with the elastic engagement of the locking teeth 731 and the elastic locking tongue 741, can stably lock the adjusted angle of the operating part 72, effectively preventing the operating part 72 from rotating randomly during the repositioning force application process, making the application of force more stable and the direction of force more precise, further improving the efficiency and convenience of the repositioning operation.

[0069] Furthermore, both the end of the support arm 23 away from the clamping structure 26 and the end of the movable arm 24 away from the clamping structure 26 are provided with insertion slots 27, and each of the mounting parts 71 is inserted into the corresponding insertion slot 27.

[0070] The laryngoscope body 1 has an open receiving groove 14, and the inner wall of the receiving groove 14 has at least two receiving protrusions 141 corresponding to the two operating handles 7; the mounting part 71 has a receiving groove 711 adapted to the receiving protrusions 141, and each operating handle 7 can be selectively received in the receiving groove 14, and each receiving protrusion 141 is inserted into the corresponding receiving groove 711.

[0071] By using the storage function of the receiving groove 14 in conjunction with the insertion and fixation of the storage protrusion 141 and the storage groove 711, the operating handle 7 can be stably stored in the laryngoscope body 1 when not in use, avoiding loss or damage to the handle. At the same time, it makes the structure of the entire device more compact, facilitating the storage, carrying and clinical transport of instruments.

[0072] The overall clinical operation steps of this device are as follows: First, the medical staff holds the laryngoscope body 1 and slowly inserts the guide part 11, equipped with the repositioning execution structure 2, into the patient's mouth to the target intubation position. Then, the anesthetic administration tube is inserted into the guide channel 3, so that the outer wall of the administration tube abuts against the anti-displacement block 411 within the guide channel 3 to form a limit. After completing the intubation and anesthesia operation, the anesthetic administration tube is removed. If, after removal, the patient's cricoarytenoid joint is dislocated and requires emergency repositioning, the medical staff first removes the operating handle 7 from the receiving slot 14 of the laryngoscope body 1. Depending on whether the dislocated cricoarytenoid joint is on the left or right side, the operating handle 7 is correspondingly fitted into the insertion slot 27 at the end of the support arm 23 and movable arm 24 of the repositioning execution structure 2 on that side. Next, grasp the operating handle 7 and open the support arm 23 and movable arm 24 outwards. Use the opening force to break free from the magnetic attraction of the limiting magnetic part 5 and the limiting magnetic engagement part 6, and the positioning magnetic part 113 and the positioning magnetic engagement part 22, so that the movable part 42 of the reset execution structure 2 is disengaged from the reset groove 112.
