Description

Technical Field

[0001] The present invention relates to a visible laryngeal mask, and particularly to a structure of a visualizer. Background Art

[0002] For visual medical devices, the visualization function of the laryngeal mask medical device is realized by an endoscope cooperating with the medical device. When cooperating, it is necessary to hold the endoscope by hand to ensure that the front camera of the endoscope is always closely attached to the observation window of the laryngeal mask to ensure stable images. For example, a visible laryngeal mask has a visible cavity. The distal end of the visible cavity forms an observation window and the proximal end forms an insertion port. When in use, it is necessary to insert the endoscope into the visible cavity. However, during the entire visual process, the doctor needs to hold the endoscope by hand, which is inconvenient to operate; and the endoscope is extremely likely to shift, resulting in an unstable visual process.

[0003] CN110694156A discloses a laryngeal mask assembly. The laryngeal mask assembly includes: a laryngeal mask. The laryngeal mask forms a visible cavity along its longitudinal extension direction. The distal end of the visible cavity forms an observation window and the proximal end forms an insertion port. At least one limiting and cooperating part is formed in the visible cavity. The handle controls the camera assembly to be detachably cooperated in the visible cavity through a connecting line, so that the camera assembly can reach the observation window at the distal end of the visible cavity. The handle is provided with a limiting part that is in limiting cooperation with the limiting and cooperating part. In this way, the handle is detachably cooperated in the insertion port. Specifically, the handle is connected to the laryngeal mask joint through the cooperation of a ball and a socket. In addition, a limiting protrusion and a limiting groove are also provided for limiting; that is, in the form of snap connection. By utilizing the elastic characteristics of the small ball inside the visualizer handle, the snap connection boss of the handle is snapped with the limiting groove of the laryngeal mask joint, so as to realize the installation and fixation of the visualizer. However, during the clinical use process, the user is likely to collide with the visualizer handle, making the snap connection between the handle and the joint unstable, so that the handle is easily disengaged. Summary of the Invention

[0004] In view of the foregoing technical problems, the present invention provides a visualizer structure with an anti-disconnection function. The structure includes a laryngeal mask connector and a visualizer. The laryngeal mask connector includes a connecting plate, a main insertion tube installed on the connecting plate for connecting with the laryngeal mask ventilation tube, and a visual insertion tube for connecting with the laryngeal mask visual cavity. The main insertion tube penetrates the connecting plate from top to bottom. The visual insertion tube forms a socket for the connecting rod to enter. The visualizer includes a handle, a connecting wire connected to the handle, and a camera assembly connected to the distal end of the connecting wire. The handle includes a handle body and a connecting rod connected to the handle body. The handle body is adapted to insert the connecting rod into the visual insertion tube in a pluggable manner. The handle body abuts against the upper surface of the connecting plate. An arc-shaped concave surface matching the outer wall of the main insertion tube is formed on the side wall of the handle body. Elastic limiting columns are provided on the arc-shaped concave surface. When the arc-shaped concave surface of the handle body approaches the main insertion tube; a first limiting member is formed on the handle body, and a first limiting groove for cooperating with the first limiting member is formed on the laryngeal mask connector. The rotation of the arc-shaped concave surface of the handle body towards the main insertion tube drives the first limiting member to be in limiting cooperation with the first limiting groove, thereby realizing the limiting of the handle and the main connector.

[0005] In some embodiments, a second limiting member is formed on the connecting rod, and a second limiting groove for cooperating with the second limiting member is formed on the visual insertion tube. The rotation of the arc-shaped concave surface of the handle body towards the main insertion tube drives the second limiting member to be in limiting cooperation with the second limiting groove.

[0006] In some embodiments, a second limiting member is formed on the connecting rod, and a second limiting groove for cooperating with the second limiting member is formed on the visual insertion tube. The rotation of the arc-shaped concave surface of the handle body towards the main insertion tube drives the first limiting member to be in limiting cooperation with the first limiting groove.

[0007] In some embodiments, the second limiting member includes a second side wall and a second blocking block connected to the second side wall. The second side wall extends radially outward from the outer periphery of the connecting rod, and the second blocking block is arranged on the radial outer side of the connecting rod; the visual insertion tube forms an axially extending second limiting groove for the second limiting member to be inserted along the axial direction from the socket. The second limiting groove is open at the bottom side of the connecting plate compared with the bottom side of the connecting plate. The rotation of the connecting rod can drive the second blocking block to rotate and abut against the bottom side of the connecting plate.

[0008] In some embodiments, the first limiting member is arranged at the bottom of the handle body. The first limiting member includes a second blocking wall extending axially and a first blocking wall extending perpendicular to the second blocking wall;

[0009] The first limiting groove includes a second limiting surface for forming radial limiting with the second blocking wall and a first limiting surface for forming axial limiting with the first blocking wall.

[0010] In some embodiments, the first limiting groove has an entrance for the first limiting member to extend into and out of.

[0011] In some embodiments, the first limiting member is arranged in an L shape.

[0012] In some embodiments, the connecting plate extends outward to form a limiting retaining wall. The free end of the limiting retaining wall bends towards the inner side of the connecting plate to form an entrance. A first limiting groove communicating with the entrance is formed between the connecting plate and the limiting retaining wall. The rotation of the handle body drives the first limiting member to enter the first limiting groove from the entrance.

[0013] In some embodiments, an inner wall is formed on the connecting plate in the direction towards the limiting retaining wall. The limiting retaining wall and the inner wall define the first limiting groove, and the first and second limiting grooves extend in a bent manner compared to the entrance.

[0014] In some embodiments, the limiting retaining wall includes an L-shaped retaining wall and a hook portion formed at the free end of the L-shaped retaining wall. The hook portion and the inner wall constitute the first limiting groove, and the gap defined between the hook portion and the side wall of the connecting plate constitutes an entrance suitable for the second retaining wall to enter and exit.

[0022] In the description of the present invention, it should be noted that unless otherwise specified and defined, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific situations.

[0023] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides a visualizer structure with an anti-disconnection function. The structure includes a laryngeal mask connector and a visualizer. The laryngeal mask connector includes a connecting plate 10, a main cannula 20 installed on the connecting plate, and two side cannulas 31, 32. The two side cannulas 31, 32 are formed on both sides of the main cannula. The main cannula 20 penetrates the connecting plate 10 from top to bottom. The two side cannulas 31, 32 extend axially downward from the connecting plate. Among them, the main cannula 20 is used to connect with the laryngeal mask ventilation tube. One of the side cannulas is a visual cannula 32 for connecting with the laryngeal mask visual cavity. The visual cannula 32 forms a socket 320 for a connecting rod to enter. That is, the laryngeal mask connector is adapted to be connected with the laryngeal mask body and has ventilation and visual functions.

[0024] The visualizer includes a handle, a connecting line connected to the handle, and a camera assembly connected to the distal end of the connecting line. The handle includes a handle body 50 and a connecting rod 60 connected to the handle body. The handle body 50 is used to insert the connecting rod 60 into the visual cannula 32 in a pluggable manner. The handle body abuts against the upper surface of the connecting plate 10. An arc-shaped concave surface 501 matching the outer wall of the main cannula is formed on the side wall of the handle body 50. In this way, the side wall of the handle body 501 can be attached to the outer wall of the main cannula 20.

[0025] In some embodiments, elastic limiting posts 502 are provided on the arc-shaped concave surface facing the outer wall of the main cannula. In some embodiments, a first limiting member 81 is formed on the handle body, and a first limiting groove 82 is formed on the main joint for cooperating with the first limiting member 81. When the arc-shaped concave surface of the handle body rotates towards the main cannula, the elastic column is compressed to generate a thrust force to promote the limiting cooperation between the first limiting member and the first limiting groove, thereby realizing the limiting of the handle and the main joint.

[0026] Further preferably, a second limiting member 71 is formed on the connecting rod 60, a second limiting groove 72 cooperating with the second limiting member is formed on the visible cannula, the arc-shaped concave surface of the handle body faces the main cannula and rotates, and the driving force of the elastic limiting post drives the second limiting member to be in limiting cooperation with the second limiting groove and the first limiting member to be in limiting cooperation with the first limiting groove, thereby realizing the limitation of the handle and the connecting plate in the axial and radial directions. In this way, through these two groups of limiting structures, the handle and the main joint can be limited in both the radial and axial directions, and the limiting cooperation between the handle and the main joint is more stable, avoiding the handle being disengaged when the handle is accidentally touched.

[0027] When the visible handle is inserted into the main joint, the connecting rod of the visible handle is smoothly inserted into the visible cannula. The elastic limiting post on the handle body will be compressed by the outer wall of the main cannula. The compressed elastic limiting post will generate an outward thrust on the handle body, and this thrust can cause the second limiting member to be in limiting cooperation with the second limiting groove. That is, the size of the second limiting groove allows the second limiting member to slide into it along the axial direction, and the thrust generated by the elastic limiting post can drive the second limiting member to rotate so as to be in stop cooperation with the second limiting groove. In some embodiments, please refer to Figure 3 and Figure 4 , the second limiting member 71 includes a second side wall 711 and a second stopper 712 connected to the second side wall. The second side wall 711 extends radially outward from the outer periphery of the connecting rod 60, and the second stopper 712 is arranged on the radial outer side of the connecting rod 60; the visible cannula 32 forms an axially extending second limiting groove 72 at the socket 320 for the second limiting member to be inserted along the axial direction. The second limiting groove is open compared to the bottom side of the connecting plate. In this way, after the second limiting member 71 enters the second limiting groove 72 along the axial direction, when the arc-shaped concave surface 501 of the handle body 51 approaches the side wall of the main cannula 20, the connecting rod 60 rotates until the second stopper 712 rotates radially along the second limiting groove 72 to abut against the bottom side of the connecting plate 10, thus realizing the limitation in the axial direction; further, the side part of the second stopper 72 also has a stop limit with the side wall of the second limiting groove.

[0028] In some embodiments, please refer to Figure 3 and Figure 4 , the first limiting member 81 is arranged at the bottom of the handle body 50. The first limiting member includes a second blocking wall 811 extending axially and a first blocking wall 812 extending perpendicular to the second blocking wall; the first limiting groove includes a second limiting surface forming a radial limit with the second blocking wall and a first limiting surface forming an axial limit with the first blocking wall. In this way, the limitation of the handle body and the connecting plate in the radial and axial directions is realized. When the handle body is accidentally collided, its first limiting member and the first limiting groove prevent the handle body from coming out.

[0029] In some examples, the first limiting groove 82 has an entrance 821 for the first limiting member 81 to extend into and withdraw from; specifically, the first limiting member is arranged in an L shape.

[0030] In this embodiment, the structural form of the first limiting groove is as follows: the connecting plate extends outward to form a limiting retaining wall 91, the free end of the limiting retaining wall 91 bends toward the inner side of the connecting plate to form an entrance 821, a first limiting groove 82 communicating with the entrance is formed between the connecting plate and the limiting retaining wall, and the first limiting groove 82 bends and extends from the entrance 821.

[0031] In a specific example, an inner wall 92 is formed on the connecting plate in the direction toward the limiting retaining wall, and the limiting retaining wall 91 and the inner wall 92 define the first limiting groove 82; the limiting retaining wall includes an L-shaped retaining wall 911 and a hook portion 912 formed at the free end of the L-shaped retaining wall, and the first limiting groove is formed between the hook portion 912 and the inner wall 92; and a gap 18 defined between the hook portion 912 and the side wall of the connecting plate 10 forms an entrance 821 suitable for the second retaining wall to enter and exit.

[0032] The visualizer structure provided by the present invention improves the connection structure between the handle and the laryngeal mask adapter, has stable buckling, and eliminates the problem that the handle is easily disconnected.

[0033] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
