一种喉镜a laryngoscope

技术领域technical field

本发明涉及可视喉镜领域，更具体地，涉及一种喉镜。The present invention relates to the field of video laryngoscopes, and more particularly, to a laryngoscope.

背景技术Background technique

可视喉镜是一种可视化的插管辅助的装置。现有的可视喉镜具有视野广的特点，但镜体不能变形，对张口受限、仰头受限、小下颌、咽腔狭小等患者可能会出现喉镜置入困难或声门暴露困难的问题，导致插管失败，甚至威胁到患者的生命安全。A video laryngoscope is a visual intubation-assisted device. The existing video laryngoscope has the characteristics of wide field of view, but the mirror body cannot be deformed, and it may be difficult to insert the laryngoscope or expose the glottis for patients with limited mouth opening, limited head lift, small mandible, and small pharyngeal cavity. problems, leading to failure of intubation and even threatening the life of patients.

软性可视喉镜的镜头方向可通过镜体前端的蛇骨结构灵活地改变，但蛇骨结构提供给软性可视喉镜的压舌板上抬的力量较小，难以在会厌谷将会厌抬起而暴露声门，常常需要将压舌板伸入会厌下方将会厌抬起，操作难度大，且操作繁琐。而且，软性可视喉镜的镜体较软，不能在口腔内上提将舌体抬起而扩大口咽腔空间，气管插管操作时常常需要专门的引导系统引导。The direction of the lens of the flexible video laryngoscope can be flexibly changed by the snake bone structure at the front end of the scope body, but the snake bone structure provides a small lifting force for the tongue depressor of the flexible video laryngoscope, which is difficult to move in the epiglottis valley. The epiglottis is raised to expose the glottis, and it is often necessary to insert the spatula under the epiglottis to raise the epiglottis, which is difficult and cumbersome to operate. Moreover, the flexible video laryngoscope has a soft mirror body and cannot lift the tongue body in the oral cavity to expand the oropharyngeal cavity space. Special guidance systems are often required for tracheal intubation.

因此，如何提供一种既灵活，又可提供更大的上抬力量，方便插管的喉镜成为本领域技术人员所要解决的重要技术问题。Therefore, how to provide a laryngoscope that is both flexible and can provide greater lifting force and facilitate intubation has become an important technical problem to be solved by those skilled in the art.

镜体机构包括支撑组件和外套(图中未示出)。支撑组件包括镜体3和牵引件(图中未示出)，外套套设在镜体3外。外套可起到辅助支撑支撑组件以及密封支撑组件的作用。具体实施时，外套包裹在支撑组件外。外套可例如为编网和树脂等材质。The mirror body mechanism includes a support assembly and a casing (not shown in the figure). The support assembly includes amirror body 3 and a pulling member (not shown in the figure), and the outer sleeve is sleeved outside themirror body 3 . The jacket may function to assist in supporting the support assembly as well as sealing the support assembly. In a specific implementation, the outer jacket is wrapped around the support assembly. The outer jacket can be made of, for example, woven mesh and resin.

镜体3包括镜头件31和连接组件。镜头件31上设有摄像头311和光源312。通过光源312对患者喉部进行照明，并通过摄像头311获取图像。Themirror body 3 includes alens element 31 and a connecting assembly. Thelens member 31 is provided with acamera 311 and alight source 312 . The larynx of the patient is illuminated by thelight source 312 , and images are acquired by thecamera 311 .

连接组件位于镜头件31和手柄1之间，且连接组件包括至少一个连接件32。连接组件可起到连接镜头件31和手柄1的作用，以及起到协助或控制镜体3弯曲变形的作用。The connecting assembly is located between thelens member 31 and the handle 1 , and the connecting assembly includes at least one connectingmember 32 . The connecting assembly can play the role of connecting thelens element 31 and the handle 1 , and can play the role of assisting or controlling the bending deformation of thelens body 3 .

当连接组件只有一个连接件32时，连接件32用于将镜头件31和手柄1直接连接到一起，镜头件31相对于连接件32的位置可发生变化，通过镜头件31实现镜体3的弯曲变形。When the connecting assembly has only one connectingpiece 32, the connectingpiece 32 is used to directly connect thelens piece 31 and the handle 1 together, the position of thelens piece 31 relative to the connectingpiece 32 can be changed, and themirror body 3 can be connected by thelens piece 31. Bending deformation.

当连接组件包括两个及以上的连接件32时，多个连接件32可配合在一起，实现镜体3的弯曲变形。When the connecting assembly includes two or more connectingpieces 32 , the plurality of connectingpieces 32 can be matched together to realize the bending deformation of themirror body 3 .

相邻连接件32的相邻侧壁的一端相连接。上述相邻连接件32的相邻侧壁的连接处位于各侧壁的端部，以使得相邻连接件32在发生相对运动时可在侧壁的端部处相互支撑，达到镜体3在弯曲变形过程中更加稳定的效果。而且，相邻连接件32的连接处位于相邻侧壁的端部还有利于增加连接件32的活动范围，减少相邻连接件32之间的干涉。当相邻连接件32的相对位置发生变化时，相邻的连接件32以连接件32之间的连接处为转轴发生相对转动。具体实施时，相邻连接件32之间的连接可通过连接轴、连接片等连接方式实现。One ends of adjacent side walls of adjacent connectingpieces 32 are connected. The connection of the adjacent side walls of the above-mentioned adjacent connectingpieces 32 is located at the end of each side wall, so that the adjacent connectingpieces 32 can support each other at the ends of the side walls when the relative movement occurs, so that themirror body 3 is at the end of the side wall. More stable effect during bending deformation. Moreover, the connection of the adjacent connectingpieces 32 at the ends of the adjacent side walls is also beneficial to increase the moving range of the connectingpieces 32 and reduce the interference between the adjacent connectingpieces 32 . When the relative positions of the adjacent connectingmembers 32 change, the adjacent connectingmembers 32 rotate relative to each other with the connection between the connectingmembers 32 as the rotation axis. During specific implementation, the connection between the adjacent connectingpieces 32 may be realized by connecting means such as connecting shafts, connecting pieces and the like.

此外，相邻连接件32的相邻侧壁的连接端部之间可具有一定的距离，以增加连接件32的活动范围，使得镜体3的弯曲变形更加灵活。In addition, there may be a certain distance between the connecting ends of the adjacent side walls of the adjacent connectingpieces 32 to increase the movable range of the connectingpieces 32 and make the bending deformation of themirror body 3 more flexible.

镜头件31与毗邻的连接件32的相邻侧壁的一端相连接。镜头件31与毗邻的连接件32的连接处位于镜头件31和连接件32的相邻侧壁的端部，可使得镜头件31和连接件32在发生相对运动时在相邻侧壁的端部处相互支撑，达到镜体3在弯曲变形过程中更加稳定的效果。而且，镜头件31和连接件32的连接处位于相邻侧壁的端部还有利于增加镜头件31的活动范围，减少镜头件31和连接件32之间的干涉。当镜头件31相对于连接件32的位置发生变化时，镜头件31以镜头件31和连接件32之间的连接处为转轴发生相对转动。具体实施时，镜头件31和连接件32之间的连接可通过连接轴、连接片等连接方式实现。Thelens piece 31 is connected with one end of the adjacent side wall of the adjacent connectingpiece 32 . The connection between thelens piece 31 and the adjacent connectingpiece 32 is located at the end of the adjacent side wall of thelens piece 31 and the connectingpiece 32, so that thelens piece 31 and the connectingpiece 32 can be located at the end of the adjacent side wall when the relative movement occurs. The parts support each other to achieve a more stable effect of themirror body 3 during the bending deformation process. Moreover, the connection between thelens member 31 and the connectingmember 32 is located at the end of the adjacent side wall, which is also beneficial to increase the moving range of thelens member 31 and reduce the interference between thelens member 31 and the connectingmember 32 . When the position of thelens member 31 relative to the connectingmember 32 changes, thelens member 31 rotates relatively with the connection between thelens member 31 and the connectingmember 32 as the rotation axis. In a specific implementation, the connection between thelens member 31 and the connectingmember 32 can be realized by connecting means such as a connecting shaft, a connecting piece, or the like.

此外，镜头件31和连接件32的相邻侧壁的连接端部之间可具有一定的距离，以增加镜头件31的活动范围，使得镜体3的弯曲变形更加灵活。In addition, there may be a certain distance between the connecting ends of the adjacent side walls of thelens member 31 and the connectingmember 32 to increase the movable range of thelens member 31 and make the bending deformation of themirror body 3 more flexible.

牵引件用于控制镜头件31和/或连接件32的位置，以改变镜体3的弯曲角度。牵引件可例如为拉绳，通过牵引件可对镜头件31和/或连接件32施力，牵拉镜头件31和/或连接件32，使得镜头件31和/或连接件32的位置发生变化。或者，牵引件可例如为连接在镜头件31和连接件32上的拉杆，通过电动或手动驱动机构驱动拉杆，使得镜头件31的位置发生变化。The pulling member is used to control the position of thelens member 31 and/or the connectingmember 32 to change the bending angle of thelens body 3 . The pulling member can be, for example, a pulling rope, through which thelens member 31 and/or the connectingmember 32 can be exerted force, and thelens member 31 and/or the connectingmember 32 can be pulled, so that the position of thelens member 31 and/or the connectingmember 32 can occur. Variety. Alternatively, the pulling member can be, for example, a pull rod connected to thelens member 31 and the connectingmember 32 , and the pull rod is driven by an electric or manual driving mechanism to change the position of thelens member 31 .

具体实施时，牵引件的一端可与镜头件31固定连接，牵引件的另一端可穿过连接件32及手柄1后露出于手柄1外，以使得操作者可对牵引件直接施力。In specific implementation, one end of the pulling member can be fixedly connected with thelens member 31, and the other end of the pulling member can pass through the connectingmember 32 and the handle 1 and be exposed outside the handle 1, so that the operator can directly exert force on the pulling member.

本发明的喉镜可具有放松状态和受力状态两种状态，具体说明如下：The laryngoscope of the present invention can have two states: a relaxed state and a stressed state, and the details are as follows:

在放松状态下，镜头件31和连接件32均未受到牵引件的作用力，镜头件31和连接件32没有在外力的作用下位置发生变化。此时，镜头件31上与连接件32连接的侧壁和连接件32上与镜头件31连接的侧壁以及相邻连接件32的相邻侧壁之间可保持一定的间距且没有力的相互作用。In the relaxed state, neither thelens part 31 nor the connectingpart 32 is subjected to the force of the pulling part, and the position of thelens part 31 and the connectingpart 32 does not change under the action of external force. At this time, a certain distance can be maintained between the side wall of thelens piece 31 connected with the connectingpiece 32 and the side wall of the connectingpiece 32 connected with thelens piece 31 and the adjacent side walls of the adjacent connectingpiece 32 without any force. interaction.

在受力状态下，镜头件31受到牵引件的作用力，镜头件31相对于毗邻的连接件32的位置发生变化，镜头件31和毗邻的连接件32的相邻侧壁相贴合和/或镜头件31和毗邻的连接件32的相邻侧壁之间存在相互的作用力，使得镜头件31在毗邻的连接件32的支撑作用下运动。相邻的连接件32的相邻侧壁相贴合和/或相邻的连接件32的相邻侧壁之间存在相互的作用力，使得相邻的连接件32在彼此的支撑作用下运动。In the stressed state, thelens member 31 is subjected to the force of the traction member, the position of thelens member 31 relative to the adjacent connectingmember 32 changes, and thelens member 31 and the adjacent side walls of the adjacent connectingmember 32 are abutted and/or Or there is a mutual force between thelens piece 31 and the adjacent side walls of the adjacent connectingpiece 32 , so that thelens piece 31 moves under the support of the adjacent connectingpiece 32 . Adjacent side walls of adjacent connectingpieces 32 abut against each other and/or there is a mutual force between adjacent side walls of adjacent connectingpieces 32, so that adjacent connectingpieces 32 move under the support of each other .

当喉镜处于受力状态时，镜体3的弯曲角度可根据牵引件的作用力的变化灵活地进行调整。由于镜头件31可被毗邻的连接件32所支撑，和/或相邻的连接件32可彼此相互支撑，弯曲的镜体3可提供更大的上抬力量，实现在会厌谷将会厌直接抬起而暴露声门的目的。When the laryngoscope is in a stressed state, the bending angle of thescope 3 can be flexibly adjusted according to the change of the force of the traction member. Since thelens piece 31 can be supported by the adjacent connectingpieces 32, and/or the adjacent connectingpieces 32 can support each other, thecurved mirror body 3 can provide a greater lifting force, so that the epiglottis can be directly lifted in the epiglottis valley. Rise to expose the purpose of the glottis.

本发明的喉镜在使用时，先将镜体3插入患者的口腔，根据弯曲角度需求控制牵引件，使镜体3发生不同程度的弯曲。在镜头件31上的摄像头看到会厌后，通过牵引件对镜体3的作用使镜体3弯曲，从而将会厌挑起暴露声门。在暴露声门的过程中，还可以适当上提喉镜以协助暴露声门，并增加口咽腔的空间，从而有助于气管导管的插入。When the laryngoscope of the present invention is used, thescope body 3 is first inserted into the oral cavity of the patient, and the traction member is controlled according to the bending angle requirements, so that thescope body 3 is bent to different degrees. After the camera on thelens member 31 sees the epiglottis, themirror body 3 is bent by the action of the traction member on themirror body 3, so that the epiglottis is provoked to expose the glottis. In the process of exposing the glottis, the laryngoscope can also be appropriately raised to assist in exposing the glottis and increase the space of the oropharyngeal cavity, thereby facilitating the insertion of the endotracheal tube.
