Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an operating assembly of a laryngeal mask, an installation method of the operating assembly and the laryngeal mask.
Background
The laryngeal mask as an supraglottic ventilation device belongs to an artificial respiratory tract, and is widely applied to clinic due to the advantages of simple and convenient operation, high success rate, small injury and the like after being invented in 1983. A laryngeal mask is an artificial airway device between a face mask and a tracheal cannula that allows a patient to maintain spontaneous breathing and also allows positive pressure ventilation.
The laryngeal mask without the visualization function is generally inserted into the body of a patient in a blind way, and because the details of the throat cannot be peeped during operation, an operator can only insert the laryngeal mask by hand feeling and experience. Blind insertion may cause inaccurate placement of the laryngeal mask, and inaccurate placement may cause a series of subsequent problems, such as failure to effectively isolate respiratory tract and digestive tract, resulting in incomplete sealing of the laryngeal mask, gas leakage, flatulence, reflux, and even aspiration of the patient; inaccuracies in position also increase the likelihood of intraoperative laryngeal mask movement. In addition, blind insertion can increase the probability of selecting an improper laryngeal mask. When one or more of the above problems occur, the operator has to re-angle the laryngeal mask within the patient or insert it multiple times, which can extend the procedure time, delaying the rescue of critically ill patients. And the oral mucus of the patient can be increased due to the trial insertion for many times, and the operation difficulty is increased accordingly. Moreover, repeated operation easily causes injury and bleeding of the throat of a patient, has large cardiovascular reaction, increases operation risk and the like.
In order to ensure the accuracy of the laryngeal mask placement position, an operator usually checks through various indirect means, such as observing the fluctuation of the chest, the lung compliance, auscultation whether air leakage exists or not, observing the neck bulge, monitoring PetCO2 (end-tidal carbon dioxide partial pressure), mouth opening observation and the like. There are some problems with using the soft visual lens directly. Firstly, the visual soft lens is a reusable instrument and directly contacts the internal tissues of a patient, so strict disinfection, such as soaking disinfection, is required, the disinfection is relatively long, the flow is complex, medical staff has to prepare a spare instrument during the disinfection, the use cost is objectively increased, and even then, certain cross infection risk exists; secondly, the cost of the visual soft lens is relatively high, and the visual soft lens does not belong to standby instruments which can be obtained randomly, for example, the visual soft lens is possibly lacked in some emergency airway treatment or part of basic medical institutions; third, the visual soft lens is mainly used for examination after the laryngeal mask is inserted or guiding the tracheal cannula to enter the glottis through the laryngeal mask, but the whole visual process is not realized in the laryngeal mask placing process, so that the repeated insertion of the laryngeal mask is difficult to effectively reduce.
In view of this, there is a need to achieve the visual function of the laryngeal mask itself, and a range of video laryngeal mask designs have emerged.
The invention provides a visual laryngeal mask (not temporarily disclosed), which is convenient to operate, and the visual device of the visual laryngeal mask is provided with an operation part, a part of components of the operation part are arranged in a control box, a knob in the operation part is arranged outside the control box, and the curvature of the far end of a visual tube provided with an image sensor can be adjusted by pulling the knob, so that the visual field direction of the far end of the visual tube can be adjusted.
However, in addition to the inherent characteristics of the video laryngeal mask which determine that the weight of the video laryngeal mask cannot be too heavy, the overall size of the operating portion and the control box is limited in order to avoid the airway and to allow for proper installation of the viewing tube. However, when the size of the control box is reduced, it becomes a problem how to smoothly install the operation portion into the control box.

In other embodiments, the first boss 2211 and/or the second boss 2221 need not be annular, such as one of the first boss 2211 and the second boss 2221 being annular and the other being a plurality of projections; alternatively, both the first and second bosses 2211 and 2221 may have a plurality of protrusions, but the width of the protrusion of one of the first and second bosses 2211 and 2221 is greater than the gap between the protrusions of the other.
In the embodiment, the distance a between the inner walls of the two opposite side walls of the box body 11 in fig. 3 is narrow, the accommodation space of the rotating assembly 22 is very limited, and the fingers of a person cannot extend into the box body 11 to mount the rotating assembly 22, so that the structure of the rotating assembly 22 cannot be complicated and the mounting is facilitated. In the present embodiment, the rotating assembly 22 is designed to be a cantilever-like structure, and only one end of the operating handle 21 needs to be connected with the first end of the rotating shaft 221 after passing through the mounting hole 111 on the side wall of the box 11. In order to facilitate connection between the operating handle 21 and the rotating shaft 221, in this embodiment, after one end of the operating handle 21 is sleeved on the rotating shaft 221, the operating handle 21 is fixed by the limit screw 25, specifically, as shown in fig. 5, a handle mounting hole 211 is provided on the operating handle 21 of this embodiment, a cross-sectional shape of the handle mounting hole 211 is a special-shaped hole having two straight sides similar to the second transmission surface 222a, a shape of the first end of the rotating shaft 221 is similar to the first transmission surface 221a, shaft holes (not shown) matched with the limit screw 25 are further provided on the operating handle 21 and the first end of the rotating shaft 221, respectively, when the operating handle 21 and the rotating shaft 221 are connected, the first end of the rotating shaft 221 penetrates through the handle mounting hole 211, the shaft holes on the operating handle 21 and the first end of the rotating shaft 221 are aligned with each other, and the limit screw 25 penetrates through the two. Further, as shown in fig. 4 and 5, in order to make the operation portion 2 have better operation performance, the operation portion 2 in this embodiment is further provided with a reset member and a bearing assembly 24, wherein the reset member may be a torsion spring 23, the bearing assembly 24 includes a bearing 242 and a bearing plate 241 having a shaft hole, the bearing 242 is installed in the shaft hole of the bearing plate 241, the steering wheel 222, the torsion spring 23, and the bearing 242 are sequentially sleeved on the rotating shaft 221 from the first end of the rotating shaft 221, and the first end of the bearing plate 241 is fixed on the side wall of the box body 11; the bearing plate 241 is provided with three fixing holes 2411, one end of the torsion spring 23 can be inserted into any one of the three fixing holes 2411, and the other end of the torsion spring 23 abuts against the steering wheel 222. The initial bending degree of the distal end (refer to fig. 16) of the image tube 300 can be adjusted by adjusting the pre-tightening force of the torsion spring through selecting different fixing holes 2411. It should be noted that the number of the fixing holes 2411 is limited to three, and may be less than three or more than three. When the operator pulls the operating handle 21, the operating handle 21 drives the rotating component 22 to rotate, and if the operator releases the operating handle 21, the torsion spring 23 can automatically reset the rotating component 22. Bearing assembly 24 may serve to provide more flexibility in the rotation of steerable wheel 222.
