Laryngoscopy {LARYNGOSCOPE}

The present invention relates to a laryngoscope, and more particularly, it provides ease of insertion and extraction of the laryngoscope as well as the ease of insertion and extraction of anesthesia or oxygen tube used together with the laryngoscope, and also facilitates securing space and field of view. It relates to the provision of an improved laryngoscope to make it convenient.

The laryngoscope is used when surgery is performed on lesions such as the pharynx, larynx, airway, hypopharynx, and upper esophagus, and is mainly used to diagnose or remove tumorous lesions or other benign lesions occurring in the anatomical structure. It can also be used for endotracheal intubation.

Endotracheal intubation refers to the operation of placing a tube (tracheal tube) of a hard material such as metal or PVC with a certain length and inner diameter into the trachea using a laryngoscope.

The purpose of tracheal intubation as described above is to secure the patient's airway during anesthesia and surgery or when cardiopulmonary resuscitation is required, and for this purpose, endotracheal intubation is performed. The tube intubated through such tracheal intubation is used by connecting an anesthetic device or a ventilator.

Various types of laryngoscopes as described above have been developed and used, and a review of laryngoscopes to which this prior art is applied through the patent literature is as follows.

A typical hood mirror 100 includes a handle 101 provided in a bar type so that the operator can hold and control it by hand, and is coupled to the lower end of the handle 101 and inserted through the oral cavity so that the tip portion is positioned up to the larynx It is composed of a tube-type blade 102 that is made, and the blade 102 is configured to form an operation hole 103 so that the operation can be performed while visually checking the larynx.

The material of the laryngoscope 100 is made of a rigid material, such as a metal material or a highly durable plastic material, so that it is inserted through the oral cavity to be connected to the larynx. It would be natural to do so.

In the present invention, a blade opening/closing means 110 capable of opening or closing the lower portion of the blade 102 is provided to facilitate the insertion and removal of the laryngoscope 100 while visually confirming the inserted state while securing space. It is characterized in that the operation can be facilitated through the

The blade opening/closing means 110 is located on the upper side of the blade 102 based on the horizontal direction P1 with respect to the longitudinal axis center P of the blade 102 and the upper blade 111 does not move and Separately configured with a lower blade 112 moving with respect to the upper blade 111 located on the lower side of the blade 102 .

The lower blade 112 has an outer diameter portion 114 of the same shape as the inner diameter portion 113 of the upper blade 111, and when opened, the lower blade 112 is located on the bottom surface of the upper blade 111 to form a semicircle and It has the same shape and is positioned below the upper blade 111 when closed to maintain the same shape as a circle.

The upper blade 111 may be formed to protrude further downward than the horizontal direction (P1) standard, and the lower blade 112 may be configured in a half shape consistent with the horizontal direction (P1) standard, and vice versa, the lower blade ( 112) is larger than the upper blade 111, so that when closed, the horizontal direction (P1) parts of the upper and lower blades 111 and 112 are in a form that overlaps with a predetermined interval rather than simply abutting, so safety can be guaranteed. It is good to have

The thickness of the upper blade 111 and the lower blade 112 may be the same, but the thickness of the lower blade 112 is reduced within a range that does not interfere with durability because the objective is to secure a view and secure space. 111), it would be okay to make it thinner than the thickness.

Also, as in the second embodiment, the lower blade 112 is opened and closed by forming the lower blade 112 only in the front part (opposite to the handle) at the intermediate position P2 of the longitudinal axis center P of the blade 102. Only the area where the larynx is located that needs to secure space can be opened and closed to secure space and expose the treatment position.

The lower blade 112 is stably maintained by the blade guide 115 integrally formed with the upper blade 111 and allows the lower blade 112 to be opened and closed with respect to the upper blade 111 .

The blade guide 115 forms a tubular upper neck 116 at the rear portion of the upper blade 111 as in the third embodiment, and the upper neck 116 has the rear of the lower blade 112 . A lower neck 117 of a tubular or semicircular shape integrally formed with the part is coupled.

The lower neck 117 is naturally inserted into the upper neck 116, and if possible, on the contrary, the lower neck 117 may be configured such that the upper neck 116 is wrapped from the outside. will be.

A stopper that can prevent excessive insertion of the lower blade 112 by forming a protruding jaw 118 integral with the lower neck 117 at the rear end of the lower neck 117 to be in close contact with the rear end of the upper neck 116 . while performing the function of the handle for the opening and closing operation.

For the handle function, the protruding jaw 118 may be protruded to the rear long, or a separate handle may be integrally formed by the operator to hold the lower blade 112 and open and close the lower blade 112 with respect to the upper blade 111 while rotating in the forward and reverse directions. It would be natural to be able to do it.

As another example of the blade guide 115, as in the fourth embodiment, one or more guide rings 120 are integrally formed on the lower surface of the upper blade 111 at both ends or between both ends of the upper blade 111 to form a lower blade. (112) may be inserted and rotated with respect to the upper blade 111 to enable the opening and closing operation.

The upper neck 116 and the lower neck 117 and the rearmost guide ring 120 and the lower neck 117 have one locating protrusion 121 and one protrusion groove 122 on the joint surfaces of the lower neck 117 . Alternatively, it is better to form one or more so that the opening and closing positions can be determined.

The state of use of the laryngoscope 100 to which the technology of the present invention is applied as described above is as follows.

The operator holds the handle 101 and inserts the blade 102 through the recipient's oral cavity so that the front side of the blade 102 enters the hood. 100) is completed, and in this state, the necessary surgery is performed through the laryngoscope 100.

When inserting the blade 102, the lower blade 112 with respect to the upper blade 111 may be closed to maintain the same shape as the general laryngoscope 100, and may be inserted, or the lower blade with respect to the upper blade 111 ( 112) may be opened and the lower portion (bottom) of the blade 102 may be inserted while maintaining an open (exposed) state, and as another example, the lower blade 112 with respect to the upper blade 111 is inserted in a detached state. After the insertion is completed, the lower blade 112 may be coupled to the upper blade 111 .

After the insertion of the blade 102 is completed as described above, the operation may be performed by closing the lower blade 112 with respect to the upper blade 111 to keep the lower part of the upper blade 111 blocked. The lower blade 112 may be opened with respect to the upper blade 111 when it is determined that it is necessary to secure space and provide ease of operation.

The operation of opening and closing the lower blade 112 with respect to the upper blade 111 is as follows.

When the initial state is a closed state, the lower blade 112 rotates and is positioned on the lower surface of the upper blade 111 to form the treatment hole 103. In this state, if you want to switch to the open state Hold the lower neck 117 formed at the rear of the lower blade 1120 and rotate it.

Then, the lower blade 112 integrally having the lower rack 117 is accommodated in the upper neck 116 integrally formed at the rear of the upper blade 111 and rotates together with the rotating lower neck 117 to the upper blade. Since it is located on the bottom surface of (111), the bottom surface of the upper blade 111 can be maintained in an open state.

Conversely, if you want to switch from the open state to the closed state, if you hold the lower neck 117 and rotate it, the lower neck 117 maintained as the upper neck 116 rotates, and the lower blade integrated with the lower neck 117 ( 112) is to be converted into a form to block the lower opening at the bottom position of the upper blade (111).

Of course, the amount of opening or closing of the lower part of the upper blade 111 can be made by controlling the rotation angle of the lower blade 112 by the operator, and the operating state is the same even when the guide ring 120 is adopted. It would be natural to do it.

In addition, since the upper neck 116, the lower neck 117, and the guide ring 120 are formed with a positioning protrusion 121 and a protrusion groove 122 that can be engaged with each other, the movement is restricted after being adjusted. Therefore, the open and closed state can be maintained continuously, so that the operation is not disturbed.

By opening the lower blade 112 with respect to the upper blade 111, the space below the blade 102 is sufficiently secured, so it is easy to secure the operator's field of view, thereby providing convenience of the operation, and the lower blade 112. In the state where space is secured by opening the tube, it is possible to freely insert and remove the tube required during the procedure without physical pressure or damage to the recipient.

The present invention as described above makes it possible to open and close the blade so as to facilitate the insertion of the laryngoscope and secure the view and space of the larynx in the inserted state, thereby providing ease of operation and use of auxiliary equipment necessary for the procedure. can be conveniently performed, and there is no need for additional equipment during the procedure.
