The present invention provides a blade 100 for a trachea cannula, which comprises: a blade body 10 and an instrument channel 20 mounted on the blade body 10. The instrument channel 20 is hollow and tubular and is integrally injection molded. For example, the instrument channel 20 is fixedly mounted on the blade body 10 by means of bonding. Endoscopic instruments and the like (not shown) are inserted through the instrument channel 20 to perform treatment, sampling and the like

The blade body 10 is integrally formed, and may be made of plastic or metal. The blade body 10 is divided into three sections: a front portion 1, a rear portion 2 and a trunk portion 3 located between the front portion 1 and the rear portion 2. It will be appreciated that in practice, the front portion 1 will be the deepest portion of the mouth and throat of the doctor, and the rear portion 2 will remain outside the mouth of the doctor.

The front portion 1 comprises in particular a side wall 11, a bottom wall 12, a stop wall 13 and a rear wall 14. Wherein the bottom wall 12 extends laterally from the bottom end of the side wall 11. A stopper wall 13 extends laterally from the top end of the side wall 11. The rear wall 14 defines the rear boundaries of the side wall 11, the bottom wall 12 and the stopper wall 13, and partitions the front portion 1 and the trunk portion 3. The rear wall 14 is provided with a bore 15 through which an instrument channel 20 extends. Referring to fig. 2 and 5 in combination, the front end of instrument channel 20 is inserted into through-hole 15

With combined reference to fig. 2 and 4, the stop wall 13 is triangular in shape, the base of which lies in the plane of the rear wall 14. This configuration not only shields the through hole 15 from the top side to some extent, but also ensures a sufficiently wide space in front of the through hole 15, thereby facilitating the treatment and sampling operations of the endoscopic instrument inserted through the instrument channel 20.

The rear portion 2 is provided at a rear end with a stop 24 for cooperation with the instrument channel 20, the stop 24 having a slot 25 for insertion of the instrument channel 20 therein. Referring to fig. 1 and 3, the rear end of the instrument channel 20 is inserted into the slot 25.

The trunk portion 3 comprises in particular a side wall 31, a bottom wall 32 and a top wall 33. Wherein the bottom wall 32 extends laterally from the bottom end of the side wall 31. The top wall 33 extends laterally from the top end of the side wall 11. The side walls 31, bottom wall 32 and top wall 33 enclose a receiving slot 34 for receiving the body of the instrument channel 20. Referring to fig. 4, 6 and 7, the top wall 33 is wider at the rear and narrower at the front. The position of the through hole 15 is located at the center in the width direction of the front end edge of the top wall 33.

It is worth mentioning that the position of the perforation 15 is located in the center of the front portion 1. This configuration facilitates treatment, sampling, etc. of an endoscopic instrument inserted through instrument channel 20.

It should be understood that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same, and those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some technical features; and such modifications and substitutions are intended to be included within the scope of the appended claims.
