Abstract

Tracheal puncture dilating pliers are formed by combining a left half plier and a right half plier. Each half plier is provided with a plier tip and a plier handle; the plier tip is a semi-circular cone with a curved arc; a positioning groove is arranged on the semi-circular cone of the plier tip; two small shafts are respectively arranged on the left half plier and the right half plier; cover plates are installed on the upper portion and the lower portion of each small shaft; the left half plier and the right half plier are connected into a whole by the cover plates; a positioning mechanism is arranged in the middle portion of the plier handle; and a locking mechanism is arranged at the tail portion of the plier handle. The tracheal puncture dilating pliers adopt double shafts to control the two half pliers to move, and motion trail of the plier tips tend to be parallel straight lines; as acting force direction of each plier handle is in an adduction type, a single hand can operate each plier handle; as the plier handles are not easy to be deformed, operation saves labor; the largest opening angle of the plier tips is controllable, a positioning ring is arranged on each plier tip to control puncturing depth and accurately clamp a tracheal wall; and a puncture hole can be expanded to a required size by means of extension force of the pliers, thereby reducing damage to a rear tracheal wall and circumferential tracheal tissues, and shortening surgery time.
