Expanding trachea cannula fixer

Abstract

The present invention relates to a medical device, particularly to an expanding trachea cannula fixer, which is composed of a pressure bar, a spring, a sleeve, a conical head, an expanding head and deforming seams, wherein, the sleeve is cylindrical, the inner side of the middle part of the sleeve is provided with one ring of step, which divides the inner part of the sleeve to an upper part and alower part. The bottom end of the sleeve is provided with an expanding head integrated with the sleeve, and the inner side surface of the expanding head is of a reverse conical shape. The side surfaceof the expanding head is provided with three deforming seams which generate an angle of 120 DEG with each other, and the bottom end of the pressure bar is of the reverse conical shape. The pressure lever is provided in the sleeve and is moveably fitted with the sleeve. The spring is sleeved to the lower part of the pressure bar. The expanding trachea cannula fixer not only can firmly fix the cannula, but also can send the cannula to the deeper part thereby greatly increasing the accuracy and stability of the surgery.

Description

technical field [0001] The invention relates to a medical device, in particular to a compression type endotracheal tube fixer. Background technique [0002] In heart or great vessel surgery, it is often necessary to intubate the blood vessel. In the current operation, the tube is directly taken by hand for intubation. When performing deep operations, the hand cannot reach into the deep part of the incision. At this time, since the tube is relatively soft, and the hand-held part is far away from the tip of the tube, the accuracy of intubation is greatly affected. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a compression-type endotracheal intubation holder capable of stably clamping the intubation tube. [0004] The solution to the technical problem of the present invention is: the compression-type endotracheal tube holder is composed of a compression rod, a spring, a sleeve, a conical head, an expanding hea...

Problems solved by technology

[0002] In heart or great vessel surgery, it is often necessary to intubate the blood vessel. In the current operation, the tube is directly held by the hand for intubation. When performing deep operations, the hand cannot reach into the deep part of the incision.

At this time, because the tube is relatively soft, and the hand-held part is far away from the tip of the tube, the accuracy of intubation is greatly affected.
