Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The following describes an implementation of the tracheal cannula distractor according to the present invention in detail with reference to fig. 1-4. According to the embodiment of the utility model provides a trachea cannula struts ware can strut, prop the circle to being stung flat stinging closed trachea cannula. Thus, the endotracheal tube distractor includes a sheath 100 and a drive rod 200.

Specifically, the sleeve body 100 has a straight cylinder section 101 and a cone section 102, the top end of the cone section 102 is provided with an opening 1021 and is suitable for inserting a tracheal cannula, the bottom end of the cone section 102 is connected with the straight cylinder section 101, the side wall of the cone section 102 is provided with a gap 1022 for the side wall of the cone section to elastically stretch and contract along the radial direction, and the inner wall of the cone section 102 is provided with an internal thread 1023; the driving rod 200 has a head 201 and a handle 202, the outer surface of the head 201 is provided with an external thread 2011 adapted to screw in the inner wall of the cone segment 102 and to press the inner wall of the cone segment 102 in a radial direction to elastically expand, and the handle 202 is connected to the head 201 and adapted to drive the head 201 to screw in the cone segment 102 by rotation.

In other words, the sheath body 100 can be inserted into an endotracheal tube, and the insertion end is a tapered section 102, and the tapered section 102 can be inserted into the endotracheal tube which is bitten flat and closed by using the characteristics of thin one end and thick another end. Furthermore, the driving rod 200 is insertable into the sleeve body 100, and by the thread fit between the external thread on the conical head 201 and the internal thread in the conical section 102, the rotation of the handle 202 can be converted into the precession of the conical head 201, so as to gradually expand the sidewall of the conical section 102 in the radial direction; then the side wall can extrude the tube wall of the tracheal cannula in the process of opening so that the occluded and closed position of the tracheal cannula can be gradually opened and rounded.

Therefore, according to the utility model discloses trachea cannula struts ware, set up gap 1022 and internal thread 1023 through the cone section 102 of the cover body 100, the conical head 201 of actuating lever 200 sets up external screw thread 2011 for when rotatory actuating lever 200, conical head 201 revolves and then extrudes the lateral wall of cone section 102 in cone section 102, makes lateral wall elasticity open and expand tightly in trachea cannula, thereby struts, the circle to trachea cannula. In addition, the trachea cannula can be slowly unfolded through repeated screwing and unfolding matching of the internal thread and the external thread, and the integrity of the trachea cannula is prevented from being damaged in the unfolding operation of the trachea cannula. Thereby avoiding the waste of equipment resources, avoiding the damage of the esophagus and the trachea of the patient caused by frequent trachea intubation and increasing the life risk of the patient.

Wherein, the overall length of the driving rod 200 is longer than that of the sheath body 100.

In addition, the sleeve body 100 can be made of plastic material, so that the tracheal cannula is not easy to damage when the sleeve body 100 is inserted into the tracheal cannula. Meanwhile, the sleeve body 100 made of plastic material has certain elasticity, and can be well matched with the tracheal cannula. The outer diameter of the straight cylinder section 101 can be made into different models according to actual conditions, generally, the inner diameter of the trachea cannula is 2.5mm-8mm, and the outer diameter of the straight cylinder section 101 is set to be slightly smaller than the inner diameter of the trachea cannula so as to improve the opening and rounding effects.

According to some embodiments of the present invention, the gaps 1022 are at least two and are uniformly spaced in the circumferential direction of the cone segment 102. Wherein, it can be understood that, set up gap 1022 on the lateral wall of cone section 102, set up opening 1021 at the tip of cone section 102 for the lateral wall of cone section 102 can be strutted, and the circumference interval equipartition can strut, prop the circle to trachea cannula evenly, guarantee that trachea cannula can be rectified the circle. Of course, in other examples, the end of the cone segment 102 may be non-open and extend to the end of the cone segment 102 through the slit 1022, that is, one end of the cone segment 102 is connected to the straight cylinder segment 101, and the other ends are spaced apart and disconnected from each other along the circumference of the cone segment 102.

According to a further embodiment of the present invention, the gap 1022 divides the sidewall of the cone segment 102 into petal-shaped snap fingers. Thus, the elastic claw can be expanded by screwing in the conical head 201, and can be retracted by screwing out the conical head 201.

Optionally, the slits 1022 are four and are spaced apart circumferentially of the cone segment 102. That is, the side wall is configured with four petal-shaped spring fingers so that the endotracheal tube can be evenly rounded. Of course, in other examples, three or another number of slits 1022 may be provided.

According to the utility model discloses an in some embodiments, the surface of straight section of thick bamboo 101 is equipped with the non-skid projections 1011. The anti-slip protrusions 1011 are convenient for medical staff to hold the sleeve body 100 tightly, and ensure that the trachea cannula dilator is used stably and reliably. Of course, in other examples, anti-slip rings may be provided. The anti-slip protrusion 1011 is arranged at an end of the straight cylinder section 101 remote from the cone section 102.

According to some embodiments of the present invention, the length of the handle 202 is greater than the diameter of the straight section 101. Therefore, when the medical staff slides, the handle 202 can be clamped at the end of the straight cylinder section 101, and the whole driving rod 200 is prevented from entering the sleeve body 100.

According to some embodiments of the present invention, the driving rod 200 is hollow inside to form a gas channel 203, one end of the gas channel 203 is suitable for external oxygen, and the other end is connected to the endotracheal tube. Therefore, in the process of the operation of opening the tracheal cannula, oxygen can be supplied to the lung of the patient, and the safety of the circle correcting operation of the tracheal cannula is ensured. The port of the gas channel 203 communicating with the endotracheal tube may be disposed at the tip of the conical head 201, or may be disposed at a position on the side wall of the driving rod 200 near the conical head 201.

According to the utility model discloses a trachea cannula struts ware, it can be that two nurses assist the operation when rectifying trachea cannula, wherein the tip of trachea cannula is handed by alone, and this trachea cannula struts ware is operated to another person. Or a nurse can operate the tracheal intubation independently, at this time, a thumb sleeve can be arranged on the sleeve body 100, the thumb sleeve is sleeved on the thumb of the hand holding the tracheal intubation, and the other hand operates the driving rod 200 to perform the correction and circle correction of the tracheal intubation.
