Description

Technical Field

[0001] The present application relates to the field of medical devices, and more particularly, to a retrograde puncture positioning tracheotomy cannula for airway atresia. Background Art

[0002] 1. Briefly introduce the background knowledge of the present patent technology;

[0003] Benign central airway stenosis (BCAS) refers to airway stenosis caused by various benign lesions in the trachea, left and right main bronchi, and right intermediate bronchus, which can lead to varying degrees of dyspnea or even asphyxia and death in patients clinically. The most common treatment methods are endotracheal intubation and tracheotomy. Among them, airway stenosis caused by intubation mostly involves the subglottic region, and even subglottic stenosis of grade IV (Cotton-Myer IV classification) in this region of the airway (also known as airway atresia) may occur.

[0004] For current patients with airway atresia, a rigid endoscope is inserted into the glottis, and a high-frequency electric knife is used to gradually ablate and open the airway towards the distal end at the central position of the airway atresia. At the same time, retrograde dissection is performed from the tracheotomy opening, and appropriate dilation is performed after the airway is reopened. However, due to the lack of anatomical landmarks during airway surgery, dilation is blind, and the operation can only be carried out based on experience, which is prone to positioning failure, resulting in the deep puncture needle being inserted outside the airway wall and repositioning being required, thereby increasing the operation duration and the chance of infection. Moreover, laryngeal edema may occur after repeated entry and exit of the glottis, requiring the operation to be postponed. Summary of the Utility Model

[0005] The main purpose of the present application is to provide a retrograde puncture positioning tracheotomy cannula for airway atresia, including: a tracheotomy cannula body; a fixed flank, which is annularly arranged at the opening of the tracheotomy cannula body and is perpendicular to the opening of the tracheotomy cannula; at least one positioning hole, which is arranged on the side wall of the tracheotomy cannula body; at least one positioning mark, which is arranged on the at least one positioning hole; a fixed groove, which is arranged at the opening.

[0006] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, the positioning holes are distributed along the axial direction of the tracheotomy cannula body.

[0007] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, each positioning hole is provided with one positioning mark.

[0008] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, the positioning mark is a metal ring.

[0009] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, the positioning mark is embedded inside the inner side of the positioning hole.

[0010] The above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia has 12 positioning holes.

[0011] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, the number of the positioning marks is 3, and they are respectively arranged at the 1st, 5th, and 9th positioning holes.

[0012] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, the fixing groove is perpendicular to the fixing wing.

[0013] For the above-mentioned retrograde puncture positioning tracheotomy cannula for airway atresia, the fixing groove is circular.

[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] By pre-drilling positioning holes in the tracheotomy cannula and providing positioning marks at the positioning holes, the tracheotomy cannula is first inserted into the patient's airway before the operation, and then the positioning marks are developed (for example, the positioning marks can be made of metal, and then devices such as X-ray or CT are used to irradiate the positions of the positioning marks in the patient's airway). Then, according to the relative positions of the positioning marks and the airway atresia to be punctured in the development, it is determined from which positioning hole the deep puncture needle should be punctured. Since the curvature of the cannula is fixed, the positions and angles of each positioning hole are fixed, and the positions and angles of the fixing groove are fixed, the angles and curvatures of the deep puncture needle from the fixing groove to each fixing hole are respectively fixed. Therefore, finally, only a deep puncture needle with a matching angle and curvature needs to pass through the fixing groove and the determined positioning hole to achieve the purpose of accurately puncturing the airway atresia, without relying on the doctor's experience, improving the accuracy and success rate, and shortening the operation time.

[0024] Embodiment 1

[0025] Please refer to Figures 1-4 .

[0026] The retrograde puncture positioning tracheotomy cannula for airway atresia includes: a tracheotomy cannula body 1, fixed side wings 2, at least one positioning hole 3, at least one positioning mark, and a fixed groove 4. Among them, the fixed side wings 2 are looped around the opening 5 of the tracheotomy cannula body 1 and are perpendicular to the opening 5 of the tracheotomy cannula; the positioning holes 3 are provided on the side wall of the tracheotomy cannula body 1; the positioning marks (not shown in the figure) are provided on the at least one positioning hole 3; the fixed groove 4 is provided on the opening 5.

[0027] During the operation, positioning holes are pre - drilled in the tracheotomy cannula, and positioning marks are provided at the positioning holes. In this way, the tracheotomy cannula is inserted into the patient's airway before the operation, and then the positioning marks are developed (for example, the positioning marks can be made of metal, and then devices such as X - ray or CT are used to irradiate the position of the positioning marks in the patient's airway). Then, according to the relative position between the positioning marks in the development and the airway atresia to be punctured, it is determined from which positioning hole the deep puncture needle 6 should be passed through. Since the curvature of the cannula is fixed, the positions and angles of each positioning hole are fixed, and the positions and angles of the fixing grooves are fixed, the angles and curvatures of the deep puncture needle from the fixing groove to each fixing hole are respectively fixed. Therefore, finally, only a deep puncture needle with a matching angle and curvature needs to pass through the fixing groove and the determined positioning hole to achieve the purpose of accurately puncturing the airway atresia, without relying on the doctor's experience, improving the accuracy and success rate, and shortening the operation time.

[0028] In this embodiment, the positioning holes 3 are distributed along the axial direction of the tracheotomy cannula body 1. This is done to better perform surgical positioning. However, it is not limited to this. Those skilled in the art can change the distribution and arrangement of the positioning holes according to the actual situation. For example, positioning holes are drilled on other side walls of the tracheotomy cannula body to simultaneously complete other operations, or for some patients with special airway directions, positioning holes need to be drilled on the side walls in multiple directions. These all fall within the scope claimed in this application.

[0029] Embodiment 2

[0030] In this application, the number of positioning marks is not limited. Because as long as there are positioning marks, regardless of the number, even if there is only one positioning mark, it will greatly improve the doctor's reference standard during the operation, thus greatly increasing the accuracy rate of the operation. However, in this embodiment, each positioning hole 3 is provided with one positioning mark. This positioning mark can be set inside the positioning hole to form a circular ring, or can be set inside or outside the positioning hole, or other shapes are also acceptable, all of which fall within the scope claimed in this application.

[0031] Embodiment 2

[0032] In this embodiment, the number of positioning holes 3 is 12, and the number of positioning marks is 3. And the positioning marks are respectively located at the 1st, 5th, and 9th positioning holes. However, it is not limited to this. Those skilled in the art can change the number and spacing of the positioning holes according to actual needs, and can also change the number and setting positions of the positioning marks, all of which fall within the scope claimed in this application.

[0033] In this application, the material and the method of revealing the positioning identifier are not limited. Any known material that can be revealed by any means and method through the patient's body can be the material required by this application, and it is not necessarily limited to metals only.

[0034] In this embodiment, the fixing groove 4 is perpendicular to the plane where the fixing flank 2 is located and is provided on the fixing flank. Additionally, in this embodiment, the fixing groove 4 is circular, but this is not a limitation. Those skilled in the art can change the angle and position of the fixing groove 4 according to actual needs, as long as it can fix the arc and angle between the fixing groove and the positioning hole, and it all falls within the scope protected by this application.

[0035] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the protection scope of this application.
