Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a medical Y-shaped airway stent. Background Art

[0002] A tracheal stent is a medical device used to support and maintain the patency of the trachea, usually used in the treatment of tracheal stenosis, bronchial stenosis or other airway diseases. As an important medical device, the tracheal stent plays a key role in solving airway diseases and maintaining airway function, providing effective treatment and care options for patients.

[0003] Traditional tracheal stents are composed of multiple straight stents. The main part of the tube stent is usually made of metal alloy or plastic, with strength and corrosion resistance, suitable for long-term placement in the body. The shape and size of the main stent will depend on the specific situation and treatment needs of the patient, and different lengths and diameters may be available for selection.

[0004] However, due to the special human structure at the tracheal trifurcation, in case of lesions, generally one straight stent cannot achieve the treatment effect, and three straight stents are required for combined treatment. Multiple straight stents will lead to multiple surgeries, and the straight stents are prone to slip and shift at the tracheal trifurcation, reducing the practicability of this stent. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a medical Y-shaped airway stent, aiming to improve the problem that the traditional tracheal stent is prone to slip and shift at the tracheal trifurcation, reducing the practicability of this stent.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a medical Y-shaped airway stent, including a Y-shaped stent body, the bottom of the Y-shaped stent body is fixedly connected with a left bronchial stent, the bottom of the Y-shaped stent body is fixedly connected with a right bronchial stent, a hollow opening is arranged inside the right bronchial stent, rounded corners are arranged at the bottoms of both the left bronchial stent and the right bronchial stent, a plurality of ventilation holes are arranged inside the Y-shaped stent body, and a connecting component is arranged inside the left bronchial stent for connecting the left bronchial stent.

[0007] Further, the connecting component includes a first connecting piece, and the first connecting piece is fixedly connected inside the left bronchial stent.

[0008] Further, an extension tube is arranged at the bottom of the left bronchial stent, and a second connecting piece is fixedly connected inside the extension tube.

[0009] Further, a plurality of first fixing pieces are fixedly connected to the side wall of the first connecting piece, and the first fixing pieces are symmetrical to each other.

[0010] Furthermore, a plurality of second fixing members are fixedly connected to the two side walls of the connecting member, and the second fixing members are symmetric with each other.

[0011] Furthermore, clamping grooves are formed inside both the first fixing member and the second fixing member.

[0012] Furthermore, a plurality of clamping blocks are fixedly connected to the side walls of both the first connecting member and the second connecting member, and the clamping blocks are slidably connected inside the clamping grooves.

[0013] Furthermore, hollow holes are formed inside both the first connecting member and the second connecting member.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, first, the Y-shaped integrated tracheal stent is used to solve the problems of multiple surgeries, slippage and displacement of the straight stent. An open hole is formed inside the right bronchial stent, avoiding the problem that the right bronchial stent is too short to treat the lesions at the secondary branch of the right bronchus and too long to block the secondary branch of the right bronchus.

[0016] 2. In the utility model, the rotation of the second connecting member drives a plurality of clamping blocks on its side wall and the second fixing member to displace synchronously. Since clamping grooves are formed inside both the second fixing member and the first fixing member and the clamping blocks can slide therein, the mutual connection between the left bronchial stent and the extension tube is finally achieved, so that the extension tube can be conveniently disassembled and assembled, and the length of the left bronchial stent can be adjusted, so as to ensure that the stent is stably inserted and maintains the correct position.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Refer to Figure 1 - Figure 2 As an embodiment provided by the present invention: A medical Y-shaped airway stent includes a Y-shaped stent body 1. A left bronchial stent 3 is fixedly connected to the bottom of the Y-shaped stent body 1. A right bronchial stent 2 is fixedly connected to the bottom of the Y-shaped stent body 1. A hollow opening 4 is formed inside the right bronchial stent 2. Rounded corners 6 are formed at the bottoms of both the left bronchial stent 3 and the right bronchial stent 2. A plurality of ventilation holes 5 are formed inside the Y-shaped stent body 1. A connection assembly is arranged inside the left bronchial stent 3, and the connection assembly is used to connect the left bronchial stent 3.

[0025] Specifically, in this stent, the Y-shaped stent body 1 is the core structure of the stent, and its shape is similar to the letter Y. This design enables the stent to enter the oral cavity and trachea simultaneously, effectively maintaining the patency of the airway. The Y-shaped integrated tracheal stent solves the problems of multiple surgeries, slippage, and displacement that may be caused by traditional straight stents. A hollow opening 4 is formed inside the right bronchial stent 2. This design precisely avoids two common problems: the stent being too short to cover the lesions at the secondary branches of the right bronchus, and the stent being too long may cause blockage of the secondary branches of the right bronchus. The rounded corner 6 design of the stent reduces the risk of damage to the oral and pharyngeal tissues during insertion, thereby improving the comfort and safety of the patient. The ventilation holes 5 not only help ensure the patency of the airway but also allow medical staff to aspirate oral secretions or perform other treatment operations.

[0026] Refer to Figure 3 and Figure 4, the connecting component includes a first connecting piece 7, the first connecting piece 7 is fixedly connected inside the left bronchial stent 3, an extension tube 14 is arranged at the bottom of the left bronchial stent 3, a second connecting piece 8 is fixedly connected inside the extension tube 14, a plurality of first fixing pieces 9 are fixedly connected to the side wall of the first connecting piece 7, the first fixing pieces 9 are symmetric with each other, a plurality of second fixing pieces 10 are fixedly connected to the side wall of the second connecting piece 8, the second fixing pieces 10 are symmetric with each other, clamping grooves 11 are formed inside both the first fixing pieces 9 and the second fixing pieces 10, and a plurality of clamping blocks 12 are fixedly connected to the side walls of both the first connecting piece 7 and the second connecting piece 8, the clamping blocks 12 are slidably connected inside the clamping grooves 11, and hollow holes 13 are formed inside both the first connecting piece 7 and the second connecting piece 8.

[0027] Specifically, align the extension tube 14 with the left bronchial stent 3, and then rotate the extension tube 14. During this process, the second connecting piece 8 inside the extension tube 14 will rotate accordingly, and the rotation of the second connecting piece 8 drives a plurality of clamping blocks 12 on the side wall and the second fixing pieces 10 to move synchronously. Here, both the connecting piece and the fixing piece are made of silicone. Since clamping grooves 11 are formed inside both the second fixing pieces 10 and the first fixing pieces 9, and the clamping blocks 12 can slide therein, during the connection process, the second fixing pieces 10 on the side wall of the second connecting piece 8 will be engaged with the clamping blocks 12 on the side wall of the first connecting piece 7, and at the same time, the first fixing pieces 9 on the side wall of the first connecting piece 7 are engaged with the second fixing pieces 10 on the side wall of the second connecting piece 8. This design enables the left bronchial stent 3 and the extension tube 14 to be connected to each other, thereby realizing the convenient disassembly, assembly and length adjustment of the extension tube 14. Such a mechanism ensures that the stent can be stably inserted and maintain the correct position, providing safe and effective treatment for patients.

[0028] Working principle: In this stent, the Y-shaped stent body 1 is the main structure, and its shape is similar to the letter Y. The Y-shaped design enables the stent to enter the oral cavity and trachea simultaneously to maintain the patency of the airway. The Y-shaped one-piece tracheal stent can solve the problems of multiple surgeries, slippage, and displacement of straight stents. The right bronchial stent 2 is internally provided with a hollow opening 4, which avoids the problem that the right bronchial stent 2 is too short to treat the lesions at the second branch of the right bronchus and too long to block the second branch of the right bronchus. The rounded corners 6 reduce the damage to the oral and pharyngeal tissues during insertion. The ventilation holes 5 contribute to ventilation and allow the aspiration of secretions in the oral cavity or other therapeutic operations. If it is necessary to change the length of the left bronchial stent 3 for extension, align the extension tube 14 with the left bronchial stent 3 and rotate it. At this time, the connecting piece II 8 inside the extension tube 14 rotates accordingly. The rotation of the connecting piece II 8 drives the multiple clamping blocks 12 on its side wall and the fixing piece II 10 to displace synchronously. Since the fixing piece II 10 and the fixing piece I 9 are both internally provided with clamping grooves 11 and the clamping blocks 12 can slide therein, the fixing piece II 10 on the side wall of the connecting piece II 8 is engaged with the clamping block 12 on the side wall of the connecting piece I 7, and the fixing piece I 9 on the side wall of the connecting piece I 7 is engaged with the fixing piece II 10 on the side wall of the connecting piece II 8, thereby achieving the mutual connection between the left bronchial stent 3 and the extension tube 14, realizing the convenient disassembly and assembly of the extension tube 14, and achieving the effect of adjustable length of the left bronchial stent 3 to ensure stable insertion of the stent and maintain the correct position.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
