Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a cleaning device for an airway stent. Background Technology

[0002] For patients with benign or malignant airway stenosis, a silicone stent needs to be placed in the airway to ensure normal ventilation. The silicone stent is used to expand the patient's airway and prevent it from becoming too narrow. However, for patients with excessive airway secretions, a large amount of sputum deposits may adhere to the inner wall of the stent after a period of time, making them difficult to clean.

[0003] Existing methods for cleaning the airway mainly involve removing the silicone stent from the patient's airway and manually cleaning it, or using a cryotherapy device to clean the secretions in the airway. The disadvantages are: cryotherapy is time-consuming and causes a lot of pain for the patient; and re-implanting the stent after it has been removed and cleaned presents technical difficulties and surgical risks, as well as high economic costs.

[0004] To address the problems of inconvenient, time-consuming, and labor-intensive cleaning of silicone stents in existing technologies, as well as their significant impact on patients, it is necessary to improve the structure of the airway stent cleaning device to solve the current technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an airway stent cleaning device that combines an electronic bronchoscope with a cell brush structure. The device inserts into the patient's airway through the forceps channel of the bronchoscope to clean the silicone stent. The entire cleaning process does not require removal of the silicone stent, making it convenient, quick, and with minimal impact on the patient.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a cleaning device for an airway support, comprising:

[0007] A bronchoscope, wherein the bronchoscope is provided with a forceps channel and a working channel, the forceps channel smoothly transitioning from the side wall of the bronchoscope and connecting to the working channel;

[0008] The protective sleeve is slidably inserted into the clamp channel and the working channel in sequence;

[0009] The guide wire is slidably threaded through the protective sleeve;

[0010] The brush head is fixedly connected to one end of the guide wire.

[0011] By adopting the above technical solution, under the guidance of the guide wire, the brush head is first stored in the protective sleeve, which can prevent the brush head from brushing foreign objects in the forceps channel and working channel into the patient's trachea or tracheal stent. Then, the bronchoscope is inserted into the patient's trachea, and the position of the tracheal stent is found according to the image of the bronchoscope lens. Then, the protective sleeve, guide wire and brush head are inserted together from the forceps channel and gradually inserted into the working channel until the very tip of the bronchoscope. The protective sleeve does not go out of the working channel. Finally, the guide wire is pushed to push the brush head out of the protective sleeve so that it contacts the tracheal stent, and cleaning can be performed. The lens of the bronchoscope can be manually controlled to move the brush head forward, backward or turn. The entire cleaning process does not require the removal of the silicone stent, which is convenient and quick and has little impact on the patient.

[0012] To better realize this utility model, the outer edge of the end of the protective sleeve that penetrates the clamp channel and the working channel has a rounded corner structure.

[0013] By adopting the above technical solution, the rounded protective sleeve tip makes smooth contact with the forceps channel and working channel, which not only protects the inner wall of the bronchoscope, but also prevents debris in the forceps channel and working channel from being brought into the patient's trachea or stent.

[0014] To better realize this utility model, the outer diameter of the protective sleeve is smaller than the diameter of the working channel.

[0015] By adopting the above technical solution, the working channel can be provided with space for the discharge of foreign objects.

[0016] To better realize this utility model, the outer diameter of the protective sleeve is adapted to the diameter of the clamp channel.

[0017] By adopting the above technical solution, the clamp channel is nearly sealed, which will not affect the negative pressure attraction of the negative pressure generator, and debris will not be discharged into the clamp channel.

[0018] To better realize this utility model, the working channel is connected to a negative pressure suction tube, and the negative pressure suction tube is connected to a negative pressure generator.

[0019] By adopting the above technical solution, negative pressure suction is used to draw out the cleaned debris.

[0020] To better realize this utility model, the guide wire is fixedly connected to an annular control handle away from the brush head.

[0021] By adopting the above technical solution, it is easy to control the movement of the guide wire and brush head within the protective sleeve.

[0022] To better realize this utility model, the brush head includes a central rod and bristles, the central rod is fixedly connected to the guide wire, and the surface of the central rod is fully covered with bristles.

[0023] By adopting the above technical solution, the surface of the central rod is fully covered with bristles to form a bristle brush head, which can be used to clean the tracheal stent under the guidance of the guide wire.

[0024] Beneficial effects:

[0025] This invention combines an electronic bronchoscope with a brush head. The brush head is inserted into the patient's airway through the forceps channel of the bronchoscope to clean the silicone stent. The entire cleaning process does not require the removal of the silicone stent, making it convenient, quick, and with minimal impact on the patient. Under the imaging of the lens at the front end of the electronic bronchoscope, the lens direction can be manually controlled, making it easy to move the brush head forward, backward, or turn, thus ensuring the cleaning effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] like Figure 1 - Figure 3 As shown, a cleaning device for an airway stent includes:

[0033] The bronchoscope 1 is an electronic bronchoscope commonly used in the prior art, such as PENTAX FB-15P, Olympus BF-P30, etc. It is equipped with a light source system, imaging system, etc., which will not be described in detail here. The bronchoscope 1 has a clamp channel 11 and a working channel 12 inside. The clamp channel 11 smoothly transitions from the side wall of the bronchoscope 1 and connects to the working channel 12.

[0034] The protective sleeve 2 is gradually inserted into the working channel 12 from the forceps channel 11. The brush head 4 is first stored in the protective sleeve 2 and then inserted into the working channel 12 from the forceps channel 11. This can prevent the brush head 4 from brushing foreign objects in the forceps channel 11 and the working channel 12 into the patient's trachea or tracheal stent.

[0035] The guide wire 3 slides through the inside of the protective sleeve 2 and is usually made of materials such as stainless steel or nickel-titanium alloy. These materials have good flexibility, bending resistance and biocompatibility;

[0036] The brush head 4 is fixedly connected to one end of the guide wire 3. Guided by the guide wire 3, the brush head 4 is first housed in the protective sleeve 2, and then, together with the protective sleeve 2, it is inserted from the clamp channel 11 into the working channel 12 until it reaches the front end of the bronchoscope 1. Then, the brush head 4 is inserted from the protective sleeve 2 into the support for brushing. The lens of the bronchoscope 1 can be manually controlled to adjust the lens direction, making it easy to move the brush head 4 forward, backward, or in a different direction.

[0037] The working principle of this utility model can be summarized as follows:

[0038] Before cleaning, disinfect components such as the bronchoscope 1, protective sleeve 2, guide wire 3, and brush head 4. Insert the other end of the guide wire 3 into the protective sleeve 2 until the brush head 4 is close to the protective sleeve 2. Then, under the pull and guidance of the guide wire 3, the brush head 4 is first stored in the protective sleeve 2. Alternatively, the guide wire 3 can be inserted into the protective sleeve 2 first, then the brush head 4 can be connected, and under the pull and guidance of the guide wire 3, the brush head 4 can be stored in the protective sleeve 2.

[0039] Subsequently, the bronchoscope 1 is inserted into the patient's trachea. Based on the image captured by the lens of the bronchoscope 1, the position of the tracheal stent is located. Then, the protective sleeve 2, guide wire 3, and brush head 4 are inserted together from the clamp channel 11 and gradually inserted into the working channel 12 until the very tip of the bronchoscope 1. The protective sleeve 2 does not protrude out of the working channel 12.

[0040] Finally, push the guide wire 3 to push the brush head 4 out of the protective sleeve 2 so that it contacts the tracheal support, and cleaning can be performed. The lens of the bronchoscope 1 can be manually controlled to move the brush head 4 forward, backward or turn.

[0041] Preferably, the outer edge of the end of the protective sleeve 2 that penetrates the forceps channel 11 and the working channel 12 has a rounded corner structure. When the protective sleeve 2 passes through the forceps channel 11 and the working channel 12, the rounded corner end of the protective sleeve 2 makes smooth contact with the forceps channel 11 and the working channel 12, which not only protects the inner wall of the bronchoscope 1, but also prevents debris in the forceps channel 11 and the working channel 12 from being brought into the patient's trachea or stent.

[0042] Preferably, the working channel 12 is connected to a negative pressure suction tube 5, which in turn is connected to a negative pressure generator 6. The outer diameter of the protective sleeve 2 is smaller than the diameter of the working channel 12, and the outer diameter of the protective sleeve 2 is adapted to the diameter of the clamp channel 11. After the brush head 4 cleans the sputum and other foreign objects in the stent, under the action of the negative pressure generator 6, the foreign objects are sucked in from the very tip of the bronchoscope 1 and gradually discharged through the gap between the protective sleeve 2 and the working channel 12. Since the outer diameter of the protective sleeve 2 is adapted to the diameter of the clamp channel 11, the clamp channel 11 is nearly sealed, which will not affect the negative pressure suction of the negative pressure generator 6, and the debris will not be discharged into the clamp channel 11. By using the brush head properly during the cleaning process, after brushing off some sputum and debris, suctioning it out first, and then continuing to brush off other sputum and debris, this can be avoided. This gradual approach can ensure that sputum and debris are fully cleaned and will not fall into the trachea or tracheal stent.

[0043] Preferably, the guide wire 3 is fixedly connected to an annular control handle located away from the brush head 4. This facilitates the insertion or removal of the brush head 4 and guide wire 3 into the protective sleeve 2.

[0044] Preferably, the brush head 4 adopts a cellular brush structure, including a central rod 41 and bristles 42. The central rod 41 is fixedly connected to the guide wire 3, and the surface of the central rod 41 is fully covered with bristles 42. The bristles 42 fully cover the surface of the central rod 41, forming a bristle brush head, which can be used to brush the tracheal stent under the guidance of the guide wire 3.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
