Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to an airbag device for rigid bronchoscopes. Background Technology

[0002] Rigid bronchoscopes, also known as rigid endoscopes, are commonly used medical devices in modern medicine and are crucial tools for interventional pulmonary treatments. However, with the development and widespread adoption of flexible fiber optic bronchoscopes, their use has significantly decreased. Flexible fiber optic bronchoscopes, also called flexible bronchoscopes, utilize a beam guide composed of tens of thousands of highly transparent glass or acrylic fibers drawn vertically into very fine strands. While flexible fiber optic bronchoscopes have a smaller diameter, are more flexible to adapt to the human trachea, and offer a better field of vision compared to rigid bronchoscopes, rigid endoscopes still possess advantages that fiber optic bronchoscopes cannot replace. For example, while fiber optic bronchoscopes occupy a certain amount of airway space during operation and generally do not cause ventilation dysfunction in healthy adults, they can affect ventilation and even threaten the lives of children or those with airway stenosis. Rigid endoscopes maintain airway patency and have side ports at the operating end for connection to a ventilator; therefore, they are also called "ventilation bronchoscopes." Rigid bronchoscopes can also serve as interventional pathways, allowing fiber optic bronchoscopes to enter.

[0003] Patent CN202120896462.1 discloses an airbag device for a rigid bronchoscope, including a rigid bronchoscope body. The interior of the rigid bronchoscope body has a gas channel and an opening at the upper end. The lower side wall of the rigid bronchoscope body has two sets of air holes and one set of inflation ports. An airbag collar is fitted at the inflation port. The airbag collar includes a main airbag in the middle and reinforcing collars symmetrically arranged at both ends of the main airbag. The inner wall of the main airbag has an air inlet and an air guide tube connected to the outer side. The air inlet corresponds to the inflation port. The outer end of the air guide tube is located on one side of the opening. A through-hole is opened on one side of the opening. The air guide tube is inserted into the through-hole and its outer end is connected to a compression airbag.

[0004] In the aforementioned patent, the cuff ring is fixedly embedded in the rigid bronchoscope body, and its position cannot be adjusted, thus failing to meet the needs of different patients with different tracheal conditions. Utility Model Content

[0034] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] like Figure 1-3As shown, a cuff 3 device for a rigid bronchoscope includes a bronchoscope body 1, a moving tube 2, a cuff 3, a ventilation tube 4, an inflator 5, and a locking device 6. The bronchoscope body 1 has a gas channel 11 formed inside and an opening 12 at its upper end. Air holes are evenly distributed on the lower sidewall of the bronchoscope body 1. The moving tube 2 is sleeved on the outside of the bronchoscope body 1 and can slide relative to the outer wall of the bronchoscope body 1. The cuff 3 is sleeved and fixed on the outer wall of the moving tube 2. One end of the ventilation tube 4 is connected to the cuff 3, and the other end is connected to the inflator 5. The inflator 5 is used to inject gas into the cuff 3 and can be a press-type balloon. The press-type balloon has an air inlet and a one-way valve at the air inlet. The locking device 6 cooperates with the moving tube 2 to restrict the movement of the moving tube 2. The cuff 3 device allows for flexible adjustment of its position through the moving tube 2 sleeved on the bronchoscope body 1. The movable tube 2 can slide along the outer wall of the bronchoscope body 1, and the cuff 3 is fixed to the outer wall of the movable tube 2, communicating with the inflation device 5 (such as the compression balloon) through the ventilation tube 4. The locking device 6 is used to fix the position of the movable tube 2 to prevent it from sliding accidentally, so the position of the cuff 3 is adjustable to adapt to different patients' tracheal diameters and narrowing sites, solving the problem that traditional fixed cuff 3 cannot be adapted, and improving surgical safety and operational flexibility.

[0036] Specifically, the locking component 6 includes a thread 61, a sleeve 62, and an elastic pressure plate 63. The thread 61 is fixed to the end of the outer wall of the moving tube 2; the sleeve 62 is screwed onto the thread 61; the elastic pressure plate 63 is evenly fixed to the end of the moving tube 2. One side of the elastic pressure plate 63 can contact the inner wall of the sleeve 62, and the other side can contact the outer wall of the bronchoscope body 1. The locking component 6 is composed of the thread 61, the sleeve 62, and the elastic pressure plate 63 on the outer wall of the moving tube 2. When the sleeve 62 is rotated, the thread 61 drives the sleeve 62 to move axially along the moving tube 2, pushing the elastic pressure plate 63 to press against the inner wall of the sleeve 62 on one side and the outer wall of the bronchoscope body 1 on the other side. The moving tube 2 is fixed by friction. The bidirectional contact design of the elastic pressure plate 63 enhances the stability of locking, prevents the balloon 3 from shifting during the operation, and ensures the accuracy of operation. The inner wall of the sleeve 62 is provided with an arc-shaped curved surface 621. The arc-shaped curved surface of the inner wall of the sleeve 62 forms a smooth transition with the contact surface of the elastic pressure plate 63, making the locking operation less strenuous and improving the user experience. The elastic pressure plate 63 is curved, which reduces the contact between the elastic pressure plate 63 and the outer wall of the bronchoscope body when not locked.

[0037] In other embodiments, the elastic pressure plate 63 is fixedly provided with a plurality of elastic protrusions 64. The elastic protrusions 64 increase the micro-friction of the contact surface, further improving the locking reliability, especially suitable for smooth or wet bronchoscope surfaces, to prevent accidental loosening.

[0038] In other embodiments, the outer wall of the sleeve 62 is provided with a plurality of anti-slip protrusions 65; the anti-slip design makes it easy for medical staff to rotate the sleeve 62, and can be operated stably even when wearing gloves or with wet hands, thereby improving surgical efficiency and safety.

[0039] In other embodiments, a limiting protrusion 66 is fixedly provided on the outer wall of the bronchoscope body 1, and a sliding groove is provided on the inner wall of the moving tube 2 to cooperate with the limiting protrusion 66. The limiting protrusion 66 can slide relative to the sliding groove to prevent the moving tube 2 from rotating when the sleeve 62 is rotated.

[0040] In other embodiments, a fixing member 67 is provided on the outer wall of the movable tube 2, and the fixing member 67 is provided with a through hole for the ventilation tube 4 to pass through; the ventilation tube 4 is fixed in position to avoid the tube from twisting or falling off due to traction or movement during the operation, to ensure smooth air passage and improve the reliability of the device.

[0041] In other embodiments, the press-down balloon is provided with an exhaust port 68, and the exhaust port 68 is provided with a switch 69, which is an elastic plunger; the press-down balloon is provided with an exhaust port 68, and the opening and closing of the exhaust port 68 can be controlled by the switch 69 to quickly release the gas in the airbag 3.

[0042] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
