Description

Technical Field

[0001] This utility model relates to the field of fiberoptic bronchoscope technology, specifically to a fixation device for fiberoptic bronchoscope intubation. Background Technology

[0002] A fiberoptic bronchoscope is a flexible tube consisting of a light source and a display system that uses optical fiber technology. It is used for the observation, biopsy sampling, cytological and bacteriological examination of lesions in the lobes, segments and subsegments of the lungs. When used with a television system, it can be used for photography, teaching and dynamic recording.

[0003] When using a traditional fiberoptic bronchoscope for intubation via the oral approach, the tip has virtually no room for movement due to soft tissue compression, affecting the physician's observation of the bronchoscope and increasing the difficulty of observation and intubation. This can be addressed by placing a cannula over the outside of the bronchoscope to increase the scope of movement. The cannula needs to be secured to ensure ease of operation. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] This embodiment relates to a fixation device for fiberoptic bronchoscope cannulation.

[0029] A fiberoptic bronchoscope includes: an operating section, a body, and a tip; the lens of the fiberoptic bronchoscope is located at the tip.

[0030] Specifically, such as Figure 1-4 As shown, the fixation device 1 is a hollow column with a hollow channel 7 inside. One end of the fixation device 1 is a cannula fixing part 2, used to connect and fix the cannula to the fixation device 1, thus connecting the internal space of the cannula to the hollow channel 7. The bronchoscope's body and tip can enter the internal space of the cannula through the hollow channel 7 of the fixation device 1. One end of the fixation device 1 is equipped with a clamping component, which clamps and fixes the bronchoscope body within the hollow channel 7, thus connecting the fixation device 1 and the bronchoscope. By connecting the bronchoscope and the cannula through the fixation device 1, the cannula is fixed, ensuring it always fits over the outer side of the bronchoscope's tip. The cannula can spread the soft tissue around the tip, providing some space for movement, facilitating adjustment of the lens angle, and improving observation of the surrounding area, thereby enhancing intubation and diagnostic effectiveness.

[0031] In this embodiment, the intubation tube fixing part 2 is a fixing groove disposed around the hollow channel 7. The fixing groove extends along the direction of the hollow channel 7, and the intubation tube can be inserted and snapped into the fixing groove to achieve the connection and fixation of the intubation tube and the fixing device 1. This allows the hollow channel 7 to communicate with the internal space of the intubation tube, facilitating the entry of the fiberoptic bronchoscope body and tip into the internal space of the intubation tube. Preferably, the fixing groove is annular, and the outer diameter and inner diameter of the fixing groove correspond to the size of the intubation tube to achieve better fixation of the intubation tube. Of course, in other embodiments, the intubation tube fixing part 2 can also be configured as an annular fixing step surface, with the outer diameter of the annular fixing step surface corresponding to the inner diameter of the intubation tube. The intubation tube can be fitted onto the annular fixing step surface to achieve the connection and fixation between the intubation tube and the fixing device 1.

[0032] In this embodiment, the end of the fixing device 1 near the insertion tube fixing part 2 is larger than the end of the fixing device 1 near the clamping component, which makes it easier for the user to distinguish the usage direction of the fixing device 1, and also facilitates the installation and operation of the clamping component.

[0033] As a preferred embodiment, the clamping assembly includes two sets of clamping members 3, which are respectively arranged on both sides of the hollow channel 7 to clamp the endoscope of the fiberoptic bronchoscope in the middle of the hollow channel 7, ensuring its clamping stability, while avoiding interference from the inner wall of the hollow channel 7 and the inner wall of the intubation tube, which would affect the movement and observation of the tip of the fiberoptic bronchoscope.

[0034] In this embodiment, a mounting hole 4 for mounting the clamping member 3 is provided at one end of the fixing device 1 near the clamping assembly. The clamping member 3 includes a mounting post 5 that mates with the mounting hole 4, and a clamping part 6 connected to the inner side of the mounting post 5. The clamping member 3 is installed inside the hollow channel 7 through the mating of the mounting post 5 and the mounting hole 4. The clamping part 6 is used to clamp the scope body inside the hollow channel 7 to achieve the connection and fixation between the fiberoptic bronchoscope and the fixing device 1.

[0035] As a preferred embodiment, a damping element is provided between the mounting post 5 and the mounting hole 4. The mounting post 5 is damped and slidably disposed within the mounting hole 4. Sufficient force is required to slide the mounting post 5 and change the position of the clamping part 6, thereby achieving the locking of the fiberoptic bronchoscope. The user can push or pull the mounting post 5 to bring the clamping parts 6 of the two clamping parts 3 closer or further apart, thereby clamping or unlocking the fiberoptic bronchoscope.

[0036] In some other embodiments, the mounting hole 4 is configured as a threaded hole, and the mounting post 5 is configured as a threaded post corresponding to the mounting hole 4. The clamping member can be adjusted and locked through the cooperation of the threaded hole and the threaded post, so as to achieve a good clamping effect.

[0037] In some other embodiments, an elastic element is provided on the periphery of the mounting post 5, between the mounting hole 4 and the clamping part 6, so as to push the clamping part 6 towards the center of the hollow channel 7 to clamp the mirror body, thereby realizing the function of automatic clamping. The elastic element can be compressed by pulling the mounting post 5 to release the clamping part 3.

[0038] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
