Description

Technical Field

[0001] The utility model belongs to the technical field of pediatrics, and specifically relates to a pediatric bronchoscopic catheter device. Background Art

[0002] A bronchoscope is a medical device that is inserted into the patient's lower respiratory tract through the mouth or nose and is used for observation, biopsy and sampling of lesions in the lobes, segments and subsegments of the bronchi. In order to make it easier for the bronchoscope tube to pass through the mouth and into the lung tissue during bronchoscopy, a catheter device is required for auxiliary examination.

[0003] For example, Chinese patent publication number CN211933992U discloses a pediatric bronchoscopic catheter device. The device includes a protrusion with a mirror tube fixedly connected to the top of the protrusion, a handle fixedly connected to the bottom of the protrusion, a protective tube fixedly connected to the bottom of the handle, a catheter mounted inside the protective tube, and a peeling mechanism fixedly mounted on the outside of the protective tube. The device secures the protective tube to the outside of the catheter, which then passes through a guide block and other structures to be inserted into the patient's body for examination.

[0004] As described in the prior art of the above-mentioned device, although it has a guiding effect on the bronchoscope, when the bronchoscope is inserted into the patient's body and reaches the lesion, the doctor needs to inject physiological saline into the lesion through the bronchoscope to better image it, or perform biopsy sampling at the lesion through the bronchoscope. The above operations require the doctor to hold the bronchoscope to maintain the length of the mirror tube inserted into the human body. The existing equipment is not convenient for positioning the length of the mirror tube inserted into the human body, which easily causes the doctor to consume a lot of physical energy during the long operation.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places in this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Furthermore, this utility is described in detail with reference to schematic diagrams. For ease of explanation, the cross-sectional views of the device structures will be partially enlarged and not to scale when describing the embodiments of this utility. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of this utility. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0027] Please see the attached Figure 1 and Figure 2 As shown, the present invention provides a pediatric bronchoscopic catheter device, including a lip plate 1 that contacts the patient's lips, a guide tube 2 installed on the side of the lip plate 1 away from the patient's lips, a notch formed on the side of the guide tube 2, a positioning assembly 3 provided on the side of the notch of the guide tube 2, and a guide tube 2 4 provided on the side of the lip plate 1 that contacts the patient; wherein the positioning assembly 3 includes a clamping plate 31, a connecting rod 32 connected to the outer side of the clamping plate 31, the connecting rod 32 being connected to the clamping guide cylinder 34, and a spring 35 being sleeved on the connecting rod 32, one end of the spring 35 pressing against the clamping guide cylinder 34, and the other end of the spring 35 pressing against the clamping plate 31;

[0028] In this embodiment, when performing a bronchoscopic examination on a patient, the lip plate 1 is first placed against the patient's lips, and the guide tube 2 4 is placed in the patient's oral cavity. Then, the mirror tube 6 of the bronchoscope is inserted from one end of the guide tube 1 2 and then enters the patient's oral cavity through the guide tube 2 4. The bronchoscope then travels along the patient's bronchus to the lesion for examination. When sampling or injection of saline for imaging examination is required, the length of the mirror tube 6 extending into the human body needs to be kept constant. The clamping plate 31 of the positioning assembly 3 can be released to move closer to the guide tube 1 2, thereby clamping the mirror tube 6. This keeps the length of the mirror tube 6 in the human body constant, making it easier for medical staff to perform examinations or sampling.

[0029] Through the guide tube 1 2 and the guide tube 2 4, the mirror tube 6 of the bronchoscope can be conveniently extended from the patient's mouth into the patient's body to reach the lesion for inspection and sampling. In addition, during the inspection process, in order to ensure that the length of the mirror tube 6 extended into the patient's body remains unchanged, on the one hand, it can be convenient to perform sampling or inspection through the mirror tube 6, and on the other hand, it can reduce the excessive physical exertion of medical staff due to the need to maintain a certain posture for a long time due to the need to maintain the length of the mirror tube 6 extended into the human body unchanged. During the inspection or sampling process, the length of the mirror tube 6 extended into the human body can be maintained by clamping the mirror tube 6 by releasing the clamping plate 31 of the positioning component 3, thereby facilitating inspection and sampling.

[0030] See Figure 2As shown, a rubber strip 11 is attached to the edge of one side of the lip plate 1 and the patient's lip, and a tooth chamber baffle 41 is also installed on the side where the lip plate 1 is installed on the guide tube 2 4, and the tooth chamber baffle 41 is respectively arranged on the upper and lower sides of the guide tube 2 4;

[0031] A rubber strip 11 is provided on the side of the lip plate 1 that contacts the patient's lips, which can act as a buffer against contact with the patient's lips and prevent the lip plate 1 from causing injury to the patient's skin;

[0032] When performing a bronchoscopic examination through the patient's mouth, the upper and lower jaws will unconsciously bite together due to human physiological reactions. In order to avoid the problem that the patient bites the mirror tube 6 of the bronchoscope and cannot be inserted into the patient's body, tooth chamber baffles 41 are provided on the upper and lower sides of the guide tube 2 4, so that the patient's upper and lower jaws bite on the tooth chamber baffles 41 on the upper and lower sides respectively, so that the patient's mouth is open for easy examination.

[0033] The two ends of the lip plate 1 are connected with straps 5 respectively, and the two straps 5 are connected by Velcro, and the straps 5 are elastic structures;

[0034] The lip plate 1 placed on the patient's lips can be bound by the strap 5, and then the entire device can be fixed in the patient's mouth to prevent dislocation. When in use, the strap 5 is wrapped around the back of the patient's head and bound with Velcro. The strap 5 is elastic and can be stretched according to the different head circumferences of each patient.

[0035] See also Figure 3 and Figure 4 As shown, the clamping plate 31 and the connecting rod 32 are rotatably connected, the clamping guide cylinder 34 is fixedly connected to the lip plate 1, a pull ring 33 is provided at the end of the connecting rod 32 away from the clamping plate 31, and a bayonet 321 is provided in the middle section of the connecting rod 32; the clamping guide cylinder 34 has a clamping groove 341 on the left and right sides, and a clamping guide groove 342 on the upper and lower sides. A rubber pad 311 is fitted on the clamping surface of the clamping plate 31;

[0036] When clamping the mirror tube 6 by the positioning assembly 3, first, hold the pull ring 33 to pull the connecting rod 32 to the side away from the guide tube 2, and rotate the connecting rod 32 so that the latch 321 on the connecting rod 32 is aligned with the clamping guide groove 342 of the clamping guide cylinder 34. Then release the pull ring 33. Under the elastic force of the spring 35, the clamping plate 31 moves toward the side of the mirror tube 6, thereby clamping the mirror tube 6. In addition, the rubber pad 311 is attached to the clamping surface of the clamping plate 31 to increase the friction with the mirror tube 6, making the clamping more stable.

[0037] When releasing the mirror tube 6 from the positioning assembly 3, the pull ring 33 is held to pull the connecting rod 32 to the side away from the guide tube 2, and the connecting rod 32 is rotated so that the pin 321 on the connecting rod 32 is aligned with the slot 341 of the clamping guide cylinder 34. Then the pull ring 33 is released so that the pin 321 on the connecting rod 32 is stuck in the slot 341, so that the clamping plate 31 is released from contact with the mirror tube 6, thereby releasing the clamping of the mirror tube 6.

[0038] The guide tube 1 2 and the guide tube 2 4 are connected, and the central axis of the guide tube 1 2 and the central axis of the guide tube 2 4 are arranged to coincide with each other. The distal end of the guide tube 1 2 is a bell-mouth structure.

[0039] The mirror tube 6 passes from the guide tube 1 2 to the guide tube 2 4 and then extends into the patient's body for examination. The guide tube 1 2 adopts a trumpet structure, which makes it easier for the mirror tube 6 to penetrate into the guide tube 1 2.

[0040] The working principle of the utility model is as follows: when performing bronchoscopic examination on a patient, the lip plate 1 is first placed in contact with the patient's lips, and the guide tube 2 4 is placed in the patient's mouth, and then the mirror tube 6 of the bronchoscope is inserted from one end of the guide tube 1 2, and then enters the patient's mouth through the guide tube 2 4, and then reaches the lesion along the patient's bronchus for examination. When sampling or injection of physiological saline for imaging examination is required, the length of the mirror tube 6 extending into the human body needs to be kept unchanged. The clamping plate 31 of the positioning component 3 can be released to approach the guide tube 1 2, thereby clamping the mirror tube 6, so that the length of the mirror tube 6 in the human body remains unchanged, which is convenient for medical staff to perform examination or sampling.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
