Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a rigid endoscope with anesthesia and suction functions. Background Technology

[0002] Endotracheal intubation is a medical procedure in which an endotracheal tube is inserted into the trachea through the mouth and glottis. Traditional laryngoscope intubation has drawbacks such as significant invasiveness, numerous side effects, inaccurate intubation, high learning difficulty, and low success rate in patients with difficult airways. Therefore, stylet intubation has become more widely used in clinical practice. Rigid endotracheal intubation, as a stylet intubation technique, is increasingly welcomed by clinicians.

[0003] In clinical practice, many patients have excessive sputum secretion in their respiratory tract due to long-term smoking and inflammatory stimulation. Sputum can easily adhere to the tip of the rigid endoscope, obstructing the operator's field of vision. The presence of sputum seriously affects the operator's judgment of local structures, prolongs the intubation time, and greatly reduces the success rate of rigid endoscope intubation.

[0004] Meanwhile, currently used rigid endotracheal intubation endoscopes do not have the function of airway surface anesthesia. Before performing endotracheal intubation on patients with difficult airways, anesthesiologists often need to use methods such as gargling, cricothyroid membrane puncture, or the application of additional spray devices (such as spray bottles, spray tubes, or inhalers) to apply local anesthetics to the designated site in order to achieve airway surface anesthesia. However, the effectiveness of these methods is often closely related to factors such as the patient's cooperation and the anesthesiologist's skill level, making pre-intubation anesthesia difficult to perform. Utility Model Content

[0005] The main purpose of this application is to provide a rigid endoscope with anesthesia and suction functions, aiming to solve the above-mentioned technical problems.

[0006] The technical solution adopted in this application is as follows:

[0007] A rigid endoscope with anesthesia and suction functions includes a display, a rigid endoscope handle, and a rigid endoscope body. The rigid endoscope body has a built-in camera assembly. An intubation locator is disposed on the side of the rigid endoscope body near the handle. The intubation locator is provided with an oxygen tube connector. A first cavity and a second cavity are provided along the rigid endoscope body. A suction tube is disposed in the first cavity, and an anesthesia tube is disposed in the second cavity. The intubation locator is also provided with a multi-cavity tube connector, which is connected to both the suction tube and the anesthesia tube.

[0008] Optionally, the multi-cavity tube connector has a first core channel and a second core channel independently provided inside. One end of the first core channel is connected to the suction tube, and the other end of the first core channel is provided with a first external interface. One end of the second core channel is connected to the anesthesia tube, and the other end of the second core channel is provided with a second external interface.

[0009] Optionally, the outer wall of the cannula positioner is provided with a T-shaped shaft, and a connecting nut is movably sleeved on the T-shaped shaft.

[0029] See attached document Figure 1 This application provides a rigid endoscope with anesthesia and suction functions, including a display 1, a rigid endoscope handle 2, and a rigid endoscope body 3. The rigid endoscope body 3 has a built-in camera assembly 4. An intubation positioner 7 is provided on the side of the rigid endoscope body 3 near the handle. An oxygen tube connector 10 is laterally connected to the intubation positioner 7. As a conventional structure of a rigid endoscope, this embodiment will not provide a detailed description of the structure of the display 1, the rigid endoscope handle 2, the rigid endoscope body 3, and the intubation positioner 7.

[0030] See Figures 1 to 3 As shown, a first cavity and a second cavity are provided along the rigid endoscope body 3. A suction tube 5 is provided in the first cavity, and an anesthesia tube 6 is provided in the second cavity. Both the suction tube 5 and the anesthesia tube 6 extend out of the rigid endoscope body 3 at the end away from the intubation locator 7. The intubation locator 7 is provided with a first inlet and a second inlet. The suction tube 5 is led out of the rigid endoscope body 3 through the first cavity from the first inlet, and the anesthesia tube 6 is led out of the rigid endoscope body 3 through the second cavity from the second inlet. The intubation locator 7 is provided with a multi-cavity tube connector 8 on the side opposite to the oxygen tube connector 10. Both the suction tube 5 and the anesthesia tube 6 are connected to the multi-cavity tube connector 8.

[0031] It is conceivable that, based on the setup of the suction tube 5 and the anesthesia tube 6, connecting the suction device to the multi-lumen tube connector 8 to form a connection with the suction tube 5 can achieve the suctioning of sputum, avoiding the impact of sputum contact with the camera on the field of vision. At the same time, by connecting the anesthesia syringe to the multi-lumen tube connector 8, the anesthetic solution can be delivered through the anesthesia tube 6 to achieve surface anesthesia of the epiglottis, glottis and subglottis under direct vision. Compared with traditional airway surface anesthesia, the effect is more accurate and the operability is higher.

[0032] In a preferred embodiment, to enable the replacement of the disposable suction catheter 5 and the anesthesia catheter 6, such as... Figure 3As shown, the outer wall of the cannula positioner 7 is integrally formed with a T-shaped shaft, and a connecting nut 12 is movably sleeved on the T-shaped shaft. The outer wall of the multi-cavity tube connector 8 is provided with a threaded connector 807, which is matched and connected with the connecting nut 12, thereby allowing the multi-cavity tube connector 8 to be detachably installed on the cannula positioner 7. Figure 4 As shown, the multi-cavity tube connector 8 has a first core channel 801 and a second core channel 802 independently arranged inside. One end of the first core channel 801 is provided with a first tube connector 805, and the suction tube 5 is interference-fitted onto the first tube connector 805. The other end of the first core channel 801 is provided with a first external interface 803, which is used to connect with the suction device. One end of the second core channel 802 is provided with a second tube connector 806, and the anesthesia tube 6 is interference-fitted onto the second tube connector 806. The other end of the second core channel 802 is provided with a second external interface 804, which is used to connect with the anesthesia injector.

[0033] As can be imagined, when it is necessary to replace the used disposable suction catheter 5 and anesthesia tube 6, the connecting nut 12 is screwed toward the intubation positioner 7, separating the connecting nut 12 from the threaded connector 807. Since both the suction catheter 5 and the anesthesia tube 6 have a section protruding from the rigid endoscope body 3, after the connecting nut 12 is separated from the threaded connector 807, the multi-lumen connector 8 can be pulled out a distance. At this time, the suction catheter 5 can be removed from the first connector 805, and the anesthesia tube 6 can be removed from the second connector 806. After removal, the suction catheter 5 and the anesthesia tube 6 are pulled out of the first and second lumens from the end away from the intubation positioner 7. Then, the new suction catheter 5 and the anesthesia tube 6 are inserted into the first and second lumens from the end away from the intubation positioner 7 and connected to the multi-lumen connector 8. The connecting nut 12 is then screwed toward the multi-lumen connector 8, so that the connecting nut 12 is threadedly connected to the threaded connector 807.

[0034] In addition, such as Figure 2 and Figure 4 As shown, the end of the anesthesia tube 6 furthest from the intubation positioner 7 is equipped with a nebulizing nozzle 9. The nebulizing nozzle 9 delivers anesthetic solution as a water mist to the affected area for anesthesia. Specifically, the nebulizing nozzle 9 has an axially direct main channel 901, which is X-shaped, allowing the anesthetic solution to be sprayed out at a high velocity. Simultaneously, branch channels 902 are arranged circumferentially around the main channel 901. It should be noted that the sum of the flow rates at the smallest inner diameter of the branch channels 902 and the main channel 901 is less than the flow rate at the inlet of the nebulizing nozzle 9, thus creating a turbulent flow on the outlet side. Furthermore, the outflow direction of the main channel 901 is perpendicular to the outflow direction of the branch channels 902, creating convection and breaking the solution into smaller droplets. The nebulizing nozzle 9 is equipped with an outlet 903, which has several micropores evenly distributed throughout, ultimately resulting in nebulized drug delivery.

[0035] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
