Description

Technical Field

[0001] The utility model relates to the technical field of otolaryngology equipment, in particular to an automatic nasal endoscope flushing device. Background Art

[0002] Nasal endoscope is an ENT device, an optical device that can perform detailed examination of the nasal cavity. It generally refers to a hard tube endoscope with angles ranging from 0 to 90 degrees. Due to good lighting and its thinness, the diameter is only 2.7-4.0mm, but nasal endoscope is sometimes also referred to as a soft tube endoscope. Nasal endoscope can easily pass through the narrow nasal cavity and nasal passages to examine the internal structure of the nasal cavity, nasopharynx and even sinuses. It is an important means of diagnosing sinusitis and nasal polyps. With the matching surgical instruments, it can also perform fine treatment of sinusitis and nasal polyps, allowing surgery to reach areas that traditional surgery cannot reach.

[0003] However, when it is used in surgery, there will be a more difficult problem. The patient's nose often bleeds, making the lens blurry. Therefore, the doctor needs two people to cooperate, one to check and the other to drip water down the metal tube with a syringe, which is very troublesome. In addition, the blood will also cause severe discomfort and discomfort to the patient, causing the patient to move unconsciously. The patient's unconscious movement often seriously interferes with the treatment work of medical workers, and in severe cases, it will lead to poor medical results or even medical accidents. Utility Model Content

[0004] The utility model aims to provide an automatic nasal endoscope flushing device, which can solve the problem that the lens of the nasal endoscope is blurred and difficult to clean during the operation.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] An automatic nasal endoscope flushing device comprises a gripping portion and an insertion tube mounted at the lower end of the gripping portion, wherein a data line and a camera connected to the data line are mounted inside the insertion tube. A flushing assembly is arranged outside the insertion tube. The flushing assembly comprises a shell, a drainage tube and a rubber ball. The shell is arranged outside the end of the insertion tube, and the opening of the shell is in a constricted shape; the drainage tube is attached to the outer wall of the insertion tube; a cavity is arranged inside the rubber ball, and the two ends of the drainage tube are respectively connected to the inside of the shell and the cavity inside the rubber ball. The rubber ball is connected to an external infusion bottle through an external infusion tube.

[0007] Preferably, the two ends of the rubber ball are respectively provided with a liquid outlet and a liquid inlet connected to the cavity. The liquid outlet and the liquid inlet are both provided with anti-reflux valves to prevent the liquid inside the rubber ball from flowing back to the external infusion bottle.

[0008] Preferably, the liquid outlet interface is connected to a drainage tube, and the liquid inlet interface is connected to an external infusion tube.

[0009] The utility model uses a rubber ball to squeeze the liquid in the external infusion bottle into the drainage tube, and guides the liquid to the end of the insertion tube, so as to clean the camera. The problem that the lens of the nasal endoscope is blurred and difficult to clean during surgery is solved. The rubber ball can automatically store water; and the shell with a constricted mouth can make the water flow form a vortex, so as to clean the camera more effectively.

[0019] Embodiment 1

[0020] The utility model provides a rubber ball to squeeze the liquid in the external infusion bottle into the drainage tube, and guides the liquid to the end of the insertion tube, so as to clean the camera, thereby solving the problem that the lens of the nasal endoscope is blurred and difficult to clean during the operation.

[0021] like Figure 1-3 As shown, an automatic nasal endoscope flushing device includes a gripping portion 1 and an insertion tube 2 installed at the lower end of the gripping portion 1, wherein a data line 21 and a camera 22 connected to the data line are installed inside the insertion tube 2. A flushing assembly 3 is arranged on the outside of the insertion tube 2. The flushing assembly 3 includes a shell 31, a drainage tube 32 and a rubber ball 33. The shell 31 is sleeved on the outside of the end of the insertion tube 2, and the opening of the shell 31 is in a constricted shape. The constricted structure design is conducive to the water flow converging in the shell 31 to form a water flow vortex, thereby more effectively cleaning the camera 22.

[0022] The drainage tube 32 is attached to the outer wall of the insertion tube 2; a cavity 334 is provided inside the rubber ball 33, and the two ends of the drainage tube 32 are respectively connected to the inside of the shell 31 and the cavity 334 in the rubber ball 33. The rubber ball 33 is connected to an external infusion bottle through an external infusion tube.

[0023] The cavity 334 is used to contain liquid, and when the cavity is squeezed, the liquid is discharged from the rubber ball 33 to form a low pressure. When the rubber ball 33 returns to its original spherical shape due to its elasticity, it can absorb the liquid in the external infusion tube and store it in the cavity.

[0024] Furthermore, the two ends of the rubber ball 33 are respectively provided with a liquid outlet interface 331 and a liquid inlet interface 332 connected to the cavity 334. The liquid outlet interface 331 and the liquid inlet interface 332 are both provided with an anti-reflux valve 333 to prevent the liquid inside the rubber ball 33 from flowing back to the external infusion bottle. The function of the anti-reflux valve 333 is to prevent the liquid in the drainage tube 32 from flowing back into the cavity 334, and also to prevent the liquid in the cavity 334 from flowing back into the external infusion tube, so as to ensure that the liquid can be supplied to the drainage tube 32.

[0025] Furthermore, the liquid outlet interface 331 is connected to the drainage tube 32. The liquid inlet interface 332 is connected to an external infusion tube.

[0026] Working principle:

[0027] When the camera 22 needs to be cleaned, the rubber ball 33 is squeezed. At this time, the space in the cavity 334 is reduced, the pressure is increased, the liquid outlet interface 331 is in an open state, and the liquid inlet interface 332 is in a closed state. The liquid in the cavity 334 will flow into the shell 31 along the drainage tube 32, and form a vortex in the shell 31 to flush the camera 22. After the rubber ball 33 is squeezed and deformed, it will automatically return to its original shape due to elasticity. At this time, the space in the cavity 334 becomes larger, the pressure is reduced, the liquid outlet interface 331 is in a closed state, and the liquid inlet interface 332 is in an open state. The cavity 334 is negatively pressurized, which attracts the liquid in the external infusion tube to flow into the cavity 334, and the cavity 334 is refilled with water for the next use.

[0028] In the description of the present invention, it should be understood that the terms "middle", "length", "up", "down", "front", "back", "vertical", "horizontal", "inside", "outside", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In the present invention, unless otherwise clearly specified and limited, the first feature "on" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. "Multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
