Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a nasal endoscope with a lens cleaning device. Background Art

[0002] The statements in this section merely provide background information related to the present application and may or may not constitute prior art.

[0003] Endoscopic nasal surgery refers to the technique of using a nasal endoscope and special surgical instruments to perform surgery on the nasal cavity, paranasal sinuses, nasal orbits, and skull base through the nasal cavity with the support of an optical system and a monitoring system. Since the nasal cavity is a narrow, long, and deep space with dense nerves and blood vessels, endoscopic nasal surgery is more conducive to the refined operation of nasal surgery.

[0004] When performing surgery in the narrow space of the nasal cavity, the surgeon often faces the problem that the blood or residual tissue debris in the surgical cavity often contaminates the endoscope lens. The current common practice is to require another assistant to use saline to flush the nasal cavity with a syringe outside the nasal cavity. Although this method is widely used, it is inefficient and often fails to effectively clean the lens. Endoscopic nasal surgery requires the cooperation of two doctors and also occupies a large amount of medical resources.

[0005] Therefore, developing and designing a new type of nasal endoscope that can be used to clean the lens with one hand during surgery is a very urgent need in the clinical practice of otolaryngology and head and neck surgery. Utility Model Content

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Example 1

[0029] See also Figure 1 to Figure 6 As shown, the utility model provides a nasal endoscope with a lens cleaning device, comprising a gripping section 1, a control section 2 and an insertion section 3, the insertion section 3 comprising an outer pipe 301 and an inner pipe 302 which are nested and spaced apart, a lens 4 of the nasal endoscope is mounted at the front end of the inner pipe 302, a boss 303 is provided on the outer wall of the inner pipe 302 at one end close to the lens 4, a wiping member 5 is mounted on the boss 303, an operating handle 6 is provided on the outer side of the end of the outer pipe 301 close to the control section 2; the operating handle 6 is connected to the wiping member 5 through a guide wire 7, and is used for manually controlling the wiping member 5 to periodically reciprocate and wipe the mirror surface of the lens 4, an elastic reset member is provided on the wiping member 5 and is connected to the inner pipe 302, and is used for driving the wiping member 5 to reset when the operating handle 6 is manually released.

[0030] A manual cleaning structure involved in this embodiment is achieved by improving the structure of the nasal endoscope. A lens cleaning structure is provided at the front end of the insertion section 3 of the nasal endoscope. The wiper 5 is driven to move by pulling the operating handle 6 via the guide wire 7 to wipe off dirt on the lens surface 4. When the operating handle 6 is released, the wiper 5 elastically returns to its original position to wipe back, and the lens cleaning can be completed with one hand.

[0031] In this embodiment, when the wiping member 5 is connected to the operating handle 6 through the guide wire 7, a groove 304 is provided on the boss 303, and the wiping member 5 is an elastic silicone structure 8 that is normally contracted in the groove 304; the elastic silicone structure 8 includes an arc-shaped upper side strip 801, an arc-shaped lower side strip 802, and an elastically shrinkable silicone sheet 803 under normal conditions, the arc-shaped upper side strip 801 is fixed to the bottom of the groove 304, and the arc-shaped upper side strip 801 is connected to the arc-shaped lower side strip 802 through the silicone sheet 803; the front end of the guide wire 7 is divided into two branches that are respectively connected to the two ends of the arc-shaped lower side strip 802. Under normal conditions, the silicone sheet 803 shrinks, so that the entire elastic silicone structure 8 shrinks in the groove 304. As the guide wire 7 pulls the arc-shaped lower side strip 802 downward, the silicone sheet 803 will be thinned and the elastic deformation will gradually extend, and the arc-shaped lower side strip 802 will gradually scrape off the dirt on the mirror surface. After letting go, the silicone sheet 803 will shrink upwards under the action of the elastic restoring force, driving the arc-shaped lower edge strip 802 to shrink back into the groove.

[0032] In this embodiment, two guide hooks 9 are arranged on the inner wall of the front end of the outer pipe 301, and the two branches from the front end of the guide wire are respectively passed around the corresponding guide hooks 9. The guide hook 9 is designed to change the pulling direction of the guide wire. It can be seen from the attached figure that the guide wire needs to be guided to pull the arc-shaped lower edge strip 802 downward so that the arc-shaped lower edge strip 802 can sweep a larger lens surface as much as possible.

[0033] In this embodiment, the end of the boss 303 close to the lens protrudes from the end face of the inner pipe, the notch of the groove 304 of the boss 303 is flush with the end face of the inner pipe 302 and the mirror surface of the lens 4, and the end face of the boss 303 protruding from the inner pipe 302 is flush with the outer end face of the outer pipe 301.

[0034] In this embodiment, a fixing plate 305 is provided on the inner wall of the outer pipe 301, one end of the operating handle 6 is connected to the guide wire 7 and the other end is connected to the fixing plate 305 through a reset spring 306, so that the operating handle 6 can be quickly reset along with the reset spring 306 after the hand is released. A sliding groove is provided through the outer pipe 301, and the operating handle 6 can slide back and forth in a straight line in the sliding groove.

[0035] In this embodiment, the nasal endoscope also includes a plurality of flushing tubes fixed between the outer pipe 301 and the inner pipe 302. The water inlet end of the flushing tube passes through the outer pipe and is connected to a water storage bag through a micro water pump. The water outlet end of the flushing tube points to the mirror surface of the lens. A flushing button for starting and stopping the micro water pump is also provided on the outer pipe 301.

[0036] Example 2

[0037] like Figures 7-9As shown, the main structure of the nasal endoscope in this embodiment is the same as that of the previous embodiment, except that the cleaning device is designed as an electric cleaning structure, and the operating handle 6 is connected to the wiping member 5 through a wire and a micro motor 10. The operating handle 6 can be a button design, which is used to start and stop the micro motor 10 to electrically control the wiping member 5 to periodically reciprocate and wipe the mirror surface of the lens 4. The micro motor 10 at the front end is started and stopped by the operating handle 6, and the motor controls the wiping member to reciprocate and wipe on the mirror surface of the lens to remove dirt according to a preset program.

[0038] In this embodiment, the wiping member 5 is a brush rod 11 arranged close to the mirror surface, the surface of the brush rod 11 is provided with bristles, a rotating rod 12 is passed through the boss 303, the micro motor 10 is installed on the inner side of the boss 303 and the output shaft of the micro motor 10 is transmission connected to the rotating rod 12, and the end of the rotating rod 12 away from the micro motor is vertically connected to the brush rod.

[0039] In this embodiment, a boss 303 is respectively provided on the top and bottom sides of the inner pipe 302, and two groups of micro motors 10, brush rods 11, and rotating rods 12 are adapted. In this design, the brush rod can be designed to be shorter. When cleaning, the upper and lower brush rods sweep the lens surface at the same time, with high cleaning efficiency and less chance of cleaning dead corners.
