Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an endoscope lens foreign body removal device. Background Technology

[0002] With the rapid development of medical technology, minimally invasive surgery has been widely used in various fields such as digestive tract (e.g., gastrointestinal) surgery and biliary tract surgery due to its advantages of less trauma and faster recovery. As a core piece of equipment in minimally invasive surgery, the clarity of the endoscope lens directly affects the accuracy and safety of the procedure. However, in actual surgical procedures, the endoscope lens is often obstructed by various foreign objects (such as undigested food residue, feces, bleeding, fat, etc.), resulting in blurred vision and seriously affecting the surgical operation.

[0003] To address this issue, several endoscope lens cleaning devices have been proposed in the prior art. For example, patent number CN216364085U discloses an endoscope camera cleaning device that uses a push-pull movable steel wire to rotate the brush handle, thereby cleaning the lens. However, this device has significant drawbacks: the brush bristles are prone to detachment, potentially leaving foreign objects that irritate the digestive tract; simultaneously, the hard material of the brush may damage the hydrophobic coating of the lens, affecting its performance; furthermore, its transmission structure is complex and its size is large, making it unsuitable for use with endoscopes with small-diameter instrument channels, thus limiting its application range.

[0004] Another patent, CN118902366A, provides an endoscope lens cleaning device that uses a transmission belt to actuate a cleaning block to wipe the lens. However, this device needs to be pre-assembled and inserted into the body, increasing the overall outer diameter of the instrument and causing inconvenience during surgery; at the same time, it cannot be used with endoscopes other than 0° endoscopes, limiting its versatility. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an endoscope lens foreign body removal device. This device removes foreign bodies using two methods: first, by flushing with appropriately pressurized saline solution to remove non-stubborn foreign bodies from the lens; second, by using a cleaning head with silicone bumps that bends and extends from the catheter to scrape off stubborn foreign bodies attached to the lens. This design not only improves cleaning efficiency and reduces surgical time but also alleviates patient discomfort. Simultaneously, the soft material of the silicone brush head prevents damage to the lens and hydrophobic coating, protecting the endoscope's performance.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An endoscope lens foreign body removal device includes a handle, an inner tube assembly, and an outer tube assembly. The handle is connected to the inner tube assembly, and the outer tube assembly is sleeved outside the inner tube assembly.

[0008] Furthermore, the handle includes a fixed ring, a drive ring, a fixed cap, a protective sleeve, and a positioning clip. The drive ring is mounted on the fixed ring via the positioning clip, and the positioning clip is mounted on the fixed ring and engaged with the drive ring. The end of the fixed ring is connected to the protective sleeve via the fixed cap.

[0009] Furthermore, the fixing ring is an integrated ring-cylinder structure, with a guide groove on the fixing ring for sliding with the positioning clamp, and a cylinder on the fixing ring for sliding with the drive ring.

[0010] Furthermore, the drive ring is provided with guide rings symmetrically on both sides, and a sleeve for connecting the guide rings is provided in the middle, and the sleeve is provided with a groove for engaging the positioning clamp.

[0011] Furthermore, the inner tube assembly includes an inner spring tube, a water injection tube, and a silicone brush head. The water injection tube is obliquely disposed at the front end of the inner spring tube. The cavity of the water injection tube is connected to the inner spring tube. The water injection tube is located in the tube section between the drive ring and the fixing cap. The inner spring tube is snapped and fixed with the positioning clamp. The silicone brush head is embedded in the end of the inner spring tube.

[0012] Furthermore, both the fixing cap and the protective sleeve are provided with through holes for the inner spring tube to pass through.

[0013] Furthermore, the silicone brush head includes silicone bumps and a water outlet. The silicone bumps are multiple cylindrical protrusions, evenly distributed on the side wall of the top of the silicone brush head, and connected to the inner spring tube.

[0014] Furthermore, the outer tube assembly includes an outer spring tube and an outer protective sleeve, with the outer protective sleeve fitted onto the outer spring tube; the outer spring tube is fitted onto the inner spring tube, and the two slide relative to each other.

[0015] Furthermore, the front end of the inner spring tube is closed and has a cylindrical protruding structure.

[0016] Furthermore, the section of the inner spring tube inlaid with the silicone brush head is made of nickel-titanium shape memory alloy.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) This invention combines rinsing and scraping to efficiently remove foreign objects from the endoscope lens. For non-stubborn foreign objects, they can be quickly removed by rinsing with saline solution under appropriate pressure; for stubborn foreign objects, they can be scraped off using a cleaning head with silicone bumps. The two methods can be flexibly switched, greatly improving cleaning efficiency and ensuring the clarity of the surgical field.

[0019] (2) During endoscopic surgery, when the endoscope lens is obstructed by foreign objects, the traditional method requires the endoscope to be removed from the digestive or bile duct for cleaning. This not only prolongs the operation time but also increases the patient's pain. However, this invention can clean the endoscope lens directly within the endoscopic instrument channel when it is contaminated, without removing the endoscope, thus significantly reducing the patient's pain.

[0020] (3) The silicone brush head structure used in this invention has soft silicone bumps that will not damage the lens and hydrophobic coating. Compared with the hard brushes or scraping tools used in the prior art, this invention can better protect the endoscope lens and its surface hydrophobic coating, and extend the service life of the endoscope.

[0021] In summary, the endoscopic lens foreign body removal device of this utility model has significant advantages and improvements in cleaning efficiency, patient pain reduction, and lens and hydrophobic coating protection. It not only improves the safety and accuracy of endoscopic surgery, but also enhances the patient's medical experience. Attached Figure Description
