Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laparoscope lens protection, in particular to a track-type protective sleeve film for preventing laparoscope lens from being contaminated. Background Art
[0002] When examining the patient's abdominal cavity, a laparoscope is used. Similar to an electronic gastroscope, a laparoscope is a medical device with a miniature camera. Laparoscopic surgery is performed using a laparoscope and its related instruments. Currently, when examining with a laparoscope, the lens is in direct contact with the surgical field and cannot be kept clean. A contaminated or fogged lens cannot guarantee a clear surgical field of view, and the lens needs to be frequently wiped externally, resulting in a waste of time and a poor surgeon experience, which in turn results in low surgical continuity and efficiency and a long operation time. Therefore, there is an urgent need for a track-type protective sleeve that can prevent contamination of the laparoscope lens to solve the above technical problems. Utility Model Content
[0003] The utility model aims to provide a track-type protective sleeve film for preventing contamination of a laparoscope lens, so as to solve the problems raised in the above-mentioned background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A track-type protective sleeve film for preventing contamination of a laparoscope lens comprises a hard sealing shell, a protective film track is arranged inside the hard sealing shell, a protective film is arranged inside the protective film track, a laparoscope lens protection area is arranged at the bottom of the hard sealing shell, a sleeve inlet is arranged at the top of the hard sealing shell, a film-releasing pulley is arranged on the inner side wall of the hard sealing shell, a film-collecting pulley is arranged on the inner side wall of the hard sealing shell and located on the right side of the film-releasing pulley, two ends of the protective film are respectively entangled on the film-releasing pulley and the film-collecting pulley along the protective film track, and an arc opening is opened on the hard sealing shell and located on one side of the film-releasing pulley and the film-collecting pulley.
[0006] As a preferred technical solution of the utility model, the top end of the protective film passes through the laparoscope lens protection area.
[0007] As a preferred technical solution of the utility model, the film collecting pulley and the film unwinding pulley have the same size and are at the same horizontal height.
[0008] As a preferred technical solution of the utility model, there is a distance between the film collecting pulley and the film unwinding pulley.
[0009] As a preferred technical solution of the utility model, the protective film is moved in a belt-like rolling manner using an external pulley.
[0010] As a preferred technical solution of the utility model, the arc-shaped opening faces the protective film, and the width of the protective film is the same as the width of the arc-shaped opening.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model sleeves a hard sealing sleeve shell equipped with a protective film track on the lens body of the laparoscope, thereby avoiding direct contact between the lens and the surgical field and keeping the lens clean.
[0013] When the top of the protective film is contaminated, the utility model uses an extracorporeal pulley belt rolling method to move the clean protective film belt area in front of the lens, and the contaminated or fogged protective film area is removed from the field of view, ensuring the clarity of the surgical field of view, avoiding the time waste caused by frequent extracorporeal wiping of the lens, improving the surgeon's experience, improving the continuity and efficiency of the operation, and shortening the operation time.
