Description

Improved structure of laparoscope

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an improved structure of a laparoscope.

Background

The laparoscope is similar to an electronic gastroscope and is an instrument with a miniature camera, the laparoscopic surgery is a surgery carried out by utilizing the laparoscope and related instruments thereof, the laparoscopic surgery is widely carried out in the field of surgery, and is popular with patients due to the advantages of small wound, quick recovery and the like, the laparoscope in the prior art has the structure that the head of a tubular puncture sheath is an oblique angle of 45 degrees, the inner surface is smooth, the inner diameter is 12mm, the rear part of the puncture sheath is a conversion part with the enlarged diameter, an air inlet pipe and an air inlet valve for introducing carbon dioxide gas into the circular pipe are arranged on the conversion part, a valve handle for opening and closing the circular pipe passage is further arranged in the axial direction of the conversion part, when the handle is pressed, the circular pipe passage is opened, an observation mirror can extend into the circular pipe from the tail part above. The observation mirror is a metal round bar with the outer diameter of 10mm, the end part of the observation mirror is a camera mirror with a 12-degree inclined plane, a video wire is led out outwards to be connected with a computer, and the total length of the metal round bar of the observation mirror is about 350 mm.

In laparoscopic surgery, a 12-degree standard observation mirror with the outer diameter of 10mm is required to be arranged in a puncture sheath, and a camera monitoring system is connected for displaying the operation visual field in the operation. The traditional puncture sheath used for placing the observation mirror is a metal or plastic sleeve with the inner diameter of 12mm, the inner surface is smooth, and a gap between the observation mirror and the puncture sheath can be used for carbon dioxide gas to enter and exit. However, in practical application, it is found that when the observation lens is polluted by tissue fluid such as blood, and when the observation lens is removed from the puncture sheath, and the cleaning process is performed, a part of blood adheres to the inner surface of the puncture sheath, because the sight line direction of the observation lens forms an angle of 12 degrees with the long axis of the endoscope body, the direction of the observation lens is not easy to be grasped by a beginner, when the observation lens is placed into the observation lens again, the observation lens is easy to be polluted again, so that repeated cleaning of the observation lens increases meaningless operation time and increases potential operation risks, at present, if the blood in the endoscope sheath repeatedly pollutes the lens, a forceps holder 1/4 is generally adopted to clean the inner surface of the puncture sheath with a small gauze, the small gauze is required to be completely passed through the puncture sheath and then pulled out, otherwise, the endoscope is easy to be blocked in the puncture sheath, but the operation under blind vision has the risk of damaging the blood vessels, the operation time is prolonged, so that a puncture sheath structure which has a simple structure and is convenient to use and can prevent and reduce the tissue fluid such as blood from polluting the lens of the observation mirror is provided.
