Medical endoscope, inner and outer sheath kits and medical endoscope system

Abstract

The invention provides an endoscope system, as well as an endoscope and inner and outer sheath kits, which can be used for forming the endoscope system, and belongs to the field of medical instruments. The endoscope system comprises the endoscope, a stop catch mechanism and an inner and outer sheath kit set, wherein the inner and outer sheath kit set comprises a plurality of inner and outer sheath kits; each inner and outer sheath kit comprises a clamping unit, an inner sheath and an outer sheath which sleeves the inner sheath and also detachably sleeves a protective casing; a first clamped part is arranged at the part, far away from the inserting end, of the endoscope; a second clamped part is arranged at the part, far away from the inserting end, of each inner sheath; and through clamping match between the clamping units and the first clamped part, as well as between the clamping units and the second clamped parts, the inner sheaths and the endoscope are fixedly connected in a freely mounting and dismounting manner. As for the same endoscope, the inner and outer sheath kits with different sectional sizes can be mounted, the requirements on instrument channels from operations in different fields can be met, accordingly, the endoscope allocation amount can be reduced, the equipment allocation cost and management cost are lowered, the instrument replacement time in an operation can be shortened, and the operation safety is improved.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical endoscope system, and an endoscope and an inner and outer sheath set which can be used to construct the medical endoscope system. Background technique [0002] In recent years, with the development and popularization of minimally invasive surgery, medical endoscope systems have been widely used in orthopedics, spine surgery, gynecology, urology and neurosurgery. The medical endoscope system is usually composed of an endoscope, an inner sheath and an outer sheath fixedly connected with the endoscope. The outer sheath is sleeved outside the endoscope and the inner sheath. There is an imaging optical channel inside. The outer wall of the endoscope, the first channel surrounded by the outer wall of the inner sheath and the inner wall of the outer sheath integrates a water delivery channel, an illumination light channel and a water pumping channel. The illumination light channel usually...

Problems solved by technology

[0003] Although endoscope systems are designed to perform basically the same functions in different fields such as orthopedics, spine surgery, gynecology, urology, and neurosurgery, in order to be able to provide surgeons in different fields with appropriate endoscopic systems , the hospital needs to maintain a large number of different types of endoscope systems, which is not only costly, but also difficult to manage and maintain. In addition, when the same patient needs to perform multiple operations in the same operation, multiple endoscopes need to be prepared during the operation. system, not only increases the cost of the operation, but also makes it difficult for the surgeon to flexibly replace the endoscope system during the operation. At the same time, a large number of disinfection facilities and aseptic facilities are required to match it during the operation, which further increases the operation cost and operation cost. risk
