Description

Technical Field

[0001] This utility model relates to a detachable endoscope sheath, belonging to the field of medical devices. Background Technology

[0002] An endoscope is a device equipped with an imaging endpiece that enters the body through natural openings or small surgical incisions. When used, the endoscope is guided into the organ to be examined, allowing direct visualization of the affected area. This helps doctors conduct a more comprehensive examination of the cavity and perform surgery under direct visualization, significantly improving surgical safety.

[0003] As a common accessory for endoscopes, the endoscope sheath is generally used to create a channel in the human body with the puncture needle. A water valve is integrated into the sheath for flushing during surgery. Currently, the sheath used to create this channel is first fitted onto the puncture needle before being inserted into the body, and then the puncture needle is removed before the endoscope is inserted through the sheath. Currently, most sheath assembly 1 and water valve assembly 2 are integrated, meaning they are fixed together. Replacing sheath assembly 1 requires simultaneous replacement of water valve assembly 2, increasing surgical costs. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings in the existing technology and to provide a detachable mirror sheath with a reasonable structural design.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: The detachable mirror sheath includes a sheath tube assembly and a water valve assembly. The sheath tube assembly is connected to the water valve assembly. Its structural feature is that the sheath tube assembly and the water valve assembly are set as separate structures. The sheath tube assembly includes a sheath tube body and a sheath tube connector. The sheath tube body and the sheath tube connector are fixed. The water valve assembly includes a water valve connector seat, a water valve connector bridge, a water valve seat, a water valve body, and an interface. The water valve seat is set on the water valve connector seat. The water valve connector bridge is set inside the water valve connector seat and passes through the water valve seat. The water valve body is set on the water valve seat. The interface is set on the water valve connector bridge. The sheath tube connector is snapped into the water valve connector seat and connected to the water valve connector bridge.

[0006] Furthermore, a sheath tube lever is provided on the sheath tube connector, and a water valve lever is provided on the water valve connector.

[0007] Furthermore, the sheath connector is provided with a locking groove, the end of the locking groove is provided with a retaining groove, and the water valve connector is provided with a locking rod, which cooperates with the locking groove.

[0008] Furthermore, a sealing cap is provided on the interface.

[0009] Furthermore, a first sealing ring is provided between the sheath connector and the water valve connecting bridge, and a second sealing ring and a third sealing ring are provided between the first sealing ring and the water valve seat.

[0010] Furthermore, the detachable mirror sheath is used in conjunction with a closed aperture device, which includes a closed aperture device body and a closed aperture device handle, with the closed aperture device body mounted on the closed aperture device handle.

[0011] Furthermore, the locking groove is configured in an L-shape.

[0012] Compared with the prior art, this utility model has the following advantages: the sheath tube assembly and the water valve assembly in the detachable sheath are set as separate structures. In use, the sheath tube assembly is first used in conjunction with the obturator to puncture the human body. After puncture, the obturator can be removed, and then the water valve assembly and the sheath tube assembly can be assembled. That is to say, the same water valve assembly in the detachable sheath can be used with multiple models of sheath tube assemblies. At the same time, the same obturator handle can also be used with multiple models of obturator bodies. The model of the obturator body matches the model of the sheath tube assembly.
