| description | Disclosed are a sheath cap and an endoscope introducer sheath with the sheath cap. The sheath cap comprises a housing collar (1) and a cylinder (2) which is coaxially fixed on an inner surface of one end of the housing collar (1), wherein the cylinder (2) is internally provided with instrument channel straight holes (15, 16) and a water spray channel straight hole (3) which are parallel to an axial direction of the cylinder, and the sheath cap is provided with a water spray channel oblique hole (4), which is in communication with the water spray channel straight hole (3) and can spray water to the lateral front side of the sheath cap. By designing the form of a combined hole structure combining the water spray channel straight hole (3) and the water spray channel oblique hole (4) in the sheath cap, a water flow entering from the endoscope introducer sheath can be simultaneously sprayed to the front and the side of a calculus point in front of the sheath cap, such that broken calculi at the calculus point are subjected to multi-angle washing, thereby increasing the probability of separation between the broken calculi and the calculus point, and ensuring the washing effect of the water flow on the broken calculi. |
