Description
Technical field
This utility model relates to the additional device of ureteroscope, particularly about the improved handle hole water shutoff of a kind of ureteroscope cap.
Background technology
The operating side of the existing ureteroscope for urology procedure is respectively equipped with inlet opening, apopore and handle hole, and handle hole can penetrate respectively according to requirements of operation the operation devices such as rubble bar, lithotomy forceps, laser fiber.For preventing being flowed out from handle hole by the water of inlet opening input pipe mirror in operation, at operation nose end button, be furnished with capping, the center of capping capping is porose, so that penetrate the operation devices such as rubble bar, lithotomy forceps, laser fiber, implements operation.But, owing to not being provided with hermetically-sealed construction between the operation devices such as existing capping centre bore and rubble bar, lithotomy forceps, laser fiber.Therefore the water that enters ureteroscope by inlet opening in operation can flow out through capping, the water of seepage not only affects doctor's operation technique, and can give operation technique environment and bring unnecessary trouble.
Utility model content
The purpose of this utility model is for preventing or stopping ureteroscope fault of construction from handle hole capping percolating water in operation process, and proposes a kind of water shutoff cap with favorable sealing property.For realizing this object, the technical scheme adopting is: the improved handle hole water shutoff of a kind of ureteroscope cap, comprise capping, it is characterized in that capping is provided with connected trocar sheath, between capping and trocar sheath abutting end, be provided with seal closure, in trocar sheath, be provided with inner catheter, capping and trocar sheath are connected for withholding; The nose end that trocar sheath and capping fasten is provided with recessed conical ring in pipe, and capping is provided with the taper capping of indent, and the tapering of trocar sheath conical ring equates with the tapering of capping taper capping, and the cone tip of capping taper capping is provided with hole; Inner catheter is located at trocar sheath Nei center, and inner catheter is placed in that nose end in trocar sheath is provided with flange and outer sleeve inner wall is affixed; Seal closure is arranged to taper, and the tapering of cone-shaped hood is less than the tapering of capping taper capping, and the cone tip of cone-shaped hood is provided with aperture; The pipe outer wall that trocar sheath and capping button are joined joint is provided with a circle fin, and the lid mouth of capping is provided with the edge prolonging in a circle; The fin that prolongs edge and trocar sheath outer wall in capping lid mouth is respectively equipped with the gap that interval disconnects; Cone-shaped hood is made by silica gel material; Capping and trocar sheath are made by plastic material.
Press the water shutoff cap that such scheme is implemented, owing to being provided with the cone seal cover of being made by silica gel between capping and overcoat, cone seal cover not only has good reverse hydraulic pressure resistance performance, and has equally good conical ring sealing effectiveness at the abutting end of capping and trocar sheath.This utility model has stopped from configuration aspects the defect that handle hole capping is leaked, and it is rational in infrastructure simple and direct, for patient implements Ureteroscopy, provides safe and reliable apparatus and good operating environment.
Accompanying drawing explanation
Fig. 1 is longitudinal section structural representation of a kind of embodiment of this utility model.
The specific embodiment
With regard to this embodiment, be described in further detail by reference to the accompanying drawings.Capping 2 by transparent molding material system is provided with connected trocar sheath 1, for penetrating the operation devices such as rubble bar, lithotomy forceps, laser fiber, trocar sheath 1 Guan Nei center is provided with inner catheter 10, and it is affixed with outer sleeve inner wall that the nose end of inner catheter 10 in being placed in trocar sheath 1 is provided with flange 110.For realizing, stop leaking of capping, between capping 2 and trocar sheath 1 abutting end, be provided with the cone seal cover 3 of being made by silica gel material, because capping 2 and trocar sheath 1 are connected for withholding, for creating similar sealing gasket effect, at trocar sheath 1 and the nose end that capping 2 fastens, be provided with recessed conical ring 12 in pipe, capping 2 is provided with the taper capping 21 of indent, and for compressing cone seal cover 3, the tapering of trocar sheath conical ring 12 is made identical tapering with the tapering of capping taper capping 21.For penetrating operation device, at the cone tip of capping taper capping 21, be provided with hole 20, in like manner, the cone tip of cone seal cover 3 is equipped with aperture 30.Because this seal closure is to make by having certain elastic silica gel material, when the operation devices such as rubble bar, lithotomy forceps, laser fiber are when through this aperture, can the device penetrating be wrapped in closely wherein and can not produce drainage because of its good elasticity.Moreover the tapering being equal to due to capping taper capping and trocar sheath nose end conical ring, closely detains timing when capping and trocar sheath, causes cone seal cover closely to be pushed down, so played the effect of similar sealing gasket.For effectively realizing this design, the tapering of cone seal cover should be less than the tapering of capping taper capping, this structure makes cone seal cover and flowing water form the effect with reverse opposing hydraulic pressure, and above-mentioned two places are for preventing and stop the vital structure of capping percolating water defect place.For making capping and trocar sheath detain closely to connect, close, the pipe outer wall of joining joint at trocar sheath 1 and capping 2 buttons is provided with a circle fin 13, the lid mouth of capping 2 is provided with the edge 22 prolonging in a circle, because capping is to be made by plastic material, when capping button is assigned in to trocar sheath, the elasticity at capping Gai Kou edge 22 can be crossed the fin 13 of sleeve pipe peripheral hardware and the two is closely fastened.Also can adopt the button of interlaced rotation pressing to join formula structure herein, the fin that prolongs edge and trocar sheath outer wall in soon capping lid mouth is respectively arranged with the separated gap of phase of equalization, namely common capping Gai Kou edge and trocar sheath fin are respectively equipped with the gap at interval, when the two button timing, the gap that the chimb at the interval of capping is aimed at trocar sheath interval rotatably compresses again.So, capping 2 with tight connection of cone seal cover 3 and trocar sheath 1 form the said water shutoff cap of this utility model.Water shutoff cap for ease of with being connected of ureteroscope operation nose end, in the trocar sheath other end mouth of pipe, be shaped with and the screw thread 11 that operates nose end and spin.
