Abstract
The invention relates to a screw dilator capable of feeding lubricating agent. The screw dilator comprises a dilating catheter, wherein a connector is formed at the tail end of the dilating catheter; a guide orifice communicated with the connector is arranged in the dilating catheter; a guide thread groove for flow guidance is formed in the outer wall of the front end of the dilating catheter; a plurality of guide holes communicated with the guide orifice are formed in the thread groove. The screw dilator has a simple structure, is convenient to manufacture and use, can ensure that the lubricating agent completely lubricates the guide orifice according to thread lines formed by the thread groove through the thread groove, has a good lubricating effect, can conveniently inject the lubricating agent through combination design of the tail end connector of the dilating catheter, the internal guide orifice and the guide holes in the thread groove, realizes continuous feeding of the lubricating agent in the condition that the surgical operation is not affected, and realizes continuous lubricating because the lubricating agent flows out through the guide hole.
Description
Technical field
The invention belongs to technical field of medical instrument, be specifically related to a kind of screw thread dilator supplying lubricant.
Background technology
Be applied to the dilator used in urethra or stricture of ureter dilatation and fascia expansion at present in use, there is the rear incarceration of expansion dangerous and the problem be not drawn out easily, and traditional divulsor in use, lubricant by during urethra particularly narrow section time can be adhered to or be wiped off, dilator enter more front end time can not be lubricated, more obvious when complex urethral stricture is expanded especially.The divulsor of current use mostly is cylindrical, easily forms urethra or dilator " locking " is formed incarceration by ureter, after forming " locking " phenomenon, then moves dilator and easily causes urethra or injury of ureter.
Summary of the invention
The object of the invention is to the problem overcoming prior art, a kind of screw thread dilator supplying lubricant is provided.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of screw thread dilator supplying lubricant, its special character is: the described screw thread dilator supplying lubricant comprises a dilating catheter, the end of described dilating catheter have interface and in establish the water conservancy diversion tract that communicates of interface therewith, the front end outer wall of described dilating catheter is arranged the thread groove of water conservancy diversion, described thread groove is arranged some pod apertures communicated with water conservancy diversion tract.
Further, described dilating catheter is provided with the part of thread groove for the tapered elliptic cone structure from rear end to front end, and the tip of dilating catheter is obtuse.
Further, the rear end of described dilating catheter is provided with two finger rings.
Further, the groove depth of described thread groove is 1-2mm, and the pitch of thread groove is 2-2.5mm.
Further, the outer wall of described dilating catheter is provided with indicating graduation.
Further, the end interface of described dilating catheter is the hickey suitable with female Luer, and described seam is provided with female Luer.
The screw thread dilator supplying lubricant provided by the invention, structure is simple, make, easy to use, the screw thread lines that lubricant can be made to be formed according to thread groove by the thread groove arranged lubricates expanded tract comprehensively, high lubricating effect, by the pod apertures modular design on dilating catheter end interface, inner water conservancy diversion tract and thread groove, conveniently can inject lubricant, the lubricant realizing not affecting operation technique constantly supplies, lubricant is flowed out by pod apertures, realizes continuous lubrication.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, 1, dilating catheter, 2, water conservancy diversion tract, 3, thread groove, 4, pod apertures, 5, finger ring, 6, interface.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
See Fig. 1, the screw thread dilator of the supplied lubricant of the embodiment of the present invention, comprise a dilating catheter 1, the end of dilating catheter 1 have interface 6 and in establish the water conservancy diversion tract 2 that communicates of interface 6 therewith, the end interface 6 of dilating catheter 1 is the hickey suitable with female Luer, interface 6 place is provided with female Luer, and female Luer can according to actual service condition choice for use list joint, twin adapter or three joints.The front end outer wall of dilating catheter 1 is arranged the thread groove 3 of water conservancy diversion, thread groove 3 is arranged some pod apertures 4 communicated with water conservancy diversion tract 2, pod apertures 4 is positioned at the trench bottom of thread groove, and lubricant can be evenly distributed on dilator surface along screw thread after flowing out.Dilating catheter is provided with the part of thread groove for the tapered elliptic cone structure from rear end to front end, and the tip of dilating catheter 1 is obtuse.The rear end of dilating catheter 1 is provided with two finger rings 5.The groove depth of thread groove 3 is 1-2mm, and the pitch of thread groove 3 is 2-2.5mm, and the thread groove on dilating catheter 1 has design 2 ~ 3 groups altogether, and the outer wall of dilating catheter 1 is also provided with indicating graduation.Because there is thread groove on this dilator surface, can not as plain cylindrical form dilator easy by urethra or ureter " locking " incarceration, if form locking and incarceration, due to the surface of helicitic texture, easily can be exited by rotating dilator, urethra mucous membrane of ureter can not be caused to damage even avulsion.
The screw thread dilator of the supplied lubricant of the embodiment of the present invention, can adopt metal material, medical macromolecular materials are made, and can add x-ray developing material in the material simultaneously.This can supply the screw thread dilator of lubricant, and structure is simple, makes, easy to use, and first at surface smear lubricant before using, the interface opened by end in use procedure again outer surface adds lubricant, the sufficient lubrication of expansion overall process.The screw thread lines that the present invention can make lubricant be formed according to thread groove by the thread groove arranged lubricates expanded tract comprehensively, high lubricating effect, by the pod apertures modular design on the end interface of dilating catheter, inner water conservancy diversion tract and thread groove, conveniently can inject lubricant, the lubricant realizing not affecting operation technique constantly supplies, lubricant is flowed out by pod apertures, realizes continuous lubrication.The surface of this dilator is also provided with indicating graduation simultaneously, and make to expand rear penetration depth clear and definite, degree of safety is higher.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
