Detailed description of the invention
This utility model is further illustrated below in conjunction with Figure of description.
A kind of two segment Flexible ureteroscope sheath pipe inserted of looking at straight includes sheath body 1, sheath body 1 includes leading portion sheath pipe 101 and the back segment sheath pipe 102 of socket cooperation, in specifically leading portion sheath pipe 101 is socketed in back segment sheath pipe 102, and leading portion sheath pipe 101 can stretch in back segment sheath pipe 102.While leading portion sheath pipe 101 and the socket of back segment sheath pipe 102, leading portion sheath pipe 101, near one end of back segment sheath pipe 102 and back segment sheath pipe 102 inwall snap-fit engagement, makes both be relatively fixed.The mechanism of snap-fit engagement can use multiple, as leading portion sheath pipe 101 is arranged to bell mouth shape structure 1011 etc. near one end of back segment sheath pipe 102.In order to prevent leading portion sheath pipe 101 near back segment sheath pipe 102 movement operationally, back segment sheath pipe 102 is symmetrical arranged two horizontal recessed marks 1021 to inner chamber depression on the tube wall of leading portion sheath pipe 101 one end, arranges a recessed mark of longitudinal direction 1022 to inner chamber depression in the middle part of described back segment sheath pipe 102.In order to coordinate the use of ureterscopy, sheath body 1 is equipped with the closure stopper 2 that can eliminate ureterscopy with leading portion sheath pipe 101 head end space.
Flexible ureteroscope sheath pipe is divided into F12/F10, F14/F12, F16/F14, the most frequently used model to be F14/F12 according to caliber difference.This utility model is unisex type.In order to make those skilled in the art more can be appreciated that the technical solution of the utility model, this utility model illustrates this utility model specific embodiments as a example by F14/F12-450mm type.
As shown in Figure 1 to Figure 3, this utility model sheath body 1 is made up of leading portion sheath pipe 101 and back segment sheath pipe 102, and sheath body 1 is the most cylindrical, and sheath body 1 appearance is arranged with li a length of unit scales mark.The a length of 420mm of leading portion sheath pipe 101, in leading portion sheath pipe 101 main body, footpath, periphery is respectively 12mm and 14mm, and leading portion sheath pipe 101 tail end is bell mouth shape structure 1011, is about 10mm, and footpath, bell mouth shape structure 1011 periphery is 15mm.The a length of 40mm of back segment sheath pipe 102, in its main body, footpath, periphery is respectively 15.5mm and 17.5mm, and in back segment sheath pipe 102 head end, footpath, periphery is respectively 14.5mm and 16.5mm, is about 10mm.Back segment sheath pipe 102 tail end opening inner circumferential footpath 15.5mm.Back segment sheath pipe 102 head end tube wall at its head end opening 11mm is symmetrical arranged two horizontal recessed marks 1021 prominent to inner chamber, arranges a recessed mark 1022 of the longitudinal direction prominent to inner chamber in the middle part of back segment sheath pipe 102, longitudinally the long 15mm of recessed mark.When present segment sheath pipe 101 is inserted in back segment sheath pipe 102 and is in complete straight configuration, the bell mouth shape structure 1011 of leading portion sheath pipe 101 can be with horizontal recessed mark 1021 snap-fit engagement, and when horizontal recessed mark 1021 and longitudinal recessed mark 1022 can stop operation technique, leading portion sheath pipe 101 is unexpected in back segment sheath pipe 102 shrinks.
After leading portion sheath pipe 101 and the socket of back segment sheath pipe 102 coordinate, active length during sheath body 1 fully collapsed condition is that 420mm, now back segment sheath pipe 102 and leading portion sheath pipe 101 are completely overlapped；During sheath body 1 fully extended state, deducting and be connected the sheath length of tube 10mm coordinated with leading portion sheath pipe 101 tail end, its active length is 450mm.
The tube wall of leading portion sheath pipe 101 and back segment sheath pipe 102 includes inner wall layer and outer wall layer, and between its inner wall layer and outer wall layer, helical form arranges very thin steel wire to strengthen inner chamber steadiness.Leading portion sheath pipe 101 and the inner wall layer of back segment sheath pipe 102 and outer wall layer surface configuration hydrophilic coating, to reduce the frictional force of operative process mesotheca tube wall and ureter inwall.
This utility model is also independently arranged closure stopper 2.Closure stopper 2 is in tapered tube shape, and long 15mm, outer wall surface arranges hydrophilic coating；After closure stopper 2 is inserted in F7.5/F8.0 ureterscopy head end, it is inserted in from sheath body 1 (contraction state) inner chamber, adjust closure stopper 2 in F7.5/F8.0 ureterscopy head-end location, sheath body 1(leading portion sheath pipe 101 can be closed) space between head end inner chamber and F7.5/F8.0 ureterscopy, insert offer for direct-view under scope convenient.
The each parts of this utility model can be selected for the medical plastic manufacture of corresponding different hardness.
The using method that this utility model direct-view is inserted:
After anaesthetizing successfully, take calculi position.If male patient, it is used alone sheath body 1, sheath body 1 is adjusted to fully collapsed condition；Closure stopper 2 is inserted about 15mm from ureterscopy head end, again ureterscopy is inserted from sheath body 1 inner chamber, and adjust the position of closure stopper 2, now the head end of ureterscopy exposes sheath body 1 inner chamber about 10mm, bladder is entered from urethra under being looked at straight together with sheath body 1 by ureterscopy, under zebra guide wire guides, under being looked at straight together with ureterscopy by sheath body 1, insert renal pelvis.Retain sheath body 1 and seal wire, ureterscopy is slowly exited together with closure stopper 2；The sheath body 1 being in fully collapsed condition is stretched to complete straight configuration；Insert Flexible ureteroscope from sheath body 1 inner chamber first inserted, complete Ho.YAG laser lithotripsy.Female patient operation method is essentially identical with male patient, except that in operation process, sheath body 1 is in fully collapsed condition all the time.
Finally illustrate is that above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent, without deviating from objective and the scope of technical solutions of the utility model, it all should be contained in the middle of right of the present utility model.
