616.672 12/1898 Kelling 128/8 944.830 12/1909 Sussmann 128/8 9 Clalms, 3 Drawing Flgures l2 3 l 2(2 l STILET FOR ENDOSCOPES BACKGROUND OF THE INVENTION This invention relates to a stilet to be inserted in an endoscope for adjusting the flexibility of the endoscope to assist in smooth insertion of the scop into the cavity of a human body.
In recent years, the development of an endoscope has been remarkable in permitting the device to be inserted through the mouth as far as the stomach, duodenum and the small intestine, and through the anus as far as the rectum, sigmoid colon, descending colon, transverse colon and the ascending colon, for medical observation of these organs.
It is required than an endoscope operative for deep observation be sufficiently flexible and bendable so that the forward end thereof may smoothly reach a position of predetermined depth. It has heretofore been difficult to insert the device deeply because of the fact that it tends to be unnecessarily bent concentratedly at a relatively shallow portion of the human body such as the stomach to disturb advancement of the forward end of the device or because of its insufficient overall available length.
In an attempt to obviate this defect, a device has been proposed in which the flexibility of the flexible tube of the endoscope is progressively varied in such a manner that the tube is made relatively soft at its forward end and is made gradually harder at portions closer to the operation section. The endoscope of the arrangement in which the rigidity or flexibility of the tube is predetermined does not assist' to positively solve the above problem. The defect may be eliminated if the flexibility of the flexible tube is made adjustable, but with the prior art device, the construction of the tube to make it adjustable becomes complex, thereby resulting in a tube of an inconveniently increased diameter.
SUMMARY OF THE INVENTION Accordingly the object of the invention is to provide a stilet of simple construction and capable of being externally operated to optionally adjust the flexibility of a flexible tube of an endoscope by being inserted into the endoscope prior to the insertion of the device into the cavity of a human body.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a cross sectional elevation of a stilet embodying this invention;
FIG. 2 is a cross section taken along the line 22 in FIG. 1; and
FIG. 3 is a schematic view illustrating an endoscope employing the stilet of FIG. 1 as being in an operative inserted position.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION bore 13. The connecting ring 14 is attached to an adjusting cylinder 15 at its rear end so that the central bore 13 of the former is coaxially connected to the central bore of the latter. On the upper side of the front half portion of the adjusting cylinder 15 there is formed a row of triangular teeth 16 along the longitudinal direction thereof. On the lower side of the rear half portion of the adjusting cylinder 15 there is perforated a long slit 17 extending along the longitudinal direction and communicatingwith the central bore thereof. The triangular teeth 16 each may be in the shape of a rightangled triangle with the hypotenuse and vertical side respectively corresponding to the front and rear sides of the tooth. A sliding ring l8is fitted on the periphery of the adjusting cylinder 15 so as to slide along the rear half portion thereof. From the upper outer side of the ring 18 there is radially extended a projection 20 with its forked top portion forming a bearing 19. On the lower inner side of the ring 18 there is fixed a supporting plate 21 (see FIG. 2) extending into the central bore through the slit 17 of the adjusting cylinder 15. By means of this supporting plate 21, the sliding ring 18 may be supported on the adjusting cylinder to be slidable therealong without rotation of the sliding ring 18. A retracting vwire 22 is inserted through the central bores of the coil spring 11, connecting member 14 and adjusting ring which are'arranged in a coaxial relationship. The wire 22 is connected to the rear end of the guide member 12 and the forward side of the supporting plate 21 at its both ends to be stretched therebetween.
A lever 26 is rockably supported on the bearing 19 of the projection 20 by means of a pin 23. On the forward lower side of the lever 26 there are formed a plurality of teeth 24 engageable with the teeth 16 of the adjusting cylinder 15. The rear portion of the lever constitutes a handle 25. Between the sliding ring 18 and lever 26 there is connected a wire spring 27 so that, in the normal condition, the lever 26 is urged in the rotating direction of an arrow a to allow the teeth of the lever 26 to engage the teeth of the adjusting cylinder 15 thereby preventing the sliding of the sliding ring 18 in the backward direction by the coil spring 11.
With the stilet constructed above, when the sliding ring 18 is slid against the adjusting cylinder 15, so that the teeth 24 of the lever 26 pivoted on the sliding ring 18 are engaged with the extremely forward portion of the row of teeth, the retracting wire 22 takes the most loose condition in which the coil spring 1 l is most flexible. In this situation, as the sliding ring 18 is moved rearwards along the adjusting cylinder 15, the clearance between the adjacent turns of coil spring 11 is gradually made shorter, that is the coil spring is compressed to decrease its flexibility. When the desired flexibility is obtained, the ring 18 is stopped, so that its flexibility is maintained due to the engagement of the teeth of the lever 26 and adjusting cylinder 15. Alternatively, if it is desired to increase the flexibility of the coil spring 11, the lever 26 is rocked by operating the handle 25 to release the engagement of the teeth 16 and 24 so that the sliding ring 18 may be retracted forwards by the coil spring 11.
In the using of the stilet, the coil spring of the stilet is inserted into the flexible tube 30 of an endoscope from its forward end, thereby being located in the flexible tube in a substantially coaxial relationship there with as shown in FIG. 3. Then, the endoscope is inserted. into the deep portion of the cavity of the human body while the flexibility of the coil spring and thus the flexible tube 30 is adjusted by operating the lever outside the human body. Accordingly, the insertion of the flexible tube of the endoscope whose flexibility is adjusted as the endoscope is deeply inserted prevents the flexible tube from the unnecessarily concentrated bending in a cavity located on the way to the observed portion.
