Definitions
- the invention relates to a shaft of an endoscope according to the preamble of claim 1.
- Such a shaft is shown in US Pat. No. 5,151,101 A.
- the counterpart can be, for example, as shown in the cited document, the coupling cone of the main body of the endoscope. Also, e.g. for the coupling of an outer shaft to an inner shaft, this coupling can be used.
- a spring which biases the coupling piece in its transverse movement in the latching direction. This ensures a secure holder.
- the spring should not be made too strong, because otherwise the spring force to be overcome would be high and the operation would be generally difficult. However, if one chooses the spring force lower, so there is a risk that in case of unintentional touches of the coupling piece or vibrations shakes the locking engagement. If this happens during an operation, this can be unpleasant for all involved.
- the object of the present invention is to improve the safety of the latching engagement with a generic shaft of an endoscope with easy handling.
- a coupling device for suppressing the transverse movement can be brought into engagement locking device is provided on the coupling piece. This can be switched on and off, so that the coupling piece is locked or released. In the locked state, the transverse movement is prevented. A blocking with existing locking engagement thus ensures this completely, so that all uncertainties are avoided. It can be chosen a very weak spring, which is easy to use.
- the coupling piece is movable with respect to the longitudinal axis of one of the parts to be connected aligned transverse movement in one, the latching engagement releasing, or in one, the latching engagement locking position.
- the locking device necessary for unlocking or for releasing the locking engagement between the tail of the shank and the counterpart transverse movement of the coupling piece can be suppressed or blocked in the releasing position.
- the locking device is selectively operable in a locking position or in a release position, preferably by rotational movement of a coupling piece arranged on the handle part.
- any transverse movement of the coupling piece with the securing device can be suppressed or locked.
- the coupling piece can be mounted on the counterpart or on the tail and engage the other piece latching.
- the storage is carried out on the tail, as shown in the above-mentioned printed publication.
- the coupling piece is mounted to its transverse movement with a socket on a pin of the tail, as well as the above-mentioned document shows.
- the sleeve is used in rotatable design as a locking device, which results in constructive advantages.
- the coupling piece according to claim 4 may be mounted on a second pin, which has a switching member which can be brought into locking engagement. Again, this is a simple and effective solution to the lock problem.
- the coupling piece surrounds the tail ring, this is also a proven construction from the aforementioned document.
- Fig. 1 shows an axial section through a locking coupling according to the invention in
- Fig. 3 is a section along line 3 - 3 in Fig. 2nd
- FIGS. 1 to 3 show, in different views, a detent coupling 1, with which an end piece 2, which is fastened to the proximal end of a hollow shaft 3, can be coupled to a counterpart 4.
- the counterpart is for example part of the handle or of the main body of an endoscope, which is otherwise not shown, for example a resectoscope.
- the stem 3 is intended to be removable for replacement with a stem of another type or for cleaning purposes.
- the clutch should be easy and fast to use.
- the end piece 2 encloses a counterpart 4 open towards the cavity 5, which corresponds in its inner cross section to the outer cross section of the counterpart 4, which thus can be stored in the end piece 2 backlash after insertion in the direction of arrow 6 match.
- the counterpart 4 may for example also be hollow to allow passage into the shaft 3, or may carry instruments which are advanced into the shaft 3 during coupling.
- the counterpart 4 has on opposite sides projecting coupling pins 7 which engage in advancing in the direction of arrow 6 in parallel to the axis of the shaft 3 arranged to the proximal end open slots 8 in the side wall of the end piece 2.
- the coupling pins 7 extend beyond the slots 8 laterally beyond the outer surface of the end piece 2 and reach there into engagement with locking lugs 9, which are arranged on both sides outside of the slots 8.
- the latching lugs 9 are fastened on the inside of a coupling piece 10 that runs around the end piece 2 in an annular manner, as can be seen from FIG.
- Fig. 3 shows a view of the end piece 2 in the axial direction, seen in the insertion direction of the arrow 6. You can see the slots 8 and the locking lugs 9 and you can see the annular formation of the coupling piece 10 around the tail 2 around.
- the cross section of the locking coupling 1 is round. So it has the tail 2 and the coupling piece 10 round cross-section. Likewise, matching the counterpart has 4 round cross-section to fit into the cavity 5 of the end piece 2.
- the coupling piece 10 does not necessarily have to be formed as a closed ring. It can e.g. be designed as an interrupted ring with gap.
- the cavity has 5 parallel inner walls. However, these can also be conical. Then the counterpart 4 would be provided with conical outer walls. It would result in a construction similar to the above-mentioned document.
- the coupling piece 10 is mounted in the transverse direction, ie transversely to the axis of the shaft 3, on the end piece 2.
- a first pin 11 and a second pin 12 are attached to the end piece 2 opposite.
- On the first pin 11 is a sleeve 13 slidably mounted in the direction of the two pins.
- the sleeve 13 is, as shown in FIG. 1, mounted in the transverse direction fixedly mounted on the coupling piece 10, but it is rotatable about the common axis of the two pins 11 and 12.
- the bush 13 is provided in the illustrated embodiment with a toggle handle 15. At this can be attacked to rotate the sleeve 13, as indicated in Fig. 2 by the arrow 16.
- the toggle handle 15 also serves as a stop against a support 17 which is secured to the end piece 2.
- the second pin 12 is guided in a bore of the coupling piece 10, so that a two-sided clean leadership of the coupling piece 10 in the transverse direction, ie in the direction of the axis of the two pins 11 and 12 results.
- the latching lugs 9 are fastened on the inside of the coupling piece 10 and thus move with it. If the counterpart 4 is pressed into the cavity 5 of the end piece 2 in the direction of the arrow 6, then the coupling pins 7 move into the slots 8 and reach against the locking lugs 9, which can dodge towards the second pin 12 out together with the coupling piece 10 , In this case, the spring 14 is compressed. Have the coupling pins 7, the two locking lugs 9 overcome, then they can spring back under the force of the spring 14 and now secure the coupling pins 7 in the end of the slots 8. Thus, the locking engagement is secured. To release the coupling piece 10 is pressed with the locking lugs 9 in the direction of the second pin 12 by pressure on the top of the sleeve 13, so that the coupling pins 7 come free and the counterpart 4 can be removed.
- the latching engagement can also be carried out differently.
- the coupling piece 10 could be slidably mounted on the counterpart 4. On the coupling piece 10 could then be fastened inside the coupling pins 7.
- the locking lugs 9 would be fastened on the outside of the end piece 2.
- the lock can be locked.
- the sleeve 13 is brought to the toggle handle 15 in the position of FIG.
- the toggle handle 15 is then in the alignment of the support 17 directly above this, as shown in FIG. 1. If an attempt is then made to disengage the coupling, ie to move the coupling piece 10 in the direction of the second pin 12, the toggle handle 15 abuts against the support 17 and prevents this.
- the coupling is locked in locked position.
- toggle handle 15 is moved in the direction of arrow 16, as shown in Fig. 2. Then the toggle handle 15 is released from the support 17 and the coupling piece 10 can be moved freely for uncoupling.
- Fig. 1 an alternative embodiment of the locking locking device is additionally shown.
- On the second pin 12 a only schematically indicated by dashed line switching element 18 is arranged, which is switchable between a blocking and a non-blocking position.
- the switching member 18 projects laterally beyond the second pin 12 and prevents the required for unlocking movement of the Coupling piece 10 relative to the end piece 2.
- the switching member 18 is switchable such that it is completely removed or no longer protrudes laterally, so that the coupling piece 10 is freely movable again.
