Definitions

  • the present invention relates to a surgical instrument according to the preamble of claim 1 and to a method for disassembling the surgical instrument.
  • the object of the invention is to improve the sliding shaft instruments from the prior art, in particular the object of the invention is to improve a generic surgical instrument in such a way that the handling is simplified, is improved by the sterilization and the mechanical design is simplified.
  • the object is achieved with a surgical instrument according to claim 1 and a method claim for disassembly of this surgical instrument.
  • the surgical instrument according to the invention is preferably a sliding-shaft instrument which can have various functional elements.
  • the functional element is the element actuated by the sliding-shaft instrument, wherein forceps or cutting elements are particularly preferably used as functional elements.
  • connection between the shaft and sliding part is preferably designed via rails or grooves.
  • the sliding part can be moved horizontally to the shaft by moving the handles and on the other hand, the sliding part can be released from the shaft, wherein the sliding part remains connected to the functional element.
  • the surgical instrument has a locking lug and a spring, wherein the latch is integrally formed.
  • the spring effect is achieved, inter alia, a bow shape. This form describes a half to three-quarter circle.
  • the one-piece construction has the advantage that a cleaning can be carried out in a simplified manner.
  • a corresponding disassembly of the surgical instrument is simplified by the one-piece locking.
  • the latch is located in the handle which is received in the other handle.
  • the lock in the corresponding receptacle on a thickening which cooperates with a stop, which in turn is formed on the handle. This should advantageously prevent one hand, that the handle is unintentionally overrun.
  • a preferred embodiment of a coupling which consists of a nose and a recess. It should be irrelevant whether the nose is formed on the lock and the corresponding recesses on the handle or whether the nose is formed on the handle and corresponding recesses are formed in the lock.
  • the advantage here is that the lock can be engaged by means of the coupling and controlled accordingly.
  • the locking has a profiling for manual operation.
  • This profiling is used for easier actuation of the lock just in relation to the coupling.
  • a flattened axis is also arranged in a connecting part, which cooperates with a slot which extends into the connecting part handle.
  • the advantage here is that the slot releases the flattened axis only in a certain angular position. This makes it easy to remove the handle from the connector.
  • a slot in the connecting part and a flattened axis is provided on the handle to be removed. It is also preferred that the slot is arranged on the handle to be removed and the flattened axis between two flanks of the connecting part.
  • the advantage here is the easy removability of the handle at a predetermined angular position.
  • FIG. 1 shows a side view of a surgical device according to the invention
  • Instruments in working position shows a side view of the surgical instrument of Figure 1 according to the invention in a rest position; shows the surgical instrument of Figures 1 and 2 according to the invention in a sectional side view; shows an enlarged view of a part of Figure 3; shows a plan view of an inventive surgical instrument of Figure 2; and shows another side view of a surgical instrument according to the invention.
  • FIG. 1 shows a side view of an embodiment of a surgical instrument according to the invention, namely an arthroscopic forceps 1.
  • the arthroscopic forceps 1 has a part 19 which comprises a handle 3, a connecting part 7 and a shaft 4.
  • a handle 2 is shown.
  • a functional element 6 is shown in the working position.
  • the connecting part 7 is arranged between the shaft 4 and the handle 3.
  • a functional element 6 is shown in the working position on the shaft 4 and the sliding part 5.
  • the connecting part 7 is between the shaft 4 and the handle 3.
  • a profiling 8, and a flattened axis 9 and a slot 10 can be seen.
  • the slot 10 is embedded in the connecting part 7.
  • the flattened axis 9, however, is integrally formed on the handle 2.
  • the connecting part 7 in this case has two flanks 18, 19 in the upper region, which can be seen from the top view in FIG. Between these two flanks 18, 19 parts of the handle 2, the shaft 4, the sliding part 5 and a lock 11 are attached.
  • the handle 2 is partially rotatably mounted in a recess of the part 17. The rotational movement of the handle 2 is limited by the latch 11 and corresponding stop points on the handle 3.
  • FIG. 2 shows a partially sectioned view of Figure 1 in a rest position. Again, the handles 2, 3 can be seen, and these are now closer to each other than in Figure 1 and thus cause the functional element 6 is pushed to rest. This happens by a relative movement of the sliding part 5 to the shaft 4th
  • the connecting part 7 is shown partially cut in Figure 2. Due to the sectional view of the connecting part 7 is now easy to see how the lock 11 is arcuately arranged between the two flanks of the connecting part 7 and partially guided in the handle 2. This locking 11 in this case comprises the profiling 8, as well as the locking lug 12.
  • FIG. 3 now shows an overall sectional view of FIG. 2. In addition to the handles 2, 3, the functional element 6, which is in the rest position, and the shaft 4 and the sliding part 5 are again closed detect. In addition, an area consisting of parts of the handles 2, 3, the connecting part 7, as well as the lock 11 is encircled by a circle C.
  • FIG. 4 shows how the latch 11 on the one hand via the locking lug 12 influence on the sliding part 5 and on the other hand during the rotational movement of the handle 2 to handle 3 holds the handle 2 in its position and next due to its counteracting force an accidental Sliding out of the handle 2 over the formed in the connecting part 7 slot 10 on the flattened axis 9 of the handle 2 prevented.
  • FIG. 6 shows the arthroscopic forceps 1, wherein the handle 2 has been pulled towards the handle 3 until the slot 10 releases the flattened axis 9 of the handle 2.
  • the lock 11 not shown, was first pressed by the handle 2, which was pulled to the handle 3 towards the end 13 of the sliding part 5.
  • the flattened axis 9 releases and the handle 2 can be pulled down, the latch 11 can be further pushed into the handle 2, in turn, the flattened end 13 of the sliding part 5 is released , The released end 13 is then held by a bracket 20 within a predetermined range of motion held pivotally about a rotation axis 21.
