Definitions

  • the invention relates to a surgical hand instrument referred to in the preamble of claim 1 Art.
  • Such a hand instrument is known from DE 20 2006 002 796 Ul.
  • the sleeve is formed in the known instrument as an insulating sleeve and serves to prevent any contact between the shaft tube and actuating rod a short circuit, since these are connected to the trained as a bipolar forceps hand instrument to different voltage poles.
  • the hand instrument is designed as a disposable instrument which is supplied sterile and disposed of after use, there are no problems with the sleeve located in the shaft tube.
  • the hand instrument if the hand instrument is to be reusable, then it must be completely cleanable and sterilizable, even on all inner surfaces.
  • Such an instrument can be easily cleaned and sterilized only when the sleeve is pulled out of the shaft tube. That is not always possible.
  • manual instruments with a curved shaft and rotatably arranged end effector disassembly for cleaning purposes is very difficult to achieve.
  • CONFIRMATION COPY In such difficult to disassemble hand instruments helps one so that for cleaning the shaft tube with cleaning and sterilizing liquids is rinsed longitudinally. For this purpose, a flushing connection is provided on the shaft tube.
  • the object of the present invention is to improve the cleanability of a generic hand instrument.
  • the sleeve is sealed at its ends against the wall, which it rests with a seal.
  • the adjacent wall may, as in the above-described prior art, be the inner wall of the shaft tube or the outer wall of the actuating rod, if the sleeve is to fit snugly.
  • the gap between the sleeve and the wall, which rests against the sleeve is thus sealed at both ends in this construction, so that nothing can penetrate into the gap, which would have to be cleaned or disinfected.
  • An only one-sided flushing the sleeve thus sufficient for proper cleaning and disinfection.
  • a seal at the ends of the sleeve is sufficient.
  • a full-surface bonding of the sleeve which would be much more expensive, is not required. It also simplify the assembly and disassembly.
  • the seal at the ends of the sleeve may be formed in different ways, for example as a ring bond, but is advantageous, according to claim 2, designed as a seated in a groove O-ring. This results in a simple construction, in particular a very easy way for assembly and disassembly.
  • the sleeve may, as in the aforementioned prior art, be formed as an insulating sleeve or advantageously, according to claim 3, as a sliding sleeve, which reduces the frictional resistance between the actuating rod and the shaft tube in contact.
  • This friction plays no role in straight shank, as shown in the prior art mentioned above, but in hand instruments with a curved shaft, as they have recently been increasingly used, especially in laparoscopy.
  • the actuating forces transmitted by the actuating rod such as e.g. Closing forces of a pair of pliers, lead to the fact that on a curved piece of the shaft, the actuating rod with great force is laid laterally against the shaft tube.
  • the sleeve according to claim 4 made of PEEK (Polyeti eretherketon) formed, a plastic with very low friction, which is characterized mainly by proven compatibility in the medical field.
  • the hand instrument according to the invention is advantageously produced according to claim 5, characterized in that first the sleeve is inserted into the still straight shaft tube and then the shaft tube is bent. This simplifies the production significantly.
  • Fig. 2 is a section along line 2 - 2 in Fig. 1 and
  • Fig. 3 is a section along line 3 - 3 in Fig. 2nd
  • Fig. 1 shows a hand instrument 1 according to the invention with an elongate, curved shaft tube 2 made of rigid material, e.g. Stole.
  • an end effector 3 is arranged, which has two mutually pivotally arranged branches, which form a pair of scissors or pliers depending on the training.
  • a handling unit 4 is arranged, which is actuated via movable grips 5 for actuating the end effector 3.
  • the end effector 3 is rotatably mounted to the shaft tube 2 with respect to the axis thereof and rotatably actuated by the handling unit 4 by means of a rotary ring 6.
  • Fig. 2 shows a cross section in the distal end region just before the end effector 3.
  • the actuating rod 7 is connected in a manner not shown in the handling unit 4 for actuation. In relative movement of the grips 5, the actuating rod 7 is moved longitudinally in the shaft tube 2.
  • the actuating rod 7 is in a manner not shown with the end effector 3 in engagement to adjust one or both of the branches of the end effector 3 relative to each other.
  • the actuating rod 7 is connected so that it causes a closing of the forceps or heavy industries at the end effector 3 upon retraction, ie when moving in the proximal direction.
  • the actuating rod 7 is preferably made of PEEK (polyetheretherketone) existing sleeve 8, which is formed in the embodiment with its outer wall of the inner wall of the shaft tube 2 fitting.
  • PEEK polyetheretherketone
  • it can also be designed to be in contact with the actuating rod 7.
  • the system of the sleeve 8 on the inner wall of the shaft tube 2 or the actuating rod 7 is so tight that a possible shift-safe hold arises, but the sleeve during assembly still in the shaft tube 2 can be inserted.
  • the sleeve 8 need not be formed over the entire length of the shaft tube 2, but may, for example, at the cut with the line 2 - 2 point of the shaft tube 2, ie shortly before the distal end, end, as shown in FIG.
  • the shaft tube 2 Since the shaft tube 2 is formed bent in the embodiment, it comes in power transmission via the actuating rod 7 to a system of the actuating rod 7 against the shaft tube 2. This system is prevented by the intermediate sleeve 8. This must therefore be present in particular at the bending points of the shaft tube 2.
  • the sleeve 8 prevents contact between the actuating rod 7 and the shaft tube 2. It can, with insulating training, avoid electrical contact, if, for example, as in the aforementioned prior art, the shaft tube 2 and the actuating rod 7 formed as an electrical conductor are connected to different voltages.
  • the hand instrument 1, which is very difficult to disassemble, for cleaning and disinfection is provided with a flushing connection 9, via which flushing fluid can be brought into the interior of the shaft tube 2.
  • the sleeve 8 ends at the proximal end of the shaft tube 2 at a distance from the flushing From there so rinsing liquid can penetrate into the annular space 10 between the actuating rod 7 and sleeve 8 and flow in this annulus to the distal end of the shaft tube 2 to flow out there through the end effector 3, which is still cleaned and disinfected.
  • the gap 11, between the shaft tube 2 and the sleeve 8 does not flow through, since the sleeve 8 in the exemplary embodiment, the shaft tube 2 fits tightly. In this gap 11 so can not be cleaned.
  • the invention therefore provides to seal the actuating rod 7 at its ends against the shaft tube 2 with a seal.
  • This is formed in the illustrated preferred embodiment as an O-ring 12, which is arranged in the illustrated annular groove of the sleeve 8.
  • the sleeve 8 closely engages the actuating rod 7, so the O-ring 12 receiving annular groove on the inside of the sleeve 8 would be arranged.
  • the end effector 3 on two mutually movable branches, which form a pair of pliers or scissors depending on the training.
  • One of the branches can also be fixed.
  • the end effector may also be integrally formed e.g. be formed as a surgical hook, which is longitudinally displaceable and rotatable by means of the actuating rod 7.
  • the end effector may be provided for use in high frequency surgery with one or more electrodes connected in mono- or bipolar to a high frequency generator.
  • the shaft tube 2 is best prepared in a straight shape and then bent after the sleeve was inserted into the first still straight shaft tube 2.
