Abstract

A receiving sleeve of a tool set includes a hollow body having an end face with an insertion opening for inserting a tool. The hollow body defines a longitudinal central axis and includes a plurality of inner clamping elements spaced apart in a circumferential direction. The clamping elements have punctiform or linear engagement sections at their free, radially inward protruding end portions. The engagement sections make force-fit and/or form-fit contact with the tool for holding the tool within the receiving sleeve at a radial distance from the hollow body. An inner side of the hollow body has circumferentially spaced rigid protrusions that extend axially in rib-like fashion. The inner clamping elements radially protrude further toward the longitudinal central axis of the hollow body than the rigid protrusions.

First claim

What is claimed:

1. A receiving sleeve of a tool set for a supporting mount of surgical tools, the receiving sleeve comprising a cylindrical hollow body, having an end face with an insertion opening for inserting a tool to be inserted, wherein the hollow body defines a longitudinal central axis and comprises a plurality of inner clamping elements spaced apart in a circumferential direction which have punctiform or linear engagement sections which are provided at their free, radially inward protruding end portions and adapted for making a force-fit and/or form-fit contact with said tool for holding said tool within the receiving sleeve at a radial distance from the hollow body, wherein an inner side of the hollow body is provided with a plurality of circumferentially spaced rigid protrusions which extend axially in rib-like fashion, wherein the inner clamping elements radially protrude further toward the longitudinal central axis of the hollow body than the rigid protrusions.

2. A receiving sleeve of a tool set for a supporting mount of surgical tools, the receiving sleeve comprising a cylindrical hollow body, having an end face with an insertion opening for inserting a tool to be inserted, wherein the hollow body defines a longitudinal central axis and comprises a plurality of inner clamping elements spaced apart in a circumferential direction which have punctiform or linear engagement sections which are provided at their free, radially inward protruding end portions and adapted for making a force-fit and/or form-fit contact with said tool for holding said tool within the receiving sleeve at a radial distance from the hollow body, wherein an inner side of the hollow body is provided with a plurality of circumferentially spaced rigid protrusions which extend axially in rib-like fashion, wherein the inner clamping elements radially protrude further toward the longitudinal central axis of the hollow body than the rigid protrusions, and wherein the hollow body comprises a plurality of radial openings as inflow openings for a cleaning fluid.

3. The receiving sleeve according to claim 2 , wherein the inner clamping elements are flexible and elastic clamping arms which extend in an axial direction and are formed on the hollow body as a hinge, wherein the radial openings are cut out in the hollow body in the circumferential direction between the clamping arms.

4. The receiving sleeve according claim 1 , wherein the receiving sleeve is formed in one piece.

5. The receiving sleeve according to claim 4 , wherein the inner clamping elements are made of metal and embedded or inserted in the hollow body of the receiving sleeve.

6. The receiving sleeve according to claim 1 , wherein the rigid protrusions form a catching bottom or stop on an end portion of the receiving sleeve opposite the insertion opening, said catching bottom or stop preventing said tool from being inserted too deeply in the receiving sleeve.

7. The receiving sleeve according to claim 1 , wherein a plurality of circumferentially spaced, rigid positioning studs are formed on the hollow body which extend axially beyond the end face of the receiving sleeve on an end portion of the hollow body opposite the insertion opening.

8. The receiving sleeve according to claim 1 , wherein an end portion of the hollow body opposite the insertion opening is provided with at least one further flexible and elastic latching protrusion or latching arm which extends axially beyond the end face of the receiving sleeve.

9. The receiving sleeve according to claim 1 , wherein the hollow body is provided in an axial area of the insertion opening with an annular protrusion or collar serving as an axial stop for the receiving sleeve.

10. The receiving sleeve according to claim 9 , wherein the annular protrusion or collar comprises axially extending protrusions on its side facing axially away from the insertion opening, which serve as punctiform or linear axial supports or spacers.

11. The receiving sleeve according to claim 1 , wherein the rigid protrusions are chamfered like a funnel in an area of the insertion opening, producing an insertion aid for said tool.

12. A receiving sleeve of a tool set for a supporting mount of surgical tools, the receiving sleeve comprising a cylindrical hollow body, having an end face with an insertion opening for inserting a tool to be inserted, wherein the hollow body defines a longitudinal central axis and comprises a plurality of inner clamping arms spaced apart in a circumferential direction which have punctiform or linear engagement sections which are provided at their free, radially inward protruding end portions and adapted for making a force-fit and/or form-fit contact with said tool for holding said tool within the receiving sleeve at a radial distance from the hollow body, wherein the clamping arms are interconnected with each other to form an insert made of metal which insert is a component separate from the hollow body, the insert being inserted in the hollow body which is made of plastic material, wherein an inner side of the hollow body is provided with a plurality of rigid protrusions spaced apart in the circumferential direction and which extend axially in a rib-like fashion, wherein the clamping arms of the metallic insert arrange themselves between the rigid protrusions as seen in the circumferential direction when the metallic insert is inserted into the hollow body.

13. The receiving sleeve according to claim 12 , wherein the metallic insert has an annular bottom from which the clamping arms extend substantially perpendicularly to the bottom.

14. The receiving sleeve according to claim 13 , wherein a respective retaining bracket is formed between the clamping arms as seen in the circumferential direction which extends substantially perpendicularly to the bottom in a same direction as the clamping arms.

15. A surgical tool set for storing and cleaning surgical tools, the tool set comprising a reception box that includes a side frame, a bottom part and an intermediate shelf which can be placed in the reception box, wherein the bottom part and/or the intermediate shelf comprises a first perforated plate and a second perforated plate, the first and second perforated plates being parallel to one another, spaced and interconnected, each of the first and second perforated plates forming an axially aligned hole array, and a cover for closing the reception box, the tool set further comprising a plurality of receiving sleeves according to claim 1 that are inserted in the hole arrays.

16. The surgical tool set according to claim 15 , wherein the reception box and the cover are faulted from a perforated material.

17. The surgical tool set according to claim 15 , wherein the first perforated plate has round holes and the second perforated plate has cornered holes such that the receiving sleeves can be inserted or are inserted at their hollow bodies into the round holes.

18. The surgical tool set according to claim 17 , wherein at least one latching arm engages behind the second perforated plate when one of the receiving sleeves is axially inserted to a full extent, whereby said one of the receiving sleeves is axially fixed in the intermediate shelf by the cooperation between a collar formed on said one of the receiving sleeves and the latching arm.
