EXTENSION FOOT SLEEVE

Abstract

An extension foot sleeve is formed with an L-shaped foot-receiving shell having an external adapter block for arranging on an operating table and having quick-release clasps and detent tabs for securing a patient's foot. The foot sleeve makes it possible to easily clamp a patient's foot without turning it in the L-shaped foot-receiving shell and without moving cushioning material laterally, and also reliably prevents an accidental release of the quick-release clasps or undesirable contact between the operating team and same. The quick-release clasps are arranged in pairs to the right and left on side edges of the foot-receiving shell in an edge region of the L angle close to the heel and in an edge region of the upper end of the foot-receiving shell. The extension foot sleeve is associated with clamps having detent tabs on both sides, which can be inserted in parallel into the quick-release clasps.

Claims

1-7. (canceled)

8. An extension foot sleeve, comprising: an L-shaped foot-receiving shell having side edges and an external adapter block disposed close to a heel, for arrangement on an operating table; latching tabs for securing a foot of a patient; quick-release clasps disposed in pairs on both a left-side and a right-side of said side edges of said L-shaped foot-receiving shell in a first edge region of a L angle of said L-shaped foot-receiving shell close to the heel and in a second edge region at an upper end of said L-shaped foot-receiving shell for receiving a calf; and clamping brackets having said latching tabs on both sides, said latching tabs being inserted in parallel into said quick-release clasps and can be locked therein.

9. The extension foot sleeve according to claim 8, further comprising base blocks for securing said quick-release clasps in one piece to said L-shaped foot-receiving shell, said base blocks are formed integrally on said L-shaped foot-receiving shell in a region of said quick-release clasps.

10. The extension foot sleeve according to claim 8, wherein said quick-release clasps have fastening means and said quick-release clasps are each disposed with angle adjustability on said L-shaped foot-receiving shell by said fastening means that are guided by a pivot axis.

11. The extension foot sleeve according to claim 8, wherein: said L-shaped foot-receiving shell has latching recesses formed therein; and said quick-release clasps each have latching lugs directed toward said L-shaped foot-receiving shell, said latching lugs engage in said latching recesses in or on said L-shaped foot-receiving shell, said latching recesses either correspond to a width of said latching lugs or are configured as part-circle recesses which are longer than said latching lugs are wide.

12. The extension foot sleeve according to claim 9, wherein said L-shaped foot-receiving shell is produced in one piece with said base blocks for said quick-release clasps and with a further base block for said external adapter block, by a 3D printing method.

13. The extension foot sleeve according to claim 8, wherein said latching tabs are disposed at two free ends of said clamping brackets being U-shaped clamping brackets.

14. The extension foot sleeve according to claim 13, wherein each of said clamping brackets has a connection tab between said latching tabs, said connection tab is configured as an ergonomically widened contact face.

Description

[0012] An illustrative embodiment of the invention is described in more detail below with reference to the drawings, in which:

[0013] FIG. 1 shows a three-dimensional view of an extension foot sleeve, and

[0014] FIG. 2 shows an exploded view of the extension foot sleeve from FIG. 1.

[0015] The extension foot sleeve is formed from an L-shaped foot-receiving shell 1 having an adapter block 13 close to the heel, for arrangement on an operating table, and having quick-release clasps 2 and latching tabs 3, wherein the latching tabs 3 are arranged at the free ends of U-shaped clamping brackets 14, which have a connection tab 17 between the latching tabs 3, which connection tab 17 has an ergonomically widened contact face in relation to the width of the latching tabs 3.

[0016] On both sides of the foot-receiving shell 1, base blocks 5 are formed integrally on the material of the foot-receiving shell 1 in the region near the heel or in the angle region of the L-shaped foot-receiving shell 1, and base blocks 4 are formed integrally on the material of the foot-receiving shell 1 in the lower calf region, which blocks are provided for the arrangement of the quick-release clasps 2 and have a through-opening via which a fastening means in the form of a spacer sleeve nut 9 can be inserted, with which the quick-release clasps 2 can be secured firmly or adjustably in terms of their angle.

[0017] The upper base block 4 has a narrow latching recess 6 into which a latching lug 10 of the quick-release clasp 2 extends, such that the latter is substantially limited in terms of its angular movement, whereas the base block 5 in the heel region of the foot-receiving shell 1 has an elongate latching recess 7 which is directed about the pivot axis 8 and which is very much wider than the latching lug 10 of the associated quick-release clasp 2, such that the latter can be pivoted about the pivot axis 8 in a defined angle range.

[0018] To secure a patient's foot, the clamping brackets 14 can first of all be pushed into the openings of the quick-release claps 2, whereupon the closure of the tension levers of the quick-release clasps 2 has the effect that the latching tabs 3 of the clamping brackets 4 are pulled still tighter against a patient's foot, wherein the tension levers can advantageously also have an additional ratchet function.

[0019] A base block 12 for the arrangement of an adapter block 13 on the foot-receiving shell 1 is integrally formed under the heel region of the foot-receiving shell 1, having an unlocking knob 15 for the manual assembly and disassembly of the extension foot sleeve on an operating table.
