[0062] The first surgical tool 10 according to the invention shown in FIG. 1 comprises a surgical clamp 20 with two legs 21 and a base 22 connecting the legs. A handle 30 is connected to the base 22 via two predetermined breaking points 91. The first predetermined breaking points 91 are recessed with respect to a boundary surface of the base 22 facing the handle 30.

[0063] The tool 10 further comprises a drilling aid 40 with two openings 41. The drilling aid 40 is connected to the handle 30 via a second predetermined breaking point 92. The openings 41 of the drilling aid have a distance D which is greater than the distance d of the legs 21 of the clamp 20. Furthermore, in this embodiment, the drilling aid 40 of the tool 10 has a separation opening in the form of two separation slots 42. In alternative embodiments according to the invention, a separation opening could also be formed in another element of the one-piece tool 10. The drilling aid 40 further comprises a bending region 44 disposed between an opening region 45 containing the openings 41 and a slot region 46 containing the separation opening. The drilling aid 40 further comprises an impact notch 43 for impacting the clamp 20 separated from the handle 30 into a bone. The impact notch 43 is arranged at a second end 33 of the handle 30 opposite a staple receiving portion 31. The functions of the separation slot 42, the bending portion 44, and the impact notch 43 will be explained in further detail below.

[0064] The tool 10 further includes two drills 50 that are connected to the handle 30 at respective first ends 51 via third predetermined breaking points 93 (see also FIG. 5). The drills 50 have a respective first drill tip 53 at their ends 51, the third predetermined breaking points 93 being spaced apart from the first drill tips 53. At their respective second ends 52, the drills 50 are connected to the drilling aid 40 via fourth predetermined breaking points 94. Also at their respective second ends 52, the drills 50 have a respective second drill tip 54, the fourth predetermined breaking points 94 being spaced from the second drill tips 54.

[0065] The clamp receptacle 31 is formed as a recess formed at a first end 32 of the handle 30. The function of the recess is also explained below.

[0066] To use the tool 10, the drilling aid 40 can be separated from the handle 30 at the second predetermined breaking point 92 in a first step. Preferably, the drills 50 are also separated from the handle 30 at the third predetermined breaking point 93, while they initially remain connected to the drilling aid 40 at the fourth predetermined breaking point 94. Alternatively, when separating the drilling aid 40 from the handle 30, the drills 50 can be separated from the drilling aid 40 at the fourth predetermined breaking points 94, while the drills 50 initially remain connected to the handle 30 via the third predetermined breaking points 93.

[0067] After the drilling aid 40 has thus been separated from the handle 30, the legs 21 of the clamp 20 still connected to the handle 30 can be inserted into the separation slots 42 so that the first predetermined breaking points 91 come to lie adjacent to the separation slots 42. By bending the handle 30 and the clamp 20 still connected thereto, the clamp 20 can be separated from the handle 30 at the first predetermined breaking points 91 in a clean and controlled manner. Due to the arrangement of the predetermined breaking points 91 at the base 22, sharp breaking edges occur at most on the sides facing away from the legs 21.

[0068] Before or after separating the clamp 20 from the handle 30, the drill aid 40 may be used in a manner known per se to define the positions of two holes in two regions of a bone (e.g., over a fracture or in two bones over a joint to be fused). If necessary, the drill guide 40 can be bent in the tapered bending region 44 to allow accessibility. The holes can be made using the drills 50 separated from the handle 30 and the drill aid 40.

[0069] The clamp 20 separated from the handle 30 can then be clamped with its base in the recess 31 of the handle 30 and thus held in a force-fit and/or form-fit manner. The recess 31 serves as an anti-slip device when tapping in. The two legs 21 of the clamp can then be inserted into the holes made in the bone. The drive-in notch 43 allows the clamp 20 to be driven carefully into the bone, bringing it even closer to the bone.

[0070] FIG. 2 shows a second surgical tool 10′ according to the invention, which is also formed in one piece. It contains the following elements, which are connected to each other via predetermined breaking points 95: [0071] a surgical drilling aid 140 with two openings 141; [0072] a surgical scalpel 60 having a blade 61; [0073] a sliding aid 80 with two openings 81; [0074] a scale 71; [0075] a wand 70.

[0076] The drilling aid 140 includes a handle 145 and a tab 141 connected thereto. The tab 141 includes a central portion 142 from which a rectangle 143 projects laterally, and two end portions 144, each of which includes one of the apertures 141. For use, the rectangle 143 and the end regions 144 are each folded 90° to the same side. The protruding rectangle 143 is used as a stop for the end regions 144. Thus, the two openings 141 are axially aligned facing each other. A drill can then be pushed axially through both openings 141 and guided in this way.

[0077] The sliding aid 80 has a handle 85 and a tab 81 connected thereto. The tab 81 contains a central area 82 and two end areas 84, each of which contains one of the openings 81. For use, the end portions 84 are each folded 90° to the same side. Thus, the two openings 81 are axially aligned opposite each other. The wand 70 is then slid through the aligned apertures 81. To measure the depth of a hole drilled in a bone, the wand 70 is slid into the hole. Then the sliding aid 80 is slid to the stop. The construct is thus held, pulled out of the hole and held against a scale 71 arranged on the tool 10′ and read. In this way, the depth of the hole can be determined.

[0078] The tool 10′ may be designed for one or more specific indications and have the necessary and suitable elements for this purpose, which can be separated and used by cutting them off at the predetermined breaking points.

[0079] FIG. 3 shows an alternative embodiment of the tool from FIG. 1. The differences compared to the embodiment according to FIG. 1 are explained below. Instead of two separation slots, only one separation slot 42 is provided, which has a width that corresponds approximately to the width of the clamp 20. Furthermore, the clamp 20 has a beveled base 22 which runs at an angle α of approximately 25°.

[0080] FIG. 4 shows an enlarged view of section A of FIG. 1. The predetermined breaking points 91 are recessed in a recess 24 in the base 22 on the side 23 facing the handle.

[0081] FIG. 5 shows an enlarged view of the section B of FIG. 1. The drills 50 have a shank 55 and a wedge-shaped section 56 at the first end 51. The wedge-shaped section 56 runs from the shank 55 into the drill tip 53. The predetermined breaking points 93 are arranged at a distance from the drill tip 53, adjacent to the transition between the shank 55 and the conical section 56. This arrangement of the predetermined breaking points 93 is advantageous, since an arrangement in the shank 55 would produce a larger hole due to burrs, and an arrangement at the tip would lead to running of the drill 50.

[0082] FIGS. 6a and 6b show a first arm 101 and a second arm 102 for a compression clamp 100 (see FIG. 6c). In each of FIGS. 6a and 6b, a flat blank is shown on the left side and a curved shape of the blank is shown on the right side.

[0083] The first arm 101 has a pin 103 pressed to the blank 101. The blank 101 also has a recess 105 for receiving the bent second arm 102 (see FIG. 6c). Furthermore, openings 106 are provided for receiving a K-wire. The blank for the first arm 101 is bent along a central axis M to form a U-shaped cross-section. The blank may be provided flat or in a pre-bent form. Similarly, the pin 103 may be provided pre-bent, separately or as a separable part on the tool 10.

[0084] FIG. 6b shows a blank for the second arm 102. The second arm 102 is provided with two openings 104 through which the pin 103 can be guided. Openings 106 are also provided in the second arm. The second arm is also bent (see FIG. 6b, right) along a central axis M to form a U-shaped cross-section. By assembling the first arm 101 and the second arm 102, the compression forceps 100 shown in FIG. 6c are formed. To do this, the second arm 102 is inserted through the recess 105 and placed on the pin 103.

[0085] FIG. 6d shows a K-wire 107. The K-wire 107 is cut out of a sheet by 3D laser cutting or produced by additional milling, grinding or pressing of a laser-cut part. Three-dimensional tips 108 can be formed at the same time.

[0086] FIG. 7 shows an alternative embodiment of a compression forceps 110, which is constructed from a first arm 111 and a second arm 112. The first arm 111 and the second arm 112 are pivotally connected to each other via a pin 113, which is pressed or bent out and countersunk into the first arm 112. The first arm 111 and the second arm 112 are both fabricated as flat blanks from a sheet metal. The second arm 111 has a guide track 115 along which a stop 114 of the second arm 112 can be guided. The first arm 111 and the second arm 112 have bent sections 118 which form a handle. A compression head 117 is formed at an end remote from the handle 118. The compression head 117 includes apertures 116 and slot-shaped apertures 119. The slot-shaped openings 119 (similar to slot-shaped openings 119 in the area of the handle 118) serve to facilitate bending.

[0087] FIGS. 8a to 8f show various configurations of a handle 120 for a screwdriver. The handle 120 is formed from a flat blank. FIG. 8a shows the flat blank for the handle 120. The blank has a connecting region 122 from which three arms 121 extend in a star shape. Slots between the connecting region 122 and the arms 121 facilitate bendability. End regions 123a, 123b and 123c are arranged at the ends of the arms 121, which form an interface in the assembled handle 120 for receiving a blade 125 (see FIG. 8f).

[0088] FIG. 8b shows the blank from FIG. 8a with individual, bent elements in the area of the end regions 123a, 123b and 123c.

[0089] To form the handle 120, the arms 121 are bent by 90° so that a three-dimensional body is formed (see FIG. 8c). An interface 124 for the blade 125 is formed by the bent parts in the end regions 123a, 123b and 123c. A guide opening 129 is used to receive the shank of the blade 125. An anti-rotation opening 127 is used to receive an out-of-round portion of the blade 125 for transmitting torque. An end stop 128 defines an axial end position for the blade 125. Two inwardly directed projections form an axial retainer 126, in which the blade 125 can positively engage with a constriction.

[0090] FIG. 8d shows the handle 120 with the blade 125 inserted. After inserting the blade, the last arm (here the arm with the end piece 123a) is bent into an end position so that the axial securing device 126 engages in the recess on the blade 125 (see FIG. 8e).

[0091] FIG. 8f shows an enlarged view of the interface 124 for receiving the blade 125.

[0092] FIG. 9 shows a temporary plate fixer (“olive K-wire”) 130. The temporary plate fixator 130 has the shape of a K-wire with an olive 131.
