Description
Bone clamp
The invention relates to a bone clamp having a first handle and a second handle which are connected to one another via a clamp joint, and having at least one bone fixation element which is assigned to the distal end of the first handle or of the second handle and is mounted on the distal end by a fixing joint, at least one clamp cheek being articulated on the bone fixation element via a jaw joint.
Imaging methods such as computed tomography (CT) with X-rays, magnetic resonance imaging (MRI), positron-electron tomography (PET) and ultrasound imaging are used in the medical field for diagnostic purposes and are also used to guide a surgeon during an operation and to support him or her during the surgical procedure by providing up-to-date information that can be made available in real time in high resolution in terms of space and time. Navigation systems are used for correct spatial orientation, which can also be used to record and evaluate the patient's movements during the operation. These navigation systems include a reference marker that must be positioned on the patient, preferably reversibly, detachably, yet in a stable, stationary connection to avoid displacement of the data. In addition to bone anchors, which are inserted invasively into the bone, bone clamps are also suitable for this purpose, whereby the specific application influences the choice between a bone anchor and bone clamps. Bone clamps are used in particular in spinal surgery, as sufficiently large and stable bones are available.
A bone clamp for attaching to a bone is known from EP 3 247 297 B1, which consists of a first handle and a second handle that are hinged together. The position of one handle can be fixed relative to the other handle by adjusting a sliding shoe slidably mounted on the one handle relative to the one handle by means of a screw rotatably and immovably mounted in the sliding shoe for contact with a sliding surface on the other handle. US 2009/0062869 Al discloses a bone clamp in which a pivoting handle is hingedly mounted on a rigid rod, wherein clamping plate carriers are mounted on the free ends of the pivoting handle and the rod, which carry clamping plates.
It is the task of the present invention to provide a bone clamp which enables improved contact with the bone surface and is gentler on the patient.
This task is solved by a bone clamp with the features of claim 1. Advantageous arrangements with useful further developments of the invention are given in the dependent claims.
The bone clamp of the type mentioned at the beginning is characterized in that the interaction of the jaw joint and the fixing joint makes it easier for the clamp cheeks to engage the surface of the bone, this being particularly promoted if the bone fixation element is formed from a first arm and a second arm, if the clamp cheeks are present in duplicate and if one of the clamp cheeks is hinged to each of the arms via the jaw joint. The clamp cheeks can be individually rotated so that, including the fixing joint and the two jaw joints, three rotational axes are available, so that the clamp cheeks function like a kinematic multi body chain and a further improved contact with the outer bone shape is possible.
In this context, it is advantageous, also for reasons of symmetry, if the fixing joint is arranged between the two arms.
It is also preferable if a groove defined by two grooved bars is formed in the free end of the arm, into which the clamp cheek is inserted, bearing supports being formed in the two grooved bars, into which a joint bolt carrying the clamp cheek is inserted in order to form the jaw joint in a simple manner.
Conveniently, the clamp cheek is formed from a bolt carrier having a passage opening and a clamp plate arranged on the bolt carrier, as the functions of the clamp cheek can therefore be separated and assigned to separate components.
In a preferred embodiment, the fixing joint in the bone fixation element is formed by a joint passage accommodating a joint axis, which is crossed by a spring passage into which a spring is inserted, which is supported on the two clamp cheeks assigned to the arms. This spring causes the two clamp cheeks in the bone fixation element to be held in a neutral position, which is advantageous if the bone clamp is initially brought to the bone through a tissue opening. This neutral position is maintained until contact with the bone is achieved, whereby the clamping force between the clamp cheeks can be at least partly equalized.
For an improved hold of the clamp cheeks on the bone surface, at least one mandrel is arranged on the clamp plate, which is preferably provided several times, whereby the mandrel is formed from two intersecting cutting edges which converge towards the free end like an arrow into a point. This design reduces the forces required to perforate the bone, as only a small amount of bone material has to be displaced. Another positive aspect is that the trauma is smaller than with a pyramidal shape of the mandrels, for example, so that the bone can heal more quickly after removal of the bone clamp.
In principle, it is possible to assign the fixation element to only one of the handles and secure the other handle to the bone using friction or a differently shaped clamping device. However, it is particularly preferred if the fixing element according to the invention is present in duplicate and if one of the fixing elements is assigned to the distal end of both the first handle and the second handle.
Furthermore, it is particularly preferred if a sleeve section is formed on the proximal region of the first handle, on the inside of which an inner thread is formed, into which a clamp element having an external thread can be screwed for contact with its free end on the proximal region of the second handle. This simple design, which does not require a sliding shoe, allows the position of the two handles to be secured in a clamping position. The clamping force achieved is thus permanently maintained. It should also be noted that the design of this securing mechanism in the proximal area can be realized independently of the measures at the distal end of the two handles, even if the advantages of securing the clamping force are particularly obvious when using the bone fixation elements according to the invention with the clamp cheeks.
It is also advantageous if a preload spring acting between the first handle and the second handle is present, which acts on the first handle and the second handle in the direction of closing the distal ends. This spring ensures a resting position of the two handles in a closed configuration, which offers advantages when inserting the sleeve clamp into the patient.
Good contact between the clamp element and the proximal area of the second handle, regardless of its position, is achieved if the free, distal end of the clamp element is free of threads and rounded.
As intended, a reference marker can be coupled to the bone clamp, for which purpose a clamp surface is conveniently formed on the outside of the sleeve section, to which the reference marker is attached. The sleeve section thus has a dual function, which in turn promotes the simple design of the bone clamp. The mounting of the reference marker can be simplified by forming a ring band at the distal end of the sleeve section.
The features and combinations of features mentioned above in the description as well as the features and combinations of features mentioned below in the figure description and/or shown in the figure alone can be used not only in the combination indicated in each case, but also in other combinations or on their own, without going beyond the scope of the invention. Thus, embodiments which are not explicitly shown or explained in the figure, but which arise from the explained embodiments and can be produced by separate combinations of features, are also to be regarded as being comprised and disclosed by the invention.
Further advantages, features and details of the invention can be seen from the claims, the following description of preferred embodiments and from the drawing. It shows:

In Figure 1, a bone clamp 1 is shown in a closed configuration as it is at the beginning of a placement of the bone clamp 1 through a tissue opening of a patient. The bone clamp 1 is formed by a first handle 2 and a second handle 3, which are connected to each other via a clamp joint 4. The handles 2 and 3 are rounded and complement each other in cross-section to form almost a circle in the area intended for insertion into the patient. A cylindrical outer surface is approximated at least in sections along the main axis of the first handle 2 and the second handle 3, with the inside of the second handle 3 projecting into the cylindrical inner opening of the first handle 2 when the distal clamping area is opened by pressing the two proximal lever ends together (Figure 18). The sleeve section of the first handle 2 projects beyond the length of the second handle 3 in the proximal direction (Figure 1). A preload spring 5 is arranged between the first handle 2 and the second handle 3, which acts on the first handle 2 and the second handle 3 in the direction of closing the distal ends. In the embodiment shown, the preload spring 5 is assigned to the proximal area of the two handles 2, 3 and is designed as a compression spring.
A sleeve section 6 is provided on the proximal region of the first handle 2, on the inside of which an inner thread 7 is formed, into which a clamp element 8 can be screwed, which has an external thread 9. The clamp element 8 can be screwed into the sleeve section 6 to rest with its free end on the proximal region of the second handle 3. The free, distal end of the clamp element 8 is formed free of threads and rounded.
This structure holds the bone clamp 1 in the closed configuration shown in Figure 1, which is particularly suitable for inserting the bone clamp 1 into patients, as the tissue is protected. Once the bone clamp 1 is approximated to the bone, the two handles 2, 3 can be adjusted against the force of the preload spring 5 (Figure 2), whereby the desired configuration can be secured by the clamp element 8 and the required clamping force can be introduced (Figure 3).
Once this has been achieved, a reference marker 10 can be coupled to the bone clamp 1, as shown in Figure 4. For this purpose, a clamp surface 11 is formed on the outside of the sleeve section 6, to which the reference marker 10 is attached. For this purpose, the sleeve section 6 can have a ring band 12 as a stop in order to also clearly define the position of the reference marker 10 relative to the bone clamp 1.
It is particularly important that a reference marker 10 fixed relative to the bone retains its position permanently, regardless of whether the bone surface has a rounded contour or a more planar contour, as can be described with regard to the spinous process 13 of the vertebrae in a spine 14 (Figures 13 to 16). For this purpose, the bone clamp 1 has at least one bone fixation element 15 associated with the distal end of the first handle 2 or the second handle 3. In the embodiment shown, the bone fixation element 15 is provided in duplicate, with one of the bone fixation elements 15 being associated with the distal end of both the first handle 2 and the second handle 3. The distal end of the handles 2, 3 is slightly larger in outer diameter than the proximally adjacent course (Figure 1).
The bone fixation element 15 is mounted on the distal end by a fixing joint 16 (Figure 5), at least one clamp cheek 17 being articulated on the bone fixation element 15 via a jaw joint 18. In the embodiment shown, the bone fixation element 15 is in turn formed from a first arm 19 and a second arm 20, so that the clamp cheeks 17 are present in duplicate and one of the clamp cheeks 17 is articulated on each of the arms 19, 20 via the jaw joint 18 (Figure 7).
Figure 7 shows in detail the structure of one of the bone fixation elements 15. The fixing joint 16 is arranged between the two arms 19, 20 and in the free end of each arm 19, 20 there is a groove 22 defined by two grooved bars 21, into which the clamp cheeks 17 are inserted. Figure 7 also shows that bearing supports 23 are formed in the two grooved bars 21, into which a joint bolt 24 carrying the clamp cheeks 17 is inserted. At the distal end of the first handle 2 and the second handle 3, a surface section is arranged such that a contact surface 34 is provided for the bone fixation element 15, namely on the grooved bars 21, with the clamp plate 27 being wider than the groove 22. The contact surface can be angled (Figure 19) to allow greater deflection.
The clamp cheeks 17 themselves are formed from a bolt carrier 26 having a passage opening 25 and a clamp plate 27 arranged on the bolt carrier 26.
In the bone fixation element 15, the fixing joint 16 is formed by a joint passage 29 accommodating a joint axis 28, which is crossed by a spring passage 30 into which a spring 31 is inserted, which is supported on the two clamp cheeks 17 associated with the arms 19, 20, namely the bolt carriers 26. This spring 31 causes the clamp cheeks 17 to be aligned in a rest position, as shown in Figure 9, from which the clamp cheeks 17 can be deflected (Figures 8 and 10) in order to be able to conform to the contour of the bone surface. If the contact of the clamp cheeks 17 with the bone surface is lost again, the clamp cheeks 17 return to the rest position as a result of the action of the spring 31.
Furthermore, at least one mandrel 32 is arranged on the clamp plate 27, which is present several times in the embodiment shown. The mandrel 32 itself is formed from two intersecting cutting edges 33, which converge towards the free end in the shape of an arrow to form a point. This design means that only low forces are required to perforate the bone, as only a small amount of bone material has to be displaced, which also promotes healing as only small areas are affected. In addition, the shape prevents unintentional "pinching off" of the bony structure (spinous process). The vertical extent of the arrow-shaped cutting edges 33 is relatively large. This promotes stabilization in relation to the bone. The number of cutting edges 33 is not necessarily limited to two; for example, there could also be three blades at an angle of 1200.
In the following, the use of the bone clamp 1 according to the invention will now be briefly described. An access to the bone to which the bone clamp 1 is to be attached is placed in the patient. Starting from the configuration shown in Figure 1, the bone clamp 1 is inserted in the direction of the bone, protecting the patient's tissue from the aggressive mandrels 32 of the bone fixation element 15. The configuration shown in Figure 1 is determined by the preload spring 5 and the spring 31.
Once the bone clamp 1 is approximated to the bone, the proximal ends of the handles 2, 3 can be pivoted towards each other to open the distal ends. The pivoting can be done manually, or also by screwing the clamp element 8 into the sleeve section 6 until the desired opening angle is reached. In this configuration, the bone fixation elements 15 can be aligned with the bone contour by pivoting the clamp cheeks 17 via the jaw joints 18 and aligning the bone fixation element 15 via the fixing joint 16. Once this is done, the clamping force is increased by further rotating the clamp element 8 in the sleeve section 6.
The reference marker 10 can then be attached to the outer clamp surface 11 of the sleeve section 6 with a clamping ring.
After the end of use, the reference marker 10 and the bone clamp 1 are removed in the reverse order, whereby rapid wound healing is promoted after removal of the mandrels 32 from the bone due to the low trauma.
