Definitions

  • This invention relates to a distraction device and, more particularly though not exclusively, to an osteosynthetic distraction device, ie a device for lengthening of bones.
  • bones which require to be lengthened eg jawbones
  • pins that are anchored in the bone parts and extend through the skin to connect with a threaded distraction bar system that allows the gap in the broken bone to be opened up, usually at a rate of 1 mm/day for 10 to 20 days.
  • the new bone forms across the gap leading to an extension of the bone.
  • this known system leads to scarring of the face and the possibility of infection.
  • a distraction device for distracting first and second parts, said device comprising (a) first and second distraction elements which are adapted to be secured respectively to said first and second parts, said first and second distraction elements being relatively moveable in a distraction direction so as to effect distraction of said parts in use; (b) controllable means for effecting relative movement between said first and second distraction elements in said distraction direction; and (c) stop means for preventing relative movement of said first and second distraction elements in a direction opposite to said distraction direction; wherein said controllable means includes (i) at least one magnetic element which is mounted so as to be moveable under the influence of an externally applied magnetic field, and (ii) connection means having an input operably connected with said at least one magnetic 2 element and an output arranged to effect relative movement between said first and second distraction elements in said distraction direction.
  • a magnetic element which can be moved simply by application of an external magnetic field thereto enables distraction to be effected by a device having no parts which penetrate through the skin during the distraction period and without the need to bring an adjusting tool into physical contact therewith.
  • this potentially enables the device, when used for osteosynthetic distraction, to be inserted completely under the skin of a patient, thereby potentially reducing the risk of infection.
  • the device In the case of osteosynthetic distraction of the jawbone, the device can be implanted through an incision within the mouth, thereby avoiding external scarring.
  • connection means comprises a force multiplier.
  • the force multiplier comprises a screw-threaded slidable output rod and a screw-threaded rotary input element which is screw-engaged with the output rod so that rotation of the input element relative to the rod in one direction causes axial output movement of the latter to effect relative movement of said first and second distracting elements in said distraction direction; and the input element is operably connected with said at least one magnetic element so that movement of the latter under the influence of an external magnetic field causes rotation of said input element.
  • the rotary input element takes the form of a ratchet wheel having an internally screw-threaded bore therethrough for engagement with the rod, and said at least one magnetic element is reciprocatable under the influence of appropriate external magnetic fields so as to enable 3 rotation of said ratchet wheel in a stepwise manner by acting via teeth on the ratchet wheel.
  • the stop means comprises a pawl cooperating with said teeth.
  • Fig 1 is a schematic representation of an osteosynthetic distraction device according to one embodiment of the present invention (not to scale),
  • Fig 2 is a side elevation showing a detail of the device of Fig 1 ,
  • Fig 3 is a view on a larger scale showing how a tooth of the device can be moved
  • Fig. 4 is a view similar to Fig. 1 of another embodiment.
  • the osteosynthetic distraction device comprises first and second parts 10 and 12 having respective apertured flanges 10a and 12a adapted to receive fixing pins 14 and 16 which, in use, are anchored (eg by screw-engagement) in respective first and second bone parts B1 and B2 of a bone (eg a jawbone) to be distracted.
  • the first and second parts 10 and 12 are telescopically slidable relative to one another and are both hollow.
  • An internal support wall 10b provided within the first part 10 has a bore 10c therethrough which slidably and rotatably receives an elongate, externally screw-threaded rod 18.
  • the rod 18 is also slidable relative to a guide bar 20 mounted within the first part 10.
  • a ratchet wheel 22 is mounted on the support wall 10b for rotation relative thereto, but is fixed against axial movement relative to the wall 10b.
  • the ratchet wheel 22 has an internally screw-threaded axial bore therethrough for screw-engagement with the external screw-threading on 4 the rod 18.
  • rotation of the ratchet wheel 22 will result in axial movement of the rod 18.
  • One end of the rod 18 projects from the first part 10 and abuts against an end wall 12b of the second part 12.
  • the screw threading is arranged such that, if the ratchet wheel 22 is rotated in an anti-clockwise direction as viewed in Fig 2, the rod 18 is urged forcibly against the end wall 12b so that the first and second parts 10 and 12 are moved relative to one another in a distraction direction, i.e. in a direction to separate the pins 14 and 16.
  • a pawl 24 is mounted on the support wall 10b and is defined by an arm of a spring.
  • the pawl 24 cooperates with the teeth on the ratchet wheel 24 to prevent rotation of the wheel in a clockwise direction, i.e. in a direction which is opposite to that required to move the first and second parts 10 and 12 relatively in the distraction direction, but permits anti-clockwise rotation of the ratchet wheel.
  • the device further includes a slide 28 which is mounted on the support wall 10b for sliding movement vertically as viewed in the drawings.
  • the lower end of the slide 28 carries a horizontally disposed permanent magnet 30 which is disposed within the first part 10 as near as possible to that side of the device which is remote from the flanges 10a and 12a.
  • the slide 28 is disposed to one side of the ratchet wheel 22 and rod 18.
  • the permanent magnet 30 is disposed mostly below (but to one side of) the rod 18.
  • the opposite poles of the magnet 30 are on the opposite longitudinal side faces thereof.
  • the slide 28 carries a horizontal boss 32 upon which a torsion spring 34 is mounted.
  • a fixed end 34a of the spring 34 is lodged between a pair of stops 36 mounted on the slide 28, whilst a moveable end 34b of the spring 34 carries a finger 38 which projects beyond a side edge of the 5 slide 28 for cooperation with the teeth on the ratchet wheel 22 as illustrated in Fig 2.
  • the whole of the device described above is mounted in position as illustrated schematically in Fig 1 so as to lie totally under the skin S of a patient required to have bone parts B1 and B2 distracted.
  • the magnet 30 is disposed under the skin S and can be acted upon by an external magnetic field produced by an external magnet M.
  • an external magnet M When the poles of the external magnet M are orientated such as to attract the magnet 30, attraction of the magnet 30 is accompanied by downward sliding movement of the slide 28 and corresponding downward sliding movement of the finger 38.
  • Engagement of the finger 38 with one of the teeth of the ratchet wheel 22 causes the latter to be rotated through a small angle in an anti-clockwise direction to effect distraction of the bone parts B 1 and B2 by a small amount, in the manner described above.
  • Rotation of the ratchet wheel 22 in this direction is permitted by the pawl 24. If further distraction movement is required, then the external magnet M is reorientated and brought close to the skin S so as to cause a repulsive force between it and the magnet 30. This causes the slide 28 to move upwardly as viewed in the drawings. However, since the pawl 24 prevents rotation of the ratchet wheel 22 in an anti-clockwise direction, the finger 38 moves over an overlying tooth of the ratchet wheel 22 by flexing of the spring arm 34b so as to bring the finger 38 above the aforementioned tooth on the ratchet wheel 22. After this, the spring arm 34b moves the finger 38 into the tooth gap of the ratchet wheel 22.
  • the first and second parts 10 and 12 may be formed of titanium so as to be biocompatible.
  • the permanent magnet 30 may be formed of Nd-Fe-B.
  • the other parts of the device are also formed of titanium for biocompatibility.
  • the magnet M may be a permanent magnet or an electromagnet.
  • the magnet 30 in this embodiment is mounted on the first part 10 which carries spring-mounted finger 38.
  • the finger 38 engages with the teeth of a linear ratchet 40 fixed relative to the second part 12.
  • the linear ratchet 40 extends in the distraction direction and the teeth are orientated so as to allow relative movement between the first and second parts 10 and 12 in the distraction direction but to prevent relative movement thereof in the opposite direction. It wil l therefore be understood that relative of the parts 10 and 12 to effect distraction can be effected by appropriate manipulation of the magnet M adjacent to and externally of the skin S.

Abstract

La présente invention concerne un dispositif d'ostéosynthèse par distraction destiné à être inséré sous la peau d'un patient. Ce dispositif comprend des premiers et des seconds éléments de distraction (10, 12), relativement mobiles, qui sont attachés respectivement aux parties B1 et B2 de l'os soumis à distraction. Un arrangement réglable sert à effectuer un déplacement entre les éléments de distraction (10, 12) dans une direction de distraction. Cet arrangement réglable comprend au moins un aimant permanent (30) qui peut se déplacer sous l'influence d'un champ magnétique extérieur appliqué. Un mouvement de l'aimant (30) provoque un déplacement relatif entre lesdits premiers et seconds éléments (10, 12) dans ladite direction de distraction. Un mécanisme d'arrêt, tel qu'un mécanisme à encliquetage (24, 22), empêche le déplacement relatif desdits premiers et seconds éléments de distraction (10, 12) dans une direction opposée à ladite direction de distraction.
