Definitions

  • the invention relates to devices called unilateral monoaxial external fixators, which stably fix, fixate, extend, and shorten bone fragments via bone screws and wires.
  • the invention particularly relates to a unilateral monoaxial fixator system, which alleviates complications of a patient and provides remote data transfer during treatment; and which can be controlled automatically, independent from the patient, and/or by the doctor.
  • External fixator is a device which fixes bone fragments by means of bone screws or wires, in a stable way, until union is completed.
  • the first fixator advanced versions of which is being used in the present day is the fixator developed by Hoffman in 1938. This configuration is followed by Wagner's unilateral fixator. Following these developments, successful results of the llizarov external fixator, which is a circular type fixator, enabled worldwide use of these methods and devices in clinics.
  • the system of the present invention is motorized
  • Circular fixators which are different from unilateral monoaxial fixator systems, are also used with the purpose of bone extension and fixation. In the last decade, computer assisted manual and motorized circular fixators have also been disclosed. Application Nos. US 2002/0010465, EP1239784B1, EP2085037A1, EP2085038B1 , EP2417924A1 , US8333766 can be given as examples for these improvements.
  • Unilateral and monoaxial fixators are quite different systems than circular fixators; since they are less invasive then circular fixators, and they have lower risk of causing vein and nerve injuries. They are also more acceptable systems for patients. Therefore, monoaxial and unilateral bone fixator systems differentiate from circular fixators in terms of shape, function, and indication.
  • the purpose of the invention is to develop a unilateral monoaxial fixator system in order to reduce patient-related complications and enable continuous monitoring and control during treatment via remote data transfer, and thus reduce additional complications.
  • Main purpose of the invention is to reduce patient-related complications and provide remote data transfer throughout the treatment. Therefore, a novel unilateral bone fixator is developed, which can be controlled automatically by the doctor and independent from the patient.
  • Another purpose of the invention is to enable a simple and secure extension and fixation operation.
  • Another purpose of the invention is to prevent extension complications caused by the patient via its remote access feature.
  • Another purpose of the invention is to achieve savings by means of reducing the number of repeating controls where the patient has to see the doctor.
  • Another purpose of the invention is to improve the quality of bone extension by means of enabling precise extension operations via several extensions to be made during the day in short intervals.
  • Another purpose of the invention is to be able to obtain remote data about the positions of bone fragments
  • Another purpose of the invention is to provide an MRI-compatible (Magnetic Resonance Imaging) embodiment.

  • Bluetooth and/or wifi unit (optional)
  • the unilateral fixator system according to the invention is formed of below given modules, in general terms:
  • Sensor-fitted Bone Clamps are the units that hold bone fragments with the help of bone fixing screws. They are obtained by means of attaching position sensors (1.1) to the clamps of the system ( Figure 3). In this way, they can be fixed at the bone clamps via remote access by means of the axial shifting position sensors found at the bone fragments ( Figure 1 , Figure 2).
  • Joint (4) It is the joint used with the purpose of fixating bone fragments, and can be locked stably.
  • Motorized Extension-Shortening Module (3) It is the motorized extension - shortening module of the system. It is a sealed, closed system. It comprises a power-transmitting reducer (3.1) connected to the extension slot of the screwed shaft (3.10) found within the external tube (3.8); a motor (3.2) rotating the screwed shaft (3.10) via it is reducer; an electronic circuit/control unit (3.3) and sensors (3.6); and a power and data transfer socket (3.11 , 3.14) ( Figure 4, Figure 4a).
  • the system also comprises a modular control unit (9) consisting of an electronic control unit and a rechargeable battery.
  • Moduiar Control Unit (9) It is the rechargeable battery and the electronic control unit of the system. It can be connected to the motorized extension module (3) through cable and Bluetooth connections. Moreover, the module can be connected to computers and smartphones (10) through Bluetooth connection via its special software (12), and thus it can communicate with remote computers (11 ) or smartphones (10).
  • Modular Extension-Shortening Unit (6) It is an alternative embodiment of the motorized extension-shortening module (3): It is formed of two pieces:
  • L Manual Extension-Shortening Module (6a) It is formed of two interpenetrating tubes. At one end of the internal tube (6a.5), there are adaptor edge sockets (6a.5.1 and 6a.5.2) that are adapted to the joint or the metaphysis clamp. On the external tube (6a.1), there is a surface rubbed for the sliding clamp and transverse-positioned channels (6a.2) for eccentric screws (2.1) locating the clamp. The sliding clamp moves in a modular way and is fixed to the channels
  • Extension and shortening screwed shafts (6a.3) are placed in the tubes.
  • the screwed shaft (6a.3) is connected to the external tube (6a.1) via piston ring(s) and/or roller(s) (6a.4).
  • the tubes are developed such that they would only provide precise extension and shortening, without rotating.
  • Modular motor unit can be adapted to the manual extension module. The amount and time of extension and shortening, and the speed of the motor can be adjusted by the doctor in front of the patient, through the control panel connected to the data transfer socket (6.4).
  • Controlled Motorized Extension-Shortening Module (7) It is an alternative embodiment of the motorized extension-shortening module (3) of the system, and it facilitates remote access.
  • the unit consists of two closed telescopic sealed tubes. It comprises a power-transmitting reducer (7.1) connected to the extension slot of the screwed shaft (7.13) found within the external tube (7.11); a motor (7.2) rotating the screwed shaft (7.14) via it is reducer; an electronic circuit/control unit (7.3) and a rechargeable battery (7.4); a power and data transfer socket (7.6), an on off button (7.7), a wireless communication module: Bluetooth-wifi (7.8), and a position sensor (7.9) (optional) ( Figure 6, Figure 6a, Figure 6b).
  • Controlled Modular Motor Unit (8) It is obtained by addition of remote control and data transfer option to the modular motor unit (6b).
  • the system prepared for operating the fixator is operated via special software (12). With this purpose, units (8.8) with Bluetooth and/or wifi connection are present on this unit.
  • a manual on off button (8.7) found thereon can be used by the patient in emergency situations ( Figure 7, Figure 7a).
  • Smartphone (10): It is a Software-installed (Fixator operating system) (12) mobile phone.
  • the system can perform its function by means of following below given operation steps:
  • Bone is fixed with the help of bone screws by using bone screw channels at the clamps (1 , 2, 5).
  • fixation is performed by using the joint (4).
  • the operation is monitored by periodic direct or remote controls. Report is obtained about the extension amount and situation, and operating protocol can be changed, if required. In other words, the amount, speed, and time of extension or shortening can be adjusted.
