Description

DESCRIPTION ulti-Purpose, Single-Plane Bone Repair Fixator
Technical Field
The present invention is especially used for repairing the forearm bone fractures and end fractures, for fixing all the long-bone fractures and the deformities occurring in the bones, for fixing the joints and for opening the distance between joint bones and keeping said bones at a certain distance.
State of Art
The repairment required in the distal end fractures of the radius bone is realized by fixing the repaired bone after the manual repairment during the surgical operation and by waiting for healing. In addition, if the apparatus is suitable, the repairment losses that will be experienced afterwards, are repaired gradually.
The problems requiring repairment anatomically in such fractures are as follows; Dorsal/Palmar Translation, Radial/Ulnar Translation, Radial/Ulnar Deviation, Flexion/Extension, Extending or Narrowing the Joint Spacing. That the functions of one apparatus comprise manual or gradual repairment features after the surgical operation can be required for a successful treatment.
Especially, there are some studies for ensuring the accurate repairment thanks to computer and/or navigation software for achieving the accurate reduction in the developing technology; however, software support is not included in the single-plane fixators yet. The software aided fixation devices have circular structure. Since, the functions are required to be performed gradually for ensuring software support in such kind of devices.
In addition, all or a majority of the above mentioned required functions cannot be achieved mechanically by means of a single device. Only one of the devices that can perform dorsal/palmar translation (DFS Dimension Distal Radius Fixator) also has the feature of performing Radial/Ulnar Translation in a limited manner. However, it cannot perform Radial/Ulnar Deviation. In addition, although it has the feature of extending that will provide joint spacing (not gradual), it does not have a feature of returning thereof to its initial status gradually (manually) during the joint spacing treatment period.
Additionally, none of said devices in the world have software support. Objects of the Invention
The object of the present invention is enable a device and software to function together, which will perform extension or repairment gradually in the treatment of a distal radius fracture or deformities or similarly, in the repairment of fractures and deformities close to joints, or in long bones, and also, will measure and calculate the required repairment by means of a computer and will inform the user how to perform said operation.
Another object of the present invention is to perform dorsal/palmar translation in the shaft of radius or one of the bones forming the joint while performing radial/ulnar translation in the other bones forming the joint.
Another object of the present invention is to perform the required opening and closing processes at the beginning of the treatment in the joint, or to ensure totally 1 mm extension or flexion in a complete one cycle with ¼ mm movement in each gradual ¼ cycle and at the same time, to perform gradual extension/flexion by means of a locking mechanism allowing extension or flexion movements.
A further object of the present invention is to perform radial/ulnar deviation during screwing applied to metacarpal bone.
Another object of the present invention is both to release flexion/expansion movements during treatment period and to fix them optionally.

Fixing Screw Detailed Description of the Invention
The proximal body (1 ) provide compression and distraction movement by means of compression/distraction rod channel (2) thereon, and compression/distraction rod (7) moving backwards and forwards therein and thus, the joint spacing is adjusted. After the movement, fixation is performed by means of compression/distraction rod fixing screw (8) in order to ensure safety. The movement amount is observed by means of scale provided at the edge of the compression/distraction rod channel (2).
The end of the proximal body (1 ) comprises compression/distraction movement nut (4), which ensures gradual extension or flexion thanks to the balls moving in the housings on the body. The proximal body (1 ) comprises wrench channel (3) at the end thereof, which will enable to hold via wrench on the body in order for said movement to be performed easily on the patient. In order to perform the movement easily when required, it is held via a wrench through said channel and movement nut wrench channel (5) provided on compression/distraction movement nut (4) is held by means of another wrench and thus, a comfortable movement is achieved. The thin channels make the manual holding easy in order to perform the rotation on the compression/distraction movement nut (4) without wrench.
The compression/distraction rod circular joint end (9) at the end of compression/distraction rod (7) provides flexion/extension movement by means of 360 degree axial movement within the compression/distraction rod circular joint housing (10). The circular joint fixing nut (6) limits the movement of compression/distraction rod circular joint end (9) within the compression/distraction rod circular joint housing (10). Said fixation is performed by means of a crew provided on ulnar/radial translation channel (19).
The distal body (17) to which the distal body ulnar/radial translation end (18) is connected moves within the ulnar/radial translation channel (19) by rotating the worm gear ulnar/radial translation movement screw (21 ) and ulnar/radial translation movement is provided. The movement amount is observed on the ulnar/radial translation scale (20). While the ulnar/radial deviation unit (23) that can move within the channel on the distal body (17) fixes the bone screws (13) to the distal body (17) by means of ulnar/radial deviation unit fixing screw (24), it also fixes the deviation angle.
The bone screws (13) passing through the holes provided on the dorsal/palmar translation unit ( 1) on the proximal body (1) are fixed by means of bone screw fixing screws (12). Dorsal/palmar translation unit ( ) on the proximal body (1) moves by rotating the worm gear dorsal/palmar translation unit movement nut (15). The direction and amount of the movement are observed through the dorsal/palmar translation unit movement scale of one of the bone screws (13), which is close to distal. After the movement is completed, the fixing that will ensure safety is achieved by means of dorsal/palmar translation unit fixing screw (14).
The present invention provides pre-op computer software and deformity analysis and treatment planning thanks to software, in which pre-op x-ray films can be uploaded in the treatment of all long bone and leg fractures and deformities, especially distal radius, the joint angles and bone mechanical/anatomical axes will be determined with the joint axes determined in accordance with Paley Principles automatically or optionally thanks to the spots or lines on the films displayed on the screen after uploading, and thus, the deformity amount will be determined; and which will show how to perform the fixation, how, where and in which way, and with what amount the osteotomy will be performed when required by a pre-op planning software, animate the determined deformity amount, osteotomy and fixation place and way on the screen, prescribes the approved treatment after animation, and assists the doctor before the surgical operation.
Similarly, computer and navigation support are achieved in the treatment thanks to the software which determines the joint angles and mechanical/anatomical axes optionally or in accordance with Paley Principles on the fixed bones through the x-ray films displayed on the screen upon uploading the x-ray films after the surgical operation, determines CORA and Origin, and also, measures the repairment by analyzing the deformity. The software output determines the movement amount of the parts that can move gradually on the device and after the movements included in the prescription are performed, repairment is achieved. The final control films of the repaired bone are uploaded to the software and deformity analysis is made again; therefore, the accuracy of the treatment is analyzed via computer and navigation software through the films obtained at the end of the treatment performed in accordance with angle and measurements determined optionally or in accordance with Paley Principles.
The Way of Applying the Invention in the Industry
The present invention is a medical device and software, which comprises a device to be used for achieving repairment in bone fractures and deformities, and/or navigation performing pre-op and post-op deformity analysis in bone fractures and deformities, measurement software determining the repairment method and result control software that will control the results.
