SCREW-HEAD BONE PLATE SYSTEM THAT CREATES GRADUAL COMPRESSION ALONG THE FRACTURE LINE.

Abstract

The invention relates to an orthopedic fixation system used to bring together and stably fix bone segments located on either side of the fracture line (11). The system includes a plate (6) to bridge the fracture line (11), a compression socket (7) created on the plate (6), and a compression screw (1) that can be anchored to the bone. The compression threads (2) on the head of the compression screw (1) are arranged to engage with the corresponding compression socket threads (8) on the compression socket (7); the conical section (3) under the head of the compression screw (1) moves on the opposing conical section (9) in the compression socket (7).By rotating the compression screw (1) through its connection socket (4), the compression threads (2) on the screw head advance in successive steps on the compression socket threads (8), creating a relative movement between the bone-anchored compression screw (1) and the plate (6) to close the fracture line (11), thus providing controlled and incremental compression. In this way, the compression function can be performed through the same compression screw (1) that remains in the implant without requiring a separate temporary pinion or compression device; the amount of compression can be determined depending on the tooth increments and can be increased with additional increments if necessary.

1 TARIFF SCREW HEAD THAT CREATES GRADUAL COMPRESSION ALONG THE FRACTURE LINE. BONE PLATE SYSTEM Technical Area The invention is relevant in the fields of orthopedic surgery and osteosynthesis; for fractures. bone segments are fixed via a bone plate and controlled compression along the fracture line 10 It is related to systems for their creation. More specifically. The invention is a plate with toothed and conical surfaces. anchored to the bone with a compression socket, in the head portion a protrusions that engage with the socket in question Progressive fracture with the combined action of compression screws 15 It relates to the bone plate system that provides compression. State of the Art In orthopedic surgery and osteosynthesis procedures, fractures 20 anatomically correct position of bone segments joining, sufficient contact pressure at the fracture line ensuring and maintaining this stability throughout the recovery process various bone plates and bone screws for this purpose It is used. Especially between two bone fragments 25 the presence of an opening or sufficient contact at the fracture line If this cannot be achieved initially, the plate will only be bone. Fixing it to the surface may not be sufficient; fracture fragments moving towards each other in a controlled manner 30 is required. In known systems for this purpose, a license plate specially shaped screw holes, elongated slots on it, 2 inclined or wedge-shaped surfaces, toothed areas, locking Various components and different screw structures are used. In known dynamic compression plate systems, generally an oval, elongated 5 compression screw located on the plate or in an eccentric position in a hole with a slanted surface the plate is being installed and as the screw is tightened, the screw head and the plate interaction between the guiding surfaces of the hole due to bone segment plate movement This is being done. Thus, the opening in the fracture line is 10 reducing or joining broken fragments together The aim is to bring it closer. However, the classical Precision of compression amount in dynamic compression plates determined in this way, in specific small steps checking, maintaining the applied compression and fracture 15 Preventing excessive compression from occurring in the line is always important. It's not easy. Also, in classic solutions, the screw head and plate... The movement between the holes is usually wedge-shaped, oval, or It is based on the principle of sliding on an inclined surface; the movement stopping at certain levels or 20 in advance for each level requiring a specified compression distance It does not provide this. Key documents from the prior art One of them, US 8,685,067 B2, “Compression Plate Apparatus” 25 This is a patent document titled "Broken Bone". a plate used for the purpose of compressing fragments It explains the system. In this system, on the license plate an elongated hole is created, and this elongated hole It has rack teeth on at least one linear edge. 30 In a pinion axle assembly anchored to bone, a separate pinion that engages with the rack teeth on the plate The gear is located there. By rotating the pinion gear, the gear... 3 its mechanism converts rotational motion into linear motion. and relative movement between a plate and a bone segment by bringing the fracture fragments closer together It provides. The system described in document US 8,685,067 B2 is controlled. This presents an important approach in terms of achieving compression. Although it is structured in a multi-part manner, it is also made of bone. a screw-mounted pinion axle, which can rotate on this pinion axle A pinion gear is a gear used to drive a gear mechanism. pinion driver tool and drill guide used when necessary, pinion placement drill guide, rack insert drill guide and Additional features such as rack inserts are included in the document. Additionally, the pinion axle after compression is applied. Removal of the assembly, in order to preserve compression 15 instead rack inserts or different bone screws Its use is foreseeable. Therefore, in this system for final fixation with the mechanism that provides compression The elements used can be separated from each other; surgical During the procedure, additional instruments, additional implant components, and more than 20 An implementation phase may be required. This structure in document US 8,685,067 B2 is particularly small. bones, volar surface of the distal radius or soft tissue 25 in terms of anatomical areas where the covering is limited This can lead to disadvantages. Separate pinion gear and drive. the use of the element, the need for an additional surgical instrument It can create. After the compression process, some removing components and replacing them with other elements, This can increase the application time and the number of steps involved. 30 In addition, gear elements in rack-pinion systems area covered on the plate, plate geometry, implant profile and adaptability to different anatomical regions 4 This can create design limitations in this respect. Therefore, the same compression function with fewer components, The element providing compression is a permanent part of the implant. by providing a more compact system that allows it to remain as it is There is a need. 5 Another important document included in the known state of the art is the US document. Titled “Bone Compression Plate” with part number 10,743,920 B2 This is a patent document. In this document, bone fragments are plated. a body 10 to bring them closer together through An extended slot structure is being created on it. Extended in the first part of the slot, a separate compression device or teeth arranged to engage with the gear section of the driver It is located there. The compression device, this gear on the plate it is placed in the section and when rotated, bone 15 by providing support against one of its segments move one bone segment towards another bone segment It causes it to happen. The document also states that the second slot of the plate in the area where the screw or fastener head can interact The surface is ramped, conical, or inclined. Fastener 20 As it gets tighter, the fastener head slides along this ramped section. And additional compression can occur along the fracture line. In document US 10,743,920 B2, the first stage of compression is described. The final assessment and additional compression phases are separated from each other. 25 In the first stage, a toothed section works on the plate. A compression tool or driver is used. This A compression tool is a tool that comes into contact with bone or can be inserted into bone. or a tip that can be inserted into a pre-drilled hole It may include. After compression occurs, this 30 The vehicle can be removed and attached to a separate fastener plate. Completing the compression by squeezing in the ramped slot or Protection can be ensured. The document also mentions different teeth. tooth groups with high frequency, compression device return Pawl or locking elements that can limit its rotation and Different compression tool geometries are described. The approach described in document US 10,743,920 B2 is compression 5 increasing the force and controlling the backward movement While beneficial in terms of maintenance, for the compression process It essentially relies on the use of a separate vehicle. Another In other words, a fastener that is ultimately placed on the bone. or by engaging the teeth on the plate with a screw, the first 10 The device providing the compression is not the same element. This situation; the use of additional compression devices during the surgical phase, the device positioning according to the bone, in some applications beforehand drilling the hole and separate fixation after compression This may require the placement of elements. 15 Additionally, the toothed slot and ramped slot arrangement on the plate, placement of the compression device and the final fastener because it needs to provide sufficient space for movement, especially low-profile or limited anatomical areas The plates designed according to this geometry and layout are 20 Additional design constraints may arise. US 8,685,067 B2 and US 10,743,920 B2 documents together. When evaluated, the aim is to create fracture compression. toothed areas on the plate, elongated slots, 25 ramped surfaces and elements anchored to bone It appears that its use is known. US 8,685,067 In the B2, compression is via a rack-pinion mechanism and separately. It is created with the help of a pinion gear. US 10,743,920 In B2, there is a separate compression 30 that engages with the plate teeth. Initial compression is achieved using the device; then by the movement of a different fastener on the ramped slot Additional compression can be performed. Both 6 The document also describes the gear / drive that provides the compression function. elements used for final implant fixation with the element There is a structural or functional distinction between them. Therefore, in the current state of the art; 5 anchored to the bone. and the head of the same compression screw that can remain in the implant circumferential protrusions or compression teeth located on this part with special compression groove teeth located on the plate by creating compression through direct contact A more compact solution is needed for this. 10 Furthermore, this mechanism is located under the compression screw head. a conical or inclined region found, plate compression on the counter-conical or angled area in its socket Supported by sliding; directing the movement, distributing the load controlled transfer, stable positions at certain stages 15 the formation and amount of compression of tooth steps useful in terms of making it predictable. will be. With such a system, separate pinion gears, temporary removal of the compression tool or after compression and additional mechanisms that need to be replaced with another element 20 without, controlled by a standard screw drive tool and Gradual fracture compression can be achieved. Problems that the invention aims to solve. Fractured bone segments are repaired using plates and screws. In orthopedic applications where it has been detected, only bone The alignment of the parts is insufficient, and at the fracture line creating an appropriate amount of compression and this compression It needs to be protected during the healing process. Especially fractures 30 The presence of an initial opening in the line, bone fragments not making full contact with each other, irregular fracture surfaces or fragments between during surgical procedure 7 If a tendency to separate arises again, standard determination screws alone provide the desired controlled compression. It may not provide this. In classic dynamic compression plates. an oval, eccentric or angled plate hole for the screw head Although its movement is utilized, the 5 obtained the amount of compression is precise in each application. identification, control in small movement steps, and Maintaining the applied compression may become difficult. Some systems in the known state of the art have 10 Rack teeth on the plate to provide compression. Gear drive elements, temporary pinion mechanisms or Separate compression devices are used. Such solutions, rotational motion to linear compression motion While it is possible to enable its conversion; the compression process is 15 a separate gear, pinion, compression tool, drive apparatus, drill guide, guiding element or after compression will be removed and replaced with another detection element This may require the use of a temporary component. This situation, the number of surgical steps increased, the surgical duration increased to 20 to prolong the process, increase the likelihood of user error, and especially in anatomical regions with limited working space This can lead to implementation difficulties. Another problem is the compression element and the final 25 The element enabling the detection is different from the other. In some known systems, the initial compression is temporary. is provided by a tool or mechanism; then this tool by removing the plate and securing it with a different screw, fastener or additional fastener. It is fixed with an element. In this approach, the compression is 30 in the final determination stage of the force obtained during its creation decrease, separation of fracture fragments, compression risk of change in amount or repetition of the process 8 It is also available. In addition, there is a temporary compression element. removal and replacement with another element, This increases the complexity of the surgical procedure. In addition, compression to be applied along the fracture line is 5 the amount is more predictable by the surgeon, repeatable and incremental adjustment There is a need for compression and screw systems. tightening torque, bone quality, plate-bone contact, screw friction between the head and the plate hole or the 10 used This may vary depending on the temporary location of the vehicle. Therefore, for example, a specific fracture opening has a specific characteristic. allowing it to be closed with multiple movement stages; each forming a stable position at the end of the stage and when needed a 15 that can provide more compression with an additional stage A solution is needed. Such a structure has both inadequate compression. It will also help reduce the risk of excessive compression. In addition, soft tissue covering such as the volar distal radius it is sensitive, the tendons run close to the plate and the implant 20 the importance of keeping the upper profile limited In applications, the compression mechanism is on the plate. It should not take up too much space. Separate pinion, gear, externally used compression device or extensive mechanical The components can complicate the plate geometry, 25 It can increase the volume of the implant and within the surgical field. This can make placement difficult. Therefore, compression... its function with as few parts as possible, preferably integrated on the screw anchored to the bone It is necessary to provide this. 30 9 Another problem the invention aims to solve is compression. During its movement, the screw head remains securely on the plate. The goal is to ensure that it progresses in a directed manner. There is only friction between the compression screw and the plate. or in systems based on simple inclined surface contact, screw 5 the head moving in an unwanted direction, irregular movement, not remaining sufficiently stable in the designated position or The compression force may be lost. Therefore, the head of the compression screw and the plate a positive and gradual engagement between the compression slot 10 providing; in addition, with the conical region under the screw head from the sliding contact of the opposing conical region in the plate housing by utilizing A mechanism is needed. In this context, the invention involves the insertion of a compression screw into the bone. anchoring it through the head of the same compression screw. gradual interaction with the plate, compression the quantity should be adjusted in predictable increments and Following compression, the relevant screw remains within the implant system for 20 minutes. It aims to offer a solution that will enable it to remain. This creates controlled compression along the fracture line, compression maintenance, temporary use in surgical procedures Reducing the number of vehicles and components, a low-profile approach. Obtaining the plate arrangement and different fracture types 25 development of an adaptive osteosynthesis system is the goal. Explaining the Figures Figure 1.
