Description

Technical Field

[0001] This utility model relates to the field of orthopedic fixation devices, and more particularly to a fixation frame for orthopedics. Background Technology

[0002] In orthopedic surgery, bone screws and plates are commonly used internal fixation methods. These connect fracture sites primarily through implantation, screw fixation, or plate fixation. The surgeon selects an appropriate length and shape of plate based on the fracture location and type, and places it at the fracture site. Subsequently, a guide is used to determine the position of the bone screw and drill holes. Finally, the bone screw is screwed into the pre-drilled holes through the holes in the plate to provide sufficient stability. The combined use of bone screws and plates provides a more robust fixation effect, particularly suitable for situations where external fixation or traction is difficult to maintain after fracture reduction, such as intra-articular fractures, multiple fractures of a single bone, or multiple fractures throughout the body. However, existing bone screw and plate structures are simple, typically involving holes in the plate with the bone screw inserted vertically into the body for fixation. This structure makes it difficult to adjust the distance and angle of the bone screw, resulting in poor fixation effectiveness.

[0003] Chinese Patent Application No. 201510895686.X discloses an orthopedic external fixator, including a support rod, a pin clamping mechanism, and bone screws. The pin clamping mechanism has multiple sets, each mainly consisting of a U-shaped clamp I, a ball-head handle, and bolts. The ball-head handle has a ball head at one end, a neck in the middle, and a tapered threaded hole at the other end for installing bone screws. The inner sides of the two side walls of the U-shaped clamp I have ball sockets, in which the ball head is placed. The ball head has an inner hole composed of two tapered holes, with the smaller opening joined together and the larger opening facing outwards. The U-shaped clamp I is elastic, with a semi-circular thin wall at its bottom, and two protrusions extending inwards along its inner arc to hold the support rod. One side of the ball socket has a threaded hole, and the other side has a smooth hole. The bolt passes through the smooth hole and the inner hole sequentially and is screwed onto the threaded hole. The bone screws in this fixator are difficult to adjust to any angle for fixation, resulting in poor fixation. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a fixation frame for orthopedics. It solves the technical problem of poor fixation effect of orthopedic fixation frames.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixation frame for orthopedics includes a base and at least three fixation mechanisms disposed on the base. The base has multiple adjustment holes. Each fixation mechanism includes a vertical rod, a first guide seat disposed at the bottom of the vertical rod, a horizontal rod that slides horizontally through the first guide seat, a second guide seat disposed on the horizontal rod, and a bone screw that passes vertically through the second guide seat. The vertical rod passes through the adjustment holes. Two first bolts are threaded onto the vertical rod and can clamp onto the base. Two second bolts are threaded onto the horizontal rod and can clamp and fix the first guide seat. The horizontal rod has a ball hole. The outer wall of the second guide seat is spherical and the second guide seat is rotatably disposed within the ball hole. Two third bolts are threaded onto the bone screw and can clamp and fix the second guide seat.

[0007] Further:

[0008] The crossbar includes a guide rod and two adjusting plates connected to the guide rod. The first guide seat passes through the guide rod, and the two adjusting plates are arranged vertically, forming an adjustment space between the two adjusting plates. The ends of the two adjusting plates are fixed by an adjustment mechanism.

[0009] The adjusting plate has a fixing hole at its end, and the adjusting mechanism includes an adjusting bolt passing through the fixing hole and an adjusting nut threaded to the adjusting bolt.

[0010] The two adjustment plates are provided with opposing arc holes, and the two arc holes and the adjustment space between the two arc holes form the ball hole.

[0011] The second guide seat has rings at the top and bottom.

[0012] The base has an I-shaped structure.

[0013] The base has 8 adjustment holes and the number of fixing mechanisms is 4.

[0014] The lower end of the bone nail has a pointed cone portion, and the bone nail has a threaded portion.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] Depending on the patient's condition, the bone screw's height can be adjusted via the vertical rod and adjustment holes, its horizontal position via the horizontal rod and the first guide seat, and its angle via the second guide seat and ball hole. After the bone screw is fixed, it can be secured with the first, second, and third bolts, providing good fixation and preventing displacement of the bone screw when the patient moves, thus better protecting the patient. Disassembly is simple: loosen the first, second, and third bolts to remove the bone screw; disassembly is quick and easy. Furthermore, once the screw angle is fixed, the second guide seat can be secured with two adjustment plates, providing good fixation and preventing displacement. Additionally, the base has eight adjustment holes, allowing for selection of different adjustment holes depending on the situation. Attached Figure Description
