Description

Bone plate processing technology

technical field

The invention relates to the technical field of bone plate processing, in particular to a bone plate processing technology.

Background technique

Bone plate is a plate-shaped fracture internal fixation device with holes in orthopedics. It is often used in conjunction with bone screws or bone wires in clinical practice. It is divided into two types: ordinary bone plate and compression bone plate, which can be made into strips according to different purposes Shape, Y shape, L shape, T shape, etc.

In order to cut a whole bone plate into the required part shape, wire cutting is generally used as the main cutting method, but wire cutting takes a long time, and the processing time and cost are relatively high. A single processing takes about 40 to 60 minutes. In the state of wire cutting, molybdenum wire will be used as the main material for wire cutting. The molybdenum wire will break during the cutting process. At the same time, the above wire cutting method will cause the deformation of the bone plate due to the stress. , leading to the problem of bending of the bone plate after cutting, and reducing the processing efficiency of wire cutting.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated ; It can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediary, and it can be the internal communication of two components or the interaction relationship between two components. Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

In the present invention, unless otherwise clearly specified and limited, a first feature being "on" or "under" a second feature may include direct contact between the first and second features, and may also include the first and second features Not in direct contact but through another characteristic contact between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature. "Below", "beneath" and "under" the first feature to the second feature include that the first feature is directly below and obliquely below the second feature, or simply means that the first feature has a lower level than the second feature.

In the description of this embodiment, the terms "up", "down", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operations, rather than indicating Or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the invention. In addition, the terms "first" and "second" are only used to distinguish in description, and have no special meaning.

In the prior art, wire cutting is generally used as a means of cutting bone plates. Wire cutting generally heats molybdenum wire or other metal wires. When the above-mentioned processing method is used to process bone plates made of titanium alloy as the main material, the efficiency will be reduced. It is easy to break the molybdenum wire or metal wire. In addition, the bone plate will be deformed during the wire cutting process, resulting in the inability to use the above-mentioned cut and formed bone plate in the subsequent process, reducing the yield of good products.

Laser cutting uses a focusing mirror to focus the laser beam on the surface of the material to melt it, and at the same time blows away the melted material with a compressed gas coaxial with the laser beam, and makes the laser beam and the material move relative to each other along a certain trajectory, thus forming a certain Shape slit; laser cutting is the most widely used laser processing technology, it is currently widely used in automobile manufacturing, aerospace industry, sheet metal processing, ship processing and other industries.

Wherein the present invention is processed by the following steps,

S1, removing stains on the bone plate to keep the bone plate clean;

S2, loading the bone plate on the cutting platform of the laser cutting machine;

S3, start the laser cutting machine, the cutting head of the laser cutting machine moves, and cuts out the required graphics on the bone plate;

S4, taking out the bone plate after cutting;

The present invention introduces laser cutting into the medical field. After research, it is found that when laser cutting bone plates, the processing efficiency is improved. Compared with the processing efficiency of wire cutting in 40 to 60 minutes, laser cutting can cut out the bone plate in about 10 seconds. The required shape improves the cutting efficiency, increases the blanking time by 239%-359%, and shortens the blanking time. At the same time, due to the characteristics of laser cutting when cutting bone plates, no cutting force will be generated. Laser cutting There will be no deformation during the process. At the same time, because laser cutting does not use tools for cutting, the production cost is low. Because laser cutting itself has the characteristics of high energy, no cutting force will be generated when cutting bone plates.

The laser cutting machine can drive the laser cutting head to move, and drive the cutting head to cut multiple groups of radius-shaped bone plates on the bone plate under the control of the program, and the cutting parameters used are: the maximum cutting speed is 9m/min , the maximum cutting power is 3.5kw, the gas pressure during cutting is between 1.5MP and 2.5MP, the cutting gas is helium, generally any inert gas can meet the requirements of the present invention , the working distance is between 0.5 mm and 1 mm, which prevents the bone plate from being scratched, and at the same time can maintain sufficient energy density for the cutting machine to cut.

Apparently, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limiting the implementation of the present invention. Various obvious changes, readjustments, and substitutions will occur to those skilled in the art without departing from the scope of the present invention. It is not necessary and impossible to exhaustively list all the implementation manners here.
