Technical Field

The utility model relates to a broken bone fixer.

Background

Osteology is also known as orthopedics. Is a specialty or discipline of medicine, which is specialized in studying the anatomy, physiology and pathology of the skeletal muscle system, maintaining and developing the normal morphology and function of the system using drugs, surgery and physical methods, and treating injuries and diseases of the system. Osteology is also known as orthopedics. Is a specialty or discipline of medicine, which is specialized in studying the anatomy, physiology and pathology of the skeletal muscle system, maintaining and developing the normal morphology and function of the system using drugs, surgery and physical methods, and treating injuries and diseases of the system.

With the development and progress of science and technology, bone science has been greatly developed in diagnosis and treatment. The establishment and development of hand surgery enable the diagnosis and treatment technology of hand trauma to be rapidly popularized and improved; the extensive development of microsurgery ensures that the anastomosis and the release of the multi-toe free reconstruction hand and nerve bundles, and the anastomosis of small arteries with the diameter of 0.2mm is no longer mythical; the new operation type is adopted to treat diseases such as scoliosis, cervical spondylosis, cervical stenosis and the like, and a better bone science effect is achieved; various effective surgical methods are adopted for arthritis patients, so that the patients lying in bed for many years stand up from the new position; the treatment of malignant bone tumor has been developed from single amputation to comprehensive treatment, and the cure rate and survival rate of the operation are improved; the clinical application of the knee arthroscope not only solves the diagnosis of some difficult arthrosis, but also realizes the synchronous diagnosis and treatment; with the development of material science, some complex fractures can also be treated by internal fixation; the functions and performances of the artificial joint and the artificial vertebral body are more perfect. In summary, the development of bone science is indistinguishable from the development of basic medicine, particularly experimental medicine and material science.

In the prior art, when a patient who aims at broken bones performs an operation, a plurality of hole sites need to be arranged on the bones, the installation is troublesome, and the operation difficulty can be increased.

Based on the problems, the broken bone fixator which can be installed simply, reduces the operation difficulty and shortens the operation time is designed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a bone fracture fixer that can realize simple installation, reduce the operation degree of difficulty, shorten operation time.

In order to solve the above problem, the utility model adopts the following technical scheme:

a broken bone fixator comprises two connecting members for connecting broken bones, and a main structural rod and a secondary structural rod which are assembled on the two connecting members;

the connecting component comprises two alloy blocks which are symmetrically arranged, a bolt is assembled between the two alloy blocks and penetrates through a bone, arc-shaped bayonets are arranged on the opposite surfaces of the two alloy blocks, a contact block made of rubber is arranged in each bayonet, and the contact block is in contact with the bone; the front contact block and the rear contact block are attached and mutually limited; the contact block is provided with a through hole for penetrating the bolt; arc-shaped concave holes are formed in the opposite surfaces of the two alloy blocks, the two concave holes are combined to form a circular hole, and a plurality of first clamping grooves are formed in the hole wall of each concave hole at equal intervals from top to bottom; more than two through holes vertically penetrate through the surface of each alloy block;

the diameter of the main structural rod is larger than that of the auxiliary structural rod, and first clamping strips matched with the first clamping grooves are processed at two ends of the main structural rod;

the auxiliary structural rod is installed in the through hole, and nuts are assembled at two ends of the auxiliary structural rod.

Preferably, an arc-shaped clamping groove is formed in the inner wall surface of the bayonet, a clamping strip is formed on the outer wall surface of the contact block in an injection molding mode, and the clamping strip is fit in the clamping groove.

Preferably, both ends of the main structural rod are closed spherically; during the healing of the bone, there is a case where the muscle tissue is bonded to the main structural rod, and if both ends of the main structural rod are not closed, there is a high possibility that the muscle tissue enters into the main structural rod and the later separation is difficult.

Preferably, the surface of the nut is spherically transitional.

The installation mode of the product is as follows:

firstly, three-dimensional modeling is carried out on a broken bone position, and the broken bone is made into a model in a 3D printing mode. And (3) debugging the equipment before the operation according to the model, wherein the debugging mainly aims at adjusting the curvature of the main structural rod and the auxiliary structural rod. And the inner surface of the contact block is formed into a shape corresponding to the human skeleton by injection molding, so that the contact block is more attached to the bone.

And after the steps are completed, performing surgical installation.

The utility model has the advantages that: this product is when practical application, only need set up on the broken bone two hole sites that the installation bolt was used can, need not to set up more the hole site, shorten installation time, and every connecting elements only single bolt fixes, fixed convenience more, the structure of this product is comparatively simple, and the operation installation is comparatively convenient, shortens operation time, reduces the failure rate, is fit for using widely.
