Description

TECHNICAL FIELD [0001] The present invention relates to an ORTHOPEDIC SURGICAL CLAMPING APPARATUS,

The present invention relates to a joint fixation device for orthopedic surgery, and more particularly, to a joint fixation device for orthopedic surgery, which is simple and simple in structure, And can shorten the procedure time, can adjust the position quickly and easily according to the treatment site, the purpose of the treatment, the shape of the bone, and the like, which can minimize the damage of the human bones and tissues when the bone is fixed And more particularly to a surgical joint joint fixation device.

In general, the joint disease is caused by an increase in the number of patients due to arthritis and hip osteoporotic fracture due to an increase in the elderly population in addition to the joint damage due to an accident or disease. In the early stage or mild case, If the severity of the disease is severe or daily life is impossible, surgical treatment is performed.

Surgical treatment includes articular endoscopic surgery, chondrocyte transplantation, and severe arthroscopic surgery. Artificial joint surgery involves surgically removing the damaged bone and cartilage from both sides of the joint and replacing the joint This is done by using a robot as an artificial implant.

An artificial joint operation using a robot is a surgical procedure in which an artificial knee joint implant is mounted by cutting a knee bone by rotating a cutter of a cutting device mounted at a distal end of a variable arm of a robot according to information inputted to a computer.

The artificial joint surgery as described above requires a fixing mechanism for holding both bones around the site where the implant is installed in order to stably support the bone during the operation and prevent it from swinging.

For example, as shown in FIG. 1, the fixing mechanism 1 includes a connecting rod r1 connected to a surgical robot (not shown), one side of which is connected by a clamp 11 and a pair of U- A connecting rod 13 which is connected to the other side of the fixed frame 12 by a clamp 11 and a fixing frame 12 which is connected to the fixed frame 12 by a clamp 11, There is used a joint fixation device for an orthopedic surgical operation provided with a rod-shaped fixing screw 14 inserted and installed in the bone b.

The conventional joint fixation device for orthopedic surgery described above performs the function of holding both bones around the site where the implants are installed, thereby supporting the bones during the procedure, but has the following problems.

First, in the conventional orthopedic surgical joint fixation device, since a pair of U-shaped fixed frames 12 are arranged in a manner to surround the circumference of the surgical site, the operation space is narrow and the implant is difficult to perform. There is a limit in that the operation can not be performed accurately due to the interference phenomenon during movement or operation of the robot.

Conventional orthopedic surgical joint fixation devices have a disadvantage in that a long time is required for assembly because of a large number of component parts and complicated assemblies, which increases the procedure time, thereby lowering the procedure quality and medical costs.

In addition, in the conventional orthopedic surgical joint fixation apparatus, since the fixation hole is punctured in the bone by using a drill or the like in order to install the fixation screw 14 having the rod shape on the bone, the procedure time is increased, In addition, there is a disadvantage in that the treatment period is increased because of damaging the surrounding bone, and when bone is drilled, bone regeneration is difficult and fracture easily occurs.
