Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a sternum plate device.
Background
In some thoracic procedures, the surgeon needs to cut the sternum lengthwise in the middle and at the end of the procedure, fix the two halves of the sternum together to allow the bone to heal. Previously, stainless steel wires were used to secure the sternum halves together, and the stainless steel wires were wrapped around the sternum to secure the sternum halves. These wires are often inexpensive, easy to use and quick to install, and although they are effective for many patients, they are thin and have poor flexibility, and they are highly stressed on bones, which can easily cause complications such as bone dehiscence and infection, especially in patients with severe osteoporosis. With the development and application of the structure for fixing two halves of the sternum after such surgery, chinese patent document CN201320673498.9 discloses a sternum bandage, which is used to fix two halves of the sternum by a bandage or a combination of the bandage and the sternum plate, but after the sternum plate and the sternum are fixed by the bandage, the bandage is freely wound and bound on the sternum plate, and the sternum plate is easily expanded during breathing after the fixation, which is prone to relative sliding, and therefore, the healing of the patient is not good after the surgery. In order to solve this problem, chinese patent document CN202010770615.8 discloses a sternal closure cerclage, a plate implant and an instrument, it is common that body portion 30 may also include a plurality of tabs 36 that cooperate to define a channel 38 through which band 14 is slidably received, by providing a plurality of tabs 36 to form a defined channel 38, therefore, and further, by setting the tensioning device 18, strap 14 is then installed and used such that strap 14 is secured to bracket 16, thereby, by setting the restraint channel 38 to slidably restrain strap 14, however, the provision of the plurality of tabs 36, and particularly the plurality of tabs 36, increases the thickness of the integral frame 16, and since the thickness of the skin and muscle in the sternum area is small, the thickness of the sternum area, and therefore, in the case of a thicker bone plate, greater tension is imparted to the muscle when the skin and muscle are sutured, and, therefore, improving the efficiency of the surgery without increasing the thickness of the bone plate while ensuring the strength of the bone plate is a problem that needs to be solved.
