Description

Technical Field

[0001] The utility model relates to the technical field of steel plate pre-bending, in particular to a steel plate pre-bending device for orthopedic clinical surgery. Background Art

[0002] Orthopedic clinical surgical plates are a commonly used orthopedic implant medical device, which is implanted into the human body through surgery to fix, replace or assist in the treatment of damaged bones. The materials of these plates mainly include stainless steel, cobalt alloy and titanium alloy, each with its own different material characteristics and clinical application value.

[0003] An orthopedic clinical surgical plate pre-bending device with announcement number CN 215384541 U uses a connecting rod to drive another set of sliders to move vertically through the horizontal movement of the slider. When the angle between the connecting rod and the horizontal plane is between 45° and 90°, most of the supporting force of the connecting rod is in the vertical direction. At this time, the vertical downward force is large, which is conducive to impact bending. Combined with a U-shaped positioning plate with a pre-tightening spring, it effectively solves the problems of complex structure, high failure rate and high cost of orthopedic clinical surgical plate pre-bending devices on the market.

[0004] The orthopedic clinical surgery steel plate pre-bending device can bend the steel plate by means of a dome bending head. When the device bends the steel plate, the bending angle of the steel plate cannot be adjusted. When the cylinder requires a steel plate with a different bending angle, the staff is required to change the equipment to bend the steel plate, which affects the work efficiency and therefore needs to be improved.
