Description

Technical Field

[0001] The utility model relates to the technical field of medical titanium rods, in particular to a medical titanium rod bending machine with a limiting function. Background Art

[0002] Medical titanium rods are very stable in physical and chemical properties. They will not be absorbed by the human body, will not react chemically with body fluids and drugs, will not ionize, and will not react with the muscles and bones of the human body. Therefore, they are often used as connectors in joint surgery. For different positions of the human skeleton, during the operation, the medical titanium rods needed are often bent into a certain shape to match the bone shape of the patient's surgical site. Therefore, a bending machine is needed for auxiliary processing.

[0003] Publication number CN209186920U discloses a single-plane bending device for medical titanium rods, in which the bending pressing plate is fixedly connected to the load-bearing base by fastening bolts that are screwed into the screw holes A and B at corresponding positions from top to bottom. In this way, the trouble of pressing the pressing plate with hands is saved, making it convenient to free hands to manipulate the medical titanium rod clamped between the upper ends of the two bending columns. The above-mentioned device limits the titanium rod by the pressing plate, and only places the titanium rod on the outside of the load-bearing base. Moreover, the titanium rod is a metal product, and it will roll due to its own gravity, thereby causing the titanium rod to deviate and shake.

[0032] Embodiment 1: In order to solve the problem that the bending machine uses a pressing plate to limit the titanium rod, the titanium rod is only placed on the outside of the load-bearing base, and the titanium rod is a metal product, which will roll due to its own gravity, so that the titanium rod will deviate and shake.

Before processing the medical titanium rod, when the medical titanium rod needs to be placed, the fixing pin 12 is taken out so that the bottom position of the fixing pin 12 is separated from the positioning hole 11 provided at the bottom of the fixed beam 10. At this time, the position of the bending block 13 can be moved according to the size of the medical titanium rod. At this time, the bending block 13 will change its position with the bending part on one side of the dial 802, so that the medical titanium rod can be limited and fitted, and the phenomenon of displacement of the medical titanium rod can be prevented at this time.
