MEDICAL SUPPLY SURGICAL STAPLES

 

Medical supply surgical staples are applied more quickly than sewing by hand and made of non-allergenic and non-irritating materials. These are the materials used by most surgeons and surgical consultants nowadays to put back organs together again after an operation. These medical supply surgical staples remain in place forever without the patient feeling it.

An inventor in 1862 had a bright idea of putting together pieces of papers and 100 years after, surgeons modified his invention in holding together pieces of human body parts after surgery. Slow and methodical use of needle and thread in order to sew two edges together is suturing. This suture process takes long time and there is a serious risk of bleeding and leakage. In the sixties, a Russian surgeon modified this medical supply. He made it of titanium material which is a strong metal that does not react with tissues. With the use of surgical gun, the entire procedure to inserting the surgical adhesive takes only few seconds. This microsurgical effectively stops bleeding, and prevents complication. Likewise considerably cuts down operating time. This can be easily seen on X-ray.

The skin was closed by stitching or suturing which is the traditional method. A small piece of silk or nylon is attached to a needle, pushed through both edges of the skin and then tightened in order to close the wound. Now, surgical glues can be used to close skin. It causes a little irritation or infection but it is fast and closes the wound well. They are easy to remove, too.

A medical supply surgical staple constructed from shape memory alloy (SMA) is suitable for use in laparoscopic surgery. Resistive heating via electrical current pulse is the effect of the closure of the staple. The heat sink effect of the electrical contact rails and the consideration of the presence of contact hotspots optimize the deployment protocols and minimizing thermal security damage to tissue. High-resolution thermal imaging observes the dynamic temperature distributions in SMA surgical equipment as a function of the pulse parameters. Process optimization has been facilitated and provided the data from which computational finite-element models are validated of heat transport phenomena.
