And Now, Robodoc!

A robot in California performs its first invasive surgery on a human patient.

Medical robots in the U.S. have been used to locate hard-to-find tumors and guide a surgeon’s scalpel, but have never actually performed surgery on people. Now that line has been crossed. At Sutter General Hospital in Sacramento, California, a 90-kg machine called Robodoc has operated on its first human patient: a 64-year-old man with a bad hip.

The robot played a key role in a total hip replacement, one of 500,000 such operations performed each year. The trick in these procedures is to create a snug hole into which the artificial hip snaps. The standard method is to jam a cutting tool into the thighbone with a handheld mallet. Robodoc, using the high-speed drill at the end of its mechanical arm, can ream a cavity that is 20 times as precise.

Robosurgery doesn’t have to stop at the hip. In Europe, where officials are less squeamish about such things, robots have assisted in operations on the brain, the prostate and the inner ear.

Rental Business

Renting, also known as hiring, is an agreement where a payment is made for the temporary use of a good, service or property owned by another. A gross lease is when the tenant pays a flat rental amount and the landlord pays for all property charges regularly incurred by the ownership. The rental business in Brazil has grown fantastically in a relatively short period of time and almost without the general public noticing. Renting is not new in the country, and it already covers more items than most consumers might think. For many years it has been common for women to rent hats, dresses, shoes and other items of clothing for weddings. As the Brazilian car industry grew, auto rental agencies appeared by the dozens. Agencies offering temporary help for offices or domestic purposes have been around for quite a long time. But you can also rent items such as furniture as well as decorative plants for home or office. Perhaps the extreme in this area is a company which rents complete new clothing for women and guarantees to exchange and renew. (Adapted from an article by Tom Barnett, “Brazil Herald’s Supplement”)
