The surgeon inserted it into his viewer.

He underwent an operation in which surgeons inserted a metal replacement for part of the bone.

Instead, surgeons using the technique cut several small holes in an abdomen and insert a camera and specially designed surgical instruments.

The additional small incisions allow the surgeon to insert other instruments to repair damaged tissue.

Here, surgeons insert a clamp through a small incision in the chest wall to immobilize a small section of the beating heart.

The surgeons inserted skin expanders after the previous surgeries, but infections began to develop and they had to be removed.

Then the surgeons inserted a tube connected to a machine that inflated the abdomen with carbon dioxide, making the patient look pregnant.

His brain still functioned perfectly well, especially since surgeons had inserted stents in both his carotid arteries.

If there is no improvement, the surgeon then can insert a dilation balloon, which can be inflated up to 3 mm.
