The invention of the "iron assistant doctor"
Once Bethune assisted Professor Archibald, the famous director of thoracic surgery, in an operation. He was responsible for holding the retractor that opened the incision. After the operation, he was exhausted and determined to transform this primitive instrument. In the next few weeks, he worked hard and designed two robotic arms that can install the retractor on any operating table in a few seconds, which is more efficient than any human effort and saves an assistant. Other jobs. Bethune named it "Iron Assistant Doctor" and its advent was widely praised by the medical community.
The shoemaker's scissors inspire
At that time, the universal rib scissors commonly used in thoracic surgery were clumsy, heavy and too sharp to use. Bethune has been trying to design a device that is both light and good. equipment used. Once, when he went to repair his shoes, he saw the shoe repairman using a pair of special scissors to cut the nails out of the shoes. He was immediately inspired to buy the scissors and took them home to study. In the next few days, Bethune spent all his free time studying the shoemaker's scissors and making drawings. The result was the design of a new rib breaker. The handle of the new instrument is nine times longer than the scissor head, making full use of the lever principle, making it easier to use. The scissor tip is made of harder steel and is slightly blunt. A rubber gripper is installed on the handle to increase friction. Once the device was used, it was an immediate success and was widely used in the medical field. It was also named the "Bethune Rib Cutter."
The thorn basket turned into a medicine basket to confuse the enemy
It was convenient The medical team toured the village to treat the wounded. Bethune and his comrades designed a dressing basket - a special wooden tray was placed in a thorn basket commonly used in rural areas, and a box with several partitions was placed on the wooden tray. The box contained sterile dressings and medicines. This kind of medicine basket is easy to carry and easy to disguise. Just covering it with a piece of homespun cloth is enough to confuse the enemy. And this medicine basket is also very convenient to use. Lift the cover, take out the medicine box, and take out the medicine to change the dressing for the wounded. The wooden tray at the bottom of the basket can also hold some medicine and equipment.
An operating table that can be carried on horseback
Bethune was inspired by the dung carriers carried by local people on donkeys. After careful research and repeated consideration, Bethune designed an operating table that could be carried on horseback. A new means of transportation. The newly designed Yao Tuozi looks like a "bridge". The top of the "bridge" is a box without a lid, which can store various splints; there are three drawers on each side of the "bridge", and the drawers are equipped with several small compartments that can hold various surgical instruments and medicines; the two medicine carriers have horizontal Put up a door panel and it becomes a light and flexible operating table. It is easy to carry and can be unfolded in half an hour and folded in fifteen minutes. With this kind of bag and a dressing basket, it can hold the instruments and medicines used for one hundred operations and five hundred dressing changes. This means that an operating room, a dressing room, and a small pharmacy can all be carried on horseback.
