Cleaning device in robot ultrasonic knife operation

Abstract

The invention belongs to the technical field of medical auxiliary devices, and discloses a robot ultrasonic scalpel cleaning device which comprises a cleaning bag and a hollow long rod, one end of the hollow long rod is sleeved with the cleaning bag, the other end of the hollow long rod is connected with a handle, and a U-shaped elastic supporting rod is fixedly connected to the inner wall of the cleaning bag; two sets of inclined supporting rods hinged to first sliding rings are symmetrically hinged to the inner side wall of the U-shaped elastic supporting rod, the first sliding rings are slidably connected to the surface of the hollow long rod in a sleeving mode, and the ends, back on to the inclined supporting rods, of the first sliding rings are fixedly connected with one or more sets of connecting rods; by arranging the cleaning bag capable of being folded and unfolded, the cleaning bag can be conveniently placed in the body of a patient, and the robot ultrasonic knife can be placed in water in the cleaning bag to work for mechanical oscillation to flush out tissues and blood clots attached to a knife head area without being taken down from an operation arm of a robot system; normal output power and use of the ultrasonic knife are ensured, and the failure rate is reduced, so that the expenditure of patients or hospitals is reduced.

Description

technical field [0001] The invention relates to a cleaning device during robotic ultrasonic scalpel surgery, which belongs to the technical field of medical auxiliary devices. Background technique [0002] The full name of the ultrasonic knife is "ultrasonic cutting hemostatic knife". It is a new type of surgical equipment that has been used in clinical surgery since the late 1980s. Vaporize water molecules in tissues, break protein hydrogen bonds, disintegrate cells, cut or coagulate tissues, and close blood vessels. It has the advantages of precise cutting, controllable blood coagulation, little thermal damage to tissues, very little smoke to make the surgical field clear, and no current passing through the human body, making the ultrasonic scalpel widely used in clinical surgery. However, during the use of the ultrasonic scalpel, eschar will be produced on the blade, and at the same time, there will be tissue and blood clots in the blade area. When there is too much esc...

Problems solved by technology

Since the robotic ultrasonic scalpel must be installed on the operating arm of the robotic arm system and the surgeon under the operating table controls the cutting, only the robotic ultrasonic scalpel is removed from the operating arm during the operation, and the scorches attached to the scalpel are wiped off with wet gauze. Scab, it is impossible to put the robotic ultrasonic knife into the water to perform mechanical vibration to flush out the tissue and blood clots attached to the knife head area, resulting in a very high failure rate of the robotic ultrasonic knife, and the robotic ultrasonic knife is a disposable item and the price is very expensive. As a result, multiple robotic ultrasonic scalpels will be used in one operation, which greatly increases patient costs or hospital costs.
