Abstract

The invention provides a treatment system for the surgical operation and a method of controlling the treatment system for the surgical operation. A treatment system (1) for surgical operation is provided with: a handpiece driving device (11) for supplying electric energy to a handpiece (10) equipped with a treatment section which can be inserted into a body cavity; a perfusion device (4) for circulating liquid in the body cavity to regulate the pressure in the body cavity; and a control circuit (43) for controlling the perfusion device (4) in association with output conditions of the handpiece driving device (11) to control the pressure in the body cavity to different levels, thereby changing the flow rate of the liquid being circulated.

Description

technical field [0001] The present invention relates to a surgical treatment system and a control method of the surgical treatment system. Background technique [0002] Conventionally, in operations under endoscopic observation in body cavities, such as arthroscopic operations in the field of orthopedics, perfusion fluid such as saline is used to inflate the joints with a perfusion pump to ensure the surgical field of view and perform disposal. As described in US Pat. No. 5,520,638 or US Pat. No. 6,007,556, the perfusion pump is controlled to supply the perfusate so that the pressure in the joint is constant while monitoring the pressure of the fluid in the joint with a pressure sensor. [0003] In addition, as a surgical treatment instrument, there is a high-frequency treatment instrument that performs treatment by passing a high-frequency current through a tissue to be treated. [0004] When high-frequency manipulation instruments are used in arthroscopic surgery, air bu...
