Sammanfattning
When electrosurgery is used to cut and coagulate tissue, surgical smoke is generated and the particle content increases in the room. The purpose of this study is to describe the conditions for the development of a local extractor adapted to the activity and to develop a prototype. The activity during surgery is the most limiting factor and must be carefully considered. Operations have been observed through visits at Sahlgrenska University Hospital and several tests have been performed. These include smoke tests, measuring of capture velocities and sound level tests in the test hall at Chalmers together with particle measurements in the hybrid operating theatre at Sahlgrenska. The tests were carried out with the prototype and a new product called minisquair. The results show that both the prototype and the minisquair lowers the particle content in the room but that the capture ability is highly dependent of several factors, the main ones being flow and distance. Other measurements are needed to determine if an extractor is a possible solution to the problem. However it is still clear that if so, significantly larger capture ability is required in order to ensure a good working environment. Higher flows are therefore something that should be tested before an absolute answer can be given. A higher flow in the extractor does however create other issues that any further studies should take into account. How are the pressure conditions in the room affected and how is the air flow pattern changing?
