Minimally invasive surgery is a kind of surgical operation,which is performed by using professional surgical instruments and equipment to inactivate,resect,repair or reconstruct the pathological changes,deformities and wounds in human body through micro-trauma or micro-approach,in order to achieve the goal of treatment,its surgical effect is equivalent to the traditional open surgery,while avoiding the morbidity of conventional surgical *** addition,it also has the advantages of less trauma,less blood loss during operation,less psychological burden and quick recovery on patients,and these minimally invasive techniques provide unique value for the examination and treatment of gastric cancer *** minimally invasive surgical techniques have developed rapidly and offer numerous options for the treatment of early gastric cancer(EGC):endoscopic mucosal resection(EMR),underwater EMR(UEMR),endoscopic submucosal dissection(ESD),endoscopic full-thickness resection(EFTR),endoscopic submu-cosal excavation(ESE),submucosal tunnel endoscopic resection,laparoscopic and endoscopic cooperative surgery(LECS);Among them,EMR,EFTR and LECS technologies have a wide range of applications and different modific-ations have been derived from their respective surgical operations,such as band-assisted EMR(BA-EMR),conven-tional EMR(CEMR),over-the-scope clip-assisted EFTR,no-touch EFTR,the inverted LECS,closed LECS,and so *** new and improved minimally invasive surgeries are more precise,specific and effective in treating different types of EGC.

This paper proposes a cyclic scheduling method for cluster tools in semiconductor manufacturing with equipment front-end module and multifunctional load locks. In this special configured cluster tools, the equipment front-end module consists of an aligner, a signal-arm robot, and two load locks integrated with coolers. Hence, the two load locks both have multifunction of filling, pumping, and cooling wafers. The multifunctional load locks may become scheduling bottleneck for a certain specified recipe. To solve this problem, the Petri net models of the above configured cluster tool is developed first. Then, based on the Petri net models and state equations, a mixed integer programming model is presented, which can efficiently determine the optimal scheduling sequence in steady state. Through experiments, the effectiveness of the cyclic scheduling method proposed in this paper is verified.
