AI Technical Summary

Problems solved by technology

[0003] At present, there are several problems to be solved in thoracoscopic surgery: when the operator’s wrist is in the functional position, it naturally droops, and the upper end of the incision is less utilized; after the number of operating holes is reduced, the suction device cannot be fixed in the chest cavity, resulting in smoke that cannot be discharged in time and affects the surgical process. And indirectly cause the operator to ingest more exhaust gas; the operating light is limited by the incision and cannot meet the lighting needs of the thoracic cavity, and a thoracoscope is often used as an auxiliary light source, but the strong light of a single light source has potential visual damage to the operator; There are differences in height and angle between the direct vision field of view and the thoracoscopic lens, and the learning curve for the transition from traditional surgery to minimally invasive surgery under two-dimensional conditions is long

Description

technical field [0001] The invention relates to the technical field of thoracic cavity minimally invasive surgery, in particular to a thoracic cavity minimally invasive surgery lamp block, a single-lamp device, a double-lamp device and a method for using the three. Background technique [0002] From the traditional large posterolateral incision for broken ribs, to the improved incision with pectoral muscles preserved, and then to the thoracoscopic surgery at the beginning of this century, minimally invasive thoracic cavity technology has advanced by leaps and bounds. Patients who undergo thoracoscopic surgery not only recover quickly, have fewer complications, but also shorten the length of hospital stay. Some literature reports that it can improve the 5-year survival rate of early lung cancer. With the rapid development of laparoscopic technology, the number of thoracic openings has also increased from 4 to 3, and a few skilled doctors can even perform 2-hole operations. T...
