Abstract:
Objective:To make a magnetic separator and verify its application effect in the removal of foreign bodies in laparoscopic surgery.Methods:From February 2015 to September 2019 in Chengdu Sanliu Third Hospital Affiliated to Southwest Medical University, 46 surgical patients to be searched for during the laparoscopic surgery, such as needle breakage, needle drop, and titanium clip shedding, were selected as the research object. The observation group used a self-made laparoscope with a magnetic separator, and the control group used traditional methods, such as: laparoscopy to flip the tissue and C-arm X-ray positioning. The time to find the foreign body left after surgery, the incidence of postoperative subcutaneous emphysema, and the satisfaction of the surgeon were compared between the two groups.Results:The time to find the foreign body left after surgery was (15.36±3.62)min in the observation group and (75.83±10.30)min in the control group, there was significant difference( t value was 29.384, P<0.01). The incidence of postoperative subcutaneous emphysema was 13.70% (3/22)in the observation group and 83.30%(20/24)in the control group, there was significant difference( χ2 value was 37.079, P<0.01). The satisfaction of the surgeon was 100.0%(22/22)in the observation group and 16.7%(4/24)in the control group, there was significant difference( χ2 value was 48.765, P<0.01). Conclusions:For patients with foreign bodies left after laparoscopic surgery, the use of magnetic separators can significantly shorten the time to find foreign bodies, reduce the incidence of postoperative subcutaneous emphysema, and increase the satisfaction of the surgeon.
