Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing, the present invention is entered
Row further describes.
As Figure 1-5, a kind of laparoscope lower band magnetic separator, including instrument body, described instrument body includes arc
Plectrum 1, inner core 2, lever 3 and end cap 4, arc plectrum 1 is magnetic material, and described lever 3 center has axial through hole 5, holds
Handle 3 rear portion is sleeved on end cap 4, and lever 3 rear end end face is fitted with end cap 4；Described lever 3 is fixedly connected with end cap 4, described end
4 left part centers of covering have axial blind hole 6；Described inner core 2 is tubulose, and inner core 2 front portion is placed on arc plectrum 1 rear end and is dialled with arc
