Specific embodiment
It as shown in Figure 1, Figure 2, Figure 3 shows, is that the ESD stripper sleeve cutter that invention provides is in open state schematic diagram, place respectively
In closed state schematic diagram and rotational structure partial schematic diagram, as seen from the figure comprising:
Handle 8, it is preferred to use medical grade acrylonitrile-styrene-butadiene copolymer is made, and one end is handheld terminal, if
It is annular in order to hand-held；
Outer tube 4, it is preferred to use polytetrafluoroethylene (PTFE) is made, one end by rotatable parts (such as: bearing or card slot with
Snap ring) with connect on the outside of the other end of the handle 8；
Sliding block 7, it is preferred to use medical grade acrylonitrile-styrene-butadiene copolymer is made, and non-rotatably covers described
It outside handle 8, and can be slided along the length direction of handle 8, the sliding block 7 is equipped with electrode 6；
Inner tube 3, it is preferred to use polytetrafluoroethylene (PTFE) is made, and is placed in the outer tube 4, and one end protrudes into the handle 8, and
It is fixedly connected with the sliding block 7；
Two conductor wires in parallel and are fixed as one, are placed in said inner tube 3, and one end is located at outside inner tube 3 with one
Lasso 2 be connected, the other end protrudes into the sliding block 7, crosses the crack being arranged along its length on the handle 8 and (does not give figure
Show) and with the electrode 6 formed electrical circuit, electrode 6 can external high frequency electric generator, formed electrical circuit and realize cutting；
The lasso 2 by nitinol alloy wire etc. there is the material of shape retentivity to be made, when two conductor wires are by sliding block 7
Drive and lasso 2 made to be pushed out outer tube 4, then the lasso 2 can open and formed annular (open state as shown in Figure 1, directly
Diameter is preferably 3cm), diseased region can be entangled using the lasso 2 at this time, after lasso 2 is driven by sliding block 7 and is pulled in outer tube 4,
Lasso 2 is closed, after being of convenient length of outer tube 4 is stretched out in adjustment 2 front end of lasso, the cutting that has with the electric power that composite electrode 6 is supplied
Diseased region is smoothly removed and is cut off by function；The electric power that composite electrode 6 is supplied is matched at the metal ball shaped tip 1, can be used for cutting disease
Become and stop blooding, and is able to achieve pull-type cutting.
