Specific embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
As shown in Fig. 1~Figure 15, a kind of biopsy forceps and snare combined utensil, including biopsy forceps and snare, the workInspection pincers include slip ring 6, the second position-limiting tube 23, the second boost tube 24, positioning pipe 25 and binding clip component 29, second boost tube 24By being crimped on the opening and closing that its internal steel wire rope controls the binding clip 30 of the end of binding clip component 29, slip ring 6 is promoted, with the phase of slip ring 6The second position-limiting tube 23 in fixed locating piece 21 and left locating piece 22 drives the second boost tube 24, and the second boost tube 24 is inThe steel wire rope in portion promotes two binding clips 30 to open, and positioning pipe 25 is copper piece, can be spacing by spring outer tube 27, while so that secondBoost tube 24 will not be eccentric in moving process.
The snare includes slide bar 5, the first boost tube 11, the first position-limiting tube 12, conductive filament 19 and snare 31, described to leadThe end of electrical filament 19 is provided with pillar 37, and the other end of the pillar 37 connection snare 31 is provided with insulation tube 28, promotes outside conductive filament 19Slide bar 5, the first boost tube 11 being connected with slide bar 5 drives conductive filament 19 to move, and snare 31 from insulation is driven by pillar 37Stretched out outside binding clip 30 in pipe 28.
