Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Fig. 1 ~ Figure 13, a kind of biopsy forceps of improvement, comprise the bracelet 1 connected successively, core bar 2, spring outer tube 10 and binding clip assembly 12, described bracelet 1 is clamping with the connected mode of core bar 2, described core bar 2 is socketed the slip ring 3 that can slidably reciprocate along core bar 2, described slip ring 3 drives the opening and closing of binding clip assembly 12 by the steel wire rope of boost tube 7 inside crimping, described steel wire rope outside is provided with spring outer tube 10, described spring outer tube 10 outside is provided with spring protecting sleeve pipe 11, described spring protecting sleeve pipe 11 well protects spring outer tube 10 and in use can not give a discount, spring protecting sleeve pipe 11 is crimped on core bar 2 end by fixed cover 9, snapping positioning pipe 8 in the circular groove of described core bar 2, crimp spring outer tube 10 in described positioning pipe 8, positioning pipe 8 is copper piece, can by spacing for spring outer tube 10, right locating piece 4 and left locating piece 5 is provided with in described slip ring 3, two projections 31 on slip ring 3 cross right elastic head 42 respectively and left elastic head 52 is fixed right locating piece 4 and left locating piece 5, right semi-circle groove 41 is provided with in described right locating piece 4 stage casing, the left semicircle groove 51 coordinated with right semi-circle groove 41 is provided with in described left locating piece 5 stage casing, right semi-circle groove 41 and left semicircle groove 51 are respectively equipped with the right groove 43 and left groove 53 that can coordinate, right needle tray 44 and left needle tray 54 is respectively equipped with bottom right semi-circle groove 41 and left semicircle groove 51, position-limiting tube 6 is provided with between right semi-circle groove 41 and left semicircle groove 51, described position-limiting tube 6 comprises centrosome 61, described centrosome 61 sidewall symmetry is provided with locating rod 62, thimble 63 is circumferentially with bottom position-limiting tube 6, straight trough 21 both sides of described core bar 2 are provided with some to ball 22.
Described locating rod 62 end is spherical, and locating rod 62 end can stretch into supporting ball 22.
Be provided with the through hole 64 passed for boost tube 7 in the middle part of described centrosome 61, described boost tube 7 upper end is fixed on right locating piece 4 and left locating piece 5.
