The specific embodiment
A kind of guiding device of tubular type binding appearance; Like Fig. 1, shown in Figure 2; The tubular type binding appearance is consistent with prior art; Comprise nail-anvil assembly (meaning not shown in the figures), nail bin groupware 11, be provided with graduation mark 14 and be fixed in the bend pipe 12 of nail bin groupware near-end that anvil pull rod 13 is arranged in the nail bin groupware 11 movably and is used for being connected with nail-anvil assembly.
Guiding device is that the body 2 of a tubular is formed with the active segment with far-end 31 and near-end 32 3; 3 one-tenth hemisphericals of active segment; Distal-most end at active segment 3 offers a circular hole 33; As shown in Figure 1, the body 2 of guiding device is coated on the periphery of nail bin groupware 11 and part bend pipe 12, can certainly only be coated on the periphery of nail bin groupware 11.
Like Fig. 4, shown in Figure 5, the active segment 3 of body 2 is by being the ectonexine structure, and outer 34 is that body 2 is own; Be the fexible film material; And have good elasticity,, evenly fixedly install 12 ribs 35 as internal layer at outer 34 inner surfacies in order to strengthen the compressive strength of skin 34; Described reinforcement can be plastic cement material, can adhesion perhaps be injected into one with fexible film.
Guiding device can move in the primary importance of nail bin groupware far-end and between the second position of nail bin groupware near-end.
Primary importance is meant guiding device position during original state on the tubular type binding appearance; After the second position is meant that nail bin groupware 11 gets into human bodies, when carrying out connecting operation between the tissue of follow-up routine, the residing position of guiding device.
When nail bin groupware 11 got into human body, guiding device is positioned at primary importance, and was as shown in Figure 1; At this moment; Circular hole 33 diameters are more smaller than the maximum outside diameter of anvil pull rod 13, make the remote card of anvil pull rod 13 in circular hole 33, provide support a little to ribs; Hard ribs 35 makes active segment 3 can in the pressure of being organized, not concave, and also can poke to be organized as the subsequent procedures action and to prepare.
And after nail bin groupware 11 gets into human bodies, need guiding device be pulled out the second position when making guiding device reach circular hole 33 to strut from the bend pipe near-end; As shown in Figure 2; At this moment, circular hole 33 is owing to shoring of nail bin groupware 11 struts, when nail bin groupware 11 stretches out from circular hole 33; Because the material of body 2, make the circular hole 33 resilient peripheries that are coated on nail bin groupware 11.
The operator moves guiding device to the bend pipe near-end for ease; The hollow taper guiding that the near-end of guiding device is arranged to disperse to periphery is along 4, and simultaneously, guiding also convexes with four circle projections 41 to increase frictional force along 4 surfaces; Thereby more be prone to the pulling guiding device, extremely shown in Figure 6 like Fig. 1.During operation, hold guiding and along 4 guiding device is spurred to operator's direction, the skin 34 of fexible film is owing to there is better elasticity at this moment, and circular hole 33 is strutted enough makes nail bin groupware 11 pass through, and stops action until graduation mark 14 places that move guiding device to bend pipe 12.And operation afterwards is a usual way in the prior art, repeats no more at this.
More than be merely this utility model most preferred embodiment, below sketch second embodiment of this utility model more respectively.
As shown in Figure 7; The guiding arrangement structure of second embodiment and most preferred embodiment is roughly the same; The body 2 that is a tubular is formed with the active segment that is attached thereto 3, and the hollow taper guiding that the near-end of guiding device is arranged to disperse to periphery is along 4, simultaneously; Guiding also convexes with four circle projections 41 to increase frictional force along 4 surfaces, the handled easily person uses.Different is, active segment 3 is conical, and circular hole 33 is opened in the distal-most end of active segment 3.Being arranged on when reducing cost so also can well be played guiding function.
In addition, need to prove that the near-end that the application mentioned is meant the end near the operator, on the contrary far-end.
This utility model compared with prior art has the following advantages.
(1) guiding device has not only helped the operator more smoothly nail bin groupware to be put into tissue, and has protected tissue because its slick and sly appearance active segment, can be owing to the excessive and damaged of the end face of Binding Instrument.
(2) manufacturing of this guiding device is simple, and is with low cost, is worth being applied widely.
This utility model still has multiple concrete embodiment, as replacing guiding along reaching all technical schemes that being equal to of identical purpose and so on replaces or equivalent transformation forms through pull bar in the prior art, all drops within the scope of this utility model requirement protection.
