As Figure 6-9, transfer unit includes spring hose (not shown), draught line 302 and releasing parts 20, and draught line 302 is through the inner cavity of spring hose；
Releasing parts 20 include two torque arm 204 and 205, the front end of torque arm 204/205 is respectively equipped with crook, torque arm 204/205 is connect by the crook of respective front end with intermediate plate interconnecting piece, the rear end of torque arm 204/205 is fixedly connected with the front end of draught line 302 respectively, clip 40 can be taken in and be stretched out the front end of spring hose by releasing parts 20 and draught line 302, when discharging clip 40, the crook of torque arm 204/205 deforms to be detached from intermediate plate interconnecting piece under the drive of draught line 302.
As shown in Figure 1, operating member 10 is connect with the rear end of the spring hose of transfer unit 30 and draught line 302, clip 40 is operated by driving transfer unit 30.Operating member 10 can be the common structure of this field, only enumerate a kind of implementation of operating member herein.Such as, operating member 10 may include main body 101, through inside main body 101 operating stick 102, be fixedly connected with operating stick 102 operating block 103 for controlling operating stick movement and the operation handle 104 for being fixed on body rear, operating block 103 is sheathed on outside main body 101 and can slide back and forth, the rear end of spring hose is fixedly connected on 101 front end of main body of operating member, and the rear end of draught line 302 is connect with the front end of operating stick 102 to be acted so as to drive torque arm 204/205 under the action of operating block and be further driven to intermediate plate 401/402.
As shown in figs. 10-11, in the present embodiment, a kind of implementation as clamping mechanism, clamping mechanism includes the protrusion 404c of the notch 401a/402a being equipped on intermediate plate 401/402 and the indent being equipped on stop bit part, after the income stop bit part completely of intermediate plate 401/402, the notch 401a/402a of intermediate plate firmly locks the protrusion 404c of stop bit part, and notch can be with stop bit part protrusion CONTACT WITH FRICTION.
Further, as shown in Fig. 7,10, the bottom end of intermediate plate 401/402 is respectively equipped with connecting hole, and the connecting hole that pin-fin tube 403 penetrates intermediate plate forms intermediate plate interconnecting piece, and the crook of torque arm 204/205 is connected to and (hangs on)
On the pin-fin tube 403.
Stop bit part 404 can be stretched out and be withdrawn from the distal end of spring hose, as shown in Figure 7, stop bit part 404 has inner cavity and the alar part 404a/404b that can store intermediate plate 401/402, when stop bit part 404 is in spring hose, alar part 404a/404b is shunk in the inner cavity of stop bit part 404, when the stop bit part 404 stretches out the front end of spring hose, alar part 404a/404b opens and is stuck in the endface of spring hose front end.
Further, as shown in figure 8, torque arm 204/205 is made of head end 204a/205a, middle section 204b/205b, tail end 204c/205c, torque arm head end 204a/205a is a non-closed crotch structure, and crotch and intermediate plate 401/402 pass through 403 clearance fit of pin-fin tube.The middle section 204b/205b of torque arm and the alar part 404a/404b of stop bit part cooperate, when stop bit part 404 is in spring hose, alar part, which shrinks to compress the middle section 204b/205b of torque arm, to be fixed, when stop bit part 404 is in spring hose outer end face, alar part 404a/404b expansion, torque arm 204/205 can retreat in the inner cavity of stop bit part 404.The tail end 204c/205c of torque arm is fixedly connected with draught line 302.
The operating procedure of soft tissue folder of the present invention includes: clip income spring hose, clip stretches out spring hose grasp tissue, clip folder closes tissue, clip release.First, clip is incorporated into spring hose by guiding device (not shown), draught line 302 is pushed forward, stretch out clip outside spring hose, the alar part elastic dilatation of stop bit part 404, pull back draught line 302, alar part is set to resist the end face of spring hose, intermediate plate 401/402 is resisted into tissue at this time, pull on draught line 302, torque arm 204/205 is driven to move, make 401/402 grasp tissue of intermediate plate, continue post-tensioning draught line 302, intermediate plate 401/402 is taken in stop bit part 404, pull draught line 302 again at this time, the head crotch of torque arm 204/205 deforms, clip is detached from torque arm 204/205, success discharges, the seamed edge of intermediate plate 401/402 and the cavity wall CONTACT WITH FRICTION of stop bit part 404, the head end of intermediate plate is closed Conjunction forms normal pressure.There is card slot 401a/402a structure in the clamp arm of intermediate plate 401/402, formed with stop bit part salient point 404c locked.
When stop bit part 404 is in spring hose, alar part is shunk in the inner cavity of stop bit part, relieving mechanism is prevented to move backward in the inner cavity of stop bit part 404, when stop bit part 404 stretches out the distal end of spring hose, alar part opens the endface for being stuck in spring hose end, relieving mechanism can be moved backward by the inner cavity of stop bit part 404, and intermediate plate 401/402 can be received into the inner cavity of stop bit part 404.Further, torque arm 204/205 or other connecting components can certain intermediate section (such as, the 204a/205a and 204b/205b of torque arm) at be arranged step, when stop bit part 404 is in spring hose, the alar part of stop bit part 404, which can be stuck at step, to be prevented to draw
Arm 204/205 is moved backward in the inner cavity of stop bit part 404.
Soft tissue folder of the present invention, after intermediate plate folder closes, the lateral edges of intermediate plate and the cavity wall CONTACT WITH FRICTION of stop bit part, the front end folder of intermediate plate is closed to form normal pressure closure, the indent protrusion of the notch in the clamp arm of intermediate plate and stop bit part is formed locked simultaneously, keeps intermediate plate locked for a long time, until after the completely long good closure of tissue, it falls off, stops blooding safer together with tissue.
Embodiment two
On the basis of example 1, a kind of deformation of clamping mechanism as intermediate plate and stop bit part, as shown in Figure 12 and Figure 13, stop bit part 404 has a stepped hole 414, intermediate plate 401/402 is equipped with overhead structure 411/412, after the income stop bit part 404 completely of intermediate plate 401/402, clip 40 is pulled on, the overhead structure 411/412 of intermediate plate 401/402 firmly sticks into the stepped hole 414 of stop bit part 404.
Such structure can further make intermediate plate grip tissue, and intermediate plate can be locked more muchly until falling off together with tissue again after the completely long good closure of tissue.
It should be noted that this kind of snap fit and the snap fit of embodiment one kind both can individually have been implemented, can also implement simultaneously.When implementing simultaneously, two kinds of clamping mechanisms can be set to the different location of intermediate plate and stop bit component, such as in forearm or tail arm, but be not limited to the two positions.
Furthermore, it is possible to take in clip in spring hose by guiding device, for example the pilot hole in guiding device can be set to a bellmouth, the alar part of stop bit part 404 loads in pilot hole, takes in clip 40 into spring hose by its pilot hole.
Content described in this specification embodiment is only enumerating to the way of realization of inventive concept; protection scope of the present invention should not be construed as being limited to the specific forms stated in the embodiments, protection scope of the present invention also and in those skilled in the art conceive according to the present invention it is conceivable that equivalent technologies mean.
