In the first state shown in Fig. 1, this is protruding relative to one another to elastic component 11, thus forms the shape from the middle position the length direction of this elastic component 11 to two ends flaring.In this middle position, this is minimum to elastic component 11 distance each other, and this minimum range is substantially equal to or is slightly less than the diameter of seal wire 1, thus seal wire 1 as illustrated in fig. 1 this minimum distance be sandwiched in this to elastic component 11 between.
In the second state shown in Fig. 2, this to elastic component 11 towards mutual away from Direction distortion.Thus, this to elastic component 11 at the mutual spacing of middle position from being greater than their distances at two ends place.Thus, seal wire 1 and the conduit 2 be connected on this seal wire can be discharged from this seal wire erecting device 10.
This is linked together by connector 12 to elastic component 11.As shown in Figure 1, connector 12 is arranged on this one end place to elastic component 11.Certainly, also on the two ends of elastic component 11, all connector can be set.This connector 12 can be rigidity.
The operational approach of seal wire erecting device 10 is as follows: first, and seal wire 1 is inserted seal wire erecting device 10 from one end of seal wire erecting device 10, until this is to the minimum middle position of the spacing of elastic component 11.Or, the seal wire erecting device 10 being mounted with seal wire 1 in advance can be provided.Then, conduit 2 is inserted from the other end.In the process, conduit 2 is subject to this guiding to the diverging shape between elastic component 11, thus can aim at seal wire 1 exactly.Further, be set to less than the diameter of conduit 2 by this to the minimum range between elastic component 11, therefore, in the process inserting conduit 2, conduit produces radially outer power to elastic component 11, forces this to elastic component 11 towards Direction distortion away from each other.Thus, insert seal wire erecting device 10 along with by conduit 2, this is deformed to the second state shown in Fig. 2 to elastic component 11 from the first state shown in Fig. 1, allows the conduit 2 connected and seal wire 1 to take out from seal wire erecting device 10 thus.
< second embodiment >
Fig. 3 and 4 schematically shows the second embodiment of the seal wire erecting device for conduit of the present utility model.As shown in Figures 3 and 4, the seal wire erecting device 20 of the second embodiment comprises the cylindrical shell 21 of a circular cross-section.This cylindrical shell 21 can be made up of elastomeric material, and the same with the seal wire erecting device 10 of the first embodiment, can move between a first state and a second state.
Wherein, as shown in Figure 3, when this cylindrical shell 21 is in the first state, this cylindrical shell 21 is from centre position along its length to the shape of two ends flaring.Further, the minimum diameter of position is equal to or slightly less than the diameter of seal wire 1 therebetween, thus can clamp seal wire 1 in this middle position.
As shown in Figure 4, when this cylindrical shell 21 is in the second state, this cylindrical shell 21 one-tenth is from centre position to the shape of two ends convergent.Thus, discharge the clamping to seal wire 1, thus seal wire 1 and the conduit 2 being connected to this seal wire 1 can be taken off from seal wire erecting device 20.
Be similar to above about first embodiment the operation described method, when conduit 2 is inserted seal wire erecting device 20, diameter due to conduit 2 is greater than the minimum diameter of seal wire erecting device 20 position therebetween, and therefore conduit forces cylindrical shell 21 to be deformed to the second state from the first state.
The same with the first embodiment, can insert in seal wire erecting device 20 by seal wire 1 at operating room scene, seal wire 1 also can be contained in seal wire erecting device 20 in advance.
< the 3rd embodiment >
Fig. 5 schematically shows the 3rd embodiment of the seal wire erecting device for conduit of the present utility model.Wherein, the seal wire erecting device 30 of the 3rd embodiment has body 31, the form of this body cylindrical shell in the form of a truncated cone.Axis along this body 31 is provided with axial groove 32, and this axial groove 32 extends to its outer surface from the inner surface of body 31.Body 31 can be made up of elastomeric material.Like this, due to the setting of axial groove 32, body 31 can elastic deformation, thus conversion between the less contraction state (the first state) of diameter and the larger expansion state (the second state) of diameter.
As shown in Figure 5, at smaller diameter end 311 place of body 31, seal wire 1 is inserted in seal wire erecting device 30.When body 31 is in contraction state, the diameter of this smaller diameter end 311 can be equal to or slightly less than the diameter of seal wire 1.Further, the width of axial groove 32 is also less than the diameter of seal wire 1.Thus, seal wire 1 can be clamped in seal wire erecting device 30.
When being connected with seal wire 1 by conduit 2, insert conduit 2 from the larger diameter end 312 of body 31.In the process, body 31 provides the guiding function to conduit 2 from larger diameter end 312 to the convergent configuration of smaller diameter end 311, thus contributes to conduit 2 to aim at seal wire exactly.Further, body 31 diameter is at least partially less than the diameter of conduit 2, thus along with the insertion of conduit 2, body 31, from contraction state elastic deformation to expansion state, makes the width of axial groove 32 become large.
By the setting to the diameter of body 31 and the width of axial groove 32, make when body 31 is deformed to its expansion state, the width of axial groove 32 is increased to the degree of the diameter being greater than seal wire 1, thus through axial groove 32, seal wire 1 can be taken out body 31.
The modified example > of < the 3rd embodiment
Fig. 6 shows the modified example made on the basis of the 3rd embodiment shown in Fig. 5.Wherein, elastic clip 33 is set at smaller diameter end 311 place of body 31.This elastic clip comprises two cross one another legs 331 and 332.This elastic clip 33 applies inside bias force by leg 331 and 332 pairs of smaller diameter end 311, thus seal wire 1 can be clamped in smaller diameter end 311 place.
When inserting conduit 2, the bias force that conduit 2 makes body 31 overcome elastic clip 33 to apply, leaves leg 331 and 332 points, and the width of axial groove 32 is increased.
In this modified example, provide elasticity owing to being provided with elastic clip 33 for body 31, therefore body 31 can be made up of non-elastic material.
It is contemplated that, in the first and second embodiments of the present utility model, also can be provided with the biasing mechanism as elastic clip 33 similarly.This biasing mechanism can be arbitrary structures well known in the prior art, under the seal wire erecting device 10,20 in the first and second embodiments is biased in its first state.In this case, the elastic component 11 in the first embodiment can substitute by non-resilient, and the cylindrical shell 21 in the second embodiment also can be made up of non-elastic material.
The maintaining body > of < seal wire erecting device
In above-described first ~ three embodiment and modified example, before conduit 2 not being connected to seal wire 1, seal wire erecting device must keep the state clamping seal wire 1.But, the state of seal wire erecting device likely unexpectedly from the state transfer of its clamping seal wire 1 to release seal wire 1.Such as, in transportation, seal wire erecting device is likely subject to the effect of external force, or arrange in the situation of the modified example of biasing mechanism above-mentioned, biasing mechanism may surprisingly lose efficacy.
Therefore, in the preferred case, in seal wire erecting device, retaining member can be set extraly.Below, the embodiment of this retaining member will be described for the 3rd embodiment.
As shown in Figure 7, an example of retaining member is the elastic webbing 41 arranged around body 31.This elastic webbing 41 can be arranged when such as transporting seal wire erecting device 30 grade, thus, the state that this elastic webbing 41 makes body 31 remain retracted.
When surgeon before the surgery in use seal wire erecting device 30 time, can easily elastic webbing 41 be taken off from seal wire erecting device 30, thus when insertion conduit 2 time, body 31 can become expansion state from contraction state.
Elastic webbing 41 also can be arranged on the cylindrical shell 21 in flexure strip 11 in a first embodiment and the second embodiment similarly.
Another example of retaining member has been shown in Fig. 8.At the lower end of two legs 331 and 332 of elastic clip 33, retaining pin 42 is set.This retaining pin 42 is made up of rigid material, thus two legs 331 and 332 that can limit elastic clip 33 in the process of such as transporting are separated from each other.
This retaining pin 42 is provided with the weakenings 421 that size reduces.When using seal wire erecting device before the surgery, retaining pin 42 just can be made to disconnect at this weakenings 421 place by applying a less power, thus removing the restriction to motion mutually between leg 331 and 332.
