Description
Technical field
The present invention relates to a kind of hemostatic clamp, more particularly to a kind of tissue folder that can continuously discharge clamping, belongs to medical instrument.
Background technology
Metal clip hemostasis is one of hemostasis means of relatively broad application under scope, and skilled metal is carried out to appropriate case
Folder operation, effectively can stop blooding and prevent bleeding again, reduce adverse reaction, greatly improve the peace of hemorrhage of digestive tract therapeutic endoscopy
Entirely
Property and cure rate.The hemostatic mechanism of metal hemostatic clamp and surgery vascular ligature or suture identical, are a kind of physical mechanical
Method, using hemostatic clamp close caused by mechanical force, its surrounding tissue and bleeding vessel are ligatured in the lump, so as to close out
The blood vessel of blood, reaches hemostasis purpose with blocking blood flow, suitable for nonvariceal active hemorrhage and visible vessels stump disease
The hemostatic treatment of change.
There is the shortcomings that not easy to operate in existing hemostatic clamp, hemostatic clamp can not carry out tentative operation, once closure can not
It is again turned on, if there is operation error, partial hemostasis folder will be discarded directly.Accordingly, it is desirable to provide a kind of pressing from both sides
Repeatable folding before tight tissue, and locked hemostatic clamp can be achieved after grip tissue.Such as in Chinese invention patent
Hemostatic clamp disclosed in ZL201410222753.7 includes clamp assemblies and holder, and clamp assemblies include being sequentially connected
Clip
Body and steel wire buckle；Holder front end is equipped with fixed pin shaft, and clip body is made of two clamping limbs, two clamping limbs
Tail end connected by active pin shaft, be respectively provided with a sliding slot in the middle part of two clamping limbs, fixed pin shaft passes through sliding slot, two
A clamping limb moves back and forth the opening and closing to form clip body along sliding slot；The end of sliding slot is equipped with bending structure, when clamping limb moves
When moving so that fixed pin shaft is located in bending structure, two clamping limbs are in locked closed position.Above-mentioned hemostatic clamp passes through steel
Screw thread pulls folding of the active pin shaft to clip body to be controlled, and realizes the release of hemostatic clamp.Made in the hemostatic clamp
Component is more, and manufacture difficulty is big, and assembly reliability and stability are poor, and just pine easily has not been used
De- phenomenon.
In addition, existing hemostatic clamp is generally made using metal material, after its realization clamping hemostasis, with the surface of a wound
Healing, can voluntarily come off, and excreted along alimentary canal.Since it is needed by alimentary canal in vivo, inevitably
Human body can be caused to damage, for part population, danger caused by hemostatic clamp delay also easily occur.
And the presently used each use of hemostatic clamp can only realize the hemostasis at a position, use needed replacing newly every time
Hemostatic clamp, more wasteful time and equipment, it is therefore desirable to there is a technical ability to realize original hemostatic clamp function, and can be simply square
Just, and the apparatus of multiple hemostatic clamps can be discharged.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of tissue folder that can continuously discharge clamping.
To achieve these goals, the present invention uses following technical proposals：
A kind of tissue folder that can continuously discharge clamping, including tissue folder, spacing collar and transport system.
The tissue folder is completed by being cut by laser disposable cutting, then by process the final shapings such as heat treatment polishings, is had
Good chucking power and super-elasticity.
Preferably, chuck end holding position is organized there are two kinds of different forms of pointed tooth and knuckle-tooth according to clamping tissue difference.
Preferably, tissue folder clamping opening angle is 80-120 °.
Preferably, tissue folder rear end tails have spacing bayonet, for being connected with leading portion tooth mouth, reach what is continuously discharged with this
Effect.
Preferably, tissue folder material is NiTi tubing, has Memorability and super-elasticity.
Preferably, tissue folder chucking power scope is more than 10N.
Preferably, tissue is freely rotatable after being clipped in into working region, and rotating range is 0-360 °.
Preferably, tissue is clipped in clamp and can freely be disconnected with follow-up tissue folder after tissue, and the tissue of disconnection is pressed from both sides and will not taken off
From tissue.
Preferably, tissue folder end carries spacing kelly, can prevent spacing collar from coming off.
Preferably, tissue folder has super-elasticity by polishing treatment, and surface is smooth will not stimulate diseased region.

Embodiment
The technology contents of the present invention are done with specific embodiment below in conjunction with the accompanying drawings and are further described in detail.
As shown in Fig. 1 Fig. 2, schematic diagram when being respectively tissue folder open configuration and clamping tissue, wherein 1 is tissue collet
End, 2 be kelly, and 3 press from both sides rear end card slot for tissue.
Specifically, as shown in figure 3, being connected for two tissue folder head and the tail, it is sleeved in delivery system under the overall leadership 5, here for side
Just the connection for 2 tissue folders of description display, actual multiple tissue folder connection modes are the same, herein just with 2 tissues
Exemplified by folder.Two tissue folders join end to end, and tissue chuck end 1 is stuck in card slot 3 so that they are pushed and pulled in delivery system under the overall leadership 5
When will not fall off, with this come ensure tissue folder clamping continuity.
As Figure 4-Figure 6, when starting release clamping, tissue folder 7 and spacing collar 6 are all in delivery system for complete details of operation
In under the overall leadership 5, and perfect fitting is kept, when transport system promotes slow forward, tissue folder 7 slowly stretches out delivery system under the overall leadership 5, and
Slowly opened after opening, wherein subsidiary spacing collar 6 is also slowly released under the push of kelly 2, treat that spacing collar 6 releases delivery system
Stop push after under the overall leadership 5, spacing collar 6 at this time occurs that slight self expandable make it that the outside diameter of itself is more under the overall leadership than delivery system
Internal diameter about 1mm.
Apparatus is directed at tissue at this time, slowly withdraws transport system, tissue folder 7 will be withdrawn to delivery system under the overall leadership 5, at this time
Tissue folder 7 also will slowly grip tissue, while under the action of spacing collar 6, the head end 1 of tissue folder 7 is also by clamping, when withdrawing
To a certain extent so that spacing collar 7 is by 1 clamping of tissue chuck end, as shown in Figure 5；Then transport system is slowly released, at this time
Tissue folder 7 can slowly release delivery system under the overall leadership 5 with transport system, after tissue folder exits completely, latter one tissue folder
Head end 1 will depart from the card slot of previous tissue folder, tissue folder 7 will be completely disengaged with transport system and firmly pressed from both sides at this time
Tight tissue will not loosen, as shown in Figure 6.
Next repeatable aforesaid operations carry out the clamping work of remaining tissue, and the above then accommodates for complete a set of tissue
Flow.Tissue folder provided by the present invention is described in detail above.To those skilled in the art, not
To any obvious change that it is done on the premise of the true spirit, it will all belong to patent right of the present invention
Protection domain.
