Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further illustrated.
All features disclosed in this description, or the step in disclosed all methods or process, except the speciality mutually repelled and/or step, all can combine by any way, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object, namely, unless specifically stated otherwise, an embodiment in a series of equivalence of each feature or similar characteristics.
As shown in Figure 1, surgical operation ligation clip of the present invention comprises ligation clip body 1, and described ligation clip is made up of Biodegradable polyester material, can be absorbed by the body after certain hour of having performed the operation, eliminate the trouble that second operation takes out or leaves in vivo, its physical behavior and Plastic are seemingly.
Described ligation clip body 1 is the V-shaped be made up of the first jig arm 7 and the second jig arm 8, and the opening angle of described V-shaped is 0-60 degree.That is, under naturalness, the angle of the first jig arm and the second jig arm is 60 degree, and when deployed, the first jig arm and the second jig arm can be fitted under external force, make the angle of V-shaped be 0 degree.Specifically, described first jig arm 7 is arc, and the second jig arm 8 is arc, and the radian of the first jig arm 7 medial surface is corresponding with the radian of the second jig arm medial surface, and when latch hook 3 is placed in and hooks in groove 4, the medial surface of the first jig arm 7 and the medial surface of the second jig arm 8 are fitted.Therefore, this ligation clip can be used on less blood vessel and use, because the first jig arm and the second jig arm can be fitted completely, therefore, even if less blood vessel also can be clamped firmly.
Be provided with toward interior bending latch hook 3 in the end of the first jig arm 7, be provided with in the end of the second jig arm 8 and hook groove 4, described latch hook 3 is corresponding with hook groove 4 shape size, and latch hook 3 is connected in when hooking in groove 4, the bottom of groove 4 is caught in the end of latch hook 3, be horizontally arranged with in the first jig arm 7 of latch hook 3 and hook end clamp column 6, be provided with groove end clamp column 2 in the both sides near the second jig arm 8 hooking groove 4.Wherein, described hook end clamp column 6 is cylindrical, and its width is greater than the width of the first jig arm 7, and columniform upper bottom surface pays the plane at the first place, jig arm 7 side; Described groove end clamp column 2 is made up of the cylindrical of two formed objects, the two cylindrical two sides being located at the second jig arm 8 respectively, and the distance between two columniform outside bottom surface holds the length of clamp column 6 corresponding with hook.
The described column structure hooking end clamp column as a whole formula, is fixed on latch hook corner, its be in order to the use of time, be convenient to clamp this place with ligation Clip Applier, prevent latch hook from moving, clamp this place's band moveable lock hook by Clip Applier and snap in hook groove; Described groove end clamp column is separately positioned on the two ends hooking groove, is two cylindrical pieces, in use, clamps this place with the other end of ligation Clip Applier, facilitates latch hook to snap in and hooks in groove.
In addition, several row non-slip bumps is provided with in the inner side of the first jig arm 7; The inner side of described second jig arm 8 is provided with several row No. two non-slip bumps; When described latch hook 3 is placed in and hooks in groove 4, No. two non-slip bumps and a non-slip bumps misplace.Due to the existence of non-slip bumps, for tiny blood vessel, after blood vessel is clamped by this ligation clip, due to the obstruction of projection between the first jig arm and the second jig arm, therefore cannot slide, to guarantee that thin vessels causes de-folder due to slip.
The corner of described first jig arm 7 and the second jig arm 8V font is flexible hinge 5; Described flexible hinge 5 is parabolic type flexible hinges, is made up of several reed.Its distortion is all jointly completed by one or more reed, and utilize distribution flexibility to realize concentrating distortion, the flexible hinge of this configuration has larger deformation range than the conventional flex hinge of breach type.
In addition, be provided with elastic damping material sheet in the bottom of flexible hinge 5, improve the resistance to shock of mechanism.
Flexure hinge mechanism utilizes the elastic deformation of material self, has pinpoint accuracy and linear mobile mechanism to provide.Make use of elastomeric material micro-strain and from the characteristic of replying, eliminate the idle running in transmission process and mechanical friction, the displacement resolution of superelevation can be obtained.Have that volume is little, mechanical friction, gapless and highly sensitive feature.It is flexible that the present invention adopts parabola flexible hinge to be compared to hyperbola hinge, and concentrated stress is little, and precision is high.
Operation principle of the present invention:
Described ligation clip is made up of Biodegradable polyester material, can be absorbed by the body after certain hour of having performed the operation, and eliminate the trouble that second operation takes out or leaves in vivo, its physical behavior and Plastic are seemingly.Overall in V shape structure, there is latch hook wherein one end of V shape structure two-arm, and the other end has the hook groove corresponding with latch hook, and there is flexible hinge the joint portion of V shape structure two-arm, and the angle between V shape structure two-arm can folding between 0 ° to 60 °; Therefore, when ligation clip fastens, latch hook embeds and hooks groove, makes V shape structure two-arm locking, reaches the object of ligation human body inner fluid pipeline.
For the ease of utilizing Clip Applier to use, to be also respectively equipped with close to the position of termination in V shape structure two-arm and to hook end clamp column and groove end clamp column; Under free state, the open-shaped state of ligation clip, the angle between V shape structure two-arm is about 60 °, if unclamped after force makes V shape structure two-arm close up, V shape structure two-arm has resilience force and makes it restore to close to 60 ° of angles again; If force makes ligation clip V shape structure two-arm close up, flick or make ligation clip to be in closed configuration for a long time repeatedly, due to fatigue of materials, its resilience force can weaken.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
