Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
This utility model said tissue closure folder 10, comprise a pair arc jig arm in a certain angle, this angle can be " V " type, " U " type or other analogous shape.This arc jig arm is made up of the first jig arm 1 and the second jig arm 2, and the link elasticity of two arc jig arm connects, or two arc jig arm are one-body molded, and junction is provided with adjustment hole 3.The free end of the first jig arm 1 is provided with snap fit 11, and the free end of the second jig arm 2 is provided with snap fit gathering sill 21, and when folder closes, the free end of two arc jig arm forms interlocking structure.First jig arm 1 is provided with snap fit cramping body 12, second jig arm 2 and is provided with draw-in groove cramping body 22 near one end of snap fit gathering sill 21 near one end of snap fit 11.The clamping surface in opposite directions of the first jig arm 1 and the second jig arm 2 is provided with anti-slop serrations 4, anti-slop serrations 4 is two row slant edges 41,42, slant edge herein refers to: the bearing of trend of rib and the longitudinal axis of arc jig arm are at an angle, this angle can regulate arbitrarily, such as 0-90 ° or 90-180 °, but do not comprise 90 °, i.e. out of plumb each other, this is formed with the anti-slop serrations (bearing of trend of rib is mutually vertical with the longitudinal axis of arc jig arm) in Fig. 1 and contrasts; And the longitudinal axis both sides of two row slant edges 41,42 arcuately jig arm laterally separate, and namely two row slant edges take longitudinal axis as demarcation line, separated from one another, without occuring simultaneously; Correspondingly thereto, two row slant edges 41,42 also can form intersection point in longitudinal axis place, and this is the different arrangement of slant edge two kinds.What deserves to be explained is, the rib in this utility model anti-slop serrations, be no matter rib respect to one another in same string or two row, the oblique of rib is unfixed, can adjust arbitrarily as required, and such as, some ribs are towards having a down dip, and some ribs are oblique etc. upward.
In addition, snap fit cramping body 12 is for being located near the free end of the first jig arm 1 and the cylinder along the sidewall horizontal expansion of the first jig arm 1 or the rear wall horizontal expansion along the first jig arm 1 exceed the cylinder of rear wall transverse edge.As Fig. 1, two sides adjacent with clamping surface in the first jig arm are defined as the sidewall of the first jig arm, face opposing with clamping surface in the first jig arm is defined as rear wall.This cylinder can be two, and symmetry is located on two sidewalls of the first jig arm, or this cylinder can be one, the first jig arm rear wall horizontal expansion and exceed rear wall both lateral sides edge, this cylinder can be cylinder simultaneously.Meanwhile, draw-in groove cramping body 22 is a pair dop, and this dop is symmetrically set in the both sides, top of snap fit gathering sill 21.
As shown in Figure 2, anti-slop serrations is the slant edge that two row are parallel to each other, when the design of this slant edge makes tissue closure folder folder close blood vessel or tissue bundle, blood vessel or tissue bundle increase with the contact area of anti-slop serrations, better chucking power can be obtained, and slant edge design makes to be pressed from both sides to close to organize and not easily laterally slides along tissue closure folder, adds the security reliability of pressing from both sides and closing.
As shown in Figure 3, two row slant edges 41,42 are crisscross arranged, in wheat head shape.The anti-slop serrations of wheat head shape has good guide effect to the slip of being closed tissue bundle by folder, when the clamping surface of arc jig arm be subject to by press from both sides close tissue bundle elastic restoring force effect, to be closed by folder tissue there is slip time, the anti-slop serrations of wheat head shape can slide to the link of arc jig arm by transmitting tissue's bundle, therefore, even if being closed by folder organizes Shu Fasheng to slide, also tissue can not be caused to restraint the free end generation slip phenomenon breaking through tissue closure folder, folder is closed reliably safer.
Fig. 4 is on the basis of Fig. 3, changes the alternate directions between part slant edge.In figure, O-O line place is the demarcation line of arc jig arm slant edge of the different alternate directions of clamping surface in opposite directions from free end to link, O-O line is defined as forward wheat head shape to the slant edge of arc jig arm free end portion is staggered, and O-O line is defined as reverse wheat head shape to the slant edge alternate directions of arc jig arm link part.When the clamping surface of arc jig arm be subject to by press from both sides close tissue bundle elastic restoring force effect, to be closed by folder tissue there is slip time, the link restrainted to arc jig arm near the anti-slop serrations transmitting tissue of arc jig arm free end slides, when organizing bundle to slide into O-O line, anti-slop serrations near arc jig arm link stops the further slip of tissue bundle, make to organize bundle to be fixed, no longer slide, ensure to press from both sides the reliability of closing.
As can be seen from Fig. 5-1 and Fig. 5-2, curved of the section of slant edge 41,42 arcuately jig arm longitudinal axis.This arcwall face is comparatively mild compared to fold-line-shaped face, be there is not the larger contact point of stress or comparatively sharp keen contact surface with when pressing from both sides and close contact tissue, avoids clipping broken blood vessel or tissue bundle when chucking power is larger, improves the safety of operation.
As can be seen from Fig. 6-1 and Fig. 6-2, the section also curved of slant edge 41,42 arcuately jig arm longitudinal axis, but this arcwall face comprises the less gently sloping surface of a gradient and the larger sty of a gradient, so can increase the surface area of slant edge, make slant edge and pressed from both sides the contact area of closing tissue to become greatly, the chucking power of closed clamp to blood vessel or tissue bundle is stronger, folder closes more firmly not easily slippage, while ensure that operation safety, folder closes better effects if, reliably safer.
Use procedure: in operation, when needs are to blood vessel or when organizing Shu Jinhang folder to close, snap fit cramping body and the draw-in groove cramping body of tissue closure folder is clamped with Clip Applier, closed clamp is delivered to surgery location, applying certain power makes snap fit and snap fit gathering sill interlock, blood vessel or tissue bundle folder are closed, exits Clip Applier.The anti-slop serrations of the interlocking structure that snap fit and snap fit gathering sill are formed and arc jig arm clamping surface guarantees gripping tissue, folder is closed more firm; The design of the two arc jig arm cooperatively interacted and the adjustment hole of link junction thereof, makes the ligation expanded range of closed clamp, and folder closes more flexible, can adapt to carry out folder to the tissue of different-thickness and close.
In addition, there is the phenomenons such as slippage not, easily in existing closed clamp owing to there is chucking power, usually operation is carried out smoothly at least to need to use at least 3 pieces of closed clamps to ensure clinically, and the reliable not easily slippage of tissue closure folder of the present utility model clamping, only respectively need press from both sides in operated vessels section or tissue segments both sides and close 1 piece, decrease the use of tissue closure folder, while reducing operation risk, also reduce the operation cost of patient.
