Description
Technical field
The present invention relates to intracavitary linear cutting anastomat fields, and in particular to a kind of intracavitary cutting kiss for preventing tissue from sliding
Clutch component is suitable for alimentary canal surgery stitching operation.
Background technique
Intracavitary Endo-GIA component is a kind of alimentary canal needle holder being applied to surgery Minimally instrument.Intracavitary Endo-GIA includes protection
Casing, support nail-plate, cutter, nail bin and multiple staples, one end of protection tube is connected to nail-plate and nail bin, support nail-plate and
The rotation connection of both nail bins, staple and cutter are installed in nail bin.Intracavitary Endo-GIA needs pair during the work time
The physiological tissue of suture is effectively gripped under reasonable squeeze, to guarantee that staple can effectively penetrate tissue simultaneously in product
Obvolvent, and tissue is cut by cutter.But in clamping organizational process, tissue is easy to slide to the distal end of instrument；
In cutting organizational process, cutter need to move to distal end and cut tissue to be cut since the frictional force of clamping face is inadequate
When cutter may push tissue the distal end of instrument to, cannot be aligned after causing staple to go out to follow closely and support nail to corresponding on nail-plate
Slot, and then cannot effectively suture.The problem can all prevent tissue from by strong clamping and not in above-mentioned two situations
Effectively it can be sutured and be cut, influence surgical effect.
Summary of the invention
The present invention provides a kind of intracavitary Endo-GIA component for preventing tissue from sliding, existing intracavitary its object is to solve
Endo-GIA component bad problem of grasping force in tissue clamping, suture, cutting process.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: it is a kind of prevent tissue slide intracavitary cutting coincide
Device assembly, including nail-plate, nail bin and multiple staples are supported, the root of the root and nail bin to nail-plate is rotatablely connected, described
Staple is mounted in nail bin, and nail bin is equipped with the clamping face for clamping tissue；Define one end towards the nail bin of attending physician
For the proximal end of nail bin, one end of the nail bin far from attending physician is the distal end of nail bin, and the clamping face is equipped with tool slot, feed
The trend of slot is the distal end from the proximal end of nail bin to nail bin, and the tool slot is equipped with the multiple nail hole out for going out for staple and following closely,
Move towards anti-skidding as longitudinally, on the clamping face being horizontally arranged on close each position of nail hole out using the tool slot
Convex ribs；The both ends of the nail hole out are equipped with the nail pin slot for the nail pin by the staple, the anti-skidding convex ribs and nail pin slot
Adjacent, anti-skidding convex ribs are equipped with guide surface, which connects with the notch of nail pin slot.
Related content in above-mentioned technical proposal is explained as follows:
1, in above scheme, preferable scheme is that the tool slot is located on the middle position of clamping face, and the two sides of tool slot are each
There are three step, the nail hole out is provided on each step；According to the order apart from tool slot from the near to the distant, the institute of every side
The height for stating three steps gradually decreases, and the highest step of height is high-order, and the minimum step of height is low order, highly between institute
Stating the step between high-order and low order is scala media, and the anti-skidding convex ribs are arranged in the scala media and low order.Wherein, " tool slot
Two sides respectively there are three step " refer to every side of tool slot all there are three step, there are six steps in total for two sides.
2, in above scheme, preferable scheme be the nail pin slot slot bottom staple go out nail side extend upwardly to it is anti-skidding
At the top surface of convex ribs.Certainly, when with Mold Making, the guide surface of anti-skidding convex ribs can also be with the setting face of the notch of nail pin slot
Integrally extend.
3, in above scheme, preferable scheme is length direction the walking perpendicular to the tool slot of the anti-skidding convex ribs
To the length direction of the nail hole out is parallel to the trend of the tool slot.
Compared with prior art, beneficial effects of the present invention:
(1) present invention increases clamping face by the surface of nail bin being the anti-skidding convex ribs of increase lateral projection on clamping face
Skin-friction force, tissue sliding when effectivelying prevent clamping and cutting tissue ensure that staple can be more accurate when going out and following closely
Alignment is supported on nail-plate and supports nail slot；
(2) under the assembly of instrument and unused state, in nail bin staple nail pin towards go out nail hole outside and with nail hole out
It is mouthful concordant or be slightly exposed to out outside nail hole, enter in organizational process in intracavitary Endo-GIA component, it is concordant with nail hole mouth out or
The staple nail pin being slightly exposed to out outside nail hole is easy to scratch tissue, and respectively there are three steps for the two sides of tool slot of the invention, guarantee
Staple nail pin in high-order and scala media is located in nail hole to be come without exposing outside, and prevents the instrument from entering staple in organizational process
Nail pin scratches tissue；The setting of step also further enhances instrument when clamping and cutting tissue to the grasping force of tissue；
(3) anti-skidding convex ribs of the invention are adjacent with nail pin slot, and the guide surface on anti-skidding convex ribs connects with the notch of nail pin slot,
Purpose is to increase the guidance for staple nail pin when following closely, increases the good molding of guidance staple, be sewn tissue with guarantee
Effectively suture and cutting separation.
It slides, ensure that in short, the present invention can effectively prevent group to be woven in component when clamping and cutting tissue
It is sewn the effective suture and cutting separation of tissue.
