Description
Technical field
What the present invention relates to is that medical instruments field is used in operation, specifically, relates to a kind of linear type Endo-GIA with double safety mechanism, and it can load stitching and cutting that the linear type cutting element undergos surgery simultaneously.
Background technology
Linear anastomat is claimed the digestive tract closer again, is a kind of apparatus that can the seams nail of a plurality of arrangements that intermesh is in line organizationally and hammer into, and also is one of the apparatus of instead of manual straight line stitching that is widely used.Be mainly used in and sew up the stump of closing stomach, duodenum, small intestinal, colon, for the holostrome eversion type is sewed up.
There is a shortcoming in traditional linear anastomat at present, that is: doctor's operation skill has nothing in common with each other, and the art formula is inconsistent; When positioning needle is not inserted in the liner locating hole fully, after the folded tissue that closes receives the extruding of anastomat jaw, can produce excessive at the opening of jaw; Organize and be not completely enclosed within positioning needle and the jaw; Cause unnecessary organizing not sewed up or cutting, thereby increased the artificial risk of sewing up again, make troubles for doctor and patient.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; A kind of linear type Endo-GIA with double safety mechanism is provided; Be a kind of linear type Endo-GIA with closed insurance institution and percussion insurance institution, its effect is to make the hook on the safety block stop the associated components motion through torsion spring torsion and reed elastic force.Need to load the linear type cutting element and open percussion insurance institution, after the promotion push button open closed insurance institution, can operate close handles and firing handle parts and drive the linear type cutting element.
The linear type Endo-GIA that the present invention has double safety mechanism is to take following technical scheme to realize:
Linear type Endo-GIA with double safety mechanism comprises closed insurance institution, percussion insurance institution, left plate, dividing plate, drive plate, liner, right plate, shell, close handles, firing handle parts, left socle plate and right support plate; Said linear type Endo-GIA can load or remove the linear type cutting element;
Said closed insurance institution comprises push button, thimble seat, pin one, closed insurance parts, torsion spring and thimble; Closed insurance parts are connected through pin one with torsion spring, make the hook on the closed insurance parts stop partition movement through torsion spring torsion; Need to promote push button open closed insurance institution, thimble seat continues to promote thimble, and thimble promotes the positioning needle in the linear type cutting element, after positioning needle is inserted the locating hole of liner, can operate close handles and make the apparatus jaw closed;
Said percussion insurance institution comprises reed, pin two and percussion safety block; The percussion safety block is connected through pin two with reed, makes the hook on the percussion safety block stop the drive plate motion through reed elastic force; After needing loading linear type cutting element to open percussion insurance institution, can operate the firing handle parts and make drive plate drive the linear type cutting element;
When the closed insurance institution of said linear type Endo-GIA all is in open mode with percussion insurance institution, just can the normal running anastomat.
The percussion insurance institution of said linear type Endo-GIA has the linear type of preventing cutting element secondary and reuses.
Said closed insurance institution places the near-end of linear type Endo-GIA.
Said percussion insurance institution places the far-end of linear type Endo-GIA.
It is reasonable in design that the present invention has the linear type Endo-GIA of double safety mechanism; Compact conformation; Be a kind of linear type Endo-GIA with closed insurance institution and percussion insurance institution, its effect is to make the hook on the safety block stop the associated components motion through torsion spring torsion and reed elastic force.Need to load the linear type cutting element and open percussion insurance institution, after the promotion push button open closed insurance institution, can operate close handles and firing handle parts and drive the linear type cutting element.
After adopting technique scheme, tissue is excessive in having avoided performing the operation, and can thoroughly sew up and cut and organize through once-through operation; Use this linear type Endo-GIA; Pollute but maximum possible reduces in the art, clinical manipulation is simple and practical, and is more welcome than traditional anastomat.
