The purpose of this utility model will be achieved through following technical scheme:
A kind of medical linear seaming and cutting device comprises: can be each other the closed or upper and lower clamp opened, be oppositely arranged on the nail anvil and the nail bin of upper and lower clamp far-end and the closed handle that is used for closed upper and lower clamp; Said nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with the pushing slice of nail and the suturing nail of mutual butt in each nail hole; Said middle part of going up clamp is provided with the clamp governor motion, and said governor motion comprises two cam pins of forward and backward setting and controls the rotating bars that cam pin rotates.
Preferably, the said upper surface of going up clamp offers groove, and said rotating bars places in the groove, and said cam pin is arranged in the middle part of clamp.
Preferably, the front and back ends lower surface of said rotating bars is provided with groove, and the middle part outer periphery of said cam pin is equipped with the tooth bar that is meshed with the rotating bars groove, and said rotating bars is forward and backward moving in groove, and drives two cam pin motions.
Preferably, offer kidney slot on the said rotating bars, be equipped with in the said kidney slot one be used for fixing clamp and rotating bars position steady pin, the forward and backward mobile displacement of said rotating bars is suitable with kidney slot length.
Preferably, the upper surface of said rotating bars convexes with and is used to promote the ripple glaze that rotating bars moves.
Preferably, the eccentric phase contrast of two said cam pins is 180 °.
The beneficial effect of this utility model is mainly reflected in: through the gap of change nail anvil and nail bin, and then the pretightning force of change seaming and cutting device far-end, realize regulating nail molding purpose highly; Make a kind of apparatus of model can adapt to the stitching and the cutting of the tissue of multiple thickness, make things convenient for doctor and hospital.

The specific embodiment
This utility model has disclosed a kind of medical linear seaming and cutting device, like Fig. 1-shown in Figure 3, comprising: can be closed each other or the upper and lower clamp opened, be oppositely arranged on the nail anvil and the nail bin of upper and lower clamp far-end, and the closed handle that is used for closed upper and lower clamp; Said nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with the pushing slice of nail and the suturing nail of mutual butt in each nail hole.
Said middle part of going up clamp is provided with the clamp governor motion, and said governor motion comprises two cam pins of forward and backward setting and controls the rotating bars 11 that cam pin rotates; Said cam pin is respectively the locking pin 12 that is arranged on rotating bars 11 front ends, is arranged on the fulcrum pin 13 of rotating bars 11 rear ends.
As shown in Figure 2, the said upper surface of going up clamp offers groove 1, is provided with rotating bars 11 in the groove 1, and said rotating bars 11 is forward and backward moving in groove.Offer kidney slot 21 on the said rotating bars 11, be equipped with in the said kidney slot 21 one be used for fixing clamp and rotating bars 11 positions steady pin 22.Said rotating bars 11 forward and backward mobile displacements are suitable with kidney slot length.
