Summary of the invention
Purpose of the present invention solves the problems of the technologies described above, a kind of medical linear seaming and cutting device with clamp governor motion is proposed, this governor motion can be after seaming and cutting device closure, according to distance between the seaming and cutting thickness adjusted clamp of tissue, thereby make tissue thickness and nail forming height adapt, can realize that an apparatus is fit to stitching and the cutting of multiple thickness tissue, can reduce stock difficulty and the warehousing pressure of hospital.
Purpose of the present invention will be achieved by the following technical programs:
A kind of medical linear seaming and cutting device comprises: can be mutually the closed or upper and lower clamp opened, be oppositely arranged on 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; Described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and the suturing nail of mutual butt in each nail hole; Described middle part of going up clamp is provided with the clamp governor motion, and described governor motion comprises two cam pins of forward and backward setting and controls the rotating bars that cam pin rotates.
Preferably, the described upper surface of going up clamp offers groove, and described rotating bars places in the groove, and described cam pin is arranged in the middle part of clamp.
Preferably, the front and back ends lower surface of described rotating bars is provided with groove, and the middle part outer periphery of described cam pin is equipped with the tooth bar that is meshed with the rotating bars groove, and described rotating bars is forward and backward movement in groove, and drives two cam pin motions.
Preferably, offer kidney slot on the described rotating bars, be equipped with one in the described kidney slot and be used for the fixing steady pin of going up clamp and rotating bars position, the displacement of the forward and backward movement of described rotating bars is suitable with kidney slot length.
Preferably, the upper surface of described rotating bars convexes with for promoting the ripple glaze that rotating bars moves.
Preferably, the eccentric phase contrast of two described cam pins is 180 °.
Beneficial effect of the present invention is mainly reflected in: by 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 stitching and the cutting of the tissue of multiple thickness, make things convenient for doctor and hospital.

The specific embodiment
The present invention has disclosed a kind of medical linear seaming and cutting device, as shown in Figure 1-Figure 3, comprising: can be mutually the closed or upper and lower clamp opened, be oppositely arranged on 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; Described nail bin surface is arranged along the apparatus axis and is provided with several nail holes, is provided with pushing slice of nail and the suturing nail of mutual butt in each nail hole.
Described middle part of going up clamp is provided with the clamp governor motion, and described governor motion comprises two cam pins of forward and backward setting and controls the rotating bars 11 that cam pin rotates; Described 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 described upper surface of going up clamp offers groove 1, is provided with rotating bars 11 in the groove 1, the forward and backward movement in groove of described rotating bars 11.Offer kidney slot 21 on the described rotating bars 11, be equipped with one in the described kidney slot 21 and be used for the fixing steady pin 22 of going up clamp and rotating bars 11 positions.The displacement of described rotating bars 11 forward and backward movements is suitable with kidney slot length.
Two cam pins all are arranged in the middle part of clamp.The front and back ends lower surface of described rotating bars 11 is provided with groove 31, and the middle part outer periphery of described cam pin is equipped with the tooth bar 32 that is meshed with the groove 31 of rotating bars 11, two cam pins motions of the mobile drive of rotating bars 11.
