Each model apparatus of existing apparatus is applicable to a kind of stitching and cutting of tissue of thickness, when surgical, suitable apparatus model to be selected according to the thickness of surgical tissue, like this concerning hospital and doctor, usually to be the apparatus of the standby multiple model of operation, with the demand of different-thickness tissue various in satisfied operation.
Summary of the invention
Object of the present invention solves the problems of the technologies described above, a kind of medical linear seam cutter with clamp governor motion is proposed, this governor motion can after seam cutter be closed, according to the seaming and cutting thickness adjusted clamp spacing of tissue, thus tissue thickness is adapted with nail forming height, stitching and cutting that an apparatus is applicable to multi-thickness tissue can be realized, stock difficulty and the warehousing pressure of hospital can be reduced.
Object of the present invention, will be achieved by the following technical programs:
A kind of medical linear seam cutter, comprising: the upper and lower clamp that can mutually close or open, is oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, and for closing the closed handle of upper and lower clamp; Described nail bin surface is provided with several nail along the arrangement of apparatus axis, is provided with the pushing slice of nail and suturing nail that mutually abut in each nail; The middle part of described upper clamp is provided with clamp governor motion, and described governor motion comprises two cam pins of forward and backward setting and controls the rotating bars of cam pin rotation.
Preferably, the upper surface of described upper clamp offers groove, and described rotating bars is placed in 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 periphery, middle part of described cam pin is provided with the tooth bar be meshed with rotating bars groove, and described rotating bars is forward and backward movement in groove, and drives two cam pin motions.
Preferably, described rotating bars offers kidney slot, be equipped with one in described kidney slot for fixing the steady pin of upper 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 is convexly equipped with the ripple glaze for promoting rotating bars movement.
Preferably, the eccentric phase difference of two described cam pins is 180 °.
Beneficial effect of the present invention is mainly reflected in: by changing the gap of nail anvil and nail bin, and then changing the pretightning force of seam cutter far-end, realizing the object of regulating nail forming height; Make a kind of apparatus of model can adapt to stitching and the cutting of the tissue of multi-thickness, facilitate doctor and hospital.

Detailed description of the invention
Present invention is disclosed a kind of medical linear seam cutter, as shown in Figure 1-Figure 3, comprising: the upper and lower clamp that can mutually close or open, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, and for closing the closed handle of upper and lower clamp; Described nail bin surface is provided with several nail along the arrangement of apparatus axis, is provided with the pushing slice of nail and suturing nail that mutually abut in each nail.
The middle part of described upper clamp is provided with clamp governor motion, and described governor motion comprises two cam pins of forward and backward setting and controls the rotating bars 11 of cam pin rotation; Described cam pin is respectively the locking pin 12 being arranged on rotating bars 11 front end, is arranged on the fulcrum pin 13 of rotating bars 11 rear end.
As shown in Figure 2, the upper surface of described upper clamp offers groove 1, is provided with rotating bars 11 in groove 1, the forward and backward movement in groove of described rotating bars 11.Described rotating bars 11 offering kidney slot 21, being equipped with one in described kidney slot 21 for fixing the steady pin 22 of upper clamp and rotating bars 11 position.The displacement of the forward and backward movement of described rotating bars 11 is suitable with kidney slot length.
Two cam pins are all 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 periphery, middle part of described cam pin is provided with the tooth bar 32 be meshed with the groove 31 of rotating bars 11, mobile drive two cam pin motions of rotating bars 11.
Conveniently rotating bars 11 moves forward and backward, and prevent from skidding, the upper surface of described rotating bars is convexly equipped with the ripple glaze 41 for promoting rotating bars movement.
Preferably, the eccentric phase difference of two described cam pins is 180 °, and shown in composition graphs 4, namely when rotating bars 11 moves to foremost with rearmost end, then one of them cam pin peaks 34 places, and another cam pin touches the bottom 33 places.The gap clearance amplitude of variation between upper and lower clamp so just can be made maximum.
Below in conjunction with operating process under Brief Description Of Drawings.
When being added into nail anvil and the nail bin of upper and lower clamp far-end until seaming and cutting tissue, Linear seam cutting device closes, now, if the thickness of tissue is comparatively large, then regulate clamp governor motion, concrete by stirring rotating bars 11, stir forward, the gap smaller of nail anvil and nail bin; Stir, the gap of nail anvil and nail bin becomes large backward.By regulating upper clamp front end to carry out the slow finishing clamping and close, making a kind of apparatus of model can adapt to stitching and the cutting of the tissue of multi-thickness, facilitating doctor and hospital.In order to make adjustment more meet the expected requirements, can be provided with Warning Mark on the surface of seam cutter, Warning Mark for color instruction or can adopt electronical display, in order to show the gap clearance between upper and lower clamp.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
