Description
Technical field
The present invention relates to a kind of surgical operating instrument, be in particular a kind of Linear seam cutting device, belong to technical field of medical instruments.
Background technology
Linear seam cutting device is widely used in sewing up and cutting for wound suture, interior tissue in surgical operation, typical Linear seam cutting device discloses as U.S. Pat 5129570, have and sew up and two functions of cutting, in carrying out wound suture, by unnecessary cutting tissue.Such Linear seam cutting device generally comprises upper and lower two clamps, and for the closed handle of the upper and lower clamp of closure, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, be located in nail bin and percussion sheet and the cutting knife that can move relative to described nail bin simultaneously, and push button for driving described percussion sheet and cutting knife to move.In described nail bin, be disposed with suturing nail, described percussion sheet promotes in order successively pushing slice of nail and pushes suturing nail to nail anvil, and described cutting knife cuts off the tissue between nail bin and nail anvil.
Being connected of closed handle on existing Linear seam cutting device and nail bin frame is to rely on bearing pin and be enclosed within that bearing pin cap outside bearing pin pivots together, wherein, bearing pin cap is by spot-welded on nail bin frame bottom surface, and bearing pin is through pin shaft hole corresponding in closed handle.Owing to sometimes there being spot welding situation not in place in welding process, and then it is firm not to make closed handle be connected with nail bin frame, apparatus is in the time opening, if elastic force is larger, the sudden outburst of its elastic force will certainly make acceleration increase, so not only can cause the discomfort of user, and easily cause falling apart of apparatus to be fallen.
Summary of the invention
The object of the invention is to propose a kind of surgical operating instrument simple in structure, by the improvement to structure, apparatus can slowly be opened, and syndeton is also comparatively firm, is difficult for falling apart and falls.
Object of the present invention, will be achieved by the following technical programs:
A kind of surgical operating instrument, comprise the nail anvil and the nail bin that are oppositely arranged, described nail anvil outer surface is fixedly installed nail anvil shell, described nail bin is located in a nail bin frame, described nail bin frame and closed handle are pivotally connected, and described nail bin frame is connected by buffer gear with described closed handle, and described buffer gear comprises housing and is arranged in housing and the rotating shaft rotating relative to housing, described housing is fixedly connected with described nail bin frame, and described rotating shaft is relative with described closed handle to be fixedly connected with.
Preferably, described buffer gear is an antivibrator, and is provided with resisting medium between described rotating shaft and described housing.
Preferably, described antivibrator is mechanical type antivibrator or electromagnetic damper.
Preferably, described mechanical type antivibrator is hydraulic damper or viscous damper.
Preferably, described resisting medium is damping fluid.
Preferably, described resisting medium is elastic colloid.
Preferably, described elastic colloid is spring or torsion spring or felt.
Beneficial effect of the present invention is mainly reflected in: closed handle is connected with nail bin frame by buffer gear, connects also comparatively firm.When apparatus is in the time opening, closed handle is through the relative nail bin frame of buffer gear Unscrew, and its opening action is comparatively mild, make apparatus be difficult for falling apart and fall, and the use feel of user is also better.
Accompanying drawing explanation
Fig. 1 is the structural representation of surgical operating instrument of the present invention.
Fig. 2 is the structure enlarged diagram of buffer gear in the present invention.
Wherein: 1, nail anvil; 2, nail bin; 3, nail anvil shell; 4, nail bin frame; 5, housing; 6, rotating shaft; 7, snap fit; 8, closed handle.
The specific embodiment
Surgical operating instrument as shown in Figure 1, consistent with prior art, comprise the nail anvil 1 and the nail bin 2 that are oppositely arranged, described nail anvil 1 outer surface is provided with nail anvil shell 3, on described nail anvil shell 3, be provided with the snap fit 7 for clamping nail anvil 1, described snap fit is 1 group or many groups of symmetric arrays, generally adopts 1 group of snap fit to coordinate the location of carrying out nail anvil end.Described nail bin 2 is located in a nail bin frame 4, and described nail bin frame 4 is connected with closed handle 8.
Shown in Fig. 2, described nail bin frame 4 is connected by buffer gear with described closed handle 8, buffer gear described in this preferred embodiment is an antivibrator, described antivibrator comprises housing 5 and is arranged in housing 5 and the rotating shaft 6 rotating relative to housing, described housing 5 is fixedly connected with described nail bin frame 4, described rotating shaft 6 is fixedly connected with described closed handle 8, between described rotating shaft 6 and described housing 5, be provided with resisting medium, when buffer gear is antivibrator action, rotating shaft 6 drives closed handle 8 to rotate relative to nail bin frame 4 with respect to the rotation of housing 5, slowly open.
In the present invention, described antivibrator is mechanical type antivibrator or electromagnetic damper.Preferably, described antivibrator can adopt hydraulic damper or viscous damper, described resisting medium be can be medical damping fluid.Or described resisting medium can also be elastic colloid, adopts elastic damper, the felt that wherein elastic colloid also can be spring, torsion spring or cooperatively interacts, as long as can make the housing of antivibrator and the material that rotating shaft produces relative rotation.
In this preferred embodiment, the housing of antivibrator is fixed on nail bin frame, can weld together, the rotating shaft of antivibrator is fixedly connected with closed handle, when after the release-push of pressing on apparatus, the rotating shaft of antivibrator produces relative motion with respect to the housing of antivibrator, thereby drives closed handle to rotate relative to nail bin frame, realizes apparatus and gently opens.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection scope of the present invention.
