Abstract
Present invention is disclosed a kind of surgical operating instrument, including the nail anvil being oppositely arranged and nail bin, 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 is pivotally connected with closed handle, described nail bin frame is connected by buffer gear with described closed handle, described buffer gear includes housing and is arranged at interior and housing into rotation relatively the rotating shaft of housing, described housing is fixing with described nail bin frame to be connected, and described rotating shaft is relatively fixed with described closed handle and is connected.The present invention by arranging buffer gear between closed handle and nail bin frame so that apparatus can slowly be opened, and connects also comparatively firm, not easily falls apart and falls, improves the comfort level of user simultaneously.
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 surgical operation to sew up and cutting for wound suture, interior tissue, typical Linear seam cutting device such as US Patent No. 5129570 is disclosed, there are two functions of stitching and cutting, while carrying out wound suture, by unnecessary cutting tissue.Such Linear seam cutting device generally comprises upper and lower two clamps, and for closing the closed handle of upper and lower clamp, it is oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, the percussion sheet being located in nail bin and can simultaneously move relative to described nail bin and cutting knife, and the push button for driving described percussion sheet and cutting knife to move.Being disposed with suturing nail in described nail bin, described percussion sheet promotes pushing slice of nail successively in order and suturing nail is pushed to nail anvil, and described cutting knife will be located in the tissue between nail bin and nail anvil and cuts off.
The connection of the closed handle on existing Linear seam cutting device and nail bin frame is dependent on bearing pin and what the bearing pin cap that is enclosed within outside bearing pin pivoted together, and wherein, bearing pin cap is by spot-welded on nail bin frame bottom surface, and bearing pin is the pin shaft hole of correspondence in closed handle.The situation not in place owing to occasionally there are spot welding in welding process, and then it is firm not that closed handle can be made to be connected with nail bin frame, apparatus is when opening, if elastic force is bigger, suddenly the release of its elastic force will certainly make acceleration increase, so not only result in the discomfort of user, and also be easily caused falling apart of apparatus and fall.
Summary of the invention
The purpose of the present invention is to propose to the surgical operating instrument of a kind of simple in construction, by the improvement to structure so that apparatus can slowly be opened, and attachment structure is also comparatively firm, not easily falls apart and falls.
The purpose of the present invention, will be achieved by the following technical programs:
A kind of surgical operating instrument, including the nail anvil being oppositely arranged and nail bin, 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 is pivotally connected with closed handle, and described nail bin frame is connected by buffer gear with described closed handle, and described buffer gear includes housing and is arranged at interior and housing into rotation relatively the rotating shaft of housing, described housing is fixing with described nail bin frame to be connected, and described rotating shaft is relatively fixed with described closed handle and is connected.
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.
The beneficial effects are mainly as follows: closed handle is connected with nail bin frame by buffer gear, connects also comparatively firm.When apparatus is when opening, the relative nail bin frame Unscrew of the buffered mechanism of closed handle, its opening action is comparatively mild so that apparatus not easily falls apart and falls, and the use feel of user is also better.

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.
Detailed description of the invention
Surgical operating instrument as shown in Figure 1, consistent with prior art, including the nail anvil 1 being oppositely arranged and nail bin 2, described nail anvil 1 outer surface is provided with nail anvil shell 3, described nail anvil shell 3 is provided with the snap fit 7 for clamping nail anvil 1, described snap fit is 1 group or many groups of symmetric arrays, is generally adopted 1 group of snap fit and coordinates the location 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 includes housing 5 and is arranged at interior and housing into rotation relatively the rotating shaft 6 of housing 5, described housing 5 is fixing with described nail bin frame 4 to be connected, described rotating shaft 6 is fixing with described closed handle 8 to be connected, it is provided with resisting medium between described rotating shaft 6 and described housing 5, when buffer gear and antivibrator action, rotating shaft 6 drives closed handle 8 to rotate relative to nail bin frame 4 relative to the rotation of housing 5, slowly opens.
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 to be damping fluid that can be medical.Or, described resisting medium can also be elastic colloid, namely adopts elastic damper, and wherein elastic colloid is alternatively spring, torsion spring or the felt cooperated, as long as can so that the material that produces relative rotation of the housing of antivibrator and rotating shaft.
In this preferred embodiment, the housing of antivibrator is fixed on nail bin frame, can be welded together, the rotating shaft of antivibrator and the fixing connection of closed handle, when after the release button pressed on apparatus, the rotating shaft of antivibrator produces relative motion relative to the housing of antivibrator, thus driving closed handle to rotate relative to nail bin frame, it is achieved apparatus is gently opened.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of being formed, all falls within protection scope of the present invention.
