Abstract
The utility model discloses a surgical operation instrument which comprises a pin anvil and a pin bin which is arranged opposite to the pin anvil, a pin anvil outer shell is fixedly arranged on the outer surface of the pin anvil, the pin bin is arranged inside a pin bin frame which is connected with a closed handle in a pivot mode, and the pin bin frame is connected with the closed handle through a buffering mechanism. The buffering mechanism comprises a shell and a rotary shaft, wherein the rotary shaft is arranged inside the shell and can rotate relative to the shell which is fixedly connected with the pin bin frame, and the rotary shaft is fixedly and oppositely connected with the closed handle. According to the surgical operation instrument, the buffering mechanism is arranged between the closed handle and the pin bin frame, the instrument can be opened slowly, connection is firmer, falling apart and falling off will not occur easily, and meanwhile comfort of a user is improved.
Description
Technical field
This utility model relates to a kind of surgical operating instrument, is in particular a kind of linear type seaming and cutting device, belongs to technical field of medical instruments.
Background technology
Linear type seaming and cutting device is widely used in being used in the surgical operation wound suture, interior tissue is sewed up and cutting, typical linear type seaming and cutting device such as US Patent No. 5129570 announcement, have and sew up and two functions of cutting, when carrying out wound suture, excess tissue is excised.Such linear type seaming and cutting device generally comprises upper and lower two clamps, and the closed handle that is used for closed upper and lower clamp, be oppositely arranged on nail anvil and the nail bin of upper and lower clamp far-end, be located in the nail bin and percussion sheet and the cutting knife that can move relative to described nail bin simultaneously, and for driving the push button that described percussion sheet and cutting knife move.Be disposed with suturing nail in the described nail bin, described percussion sheet promotes pushing slice of nail successively in order and pushes suturing nail to nail anvil, and described cutting knife cuts off the tissue between nail bin and nail anvil.
Closed handle on the existing linear type seaming and cutting device is to rely on the bearing pin bearing pin medicated cap outer with being enclosed within bearing pin to pivot together with being connected of nail bin frame, wherein, on nail bin frame bottom surface, bearing pin passes pin shaft hole corresponding on the closed handle to the bearing pin medicated cap by spot-welded on.Owing in welding process, there is spot welding situation not in place sometimes, and then it is firm inadequately to make that closed handle is connected with the nail bin frame, apparatus is when opening, if elastic force is bigger, the unexpected release of its elastic force will certainly make acceleration increase, so not only can cause the discomfort of user, and cause falling apart of apparatus to be fallen easily.
The utility model content
The purpose of this utility model is to propose a kind of surgical operating instrument simple in structure, by the improvement to structure, make apparatus slowly to open, and syndeton is also comparatively firm, is difficult for falling apart and falls.
The purpose of this utility model 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 set with the nail anvil shell, described nail bin is located in the 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, the rotating shaft that described buffer gear comprises housing and is arranged in the housing and rotates relative to housing, described housing is fixedlyed connected with described nail bin frame, and described rotating shaft is connected with described closed handle relative fixed.
Preferably, described buffer gear is an antivibrator, and is provided with resisting medium between described rotating shaft and the 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 of the utility model are mainly reflected in: closed handle is connected with the nail bin frame by buffer gear, connects also comparatively firm.When apparatus when opening, closed handle is through the relative nail bin frame of buffer gear Unscrew, its opening action is comparatively mild, make apparatus be difficult for falling apart and fall, and the use feel of user is also better.
Description of drawings
Fig. 1 is the structural representation of this utility model surgical operating instrument.
Fig. 2 is the structure enlarged diagram of buffer gear in this utility model.
Wherein: 1, nail anvil; 2, nail bin; 3, nail anvil shell; 4, nail bin frame; 5, housing; 6, rotating shaft; 7, trip; 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, described nail anvil shell 3 is provided with the trip 7 for clamping nail anvil 1, described trip is 1 group or many group of symmetric arrays, generally adopts 1 group of trip to cooperate the location of carrying out the nail anvil end.Described nail bin 2 is located in the nail bin frame 4, and described nail bin frame 4 is connected with closed handle 8.
In conjunction with shown in Figure 2, described nail bin frame 4 and described closed handle 8 are connected by buffer gear, buffer gear described in this preferred embodiment is an antivibrator, the rotating shaft 6 that described antivibrator comprises housing 5 and is arranged in the housing 5 and rotates relative to housing, described housing 5 is fixedlyed connected with described nail bin frame 4, described rotating shaft 6 is fixedlyed connected with described closed handle 8, be provided with resisting medium between described rotating shaft 6 and the described housing 5, when buffer gear is the antivibrator action, rotating shaft 6 drives closed handle 8 relative nail bin frame 4 rotations with respect to the rotation of housing 5, slowly opens.
In this utility model, 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.Perhaps, described resisting medium can also be elastic colloid, namely adopts elastic damper, and as long as the elastic colloid felt that also can be spring, torsion spring or cooperatively interact wherein is can be so that the material that the housing of antivibrator and rotating shaft produce relative rotation.
In this preferred embodiment, the housing of antivibrator is fixed on the nail bin frame, can weld together, the rotating shaft of antivibrator is fixedlyed connected with closed handle, behind the release-push of pressing on the apparatus, the rotating shaft of antivibrator produces relative motion with respect to the housing of antivibrator, thereby drives the relative nail bin frame rotation of closed handle, and the realization apparatus is gently opened.
This utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within the protection domain of the present utility model.
