Specific embodiment
Technical scheme of the present invention is further elaborated with reference to the accompanying drawings and detailed description.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of cutter device of stapler, cutter device include cutting cutting for tissue
Knife, the power source that power is provided for cutter cutting, the transmission mechanism that power source and cutter machinery are sequentially connected, transmission mechanism tool
Have the first use state and the second use state, cutter device further include for by transmission mechanism switch to the first use state or
The switching mechanism of second use state, when transmission mechanism is switched to the first use state, and power source drive passes by switching mechanism
During dynamic mechanism kinematic, transmission mechanism drives cutter to perform cutting work, when transmission mechanism is switched to the second use by switching mechanism
State, and during the movement of power source drive transmission mechanism, transmission mechanism drives cutter to perform backoff operation and simultaneously cutter retracts to first
Beginning position.
Specifically, transmission mechanism includes the setting slided along the front-rear direction of stapler and the transmission being sequentially connected with cutter
Rack 3, the setting around Pivot Point Center line rotation and the driving gear 1 that can be engaged with driving rack 3 and around Pivot Point Center line
The setting of rotation and the driven gear 2 that setting is intermeshed with driving gear 1, driven gear 2 can be nibbled with 3 phase of driving rack
It closes, in this example, when transmission mechanism is switched to the first use state by switching mechanism, driving gear 1 is meshed with driving rack 3,
And at this time driven gear 2 and driving rack 3 without engaging connection；When power source drive driving gear 1 rotates, driving gear 1 drives
Driving rack 3 travels forward, and then cutter is driven to perform cutting work；In addition, when transmission mechanism is switched to the by switching mechanism
Two use states, driven gear 2 is meshed with driving rack 3 and driving gear 1 is disengaged from driving rack 3；Power source drives
When dynamic driving gear 1 rotates, driving gear 1 drives driven gear 2 to rotate backward, and driven gear 2 drives driving rack 3 to transport backward
It is dynamic, and then cutter is driven to perform backoff operation.
Further, switching mechanism includes driving gear 1 or driven gear 2 is pushed to cut with what driving rack 3 was disengaged from
It changes button 4, tend to the return mechanism being meshed with promotion driving gear 1 or driven gear 2 with driving rack 3.And 4 He of switch bar
Return mechanism is located at corresponding two side positions of axial direction of driving gear 1 or driven gear 2 respectively.In this example, return mechanism includes dividing
It does not offset with driving gear 1 and driven gear 2 and respectively driving gear 1 and driven gear 2 provides the first of elastic-restoring force
51 and second elastic component 52 of elastic component.
Moreover, it relates to a kind of stapler, stapler further includes work head 10, operation handle 30, is connected to work
Make the cutter device that connecting rod 20, trigger device and the present invention between first 10 and operation handle 30 are described, cutter device
In driving gear 1 and driven gear 2 rotation be set on operation handle 30 in, driving rack 3 slide be set on operation handle 30 with
It is that trigger device includes the being connected in operation handle 30 of rotation and is connected with driving gear 1 and tactile in connecting rod 20
Send out trigger 6.
To sum up, the cutter device of stapler of the invention by being equipped with for driving gear and driven gear, is passing
When motivation structure is switched to the first working condition, driving gear is engaged with driving rack（Driven gear and driving rack are without engaging）,
So as to which driving gear rotation can drive driving rack to travel forward, cutter performs cutting work；Is switched in transmission mechanism
During two working conditions, driven gear is engaged with driving rack（Driving gear is disengaged from driving rack）, so as to driving gear
Rotation can drive driven gear to invert, and cutter is finally made to perform backoff operation；In addition, the stapler of the present invention passes through the cutting
The setting of device effectively solves the inconvenience that both hands is needed to operate, and also reduces the action width of cutter device rollback operation
Degree, increases the accuracy of surgical procedure, and shorten operating time, mitigates patient's pain, improves procedure efficiency and effect；Together
When the present invention stapler also avoid the setting of exposed withdrawing device so that the appearance intensity and aesthetics of entire stapler
It effectively improves.
The present invention is described in detail above, its object is to allow the personage for being familiar with this field technology that can understand this
The content of invention is simultaneously implemented, and it is not intended to limit the scope of the present invention, and the present invention is not limited to above-mentioned implementations
Example, the equivalent change or modification that all Spirit Essences according to the present invention are made should be covered by the protection scope of the present invention.
