When the first switch 32 is triggered, the switch assembly 30 is in the first state, and at this time, the cutter assembly moves forward, and when the second switch 33 is triggered, the control board 35 controls the first switch 32 to reset or turn off, so that the switch assembly 30 is in the second state, and at this time, the cutter assembly moves backward. Preferably, the first switch 32 and the second switch 33 are micro switches, however, the first switch 32 and the second switch 33 include, but are not limited to, pressure sensors and the like.
The driving member 34 is disposed at the opening of the receiving cavity and is used for triggering the first switch 32 and the second switch 33. The driving member 34 is in a key shape, in order to facilitate triggering, the driving member 34 is partially embedded in the accommodating cavity, the driving member 34 is provided with a pressing surface facing the outside, the pressing surface is a curved surface, the middle position of the pressing surface is recessed towards the first switch 32 and the second switch 33, and the positions of the pressing surface corresponding to the first switch 32 and the second switch 33 are both arranged in a protruding manner, so that the triggering positions of the first switch 32 and the second switch 33 can be distinguished. Preferably, in order to facilitate the driving member 34 to smoothly trigger the first switch 32 and the second switch 33, the driving member 34 is pivotally connected to the base 31 via a rotating shaft (not shown), the rotating shaft is disposed at a middle position of the first switch 32 and the second switch 33, and the first switch 32 and the second switch 33 are mirror-symmetrical about the rotating shaft.
The driving member 34 is provided with a first abutting portion 341 and a second abutting portion 342 protruding toward the first switch 32 and the second switch 33, respectively, the first abutting portion 341 protruding toward the first switch 32, and the second abutting portion 342 protruding toward the second switch 33, and preferably, the first abutting portion 341 and the second abutting portion 342 are symmetrically provided with respect to the driving member 34. When the driving member 34 rotates around the rotation axis, the driving member 34 is in the first state, the first abutting portion 341 moves toward the first switch 32, and the outer side of the end of the first abutting portion 341 abuts against the first switch 32, and when the driving member 34 rotates around the rotation axis to the other side, the driving member 34 is in the second state, the second abutting portion 342 moves toward the second switch 33, and the outer side of the end of the second abutting portion 342 abuts against the second switch 33.
Note that, the distance between the first switch 32 and the second switch 33 is set to be large, the distance between the first contact portion 341 and the second contact portion 342 is equal to the distance between the first switch 32 and the second switch 33, and the distance between the rotation shaft and the edge on the outer side of the distal end of the first contact portion 341 is equal to or greater than the distance between the rotation shaft and the first switch 32, and similarly, the distance between the rotation shaft and the edge on the outer side of the distal end of the second contact portion 342 is equal to or greater than the distance between the rotation shaft and the second switch 33 on the side corresponding to the second switch 33 because the first switch 32 and the second switch 33 are mirror-symmetric. Of course, it is understood that when the driver 34 is in the first state, only the first switch 32 is abutted by the first abutting portion 341 and the second switch 33 is not abutted by the second abutting portion 342, and likewise, when the driver 34 is in the second state, only the second switch 33 is abutted by the second abutting portion 342 and the first switch 32 is not abutted by the first abutting portion 341. In particular, the first abutment 341 extends towards the first switch 32 for a length greater than the distance between the first switch 32 and the second switch 33, and the second abutment 342 extends towards the second switch 33 for a length greater than the distance between the first switch 32 and the second switch 33, in such a way as to reduce the angle of rotation required by the driver 34 by lengthening the first abutment 341 and the second abutment 342, with the spacing between the first switch 32 and the second switch 33 being between 6 and 12 mm. The four values of the distance between the first switch 32 and the second switch 33, namely 6mm, 7.5mm, 9.5mm and 12mm, are respectively selected to test the use condition of the anastomat, and the result shows that a better use effect can be obtained; the situation that the pressing is not good or the two ends are not switched well is not found in the using process, and the hand feeling is good.
Preferably, the driving member 34 is further provided with a first elastic member 321 and a second elastic member 331, the first elastic member 321 and the second elastic member 331 are preferably springs, the first elastic member 321 is disposed between the first switch 32 and the first abutting portion 341, two ends of the first elastic member 321 are respectively sleeved on the first abutting portion 341 and the first switch 32, the second elastic member 331 is disposed between the second switch 33 and the second abutting portion 342, two ends of the second elastic member 331 are respectively sleeved on the second abutting portion 342 and the second switch 33, the first elastic member 321 and the second elastic member 331 are symmetrically disposed with respect to the driving member 34, the first abutting portion 341 can abut against the first switch 32 through the first elastic member 321, the second abutting portion can abut against the second switch 33 through the second elastic member 331, and the first elastic member 321 and the second elastic member 331 can restore the driving member 34 after rotation.
In particular, the driver 34 is configured to have the third state, and since the first elastic member 321 and the second elastic member 331 are arranged in mirror symmetry, when the driver 34 is not subjected to an external force, the forces of the first elastic member 321 and the second elastic member 331 on the driver 34 are equal, the driver 34 is in a balanced state in the third state, the first abutting portion 341 does not abut against the first switch 32, and the second abutting portion 342 does not abut against the second switch 33. Of course, in another embodiment of the present invention, the driving member 34 further has a fourth state, in this embodiment, the driving member 34 is slidably connected to the base 31 through the guiding structure, so that the driving member 34 can simultaneously abut against the first switch 32 and the second switch 33 after being pressed, that is, the first abutting portion 341 abuts against the first switch 32, and the second abutting portion 342 abuts against the second switch 33, so as to prevent accidental contact in an accidental situation.
Further, the electric stapler 100 further includes a third switch, which can be used to adjust the cartridge assembly and rotate the cartridge assembly left and right. Of course, the third switch includes, but is not limited to, a switch assembly 30 for locking, or a mode of the switch assembly 30 for changing, so that the switch assembly 30 can be used to adjust and rotate the cartridge assembly left and right, which can be specifically set as required, and is not limited herein.
In summary, the present invention has two switches with shorter travel on the control board 35, and by increasing the distance between the two switches, the rotation angle of the driving member 34 is reduced, and meanwhile, the two sides of the driving member 34 are provided with elastic structures to prevent accidental touch.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
