Detailed Description
Example 1:
this embodiment is shown in fig. 1 to 8.
As shown in fig. 1, the present embodiment provides an anastomat with a firing indication mechanism, part a in fig. 1 is the firing indication mechanism, and the anastomat includes a housing, as shown in fig. 2, the firing indication mechanism includes a firing indication pull tab assembly 1, a firing indication component 2, a rotation stopping block 3, a screw 4, a firing indication window 5, and a firing indication spring 6. The firing indication pull tab assembly 1 can enable the firing indication mechanism to operate accurately and work reliably.
As shown in fig. 3, the above-mentioned trigger indication pulling-on piece assembly 1 is composed of a trigger indication pulling-on piece 11 and a trigger indication pulling-on piece 12, one end 121 of the above-mentioned trigger indication pulling-on piece 12 is connected with one end 111 of the above-mentioned trigger indication pulling-on piece 11, one end 121 of the above-mentioned trigger indication pulling-on piece 12 is welded with one end 111 of the above-mentioned trigger indication pulling-on piece 11. As shown in fig. 6, the firing indication member 2 includes a firing indication baffle 21, and the other end 122 of the firing indication spring 12 is connected to the firing indication baffle 21 in contact therewith. The entire firing indication mechanism including the firing indication spring 12 ensures the accuracy of the firing indication in the reciprocating motion. The trigger indication spring 12 and the trigger indication baffle 21 are mutually extruded to force the trigger indication pull tab 11 to be in close contact with the eccentric shaft of the trigger indication, so that the rotation of the trigger indication is ensured to be synchronous with the movement of the trigger indication pull tab 11, and the phenomenon of delay defect of the trigger indication and the movement of the trigger indication pull tab 11 is avoided.
As shown in fig. 2 and 7, the rotation stopping block 3 is fixed on the screw 4, the other end of the firing indication pull tab 11 passes through the firing indication spring 6 and is connected with the housing, as shown in fig. 7, the firing indication pull tab 11 is clamped with the rotation stopping block 3, as shown in fig. 2, and the rotation stopping block 3 drives the firing indication pull tab 11 to move up and down through up and down movement on the screw 4.
As shown in fig. 2, the firing indication mechanism further includes a firing indication window 5, and the firing indication window 5 and the firing indication member 2 are mounted on the housing.
As shown in fig. 4, 5 and 6, the above-mentioned firing indication component 2 further includes a firing indication eccentric shaft 22, a firing indication line 23 and a firing indication central shaft 24, the above-mentioned firing indication pulling piece 11 which moves makes the above-mentioned firing indication component 2 rotate around the above-mentioned firing indication central shaft 24, when the above-mentioned firing indication line 23 moves into the above-mentioned firing indication window 5, it prompts the above-mentioned anastomat to fire. The above-mentioned firing indication member 2 has a hemispherical shape.
As shown in fig. 8, the firing indication tab 11 is formed in a right angle shape, and the right angle 113 of the right angle shape is engaged with the firing indication eccentric shaft 22.
The trigger indication spring 12 always makes the trigger indication pull tab assembly 1 in close contact with the trigger indication eccentric shaft 22 and the trigger indication baffle 21.
The trigger indication spring 12 and the trigger indication baffle 21 are pressed against each other to bring the trigger indication tab 11 into close contact with the trigger indication eccentric shaft 22, so that the rotation of the trigger indication member 2 is synchronized with the movement of the trigger indication tab 11.
The anastomat is a tubular anastomat, a linear cutting anastomat, a endoscopic cutting anastomat, an arc-shaped anastomat, a linear anastomat, a circumcision anastomat or a skin anastomat.
The working process of the firing instruction is as follows:
the above-mentioned firing indication member 2 moves downward, i.e. in a direction approaching the knob 7 of the above-mentioned stapler shown in fig. 1, and the following "downward movement" is also a movement approaching the knob 7 of the above-mentioned stapler shown in fig. 1:
in the first step, the screw 4 drives the rotation stop block 3 to move downward, and the firing indication pull tab 11 is driven by the rotation stop block 3 to move downward.
And secondly, pulling the firing indication eccentric shaft 22 when the firing indication pulling piece 11 moves downwards to enable the firing indication component 2 to rotate around the firing indication central shaft 24. At the same time, the trigger indication spring 12 and the trigger indication baffle 21 are mutually extruded to force the trigger indication pull tab 11 to be in close contact with the trigger indication eccentric shaft 22, so that the rotation of the trigger indication component 2 is synchronous with the motion of the trigger indication pull tab 11, and the phenomenon of motion delay defect of the trigger indication component 2 and the trigger indication pull tab 11 is avoided.
Third, when the above-mentioned firing indication part 2 moves to a certain angle, the indication line 23 of the above-mentioned firing indication enters into the visible window of the above-mentioned firing indication window 5, at this time the apparatus enters into the cockable state. And selecting different positions according to different surgical positions to perform instrument firing.
The above-mentioned firing indicator piece 2 moves upward, i.e., in a direction approaching the decorative tube 8 of the above-mentioned stapler shown in fig. 1, and the following "upward movement" is also a movement approaching the decorative tube 8 of the above-mentioned stapler shown in fig. 1:
during use of the instrument, when the instrument is over-run, i.e. the indication line 23 of the firing indication is too far down, the instrument needs to be retracted to a specified required position, and then the firing indication member 2 needs to be moved upwards.
The first step: the screw 4 drives the rotation stop block 3 to move upwards, and the firing indication pull tab 11 moves upwards under the restoring force of the firing indication spring 6.
And a second step of: when the trigger indication pull tab 11 moves upward, the trigger indication spring 12 pushes the trigger indication baffle 21 to rotate the trigger indication member 2 back, thereby completing the retraction function of the trigger indication wire 23. During the retraction process, the trigger indication pull tab 11 always ensures that the trigger indication pull tab 11 is in close contact with the trigger indication eccentric shaft 22 and the trigger indication baffle 21 under the action of the trigger indication spring 12. Therefore, the phenomenon that the movement of the trigger indicating component 2 lags behind the trigger indicating pull piece 11 in the retreating process due to the fit clearance between the trigger indicating pull piece 11 and the trigger indicating component 2 is avoided, namely, when the trigger indicating pull piece 11 moves upwards, the trigger indicating pull piece 11 is not contacted with the trigger indicating component 2 in the retreating process due to the clearance between the trigger indicating pull piece 11 and the trigger indicating component 2, so that the trigger indicating component 2 moves behind the trigger indicating pull piece 11, and finally, the trigger indication is inaccurate.
And a third step of: when the firing indicator line is retracted to the desired position, the instrument may be fired.
The above-mentioned firing indication mechanism ensures the accuracy of the firing indication in the reciprocating motion. The firing indicating mechanism of the anastomat provided by the embodiment of the invention has the advantages of simple structure, high reliability and high indicating precision.
