In the present invention, however, the following recognition mechanism is employed;
as shown in fig. 10-15: the recognition mechanism comprises a connecting part 503 arranged at the tail part of the cutting component 1 and a control board 514 with a contact switch 513 arranged in the gun body component 2;
the length of the connecting part 503 of any two cutting assemblies 1 is different; the number of the contacts on the contact switch 513 is not less than the number of the types of the cutting assemblies 1;
the gun body component 2 is also provided with a sliding contact block 511 which slides back and forth, and the tail part of the sliding contact block 511 is provided with a pressure spring 512 so that the sliding contact block 511 is always kept in a state of being separated from a contact switch 513;
when the cutting assembly 1 is installed on the gun body assembly 2, the connecting part 503 triggers the sliding contact block 511 to move backwards, so that the sliding contact block 511 is contacted with the contact switch 513;
the cutting assemblies 1 of different types trigger the sliding contact block 511 to complete different strokes; so that the sliding contact blocks 511 are different in the number of contacts with the contact switches 513.
The core of the recognition mechanism is that the cutting assembly 1 is matched with connecting parts 503 with different lengths according to the model and specification, and a contact switch 513 is arranged in the gun body assembly 2 and is matched with a sliding contact block 511 which is contacted with the contact switch 513. Because the connecting parts 503 of the cutting assemblies 1 of different models have different lengths, the sliding degree of the trigger sliding contact block 511 is different, and the number of contacts contacted by the sliding contact block 511 and the contact switch 513 is different; finally, the model of the cutting assembly 1 is judged according to the contact number of the sliding contact block 511 and the contact switch 513.
It is contemplated that a slide slot may be provided in the body assembly in which the sliding contact block 511 slides back and forth. And the control board 514 is mounted within the gun body assembly 2.
It should be noted that the gun body assembly 2 is divided into a gun rod part and a gun body main body at the front end, and the gun rod part comprises a gun rod outer tube assembly 521, an anastomosis pushing rod 523 and an identification pushing slide block 522;
the anastomosis push rod 523 is connected with the gun body main body, the identification push slider 522 is slidably mounted on the anastomosis push rod 523, and the gun rod outer tube component 521 is sleeved on the peripheries of the anastomosis push rod 523 and the identification push slider 522;
when the cutting assembly 1 is arranged at the front end of the gun rod outer tube assembly 521, the cutting assembly 1 is connected with the anastomosis push rod 523, so that the gun body main body 21 can control the cutting assembly 1; meanwhile, the connecting portion 503 of the cutting assembly 1 pushes the pushing slider 522 by pushing, so as to drive the sliding contact block 511 to move backward.
In addition, during installation, the sliding contact block 511 is installed in the gun body assembly, and then the compression spring 512 is installed, wherein the sliding contact block 511 performs telescopic translation movement in a sliding groove of the gun body assembly through the compression spring 512, the initial state is the maximum ejection state, namely the sliding contact block is always kept in a state of being separated from the contact switch, the contact switch 513 is fixed on the control board 514, and the control board 514 is fixed in the gun body assembly.
The specific principle is as follows: after the cutting assembly 1 of a specific model is pushed into the gun body assembly 2, the connecting part 503 in the cutting assembly 1 pushes the identification pushing slider 522 in the gun rod assembly to perform backward translation movement, the identification pushing slider 222 pushes the sliding contact block 511 in the gun body main body to translate backward, and the sliding contact block 511 contacts and presses the contact switch 513 in the backward translation process. Because the depth distance of the cutting assembly 1 inserted into the gun body assembly 2 is the exposed length of the connecting part 503, and the exposed lengths of the connecting parts in the cutting assemblies 1 of different models are different, the translation distance of the connecting part 503 pushing the sliding contact block 511 is also different, as a result, the number of contacts on the contact switch 513 touched by the sliding contact block 511 is also different, and finally, the cutting assemblies 1 of different length models are prepared to be identified according to the number of contacts on the contact switch 513.
The primary identification module here is generally a primary grating 71 and the secondary identification module is a shading column 72.
Certainly, according to the requirement, considering the requirement that the product needs to be initially positioned, a positioning identification module is further arranged; the positioning identification module is fixedly arranged in the gun body component 2; the positioning identification module corresponds to the appointed secondary identification module and determines the initial position of the transmission mechanism.
The positioning identification module is typically a positioning grating 73.
Generally, the main identification module and the positioning grating 73 are connected to the micro control unit, and after generating a signal with the designated shading post 72, the driving mechanism is controlled to stop moving, and the cutting is completed, and it should be noted that the position between the main identification module and the sub identification module can be changed, see fig. 18 specifically.
As shown in fig. 16 and 17: a control method of a linear cutting anastomat with controllable cutting stroke,
it comprises the following steps:
step 1: installing a cutting assembly 1 with a specific model on the gun body assembly 2, and identifying the model of the cutting assembly by an identification mechanism and feeding back information to the micro control unit;
step 2: starting the gun body assembly 2 for excitation, and driving the transmission mechanism to advance so as to drive the cutting knife to advance;
