The front end of the whole anastomat is sent to the intestinal tract part to be removed and sutured, the front end of the whole anastomat can be slowly expanded within the range of the elastic coefficient of the intestinal tract when the front end of the anastomat advances in the human body under the action of the spherical boss 311 arranged at the top end of the pushing shell 31 of the front end actuating mechanism 3 of the anastomat, the resistance of the anastomat when the anastomat moves in the human body is reduced, the front end actuating mechanism 3 and the rear end actuating mechanism 4 of the anastomat can be easily sent to the appointed diseased part, the front end of the whole anastomat is sent to the diseased part and then is pulled back for a short distance, the front end actuating mechanism 3 of the anastomat stays in the original position under the elastic action of the intestinal tract, the rear end actuating mechanism 4 backs back for a certain distance, the front end actuating mechanism 3 and the rear end actuating mechanism 4 are separated for a certain distance, and the diseased part which needs to be excised and sutured is positioned between the front end actuating mechanism 3 and the rear end actuating mechanism 4, the intestinal wall of the affected part naturally contracts between the front end executing mechanism 3 and the rear end executing mechanism 4 due to the elasticity of the intestinal tract, and the preparation work of excision suture is completed.

Because the blade mounting groove 313 of the pushing shell 31 of the front end actuator 3 is internally and movably provided with the annular blade 32, the inner side surface of the annular blade 32 is provided with four wedge-shaped sliding blocks 321 corresponding to the sliding block grooves 314, the steel cable fixing holes 3212 of the wedge-shaped sliding blocks 321 are internally and fixedly provided with the steel cable fixing rings 341 of the pull steel cable 34, so that the whole annular blade 32 can be driven to move in the blade mounting groove 313 by pulling the pull steel cable 34, the bottom end of the pull steel cable 34 is provided with the conversion steel cable 342, the conversion steel cable 342 is fixedly connected with the connecting steel cable 24, and the other end of the connecting steel cable 24 is fixedly connected with the steel cable fixing groove 1521 at the top end of the steel cable pull rod 152, so that the movement of the annular blade 32 can be controlled by the operating mechanism 1.

After the doctor determines the position to be cut, the doctor can further reduce the false pressing probability of the doctor when cutting off the suture by pressing the trigger 13 quickly, because the slide limit plate 131 arranged at the top end of the trigger 13 is arranged inside the shell 11, the force to the trigger 13 can be transmitted to the trigger transmission rod 153 of the cutting excitation mechanism 15 through the trigger transmission rod mounting hole 132, because the trigger transmission rod 153 penetrates through the trigger transmission rod fixing plug 1514, the two ends of the trigger spring 1531 are respectively welded and fixed with the trigger transmission rod 153 and the trigger transmission rod fixing plug 1514, and the movement transmitted through the trigger transmission rod 153 needs to use larger force to enable the trigger 13 to move under the action of the trigger spring 1531.

The movement of the trigger transmission rod 153 pushes the bottom end of the steel cable pulling rod 152 to move, so that the whole steel cable pulling rod 152 rotates around the fixed rotating shaft 1511, the inner wall of the fixed housing 151 is located above the fixed rotating shaft 1511 and provided with an arc limiting groove 1512, and the spring limiting lock pin 154 is arranged inside the bottom end of the steel cable pulling rod 152, so that the movement of the whole steel cable pulling rod 152 is performed under the common limiting action of the spring limiting lock pin 154 and the arc limiting groove 1512, when the spring limiting lock pin 154 moves to a certain position in the arc limiting groove 1512, the spring limiting lock pin 154 enters the lock hole 1513 arranged at the bottom end of the arc limiting groove 1512 under the action of the lock pin spring 1541, the position of the whole steel cable pulling rod 152 is locked, and the movement of all the steel cables is limited.

Because the whole process of quickly pressing the trigger 13 is extremely short, the top end of the cable pulling rod 152 moves quickly in the whole process, and then the connecting steel cable 24 fixed in the steel cable fixing groove 1521 and the stretching steel cable 34 move quickly, the annular blade 32 slides out from the blade mounting groove 313 under the action of the stretching steel cable 34 to cut off the affected part quickly, after the cutting off is finished, the annular blade 32 continues to move quickly under the action of the stretching steel cable 34 and enters the blade accommodating groove 412, and under the action of the spring fixing block 42, when the annular blade 32 enters the blade accommodating groove 412, the fixing spring 422 is compressed under the interaction of the sliding inclined surface 3211 arranged at the bottom end of the wedge-shaped sliding block 321 and the fixing inclined surface 32111 arranged at the top end of the wedge-shaped fixing block 421, so that the whole annular blade 32 enters the bottom end of the blade accommodating groove 412 through the spring fixing block 42, and after the annular blade 32 completely enters, the fixing spring 422 of the spring fixing block 42 is no longer acted by force to return to the initial state, and the spring fixing block 42 blocks the corresponding position of the blade accommodating groove 412, so that the annular blade 32 is completely limited in the blade accommodating groove 412, and the annular blade 32 is prevented from being exposed outside and easily causing secondary injury to a patient.

After the cutting step is completed, the rear end actuator 4 is pushed towards the front end actuator 3 by the trigger handle 12 of the operating mechanism 1, the part to be sutured is clamped between the front end actuator 3 and the rear end actuator 4 due to the elasticity of the intestinal tract, then the starting ring 162 on the safety air valve switch 161 arranged at the bottom end of the high-pressure air tank 16 is rotated to the opening position, the compressed air in the high-pressure air tank 16 is sent into the main vent pipe 22 through the safety air valve switch 161, the compressed air in the high-pressure air tank 16 is sent into the corresponding shunt pipe 233 of the shunt vent pipe 23 through the main vent pipe 22 and the transition wide pipe 231 due to the communication between the main vent pipe 22 and the shunt vent pipe 23 through the transition wide pipe 231, and is sent into the catapult mounting groove 432 through the communication groove 433 arranged at the bottom end of the suture outer pipe 43, and the inside of the catapult mounting groove 432 of the catapult 44 is rapidly moved through the air pressure of the compressed air, so that a plurality of staple push rods 441 arranged at the top end of the ejector stapler 44 quickly impact staples 45 in the staple slots 431, so that the staples 45 pierce the intestinal wall under the action of sharp tips, and are bent in the staple bending slots 331 on the corresponding anvil 33 to suture the intestinal tract, and the suturing step is completed.

After the suturing step is completed, under the elastic action of the intestinal wall, and because a movable telescopic rod is arranged between the front end executing mechanism 3 and the rear end executing mechanism 4, the front end executing mechanism 3 and the rear end executing mechanism 4 are connected, the front end of the whole anastomat entering the human body is slowly withdrawn from the device through the exciting grab handle 12 of the operating mechanism 1, so that the rear end executing mechanism 4 can be synchronously withdrawn from the front end executing mechanism 3 through the linkage mechanism 2, the whole excision suturing work is completed, and the treatment process is finished.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
