In one possible embodiment of the present application, as shown in fig. 1 and 2, the adjusting mechanism 130 includes a connecting rod 131 disposed within the sleeve 110 and having a distal end thereof engaged with the second magnetic ring 150, the proximal end of the connecting rod 131 being connected to an operating portion 160, the operating portion 160 including a knob 161 threadedly connected to the connecting rod 131, and rotating the knob 161 to adjust the position of the second magnetic ring 150 relative to the first magnetic ring 120.
Specifically, when the position of the second magnetic ring 150 relative to the first magnetic ring 120 needs to be adjusted, the knob 161 is turned to move the connecting rod 131 relative to the knob 161, and the connecting rod 131 moves towards or away from the knob 161 to drive the second magnetic ring 150 to move towards or away from the first magnetic ring 120 through the connecting rod 131.
For example, when the knob 161 is rotated clockwise, the connecting rod 131 moves towards the knob 161, and the connecting rod 131 drives the second magnetic ring 150 to move towards the first magnetic ring 120, and when the knob 161 is rotated counterclockwise, the connecting rod 131 moves away from the knob 161, and the connecting rod 131 drives the second magnetic ring 150 to move away from the first magnetic ring 120. When the rectal stapler 100 is used to connect a rectal incision, the second magnetic ring 150 is first connected to the distal rectum outside the body, then put back in the body, the connecting rod 131 is extended to the longest by rotating the knob 161 counterclockwise, the distal end of the sleeve 110 is extended into the incision, the proximal rectum is connected to the first magnetic ring 120, and then the knob 161 is rotated clockwise to move the second magnetic ring 150 toward the first magnetic ring 120 until the second magnetic ring 150 reaches a magnetic attraction distance from the first magnetic ring 120.
In one possible embodiment of the present application, as shown in fig. 1 and 2, the magnetic ring detachment mechanism 140 includes a push rod 141 disposed within the sleeve 110, and the operating portion 160 further includes a handle 162 rotatably coupled to the sleeve 110 through a first rotation shaft, and rotates the handle 162 toward the sleeve 110 to control detachment of the first magnetic ring 120 from the sleeve 110.
Specifically, when the first magnetic ring 120 and the second magnetic ring 150 reach the magnetic attraction distance, then the handle 162 is pressed to rotate towards the sleeve 110, the push rod 141 moves towards the first magnetic ring 120, so that the first magnetic ring 120 is pushed towards the second magnetic ring 150 by the push rod 141, during the pushing process, the first magnetic ring 120 is separated from the sleeve 110, the second magnetic ring 150 is separated from the connecting rod 131, and then the handle 162 is driven to rotate away from the sleeve 110, so that the push rod 141 is reset. At this time, the sleeve 110 is taken out, and the first magnetic ring 120 and the second magnetic ring 150 remain in the body for a while and then are discharged out of the body along with the necrotic intestinal.
In one possible embodiment of the present application, as shown in fig. 1 and 2, the sleeve 110 is rotatably connected with a limiting member 163 through a second rotation shaft, and the limiting member 163 can abut against the handle 162 to limit the handle 162 from rotating toward the sleeve 110.

Therefore, when the position of the second magnetic ring 150 relative to the first magnetic ring 120 is adjusted, the rotation limiting member 163 abuts against the first magnetic ring 120, so as to ensure that the handle 162 cannot rotate at this time, the first magnetic ring 120 cannot be separated from the sleeve 110, and after the first magnetic ring 120 and the second magnetic ring 150 reach the magnetic attraction distance, the limiting member 163 is rotated to separate the handle 162 from the abutment against the limiting member 163, and at this time, the handle 162 is pressed to separate the first magnetic ring 120 from the sleeve 110, and the second magnetic ring 150 is separated from the connecting rod 131.

In one possible embodiment of the present application, as shown in fig. 1 and 2, a reset 1621 is also provided between the handle 162 and the cannula 110.

Specifically, the position of the indicator 132 is observed through the observation window to observe the position of the second magnetic ring 150 relative to the first magnetic ring 120, so as to ensure that the first magnetic ring 120 and the second magnetic ring 150 reach the magnetic attraction distance.
When the knob 161 is rotated, the connecting rod 131 moves towards or away from the knob 161, and at this time, the connecting rod 131 drives the second magnetic ring 150 to move relative to the first magnetic ring 120, so that the position of the indicator 132 can be observed through the observation window, and the position of the second magnetic ring 150 relative to the first magnetic ring 120 can be accurately known.
When the rectal anastomat 100 is used to connect a rectal incision, the second magnetic ring 150 is firstly connected with the distal rectum outside the body, then put back into the body, the connecting rod 131 is extended to the longest by rotating the knob 161 anticlockwise, the distal end of the sleeve 110 is extended into the incision, the proximal rectum is connected with the first magnetic ring 120, then the knob 161 is rotated clockwise to enable the second magnetic ring 150 to move towards the first magnetic ring 120 until the second magnetic ring 150 reaches the magnetic attraction distance with the first magnetic ring 120, the position of the indicator 132 is observed through the observation window, and the position of the second magnetic ring 150 relative to the first magnetic ring 120 is ensured to reach the magnetic attraction distance, so that the magnetic ring detachment mechanism 140 can be ensured to detach the second magnetic ring 150 from the first magnetic ring 120 simultaneously, and the distal rectum is communicated with the proximal rectum.
After the second magnetic ring 150 and the first magnetic ring 120 reach the magnetic attraction distance through the observation window, the limiting piece 163 is rotated to separate the handle 162 from the abutting of the limiting piece 163, and at this time, the handle 162 is pressed to separate the first magnetic ring 120 from the sleeve 110, and the second magnetic ring 150 magnetically attracted to the first magnetic ring 120 is also separated from the connecting rod 131.
Further, a scale bar is disposed on the observation window, so as to observe whether the second magnetic ring 150 reaches the magnetic attraction distance relative to the first magnetic ring 120 through the scale bar.
