Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

As shown in fig. 1 and 2, a teaching surgical forceps includes: the clamp comprises a movable handle 1, a displacement cylinder 3, a fixed handle 5, a rotary knob 6, an external fixed sleeve connecting piece 7, an external fixed piece 8, an iron clamp main body 9 and a hardware circuit board 12; an external fixed sleeve connecting piece 7 is arranged on the right side of the rotary knob 6; an outer fixing piece 8 is arranged on the right side of the outer fixing sleeve connecting piece 7; the iron clamp main body 9 sequentially penetrates through the rotary knob 6, the outer fixed sleeve connecting piece 7 and the outer fixed piece 8; the iron clamp main body 9 is fixedly connected with the rotary knob 6; a hardware circuit board 12 is arranged in the fixed handle 5; a displacement cylinder 3 is arranged at the middle front end of the fixed handle 5; a movable handle 1 is arranged at the middle rear end of the fixed handle 5; the rear end of the iron clamp main body 9 passes through the center of the displacement cylinder 3 and extends to the middle rear end of the fixed handle 5 to be movably connected with the movable handle 1.

Further, a first sensor circuit 2 and a second sensor circuit 4 are welded to the upper end of the hardware circuit board 12; a circuit connection point 11 is arranged at the bottom of the hardware circuit board 12; the lines on the hardware circuit board 12 are led out through the circuit connection points 11.

Further, a magnetic sensor placement position 10 is provided on the inner side wall of the outer fixture 8.

Further, a groove 13 is arranged at the upper end of the movable handle 1; a slotted hole 14 is arranged at the front end of the groove 13; the rear end of the iron clamp main body 9 passes through the slotted hole 14 and is arranged in the groove 13; and a sliding block 15 is arranged on the iron clamp main body 9 in the groove 13, and the sliding block 15 is connected with the groove 13 in a sliding manner.
