Embodiment 1
[0040] see figure 1 and image 3 , the natural orifice endoscopic surgery assisting device 1 includes a support rod 10, a fixed block 20, a slider 30 and at least three first elastic pieces 40, wherein the fixed block 20 is fixed on one end of the support rod 10, and the slider 30 sets Set on the support rod 10, and the slider 30 can reciprocate along the support rod 10, at least three first elastic pieces 40 are distributed at intervals, and the first end of each first elastic piece 40 is hinged with the fixed block 20, so that the first The first end of the elastic piece 40 can rotate around the direction perpendicular to the axis of the support rod 10, that is, the hinge shaft at which the first end of the first elastic piece 40 is hinged with the fixed block 20 is perpendicular to the axis of the support rod 10, and each first elastic piece 40 The second end of the first elastic piece 40 is hinged with the slider 30, so that the second end of the first elastic piece 40 ca...
Embodiment 2
[0046] see figure 2 and image 3 , the auxiliary device for endoscopic surgery through the natural orifice provided in this embodiment is basically the same as that of Embodiment 1, the main difference is that the auxiliary device for endoscopic surgery through the natural orifice 1 also includes a first connecting block 50, a second connecting block 60 and the second elastic piece 70, wherein the first connecting block 50 is sleeved on the support rod 10, and is arranged at intervals on the side of the fixing block 20 close to the slider 30, that is, between the first connecting block 50 and the fixing block 20 The position between them is relatively fixed; the second connection block 60 is sleeved on the support rod 10, and is arranged at intervals on the side of the slider 30 close to the fixed block 20, that is, the position between the second connection block 60 and the slider 30 Relatively fixed, the second connecting block 60 can move back and forth along the support ...
Embodiment 3
[0052] see Figure 4 , the auxiliary device for endoscopic surgery through the natural orifice provided in this embodiment is basically the same as that in Embodiment 2, the main difference is that the auxiliary device for endoscopic surgery through the natural orifice 1 also includes a connecting rod 80 and a shaft sleeve 90, and the connecting rod 80 replaces the first connecting rod 500, and the shaft sleeve 90 replaces the second connecting rod 600, that is, the first end of the connecting rod 80 is connected with the fixed block 20, the second end of the connecting rod 80 is firmly connected with the first connecting block 50, and the shaft The sleeve 90 is sleeved on the support rod 10, and one end of the shaft sleeve 90 is fastened and rotatably connected to the slider 30, and the other end of the shaft sleeve 90 is fastened and rotatably connected to the second connecting block 60. the other one.
[0053] Further, in this embodiment, only the first motor is provided o...
