With reference to fig. 1 and 2: the pull rope 5 passes through all the end part rope threading holes 21, and the end parts pass through the center of the framework driving assembly and the outer operating rod 1, namely two tail parts of the pull rope 5 are positioned at the rear end of the outer operating rod 1. When the framework 2 is in a contraction state, the front end of the framework 2 is contracted by the pull rope 5. A middle stringing hole 22 is further provided at the center of the frame 2 for guiding the pulling rope 5 so that the pulling rope 5 is attached to the frame 2 as much as possible. The pulling rope 5 passes through all the end part threading holes 21 and then passes through the two frameworks 2 which are arranged at intervals to enter the inside of the fixed seat 6. Thus, the forces acting on the four end threading holes 21 by the pulling rope 5 are balanced, and the phenomenon that the framework 2 inclines to one side does not occur.
The "front end" and the "rear end" in the present embodiment refer to an end close to the end threading hole 21 and an end held by a user, respectively, and are determined by the angle of the user during normal use.
The framework 2 is bent towards the axial center of the external operating rod 1 by no more than 90 degrees in a natural state, wherein 90 degrees refers to radian, namely when the framework 2 is not subjected to external force, the framework is slightly bent inwards, but the bending degree is no more than 1/4 of a circle.

As shown in fig. 5: it should be noted that: the front end and the rear end of the front positioning groove 13 and the front end of the rear positioning groove 14 are provided with transition arcs which can pass through the locking sheet 42; this transition arc allows the inner locking piece 42 to be moved out again by the axial force of the inner operating lever 4 without locking the relative position between the inner operating lever 4 and the outer operating lever 1, but in order to avoid the inner operating lever 4 from being directly pulled out from the rear end of the outer operating lever 1, the rear end of the rear positioning groove 14 is vertically configured and does not have the transition arc described above. Thus, the function of rear end limiting can be achieved.
When the external operation rod is used, the front end of the external operation rod 1 is moved to a tumor to be cut off when the framework 2 is in a storage state, the framework 2 and the flexible bag 3 are stored in the external operation rod 1, so that the framework and the flexible bag can be inserted into a small hole, the external diameter of the external operation rod 1 can be about 1 cm, and the external operation rod can be applied to minimally invasive surgery.
After the front end of the external operating rod 1 is moved to the tumor to be cut, the internal operating rod 4 is pushed forward relative to the external operating rod 1, when the locking piece 42 enters the front positioning groove 13, the locking of the axial position of the internal operating rod 4 in the external operating rod 1 can be realized, at this time, the fixing seat 6 extends out of the front end of the external operating rod 1, the internal operating rod 4 is rotated (the locking piece 42 can slide in the front positioning groove 13 and provide damping convenient to control), the core tube 8 rotates synchronously with the internal operating rod 4, the threaded section 81 moves towards the relatively shallow direction of the internal driving piece 7 through the threaded fit between the threaded section 81 and the internal driving piece 7, namely, the internal driving piece 7 is pushed through the core tube 8, because the fixing seat 6 is limited by the stop block 12 at the front end, the internal driving piece 7 moves forward relative to the fixing seat 6, the framework 2 is unfolded towards the opening direction through the fit of the rack 71 and the gear 23, and when the framework 2 is unfolded to a certain angle, the side part of the framework 2 can be limited by the front end surface of the external operating rod 1. The skeletons 2 can not be further opened, the rotation of the inner operating rod 4 is stopped, and at the moment, the four skeletons 2 support the flexible bag 3 into a hemispherical state, which is similar to an umbrella structure.
When the uterus is cut off, the framework 2 is controlled by the pull rope 5 and the inner operating rod 4 to tightly grasp the vagina, so that the tumor is prevented from overflowing when the vagina is cut. After the vagina is broken, the front end of the framework 2 can be further reduced, so that the flexible bag 3 forms a cavity with a closed front end as much as possible, and the excised tumor is positioned in the flexible bag 3, and the tumor diffusion can be avoided.
Compared with the prior art, the embodiment can form a sealed cavity through the framework 2 and the flexible bag 3, so that the tumor entering the interior of the flexible bag is protected by the flexible bag 3, and the tumor is prevented from being spread.
When the framework 2 is in the storage state, all the frameworks 2 and the flexible bags 3 can be completely stored in the outer operating rod 1, so that the outer operating rod 1 can be conveniently inserted into the body of a patient and extends to an affected part, and the outer operating rod 1 can be applied to minimally invasive surgery due to the fact that the outer diameter of the outer operating rod 1 is small.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
