[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] like Figure 1 As shown, the cervical conization traction device includes a hollow rod body 1, an adjusting rod 2 disposed in the rod body 1, a plurality of traction clamps 3 disposed at one end of the rod body 1, and an adjusting knob 4 disposed at the other end of the rod body 1; one end of the traction clamps 3 is connected to the rod body 1, and the other end is connected to the adjusting rod 2; one end of the adjusting rod 2 is connected to the traction clamps 3, and the other end is screwed into the adjusting knob 4; the adjusting knob 4 is rotatably disposed at one end of the rod body 1.

[0028] In this embodiment, please refer to Figure 4 and Figure 5 When the tension clamp 3 is not under force, it is initially U-shaped. When the adjusting rod 2 extends outward from the rod body 1, it causes the tension clamp 3 to tend to be straight. When the adjusting rod 2 retracts inward from the rod body 1, it causes the tension clamp 3 to gradually bend back to the initial U-shape.

[0029] To better secure the traction effect, the number of traction clips 3 is 4 to 6. Please refer to... Figure 1Preferably, in this embodiment, the number of traction clips 3 is four, and the four traction clips 3 are arranged at equal intervals around the axis of the rod (1). In other embodiments, the number of traction clips 3 may be six or eight, which is not limited here.

[0030] In this embodiment, the traction clamp 3 and the adjusting rod 2 are connected by a hinge. Specifically, the traction clamp 3 and the adjusting rod 2 are connected by a hinge, and the traction clamp 3 and the rod body 1 can also be fixed by a hinge. The hinged connection facilitates the replacement of the traction clamp 3 and makes maintenance easier.

[0031] In this embodiment, the traction clamp 3 is made of a titanium alloy with elasticity and shape memory. For example, a nickel-titanium alloy with shape memory capability can be used. The traction clamp 3, with its good elasticity, can change its shape as the adjusting rod 2 moves, and its shape memory allows it to return to its original shape without irreversible deformation leading to damage. The use of titanium alloy allows for repeated sterilization and reuse, reducing medical costs.

[0032] In this embodiment, the rod body 1 includes a marking part 11 and a grip part 12. The marking part 11 is marked with scales, and the grip part 12 is provided with anti-slip texture.

[0033] In this embodiment, the marking section 11 includes multiple marking segments, each 2 cm in length. Starting from the top of the rod 1, each 2 cm segment is marked with a different color to facilitate quick identification by the doctor. For example, the 0-20 mm section is blue, the 21-40 mm section is green, the 41-60 mm section is yellow, and the 61-80 mm section is orange. The multiple marking segments on the marking section 11 use a striking contrasting color design to accurately mark the distance from the exposed cervix to the internal cervical os, thereby indirectly providing the doctor with a reference for the conization depth. The striking marking segments allow the doctor to more clearly and accurately grasp the traction depth, thus more precisely controlling the conization depth and improving the accuracy and safety of the surgery.

[0034] like Figure 2 and 3 As shown, in this embodiment, the adjusting knob 4 includes a threaded portion 41 and an adjusting portion 42. The threaded portion 41 extends into and is rotatably engaged with the rod body 1, while the adjusting portion 42 is located outside the rod body 1. One end of the adjusting rod 2 has a thread that engages with the threaded portion 41. By rotating the adjusting portion 42, the adjusting rod 2 can move axially within the rod body 1. The rod body 1 is provided with a slot 13 for engaging the adjusting knob 4, and the threaded portion 41 is provided with a retaining ring 43. The adjusting knob 4 is rotatably engaged with the rod body 1.

[0035] In this embodiment, the rod body 1, the adjusting rod 2, and the adjusting knob 4 are made of stainless steel or titanium alloy. The all-metal cervical conization traction device ensures that all components can be repeatedly sterilized and reused, greatly reducing medical costs while avoiding problems such as the fragility and potential residue issues associated with silicone balloons.

[0036] The specific operation of this cervical conization auxiliary traction device is as follows: The doctor holds the cervical conization auxiliary traction device and rotates the adjustment knob 4's adjustment part 42. The adjustment rod 2 moves outward from the rod body 1, causing the traction clamping flap 3 to extend upward. Figure 5 The diagram shows the state after the traction flap 3 is extended upwards. At this time, the cervical conization auxiliary traction device can be easily inserted into the cervix.

[0037] Slowly insert the extended and opened traction flap 3 into the internal cervical os;

[0038] After the traction flap 3 reaches the bottom of the uterus, the adjusting part 42 is rotated in the opposite direction, and the adjusting rod 2 retracts inward to the rod body 1, thereby causing the traction flap 3 to gradually close and retract to its original shape, so that the traction flap 3 fits tightly against the inner wall of the cervical os, completing the fixation. The distance the adjusting rod 2 moves can be adjusted according to different cervical shapes, so that the shape of the traction flap 3 fits more closely against the inner wall of the cervical os, greatly improving the stability of traction and reducing unexpected situations during the operation.

[0039] The doctor observes the scale markings on the marking section 11 on the rod 1 to ensure that the insertion depth of the cervical conization auxiliary traction device is appropriate. Then, the doctor slowly pulls the cervical conization auxiliary traction device outward to pull the cervix to the appropriate position. After clamping, the doctor can perform the cervical conization surgery. During the operation, the cervical conization auxiliary traction device can stably pull the cervix, providing a good operating field for the operation.
