DETAILED DESCRIPTION

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0017] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Figure 1-Figure 3 The schematic diagram of the whole structure of the device for preventing tumor spread in laparoscopic cervical cancer surgery of the present invention is shown. Figure 1-Figure 3 The device for preventing tumor spread during laparoscopic cervical cancer surgery of this embodiment includes an operating rod 10 with a hollow interior, an adjusting rod 20 is installed and sleeved at the front end of the operating rod 10, a swing rod 30 extending outward is arranged at the center of the front end of the inner side of the adjusting rod 20, and the interior of the swing rod 30 is through at both ends, a suction cover 301 connected to the swing rod 30 is fixed at the front end of the swing rod 30, and the front end of the suction cover 301 is open, and the rear end of the swing rod 30 is connected to a suction tube 70 extending to the outside of the rear end of the operating rod 10, and the operating rod 10 has symmetrically arranged slide grooves 101 on both sides near the rear end, and a slider 50 slides inside the slide groove 101, and the operating rod 10 has finger pressure blocks 501 with one end fixed on the slider 50 on both sides, and the operating rod 10 has traction guide wires 60 respectively connected to the corresponding sliders 50 on both sides of the interior, and the other ends of the corresponding traction guide wires 60 are respectively connected to the two sides of the middle part of the swing rod 30.

[0020] The operating rod 10, the adjusting rod 20 and the suction hood 301 are all circular structures, and the outer walls between the operating rod 10 and the adjusting rod 20 are connected by a plane. Here, the longer operating rod 10 can facilitate the doctor to insert the device and the front adjusting rod 20 and the suction hood 301 into the patient's abdominal cavity, and the depth can be controlled according to actual needs. At the same time, the outer contour of the device is circular, so that it can be rotated and the angle of the entire rod body can be adjusted at will during use without causing discomfort and pain to the patient's body, thereby improving the patient experience during surgical treatment.

[0021] The rear end of the operating rod 10 also has a pressure handle 102 whose diameter is larger than the outer diameter of the operating rod 10. The central part of the pressure handle 102 also has an avoidance hole 102a that is opened to one side and corresponds to the suction tube 70. The setting of the pressure handle 102 can effectively increase the contact area between the rear end of the operating rod 10 and the doctor's palm, and at the same time, the operational stability of the device is further improved under the reaction force of the finger pressure blocks 501 on both sides; in addition, the avoidance hole 102a can facilitate the connection of the other end of the suction tube 70 to a negative pressure suction device such as a negative pressure bag or a negative pressure aspirator, so as to suck out and remove the tumor fragments.

[0022] Guide sleeves 201 movably mounted on the outside of the traction guide wire 60 are also fixed on both sides of the inner wall of the adjustment rod 20. Through the set guide sleeves 201, the traction guide wire 60 can pull the swing rod 30 at a larger inclination angle, making the swing rod 30 swing left and right more smoothly.

[0023] The rear end of the rocker arm 30 also has a connector 302 that is detachably connected to the end of the suction tube 70. In the present embodiment, the operating rod 10 and the adjusting rod 20 are snap-fitted together. When the operating rod 10 and the adjusting rod 20 are disassembled, the suction tube 70 and the connector 302 can be conveniently docked and disassembled, which is simple and practical.

[0024] In this embodiment, during laparoscopic cervical cancer resection surgery, the doctor can operate the adjustment rod 20 and the swing rod 30 located inside the patient's abdominal cavity through the operating rod 10, and by toggling any one of the finger pressure blocks 501 on both sides, the swing rod 30 and the suction cover 301 are driven to twist to one side with the cooperation of the traction guide wire 60 and the guide sleeve 201. At the same time, the doctor can cooperate to rotate the operating rod 10 so that the suction port of the suction cover 301 can accurately and flexibly correspond to the location of the fragments, and at the same time, the negative pressure suction device is turned on, and negative pressure suction is formed on the swing rod 30 and the suction cover 301 through the suction tube 70, so that the myoma fragments are sucked away. The operation is simple and easy to use, so that the device effectively reduces the recurrence rate and the risk of iatrogenic dissemination and implantation after surgical treatment of cervical cancer, brings convenience to patients and medical personnel, and is conducive to the early recovery of patients.

[0025] In summary, in the device for preventing tumor spread during laparoscopic cervical cancer surgery of this embodiment, during laparoscopic cervical cancer resection surgery, the doctor can operate the adjustment rod 20 and the swing rod 30 located inside the patient's abdominal cavity through the operating rod 10, and by toggling any one of the finger pressure blocks 501 on both sides, the swing rod 30 and the suction cover 301 are driven to twist to one side with the cooperation of the traction guide wire 60 and the guide sleeve 201. At the same time, the doctor can cooperate to rotate the operating rod 10 so that the suction port of the suction cover 301 can accurately and flexibly correspond to the location of the fragments, and at the same time, turn on the negative pressure suction device, and form negative pressure suction on the swing rod 30 and the suction cover 301 through the suction tube 70, so as to suck and remove the tumor fragments.

[0026] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
