The top of the positioning column 528 is fixedly connected with a rectangular block 5210. The bottom of the rectangular block 5210 is slidably connected with the top of the lifting block 524. By arranging the puncture assembly 52, when the puncture position of the patient's abdominal cavity is adjusted, the operator first inserts the puncture needle 529 into the inside of the through slot 525, so that the outer wall of the positioning column 528 is attached to the inner wall of the bearing ring 526. Then the fixed ring 527 is attached to the top of the bearing ring 526 by pressing the positioning column 528 downward, so as to install the puncture needle 529. After the puncture needle 529 is installed, the operator starts the driving motor 521, so as to rotate the lead screw 522. After the lead screw 522 rotates, the sleeving block 523 is limited in the inside of the fixed frame 5115, so as to move downward along the outer wall of the lead screw 522, thereby moving the puncture needle 529 downward. After the puncture needle 529 moves downward, the abdominal cavity of the patient can be punctured, so as to improve the use effect of the device. The top of the lifting block 524 is fixedly connected with a U-shaped seat 5211, the inner wall of the U-shaped seat 5211 is in sliding connection with the outer wall of the rectangular block 5210, the outer wall of the lifting block 524 is fixedly connected with an L-shaped block 5212, the top of the L-shaped block 5212 is fixedly connected with a fixed block 5213, the inner wall of the fixed block 5213 is threadedly connected with a screw rod 5214, the outer wall of one end of the screw rod 5214 is fixedly connected with an adjusting block 5215, the other end of the screw rod 5214 is rotatably connected with a pressing block 5216, the outer wall of the pressing block 5216 is matched with the inner wall of the side of the rectangular block 5210, the side wall of the pressing block 5216 is fixedly connected with an L-shaped fixed plate 5217, the side wall of the L-shaped fixed plate 5217 is fixedly connected with a sliding rod 5218, the outer wall of the sliding rod 5218 is in sliding connection with the inner wall of the side of the fixed block 5213, when the puncture needle 529 is installed, in order to improve the stability of the puncture needle 529 in the puncture process, the puncture needle 529 needs to be fixed, at this time, the operator rotates the adjusting block 5215, so that the screw rod 5214 rotates, after the screw rod 5214 rotates, under the limiting of the sliding rod 5218 and the L-shaped fixed plate 5217 on the pressing block 5216, the pressing block 5216 moves, until the pressing blocks 5216 on the two sides are inserted into the inner walls of the two sides of the rectangular block 5210, so that the position of the rectangular block 5210 can be fixed, thereby improving the stability of the puncture needle 529 in the puncture operation of the abdominal cavity of the patient. The number of the pressing blocks 5216 is two, and the two pressing blocks 5216 are in sliding connection with the inner walls of the two sides of the rectangular block 5210.

[0021] A puncture method for a gastrointestinal surgical abdominal cavity operation, comprising the following steps: S1, first place the device above the abdominal cavity of the patient; S2, then start the servo motor 512, make the swing rod 514 swing along the inside of the semicircular frame 515, and then drive the fixed frame 5115 to move to the appropriate position during the swinging process; S3, then assemble the fixed ring 527, the positioning column 528, the puncture needle 529 and the lifting block 524; S4, then limit the rectangular block 5210 by the pressing block 5216, so as to fix the puncture needle 529; S5, finally, turn on the driving motor 521 to drive the lead screw 522 to rotate, drive the sleeve block 523 and the puncture needle 529 to lift, and realize the puncture operation of the abdominal cavity of the patient.

[0022] Working principle: when the patient's abdominal cavity is punctured before the operation, the operator first installs the device above the patient's abdominal cavity, and when the puncture position of the patient's abdominal cavity needs to be adjusted during the puncture operation, the operator starts the servo motor 512 to drive the output shaft 513 to rotate. During the rotation of the output shaft 513, the swing rod 514 will be rotated, and after the swing rod 514 is rotated, the connecting block 516 will be rotated, and during the rotation of the connecting block 516, the limiting block 5110 and the sliding block 5112 will be rotated at the center of the output shaft 513, so that the sliding block 5112 slides along the inside of the sliding groove 5111, and during the rotation of the limiting block 5110, the L-shaped connecting plate 5113 will also be rotated. During the rotation of the L-shaped connecting plate 5113, the other end of the second rotating rod 5114 connected to the inner wall of the side through the bearing is fixedly connected to the center of gravity of the fixed frame 5115, and when the L-shaped connecting plate 5113 is rotated, the fixed frame 5115 will be moved through the second rotating rod 5114, so as to adjust the displacement distance of the fixed frame 5115, thereby adjusting the puncture position of the patient's abdominal cavity. Because the counterweight 5116 is arranged at the bottom of the fixed frame 5115, the fixed frame 5115 can always be in a vertical state under the action of its own gravity during the movement of the fixed frame 5115, which can facilitate the operator to adjust the puncture position of the patient's abdominal cavity, and after the fixed frame 5115 is moved by the L-shaped connecting plate 5113, the puncture height of the patient's abdominal cavity can also be adjusted, thereby improving the use effect of the device; When the connecting block 516 rotates, the gear 518 will move, and during the movement of the gear 518, the first rotating rod 517 will rotate after meshing with the half-tooth ring 519. Through the meshing action of the gear 518 and the half-tooth ring 519, the position of the fixed frame 5115 after adjusting the puncture position can be limited, thereby improving the stability during the puncture process; When the puncture position of the patient's abdominal cavity is adjusted, the operator first inserts the puncture needle 529 into the inside of the through slot 525, so that the outer wall of the positioning column 528 is in close contact with the inner wall of the bearing ring 526. Then, by pressing the positioning column 528, the bottom of the fixed ring 527 is in close contact with the top of the bearing ring 526, so as to realize the installation of the puncture needle 529. After the installation of the puncture needle 529 is completed, the operator starts the driving motor 521 to drive the lead screw 522 to rotate. After the lead screw 522 rotates, the sleeve block 523 will move downward along the outer wall of the lead screw 522 under the limitation of the inside of the fixed frame 5115, thereby driving the puncture needle 529 to move downward. When the puncture needle 529 moves downward, the abdominal cavity of the patient can be punctured, thereby improving the use effect of the device; When the installation of the puncture needle 529 is completed, in order to improve the stability of the puncture needle 529 in the puncture process, the puncture needle 529 needs to be fixed, at this time, the operator rotates the adjusting block 5215 to drive the screw rod 5214 to rotate, after the screw rod 5214 rotates, under the limiting of the slide rod 5218 and the L-shaped fixing plate 5217 to the pressing block 5216, the pressing block 5216 is driven to move until the two pressing blocks 5216 are inserted into the two side inner walls of the rectangular block 5210, so that the position of the rectangular block 5210 can be fixed, thereby improving the stability of the puncture needle 529 in the puncture operation process of the abdominal cavity of the patient.

[0023] The above merely illustrates the specific embodiments of the present application, and is not intended to limit the scope of the present application. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present application shall fall within the scope of the present application. It should be noted that the components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be selected for single use or combined use according to actual needs, therefore, the present application naturally covers other combinations and specific applications related to the present application.
