[0003] 1. During pancreatic intestinal surgery, it is necessary to make an opening in the jejunum.

[0018] Beneficial effects of the present invention:

[0019] A pancreaticojejunostomy device of the present invention is provided with an expansion adsorption opening processing function. During pancreaticojejunal surgery, it is necessary to perform opening processing on the jejunal part. Since the space is narrow when performing surgery inside the abdominal cavity, the opening instruments in the prior art usually directly use a blade to cut an opening in a straight line on the surface of the jejunum, and then insert the two ends of the anastomosis supporter into the opening on the surface of the jejunum and the pancreatic duct to connect and complete the anastomosis. However, the straight opening cannot achieve complete aperture matching, which can easily lead to the problem of pancreatic fistula. At the same time, the pancreaticojejunostomy surgical instrument that can achieve opening processing When the device is used to make a hole on the surface of the jejunum, it is impossible to process the surface of the intestine, which leads to wrinkles on the surface and the inability to accurately determine the diameter of the hole, which will still cause pancreatic fistula problems in the later stage. When the present invention is used, after the port protection tube is close to the surface of the jejunal hole position, the electric telescopic rod is started to drive the transmission pull wire to gradually retract, so that the port protection tube slides backward relative to the adsorption treatment end tube, so that each group of adsorption-like spheres passes through the microporous adsorption port and approaches the surface of the jejunum, and when the vacuum pump body is started, the functional carrying shell is used to carry the adsorption spheres. The negative pressure retraction slot, the negative pressure channel, and the connected embedded tube are used for transmission, and a negative pressure adsorption effect is generated at the microporous adsorption port end, thereby adsorbing the surface of the jejunum. At the same time, the electromagnet is adjusted to start, driving the baffle to retract, so that the adjustable retraction slot is gradually connected, and the adsorption force is transmitted through the functional inner tube body, and a certain suction effect is generated on the central surface of the jejunum through the negative pressure center hole. In the process, it is further retracted through the port protective tube, and the damping transmission block drives the damping end block to slide, so that each group of adsorption spheres are deflected outward by being pulled by the linkage pull line, thereby adsorbing the air. The intestinal surface generates a pulling force outward to make the surface flat. Next, the transmission motor is started to drive the transmission outer tooth part to rotate through the transmission gear, so that the functional inner tube body rotates. The functional blade plate rotates together under the effect of the connection between the transmission mounting frame and the inner wall of the functional inner tube body. Therefore, under the effect of further angle deflection of the adsorption sphere and the hand pushing effect, the hole-making blade makes a hole on the flat surface of the target position, thereby avoiding the problem of pancreatic fistula caused by the wrinkles on the surface of the intestinal body in the prior art.

[0020] The expansion adsorption opening processing function of a pancreatico-enteric anastomosis device of the present invention can not only realize the adsorption and flattening processing of the intestinal surface, but also realize the recovery processing of the tissue after the opening. The negative pressure center hole generates a negative pressure adsorption effect in the center, which can realize the rapid flattening processing function of the intestinal surface in coordination with the expansion of the adsorption sphere. At the same time, during the cutting process and after the cutting is completed, the jejunal surface tissue is cut off by the opening blade, and under the effect of the backward sliding of the baffle, the adsorption force generated by the adjustable retraction slot gradually increases, that is, under the effect of the increased adsorption force at the center position of the negative pressure center hole, the cut intestinal tissue is retracted by the negative pressure center hole and placed in the functional inner tube body, so that after the cutting is completed, the cut tissue can be taken out by removing the through-slot baffle and placed in the storage box for storage, thereby avoiding the hidden dangers and efficiency problems of the prior art that the cut tissue cannot be recovered during the opening processing, which easily leads to the tissue being retained in the body or requiring additional steps for processing.

[0041] Specific use of the present invention:

The medical staff then holds the control body 11, extends the hole-punching mechanism 20 as a whole to the prepared hole-punching position of the jejunum, and places the port protection tube 43 close to the surface of the hole-punching position of the jejunum to perform a hole-punching operation.

[0043] A pancreaticojejunostomy device of the present invention is provided with an expansion adsorption opening processing function. During pancreaticojejunal surgery, it is necessary to perform opening processing on the jejunal part. Due to the narrow space when performing surgery inside the abdominal cavity, the opening instruments in the prior art usually directly use a blade to cut an opening in a straight line on the surface of the jejunum, and then insert the two ends of the anastomosis supporter into the opening on the surface of the jejunum and the pancreatic duct to connect and complete the anastomosis. However, the straight opening cannot achieve complete matching of the aperture, which can easily lead to the problem of pancreatic fistula. At the same time, the pancreaticojejunostomy surgical instrument that can achieve opening cannot achieve the problem of pancreatic fistula when opening the hole on the surface of the jejunum. The surface of the intestinal body is processed, and the wrinkles on the surface cause the diameter of the opening to be inaccurate, so there will still be a problem of pancreatic fistula in the later stage. When the present invention is used, after the port protection tube 43 is close to the surface of the jejunal opening position, the electric telescopic rod 95 is started to drive the transmission pull wire 36 to gradually retract, so that the port protection tube 43 slides backward relative to the adsorption treatment end tube 55, so that each group of adsorption spherical bodies 67 is close to the surface of the jejunum through the microporous adsorption port 69, and under the start of the back-evacuation vacuum pump body 16, the negative pressure back-evacuation notch 78 and the negative pressure channel 4 are passed through the functional carrying shell 19. 6. The inner tube 57 is connected for transmission, and a negative pressure adsorption effect is generated at the end of the microporous adsorption port 69, thereby adsorbing the surface of the jejunum. At the same time, the electromagnet 88 is adjusted to start, driving the baffle 83 to retract, so that the adjustable retraction slot 79 is gradually connected, and the adsorption force is transmitted through the functional inner tube body 45, and a certain suction effect is generated on the central surface of the jejunum through the negative pressure center hole 71. In the process, the port protection tube 43 is further retracted, and the damping transmission block 44 drives the damping end block 62 to slide, so that each group of adsorption spheres 67 are pulled outward by the linkage pull line 81, thereby adsorbing the surface of the jejunum. The surface is flattened by generating a pulling force outward, and the transmission motor 24 is started in the next step, and the transmission outer tooth portion 86 is driven to rotate through the transmission gear 25, so that the functional inner tube body 45 rotates, and the functional blade plate 70 rotates together under the effect of the connection between the transmission mounting frame 76 and the inner wall of the functional inner tube body 45, so that the hole-making blade 74 performs hole-making processing on the flat surface of the target position under the effect of further angle deflection of the adsorption-like sphere 67 and the hand pushing effect, thereby avoiding the problem of pancreatic fistula caused by the wrinkles on the surface of the intestinal body in the prior art, which leads to the inability to accurately make the hole diameter;

[0044] The expansion adsorption opening processing function of a pancreatico-enteric anastomosis device of the present invention can not only realize the adsorption and flattening processing of the intestinal surface, but also realize the recovery processing of the tissue after the opening. The negative pressure center hole 71 generates a negative pressure adsorption effect at the center, which can realize the rapid expansion of the adsorption sphere 67 to realize the flattening processing function of the intestinal surface. At the same time, during the cutting process and after the cutting is completed, the jejunal surface tissue is cut off by the opening blade 74, and under the effect of the backward sliding of the baffle 83, the adsorption force generated by the adjustable retraction slot 79 gradually increases, that is, under the effect of the increased adsorption force at the center position of the negative pressure center hole 71, the cut intestinal tissue is retracted by the negative pressure center hole 71 and placed in the functional inner tube 45. After the cutting is completed, the cut tissue is taken out by removing the through-slot baffle 92 and placed in the storage box 21 for storage, thereby avoiding the hidden dangers and efficiency problems of the prior art that the cut tissue cannot be recovered during the opening processing, which easily leads to its retention in the body or the need for additional steps for processing.
