[0002] Minimally invasive surgery is a current trend in surgical development, with laparoscopic and thoracoscopic surgeries increasingly applied across various medical fields. Minimally invasive surgery offers advantages such as less trauma, faster recovery, and reduced postoperative pain and complications. In esophagectomy followed by digestive tract reconstruction and anastomosis, the most common methods are gastric or jejunal esophageal replacement. Among reconstruction methods and alternative materials, gastric esophageal replacement is the most prevalent.

[0003] Stent anastomosis is a relatively new technique, and it has been applied to anastomosis of hollow organs, including the gastrointestinal tract, choledochoenterostomy, bile duct anastomosis, and vas deferens anastomosis. Combined with endoscopic ultrasound or X-ray guidance, a guidewire is used for puncture, and a balloon is inflated to release the stent to complete the anastomosis of the digestive tract. Endoscopic use provides a solution for anastomosis after gastrointestinal surgical resection. However, problems remain, such as stent dislodgement, difficulty in guidewire insertion, and surgical complexity. Utility Model Content

[0039] Based on the above, this utility model also has the following embodiments:

[0040] Furthermore, a minimally invasive anastomotic digestive tract stent visualization and release system further includes: a guidewire 5; one end of the guidewire 5 extends into the inner core 3 and is mounted on the puncture tip 10. Specifically, the guidewire 5 is used to guide the puncture tip 10 for tissue puncture.

[0041] Furthermore, a minimally invasive anastomotic digestive tract stent visualization release system is provided, wherein the conduit includes: an outer sheath 11 and an inner catheter 12; one outer wall of the inner catheter 12 is installed on one inner wall of the outer sheath 11, and the other outer wall of the inner catheter 12 has a gap with the other inner wall of the outer sheath 11, and the push conduit 2, inner core 3, puncture tip 10, and several balloons 9 are all located inside the inner catheter 12.

[0042] Furthermore, a minimally invasive anastomotic digestive tract stent visualization release system is provided, wherein a push plate 6 is provided at one end of the push tube 2, and one end of the inner core 3 extends out of the push tube 2 and the push plate 6 in sequence and is installed at the puncture tip 10. Specifically, the push plate 6 can adopt a disc or cylindrical structure, which can push several balloons 9 and stents 4 out of the inner catheter 12.

[0043] Furthermore, a minimally invasive anastomotic digestive tract stent visualization release system is provided, wherein the outer wall of the push plate 6 abuts against the inner wall of the inner catheter 12. Specifically, the contact between the outer wall of the push plate 6 and the inner wall of the inner catheter 12 improves the pushing effect on the balloon 9 and the stent 4, preventing them from being squeezed by the gap between the push plate 6 and the inner catheter 12.

[0044] Furthermore, a minimally invasive anastomotic digestive tract stent visualization and release system is provided, wherein a camera 7 is installed at one end of the gap near the puncture tip 10. Specifically, the camera 7 is a camera with a light source, used to observe the delivery and release process of the stent 4.

[0045] Furthermore, a minimally invasive anastomotic digestive tract stent visualization release system further includes: a traction wire 8; the traction wire 8 extends into the inner catheter 12 and passes through the push plate 6 to be installed on the stent 4. Specifically, when observing the placement of the stent 4 through the camera 7, if the stent 4 still needs slight adjustment, it can be adjusted using the traction wire 8.

[0046] Furthermore, a minimally invasive anastomotic digestive tract stent visualization release system includes a push plate 6 with several through holes. An inner core 3 passes through one through hole and is installed at the puncture head end 10. Several inflation tubes pass through the corresponding through holes and are connected to a balloon 9. A traction wire 8 passes through one through hole and is installed at the stent 4. Specifically, the through holes on the push plate 6 not only have an air venting function but also allow the inner core 3, inflation tubes, and traction wire 8 to pass through and be installed at the puncture head end 10, balloon 9, and stent 4.

[0047] Furthermore, a minimally invasive anastomotic digestive tract stent visualization and release system is provided, wherein the end of the guidewire 5 installed at the puncture tip 10 is the puncture end, which is a rigid end, and the end of the guidewire 5 extending out of the inner core 3 is the operating end, which is a flexible end.

[0048] Furthermore, a minimally invasive anastomotic digestive tract stent visualization and deployment system further includes a control device connected to a camera 7. Specifically, the signal from the camera 7 is transmitted to the control device, which then observes the placement of the stent 4.

[0049] In a preferred embodiment, the device further includes a negative pressure aspirator located between the inner catheter 12 and the push catheter 2. The negative pressure aspirator can connect to the position of the puncture tip 10 through the through hole of the push plate 6, allowing the negative pressure aspirator to expel air from the position of the puncture tip 10 and aspirate the puncture tip tissue, such as... Figure 6 As shown, this facilitates the puncture of the guidewire 5, and can also be connected to an inflatable device via a negative pressure suction device to dilate the esophagus at the tip, making it easier for the camera 7 to see the tissue in front.

[0050] In practical use, this application has the following steps:

[0051] Step 1: Please refer to the following for details. Figures 5 to 6 As shown, the inner core 3 is pushed downward relative to the tube 1. At this time, the inner core 3 drives the pushing tube 2 to also be pushed downward relative to the tube 1. The pushing tube 2 pushes the balloon 9 to move downward as well. During this process, the tissue puncture site can be aspirated by the negative pressure suction device, so that the tissue puncture site is as... Figure 6 The center is concave, which facilitates better tissue puncture;

[0052] Step Two: Please refer to the details below. Figures 7 to 8 As shown, the inner core 3 drives the puncture tip 10 to perform tissue puncture;

[0053] Step 3: Please refer to the details below. Figure 9 As shown, the inner core 3 drives the puncture head 10 to continue moving downward until the stent 4 is in the designated position. Several balloons 9 are inflated through the inflation tube. The balloons 9 expand to assist or promote the expansion and fixation of the stent 4 in the digestive tract. During the fixation process of the stent 4, the stent delivery and release process can be observed through the camera 7. If the position of the stent 4 is not suitable, it can be slightly adjusted.

[0054] Step 4: Please refer to the following for details. Figure 10 As shown, after the stent 4 is fixed, the gas in several balloons 9 is discharged through the inflation tube, and the puncture tip 10 is brought out of the digestive tract through the inner core 3.

[0055] Step 5: Please refer to the following for details. Figure 11 As shown, the inner core 3 is finally pulled upward relative to the channel, and the inner core 3 drives the puncture tip 10 to withdraw from the tissue puncture site, so that the balloon 9 and the puncture tip 10 return to the channel 1.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model.
