Description

Technical Field

[0001] The utility model relates to an in vitro magnetic force guided puncture device with a plannable path. Background Art

[0002] When inflammation, bleeding, leakage, and other diseases occur in the organs or tissues of the thoracic and abdominal cavities, it is necessary to drain the inflammatory exudate, blood, and leaked body fluids (such as intestinal fluid, bile, pancreatic fluid, etc.) out of the body in a timely manner, because these fluids may contain some digestive substances such as pancreatic lipase and bile, which can directly erode the surrounding tissues. For example, after the pancreas leaks, pancreatic enzymes can corrode the surrounding blood vessels, causing the patient to bleed to death. At the same time, there may also be a large number of bacteria in the leaked fluid, leading to infection in the body cavity, cell necrosis, and pus. The absorption of a large amount of purulent substances may cause septic shock in the patient.

[0003] At present, the drainage tube is usually inserted into the patient's body wall after incision. However, it is difficult to directly insert the drainage tube into some special parts such as the retroperitoneum through traditional methods. This is because the retroperitoneal space is located deep in the abdominal cavity, covered by the intestines, mesentery, liver, etc. in front, and covered by tough muscles such as the iliopsoas muscle in the back. Therefore, it is usually difficult to reach the appropriate position when puncturing the retroperitoneal space, and it is easy to damage the surrounding trachea. For example, when puncturing patients with pancreatic abscesses, in order to reach the appropriate position and minimize damage to the intestines, it is usually necessary to directly puncture the liver, pass through the liver parenchyma, and then reach the back of the pancreas. However, this method causes great damage to the liver and is likely to cause heavy bleeding in patients. In addition, the diameter of the drainage tube is limited, and it cannot pass through a thicker drainage tube, which limits the drainage effect. Utility Model Content

[0004] The utility model aims to provide an extracorporeal magnetic-guided puncture device with a plannable path, so as to solve the technical problem that the existing puncture for abdominal abscess is inconvenient for flushing and drainage.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The present invention is further described in detail below in conjunction with the embodiments.

[0023] like Figure 1-6 As shown, a specific embodiment 1 of an extracorporeal magnetic force guided puncture device with a plannable path provided by the utility model is:

[0024] An extracorporeal magnetic force guided puncture device with a plannable path comprises a magnetic adhesive tape, an outer covering tape, an inner sleeve 1, a drainage tube 2 and an endoscope 3;

[0025] The magnetic adhesive tape comprises a plurality of adhesive stickers 4, each adhesive sticker 4 has a built-in magnet 5, and all the adhesive stickers 4 are connected by a plurality of connecting ropes 6;

[0026] The outer covering belt 7 includes a sponge layer 8, the outer surface of the sponge layer 8 is provided with a waterproof layer 9, the back of the outer covering belt 7 is provided with an adhesive ring 10, the two ends of the outer covering belt 7 are provided with extension parts 11, and the ends of the two extension parts 11 are correspondingly provided with snap structures 12; the edge of the outer covering belt 7 is connected to two hanging rings 13, and the hanging rings 13 are used to hang the drainage bag.

[0027] The outer wall of the drainage tube 2 is provided with a plurality of magnetic rings 14, all of which are arranged at intervals. A water injection joint 15 is connected to the side wall of the lower end of the drainage tube 2. The lower end of the drainage tube 2 is provided with an external sleeve 16, which has an internal thread.

[0028] An inner sleeve 17 is disposed at the lower end of the inner sleeve 1 . The inner sleeve 17 is provided with an outer thread matched with the inner thread of the outer sleeve 16 . A suction tube 18 is connected to the lower end of the inner sleeve 17 .

[0029] Before puncture, firstly, a suitable puncture point is planned according to the patient's preoperative examination (such as CT, MRI), and then a puncture route is planned according to the puncture point and the intended location. Then, the magnetic adhesive tape is pasted on the puncture route, and when pasting, it is ensured that the closer to the intended location in the body, the denser the distribution of the adhesive tape 4 is, and the farther away from the puncture point, the sparser the distribution of the adhesive tape 4 is. Then, the puncture needle is used to pierce the body wall, and the drainage tube 2 is introduced into the body cavity from the puncture site. Since a plurality of magnetic rings 14 are arranged at intervals on the outer wall of the drainage tube 2, after the drainage tube 2 enters the body, it moves along the distribution route of the magnet 5 outside the body wall under the attraction of the magnet 5. After a magnetic ring 14 is attracted by the magnet 5 outside the body, it continues to push the drainage tube 2 forward. The rear magnetic ring 14 and the magnet 5 continue to attract each other alternately. When the puncture is just started, an endoscope 3 is inserted into the drainage tube 2 to facilitate observation of the position in the body cavity during the pushing process, and then adjust the direction. After reaching the intended drainage site, the endoscope 3 is withdrawn, the inner sleeve 1 is inserted, and then the inner sleeve 17 is threadedly installed on the outer sleeve 16; finally, the outer covering tape 7 is covered on the outside of the magnetic adhesive tape, and after being wrapped around for one week, it is fixed by the buckle structure 12. When the drainage tube 2 needs to be pulled out, the outer covering tape 7 and the magnetic adhesive tape are removed, and the drainage tube 2 can be pulled out.
