Technical Field
[0001] The utility model relates to the technical field of medical devices, and particularly relates to a gastrointestinal anastomosis stent. Background Art
[0002] With the crazy expansion of tumors in patients, a large number of advanced patients are prone to lumen stenosis or inability to eat normally due to tumor ulceration, bringing great pain to the patients. Therefore, for patients, the stent is a very important need. By using a stent, his passage can be opened, allowing him to eat normally and complete his excretion, which is a great benefit to the patient.
[0003] Existing gastrointestinal anastomosis stents are usually designed as an integral structure. Although this structure is simple and easy to operate, in actual applications, there are some obvious deficiencies. Due to the lack of sufficient flexibility, it is difficult for doctors to make fine adjustments to the position and angle according to the specific conditions of the patients during the operation. Therefore, the utility model provides a gastrointestinal anastomosis stent to solve the problems raised in the above background art. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a gastrointestinal anastomosis stent, in which the anastomosis part and the conical part form a flared structure to adapt to the physiological structures of the stomach and intestine, ensure that the stent can closely fit the tissue during the anastomosis process, reduce the risk of leakage, and at the same time, the adjusting part located at one end of the stent tube and with an inclined structure enables it to adjust the angle when needed. And since the connection component adopts the clamping method of a buckle and a through groove, doctors can conveniently adjust the positions and angles of the connection section and the adjusting part to meet different surgical requirements.
[0005] To achieve the above purpose, a gastrointestinal anastomosis stent is provided, including a stent tube. A plurality of through grooves are opened inside the stent tube. A connection section is sleeved on one end of the stent tube. The side of the connection section away from the stent tube is connected with an anastomosis part through a conical part. The other end of the stent tube is rotatably connected with an adjusting part. The adjusting part is set as an inclined structure. Both the connection section and the adjusting part are clamped with adjacent through grooves through four equally spaced and symmetrically arranged connection components.
[0006] According to the described gastrointestinal anastomosis stent, the connection component includes a connecting piece and a buckle formed on the side of the connecting piece close to the stent tube. The buckle is clamped with the adjacent through groove.
[0007] According to the described gastrointestinal anastomosis stent, the anastomosis part and the conical part form a flared structure to adapt to the physiological structures of the stomach and intestine.
[0008] According to the described gastrointestinal anastomosis stent, the inner diameter of the adjusting part is the same as that of the stent tube.
[0009] According to the described gastrointestinal anastomosis stent, the surfaces of the stent tube, the conical part, the anastomosis part, and the adjustment part are all coated with biocompatible materials.
[0010] The utility model has the following beneficial effects:
[0011] Compared with the prior art, in this gastrointestinal anastomosis stent, the anastomosis part and the conical part form a flared structure to adapt to the physiological structures of the stomach and the intestine, ensuring that the stent can closely fit the tissue during the anastomosis process, reducing the risk of leakage. At the same time, the adjustment part located at one end of the stent tube and having an inclined structure enables it to adjust the angle when needed. Moreover, since the connection component adopts the clamping method of the buckle and the through groove, doctors can conveniently adjust the positions and angles of the connection section and the adjustment part to meet different surgical requirements.
[0012] The additional aspects and advantages of the utility model will be partially given in the following description, partially become apparent from the following description, or be understood through the practice of the utility model. Description of the Drawings

[0020] This part will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0021] Refer toFigures 1-4 , in an embodiment of the present utility model, a gastrointestinal anastomosis stent includes a stent tube 1. A plurality of through slots 6 are formed inside the stent tube 1. The through slots 6 not only contribute to the elastic deformation of the stent tube 1 but also provide a clamping position for the subsequent connection components. A connection section 2 is sleeved at one end of the stent tube 1. On the side of the connection section 2 away from the stent tube 1, an anastomosis section 4 is connected through a tapered section 3. The anastomosis section 4 and the tapered section 3 form a flared structure to adapt to the physiological structures of the stomach and intestine, ensuring that the stent can closely fit the tissue during the anastomosis process and reducing the risk of leakage. The other end of the stent tube 1 is rotatably connected to an adjustment section 7. To ensure that the internal channel remains unobstructed after the stent is fully deployed, the adjustment section 7 has the same inner diameter as the stent tube 1. The adjustment section 7 is provided with an inclined structure, and the inclined adjustment section 7 enables it to adjust the angle when needed to better adapt to different surgical requirements. Both the connection section 2 and the adjustment section 7 are clamped to the adjacent through slots 6 through four equally spaced and symmetrically arranged connection components. The connection component includes a connecting piece 5 and a buckle 8 formed on the side of the connecting piece 5 close to the stent tube 1. The buckle 8 is clamped to the adjacent through slot 6. Since the connection component adopts the clamping method of the buckle 8 and the through slot 6, doctors can conveniently adjust the positions and angles of the connection section 2 and the adjustment section 7 to adapt to different surgical requirements.
[0022] The surfaces of the stent tube 1, the tapered section 3, the anastomosis section 4, and the adjustment section 7 are all coated with a biocompatible material. The biocompatible material can be materials such as polylactic acid (PLA) to reduce the irritation and damage to the surrounding tissues and promote postoperative recovery.
[0023] Working principle: The anastomosis section 4 and the tapered section 3 form a flared structure to adapt to the physiological structures of the stomach and intestine, ensuring that the stent can closely fit the tissue during the anastomosis process and reducing the risk of leakage. At the same time, the adjustment section 7 located at one end of the stent tube 1 and having an inclined structure enables it to adjust the angle when needed. And since the connection component adopts the clamping method of the buckle 8 and the through slot 6, doctors can conveniently adjust the positions and angles of the connection section 2 and the adjustment section 7 to adapt to different surgical requirements.
[0024] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present utility model.
