Description
Technical Field
The utility model relates to a medical supplies technical field, concretely relates to cascaded pancreas support of absorbing.
Background
Pancreatoduodenectomy, also known as Whipple surgery (Whipple surgery), is an operative treatment for common bile duct middle and lower segment cancer, around ampulla of vater, duodenal malignant tumor, early pancreatic head cancer, severe pancreas and duodenal trauma, and other diseases. Pancreas duodenectomy has a large risk of operation and a high complication rate because of the removal of many organs and a plurality of anastomotic stoma (including pancreas enteroanastomosis, cholangioenteroanastomosis and gastrointestinal anastomosis). Among them, pancreatic leakage is a serious complication, even leading to massive intra-abdominal bleeding and death of the patient.
In response to the complication of pancreatic leakage, surgeons have performed numerous improvements in the manner of pancreaticostomy. However, the existing stent is too complicated, and an absorbable pancreatic duct stent used in the operation is not available, so that the application value in the operation is not high. Therefore, the manufacturing of the absorbable pancreatic duct stent has great significance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a cascaded pancreas support of absorbing, it can solve the problem that exists among the background art effectively.
In order to solve the problems in the background art, the step-type absorbable pancreatic duct bracket is a bracket consisting of a first bracket tube 1, a second bracket tube 2 and a third bracket tube 3, and the whole bracket is of a hollow tubular structure;
the outer diameter of the first support pipe 1 is 2mm, the inner diameter of the first support pipe is 1.5mm, and the length of the first support pipe is 2 cm;
the outer diameter of the second support pipe 2 is 3mm, the inner diameter of the second support pipe is 2.5mm, and the length of the second support pipe is 2 cm;
the outer diameter of the third support tube 3 is 4mm, the inner diameter is 3.5mm, and the length is 2 cm;
a first inclined plane is arranged between the first support pipe 1 and the second support pipe 2, and the length of the first inclined plane is 4 mm;
a second inclined plane is arranged between the second support pipe 2 and the third support pipe 3, and the length of the second inclined plane is 4 mm;
the whole bracket is manufactured by processing 3D printing equipment;
the stent is made of polylactic acid which is a bioabsorbable material.
The first inclined plane and the second inclined plane are respectively provided with a grid pattern, so that the separation in the operation is facilitated.
Owing to adopted above technical scheme, the utility model discloses following beneficial effect has: the bracket has simple structure, is made of absorbable materials, and has great application value in the operation.
Drawings
In order to more clearly illustrate the present invention, the following description will briefly describe embodiments with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, creation features, achievement purpose and efficacy of the present invention easy to understand, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical solution in the embodiments of the present invention.
Referring to fig. 1, the present embodiment is realized by adopting the following technical scheme that a step-type absorbable pancreatic duct stent is a stent formed by a first stent tube 1, a second stent tube 2 and a third stent tube 3, and the stent is of a hollow tubular structure as a whole;
the outer diameter of the first support pipe 1 is 2mm, the inner diameter of the first support pipe is 1.5mm, and the length of the first support pipe is 2 cm;
the outer diameter of the second support pipe 2 is 3mm, the inner diameter of the second support pipe is 2.5mm, and the length of the second support pipe is 2 cm;
the outer diameter of the third support tube 3 is 4mm, the inner diameter is 3.5mm, and the length is 2 cm;
a first inclined plane is arranged between the first support pipe 1 and the second support pipe 2, and the length of the first inclined plane is 4 mm;
a second inclined plane is arranged between the second support pipe 2 and the third support pipe 3, and the length of the second inclined plane is 4 mm;
the whole bracket is manufactured by processing 3D printing equipment;
the stent is made of polylactic acid which is a bioabsorbable material.
The principle of the technical scheme in the embodiment is further explained with the accompanying drawings as follows:
the diameter of the pancreatic duct can be selected from a proper section during operation, the joint is designed to be in a grid shape, so that the selection is convenient, and the formation of postoperative pancreatic duct calculus is reduced.
The bracket tube is tied by an absorbable suture and then is fixed at the position of a pancreas and intestine anastomosis, so that the bracket tube has a supporting effect on anastomotic leakage. The stent tube is absorbed after the anastomotic healing.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
