Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a pancreatic-jejunal anastomosis surgical forceps. Background Art

[0002] Pancreatic-jejunal anastomosis is a surgical operation for treating pancreatic diseases or pancreatic cancer. In this operation, a part of the pancreas is connected to the small intestine so that pancreatic secretions can be smoothly discharged out of the body. Pancreatic-jejunal anastomosis surgery is usually divided into two types: pancreatoduodenal anastomosis and pancreatic-jejunal anastomosis. Pancreatoduodenal anastomosis is to connect the head of the pancreas to the duodenum, while pancreatic-jejunal anastomosis is to connect the tail of the pancreas to the jejunum.

[0003] The operation of pancreatoduodenal anastomosis is as Figure 1 shown. First, the pancreas is transected, and the edge of the head end of the pancreas is sutured to the edge of the intestinal wound. If a conventional surgical forceps is used to clamp the pancreas for operation, there will be many problems: firstly, the jaws of the conventional surgical forceps are two straight arms, which are difficult to clamp the pancreas tightly, and the clamping force is not easy to control, which is easy to damage the pancreas; secondly, when suturing, the adjacent suture needle intervals are not easy to accurately control, and it is easy to have uneven suture needle paths, reducing the suture quality and also increasing the technical requirements for doctors. Content of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide a pancreatic-jejunal anastomosis surgical forceps, aiming to solve the above technical problems.

[0005] The utility model adopts the following technical scheme:

[0006] The pancreatic-jejunal anastomosis surgical forceps includes two forceps arms hinged together. The front part of the forceps arm at the hinge point is the clamping part, and the rear part is the handheld part. The clamping part is an outwardly convex arc, and a row of needle insertion grooves are evenly opened on the side of the clamping part. A limiting mechanism is arranged on the inner sides of the tails of the two clamping parts.

[0007] Further, the needle insertion groove includes a shallow groove perpendicular to the clamping part, and the outer side of the shallow groove is a flared guiding port.

[0008] Further, the edge of the guiding port is chamfered.

[0009] Further, the two handheld parts are respectively the first handheld part and the second handheld part. The limiting mechanism includes a first tooth block integrally formed with the first handheld part and a second tooth block slidably and fixedly installed on the second handheld part. The two tooth blocks are staggered and arranged with their tooth surfaces facing each other.

[0010] Further, a short groove is opened on the inner side of the second handheld part. The rear part of the second tooth block is located in the short groove and is provided with a strip-shaped hole, and the strip-shaped hole is screwed with a screw to be locked to the short groove.

[0011] The beneficial effects of the present utility model are as follows: This surgical forceps is applicable to pancreatic-jejunal anastomosis surgery. When using the surgical forceps to clamp the neck of the pancreas near the head end, since the clamping part of the surgical forceps is arc-shaped, the pancreatic neck is clamped between the arc-shaped clamping parts. On the premise of ensuring convenient clamping operation, the pressure of the clamping part on the pancreas is reduced, avoiding damage to the pancreas. On the other hand, a row of needle insertion grooves is evenly arranged on the clamping part. When suturing, the needle is inserted through the needle insertion groove, penetrates through the edge of the pancreas and then continues to penetrate through the edge of the intestinal wound and exits, and knots can be tied. Then continue to repeat the operation. Each time the needle is inserted and guided through the needle insertion groove, the needle insertion spacing is ensured and the operation is simpler.

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] In order to illustrate the technical solutions described in the present utility model, the following will be illustrated through specific embodiments.

[0019] As Figure 2-5 shown, the pancreatic-jejunal anastomosis surgical forceps provided by this embodiment includes two hinged forceps arms. The front part of the forceps arm at the hinge point is the clamping part 1, and the rear part is the handheld part 2. The clamping part 1 is an outwardly convex arc, and a row of needle insertion grooves 3 are evenly opened on the side of the clamping part 1. A limiting mechanism 4 is arranged on the inner sides of the tails of the two clamping parts 2.

[0020] The structural design of this surgical forceps has three characteristics. First, the clamping part of the surgical forceps is arc-shaped, and the neck of the pancreas is clamped between the arc-shaped clamping parts. Compared with the surgical forceps with straight arms, the clamping operation is simpler. Moreover, on the premise of ensuring convenient clamping operation, the compression force of the clamping part on the pancreas is reduced, avoiding damage to the pancreas. Second, a row of needle insertion grooves is evenly arranged on the clamping part. When suturing, the needle is inserted through the needle insertion groove until it successively penetrates the edge of the pancreas and the edge of the intestinal wound, and then knotting can be performed. Then continue to repeat the operation, and each time the needle is guided through the needle insertion groove, ensuring the needle insertion spacing and making the operation simpler. Third, the limiting mechanism at the tail of the clamping part can prevent the jaws of the surgical forceps from accidentally loosening after clamping the pancreas.

[0021] When using this surgical forceps, first insert the surgical forceps to clamp the neck or body of the pancreas, then transect the neck of the pancreas, bring the head end of the pancreas close to the wound of the intestine, and then insert the suture needle through the needle insertion groove in the above-mentioned manner. After piercing the edge of the pancreas, continue to insert it into and out of the edge of the intestinal wound, and then perform knotting, repeating this operation. Each time the needle is guided through one needle insertion groove, ensuring the needle insertion spacing and making the operation simpler.

[0022] To facilitate the insertion of the suture needle into the needle insertion groove, as a specific structure, the needle insertion groove 3 includes a shallow groove 31 perpendicular to the clamping part 1, and the outside of the shallow groove 31 is a flared guiding port 32. The edge of the guiding port 32 is chamfered to reduce sharp edges. Due to the setting of the flared guiding port, as long as the tip of the suture needle is located within the guiding port, it can smoothly penetrate out of the shallow groove, reducing the operation difficulty.

[0023] In addition, for the convenience of description, the two holding parts 2 are respectively denoted as the first holding part 21 and the second holding part 22. In this structure, the limiting mechanism 4 includes a first tooth block 41 integrally formed with the first holding part 21, and a second tooth block 42 slidably and fixedly installed with the second holding part 22. The two tooth blocks are staggered and the tooth surfaces are arranged opposite to each other. After the surgical forceps are clamped, the two tooth blocks are staggered and engaged, and the jaws of the surgical forceps will not easily loosen, preventing the pancreas from slipping. At the same time, the position of the second tooth block is adjustable. Specifically, a short groove 23 is opened on the inner side of the second holding part 22, the rear part of the second tooth block 42 is located in the short groove 23 and a strip hole 43 is opened, and the strip hole 43 is screwed with a screw 44 and locked to the short groove 23. Considering the different sizes of the pancreas, during normal operation, it is directly clamped to make the jaws close, and the two tooth blocks are basically completely overlapped. At this time, the clamping force is sufficient and the pancreas will not be damaged. For a larger pancreas, the position of the second tooth block can be adjusted outwards. Before the jaws close, the second tooth block has already abutted against the first holding part, so that the closing degree of the surgical forceps can be controlled, and then the clamping force on the pancreas can be adjusted. Therefore, this surgical forceps can adapt to pancreases of different sizes.

[0024] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
