Description

Technical Field

[0001] The present invention relates to the technical field of stapler manufacturing, and specifically to a stapler staple inserting device and method. Background Art

[0002] A stapler is a medical device used to quickly connect human tissues during surgical operations, mainly used to replace traditional manual suturing, improving surgical efficiency and safety; simply put, it is like a "medical stapler", which re-closes severed tissues such as blood vessels, intestines, and skin through metal staples or suture materials; in surgeries such as gastrointestinal resection, vascular anastomosis, or organ transplantation, doctors can complete complex suturing within a few minutes using a stapler, reducing the risk of bleeding and infection for patients; compared with traditional suturing, this device operates more precisely, especially suitable for minimally invasive surgical scenarios such as laparoscopy, helping doctors complete delicate operations in a narrow space.

[0003] Staplers include circular staplers and linear staplers, which are respectively equipped with circular staple cartridges and linear staple cartridges; the circular staple cartridge contains several staple groove circles, and each staple groove circle includes multiple staple grooves for inserting staples; the linear staple cartridge contains several staple groove rows, and each staple groove row includes multiple staple grooves for inserting staples; the staple cartridge is a disposable product, which is loaded with staples in the factory, sent to the hospital for doctors to use after being loaded, and discarded after use; the difficulty in manufacturing the staple cartridge lies in loading the staples; the method of loading staples is for people to use clips or for machines to use manipulators to clamp the legs of the staples and insert them into the staple cartridge; for example, the staple loading system for a stapler with the publication number CN209954132U and a staple loading device for a stapler staple cartridge with the publication number CN118161214A both use machines with manipulators to clamp the legs of the staples and insert them into the staple cartridge.

[0004] The difficulty in loading staples into the staple cartridge lies in that the staple grooves in the cartridge for inserting staples are very small, there are a large number of them, and the fit between the staple grooves and the staples is relatively tight, with very high requirements for the fineness of the operation; a deviation in the insertion angle during staple insertion will cause the staples to deform; and when inserting staples, it is necessary to clamp the legs and insert them into the staple grooves, and it is very easy for uneven stress on both sides of the staples to occur, resulting in staple deformation.

[0005] The disadvantages of using manual staple insertion are low efficiency; the disadvantages of the method of using a manipulator to clamp the legs of the staples and insert them into the staple cartridge are that the position of each staple insertion by the manipulator is different, with very high requirements for the positioning accuracy of the manipulator, resulting in high manufacturing and maintenance costs of the manipulator; and the tolerance rate is low, and errors will occur after being used for a period of time, making debugging difficult. Summary of the Invention

5. The stapling device of the stapler according to claim 1, wherein A positioning groove (101a) for positioning the anastomotic staple (6) is fixedly connected to the top of the inserting plate (101).

6. The stapling device of the stapler according to claim 1, characterized in that, It further includes a vibrating disk for arranging the staples (6) in an orderly manner and a conveying track for conveying the staples (6) from the vibrating disk to the staple dropping device (2).

7. A stapling method of a stapler, characterized in that, Using the staple inserting device in Claim 2, it includes the following steps: S1. In the initial state, one of the staple inserting locators (1) on the chassis (3) is located directly below the staple dropping device (2), the staple cartridge (5) is located directly above the staple inserting locator (1), and the inserting plate (101) is facing the staple groove (501) in the staple cartridge; S2. Send the staple (6) to the staple dropping device (2) so that the legs of the staple (6) face downwards and are stuck on the staple base plate (201); S3. The push plate (202) pushes the staple (6) so that the staple (6) falls between the first limiting plate (102) and the second limiting plate (103) and slides downwards to the top of one of the inserting plates (101). The legs of the staple face downwards and are stuck on the top of the inserting plate (101); S4. Repeat step S2 once, and at the same time, the chassis (3) rotates by a certain angle so that the next staple inserting locator (1) rotates to directly below the staple dropping device (2), and repeat step S3; S5. Repeat step S4 multiple times until all the inserting plates (101) on the chassis (3) are clamped with staples (6); S6. The staple dropping device (2) moves backward, the staple cartridge (5) moves downward, and the inserting plate (101) inserts the staple (6) into the staple groove (501); during the process of the inserting plate (101) inserting into the staple groove (501), the first limiting plate (102) and the second limiting plate (103) move downward and compress the elastic device (104); S7. The staple cartridge (5) moves upward, and the staple (6) remains in the staple groove (501); under the action of the elastic device (104), the first limiting plate (102) and the second limiting plate (103) reset upward.

8. A stapling method of a stapler, characterized in that, Using the staple inserting device in Claim 4, it includes the following steps: S1. In the initial state, one staple inserting locator (1) on each of the two locator rows of each bottom block (4) is located directly below the staple dropping device (2), and the staple cartridge (5) is located above the staple inserting locator (1); S2. Send the staple (6) to the staple dropping device (2) so that the legs of the staple (6) face downwards and are stuck on the staple base plate (201); S3. The push plate (202) pushes the staple (6) so that the staple (6) falls between the first limiting plate (102) and the second limiting plate (103) and slides downwards to the top of the inserting plate (101). The legs of the staple face downwards and are stuck on the top of the inserting plate (101); S4. Repeat step S2 once, and at the same time, the bottom block (4) moves a certain distance so that the other two staple inserting locators (1) move to directly below the staple dropping device (2), and repeat step S3; S5. Repeat step S4 multiple times until all the inserting plates (101) on the bottom block (4) are clamped with staples (6), and the inserting plate (101) on one of the bottom blocks (4) is facing the staple groove (501) in the staple cartridge (5); S6. The nail driver (2) moves backward and the nail magazine (5) moves downward. The inserting plate (101) on one of the bottom blocks (4) inserts the anastomosis nails (6) into the nail grooves (501). When the inserting plate (101) inserts into the nail groove (501), the first limiting plate (102) and the second limiting plate (103) move downward and compress the elastic device (104). S7. The nail magazine (5) moves upward and the anastomosis nails (6) remain in the nail grooves (501). Under the action of the elastic device (104), the first limiting plate (102) and the second limiting plate (103) reset upward. S8. Move the position of the bottom block (4), and the inserting plates (101) on the other bottom blocks (4) also insert the anastomosis nails (6) into the nail grooves (501) until all the nail grooves (501) are inserted with anastomosis nails (6).
