Description

Technical Field

[0001] This invention relates to the field of positioning fixture technology, specifically a positioning device for stamping medical devices. Background Technology

[0002] Stamping equipment is frequently used in the remanufacturing of medical devices. Among them, the stapler is a medical device used to replace manual suturing. Its main working principle is to use titanium staples to cut or anastomose tissue, similar to a stapler. It consists of a handle body, a pusher, a staple cartridge seat, and an anvil seat. During the suturing operation, the distance between the anvil seat and the staple cartridge seat is adjusted according to the suture thickness.

[0003] The process of punching holes in the anvil is complicated. It requires manually snapping the anvil into the defined limiting groove before punching holes in the outer wall of the anvil. Since the stapler is used in the medical field, the workmanship requirements are very high. As a result, after punching the holes in the anvil, it will be embedded inside the fixed container, which is very troublesome to remove. Moreover, the anvils need to be placed and punched one by one, which is troublesome and wastes manpower.

[0004] Chinese Patent (Publication No. CN217550985U) discloses a positioning device for stamping medical instruments, including an interchangeable plate with a receiving cavity. Multiple vertical positioning components are located above the receiving cavity, and an anvil is installed inside the receiving cavity. Multiple mirror-image lateral ramps are located on both sides of the receiving cavity. A limiting groove is provided at one end of the receiving cavity, and a supporting surface is provided at the lower end of the receiving cavity. The vertical positioning components include two positioning bolts with a pressure block between them. The advantages of this invention are: the interchangeable plate, receiving cavity, and vertical positioning components work together to achieve rapid and accurate positioning. The limiting groove and supporting surface within the receiving cavity position the anvil at both ends and the lower end face, while the lateral ramps, positioning bolts, and pressure block position the upper end face of the anvil. The structure is simple, allows for quick clamping, and provides accurate and error-free positioning, ensuring the coaxiality of the anvil groove processing and improving production efficiency.

[0005] As can be seen from the above scheme, during use, the anvil needs to be placed inside the receiving cavity for fixing and limiting to complete the fixation. However, during use, since the anvil will be tightly embedded inside the receiving cavity after being stamped, it needs to be manually removed and fixed one group at a time, which wastes time and reduces the efficiency of manual work. In order to solve the problems of the anvil being tightly embedded inside the receiving cavity after being stamped and the time wasted in fixing the anvil one group at a time, we propose a positioning device for stamping processing of medical instruments.

[0011] As a further aspect of this solution, a connecting arm is fixedly connected to the upper end of the abutting block, and a second abutting wheel is rotatably connected to the outer wall of the connecting arm. A limiting cover with a reset function is rotatably installed on the upper end of the storage tube. A second abutting strip is fixedly connected to the inner wall of the mounting box, wherein the outer wall of one set of the second abutting wheels abuts against the second abutting strip. A first abutting strip is also fixedly connected to the inner wall of the mounting box. A discharge port is opened inside the first abutting strip, and the outer wall of the first abutting strip abuts against all the limiting covers.

[0012] As a further aspect of this solution, the rotating mechanism includes a fixed column, which is fixedly installed on the bottom of the inner wall of the mounting box. The upper end of the fixed column is rotatably connected to the rotating circular plate. A drive motor is fixedly installed inside the mounting box. A first gear is fixedly connected to the output end of the drive motor. A second gear is rotatably connected to the outer wall of the fixed column. The second gear meshes with the first gear. A mating tube is also rotatably connected to the outer wall of the fixed column. The bottom of the mating tube is fixedly connected to the second gear. A movable circular plate is rotatably connected to the outer wall of the fixed column. The bottom of the movable circular plate is rotatably connected to the mating tube. The upper end of the movable circular plate is fixedly connected to the rotating circular plate.

[0013] As a further aspect of this solution, the outer wall of the movable circular plate is provided with a locking interface, the outer wall of the mating tube is fixedly connected with a pulling arm, a pulling spring is also fixedly connected between the pulling arm and the movable circular plate, the outer wall of the movable circular plate is also rotatably connected with a fixed circular plate, and the fixed circular plate is fixedly connected to the inner wall of the mounting box. The bottom of the fixed circular plate is slidably connected with several locking blocks with a reset function, one set of locking blocks being locked in the inner wall of the locking interface.

[0014] As a further aspect of this solution, the limiting mechanism includes several limiting tubes, and the several limiting tubes are fixedly installed on the upper end of the rotating circular plate. The outer wall of the limiting tube has two sets of release ports, and the inner wall of the limiting tube is fixedly connected to a second elastic telescopic rod. The output end of the second elastic telescopic rod is rotatably connected to an abutment plate, and the outer wall of the abutment plate is also fixedly installed with a rubber pad. The limiting tube is fixedly connected to a limiting strip with a reset function.

[0015] As a further aspect of this solution, a connecting rod is fixedly connected to the upper end of the limiting strip, and a third abutting wheel is rotatably connected to the upper end of the connecting rod. An abutting ring is provided directly above the rotating circular plate, and the bottom of the abutting ring is fixedly connected to the inner wall of the mounting box. The outer wall of each set of the third abutting wheels abuts against the upper end of the abutting ring. The outer wall of the abutting ring is provided with a mating slope, and the outer wall of one set of the third abutting wheels abuts against the mating slope.

[0016] As a further aspect of this solution, a fixing ring is fixedly installed on the upper end of the rotating circular plate. The outer wall of the fixing ring has several openings, and each set of openings is adapted to the corresponding limiting tube.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When using this invention, the first elastic telescopic rod pushes the anvil into the limiting tube. The shape of the inside of the limiting tube and the inside of the storage tube can fit well with the outer wall of the anvil. The limiting strip limits the anvil in the inner wall of the limiting tube, making the anvil more firmly fixed and achieving the effect of precise positioning.

[0020] 3. When using this invention, after the punching of the anvil inside the limiting tube is completed, the anvil will be embedded in the inner wall of the limiting tube. This will prevent damage to the anvil when the worker disassembles it. When the third abutting wheel inside the limiting tube abuts with the matching ramp, the third abutting wheel pulls the connecting rod upward, the connecting rod drives the limiting clip to retract upward, and the second elastic telescopic rod pushes the anvil inside the limiting tube into the collection box, completing the unloading and collection of the anvil. It can also be used for rapid material collection without manual intervention. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 , 2 In this embodiment of the invention, a positioning device for stamping medical devices includes a mounting box 1. A cabinet door 3 is rotatably connected to the outer wall of the mounting box 1 via a rotating shaft. Both the mounting box 1 and the cabinet door 3 are fitted with glass covers, allowing workers to observe the interior of the mounting box 1 through the glass covers. A rotating mechanism 201 is fixedly installed at the bottom of the interior of the mounting box 1. A rotating circular plate 10 is also rotatably connected to the inner wall of the mounting box 1. The rotating mechanism 201 drives the rotating circular plate 10 to rotate. A limiting device for limiting and fixing the anti-pin seat is fixedly installed at the upper end of the rotating circular plate 10. The mounting box 1 also has a fixedly installed press 6 for stamping the anvil inside the limiting mechanism 301. The output end of the press 6 is fixedly installed with a stamping module 7, which is located above the rotating circular plate 10. The mounting box 1 also has a fixedly installed feeding mechanism 101 for feeding materials into the limiting mechanism 301. The mounting box 1 also has a fixedly installed display screen 8 for displaying data. The mounting box 1 also has a fixedly installed collection box 9 for collecting the anvil inside the limiting mechanism 301.

[0035] Example 2: Please refer to Figure 3 , 4As shown, the feeding mechanism 101 includes a movable plate 12, which is slidably mounted on the bottom of the mounting box 1. Specifically, two sets of sliding rods 11 are fixedly connected to the bottom of the mounting box 1, and the two sets of sliding rods 11 are symmetrically distributed on the bottom of the mounting box 1. The movable plate 12 is slidably mounted on the outer surface of the two sets of sliding rods 11. The outer wall of the sliding rods 11 is coated with lubricating oil. When the movable plate 12 slides on the outer wall of the sliding rods 11, the sliding rods 11 guide the movable plate 12, improving the stability of the movable plate 12 during movement. The lubricating oil reduces the friction between the movable plate 12 and the sliding rods 11, extending the service life of the movable plate 12 and the sliding rods 11. Two sets of tension springs 5 ​​are fixedly connected between the movable plate 12 and the inner wall of the mounting box 1. Furthermore, the two sets of tension springs 5 ​​are symmetrically distributed, and several storage tubes 16 are fixedly connected to the upper end of the moving plate 12. The storage tubes 16 are arranged in an array on the upper end of the moving plate 12. The cross-section of the storage tubes 16 is semi-circular, which can better fit with the anvil. The inner wall of the storage tubes 16 is fixedly connected to a first elastic telescopic rod 20 with a reset function. (It is worth noting that the first elastic telescopic rod 20 in the figure is in a squeezed state.) An abutment block is fixedly installed at the output end of the first elastic telescopic rod 20. The abutment block is also semi-circular. A rubber pad is fixedly installed on the outer wall of the abutment block. The rubber pad can effectively reduce the contact force with the anvil and reduce the squeezing force on the anvil. The end of the abutment block away from the first elastic telescopic rod 20 is rotatably connected to a first abutment wheel 14.

[0036] A connecting arm 19 is fixedly connected to the upper end of the abutment block. The connecting arm 19 is L-shaped. The outer wall of the connecting arm 19 is rotatably connected to a second abutment wheel 18 via a rotating shaft. A limit cover 21 with a reset function is rotatably installed on the upper end of the storage tube 16. A reset torsion spring is installed between the limit cover 21 and the storage tube 16. The limit cover 21 can prevent the pin seat inside the storage tube 16 from jumping out and limit the pin seat inside the storage tube 16. A second abutment strip 17 is fixedly connected to the inner wall of the mounting box 1. The second abutment strip 17 is parallel to all the limit covers 21 on the same horizontal plane. The outer wall of one set of second abutment wheels 18 abuts against the second abutment strip 17. A first abutment strip 15 is also fixedly connected to the inner wall of the mounting box 1. The first abutment strip 15 has an outlet 13 inside. The outer wall of the first abutment strip 15 abuts against all the limit covers 21. The outlet 13 is connected to the corresponding set of storage tubes 16.

[0037] Please see Figure 5 , 6As shown, the rotating mechanism 201 includes a fixed column, which is fixedly installed on the bottom of the inner wall of the mounting box 1. The upper end of the fixed column is rotatably connected to the rotating circular plate 10 via a rotating shaft. A drive motor 22 is fixedly installed inside the mounting box 1. A first gear 23 is fixedly connected to the output end of the drive motor 22. A second gear 29 is rotatably connected to the outer wall of the fixed column. The second gear 29 meshes with the first gear 23. A mating tube 2 is also rotatably connected to the outer wall of the fixed column. The bottom of the mating tube 2 is fixedly connected to the second gear 29. A movable circular plate 27 is rotatably connected to the outer wall of the fixed column. The bottom of the movable circular plate 27 is rotatably connected to the mating tube 2. The upper end of the movable circular plate 27 is fixedly connected to the rotating circular plate 10. A locking interface 30 is opened on the outer wall of the movable circular plate 2. A pulling arm 25 is fixedly connected to the outer wall of the mating tube 2. The end of the pulling arm 25 away from the mating tube 2 has a curved surface. A pulling spring 2 is also fixedly connected between the pulling arm 25 and the movable circular plate 27. 4. A fixed circular plate 26 is rotatably connected to the outer wall of the movable circular plate 27. The fixed circular plate 26 is located between the movable circular plate 27 and the rotating circular plate 10. A connecting column 41 is fixedly connected to the bottom of the fixed circular plate 26. The connecting column 41 is fixedly connected to the inner wall of the mounting box 1. Several locking blocks 28 with reset function are slidably connected to the bottom of the fixed circular plate 26. The locking blocks 28 are triangular. Each set of locking blocks 28 is adapted to the locking interface 30. One set of locking blocks 28 is locked in the inner wall of the locking interface 30. Specifically, several sliding frames are fixedly connected to the bottom of the fixed circular plate 26. Each set of locking blocks 28 is slidably connected in the inner wall of the corresponding sliding frame. An elastic spring is fixedly connected between the locking block 28 and the inner wall of the sliding frame. Since the outer wall of the pulling arm 25 has a curved surface, when the curved surface on the outer wall of the pulling arm 25 abuts against the locking block 28, the curved surface can greatly reduce the friction between the pulling arm 25 and each set of locking blocks 28.

[0038] Please see Figure 7 , 8As shown in Figure 9, the limiting mechanism 301 includes several limiting tubes 36, all of which are fixedly installed on the upper end of the rotating circular plate 10. The limiting tubes 36 are circumferentially distributed on the upper end of the rotating circular plate 10. Two sets of release ports 40 are provided on the outer wall of each limiting tube 36. A second elastic telescopic rod 35 is fixedly connected to the inner wall of each limiting tube 36. An abutment plate 34 is rotatably connected to the output end of the second elastic telescopic rod 35. A rubber pad is also fixedly installed on the outer wall of the abutment plate 34, serving the same function as the rubber pad on the outer wall of the abutment block, which will not be elaborated upon here. One set of limiting tubes 36 is interconnected with the corresponding storage tube 16. A limiting strip 38 with a reset function is fixedly connected inside each limiting tube 36. The limiting tube 36 has an installation cavity inside, and several return springs 37 are installed inside the installation cavity. The limiting strip 38 is slidably installed on the inner wall of the installation cavity. The end of the return spring 37 away from the installation cavity is fixedly connected to the limiting strip 38. When the anvil enters the limiting tube 36, it will first abut against the limiting strip 38. Since the cross-section of the limiting strip 38 is triangular, when the anvil and the limiting strip 38 abut against each other, the inclined surface of the limiting strip 38 can greatly reduce the friction between the limiting strip 38 and the anvil. When the anvil disengages from the limiting strip 38, the second elastic telescopic rod 35 will push the anvil to abut against the limiting strip 38 again, thus completing the limiting of the anvil.

[0039] A connecting rod 33 is fixedly connected to the upper end of the limiting clip 38. A third abutting wheel 31 is rotatably connected to the upper end of the connecting rod 33. An abutting ring 32 is provided directly above the rotating circular plate 10. The bottom of the abutting ring 32 is fixedly connected to the inner wall of the mounting box 1 (please refer to...). Figure 2 Each set of third abutting wheels 31 has its outer wall abutting against the upper end of the abutting ring 32. The outer wall of the abutting ring 32 is provided with a mating ramp 39. All the third abutting wheels 31 are adapted to the mating ramp 39, and the outer wall of one set of third abutting wheels 31 abuts against the mating ramp 39.

[0040] Please see Figure 7 As shown, a fixing ring 4 is fixedly installed on the upper end of the rotating circular plate 10. The outer wall of the fixing ring 4 has several openings, and each set of openings is adapted to the corresponding limiting tube 36.

[0041] The working principle of this invention is as follows: In use, it is only necessary to arrange the anvils inside each group of storage tubes 16 and use the first elastic telescopic rod 20 to abut the anvils. At this time, all anvils will be subjected to the squeezing force from the first elastic telescopic rod 20. The anvils will abut against the first abutting strip 15. The anvils inside the storage tube 16 connected to the discharge port 13 will be pushed into the corresponding limiting tube 36 by the first elastic telescopic rod 20. Since the inner wall of the limiting tube 36 and the storage tube 16 can fit well with the outer wall of the anvil, when the first abutting wheel 14 on the first elastic telescopic rod 20 pushes the anvil into the inner wall of the limiting tube 36, (based on the above) the anvil in the inner wall of the limiting tube 36 will be restricted by the limiting strip 38.

[0042] At this time, the drive motor 22 is started. The drive motor 22 drives the second gear 29 to rotate through the first gear 23. The second gear 29 drives the mating tube 2 and the pulling arm 25 to rotate together. Since the locking interface 30 inside the moving circular plate 27 is engaged with one of the locking blocks 28, the pulling spring 24 is stretched and the moving circular plate 27 is stationary. When the pulling arm 25 abuts against the locking block 28 inside the locking interface 30, the locking block 28 retracts, and the corresponding locking block 28 disengages from the locking interface 30. At this time, the pulling spring 24 returns to its deformation. In this process, it will pull the moving circular plate 27 to rotate. The locking interface 30 inside the moving circular plate 27 will engage with the next set of locking blocks 28. At the same time as the moving circular plate 27 rotates, it will also drive the rotating circular plate 10 to complete one rotation. The rotating circular plate 10 will drive the next set of limiting tubes 36 to connect with the discharge port 13. It is worth noting that when the limiting tube 36 moves, the next set of abutments inside the storage tube 16... Part of the pin seat will be located inside the corresponding limiting tube 36. At this time, the limiting tube 36 rotates, and the next set of pin seats will pass through the release port 40. At this time, the fixing ring 4 will abut against the pin seat, and the pin seat will enter the next set of limiting tubes 36 through the opening of the fixing ring 4. When no set of pin seats is lost inside the storage tube 16, the first elastic telescopic rod 20 will drive the second abutting wheel 18 to abut against the outer wall of the second abutting strip 17 through the abutting block. When the pin seats inside the storage tube 16 are used up, the first elastic telescopic rod 20 will drive the second abutting wheel 18 to abut against the outer wall of the second abutting strip 17 through the abutting block. Part of the first abutting wheel 14 will be located inside the corresponding limiting tube 36. At this time, since the second abutting wheel 18 disengages from the second abutting strip 17, the tension spring 5 will drive the first abutting wheel 14 to move through the moving plate 12. The first abutting wheel 14 will slide with the edge of the limiting tube 36 to reduce friction, and the next set of second abutting wheels 18 will continue to abut with the second abutting strip 17. The stamping module 7 will be driven by the stamping machine 6 to punch holes in the anvil inside the limiting tube 36.

[0043] When the third abutting wheel 31 inside the limiting tube 36 abuts against the mating ramp 39, the third abutting wheel 31 pulls the connecting rod 33 to move upward, the connecting rod 33 drives the limiting clip 38 to retract upward, and the second elastic telescopic rod 35 pushes the anvil inside the limiting tube 36 into the collection box 9, completing the unloading and collection of the anvil.

[0044] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
