Abstract
Description
Technical Field
[0001] This application relates to the field of staple removal device technology, and in particular to a staple removal device for staple assembly. Background Technology
[0002] In modern surgery, staplers are widely used for tissue cutting and suturing. Staplers achieve suturing by inserting pre-loaded staples into the tissue. However, traditional staples must be manually assembled into the staple cartridge, which is not only inefficient but also prone to problems such as staple misalignment and dislodgement.
[0003] To improve the assembly efficiency of staples, an automated staple removal device is commonly used. This device includes a base, a negative pressure suction block, and a moving block. The moving block is movably connected to the base, and the negative pressure suction block is located on the moving block. The negative pressure suction block uses negative pressure to attract the staples, and the staples are installed as the moving block moves. However, in actual use, although the staple removal device improves the efficiency of staple removal, displacement deviations between the staples and the staple cartridge still occur when transferring the staples into the cartridge, or external factors, such as natural wind, can cause misalignment of the staples during installation. Utility Model Content
[0004] To address the issue of potential displacement deviations during staple installation, which could lead to misalignment, this application provides a staple removal device for staple assembly.
[0005] The staple removal device for staple assembly provided in this application adopts the following technical solution:
[0006] A staple removal device for staple assembly includes a frame, a moving component, a staple removal component, and a limiting component. The frame is provided with a feeding mechanism and a staple magazine. The feeding mechanism is used to convey staples to a removal position. The staple magazine is located at a position corresponding to the feeding mechanism. The moving component includes a moving block and a driving component. The driving component drives the moving block to reciprocate between the feeding mechanism and the staple magazine. The staple removal component includes a staple removal block and a negative pressure mechanism. The staple removal block is connected to the negative pressure mechanism and is located on the moving block. The staple removal block has a plurality of staple removal holes. The limiting component is located inside the staple removal block and is used to limit the position of the staple after it is separated from the staple removal block.
[0007] By adopting the above technical solution, the moving block drives the nail-removing block to pick up and move the nail. When the nail-removing block moves to the position corresponding to the nail cartridge, the limiting component cooperates with the nail-removing block to limit the position of the staple to be assembled. Then the negative pressure mechanism stops running, and the staple falls into the staple cartridge under the action of gravity. With the cooperation of the limiting component, not only is the nail-removing efficiency improved, but the consistency of the relative position between the staple and the staple cartridge can also be ensured, reducing the probability of misalignment when the staple is installed.
[0008] Preferably, the limiting component includes a limiting cylinder and a limiting plate. The limiting cylinder is disposed inside the nail-removing block, and the limiting plate is connected to the piston rod of the limiting cylinder. The limiting plate is slidably connected to the nail-removing block, and the limiting plate is used to limit the staple on both sides.
[0009] By adopting the above technical solution, before the staples are dropped, the limiting cylinder drives the limiting plate to extend the staple block and limits the staples on both sides.
[0010] Preferably, the limiting assembly further includes a limiting rod and a limiting connecting rod. The limiting rod is slidably connected to the nail-removing block. The limiting rod and the limiting plate are connected by the limiting connecting rod. The limiting rod is used to limit the staple at both ends.
[0011] By adopting the above technical solution, when the limiting cylinder drives the limiting plate to extend and move, the limiting rod extends synchronously through the driving of the limiting linkage. The limiting rod can limit the two ends of the staple and cooperate with the limiting plate to limit the overall position of the staple.
[0012] Preferably, the nail-removing assembly further includes a push plate and a push cylinder for driving the push plate to move. The push cylinder is disposed inside the nail-removing block, and the push plate is connected to the end of the piston rod of the push cylinder. When the nail-removing block removes a nail, the matching nail is in contact with the push plate.
[0013] By adopting the above technical solution, when the staples move to the position corresponding to the staple cartridge, the cylinder is activated to drive the push plate to move, and the push plate drives the staples to move toward the staple cartridge.
[0014] Preferably, the push plate has a plurality of adsorption holes.
[0015] By adopting the above technical solution, when the negative pressure mechanism is running, the adsorption holes on the push plate cooperate with the nail removal holes to remove the nails.
[0016] Preferably, the moving component further includes a bracket, a moving shaft, and a connecting frame. The bracket is mounted on the frame, the driving component is mounted on the bracket, and a U-shaped guide groove is provided on the side of the bracket opposite to the driving component. The moving shaft is located at the output end of the driving component, and a swing arm is mounted on the moving shaft. One end of the swing arm is located in the U-shaped guide groove, the connecting frame is connected to the swing arm, and the moving block is mounted on the connecting frame.
[0017] Preferably, the bracket is provided with a guide rail, and a guide slider is slidably connected to the guide rail. The guide slider is provided with a guide groove for the connecting bracket to be placed and slid.
[0018] By adopting the above technical solution, the driving component drives the moving shaft to rotate, which in turn drives the swing arm to rotate. The swing arm drives the connecting frame to move back and forth along the U-shaped guide groove, thereby driving the moving block and the nail-retrieving block to move back and forth. This facilitates the assembly of the staples into the staple cartridge, while limiting the movement path of the nail-retrieving block to further improve the accuracy of the staple assembly.
[0019] Preferably, both ends of the guide rail are provided with limiting members, and the guide slider is provided with a limiting sensor. The limiting sensor is electrically connected to the driving member. When the limiting sensor abuts against the limiting member, it sends a signal to the driving member, and the driving member receives the signal and adjusts the rotation direction.
[0020] By adopting the above technical solution, the limit sensor and the limit component work together to set and adjust the running rotation direction of the drive component, so as to facilitate the drive component to drive the connecting frame and the moving block to move back and forth.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. The moving block drives the nail-removing block to pick up and move the nail. When the nail-removing block moves to the position corresponding to the nail cartridge, the limiting component cooperates with the nail-removing block to limit the position of the staple to be assembled. Then the negative pressure mechanism stops running, and the staple falls into the staple cartridge under the action of gravity. With the cooperation of the limiting component, not only is the nail-removing efficiency improved, but the consistency of the relative position between the staple and the staple cartridge can also be ensured, reducing the probability of misalignment when the staple is installed.
[0023] 2. The driving component drives the moving shaft to rotate, which in turn drives the swing arm to rotate. The swing arm drives the connecting frame to move back and forth along the U-shaped guide groove, thereby driving the moving block and the nail-picking block to move back and forth. This facilitates the assembly of the staples into the staple cartridge and limits the movement path of the nail-picking block, further improving the accuracy of the staple assembly.

Detailed Implementation
[0028] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a staple removal device for staple assembly, such as... Figure 1 As shown, the device includes a frame 1, a moving component 2, and a nail-removing component 3. The frame 1 is equipped with a feeding mechanism 5 and a nail magazine 6. The matching nails are moved to the position to be removed by the feeding mechanism 5. The moving component 2 and the nail-removing component 3 are both located on the frame 1. The moving component 2 drives the nail-removing component 3 to move back and forth between the feeding mechanism 5 and the nail magazine 6 on the frame 1, so as to pick up the matching nails from the feeding mechanism 5 and assemble them into the nail magazine 6, thereby realizing automated nail removal and loading.
[0031] like Figure 2 and 3 As shown, the moving component 2 includes a moving block 21, a driving component 22, a bracket 23, a moving shaft 221, and a connecting frame 26. The bracket 23 is fixedly connected to the frame 1. The driving component 22 is a drive motor, which is fixedly connected to the bracket 23. A U-shaped guide groove 231 is provided on the side of the bracket 23 away from the drive motor. The moving shaft 221 is located at the end of the output shaft of the drive motor. A swing arm 25 is fixedly connected to the moving shaft 221. The end of the swing arm 25 away from the moving shaft 221 is located in the U-shaped guide groove 231. The connecting frame 26 is rotatably connected to the swing arm 25. The moving block 21 is fixedly connected to the end of the connecting frame 26 away from the swing arm 25.
[0032] like Figure 2 and 3As shown, the bracket 23 is also provided with a guide rail 24, and a guide slider 27 is slidably connected to the guide rail 24. The guide slider 27 is provided with a guide groove 271 for the connecting frame 26 to be placed and slide. Limiting members 28 are fixedly connected to both ends of the guide rail 24. Limiting sensors 272 are fixedly connected to the guide slider 27. The limiting sensors 272 are electrically connected to the drive motor. When the limiting sensors 272 abut against the limiting members 28, they send a signal to the drive motor. The drive motor receives the signal and adjusts the rotation direction.
[0033] The driving component 22 drives the moving shaft 221 to rotate, which in turn drives the swing arm 25 to rotate. The swing arm 25 drives the connecting frame 26 to move back and forth along the U-shaped guide groove 231.
[0034] like Figure 2 and 3 As shown, the staple removal assembly 3 includes a staple removal block 31, a negative pressure mechanism, a push plate 33, and a push cylinder 32. The staple removal block 31 is connected to the negative pressure mechanism (not shown in the figure) and is fixedly connected to the moving block 21. The staple removal block 31 has a hollow cavity and several staple removal holes on the side of the staple removal block 31 facing the frame 1. The push cylinder 32 is fixedly connected to the staple removal block 31, and the push plate 33 is fixedly connected to the end of the piston rod of the push cylinder 32. Several suction holes are provided on the push plate 33. When removing staples, the staple removal block 31 is aligned with the staple, the negative pressure mechanism operates, and the staple is sucked up by negative pressure and moved. However, when it moves to the corresponding position of the staple cartridge 6, the push cylinder 32 is activated to move the push plate 33, pushing the staple into the staple cartridge 6, and the negative pressure mechanism stops at the same time.
[0035] like Figure 2 and 3 As shown, it also includes a limiting assembly 4, which includes a limiting cylinder 41, a limiting plate 42, and a limiting rod 43. Two limiting plates 42 and two limiting rods 43 are provided, and both are slidably connected to the staple-removing block 31. The two limiting plates 42 are positioned opposite each other on both sides of the staple, and the two limiting rods 43 are positioned opposite each other at both ends of the staple. The two limiting plates 42 and the two limiting rods 43 are connected to each other by a limiting connecting rod 44, which is fixedly connected to the end of the piston rod of the limiting cylinder 41. Before the staple is inserted, the limiting cylinder 41 is activated, causing the limiting plates 42 and the limiting rods 43 to extend synchronously out of the staple-removing block 31, thus limiting the position of the staple. Then, the push plate 33 pushes the staple into the staple chamber 6.
[0036] The implementation principle of a staple removal device for staple assembly in this application embodiment is as follows:
[0037] The moving block 21 drives the nail-removing block 31 to pick up and move the nail. When the nail-removing block 31 moves to the position corresponding to the nail magazine 6, the limiting cylinder 41 is activated to drive the limiting plate 42 and the limiting rod 43 to extend. Then, the cylinder 32 and the push plate 33 are pushed to run, limiting the position of the staple to be assembled. Then, the negative pressure mechanism stops running. Under the pushing force of the push plate 33 and the gravity of the staple itself, it falls into the staple magazine 6. With the cooperation of the limiting component 4, not only is the nail-removing efficiency improved, but the consistency of the relative position between the staple and the staple magazine 6 is also ensured, reducing the probability of misalignment when the staple is installed.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
