[0001] This utility model relates to the field of stapler pad technology, specifically a multi-layer positioning and cutting device for stapler pads to prevent displacement. Background Technology

[0002] Anastomosis pads are a key component of medical staplers, primarily used to enhance anastomotic stability, distribute pressure, reduce tissue damage, and improve surgical safety and outcomes.

[0003] In the production process of stapler pads, a cutting device is required to cut sheet materials. Existing cutting devices have relatively simple functions, generally cutting single pieces of raw materials. When the sheet material moves to the lower part of the punching die, its position is prone to shifting. Moreover, after each punching, workers need to collect the cut stapler pads that have been separated from the sheet material, which is time-consuming and labor-intensive. Therefore, there is a need to provide a multi-layer positioning cutting device for stapler pads that prevents shifting, in order to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a multi-layer positioning and cutting device for anti-displacement stapler pads, which solves the problems mentioned in the background.

There are two positioning plates, which are respectively located at the lower ends of the two sides inside the mounting frame. The limiting slide rod is located on the side opposite to the two positioning plates. Sliding holes are provided on both sides of the mounting frame.

[0006] Preferably, the punching structure includes a hydraulic cylinder, a piston rod, and an upper die. The hydraulic cylinder is disposed on the upper surface of the mounting frame, the piston rod is disposed inside the hydraulic cylinder, and the lower end of the piston rod passes through the upper wall of the mounting frame and is connected to the upper die.

[0007] Preferably, the upper mold includes a template and an annular cutter. The template is connected to a piston rod. The annular cutter array is disposed on the lower end surface of the template. The annular cutter has an clearance groove. The lower mold has an annular groove corresponding to the annular cutter.

[0008] Preferably, the positioning component further includes a base frame, a bidirectional motor, threaded rods, and an end bracket. The base frame is located at the center of the lower surface of the worktable, the bidirectional motor is located inside the base frame, and there are two threaded rods.

[0009] Preferably, the two threaded rods are connected to the two output ends of the bidirectional motor at one end close to each other, the end bracket is disposed at the end of the threaded rod away from the bidirectional motor, the threaded rod is rotatably connected to the end bracket, and the upper end of the end bracket is connected to the side wall of the mounting bracket.

[0010] Preferably, the external threads on the outer surfaces of the two threaded rods at their opposite ends are in opposite directions, and a T-shaped connecting plate is threaded onto the threaded rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This anti-deviation stapler pad multi-layer positioning and cutting device, through the setting of positioning components and the operation of a bidirectional motor, can effectively drive two threaded rods to rotate synchronously. Through the rotation of the threaded rods, and under the limiting action of the end frame, the two T-shaped connecting plates can move along the threaded rods and approach each other. During the process of the two T-shaped connecting plates approaching each other, the limiting slide rod can push the two positioning plates to approach each other, adjusting the position of the sheet material to be in the center, avoiding the sheet material being in a deviated state during cutting, and ensuring product quality.

[0014] 2. This anti-deviation stapler pad multi-layer positioning and cutting device, through the setting of a punching structure, when the multi-layer sheet material moves to the upper surface of the lower mold and is adjusted in position, the hydraulic cylinder works, and the piston rod extends downward, which can effectively drive the upper mold to move down. The upper mold can cooperate with the lower mold, and can effectively cut the multi-layer sheet material according to the length of the annular cutter.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 A multi-layer positioning and cutting device for an anti-displacement stapler pad includes a worktable 1. The worktable 1 has mounting grooves 101 on both sides of the middle part. The upper surface of the worktable 1 is provided with a mounting frame 4 through the mounting grooves 101. The lower mold 3 is provided at the center of the upper surface of the worktable 1. The mounting frame 4 is provided with a punching structure 5. The lower surface of the worktable 1 is provided with a positioning component 6. The upper surface of the worktable 1 is provided with guides 7 at both ends. The positioning component 6 includes a limiting slide rod 606 and a positioning plate 607. There are two positioning plates 607, which are respectively located at the lower ends of the two sides inside the mounting frame 4. The limiting slide rod 606 is located on one side away from each other of the two positioning plates 607. Sliding holes 401 are provided on both sides of the mounting frame 4.

[0019] The punching structure 5 includes a hydraulic cylinder 501, a piston rod 502, and an upper die 503. The hydraulic cylinder 501 is located on the upper surface of the mounting frame 4, and the piston rod 502 is located inside the hydraulic cylinder 501. The lower end of the piston rod 502 passes through the upper wall of the mounting frame 4 and is connected to the upper die 503. The upper die 503 includes a template 5031 and an annular cutter 5032. The template 5031 is connected to the piston rod 502, and the annular cutters 5032 are arranged in an array on the lower surface of the template 5031. The annular cutters 5032 have clearance slots 5033. The lower die... The upper die 503 has an annular groove 301 corresponding to the annular cutter 5032. When the multi-layer sheet material moves to the upper surface of the lower die 3 and is adjusted, the hydraulic cylinder 501 works and extends downward through the piston rod 502, which can effectively drive the upper die 503 to move downward. The upper die 503 can cooperate with the lower die 3 to achieve effective cutting of the sheet material. Since the annular cutter 5032 has an avoidance groove 5033, the cut stapler pads will not directly detach from the sheet material, eliminating the need for staff to collect them one by one, saving time and effort.

[0020] The positioning component 6 also includes a base frame 601, a bidirectional motor 602, a threaded rod 603, and an end bracket 604. The base frame 601 is located at the center of the lower surface of the worktable 1. The bidirectional motor 602 is located inside the base frame 601. There are two threaded rods 603, with one end of each threaded rod close to the other connected to the two output ends of the bidirectional motor 602. The end bracket 604 is located at the end of the threaded rod 603 away from the bidirectional motor 602. The threaded rod 603 is rotatably connected to the end bracket 604. The upper end of the end bracket 604 is connected to the side wall of the mounting frame 4. The base frame 601 facilitates the installation of the bidirectional motor 602 and the threaded rod 603. The end bracket 604 effectively provides limiting support for the ends of the threaded rods 603. When the bidirectional motor 602 operates, it can effectively drive the two threaded rods 603 to rotate synchronously.

[0021] The two threaded rods 603 have opposite external threads on their outer surfaces at opposite ends. T-shaped connecting plates 605 are threaded onto the threaded rods 603. A limiting slide rod 606, at its end away from the positioning plate 607, passes through a sliding hole 401 and connects to the T-shaped connecting plate 605. The limiting slide rod 606 is slidably connected to the mounting bracket 4. As the threaded rods 603 rotate and are limited by the end bracket 604, the two T-shaped connecting plates 605 can move along the threaded rods 603 and approach each other. During this approach, the limiting slide rod 606 can push the two positioning plates 607 closer together, adjusting the position of the sheet material to the center, preventing the sheet material from being offset during cutting, and ensuring product quality.

[0022] The guide component 7 includes a U-shaped mounting frame 701 and a guide roller 702. The U-shaped mounting frame 701 is set on the upper surface of the worktable 1, and the guide roller 702 is rotatably set inside the U-shaped mounting frame 701. The U-shaped mounting frame 701 facilitates the installation of the guide roller 702. The guide roller 702 can effectively guide the multi-layer sheet material and facilitate the movement of the sheet material to the bottom of the punching structure 5.

[0023] The workbench 1 has brackets 2 at both ends of its lower surface. The bottom of the brackets 2 has fixing holes. The brackets 2 can effectively support the workbench 1. The fixing holes facilitate the use of fixing bolts to fix the brackets 2, ensuring the overall stability.

[0024] The working principle is as follows: the bidirectional motor 602 can effectively drive the two threaded rods 603 to rotate synchronously. With the rotation of the threaded rods 603 and the limiting action of the end frame 604, the two T-shaped connecting plates 605 can move along the threaded rods 603 and approach each other. During the process of the two T-shaped connecting plates 605 approaching each other, the limiting slide rod 606 can push the two positioning plates 607 to approach each other, adjusting the position of the sheet material to be in the center, avoiding the sheet material being offset during cutting, and ensuring product quality.

[0025] Furthermore, by setting up the punching structure 5, when the sheet material moves to the upper surface of the lower mold 3 and is adjusted in position, the hydraulic cylinder 501 works, and the piston rod 502 extends downward, which can effectively drive the upper mold 503 to move down. The upper mold 503 can cooperate with the lower mold 3, and can effectively cut multi-layer sheet materials according to the length of the annular cutter 5032. Moreover, since the annular cutter 5032 has an avoidance groove 5033, the cut stapler pads will not directly detach from the sheet material, so that the staff does not need to collect them one by one, saving time and effort.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
