Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, and in particular to a punching tool for a buffer pad. Background Technology

[0002] In cardiac, vascular, and some orthopedic surgeries, non-absorbable sutures (such as polypropylene or polyester sutures) are often used to provide permanent support. To distribute the pressure of the sutures on fragile tissues and prevent them from cutting tissues when knotted or during heartbeats, pads (such as small cotton pads or felt pads) are usually placed on the sutures.

[0003] When assembling the gasket and suture, holes need to be pre-drilled at the fixed positions on the gasket to allow the suture to pass through. Currently, traditional manual punching methods mostly use a hand-held needle, which has the following drawbacks: First, the punching efficiency is low and cannot meet production needs; second, manual operation is prone to causing hole misalignment, resulting in uneven pressure distribution after suturing, affecting the protective effect of the gasket, and in severe cases, even causing the gasket to break and fail to provide effective permanent support. Although gasket-type sutures are special products with relatively limited applicable surgical procedures and a small market demand, thus not requiring large-scale automated production capacity, the quality and efficiency issues of existing manual punching methods remain prominent in small-batch production scenarios.

[0004] Therefore, there is an urgent need for a tooling equipment specifically designed for small-batch production that can guarantee drilling accuracy and consistency. Utility Model Content

[0005] The purpose of this invention is to provide a punching fixture for buffer pads, which solves the technical problem of low quality and efficiency of existing manual punching methods in small-batch production scenarios.

[0006] To achieve the above objectives, this utility model provides a punching fixture for buffer pads, comprising:

[0007] A base, on which several guide rails are fixedly mounted;

[0008] Two horizontal slides are fitted onto the guide rail and slidably connected to the guide rail. One of the horizontal slides is fixedly provided with a striker fixing fixture, and the other horizontal slide is fixedly provided with a gasket fixing fixture. The striker fixing fixture is fixedly installed with a striker, and the gasket fixing fixture is used to fix and install a gasket.

[0009] At least one locking assembly, the locking assembly including a guide rod arranged parallel to the guide rail and slidably connected to the base, and a fastener disposed on the base; the fastener is configured to cooperate with the guide rod to fix the position of the horizontal slide table along the axial direction of the guide rail.

[0010] Preferably, the base includes a fixed plate and connecting plates vertically disposed on both sides of the fixed plate, the guide rail is fixedly disposed between the two connecting plates, and the guide rod is slidably connected to the connecting plates.

[0011] Preferably, the fastener is a fastening bolt, which is threadedly connected to the connecting plate of the base. When the fastening bolt is rotated, one end of the fastening bolt can press against the guide rod.

[0012] Preferably, the top of the horizontal slide is provided with a mounting groove for mounting a striker fixing fixture or a gasket fixing fixture.

[0013] Preferably, the two side walls of the mounting groove are threaded with first bolts, which are used to abut against the firing pin fixing fixture or the washer fixing fixture for fixing.

[0014] Preferably, the firing pin fixing fixture includes a fixing member and a connecting member that is detachably and fixedly connected to the fixing member. The fixing member is fixedly disposed in the mounting groove of the horizontal slide, and the connecting member has a plurality of firing pin grooves on the side near the fixing member.

[0015] Preferably, the firing pin groove is a V-shaped groove.

[0016] Preferably, the gasket fixing fixture is fixedly disposed in the mounting groove of the horizontal slide, and a gasket groove is provided on one side of the gasket fixing fixture.

[0017] Preferably, the gasket fixing fixture includes two separate components that are detachably fixedly connected.

Detailed Implementation

[0026] 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.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] This utility model provides a punching fixture for buffer pads. By setting a striker fixing fixture 3 and a pad fixing fixture 4, the accuracy and consistency of the thread hole positions of the pad 7 are ensured, so that the force applied by the sewing thread on the pad 7 can be evenly distributed, thereby improving product quality and production efficiency.

[0029] Please refer to this as well. Figures 1 to 4The punching fixture for the buffer pad provided by this utility model includes:

[0030] Base 1, on which several guide rails 101 are fixedly mounted;

[0031] Two horizontal slides 2 are fitted onto the guide rail 101 and slidably connected to the guide rail 101. One horizontal slide 2 is fixedly provided with a striker fixing fixture 3, and the other horizontal slide 2 is fixedly provided with a shim fixing fixture 4. The striker fixing fixture 3 is fixedly installed with a striker 6, and the shim fixing fixture 4 is used to fix and install a shim 7.

[0032] At least one locking assembly 5, the locking assembly 5 includes a guide rod 501 arranged parallel to the guide rail 101 and slidably connected to the base 1, and a fastener 502 provided on the base 1; the fastener 502 is configured to cooperate with the guide rod 501 to fix the position of the horizontal slide 2 along the axial direction of the guide rail 101.

[0033] The guide rail 101 is horizontally fixed on the base 1. Two horizontal slides 2 are fitted onto the guide rail 101 and can slide along the extension direction of the guide rail 101. One of the two horizontal slides 2 is fixedly equipped with a striker fixing fixture 3, and the other is fixedly equipped with a gasket fixing fixture 4. A striker 6 is fixedly installed on the striker fixing fixture 3, and the gasket fixing fixture 4 is used to fix a gasket 7. The locking assembly 5 is used to fix one of the horizontal slides 2 equipped with the striker fixing fixture 3, so that the other horizontal slide 2 equipped with the gasket fixing fixture 4 can move along the guide rail 101 toward the striker 6 on the striker fixing fixture 3, and the drilling is completed by the contact between the striker 6 and the gasket 7.

[0034] In use, the shim 7 to be drilled is fixed on the shim fixing fixture 4. After installation, the shim 7 corresponds to the striker 6 on the striker fixing fixture 3. The fastener 502 is operated to engage with the corresponding guide rod 501, thereby fixing the horizontal slide 2 with the striker fixing fixture 3 in position along the axis of the guide rail 101. This causes another horizontal slide 2 with the shim fixing fixture 4 to move along the guide rail 101 toward the striker 6 on the striker fixing fixture 3. The shim 7 gradually approaches and contacts the striker 6. As the shim 7 continues to move, the tip of the striker 6 pierces the shim 7, realizing the drilling operation. After drilling is completed, the horizontal slide 2 with the shim fixing fixture 4 is moved in the opposite direction, and finally the shim 7 is removed. It can be understood that multiple shims 7 can be fixed on the shim fixing fixture 4 at the same time during each drilling operation. The multiple shims 7 are stacked, so that the striker 6 can pierce multiple shims 7 at once, improving drilling efficiency.

[0035] This setup, with the pin fixing fixture 3 and the gasket fixing fixture 4, ensures precise alignment between the pin 6 and the gasket 7, guaranteeing accurate punching positions. The thread threading positions on the gasket 7 are evenly distributed, thus ensuring the design effect of the gasket 7 in dispersing seam pressure. The fixture-based operation avoids hole misalignment caused by human factors, resulting in consistent punching quality for each gasket 7. Compared to purely manual punching, it improves punching efficiency in small-batch production.

[0036] In some embodiments, the base 1 includes a fixed plate 102 and connecting plates 103 vertically disposed on both sides of the fixed plate 102, a guide rail 101 fixedly disposed between the two connecting plates 103, and a guide rod 501 slidably connected to the connecting plate 103.

[0037] Please refer to this as well. Figures 1 to 3 The base plate is roughly U-shaped, including a horizontally positioned fixed plate 102 and two connecting plates 103 located on both sides of the fixed plate 102 and perpendicular to it. A guide rail 101 is horizontally positioned between the two connecting plates 103, with both ends of the guide rail 101 fixedly connected to the two connecting plates 103 respectively. A guide rod 501 is horizontally positioned, with one end fixedly connected to the horizontal slide table 2. The connecting plate 103 of the base 1 has a through hole, through which the guide rod 501 passes, allowing it to slide slidably connect to the connecting plate 103 of the base 1.

[0038] In some embodiments, the fastener 502 is a fastening bolt, which is threadedly connected to the connecting plate 103 of the base 1. When the fastening bolt is rotated, one end of the fastening bolt can press against the guide rod 501.

[0039] Please refer to this as well. Figures 1 to 3 In this embodiment, the fastener 502 is a fastening bolt, which is vertically positioned and threaded to the top of the connecting plate 103. By rotating the fastening bolt, one end of the bolt can enter the through hole of the connecting plate 103 and abut against the top of the guide rod 501. When the fastening bolt abuts against the guide rod 501, the position of the horizontal slide 2 is locked. By loosening the fastening bolt, one end of the bolt is no longer abutting against the guide rod 501, thus unlocking the slide.

[0040] In some embodiments, the top of the horizontal slide 2 is provided with a mounting groove 201 for mounting the striker fixing fixture 3 or the gasket fixing fixture 4.

[0041] Please refer to this as well. Figures 1 to 2 A mounting groove 201 is provided at the top center of the horizontal slide 2. The cross-section of the mounting groove 201 is rectangular. The ejector pin fixing fixture 3 or the gasket fixing fixture 4 can be fixed to the corresponding horizontal slide 2 through the mounting groove 201.

[0042] In some embodiments, first bolts 202 are threaded onto both sides of the mounting groove 201. The first bolts 202 are used to abut against the firing pin fixing fixture 3 or the washer fixing fixture 4 for fixing.

[0043] Please refer to this as well. Figures 1 to 3 The left and right side walls of the mounting groove 201 are threaded with first bolts 202. The first bolts 202 are set in the horizontal direction and perpendicular to the extension direction of the guide rail 101. When the first bolts 202 on both sides of the mounting groove 201 are rotated, the ends of the two first bolts 202 can be pressed against the two sides of the firing pin fixing fixture 3 or the shim fixing fixture 4 respectively, thereby fixing the firing pin fixing fixture 3 or the shim fixing fixture 4. It is understandable that the mounting groove 201 is clearance-fitted with the firing pin fixing fixture 3 and the shim fixing fixture 4. The firing pin fixing fixture 3 or the shim fixing fixture 4 can move slightly within the mounting groove 201 in a direction perpendicular to the guide rail 101. By adjusting the screwing distance of the two first bolts 202, the firing pin fixing fixture 3 or the shim fixing fixture 4 can be fixed in different positions within the mounting groove 201, thereby finely adjusting the firing pin fixing fixture 3 or the shim fixing fixture 4 in a direction perpendicular to the length of the guide rail 101, so that the firing pin 6 on the firing pin fixing fixture 3 can be aligned with the shim 7 on the shim fixing fixture 4, ensuring drilling accuracy.

[0044] In some embodiments, the firing pin fixing fixture 3 includes a fixing member 301 and a connecting member 302 detachably and fixedly connected to the fixing member 301. The fixing member 301 is fixedly disposed in the mounting groove 201 of the horizontal slide table 2, and the connecting member 302 is provided with a plurality of firing pin grooves on the side near the fixing member 301.

[0045] Please refer to this as well. Figures 1 to 3 The firing pin fixing fixture 3 includes a fixing member 301 and a connecting member 302. The fixing member 301 is detachably fixed to the connecting member 302 by bolts. The connecting member 302 has multiple firing pin slots on the side near the fixing member 301. The firing pin 6 is installed and positioned in the firing pin slots. When the fixing member 301 and the connecting member 302 are connected, the firing pin 6 can be fixed on the firing pin fixing fixture 3. It can be understood that there are multiple firing pin slots, which are spaced apart. In use, by installing two firing pins 6 in different firing pin slots, the distance between the two firing pins 6 can be adjusted, which is suitable for drilling holes in gaskets 7 of different sizes.

[0046] In some embodiments, the firing pin groove is a V-groove.

[0047] When the V-groove contacts the cylindrical striking pin 6, two lines of contact are formed. Regardless of the diameter of the striking pin 6 (as long as it is within the capacity of the V-groove), under the clamping force, the axis of the striking pin 6 will naturally tend to fall on the symmetrical center line of the V-groove. This allows the operator to install the striking pin 6 without tedious fine adjustments; simply placing the striking pin 6 into the groove allows it to automatically and quickly achieve center positioning. This ensures the parallelism between multiple striking pins 6 and their perpendicularity to the shim 7, which is beneficial for achieving high-precision drilling. Furthermore, the two inclined surfaces of the V-groove contact the cylindrical surface of the striking pin 6, forming a stable two-point clamping structure. This effectively prevents the striking pin 6 from rotating or shifting when subjected to impact force (the instant it penetrates the shim 7), ensuring the stability and repeatability of the drilling process. Compared to planar clamping, the V-shaped surface significantly increases the resistance to rotation.

[0048] In some embodiments, the gasket fixing fixture 4 is fixedly disposed in the mounting groove 201 of the horizontal slide table 2, and a gasket groove 401 is provided on one side of the gasket fixing fixture 4.

[0049] Please refer to this as well. Figures 1 to 3 The gasket groove 401 is located on the side of the gasket fixing fixture 4 facing the striker fixing fixture 3. The gasket groove 401 is roughly rectangular, which makes it more compatible with the shape of the gasket 7, facilitating the placement of the gasket 7 inside the gasket groove 401. Different types of gaskets 7 can be placed in the gasket groove 401, ensuring that the width of the gasket 7 is consistent with the width of the gasket groove 401. Products whose length of the gasket 7 does not exceed the length of the gasket groove 401 are suitable. For example, when the dimensions of the gasket groove 401 are designed to be 7*3mm, then gaskets 7 with a width of 3mm and a length not exceeding 7mm are suitable.

[0050] In some embodiments, the gasket fixing fixture 4 includes two separate components that are separately configured and detachably fixedly connected.

[0051] Please refer to this as well. Figures 1 to 3 In this embodiment, the gasket fixing fixture 4 may include two separate parts that are separately set and detachably fixedly connected. The two separate parts can be connected by bolts, and the two separate parts are assembled to form a gasket groove 401.

[0052] In some embodiments, there are two guide rails 101, which are arranged in parallel and located on both sides of the horizontal slide 2.

[0053] Please refer to this as well. Figures 1 to 2 In this embodiment, two guide rails 101 are provided, with the two guide rails 101 located on both sides of the horizontal slide 2, ensuring that the horizontal slide 2 can move smoothly and accurately along the extension direction of the guide rails 101 without deflection. In other embodiments, the number of guide rails 101 may be greater.

[0054] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0055] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
