Abstract
Description
Technical Field
[0001] This utility model belongs to the field of suture needle technology, and more specifically, it relates to a suture needle drilling device that facilitates positioning. Background Technology
[0002] As a crucial component in medical devices used for tissue suturing and ligation, the precision of suture needle manufacturing directly impacts clinical efficacy. During suture needle production, because the needle body is curved and a suture hole needs to be machined at the flat end, a positioning device is required to ensure the accuracy of the hole's position, diameter, and wall roughness.
[0003] Existing positioning devices are typically fixedly connected to the processing table, resulting in a rigid spatial layout. When operators place tiny suture needles into the positioning area, this fixed structure significantly reduces hand operating space, greatly increasing the risk of accidental contact with the positioning components by hands or tools, or obstruction of vision. These disturbances force frequent adjustments during the operation, severely reducing placement efficiency and increasing the risk of suture needle surface damage due to repeated unnecessary contact between the needle and the positioning components. Utility Model Content
[0004] In view of the problem that when placing tiny suture needles into the positioning device, accidental contact with the positioning component by hand or tool or obstruction of vision is very likely, this utility model proposes a suture needle drilling device that facilitates positioning, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a suture needle drilling device for easy positioning, including a processing table. A drilling component and a clamping component are provided on the top of the processing table. An insertion positioning component is provided between the clamping component and the processing table. A limit component is provided on the top of the processing table corresponding to the insertion positioning component. An elastic pulling component is provided at the bottom of the processing table. The elastic pulling component is connected to the limit component.
[0007] The clamping assembly is used to clamp and fix the suture needle. The insertion positioning assembly positions the suture needle through the clamping assembly. The elastic pulling assembly is used to pull the limiting end of the limiting assembly so that the limiting end limits the clamping assembly on the processing table.
[0008] Furthermore, the drilling assembly includes a mounting frame, which is fixedly mounted on the top of the processing table. A lifting screw is rotatably connected inside the mounting frame, and a lifting bracket is threadedly connected to the outer surface of the lifting screw. A drilling motor is fixedly mounted inside the lifting bracket, and a drill bit is fixedly mounted on the output end of the drilling motor. A lifting motor is fixedly mounted on the top of the mounting frame, and the output end of the lifting motor is fixedly connected to the lifting screw. A fixing rod is fixedly connected inside the mounting frame, and the fixing rod is movably connected to the lifting bracket.
[0009] Furthermore, the clamping assembly includes a placement frame, which is disposed on the top of the processing table. A placement groove and a limiting groove are provided on one side of the placement frame. A T-shaped limiting block is movably connected inside the limiting groove, and a clamping plate is fixedly connected to one side of the T-shaped limiting block.
[0010] Furthermore, an L-shaped rotating plate is rotatably connected to the top of the clamping plate, a locking bolt is threaded to one side of the L-shaped rotating plate, one end of the locking bolt passes through the L-shaped rotating plate and is fixedly connected to a pressing plate, and the other end of the locking bolt is fixedly connected to a control plate.
[0011] Furthermore, the insertion positioning assembly includes positioning holes, and multiple positioning holes are provided on the top of the processing table. A positioning rod is movably connected inside the positioning hole, and the positioning rod is fixedly connected to the placement frame.
[0012] Furthermore, the limiting component includes an L-shaped pick-up plate, which is fixedly connected to the other side of the placement frame. An L-shaped limiting plate is movably connected to the top of the L-shaped pick-up plate. A fixing frame is fixedly installed at the bottom of the processing table. A T-shaped guide rod is movably connected to one side of the fixing frame. One end of the T-shaped guide rod is fixedly connected to the back of the L-shaped limiting plate. A handle is fixedly connected to the front of the L-shaped limiting plate.
[0013] Furthermore, the elastic pulling assembly includes a storage tube, which is fixedly connected to a fixing frame. A T-shaped pulling rod is movably connected inside the storage tube. One end of the T-shaped pulling rod passes through the storage tube and is fixedly connected to the back of an L-shaped limiting plate. A push spring is fixedly connected between the other end of the T-shaped pulling rod and the inner wall of the storage tube.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model can clamp and fix the suture needle through the clamping component. The plug-in positioning component can make the position of the suture needle in the clamping component correspond vertically with the drilling component. At the same time, the limiting component can limit the clamping component under the pull of the elastic pulling component, so that the clamping component will not detach from the processing table. The above settings allow the clamping component to be quickly disassembled from the processing table, thereby allowing the suture needle to be clamped and fixed outside the processing table. This not only improves the convenience of hand operation, but also effectively avoids frequent adjustment of the suture needle during placement.
[0016] 2. This utility model moves the flat end of the suture needle into the placement groove, then moves the T-shaped limiting block into the limiting groove, causing the clamping plate to move inside the placement frame and clamp and fix the suture needle. Then, the L-shaped rotating plate rotates and the clamping plate is locked by the locking bolt and the control panel. The clamping plate that can move out from inside the placement frame ensures that the operator's view is not obstructed when the suture needle is moved into the placement frame, making the operation of placing the suture needle more convenient.
[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation
[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0031] Please see Figures 1-8 As shown, this utility model is a suture needle drilling device for easy positioning, including a processing table 1. The top of the processing table 1 is provided with a drilling component 2 and a clamping component 3. An insertion positioning component 4 is provided between the clamping component 3 and the processing table 1. A limiting component 5 is provided on the top of the processing table 1 corresponding to the insertion positioning component 4. An elastic pulling component 6 is provided on the bottom of the processing table 1. The elastic pulling component 6 is connected to the limiting component 5.
[0032] The clamping component 3 is used to clamp and fix the suture needle. The insertion positioning component 4 positions the suture needle through the clamping component 3. The elastic pulling component 6 is used to pull the limiting end of the limiting component 5 so that the limiting end limits the clamping component 3 on the processing table 1.
[0033] After the suture needle is clamped and fixed by the clamping component 3 on the outside of the device, the clamping component 3 is placed on the top of the processing table 1 by the insertion positioning component 4. Then, the elastic pulling component 6 pulls the limiting component 5, so that the limiting component 5 limits the insertion positioning component 4. After the insertion positioning component 4 and the limiting component 5 work together to fix the clamping component 3, the drilling end of the drilling component 2 begins to drill holes in the suture needle clamped by the clamping component 3.
[0034] The clamping component 3 can clamp and fix the suture needle. The insertion positioning component 4 can make the position of the suture needle hole inside the clamping component 3 correspond vertically to the drilling component 2. At the same time, the limiting component 5 can limit the clamping component 3 under the pull of the elastic pulling component 6, so that the clamping component 3 will not detach from the processing table 1. The above settings allow the clamping component 3 to be quickly removed from the processing table 1, thereby allowing the suture needle to be clamped and fixed outside the processing table 1. This not only improves the convenience of hand operation, but also effectively avoids frequent adjustments to the suture needle during placement.
[0035] In one embodiment, the drilling assembly 2 includes a mounting bracket 201, which is fixedly mounted on the top of the processing table 1. A lifting screw 202 is rotatably connected inside the mounting bracket 201, and a lifting frame 203 is threadedly connected to the outer surface of the lifting screw 202. A drilling motor 204 is fixedly mounted inside the lifting frame 203, and a drill bit 205 is fixedly mounted at the output end of the drilling motor 204. A lifting motor 206 is fixedly mounted on the top of the mounting bracket 201, and the output end of the lifting motor 206 is fixedly connected to the lifting screw 202. A fixing rod 207 is fixedly connected inside the mounting bracket 201, and the fixing rod 207 is movably connected to the lifting frame 203.
[0036] The lifting motor 206 drives the lifting screw 202 to rotate. At this time, the lifting frame 203 can move downward under the drive of the lifting screw 202 and the guidance of the fixed rod 207. At the same time, the drilling motor 204 inside the lifting frame 203 can drive the drill bit 205 to rotate, so that the drill bit 205 can rotate downward and thus complete the drilling operation of the suture needle.
[0037] In one embodiment, the clamping assembly 3 includes a placement frame 301, which is disposed on the top of the processing table 1. A placement groove 302 and a limiting groove 303 are provided on one side of the placement frame 301. A T-shaped limiting block 304 is movably connected inside the limiting groove 303. A clamping plate 305 is fixedly connected to one side of the T-shaped limiting block 304.
[0038] By moving the flat end of the suture needle into the placement groove 302 and bringing it into contact with the inner wall of the placement frame 301, and then moving the T-shaped limiting block 304 into the limiting groove 303, the clamping plate 305 can move inside the placement frame 301 to clamp and fix the suture needle. The clamping plate 305 will not arbitrarily detach from the placement frame 301. The clamping plate 305, which can move out of the placement frame 301, ensures that the operator's view is not obstructed when moving the suture needle into the placement frame 301, making the placement of the suture needle more convenient. Furthermore, since the placement groove 302 limits the suture needle as a whole, the clamping plate 305 can fix the suture needle as a whole, preventing it from shaking during punching operations.
[0039] In one embodiment, for the clamping plate 305, an L-shaped rotating plate 306 is rotatably connected to the top of the clamping plate 305, a locking bolt 307 is threadedly connected to one side of the L-shaped rotating plate 306, one end of the locking bolt 307 passes through the L-shaped rotating plate 306 and is fixedly connected to a pressing disc 308, and the other end of the locking bolt 307 is fixedly connected to a control disc 309.
[0040] After the clamping plate 305 engages with the inner wall of the placement frame 301 to clamp and fix the suture needle, the L-shaped rotating plate 306 is rotated to the other side of the placement frame 301. At the same time, the locking bolt 307 is rotated by the control disc 309, causing the locking bolt 307 to move and come into contact with the placement frame 301. At this time, the locking bolt 307 can lock the clamping plate 305 through the L-shaped rotating plate 306. The above arrangement ensures that the clamping plate 305 will not move arbitrarily inside the placement frame 301 when clamping and fixing the suture needle, thus ensuring the firmness of the clamping.
[0041] In one embodiment, the above-mentioned plug-in positioning component 4 includes a positioning hole 401, a plurality of positioning holes 401 are provided on the top of the processing table 1, and a positioning rod 402 is movably connected inside the positioning hole 401, and the positioning rod 402 is fixedly connected to the placement frame 301.
[0042] After the suture needle is clamped and fixed, the positioning rod 402 at the bottom of the placement frame 301 is moved into the positioning hole 401, so that the positioning hole 401 can quickly position the placement frame 301 through the positioning rod 402, so that after the placement frame 301 is placed on the processing table 1, the suture needle clamped inside can directly correspond vertically with the drill bit 205.
[0043] In one embodiment, the limiting component 5 includes an L-shaped pick-up plate 501, which is fixedly connected to the other side of the placement frame 301. An L-shaped limiting plate 502 is movably connected to the top of the L-shaped pick-up plate 501. A fixing frame 503 is fixedly installed at the bottom of the processing table 1. A T-shaped guide rod 504 is movably connected to one side of the fixing frame 503. One end of the T-shaped guide rod 504 is fixedly connected to the back of the L-shaped limiting plate 502. A handle 505 is fixedly connected to the front of the L-shaped limiting plate 502.
[0044] After placing the placement frame 301 on top of the processing table 1 using the L-shaped pick-up plate 501, the L-shaped limiting plate 502 is moved to the top of the L-shaped pick-up plate 501 using the handle 505. This allows the L-shaped limiting plate 502 to limit the placement frame 301, preventing it from shaking when the suture needle is drilling. In the above configuration, the T-shaped guide rod 504 can move on the fixed frame 503 under the drive of the L-shaped limiting plate 502. The T-shaped guide rod 504 guides the movement of the L-shaped limiting plate 502 through the fixed frame 503, ensuring the stability of the L-shaped limiting plate 502 during movement. At the same time, the L-shaped limiting plate 502 will not move off the processing table 1 arbitrarily due to the restriction of the T-shaped guide rod 504.
[0045] In one embodiment, the elastic pulling component 6 includes a storage cylinder 601, which is fixedly connected to a fixing frame 503. A T-shaped pulling rod 602 is movably connected inside the storage cylinder 601. One end of the T-shaped pulling rod 602 passes through the storage cylinder 601 and is fixedly connected to the back of an L-shaped limiting plate 502. A push spring 603 is fixedly connected between the other end of the T-shaped pulling rod 602 and the inner wall of the storage cylinder 601.
[0046] The push spring 603 can push the L-shaped limiting plate 502 through the T-shaped pull rod 602, so that the L-shaped limiting plate 502 can move directly onto the L-shaped take-up plate 501. Under the push of the push spring 603, the L-shaped limiting plate 502 will not move arbitrarily when limiting the L-shaped take-up plate 501. At the same time, when releasing the limitation on the L-shaped take-up plate 501, the L-shaped limiting plate 502 can be pulled directly through the handle 505, which is relatively convenient to operate.
[0047] Through the above technical solution, 1. the clamping component 3 can clamp and fix the suture needle, and the insertion positioning component 4 can make the position of the suture needle hole inside the clamping component 3 correspond vertically to the drilling component 2. At the same time, the limiting component 5 can limit the clamping component 3 under the pull of the elastic pulling component 6, so that the clamping component 3 will not detach from the processing table 1. The above settings allow the clamping component 3 to be quickly removed from the processing table 1, thereby allowing the suture needle to be clamped and fixed outside the processing table 1. This not only improves the convenience of hand operation, but also effectively avoids frequent adjustments to the suture needle during placement. 2. After moving the flat end of the suture needle into the placement groove 302, the T-shaped limiting block 304 is moved into the limiting groove 303, and the clamping plate 305 moves inside the placement frame 301 to clamp and fix the suture needle. Then, the L-shaped rotating plate 306 rotates and the clamping plate 305 is locked by the locking bolt 307 and the control panel 309. The clamping plate 305 that can move out of the placement frame 301 in the above setting ensures that the operator's line of sight is not obstructed when the suture needle is moved into the placement frame 301, making the operation of placing the suture needle more convenient.
