Description
Technical Field
[0001] The utility model relates to a suture needle and thread combining device, in particular to a device for quickly combining a suture needle and a suture thread. Background Art
[0002] In order to improve the convenience and reliability of the product, the current suture needle and suture thread are generally packaged in one piece, that is, the suture needle and suture thread are combined into a unified whole before being packaged and sold. Compared with the traditional needle eye design, the tail of the existing suture needle is designed to be cylindrical. After the bonding glue is pressed into the tail tube, the suture thread is inserted, and the tail tube of the suture needle is pressed tightly by equipment to fix the suture thread in the tail tube.
[0003] The existing process of combining suture needles and suture threads mainly relies on highly automated equipment. However, in actual operation, we found that these automated equipment, which integrate a large number of sensors and transmission devices, not only has high procurement costs, but also considerable maintenance costs in the later stage. For this reason, it is difficult to increase the number of these devices on a large scale. Once a device fails, the production process will be seriously affected and may even lead to shutdown.
[0004] In view of this, we urgently need to design a new device that can quickly and effectively complete the combination of suture needles and suture threads when the automated equipment fails, thereby ensuring the continuity and stability of production and reducing the risks caused by equipment failure. Utility Model Content
[0005] The utility model aims to provide a device for quickly combining a suture needle and a suture thread, so as to solve the problems described in the background technology.
[0006] The technical solution of the utility model is achieved in this way:
[0007] A device for quickly combining a suture needle and a suture thread, comprising a bottom plate. At the upper end of the bottom plate, a transverse slide rail extending in the front-rear direction is fixedly provided. A transverse baffle is provided at the rear end of the transverse slide rail. At the upper end of the bottom plate on the right side of the middle part of the transverse slide rail, a longitudinal slide rail perpendicular to the transverse slide rail is fixedly provided. A longitudinal baffle is provided on the left side of the longitudinal guide rail. A needle-carrying slider is slidably connected to the transverse slide rail, and a glue-carrying slider is slidably connected to the longitudinal slide rail. A fixed clamp block is further provided in the rear side direction of the transverse slide rail, and a movable clamp block is further provided on the right side of the fixed clamp block. A driving mechanism for driving the movable clamp block to move left and right is further provided at the upper end of the bottom plate. A thread-passing seat is further provided in the rear side direction of the fixed clamp block. A downwardly opened needle groove is provided on the upper end surface of the needle-carrying slider. One end of the needle groove communicates with the rear side wall of the needle-carrying slider to form a needle tail outlet. A glue injection mechanism is provided on the glue-carrying slider. A thread-passing cover is detachably covered on the upper end surface of the thread-passing seat. Thread-passing grooves extending in the front-rear direction are provided on the joint surfaces of the thread-passing seat and the thread-passing cover. When the upper and lower two thread-passing grooves are combined, a complete columnar groove and a conical groove are formed. The front end of the columnar groove communicates with the front side walls of the thread-passing seat and the thread-passing cover. The front end of the conical groove is small and communicates with the columnar groove. The rear end of the conical groove is large and communicates with the rear side walls of the thread-passing seat and the thread-passing cover.
[0008] When using the above solution, place the suture needle into the needle groove of the needle-carrying slider, and make the tail cylinder of the suture needle pass out from the needle tail outlet. Then slide the glue-carrying slider to the left until the glue-carrying slider abuts against the longitudinal baffle for limiting. Slide the needle-carrying slider backward so that the tail cylinder is aligned with the glue injection mechanism. Use the glue injection mechanism to inject the bonding glue into the tail cylinder. Then slide the glue-carrying slider to the right to make the glue-carrying slider leave the sliding range of the needle-carrying slider. Then continue to slide the needle-carrying slider backward until the needle-carrying slider abuts against the transverse baffle. When the needle-carrying slider abuts against the transverse baffle, the tail cylinder is exactly between the fixed clamp block and the movable clamp block, and the tail cylinder is exactly aligned with the columnar groove. At this time, insert the suture thread into the rear end of the conical groove and continuously insert it forward until the suture thread is inserted into the tail cylinder. Then use the driving mechanism to drive the movable clamp block to move leftward, so that the movable clamp block and the fixed clamp block gradually clamp the tail cylinder, thereby clamping the suture thread by deforming the tail cylinder. When the suture thread and the suture needle are combined, open the thread-passing cover and move the right clamp block to quickly remove the suture needle and the suture thread.
[0009] By setting the longitudinal baffle and the transverse baffle, this device can enable the needle-carrying slider and the glue-carrying slider to quickly reach the preset positions for glue injection and wire feeding operations.
[0010] By setting the movable glue-carrying slider and mounting the glue injection mechanism, this device makes glue injection more convenient.
[0011] By setting the thread-passing groove including the columnar groove and the conical groove, this device enables the suture thread to be quickly aligned and fed into the tail cylinder of the suture needle and relatively fixed, facilitating the quick clamping and fixing of the fixed clamp block and the movable clamp block.
[0012] By providing an openable and closable thread-passing cover, the suture needle and the suture can be quickly taken out after being combined.
[0013] A further technical solution is that the glue injection mechanism includes a convex block fixedly arranged on the upper end surface of the glue-carrying slider. The convex block is arranged at the front end of the upper end surface of the glue-carrying slider. A glue injection hole extending in the front-rear direction is arranged in the convex block. The front end of the glue injection hole communicates with the front side wall of the convex block, and the rear end of the glue injection hole communicates with the rear side wall of the convex block. The glue injection mechanism further includes a glue cylinder groove opened on the upper end surface of the glue-carrying slider. The glue cylinder groove is arranged at the rear end of the convex block and extends in the front-rear direction. A limiting cover for covering the glue cylinder groove is further arranged on the upper end of the glue-carrying slider. The glue injection mechanism further includes a convex top arranged on the front side wall of the glue-carrying slider. The convex top is made of an elastic material. When the rear end surface of the needle-carrying slider abuts against the convex top, the tail needle outlet is exactly aligned with the front end of the glue injection hole.
[0014] When using the above solution, insert the glue injection cylinder into the glue cylinder groove so that the outlet of the glue injection cylinder is aligned with the rear end of the glue injection hole. After placing the suture needle in the needle groove, move the needle-carrying slider to abut against the convex top and squeeze the convex top. The tail cylinder just abuts against the front end of the glue injection hole. By squeezing the glue injection cylinder, the glue is extruded, and the glue is injected into the tail cylinder through the glue injection hole to complete the glue injection of the tail cylinder. Then move the needle-carrying slider forward and move the glue-carrying slider to the right to perform the next operation.
[0015] By providing the glue cylinder groove and the limiting cover, the glue injection cylinder can be fixed, facilitating the glue injection operation of the glue injection cylinder. By aligning the glue injection hole with the needle tail outlet, the tail cylinder can be quickly aligned with the glue injection hole.
[0016] A further technical solution is that the driving mechanism includes a mounting seat fixedly arranged on the upper end of the bottom plate. The mounting seat is arranged on the right side of the moving clamping block. A sliding rod is fixedly arranged on the right side wall of the moving clamping block. The sliding rod slidably penetrates through the mounting seat. A screw rod is also screwed and penetrated through the mounting seat. The left end of the screw rod penetrates out of the mounting seat and is rotatably connected to the right side wall of the moving clamping block. The right end of the screw rod penetrates out of the mounting seat and is fixedly provided with a turning handle.
[0017] When using the above solution, by rotating the turning handle, the screw rod is driven to rotate. The screw rod realizes left-right movement by rotating in the mounting seat, thereby driving the moving clamping block to move left and right.
[0018] A further technical solution is that clamping grooves are oppositely arranged on the opposite side walls of the moving clamping block and the fixed clamping block respectively.
[0019] When using the above solution, when the needle-carrying slider abuts against the transverse baffle, the tail cylinder is exactly located between the clamping grooves. By moving the moving clamping block, the two clamping grooves gradually clamp and compress the tail cylinder.
[0020] A further technical solution is that the wire threading groove includes a semi-conical groove and a semi-cylindrical groove which are connected to each other. The semi-cylindrical groove is arranged at the front end of the semi-conical groove, and the front end of the semi-cylindrical groove communicates with the front side walls of the wire threading base and the wire threading cover. The smaller end of the semi-conical groove is connected to the semi-cylindrical groove, and the larger end of the semi-conical groove communicates with the rear side walls of the wire threading base and the wire threading cover. When the wire threading cover is closed on the wire threading base, the two semi-cylindrical grooves form a cylindrical groove, and the two semi-conical grooves form a conical groove.
[0021] A further technical solution is that the wire threading cover is also hinged to the wire threading base through a hinge.
[0022] When using the above solution, by setting the hinge to hinge the wire threading cover to the wire threading base, it is more convenient to open and close the wire threading cover.
[0023] A further technical solution is that a needle-carrying plate is also detachably installed at the upper end of the needle-carrying slider, and the needle groove is opened on the upper end surface of the needle-carrying plate. One end of the needle groove communicates with the rear side wall of the needle-carrying plate to form a needle tail outlet.
[0024] When using the above solution, by setting the needle-carrying plate, the needle-carrying plate provided with needle grooves of different models can be quickly replaced, which is convenient for the combination of suture needles of different models.
[0025] A further technical solution is that the convex block is made of a transparent or semi-transparent material.
[0026] When using the above solution, the convex block made of a transparent or semi-transparent material can more clearly see the flow of the glue in the glue injection hole.
[0027] A further technical solution is that the wire threading cover is made of a transparent or semi-transparent material.
[0028] When using the above solution, the wire threading cover made of a transparent or semi-transparent material can more clearly see the wire threading situation.
[0029] The beneficial effects of the present utility model are as follows:
[0030] 1. High-efficiency positioning: By setting the longitudinal baffle and the transverse baffle, the needle-carrying slider and the glue-carrying slider can be quickly positioned to the preset positions, which greatly improves the efficiency and accuracy of the glue injection and wire feeding operations.
[0031] 2. Convenient glue injection: In the solution, a movable glue-carrying slider is set and a glue injection mechanism is carried. This design makes the glue injection operation more convenient and flexible. By setting the glue cylinder groove and the limit cover to fix the glue injection cylinder, it is convenient to carry out the glue injection operation. At the same time, the alignment design of the glue injection hole and the needle tail outlet enables the tail cylinder to quickly align with the glue injection hole, simplifying the operation steps.
[0032] 3. Fast and accurate threading: The thread groove designed in the device includes a column groove and a conical groove. This structure enables the suture to be quickly and accurately fed into the tail cylinder of the suture needle and relatively fixed, providing convenience for the subsequent quick clamping and fixing of the fixed clamping block and the moving clamping block.
[0033] 4. Quick removal function: By setting an openable and closable thread cover, when the suture needle and the suture are combined, the suture needle and the suture can be quickly removed, improving work efficiency.
[0034] 5. Strong adaptability: By setting a needle carrier plate, users can quickly replace the needle carrier plates with different types of needle grooves. This design enhances the flexibility of the solution, facilitates adapting to different types of suture needles, and thus expands the application range of the device.
