Description

Technical Field

[0001] This utility model relates to the field of wire cutting equipment technology, specifically to a high-efficiency cutting device for the production of medical spring hoses for minimally invasive surgery. Background Technology

[0002] Minimally invasive surgical spring tubing is a delivery channel used to insert endoscopic instruments such as biopsy forceps and hemostatic forceps into a designated surgical site within the patient's body. Minimally invasive surgical spring tubing typically consists of a metal spring tube and a polymer sheath covering the outer periphery of the metal spring tube. The manufacturing process involves cutting the metal spring tube to a predetermined length and then covering the outer periphery of the cut metal spring tube with a polymer sheath.

[0003] Currently, in the production and processing of minimally invasive surgical medical spring tubes, the metal spring tubes are still mechanically cut using hard cutting equipment such as grinding wheels and pliers. This cutting method has the following defects: (1) The cut end face of the metal spring tube is not smooth, and there are often burrs on the cut end face. If these burrs are not removed, the processed minimally invasive surgical medical spring tubes may scratch the outer sheath of the endoscope during subsequent assembly and use, and may even affect the smoothness of the endoscope instruments entering and exiting inside. Therefore, an additional polishing process is required to polish the cut end of the metal spring tube; (2) The metal spring tubes are mostly cut using a single-end cutting method, that is, after cutting one end, the operator needs to rotate the spring tube 180° to cut the other end. This process is cumbersome, time-consuming, and labor-intensive, resulting in low efficiency in the overall production and processing of metal spring tubes, making it difficult to meet the demand for large-volume delivery. This utility model proposes an efficient cutting device for the production of minimally invasive surgical medical spring tubes in order to solve the above technical problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a high-efficiency cutting device for the production of medical spring tubes for minimally invasive surgery. In use, the main body of the metal spring tube is placed on the lifting and positioning assembly, and the left end of the metal spring tube to be cut is fixedly clamped to the positioning and pressing assembly. The controller drives the Y-axis moving module one to move the positioning and pressing assembly towards the electrode wire side. Simultaneously, the lifting and positioning assembly, through the Y-axis moving module two, moves the main body of the metal spring tube towards the electrode wire side, achieving vertical discharge cutting of the left end of the metal spring tube by the electrode wire. Then, by rotating the support 1 180° horizontally, the metal spring tube is turned around. Then, the other end of the metal spring tube to be cut, located on the left side, is fixed and clamped onto the positioning and clamping assembly. The above operation is repeated to achieve discharge cutting of the other end of the metal spring tube. The end of the metal spring tube cut by the electrode wire discharge has good flatness and no burrs, and no subsequent polishing is required. The support can flip relative to the support platform in the vertical plane to form a seesaw structure, which makes it easier for the left end of the metal spring tube to be released upward from the positioning and clamping assembly after cutting. This reduces the difficulty of operation when the metal spring tube is rotated horizontally by 180°, greatly simplifies the amount of manual labor, significantly improves the overall cutting efficiency of the end of the metal spring tube, meets the needs of large-volume delivery, and is economical and practical.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a high-efficiency cutting device for the production of medical spring tubes for minimally invasive surgery, including a workbench one and a workbench two. An electrode wire support frame is fixedly provided on the rear side of the upper end face of the workbench one. An electrode wire is provided at the front end of the electrode wire support frame in the longitudinal direction. A positioning and clamping assembly for fixing and clamping the left end of the metal spring tube is provided on the front side of the upper end face of the workbench one. A Y-axis moving module one for driving the positioning and clamping assembly to move along the horizontal Y-axis and an X-axis moving module one for driving the positioning and clamping assembly to move along the horizontal X-axis are also provided on the front side of the upper end face of the workbench one. The electrode wire and the Y-axis moving module one are both connected to a controller.

[0006] The second workbench is located to the right of the first workbench. The upper surface of the second workbench is provided with a support platform, a Y-axis moving module two for moving the support platform along the horizontal Y-axis, and an X-axis moving module two for moving the support platform along the horizontal X-axis. The upper surface of the support platform is equipped with a support seat that can rotate in the horizontal direction, and the upper end of the support seat is equipped with a support base one that can flip in the vertical plane. The upper surface of the support base one can also be detachably equipped with a lifting and positioning component for supporting the main body of the metal spring tube.

[0007] This invention discloses a high-efficiency cutting device for the production of medical spring tubes for minimally invasive surgery. In use, the main body of the metal spring tube is placed on a lifting and positioning assembly, and the left end of the metal spring tube to be cut is fixedly clamped to a positioning and pressing assembly. A controller drives a Y-axis moving module one to move the positioning and pressing assembly towards the electrode wire. Simultaneously, the lifting and positioning assembly, via a Y-axis moving module two, moves the main body of the metal spring tube towards the electrode wire, achieving vertical discharge cutting of the left end of the metal spring tube by the electrode wire. Then, by rotating the support 1 180° horizontally, the metal spring tube is turned around, and the metal spring tube is then positioned... The other end to be cut on the left is fixedly clamped onto the positioning and clamping assembly. The above operation is repeated to achieve discharge cutting of the other end of the metal spring tube. The end of the metal spring tube cut by the electrode wire has good flatness and no burrs, and no subsequent polishing is required. The support can flip relative to the support platform in the vertical plane to form a seesaw structure, which makes it easier for the left end of the metal spring tube to be released upward from the positioning and clamping assembly after cutting. This reduces the difficulty of operation when the metal spring tube is rotated horizontally by 180°, greatly simplifies the amount of manual labor, significantly improves the overall cutting efficiency of the end of the metal spring tube, meets the needs of large-volume delivery, and is economical and practical.

[0008] The preferred technical solution is that the positioning and pressing assembly includes a support plate, a positioning seat and a pressure plate. The positioning seat is fixed to the top of the support plate and has a V-shaped groove that passes through the left and right end faces and opens upward. The pressure plate is correspondingly overlapped and laid on the upper end faces of the two side walls of the V-shaped groove. The two ends of the pressure plate are fixedly locked together with the upper end faces of the two side walls of the V-shaped groove through a detachable locking assembly.

[0009] The lifting and positioning assembly includes a second support with a "V"-shaped cross-section. The second support has an upward-opening V-shaped groove inside, and the first support has a V-shaped positioning groove that extends through both its left and right ends and opens upward. The second support is fitted into the V-shaped positioning groove on the first support. In use, the main body of several metal spring tubes is loaded into the V-shaped groove on the second support, and the left ends of the several metal spring tubes are pressed and fixed into the V-shaped groove on the positioning seat by a pressure plate. This causes the several metal spring tubes to naturally gather and tighten together due to their own friction and weight, driven by the inclination angle of the inner walls of the V-shaped groove and the first V-shaped groove. This prevents the left ends of the several metal spring tubes from shifting during the cutting process, which helps to improve cutting quality and efficiency.

[0010] A further preferred technical solution is that the support is an upward-opening channel steel, and several stiffening plates are vertically fixed at intervals along the length direction on the front and rear side walls inside the support. Each of the stiffening plates has an upward-opening V-shaped groove in the middle, and the V-shaped grooves on the stiffening plates form the V-shaped positioning groove.

[0011] The second support has horizontal skirts extending outwards at the upper ends of both its front and rear sides. When the second support is fitted into the V-shaped positioning groove on the first support, the horizontal skirt on the front side extends to the outside of the front edge of the first support, and the horizontal skirt on the rear side extends to the outside of the rear edge of the first support. The bottom of the first support has a flat structure, which facilitates flipping and installation on the upper end of the support base. The ribs fixed inside the first support reinforce the support body, and the V-shaped grooves on the ribs form a V-shaped positioning groove that fits the second support well. The structural design is ingenious and reasonable, and the manufacturing and implementation are highly feasible. The horizontal skirts at the upper ends of the front and rear sides of the second support improve the convenience of lifting or hoisting the second support, and effectively prevent the second support from being stuck by the V-shaped positioning groove on the first support.

[0012] A further preferred technical solution includes a plurality of pressure plates II spaced along the length of the upper end of the support II, located in the Y-axis direction. The two ends of each pressure plate II overlap the horizontal skirts on the front and rear sides of the support II, and the ends of the pressure plates II are fixedly locked to the corresponding horizontal skirts via detachable locking components II. When the metal spring tubes are loaded inside the support II, the pressure plates II exert a pressing and restraining effect on the metal spring tubes, thereby effectively preventing the metal spring tubes from slipping during loading or unloading of materials onto the support II, and improving operational safety during loading or unloading.

[0013] A further preferred technical solution is that the detachable locking assembly includes mounting holes formed at both ends of the pressure plate and on the upper surfaces of both sides of the V-groove, as well as screws that pass through the corresponding mounting holes.

[0014] The second detachable locking assembly includes mounting holes on the horizontal skirts at both ends of the pressure plate and on the front and rear sides of the support, as well as screws that pass through the corresponding mounting holes. Both the first and second detachable locking assemblies have a simple structural design, are easy to install or disassemble, and are highly practical.

[0015] A further preferred technical solution is that the upper surface of the workbench is provided with a Y-axis moving module, and the X-axis moving module is installed on the moving module at the upper end of the Y-axis moving module. The top of the moving module at the upper end of the X-axis moving module is fixedly provided with two "n"-shaped brackets located at the left and right ends, and the two "n"-shaped brackets are arranged along the horizontal Y-axis direction. The top of the two "n"-shaped brackets is fixedly provided with two support beams located at the front and rear ends, and the two support beams are arranged along the horizontal X-axis direction. The support plate is overlapped and fixedly provided at the top right end of the two support beams along the horizontal Y-axis direction.

[0016] The electrode wire support frame includes a column fixed to the rear edge of the upper surface of a workbench. A second support arm, extending horizontally forward between two "n"-shaped supports, is fixed to the lower end of the column. A third support arm, capable of lifting and extending horizontally forward above two support beams, is correspondingly installed on the upper end of the column. The electrode wire is mounted on the front ends of both the first and second support arms. The ingenious structural design and reasonable layout, along with the good correspondence between the electrode wire and the positioning and clamping components, ensure the smooth fabrication and implementation of the cutting device of this invention.

[0017] A further preferred technical solution includes a second workbench fixed to the right side wall of the first workbench. The second Y-axis moving module includes a slide rail fixed to the top of the second workbench along the Y-axis and a support plate slidably mounted on the top of the slide rail. The second X-axis moving module includes a slide rail fixed to the top of the support plate 2 along the X-axis and a support plate slidably mounted on the top of the slide rail. The support platform is fixed to the top of the support plate 3. The second workbench, fixed to the right side wall of the first workbench, offers good overall compactness. The rational layout of the second X-axis moving module and the second Y-axis moving module ensures good synchronization between the support plate 2 mounted on the support platform and the first Y-axis moving module during cutting operations, thereby ensuring good consistency in the length of the cut metal spring tubes.

[0018] A further preferred technical solution is that the support base includes a support base one and a support base two. The support base one is horizontally rotatably mounted on the top of the support platform, and the support base two is fixedly mounted on the lower side of the support base one. The upper end of the support base one and the lower end of the support base two are rotatably connected together by a rotating connecting assembly, and the support base two can be rotated relative to the support base one in the vertical plane. The support base structure is ingeniously and reasonably designed, ensuring the smooth fabrication and implementation of the cutting device of this utility model.

[0019] A further preferred technical solution is that the support base includes a base plate, and a set of lug plates are vertically fixed on the front and rear sides of the upper end of the base plate. The lug plates have pin holes that penetrate the plate body. The base plate is horizontally rotatably mounted on the top of the support platform through a rotating shaft assembly.

[0020] The second support base and the first support base are symmetrically structured. The base plate of the second support base is fixed to the center of the lower side of the first support base. A set of lugs on the first support base and a set of lugs on the second support base are inserted and connected by a rotating shaft passing through a pin hole. The lugs on the first support base and the second support base, along with the rotating shaft passing through the pin hole, constitute the rotating connection assembly. The base plate of the first support base is horizontally mounted on the top of the support platform via the rotating shaft assembly. The lugs on the first support base and the second support base are inserted and connected by a rotating shaft passing through a pin hole, ensuring good stability of the rotating connection between the first and second support bases and achieving dual rotation functions of horizontal rotation and longitudinal flipping. This further ensures the successful fabrication and implementation of the cutting device of this invention.

[0021] A further preferred technical solution is that the left end of the base plate on support one and the left end of the base plate on support two are connected together by a buffer spring, and the right end of the base plate on support one and the right end of the base plate on support two are connected together by another buffer spring. After one end of the metal spring tube is cut, when support one and support two, which contain the metal spring tube, are rotated 180° horizontally to turn around, they are pushed to the right a certain distance by the X-axis moving module two. This also allows the left end of the metal spring tube to be lifted up and disengaged from the positioning and clamping assembly. At this time, the buffer spring plays a buffering role, effectively preventing one end of support one and support two from violently lifting up and causing a safety accident, thus helping to improve the safety of use.

[0022] The advantages and beneficial effects of this utility model are as follows:

[0023] 1. This utility model discloses a high-efficiency cutting device for the production of medical spring tubes for minimally invasive surgery. In use, the main body of the metal spring tube is placed on a lifting and positioning assembly, and the left end of the metal spring tube to be cut is fixedly clamped onto a positioning and pressing assembly. A controller drives a Y-axis moving module one to move the positioning and pressing assembly towards the electrode wire side. Simultaneously, the lifting and positioning assembly, through a Y-axis moving module two, moves the main body of the metal spring tube towards the electrode wire side, achieving vertical discharge cutting of the left end of the metal spring tube by the electrode wire. Then, by rotating the support 1 180° horizontally, the metal spring tube is turned around, and the metal spring tube is then positioned... The other end to be cut on the left is fixedly clamped onto the positioning and clamping assembly. The above operation is repeated to achieve discharge cutting of the other end of the metal spring tube. The end of the metal spring tube cut by the electrode wire has good flatness and no burrs, and no subsequent polishing is required. The support can flip relative to the support platform in the vertical plane to form a seesaw structure, which makes it easier for the left end of the metal spring tube to be released upward from the positioning and clamping assembly after cutting. This reduces the difficulty of operation when the metal spring tube is rotated horizontally by 180°, greatly simplifies the amount of manual labor, significantly improves the overall cutting efficiency of the end of the metal spring tube, meets the needs of large-volume delivery, and is economical and practical.

[0024] 2. In use, the main body of several metal spring tubes is loaded into the V-shaped through groove on the support 2, and the left end of several metal spring tubes is pressed and fixed into the V-shaped groove 1 on the positioning seat by the pressure plate 1. Under the inclination angle of the inner wall surfaces on both sides of the V-shaped through groove and the V-shaped groove 1, the several metal spring tubes naturally gather and tighten together by their own friction and weight, so that the left end of several metal spring tubes will not shift during the cutting process, which helps to improve the cutting quality and cutting efficiency.

[0025] 3. The bottom of the support is a flat structure, which makes it easy to flip and install on the upper part of the support base. The stiffening plate fixed inside the support reinforces the support body. At the same time, the V-shaped groove on the stiffening plate forms a V-shaped positioning groove that is well adapted to the support. The structural design is ingenious and reasonable, and the manufacturing and implementation are highly feasible. The horizontal skirts on the upper ends of the front and rear sides of the support improve the convenience of lifting or hoisting the support and effectively prevent the support from being stuck by the V-shaped positioning groove on the support.

[0026] 4. The upper end of the support bracket two is provided with several pressure plates two located along the Y-axis direction at intervals along its length. The two ends of the pressure plates two overlap the horizontal skirts on the front and rear sides of the support bracket two, and the ends of the pressure plates two are fixedly locked to the corresponding horizontal skirts by a detachable locking assembly two. When several metal spring tubes are loaded inside the support bracket two, the pressure plates two exert a pressing and binding effect on the metal spring tubes, thereby effectively preventing the metal spring tubes from slipping when loading or unloading materials from the support bracket two, and improving the operational safety during loading or unloading.

[0027] 5. The second workbench is fixed to the right side wall of the first workbench. The second Y-axis moving module includes a slide rail fixed to the top of the second workbench along the Y-axis and a support plate 2 slidably mounted on the top of the slide rail. The second X-axis moving module includes a slide rail 2 fixed to the top of the support plate 2 along the X-axis and a support plate 3 slidably mounted on the top of the slide rail. The support platform is fixed to the top of the support plate 3. The second workbench is fixed to the right side wall of the first workbench, resulting in good overall compactness. The second X-axis moving module and the second Y-axis moving module are rationally arranged, ensuring good synchronization between the support plate 2 mounted on the support platform and the first Y-axis moving module during cutting operations, thereby ensuring good consistency in the length of the cut metal spring tubes.

[0028] 6. The left ends of the base plates on support one and support two are connected by a buffer spring, and the right ends of the base plates on support one and support two are connected by another buffer spring. After one end of the metal spring tube is cut, when support one and support two, which contain the metal spring tube, are rotated 180° horizontally to turn around, they are pushed to the right a certain distance by the X-axis moving module two. This also allows the left end of the metal spring tube to be lifted up and disengaged from the positioning and clamping assembly. At this time, the buffer spring acts as a buffer, effectively preventing one end of support one and support two from violently lifting up and causing a safety accident, thus improving the safety of use.

[0054] More preferably, the left end of the base plate 11-1 on the first support 11 and the left end of the base plate on the second support 12 are connected together by a buffer spring 11-3, and the right end of the base plate 11-1 on the first support 11 and the right end of the base plate on the second support 12 are connected together by another buffer spring 11-3.

[0055] Specifically, the side of the pressure plate 7-3 and the pressure plate 14-3 facing the metal spring tube is provided with a flexible material layer, which effectively prevents the pressure plate 7-3 and the pressure plate 14-3 from causing hard pressure damage or deformation to the metal spring tube.

[0056] The working principle of this utility model for a high-efficiency cutting device used in the production of minimally invasive surgical medical spring hoses is as follows:

[0057] Step 1: Adjust the Y-axis moving module 5 and the X-axis moving module 6 through the controller so that the left end face of the positioning and clamping component 7 is at a suitable distance from the electrode wire 4, and the electrode wire 4 is located at one end of the Y-axis moving module 5.

[0058] Step 2: In the initial state, both the pressure plate 7-3 on the positioning and clamping assembly 7 and the pressure plate 14-3 on the support 14 are in a disassembled state. Place the support 14 on the support of the loading platform, with the opening of the V-shaped groove 14-1 facing upwards. Fill the V-shaped groove 14-1 with several metal spring tubes 16, and adjust the distance between the two ends of the metal spring tubes 16 protruding from the outside of the V-shaped groove 14-1 to be approximately equal. Then, place the pressure plates 14-3 between them... The overlapping joint is laid on the upper end surface of the V-shaped through groove 14-1, so that the front end of the pressure plate 14-3 and the horizontal skirt 14-2 located on the front side of the support 14 are locked together by screws passing through the corresponding mounting holes of the two. Similarly, the rear end of the pressure plate 14-3 and the horizontal skirt 14-2 located on the rear side of the support 14 are locked together by screws passing through the corresponding mounting holes of the two. The support 14 with the metal spring tube 16 is hoisted onto the support 13.

[0059] Step 3: Insert one end of several metal spring tubes 16 on the left side into the V-groove 7-2a on the positioning seat 7-2. Adjust the position of the support 13 on the upper surface of the worktable 3 using the Y-axis moving module 9 and the X-axis moving module 10, so that the left end of several metal spring tubes 16 protrudes appropriately beyond the left end face of the positioning and clamping assembly 7, and the support 14 is positioned horizontally along the X-axis. Re-fix the pressure plate 7-3 to the upper surface of the positioning seat 7-2 with screws, thereby pressing and fixing the left end of several metal spring tubes 16 onto the positioning and clamping assembly 7 (see Appendix). Figure 6 and attached Figure 7 );

[0060] Step 4: Start the forward cutting button through the controller. The electrode wire 4 starts cutting. At the same time, the bidirectional drive motor on the Y-axis moving module 5 rotates in one direction and drives the X-axis moving module 6 and the positioning and clamping assembly 7 to move closer to the electrode wire 4. Meanwhile, the support 14 drags the main body of several metal spring tubes 16 through the Y-axis moving module 9 and moves synchronously with the positioning and clamping assembly 7 to move closer to the electrode wire 4 to complete the discharge cutting of several metal spring tubes 16 located on the left side. After cutting is completed, turn off the forward cutting button.

[0061] Step 5: Remove the pressure plate 7-3 from the upper end of the positioning seat 7-2. Push the support 13 to the right along the X-direction moving module 10 a certain distance. You can also tilt the left end of the support 13 upward a certain distance so that the left end of the metal spring tubes 16 is disengaged from the positioning clamping assembly 7 a certain distance. Then rotate the support 11, support 2 12, support 13, support 2 14, and the metal spring tubes 16 horizontally 180° and turn them around. Repeat step 3 so that the other end of the metal spring tubes 16 on the left side is pressed and fixed on the positioning clamping assembly 7.

[0062] Step 6: Start the reverse cutting button through the controller. The electrode wire 4 starts cutting. At the same time, the bidirectional drive motor on the Y-axis moving module 15 rotates in the other direction and drives the X-axis moving module 16 and the positioning and clamping assembly 7 to move closer to the electrode wire 4. Meanwhile, the support 2 14 drags the main body of several metal spring tubes 16 through the Y-axis moving module 2 9 and moves synchronously with the positioning and clamping assembly 7 to move closer to the electrode wire 4 to complete the discharge cutting of several metal spring tubes 16 located at the other end on the left. After cutting is completed, turn off the reverse cutting button.

[0063] Step 7: Remove the pressure plate 7-3 from the upper end of the positioning seat 7-2 again, and lift the support 14, which is loaded with the cut metal spring tube 16, from the support 13 to the unloading platform for subsequent unloading operations, thus completing a complete cutting cycle of several metal spring tubes 16.

[0064] This invention discloses a high-efficiency cutting device for the production of medical spring tubes for minimally invasive surgery. In use, the main body of the metal spring tube is placed on a lifting and positioning assembly, and the left end of the metal spring tube to be cut is fixedly clamped to a positioning and pressing assembly. A controller drives a Y-axis moving module one to move the positioning and pressing assembly towards the electrode wire. Simultaneously, the lifting and positioning assembly, via a Y-axis moving module two, moves the main body of the metal spring tube towards the electrode wire, achieving vertical discharge cutting of the left end of the metal spring tube by the electrode wire. Then, by rotating the support 1 180° horizontally, the metal spring tube is turned around, and the metal spring tube is then positioned... The other end to be cut on the left is fixedly clamped onto the positioning and clamping assembly. The above operation is repeated to achieve discharge cutting of the other end of the metal spring tube. The end of the metal spring tube cut by the electrode wire has good flatness and no burrs, and no subsequent polishing is required. The support can flip relative to the support platform in the vertical plane to form a seesaw structure, which makes it easier for the left end of the metal spring tube to be released upward from the positioning and clamping assembly after cutting. This reduces the difficulty of operation when the metal spring tube is rotated horizontally by 180°, greatly simplifies the amount of manual labor, significantly improves the overall cutting efficiency of the end of the metal spring tube, meets the needs of large-volume delivery, and is economical and practical.

[0065] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
