Description

Technical Field

[0001] This utility model relates to the field of suture devices, and more specifically, to a suture device and a suture device for use in suture devices. Background Technology

[0002] Currently, most forming machines use a method where the sewing device is suspended from a light-guided beam track using an optical axis or other guiding structure. However, because the sewing device is suspended at a relatively high height, it sways significantly, posing the following safety hazards: 1. The sewing device is prone to colliding with the bonding template, causing damage to both the sewing device and the template; 2. Improper handling by operators when retrieving the sewing device can easily cause injury. Without a suspension device, operation becomes extremely laborious, and the sewing quality is significantly affected. Utility Model Content

[0003] The main objective of this invention is to provide a suturing device and a suturing machine for use in suturing machines, so as to solve the problem of safety hazards in existing suturing machines.

[0004] To achieve the above objectives, according to one aspect of the present invention, a suturing device for a suture device is provided, comprising a base, a suturing drive, a suture, and a positioning assembly. The suturing drive is connected to the base; the suturing drive is driven to the suture and drives the suture to rise and fall; the positioning assembly is connected to the base and is disposed between the suture and the suturing drive. When the suture rises, the positioning assembly drives the suture to rotate around its longitudinal axis to adjust the orientation of the suture.

[0005] Furthermore, the positioning component includes: a positioning block and a connecting frame. The positioning block is located at the bottom of the positioning component and has a downward-facing positioning notch at the bottom. The connecting frame is disposed at the top of the sewing piece, and the sewing drive is connected to the sewing piece through the connecting frame. The top of the connecting frame has a positioning protrusion that extends into the positioning notch and limits the orientation of the sewing piece.

[0006] Furthermore, the positioning protrusion is pyramidal, prismal, or cylindrical with its axis not parallel to the rotation axis of the sewing piece, so as to prevent rotational engagement between the positioning protrusion and the positioning notch.

[0007] Furthermore, the positioning block includes multiple sub-blocks, which are spaced apart to form positioning notches. When the positioning protrusion engages with the positioning notch to prevent rotation, the positioning protrusion simultaneously abuts against two oppositely positioned sub-blocks.

[0008] Furthermore, the sewing device also includes a cable, with its two ends connected to the sewing drive and the sewing piece, respectively. The sewing drive drives the sewing piece to move up and down via the cable.

[0009] Furthermore, the suturing device also includes a limiting component, which is connected to the base body and has a longitudinally extending limiting channel through which the cable passes.

[0010] Furthermore, the limiting component includes multiple limiting wheels, which are rotatably connected to the base, forming a limiting channel between the limiting wheels. When the cable is raised or lowered, it drives the limiting wheels to rotate.

[0011] Furthermore, the limiting wheel has a circumferentially extending groove, and the outer edges of the grooves of two opposing limiting wheels abut against each other, forming a limiting channel.

[0012] Furthermore, the stitcher also includes a steering element, which is rotatably connected to the base and is located on the movement path of the cable to change the direction of the cable's movement.

[0013] According to another aspect of the present invention, a suture device is provided, including the above-described suture device for a suture device.

[0014] By applying the technical solution of this utility model, on the one hand, by setting a positioning component to adjust the orientation of the sewing piece when it rises to a designated height, the sewing piece is positioned to avoid interference with other moving parts, thus preventing damage caused by interference between the sewing piece and the bonding template or other moving parts, thereby improving the safety of the sewing device. On the other hand, by setting a sewing drive component, the sewing piece can automatically descend to the working height when in use, and after use, the sewing piece is retracted by the sewing drive component to a height and orientation that avoids other moving parts, thereby preventing the sewing device from colliding with the operator due to improper operation, further improving the safety of the sewing device, and also reducing space occupation. In this way, when the sewing piece is not in use, it can automatically adjust to a safe height and orientation, and when in use, the sewing piece automatically descends, thereby avoiding safety hazards and reducing space occupation.

[0024] To address the safety hazards of existing suture devices, this invention provides a suturing device and a suture device, wherein the suture device includes the following suturing device.

[0025] like Figures 1 to 3 A suturing device for a suture device is shown, comprising a base 10, a suturing drive 20, a suture 30, and a positioning assembly 40. The suturing drive 20 is connected to the base 10; the suturing drive 20 is driven to connect with the suture 30 and drives the suture 30 to rise and fall; the positioning assembly 40 is connected to the base 10 and is disposed between the suture 30 and the suturing drive 20. When the suture 30 rises, the positioning assembly 40 drives the suture 30 to rotate around its longitudinal axis to adjust the orientation of the suture 30.

[0026] This embodiment, on the one hand, adjusts the orientation of the sewing piece 30 when it rises to a designated height by setting a positioning component 40, thereby ensuring that the sewing piece 30 is positioned to avoid interference with other moving parts, thus preventing damage caused by interference between the sewing piece 30 and other moving parts such as the bonding template, thereby improving the safety of the sewing device. On the other hand, it sets a sewing drive component 20 so that the sewing piece 30 can automatically descend to the working height when in use, and after use, the sewing piece 30 is retracted by the sewing drive component 20 to a height and orientation that avoids other moving parts, thereby preventing the sewing device from colliding with the operator due to improper operation, thus further improving the safety of the sewing device, while also reducing space occupation. In this way, when the sewing piece 30 is not in use, it can automatically adjust to a safe height and orientation, and when in use, the sewing piece 30 automatically descends, thereby avoiding safety hazards and reducing space occupation.

[0027] In this embodiment, the positioning component 40 includes a positioning block 41 and a connecting frame 42. The positioning block 41 is located at the bottom of the positioning component 40, and the bottom of the positioning block 41 has a downward-facing positioning notch. The connecting frame 42 is disposed at the top of the sewing piece 30, and the sewing drive member 20 is connected to the sewing piece 30 through the connecting frame 42. The top of the connecting frame 42 has a positioning protrusion that extends into the positioning notch and limits the orientation of the sewing piece 30. Specifically, as... Figure 2 As shown, the positioning block 41 in this embodiment is disposed on the periphery of the connecting frame 42, so that when the connecting frame 42 rises, the positioning protrusion abuts against the positioning block 41 located on its periphery, thereby limiting the direction of the connecting frame 42. In this way, through the cooperation of the positioning block 41 and the connecting frame 42, the placement direction of the sewing piece 30 can be precisely controlled, thereby adjusting the direction of the sewing piece 30 to the preset direction, thereby effectively avoiding other components.

[0028] In this embodiment, the positioning protrusion is pyramidal, prismal, or cylindrical with its axis not parallel to the rotation axis of the sewing piece 30. This design prevents rotational engagement between the positioning protrusion and the positioning notch. In other words, when the positioning protrusion is within the positioning notch, the surface of the positioning protrusion near the positioning block 41 is limited by the positioning block 41, thereby locking the orientation of the positioning protrusion and thus the placement direction of the sewing piece 30, achieving effective avoidance. Specifically, in this embodiment, the positioning protrusion is configured as a triangular ring structure and placed vertically, with its bottom close to the top of the sewing piece 30. This allows the positioning protrusion to abut against the positioning block 41 when it extends into the positioning notch, thereby locking the orientation of the sewing piece 30. Thus, as the sewing piece 30 rises, the positioning protrusion also rises synchronously, gradually extending into the notch. The positioning block 41 guides it until the positioning protrusion is fully embedded at a predetermined angle, thereby limiting the position of the sewing piece 30. Of course, the positioning protrusion can also be set as a vertically arranged ring or other structural form, which can cooperate with the positioning notch to prevent rotation, and at the same time reliably fix it with the sewing piece 30, thereby limiting the direction of the sewing piece 30.

[0029] In this embodiment, the positioning block 41 includes multiple sub-blocks, which are spaced apart and form positioning notches. When the positioning protrusion engages with the positioning notch to prevent rotation, the positioning protrusion simultaneously abuts against the two oppositely positioned sub-blocks, thereby restricting and adjusting the placement direction of the sewn piece 30. Specifically, this embodiment has two sub-blocks, which are configured as triangular prisms with the prisms placed vertically. The two faces of the two prisms that are close to each other are vertically opposite each other, thereby forming a parallelogram-shaped positioning notch at the bottom of the two prisms for the positioning protrusion to extend into, thus defining the position of the positioning protrusion.

[0030] Depending on actual usage requirements, the sub-blocks can also be configured as cuboids, cubes, or other structural forms, creating rectangular positioning notches at the bottom of the two sub-blocks to limit the stitching piece 30 in other directions. Compared to rectangular positioning notches, the inclination of parallelogram-shaped positioning notches depends on the actual angle at which the stitching piece 30 needs to be limited, effectively avoiding other moving parts. Of course, the shape of the positioning notch is not limited to the above forms and can be adjusted according to actual conditions. For example, the two adjacent surfaces of the two sub-blocks can be designed as wavy extensions, forming a wavy positioning notch between the two wavy surfaces, which can also achieve positioning of the positioning protrusion to limit the orientation of the stitching piece 30.

[0031] Preferably, a limiting rod is provided at the edge of the positioning notch. The limiting rod is placed horizontally, and the two ends of the limiting rod are close to the two oppositely arranged sub-blocks. This allows the connecting frame 42 to rise to a certain height and then abut against the limiting rod, thereby preventing the connecting frame 42 from rising further and limiting the sewing piece 30 to a suitable height, thus avoiding damage caused by excessive rising of the sewing piece 30 due to collision with other components.

[0032] In this embodiment, the suturing device further includes a cable 50, with both ends of the cable 50 connected to the suturing drive 20 and the suturing piece 30, respectively. The suturing drive 20 drives the suturing piece 30 to rise and fall via the cable 50, thereby simplifying the drive structure of the suturing piece 30 and making the suturing device more compact and lightweight, facilitating operation. Specifically, as... Figure 1 As shown, the first end of cable 50 is connected to the sewing drive 20, and the second end is connected to the sewing piece 30 via the connecting bracket 42. The height of the first end is higher than the height of the second end, meaning the height of the sewing drive 20 is higher than the height of the sewing piece 30. This allows the sewing drive 20 to always be positioned to avoid other components. Furthermore, the sewing piece 30 can be manipulated by raising and lowering cable 50. Compared to a rigid connection, the cable 50 connection allows the operator to make slight adjustments to the height of the sewing piece 30, improving the flexibility and adaptability of the sewing device. Optionally, cable 50 can be made of steel wire rope.

[0033] In this embodiment, the sewing device also includes a limiting component 60, which is connected to the base 10. The limiting component 60 has a longitudinally extending limiting channel, through which the cable 50 passes. Thus, when the cable 50 moves the sewing piece 30 up and down, the limiting channel prevents unnecessary swaying or twisting of the cable 50 during movement, reducing the amplitude of the swaying of the sewing piece 30 and ensuring the safety of the sewing piece 30 and the operator, preventing damage to the equipment and injury to the operator. Furthermore, the limiting component 60 ensures the stability of the cable 50 along its movement path, reducing the frequency of cable maintenance and replacement, and lowering the operating cost of the equipment. In this embodiment, the limiting component 60 is located above the positioning component 40. That is, the cable 50 first passes through the initial limiting component 60 from top to bottom to prevent significant swaying of the sewing piece 30, and then undergoes precise positioning by the positioning component 40 to limit the orientation of the sewing piece 30, thereby improving the stability and accuracy of the sewing piece 30 during placement.

[0034] In this embodiment, the limiting component 60 includes multiple limiting wheels 61, which are rotatably connected to the base 10. A limiting channel is formed between the limiting wheels 61. When the cable 50 rises or falls, it drives the limiting wheels 61 to rotate, thereby limiting the cable 50 while reducing friction, which helps extend the service life of the cable 50. Specifically, this embodiment includes two limiting wheels 61, which are placed vertically and arranged horizontally. The cable 50 is located between the outer circumferential surfaces of the two limiting wheels 61. This allows the limiting wheels 61 to limit the position of the cable 50, and also allows them to rotate with the rise and fall of the cable 50, thereby reducing the friction between the cable 50 and the limiting component 60. Of course, the limiting component 60 can also be configured as a circular sleeve or similar structure fixed below the suspension beam, as long as it can limit the cable 50. The limiting wheels 61 can also be four, six, or more, arranged in groups of two along the extension direction of the cable 50, thereby further improving the limiting effect on the cable 50.

[0035] In this embodiment, the limiting wheel 61 has a circumferentially extending groove 611. The outer edges of the grooves 611 of two opposing limiting wheels 61 abut against each other, forming a limiting channel. The design of the groove 611 makes the cable 50 move more smoothly within the limiting channel, while reducing wear on the cable 50, extending its service life, and reducing production costs. Specifically, as... Figure 3 As shown, the outer peripheral surface of the limiting wheel 61 in this embodiment is an arc-shaped surface that is concave towards the center of the limiting wheel 61, thereby forming a wheel groove 611 extending circumferentially along the limiting wheel 61. When the two limiting wheels 61 are placed side by side, a limiting channel is formed between the two wheel grooves 611, thereby limiting the cable 50 and improving the stability and safety of the sewing piece 30 during the lifting process.

[0036] In this embodiment, the stitcher also includes a steering component 70, which is rotatably connected to the base 10. The steering component 70 is located on the movement path of the cable 50 to change the movement direction of the cable 50. Thus, the steering component 70 changes the extension direction of the cable 50 from horizontal to vertical, thereby satisfying both the horizontal placement of the stitching drive 20 above the stitching piece 30 and the vertical lifting of the stitching piece 30. In this embodiment, the steering component 70 is configured as a steering wheel, similar in structure to the limiting wheel 61. The steering wheel is positioned above the limiting wheel 61, and the cable 50 is disposed within the groove of the steering wheel, thereby enabling the steering wheel to steer and reduce friction during the movement of the cable 50.

[0037] It should be noted that "multiple" in the above embodiments refers to at least two.

[0038] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0039] 1. This technology solves the safety hazards associated with existing suture devices;

[0040] 2. By setting a positioning component to adjust the orientation of the sewing piece when it rises to a specified height, the sewing piece can be positioned to avoid interference with other moving parts, thereby preventing damage caused by interference between the sewing piece and other moving parts such as the bonding template, thus improving the safety of the sewing device;

[0041] 3. A sewing drive mechanism is installed so that the sewing piece can automatically descend to the working height when in use, and after use, the sewing piece is retracted by the sewing drive mechanism to a height and orientation that avoids other moving parts. This prevents the sewing device from colliding with the operator due to improper operation when the operator picks it up, thereby further improving the safety of the sewing device and reducing the space occupation.
