Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a suture adhesive applicator. Background Technology

[0002] In the prior art, medical sutures refer to special medical sutures used in surgical procedures for ligation and hemostasis, suturing for hemostasis, and tissue closure. Due to their good biocompatibility, sutures can be made into various medical implants and anchors. When used as anchors, they require a certain degree of rigidity; therefore, adhesive must be applied to the surface of the suture, and after the adhesive has cured, it is cut to form the anchor.

[0003] Currently, in the suture adhesive application process, sutures are mainly cured manually. Specifically, the suture is held at both ends with tweezers for fixation, and then an adhesive applicator is used to apply adhesive to the suture surface. After application, it is left to cure naturally. However, in practice, uneven adhesive application often occurs, resulting in low efficiency. Furthermore, the hardening effect of the suture after application is often unsatisfactory, with the suture prone to fraying, affecting its anchoring effect. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a suture adhesive application device to solve technical problems such as uneven adhesive application and unsatisfactory hardening effect of sutures.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A suture adhesive applicator includes a suture fixture, a suture tensioning assembly, and an adhesive dispensing module. The suture fixture is used to limit the end of the suture to be adhesiveped, and the suture tensioning assembly adjusts the tension of the suture.

[0006] The dispensing module includes a dispensing assembly, a glue cartridge, and a displacement drive assembly. The dispensing assembly includes a dispensing pen, a peristaltic tube, an adjusting bracket, and a peristaltic pump. The dispensing pen is mounted on the moving end of the displacement drive assembly via the adjusting bracket and can reciprocate under the drive of the displacement drive assembly. One end of the peristaltic tube passes through the dispensing pen and is fixedly connected to it; the other end is inserted into the glue cartridge. The middle portion of the peristaltic tube is loaded in the drive end of the peristaltic pump.

[0007] Furthermore, the suture tooling includes two spaced-apart support plates. Each support plate has a limiting hole that mates with the suture to be coated. Each suture to be coated passes through the corresponding limiting hole.

[0008] Furthermore, the suture tensioning assembly includes a clamp and a weight. The clamp is fixed to the top of the weight and is used to hold the end of the suture being coated with adhesive during use. The weight is used to tension the suture being coated with adhesive.

[0009] Furthermore, the port of the peristaltic tube is cut with a forked opening of 2-10mm.

[0010] Furthermore, the peristaltic tube is made of Teflon material.

[0011] Furthermore, the adjustment bracket includes a vertically fixed frame and a lifting frame, and a horizontally movable frame and an adjustment frame; the lifting frame is slidably connected to the fixed frame and can rise or fall vertically. The movable frame is slidably connected to the top of the lifting frame and can slide freely horizontally. The angle adjustment frame is rotatably connected to the outer end of the movable frame for adjusting the angle of the dispensing pen.

[0012] Furthermore, the displacement drive assembly includes a guide rail, a moving platform, a drive motor, and a motor controller. The moving platform is slidably connected to the guide rail and can reciprocate under the drive of the drive motor. The motor controller is used to control the rotation direction of the output shaft in the drive motor, thereby controlling the movement direction of the moving platform.

[0013] Furthermore, two limit sensors are spaced apart on the guide rail.

[0014] Furthermore, the displacement drive component also includes a timer. The timer is integrated into the motor controller.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This utility model achieves quantitative output of glue by setting a peristaltic tube and a peristaltic pump. The glued suture is limited and clamped by the suture tooling to achieve consistent suture tension. At the same time, the peristaltic tube is set on the moving end of the displacement drive component to achieve uniform application of glue output by the peristaltic tube to the glued suture, thereby improving processing efficiency while ensuring glue application quality.

[0016] 2. This utility model involves cutting a fork opening at the end of the peristaltic tube. This allows the suture to be coated with adhesive to be secured in the fork opening during use, thereby preventing the peristaltic tube from separating from the suture and ensuring the quality of the adhesive coating.

[0017] 3. This utility model can ensure the accuracy of the glue application length of the suture by linking the limit sensor with the dispensing component; the linkage between the timer and the dispensing component can ensure the consistency of the glue curing time. Attached Figure Description

[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, a suture adhesive application device includes a suture fixing module and an adhesive dispensing module. The suture fixing module includes a base 1, a suture fixture 2 and a suture tensioning assembly 3 mounted on the base 1. The suture fixture 2 is used to limit the end of the suture to be adhesiveped, and the suture tensioning assembly 3 adjusts the tension of the suture. The adhesive dispensing module is used to apply adhesive to the tensioned suture.

[0023] like Figure 1 and 2 As shown, the suture tool 2 includes two spaced-apart support plates 2-1. Each support plate 2-1 has a limiting hole that matches the suture to be coated. Each suture to be coated passes through the corresponding limiting hole and is tensioned by the suture tensioning assembly 3.

[0024] In this embodiment, the suture tensioning assembly 3 includes a clamp 3-1 and a weight 3-2. The clamp 3-1 is fixed to the top of the weight 3-2 and is used to clamp the end of the suture to be coated with adhesive during use. The weight of the weight 3-2 is used to tension the suture.

[0025] Furthermore, both support plates 2-1 are equipped with multiple limiting clamps 2-2. Each limiting clamp 2-2 corresponds to a limiting hole on the support plate 2-1, and its bottom is threaded into the support plate 2-1. After the weight 3-2 has completed the tensioning of the glued seam, the limiting clamp 2-2 can be rotated to press and fix the end of the glued seam, and can also prevent the weight 3-2 from moving due to the vibration of the glue dispensing module during the glue application process.

[0026] like Figure 1 and 3 As shown, the dispensing module includes a dispensing assembly 4, a glue cartridge 5, and a displacement drive assembly 6. The dispensing assembly 4 includes a dispensing pen 4-1, a peristaltic tube 4-2, an adjusting bracket 4-3, and a peristaltic pump 4-4. The dispensing pen 4-1 is mounted on the moving end of the displacement drive assembly 6 via the adjusting bracket 4-3, allowing it to reciprocate under the drive of the displacement drive assembly 6. One end of the peristaltic tube 4-2 passes through the dispensing pen 4-1 and is fixedly connected to it; the other end is inserted into the glue cartridge 5. The middle portion of the peristaltic tube 4-2 is mounted in the drive end of the peristaltic pump 4-4, enabling it to continuously output glue from the glue cartridge 5 through the peristaltic tube 4-2 under the drive of the peristaltic pump 4-4, thus cooperating with the displacement drive assembly 6 to complete the glue application operation on the seam.

[0027] In this embodiment, the peristaltic pump 4-4 is equipped with a pump body operation panel for operating and controlling the dispensing parameters of the peristaltic pump 4-4, such as the dispensing speed, so as to adapt to different dispensing needs.

[0028] In this embodiment, the peristaltic tube 4-2 is made of Teflon.

[0029] Furthermore, such as Figure 4 As shown, the port of the peristaltic tube 4-2 has a forked opening of 2-10mm. In use, the suture to be coated is inserted into the forked opening of the peristaltic tube 4-2 to prevent the peristaltic tube 4-2 from separating from the suture.

[0030] like Figure 3 and 5As shown, the adjusting bracket 4-3 includes a vertically oriented fixed bracket 4-3-1 and a lifting bracket 4-3-2, and a horizontally oriented movable bracket 4-3-3 and an angle adjusting bracket 4-3-4. The lifting bracket 4-3-2 is slidably connected to the fixed bracket 4-3-1 and can rise or fall vertically. The movable bracket 4-3-3 is slidably connected to the top of the lifting bracket 4-3-2 and can slide freely horizontally. The angle adjusting bracket 4-3-4 is rotatably connected to the outer end of the movable bracket 4-3-3 and is used to adjust the angle of the dispensing pen 4-1.

[0031] Specifically, the lifting frame 4-3-2 has a vertical first sliding groove. A through-hole height locking screw 4-3-5 is installed in the first sliding groove, allowing the lifting frame 4-3-2 to be locked in position by tightening the height locking screw 4-3-5 after it slides to a designated position. The moving frame 4-3-3 has a horizontal second sliding groove. A through-hole horizontal locking screw 4-3-6 is installed in the second sliding groove, allowing the moving frame 4-3-3 to be locked in position by tightening the horizontal locking screw 4-3-6 after it moves outward or inward to a designated position. The angle adjustment frame 4-3-4 is equipped with an angle locking screw. The outer end of the moving frame 4-3-3 has a clearance through-hole that mates with the angle locking screw. The angle locking screw passes through the clearance through-hole and is threaded into the angle adjustment frame 4-3-4, allowing the angle adjustment of the angle adjustment frame 4-3-4 to be locked or unlocked by loosening or tightening the angle locking screw.

[0032] like Figure 3 As shown, the displacement drive assembly 6 includes a guide rail 6-1, a moving platform 6-2, a drive motor 6-3, and a motor controller 6-4. The moving platform 6-2 is slidably connected to the guide rail 6-1 and can reciprocate under the drive of the drive motor 6-3. The motor controller 6-4 controls the rotation direction of the output shaft of the drive motor 6-3, thereby controlling the movement direction of the moving platform 6-2.

[0033] During use, turn on the dispensing assembly 4 and wait for the dispensing volume of the peristaltic tube 4-2 to stabilize. Then, start the drive motor 6-3 to drive the moving platform 6-2 to move on the guide rail 6-1, thereby moving the dispensing pen 4-1 and the peristaltic tube 4-2 on the dispensing pen 4-1 at a constant speed toward the other end of the suture to be glued. When the dispensing pen 4-1 approaches the end of the suture, the moving platform 6-2 stops moving.

[0034] In this embodiment, two limit sensors 6-5 are spaced apart on the guide rail 6-1 to limit the two extreme positions of the moving platform 6-2 during movement. When the moving platform 6-2 moves to the limit sensor 6-5, it will stop, which can accurately control the glue application length of the stitch.

[0035] Furthermore, the displacement drive component 6 also includes a timer 6-6. The timer 6-6 is integrated into the motor controller 6-4 and is used to display the elapsed time after the adhesive has been applied to the seam. In use, when the moving platform 6-2 moves to one end of the guide rail 6-1 and reaches the corresponding limit sensor 6-5, the limit sensor 6-5 sends a feedback signal to the motor controller 6-4 and the timer 6-6. The motor controller 6-4 then stops the drive motor 6-3 and starts the timer 6-6. The adhesive curing is complete after the timer expires.

[0036] In some embodiments, an alarm light is provided on timer 6-6 to promptly remind the operator after timer 6-6 has completed its countdown.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
