[0029] After the barbs of surgical sutures are removed, they need to be cut into segments and collected. This step directly affects the subsequent use and storage of the sutures. Currently, the cutting and collection of surgical sutures after barb removal largely relies on manual operation. Manual cutting not only makes it difficult to ensure the consistency of the segment length, affecting the uniformity of suture specifications, but also requires manual collection of the cut suture segments, which is inefficient and prone to contamination due to human contact, posing a risk to subsequent use.
[0030] Based on this, this application provides a sewing thread cutting device to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.
[0031] Reference Figure 1 This application provides a suture feeding device, including: a conveying device 100, a cutting device 200, and a receiving structure. The conveying device 100 is used to receive and convey surgical sutures that have undergone barb cutting. The cutting device 200 is disposed at the output end of the conveying device 100 and is used to receive the surgical sutures and cut them into segments. The receiving structure is disposed on the side of the cutting device 200 and is used to receive the surgical sutures that have fallen from the cutting device 200 and have been cut into segments.
[0032] The transmission device 100 receives and transports the surgical sutures that have undergone barbed cutting, ensuring a stable transmission of the sutures to the cutting device 200. The cutting device 200, located at the output end of the transmission device 100, cuts the transmitted sutures into segments. A receiving structure collects the segmented sutures beside the cutting device 200, forming a continuous automated processing flow. The stable transmission of the transmission device 100 ensures consistent suture placement upon entering the cutting device 200, facilitating precise segmentation and eliminating the problem of inconsistent segment lengths compared to manual cutting. Simultaneously, the receiving structure automatically collects the segmented sutures, eliminating manual collection, reducing human contact, improving processing efficiency, lowering the risk of suture contamination, and better meeting the needs of subsequent suture use and storage.
[0033] Reference Figure 3 It is understood that the shearing device 200 includes a support frame 210, an adjustment mechanism, and a shearing mechanism. The support frame 210 is positioned between the transmission device 100 and the receiving structure. The adjustment mechanism is mounted on the support frame 210, and its drive end is connected to the shearing mechanism. The adjustment mechanism is used to adjust the position of the shearing mechanism, which is used to cut the surgical sutures. The support frame 210 provides a stable mounting base for the adjustment mechanism and the shearing mechanism. The adjustment mechanism can flexibly adjust the position of the shearing mechanism, allowing it to be precisely aligned according to the cutting requirements of different specifications of surgical sutures, ensuring the accuracy of the cutting position and thus improving the consistency of the cutting length. With the cooperation of the adjustment mechanism, the shearing mechanism stably completes the cutting process, making the entire shearing process more reliable, further optimizing the material feeding effect, and better meeting the precision requirements of surgical suture processing.
[0034] Reference Figure 3It is understood that the adjustment mechanism includes a cylinder adapter plate 221 and a slide cylinder 222. The fixing part of the slide cylinder 222 is mounted on the support frame 210 via the cylinder adapter plate 221, and the driving part of the slide cylinder 222 is connected to the cutting mechanism. The cylinder adapter plate 221 provides a stable mounting and fixing structure for the slide cylinder 222, ensuring that the slide cylinder 222 can be firmly mounted on the support frame 210. The driving part of the slide cylinder 222 is directly connected to the cutting mechanism, which can drive the cutting mechanism to achieve smooth and precise position adjustment, allowing the cutting mechanism to quickly and accurately adapt to the cutting needs of surgical sutures of different specifications, thus improving the efficiency and accuracy of cutting position adjustment.
[0035] Reference Figure 3 It is understood that the cutting mechanism includes a blade holder 231, a finger cylinder 232, and a cutting blade 233. The fixed part of the finger cylinder 232 is connected to the driving part of the slide cylinder 222 through the blade holder 231. The two driving parts of the finger cylinder 232 are each equipped with a cutting blade 233, with the blade edges of the two cutting blades facing each other. The two driving parts of the finger cylinder 232 are equipped with opposing cutting blades 233, which can quickly complete the cutting action by opening and closing the driving part. The opposing blade design ensures that the surgical suture is subjected to uniform force during cutting, reducing suture pulling or deformation during the cutting process. This allows for more precise adaptation to the cutting needs of different suture specifications, further ensuring the consistency and reliability of the cutting process.
[0036] Reference Figure 2 It is understood that the transmission device 100 includes a mounting frame 110, a guiding and positioning mechanism, and a driving and conveying mechanism. The guiding and positioning mechanism includes a guide sleeve 121, which is disposed on the first side of the mounting frame 110. The guide sleeve 121 is used to receive the surgical suture after barb cutting. The driving and conveying mechanism is located beside the guide sleeve 121. The guide sleeve 121 can accurately receive the surgical suture after barb cutting, playing a preliminary guiding and positioning role for the suture and preventing the suture from deviating when entering the transmission path. It should be noted that the inner diameter of the channel inside the guide sleeve 121 matches the diameter of the surgical suture after barb cutting. The driving and conveying mechanism is located beside the guide sleeve 121 and can promptly receive and drive the suture after it has been guided and positioned, so that the suture can be conveyed to the cutting device 200 in a stable posture and direction. This ensures that the cutting device 200 can accurately receive the suture, improves the accuracy and continuity of the entire transmission process, and provides a reliable guarantee for the smooth progress of subsequent cutting processing.
[0037] Reference Figure 2It is understood that the drive delivery mechanism includes a first active delivery wheel 131 and a drive member 132. The first active delivery wheel 131 is disposed on the first side of the mounting frame 110 and located beside the guide sleeve 121. The upper surface of the first active delivery wheel 131 contacts the surgical suture. The drive member 132 is disposed on the second side of the mounting frame 110. The drive end of the drive member 132 passes through the mounting frame 110 and connects to the first active delivery wheel 131, and is used to drive the first active delivery wheel 131 to rotate so as to drive the surgical suture to be transported. The first active delivery wheel 131 contacts the upper surface of the surgical suture and can rotate stably under the drive of the drive member 132, providing continuous power for suture transport and ensuring that the suture can move smoothly after being output from the guide sleeve 121. In addition, the drive component 132 is located on the second side of the mounting frame 110, and its drive end passes through the mounting frame 110 and is connected to the first active conveying wheel 131. This layout not only avoids the interference of the drive component on the sewing thread transmission path, but also ensures the stability of power transmission, allowing the sewing thread to be transmitted to the cutting device 200 at a uniform speed, further improving the reliability of transmission.
[0038] Reference Figure 2 It is understood that the drive delivery mechanism also includes at least one second active delivery wheel 133 and a linkage component 134. The second active delivery wheel 133 is disposed on the first side of the mounting frame 110 and located next to the first active delivery wheel 131. The upper surface of the second active delivery wheel 133 contacts the surgical suture. The drive end of the drive component 132 is connected to the second active delivery wheel 133 through the linkage component 134. The second active delivery wheel 133 and the first active delivery wheel 131 are arranged side by side on the first side of the mounting frame 110, and both contact the upper surface of the surgical suture. They are driven to rotate synchronously by the same drive component 132 through the linkage component 134, which can provide a more balanced and continuous driving force for suture transmission, avoid the transmission instability or slippage problems that may occur with a single delivery wheel, and further improve the reliability of transmission.
[0039] Reference Figure 2It is understood that the mounting frame 110 has a slide rail 111 on the first side in the vertical direction. The guiding and positioning mechanism includes a movable plate 135 and a driven positioning wheel 136. The movable plate 135 is movably mounted on the slide rail 111 via a slider. The driven positioning wheel 136 is located on the first side of the movable plate 135. The movable plate 135 is used to move towards the first active conveying wheel 131 so that the driven positioning wheel 136 contacts the upper surface of the surgical suture. The slide rail 111 on the mounting frame 110 cooperates with the slider on the movable plate 135, allowing the movable plate 135 to move stably in the vertical direction, thereby driving the driven positioning wheel 136 to accurately approach or move away from the first active conveying wheel 131. During transportation, when the driven positioning wheel 136 contacts the upper surface of the surgical suture, it cooperates with the first active conveying wheel 131 to effectively constrain the suture, preventing the suture from tilting upwards or shifting during transportation, ensuring that the suture always adheres to the conveying wheel for stable transportation, and further improving the accuracy of transportation.
[0040] Continue to refer to Figure 2 It is understandable that the mounting bracket 110 is also equipped with a push-pull quick clamp 137 above the slide rail 111. The push-pull quick clamp 137 includes a push-pull piston rod 138, a push-pull handle 139, and a transmission component. The push-pull handle 139 is connected to one end of the push-pull piston rod 138 through the transmission component, and the other end of the push-pull piston rod 138 is connected to the movable plate 135. The push-pull piston rod 138 is used to rotate to move in the vertical direction, thereby controlling the position of the movable plate 135 in the vertical direction. The push-pull quick clamp 137, through the rotation of the push-pull handle 139, drives the push-pull piston rod 138 to move in the vertical direction via the transmission component, thereby conveniently controlling the position of the movable plate 135, so that the driven positioning wheel 136 can quickly adjust its contact state with the surgical suture. Operators can easily adjust the suture constraint force, which can not only adapt to the transmission needs of different suture specifications, but also facilitate quick operation when changing sutures or dealing with abnormalities, thus improving the flexibility and efficiency of the equipment.
[0041] Reference Figure 1 It is understood that the material receiving structure includes a feeding chute 310 and a receiving basket 320. The feeding inlet of the feeding chute 310 is located below the shearing device 200, and the receiving basket 320 is located at the discharging outlet of the feeding chute 310. The feeding inlet of the feeding chute 310, located below the shearing device 200, can promptly receive the surgical suture segments that fall from the shearing device 200. Guided by the chute, the sutures slide orderly into the receiving basket 320. The receiving basket 320 centrally collects the suture segments, avoiding the mess or contamination caused by scattered sutures. It also reduces manual intervention, improves material receiving efficiency, and ensures the cleanliness of the collection process, providing convenience for subsequent storage and use.
