Description

Technical Field

[0001] This application relates to the field of surgical suture processing technology, and in particular to a suture feeding device. Background Technology

[0002] In the processing of surgical sutures, the sutures need to be precisely fed to the barb-cutting device for subsequent processing. This step requires a high degree of stability and accuracy in the feeding process. Existing feeding methods mostly rely on manual operation or simple transmission structures. Manual feeding is not only inefficient and difficult to match the continuous processing rhythm of the barb-cutting device, but it is also prone to suture position deviation during feeding, leading to a decrease in the barb-cutting accuracy. Simple transmission structures lack effective guidance and positioning, and cannot ensure that the suture enters the barb-cutting device stably and in the correct posture, affecting the processing quality.

[0031] In the processing of surgical sutures, the sutures need to be precisely fed to the barb-cutting device for subsequent processing. This step requires a high degree of stability and accuracy in the feeding process. Existing feeding methods mostly rely on manual operation or simple transmission structures. Manual feeding is not only inefficient and difficult to match the continuous processing rhythm of the barb-cutting device, but it is also prone to suture position deviation during feeding, leading to a decrease in the barb-cutting accuracy. Simple transmission structures lack effective guidance and positioning, and cannot ensure that the suture enters the barb-cutting device stably and in the correct posture, affecting the processing quality.

[0032] Based on this, this application provides a sewing thread feeding device to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0033] Reference Figures 1 to 3 This application provides a suture feeding device that can be applied to a complete machine for producing surgical sutures, providing a feeding basis for surgical suture cutting equipment. The suture feeding device includes: a feeding chamber 100, a suture conveying device 200, and a transmission device 300. The side wall of the feeding chamber 100 is provided with an output port 110. The suture conveying device 200 is disposed in the feeding chamber 100 and is used to output the surgical suture from the output port 110. The transmission device 300 is disposed beside the feeding chamber 100 and includes a guiding and positioning mechanism 310 and a driving and conveying mechanism 320. The guiding and positioning mechanism 310 is used to receive the surgical suture output from the output port 110, and the driving and conveying mechanism 320 is used to drive the surgical suture to move in a specified direction. The feeding chamber 100 may be filled with inert gas to provide anti-oxidation protection for the surgical suture.

[0034] The suture feeding device 200 inside the feeding chamber 100 enables automated output of surgical sutures. Simultaneously, the side-mounted transmission device 300 accurately receives the output sutures via a guide and positioning mechanism 310, and the drive conveying mechanism 320 stably drives the sutures in a designated direction. This automated feeding and transmission structure replaces manual feeding, avoiding the inefficiencies and positional deviations caused by manual operation, thus improving the efficiency of surgical suture feeding. Furthermore, the coordination between guide positioning and drive conveying ensures the stability and directional accuracy of suture transmission, thereby improving the quality and continuity of barb removal processing and better meeting the processing and production needs of surgical sutures.

[0035] Reference Figure 4It is understood that the transmission device 300 also includes a first mounting bracket 330, and the guiding and positioning mechanism 310 includes a first guide sleeve 311. The first guide sleeve 311 is disposed on the first side of the first mounting bracket 330 and near one end of the loading chamber 100. The first guide sleeve 311 is used to receive surgical sutures output from the output port 110, and the drive conveying mechanism 320 is located on the rear side of the first guide sleeve 311. The transmission device 300 provides a stable mounting base for the guiding and positioning mechanism 310 and the drive conveying mechanism 320 through the first mounting bracket 330. The first guide sleeve 311, disposed on the first side of the first mounting bracket 330 and near one end of the loading chamber 100, can accurately align with the output port 110 of the loading chamber 100 and quickly receive the output surgical sutures, thereby reducing positional deviation. The drive conveying mechanism 320 is located on the rear side of the first guide sleeve 311, forming a continuous transmission path. It should be noted that the inner diameter of the channel of the first guide sleeve 311 matches the diameter of the surgical suture to prevent the surgical suture from shaking during transmission.

[0036] Reference Figure 4 It is understood that the guiding and positioning mechanism 310 also includes at least a second guide sleeve 312. The second guide sleeve 312 is disposed on the first side of the first mounting bracket 330 and at the end away from the feeding chamber 100. The channel of the second guide sleeve 312 and the channel of the first guide sleeve 311 are located on the same horizontal plane. The driving conveying mechanism 320 is located between the first guide sleeve 311 and the second guide sleeve 312. The second guide sleeve 312 and the first guide sleeve 311 are installed together on the first side of the first mounting bracket 330, and the second guide sleeve 312 is located at the end away from the feeding chamber 100. The channels of the two are on the same horizontal plane, and the driving conveying mechanism 320 is located between the two, forming a continuous and stable guiding path. This structure can quickly and accurately receive surgical sutures output from the output port 110, initially guiding and positioning the sutures to prevent them from deviating as soon as they leave the output port 110. The second guide sleeve 312, located at the end away from the feeding chamber 100, further guides and constrains the sutures after they have been driven by the drive conveyor mechanism 320, ensuring that the sutures maintain the correct posture before entering the subsequent barb cutting equipment, thus guaranteeing the stability and quality of subsequent processing.

[0037] Continue to refer to Figure 4It is understood that the drive conveying mechanism 320 includes a first active conveying wheel 321 and a drive member 322. The first active conveying wheel 321 is disposed on the first side of the first mounting frame 330 and located behind the first guide sleeve 311. The upper surface of the first active conveying wheel 321 contacts the surgical suture. The drive member 322 is disposed on the second side of the first mounting frame 330. The drive end of the drive member 322 passes through the first mounting frame 330 and connects to the first active conveying wheel 321, which is used to drive the first active conveying wheel 321 to rotate and drive the surgical suture to be conveyed. The direct contact between the first active conveying wheel 321 and the suture can provide a stable driving force, ensuring that the suture obtains continuous and uniform power during the transmission process and reducing transmission jamming. The structure of the drive member 322 and the conveying wheel being disposed on opposite sides of the mounting frame makes the overall layout more compact, which not only saves space but also avoids the drive component from obstructing or interfering with the suture transmission path, further improving the stability and smoothness of the transmission, and helping to ensure that the suture is delivered to the barb-cutting device in a stable state.

[0038] Continue to refer to Figure 4 It is understood that the drive conveying mechanism 320 also includes at least one second active conveying wheel 323 and a linkage component 324. The second active conveying wheel 323 is disposed on the first side of the first mounting bracket 330, located behind the first guide sleeve 311 and beside the first active conveying wheel 321. The upper surface of the second active conveying wheel 323 contacts the surgical suture. The drive end of the drive member 322 is connected to the second active conveying wheel 323 through the linkage component 324. In the drive conveying mechanism, the first active conveying wheel 321 and the second active conveying wheel 323 are arranged back and forth along the transmission direction to avoid uneven local force or slippage that may occur when a single wheel is used for transmission, thus ensuring that the suture maintains a stable posture and speed during transmission.

[0039] Continue to refer to Figure 4 It is understood that the first mounting bracket 330 has a first slide rail 331 in the vertical direction on the first side. The guide positioning mechanism 310 includes a first movable plate 340 and a first driven positioning wheel 341. The first movable plate 340 is movably mounted on the first slide rail 331 via a first slider. The first driven positioning wheel 341 is located on the first side of the first movable plate 340. The first movable plate 340 is used to move towards the first active conveying wheel 321 so that the first driven positioning wheel 341 contacts the upper surface of the surgical suture. The first driven positioning wheel 341 on the first movable plate 340 can move with the plate towards the first active conveying wheel 321, thereby contacting the upper surface of the surgical suture placed on the conveying wheel, forming an upper and lower limiting structure for the suture, preventing it from tilting upward or shifting during transmission, and adapting to the transmission needs of different specifications of sutures, ensuring that the suture is always stably attached to the conveying wheel, further improving the accuracy and reliability of transmission.

[0040] Continue to refer to Figure 4 It is understood that the first mounting frame 330 is also equipped with a push-pull quick clamp 350 above the first slide rail 331. The push-pull quick clamp 350 includes a push-pull piston rod 351, a push-pull handle 352, and a transmission component. The push-pull handle 352 is connected to one end of the push-pull piston rod 351 through the transmission component, and the other end of the push-pull piston rod 351 is connected to the first movable plate 340. The push-pull piston rod 351 is used to rotate to drive the push-pull piston rod 351 to move in the vertical direction, thereby controlling the position of the first movable plate 340 in the vertical direction. By setting the push-pull quick clamp 350 on the first mounting frame 330, and using the push-pull handle 352 connected to the push-pull piston rod 351 through the transmission component, the rotation of the handle is converted into the movement of the piston rod in the vertical direction, thereby driving the first movable plate 340 to move up and down along the first slide rail 331, realizing rapid control of the contact state between the first driven positioning wheel 341 and the surgical suture. By connecting the push-pull quick clamp 350 to the movable plate, it is easy to quickly adjust the equipment status when changing surgical sutures of different specifications, and can also interrupt the limit switch in time when transmission abnormalities occur, which improves the ease of operation, flexibility and flexibility of dealing with emergencies.

[0041] Reference Figure 1 and Figure 3 The suture feeding device provided in this application also includes a buffer device 400, which is disposed between the feeding chamber 100 and the transmission device 300. The buffer device 400 is used to receive the surgical sutures output from the output port 110 and to transport the surgical sutures to the transmission device 300. The buffer device 400 can effectively alleviate the tension fluctuations or transmission speed differences that may occur when the surgical sutures are output from the output port 110, and prevent the sutures from shifting or tangling due to uneven instantaneous force, allowing the sutures to enter the transmission device 300 in a more stable state, thereby improving the stability of the surgical suture transmission.

[0042] Reference Figure 5It is understood that the buffer device 400 includes a second mounting frame 410, a third guide sleeve 420, a driven conveying wheel 430, a second driven positioning wheel 440, and a second movable plate 450. The second mounting frame 410 is disposed between the feeding chamber 100 and the transmission device 300. The third guide sleeve 420 is disposed on the first side of the second mounting frame 410 and close to one end of the feeding chamber 100. The driven conveying wheel 430 is disposed on the first side of the second mounting frame 410 and located behind the third guide sleeve 420. The second movable plate 450 is vertically slidably disposed on the second mounting frame 410 and located above the driven conveying wheel 430. The second driven positioning wheel 440 is disposed on the first side of the second movable plate 450. The upper surface of the driven conveying wheel 430 and the lower surface of the second driven positioning wheel 440 are in contact with the surgical sutures, respectively. The second mounting bracket 410 provides stable support for all components of the buffer device 400. The third guide sleeve 420 can accurately receive the surgical sutures output from the output port 110 and initially guide them into the buffer path. The driven conveying wheel 430 cooperates with the second driven positioning wheel 440 on the vertically sliding second movable plate 450 to contact the surgical sutures from the upper and lower sides. The contact between the two can form a stable constraint on the sutures, and the vertical sliding of the second movable plate 450 can adapt to the tension changes during suture transmission, effectively buffering the fluctuations of the sutures during transmission and avoiding suture deviation or damage due to unstable tension. This allows the sutures to be transported from the buffer device 400 to the transmission device 300 in a more stable state, further ensuring the continuity and stability of the entire feeding process.

[0043] Reference Figure 2 and Figure 3 It is understood that the suture feeding device 200 includes a suture feeding shaft 210 and a servo tensioner 220. Both the suture feeding shaft 210 and the servo tensioner 220 are installed on the inner wall of the feeding chamber 100. The suture feeding shaft 210 is used to hold the suture bundle containing the surgical suture to be processed, and the servo tensioner 220 is used to drive the surgical suture in the suture bundle to be output from the output port 110. The suture feeding shaft 210 provides a stable placement structure for the surgical suture bundle containing the suture, facilitating the installation and replacement of the suture bundle; the servo tensioner 220 can precisely control the tension of the surgical suture during output, avoiding suture breakage due to excessive tension or suture loosening and tangling due to insufficient tension during output, ensuring that the surgical suture is output from the output port 110 in a stable and orderly state, providing a reliable foundation for the smooth operation of the subsequent buffer device 400 and transmission device 300.
