Description

Technical Field

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

[0002] In surgical suture manufacturing, barbed sutures are highly favored due to their unique suturing advantages. However, current barbed suture manufacturing technology has serious shortcomings. Traditional methods struggle to achieve precise multi-angle, spiral barb cutting when creating barbs for surgical sutures. Most methods employ straight-line cutting or simple, repetitive cutting patterns, resulting in a uniform barb distribution that fails to fully utilize the optimal performance of barbed sutures. For example, in actual suturing, a uniformly distributed barb can cause the suture to be unstable within the tissue, affecting wound healing. Furthermore, manual cutting angles and positions are difficult to control precisely, leading to extremely low efficiency and failing to meet the urgent needs of the modern medical industry for high-quality, high-volume surgical sutures. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a surgical suture processing rotary device that enables a cutter to cut at different positions, thereby forming spirally distributed barbs and enhancing the suturing effect of the surgical suture.

[0006] The surgical suture processing rotary device according to the first aspect of this application has at least the following beneficial effects: the clamping drive structures of the two rotary clamping mechanisms cooperate with each other to clamp the surgical suture, preventing the suture from moving during processing. The rotary drive structure can drive the clamping drive structure and the clamped surgical suture to rotate together. After the barb-cutting blade completes a cut and lifts to form a barb, the rotary clamping mechanism rotates at a set angle. At this time, the suture rotates along with it. Then the blade falls again to cut, forming the next barb, and so on, realizing spiral cutting of barbs. In this application, the rotation angle is precisely controlled by the rotary drive structure. In conjunction with the blade, the traditional straight or simple repetitive cutting mode is changed. After each cut, the rotary clamping mechanism drives the suture to rotate at a specific angle, so that the blade can cut at different positions, thereby forming spirally distributed barbs. Moreover, the automated rotation and cutting process greatly improves the processing efficiency, meets the needs of surgical sutures for multi-angle distribution of barbs, and enhances the suturing effect of surgical sutures.

[0028] In surgical suture manufacturing, barbed sutures are highly favored due to their unique suturing advantages. However, current barbed suture manufacturing technology has serious shortcomings. Traditional methods struggle to achieve precise multi-angle, spiral barb cutting when creating barbs for surgical sutures. Most methods employ straight-line cutting or simple, repetitive cutting patterns, resulting in a uniform barb distribution that fails to fully utilize the optimal performance of barbed sutures. For example, in actual suturing, a uniformly distributed barb can cause the suture to be unstable within the tissue, affecting wound healing. Furthermore, manual cutting angles and positions are difficult to control precisely, leading to extremely low efficiency and failing to meet the urgent needs of the modern medical industry for high-quality, high-volume surgical sutures.

[0029] Based on this, this application provides a surgical suture processing rotary device to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0030] Reference Figures 1 to 3 This application provides a rotating device for processing surgical sutures, including a mounting platform 100 and a rotating clamping mechanism 200. At least two rotating clamping mechanisms 200 are provided, respectively disposed at both ends of the mounting platform 100, and are arranged opposite to each other. Each rotating clamping mechanism 200 includes a rotating drive structure 210, a clamping drive structure 220, and a support unit 230. The support unit 230 is disposed on the mounting platform 100 and has a second threading opening for the surgical suture to be processed to pass through. The rotating drive structure 210 is disposed on the support unit 230, and its drive end is connected to the clamping drive structure 220. The clamping drive structure 220 is used to clamp the surgical suture, and the rotating drive structure 210 is used to control the clamping drive structure 220 to rotate synchronously, thereby causing the surgical suture to rotate.

[0031] In this application, the surgical suture to be processed passes through the second suture opening on the support unit 230. The clamping drive structures 220 of the two rotary clamping mechanisms 200 cooperate to clamp the surgical suture, preventing it from moving during processing. The rotary drive structure 210 can drive the clamping drive structure 220 and the clamped surgical suture to rotate together. After the barb-cutting blade completes a cut and lifts to form a barb, the rotary clamping mechanism 200 rotates at a set angle. At this time, the suture rotates along with it. Then the blade falls again to cut, forming the next barb. This cycle is repeated to achieve spiral barb cutting. In this application, the rotary drive structure 210 precisely controls the rotation angle, which, in conjunction with the blade, changes the traditional straight or simple repetitive cutting mode. After each cut, the rotary clamping mechanism 200 drives the suture to rotate at a specific angle, allowing the blade to cut at different positions, thereby forming spirally distributed barbs. The automated rotation and cutting process greatly improves processing efficiency, meets the need for multi-angle distribution of barbs in surgical sutures, and enhances the suturing effect of surgical sutures.

[0032] Reference Figure 2 and Figure 3 It is understood that the rotary drive structure 210 includes a drive motor 211 and a turntable assembly. The turntable assembly includes a fixed part 212, a transmission part, and a rotating part 213. The fixed part 212 is located on the side of the support unit 230 near the other rotary clamping mechanism 200. The rotating part 213 is rotatably mounted on the fixed part 212. The fixed part 212 and the rotating part 213 are respectively provided with a first threading opening and a first threading hole at corresponding positions. Specifically, the first threading opening and the first threading hole correspond to the second threading opening. The transmission part is located inside the fixed part 212 and is connected to the drive end of the drive motor 211. The drive motor 211 is used to drive the rotating part 213 to rotate by driving the transmission part. The clamping drive structure 220 is mounted on the rotating part 213. When the drive motor 211 is running, it transmits power to the rotating part 213 through the transmission part to drive the rotating part 213 to rotate. The transmission part can be a gear drive, belt drive, or chain drive, etc., which is not limited in this application. When the rotating part 213 rotates under the drive of the transmission part, the clamping drive structure 220 and the surgical suture clamped by it also rotate, thereby realizing the function of rotating the suture at a set angle during the barb cutting process. The drive motor 211 can precisely control the speed and rotation angle, and together with the stable transmission of the transmission part, it enables the rotating part 213 and the clamped suture to rotate at the preset angle, which greatly improves the accuracy of angle control when spirally cutting barbs, so as to produce surgical sutures with more uniform barb distribution that meet strict medical standards.

[0033] Reference Figure 2It is understood that the turntable assembly also includes a first sensor 214 and a first sensing plate 215. The first sensor 214 is disposed at the fixed part 212 and located beside the rotating part 213, and the first sensing plate 215 is disposed on the outer side of the rotating part 213. The first sensor 214 is used to determine the rotational position of the rotating part 213 by sensing the first sensing plate 215. When the surgical suture processing rotating device is running, the drive motor 211 drives the transmission part, thereby causing the rotating part 213 to rotate. The first sensing plate 215 is provided on the outer side of the rotating part 213, and the first sensor 214 is disposed at the position of the fixed part 212 beside the rotating part 213. When the rotating part 213 rotates, the first sensing plate 215 will rotate with the rotating part 213. Once the first sensing plate 215 enters the sensing range of the first sensor 214, the first sensor 214 can sense the presence of the first sensing plate 215 and convert this signal into an electrical signal or other identifiable signal output. The rotational position of the rotating part 213 is determined by sensing the first sensing plate 215 through the first sensor 214, which enables precise control of the rotation angle of the surgical suture. During the barb cutting process, precise rotational position control ensures that the cutting position of each barb is accurate, making the distribution of barbs on the suture more uniform and regular, thereby improving the processing accuracy and quality of the surgical suture.

[0034] Reference Figure 2 It is understood that the rotary drive structure 210 also includes a guide structure, which includes a mounting block 216 and a guide post 217. The mounting block 216 is disposed on the rotating part 213, and the clamping drive structure 220 and the guide post 217 are disposed on the mounting block 216. The mounting block 216 and the guide post 217 are respectively provided with a second threading hole and a third threading hole corresponding to the position of the first threading hole. During the surgical suture processing, the surgical suture to be processed first passes through the first threading opening of the fixing part 212 and the first threading hole of the rotating part 213, then enters the second threading hole of the mounting block 216, and finally passes through the third threading hole of the guide post 217. The mounting block 216 in the guide structure is fixed on the rotating part 213, and the guide post 217 is mounted on the mounting block 216. They rotate together with the rotating part 213. This allows the surgical suture to be precisely guided through a series of threading holes and guide posts 217 before being clamped by the clamping drive structure 220, ensuring that the suture is in the correct position and preparing it for subsequent processing operations. This reduces problems such as uneven barb cutting or inaccurate positioning caused by suture position deviation, thereby improving the processing accuracy and quality of the surgical suture.

[0035] Reference Figure 2It is understood that the guiding structure also includes a limiting and fixing claw 218, which is located at the end of the guide post 217 away from the mounting block 216. The limiting and fixing claw 218 has a limiting area for the surgical suture to pass through, and the width of the limiting area matches the diameter of the surgical suture. During the processing of the surgical suture, when the suture passes through each suture hole in sequence and reaches the guide post 217, it will enter the limiting area of ​​the limiting and fixing claw 218. Since the width of the limiting area matches the diameter of the surgical suture, the suture will be confined within this specific area and cannot move or deviate at will. When the rotating part 213 drives the guiding structure to rotate, the limiting and fixing claw 218 tightly constrains the surgical suture through the limiting area, so that it can only move along the predetermined rotation path, thereby ensuring that the suture is always in an accurate position during the barb cutting process and ensuring the cutting accuracy of the barb.

[0036] Reference Figure 2 It is understood that the rotary drive structure 210 also includes a feed sensor 219, which is located between the mounting block 216 and the rotating part 213. A fourth suture hole is provided at the corresponding position of the first suture hole. The feed sensor 219 is used to detect whether a surgical suture is present in the fourth suture hole. The feed sensor 219 continuously detects the presence of a surgical suture in the fourth suture hole through its own sensing mechanism. Its sensing principle is typically based on optical, electrical, or mechanical methods. For example, using photoelectric sensing, when a suture passes through the fourth suture hole, it will block light or cause a change in the photoelectric signal, thus allowing the feed sensor 219 to sense the presence of the suture; or using capacitive sensing, the entry of the suture will change the capacitance value, which will then be detected by the sensor. Once a suture is detected, the feed sensor 219 generates a corresponding electrical signal and transmits it to the control system of the device, informing the system that the surgical suture has reached the designated position. The system can then control subsequent processing steps based on this signal, such as activating the rotary drive structure 210 or controlling the barb-cutting tool to start working.

[0037] Reference Figure 2 and Figure 3It is understood that the clamping drive structure 220 includes a pneumatic finger 221 and two clamping plates 222. The two clamping plates 222 are respectively connected to the two drive ends of the pneumatic finger 221. The pneumatic finger 221 is used to control the two clamping plates 222 to move closer or further apart, thereby clamping or releasing the surgical suture. When compressed air is introduced into the pneumatic finger 221, its internal piston or diaphragm and other components will be displaced under the action of air pressure. This displacement is converted into the movement of the two drive ends through a mechanical transmission mechanism. The two clamping plates 222 are respectively connected to the two drive ends of the pneumatic finger 221. When the drive ends of the pneumatic finger 221 are driven inward by air pressure, the two clamping plates 222 will move closer to each other, thereby clamping the surgical suture placed between them; conversely, when the air pressure in the pneumatic finger 221 is released, the drive ends move outward under the action of the built-in reset structure, and the two clamping plates 222 will move further apart, releasing the clamping of the surgical suture.

[0038] Understandably, the two clamps 222 have positioning slots on opposite sides, the diameter of which matches the diameter of the surgical suture. When the pneumatic finger 221 controls the two clamps 222 to clamp the surgical suture, the suture is placed in the positioning slots on opposite sides of the clamps 222, fitting snugly into the slots. The inner wall of the positioning slot fits tightly against the outer circumference of the suture, limiting its position from multiple directions. This ensures that the suture remains within the defined position under the clamping of the clamps 222, preventing displacement in the horizontal or vertical directions, thus achieving precise positioning and stable clamping of the surgical suture.

[0039] It is understood that the surgical suture processing rotary device provided in this application also includes a sliding mechanism 300. Specifically, the sliding mechanism 300 is disposed on the mounting platform 100, and the sliding mechanism 300 has at least one movable end, on which at least one rotary clamping mechanism 200 is disposed. The sliding mechanism 300 is used to drive the rotary clamping mechanism 200 to move closer to or away from another rotary clamping mechanism 200. The sliding mechanism 300 may include components such as a motor, a lead screw, a guide rail, and a slider. The rotary clamping mechanism 200 is mounted on the movable end, so when the slider moves, it will drive the rotary clamping mechanism 200 to move together. By controlling the forward and reverse rotation of the motor, the rotation direction of the lead screw can be changed, thereby causing the slider to drive the rotary clamping mechanism 200 to move closer to or away from another rotary clamping mechanism 200, thereby adjusting the distance between the two rotary clamping mechanisms 200 to accommodate surgical sutures of different lengths or with different processing requirements, expanding the applicability of the equipment and improving its versatility and flexibility.

[0040] Understandably, a second sensing plate 311 is provided at the bottom of the mobile end, and a second sensor 312 is provided at the corresponding position of the sliding mechanism 300. The second sensor 312 is used to determine the position of the corresponding rotary clamping mechanism 200 by sensing the second sensing plate 311. When the mobile end moves on the sliding mechanism 300, the second sensing plate 311 installed at the bottom of the mobile end will also move accordingly. When the second sensing plate 311 moves into the sensing range of the second sensor 312, the second sensor 312 will sense the presence of the second sensing plate 311 or the change in physical quantity it causes. Through the arrangement of the second sensing plate 311 and the second sensor 312, the position of the rotary clamping mechanism 200 can be accurately determined, providing accurate position information for the automated control of the equipment and ensuring the precision and consistency of processing.

[0041] Secondly, this application also provides a surgical suture barb cutting device, comprising a feeding device, a suture cutting device, and a surgical suture processing rotating device arranged sequentially according to any embodiment of the first aspect. The feeding device conveys the surgical suture to be processed to the surgical suture processing rotating device. After the surgical suture is clamped by two rotating clamping mechanisms of the processing rotating device, the suture between the feeding device and the surgical processing rotating device is cut by the suture cutting device.

[0042] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
