TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a suture control assembly convenient to operate. BACKGROUND

[0002] A surgical stapler is a medical device used for surgical suturing. The anastomotic staple is a staple used in surgery to replace the suture to close, connect or resect parts of the intestine or lung. The anastomotic technique of the anastomotic stoma is the focus of debate, and complications of anastomotic surgery are occasionally seen, mainly causing leakage, bleeding, stenosis, ulceration, bleeding, etc. Due to the low incidence of complications, it has not been given sufficient attention, and once it occurs, it will increase many unexpected difficulties and processes for treatment. Postoperative anastomotic leakage is one of the most important surgical complications, which can cause life-threatening septic complications, including mediastinitis. Thoracic esophagogastric anastomosis leads to anastomotic leakage rate of 5~40%.

The trigger is linked with the first gear through the first linkage assembly, when the trigger rotates in the third direction, the first gear rotates, and the driving tooth is located at the tooth tip of the first tooth or the tooth valley.

[0007] The first linkage assembly comprises a second gear, a push piece, a guide plate and a first torsion spring, the second gear is coaxially arranged on one side of the first gear, the ring side of the second gear is uniformly provided with a plurality of second teeth in a circle, the number of the second teeth is twice the number of the first teeth, and the diameter of the second gear is greater than that of the first gear. The guide plate is arranged on the mounting base, the push piece is rotationally arranged on the trigger through a second rotating shaft, the first torsion spring is sleeved on the second rotating shaft, two ends of the first torsion spring are arranged on the push piece and the trigger respectively, the push piece is arranged on the ring side of the first rotating shaft, one side of the guide plate close to the trigger is a guide surface, part of the guide surface extends to one side of the axial side of the second gear, the overhanging end of the push piece abuts against the guide surface, part of the overhanging end of the push piece is located on the ring side of the second gear, and part of the second teeth extends to one side of the guide surface close to the trigger. The mounting base is provided with a limiting assembly for enabling the second gear to rotate only in the fourth direction.

[0008] The limiting assembly comprises a ratchet wheel, a pawl, a rotating plate and a second torsion spring, the ratchet wheel is coaxially arranged on one side of the second gear away from the first gear, the rotating plate is arranged on the mounting base through a third rotating shaft, the second torsion spring is sleeved on the third rotating shaft, two ends of the second torsion spring are connected with the rotating plate and the mounting base respectively, the pawl is arranged on the rotating plate, and the pawl is clamped on the ring side of the ratchet wheel. The number of teeth of the ratchet wheel is consistent with the number of the second teeth.

[0009] Two arc-shaped grooves in the shape of a circle arc are arranged on the lock rod in parallel, an arc-shaped plate in the shape of a circle arc is arranged on the trigger, and the center of the arc-shaped plate is located on the axis of the first rotating shaft. When the driving tooth is located at the tip of the first tooth or at the tooth valley, the arc-shaped plate is located in different arc-shaped grooves.

[0010] It also includes the upper link, the lower link, and the second linkage assembly. The upper connecting rod and the lower connecting rod have their ends facing a first direction and a second direction, respectively. The upper connecting rod is disposed between the locking rod and the lower connecting rod. Both the upper connecting rod and the lower connecting rod are slidably disposed on the mounting base. The sliding direction of the upper connecting rod and the lower connecting rod is towards the first direction or the second direction. The trigger is linked to the upper link and the lower link through the second linkage component.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0019] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product or device.

[0020] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0021] refer to Figures 1-4 The suture control assembly shown includes: a mounting base 1, on which a locking rod 2, an upper connecting rod 3, a lower connecting rod 4, a trigger 5, a first linkage assembly, and a second linkage assembly are provided; Locking rod 2, upper connecting rod 3, and lower connecting rod 4 are all oriented towards the first direction (e.g., Figure 3 (as shown by arrow A in the middle) and the second direction ... Figure 3 As shown by arrow B in the middle, the upper connecting rod 3 is located between the locking rod 2 and the lower connecting rod 4. The locking rod 2, the upper connecting rod 3 and the lower connecting rod 4 are all slidably mounted on the mounting base 1. The sliding direction of the locking rod 2, the upper connecting rod 3 and the lower connecting rod 4 is towards the first direction or the second direction, and the first direction and the second direction are opposite to each other. Trigger 5 is rotatably mounted on mounting base 1 via the first pivot, and trigger 5 is oriented in a third direction (e.g., Figure 3 (as indicated by arrow C) or the fourth direction (such as...) Figure 3 (As shown by arrow D) Rotation, the third and fourth directions are opposite to each other. The trigger 5 is linked to the locking rod 2 through the first linkage component. The trigger 5 is linked to the upper link 3 and the lower link 4 through the second linkage component. When the trigger 5 rotates to the third direction, the locking rod 2 slides to the first or second direction. When the trigger 5 rotates, the upper link 3 and the lower link 4 slide to the first or second direction.

[0022] Because the trigger is linked to the locking lever 2, the upper connecting rod 3, and the lower connecting rod 4 through the first and second linkage components, during use, simply gripping the trigger 5 continuously and rotating it back and forth in the third and fourth directions will cause the upper connecting rod 3 and the lower connecting rod 4 to be pulled continuously. Each time the trigger 5 moves in the third direction, the position of the locking lever 2 will change, thereby satisfying the automatic needle feeding and locking of the suture needle, thus improving the convenience of use for doctors.

[0023] like Figures 2-4As shown, a first gear 6 and an elastic element are rotatably mounted on the mounting base 1. A locking lever 2 is located on one side of the first gear 6, and a driving tooth 7 is located on one side of the locking lever 2. The first gear 6 has a plurality of first teeth evenly arranged circumferentially on its ring side, with tooth valleys between adjacent first teeth. The driving tooth 7 is located on the ring side of the first gear 6, and the tooth tip direction of the driving tooth 7 is the same as the first direction. The extension line of the tooth tip direction of the driving tooth 7 passes through the axis of the first gear 6. The elastic element is located on the mounting base 1 and is used to apply a pulling force towards the locking lever 2 in the first direction. The trigger 5 is linked to the first gear 6 through a first linkage assembly. When the trigger 5 rotates in a third direction, the first gear 6 rotates, causing the driving tooth 7 to be located in the first tooth valley. At the tip or trough of the tooth, by rotating the trigger 5, the first gear 6 rotates, so that the tip of the drive tooth 7 is aligned with the tip or trough of the first tooth. Since the tips and troughs are located at different positions, combined with the tension of the elastic element, the locking rod 2 moves in the first or second direction, thereby achieving the purpose of adjusting the position of the locking rod 2. Furthermore, through the elastic force of the elastic element and the rotational movement of the first gear 6, the drive tooth 7 is aligned with the tip or trough of the tooth in sequence, so that the locking rod 2 stops precisely at both ends of the movement stroke in sequence. There is no need to set a locking structure, which simplifies the structure. The position of the locking rod 2 can be adjusted simply by rotating the trigger 5 in a third direction, which meets the needs of suturing surgery and is very convenient to operate.

[0024] Among them, such as Figures 2-5As shown, the first linkage assembly includes a second gear 8, a paddle 9, a guide plate 10, and a first torsion spring. The second gear 8 is coaxially disposed on one side of the first gear 6. The second gear 8 has a plurality of second teeth evenly arranged in a circumferential direction, the number of which is twice the number of the first teeth. The diameter of the second gear 8 is larger than the diameter of the first gear 6. The guide plate 10 is disposed on the mounting base 1. The paddle 9 is rotatably mounted on the trigger 5 via a second rotating shaft. The first torsion spring is sleeved on the second rotating shaft, with its two ends respectively disposed on the paddle 9 and the trigger 5. The paddle 9 is disposed circumferentially on the first rotating shaft. The side of the guide plate 10 near the trigger 5 is a guide surface, with a portion of the guide surface extending to one side of the second gear 8 in the axial direction. The suspended end of the paddle 9 abuts against the guide surface, with a portion of the suspended end of the paddle 9 located on the circumferential side of the second gear 8, and a portion of the second teeth extending to the side of the guide surface near the trigger 5. The mounting base 1 is provided with a limiting component to restrict the second gear 8 to rotate only in the fourth direction. By rotating the trigger 5 in a third direction, the paddle 9 moves along the guide surface until it abuts against the second tooth, causing the second gear 8 to rotate, which in turn causes the first gear 6 to rotate. When the trigger 5 rotates in a fourth direction, the paddle 9 resets. During the reset process, because the limiting component restricts the second gear 8 to rotate only in a third direction, the paddle 9 compresses the first torsion spring and passes over the second tooth to complete the reset. In this embodiment, by adjusting the angle of rotation of the trigger 5 in a third direction or adjusting the volume of the second tooth passing over the guide surface, each rotation of the trigger 5 in a third direction causes the second gear 8 to rotate by the angle of one second tooth. The number of second teeth is twice the number of first teeth, so that when the second gear 8 rotates by the angle of one second tooth, the first gear 6 rotates by half the angle of the first tooth. Thus, each time the trigger 5 rotates in a third direction, the first gear 6 rotates by half the angle of the first tooth. As the trigger 5 rotates continuously in a third direction, the locking lever 2 reciprocates.

[0025] like Figure 6 As shown, the limiting assembly includes a ratchet 11, a pawl 12, a rotating plate 13, and a second torsion spring. The ratchet 11 is coaxially disposed on the side of the second gear 8 away from the first gear 6. The rotating plate 13 is disposed on the mounting base 1 via a third rotating shaft. The second torsion spring is sleeved on the third rotating shaft, and its two ends are connected to the rotating plate 13 and the mounting base 1, respectively. The pawl 12 is disposed on the rotating plate 13 and is engaged with the ratchet 11 in the circumferential direction (the ratchet is restricted from rotating in the opposite direction by the meshing direction between the pawl and the back of the ratchet teeth). The number of teeth on the ratchet 11 is the same as the number of teeth on the second gear. Thus, by engaging the pawl 12 on the circumferential side of the ratchet 11, the ratchet can only rotate in the fourth direction. When the ratchet 11 rotates in the fourth direction, the pawl 12 moves away from the ratchet 11, compressing the second torsion spring, thereby allowing the second gear 8 to rotate only in the fourth direction.

[0026] Further optimizations include, for example Figure 4 and Figure 7As shown, two arc-shaped grooves 20 are arranged side by side on the locking lever 2. When the tip of the driving tooth 7 is aligned with the tip or valley of the first tooth, the centers of the two arc-shaped grooves 20 are located on the axis of the first rotating shaft. The trigger 5 is provided with an arc-shaped plate 14, the center of which is located on the axis of the first rotating shaft. When the driving tooth 7 is located at the tip or valley of the first tooth, the arc-shaped plate 14 is located in different arc-shaped grooves 20. That is to say, when the trigger 5 rotates in the third direction, the arc-shaped plate 14 will disengage from the locking lever 2 (leaving from one of the arc-shaped grooves 20). When the trigger 5 rotates in the fourth direction, since the locking lever 2 is stationary, the arc-shaped plate 14 will enter the other arc-shaped groove 20, thereby locking the locking lever 2. When the trigger 5 is stationary, the locking lever 2 also remains stationary.

[0027] like Figure 2 , Figure 3 , Figure 7 as well as Figure 8 As shown, the second linkage assembly includes a steering plate 15. The middle position of the steering plate 15 is rotatably mounted on the mounting base 1 via a fourth rotating shaft. Both ends of the steering plate 15 are provided with strip-shaped movable holes 16, and the length directions of the two movable holes 16 are consistent. One end of the upper connecting rod 3 and one end of the lower connecting rod 4 are respectively provided with a first mounting shaft and a second mounting shaft. The first mounting shaft and the second mounting shaft (the first rotating shaft, the second rotating shaft, the third rotating shaft, the fourth rotating shaft, and the first mounting shaft and the second mounting shaft are axially consistent) pass through the two movable holes 16 respectively. The trigger 5 is provided with a strip-shaped guide hole 17, which is located on the annular side of the first rotating shaft. The first mounting shaft passes through the guide hole 17. Thus, by The upper connecting rod 3 and the lower connecting rod 4 are respectively connected to the two ends of the steering plate 15. Therefore, by rotating the trigger 5, the steering plate 15 is rotated, and the upper connecting rod 3 and the lower connecting rod 4 move in opposite directions, thereby realizing the alternating movement of the sewing needle. Furthermore, an arc-shaped hole 18 is provided on the side of the guide hole 17 near the lower connecting rod 4. The arc-shaped hole 18 is connected to the guide hole 17. That is to say, when the trigger 5 rotates in the third direction until the first mounting shaft moves from inside the guide hole 17 to the intersection of the arc-shaped hole 18 and the guide hole 17, since the center of the arc-shaped hole 18 is located on the axis of the first rotating shaft, when the first mounting shaft moves inside the arc-shaped hole 18, the upper connecting rod 3 remains stationary, and only the lower connecting rod 4 is driven to move, thus meeting the needs of the sewing needle.

[0028] Further optimizations include, for example Figure 2As shown, the mounting base 1 is provided with a limit plate 19 in the fourth direction of the trigger 5. By setting the limit plate 19, the rotation of the trigger 5 is limited. When the trigger 5 abuts against the limit plate 19, the trigger 5, the locking rod 2, the upper connecting rod 3 and the lower connecting rod 4 are stationary. Furthermore, a third torsion spring is provided on the first rotating shaft. The two ends of the third torsion spring are respectively set on the first rotating shaft and the trigger 5. That is to say, the third torsion spring applies a force to the trigger 5 to rotate in the fourth direction, so that the trigger 5 can automatically reset after rotating in the third direction.

[0029] Further optimization involves installing three guide rails on the mounting base 1. The locking rod 2, upper connecting rod 3, and lower connecting rod 4 are slidably mounted on the three guide rails. By setting the three guide rails, the movement of the locking rod 2, upper connecting rod 3, and lower connecting rod 4 are guided and limited respectively, ensuring the accuracy of the suture needle.

[0030] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that are directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
