[0002] Vascular anastomosis is a crucial surgical procedure used in a wide variety of surgeries. The quality of the anastomosis directly impacts surgical outcomes. End-to-side and side-to-side anastomosis are more complex and challenging than end-to-end anastomosis. These procedures involve connecting one vascular stump to an incision on the other side. These procedures are time-consuming and highly dependent on the operator's experience.

[0003] The suturing devices in related staplers have shortcomings such as unstable effects, high costs, and a narrow range of applications. For example, suturing devices that implant staples have shortcomings such as poor anastomosis effects and lack of biocompatibility due to factors such as the material, performance, and shape of the staples.

DETAILED DESCRIPTION

[0030] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0031] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0032] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0033] When expressions such as "at least one of A, B, and C, etc." are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0034] The suturing devices used in conventional anastomosis devices suffer from instability, high cost, and limited application. Conventional suture anastomosis is considered the gold standard for vascular anastomosis. Therefore, the present invention provides an end-to-side suture suturing device that is simple to operate, provides rapid anastomosis, and minimizes vascular damage.

[0035] Figure 1 A perspective view of a suturing device according to an embodiment of the present disclosure is schematically shown. Figure 2 A perspective view of a suturing device according to an embodiment of the present disclosure with the housing removed is schematically shown. Figure 3 A cross-sectional view schematically shows a suturing device in a first state according to an embodiment of the present disclosure. Figure 4 A cross-sectional view schematically shows a suturing device in a second state according to an embodiment of the present disclosure.

[0036] like Figures 1-4 As shown, an embodiment of the present disclosure provides a suturing device 100. The suturing device 100 can be used to cause a plurality of curved suturing needles 200 to penetrate a first object to be sutured. Suture threads can be connected to the tails of the suturing needles 200. The suture threads can be connected to a second object to be sutured. The second object to be sutured can be a graft vessel to be transplanted. The first object to be sutured can be a target vessel. The second object to be sutured can be pre-threaded into the tails of the suturing needles 200 using suture threads, thereby maintaining the second object away from the first object to be sutured. After the suturing needles penetrate the first object to be sutured, the first and second objects to be sutured can be sutured together.

[0037] According to an embodiment of the present disclosure, the suturing device 100 may include a housing 110, a lifting assembly 120, and a guide assembly 130. An opening 113 may be formed at the top of the housing 110. The housing 110 may include an upper cover 111 and a lower housing 112. A plurality of circumferentially distributed needle inlets 114 may be formed on the circumferential surface of the housing 110. A needle outlet 115 may be formed below the needle inlet 114. The suturing needle 200 may enter the suturing device 100 through the needle inlet 114 and exit the suturing device 100 from the needle outlet 115. The needle inlet 114 and the needle outlet 115 may both be formed on the lower housing 112. The needle entry port 114 can extend all the way to the upper edge of the lower housing 112. The upper cover 111 can be formed with ribs that match the shape of the needle entry port 114 so that when the upper cover 111 and the lower housing 112 are fastened together, the ribs can be embedded in the needle entry port 114, thereby improving the stability of the installation between the upper cover 111 and the lower housing 112. Furthermore, the lower housing 112 can be formed into two elliptical cylinders. The diameter of the first elliptical cylinder is larger than the diameter of the second elliptical cylinder. The needle entry port 114 can be formed on the first elliptical cylinder, and the needle exit port 115 can be formed on the second elliptical cylinder.

[0038] Furthermore, the lifting assembly 120 can be disposed within the housing 110. The external drive wire 300 can pass through the opening 113 and connect to the lifting assembly 120, thereby driving the lifting assembly 120 to move. The suturing needle 200 can extend from the needle inlet 114 through the lifting assembly 120 to the needle outlet 115, thereby driving the lifting assembly 120 to drive the suturing needle 200 to move.

[0039] The guide assembly 130 can be disposed within the housing 110, near the needle exit port 115, and between the lifting assembly 120 and the suturing needle 200. By lifting the lifting assembly 120, the lifting assembly 120 can propel the suturing needle 200 and the guide assembly 130, respectively, so that the suturing needle 200, under the pressure of the guide assembly 130, passes through the needle exit port 115 and penetrates the first object to be sutured. In other words, during the upward movement of the lifting assembly 120, the lifting assembly 120 can simultaneously propel the suturing needle 200 and the guide assembly 130. By propelling the suturing needle 200, the suturing needle 200 can pass through the needle exit port 115 and thus penetrate the first object to be sutured. Furthermore, by providing the lifting assembly 120, multiple suturing needles 200 can be simultaneously propel through the first object to be sutured, achieving higher anastomosis efficiency and thus meeting the need to shorten vascular anastomosis surgery time. For example, eight needle entry ports 114 and exit ports 115 can be provided to simultaneously control eight suturing needles 200. After the suture needle 200 penetrates the first sutured object, the operator can pull the suture needle 200 out of the suture device 100 by hand or with a tool to perform subsequent knotting operations. Furthermore, by providing the guide assembly 130, the suture needle 200 can be squeezed, thereby preventing the suture needle 200 from deviating from the predetermined motion track, thereby improving the accuracy of the anastomosis.

[0040] According to the disclosed embodiment, by providing multiple needle entry ports 114 and needle exit ports 115, multiple suture needles 200 can be accommodated simultaneously. By providing a lifting assembly 120, multiple suture needles 200 can be simultaneously pushed through the first sutured object, thereby achieving higher anastomosis efficiency. By providing the lifting assembly 120 to push the guide assembly 130, multiple suture needles 200 can be squeezed simultaneously, thereby preventing the suture needles 200 from deviating from the predetermined motion trajectory, thereby improving the accuracy of the anastomosis, and simplifying the operation and reducing the cost.

[0041] like Figure 3-Figure 4 As shown, in some embodiments, the lifting assembly 120 may include a driven member 121 and a driving member 122. The driven member 121 may be formed with a central hole 123 and a plurality of lifting holes 124 distributed in the circumferential direction of the driven member 121. The suturing needle 200 may extend from the needle inlet 114 through the lifting holes 124 to the needle outlet 115. The lifting assembly 120 may push the suturing needle 200 to move through the contact force between the lifting holes 124 and the suturing needle 200.

[0042] The active member 122 can be disposed at the bottom of the housing 110. The driving wire 300 can sequentially pass through the opening 113 and the center hole 123 to connect with the active member 122. Figure 3As shown, the active member 122 can be located below the driven member 121, and the driven member 121 can be driven to move by pulling the active member 122. The guide assembly 130 can be disposed on the outer periphery of the active member 122.

[0043] According to the embodiment of the present disclosure, the active member 122 may be formed with an inclined surface 125. By pulling the active member 122, the active member 122 can drive the driven member 121 to move, so that the driven member 121 pushes the suture needle 200 to move, and at the same time, the inclined surface 125 can push the guide assembly 130 to squeeze the suture needle 200, so that the suture needle 200 passes through the needle outlet 115 under the squeezing of the guide assembly 130. Figure 3-Figure 4 As shown, the inclined surface 125 can be inclined downward toward the guide assembly 130, that is, the outer diameter of the active member 122 gradually increases from top to bottom. During the upward movement of the active member 122, the active member 122 changes from not contacting the guide assembly 130 to contacting the guide assembly 130, thereby driving the guide assembly 130 to move toward the suture needle 200. The active member 122 can be in the shape of an inverted funnel.

[0044] like Figure 1 As shown, in some embodiments, the housing 110 may be formed with a first thread exit seam 116 that communicates with the needle inlet 114 and the needle outlet 115. The follower 121 may be formed with a second thread exit seam 126 that communicates with the lifting hole 124. After the suture needle 200 penetrates the first material to be sutured, the suture thread connected to the tail of the suture needle 200 can be removed from the suture device 100 through the first thread exit seam 116 and the second thread exit seam 126. The width of the first thread exit seam 116 and the second thread exit seam 126 can be smaller than the width of the suture needle 200 to prevent the suture needle 200 from falling out of the suture device 100 through the first thread exit seam 116 and the second thread exit seam 126.

[0045] like Figure 3-Figure 4 As shown, in some embodiments, a first groove 117 may be formed at the bottom of the housing 110. The guide assembly 130 may be disposed on the periphery of the first groove 117. The active member 122 may extend out of the guide assembly 130 from the first groove 117. By pulling the active member 122, the active member 122 may be moved away from the first groove 117. During the upward movement of the active member 122, the inclined surface 125 may push the guide assembly 130 to move in the radial direction of the first groove 117. Figure 3 As shown, in the first state where the suturing device 100 is not yet activated, the active member 122 can be located in the first groove 117, and the active member 122 and the driven member 121 are spaced apart, and the needle head of the suturing needle 200 can enter the needle inlet 114. Figure 4As shown, in the second state of the suturing device 100, the active member 122 can be pulled up to be out of the first groove 117, thereby driving the driven member 121 to move. The height to which the active member 122 rises can be less than the height at which the active member 122 separates from the guide assembly 130, thereby ensuring that the active member 122 can abut against the guide assembly 130 and preventing the guide assembly 130 from falling into the first groove 117.

[0046] like Figure 3 As shown, in some embodiments, a first slope 127 that is inclined downward toward the central axis of the suturing device 100 may be formed on one side of the lifting hole 124 close to the needle outlet 115. The first slope 127 can push the suture needle 200 to move toward the needle outlet 115. The lifting hole 124 can be formed into a prism shape. The minimum length of the lifting hole 124 is slightly larger than the diameter of the suture needle 200, so that the suture needle 200 remains stable in the lifting hole 124. The lower end of the first slope 127 can be closer to the suture needle 200 relative to the upper end. The geometric center of the suture needle 200 can be close to the first slope 127 of the lifting hole 124. Figure 3 As shown, the suture needle 200 on the right side moves toward the needle outlet 115 under the push of the right slope (i.e., the first slope 127) of the right lifting hole 124. The suture needle 200 on the left side moves toward the needle outlet 115 under the push of the left slope (i.e., the first slope 127) of the left lifting hole 124.

[0047] Figure 5 A perspective view of a guide pad according to an embodiment of the present disclosure is schematically shown. Figure 6 A perspective view of a guide seat according to an embodiment of the present disclosure is schematically shown.

[0048] like Figure 2-Figure 6 As shown, in some embodiments, the guide assembly 130 may include a plurality of guide blocks 131. Each guide block 131 may be close to a needle outlet 115. The suturing device 100 may further include a guide seat 140. The guide seat 140 may be arranged on the periphery of the first groove 117, that is, the periphery of the active member 122. The guide seat 140 may be formed with a plurality of guide grooves 141 that match the shape of the guide block 131. The plurality of guide grooves 141 may be distributed in the circumferential direction of the guide seat 140. The inclined surface 125 may push the guide block 131 to move along the guide groove 141. A positioning hole 142 may be formed on the guide seat 140. The guide seat 140 may be installed on the periphery of the first groove 117 through the cooperation of the positioning hole 142 and the fixing pin 143. As shown Figure 5-Figure 6As shown, the guide block 131 and the guide groove 141 can be of a special-shaped structure, thereby increasing the friction between the guide block 131 and the guide groove 141, preventing the guide assembly 130 from disengaging from the guide seat 140, and improving the accuracy of the movement of the guide block 131. The end of the guide block 131 can be elastic. For example, the end of the guide block 131 can be connected to an elastic member to increase the friction between the guide block 131 and the suture needle 200. The elastic member can be made of an elastic material such as rubber.

[0049] like Figure 3-Figure 6 As shown, in some embodiments, a second slope 133 may be formed on one side of the guide block 131 near the needle exit 115. The second slope 133 compresses the suture needle 200, allowing it to pass through the needle exit 115 and penetrate the first sutured object. Furthermore, the guide block 131 may be formed with a notch 132 that matches the shape of the suture needle 200. The notch 132 may have two opposing side surfaces and a second slope 133 at the bottom. The provision of the notch 132 can restrict the movement of the suture needle 200 through the notch 132 to the needle exit 115, thereby preventing the suture needle 200 from deviating from its predetermined trajectory.

[0050] like Figure 3-Figure 4 As shown, in some embodiments, a second groove 128 can be formed on one side of the driven member 121 close to the active member 122 to match the shape of the top of the active member 122. When the active member 122 is pulled to the driven member 121, the top of the active member 122 can be embedded in the second groove 128 to drive the driven member 121 to move together.

[0051] Figure 7 A side view of a suturing device in combination with a winding wheel 500 according to an embodiment of the present disclosure is schematically shown.

[0052] like Figure 7 As shown, in some embodiments, the suturing device 100 can also be used in conjunction with a drive device. For example, a winding wheel 500. The winding wheel 500 can be wound with a drive wire 300 for pulling the active member 122. The winding wheel 500 can be connected to the output shaft of the motor. The motor can drive the winding wheel 500 to rotate, thereby pulling the active member 122.

[0053] Figure 8 A side view of a stapler according to an embodiment of the present disclosure is schematically shown.

[0054] like Figure 8As shown, the present disclosure also provides a stapler. The stapler may include the suturing device 100 described above, a handle portion 600 and a connecting portion 700. The handle portion 600 may include a main handle 610 and an auxiliary handle 620. The main handle 610 may include a handle housing 611, a guide rod 612 and a slider 613. The guide rod 612 may be disposed in the handle housing 611. The slider 613 may be slidably disposed on the guide rod 612 and connected to the lifting assembly 120 of the suturing device 100 via a drive wire 300. One end of the auxiliary handle 620 (as shown in FIG. 1 ) may be provided with a guide rod 612 and a slider 613. Figure 8 The upper end of the auxiliary handle 620 (as shown) can be pivotally mounted on the handle housing 611 via a pivot 630. The other end of the auxiliary handle 620 (as shown) Figure 8 The auxiliary handle 620 (shown at the lower end) can be connected to the slider 613 via a connecting rod 640. When the auxiliary handle 620 rotates around the pivot 630, the connecting rod 640 drives the slider 613 to slide along the guide rod 612, thereby lifting the lifting assembly 120. The auxiliary handle 620 can be formed with a curved surface that fits the palm of the operator. An array of convex points can be formed on the curved surface, which can apply a certain friction force to the palm, thereby facilitating the operator to perform delicate operations. The connecting portion 700 can be connected to the grip portion 600 and the suturing device 100 respectively. The connecting portion 700 can be connected to the suturing device 100 by a threaded connection. The connecting portion 700 can be connected to the grip portion 600 by a keyway fit. The drive wire 300 can be connected from the grip portion 600 through the connecting portion 700 to the lifting assembly 120.

[0055] like Figure 8 As shown, in some embodiments, a guide post 615 may be further formed in the handle housing 611. The drive wire 300 may be wound around the guide post 615 and then connected to the slider 613, so that the drive wire 300 is always in a tensioned state and the length of the drive wire 300 can provide a certain tension between the slider 613 and the active member 122. Furthermore, the guide post 615 may also serve to guide the drive wire 300 to the slider 613.

[0056] like Figure 8 As shown, in some embodiments, the stapler may further include an elastic member 614. The elastic member 614 may be a return spring. The elastic member 614 may be mounted within the handle housing 611 and connected to the slider 613 to drive the slider 613 back to its inactive state without rotating the auxiliary handle 620. The elastic member 614 also makes the entire stapler more compact and, by generating an automatic rebound force, provides the user with a more realistic user experience.

[0057] like Figure 8As shown, in some embodiments, the handle portion 600 may further include an insert 650. The insert 650 is removably extendable from the exterior of the handle housing 611 to the guide rod 612. The slider 613 may be formed with a third groove that matches the shape of the insert 650. When the slider 613 slides along the guide rod 612 to the insert 650, the insert 650 engages with the third groove, preventing the auxiliary handle 620 from further rotating, thereby preventing the slider 613 from moving, thereby allowing the stapler to enter a third state, ready for operation. In the third state, the insert 650 prevents the slider 613 from moving, and the guide block 131 moves to a position that compresses the suture needle 200 but does not yet push it, thereby securing the suture needle 200 and preventing it from dislodging from the suturing device 100 during movement of the stapler. After removing the insert 650, the auxiliary handle 620 can be further rotated to further pull the lifting assembly 120, thereby entering the second state for suturing the first workpiece.

[0058] Figure 9 A three-dimensional diagram of a blood vessel externalization platform according to an embodiment of the present disclosure is schematically shown. Figure 10 A side view schematically shows an anastomosis apparatus according to an embodiment of the present disclosure used in conjunction with a vascular external platform. Figure 11 A three-dimensional view of an intravascular platform according to an embodiment of the present disclosure is schematically shown. Figure 12 A side view schematically shows an anastomosis apparatus according to an embodiment of the present disclosure used in conjunction with an intravascular platform 900 .

[0059] like Figures 9-12 As shown, in some embodiments, the stapler can also be used in conjunction with other tools. For example, an external vascular platform 800 and an internal vascular platform 900. When the suturing device 100 is in the first state, the suturing device 100 can be connected to a second object to be sutured, that is, the suturing needle 200 connected to the second object to be sutured is placed into the suturing device 100. After the stapler enters the third state, the suturing device 100 can be used in conjunction with other tools to enter the second state for suturing the first object to be sutured 400.

[0060] like Figure 9-10As shown, one end of the vascular external platform 800 can be formed with an external gripping end 810 for gripping. The other end of the vascular external platform 800 can be in the shape of a hollow disc. The circular hole 820 in the middle can be slightly larger than the minimum diameter of the housing 110. For example, it can be 1mm-2mm larger than the minimum diameter of the housing 110. This can better pull the target blood vessel so that it deforms to adapt to the use of the suturing device 100. Specifically, a hole can be punched in the area of ​​the first sutured object 400 to be anastomosed, or a circular piece of tissue can be cut. 2-4 sutures are sewn into this hole. By pulling the sutures, the edge of the hole in the anastomosis area is pulled up and partially fits the lower part of the housing 110. When the suture needle 200 passes through the needle outlet 115, it can also puncture the first sutured object 400.

[0061] like Figure 11-12 As shown, one end of the intravascular platform 900 may be formed with a built-in handle 910 for gripping. The other end of the intravascular platform 900 can be folded and unfolded. Specifically, the intravascular platform 900 may include a first primary connecting rod 920, a second primary connecting rod 930, a first secondary connecting rod 940, a second secondary connecting rod 950, a first tertiary connecting rod 960, and a second tertiary connecting rod 970. The first primary connecting rod 920 may be rotatably connected to the second primary connecting rod 930 and the first secondary connecting rod 940, respectively. The first secondary connecting rod 940 is rotatably connected and can also be rotatably connected to the second tertiary connecting rod 970. The second secondary connecting rod 950 may be rotatably connected to the second primary connecting rod 930 and the first tertiary connecting rod 960, respectively. The second secondary connecting rod 950 and the first secondary connecting rod 940 may be formed with a clearance groove to allow the second secondary connecting rod 950 and the first secondary connecting rod 940 to intersect. The first tertiary connecting rod 960 may also be rotatably connected to the second tertiary connecting rod 970. The first and second third-stage connecting rods 960, 970 can be connected to the internal gripping end 910. The intravascular platform 900 can be retracted into a linear form or expanded into a quadrilateral form. In the linear form, the intravascular platform 900 can be inserted into the target vessel through a pre-punctured hole and then expanded into a quadrilateral form to provide support for deformation of the target vessel.

[0062] By applying torque to the first and second tertiary links 960, 970, and causing them to shift, the operator can retract the intravascular platform 900 into a linear form or deploy it into a quadrilateral form. Retracting into a linear form requires the operator to apply a certain amount of gripping force to maintain the linear form. When deployed into a quadrilateral form, the first and second tertiary links 960, 970 allow the gripping ends to align, resulting in a more regular shape. An external locking ring can be attached to lock it into the quadrilateral form, which is also the conventional storage configuration for the intravascular platform 900. Specifically, the first sutured material 400 can be punctured, and the intravascular platform 900 can be retracted into a linear form. The linear form can then be inserted into the first sutured material 400 through the punctured hole, creating a hollow, rigid support. The lower portion of the housing 110 compresses the anastomotic region, deforming the anastomotic region on the first object 400 so that it conforms to the lower portion of the housing 110. When the suturing needle 200 passes through the needle exit 115, it penetrates the first object 400. At this point, the suturing device 100 and the anastomotic region of the first object 400 are tightly connected. Manually pressing the first object 400 at the outer edge of the anastomotic region can cause the suturing needle 200 to pass through the first object 400 again.
