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 exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, 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 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 existence of features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0032] All terms (including technical and scientific terms) used herein 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 using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression 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] Since the suturing device in the related stapler has the disadvantages of unstable effect, high cost and narrow application range, the traditional suture anastomosis is regarded as the gold standard for vascular anastomosis. Therefore, the present invention provides a suturing device of end-to-side sutures that is easy to operate, fast in anastomosis and has little damage to the blood vessel.

Figure 2 A three-dimensional view of a suturing device according to an embodiment of the present disclosure with the shell 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 Figure 1-Figure 4 As shown, the embodiment of the present disclosure provides a suturing device 100. The suturing device 100 can be used to make a plurality of curved suturing needles 200 penetrate a first object to be sutured by operation. The tail of the suturing needle 200 can be connected with a suture thread. The suture thread can be connected with a second object to be sutured. The second object to be sutured can be a bridge vessel to be transplanted. The first object to be sutured can be a target vessel. The second object to be sutured can be pre-pierced into the tail of the suturing needle 200 by the suture thread, and the second object to be sutured can be kept away from the first object to be sutured. After the suturing needle penetrates the first object to be sutured, the first object to be sutured and the second object 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 pass through 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 may extend all the way to the upper edge of the lower shell 112, and a rib matching the shape of the needle entry port 114 may be formed on the upper cover 111, so that when the upper cover 111 and the lower shell 112 are buckled, the rib can be embedded in the needle entry port 114, thereby improving the stability of the installation between the upper cover 111 and the lower shell 112. Further, the lower shell 112 can be formed into two elliptical cylinders. The diameter of the first elliptical cylinder is greater 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] Further, the lifting assembly 120 can be disposed in the housing 110. The external driving wire 300 can pass through the opening 113 to connect with the lifting assembly 120, so as to drive the lifting assembly 120 to move. The suture needle 200 can extend from the needle inlet 114 through the lifting assembly 120 to the needle outlet 115, so as to drive the suture needle 200 to move by driving the lifting assembly 120.

[0039] The guide assembly 130 can be arranged in the housing 110, near the needle outlet 115, and between the lifting assembly 120 and the suture needle 200. By lifting the lifting assembly 120, the lifting assembly 120 can push the suture needle 200 and the guide assembly 130 to move respectively, so that the suture needle 200 passes through the needle outlet 115 and penetrates the first sutured object under the pressure of the guide assembly 130. In other words, during the upward movement of the lifting assembly 120, the lifting assembly 120 can simultaneously push the suture needle 200 and the guide assembly 130 to move. By pushing the suture needle 200 to move, the suture needle 200 can pass through the needle outlet 115, so that the first sutured object can be penetrated. Further, by setting the lifting assembly 120, multiple suture needles 200 can be pushed to penetrate the first sutured object at the same time, with a higher anastomosis efficiency, so as to meet the demand of shortening the vascular anastomosis operation time. For example, 8 needle inlets 114 and needle outlets 115 can be provided, so as to control 8 suture needles 200 at the same time. 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. Further, 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 embodiment of the present disclosure, by providing multiple needle inlets 114 and needle outlets 115, multiple suture needles 200 can be accommodated at the same time. By providing a lifting assembly 120, multiple suture needles 200 can be pushed to penetrate the first sutured object at the same time, with a higher anastomosis efficiency. By providing a lifting assembly 120 to push the guide assembly 130, multiple suture needles 200 can be squeezed at the same time, thereby preventing the suture needles 200 from deviating from the predetermined motion track, improving the accuracy of the anastomosis, and being easy to operate and low in 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 suture 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 suture needle 200 to move through the contact force between the lifting hole 124 and the suture needle 200.

[0042] The active member 122 may be disposed at the bottom of the housing 110. The driving wire 300 may pass through the opening 113 and the center hole 123 in sequence to connect with the active member 122. Figure 3As shown, the active member 122 may be located below the driven member 121 , and the driven member 121 may be driven to move by pulling the active member 122 . The guide assembly 130 may 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 may 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 may 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, and 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 an inverted funnel shape.

[0044] like Figure 1 As shown, in some embodiments, the housing 110 may be provided with a first thread outlet seam 116 communicating with the needle inlet 114 and the needle outlet 115. The follower 121 may be provided with a second thread outlet seam 126 communicating with the lifting hole 124. After the suture needle 200 penetrates the first object to be sutured, the suture thread connected to the tail of the suture needle 200 may be separated from the suture device 100 through the first thread outlet seam 116 and the second thread outlet seam 126 through operation. The width of the first thread outlet seam 116 and the second thread outlet seam 126 may be smaller than the width of the suture needle 200, so as to prevent the suture needle 200 from falling out of the suture device 100 through the first thread outlet seam 116 and the second thread outlet 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 at 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 away from the first groove 117. During the rising process 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 has not been 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 suturing of the suturing device 100, the active member 122 can be pulled up to be separated from the first groove 117, and drive the driven member 121 to move. The height of the active member 122 rising can be less than the height of the active member 122 separating from the guide assembly 130, thereby ensuring that the active member 122 can abut against the guide assembly 130 and prevent the guide assembly 130 from falling into the first groove 117.

[0046] like Figure 3 As shown, in some embodiments, a first slope 127 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 may be formed in 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 may be closer to the suture needle 200 relative to the upper end. The geometric center of the suture needle 200 may 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 three-dimensional 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 may be of a special-shaped structure, so that the friction between the guide block 131 and the guide groove 141 can be increased, the guide assembly 130 can be prevented from being separated from the guide seat 140, and the accuracy of the movement of the guide block 131 can be improved. The end of the guide block 131 may be elastic, for example, the end of the guide block 131 may be connected to an elastic member, so as to increase the friction between the guide block 131 and the suture needle 200. The elastic member may 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 outlet 115. The suture needle 200 may pass through the needle outlet 115 and penetrate the first sutured object under the pressure of the second slope 133. Further, the guide block 131 may be formed with a cutout 132 that matches the shape of the suture needle 200. The cutout 132 may have two opposite side surfaces and a second slope 133 at the bottom. By providing the cutout 132, the suture needle 200 may be restricted from moving to the needle outlet 115 through the cutout 132, thereby preventing the suture needle 200 from deviating from the predetermined motion trajectory.

[0050] like Figure 3-Figure 4 As shown, in some embodiments, a second groove 128 matching the top shape of the active member 122 may be formed on one side of the driven member 121 close to the active member 122. When the active member 122 is pulled to the driven member 121, the top of the active member 122 may 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 driving device. For example, a winding wheel 500. The winding wheel 500 can be wound with a driving 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 grip portion 600 and a connecting portion 700. The grip 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 (such as Figure 8 The upper end of the auxiliary handle 620 (as shown in FIG. 1 ) can be pivotally mounted on the handle housing 611 via a pivot 630. The other end of the auxiliary handle 620 (as shown in FIG. 1 ) can be pivotally mounted on the handle housing 611 via a pivot 630. Figure 8 The auxiliary handle 620 (shown at the lower end) can be connected to the slider 613 through 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, so that the lifting assembly 120 can be lifted. The auxiliary handle 620 can be formed with a curved surface that fits the palm of the operator. A convex point array can be formed on the curved surface, which can apply a certain friction force to the palm, thereby facilitating the operator to perform refined 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 to the lifting assembly 120 from the grip portion 600 through the connecting portion 700.

[0055] like Figure 8 As shown, in some embodiments, a guide column 615 may be formed in the handle housing 611. The drive wire 300 may be wound around the guide column 615 and 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 column 615 may also 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 installed in the handle housing 611 and connected to the slider 613 to drive the slider 613 to return to an unactivated state without rotating the auxiliary handle 620. At the same time, the elastic member 614 may make the structure of the entire stapler more compact, and by generating an automatic rebound force, may provide the user with a more realistic use experience.

[0057] like Figure 8As shown, in some embodiments, the grip portion 600 may further include an insert 650. The insert 650 is pluggable and extends from the outside of the handle housing 611 to the guide rod 612. A third groove matching the shape of the insert 650 may be formed on the slider 613. When the slider 613 slides along the guide rod 612 to the insert 650, the insert 650 is embedded in the third groove, which can prevent the auxiliary handle 620 from continuing to rotate, so as to prevent the slider 613 from moving, thereby allowing the stapler to enter the third state of preparation. In the third state, the insert 650 prevents the slider 613 from moving, and the guide block 131 moves to a state where the suture needle 200 is squeezed but not yet pushed to move, thereby fixing the suture needle 200 and preventing the suture needle 200 from detaching from the suture device 100 during the process of moving the stapler. After the insert 650 is pulled out, the lifting assembly 120 can be continuously lifted by continuing to rotate the auxiliary handle 620, thereby entering the second state of suturing the first sutured object.

[0058] Fig. 9 A stereoscopic view of a blood vessel externalization platform according to an embodiment of the present disclosure is schematically shown. Fig.10 The side view schematically shows the application of the stapler according to the embodiment of the present disclosure in combination with the external blood vessel platform. Fig.11 A three-dimensional view of an intravascular platform according to an embodiment of the present disclosure is schematically shown. Fig.12 The side view schematically shows the application of the stapler according to the embodiment of the present disclosure in combination with the intravascular platform 900.

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

[0060] like Figure 9-10As shown, one end of the vascular external platform 800 may be formed with an external gripping end 810 for holding. The other end of the vascular external platform 800 may be in the shape of a hollow disc. The circular hole 820 in the middle may be slightly larger than the minimum diameter of the housing 110. For example, it may be 1mm-2mm larger than the minimum diameter of the housing 110. Thus, the target blood vessel may be better pulled so that it deforms to adapt to the use of the suturing device 100. Specifically, a hole may be punched in the area of ​​the first sutured object 400 to be anastomosed, or a circular piece of tissue may be cut off. 2-4 sutures are sewn into the hole, and by pulling the sutures, the edge of the hole in the anastomotic 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, the first sutured object 400 may be punctured at the same time.

[0061] like Figure 11-Figure 12 As shown, one end of the intravascular platform 900 may be formed with an internal gripping end 910 for holding. The other end of the intravascular platform 900 may be folded. 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 may 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 that allows the second secondary connecting rod 950 and the first secondary connecting rod 940 to be cross-arranged. The first tertiary connecting rod 960 may also be rotatably connected to the second tertiary connecting rod 970. The first three-stage connecting rod 960 and the second three-stage connecting rod 970 can be connected to the built-in holding end 910. The blood vessel embedded platform 900 can be recovered into a linear platform, or it can be unfolded into a quadrilateral platform. In the case of a linear platform, the blood vessel embedded platform 900 can be inserted into the blood vessel through a hole pre-punctured on the target blood vessel, and then unfolded into a quadrilateral platform to create support for the deformation of the target blood vessel.

[0062] The operator applies torque to the first tertiary connecting rod 960 and the second tertiary connecting rod 970 and transforms them, so that the intravascular platform 900 can be recovered into a linear platform or unfolded into a quadrilateral platform. When the platform is recovered into a linear platform, the operator needs to give a certain holding force to maintain the linear shape of the platform. When unfolded into a quadrilateral platform, the first tertiary connecting rod 960 and the second tertiary connecting rod 970 have the characteristics that the end faces of the holding ends can be aligned, and the shape behind them is also more regular. A locking ring can be placed externally to lock it in the form of a quadrilateral platform, which is also the conventional storage form of the intravascular platform 900. Specifically, the first sutured object 400 can be punctured first, and the intravascular platform 900 can be recovered into a linear state, so that the linear state of the platform enters the first sutured object 400 from the punctured hole to create a hollow rigid support. The anastomosis area is pressed by the lower part of the housing 110 to deform the anastomosis area on the first sutured object 400 to fit the lower part of the housing 110. When the suture needle 200 passes through the needle outlet 115, the suture needle 200 passes through the first sutured object 400. At this time, the suture device 100 and the anastomosis area of ​​the first sutured object 400 are tightly connected. Manually pressing the first sutured object 400 at the outer circle of the anastomosis area can make the suture needle 200 pass through the first sutured object 400 again.
