Description

Technical Field

[0001] The present invention relates to a vascular anastomosis device. Background Art

[0002] Vascular anastomosis technology is a major advancement in microsurgery. It can efficiently connect blood vessels and plays a key role in the failure of microsurgery repair and reconstruction. Today, in addition to traditional manual suturing, other new vascular anastomosis technologies have also flourished, such as the routine method, adhesive method, anastomosis clip method or stapler method. Among them, the effect of the stapler method has been proven to be widely used in tissues of the limbs, breasts or oral and maxillofacial areas, and can be repaired and reconstructed, allowing patients to obtain better treatment results.

[0003] However, the existing stapler method still relies on manual use of vascular clamps to turn the blood vessel wall outward 90 degrees, and then fix the turned-out blood vessel wall to the staplers in a specific order. However, this step not only relies on the skilled techniques of the doctor, but also makes it difficult to perform this step if the patient's blood vessels are hardened or brittle, and it is easy for the blood vessels to be damaged due to uneven force. In addition, even if this step is completed, it cannot ensure that the blood vessel wall has been properly fixed. Therefore, the existing manual use of staplers still has problems such as poor fixation effect, easy bleeding from the pinhole, long time consumption, or poor alignment. The existing manual method requires the two ends of the blood vessel wall to be processed separately before they can be joined, which needs to be improved. Furthermore, because it is a manual fixation, it is impossible to ensure that the fixation effect of each manual use of the stapler is consistent, so that the fixed blood vessel may fall off in the patient's body, causing additional risks in surgery.

[0004] Therefore, it is urgent to propose an improved vascular anastomosis device to eliminate or alleviate the above problems. Summary of the invention

[0005] In view of this, according to one viewpoint of the present disclosure, a vascular anastomosis device is proposed to improve the fixation effect of the vascular anastomosis device, shorten the operation time, reduce the alignment time, enhance the ease of use or enable the connection to be performed through simple steps, so that the vascular anastomosis device can play a greater role, thereby reducing the burden on surgeons, or even reducing additional risks of the operation.

[0006] Therefore, the vascular anastomosis device disclosed in the present invention includes a vascular jaw clamp unit and a first vascular fixing mechanism; wherein the vascular jaw clamp unit is provided with a vascular anastomosis ring, and the vascular anastomosis ring is sleeved on the first vascular fixing mechanism, so when operating the vascular anastomosis device, the blood vessel can be folded outward at an angle (for example, 90 degrees) and then fixed on the vascular anastomosis ring.

[0007] In addition, the first blood vessel fixing mechanism includes a first tube, a blood vessel positioning member, a second tube, a blood vessel support unit, a pusher and a third tube; wherein the first tube has a first end and a second end, and the first end is opposite to the second end, and a first opening and a first guide rail are provided on the first tube; the blood vessel positioning member is connected to the first end of the first tube. On the other hand, the blood vessel positioning member may be provided with a first protrusion at the third end relative to the first end, the blood vessel expansion member may be provided with a first concave hole, and the first concave hole may be provided corresponding to the first protrusion, but the present disclosure is not limited thereto. By moving the first tube, the first protrusion can be moved outside the first concave hole, so that the blood vessel positioning member is expanded outward to be smoothly inserted into the blood vessel; then, when the first protrusion is moved into the first concave hole again, the blood vessel can be attached and clamped on the blood vessel support unit.

[0008] Secondly, the second tube is accommodated in the first tube, the blood vessel support unit is assembled on the second tube and is arranged adjacent to the third end of the blood vessel positioning member, and the third end is opposite to the first end of the first tube, wherein the blood vessel support unit includes a blood vessel support body and a blood vessel expansion member, and the blood vessel expansion member is pivoted on the blood vessel support body. By moving the second tube, the blood vessel expansion member is pivoted to fold the blood vessel attached to the blood vessel support unit outward at an angle (for example, 90 degrees), and at the same time fix the blood vessel on the blood vessel anastomosis ring.

[0009] Furthermore, the pushing member is accommodated in the first tube member, wherein the pushing member is arranged adjacent to the second end of the first tube member. Since the pushing member is engaged in the first tube member, when the pushing member moves backward, the blood vessel positioning member can be stretched outward to be inserted into the blood vessel; the third tube member is accommodated in the pushing member and is provided with a cross bar and a guide rod, wherein the cross bar is arranged corresponding to the first opening of the first tube member, thereby allowing the cross bar to move within the range of the first opening of the first tube member, and the guide rod is arranged corresponding to the first guide rail, so that the guide rod can move along the first guide rail.

[0010] In the vascular anastomosis device of the present disclosure, the vascular jaw clamp unit may include a first part and a second part, the first part and the second part may be pivotally connected by a pivot, the vascular anastomosis ring may be arranged on the first part, and another vascular anastomosis ring may be arranged on the second part, but the present disclosure is not limited to this. In addition, the present disclosure may also include another first vascular fixing mechanism, wherein another vascular anastomosis ring may be sleeved on another first vascular fixing mechanism, but the present disclosure is not limited to this. After the two ends of the blood vessel are respectively fixed to the vascular anastomosis rings on the first part and the second part, the pivot may be pivoted to make the first part and the second part engage toward each other, so as to facilitate the anastomosis of the two ends of the blood vessel. On the other hand, since two sets of identical vascular anastomosis rings are provided at the same time, the two ends of the blood vessel can be processed synchronously and the vascular anastomosis process can be completed.

[0011] In the vascular anastomosis device of the present disclosure, the first vascular fixing mechanism may also include a fourth tube, wherein the fourth tube may be provided with a first through hole, and the cross bar may be assembled in the first through hole of the fourth tube and may protrude from the opening of the first tube, so that when the second tube moves, it can simultaneously rotate along the first through hole of the fourth tube, but the present disclosure is not limited to this.

[0012] The vascular anastomosis device of the present disclosure may further include a housing, wherein the vascular jaw clamp unit and the first vascular fixing mechanism may be accommodated in the housing, but the present disclosure is not limited thereto. In addition, the housing of the present disclosure may be provided with a second guide rail, which may be provided corresponding to the cross bar, but the present disclosure is not limited thereto, so that the second pipe member may move along the path of the second guide rail. Furthermore, the housing of the present disclosure may be provided with a third guide rail, a first protrusion may be provided on the first pipe member, and the third guide rail may be provided corresponding to the first protrusion, but the present disclosure is not limited thereto, so as to ensure that the first pipe member does not rotate relative to the housing.

[0013] In the vascular anastomosis device of the present disclosure, a base may be further included, which may be accommodated in the shell and may be provided with a clamping positioning unit, wherein the vascular jaw clamp unit may be provided corresponding to the clamping positioning unit, but the present disclosure is not limited thereto. In addition, the vascular jaw clamp unit may include a first portion and a second portion, the first portion and the second portion may be pivotally connected via a pivot, the clamping positioning unit may include a recess, and when the first portion and the second portion are clamped, the first portion and the second portion may be accommodated in the recess. When the vascular jaw clamp unit is moved by force, since the vascular jaw clamp unit abuts against the clamping positioning unit, the pivot begins to pivot, so that the first portion and the second portion are clamped toward each other, thereby completing the vascular anastomosis, but the present disclosure is not limited thereto.

[0014] The vascular anastomosis device of the present disclosure may also include a first driving member, which may be disposed on the base, wherein the vascular jaw clamp unit may be pivotally mounted on the first driving member, but the present disclosure is not limited thereto, so that the first driving member is linked to the vascular jaw clamp unit.

[0015] In the vascular anastomosis device of the present disclosure, the first driving member may be provided with a third protrusion, and the third protrusion may be provided corresponding to a first protrusion of the base, but the present disclosure is not limited thereto. When the third protrusion is engaged with the first protrusion, if the base moves forward, the first driving member may be driven to move forward at the same time, but the first driving member may only move forward relative to the base, and cannot move backward relative to the base.

[0016] The vascular anastomosis device of the present disclosure may further include a second driving member, which may be assembled in a sliding groove of the propulsion member and may be provided with a first connecting member, wherein the first connecting member may be connected to a first linkage element, but the present disclosure is not limited thereto. When the first linkage element moves, the second driving member may be linked to move, and the sliding groove provides the second driving member with an appropriate moving space.

[0017] In the vascular anastomosis device of the present disclosure, a third driving member may be further provided, which may be provided with a second protrusion, which may be provided corresponding to a sliding member, and the sliding member may be pivotally provided with a rotating element, wherein the rotating element may be provided adjacent to a first fixing member of the housing, and the rotating element may be provided corresponding to a second protrusion of the housing, and the rotating element may be provided corresponding to a fourth protrusion of the pushing member, but the present disclosure is not limited thereto. In addition, the present disclosure may further include a device body, wherein the housing may include a first fixing member and may be assembled in the device body through the first fixing member, but the present disclosure is not limited thereto. When the rotating element rotates due to contact with a second protrusion of the housing, the rotating element may engage with the fourth protrusion, thereby enabling the rotating element to drive the pushing member in a linkage manner.

[0018] In the vascular anastomosis device of the present disclosure, a fifth tube member may be further included, which may be accommodated in the device body, wherein the fifth tube member may be provided with a clamping member and an elastic element, but the present disclosure is not limited thereto. In addition, the present disclosure may further include a displacement control member, which may be accommodated in the device body, wherein the displacement control member may be provided corresponding to the clamping member, but the present disclosure is not limited thereto.

[0214] The operating mechanism of the blood vessel jaw unit 10 and the first blood vessel fixing mechanism 20 .

[0215] Figures 1 to 6 The vascular jaw clamp unit 10 and the local first vascular fixing mechanism 20 (such as Figure 7 Schematic diagram of the actuation mechanism.

[0216] like Figure 1 As shown, at this time, the vascular jaw clamp unit 10 and the first vascular fixing mechanism 20 (such as Figure 7 In the unactivated state (as shown in the figure), the first protrusion 2021 of the vascular positioning member 202 is disposed in the first recess 2073 of the vascular expansion member 2072, and the first portion 101 or the second portion 102 of the vascular jaw clamp unit 10 is sleeved outside the vascular positioning member 202.

[0217] like Figure 2 As shown, at this time, the blood vessel 80 is inserted, and the first button 5011 of the first operating unit 501 is operated. The operating mechanism of the first operating unit 501 will be described in detail below (see Fig.18 and Fig.19 As shown in the figure, the vascular positioning member 202 moves along the direction D2, and the first protrusion 2021 of the vascular positioning member 202 disengages from the first recess 2073 of the vascular expansion member 2072, causing the vascular positioning member 202 to slightly open outward and form a gap G between the third end 202a of the vascular positioning member 202 and the vascular support body 2071, so that the blood vessel 80 can be inserted into the vascular support body 2071 and accommodated in the gap G.

[0218] like Figure 3 As shown, at this time, the insertion into the blood vessel 80 is completed, and by operating the first operating unit 501 (such as Fig.18As shown in FIG. 2 ), the blood vessel positioning member 202 moves along the direction D1, and the first protrusion 2021 of the blood vessel positioning member 202 returns to the first concave hole 2073 of the blood vessel expansion member 2072, so that the gap G disappears (as shown in FIG. 2 ). Figure 2 As shown), the third end 202a of the blood vessel positioning member 202 is able to clamp the blood vessel 80.

[0219] like Figure 4 Please refer to Fig.12 At this time, the vascular jaw clamp unit 10 is in an actuated state, and the actuation mechanism of the second operating unit 502 will be described in detail below (eg Fig.18 As shown in FIG. 1 ), the vascular jaw clamp unit 10 moves along the direction D1 from the position originally set outside the vascular positioning member 202 (as shown in FIG. 1 ). Figure 3 As shown in the figure, the anastomotic ring 104 is moved to a position where it is sheathed outside the blood vessel 80, so as to facilitate the subsequent fixation of the blood vessel to the blood vessel anastomosis ring 104.

[0220] like Figure 5 Please refer to Figure 6 to Figure 7 At this time, the blood vessel 80 is in a state of being folded outwards, and the third operating unit 503 is operated. The operating mechanism of the third operating unit 503 will be described in detail below (eg Fig.18 As shown in FIG. 2 ), the blood vessel expansion member 2072 linked with the third tube 210 moves along the direction D1. Since the blood vessel expansion member 2072 is pivoted on the blood vessel support body 2071, the blood vessel expansion member 2072 can be folded outward after pivoting, so that the blood vessel 80 attached to the blood vessel expansion member 2072 is folded outward. In addition, since the blood vessel expansion member 2072 and the blood vessel positioning member 202 move synchronously along the direction D1 by a distance a, the first protrusion 2021 is still engaged with the first concave hole 2073, and the blood vessel 80 is firmly clamped.

[0221] like Figure 6 Please refer to Figure 1 At this time, the blood vessel 80 is fixed to the blood vessel anastomosis ring 104. By continuously operating the third operating unit 503 (such as Fig.18 As shown), the vascular expansion member 2072 is pivoted by the rotating shaft 2075 and moved along the direction D1 by a distance b to fix the blood vessel 80 on the vascular anastomosis ring 104, thereby completing the vascular anastomosis step.

In addition, since the third tube 210 and the fourth tube 208 can move relative to the first tube 201, the guide rod 2101 and the cross bar 2051 move to the second position S2. Fig. 9 and Fig.19 As shown, since the first button 5011 is connected to the first elastic element 5012, when the first button 5011 is not operated, the first elastic element 5012 can provide elastic force to make the guide rod 2101 and the cross bar 2051 return to the first position S1, so that the blood vessel positioning member 202 clamps the blood vessel 80. Figure 3 In more detail, by operating the first button 5011 , the guide rod 2101 and the cross bar 2051 can move back and forth between the first position S1 and the second position S2 .

Figure 5 By operating the third operating unit 503 (such as Fig.18 As shown in FIG. 2 ), the third tube 208 moves in the direction D1, thereby causing the crossbar 2051 to rotate along the first through hole 2081, so that the guide rod 2101 and the crossbar 2051 move from the first position S1 to the third position S3. When the third tube 208 continues to move in the direction D1, the crossbar 2051 moves a distance a (as shown in FIG. 2 ) along the direction D1. Figure 6 As shown in FIG. 2 ), the guide rod 2101 is engaged with the first guide rail 2012 and simultaneously pushes the first pipe 201 to move a distance a along the direction D1 (as shown in FIG. 2 ). Figure 6 As shown), and then moves from the third position S3 to the fourth position S4.

In addition, since the first protrusion 3021 disposed on the base 302 is linked with the third protrusion 3031, the first driving member 303 is also synchronously moved along the direction D1 to move the vascular jaw unit 10 to a position.

[0233] like Fig.16 Please refer to Figure 4 At this time, the blood vessel 80 is fixed to the blood vessel anastomosis ring 104, and Figure 6 and Fig.11 By operating the third operating unit 503 (such as Fig.18 As shown in FIG. 1 , the pusher 209 moves along the direction D1, so that the cross bar 2051 assembled in the second guide rail 3013 moves to the sixth position S6 and fixes the blood vessel 80 on the blood vessel anastomosis ring 104.

[0234] like Fig.17 Please refer to Fig.12 At this time, the fixed blood vessel 80 is in anastomosis state, and by operating the fourth operating unit 504 (such as Fig.18 As shown in FIG. 1 ), the first linkage element 5045 moves along the direction D2, and the second driving element 304 is linked by the first connecting member 3041, so that the second tube 205 located in the blood vessel and the first tube 201 move along the direction D2 and away from the blood vessel anastomosis ring 104 (as shown in FIG. 1 ). Figure 7 ), so that the crossbar 2051 reaches the seventh position S7; and at the same time, the first driving member 303 moves along the direction D1. Since the first part 101 and the second part 102 of the vascular jaw clamp unit 10 correspond to the clamping positioning unit 3022, the vascular jaw clamp unit 10 pivots with the pivot 103 as the pivot, and the first part 101 and the second part 102 are clamped toward each other and disposed in the recess 3023 of the base 302, thereby completing the step of anastomosis of the blood vessel 80.

Since the sixth tube 5038 is connected to the pusher 209, the pusher 209 moves along the direction D1, so that the blood vessel 80 is fixed to the blood vessel anastomosis ring 104 (as shown in FIG. Figure 5In addition, when the third gripping element 5031 is operated, since the pusher 209 continues to move along the direction D1, the engaging element 5036 will contact the displacement control element 401, and the engaging element 5036 will flip and release the tenon 50361, so that the fifth tube 5035 is not linked to the pusher 209, thereby allowing the fourth gripping element 5041 to be operated continuously (as shown in FIG. Fig. 22 On the other hand, when replacing the vascular anastomosis assembly 30 (as shown in Fig.12 As shown in FIG. 1 , the sixth elastic element 5037 resets the third gripping element 5031 and returns the tenon 50361 to its original position. In addition, in this embodiment, while operating the third gripping element 5031, the fourth gripping element 5041 is simultaneously slowly moved closer to the handle (as shown in FIG. 1 ). Fig. 22 to facilitate subsequent operations.

[0243] like Fig. 22 As shown, the fourth holding element 5041 is operated to move along the direction D2, and the ninth fixing member 5050 assembled in the eleventh through hole 50411 is rotated as a pivot, so that the tooth structure 50413 on the fourth holding element 5041 is engaged with the first gear 5042, and the tooth structure 50413 moves along the direction D1 (if observed from the perspective of the figure, it is a clockwise rotation), which links the first gear 5042, the second gear 5043, the third gear 5044 and the fourth gear 5051 to rotate synchronously along the direction D2 (if observed from the perspective of the figure, it is a counterclockwise rotation), thereby driving the first linkage element 5045 to move along the direction D2, and driving the second linkage element 5046 to move along the direction D1, so as to achieve the purpose of anastomosis of the blood vessel 80. Since the fourth gripping element 5041 needs to be actuated back and forth multiple times, when the fourth gripping element 5041 moves along the direction D2 (i.e., when the fourth gripping element 5041 is operated), the first gear 5042 can rotate; and when the fourth gripping element 5041 moves along the direction D1 (i.e., when the fourth gripping element 5041 is released), the first gear 5042 does not rotate. In addition, since the first locking element 50471 is meshed with the second gear 5043, and the fourth gear 5051 is meshed with the second locking element 5052, when the release assembly 60 is not operated, the first gear 5042, the second gear 5043, and the third gear 5044 are only allowed to rotate in one direction, so that the fourth gripping element 5041 can be actuated back and forth multiple times, so that the two vascular anastomosis rings 104 can be slowly combined under visual observation to complete the anastomosis of the blood vessels 80 (such as Fig.17 The fourth gripping element 5041 is pressed to the bottom, thereby loosening the first linkage element 5045 and the first connecting member 3041. After the anastomosed blood vessel 80 is visually separated from the vascular anastomosis assembly 30 from above the recess 3023, the vascular anastomosis assembly 30 can be removed by pressing the third button 4021 (as shown). Fig.12). When operating the release assembly 60, by pressing the second button 601, the fifth fixing seat 50474 moves upward, and the adjustment element 50472 can move upward, so that the first locking element 50471 is loosened and does not mesh with the second gear 5043, allowing the first gear 5042, the second gear 5043 and the third gear 5044 to be restored to the state before the fourth gripping element 5041 is not operated, and the second gripping element 5021, the third gripping element 5031 and the fourth gripping element 5041 are released to reset. Therefore, the first linking element 5045 and the second linking element 5046 connected to the seventh elastic element 5048 and the eighth elastic element 5049 are restored to the state before the fourth gripping element 5041 is not operated, and a new blood vessel anastomosis assembly 30 can be connected to anastomose another blood vessel.

[0244] In summary, by using the vascular anastomosis device disclosed in the present invention, the fixation effect of vascular anastomosis can be effectively improved, the operation time can be shortened, the convenience can be improved, or the connection can be performed through simple steps, which has the effect of reducing the burden on surgeons or reducing additional risks of surgery.

[0245] Although the present disclosure has been described through a number of embodiments, it should be understood that many other possible modifications and variations may be made without departing from the spirit of the present disclosure and the scope of the claims.
