Description

Technical Field

[0001] The invention relates to a surgical suture fixer, in particular to a cardiovascular surgical suture fixer used for a tubular snaring object. Background Art

[0002] During surgery (e.g., cardiovascular surgery or heart surgery involving cardiac cannulation), conventional hemostats are often used to secure surgical sutures by clamping the rubber hose (snaring tube) through which the surgical sutures extend. However, conventional hemostats take up a lot of space near the surgical incision or chest surgical area.

[0003] If the surgical incision is relatively small or the chest surgical area needs to be temporarily closed, it may be difficult for the surgeon to use traditional hemostats, especially when the surgery involves multiple traditional hemostats. In order to perform the surgery with traditional hemostats, the surgeon may have to make the surgical incision larger than necessary or keep the chest surgical area partially closed, which may result in a higher risk of infection or longer recovery time for the patient. Summary of the invention

[0004] An object of the present invention is to provide a surgical suture fixator that can improve at least one problem in the prior art.

[0005] In some embodiments, the surgical suture fixer of the present invention is suitable for being arranged at the opening of a sleeve, and is suitable for fixing at least one surgical suture passing through the opening of the sleeve. The surgical suture fixer extends along the axis of the fixer and has an insertion section and a fixing section. The insertion section is suitable for being inserted into the opening of the sleeve and gradually becomes thinner toward the sleeve. The fixing section has a fixing plate whose periphery surrounds the axis of the fixer, and at least one fixing groove is formed concavely from the periphery of the fixing plate and penetrates the fixing plate along the extension direction of the axis of the fixer, and the at least one fixing groove is provided for the at least one surgical suture to be inserted into so as to fix the at least one surgical suture.

[0006] In some embodiments, the surgical suture fixer also has a winding segment located between the insertion segment BCPI-240030 Page 2 / 9 and the fixing segment, the winding segment having a winding portion suitable for winding the at least one surgical suture, and a first stopper located between the winding portion and the insertion segment, the first stopper having a first stopper body with a periphery surrounding the axis of the fixer, and at least one first recess formed concavely from the periphery of the first stopper body and penetrating the first stopper body along the axis of the fixer, the at least one first recess being used for passing the at least one surgical suture fixed by the at least one fixing groove of the fixing segment.

[0007] In some embodiments, the winding segment also has a second stop plate located between the winding portion and the fixed segment, the second stop plate having a second stop plate body with a periphery surrounding the axis of the fixer, and at least one second recess formed concavely from the periphery of the second stop plate body and penetrating the second stop plate body along the extension direction of the axis of the fixer, the at least one second recess being used for passing the at least one surgical suture fixed by the at least one fixing groove of the fixed segment.

[0008] In some implementations, the fixing plate is made of an elastic material, and the fixing plate is disposed on the second stopping plate body of the second stopping plate.

[0009] In some embodiments, the at least one fixing groove has a groove neck portion connected to the periphery of the fixing plate, and a groove head portion connected to the groove neck portion and suitable for accommodating the at least one surgical suture, and the width of the groove neck portion is smaller than the diameter of the at least one surgical suture before the fixing plate is deformed.

[0010] In some implementations, the material of the fixing plate is different from the material of the second stopping plate.

[0011] In some embodiments, the at least one fixing groove includes a plurality of the fixing grooves, the at least one first recess of the first stop plate includes a plurality of the first recesses whose positions along the extension direction of the axis of the fixer respectively correspond to the fixing grooves, and the at least one second recess of the second stop plate includes a plurality of the second recesses whose positions along the extension direction of the axis of the fixer respectively correspond to the fixing grooves.

[0012] In some embodiments, the surgical suture fixator further has a wire cutting segment located between the insertion segment and the winding segment, the wire cutting segment having a concave surface defining a wire cutting groove, and when the at least one surgical suture spans the wire cutting groove, the at least one surgical suture is suspended relative to the concave surface.

[0013] In some embodiments, the concave surface of the wire cutting segment surrounds the axis of the fixture, so that the cross-sectional area of ​​the wire cutting segment is from adjacent to the insertion segment to adjacent to the winding segment.

[0014] First decrease and then increase.

[0015] In some embodiments, the fixing section also has at least one groove defining surface that defines the at least one fixing groove, and the at least one groove defining surface has two guide portions located at the periphery of the fixing plate and spaced apart from each other, and the two guide portions are used to guide the at least one surgical suture into the at least one fixing groove.

[0025] See also Figures 1 to 3 An embodiment of the surgical suture fixer of the present invention is suitable for being arranged in a sleeve having an opening, and is suitable for fixing a surgical suture passing through the opening of the sleeve, and the surgical suture fixer extends along a fixer axis A. The surgical suture fixer has an insertion section 1, a fixing section 2, a winding section 3, and a cutting section 4. BCPI-240030 Page 4 / 9

[0026] The sleeve can be, for example, a rubber hose used in surgery (e.g., cardiovascular surgery or heart surgery involving heart bypass cannulation). The surgical suture has two end portions and an interconnection portion interconnecting the two end portions. The interconnection portion of the surgical suture can extend through a patient's body tissue T, wherein the patient's body tissue T can be sutured by the interconnection portion of the surgical suture. The two end portions of the surgical suture can extend through the sleeve so that the two end portions of the surgical suture are located on a side of the sleeve opposite to the interconnection portion.

[0027] Figure 3 A purse-string suturing technique is shown. First, the interconnecting portion of the surgical suture extends along an edge of an opening of the patient's body tissue T and enters and exits the patient's body tissue T, so that the opening of the patient's body tissue T is surrounded by the interconnecting portion of the surgical suture. The two end portions of the surgical suture extend through the sleeve. Then, the two end portions of the surgical suture are pulled away from the body tissue T to narrow / close the opening of the patient's body tissue T. Thereafter, when the surgical suture is tightened, the surgical suture fixer is set on the opening of the sleeve to fix the surgical suture.

[0028] The insertion section 1 is adapted to be inserted into the opening of the cannula and tapers toward the cannula to facilitate insertion of the cannula. In this embodiment, the insertion section 1 is configured as a cone. In an embodiment, the insertion section 1 can have different shapes, as long as the insertion section 1 tapers toward the cannula.

[0029] The fixing section 2 has a fixing plate 21, and at least one fixing groove 22 and at least one groove defining surface 23 formed on the fixing plate 21. In this embodiment, the fixing section 2 has four fixing grooves 22 and four groove defining surfaces 23. The fixing plate 21 is configured in a disc shape, and its periphery surrounds the fixture axis A, and is made of elastic material so that the fixing plate 21 can be deformed. Each groove defining surface 23 defines a corresponding fixing groove 22. Each fixing groove 22 is recessed from the periphery of the fixing plate 21 and penetrates the fixing plate 21 along the extension direction of the fixture axis A, and is suitable for the surgical suture to be inserted, so that the surgical suture can be fixed by any fixing groove 22. Each fixing groove 22 has a groove neck 221 and a groove head 222. The groove neck 221 of each fixing groove 22 is connected to the periphery of the fixing plate 21, and has a width smaller than the line diameter of the surgical suture before the fixing plate 21 is deformed. The slot head 222 of each of the fixing slots 22 is connected to the slot neck 221 of the fixing slot 22 and is suitable for accommodating BCPI-240030 Page 5 / 9

[0030] The surgical suture.

[0031] Each of the slot defining surfaces 23 has two guide portions 231, two neck defining portions 232, and a head defining portion 233. The two guide portions 231 are located at the periphery of the fixing plate 21 and are spaced apart from each other. The two neck defining portions 232 of each of the slot defining surfaces 23 are respectively connected to the two guide portions 231 of the slot defining surface 23, and the two neck defining portions 232 are spaced apart from each other to jointly define the slot neck portion 221 of the corresponding fixing slot 22. The head defining portion 233 of each of the slot defining surfaces 23 is interconnected with the two neck defining portions 232 of the slot defining surface 23, and defines the slot head portion 222 of the corresponding fixing slot 22. The guide portions 231 of each of the slot defining surfaces 23 are suitable for guiding the surgical suture, so that the surgical suture can be easily moved into the slot neck portion 221 of the corresponding fixing slot 22. Furthermore, the surgical suture may be guided into the slot head 222 of the fixing slot 22 through the guide portion 231 of the corresponding slot definition surface 23 that defines the fixing slot 22 .

[0032] The winding section 3 is located between the insertion section 1 and the fixing section 2, and includes a winding portion 31, a first stopper 32, and a second stopper 33. The winding portion 31 is suitable for winding the surgical suture, and is connected between the first stopper 32 and the second stopper 33. The first stopper 32 is located between the winding portion 31 and the insertion section 1, and the second stopper 33 is located between the winding portion 31 and the fixing section 2. The first stopper 32 has a first stopper body 321 and at least one first notch 322. In this embodiment, the first stopper 32 has four first notches 322. In this embodiment, the fixing plate 21 and the second stopper 33 are made of different materials to increase the friction between the fixing plate 21 and the second stopper 33. In one embodiment, the fixing plate 21 and the second stopper 33 can be integrally formed. The periphery of the first stopper body 321 surrounds the fixture axis A. Each of the first notches 322 is formed concavely from the periphery of the first stopper body 321, and penetrates the first stopper body 321 along the extension direction of the fixture axis A. The second stopper 33 has a second stopper body 331 and at least one second notch 332. The fixing plate 21 is disposed on the side of the second stopper body 331 of the second stopper plate 33 opposite to the winding portion 31. In this embodiment, the second stopper plate 33 has four second notches 332. The periphery of the second stopper body 331 surrounds the fixture axis A. Each of the second notches 332 is formed concavely from the periphery of the second stopper body 331, and penetrates the second stopper body 331 along the extension direction of the fixture axis A, and is communicated with the corresponding fixing groove 22 of the fixing BCPI-240030 Page 6 / 9 Section 2. The positions of the second notches 332 of the second stopper plate 33 correspond to the positions of the fixing grooves 22 in the extending direction of the fixture axis A. The positions of the first notches 322 of the first stopper plate 32 correspond to the positions of the fixing grooves 22 in the extending direction of the fixture axis A, so that the positions of the first notches 322 correspond to the positions of the second notches 332 in the extending direction of the fixture axis A. Therefore, when the surgical suture is fixed by one of the fixing grooves 22, the surgical suture extends through a corresponding one of the second notches 332 and a corresponding one of the first notches 322.

[0033] The wire cutting segment 4 is located between the insertion segment 1 and the winding segment 3, and has a concave surface 42 defining a wire cutting groove 41. The concave surface 42 surrounds the fixture axis A, so that the cross-sectional area of ​​the wire cutting segment 4 first decreases and then increases from the position adjacent to the insertion segment 1 to the position adjacent to the winding segment 3. When the surgical suture is fixed by one of the fixing grooves 22 and extends through the corresponding second notch 332, the surgical suture extends across the wire cutting groove 41. Since the cross-sectional area of ​​the wire cutting segment 4 first decreases and then increases from the position adjacent to the insertion segment 1 to the position adjacent to the winding segment 3, when the surgical suture extends across the wire cutting groove 41, the surgical suture is suspended relative to the concave surface 42.

[0034] It is worth noting that in the present embodiment, the surgical suture fixer has four fixing grooves 22, four first notches 322 and four second notches 332. The interconnected portion of the surgical suture extends through the patient's body tissue T, and the two end portions of the surgical suture extend through the sleeve. The winding portion 31 can be wound by the surgical suture. When there are four surgical sutures, each of the surgical sutures is fixed by the corresponding fixing groove 22, extends through the corresponding first notch 322 and the second notch 332, and extends across the cutting groove 41. However, in one embodiment, the surgical suture fixer may have only one fixing groove 22, one first notch 322 and one second notch 332, so that one surgical suture is fixed by the fixing groove 22, extends through the first notch 322 and the second notch 332, and extends across the cutting groove 41. In another embodiment of the surgical suture anchor, the number of the fixing grooves 22, the first notch 322 and the second notch 332 is the same, which can be any number other than the number mentioned in the above example (i.e., four or one). In addition, each of the fixing grooves 22 can also fix more than one surgical suture (i.e., in the embodiment, the surgical suture anchor can fix more than four surgical sutures at a time).

[0035] Wire).

[0036] It is worth noting that, in one embodiment, the surgical suture fixer can be used to fix at least one surgical tape. When the surgical suture fixer is used to fix the surgical tape, the width of the groove neck 221 of one of the fixing grooves 22 for fixing the surgical tape is smaller than the width of the surgical tape before the fixing plate 21 is deformed. The groove head 222 of one of the fixing grooves 22 is suitable for accommodating the surgical tape. In another embodiment, the surgical suture fixer can be used to fix at least one surgical tape and at least one surgical suture at a time.

[0037] Typically, the surgical suture fixer is used to fix one surgical suture at a time. When the surgical suture fixer is used after suturing the patient's body tissue T through the interconnected portion of the surgical suture, the user tightens the end portion of the surgical suture extending through the cannula to increase the tension of the surgical suture. At this time, a needle holder or a clamp is used to clamp the cannula and the end portion of the surgical suture passing through the cannula. Then, while tightening the end portion of the surgical suture, the user plugs the opening of the cannula with the insertion section 1 of the surgical suture fixer to maintain the tension of the surgical suture between the opening of the cannula and the patient's body tissue T. After the insertion section 1 of the surgical suture fixer is firmly inserted into the opening of the cannula, the needle holder or the clamp is removed. After that, the user can also tighten the end portion of the surgical suture and wind the end portion of the surgical suture around the winding portion 31 of the winding segment 3, so that the end portion of the surgical suture extends across the thread cutting groove 41 and is suspended relative to the concave surface 42, and extends through one of the first notches 322 of the winding segment 3. Then, the user inserts the end portion of the surgical suture into a corresponding one of the fixing grooves 22. In this process, the guide portion 231 of the corresponding groove definition surface 23 defining the fixing groove 22 guides the end portion of the surgical suture into the groove neck 221 of the fixing groove 22. At this time, since the fixing plate 21 is made of elastic material, the fixing plate 21 undergoes elastic deformation, so that the end portion of the surgical suture can pass through the groove neck 221 of the fixing groove 22, and move toward the groove head 222 of the fixing groove 22 along the radial direction of the fixing plate 21, and be accommodated in the groove head 222 of the fixing groove 22. When the end portion of the surgical suture is accommodated in the groove head 222 of the fixing groove 22, the fixing plate 21 returns to its initial state (i.e., the fixing plate 21 is not deformed). Since the width of the groove neck 221 of each fixing groove 22 is smaller than the wire diameter of the surgical suture, the end portion of the surgical suture can be prevented from moving radially outward from the fixing plate 21. In this way, the end portion of the surgical suture is fixed by a corresponding one of the fixing grooves 22. At this time, the end portion of the surgical suture extends through a corresponding one of the second recesses 332 of the second stop plate 33. See further Figure 4 It should be noted that in order to further ensure the fixing effect, after the user wraps the end portion of the surgical suture around the winding portion 31 of the winding segment 3, the user can insert the end portion of the surgical suture into the other fixing groove 22 so that the other fixing groove 22 fixes the surgical suture. At this time, the surgical suture extends through the other second recess 332, and the position of the other second recess 332 corresponds to the position of the other fixing groove 22 in the extension direction of the fixer axis A.

[0038] Further reading Figure 5 It is worth noting that, in order to further ensure the effectiveness of fixation, the user can wrap one of the end portions of the surgical suture around at least any two of the fixing grooves 22 (i.e., one of the end portions of the surgical suture can be wrapped around all four fixing grooves 22). In addition, the user can wrap each end portion of the surgical suture around at least any two fixing grooves 22.

[0039] Further reading Figure 6 , the surgical suture fixer can also be used in surgeries involving cannula fixation. In this case, the patient's body tissue T is a blood vessel, and a cannula C is inserted into the surgical incision of the blood vessel. The cannula C and the surgical incision of the blood vessel are both surrounded by the interconnected portion of the surgical suture. When the surgical suture is pulled and tightened, the surgical incision of the blood vessel narrows, and the surgical suture positions the cannula C on the blood vessel. Then, the surgical suture fixer is firmly inserted into the opening of the cannula so that the user further tightens the end portion of the surgical suture, wraps the end portion of the surgical suture around the winding portion 31 of the winding segment 3, and snaps the end portion of the surgical suture into a corresponding one of the fixing grooves 22. Therefore, the cannula C is fixed to the patient's body tissue T.

[0040] Since the tension of the surgical suture is maintained, when removing the surgical suture, the user can easily cut the end portion of the surgical suture at a position between the first stopper plate 32 and the insertion section 1 through the thread cutting groove 41. Then, the end portion of the surgical suture is unwound from the winding portion 31 of the winding section 3 and released from the at least one fixing groove 22 that fixes the end portion of the surgical suture. Then, the user can discard the used end portion of the surgical suture.

[0041] In summary, the smaller size of the surgical suture fixator provides additional surgical space to facilitate the intended surgical operation, and the surgeon needs more surgical sutures when multiple BCPI-240030 Page 9 / 9

[0042] When performing surgery without the surgical suture fixer, there is still enough room to complete the surgery safely. Thereby, the surgeon does not need to make an incision larger than necessary on the patient. When it comes to open-chest surgery, when the surgeon must temporarily close the chest surgical area, the surgeon can relatively easily completely close the chest surgical area and leave the surgical suture fixer in the chest cavity at the same time, thereby reducing the risk of infection during surgery. In addition, by virtue of the fixing groove 22, the surgical suture is not only clamped between the opening of the sleeve and the insertion section 1 of the surgical suture fixer, but when the surgical suture is wound around the winding portion 31 and the fixing groove 22, the surgical suture is doubly fixed by the surgical suture fixer. Therefore, the surgeon can perform the operation more smoothly and safely, and reduce the risk of surgery.
