[Technical field]

[0001] SUTURE HOLDER FOR CARDIOVASCULAR SUTURES FIELD OF THEINVENTION This invention relates to surgical suture holders, and in particular to cardiovascular surgical suture holders for tubular snaring objects. [Background technology]

[0002] Conventional hemostatic clamps are commonly used during surgical procedures, such as cardiovascular surgery or cardiac surgery involving cardiac cannula fixation, to hold surgical sutures by clamping a rubber hose (e.g., a snare tube) through which the surgical sutures pass. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] China Design Registration No. 306042091S Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional hemostatic clamps take up a lot of space in the area adjacent to the incision opening or the thoracic surgical field. It can be difficult for surgeons to use conventional hemostatic clamps when the incision opening is relatively small or when the thoracic surgical field needs to be temporarily closed, especially when multiple conventional hemostatic clamps are required for the surgical procedure. To perform the surgical procedure using conventional hemostatic clamps, the incision opening may be made larger than necessary or the thoracic surgical field may need to remain partially closed, which may increase the risk of infection and / or prolong the patient's recovery time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A surgical suture holder according to the present invention will now be described with reference to the drawings.

[0010] The surgical suture holder according to the present invention will be described with reference to Figures 1 to 6. Here, Figure 1 is a perspective view showing one embodiment of the surgical suture holder according to the present invention, Figure 2 is an exploded perspective view showing the embodiment, Figure 3 is a schematic view showing the embodiment holding a surgical suture, Figure 4 is a schematic view showing the embodiment holding a surgical suture in a different manner, Figure 5 is a schematic view showing the embodiment holding a surgical suture in another different manner, and Figure 6 is a schematic view showing the embodiment holding a surgical suture while the surgical suture ties a cannula (C) to a patient's biological tissue (T).

[0011] As shown in Figs. 1-3, one embodiment of the surgical suture holder according to the present invention is configured to be placed in an opening of a tubular object, configured to hold a surgical suture, and extends along the axis (A) of the holder. The surgical suture holder includes an insertion section 1, a holding section 2, a winding section 3, and a cutting section 4. The tubular object can be a rubber hose used in surgery (e.g., cardiovascular surgery or cardiac surgery involving fixation of a cardiac cannula). The surgical suture has two end sections and a connecting section connecting the two end sections. The connecting section of the surgical suture extends through the biological tissue (T) of the patient, i.e., the biological tissue (T) of the patient is sutured by the connecting section of the surgical suture. The two end sections of the surgical suture can extend through the tubular object, so that both ends of the surgical suture are on one side opposite the connecting section of the tubular object.

[0012] FIG. 3 illustrates the purse string technique. First, the connecting section of the surgical suture extends into and out of the patient's biological tissue (T) along the periphery of the opening in the patient's biological tissue (T), so that the opening in the patient's biological tissue (T) is surrounded by the connecting section of the surgical suture. The two end sections of the surgical suture extend through the tubular object. Then, the two end sections of the surgical suture are pulled away from the patient's biological tissue (T) to narrow / close the opening in the patient's biological tissue (T). Then, when the surgical suture is tightened, a surgical suture holder is placed in the opening of the tubular object to hold the surgical suture.

[0013] The insertion section 1 is inserted into the opening of the tubular object and is configured to have a tapered shape that narrows toward the tubular object to facilitate insertion into the tubular object. In this embodiment, the insertion section 1 is configured to have a conical shape. In one embodiment, the insertion section 1 may have another shape as long as it narrows toward the tubular object.

[0014] The holding section 2 has a holding plate 21, in which at least one holding groove 22 and at least one groove-defining surface 23 are formed. In this embodiment, the holding section 2 has four holding grooves 22 and four groove-defining surfaces 23. The holding plate 21 is configured in a disk shape, has an outer periphery surrounding the axis (A) of the holder, and is made of an elastic material so as to be deformable. Each groove-defining surface 23 defines one holding groove 22. Each holding groove 22 is formed so as to be recessed from the outer periphery of the holding plate 21, penetrates the holding plate 21 in the extension direction of the axis (A) of the holder, and is configured so that a surgical suture can be inserted into the holding groove 22 and held in any one of the holding grooves 22. Each holding groove 22 has a groove neck portion 221 and a groove head portion 222. The groove neck 221 of each retaining groove 22 is continuous with the outer periphery of the retaining plate 21 and has a width smaller than the outer diameter of the surgical suture before deformation of the retaining plate 21. The groove head 222 of each retaining groove 22 is in spatial communication with the groove neck 221 of the retaining groove 22 and is configured to accommodate the surgical suture.

[0015] Each groove-defining surface 23 has two guide portions 231, two neck-defining portions 232, and a head-defining portion 233. The two guide portions 231 are on the outer periphery of the retaining plate 21 and are spaced apart from each other. The two neck-defining portions 232 in each groove-defining surface 23 are continuous with the two guide portions 231 in the groove-defining surface 23, and together, spaced apart from each other, define a groove neck portion 221 of one of the retaining grooves 22. The head-defining portion 233 in each groove-defining surface 23 is continuous with the two neck-defining portions 232 in the groove-defining surface 23 and defines a groove head portion 222 of one of the retaining grooves 22. The two guide portions 231 in each groove-defining surface 23 are configured to guide the surgical suture, so that the surgical suture can be easily moved into the groove neck portion 221 of one of the retaining grooves 22. That is, the surgical suture can be guided into the groove head 222 of one of the retaining grooves 22 by the guide portion 231 of each one of the groove defining surfaces 23 that defines the retaining groove 22 .

[0016] The winding section 3 is between the insertion section 1 and the holding section 2, and includes a winding portion 31, a first retaining plate 32, and a second retaining plate 33. The winding portion 31 is configured to allow a surgical suture to be wound thereon, and connects the first retaining plate 32 and the second retaining plate 33. The first retaining plate 32 is between the winding portion 31 and the insertion section 1, and the second retaining plate 33 is between the winding portion 31 and the holding section 2. The first retaining plate 32 includes a first plate body 321 and at least one first recess 322. In this embodiment, the first retaining plate 32 includes four first recesses 322. In this embodiment, the retaining plate 21 and the second retaining plate 33 are made of different materials to increase friction between the retaining plate 21 and the second retaining plate 33. In one embodiment, the retaining plate 21 and the second retaining plate 33 may be integrally formed. The first plate 321 has an outer periphery surrounding the axis (A) of the holder. Each of the first recesses 322 is recessed from the outer periphery of the first plate 321 and penetrates the first plate 321 in the extension direction of the axis (A) of the holder. The second retaining plate 33 has a second plate 331 and at least one second recess 332. The retaining plate 21 is disposed on one side of the second plate 331 of the second retaining plate 33 opposite the winding portion 31. In this embodiment, the second retaining plate 33 has four second recesses 332. The second plate 331 has an outer periphery surrounding the axis (A) of the holder. Each of the second recesses 332 is recessed from the outer periphery of the second plate 331 and penetrates the second plate 331 in the extension direction of the axis (A) of the holder, and spatially communicates with each of the retaining grooves 22 in the retaining section 2. The second recesses 332 in the second retaining plate 33 are located at positions corresponding to the retaining grooves 22 in the extension direction of the axis (A) of the holder in the second plate 331. The first recesses 322 in the first retaining plate 32 are located at positions corresponding to the retaining grooves 22 in the extension direction of the axis (A) of the holder in the first plate 321, whereby the first recesses 322 are located at positions corresponding to the second recesses 332 in the extension direction of the axis (A) of the holder.Thus, when a surgical suture is retained by one of the retaining grooves 22 , the surgical suture extends through one of the second recesses 332 and one of the first recesses 322 .

[0017] The cutting section 4 is between the insertion section 1 and the winding section 3 and has a concave surface 42 that defines a cutting recess 41. The concave surface 42 surrounds the axis (A) of the holder such that the cross-sectional area of ​​the cutting section 4 decreases and then increases as the cutting section 4 extends from the insertion section 1 to the winding section 3. When the surgical suture is held by one of the retaining grooves 22 and extends through one of the second recesses 332 and one of the first recesses 322, the surgical suture extends beyond the cutting recess 41. The configuration in which the cross-sectional area of ​​the cutting section 4 decreases and then increases as the cutting section 4 extends from the insertion section 1 to the winding section 3 causes the surgical suture to be draped over the concave surface 42 when it extends beyond the cutting recess 41.

[0018] Please note that in this embodiment, the surgical suture holder has four retaining grooves 22, four first recesses 322, and four second recesses 332. The connecting section of each surgical suture extends through the patient's biological tissue (T), and the two end sections of each surgical suture extend through the tubular object. The winding portion 31 can wind the surgical suture. When there are four surgical sutures, each surgical suture is retained by one retaining groove 22, extends through one first recess 322 and one second recess 332, and extends beyond the cutting recess 41. However, in one embodiment, the surgical suture holder may have only one retaining groove 22, one first recess 322, and one second recess 332 such that one surgical suture is retained by the retaining groove 22, extends through the first recess 322 and the second recess 332, and extends beyond the cutting recess 41. In other embodiments of the surgical suture holder, the retaining grooves 22, first recesses 322, and second recesses 332 are the same in number and may be any number other than those mentioned in the above examples (i.e., four or one). Additionally, each retaining groove 22 may hold more than one surgical suture (i.e., in this embodiment, the surgical suture holder may hold five or more surgical sutures at one time).

[0019] It should be noted that in one embodiment, the surgical suture holder can be configured to hold at least one surgical tape. When the surgical suture holder is used to hold a surgical tape, the groove neck 221 of one retaining groove 22 that holds the surgical tape has a width smaller than the width of the surgical tape before the retaining plate 21 is deformed, and the groove head 222 of one retaining groove 22 is configured to accommodate the surgical tape. In another embodiment, the surgical suture holder can be configured to hold at least one surgical tape and at least one surgical suture at a time.

[0020] Generally, a surgical suture holder is used to hold one surgical suture at a time. When using the surgical suture holder after the patient's biological tissue (T) has been stitched together by the connecting section of the surgical suture, the user pulls the two end sections of the surgical suture extending through the tubular object to increase the tension of the surgical suture. At this time, a needle holder or clamp is used to clamp the tubular object and the two end sections of the surgical suture passing through the tubular object. Then, while pulling the two end sections of the surgical suture, the user closes the opening of the tubular object with the insertion section 1 of the surgical suture holder to maintain the tension of the surgical suture stored between the opening of the tubular object and the patient's biological tissue (T). After the insertion section 1 of the surgical suture holder is securely inserted into the opening of the tubular object, the needle holder or clamp is removed. The user then pulls the two end sections of the surgical suture tighter and winds the two end sections of the surgical suture around the windings 31 of the winding section 3, so that the two end sections of the surgical suture extend beyond the cutting recess 41, span over the concave surface 42, and extend through one of the first depressions 322 in the winding section 3. The user then draws the two end sections of the surgical suture into one of the retaining grooves 22. Two guide portions 231 on one of the groove-defining surfaces 23 defining one of the retaining grooves 22 guide the two end sections of the surgical suture into the groove necks 221 of one of the retaining grooves 22. At this time, because the retaining plate 21 is made of an elastic material, the retaining plate 21 is elastically deformed, so that the two end sections of the surgical suture move in the radial direction of the retaining plate 21 through the groove neck 221 of each of the retaining grooves 22 to the groove head 222 of the retaining groove 22, and are received in the groove head 222 of the retaining groove 22. When the two end sections of the surgical suture are received in the groove head 222 of each of the retaining grooves 22, the retaining plate 21 returns to its initial state (i.e., an undeformed state).The width of the groove neck 221 of each of the retaining grooves 22 is smaller than the outer diameter of the surgical suture, so that the two end sections of the surgical suture are prevented from moving radially outward from the retaining plate 21. The two end sections of the surgical suture are thus retained by each of the retaining grooves 22. At this time, the two end sections of the surgical suture extend through each of the first recesses 322 of the second retaining plate 33. As shown in FIG. 4, it should be noted that in order to further ensure the retaining effect, after the user winds the two end sections of the surgical suture around the winding portion 31 of the winding section 3, the two end sections of the surgical suture can be pulled into another of the retaining grooves 22, so that the other of the retaining grooves 22 holds the surgical suture, and the surgical suture extends through another of the second recesses 332 located at a position corresponding to the other of the retaining grooves 22 in the extension direction of the axis (A) of the holder.

[0021] 5, it should be noted that to further ensure the retention effect, a user may wrap one end section of the surgical suture through at least any two of the retention grooves 22 (i.e., one end section of the surgical suture may be wrapped through all four of the retention grooves 22). Additionally, a user may wrap each end section of the surgical suture through at least any two of the retention grooves 22.

[0022] As shown in FIG. 6, the surgical suture holder may be used in a surgical procedure involving the fixation of a cannula. In this case, the patient's biological tissue (T) is a blood vessel, and the cannula (C) is inserted into the wound of the blood vessel. Both the cannula (C) and the wound of the blood vessel are surrounded by the connecting section of the surgical suture. When the surgical suture is pulled and tightened, the wound of the blood vessel is narrowed and the surgical suture connects the cannula (C) to the blood vessel. The surgical suture holder is then securely inserted into the opening of the tubular object, and the user can pull the end sections of the surgical suture tighter and tighten them to wind the two end sections of the surgical suture around the windings 31 of the winding section 3, and draw the two end sections of the surgical suture into one of the retaining grooves 22, respectively. Thus, the cannula (C) is fixed to the patient's biological tissue (T).

[0023] When removing the surgical suture, the cutting recess 41 and the maintained tension of the surgical suture allow the user to easily cut the two end sections of the surgical suture at a position between the first retaining plate 32 and the insertion section 1. The two end sections of the surgical suture can then be unwound from the winding portion 31 of the winding section 3 and released from the at least one retaining groove 22 that holds the two end sections of the surgical suture. The user can then discard the used end sections of the surgical suture.

[0024] In summary, the surgical suture holder according to the present invention provides a larger operating space due to the compactness of the surgical suture holder, facilitating the intended surgical operation, and allows the surgeon to have enough space for a safe operation even when performing an operation requiring multiple surgical suture holders. That is, the surgeon does not need to make the incision opening larger than necessary. Even when the operation involves a thoracotomy or the surgeon needs to temporarily close the thoracic surgical field, it is relatively easy for the surgeon to close the thoracic surgical field as a whole while leaving the surgical suture holder in the thoracic cavity, so that the risk of infection during the operation can be reduced. Furthermore, the retaining groove 22 of the retaining section 2 not only clamps the surgical suture between the opening of the tubular object and the insertion section 1 of the surgical suture holder, but also double-holds the surgical suture when it is wound around the winding section 31 and the retaining groove 22 by the surgical suture holder. This allows the surgeon to perform the operation in a smoother and safer manner, and reduces the risk of the operation.

[0025] Although numerous specific details are set forth above to facilitate a thorough understanding of the present invention, it will be apparent to one of ordinary skill in the art that one or more other embodiments may be practiced without the specific details.

[0026] Although the preferred embodiments and modified examples of the present invention have been described above, the present invention is not limited to these, and is intended to encompass all modifications and equivalent configurations as various configurations falling within the spirit and scope of the broadest interpretation.
