Description

Technical Field

[0001] This application relates to the field of medical device assistive technology, specifically to a suture tensioning device and an interventional medical system. Background Technology

[0002] Interventional devices are temporary medical tools that enter the body through natural cavities or minimally invasive incisions for diagnosis or treatment. They are characterized by minimal invasiveness, precision, and reversibility, and aim to assist in treatment and disease control.

[0003] In interventional medical procedures, wounds at the site of lesions within the patient's body often require internal suturing. After the wound tissue is sutured, excess sutures are tightened and cut. However, if the sutures are not tensioned before tightening, it will affect the adhesion of the sutured tissue and may even lead to suturing failure. Therefore, suture tension is crucial. In current techniques, excess sutures are often pulled manually by the surgeon after suturing, resulting in significant differences in tension between each suture. Because some sutures are tightened and cut while not fully tensioned, the tissue cannot adhere effectively, and may even lead to surgical failure. Utility Model Content

[0004] The main objective of this application is to provide a suture tensioning device and an interventional medical system to solve the problem of suture tensioning difficulties in the prior art.

[0005] On one hand, this application provides a suture tensioning device, the suture tensioning device comprising:

[0011] Furthermore, when the rotating clamping member is a split structure, one of the first rotating member and the second rotating member is configured to form a threaded hole, and the other of the first rotating member and the second rotating member is configured to form a threaded post. The threaded post is threadedly connected in the threaded hole, so that the first rotating member and the second rotating member are threadedly connected and close to each other to clamp at least one end of a suture.

[0012] Alternatively, if the rotating clamp is a split structure, one of the first rotating member and the second rotating member is configured to form a insertion hole, and the other of the first rotating member and the second rotating member is configured to form a insertion part, which is inserted into the insertion hole so that the first rotating member and the second rotating member are limited to be inserted and close to each other to clamp at least one end of a thread.

[0013] Furthermore, the first rotating member is rotatably connected to the mounting assembly, and the first rotating member forms the limiting abutment portion and the threaded hole, while the second rotating member forms the threaded post;

[0014] The first rotating component has a first clamping surface and a first annular inclined surface. The opening end of the threaded hole is located on the first clamping surface. The first annular inclined surface is obliquely outward away from the mounting assembly and is connected to the outer edge of the first clamping surface.

[0015] The second rotating member has a second clamping surface and a second annular inclined surface. The threaded post protrudes outward from the second clamping surface, and the second annular inclined surface faces outward at an angle toward the mounting assembly and connects with the outer edge of the second clamping surface.

[0016] The first rotating member is threadedly connected to the second rotating member so that the first clamping surface and the second clamping surface approach each other and clamp at least one end of a suture, and the first ring bevel and the second ring bevel approach each other to form a winding groove, which is used to receive the clamped suture during the rotation of the rotating clamp relative to the mounting assembly.

[0017] Furthermore, the limiting abutment portion includes a plurality of limiting protrusions, which are spaced apart from each other so that a limiting groove is formed between adjacent protrusions;

[0018] Wherein, the limiting abutment portion is located at the end of the first rotating member away from the first clamping surface, or the limiting abutment portion is located on the outer periphery of the end of the first rotating member away from the first clamping surface;

[0019] And / or, the number of the limiting grooves is greater than or equal to the number of the elastic limiting members.

[0020] Furthermore, the elastic limiting member is a positioning bead screw, the positioning bead of the positioning bead screw can extend into the limiting groove to limit the rotation of the rotating clamping member, and the screw of the positioning bead can be removed from the limiting groove to release the restriction on the rotating clamping member;

[0021] The tensioning assembly further includes a connecting plate, and a plurality of positioning ball screws are threadedly connected to the connecting plate, with the positioning balls of each positioning ball screw facing the limiting abutment portion; or, the positioning ball screws are threadedly connected to the mounting assembly, with the positioning balls of each positioning ball screw facing the limiting abutment portion.

[0022] Furthermore, the first rotating member includes a first segment and a second segment, the end of the first segment opposite to the second segment is the first clamping surface, and the end of the second segment opposite to the first segment is configured to form the limiting abutment portion;

[0023] The mounting assembly includes a first mounting plate, a second mounting plate, and a plurality of fasteners. The first mounting plate and the second mounting plate are connected by the plurality of fasteners and are configured to form a plurality of mounting cavities.

[0024] In this configuration, at least one of the fixing members passes sequentially through the first mounting plate, a connecting plate, and the second mounting plate. The elastic limiting member is connected to the connecting plate. The first segment extends at least partially out of the second mounting plate, and the second segment is confined within the mounting cavity and elastically abuts against the elastic limiting member.

[0025] Furthermore, both ends of each suture are clamped by the same rotating clamp, or both ends of each suture are clamped by any two rotating clamps respectively;

[0030] In the suture tensioning device of this application, by providing at least one tensioning component on the mounting assembly, and by rotatably connecting the rotating clamping member of the tensioning component to the mounting assembly, and by elastically abutting the limiting abutment portion of the rotating clamping member against the elastic limiting member, the rotating clamping member clamps one or both ends of the suture. Furthermore, when the rotating clamping member is rotated, the suture clamped by the rotating clamping member gradually winds around the rotating clamping member, and the elastic limiting member provides resistance to the rotating clamping member. The elastic restraint of the rotating clamp allows the surgeon to judge the tension of the suture in real time. After the suture is tensioned, the elastic restraint limits the rotating clamp, so that the suture held by the rotating clamp is maintained at its current tension. The surgeon can also tension the sutures held by other rotating clamps, thus facilitating the tension of all sutures and controlling the tension of multiple sutures to be basically the same. This ensures that the sutured tissue can be effectively adhered, ensuring the smooth completion of the operation and the rapid healing of the sutured tissue. Attached Figure Description

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0047] Please see Figure 1-2 As shown, in one aspect, this application provides a suture tensioning device 100, which includes a mounting assembly 10 and at least one tensioning assembly 20. The at least one tensioning assembly 20 is connected to the mounting assembly 10 and is used to tension at least one end of a suture 200.

[0048] In an embodiment of this application, the mounting assembly 10 is provided with a tensioning assembly 20, which is used to clamp both ends of all the sutures 200 together and rotate relative to the mounting assembly 10 to tension all the clamped sutures 200.

[0049] In the embodiments of this application, the mounting assembly 10 is provided with a plurality of tensioning assemblies 20, each tensioning assembly 20 being used to clamp one end of at least one suture 200 and rotate relative to the mounting assembly 10 to tension the clamped suture 200.

[0050] Please see Figure 3-6 As shown, each of the tensioning components 20 includes a rotating clamping member 21 and at least one elastic limiting member 22. The rotating clamping member 21 is rotatably connected to the mounting component 10 and can clamp at least one end of a stitch 200. Each of the rotating clamping members 21 is configured to form a limiting abutment portion 21111. At least one of the elastic limiting members 22 is connected to the mounting component 10 and elastically abuts against the limiting abutment portion 21111.

[0051] In the embodiments of this application, by providing a plurality of tensioning components 20 on the mounting assembly 10, and by rotatably connecting the rotating clamping member 21 in each tensioning component 20 to the mounting assembly 10, and by elastically abutting the limiting abutment portion 21111 of each rotating clamping member 21 against the elastic limiting member 22, each rotating clamping member 21 clamps one or both ends of a thread 200, and when rotating the rotating clamping member 21, the thread 200 clamped by the rotating clamping member 21 can be gradually wound around the rotating clamping member 21, and at the elastic limiting member... Under the elastic restraint and limiting of the rotating clamp 21, the surgeon can judge the tension of the suture 200 in real time. After the suture 200 is tensioned, the elastic limiting member 22 limits the rotating clamp 21 so that the suture 200 held by the rotating clamp 21 is kept in the current tension state, and the sutures 200 held by other rotating clamps 21 are tensioned. This allows the surgeon to tension the sutures 200 one by one and control the tension of multiple sutures 200 to be basically the same, thereby ensuring that the sutured tissue can be effectively adhered, ensuring the smooth completion of the operation, and the rapid healing of the sutured tissue.

[0052] Furthermore, when suturing tissues inside the body, one end of a suture 200 is typically inserted into the patient's body for suturing, and then extended out of the patient's body after suturing. Therefore, both ends of the suture 200 extend out of the patient's body. Thus, each of the aforementioned rotating clamping members 21 can clamp one end of each suture 200, and the two ends of a suture 200 are clamped separately through the rotating clamping members 21 corresponding to the two tensioning components 20. Then, one of the rotating clamping members 21 is rotated to allow the rotation... One end of the suture 200 clamped by the clamping member 21 is wound around the rotating clamping member 21 until the other end of the suture 200 is seen to be taut, thus completing the tensioning of both ends of the suture 200. Alternatively, the two ends of a suture 200 can be clamped simultaneously by the rotating clamping member 21, and then the rotating clamping member 21 can be rotated so that the two ends of the suture 200 are simultaneously wound around the rotating clamping member 21 until the two ends of the suture 200 are adaptively tensioned and the tissue through which it passes is tightened, thus completing the tensioning of the suture 200.

[0053] In the embodiments of this application, please refer to Figure 3-6As shown, the rotating clamping member 21 has a split structure and includes a first rotating member 211 and a second rotating member 212. The first rotating member 211 and the second rotating member 212 are connected to each other to clamp at least one end of a thread 200, and one of the first rotating member 211 and the second rotating member 212 is rotatably connected to the mounting assembly 10 and forms the limiting abutment portion 21111. Therefore, by controlling the first rotating member 211 and the second rotating member 212 to move closer to each other, a thread 200 can be clamped so that the clamped thread 200 can rotate synchronously with the first rotating member 211 and the second rotating member 212, thereby winding at least one end of the thread 200 onto the rotating clamping member 21 under the rotation of the first rotating member 211 and the second rotating member 212 until the clamped thread 200 is wound into a taut state.

[0054] In the embodiments of this application, please refer to Figure 6-7 As shown, when the rotating clamping member 21 has a split structure, one of the first rotating member 211 and the second rotating member 212 is configured to form a threaded hole 21114, and the other of the first rotating member 211 and the second rotating member 212 is configured to form a threaded post 2121. The threaded post 2121 is threadedly connected to the threaded hole 21114, so that the first rotating member 211 and the second rotating member 212 are threadedly connected and close to each other to clamp at least one end of a thread 200. When the first rotating member 211 and the second rotating member 212 clamp one end of a thread 200, rotating at least one of the first rotating member 211 and the second rotating member 212 can cause the first rotating member 211 and the second rotating member 212 to rotate synchronously to wind at least one end of the clamped thread 200 onto the rotating clamping member 21.

[0055] Furthermore, the first rotating member 211 is rotatably connected to the mounting assembly 10, and the first rotating member 211 forms the limiting abutment portion 21111 and the threaded hole 21114, while the second rotating member 212 forms the threaded post 2121.

[0056] Please refer to Figure 7-9As shown, the first rotating member 211 has a first clamping surface 21115 and a first annular inclined surface 21116. The opening end of the threaded hole 21114 is located on the first clamping surface 21115. The first annular inclined surface 21116 is obliquely outward away from the mounting assembly 10 and is connected to the outer edge of the first clamping surface 21115. The second rotating member 212 has a second clamping surface 2122 and a second annular inclined surface 2123. The threaded post 2121 protrudes outward from the second clamping surface 2122. The second annular inclined surface 2123 is obliquely outward toward the mounting assembly 10 and is connected to the outer edge of the second clamping surface 2122.

[0057] When the first rotating member 211 and the second rotating member 212 are threadedly connected and close to each other, the first clamping surface 21115 and the second clamping surface 2122 approach each other and clamp at least one end of a thread 200, thereby clamping at least one end of the thread 200. The first annular inclined surface 21116 and the second annular inclined surface 2123 approach each other to form a winding groove 213. During the rotation of the rotating clamping member 21 relative to the mounting assembly 10, the winding groove 213 is used to receive the clamped thread. 200, so that the suture 200 wound on the rotating clamp 21 is located in the winding groove 213. The winding groove 213 is formed by setting the first ring inclined surface 21116 and the second ring inclined surface 2123, so that the suture 200 wound in the winding groove 213 can be more effectively tensioned on the rotating clamp 21 under the limiting and guiding action of the first ring inclined surface 21116 and the second ring inclined surface 2123, thereby avoiding the phenomenon of the suture 200 not being tensioned due to the suture 200 retraction.

[0058] In the embodiments of this application, please refer to Figure 6-9 As shown, when the rotating clamping member 21 has a split structure, one of the first rotating member 211 and the second rotating member 212 has a insertion hole, and the other of the first rotating member 211 and the second rotating member 212 has an insertion part. The insertion part is inserted into the insertion hole so that the first rotating member 211 and the second rotating member 212 are limited to be inserted and close to each other to clamp at least one end of a thread 200, so that the clamped thread 200 can rotate synchronously with the first rotating member 211 and the second rotating member 212, thereby winding at least one end of the thread 200 onto the rotating clamping member 21 under the rotation of the first rotating member 211 and the second rotating member 212 until the clamped thread 200 is wound into a taut state.

[0059] In the embodiments of this application, please refer to Figure 8As shown, the limiting abutment portion 21111 includes a plurality of limiting protrusions 21112, which are spaced apart from each other so that a limiting groove 21113 is formed between adjacent limiting protrusions 21112.

[0060] The limiting abutment portion 21111 is located at the end of the first rotating member 211 facing away from the first clamping surface 21115. A plurality of limiting protrusions 21112 extend radially along the first rotating member 211, forming a limiting groove 21113 between adjacent limiting protrusions 21112. At least one elastic limiting member 22 is connected to the mounting assembly 10 directly opposite the limiting abutment portion 21111. When the elastic limiting member 22 elastically abuts against the limiting groove 21113, the rotating clamping member 21 is limited on the mounting assembly 10. As the rotating clamping member 21 continues to rotate, the elastic limiting member 22 elastically contracts to exit the limiting groove 21113. When the rotating clamping member 21 tensions the clamped thread 200, the elastic limiting member 22 elastically abuts against the corresponding limiting groove 21113, thereby limiting the rotating clamping member 21.

[0061] Alternatively, the limiting abutment portion 21111 is located on the outer periphery of the end of the first rotating member 211 away from the first clamping surface 21115. That is, the limiting groove 21113 is distributed on the outer periphery of the first rotating member. The elastic limiting member 22 is connected to the mounting assembly 10 and located on the periphery of the first rotating member 211. When the elastic limiting member 22 elastically abuts against the limiting groove 21113, the rotating clamping member 21 is limited on the mounting assembly 10. When the rotating clamping member 21 continues to rotate, the elastic limiting member 22 elastically contracts to exit the limiting groove 21113. When the rotating clamping member 21 tightens the clamped sewing thread 200, the elastic limiting member 22 elastically abuts against the corresponding limiting groove 21113, thereby limiting the rotating clamping member 21.

[0062] In the embodiments of this application, please refer to Figure 3-4 As shown, the number of limiting grooves 21113 is greater than or equal to the number of elastic limiting members 22. When the number of limiting grooves 21113 is greater than the number of elastic limiting members 22, it is easier for the surgeon to rotate the rotating clamp 21 to overcome the limiting resistance of the elastic limiting member 22. When the number of limiting grooves 21113 is equal to the number of elastic limiting members 22, the elastic limiting member 22 can more stably limit the rotating clamp 21.

[0063] In the embodiments of this application, the limiting abutment portion 21111 has twelve limiting grooves 21113, and each tensioning component 20 includes four elastic limiting members 22, which can be elastically held in one of the limiting grooves 21113.

[0064] In the embodiments of this application, the elastic limiting member 22 is a positioning bead screw. The positioning bead of the positioning bead screw can extend into the limiting groove 21113 to restrict the rotation of the rotating clamping member 21, thereby limiting the rotating clamping member 21 on the mounting assembly 10 and keeping it in a relatively stationary state with respect to the mounting assembly 10. The screw of the positioning bead can also be removed from the limiting groove 21113 to release the restriction on the rotating clamping member 21, thereby allowing the rotating clamping member 21 to rotate relative to the mounting assembly 10.

[0065] Please refer to Figure 3-6 As shown, the tensioning assembly 20 also includes a connecting plate 23, on which a plurality of positioning ball screws are threadedly connected, with the positioning balls of each positioning ball screw facing the limiting abutment portion 21111. The connecting plate 23 is mounted on the mounting assembly 10. By setting the connecting plate 23 for mounting the positioning ball screws, the positioning ball screws can be mounted on the mounting assembly 10 through the connecting plate 23 to achieve a limiting connection of the plurality of positioning ball screws, thereby reducing the difficulty of connecting the plurality of positioning ball screws to the mounting assembly 10; or, the positioning ball screws can be directly threaded onto the mounting assembly 10, with the positioning balls of each positioning ball screw facing the limiting abutment portion 21111, thereby simplifying the overall structure of the tensioning assembly 20.

[0066] Further, please refer to Figure 6-8 As shown, the first rotating member 211 includes a first segment 2111 and a second segment 2112. The end of the first segment 2111 facing away from the second segment 2112 is the first clamping surface 21115, and the end of the second segment 2112 facing away from the first segment 2111 is configured to form the limiting abutment portion 21111.

[0067] The mounting assembly 10 includes a first mounting plate 11, a second mounting plate 12, and a plurality of fasteners 13. The first mounting plate 11 and the second mounting plate 12 are connected by the plurality of fasteners 13 and are configured to form a plurality of mounting cavities 14.

[0068] In this configuration, at least one of the fixing members 13 passes sequentially through the first mounting plate 11, the connecting plate 23, and the second mounting plate 12. The elastic limiting member 22 is connected to the connecting plate 23. The first segment 2111 extends at least partially out of the second mounting plate 12, and the second segment 2112 is confined within the mounting cavity 14 and elastically abuts against the elastic limiting member 22.

[0069] Furthermore, the cross-sectional area of ​​the second segment 2112 is larger than that of the first segment 2111, and the second segment 2112 is entirely located within the mounting cavity 14, while the portion of the first segment 2111 near the second segment 2112 extends through the second mounting plate 12 and out of the mounting assembly 10.

[0070] By setting the mounting cavity 14, the second segment 2112, the connecting plate 23, and the elastic limiting member 22 are all installed in the mounting assembly 10. Under the limitation of the mounting cavity 14 and the elastic resistance limitation of the multiple elastic limiting members 22, the rotating clamping member 21 can be stably connected to the mounting assembly 10, thereby reducing the difficulty of connecting the tensioning assembly 20 to the mounting assembly 10 and reducing the installation difficulty of the elastic limiting member 22.

[0071] In the embodiments of this application, both ends of each suture 200 are clamped by the same rotating clamp 21, so that the rotating clamp 21 can simultaneously tension both ends of the suture 200 during rotation, so that the suture 200 can be adaptively pulled and tensioned; or, both ends of each suture 200 are clamped by any two rotating clamps 21 respectively. For a plurality of rotating clamps 21, both ends of each suture 200 can be clamped by two adjacent rotating clamps 21 respectively, and the two ends of the suture 200 can be tensioned by rotating the two rotating clamps 21 respectively; or both ends of each suture 200 can be clamped by any two non-adjacent rotating clamps 21 respectively, and the two ends of the suture 200 can be tensioned by rotating the two rotating clamps 21 respectively.

[0072] Please see Figure 2 As shown in the embodiments of this application, eight tensioning components 20 are connected to the mounting component 10. For a suturing surgery that requires four sutures 200, the eight tensioning components 20 can be divided into four groups, each group including two tensioning components 20. The two tensioning components 20 in each group clamp the two ends of the same suture 200 respectively.

[0073] In the embodiments of this application, please refer to Figure 1-2As shown, multiple tensioning components 20 are staggered and connected to the mounting assembly 10 so that any tensioning component 20 is not obstructed by other tensioning components 20 during the clamping and winding of the suture 200, allowing the surgeon to operate more efficiently. In addition, the spacing between the multiple sutures 200 can be effectively controlled so that the tensioned sutures 200 can be locked together using locking devices.

[0074] In the embodiments of this application, the elastic limiting member 22 may also be a metal spring or other elastic structure that can elastically resist within the limiting groove 21113, and no specific limitation is made here.

[0075] In the embodiments of this application, the rotating clamp 21 is an integral structure and is configured to form a thread clamping groove. The thread clamping groove is used to clamp at least one end of a thread 200, and as the rotating clamp 21 rotates, the thread 200 is gradually wound around the rotating clamp 21 until the wound thread 200 is taut.

[0076] In the embodiments of this application, please refer to Figure 7-9 As shown, the outer surfaces of the first rotating member 211 and the second rotating member 212 are respectively provided with anti-slip protrusions 214, so that the operator can operate the first rotating member 211 and the second rotating member 212 more smoothly.

[0077] In an embodiment of this application, the mounting assembly 10 further includes a base 30, which is connected to the side of the first mounting plate 11 opposite to the second mounting plate 12.

[0078] On the other hand, please see Figure 10 and combined Figure 1-9 As shown, this application also provides an interventional medical system 1000, which includes the above-mentioned suture tensioning device 100. Therefore, the interventional medical system 1000 has all the beneficial effects of the suture tensioning device 100, which will not be repeated here.

[0079] In an embodiment of this application, the interventional medical system 1000 further includes a mounting base 300, and the suture tensioning device 100 is disposed on the mounting base 300 so that the suture tensioning device 100 can more stably clamp and tension the suture 200.

[0080] Furthermore, the base 30 is detachably connected to the mounting base 300, so that the suture tensioning device 100 is detachably connected to the mounting base 300. The mounting base 300 is used to hold surgical instruments. By placing the suture tensioning device 100 on the mounting base 300, the suture tensioning device 100 is easy to assemble and disassemble and easy for the surgeon to operate. At the same time, the mounting base 300 can be used to adjust the position and angle of the suture tensioning device 100.

[0081] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0082] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0083] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
