In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The first aspect of this application provides a surgical suture delivery device. (Refer to...) Figure 1 and Figure 2 , Figure 1 This is a partial structural schematic diagram of the surgical suture delivery device according to an embodiment of this application; Figure 2 This is a schematic diagram of the internal structure of the housing 100 of the surgical suture delivery device according to an embodiment of this application. The surgical suture delivery device includes a housing 100 and a suture delivery mechanism. The housing 100 is filled with inert gas, and a suture outlet hole (not shown in the figure) is provided on the first side wall of the housing 100. The housing 100 is used to hold the suture bundle; the suture delivery mechanism is used to drive the surgical suture in the suture bundle to be output from the suture outlet hole.

[0032] The surgical suture delivery device of this application embodiment can be applied in surgical suture production equipment. The suture bundle is placed inside the housing 100, which is filled with inert gas to reduce the risk of oxidation of the surgical suture in the suture bundle. The first side wall of the housing 100 is provided with a suture outlet hole through which the surgical suture passes. The suture bundle is connected to a suture delivery mechanism, which drives the surgical suture in the suture bundle to exit through the suture outlet hole, thereby delivering the surgical suture to the processing device in the surgical suture production equipment for processing the surgical suture. Therefore, the surgical suture delivery device of this application embodiment can deliver surgical sutures and reduce the risk of oxidation of the surgical sutures.

[0033] It should be noted that the surgical suture delivery device in this application embodiment is applied to a surgical suture production equipment. The surgical suture production equipment is used to process surgical sutures to obtain surgical sutures. The surgical suture production equipment may include a processing device for forming barbs on the surgical sutures; the processing device may also be a device for forming spiral barbs on the surgical sutures, or a device for forming fishbone-like barbs on the surgical sutures. This application embodiment does not specifically limit the structure of the surgical suture production equipment.

[0034] It is worth noting that the housing 100 is a closed structure and has an internal cavity filled with inert gas, and the wire bundle is placed inside the cavity of the housing 100. Figure 1The illustrated housing 100 is a cuboid shape, which is only an example and should not be construed as a limitation of this application. The housing 100 can also be other shapes, such as a cylinder.

[0035] It should be noted that the difference between the diameter of the suture outlet hole and the diameter of the surgical suture is less than a preset difference, so that the surgical suture can pass through the suture outlet hole and inert gas can be prevented from escaping from the suture outlet hole to the outside of the shell as much as possible.

[0036] In some embodiments, the first sidewall of the housing 100 is provided with a mounting port (not shown in the figure), and the surgical suture delivery device includes a mounting plate (not shown in the figure). The mounting plate is detachably mounted in the mounting port, and a suture outlet hole is provided on the mounting plate. Thus, different mounting plates can be used for surgical sutures of different apertures, and the aperture of the suture outlet hole on each mounting plate is different. Personnel can select the appropriate mounting plate to install into the mounting port according to actual needs. The mounting plate and the mounting port can be connected by a snap-fit ​​connection.

[0037] In some embodiments, the inert gas may be one or more of nitrogen, argon, helium, neon, krypton, and xenon. This application does not specifically limit the inert gas.

[0038] In some embodiments, the wire feeding mechanism is located inside the housing 100; while in other embodiments, the wire feeding mechanism is located outside the housing 100.

[0039] In some embodiments, an air intake structure (not shown in the figure) is also provided on one side wall of the housing 100 to inject inert gas into the housing 100. This application does not specifically limit the air intake structure, and those skilled in the art can set the air intake structure according to actual needs, for example, the air intake structure is a valve body.

[0040] In some embodiments, refer to Figure 2 It also includes a cover plate 200. The second side wall of the housing 100 is provided with an opening 111, and the cover plate 200 is movably connected to the second side wall. The cover plate 200 can move relative to the second side wall to open or close the opening 111.

[0041] Specifically, the cover plate 200 is movable from the second sidewall so that the cover plate 200 can open the opening 111 to place the wire bundle inside the housing 100, and the cover plate 200 can close the opening 111 to seal the housing 100 and prevent inert gas from leaving the housing 100.

[0042] In some embodiments, the cover plate 200 is detachably connected to the second sidewall, for example, by means of detachable screws. In other examples, the cover plate 200 is not detachably connected to the second sidewall, for example, one side of the cover plate 200 is hinged to the second sidewall so that the cover plate 200 can rotate relative to the second sidewall, thereby opening or closing the opening 111.

[0043] In some embodiments, the side of the cover plate 200 opposite to the housing 100 is provided with a recess or a protrusion, which facilitates user control of the rotation of the cover plate 200 relative to the second sidewall. The protrusion may be a handle.

[0044] In some embodiments, the first sidewall and the second sidewall are different sidewalls in the housing 100; while in other embodiments, the first sidewall and the second sidewall are the same sidewall in the housing 100.

[0045] In some embodiments, the second sidewall is provided with a groove 110 that matches the cover plate 200, the cover plate 200 is movably connected to the groove 110, and the opening 111 is provided on the bottom wall of the groove 110.

[0046] Specifically, the cross-sectional area of ​​the groove 110 matches the cross-sectional area of ​​the cover plate 200, so that the cover plate 200 can fit into the groove 110 and seal the opening 111, thereby sealing the housing 100. In one embodiment, one side of the cover plate 200 is hinged to one side wall of the groove 110, so that the cover plate 200 can rotate relative to the side wall of the groove 110, thereby opening or closing the opening 111.

[0047] In some embodiments, the cover 200 is a transparent article. Exemplarily, the transparent article is glass or a transparent acrylic sheet. Because the cover 200 is a transparent article, the user can observe the interior of the housing 100 through the cover 200, thereby observing the condition of the wire bundle.

[0048] In some embodiments, refer to Figure 2 The suture feeding mechanism includes a suture feeding shaft 320 and a servo tensioner 310. Both the suture feeding shaft 320 and the servo tensioner 310 are installed on the inner side wall of the housing 100. The suture feeding shaft 320 is used to hold the suture bundle, and the servo tensioner 310 is used to drive the surgical suture in the suture bundle to be output from the suture outlet hole.

[0049] It is worth noting that the servo tensioner 310 is an instrument used to precisely control the tension of materials during winding, unwinding, or transport. Its core function is to ensure that the material (e.g., surgical suture) maintains a constant tension by dynamically adjusting the torque of the drive or braking system to drive the material (surgical suture) to move. This application does not specifically limit the servo tensioner 310; those skilled in the art can select the appropriate servo tensioner 310 based on actual conditions. Specifically, the suture bundle is sleeved in the unwinding shaft 320, and the surgical suture in the suture bundle is connected to the servo tensioner 310. After passing through the servo tensioner 310, the surgical suture passes through the suture exit hole. Tension is applied to the surgical suture by the servo tensioner 310 to drive the surgical suture in the suture bundle to exit from the suture exit hole.

[0050] In some embodiments, the feeding mechanism further includes at least one limiting plate 321, which is mounted on the feeding shaft 320.

[0051] In one embodiment, one end of the wire feeding shaft 320 is installed on the inner side wall of the housing 100, and the other end is suspended. There is one limiting plate 321, which is installed on the suspended end of the wire feeding shaft 320. The wire bundle is located between the limiting plate 321 and the inner side wall of the housing 100. The limiting plate 321 is used to limit the wire bundle and prevent the wire bundle from falling off the wire feeding shaft 320.

[0052] In other embodiments, the number of limiting plates 321 is 2, and the two limiting plates 321 are spaced apart on the wire feeding shaft 320, with the wire bundle located between the two limiting plates 321.

[0053] It should be noted that the limiting plate 321 and the pay-off shaft 320 are detachably connected, and the limiting plate 321 and the pay-off shaft 320 are relatively fixed. For example, the limiting plate 321 and the pay-off shaft 320 are connected by threads.

[0054] In some embodiments, refer to Figure 3 and Figure 4 ; Figure 3 This is a schematic diagram of the suture cutting mechanism according to an embodiment of this application; Figure 4 This is a schematic diagram of the suture cutting mechanism from another angle according to an embodiment of this application. The surgical suture delivery device according to an embodiment of this application also includes a suture cutting mechanism, which includes a cutting component disposed on one side of the suture outlet hole. The surgical suture output from the suture outlet hole passes through the cutting component, which is used to cut the surgical suture.

[0055] Specifically, the cutting component is located on one side of the suture outlet hole, and between the suture outlet hole and the processing device of the surgical suture production equipment. The surgical suture exits from the suture outlet hole, passes through the cutting component, and is then fed into the processing device. The cutting component is used to cut the surgical suture, severing the connection between the surgical suture and the suture feeding mechanism located in the processing device, thus preventing the feeding mechanism from affecting the processing of the processing device.

[0056] In some embodiments, the cutting assembly includes a cutting drive 410, a baffle 430, and a cutter 421. The cutting drive 410 is disposed on one side of the suture outlet hole and is connected to the cutter 421. The baffle 430 is disposed opposite to the cutter 421. The surgical suture passes between the cutter 421 and the baffle 430. The cutting drive 410 is used to drive the cutter 421 to move closer to or away from the baffle 430 to cut the surgical suture.

[0057] In one embodiment, the cutting drive 410 is a drive cylinder, the cutter 421 is mounted on the mounting member 420, and the mounting member 420 is mounted in the cutting drive 410. The baffle 430 has a through-hole 431 corresponding to the cutter 421. When the cutting drive 410 drives the cutter 421 close to the baffle 430, the cutter 421 passes through the through-hole 431. The thread cutting mechanism also includes a push block 422, which is mounted on the mounting member 420 by an elastic member. The push block 422 is located on one side of the cutter 421, and the distance between the push block 422 and the baffle 430 is less than the distance between the cutter 421 and the baffle 430. During cutting, the cutting drive unit 410 drives the mounting unit 420 to move the cutter 421 and the pusher block 422 towards the baffle 430. During the movement, the pusher block 422 first contacts the surgical suture, and the pusher block 422 and the baffle 430 clamp the surgical suture. Then, the cutter 421 contacts the surgical suture and cuts it. Before the cutter 421 contacts the surgical suture, the pusher block 422 and the baffle 430 clamp the surgical suture to prevent the surgical suture from shaking and to facilitate cutting.

[0058] In some embodiments, the suture cutting mechanism further includes a clamping assembly, which includes a clamping drive 440 and two clamping pieces 441, which are located on opposite sides of the surgical suture. The clamping drive 440 is used to drive the two clamping pieces 441 to clamp or release the surgical suture.

[0059] Specifically, before the cutter 421 makes a cut, the two clamping plates 441 are driven by the clamping drive 440 to clamp the surgical suture, and then the cutter 421 makes a cut. In this way, the surgical suture can be clamped tightly to avoid the surgical suture from shaking and to facilitate cutting. Therefore, after the surgical suture is cut, the risk of the surgical suture getting tangled with other structures of the surgical suture production equipment can be reduced.

[0060] In some embodiments, the clamping drive 440 is a drive cylinder, and both clamping plates 441 are movable clamping plates 441. The two clamping plates 441 are installed in the clamping drive 440. The clamping drive 440 is used to drive the two clamping plates 441 to move closer to each other or further away from each other. When the two clamping plates 441 move closer to each other, they abut against each other, thereby clamping the surgical suture. When the two clamping plates 441 move further away from each other, the surgical suture is released.

[0061] In other embodiments, one of the two clips 441 is a movable clip 441 and the other is a fixed clip 441. The clip 441, which is a fixed clip 441, is fixed relative to the clamping drive member 440. The clip 441, which is a movable clip 441, is installed on the clamping drive member 440. The clamping drive member 440 is used to drive the clip 441, which is a movable clip 441, to move closer to or away from the clip 441, which is a fixed clip 441, so that the two come into contact, thereby clamping the surgical suture.

[0062] A second aspect of this application provides a surgical suture production apparatus, comprising:

[0063] Surgical suture delivery device as described in any of the embodiments of the first aspect of this application.

[0064] It is worth noting that surgical suture production equipment refers to equipment that processes surgical sutures, such as creating barbs or fishbone-like structures on them.

[0065] It is worth noting that since the surgical suture production equipment includes the surgical suture delivery device of the first aspect embodiment, the corresponding contents of the surgical suture delivery device of the first aspect embodiment can be applied to the surgical suture production equipment of the second aspect, and have the same implementation principle and technical effect. To avoid redundancy, it will not be described in detail here.

[0066] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0067] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
