Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical machinery technology, specifically to a vascular hemostasis knotting and thread feeding device. Background Technology
[0002] Vascular ligation is a commonly used hemostasis method in surgery. In current technology, doctors generally use vascular clamps, suture feeders or forceps to hold the ligature, deliver the ligature around the target blood vessel and bring it out, and then tie a knot to finally tighten the target blood vessel.
[0003] However, situations often arise during surgery where multiple knots need to be tied around the target blood vessel. For example, in thoracic surgery, three knots are required to better control bleeding in the anterior trunk of the right pulmonary artery. Current suture delivery methods cannot pass multiple sutures around the target blood vessel at once; instead, doctors need to perform multiple operations, delivering multiple sutures and tying them one by one. These multiple operations interfere with the surgical field, increasing the risk of damage to blood vessels or surrounding tissues. They also prolong the operation time, increase patient suffering, and increase the workload of medical staff, resulting in a poor experience for both patients and doctors. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a vascular hemostasis knotting and suture delivery device, which solves the problem that existing technologies cannot deliver multiple ligatures around the target blood vessel at once.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] The present invention discloses a vascular hemostasis knotting and feeding device, which includes a feeding rod, one end of which is provided with a feeding structure for bypassing the blood vessel, and a fixing structure for fixing multiple ligatures on the feeding rod.
[0007] In a preferred embodiment, the wire feeding structure is a curved structure formed by one end of the wire feeding rod being raised; the wire fixing structure includes multiple grooves opened on one side of the wire feeding rod.
[0008] In a preferred embodiment, the wire fixing structure further includes fixing blocks, with multiple sets of fixing blocks provided on both sides of the top of each groove, and the fixing blocks cooperate with the groove and the wire to form an interference fit.
[0009] In one embodiment, a disconnector is also included, the disconnector comprising:
[0010] The connecting rod is located on one side of the wire feeding member.
[0011] The blade is fixedly connected to the top of the connecting rod.
[0012] In a preferred embodiment, the wire disconnector is connected to the wire feeding rod via a connecting mechanism, the connecting mechanism comprising:
[0013] Grooving: A groove is cut on one side of the wire feed rod.
[0014] The buckle is a sliding connection buckle with a slotted outer surface, and the top of the buckle is used to fix the connecting rod.
[0015] In another preferred embodiment, the wire cutter is fixedly connected to the wire feeding rod via a connecting rod.
[0016] In one embodiment, the wire feed rod is made of medical-grade solid silicone.
[0017] In a preferred embodiment, the end of the wire feeding structure is configured as a curved truncated cone structure, and the end of each groove near the wire feeding structure moves toward the center of the wire feeding rod.
[0018] In a preferred embodiment, the edge of the wire feeding structure of the wire feeding member is rounded inward.
[0019] In a more preferred embodiment, the ends of the wire feeding structure are provided with openings that are adapted to the orientation of each groove.
[0020] This invention provides a vascular hemostasis knotting and suture feeding device. Compared with the prior art, it has the following advantages:

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] This application provides a vascular hemostasis knotting and suture feeder, which solves the problem that multiple ligatures cannot be wrapped around the blood vessel and knotted at once during the vascular knotting process. It enables multiple ligatures to be wrapped around the target blood vessel at once, thereby improving the efficiency of vascular ligation.
[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0034] Example 1:
[0035] See Figures 1-2 As shown, this application discloses a vascular hemostasis knotting suture feeder, including a suture feeder rod. One end of the suture feeder rod is provided with a suture feeder structure 1 for bypassing the blood vessel, and the suture feeder rod is also provided with a suture fixing structure 2 for fixing multiple sutures. It should be noted that: when performing vascular knotting, the doctor sets the required number of sutures for knotting through the suture fixing structure. The suture setting step can be done by the assistant doctor before or during the operation; when knotting, the doctor uses the suture feeder structure to bypass multiple sutures around the target blood vessel at once, and then knots them, avoiding damage to the vascular tissue from multiple suture feeding and knotting operations, and improving the efficiency of knotting.
[0036] See Figures 1-2As shown, in a preferred embodiment, the suture delivery structure 1 is a curved structure formed by one end of the suture delivery rod being raised; the suture fixing structure 2 includes multiple grooves 21 opened on one side of the suture delivery rod. It should be noted that: the curved structure is a "J"-shaped structure, the grooves 11 are opened inside the curved structure and extend to the end of the suture delivery rod. The grooves 11 are C-shaped groove structures with their openings facing away from the suture delivery rod. The end of the groove 11 near the suture delivery structure and the end away from the suture delivery structure are open. The grooves 11 are slidably connected to the sutures. The doctor can insert the required number of sutures for knotting through the open end of the groove 11 away from the suture delivery structure. The C-shaped groove structure can prevent the sutures from accidentally falling off and deliver the sutures along the grooves 11 to one end of the suture delivery structure. Then, the sutures can be wrapped around the target blood vessel through the curved structure. The sutures wrapped around the target blood vessel and the sutures obtained from the open end of the grooves 11 near the suture delivery structure are knotted. The grooves 11 can independently hold the sutures, avoiding the inconvenience caused by multiple sutures tangling together, and making it easier for the doctor to manage the sutures.
[0037] See Figure 3 As shown, in a preferred embodiment, the suture fixing structure 2 further includes fixing blocks 22. Multiple sets of fixing blocks 22 are provided on both sides of the top of each groove 21. The fixing blocks 22 cooperate with the groove 21 to form an interference fit with the suture. It should be noted that the groove 11 can be a shallow groove structure, which can further reduce the thickness of the suture feeding rod, facilitating its entry into the patient's body, while retaining guidance for the suture. The outer edge of the fixing block 22 cooperates with the inner edge of the groove 11 to form an interference fit with the suture, thereby slidingly connecting the suture and preventing it from falling off.
[0038] Example 2:
[0039] See Figure 4 As shown, this application proposes a vascular hemostasis knotting and suture feeder, including the device involved in the above-described embodiment 1 and preferred embodiment, and further including a suture cutter 3. The suture cutter 3 includes: a connecting rod 31, which is disposed on one side of the suture feeder, and a blade 32, which is fixedly connected to the top of the connecting rod 31. It should be noted that the blade 32 consists of two thin plates fixedly connected to each other by a torsion spring. The opposite sides of the two thin plates are sharpened, and one of the thin plates is fixedly connected to the connecting rod 31. When the doctor feeds the suture through the suture feeder, the suture cutter does not bypass the target blood vessel. After the doctor completes the knotting, the excess sutures are placed between the blades 32, and the blades 32 are pressed with a device such as vascular clamps or tweezers to cut the sutures in one go, further improving the knotting efficiency.
[0040] See Figure 4As shown, in a preferred embodiment, the suture cutter 3 is connected to the suture feeder via a connecting mechanism 4. The connecting mechanism 4 includes: a slot 41, which is formed on one side of the suture feeder; a buckle 42, which is slidably connected to the outer surface of the slot 41; and a connecting rod 31 is fixedly connected to the top of the buckle 42. It should be noted that the position of the suture cutter can be adjusted by sliding the buckle 32 through the slot 31, and the position of the suture cutter can be fixed by pressing the buckle 32 on one side of the suture feeder, thereby further adapting to vascular knotting operations in different surgical fields and locations.
[0041] See Figure 5 As shown, in another preferred embodiment, the wire cutter 3 is fixedly connected to the wire feeding member via a connecting rod 31. It should be noted that the blade 32 is directly fixedly connected to the wire feeding member via the connecting rod 31, resulting in a simpler structure that is easier to manufacture and use.
[0042] Example 3:
[0043] This application discloses a vascular hemostasis knotting and feeding device, including the apparatus described in any one of embodiments 1-2 and any preferred embodiment above. Furthermore, the feeding rod is made of medical-grade solid silicone. It should be noted that the medical-grade solid silicone material reduces damage to blood vessels and tissues caused by accidental impacts when the feeding structure is used to knot the vascular bundle around blood vessels or tissues.
[0044] In a preferred embodiment, the end of the wire delivery structure 1 is configured as a curved truncated cone structure, and the end of each groove 21 near the wire delivery structure 1 moves closer to the center of the wire delivery rod. It should be noted that the flat-headed cone structure and the mutually converging grooves can reduce the width of the wire delivery structure, making it easier to pass through the gap between the target blood vessel and the tissue.
[0045] In a preferred embodiment, the edge of the wire delivery structure 1 is rounded inward. It should be noted that the rounded chamfer at the edge of the wire delivery structure reduces the risk of damage to blood vessels and tissues from accidental impacts during wire delivery.
[0046] In a more preferred embodiment, the end of the suture delivery structure 1 is provided with an opening structure that is adapted to the orientation of each groove 21. It should be noted that when the doctor delivers the suture to the end of the groove 11 near the suture delivery structure and it passes through the opening, the bottom of the opening structure can push the suture forward when the suture delivery rod passes through the gap between the blood vessel and the tissue. After passing around the target blood vessel, the suture in the opening can be easily retrieved by the doctor for knotting, which improves the doctor's work efficiency.
[0047] In summary, compared with existing technologies, it has the following beneficial effects:
[0048] 1. Through the suture delivery structure and suture fixing structure, namely the curved structure formed by the upturned end of the suture delivery rod and the multiple grooves opened on one side of the rod, doctors can pass multiple sutures around the target blood vessel at once when performing suture knotting operations, and then perform the knotting operation, without having to knot them one by one in multiple operations, which improves the efficiency of blood vessel ligation, shortens the operation time, and improves patient satisfaction.
[0049] 2. The connection mechanism of the suture cutter and the adjustment of the suture cutter position improves the efficiency of doctors in knotting and cutting sutures, and further improves the adaptability of this application to vascular knotting operations in different surgical fields and sites.
[0050] 3. By setting the wire delivery structure as a curved flat-headed cone structure, the groove structure that comes together near the end of the wire delivery structure, the rounded chamfer of the edge of the wire delivery structure, and the opening structure at the end of the groove near the end of the wire delivery structure, the wire delivery device of this application can easily pass through the gap between the target blood vessel and the tissue, reduce the damage to blood vessels and tissues caused by accidental bumps during wire delivery, and improve the doctor's work efficiency.
