Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary device for suturing blood vessels in interventional cardiology surgery and a method of using the device. Background Art

[0002] Vascular suture needles and hooks are important tools in the medical field. They are mainly used to suture blood vessels during surgery and are one of the indispensable equipment in surgical operations. With the assistance of auxiliary devices for vascular suture in interventional cardiology surgery, the operation time for vascular suture can be reduced and the accuracy and effect of suture can be improved.

[0003] Existing vascular suture needles have an elongated body and a sharp tip to penetrate tissue and remain stable when suturing within a blood vessel, while a thread hook has one or more small hooks for catching and manipulating threads or sutures that need to be handled during surgery.

[0004] The suture thread and needle body of the blood vessel suture needle are connected together. During the suturing process, the doctor needs to pass the suture needle through the suture opening of the blood vessel, and then carry the suture thread through the gap in the blood vessel. Then the doctor needs to use a scissors tool to cut the suture thread and the suture needle, and then suture the blood vessel with the help of a thread hook. During the process, the scissors tool will enter the inside of the patient's skin to cut the suture thread, which will cause the scissors tool to easily cause secondary damage to the tissue at the blood vessel. For this reason, the present invention proposes an auxiliary device for vascular suturing in interventional cardiology surgery and a method of using the same. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an auxiliary device for vascular suturing in interventional cardiology surgery and a method of using the device, which solves the problem that after the traditional vascular suture needle punctures the blood vessel, it is necessary to use scissors to enter the wound to cut the suture thread, which easily causes secondary damage to the wound.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an auxiliary device for vascular suturing in interventional cardiology surgery and a method of using the same, comprising:

[0007] A needle body, wherein the top end of the needle body is provided with a puncture section for puncturing a blood vessel, and the bottom end of the needle body is provided with a clamping portion for cooperating with forceps for fixing;

[0008] A fixing section, which is used to fix the suture thread used for suturing blood vessels, is installed at the bottom of the clamping part, and the fixing section is provided with two symmetrically distributed anti-slip points on the outside;

[0009] A buckle sleeve, which is sleeved on the outside of the fixing joint and is used to tighten the fixing joint, and has slots on both sides of the buckle sleeve;

[0010] The holding part has a movable groove at the top thereof to provide space for the wire hook to rotate, and a closed groove at the bottom wall thereof to provide storage space for the connecting wire, and the connecting wire is used to connect the wire hook and an adjusting rod movable inside the holding part.

[0011] Preferably, the puncture segment is made of polylactic acid.

[0012] Preferably, an inner side of the fixing section is provided with an oblique angle for assisting the installation of the suture.

[0013] Preferably, the anti-slip point is engaged with the card slot, and the anti-slip point is located inside the buckle sleeve.

[0014] Preferably, an anti-skid portion is provided on the outer side of the holding portion for preventing skidding.

[0015] Preferably, the bottom end of the adjusting rod passes through the holding portion and is fixedly connected to a handle.

[0016] Preferably, a top plate for limiting the rotation of the wire hook is fixedly connected to the top of the holding portion.

[0017] Preferably, the top end of the adjusting rod passes through the closed slot and abuts against the bottom of the wire hook.

[0018] A method for using an auxiliary device for vascular suturing in interventional cardiology surgery comprises the following steps:

[0019] S1. When in use, the puncture segment made of polylactic acid has a certain plasticity. The doctor can fine-tune the angle of the puncture segment according to the suturing scene, clamp the fixed clamping part with tweezers, and then operate the needle body and the puncture segment to puncture the blood vessel. After the puncture is completed, the suture thread will pass through the tissue at the wound of the blood vessel, thereby tightening and closing the wound of the blood vessel;

[0020] S2, the doctor then uses the tweezers to clamp and fix the clamping part, inserts another tweezer into the slot on the buckle sleeve, and then presses the tweezers hard to squeeze the anti-slip point out of the slot through the tweezers. With the cooperation of the bevel, the fixing section is deformed to pull the anti-slip point out of the slot. When the fixing section is separated from the buckle sleeve, it will expand, thereby loosening the clamped suture, and then the buckle sleeve is removed from the suture, thereby completing the separation of the suture and the suture needle quickly and conveniently.

[0021] S3. At the same time, when tightening the two ends of the suture and suturing the wound of the blood vessel, the suture is hooked on the inside of the hook. Then the doctor pushes the handle and the adjusting rod with his fingers to move. When the adjusting rod moves, it pulls the bottom of the hook through the connecting line to make it rotate inside the movable groove until the top of the hook turns over and contacts the outside of the holding part. At this time, the inside of the hook is in a closed state, which can effectively restrict the suture hooked on the inside of the hook to prevent it from falling off. When loosening, just push the adjusting rod in the opposite direction to push the bottom of the hook through the adjusting rod, so that the hook rotates away from the outside of the holding part, thereby releasing the restriction on the suture.

[0022] The present invention provides an auxiliary device for vascular suturing in interventional cardiology surgery and a method of using the device. The device has the following beneficial effects:

[0023] 1. The present invention clamps and fixes the clamping part, and another tweezer tool is inserted into the slot on the buckle sleeve. Then the tweezer tool is pressed hard, and the anti-detachment point is squeezed out of the slot by the tweezer tool. With the cooperation of the bevel angle, the fixed section is deformed to pull the anti-detachment point out of the slot, thereby quickly completing the disassembly of the fixed section, so that the suture can be separated from the suture needle conveniently and quickly without the assistance of other tools, effectively improving the efficiency and safety of the device in suturing blood vessels.

[0024] 2. The present invention pushes the handle and the adjusting rod to move. When the adjusting rod moves, the bottom of the wire hook will be pulled through the connecting line to make it rotate inside the movable groove until the top of the wire hook turns over and contacts the outside of the holding part. At this time, the inside of the wire hook is in a closed state, which can effectively limit the suture thread hooked on the inside of the wire hook to prevent it from falling off, making the doctor more stable when hooking the thread, thereby ensuring that the operation of blood vessel suturing is simpler and improving the efficiency of suturing.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example:

[0035] Please refer to the attached Figure 1 -Attached Figure 7 The embodiment of the present invention provides an auxiliary device for vascular suturing in interventional cardiology surgery, comprising:

[0036] The needle body 1 includes a puncture section 2 at the top and a clamping portion 3 at the bottom. The puncture section 2 is made of polylactic acid material, which has high biocompatibility and moderate hardness. It can effectively penetrate the blood vessel wall without causing excessive damage. It also has a certain plasticity. When using the puncture needle to suturing and puncturing blood vessels, the physician can adjust the deformation angle of the puncture section 2 according to the position of the blood vessels in different parts, so as to adapt to the puncture and suturing of blood vessels in different parts. The puncture section 2 can quickly and accurately puncture the blood vessel through the sharp structure of its tip and pass the suture thread 8 to the wound of the blood vessel;

[0037] The fixing section 4 is installed on the clamping part 3 at the bottom of the needle body 1, and is used to fix the suture 8, so that the suture needle can carry the suture 8 through the blood vessel during operation. The inner side is provided with an angled angle 9 for assisting the installation of the suture 8, so that the suture 8 can be more stably fixed on the fixing section 4, and the suture 8 clamped and fixed inside can be released when the fixing section 4 is taken out. The outside of the fixing section 4 is provided with two symmetrically distributed anti-drop points 5, which are engaged with the card slot 7 on the buckle sleeve 6 to prevent the fixing section 4 from accidentally falling off during operation, thereby ensuring the safety and stability of the suturing process;

[0038] The buckle sleeve 6 is sleeved on the outside of the fixing section 4, and is engaged with the anti-detachment point 5 on the fixing section 4 through the slots 7 on both sides thereof. The buckle sleeve 6 is designed to loosen or tighten the fixing section 4 when needed, so that the doctor can adjust the connection and separation of the suture thread 8 according to actual needs, thereby ensuring the accuracy and reliability of blood vessel suture;

[0039] A movable groove 12 is provided at the top of the holding portion 10 to provide space for the rotation of the wire hook 13. A closed groove 14 is provided at the bottom wall of the movable groove 12 to accommodate a connecting wire 16. The connecting wire 16 connects the wire hook 13 and an adjusting rod 15 movable inside the holding portion 10. The adjusting rod 15 passes through the closed groove 14 through the top and abuts against the bottom of the wire hook 13. The position of the adjusting rod 15 is adjusted by a handle 17 to control the rotation of the wire hook 13, so that the doctor can better control the wire hook 13 to operate the suture thread 8 during the suturing process.

[0040] A method for using an auxiliary device for vascular suturing in interventional cardiology surgery comprises the following steps:

[0041] S1. When in use, the puncture section 2 made of polylactic acid has a certain plasticity. The doctor can fine-tune the angle of the puncture section 2 according to the suturing scene, clamp the clamping part 3 with tweezers, and then operate the needle body 1 and the puncture section 2 to puncture the blood vessel. After the puncture is completed, the suture thread 8 will penetrate the tissue at the wound of the blood vessel, thereby tightening and closing the wound of the blood vessel;

[0042] S2, the doctor then uses the tweezers to clamp and fix the clamping part 3, and inserts another tweezer into the slot 7 on the buckle sleeve 6, and then presses the tweezers with force to squeeze the anti-slip point 5 out of the slot 7 through the tweezers. With the cooperation of the bevel 9, the fixing section 4 is deformed to pull the anti-slip point 5 out of the slot 7. When the fixing section 4 is separated from the buckle sleeve 6, it will unfold, thereby loosening the clamped suture 8, and then the buckle sleeve 6 is removed from the suture 8, thereby completing the separation of the suture and the suture needle quickly and conveniently.

[0043] S3. At the same time, when tightening the two ends of the suture and suturing the wound of the blood vessel, the suture is hooked on the inner side of the wire hook 13, and then the doctor pushes the handle 17 and the adjusting rod 15 with his fingers to move. When the adjusting rod 15 moves, it will pull the bottom of the wire hook 13 through the connecting line 16 to make it rotate inside the movable groove 12 until the top of the wire hook 13 turns over and contacts the outer side of the holding part 10. At this time, the inner side of the wire hook 13 is in a closed state, which can effectively restrict the suture hooked on the inner side of the wire hook 13 to prevent it from falling off. When loosening, just push the adjusting rod 15 in the opposite direction, and push the bottom of the wire hook 13 through the adjusting rod 15, so that the wire hook 13 rotates away from the outer side of the holding part 10, thereby releasing the restriction on the suture.
