[0027] In order to solve the problems existing in the prior art, the present application provides a vascular suture device with a deflection angle indicator. Specifically, Figure 1-Figure 10 As shown, the vascular suturing device includes a control handle 2, one end of which is slidably provided with a needle handle button 1, the other end of which is provided with a suturing catheter 3, and the end of the control handle 2 close to the suturing catheter 3 is also provided with a rotating shaft 25, a visual window 26 and a plurality of identification units 27 arranged at an angle, an indicator needle 28 is rotatably provided on the rotating shaft 25, and when the vascular suturing device is in use, the indicator needle 28 will deflect in the opposite direction when the suturing device deviates from a certain angle, and the indicator needle 28 structure is exposed through the visual window 26 and the identification unit 27, thereby reminding the operator that the designated position has been reached, realizing visualization of the operation process, and facilitating the operator to quickly and accurately locate the suturing position, thereby further shortening the operation time and improving the success rate of the operation and the hemostatic effect.

[0028] Preferably, a plurality of identification units 27 are provided, and each identification unit 27 is provided at a different angle, so as to meet the needs of different swing angles of the stapler during the suturing operation and improve the operation efficiency.

[0029] Preferably, in this embodiment, refer to Figure 5The indicator needle 28 is provided with an indicator end 281, a rotating ring 282 and a counterweight 283. The rotating ring 282 is sleeved on the rotating shaft 25. The weight of the indicator end 281 is lighter than the weight of the counterweight 283. When the suture device is used, when the suture device is swung at a certain angle, the indicator needle 28 will swing in the direction opposite to the swing direction of the suture device under the action of the gravity of the counterweight 283. When the indicator end 281 of the indicator needle 28 swings to the position of one of the identification units 27 required by the operator, the operator can start suturing.

[0030] For further information, please refer to Figure 1-Figure 7 The suture catheter 3 includes a guide post 31 and a guide sheath tube 32 , one end of the guide post 31 is connected to the control handle 2 , and the other end of the guide post 31 is connected to the guide sheath tube 32 .

[0031] Furthermore, a needle tube 311 and a steel needle 312 are arranged inside the guide column 31 , and one end of the needle tube 311 away from the control handle 2 is connected to a needle head 314 , and the needle head 314 is connected to one end of the suture 313 .

[0032] Furthermore, a push rod 12 is provided inside the needle tube 311 . When suturing a blood vessel, the push rod 12 is used to push the needle 314 to separate the needle 314 from the needle tube 311 .

[0033] For further information, please refer to Figure 2-Figure 7 The end of the guide sheath 32 connected to the guide post 31 is provided with a blood inlet 321, a thread foot 322, a suture shaft 323 and a guide wire exchange port 324 in sequence in the direction away from the connection end, and the non-connecting ends of the guide sheath 32 and the guide post 31 are provided with a hemostatic valve 325. The thread foot 322 and the suture shaft 323 cooperate to transport the connecting wire 315 to the blood vessel wall. The guide wire exchange port 324 is used to introduce the guide sheath 32 into the blood vessel under the guidance of the guide wire, and the hemostatic valve 325 is used to prevent blood from flowing out of the guide wire exchange port 324 during the operation.

[0034] Preferably, the suture shaft 322 is an annular structure (the opening is not closed). On the one hand, it is convenient for the suture to be detached from the opening position when the suture device is withdrawn from the blood vessel. On the other hand, it ensures that a track is formed during the suture pulling process, ensuring that the suture 313 does not become knotted or entangled during the transportation process, thereby ensuring the smooth transportation of the suture 313.

[0035] Further, such as Figure 7 As shown, the stitch 322 includes a first stitch and a second stitch, the first stitch is provided with a first sleeve 3221, the second stitch is provided with a second sleeve 3222, the first sleeve 3221 is connected to one end of the connecting line 315, and the second sleeve 3222 is connected to the other end of the connecting line 315. During the process of suturing the blood vessel, the steel needle 312 is connected to the first sleeve 3221, and the needle 314 provided at the end of the needle tube 311 is connected to the second sleeve 3222.

[0036] For further information, please refer to Figure 1-Figure 6 A needle handle shoulder 11 is provided at one end of the needle handle button 1 close to the control handle 2, and a handle 21, a dial button 22 and a quick scissor opening 23 are sequentially provided on the control handle 2 in a direction away from the needle handle shoulder 11. The quick scissor opening 23 is provided between the dial button 22 and the indicator needle 28, and a bleeding opening 24 is also provided on the side close to the quick scissor opening 23.

[0037] Preferably, the proximal end of the needle handle button 1 is a flat cap-type structure, which facilitates operations such as pushing and pulling the needle handle button 1 when the vascular suturing device is in use.

[0038] Preferably, the bleeding port 24 is connected to the blood inlet 321, and whether the front end guide sheath tube 32 has entered the blood vessel can be determined by observing whether there is uninterrupted pulsating blood spurting from the bleeding port 24.

[0039] Further, before starting to sew, that is, the suturing device is in the initial state (such as Figure 1 When the dial button 22 is pushed to put the suture device in the state of waiting for suturing (as shown in FIG. Figure 2 As shown in the figure, the stitch 322 is opened in the blood vessel. At this time, one end of the hand holds the handle 21, and the thumb of the other end pushes the needle handle button 1 to make the steel needle 312 and the needle head 314 pass through the blood vessel wall. The steel needle 312 is connected to the first sleeve 3221 on the first stitch, and the needle head 314 is connected to the second sleeve 3222 on the second stitch, so that the suture 313 and the connecting line 315 form a whole. Furthermore, the quick scissor mouth 23 is used to quickly and accurately cut the suture 313 after suturing, so that the needle handle button 1 and the suturing device are separated, so as to facilitate the ejection of the entire suturing device.

[0040] It is understandable that accurately determining the suture position by setting the indicator needle 28 is only one embodiment provided by the present solution, and the suture position can also be determined by setting a marking band along the axial direction on the outer periphery of the guide column 31. The axial direction refers to the direction from the distal end to the proximal end or from the proximal end to the distal end.

[0041] The process of using the vascular suture device of this embodiment is as follows: insert the guide sheath 32 into the blood vessel from the puncture point, observe the blood flow of the bleeding hole 24, and when the bleeding hole 24 has uninterrupted pulsating blood spurting, swing the angle of the suture device. At this time, the indicator needle 28 will swing in the opposite direction of the swing direction of the suture device under the gravity of the counterweight 283. When the indicator end 281 of the indicator needle 28 swings to one of the identification units 27 positions required by the operator, keep the suture device still, and turn the dial button 22 to Figure 2The position shown is opened, the thread pin 322 is opened, and the suture device is slowly withdrawn at this time, and the withdrawal resistance is felt and the bleeding port 24 is observed to see whether bleeding has stopped, so as to determine whether suturing can be started. Then the needle handle button 1 is pressed until the needle handle shoulder 11 on the needle handle button 1 is in close contact with the suture device body, so that the steel needle 312 and the needle head 314 pass through the blood vessel wall, the steel needle 312 is connected to the first sleeve 3221 on the first thread pin, and the needle head 314 is connected to the second sleeve 3222 on the second thread pin, and the push rod 12 pushes the needle head 314 out of the needle tube 311. Then slowly pull out the needle handle button 1, take out the steel needle 312, the first sleeve 3221, the second sleeve 3222, the connecting line 315, the needle 314 and one end of the suture 313 connected to the needle 314, tighten the suture 313, wrap it around the quick scissors to cut the suture 313, restore the dial button 22 to its initial position, retract the thread foot 322, withdraw the suture device, withdraw the guide sheath 32, and prepare to push the knot and tie the knot.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
