Problems solved by technology

[0004] At present, the method of suturing the annulus fibrosus after nucleus pulposus surgery has relatively large defects, mainly because the current method is difficult to achieve full-thickness suture of the annulus fibrosus, thus weakening the effect of annulus fibrosus suturing, and cannot effectively prevent the recurrence of intervertebral disc herniation

Embodiment 1

[0031] Embodiment 1: A kind of jet guider, its structure reference figure 1 and figure 2 shown, including:

[0032] Wire bin 3 with hollow structure,

[0033] The upper end of the wire bin 3 has a syringe interface 1, the lower end of the wire bin 3 is airtightly connected with the puncture needle 5, the inside of the wire bin 3 is fixedly connected with a bobbin 2, and the bobbin 2 is wound with a suture thread 4, the suture thread One end of 4 is located inside the puncture needle 5, and the other end of the suture 5 is fixed on the bobbin 2 by bonding or socketing, so as to prevent the suture 5 from being completely ejected out of the jet introducer under the action of the physiological saline jet.

[0034] The bobbin 2 is a hollow structure with upper and lower openings, and the interface between the wire bin 3 and the puncture needle 5 has a circular cross-section, and a straight line perpendicular to the center of the circular cross-section coincides with the central ...

Embodiment 2

[0041] Embodiment 2: jet lead, its structure reference image 3 and Figure 4 shown, including:

[0042] Wire bin 3 with hollow structure,

[0043] The upper end of the wire bin 3 has a syringe interface 1, the lower end of the wire bin 3 is airtightly connected with the puncture needle 5, the inside of the wire bin 3 is fixedly connected with a bobbin 2, and the bobbin 2 is wound with a suture thread 4, the suture thread One end of 4 is located inside the puncture needle 5, and the other end of the suture 5 is fixed on the bobbin 2 by bonding or socketing, so as to prevent the suture 5 from being completely ejected out of the jet introducer under the action of the physiological saline jet.

[0044] The bobbin 2 is a hollow structure with upper and lower openings, and the interface between the wire bin 3 and the puncture needle 5 has a circular cross-section, and a straight line perpendicular to the center of the circular cross-section coincides with the central axis of the ...

Abstract

The invention relates to a flow-jetting suture guiding device. The flow-jetting suture guiding device comprises a suture bin of a hollow structure. An injector connector is arranged at one end of the suture bin. The other end of the suture bin is connected with a puncture needle in a sealed mode. A suture winding tube is fixedly connected to the interior of the suture bin, a suture is wound around the suture winding tube, one end of the suture is located inside the puncture needle, and the other end of the suture is fixed to the suture winding tube. The suture located in the suture bin is driven by jet flow formed by liquid media to move along an inner cavity of the puncture needle. The flow-jetting suture guiding device can be used for suturing a fiber ring after removal of the nucleus pulposus; after an operation is finished, protrusion of the intervertebral disc is not prone to relapsing; the flow-jetting suture guiding device can also be used for suturing and ligaturing other deep tissues.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a jet guider used for suturing the annulus fibrosus or suturing and ligating other deep tissues after nucleus pulposus extraction. Background technique [0002] The recurrence of intervertebral disc herniation is an important factor affecting the long-term effect of discectomy and open surgery for lumbar disc herniation. According to literature reports, more than 10% of patients with lumbar intervertebral disc herniation will relapse after excision of the nucleus pulposus, and more than half of them need reoperation. Annulus fibrosus repair has a potential effect on preventing the recurrence of intervertebral disc herniation. In vitro experiments have confirmed that annulus fibrosus repair after nucleus pulposus excision can help preserve intradiscal tissue and resist stress. [0003] Clinical studies have shown that the repair of the annulus fibrosus is valuable for preventing ...
