Abstract

The invention provides a tunnel type thread passing device, a tunnel type thread passing system and an operation method of the tunnel type thread passing device. The tunnel type thread passing device comprises a transverse positioning rod and a longitudinal positioning rod. One part of the transverse positioning rod is used for penetrating into a transverse tunnel of a predetermined object; the transverse positioning rod is provided with a wire outlet and a transverse channel arranged in the axial direction of the transverse positioning rod. The part, located outside the transverse tunnel, of the transverse channel is used for being communicated with the positive pressure end or the outside. The thread outlet is formed in the part, penetrating into the transverse tunnel, of the transverse positioning rod, is communicated with the transverse channel and is used for allowing a thread or an implant to penetrate out of the transverse channel; the longitudinal positioning rod is provided with a longitudinal channel penetrating in the axial direction of the longitudinal positioning rod, and a part of the longitudinal positioning rod is used for penetrating into a longitudinal tunnel, intersecting with the transverse tunnel, of a preset object. The part, located outside the longitudinal tunnel, of the longitudinal channel is used for being connected with the negative pressure end, so that the far end of the longitudinal positioning rod sucks a thread or an implant penetrating out of the thread outlet through the longitudinal tunnel.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tunnel-type wire-passing device, a tunnel-type wire-passing system and an operating method thereof. Background technique [0002] For the repair of soft tissue tears in the rotator cuff, knee, ankle and other parts, in addition to suturing the soft tissue itself, it is generally necessary to press the soft tissue to the bone (binding the soft tissue to the bone) through sutures to promote its healing. At present, anchors with wires are usually used for repair surgery. The metal anchors are anchored in the bone, and then the sutures connected to the anchor are used to bind the soft tissue, thereby pressing the soft tissue to the bone. However, because the volume of the anchor is relatively thick compared with the suture, it is not friendly to patients with small bone size or osteoporosis. If the anchor is improperly selected or the fixation position is deviated during t...
