In recent years, surgical techniques have been greatly developed, and in the case of interventional operations or minimally invasive operations, suture (slipknots) are required to be knotted and fixed in the operation, and conventional surgical operations are performed under open and direct vision conditions, and are usually manually knotted by doctors. With the progress of technology, various minimally invasive operations and interventional operations, such as endoscopic operations, transcatheter interventional operations, and patent foramen ovale not necessarily occlusion operations, are increasingly popular, and such operations only require cutting a small operating window in the patient body, and instruments such as an endoscope or an interventional catheter are inserted into the patient body through the operating window to reach a predetermined position for treatment. In particular, the split-type or mortise-free occluder is used for the operation of occluding the defect part, the occluder in the patient needs to be fastened and fixed, and an auxiliary fastening wire (slipknot) needs to be knotted and fixed, so that a doctor usually needs to operate the occluder in the patient through a smaller operation window, and meanwhile, the occluder, or the fastening wire or the suture line needs to be withdrawn under the condition of failure of the operation, but no related device is needed at present to solve the problems.

When in use, as shown in fig. 4, firstly, the pre-buried knotting and conveying tangential device for interventional operation is placed in an off state (i.e. the tangential line communicating section 1202 is staggered with the limit communicating section 2202), the ready-made slipknot is placed in the limit pipe 20, the movable end of the slipknot passes through the movable end limit hole 210 and the movable end tangential line hole 110, then the limit pipe 20 is rotated to the right side through the driving component 40, i.e. the communicating state is reached (as shown in fig. 3), at this moment, the tangential line communicating section 1202 is aligned and communicated with the limit communicating section 2202, the fixed end of the slipknot is pulled downwards to the limit hole section 2201, then the limit pipe 20 is rotated leftwards, and the fixed end of the slipknot can be blocked in the limit hole section 2201 at this moment.
It should be noted that, as shown in fig. 2, when in use, an operator (or doctor) pulls the movable end of the slipknot with one hand, and pushes the device upwards with the other hand holding the holding member 30, so that the upper stopper surface 610 and the lower stopper surface 620 can be tightened, and after the upper stopper surface 610 and the lower stopper surface 620 are tightened, the limiting tube 20 can be driven by the driving component 40 to move along the axial direction of the holding member 30 so as to cut off the movable end of the slipknot (at this time, the fixed end of the slipknot is in a communicating state and is not blocked); when the tightening fails, an operator (or doctor) pulls the movable end of the slipknot with one hand, holds the holding piece 30 with the other hand, and operates the driving assembly 40 to enable the device to reach the off state, at this time, the tangential line communicating section 1202 and the limit communicating section 2202 are staggered, and the driving assembly 40 can drive the limit pipe 20 to move along the axial direction of the holding piece 30 so as to cut off the fixed end of the slipknot, so that the device and the slipknot can be withdrawn; when the operation fails, the occluder is withdrawn from the body by pulling the movable end of the slipknot with one hand of the operator (or doctor) and withdrawing the occluder from the body together with the other hand holding the holding member 30 (the device is in the off state at this time, and the fixed end of the slipknot is clamped in the fixed end limiting hole 220).
In some embodiments, as shown in fig. 3, the tangential communication section 1202 is located at an end of the tangential tube 10 remote from the drive assembly 40, the tangential communication section 1202 extends axially of the tangential tube 10, and the tangential bore section 1201 extends circumferentially of the tangential tube 10 and communicates with the tangential communication section 1202.
In some embodiments, as shown in fig. 5, the spacing communicating section 2202 is located at an end of the spacing tube 20 remote from the drive assembly 40, the spacing communicating section 2202 extends along an axial direction of the spacing tube 20, the spacing hole section 2201 extends along a circumferential direction of the spacing tube 20 and is in communication with the spacing communicating section 2202, wherein a height of the tangential hole section 1201 is greater than a height of the spacing hole section 2201.

It should be noted that, a cutting edge is disposed on a side wall of the tangential hole section 1201 near to the side of the driving assembly 40, so that in the off state, the driving assembly 40 can drive the limiting tube 20 to move along the axial direction of the grip member 30, and the fixed end of the slipknot is cut off by the cutting edge on the tangential hole section 1201.
In some embodiments, as shown in fig. 1, 8, the grip 30 includes: the handle 310 is provided with a communication station 720 and a shut-off station 710, wherein the communication station 720 and the shut-off station 710 are communicated through a connecting channel 730, the communication station 720 and the shut-off station 710 extend along the axial direction of the handle 310, and the connecting channel 730 extends along the circumferential direction of the handle 310; a connector 320 having one end connected to the handle 310 and the other end connected to the tangential pipe 10.

In some embodiments, the drive assembly 40 further includes a transition piece 440, and the drive member 430 is coupled to the spacing tube 20 via the transition piece 440.
It should be noted that, since the outer dimension of the driving member 430 may not match the inner dimension of the limiting tube 20, a transition member 440 may be disposed and connected to the driving member 430 and the limiting tube 20 through the transition member 440.
In some embodiments, as shown in fig. 6 and 7, the pre-buried knotting and delivering and cutting device for interventional operation further comprises a fixed plug 50, wherein the fixed plug 50 is connected with one end of the cutting tube 10 away from the driving assembly 40, a guide groove 530 is arranged at the edge of the fixed plug 50, a bearing groove 510 is arranged on the fixed plug 50, and a threading hole 520 is arranged on the bearing groove 510; wherein, the threading hole 520 is used for threading the movable end of the slipknot, the guiding slot 530 is communicated with the tangential line communicating section 1202, and in the communicating state, the fixed end of the slipknot can be pulled to the limiting hole section 2201 through the guiding slot 530.
In some embodiments, the diameter of the threading aperture 520 is 0.1mm-0.6mm.
It should be noted that, by setting the fixing plug 50 and setting the supporting groove 510 on the fixing plug 50, the slipknot can be placed on the supporting groove 510, the movable end of the slipknot passes through the threading hole 520 and then passes through the movable end limiting hole 210 and the movable end tangential hole 110, so that the problem that the slipknot can shake randomly when the slipknot is placed in the limiting tube 20 can be avoided, and the diameter of the threading hole 520 is generally smaller than that of the slipknot, so that the slipknot cannot pass through the threading hole 520, and after the fixing plug 50 is set, the guiding groove 530 is set for conveniently pulling the fixed end of the slipknot to the limiting hole section 2201.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
