Detailed Description

At present, the structure of the anchoring device commonly used in the treatment of minimally invasive wounds including prostatic stent can refer to fig. 1, and fig. 1 is a schematic structural diagram of the anchoring device in the prior art. The anchoring device 300 includes a proximal anchor 310, a distal anchor 330, and a connector 320. The distal end of the connector 320 is fixedly connected to the distal anchor 330, and the proximal end of the connector 320 is detachably and fixedly connected to the proximal anchor 310. The proximal anchor 310 comprises a proximal body 311 and a grip 312 fixedly connected to the proximal body 311. The gripping portion 312 may grip the connector 320 to limit movement of the connector 320 relative to the proximal anchor 310. When the clip 312 and connector 320 are disengaged from each other, the connector 320 and the proximal anchor 310 are disengaged from each other. Before such an anchoring device 300 is implanted in the anterior urethra, the gripping portion 312 of the proximal anchor 310 and the connecting element 320 are separated from each other, and after the anchoring device 300 is implanted, the gripping portion 312 of the proximal anchor 310 grips the connecting element 320 to restrict the connecting element 320 from moving relative to the proximal anchor 310.

The anchoring device mechanically separates the left and right prostate lobes after implantation in the urethra and pushes the prostatic hyperplasia tissue pressing the urethra back to the distal location to treat benign prostatic hyperplasia. The process of implanting the anchoring device 300 essentially comprises the steps of: first, the puncture needle 100 is implanted through the delivery device to puncture the prostate tissue through the puncture needle 100. Wherein the distal anchor 330 and the connector 320 fixedly attached to the distal anchor 330 are disposed in the needle 100. Next, the penetrating needle 100 is withdrawn to release the distal anchor 330, thereby anchoring the distal anchor 330 in the prostate tissue. Again, proximal anchor 310 is implanted with the delivery device to fixedly connect proximal anchor 310 to connector 320 and anchor proximal anchor 310 in the prostatic tissue, thereby completing implantation of anchor 300. The above-mentioned implantation method can be used to implant a plurality of anchoring devices 300 for a plurality of times according to actual needs, generally 4-6 anchoring devices are required to be implanted, and the schematic structural diagram of the plurality of anchoring devices 300 implanted into the urethra can be referred to fig. 2, and fig. 2 is a schematic structural diagram of the plurality of anchoring devices 300 implanted into the urethra in the prior art.

However, during implantation of the delivery device into the anchoring device 300, only one distal anchor 330 and one proximal anchor 310 can be released after a single loading of the delivery device. Thus, when multiple anchoring devices 300 are to be implanted, the delivery system may be withdrawn from the body after implantation of one anchoring device 300, reloaded into the body, and so on, until all anchoring devices 300 have been implanted. In this case, the delivery system enters the urethra multiple times, increasing the risk of urethral damage and complicating the procedure.

Based on this, the embodiment of the utility model provides a conveying system, conveying system includes pjncture needle, near-end transfer passage, near-end anchoring, connecting piece and two at least far-end anchorages, the quantity more than or equal to of far-end anchoring the quantity of connecting piece, far-end anchoring with the connecting piece loads in the pjncture needle, the connecting piece is established ties in proper order and is the threadiness, far-end anchoring is fixed the setting in proper order on the connecting piece, near-end anchoring loads in the near-end transfer passage. Through once loading two at least distal end anchorages and connecting piece in conveying system's pjncture needle to make conveying system implant urethra back, the pjncture needle can be punctured many times in succession, and a distal end anchor can be implanted in every puncture, and then need not to pack a distal end anchor and just withdraw from conveying system extracorporeally once, loads distal end anchor once more and gets into the human body once more, so, can avoid conveying system to get into the urethra repeatedly many times and lead to the urethra damage, and can simplify the operation.
