Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an implant delivery tube, a delivery device and a medical equipment. Background Art

[0002] Benign prostatic hyperplasia (BPH) is one of the most common medical diseases affecting men, especially older men. It causes the internal area of ​​the prostate to squeeze the urethra, leading to clinical symptoms such as urinary retention, renal insufficiency, recurrent urinary tract infections, incontinence, hematuria and bladder stones.

[0003] Currently, BPH can be treated surgically, for example, by inserting an implant into the human body through a device, using the supporting properties of the implant to separate the two lobes of the prostate so that it no longer blocks the urethra. Specifically, this type of device first uses a puncture needle to implant the implant into the human body, then withdraws the puncture needle, releases the proximal anchor again, and finally uses a shearing and pushing mechanism to shear off the excess connectors on the implant.

[0004] When implanting an implant, the existing delivery device installs a pair of implants in the delivery tube, and uses a puncture needle to implant the implant into the human body under the endoscope. When implanting the second pair of implants, the endoscope needs to be removed from the delivery tube and installed in a new delivery tube. This operation wastes a lot of surgical time, and the endoscope needs to be removed and installed multiple times during the entire operation, increasing the risk of endoscope damage.

[0005] Therefore, it is necessary to provide an implant delivery tube, a delivery device and a medical device, which do not require the endoscope lens to be pulled out multiple times during the implantation process, thereby avoiding damage to the endoscope lens, shortening the surgical operation time and alleviating pain. Utility Model Content

[0007] The utility model provides an implant delivery tube, which is used to provide a channel for accommodating an implant and an endoscope. The implant comprises a distal anchor, a connector and a proximal anchor. The distal anchor and the connector are connected to each other and are arranged in a puncture needle. The utility model is characterized in that the implant delivery tube comprises a first channel tube, a second channel tube and a front channel tube. The distal ends of the first channel tube and the second channel tube are both connected to the front channel tube.

[0008] The first channel tube is arranged in parallel with the second channel tube, and a gap is left between the first channel tube and the second channel tube.

[0009] The first channel tube is used for the puncture needle to pass through; the second channel tube is used for the proximal anchor to pass through; and the gap allows the endoscope channel tube to be inserted.

[0010] Optionally, the implant delivery tube further comprises a connecting tube, which is disposed in the gap and connects the first channel tube and the second channel tube, and one side of the connecting tube is axially extended with an opening allowing the endoscope channel tube to be inserted.

[0011] Optionally, the cross-section of the inner wall of the connecting pipe is U-shaped, polygonal or arc-shaped.

[0012] Optionally, the connection method of the connecting pipe, the first channel pipe and the second channel pipe is bonding, welding or riveting.

[0013] Optionally, the connecting pipe is integrally formed with the first channel pipe and the second channel pipe.

[0014] Optionally, the front channel tube has an arc-shaped channel, and the first channel tube is connected to the arc-shaped channel to form a puncture channel for the puncture needle to pass through.

[0015] Optionally, the second channel tube is provided with an avoidance opening at a position corresponding to the outlet of the puncture channel.

[0019] Compared with the prior art, the technical solution of the utility model has beneficial effects.

[0020] For example, the implant delivery tube is provided with a space that can accommodate the endoscope channel tube and allow the endoscope channel tube to be embedded from the side, thereby realizing the rapid separation of the implant delivery tube and the endoscope channel tube. There is no need to remove the endoscope from the end of the delivery tube and then install it, thus avoiding the risk of lens damage caused by replacing the endoscope and shortening the surgical operation time. At the same time, the implant delivery tube has a simple and reliable structure and is easy to process, which is conducive to cost control.
