Problems solved by technology

Most of these treatments require general anesthesia, and severe bleeding may occur during the operation
In addition, due to the weak tolerance of older patients, the above treatment methods may also cause retrograde ejaculation in patients.
[0004] The method of minimally invasive interventional therapy is to introduce a stent and use the stent to support the prostate tissue to form a channel and realize urination. The stent used in the prior art generally has the problem of long implantation time and easy displacement

Embodiment 1

[0051] figure 1 and figure 2 A schematic structural view of the medical implant 10 provided in this embodiment is shown. Such as figure 1 and figure 2 As shown, the medical implant 10 is configured to be radially contractable or expandable. In the following description of the shape of the medical implant 10 , unless otherwise specified, it means that the medical implant 10 is in an expanded state.

[0052] The medical implant 10 includes a stent 100 , the stent 100 includes at least three struts 110 for supporting human tissue, and at least three struts 110 are arranged at intervals along the circumference of the stent 100 . Each of the struts 110 extends along the axial direction of the stent 100 , and the proximal ends of all the struts 110 are gathered and connected to each other, and the distal ends of all the struts 110 are gathered and connected to each other. In this way, when the medical implant 10 is in the expanded state, each strut 110 may include a first tra...

Embodiment 2

[0069] Such as Figure 10 As shown, this embodiment also provides a medical implant 10. The difference between this embodiment and Embodiment 1 is that the entire structure of each strut 110 is wound by at least two strands of the support wire In other words, on each of the struts 110 , at least two strands of the support wires are wound to form the first transition section 111 , the strut section 112 and the second transition section 113 .

[0070] In this embodiment, the bracket 100 may not include the reinforcing member.

Embodiment 3

[0072] This embodiment provides a medical device 1, such as Figure 5 As shown, the medical device 1 includes a medical implant, a first catheter 20 and a pull wire 30, and the medical implant is the medical implant 10 provided in Embodiment 1 or Embodiment 2. The distal end of the first conduit 20 is used to detachably connect with the proximal end of the medical implant 10 , and the distal end of the first conduit 20 and the medical implant 10 remain circumferentially relatively stationary , so that when the first conduit 20 rotates, the medical implant 10 can be driven to rotate synchronously around its axis. The distal end of the pull wire 30 is connected to the proximal end of the medical implant 10, and the proximal end of the pull wire 30 passes through the lumen of the first catheter 20, and the proximal end of the pull wire 30 forms a stop The limiting portion is located outside the proximal end of the first conduit 20 , and the limiting portion is used to prevent th...

Abstract

The invention provides a medical implant and a medical device. The medical device comprises the medical implant, and the medical implant is configured to be capable of contracting or expanding in the radial direction; the medical implant comprises a support, the support comprises at least three supporting columns used for supporting human tissue, the at least three supporting columns are arranged in the circumferential direction of the support at intervals, the supporting columns extend in the axial direction of the support, the near ends of all the supporting columns are folded and connected with one another, and the far ends of all the supporting columns are folded and connected with one another; and at least part of the structure of the support column is formed by mutually winding more than two strands of support wires. The medical implant is used for being implanted into the urethra, supporting the prostate tissue and forming a plurality of discrete supporting points so as to expand the urethra, stimulation to the prostate tissue can be reduced, and the positioning stability can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical implant and a medical device. Background technique [0002] The treatment methods for benign prostatic hyperplasia (BPH) include conventional surgery, laser therapy and minimally invasive interventional therapy. Among them, conventional surgical treatment includes transurethral resection of the prostate (TURP), transurethral incision of the prostate (TUIP), and open prostatectomy. At present, TURP is still the "gold standard" in the treatment of BPH. The curative effects of various surgical methods are similar or similar to TURP, but the scope of application and complications are different. As an alternative to TURP and TUIP, transurethral electrovaporization of the prostate (TUVP) and transurethral bipolar resection of the prostate (PKRP) are also currently used in surgical treatment. [0003] All the above-mentioned treatment methods can improve the urinary ...
