Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and particularly relates to a prostate bundle and a prostate bundle body transmitting device of a barbed wire. Background Art

[0002] The prostate gland is an important part of the male reproductive system. Its main function is to secrete prostatic fluid, an alkaline fluid that accounts for about 30% of semen and provides protection for sperm, helping them survive the acidic vaginal environment. Enzymes in prostatic fluid also help liquefy semen, ensuring that sperm can swim freely. In addition, the prostate gland participates in the mechanism of controlling urine flow through its position around the urethra. Therefore, the health of the prostate gland is crucial to the function of the male reproductive and urinary systems.

[0003] Benign prostatic hyperplasia (BPH) refers to a benign increase in the size of the prostate gland, which often occurs in middle-aged and older men. The enlarged prostate may compress the urethra, causing obstruction of urine flow, because the prostate gland surrounds part of the urethra. As the prostate gland increases in size, it begins to exert pressure on the urethra, thereby affecting the flow of urine. In addition, BPH may cause a range of urinary tract symptoms, such as frequent urination, urgency, increased nocturia, weak urine stream, and dribbling. If left untreated, it may affect quality of life and cause sleep disorders and emotional problems.

[0004] Surgical procedures used to treat BPH symptoms include transurethral resection of the prostate (TURP), transurethral electrovaporization of the prostate (TVP), transurethral incision of the prostate (TUIP), laser prostatectomy, and open prostatectomy. All of the above treatments have varying degrees of risk: transurethral resection of the prostate requires general anesthesia or spinal anesthesia for resection, causing greater tissue damage; transurethral electrovaporization of the prostate requires general anesthesia or spinal anesthesia to heat the prostate tissue, and the patient needs to endure great pain; transurethral incision of the prostate requires general anesthesia or spinal anesthesia to make one or more incisions in the muscles of the bladder neck and multiple wounds in the related tissues; laser prostatectomy is performed by laser ablation or cutting / excision, and the patient needs to endure great pain; open prostatectomy requires general anesthesia and is removed through an incision in the abdomen or perineum. This surgery is mostly used for patients with giant (greater than about 100g) prostate hyperplasia.

[0005] CN101795641A relates to a prostate multi-brake trigger anchoring delivery system, which introduces a method of puncturing the prostate tissue with its anchoring assembly through urethral minimally invasive surgery to produce physical compression and widening of the urethra on the inner and outer sides of the prostate tissue. The delivery system is implemented as follows: the first trigger is pulled to cause the needle assembly to be pushed into the patient's body to the interventional site. The second trigger is pulled to complete the deployment of the first anchoring component of the anchoring assembly at the interventional site, and the third trigger is pulled to promote the withdrawal of the needle assembly. The fourth trigger is pressed down to promote the assembly and release of the second component of the anchoring assembly at the interventional site. The delivery system has a complex structure that is not conducive to production, and many steps are not conducive to the rapid completion of the operation. The distal anchor needs to pierce the outside of the prostate, resulting in the rupture of the inner and outer capsules of the prostate, causing greater damage. In addition, the beam line is a smooth material with poor bonding with tissues, and stainless steel foreign bodies need to be left in the urethra to fix the beam line, and the anchoring assembly is a non-absorbent material, which is retained in the body in the form of foreign bodies for a long time, which is easy to cause body rejection reactions. Summary of the invention

[0006] The present invention provides a prostate wire harness with barbs and an implantation device, which are used to solve the above-mentioned technical problems.

[0007] The technical solution adopted by the present invention is:

[0008] A frontal wire harness with barbs comprises a wire harness, wherein barbs facing opposite directions are arranged on the wire harness with a preset position as the center, and the barbs all face the center position.

[0009] Furthermore, the line material is made of a human body absorbable material, and the human body absorbable material includes any one of polydioxanone, polyglycolic acid, polylactic acid, polycaprolactone, polylactic acid-hydroxyacetic acid, glycolide-lactide, glycolide-ε-caprolactone and polylactide-polyethylene glycol.

[0010] Furthermore, the line material is made of a material that is not absorbable by the human body, and the non-absorbable material includes any one of polypropylene, polypropylene / polyethylene-95 / 5, polyamide, polyester, polyvinylidene chloride, polyvinylidene fluoride and polyethylene terephthalate.

[0011] A prostate beam implantation device comprises a trigger device and a transmission device. The trigger device comprises an instrument storage device, a spring, a trigger, and a mechanism connecting the spring and the instrument storage device. The transmission device comprises a beam, a puncture tube, a gun barrel, a cavity tube, a slideway and a locking buckle. The depth of puncturing tissue can be controlled. A cavity tube for introducing an endoscope is provided, which can be operated by the trigger gear position. The puncture tube has a blunt mouth.

[0012] Furthermore, the trigger device includes an instrument storage device, a spring, a trigger, a connecting spring and a bearing shaft of the instrument storage device.

[0013] Furthermore, the instrument storage device is circular or polygonal, and is connected to the puncture tube for puncturing prostate tissue, and the depth of puncturing tissue can be controlled by rotating the instrument storage device.

[0014] Furthermore, the spring is a constant force spring or a common spring, which is connected to the lever through a bearing shaft, and the lever buckle of different gears is pulled to control the placement and use of the cable harness.

[0015] Furthermore, the trigger device includes: a wire harness, a puncture tube, a gun barrel, a cavity tube, a slideway, and a locking buckle.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The prostate bundle system of barbed wires is placed in the prostate tissue through the urethra. The instrument storage device allows the puncture tube to pierce the inner wall of the prostate tissue, and the bundle is delivered to the prostate tissue. The barbs in the opposite direction of the bundle are used to shrink the prostate. The characteristic is that the puncture tube has a blunt tip and does not damage the outer wall tissue of the prostate during puncture, which greatly reduces the damage of the surgery to the prostate tissue; the bundle does not require a urethral fixation device, and there is no foreign matter in the urethra.

[0018] The wire is processed with barbs facing opposite directions on the wire body with the appropriate position of the wire as the center, and the barbs all face the center position. As for the prostate tissue, it can resist the repositioning of the prostate tissue to achieve the effect of contracting the prostate tissue and widening the urethra.

[0019] The beam material is a material that can be absorbed by the human body or a non-absorbable material. The absorbable materials include but are not limited to polymers such as polydioxanone, polyglycolic acid, polylactic acid, polycaprolactone, copolymers such as polylactic acid-glycolic acid, glycolide-lactide, glycolide-ε-caprolactone, polylactide-polyethylene glycol, and absorbable polymers or copolymer materials; non-absorbable materials include but are not limited to polypropylene, polypropylene / polyethylene (95 / 5), polyamide, polyester, polyvinylidene chloride, polyvinylidene fluoride, etc., non-absorbable polymers or copolymer materials, silk and other non-absorbable materials.

[0020] 2. The structure of the instrument storage device is circular or polygonal, and its characteristic is that during laparoscopic surgery, the doctor can manually push the length of the puncture tube according to the size of prostatic hyperplasia, so that the puncture length meets the surgical expectations and is convenient for surgical operation.

[0021] 3. The parts of the trigger device that are in contact with human tissue are separated: the puncture tube and the cavity tube are installed on the transmission device in the form of a buckle, which is conducive to rapid disassembly and installation, and allows the transmission device to be reused.

[0022] 4. During the operation, put the endoscope into the cavity tube, observe the depth of puncture required, use the instrument storage device of the trigger device to drive the puncture tube to puncture the prostate tissue to the appropriate depth, and after the puncture is completed, pull the first gear of the trigger to trigger the beam line to eject into the prostate tissue, and use the front end of the transmission device to squeeze the prostate tissue to narrow it to the appropriate position. The barbs on the beam line body and the restoring force of the prostate tissue produce a counterforce, so that the prostate tissue keeps contracting and widening the urethra, and the rotating instrument storage device drives the puncture tube back into the loading pipe. Pull the button to the second gear to make the cutting switch cut off the excess beam line. At this time, the barbs on the front and back sides are used to bind the prostate in a compressed state. The prostate barb beam system can smoothly and quickly place the beam line with bidirectional barbs into the prostate. The operation is convenient, which reduces the pain of the patient during the operation and shortens the operation time. The puncture tube and the cavity tube are installed on the transmission device in the form of buckles, which is conducive to rapid disassembly and installation and can make the transmission device reused.

[0027] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 3 , the present invention provides a front-row harness with barbs, characterized in that: it comprises a harness, both sides of which are provided with a plurality of barbs facing in opposite directions, and the harnesses are sequentially connected to form a line;

[0029] After the Speedwire is implanted in the prostate, the prostate gland is constricted using two opposing barbs.

[0030] Preferably, the beam material is a human body absorbable material or a non-absorbable material. The absorbable material includes but is not limited to polymers such as polydioxanone, polyglycolic acid, polylactic acid, polycaprolactone, copolymers such as polylactic acid-hydroxyacetic acid, glycolide-lactide, glycolide-ε-caprolactone, polylactide-polyethylene glycol, and absorbable polymers or copolymer materials.

[0031] Preferably, the non-absorbable materials include but are not limited to polypropylene, polypropylene / polyethylene (9 puncture tube 5 / 5), polyamide, polyester, polyvinylidene chloride, polyvinylidene fluoride, etc. and non-absorbable polymer or copolymer materials, silk and other non-absorbable materials.

[0032] A prostate beam implantation device includes a trigger device and a transmission device, the trigger device includes an instrument storage device 3, a spring 4, a pull button 5, and a mechanism connecting the spring 4 and the instrument storage device 3, the transmission device includes a beam, a puncture tube, a gun barrel, a cavity tube, a slideway and a locking buckle, characterized in that: the depth of puncturing tissue can be controlled, a cavity tube for introducing an endoscope is provided, and the puncture tube can be operated by the pull button 5 gear position, the puncture tube is a blunt mouth, and when used, the endoscope is introduced into the prostate tissue through the cavity tube in the transmission device, so that it has a visualization effect, and after the endoscope is placed, the locking buckle is pulled to fix it in the prostate barb beam system. The instrument storage device 3 in the trigger device is a polygonal structure connected to the puncture tube, and each rotation of one side of the instrument storage device 3 will push the puncture tube to slide forward along the gun barrel, and the doctor can control the length of rotation according to the size of the prostate hyperplasia tissue to be treated. When the puncture tube pierces the prostate hyperplasia tissue to a suitable depth, the pull button 5 is pulled to the first gear to eject the bundle into the prostate hyperplasia tissue, and the front end of the transmission device is used to squeeze the prostate hyperplasia tissue to shrink the prostate tissue to a suitable position and then release it. At this time, the barbs on the bundle produce a counterforce to keep the prostate hyperplasia tissue in the shrink position, thereby achieving the effect of expanding the urethra. After completing the above operation, the pull button 5 is pulled to the second gear to slide the device out of the slideway, and the bundle is cut. The doctor can select multiple shrink positions according to the size of the prostate tissue hyperplasia, and finally achieve the effect of expanding the urethra.

[0033] Preferably, the wire material is a human body absorbable material or non-absorbable material. The absorbable material includes but is not limited to polymers such as polydioxanone, polyglycolic acid, polylactic acid, polycaprolactone, and copolymers such as polylactic acid-glycolic acid, glycolide-lactide, glycolide-ε-caprolactone, polylactide-polyethylene glycol, and absorbable polymers or copolymer materials; the non-absorbable material includes but is not limited to polypropylene, polypropylene / polyethylene (9 puncture tube 5 / 5), polyamide, polyester, polyvinylidene chloride, polyvinylidene fluoride, and non-absorbable polymers or copolymer materials, silk and other non-absorbable materials;

[0034] Preferably, the instrument storage device 3 is a polygonal structure, generally a 6-10-sided polygon, and most preferably a 10-sided polygon.

[0035] The present invention considers that the trigger device pushes the components of the transmission system, the puncture tube component is pushed through the instrument storage device 3 and triggers the beam to be transferred to the prostate tissue. In the context of prostate treatment, the present invention completes the compression of the prostate and the opening of the prostate urethra, removes the transmission device of the intervention site, and applies tension at both ends of the implanted beam. Once implanted, the transmission device component of the present invention completes the desired tissue manipulation, compression or retraction, and cooperates with the target anatomical structure to provide a traumatic support structure. In the case where the transmission device is properly placed, the delicate or soft tissue in the area is contracted by the beam. Ultimately, over time, the beam is degraded and absorbed, and the natural tissue can grow to maintain the corresponding function of the prostate. This cooperation with the target tissue promotes healing and avoids unwanted side effects such as calcification or infection of the interventional site. In addition, in addition to the intention of cooperating with the natural tissue anatomical structure, the present invention also considers methods for accelerating healing or reducing scars. Ways in which healing can be improved may include the use of abrasive materials, textured connectors, biology, and drugs. It has been observed that placing the transmission component in various desired positions within the anatomical structure can produce the best results. For example, when treating the prostate, a portion of the delivery device can be placed within the urethra. Endoscopic visualization placed within the lumen tube effectively maintains open anatomy when viewed along the axis of the urethra and can also facilitate traditional assembly closure in the anatomy proximal to the bladder and the junction area where the ejaculatory duct connects to the urethra.

[0036] In addition, it is contemplated that all components of the delivery device or selected portions thereof may be coated with therapeutic or diagnostic substances (e.g., therapeutic drugs, anti-inflammatory and antibacterial substances), the coating may have varying or specific thicknesses or concentrations, and the substances that may be coated include, but are not limited to, 5-a-reductase that causes a reduction in prostate size, adrenergic receptor blockers, smooth muscle relaxants, agents that inhibit the conversion of testosterone to dihydrotestosterone, anti-inflammatory and antibacterial triclosan, chitosan, ibuprofen, voltaren, aspirin, paracetamol, etc.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
