Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a prostate suspension device. Background Art
[0002] Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men, and the incidence is increasing with the aging of the global population. The incidence of BPH increases with age, but there may not be clinical symptoms when there are hyperplastic lesions. The incidence rate in urban areas is higher than in rural areas, and racial differences also affect the degree of hyperplasia.
[0003] The prostate gland is located below the bladder. The tube that carries urine from the bladder to the penis (urethra) passes through the center of the prostate gland. The prostate gland continues to grow throughout most men's lives. In some men, the prostate capsule surrounding the prostate gland may prevent the prostate gland from enlarging further, which can cause the inner area of the prostate gland to press against the urethra. This pressure on the urethra increases the resistance to urine flowing through the area of the urethra surrounded by the prostate gland. Therefore, the bladder must exert more pressure to force urine through the increased urethral resistance. Chronic overstraining can cause the muscle wall of the bladder to remodel and become stiffer. This increased urethral resistance and increased stiffness of the urine stream, as well as hypertrophy of the bladder wall, can lead to a variety of lower urinary tract symptoms that can significantly reduce a person's quality of life. These symptoms include a weak or intermittent urine stream when urinating, straining when urinating, hesitation before starting to urinate, a feeling that the bladder is not completely empty even after urinating, dribbling or leaking urine at the end of urination, especially increased frequency of urination at night, and urgency to urinate.
[0004] Prostatic urethral lift (PUL) is a new, nearly non-invasive implantable prostate hyperplasia treatment for the treatment of lower urinary tract symptoms caused by benign prostatic hyperplasia in men. This treatment uses an instrument to push back the prostate hyperplasia lobe through the urethra, and a tiny device (anchor component) is permanently implanted to fix the hyperplastic prostate lobe in the retracted position, thereby maintaining the integrity of the prostate and restoring the urethra. It effectively relieves urine flow and greatly improves frequent or difficult urination caused by prostate hyperplasia.
[0005] The prostate suspension device is a medical device based on the principle of PUL technology. The product consists of a delivery device and an anchor component. The anchor component is located inside the delivery device. The delivery device is equipped with a power source, and the deployment of the anchor component is achieved by mechanical transmission. The anchor component includes a first anchor component, a second anchor component and a suture, and the first anchor component and the second anchor component are connected by sutures. Specifically, the product is passed through the urethra to the prostate segment urethra under cystoscope visualization, and a suitable puncture point is selected in the prostate segment urethra to fully compress the prostate tissue, and the puncture needle is fired to the outside of the prostate capsule. While retrieving the puncture needle, the first anchor component is released on the outside of the prostate capsule, and the second anchor component is released in the prostate segment urethra. The first anchor component and the second anchor component are connected by sutures to form an "I"-shaped structure, which effectively suspends the hyperplastic prostate tissue. The anchor components need to be implanted in pairs, usually 4 to 6 sets of rivet systems are implanted, which can fully suspend the prostate segment urethra and relieve urethral obstruction. It has the advantages of minimally invasive, retaining sexual function, local anesthesia surgery, and fast recovery.
[0006] When the prostate suspension device in the prior art is used for surgical implantation, the clinician cannot directly observe the fixation of the first anchor component on one side of the prostate capsule, and the doctor cannot confirm the expected therapeutic effect of each implantation on site.

[0028] See also Figure 5-Figure 6 In some embodiments, the thread assembly 220 includes a suture slider 223, a suture 221, and a suture support tube 222; the suture support tube 222 is connected to the suture slider 223, the suture 221 is passed through the suture support tube 222 and is fixedly connected to the suture support tube 222, and the first anchor component 261 is fixedly connected to the distal end of the suture 221. The suture slider 223 is disposed between the guide plate 211 and the replacement chamber inner shell 210, and is slidably connected to the guide plate 211 and the replacement chamber inner shell 210.
[0029] Further, the suture slider 223 is connected to the wire driver 120. Specifically, the suture slider 223 has a first protrusion 224 on the side opposite to the wire driver 120. The wire driver 120 is provided with a first slot 121 corresponding to the first protrusion 224. The first protrusion 224 and the first slot 121 are configured such that when the replacement chamber 200 and the handle 100 are positioned and fixedly combined, the first protrusion 224 is inserted into the first slot 121. In this embodiment, the wire assembly 220 is connected by the suture slider 223 and the wire driver 120, so that the wire assembly 220 and the wire driver 120 are linked.
[0030] See also Figure 5-Figure 7 In some embodiments, the delivery device 1 includes a needle drive 130 and a needle assembly 230; in this embodiment, the needle drive 130 is arranged inside the handle 100, and the needle assembly 230 is arranged inside the replacement chamber 200; the needle drive 130 is slidably connected to the intermediate plate 111; the needle drive 130 is connected to the needle assembly 230, and the needle drive 130 is used to drive the needle assembly 230 to perform linear reciprocating motion; specifically, the needle assembly 230 includes a needle The needle rod 231 has a delivery needle 232 connected to its distal end, and a needle slider 233 connected to its proximal end; further, the needle slider 233 has a second protruding piece 234 on a side opposite to the needle driving member 130, and correspondingly, the needle driving member 130 has a second slot 131, and the second protruding piece 234 and the second slot 131 are configured such that when the replacement chamber 200 and the handle 100 are positioned and fixedly combined, the second protruding piece 234 is inserted into the second slot 131. The needle slider 233 is disposed between the guide plate 211 and the replacement chamber inner shell 210, and is slidably connected to the guide plate 211 and the replacement chamber inner shell 210.
[0031] It should be noted that before the prostate suspension instrument is activated, the first anchor component 261 and the suture portion 263 are engaged with each other and accommodated in the needle assembly 230, and the second anchor component 262 is disposed in the intervention rod 212. After the first anchor component 261 and the suture portion 263 have been placed in the prostate tissue, the second anchor component 262 is firmly engaged with the suture portion 263 to form a fully assembled anchor assembly 260.
[0032] Please still refer to Figure 5In some embodiments, the replacement capsule 200 further includes a push rod assembly 240 and a cutting assembly 250. The push rod assembly 240 is used to push the second anchor component 262 to move toward the distal end of the intervention rod 212 and finally connect with the suture 221, and to separate the second anchor component 262 from the intervention rod 212 and enter the prostatic urethra segment. The cutting assembly 250 is used to cut the suture 221 after the second anchor component 262 is deployed.
[0033] See also Figure 8 In this example, the needle drive 130 is connected to the wire drive 120 via a constant force spring 132, and the constant force spring 132 is used to keep the tension of the suture 221 constant. Specifically, after the anchor assembly 260 is implanted into the prostate tissue, the tension of the suture portion 263 between the first anchor component 261 and the second anchor component 262 will change with the size and hardness of the prostate, thereby causing the anchor assembly 260 to have different lifting effects on the prostate. In this embodiment, by setting the constant force spring 132, before the suture 221 is cut, the force of the constant force spring 132 in the handle 100 acts on the suture 221 through the intermediate component, ensuring that the tension of the suture portion 263 remains consistent after cutting.
[0034] Please still refer to Figure 8 In some embodiments, the indicating component 140 includes a connecting portion 141 and an indicating portion 142; the indicating component 140 is fixedly connected to the wire driving component 120 through the connecting portion 141, the connecting portion 141 is a triangular structure, the indicating portion 142 is located at the top of the connecting portion 141, and the bottom of the indicating portion 142 is slidably connected to the intermediate plate 111.
[0035] See also Figure 9-10 In some embodiments, the conveying device 1 includes a housing, the intermediate plate 111 is arranged inside the housing, the intermediate plate 111 cooperates with the housing to form a guide groove 144, and the lower end of the indicating part 142 is provided with a sliding part 143 that cooperates and slides with the guide groove 144. Specifically, the housing includes the left housing 110 and the right housing 112, and the intermediate plate 111 cooperates with the right housing 112 to form the guide groove 144. In this embodiment, the stability of the movement of the indicating part 140 is improved by the cooperation of the sliding part 143 and the guide groove 144.
[0036] The wire drive component 120 is located between the left shell body 110 and the middle plate 111. In order to make the indicating part 142 of the indicating component 140 be located on the central axis of the handle 100, a crank arm is formed between the connecting part 141 and the indicating part 142 of the indicating component 140. The crank arm is "L" shaped. The design of the crank arm makes the indicating part 142 exactly located on the central axis of the handle 100, thereby increasing the overall aesthetics of the conveying device 1.
[0037] See also Figure 8-Figure 9 In some embodiments, the conveying device 1 is further provided with a transparent protective shell 150, which is arranged on the outside of the indicating part 142 to protect the indicating part 140. Furthermore, the transparent protective shell 150 is fixedly mounted on the top of the shell, and the movement of the indicating part 142 can be clearly observed through the transparent shell.
[0038] See also Fig.11 In some embodiments, the transparent protective shell 150 is provided with an indicative mark for cooperating with the indicating component 140 to assist in determining the fixation of the first anchor component 261. Further, the indicative mark includes a first mark 152 and a second mark 153, wherein the first mark 152 is located on the side of the transparent protective shell 150 close to the proximal end of the intervention rod 212, and the second mark 153 is located on the side of the transparent protective shell 150 close to the distal end of the intervention rod 212.
[0039] In some embodiments, the conveying device 1 is provided with a scale (not shown in the drawings), which is arranged on one side of the indicating component 140, and is used to cooperate with the indicating component 140 to assist in determining the fixing status of the first anchor component 261. In this embodiment, the scale is arranged on the top of the transparent protective shell 150, and is located between the first mark 152 and the second mark 153.
[0040] In other embodiments, the scale is disposed on the left housing 110 or the right housing 112 .
[0041] After the replacement chamber 200 is installed on the handle 100 and before it is activated, the indicator 142 is located at the first mark 152 position.
[0042] The anchor assembly 260 is deployed through a series of steps. The needle assembly 230 is driven by the needle driver 130 to slide toward the distal end of the intervention rod 212. The delivery needle 232 extends from the outlet at the distal end of the intervention rod 212 to a fully extended position, so that at least a portion of the delivery needle 232 penetrates the patient's prostate capsule. The first anchor component 261 and the distal end of the suture 221 are contained in the delivery needle 232 and move together with the delivery needle 232 to penetrate the prostate tissue. During this process, the indicator portion 142 of the indicator component 140 moves from the first mark 152 to the second mark 153.
[0043] Next, while the first anchor member 261 and the distal end of the suture 221 remain in the proper position outside the prostate capsule, the needle assembly 230 moves toward the proximal end of the intervention rod 212, so that the delivery needle 232 moves to a partially retracted position, that is, the delivery needle 232 moves proximally relative to its fully extended position, but has not yet been fully retracted into the intervention rod 212. The wire support tube helps to maintain the distal position of the first anchor member 261 and the suture 221 while the needle assembly 230 moves toward the proximal end of the intervention rod 212. Therefore, the first anchor member 261 and the distal end of the suture 221 remain near the surface of the prostate tissue and are no longer in the delivery needle 232. Therefore, during this process, the indicator member 140 remains stationary. That is, the indicator portion 142 is still located at the second mark 153.
[0044] In the next step, the needle assembly 230 is further moved proximally to be retracted into the intervention rod 212, while the wire assembly 220 is also moved proximally. The first anchor component 261 is pulled against the tissue surface, which causes the first anchor component 261 to rotate around its connection with the suture 221, so that the first anchor component 261 is now transverse to the distal end of the suture 221. In this process, as the wire assembly 220 moves toward its proximal end, the indicator component 140 synchronously moves toward the direction close to the first mark 152. When the tension of the suture 221 reaches the calibration value of the constant force spring 132, the wire assembly 220 stops moving, and the indicator component 140 stops moving synchronously. The doctor can judge whether the deployment of the first anchor component 261 is in place based on the position where the indicator component 140 stops moving, combined with clinical experience, and further judge whether the operation can achieve the expected therapeutic effect.
[0045] In the next step, the push rod assembly 240 within the handle 100 will be actuated to cause the second anchor component 262 to engage the suture 221, which action defines a suture portion 263 that becomes part of the final anchor assembly 260 implanted in the patient. At this point, the anchor assembly 260 is now completely separated from the cartridge and handle 100 system. Please refer to Figure 4 , Fig.12 , Fig.13 , Fig.14It should be noted that the handle 100 is provided with a driving mechanism for driving a series of actions in the replacement capsule 200, and the driving mechanism includes a trigger member 160, a driving gear 161, a ratchet 162 and a cam 163. The trigger member 160 interacts with the cam 163 through the driving gear 161 and the ratchet 162. The cam 163 interacts with other mechanisms in the handle 100 (including the wire drive member 120 and the needle drive member 130) to promote the movement of various components in the replacement capsule 200 (such as the needle assembly 230, the wire assembly 220, the push rod assembly 240 and the cutting assembly).
[0046] Please refer to Fig.15 The replacement cabin also includes a replacement cabin shell 213 and an unlocking switch 270. The replacement cabin shell 213 is connected to the guide plate 211 and the replacement cabin inner shell 210 to form a replacement cabin body. The unlocking switch 270 is connected to the replacement cabin shell 213. The unlocking switch 270 includes a knob 271. The knob 271 is provided with an operating handle 272 for easy operation. The operating handle 272 has symmetrically arranged concave structures 273 on both sides. The concave structure 273 facilitates the removal of the replacement cabin from the handle after unlocking.
[0047] In summary, the prostate suspension device proposed by the present invention provides an indication component 140 on the handle 100, and the indication component 140 is linked through multiple intermediate components, so that the clinician can judge the fixation of the first anchor component 261 on one side of the prostate capsule by observing the movement of the indication component 140. Therefore, the present invention effectively overcomes the defects of the prior art and has a high industrial utilization value.
[0048] The above is only a specific implementation of the embodiment of the present application, but the protection scope of the embodiment of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed in the embodiment of the present application should be included in the protection scope of the embodiment of the present application.
