Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a prostate suspension device. Background Art

[0002] Benign prostatic hyperplasia (BPH) is one of the common diseases in middle-aged and elderly men, and its incidence is increasing with the aging of the global population. The incidence of benign prostatic hyperplasia increases with age, but there may be no clinical symptoms when there are hyperplastic lesions.

[0003] The prostate is located below the bladder. The duct (urethra) that transports urine from the bladder to the penis passes through the center of the prostate. The prostate in most men continues to grow throughout their lives. In some men, the prostatic capsule around the prostate may prevent the prostate from growing further, which causes the internal area of the prostate to compress the urethra. This increased pressure on the urethra increases the resistance to urine flow through the area of the urethra surrounded by the prostate. Therefore, the bladder must exert greater pressure to force urine through the increased urethral resistance. Chronic overexertion can cause the muscle wall of the bladder to remodel and become harder. This increased urethral resistance, increased urine flow hardness, and bladder wall hypertrophy can cause various lower urinary tract symptoms, which may seriously reduce the quality of life of patients. These symptoms include weak or intermittent urine flow during urination, straining during urination, hesitation before the start of urination, feeling that the bladder is not completely emptied even after urination, dribbling or leakage of urine at the end of urination, especially increased urination frequency at night and urgency.

[0004] Prostate urethral lift therapy (PUL) is a latest, nearly non-invasive implantable therapy for benign prostatic hyperplasia, used to treat lower urinary tract symptoms in men caused by benign prostatic hyperplasia. This therapy uses an instrument to push back the hyperplastic prostate lobe through the urethra, and at the same time permanently implants a tiny device (anchor assembly) to fix the hyperplastic prostate lobe in the retracted position, achieving the effect of keeping the prostate intact and restoring the urethra. It effectively relieves urine flow and greatly improves the frequency or obstruction caused by benign prostatic 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.

The guide plate 211 and the replacement cartridge 200 are configured to provide installation space for a plurality of components between the guide plate 211 and the inner housing 210 of the replacement cartridge. The wire assembly 220 is slidably connected between the inner housing 210 of the replacement cartridge and the guide plate 211.

[0056] Please refer to Figure 5 - Figure 6, in some embodiments, the wire 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 disposed inside the suture support tube 222 and fixedly connected to the suture support tube 222, and the first anchor member 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 inner shell 210 of the replacement chamber, and is slidably connected to the guide plate 211 and the inner shell 210 of the replacement chamber.

[0057] Further, the suture slider 223 is connected to the wire drive member 120. Specifically, one side of the suture slider 223 opposite to the wire drive member 120 has a first tab 224, and a first slot 121 corresponding to the first tab 224 is provided on the wire drive member 120. The first tab 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 tab 224 is inserted into the first slot 121. In this embodiment, the wire assembly 220 is connected in cooperation with the suture slider 223 and the wire drive member 120, realizing the linkage between the wire assembly 220 and the wire drive member 120.

[0058] Please refer to Figure 5 - Figure 7 , in some embodiments, the delivery device 1 includes a needle drive member 130 and a needle assembly 230; in this embodiment, the needle drive member 130 is disposed inside the handle 100, and the needle assembly 230 is disposed inside the replacement chamber 200; the needle drive member 130 is slidably connected to the intermediate plate member 111; the needle drive member 130 is connected to the needle assembly 230, and the needle drive member 130 is configured to drive the needle assembly 230 to perform a linear reciprocating motion; specifically, the needle assembly 230 includes a needle rod 231, a delivery needle 232 is connected to the distal end of the needle rod 231, and a needle slider 233 is connected to the proximal end of the needle rod 231; further, one side of the needle slider 233 opposite to the needle drive member 130 has a second tab 234, and correspondingly, a second slot 131 is provided on the needle drive member 130 corresponding to the second tab 234. The second tab 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 tab 234 is inserted into the second slot 131. The needle slider 233 is disposed between the guide plate 211 and the inner shell 210 of the replacement chamber, and is slidably connected to the guide plate 211 and the inner shell 210 of the replacement chamber.

[0059] It should be noted that before the prostate suspension device is activated, the first anchor member 261 and the suture portion 263 are engaged with each other and received within the needle assembly 230, and the second anchor member 262 is disposed within the access rod 212. After the first anchor member 261 and the suture portion 263 have been placed within the prostate tissue, the second anchor member 262 is firmly engaged with the suture portion 263 to form the fully assembled anchor assembly 260.

[0060] Please still refer to Figure 5 , in some embodiments, the replacement cartridge 200 further includes a push rod assembly 240 and a suture cutting assembly 250. The push rod assembly 240 is configured to push the second anchor member 262 distally along the access rod 212 and ultimately connect to the suture 221, and to disengage the second anchor member 262 from the access rod 212 and into the prostatic urethra. The suture cutting assembly 250 is configured to cut the suture 221 after the second anchor member 262 has been deployed.

[0061] Please refer to Figure 8 , in the present example, the needle driver 130 is connected to the wire driver 120 by a constant force spring 132, and the constant force spring 132 is configured to maintain a constant tension of the suture 221. Specifically, after the anchor assembly 260 is implanted into the prostate tissue, the tension of the suture portion 263 between the first anchor member 261 and the second anchor member 262 will vary with the size and firmness of the prostate, thereby resulting in differences in the lifting effect of the anchor assembly 260 on the prostate. In this embodiment, by providing the constant force spring 132, before the suture 221 is cut, the force of the constant force spring 132 within the handle 100 acts on the suture 221 through an intermediate member, ensuring that the tension of the suture portion 263 remains consistent after cutting.

[0062] Please still refer to Figure 8 , in some embodiments, the indicating member 140 includes a connecting portion 141 and an indicating portion 142; the indicating member 140 is fixedly connected to the wire driver 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 member 111.

[0063] Please refer to Figure 9 - Figure 10, in some embodiments, the conveying device 1 includes a housing. The intermediate plate 111 is disposed inside the housing. The intermediate plate 111 and the housing cooperate to form a guiding groove 144. A sliding portion 143 that is slidably connected with the guiding groove 144 is provided at the lower end of the indicating portion 142. Specifically, the housing includes the left housing 110 and the right housing 112. The intermediate plate 111 and the right housing 112 cooperate to form the guiding groove 144. In this embodiment, through the cooperation between the sliding portion 143 and the guiding groove 144, the stability of the movement of the indicating component 140 is improved.

[0064] The wire driving member 120 is located between the left housing 110 and the intermediate plate 111. In order to make the indicating portion 142 of the indicating component 140 located on the central axis of the handle 100, an elbow arm is formed between the connecting portion 141 and the indicating portion 142 of the indicating component 140. The elbow arm is in an "L" shape. The design of the elbow arm makes the indicating portion 142 exactly located on the central axis of the handle 100, increasing the overall aesthetic appearance of the conveying device 1.

[0065] Please refer to Figure 8 - Figure 9 , in some embodiments, a transparent protective shell 150 is further provided on the conveying device 1. The transparent protective shell 150 covers the outside of the indicating portion 142 for protecting the indicating component 140. Further, the transparent protective shell 150 is fixedly installed on the top of the housing. The movement of the indicating portion 142 can be clearly observed through the transparent shell.

[0066] Please refer to Figure 11 , in some embodiments, an indicative mark is provided on the transparent protective shell 150 for cooperating with the indicating component 140 to assist in judging the fixing condition of the first anchor member 261. Further, the indicative mark includes a first mark 152 and a second mark 153. The first mark 152 is located on one side of the transparent protective shell 150 close to the proximal end of the intervening rod 212, and the second mark 153 is located on one side of the transparent protective shell 150 close to the distal end of the intervening rod 212.

[0067] In some embodiments, a scale ruler (not shown in the drawings) is provided on the conveying device 1. The scale ruler is disposed on one side of the indicating component 140 for cooperating with the indicating component 140 to assist in judging the fixing condition of the first anchor member 261. In this embodiment, the scale ruler is disposed on the top of the transparent protective shell 150 and is located between the first mark 152 and the second mark 153.

[0068] In other embodiments, the scale ruler is disposed on the left housing 110 or the right housing 112.

[0069] Before the replacement cartridge 200 is installed on the handle 100 and before it is activated, the indicating portion 142 is located at the position of the first mark 152.

[0070] The anchor assembly 260 is deployed through a series of steps. The needle assembly 230 slides distally along the access rod 212 driven by the needle driver 130. The delivery needle 232 extends from the outlet at the distal end of the access rod 212 to the fully extended position, such that at least a portion of the delivery needle 232 penetrates the patient's prostatic capsule. The distal ends of the first anchor member 261 and the suture 221 are contained within the delivery needle 232 and move together with the delivery needle 232 to penetrate the prostatic tissue. During this process, the indicating portion 142 of the indicating member 140 moves from the first mark 152 to the second mark 153.

[0071] Next, when the distal ends of the first anchor member 261 and the suture 221 are held in place outside the prostatic capsule, the needle assembly 230 moves proximally along the access rod 212, causing the delivery needle 232 to move to the partially retracted position, i.e., the delivery needle 232 moves proximally relative to its fully extended position but has not yet been fully retracted into the access rod 212. The wire support tube helps to maintain the distal positions of the first anchor member 261 and the suture 221 while the needle assembly 230 moves proximally along the access rod 212. Accordingly, the distal ends of the first anchor member 261 and the suture 221 are held near the surface of the prostatic tissue and are no longer within the delivery needle 232. Thus, during this process, the indicating member 140 remains stationary. That is, the indicating portion 142 still remains at the second mark 153.

[0072] In the next step, the needle assembly 230 further moves proximally to retract into the access rod 212, while the wire assembly 220 also moves proximally. The first anchor member 261 is pulled against the tissue surface, which causes the first anchor member 261 to rotate about its connection with the suture 221 such that the first anchor member 261 is now transverse to the distal end of the suture 221. During this process, as the wire assembly 220 moves proximally, the indicating member 140 moves synchronously in the direction closer to the first mark 152. When the tension of the suture 221 reaches the calibrated value of the constant force spring 132, the wire assembly 220 stops moving, and at this time the indicating member 140 stops moving synchronously. The doctor can judge whether the deployment of the first anchor member 261 is in place based on the position where the indicating member 140 stops moving, combined with clinical experience, and further can judge whether the expected therapeutic effect can be achieved in this operation.

[0073] In the next step, the push rod assembly 240 within the handle 100 will act to couple the second anchor member 262 to the suture 221, which action defines the suture portion 263, which suture portion 263 becomes part of the final anchor assembly 260 implanted in the patient. At this time, the anchor assembly 260 is now completely separated from the cassette and handle 100 system

[0074] Please refer to Figure 4 、 Figure 12 、 Figure 13 、 Figure 14 , it should be noted that a driving mechanism for driving a series of actions in the replacement cartridge 200 is provided in the handle 100. 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 driving member 120 and the needle driving member 130) to promote the movement of various components (such as the needle assembly 230, the wire assembly 220, the push rod assembly 240 and the cutting assembly) in the replacement cartridge 200.

[0075] Please refer to Figure 15 , the replacement cartridge further includes a replacement cartridge housing 213 and an unlocking switch 270. The replacement cartridge housing 213 is connected to the guide plate 211 and the replacement cartridge inner housing 210 to form a replacement cartridge main body. The unlocking switch 270 is connected to the replacement cartridge housing 213. The unlocking switch 270 includes a knob 271. An operating handle 272 for convenient operation is provided on the knob 271. Concave structures 273 are symmetrically arranged on both sides of the operating handle 272. The concave structures 273 facilitate removing the replacement cartridge from the handle after unlocking.

[0076] In summary, a prostate suspension instrument proposed by the present invention sets an indicating member 140 on the handle 100 and makes the indicating member 140 linked through a plurality of intermediate members, so that a clinician can judge the fixation condition of the first anchor member 261 on one side of the prostate capsule by observing the movement of the indicating member 140. Therefore, the present invention effectively overcomes the defects in the prior art and has high industrial utilization value.
