Description

Technical Field

[0001] This utility model relates to surgical instruments for benign prostatic hyperplasia, and more particularly to an integrated prostate implant delivery tube assembly. Background Technology

[0002] Existing prostate implant delivery systems typically require a delivery handle and delivery tubing to facilitate a step-by-step implantation process. The delivery tubing comprises a main tube, a puncture needle system, an anchoring wire cutting system, the implant, and an imaging system. The puncture needle system punctures the prostate capsule and releases the implant's capsule flap. The anchoring wire cutting system releases the urethral end flap on the prostatic urethral side and tightens and cuts the anchoring wire. Due to the limited diameter of the prostatic urethra, the main tube of the delivery tubing, acting as a support frame for the puncture needle system and anchoring wire cutting system, typically has thin walls, making it prone to deformation and instability during implantation. Furthermore, the main tube's structure, designed to withstand the loads of its internal components, often has numerous sharp angles, increasing the risk of urethral injury during passage through the urethra to the prostate. Therefore, a sheath structure is usually required to facilitate the implantation of the entire delivery tubing assembly. In this process, the main tube and sheath are connected in a movable manner, requiring a high level of technical skill and precise control. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings. Figures 1-11 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figures 9-11 The image shows a coronal sectional view of the lower abdomen of a man with benign prostatic hyperplasia (BPH). The bladder (01) is a vesicular structure used to store urine, located posterior to the pubic bone (02). Its opening connects to a soft, elastic tubular structure called the urethra (03), through which urine stored in the bladder is discharged from the tip of the penis. The prostate (04) is located peripherally in the urethra at the junction of the urethra (03) and bladder (01). The health of the prostate (04) significantly impacts the normal function of the male reproductive system. For example, prostatic hyperplasia can compress the urethra (03), narrowing the urethral passage and potentially leading to problems such as urinary frequency, urgency, dysuria, and sexual dysfunction. The prostatic capsule (05) is distributed on the outer wall of the prostate (04), possessing a certain structural strength.

[0027] The anchoring implant 9, as a medical device for minimally invasive surgery to treat benign prostatic hyperplasia (BPH), typically includes a capsule piece 18 that is positioned on the outer side of the prostatic capsule 05, a urethral end piece 17 that is attached to the inner wall of the prostatic urethra, and an anchoring line 19 connecting the capsule piece 18 and the urethral end piece 17. The anchoring line pulls the urethral end piece 17 closer to the capsule piece 18, thereby expanding the urethral stricture and clearing the urine passage. In existing technologies, the capsule piece 18 has a linear structure. After the capsule piece 18 is released on the outer side of the prostatic capsule 05, it unfolds to form a T-shape with the anchoring line 19. When the urethral end piece 17 is released on the urethral side and fixedly engaged with the anchoring line head, it forms an I-shape (e.g., ...). Figure 8 (As shown).

[0028] like Figures 1-5 As shown, this utility model discloses an integrated prostate implant delivery pipeline assembly. The delivery pipeline assembly 2 includes a main body 3, a puncture needle assembly 5, a tangential assembly 6, and an imaging system 8. The radial cross-section of the main body 3 is elliptical or circular. The main body 3 has a puncture needle shuttle lumen 31, a scope lumen 32, and a tangential shuttle lumen 33 respectively formed from top to bottom along its length. An inlet chamber 34 and an outlet chamber 35 are respectively provided on both sides of the scope lumen 32 within the main body 3. The main body 3 of this utility model is a casting with an elliptical cross-section, possessing high structural strength and stability. It not only allows for convenient placement of the puncture needle assembly 5, the tangential assembly 6, and the imaging system 8, but also has a smooth shape that allows direct passage through the urethra to the prostate surgical area, reducing surgical difficulty and improving surgical efficiency.

[0029] like Figure 4 As shown, a blade module 4 is connected to the front end of the main body 3. A puncture groove is provided on the side of the blade module 4 near the front end of the tangential shuttle cavity 33. An arc-shaped channel for the puncture needle to pass through is provided at the end of the blade module 4 near the puncture needle shuttle cavity 31, and the outlet end of the arc-shaped channel is correspondingly set with the puncture groove. Observation windows are provided on both sides of the blade module 4 corresponding to the endoscope cavity 32.

[0030] like Figures 5-6 As shown, the puncture needle assembly 5 includes a puncture needle shuttle tube 11 and a puncture needle pusher tube 12 slidably connected within the puncture needle shuttle tube 11. The front end of the puncture needle pusher tube 12 is supported at the rear end of the puncture needle 10. A capsule sheet 18 is housed within the puncture needle 10, and an anchoring line 19 is fixedly connected to the rear end of the capsule sheet 18. A capsule sheet pusher tube 13 is located within the puncture needle pusher tube 12 at the rear end of the capsule sheet 18, and the anchoring line 19 is housed within the capsule sheet pusher tube 13. The puncture needle 10 is accommodated within the arc-shaped channel of the blade module 4. Driven by the puncture needle pusher tube 12, the puncture needle 10 can pass through the arc-shaped channel from the puncture slot side, thus ensuring that the puncture needle 10 forms a certain angle with the main tube body 3 when released, facilitating puncture of the prostate hyperplasia site (e.g., ...). Figure 9(As shown). The puncture needle 10 contains a capsule sheet 18. During the puncture process, the capsule sheet 18 and the anchoring line 19 are simultaneously punctured into the prostate capsule 05. As the puncture needle push tube 12 retracts and pulls the puncture needle 10 back, the capsule sheet push tube 13 moves forward relative to the puncture needle push tube 12, thereby releasing the capsule sheet 18 on the outer wall of the prostate capsule 05 and automatically opening it. After the capsule sheet 18 opens, it forms a T-shaped structure with the anchoring line 19. Then, the capsule sheet push tube 13 moves backward, pulling the anchoring line 19 back to tighten the capsule sheet 18 on the outer wall of the prostate capsule 05 (as shown). Figure 10 (As shown).

[0031] like Figure 5 and Figure 7 As shown, the tangent assembly 6 includes a tangent shuttle tube 14, a tangent knife tube 15 housed inside the tangent shuttle tube 14, and a urethral end piece pusher 16 housed inside the tangent knife tube 15. A urethral end piece 17 is positioned at the front end of the urethral end piece pusher 16. The tangent shuttle tube 14, tangent knife tube 15, and urethral end piece pusher 16 all adopt a square structure. The front end of the tangent shuttle tube 14 is inserted into the blade module 4, and a urethral end piece through-hole is provided at the front end of the tangent shuttle tube 14 corresponding to the puncture groove. The front end of the tangent knife tube 15 has a tangent groove corresponding to the urethral end piece through-hole, and a tangent cutting edge is provided at the rear end of the tangent groove. The dimensions of the urethral end piece through-hole and the tangent groove are larger than the dimensions of the urethral end piece 17 to allow the urethral end piece 17 to pass through the urethral end piece through-hole and the tangent groove during anchoring. A V-shaped notch is provided at one end of the urethral end piece 17 for the anchoring line 19 to be inserted. After the capsule 18 is released and the anchoring line is tensioned, the urethral end piece pusher 16 pushes the urethral end piece 17 forward. During the forward movement of the urethral end piece 17, the anchoring line 19 is correspondingly engaged at the root of the V-shaped notch, thereby achieving anchoring of the anchoring line 19 and the urethral end piece 17. Then, the suturing knife tube 15 is pushed forward along the suturing shuttle tube 14. During the forward movement of the suturing knife tube 15, the cutting edge can cut the anchoring line 19, completing the release of the anchoring implant (e.g., ...). Figure 11 (As shown).

[0032] like Figure 3 As shown, the imaging system 8 includes a camera module and a wire housed in the endoscope cavity 32. One end of the wire is connected to the camera module, and the other end of the wire is provided with an external plug. The external plug is connected to the display and enters the prostate surgery scene through the display digital display delivery pipe assembly 2.

[0033] like Figure 2 and Figure 4As shown, the water inlet chamber 34 and the water outlet chamber 35 are respectively provided with water inlet and water outlet at the front end of the main body 3, and the water inlet chamber 34 and the water outlet chamber 35 are respectively provided with water inlet control valve and water outlet control valve at the rear end of the main body 3. The control valve 7 can be a miniature control valve to meet the needs of rinsing the surgical area and draining the accumulated fluid.

[0034] In the above embodiments, the capsule 18 can be made of metal or plastic, and the anchoring line 19 can be made of rigid or elastic material. Using an elastic material can better shorten the distance between the capsule 18 and the urethral end piece 17 through its elastic contraction. The urethral end piece 17 can be made of metal or plastic, so that the prostate lateral lobe can expand outward at the inner wall of the urethra, thereby expanding the urethral obstruction.

[0035] It should be noted that the conveying handle 1 adopts the "handle for an anchor conveying system" disclosed in Chinese patent CN108095778B to realize the driving function of the conveying pipeline assembly 2, which will not be elaborated here.

[0036] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
