Description

Technical Field

[0001] This utility model relates to the field of minimally invasive prostate treatment technology, and to a prostate steam ablation system, particularly a prostate steam ablation system that is easy for operators to use, has high operating efficiency, low cost, and is easy to install. Background Technology

[0002] As living and medical conditions continue to improve, people's pursuit of quality of life is also constantly increasing, and age-related diseases are becoming increasingly prominent. Among them, benign prostatic hyperplasia is one of the common diseases in elderly men, which seriously affects their quality of life.

[0003] Benign prostatic hyperplasia (BPH) is an age-related disease, and patients often have complications such as heart, lung, brain, hypertension, renal insufficiency, or diabetes, which places high demands on anesthesia and perioperative management.

[0004] BPH (benign prostatic hyperplasia) is usually diagnosed when a patient complains of troublesome difficulty urinating and seeks medication. The main symptoms of BPH are urinary frequency and urgency, as well as a significant decrease in urination flow rate during urination. BPH can also cause urine to remain in the bladder, which can lead to lower urinary tract infections (LUTIs). In many cases, LUTIs can then ascend to the kidneys and cause chronic pyelonephritis, eventually potentially leading to renal insufficiency. BPH can also cause sexual dysfunction associated with sleep disturbances or anxiety caused by severe difficulty urinating. Therefore, BPH can significantly alter the quality of life of men as they age.

[0005] In the early stages of BPH, medication can alleviate some symptoms. For example, alpha-blockers treat BPH by relaxing the smooth muscle tissue found in the prostate and bladder neck, which also allows urine to flow out of the bladder more easily. These drugs are proven effective before glandular elements cause extreme cell growth in the prostate.

[0006] However, advanced BPH can only be treated with surgery or minimally invasive thermal ablation devices. Various methods have been developed utilizing electrosurgery or mechanical tissue aspiration (removal) and thermal or cryoablation of the prostate tissue within the cyst. In many cases, these interventions provide only temporary relief, and these treatments typically result in significant pre- and post-operative discomfort and morbidity.

[0007] Current thermal steam therapy equipment uses pulsed energy to heat sterile distilled water to 103°C, which is then injected into the hyperplastic prostate tissue via a disposable prostate thermal steam therapy instrument. The thermal steam releases heat energy through convection diffusion in the intercellular spaces, raising the tissue temperature in the treatment area by approximately 70°C within 9 seconds, thereby causing cell membrane denaturation and cell death. The necrotic tissue is absorbed by the body, reducing the volume of the prostate tissue near the urethra and alleviating LUTS. In addition, the heat energy can cause the blood vessels in the treatment area to collapse, ensuring minimal bleeding during the procedure.

[0008] CN 221786581 U provides a system for prostate steam ablation, which adopts an integrated design, eliminating the need for a separate cystoscope. It features two cameras (a front-facing camera and a rear-facing camera) on the guide sheath. The rear-facing camera, aligned with the steam delivery needle tip, allows observation of the needle's firing and retraction, as well as the treatment site, facilitating surgical procedures. The guide sheath includes a dedicated saline inlet and outlet channel for easy irrigation and cleaning of the surgical field, preventing contamination. Integrating the steam delivery needle, the saline inlet channel, and the saline outlet channel within the guide sheath reduces the diameter of the guide sheath (down to 6mm), thus lessening the patient's surgical burden. However, it still has the following drawbacks: 1) Although the rear-mounted camera of the guide tube sheath aligned with the tip of the steam delivery needle can observe the firing and retraction of the delivery needle, dirt can easily block the camera during operation, which will affect the operator's operation; 2) The unreasonable design of the guide tube sheath end affects the drainage efficiency, and poor drainage will greatly affect the operator's operating efficiency and bring additional burden to the patient; 3) The integrated design of the guide tube sheath end is not only costly, but also brings considerable difficulty to the installation of the sensor; 4) The operator needs to record the rotation angle and the number of treatments, which to some extent increases the operator's burden.

[0009] Therefore, developing a prostate vapor ablation system that is easy for operators to use, has high operating efficiency, low cost, and is easy to install is of great practical significance. Utility Model Content

[0010] Due to the aforementioned defects in the existing technology, this utility model provides a prostate steam ablation system that is convenient for operators, has high operating efficiency, low cost, and is easy to install. It solves the defects of existing steam thermal ablation equipment, such as easy dirt accumulation of the camera, poor drainage, high cost, inconvenient sensor installation, and inconvenience for operators.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A prostate steam ablation system includes an outer cannula for insertion into a patient's body via the urethra, a handle connected to the outer cannula, a heating tube disposed in the handle and configured to generate condensable steam (for applying voltage and current to generate high temperature, and using a high-temperature pyrogen to heat sterile water to generate steam), a steam delivery needle communicating with the heating tube and slidably disposed within the outer cannula (for delivering steam to the lesion site, reciprocating within the delivery needle tube, advancing from the starting point inside the protective head to the lesion site, and retracting back to the starting position of the protective head; the front end of the steam delivery needle is machined with 3 rows of 4 steam outlets, totaling 12 (configurable as needed), and the steam outlets are laser-marked, with the markings transmitted to a display screen via a camera for doctors to observe whether the steam needle has reached the lesion site), and an electromagnetic coil attached to the steam delivery needle for driving the steam delivery needle (for generating the power source for the forward and backward movement of the steam delivery needle).

[0013] The outer tube houses a camera module cable conduit (for camera module cable routing and assembly), a flushing conduit (for delivering saline solution), a delivery needle conduit (for limiting the reciprocating motion path of the steam delivery needle), and an outlet conduit (for delivering the flushed saline solution to the patient's body). A module base is mounted on the outer tube away from the handle. The module base is equipped with a camera (for converting images of the lesion into electrical signals and transmitting them to the host for display on the screen) and an LED light (providing a light source for illumination inside the patient's body, facilitating camera imaging). The flushing and outlet conduits are connected to the module base, with the flushing conduit's outlet located above the camera and LED light. The camera and LED light are angled and aligned with the steam delivery needle tip. The steam delivery needle is slidably mounted inside the delivery needle conduit, with the tip located on the side of the camera away from the handle. The camera module cable passes through the camera module cable conduit and enters the handle.

[0014] The outer sleeve is fitted with a protective head at the end away from the handle. The protective head has a hollow section in the middle, which is connected to the module base and the delivery needle tube. The protective head has side drain ports on both sides that are connected to the hollow section. The protective head has a top opening at the top for the steam delivery needle to pass through and which is connected to the hollow section.

[0015] Compared with existing technologies, the prostate steam ablation system provided by this utility model has the following advantages:

[0016] (1) The sensor module is installed on the module base, which can effectively solve the problem of difficult assembly process of camera and LED light, and provides a new idea for camera module assembly process;

[0017] (2) The protective head is fitted onto the outer tube, and the protective head is used as the path for the steam delivery needle. The steam delivery needle is turned forward at a 90-degree angle to facilitate the puncture of the urethral wall by the steam delivery needle.

[0018] (3) The module base and the protective head are connected by a plug-in joint, which is convenient for installation. This not only facilitates the installation of the sensor, but also greatly facilitates the assembly, reduces the difficulty of product processing, and reduces equipment costs.

[0019] (4) The structure is optimized by optimizing the arrangement of the flushing sub-tube, camera and LED light. The camera can be flushed at the same time, which can overcome the problem of the camera getting dirty easily and make it convenient for operators to work.

[0020] (5) The protective head is reasonably designed, which greatly improves the drainage efficiency and can improve the operating efficiency of the operator.

[0021] As a preferred technical solution:

[0022] In the prostate vapor ablation system described above, the flushing sub-tube is arranged above the delivery needle sub-tube, and the camera module cable sub-tube and the liquid outlet sub-tube are arranged on both sides of the flushing sub-tube and located between the flushing sub-tube and the delivery needle tube.

[0023] In the prostate vapor ablation system described above, the flushing sub-tube is connected to the saline inlet tube (which delivers saline to the flushing sub-tube). The saline inlet tube extends from the rear of the handle and has a saline Luer connector at its free end for connecting to the saline insertion tube and providing saline for flushing.

[0024] The outlet tube is connected to the outlet tube, which extends from the bottom of the handle, providing a way to drain saline solution from the patient's body and prevent organ damage due to excessive saline solution.

[0025] In the prostate steam ablation system described above, the heating tube is connected to the steam delivery needle via a steam transmission tube, which delivers the steam generated by the heating tube to the steam delivery needle.

[0026] The other end of the heating tube is connected to the sterile water inlet tube, through which sterile water is delivered to the heating tube. The sterile water inlet tube extends from the bottom of the handle and its free end is fitted with a sterile water Luer connector for connecting a sterile water inlet tube, providing sterile water as a source for generating steam.

[0027] As described above, the prostate vapor ablation system has a rounded end on the protective head away from the outer sheath, which facilitates insertion of the urethral tube.

[0028] As described above, in a prostate vapor ablation system, the outer sheath is engraved with scale lines to facilitate observation of the insertion depth into the urethra;

[0029] LED lights are installed on both sides of the camera.

[0030] As described above, in a prostate vapor ablation system, the outer sheath is fixed to the handle by a rotating body and the outer sheath can rotate around the handle. By controlling the angle of the rotating body, the doctor can be effectively prevented from operating the handle to rotate, thus improving the flexibility and operability of the surgery.

[0031] The rotating body has a built-in angle sensor that can transmit the angle status of the steam delivery needle to the host in real time and display it on the screen. This makes it easy for doctors to observe and understand the procedure, and can also effectively record the number of treatments at each angle.

[0032] As described above, the prostate steam ablation system includes a handle housing with a manual top cover for emergency use. If the steam delivery needle cannot return to the starting point when the return button is pressed, the manual top cover can be manually opened to manually pull the steam delivery needle back to the starting point. At the same time, the manual top cover cannot be reassembled after being opened, effectively avoiding the reuse of the device.

[0033] The handle housing contains a retraction board PCBA, a relay board, and a control board PCBA.

[0034] The retraction board PCBA is equipped with a retraction switch button and is electrically connected to the electromagnetic coil. The handle housing is equipped with a retraction button that matches the retraction switch button (used to trigger the steam delivery needle retraction function and retract the steam delivery needle to the starting position).

[0035] The control board PCBA is equipped with a flushing switch button, a firing switch button, and a steam switch button. The control board PCBA is electrically connected to the pump, electromagnetic coil, and heating tube that control the supply of physiological saline. The handle housing is equipped with a flushing button that matches the flushing switch button (used to trigger the physiological saline flushing function, lubricate for easy insertion of the protective head, and flush dirt from the camera surface to improve the clarity of the surgical field), a firing button that matches the firing switch button (used to trigger the steam delivery needle advance function, sending the steam delivery needle from the starting point to the lesion point), and a steam button that matches the steam switch button (used to trigger heating to generate steam, used to provide pyrogens for thermal ablation treatment).

[0036] The relay board is electrically connected to the return board PCBA and the control board PCBA, and the relay board is also connected to the camera module cable. The relay board is used to relay image signals and control signals.

[0037] In the prostate vapor ablation system described above, a spring telescopic pin A is fitted onto the flushing button, and the spring telescopic pin A is used to provide a pressing return force for the flushing button;

[0038] The firing button is fitted with a spring telescopic pin B, which is used to provide a pressing return force to the firing button.

[0039] The steam button is fitted with a spring telescopic pin C, which provides a return force to the steam button when pressed.

[0040] In the prostate vapor ablation system described above, the control cable is electrically connected to the relay board, and the camera image signal and control switch signal are transmitted to the host through the control cable;

[0041] The control cable extends from the rear of the handle and has a control cable aviation plug at its free end for signal transmission.

[0042] The power cable provides power to the various components (electromagnetic coil, heating tube, camera, LED light) in the prostate steam ablation system;

[0043] The power cable extends from the bottom of the handle and has an aviation plug at its free end.

[0044] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0045] The above-mentioned utility model has the following advantages or beneficial effects:

[0046] (1) The prostate vapor ablation system of this utility model has a sensor module installed on the module base, which can effectively solve the problem of difficult assembly process of camera and LED light, and provides a new idea for camera module assembly process;

[0047] (2) The prostate steam ablation system of this utility model uses a protective head fitted on the outer tube and uses the protective head as the travel path of the steam delivery needle. The steam delivery needle is rotated 90 degrees to facilitate the puncture of the urethral wall by the steam delivery needle. At the same time, the arc-shaped head design makes it easy to insert the urethral tube.

[0048] (3) The prostate vapor ablation system of this utility model, with the module base and protective head working together, not only facilitates the installation of the sensor, but also greatly facilitates the assembly, reduces the difficulty of product processing, and reduces equipment costs;

[0049] (4) The prostate steam ablation system of this utility model has an optimized structure and optimized the arrangement of the flushing tube, camera and LED light. It can flush the camera while flushing, which can overcome the problem of the camera being easily dirty and facilitate the operation of the operator.

[0050] (5) The prostate steam ablation system of this utility model has a reasonable protective head design, which greatly improves the drainage efficiency, reduces the surgical burden on patients and improves the operating efficiency of operators, and has good application prospects.
