Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a multifunctional prostate surgery diagnostic and treatment device. Background Technology

[0002] Prostate diseases (such as benign prostatic hyperplasia and prostate cancer) are among the most common diseases in urology. Currently, transurethral minimally invasive surgery is the mainstream treatment for these diseases. The surgical instruments used can enter the prostate gland through the body's natural cavity (urethra), providing doctors with a clear intraurethral view. Existing devices used for prostate disease diagnosis and treatment are mostly highly specialized designs. Different surgical procedures or treatment goals require specialized instruments with completely different structures and functions. For example, there are electrosurgical endoscopes specifically designed for high-frequency electrosurgical cutting and hemostasis, laser endoscopes specifically designed to transmit high-power lasers to achieve tissue vaporization or removal, and tissue shredders specifically designed for mechanical resection and removal of hyperplastic tissue.

[0003] However, when faced with complex prostate surgeries requiring the combined application of multiple technologies (e.g., precise glandular enucleation using a laser endoscope followed by meticulous hemostasis using an electrocautery endoscope, or removal of the enucleated tissue using a tissue fragmentation endoscope), surgeons must completely disengage the device being used during the procedure and switch to a different set of specialized instruments. This forced interruption and switching not only severely impacts the continuity and smoothness of the surgery, leading to a significant increase in surgical time and raising the patient's anesthesia risks and postoperative infection rates, but also causes more severe mechanical damage to the delicate urethral mucosa due to the repeated insertion and removal of different devices, exacerbating postoperative pain and recovery burden. Furthermore, the frequent switching of different instruments requires surgeons to constantly readjust to the differences in perspective, tactile feedback, and instrument characteristics, undoubtedly increasing the difficulty and potential risks of the surgery. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a multifunctional prostate surgery diagnostic and treatment device, thereby solving the technical problems of process interruption caused by frequent instrument changes in traditional surgery, increased operation difficulty and low efficiency during diagnosis and treatment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a multifunctional prostate surgery diagnostic and treatment device, including an electronic endoscope and an enucleation module, a rotary cutting module, and a laser module that are interchangeably connected thereto. The electronic endoscope includes a front section assembly, a middle section assembly, and a rear section assembly connected sequentially from front to back. The enucleation module includes a first front end head assembly, which is detachably connected to the electronic endoscope via the first front end head assembly and the rear section assembly. An electrode can be inserted from the front section assembly, sequentially extending into the middle section assembly, the rear section assembly, and the first front end head assembly, and then extending out from the first front end head assembly. The rotary cutting module includes a working rod, which is inserted from the rear section assembly, sequentially extending into the middle section assembly and the front section assembly, and then extending out from the front section assembly. The working rod is axially movable within the electronic endoscope. The laser module includes a second front end head assembly, which is detachably connected to the electronic endoscope via the second front end head assembly and the rear section assembly. An optical fiber can be inserted from the second front end head assembly into the rear section assembly, sequentially extending into the middle section assembly and the front section assembly, and then extending out from the front section assembly.

[0009] Furthermore, the front-end assembly includes an instrument tube; the middle-end assembly includes a middle section and a straight water valve connected front and rear, with the instrument tube passing through the middle section and its tail end fixed to the middle section; the rear-end assembly includes an anti-backflow pressure nut and a sheath locking nut connected front and rear, with the anti-backflow pressure nut connected to the straight water valve, and the sheath locking nut capable of locking the first or second front-end head assembly, or inserting a working rod; the instrument tube, straight water valve, anti-backflow pressure nut, and sheath locking nut form a through working channel for the electrode, working rod, or optical fiber to pass through.

[0010] Furthermore, the downstream component also includes an anti-backflow sleeve. After the anti-backflow pressure nut is connected to the direct water valve, a cavity is formed inside that matches the shape of the anti-backflow sleeve to accommodate and fix the anti-backflow sleeve. The anti-backflow sleeve has a first through hole with a straight slit at the front end and a circular shape at the rear end.

[0011] Furthermore, the mid-section component also includes a water inlet valve, which is connected to the chamber of the direct water valve. When the water inlet valve is opened, the irrigation fluid enters the chamber of the direct water valve and flows out through the instrument tube to rinse and cool the affected area.

[0012] Furthermore, the front-end assembly also includes a front section, an inner sheath, a lens, and a lens protection tube. The front section is fitted outside the instrument tube and fixed to the middle section. The inner sheath is fitted outside the instrument tube and its tail end is fixed to the front section. The lens is housed inside the lens protection tube. The instrument tube has a D-shaped cross-section, and the inner sheath has an O-shaped cross-section. An arc-shaped cavity is formed between the inner sheath and the instrument tube. The lens protection tube is housed inside the arc-shaped cavity and fixed to the instrument tube. The electronic endoscope also includes an imaging assembly, which includes a connected imaging connector and a light guide. The imaging connector is welded to the middle section, and the light guide has a built-in cable. The cable is connected to the lens sequentially through the imaging connector, the middle section, the front section, the arc-shaped cavity, and the lens protection tube.

[0013] Furthermore, it also includes an outer sheath assembly, which includes a water outlet valve, an outer sheath, and an outer sheath quick connector. The outer sheath is sleeved outside the inner sheath, and the tail end of the outer sheath is fixed to the inner side of the front end of the outer sheath quick connector. The rear end of the outer sheath quick connector is connected to the front end. The water outlet valve is connected to the outer sheath quick connector and communicates with the inner cavity of the outer sheath. The annular gap between the outer sheath and the inner sheath forms a water outlet channel. The head end sidewall of the outer sheath has multiple second through holes. In use, the water outlet valve is connected to a negative pressure device to provide suction, which draws surgical waste from the front port of the outer sheath and the multiple second through holes into the water outlet channel and discharges it from the water outlet valve.

[0014] Furthermore, the outer sheath assembly also includes a sheath plugging flange, which is trumpet-shaped with an open end and a closed end. The sheath plugging flange is sleeved on the outside of the outer sheath, and the tail end is fixed to the outside of the front end of the outer sheath quick connector for positioning the multifunctional prostate surgery diagnostic and treatment device.

[0015] Furthermore, the removal module also includes a first slider assembly, which is located behind the first front end assembly. The first front end assembly includes a first front end, which is connected to the rear end of the sheath locking nut. The first slider assembly includes a removal hand slider. During installation, the electrode is inserted from the front end of the instrument tube and extends backward sequentially into the straight water valve, the anti-backflow pressure nut, the sheath locking nut, and the first front end. After the electrode extends out from the first front end, it is fixed inside the removal hand slider and energized. The removal hand slider carries the electrode and reciprocates relative to the first front end to control the extension and retraction of the electrode at the front end of the instrument tube.

[0016] Furthermore, the working rod of the rotary cutting module includes an inner rotary cutting rod and an outer rotary cutting rod. The inner rotary cutting rod is rotatably sleeved inside the outer rotary cutting rod. The front end of the inner rotary cutting rod is serrated, and the front end of the outer rotary cutting rod has an oblique hole, through which the front end of the inner rotary cutting rod protrudes. During operation, the working rod is inserted into the mirror sheath locking nut and then sequentially extends into the anti-backflow pressure nut, the straight water valve, and the instrument tube, extending out from the front end of the instrument tube. After being powered on, the inner rotary cutting rod rotates alternately in both forward and reverse directions.

[0017] Furthermore, the laser module also includes a second slider assembly, which is located behind the second front end assembly. The second front end assembly includes a second front end, which is connected to the rear end of the sheath locking nut. The second slider assembly includes an optical fiber channel and a laser hand slider. The optical fiber channel is fixed in the laser hand slider and extends forward sequentially into the second front end, sheath locking nut, anti-backflow pressure nut, straight water valve, and instrument tube until the end of the instrument tube. The optical fiber passes through the optical fiber channel. The laser hand slider moves back and forth relative to the second front end relative to the optical fiber channel to control the extension and retraction of the optical fiber channel at the end of the instrument tube.

[0018] (III) Beneficial Effects

[0019] The beneficial effects of this invention are:

[0020] This invention discloses a multifunctional prostate surgery diagnostic and treatment device. Because the electronic endoscope comprises a front section assembly, a middle section assembly, and a rear section assembly connected sequentially from front to back, when connected to an enucleation module, the rear section assembly can be detachably connected to the first front end head assembly of the enucleation module. Electrodes can be inserted from the front section assembly, sequentially extending into the middle section assembly, the rear section assembly, and the first front end head assembly, and then extending out from the first front end head assembly. When connected to a rotary cutting module, the working rod of the rotary cutting module can be inserted from the rear section assembly, sequentially extending into the middle section assembly and the front section assembly, and then extending out from the front section assembly. When connected to a laser module, the rear section assembly can be detachably connected to the second front end head assembly of the laser module. An optical fiber can be inserted from the second front end head assembly into the rear section assembly, sequentially extending into the middle section assembly and the front section assembly, and then extending out from the front section assembly.

[0021] Compared to existing technologies, this invention consists of a universal electronic endoscope and multiple replaceable functional end-effector modules (enucleation module, rotary cutting module, and laser module). It allows for the completion of various surgical procedures such as enucleation, rotary cutting, and laser vaporization / cutting simply by quickly replacing the enucleation, rotary cutting, and laser modules at the rear of the electronic endoscope, without requiring the replacement of the entire electronic endoscope. This significantly reduces the operational difficulty during diagnosis and treatment, achieving "one endoscope for multiple uses," integrating multiple functions, simplifying the operation process, improving surgical efficiency, reducing patient trauma, and promoting the development of minimally invasive urological surgery towards greater efficiency, precision, safety, and comfort.

[0067] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0068] like Figure 1-23 As shown, this invention provides a multifunctional prostate surgical diagnostic and treatment device, including an electronic endoscope 1 and an enucleation module 2, a rotary cutting module 3, and a laser module 4, which are interchangeably connected to it. The electronic endoscope 1 provides a field of view for the surgery, the enucleation module 2 performs enucleation operations during the surgery by connecting electrodes, the rotary cutting module 3 performs rotary cutting operations during the surgery, and the laser module 4 performs laser-related operations during the surgery by connecting optical fibers.

[0069] like Figure 1 , Figure 8 , Figure 15 As shown, the electronic endoscope 1 includes a front section assembly 11, a middle section assembly 12 and a rear section assembly 13 connected sequentially from front to back, as well as an imaging assembly 14 and an external sheath assembly 15.

[0070] like Figure 2 , Figure 4 , Figure 5-6 , Figure 9-10 , Figure 12-13 , Figure 16-17 , Figures 19-20 As shown, the front component 11 includes an instrument tube 111, a front section 112, an inner sheath 113, a lens 114, and a lens protection tube 115. The front section 112 is sleeved on the outside of the instrument tube 111, the inner sheath 113 is sleeved on the outside of the instrument tube 111 and its tail end is fixed in the front section 112, and the lens 114 is set in the lens protection tube 115 to provide a field of view for endoscopic surgery.

[0071] The cross-section of the instrument tube 111 is D-shaped, and the cross-section of the inner sheath tube 113 is O-shaped. An arc-shaped cavity is formed between the inner sheath tube 113 and the instrument tube 111. The lens protection tube 115 is disposed in the arc-shaped cavity and fixed to the instrument tube 111.

During operation, the direct water valve 122 is opened, allowing fluid and tools to pass smoothly. During idle operation, the direct water valve 122 is closed, cutting off the passage of fluid and tools. In this state, the direct water valve 122 acts as a check valve to prevent tools from accidentally entering and fluid from being drawn back. The inlet valve 123 is connected to the direct water valve 122 and communicates with its chamber. When the inlet valve 123 is opened, the irrigation fluid enters the chamber of the direct water valve 122 and flows out through the instrument tube 111 to rinse and cool the affected area.
