Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an intelligent monitoring device for navigation in anterior mediastinal surgery. Background Technology

[0002] In modern medicine, especially in complex procedures like anterior mediastinal surgery, the use of endoscopic technology is crucial. With real-time endoscopic guidance, cutting devices can precisely remove tumors under image guidance. Compared to traditional open-chest surgery, the combined use of endoscopy and minimally invasive instruments reduces trauma, accelerates recovery, and achieves similar results for tumors ≤8cm in size compared to traditional surgery.

[0003] Traditional endoscopic equipment is mainly used for observation and diagnosis. However, with technological advancements and the increasing demand for minimally invasive surgery, the need for more efficient, precise, and safe surgical navigation tools is becoming increasingly urgent. Although existing endoscopic technology has made significant progress, some challenges remain in practical applications, such as how to prevent the camera from being contaminated by blood or tissue fluid while ensuring image clarity, and how to achieve real-time cleaning of the camera surface to ensure high-quality image transmission.

[0004] For example, a thoracoscope with automatic cleaning function, as described in Chinese patent application number CN202010561425.5, uses a hollow shaft motor to drive a brush rod, which in turn causes the bristles on the brush rod to repeatedly wipe the surface of the end cap, thereby achieving a cleaning effect.

[0005] However, some shortcomings still exist in actual use: First, when the camera is inserted into the patient's body through an incision, because the incision is usually small, the camera port will be contaminated with blood and tissue at the incision site as it is inserted, which will seriously affect the clarity of the subsequent images. Secondly, its brush handle will always cover part of the end cap surface, thus blocking the camera and creating a blind spot in the image during the operation. This blind spot will reduce the doctor's field of vision. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent monitoring device for anterior mediastinal surgery navigation, which can achieve integrated lens self-cleaning, anti-obstruction, and drainage to ensure a continuously clear intraoperative field of vision.

[0007] The specific technical solution adopted by this invention is as follows: An intelligent monitoring device for navigation in anterior mediastinal surgery includes an endoscope body and a tube disposed on the endoscope body, and further includes: An imaging unit, comprising an imaging component disposed at the end of a lens tube for acquiring images and a protective cover assembly disposed at the end of the imaging component; A drive unit, disposed inside the imaging assembly, is used to provide rotational power to the protective shield assembly; A contact unit, which is also disposed inside the imaging component; The protective cover assembly includes a shell assembly, which is rotatably connected to the end of the imaging assembly. The shell assembly is provided with an opening and closing part, an elastic scraping element is provided on the opening and closing part, and a liquid pushing part is also provided on the shell assembly. When the drive unit is started, it drives the protective cover assembly to rotate, so that the elastic scraping element scrapes and cleans the end imaging interface of the imaging assembly. Meanwhile, as the protective cover assembly rotates, the liquid-pushing part reciprocates under the action of the resisting unit, discharging the body fluid scraped off during the cleaning process out of the shell assembly along a preset path.

[0008] In a preferred embodiment, the imaging assembly includes a housing fixedly connected to the end of the lens tube, a mounting bracket fixedly connected to the inner wall of the housing, a camera fixedly mounted on the mounting bracket, and illumination lamps arranged in a ring at the end of the housing.

[0009] In a preferred embodiment, the shell assembly includes a protective shell, which is rotatably connected to the end of the outer shell. An annular isolation seat is fixedly connected to the inner wall of the protective shell, and drainage grooves are provided in annular distribution on the side of the protective shell.

[0010] In a preferred embodiment, the outer ring of the protective shell is provided with an annular slider, the inner ring of the shell is provided with an annular groove, and the annular slider is slidably connected in the annular groove.

[0011] In a preferred embodiment, the opening and closing part includes a sliding groove, and a plurality of the sliding grooves are arranged in a ring on the inner side of the protective shell. A protective flap is slidably connected in the sliding groove, and an elastic scraping element is fixedly connected to the side of the protective flap. A spring is fixedly connected to the inner wall of the sliding groove, and the other end of the spring is fixedly connected to the protective flap. An electromagnet for controlling the opening and closing of the protective flap is fixedly embedded in the inner wall of the protective shell.

[0012] In a preferred embodiment, the liquid-pushing part includes guide rods, and a plurality of guide rods are slidably inserted into an annular isolation seat in a ring-shaped distribution. One end of each guide rod is fixedly connected to an annular push plate, and a fixing ring is fixedly connected to the outer wall of one end of each guide rod. A compression spring is fixedly connected to one side of the fixing ring, and the other end of the compression spring is fixedly connected to the annular isolation seat.

[0013] In a preferred embodiment, the annular isolation seat is provided with a receiving groove, and the annular push plate is placed in the receiving groove.

[0014] In a preferred embodiment, a ball bearing is provided at one end of the guide rod near the contact unit.

[0015] In a preferred embodiment, the abutting unit includes a ring disposed inside the housing. The outer ring of the ring is fixedly connected to a support rod in a ring-shaped arrangement, and the other end of the support rod is fixedly connected to the inner wall of the housing. The side of the ring is connected to protrusions in a ring-shaped arrangement.

[0016] In a preferred embodiment, the drive unit is a hollow shaft motor, and its output shaft is fixedly connected to the protective shell.

[0017] The technical effects achieved by this invention are as follows: This invention achieves dynamic self-cleaning of the lens surface by incorporating a rotatable protective cover assembly and an elastic scraping element, effectively solving the problem of intraoperative visual field contamination. During insertion into the patient's body or surgery, blood and tissue fluid easily adhere to the imaging interface, causing image blurring. Driven by a driving unit, the protective cover assembly rotates, allowing the elastic scraping element to scrape the camera end face 360°, removing contaminants. This avoids surgical interruptions caused by incomplete cleaning or the need for repeated removal and cleaning with traditional equipment, significantly improving surgical continuity and safety. This invention features an openable protective flap structure, combining an electromagnet and a spring to achieve controllable opening and closing. During insertion, the protective flap closes to form a seal, preventing blood and tissue from the incision site from directly contaminating the lens. After cleaning, the electromagnet is energized to open the protective flap, restoring the imaging field of view. This design ensures lens cleanliness during insertion and avoids the field of view obstruction caused by a fixed brush, greatly expanding the surgeon's field of view. This invention achieves automatic discharge of cleaning waste liquid through the synergistic action of the liquid-pushing part and the contact unit. During the rotation of the protective cover, the protruding block periodically pushes the guide rod, causing the annular push plate to reciprocate, forcibly discharging the scraped body fluid through the drainage trough. Combined with the liquid collection chamber formed by the annular isolation seat and centrifugal force, this effectively prevents waste liquid backflow or accumulation that could cause secondary pollution, ensuring a continuously clean imaging environment and further improving image quality stability and equipment reliability.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0023] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0024] Please see the appendix Figures 1 to 5 As shown, this embodiment provides an intelligent monitoring device for anterior mediastinal surgery navigation, including an endoscope body 1 and a scope tube 2 disposed on the endoscope body 1, and further including: Imaging unit 3 includes an imaging component 31 disposed at the end of the lens tube 2 for acquiring images and a protective cover component 32 disposed at the end of the imaging component 31. Drive unit 4 is disposed inside imaging assembly 31 and is used to provide rotational power for protective cover assembly 32. The contact unit 5 is also disposed inside the imaging component 31; The protective cover assembly 32 includes a shell assembly 33, which is rotatably connected to the end of the imaging assembly 31. The shell assembly 33 is provided with an opening and closing part 34, an elastic scraping element 35, and a liquid pushing part 36. When the drive unit 4 is started, it drives the protective cover assembly 32 to rotate, so that the elastic scraping element 35 scrapes and cleans the end imaging interface of the imaging assembly 31. Meanwhile, as the protective cover assembly 32 rotates, the liquid pushing part 36 reciprocates under the action of the contact unit 5, discharging the body fluid scraped off during the cleaning process out of the shell assembly 33 along a preset path.

[0025] In this embodiment, the intelligent monitoring device for anterior mediastinal surgery navigation first acquires real-time images of the anatomical structure of the mediastinal region through the imaging component 31 of the imaging unit 3, providing visual guidance for surgical navigation. When the lens becomes blurry due to residual body fluid or tissue, the drive unit 4 is activated, causing the shell assembly 33 of the protective cover assembly 32 to rotate relative to the end of the imaging component 31. At this time, the elastic scraping element 35 fixed to the opening and closing part 34 rotates with the shell assembly 33, scraping the imaging interface at the end of the imaging component 31 to remove the attached substances. Simultaneously, during the rotation of the protective cover assembly 32, the liquid pushing part 36 is periodically contacted by the contact unit 5 inside the imaging component 31, generating a reciprocating motion: when the liquid pushing part 36 contacts the protruding structure of the contact unit 5, it is pushed and its elastic element is compressed; when it leaves the contact, it resets under the action of elastic restoring force. This reciprocating motion can push the scraped body fluid out of the device along a preset path, realizing the simultaneous cleaning and drainage.

[0026] The elastic scraping element 35, driven by the drive unit 4, actively removes contaminants from the lens, avoiding the need for repeated manual cleaning of the endoscope during surgery due to blurred vision, thus reducing surgical interruption time. This is especially suitable for areas with complex anatomical structures and prone to bleeding, such as the mediastinum. The synergistic action of the fluid pushing part 36 and the contact unit 5 enables the immediate drainage of scraped body fluid, effectively preventing fluid accumulation and secondary contamination of the lens, and ensuring image clarity.

[0027] The endoscope body 1 mainly consists of a handle and a control assembly. The handle provides a comfortable grip for precise operation. The control assembly includes various buttons and knobs, allowing the operator to flexibly control various functions of the endoscope, such as adjusting the light source brightness and switching between different observation modes. The endoscope tube 2 is designed with components that drive its bending. Through the coordinated work of these components, the endoscope tube 2 can flexibly bend and turn, allowing it to reach various corners of the human body for examination. The operator issues commands through the control assembly, which are transmitted to the bending components on the endoscope tube 2, thereby driving the endoscope tube 2 to perform corresponding bending movements. This design allows the imaging unit 3 to move flexibly in complex internal environments to adapt to different imaging needs. It should be noted that these specific structures are not shown in the figure; they are common and widely accepted designs in the prior art. These structures and working principles should be clear and easy to understand for those skilled in the art. Therefore, these details will not be elaborated upon further here.

[0028] The endoscope body 1 connects to an external display screen (using an interface or wireless transmission). The endoscope tube 2 and imaging unit 3 are inserted into the patient's chest cavity through an incision in the body. The images within the chest cavity are magnified and transmitted in real time to a screen in the operating room, providing the surgeon with a clear surgical field of view. This allows the surgeon to accurately determine the location and depth of tissue structures, thereby improving the precision and safety of the surgery. This not only increases the success rate of the surgery but also significantly reduces the operation time and the patient's recovery time, making surgical procedures more efficient and precise.

[0029] Secondly, please refer to again Figure 4 , Figure 7 , Figure 8 and Figure 9 The imaging component 31 includes a housing 311, which is fixedly connected to the end of the lens tube 2. A mounting bracket 312 is fixedly connected to the inner wall of the housing 311. A camera 313 is fixedly mounted on the mounting bracket 312. Illumination lamps 314 are arranged in a ring at the end of the housing 311.

[0030] In this embodiment, when the imaging component 31 is in operation, light is first emitted by the ring-shaped illumination lamps 314 at the ends of the housing 311 to illuminate the field of vision of the anterior mediastinal surgical area, ensuring sufficient and uniform illumination even in environments with complex internal anatomy or insufficient light. Image information of the thoracic cavity can be acquired in real time via the camera 313 mounted on the device. To ensure image clarity and accuracy, the ring-shaped illumination lamps 314 provide excellent lighting conditions. Furthermore, the illumination lamps 314 employ medical cold light source technology, which not only provides sufficient brightness but also effectively reduces heat generation, avoiding unnecessary heat injury to the patient.

[0031] Secondly, please refer to the following as well. Figures 5 to 9 The housing assembly 33 includes a protective housing 331, which is rotatably connected to the end of the outer housing 311. An annular isolation seat 332 is fixedly connected to the inner wall of the protective housing 331. Drainage grooves 333 are distributed in annular pattern on the side of the protective housing 331. The drive unit 4 is a hollow shaft motor, whose output shaft is fixedly connected to the protective housing 331. (The hollow shaft motor includes at least a housing, a stator, a hollow shaft rotor, and multiple sealing elements. Specifically, the hollow shaft motor adopts a product that is currently available on the market. When selecting a model, it should be selected as much as possible to meet the requirements of this application, provided that the specifications and usage scenarios are suitable. The specific model specifications are not limited here.)

[0032] In this embodiment, the protective shell 331 rotates relative to the end of the outer shell 311 of the imaging assembly 31 under the drive of the drive unit 4, causing the elastic scraping element 35 fixed to the opening and closing part 34 to scrape and clean the imaging interface of the camera 313. The bodily fluid generated by scraping is collected inward by the rotating protective shell 331 into the area of ​​the annular isolation seat 332.

[0033] Secondly, please refer to again Figure 7 The outer ring of the protective shell 331 is provided with an annular slider, and the inner ring of the outer shell 311 is provided with an annular groove, and the annular slider is slidably connected in the annular groove.

[0034] In this embodiment, when the drive unit 4 is activated and outputs rotational power, the protective shell 331 of the protective cover assembly 32 begins to rotate relative to the outer shell 311 of the imaging assembly 31. At this time, the annular slider located on the outer ring of the protective shell 331 slides circumferentially within the corresponding annular groove on the inner ring of the outer shell 311. This sliding connection converts the rotational motion transmitted by the drive unit 4 into a stable and smooth single axial rotation of the protective shell 331, thereby driving the elastic scraping element 35 fixed thereon to perform a scraping cleaning task on the imaging interface. Throughout the process, the annular slider is always constrained within the annular groove, ensuring the reliability of power transmission and effectively preventing the protective shell 331 from axially shifting or radially falling off during rotation, thus ensuring the accuracy and stability of the cleaning action.

[0035] Please refer to it again. Figure 5 , Figure 6 and Figure 8 The opening and closing part 34 includes a sliding groove 341. Multiple sliding grooves 341 are arranged in a ring on the inner side of the protective shell 331. A protective flap 342 is slidably connected in the sliding groove 341, and an elastic scraping element 35 is fixedly connected to the side of the protective flap 342. A spring 343 is fixedly connected to the inner wall of the sliding groove 341, and the other end of the spring 343 is fixedly connected to the protective flap 342. An electromagnet 344 for controlling the opening and closing of the protective flap 342 is fixedly embedded in the inner wall of the protective shell 331.

[0036] In this embodiment, when the opening / closing part 34 is in operation, the opening and closing state of the protective flaps 342 is controlled by the energization and de-energization of the electromagnet 344. In the initial state, the multiple protective flaps 342 are closed together, sealing the opening of the protective shell 331. When not in use, this prevents external dust from entering the interior of the shell 311; during insertion into the human body, it also avoids the problem of blurred vision caused by the camera 313 coming into contact with blood and tissue fluid.

[0037] Furthermore, it should be noted that a portion of the protective flap 342 and the elastic scraping element 35 are made of transparent material, while the non-transparent portion of the protective flap 342 is made of iron. This ensures that the camera 313 can capture images normally during insertion into the human body. When cleaning is required, the drive unit 4 is activated, causing the protective shell 331 to rotate. The elastic scraping element 35 rotates accordingly and scrapes and cleans the imaging interface. After cleaning, the electromagnet 344 is energized to generate magnetic force, attracting the protective flap 342 to slide along the sliding groove 341, compressing the spring 343, and causing the multiple protective flaps 342 to move away from each other, thereby opening the field of view and allowing the camera 313 to directly capture images. When the electromagnet 344 is de-energized, the magnetic force disappears, the compressed spring 343 releases its elastic force, and pushes the protective flap 342 to slide back along the sliding groove 341 to restore the protective state.

[0038] Please refer to it again. Figure 5 , Figure 7 and Figure 9 The liquid pushing part 36 includes guide rods 361. Multiple guide rods 361 are slidably inserted into the annular isolation seat 332 in a ring-shaped distribution. One end of the guide rod 361 is fixedly connected to an annular push plate 362. A fixing ring 363 is fixedly connected to the outer wall of one end of the guide rod 361. A compression spring 364 is fixedly connected to one side of the fixing ring 363, and the other end of the compression spring 364 is fixedly connected to the annular isolation seat 332. The annular isolation seat 332 is provided with a receiving groove, and the annular push plate 362 is placed in the receiving groove. A ball is provided at the end of the guide rod 361 near the contact unit 5.

[0039] The liquid-pushing part 36 generates axial reciprocating motion under the periodic action of the contact unit 5: when the ball at the end of the guide rod 361 contacts the protrusion 53 of the contact unit 5, the annular push plate 362 is pressed and moves, compressing the compression spring 364; when the contact is disengaged, the compression spring 364 rebounds and pushes the annular push plate 362 back to its original position. This reciprocating motion continuously discharges the body fluid accumulated at the annular isolation seat 332 to the outside of the equipment through the drainage channels 333, which are distributed in a ring on the side of the protective shell 331, along a preset path.

[0040] The integrated design of the protective shell 331, the annular isolation seat 332, and the drainage trough 333 enables efficient and directional discharge of cleaning waste liquid. The annular isolation seat 332 forms an independent liquid collection chamber inside the protective shell 331, effectively preventing the spread of body fluid after scraping and contamination of the imaging field of view; the annularly distributed drainage trough 333 accelerates the discharge of body fluid through the dual action of centrifugal force and thrust, significantly reducing the risk of liquid residue.

[0041] Please refer to it again. Figure 7 and Figure 10 The contact unit 5 includes a ring 51, which is disposed inside the housing 311. The outer ring of the ring 51 is fixedly connected to a support rod 52 in a ring-shaped arrangement, and the other end of the support rod 52 is fixedly connected to the inner wall of the housing 311. The side of the ring 51 is connected to protrusions 53 in a ring-shaped arrangement.

[0042] In this embodiment, when the protective cover assembly 32 rotates under the drive of the drive unit 4, the ball bearing at the end of the guide rod 361 periodically contacts the protrusion 53 of the contact unit 5 fixed inside the imaging assembly 31. Upon contact, the protrusion 53 applies axial pressure to the guide rod 361, pushing it to slide along the annular isolation seat 332 towards the side closer to the drainage trough 333, and compressing the compression spring 364 sleeved on the guide rod 361. Simultaneously, it drives the annular push plate 362 fixed to one end of the guide rod 361 to extend from the receiving groove of the annular isolation seat 332, pushing the body fluid accumulated in the groove towards the drainage trough 333. When the protrusion 53 disengages from the ball bearing, the compressed spring 364 releases its elastic potential energy, pushing the fixing ring 363 and causing the guide rod 361 and the annular push plate 362 to reset. This cycle repeats continuously, pushing the body fluid scraped off during the cleaning process out of the equipment through the drainage trough 333.

[0043] The working principle of this invention is as follows: During the surgery, the imaging component 31 acquires real-time images of the anatomical structures within the thoracic cavity via the camera 313, and is illuminated by uniform cold light sources provided by the lighting lamps 314 distributed in a ring at the end of the outer shell 311 to ensure clear imaging. When the lens surface becomes blurred due to blood or tissue fluid contamination, the drive unit 4 is activated, causing the protective shell 331 of the protective cover assembly 32 to rotate around the end of the outer shell 311. The elastic scraping element 35 of the opening and closing part 34 on the protective shell dynamically scrapes and cleans the imaging interface of the camera 313. At the same time, during the rotation of the protective shell 331, the ball bearing at the end of the guide rod 361 of the liquid pushing part 36 periodically contacts the abutment unit 5 fixed inside the imaging component 31. The protrusion 53 on the upper part of the device generates axial reciprocating motion under its pressure, compressing and releasing the compression spring 364, thereby driving the annular push plate 362 to reciprocate within the receiving groove of the annular isolation seat 332, continuously discharging the scraped body fluid from the drainage groove 333 distributed annularly on the side wall of the protective shell 331 to the outside of the device, realizing integrated automatic cleaning of "scraping-collecting-draining"; in addition, the opening and closing of the protective valve 342 in the sliding groove 341 is controlled by the electromagnet 344, and the spring 343 is used to reset it. After cleaning, it is opened to restore the imaging field of view. The whole process does not require the removal of the endoscope, effectively ensuring the continuity and clarity of imaging in complex mediastinal area surgery, improving surgical safety and operational efficiency.

[0044] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
