Description

Technical Field

[0001] The present invention relates to endoscopic surgical instruments, and particularly to a visualization diagnosis and treatment system with a body cavity expansion device used in endoscopic surgery.

Background Art

[0002] With the development of endoscopic technology, there are a large number of examinations and surgeries that can be performed endoscopically, such as gastroscopy, enteroscopy, hysteroscopy, biopsy, abortion surgery, etc.

[0003] Conventionally, it is common to insert various mirrors such as laparoscopes, thoracoscopes, and hysteroscopes into the human body and perform examinations and surgeries under direct vision through a lens. In order to minimize the surgical wound, the surgical incision is usually made as small as possible. For this reason, the diameters of the related mirrors and surgical instruments are also relatively small.

[0004] However, since the tissues and organs in the human body are flexible, the body cavities of tissues and organs such as the uterus, stomach, and intestinal tract are usually closed without external force. As a result, after inserting a small-diameter endoscopic instrument into the body cavity, the tissue at the front end sinks, so especially in the case of body cavities such as the uterus and intestinal tract, the observation area at the front end of the endoscope becomes very small, and the clinical observation effect is often not good.

[0005] Therefore, it is necessary to further improve the conventional endoscopic diagnosis and treatment equipment in order to obtain a better clinical observation effect. In addition, in the prior art, the observation and treatment processes are often separated, and during clinical treatment, it is necessary to exchange and operate different instruments. Especially in the case of biopsy collection, laser resection, etc., it is very inconvenient. Therefore, it is necessary to further improve and integrate the functions of the conventional endoscopic diagnosis and treatment equipment.

Summary of the Invention

[0006] The visualization medical system with a body cavity expansion device of the present invention can expand the tip of the observation system by the expansion end of the expansion mechanism provided at the tip of the observation system, thereby achieving the objective of effectively expanding the field of view and resulting in excellent clinical observation results.

[0007] The features of the visualization medical system with a body cavity expansion device of the present invention are as follows. The visualization medical system 100 with a body cavity expansion device comprises a body cavity expansion mechanism 1, an observation mechanism 2, a circuit system 3, a power supply system 104, an operating mechanism 5, and a display system 102. A. The body cavity expansion mechanism 1 is provided with an expansion end 11, which is located at the tip 5-1 of the operating mechanism 5, and can expand the body cavity at the front end of the observation mechanism 2, thereby expanding the observation field of view of the observation mechanism 2. B. The observation mechanism 2 comprises an illumination module 21, a lens module 22, a signal processing module 23, and a case 24. Images and videos observed by the lens module 22 within the light field of the illumination module 21 are processed by the signal processing module 23, and then output to the display system 102 by the circuit system 3 for display. The illumination module 21, the lens module 22, and the circuit system 3 are connected and then sealed and mounted inside the case 24. C, the observation mechanism 2 and the display system 102 are connected to the power supply system 104 via the circuit system 3.

[0008] The visualization medical system with a body cavity expansion device of the present invention is provided with an expansion end 11 of the body cavity expansion mechanism 1 at the tip of the camera 22-1 of the observation mechanism 2. The expansion end 11 expands the body cavity at the front end of the observation mechanism 2, thereby expanding the observation field of view of the observation mechanism 2, and is particularly suitable for examination and treatment processes such as hysteroscopy and colonoscopy. When in use, the visualization medical system with a body cavity expansion device of the present invention is inserted into the body cavity, the expansion end 11 expands the body cavity, and the observation mechanism 2 observes the expanded area. The image and video signal observed by the lens module 22 are output to the display system 102 by the circuit system 3 and displayed. Because the body cavity at the front end of the observation mechanism 2 is expanded, the observation field of view of the lens module 22 becomes wider, and the clinical observation effect is enhanced.

[0009] The observation mechanism 2 and the body cavity expansion mechanism 1 may be provided separately or integrated together.

[0010] To reduce the cost of clinical use, the observation mechanism 2 and the body cavity expansion mechanism 1 may be provided separately. The body cavity expansion mechanism 1 is provided with a sheath tube 12, and the observation mechanism 2 is sealed. During clinical observation, the observation mechanism 2 is placed in the channel 12-3 of the sheath tube 12, and after observation is complete, the observation mechanism 2 is retrieved, disinfected, and sterilized before being reused. The body cavity expansion mechanism 1 is simply disposable, significantly reducing the cost of clinical use.

[0011] When the observation mechanism 2 and the body cavity expansion mechanism 1 are integrated, the sheath tube of the body cavity expansion mechanism 1 constitutes the case 24. The illumination module 21, the lens module 22, and the circuit system 3 of the observation mechanism 2 are sealed within the sheath tube 12.

[0012] The expansion end 11 is an expansion mesh 11-1. The camera 22-1 can directly observe the area behind the expansion mesh 11-1 through the mesh-like gaps, and observation of the entire procedure and the entire surgical area is possible even if the expansion mesh 11-1 is not made of a transparent material.

[0013] The camera 22-1 of the lens module 22 is provided at the rear end of the extended mesh 11-1, and the extended mesh 11-1 is within the field of view of the camera 22-1.

[0014] The technical solution of post-positioning the camera 22-1 ensures that the extended mesh 11-1 is entirely within the field of view of the camera 22-1, and since the observation angle of the camera 22-1 is angled forward of the surgical or examination area, there are no blind spots during the procedure described above. The technical solution of post-positioning the camera makes clinical examinations and procedures safer and more effective.

[0015] The camera 22-1 of the lens module 22 is provided inside the expanded mesh 11-1. By providing the camera 22-1 inside the expanded mesh 11-1 and adjusting the direction of the camera 22-1, or by providing a plurality of spatially distributed cameras 22-1, surrounding tissues and organs can be observed in three dimensions.

[0016] The observation direction of the camera 22-1 of the lens module 22 is adjustable. By adjusting the observation direction of the camera 22-1, the condition of the surrounding tissue can be observed comprehensively, resulting in a more complete observation for clinical use.

[0017] An adjustment mechanism 22-11 for adjusting the observation direction of the camera 22-1 is provided on the handle 52 of the operating mechanism 5. By providing the adjustment mechanism 22-11 on the handle 52, the observation direction of the camera 22-1 can be easily adjusted from outside the body during clinical use, making operation easier.

[0018] The operating direction of the expansion end 11 is adjustable. The operating direction of the expansion end 11 can be adjusted as needed, allowing for better adaptation to the structural shape of the surrounding body cavity, and the clinical effectiveness is particularly improved in areas that are difficult to clean or observe, such as the corners of the uterus.

[0019] A rocking mechanism 11-4 for adjusting the operating direction of the extended end 11 is provided on the handle 52. By providing the rocking mechanism 11-4 on the handle 52, the operating direction of the operating part of the curettage device 11 can be easily adjusted from outside the body during clinical use, making operation easier.

[0020] The observation direction of the camera 22-1 of the lens module 22 and the operating direction of the extension end 11 can be adjusted simultaneously. In actual application, a clinician can adjust either the observation direction of the camera 22-1 or the operating direction of the extension end 11 as needed, or they can adjust both the observation direction of the camera 22-1 and the operating direction of the extension end 11 simultaneously.

[0021] When simultaneously adjusting the observation direction of the camera 22-1 and the operating direction of the extension end 11, the adjustment mechanism 22-11 and the swing mechanism 11-4 can be combined into a single adjustment mechanism and provided on the handle 52.

[0022] The body cavity expansion mechanism 1 further comprises a sheath tube 12, the expansion mesh 11-1 being compressible within the sheath tube 12, and after the sheath tube 12 is removed rearward and the constraint is released, the expansion mesh 11 can be fully or substantially restored to its pre-compression shape. The sheath tube 12 comprises an inner sheath tube 12-1 and an outer sheath tube 12-2, the expansion mesh 11-1 being compressed within the outer sheath tube 12-2.

[0023] The expansion mesh 11-1 is compressible within the sheath tube 12, and after the sheath tube 12 is removed rearward and the constraint is released, the expansion mesh 11-1 can fully or substantially recover to its pre-compression shape. During clinical use, the expansion mesh 11-1 can be housed within the sheath tube 12, and after insertion into the body cavity, the sheath tube 12 is retracted to release the expansion mesh 11-1, causing it to unfold and expand the body cavity in front of or around the camera 22-1, thereby widening the field of view. During clinical use, the site of examination or surgery and surrounding tissues can be observed more clearly, and the observation effect in clinical use is excellent. The curettage wire 11-31 of the expansion mesh 11-1 may be made from various shapes of materials such as wire material, tubular material, or sheet material. The expansion mesh 11-1 can be made into various geometric shapes such as ellipsoidal or pear-shaped depending on the shape of the body cavity to better fit the shape of the body cavity, and is particularly suitable for corners within the body cavity where cleaning is difficult.

[0024] The aforementioned visualization medical system 100 with a body cavity expansion device further includes a negative pressure suction mechanism 4. The negative pressure suction mechanism 4 allows for the rapid aspiration and discharge of tissue fluid such as blood generated during examination or surgery, enabling clearer observation during clinical use.

[0025] The negative pressure suction mechanism 4 of the visualization medical system 100 with a body cavity expansion device comprises a suction inlet 41, a suction outlet 42, and a suction channel 43. The sheath tube 12 of the visualization medical system 100 with a body cavity expansion device is a double-lumen tube, in which the observation mechanism 2 may be provided, and the other lumen tube constitutes the suction channel 43 or is provided with the suction channel 43. The suction inlet 41 is provided at the tip of the sheath tube 12, and the suction outlet 42 of the negative pressure suction mechanism 4 is provided at the rear end of the sheath tube 12. The double-lumen channel design allows the circuit system 3 to be isolated from fluids such as blood and tissue fluid that may occur during surgery, more effectively avoiding safety hazards such as short circuits and electrical leakage during use, and making the clinical use process safer.

[0026] The negative pressure suction mechanism 4 is provided with a negative pressure control switch 44 capable of controlling the negative pressure state. The negative pressure control switch 44 can turn on / off the negative pressure suction mechanism 4, and can also adjust the negative pressure suction force of the negative pressure suction mechanism 4 according to the amount of tissue, blood, and tissue fluid peeled off in the uterus during the treatment process. During clinical use, a doctor can easily adjust to the desired negative pressure suction force, thereby avoiding the situation that the peeled tissue cannot be timely sucked and removed due to the negative pressure suction force being too small, or the situation that tissues such as the endometrium are accidentally damaged due to the negative pressure being too large.

[0027] The negative pressure control switch 44 is provided on the handle 52 of the operation mechanism 5. By providing the negative pressure control switch 44 on the handle 52, during clinical use, medical staff can operate it with one hand, making the use process more convenient.

[0028] The visualization diagnosis and treatment system 100 with the body cavity expansion device further includes a cleaning mechanism 6, and the water outlet 61 of at least one of the cleaning mechanisms 6 is at the tip of the camera 22-1 of the lens module 22. During the inspection and treatment process, the cleaning mechanism 6 can clean the camera 22-1 and timely remove the blood at the tip of the camera 22-1 by washing, ensuring that the observation field of view is kept clean. In addition, the cleaning mechanism 6 can also timely clean the inside of the body cavity, especially can timely clean the surgical site, thereby enabling the surgical or inspection site to be observed in a timely manner, ensuring the safety of the surgical or inspection process, and making the clinical treatment process safer.

[0029] The sheath tube 12 of the visualization diagnosis and treatment system 100 with the body cavity expansion device is a triple lumen tube. The observation mechanism 2 is provided in the first lumen tube. The second lumen tube constitutes the suction channel 43 or the suction channel 43 is provided therein. The third lumen tube constitutes the water supply path 63 of the cleaning mechanism 6 or is used for inserting and removing surgical instruments. The water inlet 62 of the cleaning mechanism 6 is provided at the rear end of the sheath tube 12. The design of the triple lumen channel ensures that the circuit system 3 is blocked and protected, and the cleaning channel and the suction channel can be separated. Thereby, it can be more effectively ensured that the aspirated tissue or liquid does not flow back into the uterus during cleaning, and the use process becomes more efficient and safe.

[0030] The cleaning mechanism 6 is provided with a flushing switch 64 for controlling the cleaning water. The flushing switch 64 can turn on / off the cleaning mechanism 6 and can also control the water volume and cleaning pressure of the cleaning water. During clinical use, the clinician can turn on or off the cleaning mechanism ⑥ according to the actual requirements of the operation process, and can select the appropriate water volume and pressure of the cleaning water as needed, making the clinical use process more convenient.

[0031] The flushing switch 64 is provided on the handle 52 of the operation mechanism 5. By providing the flushing switch 64 on the handle 52, during clinical use, medical staff can operate with one hand, making the use process more convenient.

[0032] The expansion mesh 11-1 of the body cavity expansion mechanism 1 is a braided mesh made of wire. The design of the flexible braided mesh reduces damage to the body cavity.

[0033] The expansion mesh 11-1 has various geometric shapes. The expansion mesh 11-1 can be made into various different shapes such as spherical, ellipsoidal, pear-shaped, etc. according to the shape of the body cavity.

[0034] The expansion mesh 11-1 is made from a medical-grade elastic material. The elastic properties of the medical-grade elastic material provide the expansion mesh 11-1 with excellent expansion force. In particular, when the expansion mesh 11-1 is released from the sheath tube 12, the expansion mesh 11-1, made from an elastic medical material, can easily return to its original shape. Furthermore, the elastic force provided by the medical-grade elastic material is gentle, exhibiting excellent cushioning when the expansion mesh 11-1 expands, preventing the expansion of the expansion mesh 11-1 from accidentally damaging surrounding tissues or organs.

[0035] The aforementioned expanded mesh 11-1 is made from medical-grade elastic stainless steel or medical-grade titanium-nickel shape memory alloy. Herein, the applicant has listed only the above two types of medical-grade elastic materials, but in actual application, a person skilled in the art may select and manufacture different medical-grade elastic materials as needed without departing from the scope of protection of this application.

[0036] The expansion mesh 11-1 is made from a transparent, elastic, medical-grade polymer material. The expansion mesh 11-1 may be made from a transparent, elastic, medical-grade polymer material, which ensures elastic buffering and does not obstruct the observation path of the camera 22-1, thereby improving the observation effect.

[0037] A coating is provided on the protective hood 20 of the observation mechanism 2. A hydrophobic coating can be selected as the coating, in which case liquids such as blood can quickly condense on the protective hood 20 and slide off as water droplets. A hydrophilic coating can also be selected, in which case liquids such as blood can quickly form a transparent water film on the surface of the protective hood 20 and not obstruct the camera.

[0038] The observation mechanism 2 is equipped with at least two cameras 22-1. By equipping the lens module 22 with at least two cameras 22-1, the problem of the limited field of view with conventional single-lens systems is effectively solved, and the field of view during the procedure can be effectively expanded. In particular, by equipping the cameras 22-1 to the front and sides of the operating mechanism 5, a three-dimensional observation space can be formed around the operating mechanism 5 by superimposing the fields of view, resulting in a very good clinical observation effect.

[0039] At least one of the cameras 22-1 is provided at the tip 5-1 of the operating mechanism 5. The camera 22-1, positioned in front of the operating mechanism 5, can effectively observe the area in front of the operating mechanism 5.

[0040] At least one of the cameras 22-1 is provided on the side surface 5-5 of the operating mechanism 5. The camera 22-1 provided on the side surface 5-5 of the operating mechanism 5 can observe the side surface of the operating mechanism 5.

[0041] The observation areas of two or more cameras 22-1 can be connected or partially overlap. When the observation areas of the cameras 22-1 provided at the tip 5-1 and side 5-5 of the operating mechanism 5 are connected, a spatial observation field can be formed, which enhances the clinical observation effect.

[0042] The observation mechanism 2 further comprises an instrument channel 25. The observation mechanism 2 may also be provided with the instrument channel 25, which can be used as the water supply channel 63 to clean the body cavity, and can also be used as a channel for inserting and removing surgical instruments, allowing for observation as well as various surgical procedures such as tissue washing, biopsy, electrocution, electrocoagulation, and excision.

[0043] The circuit system 3 is provided with an electrical interface 31 that connects to the host. The visualization medical system 100 with the body cavity expansion device is connected to the host and power supply via the electrical interface 31.

[0044] The visualization medical system 100 with the body cavity expansion device is equipped with an electronic protection mechanism 30. The electronic protection mechanism 30 is located outside the observation module 2 and / or the circuit system 3 and provides insulating protection to the electronic elements of the observation module 2 and / or the circuit system 3 by shielding them from moisture and gases. The electronic protection mechanism 30, located outside the observation module 2 and the circuit system 3, can provide insulating protection to the electronic elements of the observation module 2 and the circuit system 3 by shielding them from moisture and gases, effectively preventing blood or tissue fluid generated during the procedure from affecting the normal operation of the electronic elements, ensuring that the surgery proceeds smoothly and making the clinical procedure safer.

[0045] The electronic protection mechanism 30 is a protection mechanism 30-1 provided around the lighting module 21 and the lens module 22, or an insulating protective layer 30-2 provided outside the circuit system 3, or an insulating adhesive layer 30-3 provided inside the handle 52 to protect the image processing system 103.

[0046] A protective hood 20 is provided at the tip of the lighting module 21 and the lens module 22, and an isolator mount 25 is provided on the side rear of the lighting module 21 and the lens module 22. The protective hood 20, the isolator mount 25 and the case 24 form a sealed space by bonding or the like, constituting the protective mechanism 30-1, which completely isolates the lighting module 21 and the lens module 22 from human tissue, ensuring that blood or tissue fluid generated during the procedure does not affect the normal operation of the lighting module 21 and the lens module 22.

[0047] The waterproof and insulating protective layer 30-2 is provided over the entire exterior surface of the circuit system 3, effectively preventing unforeseen incidents such as short circuits that may occur due to blood or tissue fluid generated during the procedure.

[0048] When the signal processing module 23 is located within the handle 52, the area around the signal processing module 23 is filled with adhesive to form the insulating adhesive layer 30-3, thereby completely sealing and isolating the signal processing module 23 and the surrounding circuit system 3, achieving a protective purpose of shielding and insulating against moisture and gases.

[0049] The visualization medical system 100 with the body cavity expansion device further comprises an identification system 8. The identification system 8 can indicate the depth to which the operating mechanism 5 is inserted into the human body. The identification system 8 may be a scale 81 provided outside the operating mechanism 5, or it may be another identification method, which the applicant does not illustrate here, but none of these deviate from the scope of protection of this application.

[0050] The visualization medical system 100 with a body cavity expansion device further comprises a cleaning system 106. The water inlet 106-1 of the cleaning system 106 is connected to an infusion bottle / bag 7 via a water channel 106-4, and the water outlet 106-2 of the cleaning system 106 is connected to the water inlet 62 of the cleaning mechanism 6 of the visualization medical system 100 with a body cavity expansion device via a water channel 106-4. The cleaning system 106 can clean the visualization medical system 100 with a body cavity expansion device and surrounding tissues in a timely manner during the examination or procedure, ensuring that the observation field remains clean, and can also clean the surgical site in a timely manner, ensuring that it can be clearly observed during the examination and procedure, making the clinical procedure safer.

[0051] The cleaning system 106 is driven by a peristaltic pump 106-3. The peristaltic pump 106-3 can control the flow rate and speed of the water supply with greater precision. Of course, in actual application, those skilled in the art may also drive the cleaning system 106 with different drive devices without departing from the scope of protection of this application.

[0052] The visualization medical system 100 with a body cavity expansion device further comprises a negative pressure suction device 105. The suction outlet 42 of the negative pressure suction mechanism 4 of the visualization medical system 100 with a body cavity expansion device is connected to the negative pressure suction device 105. The visualization medical system 100 with a body cavity expansion device itself comprises the negative pressure suction device 105 and the washing system 106, integrating the negative pressure suction function and the washing function into a single device. This allows the entire procedure of artificial abortion to be completed under direct visualization with just one device, eliminating the need to rely on an external negative pressure source or external washing system. This significantly reduces the constraints and influences of the external environment on the procedure, resulting in a very wide range of applications.

[0053] In clinical applications, the observation mechanism 2 is placed inside the expansion mechanism 1, the expansion mesh 11-3 is housed inside the sheath tube 12, and the visualization medical system 100 with the body cavity expansion device is inserted into the body. When the sheath tube 12 is retracted, the expansion mesh 11-3 expands, expanding the body cavity at the front end of the observation mechanism 2, allowing the camera 22-1 to observe surrounding tissues and organs. When necessary, surgical instruments can be inserted into the body via the instrument channel 25 or the sheath tube 12 to perform various surgical procedures such as biopsy, electrocution, electrocoagulation, and excision. The cleaning mechanism 6 allows for timely cleaning of the camera 22-1 of the observation mechanism 2 and the body cavity, and the negative pressure suction mechanism 4 allows for timely suction of fluids such as tissue fluid, blood, and cleaning fluid to be discharged from the body.

[0054] The visualization medical system with a body cavity expansion device of the present invention comprises a body cavity expansion mechanism 1, an observation mechanism 2, a circuit system 3, a power supply system 104, an operating mechanism 5, and a display system 102. The body cavity expansion mechanism 1 is provided with an expansion end 11, which is located at the tip 5-1 of the operating mechanism 5, and expands the body cavity at the front end of the observation mechanism 2, thereby expanding the observation field of view of the observation mechanism 2. The observation mechanism 2 comprises a lighting module 21, a lens module 22, a signal processing module 23, and a case 24. Images and videos observed by the lens module 22 within the light field of the lighting module 21 are processed by the signal processing module 23, and then output to the display system 102 by the circuit system 3 for display. The lighting module 21, the lens module 22, and the circuit system 3 are connected and then sealed and installed inside the case 24. Because the body cavity at the front end of the observation mechanism 2 is expanded, the observation field of view of the lens module 22 is wider, resulting in a greater clinical observation effect. The visualization medical system with a body cavity expansion device of the present invention allows for the insertion of surgical instruments into the body through the sheath tube 12 while simultaneously performing observations. This enables various surgical procedures such as biopsy, electrocution, electrocoagulation, and excision to be performed while observing, making it extremely convenient for clinical use.

[Modes for carrying out the invention]

[0056] <Example 1: Visualization medical system with body cavity expansion device according to the present invention> Referring to Figures 1 to 1-2, the visualization medical system with a body cavity expansion device of this embodiment comprises a body cavity expansion mechanism 1, an observation mechanism 2, a circuit system 3, a power supply system 104, an operating mechanism 5, and a display system 102.

[0057] Referring to Figure 1, the body cavity expansion mechanism 1 comprises an expansion end 11 and a sheath tube 12, the sheath tube 12 being provided at the rear end of the expansion end 11. The sheath tube 12 comprises an inner sheath tube 12-1 and an outer sheath tube 12-2, and the expansion mesh 11-1 is compressible within the outer sheath tube 12-2.

[0058] The expansion end 11 is provided at the tip 5-1 of the operating mechanism 5, and expands the body cavity at the front end of the observation mechanism 2, thereby expanding the observation field of view of the observation mechanism 2.

[0059] In this embodiment, the expanded end 11 is an expanded mesh 11-1. The camera 22-1 can directly observe the area behind the expanded mesh 11-1 through the mesh-like gaps, and observation of the entire procedure and the entire surgical area is possible even if the expanded mesh 11-1 is not made of a transparent material.

[0060] The observation mechanism 2 comprises a lighting module 21, a lens module 22, a signal processing module 23, and a case 24. Images and videos observed by the lens module 22 within the light field of the lighting module 21 are processed by the signal processing module 23, and then output to the display system 102 by the circuit system 3 for display. The lighting module 21, the lens module 22, and the circuit system 3 are connected and then sealed and mounted inside the case 24.

[0061] Referring to Figure 6, the observation mechanism 2 and the display system 102 are connected to the power supply system 104 via the circuit system 3.

[0062] Referring to Figures 1-1 and 1-2, in this embodiment, the observation mechanism 2 and the body cavity expansion mechanism 1 are provided separately.

[0063] The observation mechanism 2 is an independent sealed device and can move back and forth within the channel 12-3 of the sheath tube 12 of the body cavity expansion mechanism 1. This design, which provides the observation mechanism 2 and the body cavity expansion mechanism 1 separately, allows the observation mechanism 2 to be fixed to the rear end or inside the expansion mesh 11-1 of the body cavity expansion mechanism 1 as needed, enabling very flexible use in clinical settings. Furthermore, after observation is complete in clinical use, the observation mechanism 2 can be collected, disinfected, sterilized, and reused, while the body cavity expansion mechanism 1 becomes disposable, significantly reducing the cost of clinical use.

[0064] The observation mechanism 2 and the body cavity expansion mechanism 1 may be integrated, in which case the sheath tube 12 of the body cavity expansion mechanism 1 constitutes the case 24. The illumination module 21, the lens module 22, and the circuit system 3 of the observation mechanism 2 are sealed inside the sheath tube 12. During clinical use, observation can be performed by directly inserting the visualization medical system 100 with the body cavity expansion device into the body, making it easy and convenient to operate in clinical use.

[0065] In this embodiment, the camera 22-1 of the lens module 22 is provided at the rear end of the extended mesh 11-1, and the extended mesh 11-1 is within the field of view of the camera 22-1.

[0066] The technical solution of post-positioning the camera 22-1 ensures that the extended mesh 11-1 is entirely within the field of view of the camera 22-1, and since the observation angle of the camera 22-1 is angled forward of the surgical or examination area, there are no blind spots during the procedure described above. The technical solution of post-positioning the camera makes clinical examinations and procedures safer and more effective.

[0067] Referring to Figure 1, in this embodiment, the expansion mesh 11-1 is a mesh structure formed by winding two wires. In actual application, the expansion mesh 11-1 of the body cavity expansion mechanism 1 may be a braided mesh made from wires. The design of a flexible braided mesh further reduces damage to the body cavity.

[0068] The expanded mesh 11-1 has various geometric shapes. Depending on the shape of the body cavity, the expanded mesh 11-1 can be made into various different shapes such as a sphere, ellipsoid, or pear shape.

[0069] The expansion mesh 11-1 is made from a medical-grade elastic material. The elastic properties of the medical-grade elastic material provide the expansion mesh 11-1 with excellent expansion force. In particular, when the expansion mesh 11-1 is released from the sheath tube 12, the expansion mesh 11-1, made from an elastic medical material, can easily return to its original shape. Furthermore, the elastic force provided by the medical-grade elastic material is gentle, exhibiting excellent cushioning when the expansion mesh 11-1 expands, preventing the expansion of the expansion mesh 11-1 from accidentally damaging surrounding tissues or organs.

[0070] The aforementioned expanded mesh 11-1 is made from medical-grade elastic stainless steel or medical-grade titanium-nickel shape memory alloy. Herein, the applicant has listed only the above two types of medical-grade elastic materials, but in actual application, a person skilled in the art may select and manufacture different medical-grade elastic materials as needed without departing from the scope of protection of this application.

[0071] The expansion mesh 11-1 is made from a transparent, elastic, medical-grade polymer material. The expansion mesh 11-1 may be made from a transparent, elastic, medical-grade polymer material, which ensures elastic buffering and does not obstruct the observation path of the camera 22-1, thereby improving the observation effect.

[0072] The circuit system 3 is provided with an electrical interface 31 that connects to the host. The visualization medical system 100 with the body cavity expansion device is connected to the host and power supply via the electrical interface 31.

[0073] The visualization medical system 100 with the body cavity expansion device further comprises an identification system 8. The identification system 8 can indicate the depth to which the operating mechanism 5 is inserted into the human body. The identification system 8 may be a scale 81 provided outside the operating mechanism 5, or it may be another identification method, which the applicant does not illustrate here, but none of these deviate from the scope of protection of this application.

[0074] In this embodiment, the visualization medical system with a body cavity expansion device is provided with an expansion end 11 of the body cavity expansion mechanism 1 at the tip of the camera 22-1 of the observation mechanism 2. The expansion end 11 expands the body cavity at the front end of the observation mechanism 2, thereby expanding the observation field of view of the observation mechanism 2, making it particularly suitable for examinations and procedures such as hysteroscopy and colonoscopy. When in use, the visualization medical system with a body cavity expansion device of the present invention is inserted into the body cavity, the expansion end 11 expands the body cavity, and the observation mechanism 2 observes the expanded area. The image and video signal observed by the lens module 22 are output to the display system 102 by the circuit system 3 and displayed. Because the body cavity at the front end of the observation mechanism 2 is expanded, the observation field of view of the lens module 22 becomes wider, and the clinical observation effect is enhanced. <Example 2: Visualization medical system with body cavity expansion device of the present invention, equipped with a negative pressure suction mechanism and a cleaning mechanism>

[0075] Referring to Figures 2 to 2-4, the difference between this embodiment and Embodiment 1 is that in this embodiment, the visualization medical system 100 with the body cavity expansion device further includes a negative pressure suction mechanism 4 and a cleaning mechanism 6.

[0076] Referring to Figure 2-1, the sheath tube 12 comprises an inner sheath tube 12-1 and an outer sheath tube 12-2, and the expansion mesh 11-1 is compressible within the outer sheath tube 12-2. The inner sheath tube 12-1 is a triple lumen tube, with the observation mechanism 2 provided in the first lumen tube, the second lumen tube constituting the suction channel 43 or having the suction channel 43 provided, and the third lumen tube constituting the water supply channel 63 of the cleaning mechanism 6 or being used for inserting and removing surgical instruments.

[0077] The negative pressure suction mechanism 4 comprises a suction inlet 41, a suction outlet 42, and a suction channel 43. The suction inlet 41 is located at the tip of the inner sheath tube 12-1, and the suction outlet 42 of the negative pressure suction mechanism 4 is located at the rear end of the inner sheath tube 12-1. The dual-lumen channel design allows the circuit system 3 to be isolated from fluids such as blood and tissue fluid that may occur during surgery, thereby more effectively avoiding safety hazards such as short circuits and electrical leakage during use, and making the clinical use process safer.

[0078] The negative pressure suction mechanism 4 is provided with a negative pressure control switch 44 that can control the negative pressure state. The negative pressure control switch 44 can turn the negative pressure suction mechanism 4 on and off, and can also adjust the negative pressure suction force of the negative pressure suction mechanism 4 according to the amount of detached tissue, blood, and tissue fluid in the uterus during the procedure. In clinical use, the physician can easily adjust the negative pressure suction force to the desired level, thereby avoiding situations where the negative pressure suction force is too low to remove the detached tissue in a timely manner, or where the negative pressure is too high and accidentally damages tissues such as the endometrium.

[0079] The negative pressure control switch 44 is provided on the handle 52 of the operating mechanism 5. By providing the negative pressure control switch 44 on the handle 52, medical staff can operate it with one hand during clinical use, making the process of use more convenient.

[0080] The cleaning mechanism 6 includes a water outlet 61, a water inlet 62, and a water supply channel 63.

[0081] Referring to Figures 2-1 and 2-2, at least one outlet 61 of the cleaning mechanism 6 is located at the tip of the camera 22-1 of the lens module 22. During the examination and procedure, the cleaning mechanism 6 can clean the camera 22-1, allowing for the timely removal of blood at the tip of the camera 22-1 by washing, ensuring that the observation field remains clean. The cleaning mechanism 6 can also clean the inside of body cavities in a timely manner, particularly surgical sites, allowing for timely observation of the surgical or examination site, ensuring the safety of the surgical or examination process, and making the clinical procedure safer.

[0082] The water inlet 62 of the cleaning mechanism 6 is provided at the rear end of the inner sheath tube 12-1. The triple lumen channel design ensures that the circuit system 3 is isolated and protected, and also allows for the separation of the cleaning channel and the suction channel, thereby more effectively ensuring that aspirated tissue or fluid does not flow back into the uterus during cleaning, making the process more efficient and safer.

[0083] The cleaning mechanism 6 is provided with a flushing switch 64 for controlling the cleaning water. The flushing switch 64 can turn the cleaning mechanism 6 on and off, and can also control the volume and pressure of the cleaning water. During clinical use, clinicians can turn the cleaning mechanism 6 on or off according to the actual requirements of the procedure and select the appropriate volume and pressure of the cleaning water as needed, making the clinical use process more convenient.

[0084] The flashing switch 64 is provided on the handle 52 of the operating mechanism 5. By providing the flashing switch 64 on the handle 52, medical staff can operate it with one hand during clinical use, making the process of use more convenient.

[0085] Referring to Figures 2-1, 2-3, and 2-4, the visualization medical system 100 with the body cavity expansion device is equipped with an electronic protection mechanism 30. The electronic protection mechanism 30 is located outside the observation module 2 and / or the circuit system 3 and provides insulating protection to the electronic elements of the observation module 2 and / or the circuit system 3 by shielding them from moisture and gases. The electronic protection mechanism 30, located outside the observation module 2 and the circuit system 3, can provide insulating protection to the electronic elements of the observation module 2 and the circuit system 3 by shielding them from moisture and gases, effectively preventing blood or tissue fluid generated during the procedure from affecting the normal operation of the electronic elements, ensuring that the surgery proceeds smoothly and making the clinical procedure safer.

[0086] The electronic protection mechanism 30 is a protection mechanism 30-1 provided around the lighting module 21 and the lens module 22, or an insulating protective layer 30-2 provided outside the circuit system 3, or an insulating adhesive layer 30-3 provided inside the handle 52 to protect the image processing system 103.

[0087] A protective hood 20 is provided at the tip of the lighting module 21 and the lens module 22, and an isolator mount 25 is provided on the side rear of the lighting module 21 and the lens module 22. The protective hood 20, the isolator mount 25 and the case 24 form a sealed space by bonding or the like, constituting the protective mechanism 30-1, which completely isolates the lighting module 21 and the lens module 22 from human tissue, ensuring that blood or tissue fluid generated during the procedure does not affect the normal operation of the lighting module 21 and the lens module 22.

[0088] The waterproof and insulating protective layer 30-2 is provided over the entire exterior surface of the circuit system 3, effectively preventing unforeseen incidents such as short circuits that may occur due to blood or tissue fluid generated during the procedure.

[0089] When the signal processing module 23 is located within the handle 52, the area around the signal processing module 23 is filled with adhesive to form the insulating adhesive layer 30-3, thereby completely sealing and isolating the signal processing module 23 and the surrounding circuit system 3, achieving a protective purpose of shielding and insulating against moisture and gases.

[0090] In this embodiment, the cleaning mechanism 6 can clean the camera 22-1 and the body cavity, and the negative pressure suction mechanism 4 can quickly aspirate and discharge from the body fluids such as tissue fluid, blood, and cleaning fluid generated during examination or surgery, allowing for clearer observation and greater safety during clinical use. <Example 3: Visualization medical system with a body cavity expansion device of the present invention, with adjustable observation direction>

[0091] Referring to Figures 3 to 3-5, the difference between this embodiment and Embodiment 1 is that in this embodiment, the camera 22-1 of the lens module 22 is located inside the scraping device 11.

[0092] In this embodiment, the camera 22-1 of the lens module 22 is provided inside the scraping device 11.

[0093] Referring to Figures 3 and 3-1, the observation direction of the camera 22-1 of the lens module 22 is adjustable. By adjusting the observation direction of the camera 22-1, the condition of the surrounding tissue can be observed comprehensively, resulting in a more complete observation in clinical use.

[0094] An adjustment mechanism 22-11 for adjusting the observation direction of the camera 22-1 is provided on the handle 52 of the operating mechanism 5. By providing the adjustment mechanism 22-11 on the handle 52, the observation direction of the camera 22-1 can be easily adjusted from outside the body during clinical use, making operation easier.

[0095] Referring to Figures 3-2 and 3-3, the operating direction of the expansion end 11 is adjustable. The operating direction of the expansion end 11 can be adjusted as needed to better fit the structure and shape of the surrounding body cavity, and the clinical effectiveness is better, especially in areas that are difficult to clean or observe, such as the corners of the uterus.

[0096] A rocking mechanism 11-4 for adjusting the operating direction of the extended end 11 is provided on the handle 52. By providing the rocking mechanism 11-4 on the handle 52, the operating direction of the operating part of the curettage device 11 can be easily adjusted from outside the body during clinical use, making operation easier.

[0097] Referring to Figures 3-4 and 3-5, the observation direction of the camera 22-1 of the lens module 22 and the operating direction of the extension end 11 can be adjusted simultaneously. In actual application, a clinician can adjust either the observation direction of the camera 22-1 or the operating direction of the extension end 11 as needed, or they can adjust both the observation direction of the camera 22-1 and the operating direction of the extension end 11 simultaneously.

[0098] When simultaneously adjusting the observation direction of the camera 22-1 and the operating direction of the extension end 11, the adjustment mechanism 22-11 and the swing mechanism 11-4 can be combined into a single adjustment mechanism and provided on the handle 52.

[0099] In this embodiment, since the observation direction of the camera 22-1 and the operating direction of the expansion mesh 11 are adjustable, the clinical effectiveness is improved, especially in corners where cleaning and observation are difficult during clinical use. <Example 4: Visualization medical system with body cavity expansion device of the present invention equipped with multiple cameras>

[0100] Referring to Figures 4 and 4-1, the difference between this embodiment and Embodiment 1 is that in this embodiment, the lens module 22 includes at least two cameras 22-1.

[0101] The lens module 22, equipped with at least two cameras 22-1, effectively solves the problem of limited observation field with conventional single-lens systems and effectively expands the observation field during the procedure. In particular, by providing the cameras 22-1 in front of and on the side of the operating mechanism 5, the superposition of observation fields creates a three-dimensional observation space around the operating mechanism 5, resulting in excellent clinical observation results.

[0102] At least one of the cameras 22-1 is provided at the tip 5-1 of the operating mechanism 5. The camera 22-1, positioned in front of the operating mechanism 5, can effectively observe the area in front of the operating mechanism 5.

[0103] At least one of the cameras 22-1 is provided on the side surface 5-5 of the operating mechanism 5. The camera 22-1 provided on the side surface 5-5 of the operating mechanism 5 can observe the side surface of the operating mechanism 5.

[0104] The observation areas of two or more cameras 22-1 can be connected or partially overlap. When the observation areas of the cameras 22-1 provided at the tip 5-1 and side 5-5 of the operating mechanism 5 are connected, a spatial observation field can be formed, which enhances the clinical observation effect.

[0105] In this embodiment, the lens module 22 is equipped with at least two cameras 22-1, which effectively solves the problem of limited observation field with conventional single-lens systems and effectively expands the observation field during the procedure. In particular, by providing the cameras 22-1 in front of and on the side of the operating mechanism 5, a three-dimensional observation space can be formed around the operating mechanism 5 by superimposing the observation fields, resulting in a very good clinical observation effect. <Example 5: Visualization medical system with a body cavity expansion device of the present invention equipped with an instrument channel>

[0106] Referring to Figures 5 and 5-1, the difference between this embodiment and Embodiment 1 is that in this embodiment, the observation mechanism 2 is equipped with an instrument channel 25.

[0107] Referring to Figures 5 and 5-1, the observation mechanism 2 is provided with the instrument channel 25 and the water supply channel 63. Surgical instruments can be inserted into the body through the instrument channel 25, and various surgical procedures such as biopsy, electrocution, electrocoagulation, and laser excision can be performed as needed. The outlet 61 of the water supply channel 63 is located near the camera 22-1, allowing for timely cleaning of the camera 22-1 and surrounding body cavity tissue. The negative pressure suction mechanism 4 timely aspirates and discharges from the body any fluids such as tissue fluid, blood, and cleaning fluid generated during the cleaning and procedure process.

[0108] The visualization medical system with a body cavity expansion device in this embodiment allows for effective observation and enables various surgical procedures as needed, thus broadening its range of clinical use. <Example 6: Visualization medical system with body cavity expansion device of the present invention, equipped with a cleaning system>

[0109] Referring to Figure 7, the difference between the visualization medical system with a body cavity expansion device in this embodiment and that in Embodiment 1 is that in this embodiment, the visualization medical system with a body cavity expansion device further includes a cleaning system 106.

[0110] The water inlet 106-1 of the washing system 106 is connected to the infusion bottle / bag 7 via the water channel 106-4, and the water outlet 106-2 of the washing system 106 is connected to the water inlet 62 of the washing mechanism 6 of the visualization medical system with the body cavity expansion device via the water channel 106-4. The washing system 106 can timely wash the visualization medical system with the body cavity expansion device equipped with the electronic protection mechanism and the surrounding tissues during the procedure, ensuring that the observation field is kept clean and the surgical site can be timely washed, thereby allowing timely observation of whether the embryonic tissue has been completely cleaned from the implantation site, ensuring the integrity of the embryonic tissue during the induced abortion procedure, effectively avoiding situations where the induced abortion is incomplete, and making the clinical procedure safer.

[0111] Referring to Figure 10, the cleaning system 106 is driven by a peristaltic pump 106-3. The peristaltic pump 106-3 can control the flow rate and speed of the water supply with greater precision. Of course, in actual application, those skilled in the art may also drive the cleaning system 106 with different drive devices without departing from the scope of protection of this application.

[0112] In this embodiment, the cleaning system 106 can clean the visualization medical system with the body cavity expansion device and surrounding tissues in a timely manner during the procedure, ensuring that the observation field remains clean and the surgical site is cleaned in a timely manner, making it safer for clinical use. <Example 7: Visualization medical system with a body cavity expansion device of the present invention equipped with a negative pressure source>

[0113] Referring to Figure 8, the difference between the direct visualization artificial abortion curettage system of this embodiment and that of Embodiment 6 is that in this embodiment, the direct visualization artificial abortion curettage system further includes a negative pressure suction device 105.

[0114] In this embodiment, the suction outlet 42 of the negative pressure suction mechanism 4 of the visualization medical system with the body cavity expansion device is connected to the negative pressure suction device 105. The water inlet 106-1 of the cleaning system 106 is connected to the infusion bottle bag 7 via tube 7-1, and the water outlet 106-2 of the cleaning system 106 is connected to the water inlet 62 of the cleaning mechanism 6 via tube 7-1.

[0115] When used clinically, by connecting the suction outlet 42 of the negative pressure suction mechanism 4 to the negative pressure suction device 105, the negative pressure suction device 105 can continuously aspirate and expel from the body tissue and blood that have been removed during surgery during the procedure.

[0116] The visualization medical system with a body cavity expansion device in this embodiment itself is equipped with the negative pressure suction device 105 and the cleaning system 106, and the negative pressure suction function and the cleaning function are integrated into a single device, so that the entire procedure of artificial abortion can be completed under direct visualization with just one device, there is no need to rely on an external negative pressure source or an external cleaning system, the constraints and influences of the external environment on the procedure are greatly reduced and the range of application is very wide.

[0117] It should be noted that the structures disclosed and described herein may be replaced by other structures having the same effect, and the embodiments described herein are not the only structures that realize the present invention. Although preferred embodiments of the present invention have been introduced and described herein, these embodiments are merely illustrative, and it will be apparent to those skilled in the art that many modifications, improvements, and substitutions are possible without departing from the present invention. Accordingly, the scope of protection of the present invention is determined by the spirit and scope of the claims appended to the present invention. [Explanation of symbols]
