TECHNICAL FIELD

[0001] The present application relates to the technical field of endoscopic treatment auxiliary equipment, in particular to a detachable multipurpose endoscopic treatment auxiliary device. BACKGROUND

[0002] With the development of endoscopic minimally invasive technology, some digestive tract lesions, such as early digestive tract tumors, can be safely and effectively removed under endoscopy. Compared with surgical operation, endoscopic minimally invasive technology has small trauma and is simple and fast. Endoscopes are divided into therapeutic endoscopes with forceps channel openings and diagnostic endoscopes without forceps channel openings.

[0003] Currently, the cost of therapeutic endoscopes is generally 20%-25% higher than that of diagnostic endoscopes. Most hospitals have previously equipped a large number of diagnostic endoscopes for basic lesion screening. If therapeutic endoscopes are directly replaced to meet the needs of clinical diagnosis and treatment integration, not only will the overall use cost of the hospital increase due to the significant increase in equipment procurement cost, but also the diagnostic endoscopes that still have use value will be in a long-term idle state.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Hospitals do not need to replace expensive therapeutic endoscopes. They can be directly adapted to existing diagnostic endoscopes, effectively avoiding the problem of a large number of diagnostic endoscopes being idle and wasted due to their single function. Through the combination of "diagnostic endoscope + auxiliary device", the needs of integrated clinical diagnosis and treatment can be met, while significantly reducing equipment procurement expenditures. This alleviates the dual pressure of hospital equipment management and cost control, allowing existing medical equipment resources to fully play their clinical value and improve overall resource utilization efficiency.

[0019] 2. Through the multi-cavity design of the main tube, including the water inlet cavity, treatment cavity, and visual cavity, it integrates multiple functions such as endoscope fixation, field irrigation, angle adjustment, and diagnostic lighting. The annular airbag and fixation components work together to achieve synchronous fixation of the endoscope and irrigation components, ensuring equipment stability. The arc-shaped baffle guides the irrigation fluid to precisely clean the transparent plate and LED light. Combined with the sufficient illumination of the LED light, it ensures a clear endoscopic field of view. The adjustment component achieves precise angle adjustment of the end of the main tube through the winding coil of the reverse-wound traction line, adapting to different diagnostic and treatment scenarios. The multi-functional collaboration reduces the use of additional auxiliary equipment, simplifies the diagnostic and treatment process, and improves the convenience of operation and the accuracy of diagnosis and treatment.

[0020] 3. The sealing ring on the fixed plate adopts a dynamic sealing structure, which always maintains a tight fit with the inner wall of the second mounting groove when sliding with the fixed plate, avoiding gas leakage and ensuring stable linkage function. The transparent plate physically isolates the endoscope lens from the patient's body fluids, preventing the lens from being contaminated and corroded, and extending the service life of the endoscope. The gap design between the external toothed ring and the water inlet cavity ensures smooth assembly of the rinsing components and prevents component displacement through the locking block. The baffle automatically resets and closes the water inlet cavity outlet after the water supply stops, preventing external contaminants from entering and facilitating disassembly between the main tube and the rinsing components. This improves the durability of the device itself, reduces the risk of endoscope contamination and maintenance costs, and ensures the safety of diagnosis and treatment. Attached Figure Description

[0038] An embodiment provided by the application is a separable multipurpose endoscopic treatment auxiliary device, which comprises a main tube 1, an inlet water cavity 11, a treatment cavity 12, a visible cavity 13, an inlet gas cavity 14 and a traction cavity 17 are arranged in the main tube 1, a first mounting groove 15 is arranged on the inner wall of the visible cavity 13, a ring-shaped air bag 151 is arranged on the inner wall of the first mounting groove 15, a second mounting groove 16 is arranged on the inner wall of the inlet water cavity 11, the inlet gas cavity 14, the first mounting groove 15 and the second mounting groove 16 are communicated, a fixing assembly 2 is arranged in the second mounting groove 16, an adjusting assembly 5 is arranged on the outer side wall of one end of the main tube 1, and a flushing assembly 3 is arranged at the end of the inlet water cavity 11 away from the adjusting assembly 5, in the embodiment, the ring-shaped air bag 151 is made of medical silicon rubber.

[0039] The fixing assembly 2 comprises a fixing plate 21 movably connected to the inner wall of the second mounting groove 16, a clamping block 22 fixedly connected to the middle part of the lower surface of the fixing plate 21, and two first springs 23 fixedly connected to the lower end of the fixing plate 21 and located on the left and right sides of the clamping block 22 respectively, and the lower end of each first spring 23 is fixedly connected to the inner wall of the second mounting groove 16.

[0040] Specifically, the diagnostic endoscope is arranged in the visible cavity 13 of the main tube 1, the endoscope lens is abutted against the fixed transparent plate 4 on the inner wall of the end of the visible cavity 13 away from the adjusting assembly 5, the initial positioning of the endoscope is completed, then the external thread cylinder 31 of the flushing assembly 3 is threadedly connected to the inner wall of the inlet water cavity 11, the external tooth ring 32 at one end of the external thread cylinder 31 is inserted into the inside of the inlet water cavity 11 until the external tooth ring 32 moves to the position corresponding to the clamping block 22 of the fixing assembly 2, then the gas is introduced into the inlet gas cavity 14 through the inlet gas connector 19, the gas flows into the first mounting groove 15 and the second mounting groove 16 along the inlet gas cavity 14 channel respectively, the gas entering the first mounting groove 15 makes the ring-shaped air bag 151 swell, the inner wall of the swollen ring-shaped air bag 151 is tightly attached to the outer wall of the endoscope in the visible cavity 13, the stable fixing of the endoscope is realized, at the same time, the gas entering the second mounting groove 16 pushes the fixing plate 21 to slide downward against the elastic force of the first spring 23, the clamping block 22 on the lower surface of the fixing plate 21 is clamped with the external tooth ring 32, the fixing of the flushing assembly 3 and the inlet water cavity 11 is completed, finally, the double fixing of the endoscope and the flushing assembly 3 is realized synchronously through single inflation operation, and the linkage effect of the endoscope and the flushing assembly 3 is achieved.

[0041] ​The flushing assembly 3 comprises an outer threaded cylinder 31 threadedly connected with the inner wall of the water inlet cavity 11, one end of the outer threaded cylinder 31 is fixedly connected with an outer gear ring 32, one end of the outer threaded cylinder 31 away from the outer gear ring 32 is provided with a third mounting groove 33, the inner wall of the third mounting groove 33 is fixedly connected with a second spring 34, one end of the second spring 34 is fixedly connected with a connecting plate 35, the side wall of the connecting plate 35 close to one end of the second spring 34 is slidingly connected with the inner wall of the third mounting groove 33, one end of the connecting plate 35 away from the second spring 34 is fixedly connected with a baffle 36, in the embodiment, the baffle 36 can be made of medical grade polytetrafluoroethylene.

[0042] Specifically, when the flushing function is started, the external flushing liquid enters the water inlet cavity 11 of the main pipe 1 through the water inlet joint 18, as the liquid pressure in the water inlet cavity 11 gradually rises, the water flow will generate an outward pushing force on the arc-shaped baffle 36 of the flushing assembly 3, the pushing force overcomes the elastic tension of the second spring 34, pushes the baffle 36 to drive the connecting plate 35 to slide along the inner wall of the third mounting groove 33 of the outer threaded cylinder 31, so that the baffle 36 is away from the end of the main pipe 1, at this time, the flushing liquid in the water inlet cavity 11 flows out along the channel of the outer threaded cylinder 31, and under the guidance of the arc-shaped baffle 36, sprays to the surface of the transparent plate 4 at the end of the visible cavity 13 and the surface of the LED lamp 61 in the fourth mounting groove 6, washes away the attached body fluid, impurities and other obstructions, and ensures clear endoscopic vision, when the water supply to the water inlet cavity 11 is stopped, the liquid pressure in the water inlet cavity 11 disappears, the second spring 34 restores the initial elastic deformation, drives the baffle 36 to slide reversely and reset, re-closes the outlet end of the outer threaded cylinder 31, and avoids external pollutants from entering the inside of the water inlet cavity 11.

[0043] The adjusting assembly 5 comprises an adjusting seat 51 fixedly connected with the side wall of the main pipe 1 away from the flushing assembly 3, one end of the traction cavity 17 away from the flushing assembly 3 is in communication with the inner wall of the adjusting seat 51, the adjusting seat 51 is movably connected with a rotating column 52, the side wall of the middle part of the rotating column 52 is fixedly sleeved with a worm gear 53, the side wall of the worm gear 53 is meshingly connected with a worm shaft 54, the two sides of the middle part of the rotating column 52 are respectively fixedly sleeved with a winding disc 55, the winding disc 55 is provided with a traction line 56, one end of the traction line 56 away from the winding disc 55 is fixedly connected with the inner wall of one end of the traction cavity 17 away from the adjusting assembly 5.

[0044] Specifically, when the angle of the main tube 1 away from one end of the adjusting assembly 5 needs to be adjusted to adapt to the diagnosis and treatment field of view, the operator holds the handle 58 at the lower end of the adjusting seat 51 to keep the device stable, rotates the driving block 57 at the end of the worm 54 to drive the worm 54 to rotate, and since the worm 54 is engaged with the worm gear 53 of the fixed sleeve in the middle of the rotating column 52, the rotating force of the worm 54 is converted into the torque of the worm gear 53, which drives the rotating column 52 to rotate around its own axis in the inner wall of the adjusting seat 51, and the rotating column 52 synchronously drives the wire winding discs 55 fixedly sleeved on its two sides to rotate in the same direction, and since the winding directions of the traction lines 56 on the side walls of the two wire winding discs 55 are opposite to each other, one wire winding disc 55 winds the traction line 56, and the other wire winding disc 55 synchronously releases the traction line 56, one end of the traction line 56 away from the wire winding disc 55 is fixedly connected with the inner wall of one end of the traction cavity 17 away from the adjusting assembly 5, and the tension difference between the pulling force of the winding side traction line 56 and the relaxation state of the releasing side traction line 56 is formed, which is transmitted to the end of the main tube 1 through the traction cavity 17, and finally drives the end of the main tube 1 away from the adjusting assembly 5 to bend and rotate in the direction of the winding side traction line 56, thereby realizing precise adjustment of the diagnosis and treatment angle.

[0045] The inner wall of one end of the visual cavity 13 away from the adjusting assembly 5 is fixedly connected with a transparent plate 4, and the end of the main tube 1 away from the adjusting assembly 5 is uniformly provided with two fourth mounting grooves 6, and the inner wall of the fourth mounting groove 6 is provided with an LED lamp 61. In this embodiment, the transparent plate 4 can be made of medical-grade high borosilicate glass.

[0046] Specifically, in the process of using the device, the transparent plate 4 fixedly connected with the inner wall of one end of the visual cavity 13 away from the adjusting assembly 5 directly contacts with the tissue fluid in the patient's body, and the endoscope lens placed in the visual cavity 13 only abuts against the inner surface of the transparent plate 4. Through the physical isolation effect of the transparent plate 4, the endoscope lens is prevented from directly contacting with the body fluid, thereby preventing the body fluid from adhering to the lens to cause the vision to be blurred, and reducing the risk of the endoscope lens being contaminated and corroded. In addition, the two fourth mounting grooves 6 uniformly provided at the end of the main tube 1 away from the adjusting assembly 5 are both provided with LED lamps 61, and the light directly irradiates to the diagnosis and treatment area in the patient's body, thereby providing sufficient illumination environment for the endoscope. In combination with the light transmission of the transparent plate 4, it is ensured that the endoscope can clearly capture the image of the diagnosis and treatment area, thereby ensuring the accurate implementation of the endoscopic diagnosis and treatment operation.

[0047] The water inlet cavity 11 away from the flushing assembly 3 is provided with a water inlet connector 18 connected through a connecting pipe, and the air inlet cavity 14 away from the fixing assembly 2 is provided with an air inlet connector 19 connected through a connecting pipe.

[0048] Specifically, the water inlet joint 18 of the device is communicated with the water inlet cavity 11 of the main pipe 1 away from the flushing assembly 3 through the connecting pipe, and the water inlet joint 18 is connected with the external water inlet equipment in use. The external water inlet equipment transports the flushing liquid to the water inlet cavity 11 through the water inlet joint 18, provides the liquid source for the subsequent flushing assembly 3 to realize the flushing function of the transparent plate 4 and the surface shielding object of the LED lamp 61, and simultaneously, the air inlet joint 19 is communicated with the air inlet cavity 14 of the main pipe 1 away from the fixing assembly 2 through the connecting pipe. After the air inlet joint 19 is connected with the external air inlet equipment, the external air inlet equipment can transport the gas to the air inlet cavity 14 through the air inlet joint 19. The gas flows to the first mounting groove 15 and the second mounting groove 16 through the air inlet cavity 14, and provides the power for the annular air bag 151 to expand, the endoscope to be fixed, and the clamping block 22 of the fixing assembly 2 to clamp and fix the flushing assembly 3.

[0049] The fixing plate 21 is provided with a placing groove 24 in the side wall, and the inner wall of the placing groove 24 is provided with a sealing ring 25. In the embodiment, the sealing ring 25 belongs to dynamic sealing and can be made of medical-grade silicone rubber.

[0050] Specifically, the fixing plate 21 of the fixing assembly 2 is provided with a placing groove 24 in the side wall, and the sealing ring 25 is embedded in the placing groove 24. The outer side wall of the sealing ring 25 is tightly combined with the inner wall of the second mounting groove 16. When the air inlet cavity 14 is filled with gas to push the fixing plate 21 to slide up and down along the inner wall of the second mounting groove 16, the sealing ring 25 moves synchronously with the fixing plate 21 and always maintains the tightly contacted state with the inner wall of the second mounting groove 16. The sealing ring 25 can effectively block the gas in the second mounting groove 16 from leaking from the gap between the fixing plate 21 and the second mounting groove 16, ensures that the gas can fully act on the annular air bag 151 to expand and the fixing plate 21 to drive, and guarantees the linkage stability of the endoscope fixation and the fixing of the flushing assembly 3.

[0051] The winding directions of the two sides of the traction line 56 of the side wall of the two winding reels 55 are opposite to each other, the two winding reels 55 fixedly sleeved on the middle part of the rotating column 52 of the adjusting assembly 5 have the traction line 56 of the side wall wound in opposite directions, that is, one winding reel 55 winds the traction line 56 clockwise, and the other winding reel 55 winds the traction line 56 counterclockwise, when the worm 54 drives the worm gear 53 to drive the rotating column 52 to rotate, the two winding reels 55 rotate synchronously and in the same direction with the rotating column 52, at this time, one winding reel 55 winds the traction line 56 due to the matching of the winding direction and the rotating direction, so that the length of the traction line 56 on this side is shortened and a pulling force is generated, and the other winding reel 55 unwinds the traction line 56 due to the opposite winding direction and the rotating direction, so that the length of the traction line 56 on this side is lengthened and remains in a relaxed state, since the ends of the two sides of the traction line 56 away from the winding reel 55 are fixedly connected to the inner wall of the end of the traction cavity 17 away from the adjusting assembly 5, the tension difference between the pulling of the traction line 56 on the winding side and the relaxed state of the traction line 56 on the unwinding side is transmitted to the end of the main body pipe 1 through the traction cavity 17, and finally the end of the main body pipe 1 away from the adjusting assembly 5 is pulled to bend and rotate in the direction of the traction line 56 on the winding side, so that the precise adjustment of the diagnosis and treatment angle of the device is realized.

[0052] One end of the worm 54 penetrates through the outer side wall of the adjusting seat 51, and the end of the worm 54 outside the adjusting seat 51 is fixedly connected with a driving block 57. The lower end of the adjusting seat 51 is fixedly connected with a handle 58.

[0053] A gap is left between the outer side wall of the external tooth ring 32 and the inner wall of the water inlet cavity 11, and the lower end of the clamping block 22 is connected with the external tooth ring 32 in a clamping manner. During the assembly of the flushing assembly 3 and the water inlet cavity 11 of the main body pipe 1, the external tooth ring 32 at one end of the external thread cylinder 31 is inserted into the inside of the water inlet cavity 11 synchronously with the external thread cylinder 31. Since a gap is left between the outer side wall of the external tooth ring 32 and the inner wall of the water inlet cavity 11, the external tooth ring 32 can avoid being unable to be smoothly inserted into the water inlet cavity 11 due to size error or assembly deviation, and at the same time, a certain radial movement space is provided for the external tooth ring 32, so that the external tooth ring 32 can be accurately moved to the corresponding position of the clamping block 22 of the fixed assembly 2. When the air inlet cavity 14 is connected with gas to push the fixed plate 21 to move downward, the clamping block 22 on the lower surface of the fixed plate 21 moves downward synchronously and is accurately clamped in the tooth groove of the external tooth ring 32. At this time, the gap between the external tooth ring 32 and the water inlet cavity 11 does not affect the clamping accuracy of the clamping block 22, and at the same time, the clamping block 22 can limit the external tooth ring 32 to prevent the external thread cylinder 31 from rotating or axially deviating in the water inlet cavity 11. Finally, the external tooth ring 32 is smoothly inserted, and the stable fixation of the flushing assembly 3 and the water inlet cavity 11 is realized.

[0054] The arc-shaped baffle 36 is first impacted by the water flow on the inner curved surface when the external flushing liquid enters the water inlet cavity 11 through the water inlet joint 18 and flows to the flushing assembly 3. The arc-shaped structure can buffer the water flow impact force through the curved surface, avoid splashing caused by direct water jetting, and utilize the guiding effect of the curved surface to deflect the water flow originally flowing axially along the water inlet cavity 11 to the left and right and obliquely downward, so that the water flow direction covers the surface of the transparent plate 4 at the end of the visible cavity 13 and the surface of the LED lamp 61 in the fourth mounting groove 6 at the end of the main body pipe 1. Through the change and guidance of the water flow direction by the arc-shaped baffle 36, it can be ensured that the flushing liquid uniformly acts on the key areas of the transparent plate 4 and the LED lamp 61, removes the attached body fluids, impurities and other obstructions, ensures the clear endoscopic vision, and avoids unnecessary interference of the water flow on the diagnosis and treatment area.
