An auxiliary pressurization device for colonoscopy

Abstract

The application provides an auxiliary pressing device for colonoscopy, which comprises an adjusting slide rail, an arched support beam and a pressing gun. In use, the arched support beam is adjusted to a proper position, and then the position and angle of the pressing gun on the arched support beam are adjusted according to the required pressing area. After adjustment, the operator presses the control button to drive the output push rod to extend outward, and the pressing disc is driven to apply pressure to the abdomen. During the pressing process, the pressure sensor detects the pressing force in real time, and the control mainboard transmits the real-time detection result to the display screen for real-time display. When the front end of the colonoscope successfully passes through the difficult bending section, the control button is pressed to make the output push rod retract, and the pressing disc is separated from the surface of the abdomen. The auxiliary pressing device for colonoscopy does not need the endoscope nurse or the assistant to continuously press the abdomen of the patient by hand when the colonoscope encounters difficulties during insertion, effectively reducing the work load of the medical staff and the risk of occupational injury.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an auxiliary pressurization device for colonoscopy. Background Technology

[0002] In recent years, the incidence of colorectal diseases has been increasing globally. As an important tool for screening and diagnosing colorectal diseases, electronic colonoscopy has seen a significant increase in clinical demand, leading to a continuous rise in the number of patients undergoing the procedure.

[0003] During a colonoscopy, the operator inserts the colonoscope through the anus, passing it sequentially through the rectum, sigmoid colon, descending colon, transverse colon, ascending colon, and finally to the ileocecal junction. However, due to the multiple physiological bends and significant mobility of the colon, the tip of the colonoscope can easily form a loop in the sigmoid or transverse colon during insertion, leading to obstructed insertion, increased patient pain, or even preventing the examination from being completed. This problem is particularly common among beginners or physicians with limited experience; even experienced physicians may encounter difficulties with colonoscopy in patients with conditions such as abdominal obesity or abdominal adhesions (e.g., a history of abdominal surgery).

[0004] Currently, the main clinical approach involves endoscopic nurses or assistants applying direct pressure to the corresponding area of ​​the patient's abdomen using their palms or fists. The principle is to limit excessive stretching of the intestines by applying external pressure, forcing them to shorten and change their course, thus facilitating the smooth passage of the colonoscope through the curved section. However, manual pressure has several problems: to effectively move the intestines, a large amount of pressure is often required, frequently lasting for several minutes, which is extremely physically demanding for nurses. Especially in cases of thickened abdominal walls or obesity, the pressure applied by a single nurse is often insufficient, requiring two or more nurses to apply pressure in shifts or simultaneously. This method not only increases the workload and occupational injury risk for medical staff, but the accuracy, force, and stability of the pressure application also depend entirely on the operator's personal experience, lacking standardization and controllability.

[0005] Therefore, how to design an auxiliary pressure device for colonoscopy with precise and controllable pressure position, appropriate pressure intensity, and continuous stability is a technical problem that has not yet been solved in the existing technology. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the technical defects of the prior art, which is that manual abdominal compression is physically demanding, and that multiple nurses are needed to take turns or apply pressure to patients with thick abdominal walls or excessive obesity, which increases the workload. Furthermore, the compression position, force, and stability depend entirely on personal experience. The present invention provides an auxiliary pressure device for colonoscopy that provides precise and controllable compression position, appropriate and stable compression force.

[0014] As a preferred embodiment, the guide slider includes: The slider cover has a mounting groove that extends through both ends axially and has an opening at the bottom. The slider cover is fitted onto the arc-shaped guide beam through the bottom opening, and the inner top wall of the mounting groove can slide and contact the top surface of the arc-shaped guide beam. A slider base is fixedly installed at the bottom opening of the mounting groove, thereby movably mounting the guide slider on the arc-shaped guide beam; and / or; A connecting shaft cylinder is fixedly installed at the bottom of the slider base. The connecting shaft cylinder is hollow and open at both ends, and the inner wall of the connecting shaft cylinder is smooth.

[0017] The technical solution provided by this invention has the following advantages: This invention relates to an auxiliary pressurizing device for colonoscopy, comprising an adjusting slide rail, an arched support beam, and a press gun. Two adjusting slide rails are provided, suitable for fixed installation on opposite sides of the bed. Both ends of the arched support beam are movably mounted on the adjusting slide rails. The press gun is movably mounted on the arched support beam with an adjustable pressing angle. The press gun includes a housing, an electric push rod, a pressure sensor, a control board, and a display screen. The housing has a mounting cavity. The electric push rod is installed within the mounting cavity and has an output push rod that is retractable and extends to the outside of the housing, with a pressing plate fixedly mounted on its free end.

[0018] During a colonoscopy, the arched support beam is first adjusted and fixed in place. Then, the position and angle of the compression gun on the arched support beam are adjusted according to the abdominal area requiring compression, aligning it with the predetermined compression point. Once adjusted, the operator presses the control button, extending the output rod of the electric pusher outward and applying pressure to the corresponding area of ​​the patient's abdomen. Because the compression gun can be omnidirectionally adjusted on the arched support beam, the compression direction can be adjusted at any time during the procedure. During compression, a pressure sensor continuously monitors the pressure applied by the compression plate at the front of the electric pusher, converting the pressure value into an electrical signal that is transmitted to the display screen via the control board for the operator to visually read the current pressure value. Once the colonoscope tip has successfully passed through a difficult bend, the operator presses the control button to retract the output rod, causing the compression plate to detach from the abdominal surface. If further obstruction occurs during subsequent insertion, the position and angle of the compression gun can be readjusted according to the new difficult insertion point, and the above compression operation can be repeated until the colonoscope tip successfully reaches the ileocecal junction, completing the examination.

[0019] This invention relates to an auxiliary pressure device for colonoscopy. When difficulties arise during colonoscopy insertion, it eliminates the need for endoscopist nurses or assistants to manually apply continuous pressure to the patient's abdomen, effectively reducing the workload and occupational injury risk for medical staff. The device allows for precise control of the pressure position, pressure intensity, and duration, ensuring a stable and reliable pressure application process. This significantly reduces the physical exertion of medical staff and minimizes additional pain to the patient caused by improper manual pressure. Attached Figure Description

[0041] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0042] This embodiment provides an auxiliary pressurization device for colonoscopy, such as... Figure 1-7As shown in Figure 14, the device includes: an adjusting slide rail 1, an arched support beam 2, and a pressing gun 3; wherein, there are two adjusting slide rails 1, suitable for being fixedly installed on both sides of the bed; both ends of the arched support beam 2 are movably installed on the adjusting slide rail 1; the pressing gun 3 is movably and omnidirectionally adjustable on the arched support beam 2; the pressing gun 3 includes a housing 4, an electric push rod 5, a pressure sensor 6, a control main board 7, and a display screen 8; wherein, the housing 4 has a mounting cavity 41; the electric push rod 5 is installed in the mounting cavity 41 and has an output push rod 51, the output push rod 51 is retractable and can extend to the outside of the housing 4, and a pressing plate 52 is fixedly installed on its free end; the pressure sensor 6 is fixedly installed in the mounting cavity 41 and forms a force transmission connection with the electric push rod 5. The control board 7 is used to detect the pressing pressure value output by the electric push rod 5 in real time and convert the pressing pressure value into an electrical signal for output. The control board 7 is fixedly installed in the mounting cavity 41 and electrically connected to the electric push rod 5 and the pressure sensor 6. It is used to receive the pressing pressure value electrical signal output by the pressure sensor 6 and output the pressing pressure value electrical signal for output. The control board 7 is provided with a control button 71, which is used to control the output push rod 51 of the electric push rod 5 to extend outward or retract inward. The display screen 8 is fixedly installed in the mounting cavity 41 and electrically connected to the control board 7. It is used to receive the pressing pressure value electrical signal output by the control board 7 and display the pressing pressure value output by the pressing plate 52 in real time.

[0043] When performing a colonoscopy on a patient, the arched support beam 2 is first adjusted to the appropriate position and fixed. Then, according to the actual abdominal area to be pressed, the position and angle of the compression gun 3 on the arched support beam 2 are adjusted so that it is aligned with the predetermined compression position. After adjustment, the operator presses the control button 71, which drives the output push rod 51 of the electric push rod 5 to extend outward, driving the compression plate 52 to apply pressure to the corresponding area of ​​the patient's abdomen. Since the compression gun 3 can be omnidirectionally adjusted on the arched support beam 2, the compression direction can be adjusted at any time during the compression process. During the compression process, the pressure sensor 6 detects the external compression force of the compression plate 52 at the front end of the electric push rod 5 in real time, and converts the pressure value into an electrical signal, which is transmitted to the display screen 8 via the control motherboard 7, allowing the operator to intuitively read the current compression pressure value. Once the colonoscope tip has successfully passed through the difficult bend, the operator presses control button 71 to retract the output push rod 51, causing the pressure plate 52 to detach from the abdominal surface. If the loop is obstructed again during subsequent insertion, the position and angle of the pressure gun 3 can be readjusted according to the new difficult insertion location, and the above pressing operation can be repeated until the colonoscope tip successfully reaches the ileocecal junction to complete the examination.

[0044] This embodiment describes an auxiliary pressure device for colonoscopy. When difficulties arise during colonoscopy insertion, it eliminates the need for endoscopist nurses or assistants to manually apply continuous pressure to the patient's abdomen, effectively reducing the workload and occupational injury risk for medical staff. The device allows for precise control of the pressure location, pressure level, and duration, ensuring a stable and reliable pressure application process. This significantly reduces the physical exertion of medical staff and minimizes additional pain to the patient caused by improper manual pressure.

[0045] The electric actuator used in this embodiment is model HB-DJ808, which can be purchased from Wuxi Hongba Electromechanical Co., Ltd.; the pressure sensor used in this embodiment is model C835 miniature sensor, brand: Tianjin Lijing, which can be purchased from the Tianjin Lijing brand store.

[0046] like Figure 15 As shown, the specific control logic of the auxiliary pressurization device used in this embodiment for colonoscopy is as follows: the control motherboard initializes and detects whether there is a control command input. After receiving the control command, the control motherboard controls the display screen and alarm according to the received control command.

[0047] like Figure 9 As shown, the system also includes an alarm 81, which is mounted on the control mainboard 7. When the electrical signal of the pressing pressure value received by the control mainboard 7 exceeds a preset threshold range, it sends a control command to the alarm 81 to sound an alarm and controls the electric push rod 5 to stop outputting pressure. The preset range of the pressing pressure of the electric push rod 5 is 0-120 mmHg. If the real-time pressure value detected by the pressure sensor exceeds 120 mmHg, the control mainboard 7 controls the alarm 81 to sound an alarm and simultaneously controls the electric push rod 5 to stop outputting pressure.

[0048] like Figure 8 As shown, the mounting cavity 41 of the housing 4 includes a push rod mounting cavity 47 and a sensor mounting cavity 48 formed directly above the push rod mounting cavity 47 and communicating with the push rod mounting cavity 47; the electric push rod 5 is movably mounted in the push rod mounting cavity 47; the pressure sensor 6 is fixedly mounted in the sensor mounting cavity 48, with its bottom end extending into the push rod mounting cavity 47 and abutting against the top end of the electric push rod 5, thus forming a downward abutment limit on the electric push rod 5; when the output push rod 51 of the electric push rod 5 drives the pressing plate 52 to press the patient's abdomen, under the action of the reaction force, the electric push rod 5 pushes the pressure sensor 6 upward, thereby causing the pressure sensor 6 to detect the pressing pressure value output by the electric push rod 5.

[0049] It also includes a power cord 82, which is electrically connected to the control motherboard 7 and is suitable for connecting to an external power source to supply power to the control motherboard 7.

[0050] The control button 71 includes an up button 72 and a down button 73; the up button 72 is used to control the output push rod 51 of the electric push rod 5 to retract upwards; the down button 73 is used to control the output push rod 51 of the electric push rod 5 to extend downwards; the housing 4 includes a left housing 42, a right housing 43, and a top housing 45; wherein, the right housing 43 is fixedly connected to the left housing 42 and has two button through holes 44; the up button 72 and the down button 73 extend from the button through holes 44 to the outside of the right housing 43 respectively; the top housing 45 is fixedly installed on the top of the left housing 42 and the right housing 43 and has an observation window 46; the display screen 8 is vertically opposite to the observation window 46.

[0051] like Figure 9 As shown, the control motherboard 7 includes a receiving module 74, a control module 75, a first output module 76, and a second output module 77. The receiving module 74 receives the pressing pressure value electrical signal from the pressure sensor 6. The control module 75 is electrically connected to the receiving module 74 and receives the electrical signal from the receiving module 74, and outputs corresponding control commands based on the electrical signal. The first output module 76 transmits the control commands output by the control module 75 to the display screen 8. The second output module 77 transmits the control commands output by the control module 75 to the alarm 81.

[0052] like Figure 16 As shown, the receiving module receives the electrical signal output by the pressure sensor and transmits it to the control motherboard. The control motherboard transmits the control command to the display screen through the first output module, and controls the display screen to display the current pressure value in real time. At the same time, the control module continuously judges whether the pressure value exceeds the preset threshold. When the pressure value exceeds the upper limit, the control command is transmitted to the alarm through the second output module, and the alarm is triggered.

[0053] like Figure 10-11 As shown, the press gun 3 is movably and omnidirectionally adjustable on the arched support beam 2 via a movable mounting structure; the movable mounting structure includes an arc-shaped guide beam 21, a guide slider 22, and a spherical bearing 23; wherein, there are two arc-shaped guide beams 21, each formed on the arched support beam 2; there are two guide sliders 22, each movably mounted on the arc-shaped guide beam 21; the spherical bearing 23 includes a bearing seat 24 and a ball bearing 25 rotatably mounted in the bearing seat 24; both ends of the bearing seat 24 are fixedly connected to the guide sliders 22 on both sides, and the lower end of the housing 4 of the mounting gun 3 is provided with a threaded shaft, which is screwed to the threaded mounting hole 26 in the middle of the ball bearing 25.

[0054] The guide slider 22 includes a slider cover 9 and a slider base 92; wherein, the slider cover 9 has a mounting groove 91, which extends through both ends axially and has an opening at the bottom; the slider cover 9 is sleeved on the arc-shaped guide beam 21 through the bottom opening, and the inner top wall of the mounting groove 91 can slide and contact the top surface of the arc-shaped guide beam 21; the slider base 92 is fixedly installed at the bottom opening position of the mounting groove 91, thereby movably installing the guide slider 22 on the arc-shaped guide beam 21; after the guide slider 22 is installed on the arc-shaped guide beam 21, there is a certain gap between the slider base 92 and the arc-shaped guide beam 21, thereby movably installing the guide slider 22 on the arc-shaped guide beam 21. A connecting shaft cylinder 93 is fixedly installed at the bottom of the slider base 92. The connecting shaft cylinder 93 is hollow and open at both ends, and the inner wall of the connecting shaft cylinder 93 is smooth. Threaded connecting shafts 94 are fixedly installed at both ends of the bearing seat 24. After the threaded connecting shafts 94 pass through the connecting shaft cylinder 93, they are screwed to the free end of the threaded connecting shafts 94 with connecting nuts 95, thereby fixing the spherical bearing 23 and the guide slider 22 together.

[0055] like Figure 10 As shown, the bottom surface of the arc-shaped guide beam 21 is provided with a plurality of first meshing teeth 96; the top surface of the slider base 92 is provided with a plurality of second meshing teeth 97; when the pressing gun 3 presses down on the patient's abdomen, under the action of the reaction force, the second meshing teeth 97 engage with the first meshing teeth 96, thereby locking the guide slider 22 and preventing the mounting gun 3 from moving.

[0056] like Figure 12-13 As shown, the adjusting slide rail 1 has a limiting guide groove 11 formed on it; the two ends of the arched support beam 2 are respectively fixedly provided with limiting guide sliders 12; the limiting guide sliders 12 are matched and installed with the limiting guide groove 11, and can move back and forth along the limiting guide groove 11, so as to movably install the arched support beam 2 on the adjusting slide rail 1; the limiting guide slider 12 has a threaded limiting hole 13; it also includes a limiting bolt 14, after the limiting bolt 14 is screwed into the threaded limiting hole 13, the free end of the limiting bolt 14 presses against the adjusting slide rail 1 to limit and fix the limiting guide slider 12.

[0057] The auxiliary pressure device used in this embodiment for colonoscopy is used as follows: First, loosen the limiting bolt 14 outwards to release the lock on the limiting guide slider 12. Then, move the limiting guide slider 12 along the limiting guide groove 11, moving the arched support beam 2 to the appropriate position. Next, tighten the limiting bolt 14 inwards to fix the arched support beam 2. Based on the abdominal area requiring pressure, move the guide slider 22 along the arc-shaped guide beam 21, moving the pressure gun 3 to the appropriate position. Then, rotate the pressure gun 3, using the rotation of the ball bearing 25 within the bearing seat 24 to adjust the tilt angle of the pressure gun 3, aligning the pressure plate 52 with the preset pressure area.

[0058] After adjustment, the operator presses the down button 73, and the control board 7 controls the output push rod 51 of the electric push rod 5 to extend outward, driving the pressing plate 52 to apply pressure to the corresponding area of ​​the patient's abdomen. Under the action of the reaction force, the second meshing tooth 97 of the slider base 92 engages with the first meshing tooth 96 of the arc-shaped guide beam 21, thereby limiting and fixing the mounting gun 3. During this process, the pressure sensor 6 detects the pressing force of the pressing plate 52 at the front end of the electric push rod 5 in real time and converts the pressure value into an electrical signal and transmits it to the receiving module 74. After receiving the electrical signal, the receiving module 74 transmits it to the control module 75. The control module 75 transmits the control command to the display screen 8 through the first output module 76, and controls the display screen 8 to display the current pressure value in real time, so that the operator can intuitively read the current pressing pressure value. At the same time, the control module 75 continuously judges whether the pressure value exceeds the preset threshold. When the pressure value exceeds 1200 mmHg, the control command is transmitted to the alarm 81 through the second output module 77, controlling the alarm 81 to sound an alarm and simultaneously controlling the electric push rod 5 to stop outputting pressure.

[0059] Once the colonoscope tip has successfully passed the difficult bend, the operator presses the up button 72, which controls the main board 7 to retract the output push rod 51, causing the pressure plate 52 to detach from the abdominal surface. If the loop is obstructed again during subsequent insertion, the position and angle of the pressure gun 3 can be readjusted according to the new difficult insertion location, and the above pressing operation can be repeated until the colonoscope tip successfully reaches the ileocecal junction, completing the examination.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
