Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a device for assisting abdominal compression during colonoscopy. Background Art

[0002] Colonoscopy is an important means of diagnosing intestinal diseases. Colonoscopy can observe the internal structure of the intestines, and the development of certain lesions can also be known through this examination. It is also a relatively effective method for intestinal screening examinations. During colonoscopy, a colonoscope is needed to enter the patient's intestines from the anus. The intestines have many bends. When the colonoscope passes through some bends, medical staff often need to press the patient's abdomen from different angles to change the internal intestinal bends and help the colonoscope pass.

[0003] When the doctor presses the patient's abdomen while inserting a colonoscope, he needs to bend over and get closer to the patient to make it easier for his arms to exert force. Bending over for a long time will cause the doctor's lower back pain or even strain.

[0004] The Chinese patent application, CN220778641U, titled "A Colonoscopy-Assisted Abdominal Compression Device," includes a compression assembly and a fixed base. The compression assembly includes a compression rod and an extension handle, which is rotatably connected to the upper end of the compression rod. In this application, medical personnel use the extension handle to drive the compression rod to compress the patient's abdomen without having to bend over for long periods of time, effectively avoiding the problem of lumbar strain caused by prolonged compression of the patient's abdomen.

[0005] Regarding the above technical solution, although the handle design reduces the fatigue of medical staff, due to the use of a wearable structure, during the pressing process, due to the lack of effective positioning and anti-displacement mechanism, it is easy to roll on the patient's body surface, resulting in the displacement of the pressure position and affecting the pressing effect; to maintain the stability of the device, the operator needs additional support, which increases the complexity of the operation and the manpower burden. In addition, when the patient changes position (such as turning over), the device needs to be disassembled and put on again, which not only prolongs the examination time and reduces the efficiency of diagnosis and treatment, but also has poor adaptability to different body shapes and positions, and its use scenarios are limited, making it difficult to meet the diverse clinical needs. Summary of the Invention

[0006] In view of this, the present application provides a colonoscopy auxiliary abdominal compression device, which is mainly used to solve the problem that the colonoscopy auxiliary abdominal compression device is easily displaced and requires support when used, and needs to be re-donned and adjusted when the body position changes, resulting in poor stability and inconvenience in operation.

[0007] In order to solve the above technical problems, the present application provides an auxiliary abdominal compression device for colonoscopy, comprising two groups of symmetrically arranged bow frames, a cross arm is provided between the two groups of bow frames, a clamping member for fixing to the bed body is provided at the bottom of the bow frame, a cross bar is slidingly arranged between the two groups of bow frames, a slider is provided on the outer side of the cross bar, a bottom plate is provided at the bottom of one side of the slider, a fixed cylinder is provided in the middle of the bottom plate, a pressure rod is provided on the inner movable sleeve of the fixed cylinder, a pressure plate is provided at the bottom of the pressure rod, and an angle adjustment component is provided on the slider for adjusting the inclination angle of the bottom plate; a support plate is provided on one side of the bottom plate, a torsion plate is hinged on the top of the support plate, a push rod is provided at one end of the torsion plate, and a movable frame is hinged on the other end of the torsion plate, and the movable frame is hinged to the top end of the pressure rod.

[0008] By adopting the above technical solution, the device adopts two sets of symmetrically arranged bow frames, the bottom of which is equipped with a clamping piece fixed to the bed. The clamping piece can firmly engage the edge of the bed, so that the entire device can be stably mounted above the patient's examination bed. Compared with the wearable structure, it avoids the risk of rolling and shifting on the patient's abdomen, and provides a solid foundation for subsequent precise pressing. By setting a position-adjustable pressure plate, it can cover different positions of the patient's abdomen and meet the need to apply pressure to various parts of the intestine during colonoscopy. When the medical staff presses down the push rod, according to the principle of lever arm, a larger downward pressure can be generated at the pressure rod with a smaller force, which effectively reduces operator fatigue and ensures that the pressing force is stable and controllable. Compared with the existing auxiliary abdominal compression device, it has better stability and ease of operation, which is conducive to promotion and use.

[0009] Optionally, the bottom plate is provided with an arc track, and the bottom of the support plate is sleeved on the outside of the arc track and can slide along the arc track.

[0010] By adopting the above technical solution, the pressing structure can be adjusted according to the position of the medical staff during actual use, reducing its limitations in use, and allowing the medical staff to apply force in the most comfortable posture, greatly improving the practicality of the device.

[0011] Optionally, the angle adjustment assembly includes a movable cavity, which is arranged inside the slider, and a clamping block is provided inside the movable cavity. A pull ring movably connected to the slider is provided on the top of the clamping block, and a first spring is fixedly connected between the pull ring and the slider. A plurality of clamping grooves distributed along the axial direction are provided on the outer peripheral surface of the cross bar, and the clamping block is adapted to the clamping slot.

[0012] By adopting the above technical solution, the angle of the pressing structure can be adjusted according to the usage situation, providing accurate and stable pressing force, and promoting the smooth progress of colonoscopy.

[0013] Optionally, the facing surfaces of the bow-shaped frame are provided with sliding grooves, and both ends of the cross bar are provided with connecting plates adapted to the sliding grooves, and rollers are provided on the connecting plates.

[0014] By adopting the above technical solution, the sliding friction between the cross bar and the bow frame is converted into rolling friction by using the roller, thereby reducing the adjustment resistance of the pressing structure and making the operation more labor-saving.

[0015] Optionally, a swivel is rotatably connected to the outer side of the bottom of the fixed cylinder, a connecting frame is fixedly connected to the pressure rod, a second spring is fixedly connected between the swivel and the connecting frame, and the connecting frame is sleeved on the swivel.

[0016] By adopting the above technical solution, when the push rod is released, the second spring can quickly drive the pressure rod to reset upward by virtue of the restoring force generated by its own elastic deformation, thereby preparing for the next pressing operation and improving operational efficiency.

[0017] Optionally, a movable groove is provided inside the bow-shaped frame, a movable frame is provided below the bow-shaped frame, the top of the movable frame is fixedly connected with an insertion rod adapted to the movable groove, the middle part of the cross arm is threadedly connected with a second screw, the top of the second screw is fixedly connected with a second turntable, and the second screw is rotatably connected to the movable frame.

[0018] By adopting the above technical solution, the second turntable is rotated, and the second turntable drives the second screw to move the movable frame up or down, so that the height of the bow frame of the device from the bed can be adjusted according to the patient's body shape, reducing its usage limitations.

[0019] Optionally, the clamping member includes a fixed plate fixedly connected to the movable frame, a movable plate is arranged below the fixed plate, a first screw is threadedly connected to the fixed plate, the top of the first screw is fixedly connected to the first turntable, the bottom end of the first screw is rotatably connected to the movable plate, and two symmetrically distributed side plates are arranged at the bottom of the fixed plate, and the side plates pass through the movable plate.

[0020] Optionally, both the lower surface of the fixed plate and the upper surface of the movable plate are provided with anti-slip pads.

[0021] By adopting the above technical solution and providing an anti-slip pad on the contact surface of the clamping part, the friction between the device and the bed can be enhanced, preventing the device from shifting when pressing, and ensuring the accuracy of pressure; at the same time, with its own elasticity and softness, it can also buffer the clamping pressure and avoid damage to the bed.

[0022] Optionally, a handle is sleeved on the outer side of one end of the push rod away from the torsion plate.

[0023] By adopting the above technical solution, the sleeve handle can increase the comfort of medical staff in holding the push rod and has a good anti-slip effect.

[0024] Optionally, the pressure plate and the pressure rod are connected using a detachable structure.

[0025] By adopting the above technical solution, the pressure plate and pressure rod adopt a detachable structure, which is convenient for independent cleaning and disinfection after disassembly, reducing the risk of cross infection; different specifications of pressure plates can be replaced as needed to adapt to the patient's body shape and examination needs; at the same time, the maintenance process is simplified, maintenance costs are reduced, and the service life of the equipment is extended.

[0026] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0027] 1. The clamping piece at the bottom of the bow frame secures it to the bed. Compared to traditional wearable devices, this effectively avoids the risk of rolling or shifting on the patient's abdomen, ensuring the device remains stable and stable during compression, providing reliable support for precise pressure application. Furthermore, the position and angle of the compression mechanism can be flexibly adjusted according to user needs, making operation simple and quick, thereby improving diagnostic and treatment efficiency.

[0028] 2. The pressing structure designed with the lever principle allows medical staff to generate a large downward pressure at the pressing rod with a small force by pressing down the push rod. This not only reduces the fatigue caused by long-term operation, but also ensures that the pressing force is stable and controllable, effectively improving the comfort and accuracy of the abdominal pressing operation during colonoscopy.

[0029] 3. Through the coordination between the arc track and the pressing structure, the angle of the pressing structure can be flexibly adjusted according to the position of the medical staff, reducing the limitations of its use. It also allows medical staff to apply force in the most comfortable posture, greatly improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application Figure 1-Figure 7 , clearly and completely describes the technical solutions of the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the described embodiments of this application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0039] Reference Figure 1 、 Figure 2 and Figure 5 This embodiment provides an auxiliary abdominal compression device for colonoscopy, comprising a frame, a position adjustment assembly, an angle adjustment assembly, a pressing assembly, and a clamping member. The frame comprises two symmetrically arranged arched frames 1, with a cross arm 8 fixedly connected between the two arched frames 1. The displacement adjustment assembly is disposed above the frame and can adjust the position of the pressing assembly according to usage requirements; the angle adjustment assembly is used to adjust the angle of the pressing assembly; and the clamping member is disposed at the bottom of the frame and is used to secure the frame to the bed.

[0040] Among them, reference Figure 1 The position adjustment assembly includes a crossbar 2, a connecting plate 21, a chute 11, and a slider 3. The chute 11 is provided on the facing surfaces of the two sets of arch frames 1. The connecting plates 21 are fixedly mounted at both ends of the crossbar 2. The connecting plates 21 fit in the chute 11. The crossbar 2 is slidably connected between the two sets of arch frames 1 via the connecting plates 21 and the chute 11. The slider 3 is slidably sleeved on the outside of the crossbar 2.

[0041] The pressing assembly is arranged on the slider 3. When the cross bar 2 moves along the slide groove 11, the pressing assembly can move forward and backward; when the slider 3 moves along the cross bar 2, the pressing assembly can move left and right to cover different pressure areas, meeting the pressure requirements of various parts of the intestine during colonoscopy.

[0042] Among them, reference Figure 2 、 Figure 3 and Figure 4 The angle adjustment assembly includes an active cavity 31, which is arranged inside the slider 3. A clamping block 32 is provided inside the active cavity 31. A pull ring 33 movably connected to the slider 3 is provided on the top of the clamping block 32. A first spring 34 is fixedly connected between the pull ring 33 and the slider 3. A plurality of clamping grooves 23 distributed along its axial direction are provided on the outer peripheral surface of the cross bar 2, and the clamping block 32 is adapted to the clamping groove 23.

[0043] When the tilt angle of the pressing assembly needs to be adjusted, the medical staff pulls up the pull ring 33 to drive the block 32 out of the slot 23, and the first spring 34 is compressed. At this time, the slider 3 is rotated to adjust the angle of the pressing assembly. After the adjustment is completed, the pull ring 33 is released. Under the action of the first spring 34, the block 32 is re-engaged in the corresponding slot 23, so that the angle of the slider 3 is fixed. The angle of the pressing assembly can be adjusted, and the operation is simple and convenient.

[0044] Among them, reference Figure 1 and Figure 2 The pressing assembly includes a base plate 4, a fixed cylinder 41, a pressure rod 42, and a pressure plate 43. The fixed cylinder 41 is fixedly connected to the middle of the base plate 4, the pressure rod 42 is movably mounted inside the fixed cylinder 41, and the pressure plate 43 is fixedly mounted on the bottom end of the pressure rod 42. The base plate 4 is fixedly connected to the bottom of one side of the slider 3. A support plate 5 is set on one side of the base plate 4. The top of the support plate 5 is hinged to a torsion plate 51. A push rod 53 is installed at one end of the torsion plate 51. A handle 54 is mounted on the outer side of the push rod 53 away from the torsion plate 51 to increase the comfort of the medical staff's grip and prevent slipping. The other end of the torsion plate 51 is hinged to a movable frame 52, which is hinged to the top of the pressure rod 42 to form a lever transmission structure.

[0045] When the medical staff pushes up the push rod 53, the push rod 53 drives the torsion plate 51 to move the movable frame 52 downward, and the movable frame 52 drives the pressure rod 42 to move the pressure plate 43 downward. According to the lever arm principle, a large downward pressure is generated at the pressure plate 43, achieving effortless pressing while ensuring that the pressing force is stable and controllable, thereby improving the comfort of the abdominal pressing operation during colonoscopy.

[0046] In addition, refer to Figure 1 and Figure 5 The clamping member includes a fixed plate 12, a movable plate 13, a first screw 14, a first rotary disc 15, and a side plate 16. Specifically, the fixed plate 12 is disposed below the arch frame 1, and the movable plate 13 is disposed below the fixed plate 12. The side plate 16 is vertically fixed to the bottom of the fixed plate 12 and passes through the movable plate 13, acting as a position limiting guide for the movable plate 13. The first screw 14 is threadedly connected to the fixed plate 12, with its top end fixedly connected to the first rotary disc 15 and its bottom end rotatably connected to the movable plate 13.

[0047] During use, medical personnel rotate the first turntable 15, driving the first screw 14 to rotate, driving the movable plate 13 toward the fixed plate 12, thereby firmly engaging the clamping member with the edge of the bed. Furthermore, anti-slip pads 17 are provided on the lower surface of the fixed plate 12 and the upper surface of the movable plate 13. These pads effectively enhance friction between the device and the bed, preventing displacement during application. The elasticity and softness of the anti-slip pads 17 also cushion the clamping pressure, preventing damage to the bed.

[0048] Reference Figure 1 and Figure 2 The bottom plate 4 is provided with an arc track 44, and the bottom of the support plate 5 is sleeved on the outside of the arc track 44 and can slide along it.

[0049] The pressure rod 42 is sleeved within the fixed cylinder 41 and can rotate with the support plate 5. When the support plate 5 moves along the curved track 44, it does not affect the use of the pressure plate 43. This allows medical staff to flexibly adjust the position of the push rod 53 according to their own standing position, applying force in the most comfortable posture and reducing usage limitations.

[0050] Reference Figure 6 A roller 22 is rotatably connected to the connecting plate 21 .

[0051] The cross bar 2 can slide smoothly in the slide groove 11 through the roller 22, converting the sliding friction into rolling friction, reducing the resistance when the cross bar 2 is adjusted, and making the operation more labor-saving.

[0052] Reference Figure 1 and Figure 2 The outer side of the bottom of the fixed cylinder 41 is rotatably connected to a swivel 7, the pressure rod 42 is fixedly connected to a connecting frame 71, a second spring 72 is fixedly connected between the swivel 7 and the connecting frame 71, and the connecting frame 71 is sleeved on the swivel 7.

[0053] When pressing the patient's abdomen, the pressure rod 42 drives the connecting frame 71 to move downward. At this time, the connecting frame 71 and the rotating ring 7 make relative movement, and the second spring 72 is stretched. After the pressing is completed, the medical staff unloads the force. Under the action of the second spring 72, the connecting frame 71 drives the pressure rod 42 to make the pressure plate 43 move up quickly and reset, preparing for the next pressing operation, effectively improving the operating efficiency.

[0054] Among them, reference Figure 1 and Figure 7 A movable groove 18 is provided inside the bow-shaped frame 1, and a movable frame 6 is provided below the bow-shaped frame 1. The top of the movable frame 6 is fixedly connected with an insertion rod 63 adapted to the movable groove 18. The middle part of the cross arm 8 is threadedly connected with a second screw 61, and the top of the second screw 61 is fixedly connected with a second turntable 62. The second screw 61 is rotatably connected to the movable frame 6.

[0055] Medical staff rotate the second turntable 62 to drive the second screw 61 to rotate, so that the insertion rod 63 on the movable frame 6 moves up or down along the movable groove 18, thereby adjusting the height of the bow frame 1 from the bed to adapt to patients of different body sizes and reduce the limitations of the device.

[0056] Reference Figure 1 and Figure 2 The pressure plate 43 and the pressure rod 42 are connected in a detachable structure, such as by threaded connection, snap connection, etc. (the specific connection method can be selected according to the actual design).

[0057] After the examination is completed, the pressure plate 43 can be quickly removed for independent deep cleaning and disinfection to avoid the risk of cross infection; at the same time, the pressure plate 43 of different sizes and materials can be replaced according to the different patient body shapes and examination requirements to optimize the pressing comfort and pressure effect; in addition, when the pressure plate 43 is worn or damaged, only the pressure plate 43 needs to be replaced, which simplifies the maintenance process, reduces maintenance costs, and extends the service life of the equipment.

[0058] The implementation principle of the enteroscopic auxiliary abdominal compression device in the embodiment of the present application is as follows:

[0059] During use, medical personnel rotate the first turntable 15 on the clamp, driving the first screw 14 to rotate, driving the movable plate 13 toward the fixed plate 12, firmly engaging the clamp with the edge of the bed. Anti-slip pads 17 on the surfaces of the fixed plate 12 and movable plate 13 enhance friction with the bed, preventing displacement during compression. They also buffer the clamping pressure, protecting the bed and providing a stable foundation for subsequent operations.

[0060] When adjusting the position of the pressing assembly, the cross bar 2 slides in the slide groove 11 on the opposite side of the bow frame 1 through the roller 22, so that the pressing assembly moves forward and backward; when the slider 3 moves along the cross bar 2, the pressing assembly can move left and right to cover different pressure areas, meeting the pressure requirements of various parts of the intestine during colonoscopy.

[0061] When the tilt angle of the pressing assembly needs to be adjusted, the medical staff pulls up the pull ring 33, driving the block 32 to disengage from the slot 23 on the cross bar 2, and the first spring 34 is compressed. At this time, the slider 3 can be rotated; after adjusting to the appropriate angle, the pull ring 33 is released, and under the action of the first spring 34, the block 32 is re-engaged in the corresponding slot 23, so that the angle of the slider 3 is fixed, thereby realizing the angle adjustment of the pressing assembly.

[0062] During compression, when the medical staff pushes the push rod 53 upward, the push rod 53 drives the torsion plate 51 to move the movable frame 52 downward, and the movable frame 52 drives the pressure rod 42 to move the pressure plate 43 downward. According to the lever arm principle, a large downward force is generated on the pressure plate 43, achieving effortless compression. The lever transmission structure formed by the torsion plate 51, the movable frame 52, and the pressure rod 42 uses the lever arm principle to generate a large downward force on the pressure plate 43 with a small force, achieving effortless compression while ensuring a stable and controllable pressure, helping the colonoscope to pass smoothly through the bends in the intestine.

[0063] After the compression is complete, the medical staff releases the force, allowing the rotating ring 7, connecting frame 71, and second spring 72 on the outside of the bottom of the fixed cylinder 41 to take effect. Under the elastic restoring force of the second spring 72, the connecting frame 71 drives the compression rod 42 and the pressure plate 43 to quickly move upward and reset, preparing for the next compression. In addition, if the patient's body size varies, the medical staff can rotate the second rotating disk 62, driving the second screw 61 to rotate, causing the insertion rod 63 on the movable frame 6 to move up or down along the movable slot 18 in the bow frame 1, thereby adjusting the height of the bow frame 1 from the bed to suit different patient needs.

[0064] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0065] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
