Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and in particular to a quantitative pressure-assisted colonoscopy abdominal binder. Background Technology

[0002] Colonoscopy is one of the most direct and effective methods for diagnosing and treating intestinal diseases. However, in clinical practice, due to the long, tortuous, and free-floating anatomical features of the human colon, the endoscope is prone to looping when passing through the sigmoid colon, hepatic flexure, and splenic flexure. To overcome this resistance and assist in insertion, clinicians typically rely on manual abdominal pressure applied by the patient, using a combination of pushing, pressing, and kneading techniques with their fingers or palms to help unloop and fix the intestinal tract. However, this traditional manual assistance method is highly dependent on the assistant's personal experience and feel, and during prolonged examinations, it is difficult to maintain a constant pressure and frequency, easily leading to assistant fatigue. Furthermore, while some abdominal binders with inflatable cuffs have become available, these devices mostly provide only static surface pressure and lack dynamic mechanical mechanisms, failing to simulate the delicate palpation movements of the human hand, resulting in limited assistance.

[0003] However, currently, most traditional abdominal binders use static pressure and lack a mechanical transmission mechanism that can simulate the combined actions of "pushing and loosening the abdominal loops" and "fixed-point pressing" by human hands. They cannot assist the endoscope through complex intestinal bends through dynamic movement. Furthermore, simple rigid mechanical pressing or large-area airbag compression cannot replicate the gentle touch of human hand pads pushing and pressing, which can easily cause discomfort from skin traction or soft tissue damage to patients, resulting in poor patient tolerance. At the same time, traditional manual assistance cannot quantify the pressure and movement frequency, and existing simple mechanical devices often lack quantitative adjustment and visual feedback mechanisms, making it difficult to accurately adapt the assistance force according to the patient's body shape and tolerance.

[0004] Therefore, there is an urgent need for a colonoscopy insertion aid abdominal binder that can simulate the movement trajectory of a human hand, has a flexible feel, and is quantitatively adjustable, in order to solve the above problems. Summary of the Invention

[0005] This invention provides a quantitative pressure-assisted colonoscopy abdominal binder, specifically comprising: The main body has multiple strap assemblies on one side, and at least three placement bags arranged in a triangular pattern on its upper surface, corresponding to the patient's upper abdomen, left abdomen, and right abdomen, respectively. A pressure assembly is installed inside each of the three placement bags, consisting of an installation box and a pressure component. Limiting grooves are formed on the left and right inner walls of the installation box, and a drive unit is provided on the outer wall of the installation box. The drive unit has a drive shaft passing through the outer wall of the installation box and moving towards the interior of the installation box, and a fixed connection is made to the drive shaft. The second connecting rod forms a crank mechanism; a limiting rod is rotatably connected to the middle of the pressurizing component, and one end of the limiting rod is rotatably connected to the pressurizing component, while the other end is engaged in the limiting slide groove and slides along the limiting slide groove; a first connecting rod is rotatably connected to one end of the pressurizing component, and a second connecting rod is rotatably connected to the end of the first connecting rod away from the pressurizing component; when the drive unit starts, it drives the pressurizing component to move in an asymmetrical curve through the second connecting rod and the first connecting rod. The lowest point of the pressurizing component is set as β, and the trajectory of point β is a teardrop-like curve with one side stretching and the other side contracting.

[0006] Preferably, the pressurizing component is wrapped with an airbag on its outer side; the diameter of the end of the airbag at point β is larger than the diameter of the other end of the airbag.

[0007] Preferably, one of the mounting boxes is equipped with a control unit, and the control unit has an interactive interface; the control unit is electrically connected to the drive unit and is used to control the start and stop of the drive unit and adjust the power output of the drive unit.

[0008] Preferably, the control unit has a built-in Bluetooth module, which can be used to pair with external remote control devices.

[0009] Preferably, the strap assembly includes a first strap, a second strap, and a third strap; the first strap and the second strap are respectively located at the uppermost and lowermost ends of the main body, and the first strap and the second strap extend from the end of the main body located on the back side of the patient and are fixed to the end of the main body located on the front side of the patient; the third strap is located in the middle of the main body, and the third strap extends from the end of the main body located on the front side of the patient, and after wrapping around an opening at the end of the main body located on the back side of the patient, it is fixed to the third strap itself.

[0010] Preferably, it also includes connecting pipes; the inflation pipes of at least three of the airbags are connected in parallel via multi-port connectors; the parallel inflation pipes of at least three of the airbags and the power supply pipe of the drive unit are integrated into a connecting pipe, and are further separated into an air source pipe and a power supply pipe at the end away from the main body; the power supply pipe is connected to an external power source, and the air source pipe is connected to an external gas source.

[0011] Preferably, a pressure gauge is installed on the air source pipeline to detect the airbag pressure.

[0012] Preferably, the gas source can be a manual compression type or an air compressor.

[0013] Preferably, the strap assembly can be fixed by using buckles or Velcro.

[0014] Preferably, the pressurizing component is detachably connected to the main body, and the pressurizing component can be installed according to the pressurization requirements.

[0015] Beneficial effects 1. In this invention, the driving unit, in conjunction with the multi-link and limiting slide mechanism, drives point β on the pressure component to generate a unique asymmetric teardrop-like curve trajectory. This motion trajectory replicates the composite bionic action of medical staff's fingers "pushing, pressing, and kneading": the unilateral stretching phase of the trajectory simulates the action of the fingers pushing the abdomen and unblocking loops, effectively pushing the intestinal wall to assist the endoscope in passing through the curved parts by utilizing the extended stroke; the contraction phase of the trajectory simulates the fixed-point pressing action, used to fix the intestinal tube and prevent the endoscope from retracting; this structure significantly improves the smoothness of colonoscope insertion, effectively reduces intestinal loop formation, and greatly reduces the difficulty of passing through curved intestinal segments by simply relying on the rotation of the endoscope. 2. In this invention, an asymmetric conical airbag is wrapped around the outside of the pressure component. Combined with the movement trajectory of point β, the fluidity of the gas softens the mechanical feel, achieving gentle sliding friction. This not only realistically simulates the feel of a human hand pushing against the abdomen, preventing skin traction damage, but also significantly improves patient comfort through the cushioning effect of the airbag. In addition, with the control unit and pressure gauge, quantitative and visual adjustment of the pressure and movement parameters is achieved. Medical staff can flexibly adjust according to the patient's body shape and tolerance, ensuring the effectiveness of assisted endoscopy while avoiding tissue damage caused by excessive pressure, thus possessing extremely high clinical practical value.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0030] In this document, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] Example: Please refer to Figures 1 to 9 : This invention proposes a quantitative pressure-assisted colonoscopy abdominal binder, comprising: The main body 101 has multiple strap assemblies on one side. At least three placement bags 105 are arranged in a triangular pattern on the upper surface of the main body 101, corresponding to the patient's upper abdomen, left abdomen, and right abdomen, respectively. A pressure assembly is installed inside each of the three placement bags 105, consisting of an installation box 201 and a pressure component 301. Limiting grooves 2011 are respectively formed on the left and right inner walls of the installation box 201, and a drive unit 202 is provided on the outer wall of the installation box 201. The drive unit 202 has a drive shaft 2021 that passes through the outer wall of the installation box 201 and faces into the installation box 201, and a second connecting rod 304 is fixedly connected to the drive shaft 2021 to form a crank mechanism. The middle part of the pressure member 301 is rotatably connected to the limiting rod 302, and one end of the limiting rod 302 is rotatably connected to the pressure member 301, while the other end is engaged in the limiting slide groove 2011 and slides along the limiting slide groove 2011; one end of the pressure member 301 is rotatably connected to the first connecting rod 303, and the end of the first connecting rod 303 away from the pressure member 301 is rotatably connected to the second connecting rod 304; when the drive unit 202 is started, the pressure member 301 is driven to move in an asymmetrical curve through the second connecting rod 304 and the first connecting rod 303. The lowest point of the pressure member 301 is set as β, and the movement trajectory of point β is a teardrop-like curve with one side stretching and the other side contracting.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the driving unit 202 drives the multi-link mechanism to generate an asymmetric teardrop-like curve trajectory at point β on the pressure member 301. (Refer to...) Figure 5 and Figure 6 Compared to traditional linear reciprocating motion, this trajectory perfectly simulates the combined "pushing, pressing, and kneading" movements of medical staff's fingers: the unilateral stretching portion of the trajectory corresponds to the finger's pushing and unblocking action, using the extended stroke of the trajectory to push the intestinal wall and assist the endoscope through bends; the contracting portion of the trajectory corresponds to a fixed-point pressing action, used to fix the intestinal tract and prevent the endoscope from retracting. This biomimetic motion trajectory effectively assists in colonoscope insertion, reduces intestinal loop formation, and provides smooth, shock-free movement, significantly improving patient comfort.

[0033] Among them, the outer side of the pressurizing component 301 is wrapped with an airbag 4; the diameter of one end of the airbag 4 located at point β is larger than the diameter of the other end of the airbag 4.

[0034] like Figure 3 and Figure 4 As shown, in this embodiment, by setting an airbag 4 on the outside of the pressurizing member 301, the fluidity of the gas is used to further soften the tactile sensation of the movement at point β, avoiding discomfort caused by rigid contact. In particular, the airbag 4 has an asymmetrical design, which, combined with the asymmetrical movement trajectory of point β, allows the larger end face of the airbag 4 to provide a wider contact area when the point β is "pushed", achieving a soft sliding friction and more realistically simulating the feel of the flesh pad when a human hand pushes the abdomen, preventing skin traction damage.

[0035] One of the mounting boxes 201 is equipped with a control unit 203, which has an interactive interface. The control unit 203 is electrically connected to the drive unit 202 and is used to control the start and stop of the drive unit 202 and adjust the power output of the drive unit 202.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the interactive interface of the control unit 203 can be implemented individually or in combination using a touch screen, buttons, or other structures; the control unit 203 makes the motion trajectory parameters of point β adjustable; by adjusting the power output of the drive unit 202, the motion speed and displacement amplitude of point β on the water droplet-like trajectory can be changed; in actual operation, medical staff can adjust the degree of "stretching" of the trajectory according to the patient's tolerance and the passage of the colonoscope, thereby controlling the force and stroke of the "push" action, realizing the quantitative and personalized adjustment of the bionic pressing action.

[0037] It should be noted that at least three pressurizing components 301 can be individually controlled by the control unit 203. That is, the operator can select one, two or all of the pressurizing components 301 to control them according to their needs through the control unit 203.

[0038] The control unit 203 has a built-in Bluetooth module, which can be paired with external remote control devices.

[0039] In this embodiment, the Bluetooth remote control function allows medical staff to remotely adjust the movement state of point β without touching the abdominal binder when their hands are usually in the clean area during colonoscopy. This ensures that the "pushing and pressing action" simulated by point β can be synchronized with the advance and retreat of the colonoscope in real time, improving the accuracy and convenience of the auxiliary operation, while also avoiding the risk of cross-infection caused by repeated contact with the equipment.

[0040] The strap assembly includes a first strap 102, a second strap 103, and a third strap 104. The first strap 102 and the second strap 103 are respectively placed at the uppermost and lowermost ends of the main body 101, and the first strap 102 and the second strap 103 are led out from the end of the main body 101 on the back side of the patient and fixed to the end of the main body 101 on the front side of the patient. The third strap 104 is placed in the middle of the main body 101, and the third strap 104 is led out from the end of the main body 101 on the front side of the patient, and after wrapping around the opening at the end of the main body 101 on the back side of the patient, it is fixed to the third strap 104 itself.

[0041] like Figure 9 As shown in the above embodiment, the three pressure components protrude from the end face of the main body 101 on the patient's side, affecting the fixation of the abdominal binder. Therefore, a binding arrangement and fixation method is proposed to adapt to the abdominal binder in this invention. The stable three-point fixation structure ensures that when the drive unit 202 is working and point β performs high-frequency or large-amplitude droplet-like trajectory movement, the abdominal binder main body 101 and the internal pressure components can always be in close contact with the patient's abdomen without displacement or loosening, thereby ensuring the effective transmission of the bionic pushing and pressing action and avoiding pressing failure or trajectory deviation caused by device displacement.

[0042] This also includes a connecting pipe 501; the inflation pipes of at least three airbags 4 are connected in parallel via a multi-port connector; the parallel inflation pipes of at least three airbags 4 and the power supply pipe of the drive unit 202 are integrated into a connecting pipe 501, and at the end away from the main body 101, they are further separated into an air source pipe 502 and a power supply pipe 503; the power supply pipe 503 is connected to an external power source, and the air source pipe 502 is connected to an external gas source 505.

[0043] like Figure 7 and Figure 8 As shown, in this embodiment, the air path and the circuit are integrated together. The air path is used to inflate the airbag 4 to a constant pressure, and the circuit is used to drive the movement of the point β.

[0044] A pressure gauge 504 is installed on the air source pipeline 502 to detect the pressure of the airbag 4.

[0045] like Figure 8As shown, in this embodiment, the pressure gauge 504 makes the pressure of the airbag 4 visible, thereby indirectly monitoring the reaction force environment when point β moves. The constant pressure of the airbag 4 ensures the consistent softness of the contact surface, preventing the bionic trajectory movement of point β from being canceled by the stiff airbag 4 due to overpressure of the airbag 4, thus ensuring the realism and comfort of the bionic movement.

[0046] The gas source 505 can be a manual compression type or an air compressor.

[0047] The strap components can be secured using snap fasteners or Velcro.

[0048] The pressurizing component is detachably connected to the main body 101, and the pressurizing component can be installed according to the pressurizing requirements.

[0049] In the embodiment where the control unit 203 controls the pressurizing component 301 individually, the air intake channel of the airbag 4 on the outside of each pressurizing component 301 can also be set separately and controlled by the control unit 203, so that the independent pressurizing component 301 and the matching airbag 4 can perform pressurization operation independently.

[0050] In this embodiment, the pressure components can be flexibly configured according to the patient's specific body shape or examination site. For example, components with specific trajectory parameters can be installed at the site where the "abdominal push" action needs to be simulated, while ordinary components can be installed at the location where only a fixed position is needed.

[0051] The above description is merely a specific embodiment of this application. Under the guidance of the above teachings, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.
