Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and to a gastrointestinal endoscope, and more particularly to a gastrointestinal endoscope with a support function. Background Technology
[0002] Gastroscopy and colonoscopy are examinations that combine diagnosis and treatment. They are used to diagnose diseases of the digestive tract and have become one of the commonly used diagnostic and treatment techniques for digestive diseases. They have important clinical value in the diagnosis and differential diagnosis of digestive diseases. By using a gastroscope or colonoscope through the mouth or anus, it is possible to directly observe lesions in the esophagus, stomach, duodenum, colon, and rectum, especially for the observation of small lesions. In addition to directly diagnosing the presence of inflammation, ulcers, erosions, polyps, etc., it is also possible to take biopsies from the lesion sites for histopathological examination and to perform minimally invasive treatments for gastrointestinal diseases, such as polyp removal and endoscopic hemostasis.
[0003] During a normal gastroscopy or colonoscopy procedure, the surgeon needs to operate the handle with one hand and grasp the tip of the endoscope with the other hand to insert it. If a lesion is found during the examination, the surgeon needs to release the endoscope to control the biopsy forceps or surgical instruments. After the surgeon's hand leaves the control area of the endoscope, the endoscope will move along with it due to normal gastrointestinal peristalsis, causing it to shift. To solve this problem, the current method is for other medical staff to assist the surgeon in controlling the endoscope and maintaining its original position. The endoscope tube is inserted into the digestive tract through the patient's mouth / anus. Doctors typically need to control the insertion length of the tube, but this control is usually manual. Current technology requires additional human assistance to stabilize the endoscope during gastroscopy and colonoscopy to better complete the procedure. When the tube reaches the appropriate position, there is a lack of a fixed mechanism, making it easy for the endoscope tube to touch the digestive tract wall. Furthermore, while conventional gastroscopy involves administering local anesthetic to the patient beforehand to reduce throat irritation during the procedure, patient tolerance varies, and some patients may still experience nausea, vomiting, or other discomfort during the procedure. Also, the anesthesia time is limited. When a doctor adjusts the distal end of the endoscope to the expected position in the digestive tract, if the patient is uncooperative or resists, causing the distal end of the endoscope to move away from the expected position or change direction—for example, the human digestive tract is not a straight cavity but has multiple bends—accidentally pushing the catheter further into the body can damage the digestive tract and increase the patient's pain. If the endoscope catheter is accidentally pulled out or further inserted, the doctor needs to reposition it or make other adjustments, prolonging the operation time and ultimately exceeding the anesthesia maintenance time. This situation is very detrimental to the patient's health. Multiple adjustments to the endoscope can increase damage to the patient's gastrointestinal mucosa and increase the patient's discomfort.
[0004] Existing technologies provide devices for positioning colonoscope tubes. For example, utility model publication number CN209789814U provides an auxiliary support device for colonoscopy, including a lifting platform. A limiting groove for positioning the colonoscope tube is provided on the upper surface of the lifting platform. The two ends of the limiting groove pass through the two sides of the upper part of the lifting platform. The bottom of one end of the limiting groove has an outward and downward inclined surface. Its advantages are: it can free up one hand of medical staff, is convenient to use, improves the comfort of staff, reduces fatigue, and provides reliable positioning to prevent displacement; the height-adjustable lifting platform can be used to accommodate patients of different body types. However, in actual operation, when the patient lies on the hospital bed or other examination bed, the bed will be concave in shape, the bed will not be flat and the surface of the bed will be soft. When the support device or other auxiliary medical device mentioned above is placed on the bed, the device will deviate from its balance position and tilt. If the medical staff or the patient accidentally touches the tilting device during the examination, it is easy for it to tip over, which will cause the gastrointestinal tube that has been positioned to shift and affect the examination process.
[0005] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention
[0006] Gastroscopy and colonoscopy are invasive procedures. The typical procedure involves the surgeon using the left hand to adjust the endoscope, preventing movement and ensuring accurate observation, and the right hand to hold the flexible tubing, controlling its movement and assisting with rotation. If a lesion is detected, the surgeon must release the endoscope to manipulate biopsy forceps or surgical instruments. After the surgeon's hand leaves the endoscope, normal gastrointestinal motility can cause the endoscope to shift. Furthermore, patient tolerance to anesthesia varies; even with anesthesia, some patients may experience nausea, vomiting, or other discomfort during the procedure. Anesthesia duration is also limited. If the patient is uncooperative or resists when the distal end of the endoscope is positioned as intended in the digestive tract, the endoscope may deviate from its intended location or change direction. During the procedure, the surgeon needs to adjust the endoscope tube multiple times. The sliding of the endoscope tube within the digestive tract can cause damage. Therefore, it's crucial to minimize friction between the endoscope tube and the digestive tract to reduce patient pain. In practice, when the patient lies on the examination table, the pressure exerted on the table causes it to concave. Furthermore, the table surface is soft, and placing the support on an uneven surface causes it to tilt towards the concave direction. In this tilted state, the higher the center of gravity, the easier it is to tip over. When the support is raised, the overall height of the support relative to the table surface also increases. During the examination, with the gastrointestinal tract positioned in the groove of the support after the support is placed on the examination table, the support is subjected to external forces when the surgeon uses biopsy forceps or other surgical instruments to operate from the proximal end of the endoscope tube, increasing the risk of tipping over.
[0007] To address the shortcomings of existing technologies, this invention provides a gastrointestinal endoscope with a support function, comprising:
[0008] A gastrointestinal segment having a lumen to provide a passage for entry into the digestive tract from the outside, configured to extend into and remain at a port in the digestive tract.
[0009] A support portion is configured to hold a gastrointestinal segment located outside the digestive tract in a designated position, the gastrointestinal segment being detachably connected to the support portion.
[0010] The gastrointestinal endoscope also includes an adjustment module, which is configured to:
[0011] When the endoscope is on an inclined plane, the region of the support part at end G1, parallel to the direction of gravity component of the inclined plane, exerts pressure on the adjustment module, causing the adjustment module to undergo compressive deformation. The adjustment module then exerts a force F1 on the region at end G1. Furthermore, the region of the support part opposite to end G1 exerts a tensile force on the adjustment module, causing the adjustment module to undergo tensile deformation. The adjustment module then exerts a force F2 on the region opposite to end G1.
[0012] Preferably, the forces F1 and F2 are equal in magnitude but opposite in direction.
[0013] Preferably, the adjustment module is positioned below the support portion with the central axis of the support portion as the dividing line.
[0014] Preferably, the adjustment module includes: a connecting component configured as a cylinder with an internal elastic element.
[0015] Preferably, the support portion includes:
[0016] A stage with a recessed receiving groove to hold the gastrointestinal tract within the receiving groove;
[0017] The support is configured to adjust the height of the stage to accommodate the gastrointestinal tract at different heights;
[0018] A base is attached to one end of a bracket to support the platform.
[0019] Preferably, the receiving groove is disposed on the upper surface of the platform in such a way that it extends between the two opposite sides of the platform.
[0020] Preferably, the gastrointestinal tube portion is provided with a notch, and the receiving groove is provided with a protrusion adapted to the notch. The notch of the gastrointestinal tube portion and the protrusion of the support portion engage to hold the gastrointestinal tube portion in the support portion.
[0021] Preferably, a plurality of the connecting components are arranged opposite each other on the lower surface of the base with the central axis of the base as the dividing line, so that the magnitude of the force F1 generated by the connecting components is equal to the force F2.
[0022] Preferably, the force F1 is the resultant force generated by the connecting component corresponding to the end region of G1 on the end region of the support, and the force F2 is the resultant force generated by the connecting component corresponding to the region opposite to the end of G1 on the support and the region opposite to the end of G1.
[0023] Preferably, the bracket is provided with a screw for controlling the height of the bracket, and the screw adjusts the height of the bracket by rotation.
[0024] The beneficial effects of this invention are:
[0025] (1) On the one hand, the base plate and cylinder can increase the weight of the lower part of the support. On the other hand, when the support is tilted, the spring at the tilted end is subjected to pressure and produces compressive elastic deformation, which in turn produces an opposite force; the spring at the other end opposite to the tilted end is subjected to tension and produces tensile elastic deformation, which in turn produces an opposite force, ultimately making the support balanced and maintaining a stable state. Specifically, when the support is on the inclined surface of the bed, the support is subjected to gravity and the supporting force of the inclined surface of the bed. The component of gravity of the support parallel to the inclined surface of the bed is defined as G1, and the direction along the component of gravity G1 is defined as the G1 direction. When the support is tilted, the support region at the G1 end exerts pressure on the connecting rod of the cylinder. After being subjected to pressure, the connecting rod enters the cylinder and compresses the spring inside. The spring inside the cylinder undergoes compressive elastic deformation under pressure. At this time, the spring at the corresponding G1 end region generates a restoring force F1, which acts on the G1 end region of the support. Meanwhile, the connecting rod of the cylinder in the region opposite to the G1 end is subjected to tension, and the retainer is also subjected to a corresponding tension. The spring connected to the retainer is thus stretched and deformed by the tension. At this time, the spring in the region opposite to the G1 end generates a restoring force F2. The compression distance of the spring in the G1 end region and the stretching distance of the spring in the region opposite to the G1 end are equal. Accordingly, the forces F1 and F2 are equal in magnitude and opposite in direction, ultimately keeping the support in balance.
[0026] (2) This invention helps solve the problem of doctors controlling the endoscope, helps doctors fix the endoscope body, keeps the endoscope in its original position, prevents the surgical instruments from shifting due to the movement of the endoscope, causing incomplete surgical wounds, damage to normal mucosa, blood vessels and tissues, and causing new trauma to patients; shortens the operation time, reduces the number of times the doctor adjusts the endoscope, makes it easier for doctors to complete the examination and surgery, and prevents the operation time from being too long and causing physical and mental pain to patients.
[0027] (3) Wide applicability: It can be fixedly placed on the examination bed and its height can be adjusted at any time according to patients of different heights and weights, making it convenient and easy to install and place. Attached Figure Description

The receiving groove 211 is provided on the stage 210 in such a way that it extends between two opposite sides of the stage 210. According to a preferred embodiment, a locking member 212 is provided on the stage 210. Preferably, the locking member 212 is provided above the receiving groove 211 along the radial direction of the receiving groove 211.

When the guide tube is inserted into the desired position in the digestive tract, the operator places the guide tube, which is outside the digestive tract, into the receiving groove 211, so that the recesses of the outer tube wall of the guide tube engage with the protrusions of the receiving groove 211 wall, thereby stably holding the guide tube in the receiving groove 211 and preventing relative sliding between the guide tube and the port.
[0063] The support 200 is used to fix medical instruments, such as gastroscopes and colonoscopes, in the position specified by the operating physician to reduce accidental displacement of the gastroscopes and colonoscopes during the surgical procedure.
[0064] like Figure 4 and 5 As shown, the gastrointestinal endoscope also includes an adjustment module 300. The adjustment module 300 includes a base plate and a connecting assembly 310. Preferably, the connecting assembly 310 includes a cylinder 311 and a connecting rod 312 disposed at one end of the cylinder 311. According to a preferred embodiment, the cylinder 311 is disposed between the upper surface of the base plate and the lower surface of the base 230. The cylinder 311 is connected to the lower surface of the base 230 via the connecting rod 312. The cylinder 311 contains a retainer 311.1 and an elastic element 311.2. The end of the connecting rod 312 opposite to the base 230 is connected to the retainer 311.1 within the cylinder 311. The end of the elastic element 311.2 is connected to the retainer 311.1. Preferably, the elastic element 311.2 is a spring. Preferably, the cylinders 311 are evenly arranged between the upper surface of the base plate and the lower surface of the base 230 to maintain the stability of the support portion 200. Preferably, the number of cylinders 311 disposed at opposite ends of the base 230 is the same. The cylinders 311 are disposed opposite each other on the lower surface of the base 230 in such a way that the support portion 200 is divided into two equal regions by the center line of the support portion 200, that is, the number of cylinders 311 in the two regions is the same and the arrangement is symmetrical.
[0065] This embodiment uses an adjustment module 300 comprising two cylinders 311 as an example for illustration. The adjustment module 300 includes a base plate, a first cylinder, and a second cylinder. Preferably, the center of the base plate coincides with the center of the base 230. Preferably, the base 230 is cuboid in shape. The first cylinder and the second cylinder are respectively located at the midpoints of the two short sides of the lower surface of the base 230.
[0066] When the support part 200 is on the inclined surface of the bed, the inclination angle is α. The support part 200 is subjected to gravity and the supporting force of the inclined surface of the bed. The component of gravity of the support part 200 parallel to the inclined surface of the bed is defined as G1, the direction along the component of gravity G1 is defined as the G1 direction, and the end of the support part 200 facing the G1 direction is defined as the G1 end. When the first cylinder is at end G1, the second cylinder is at the opposite end of end G1. In the tilted state, the connecting rod 312 of the first cylinder is subjected to pressure from end G1 and extends into cylinder 311. The spring in the first cylinder is compressed and undergoes elastic deformation through the retainer 311.1. After the spring undergoes elastic deformation, it generates a restoring force to return to its natural length. At this time, the compressed spring in the first cylinder generates an upward restoring force F1. Therefore, end G1 will be subjected to the restoring force F1. At the same time, the connecting rod 312 of the second cylinder is subjected to tension from the end opposite to end G1, which stretches the spring in the second cylinder. After the spring is subjected to tension, it undergoes elastic deformation. At this time, the stretched spring in the second cylinder generates a downward restoring force F2. Therefore, the end opposite to end G1 is subjected to the restoring force F2. In the tilted state, the downward tilt distance of end G1 is equal to the height of the opposite end of end G1 rising, that is, the length of the spring compression in the first cylinder of end G1 is equal to the length of the spring extension in the second cylinder. F1 and F2 are the same in magnitude but opposite in direction, so the support part 200 can maintain balance.
[0067] When the support 200 is on the inclined surface of the bed, the inclination angle is β, where β is greater than α. In the inclined state, the connecting rod 312 of the first cylinder is subjected to the pressure of the G1 end and extends into the cylinder 311. The spring in the first cylinder is compressed and undergoes elastic deformation through the retainer 311.1. After the spring undergoes elastic deformation, it will generate a restoring force to return to its natural length. As the inclination angle β increases, the compressed length of the spring in the first cylinder increases, and the compressed spring in the first cylinder will generate an upward restoring force F3 greater than F1. At the same time, the stretched length of the spring in the second cylinder increases. At this time, the stretched spring in the second cylinder will generate a downward restoring force F4 greater than F2. F3 and F4 are the same in magnitude but opposite in direction, and the support 200 remains in balance.
[0068] On the one hand, the base plate and cylinder 311 increase the weight of the lower part of the support 200. On the other hand, at different tilt angles, the compressed length of the spring in the cylinder 311 at end G1 and the stretched length of the spring in the cylinder 311 at the opposite end of G1 are the same. Therefore, the magnitude of the restoring force F1 is equal to the magnitude of F2, and the direction of F1 is opposite to the direction of F2. Alternatively, the magnitude of F3 is equal to the magnitude of F4, and the direction of F3 is opposite to the direction of F4. Ultimately, this balances the forces on the support 200, maintaining a stable state. When α is less than β, F1 is less than F3, and F2 is less than F4.

[0070] This embodiment is another preferred method, and the content that is repeated in Embodiment 1 will not be repeated.
[0071] An adjustment module 300 is provided on the lower surface of the stage 210. The adjustment module 300 is used to adjust the center of gravity of the gastroscope to ensure that the gastroscope is in a balanced position. The balanced position is defined as the center of gravity position when the gastroscope is placed in a flat and stable position. According to a preferred embodiment, the adjustment module 300 includes a first moving component and a second moving component. Preferably, the initial state of the first moving component is coaxial with the axial direction of the receiving groove 211. Preferably, the initial state of the second moving component is coaxial with the radial direction of the receiving groove 211. Preferably, the first moving component and the second moving component move independently of each other. Preferably, the first moving component and the second moving component have similar structures. The second moving component will not be described in detail in this embodiment. The first moving component maintains the balanced position of the support part 200 on the axis located in the second direction 500. The second moving component maintains the balanced position of the support part 200 on the axis located in the third direction 600. Preferably, the second moving component is disposed transversely to the first component on the lower surface of the stage 210. The second moving component is connected to the lower surface of the stage 210.
[0072] Preferably, the adjustment module 300 further includes a support assembly. The support assembly includes a first horizontal axis, a second horizontal axis, a third horizontal axis, a fourth horizontal axis, a first vertical rod, a second vertical rod, and a connecting frame. The connecting frame is connected to the lower surface of the stage 210.
[0073] The two ends of the first vertical rod are connected to the first and second horizontal axes, respectively. Preferably, the first vertical rod is pivotable about the first and second horizontal axes. The two ends of the second vertical rod are connected to the third and fourth horizontal axes, respectively. Preferably, the second vertical rod is pivotable about the third and fourth horizontal axes. The first horizontal axis is connected to the first end of the connecting frame. The third horizontal axis is connected to the second end of the connecting frame. The second and fourth horizontal axes extend between and are connected to the brackets 220.
[0074] The first moving assembly includes a cylinder 311 and a connecting rod 312. A retainer 311.1 is provided within the cylinder 311. The connecting rod 312 is connected to the retainer 311.1 within the cylinder 311. Preferably, a first retainer and a second retainer are respectively provided at both ends of the cylinder 311. A compression spring is provided between the first retainer and the second retainer. Preferably, the connecting rod 312 includes a first connecting rod connected to the first retainer and a second connecting rod connected to the second retainer. According to a preferred embodiment, any one of the connecting rods 312 can compress the spring and, when compressing the spring, can enter the cylinder 311 independently of the other connecting rod 312.
[0075] Preferably, a baffle is provided at a relative position at the front end of the connecting rod 312. The baffle includes a first baffle and a second baffle. Preferably, the first baffle is capable of rotating integrally with the first longitudinal rod. Preferably, the second baffle is capable of rotating integrally with the second longitudinal rod.
[0076] When the support 200 is naturally placed on a flat surface, the compression spring inside the cylinder 311 is at its natural length, and there is no interaction force between the baffle and the connecting rod 312. Preferably, when the compression spring is at its natural length, the distance between the baffle and the connecting rod 312 can be zero. Preferably, when the compression spring is at its natural length, the distance between the baffle and the connecting rod 312 can be greater than zero.
[0077] When the support 200 is placed on the bed and tilted, the first connecting rod, under the action of a gravitational force parallel to the tilted plane, separates from the first baffle. The second longitudinal rod, under the action of a gravitational force parallel to the tilted plane, moves toward the second baffle, which in turn moves toward the second connecting rod. The second baffle applies a force toward the cylinder 311 to the second connecting rod, causing the second retaining member to compress the spring inside the cylinder 311. The spring thus accumulates a restoring force to return to its natural length. The greater the tilt angle, the greater the pressure on the spring, and the greater the corresponding accumulated restoring force.
[0078] Example 3
[0079] This embodiment provides another preferred implementation of a gastrointestinal endoscope with support function, and the content that is repeated in Embodiments 1 and 2 will not be repeated.
[0080] When the distal end of the gastrointestinal segment 100 is adjusted to the expected position in the digestive tract, the support portion 200 holds the gastrointestinal segment 100 in place. In actual operation, patients may become uncooperative or resistant, causing the distal end of the endoscope to leave the expected position. This displacement can occur when the gastrointestinal segment 100 naturally detaches from its port along the digestive tract's pathway, or when it bends, twists, or curls within the digestive tract. In particular, the support portion 200 exerts a force on the gastrointestinal segment 100. When the gastrointestinal segment 100 is pulled out or has a tendency to be pulled out, it is prone to bending within the digestive tract, a phenomenon that the operator cannot directly observe from the outside, leading to misjudgment.
[0081] To address this issue, the gastrointestinal segment 100 of the gastrointestinal endoscope provided in this embodiment is equipped with a detection component to detect displacement changes in the gastrointestinal segment 100. Preferably, the detection component is a displacement detection component. According to a preferred embodiment, the detection component includes a distal displacement component disposed at the distal end of the gastrointestinal segment 100 and a proximal displacement component disposed at the port. Preferably, the detection component is detachably connected to the gastrointestinal segment 100. Preferably, the detection component is communicatively connected to a processor to analyze the detection results received from the detection component. Preferably, the detection component can be a displacement sensor.
[0082] According to a preferred embodiment, the processor is configured to: determine that the gastrointestinal segment 100 has displaced from the port in a natural state without bending when displacement of the gastrointestinal segment 100 is detected and the displacements of the distal displacement component and the proximal displacement component are equal; and determine that the gastrointestinal segment 100 has bent within the digestive tract when displacement of the gastrointestinal segment 100 is detected and the displacement detected by the distal displacement component is greater than the displacement detected by the proximal displacement component. This setup determines the state of the gastrointestinal segment 100 within the digestive tract by comparing the displacements of the two sets of displacement components. Its advantages include: helping the operator determine the state of the gastrointestinal segment 100 within the digestive tract when it dislodges. For example, if it is determined that the gastrointestinal segment 100 has dislodged from the port without bending, the operator does not need to remove the segment again but can directly place the dislodged portion back into the digestive tract, allowing the distal end of the gastrointestinal segment 100 to return to the expected position. Conversely, if it is determined that the gastrointestinal segment 100 has bent within the digestive tract, the operator needs to remove the segment and then... The new component is inserted into the intended position. In addition, during the insertion process, by comparing whether the displacements of the distal and proximal displacement components are equal, the operator can also determine whether the gastrointestinal segment 100 in the digestive tract has become bent. If the displacements of the distal and proximal displacement components remain equal throughout the insertion process, it indicates that the gastrointestinal segment 100 has entered the digestive tract in a natural state without bending. When the displacement of the proximal displacement component is greater than that of the distal displacement component, it indicates that the gastrointestinal segment 100 in the digestive tract has become bent, and the operator needs to adjust or handle this situation.
