Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary equipment, and in particular relates to an auxiliary device for a digestive endoscope and a method of using the same. Background Art

[0002] Gastrointestinal endoscopy is a common medical procedure used to observe the internal conditions of the digestive system; the doctor or endoscopic technician will prepare the endoscopic equipment, including the endoscope, light source, camera, and necessary cleaning agents. Endoscope insertion: The doctor will gradually insert the endoscope through the patient's mouth and esophagus into the stomach and small intestine (if it is a gastroscope) or large intestine (if it is a colonoscopy). During the insertion process, the doctor will guide the operation by observing the images transmitted by the endoscope's camera.

[0003] For example, the Chinese patent with announcement number CN110368103B discloses a semi-automatic digestive endoscopy diagnosis and treatment auxiliary device, which belongs to the field of medical equipment technology and includes a fixing mechanism, a lifting mechanism, a rotating mechanism, an adjusting mechanism and a control mechanism. The lifting mechanism is installed at the upper end of the fixing mechanism, the rotating mechanism is installed at the upper end of the lifting mechanism, the adjusting mechanism is installed at the end of the rotating mechanism, and the control mechanism is arranged beside the adjusting mechanism. The lifting mechanism includes a lifting assembly and a fixing assembly, and the fixing assembly is installed at the upper end of the lifting assembly. The rotating mechanism and the adjusting mechanism are respectively provided with a first locking assembly and a second locking assembly, and the first locking assembly and the second locking assembly are both connected to the control mechanism. The invention can improve the firmness of the fixation of the digestive endoscope, avoid the digestive endoscope from moving significantly under the action of external force, thereby posing a safety hazard to the treatment, and can support the doctor's arm during use, with more comprehensive functions.

[0004] The shortcomings of the existing technology are that, under the current background of digestive endoscopy operation technology, there are certain limitations. Specifically, when the digestive endoscope is inserted into the patient's body through the connecting cable and the end, due to differences in the operating strength and proficiency of the operator, unstable movements of the hand-held connector often occur. In this case, the end of the endoscope may move or rotate randomly in the patient's body, resulting in the inability to accurately control the stability of its angle. This phenomenon not only increases the difficulty of digestive endoscopy operation, but also brings significant inconvenience to accurate observation inside the patient's body.

[0005] Based on this, the present invention designs an auxiliary device for digestive endoscopy and a method of using the same to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to propose an auxiliary device for digestive endoscope and a method of using the same in order to solve the problem that the end of the endoscope may move or rotate randomly in the patient's body, resulting in the inability to accurately control the stability of its angle.

[0025] A method for using an auxiliary device for digestive endoscopy, the method comprising the following steps:

[0026] First, put the guard plate on the patient's mouth through the tightening belt, and then insert the connecting cable into the patient's body through the mouth. When the connecting cable is inserted into the corresponding position, first squeeze the first limit plate and the movable rod with your fingers to move. When the movable rod and the magnetic rod move close to the connecting cable, the magnetic force between the magnetic rod and the magnetic block controls the sliding block rod to slide upward. After the sliding block rod is separated from the blocking groove, the second elastic component controls the sliding rod and the clamping plate to move. The clamping plate moves to clamp the connecting cable, and the second limit plate is separated from the contact rod.

[0027] When the third elastic component controls the movement of the extrusion plate, the gas in the piston cylinder is sucked through the air pipe. When the air pressure in the piston cylinder is reduced, the piston plate and the second limit rod are controlled to move away from the second limit groove. At this time, the second limit rod releases the limit on the second limit groove, and the buffer plate is buffered by the fourth elastic component when the patient's teeth are bitten. When the first limit rod is separated from the first limit groove, the rotation of the rotating drum can be controlled. When the connecting cable is adjusted to a suitable position and angle, the first limit plate is released, and the first elastic component controls the movable rod and the first limit rod to move until the first limit rod is inserted into the corresponding first limit groove, thereby completing the limit on the rotating drum and the connecting cable.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, a splint, a sliding rod, a first limiting rod, a first limiting groove, a connecting bearing and a rotating cylinder are adopted. The first limiting plate is pressed to separate the first limiting rod from the first limiting groove. At the same time, the magnetic force between the magnetic rod and the magnetic block is used to control the separation of the sliding blocking rod from the blocking groove. Under the action of the second elastic component, the splint can firmly clamp the connecting cable, effectively avoiding the problem of the cable sliding freely in the patient's body; when the operator releases the first limiting plate, the first elastic component quickly resets the first limiting rod to the first limiting groove, thereby realizing precise control of the rotation of the connecting cable, ensuring that the angle of the connecting cable is effectively limited after it is rotated to a specified angle, avoiding arbitrary rotation, and greatly improving the stability of angle control. This improvement not only significantly reduces the difficulty of operating the digestive endoscope, but also achieves obvious optimization in the observation accuracy in the patient's body, thereby improving the overall diagnosis and treatment efficiency and the safety and comfort of the patient.

[0030] 2. In the present invention, while the splint firmly clamps the connecting cable, the mechanism of the contact rod is released, and the extrusion plate draws the gas in the piston cylinder into the air storage cylinder through the action of the trachea, thereby cleverly controlling the separation of the second limit rod and the second limit groove, and releasing the limit on the buffer plate; this design enables the buffer plate to perform a small vertical movement along the guide groove, providing a gentle buffer for the occlusal area of ​​the patient's teeth. The application of the fourth elastic component not only significantly improves the patient's comfort, but also effectively avoids possible damage to the patient's teeth during operation. This humanized design fully considers the patient's feelings, ensures the safety and comfort during the operation of digestive endoscopy, and further optimizes the overall experience of endoscopic diagnosis and treatment.

[0031] 3. In the present invention, the expansion tube effectively supports the patient's teeth. At the same time, the guard plate and the expansion tube are firmly fixed to the patient's mouth by the tightening belt, ensuring that the patient's mouth remains in a moderately expanded state. This design cleverly avoids the risk of damage caused by the connecting cable being bitten by the patient's teeth during operation; thanks to the application of this device, the use and placement of the digestive endoscope become smoother and safer. The combination of the guard plate and the expansion tube not only ensures the accuracy of the endoscopic operation, but also improves the patient's sense of safety and comfort, providing a more reliable and convenient condition for endoscopic examination and treatment.

[0046] Please see attached Figure 1 -Attached Fig.11 The present invention provides a technical solution: an auxiliary device for a digestive endoscope, comprising an endoscope connector 1 and a guard plate 6, wherein a light guide plug 5 is connected to the bottom of the endoscope connector 1, a video interface 2 is provided on the front of the endoscope connector 1, an angle knob 3 is provided on the side of the endoscope connector 1, the guard plate 6 is arranged outside the connecting cable 4 connected to the back of the endoscope connector 1, a tightening belt 15 is fixedly connected to the back of the guard plate 6, a rotation adjustment mechanism 7 is provided on the front of the guard plate 6, two sliding clamping mechanisms 8 are provided inside the rotation adjustment mechanism 7, an extrusion air outlet mechanism 9 connected to the front of the guard plate 6 is provided outside the sliding clamping mechanism 8, an expansion tube 10 is fixedly connected to the back of the guard plate 6, two connecting holes 11 are provided outside the expansion tube 10, a guide groove 12 is provided in the connecting hole 11, a buffer contact mechanism 13 slidably connected to the guide groove 12 is provided in the connecting hole 11, a movable blocking mechanism 14 arranged in the expansion tube 10 is slidably connected in the buffer contact mechanism 13, and a sliding limiting mechanism 16 is slidably connected in the rotation adjustment mechanism 7.

[0047] The guard plate 6, the expansion tube 10 and the tightening belt 15 are used. The expansion tube 10 supports the patient's teeth, and the guard plate 6 and the expansion tube 10 are stably placed on the patient's mouth through the tightening belt 15, so that the patient's mouth is in a stretched state;

[0048] Specifically, Figure 2 and Figure 5-7 As shown, the rotation adjustment mechanism 7 includes a support plate 71 and a connecting bearing 72 arranged on the front side of the guard plate 6. The connecting bearing 72 is rotatably connected to a rotating cylinder 77. A movable limiting component 76 is penetrated through the outer arc surface of the rotating cylinder 77. A first limiting groove 73 is opened on the front side of the support plate 71. The movable limiting component 76 is slidably arranged in the first limiting groove 73.

[0049] Two sliding grooves 74 are provided in the rotating drum 77 , sliding holes 75 are provided on the left and right sides of the rotating drum 77 , the sliding clamping mechanism 8 is provided in the sliding holes 75 , and the sliding limiting mechanism 16 is provided in the sliding groove 74 .

[0050] The movable limiting assembly 76 includes a linear bearing 761 which passes through the outside of the rotating cylinder 77, a movable rod 762 which is slidably connected inside the linear bearing 761, a first limiting plate 764 which is fixedly connected to one end of the movable rod 762 which is located outside the rotating cylinder 77, a magnetic rod 763 is provided outside the movable rod 762, a first elastic assembly 765 which is fixedly connected to the linear bearing 761 and the first limiting plate 764 is provided on the outer sleeve of the movable rod 762, and a first limiting rod 766 which is slidably connected to the first limiting groove 73 is fixedly connected to the back side of the first limiting plate 764.

[0051] The linear bearing 761 enables the movable rod 762 and the first limiting plate 764 to stably perform linear movements without rotation. The connecting bearing 72 limits the rotating drum 77 and the clamping plate 82, so that the two clamping plates 82 can smoothly cooperate to achieve stable clamping of the connecting cable 4. At the same time, the rotating drum 77 can rotate smoothly and stably. When the first limiting plate 764 is controlled to move, the first limiting rod 766 can be controlled to separate from the first limiting groove 73. At this time, the rotating drum 77 and the clamping plate 82 can be controlled to rotate. After the first limiting plate 764 is loosened, the first elastic component 765 controls the first limiting rod 766 to be inserted into the first limiting groove 73 to limit the rotating drum 77.

[0052] Specifically, Figure 5 and Figure 8 As shown, the sliding clamping mechanism 8 includes a sliding rod 81 slidably connected in the sliding hole 75, one end of the sliding rod 81 located in the rotating cylinder 77 is fixedly connected to a clamping plate 82, and one end of the sliding rod 81 located outside the rotating cylinder 77 is fixedly connected to a second limiting plate 83. A blocking groove 84 is provided on the front side of the sliding rod 81, and two positioning rods 85 are fixedly connected to the outside of the sliding rod 81. The positioning rods 85 are arranged in the rotating cylinder 77, and the outer sleeve of the sliding rod 81 is provided with a second elastic component 86 fixedly connected to the rotating cylinder 77 and the second limiting plate 83.

[0053] The sliding rod 81 and the sliding hole 75 are used to make the clamping plate 82 move smoothly and stably in a straight line. The second elastic component 86 is used to automatically control the two clamping plates 82 to move closer to each other after the sliding rod 81 loses its obstruction, so as to achieve the clamping and positioning of the connecting cable 4. The sliding blocking rod 161 and the blocking groove 84 cooperate with each other, and the sliding blocking rod 161 limits the blocking groove 84 and the sliding rod 81, so that the clamping plate 82 is at a position away from the connecting cable 4.

[0054] Specifically, Figure 3 , Figure 5 and Figure 8As shown, the extrusion air outlet mechanism 9 includes an air cylinder 91 fixedly connected to the front side of the protective plate 6, an extrusion plate 92 is slidably connected inside the air cylinder 91, a contact rod 93 is fixedly connected to the side of the extrusion plate 92 close to the connecting cable 4, the contact rod 93 passes through and is slidably connected to the side of the air cylinder 91, the contact rod 93 is slidably connected to the outside of the second limiting plate 83, the outer sleeve of the contact rod 93 is provided with a third elastic component 94 fixedly connected to the air cylinder 91 and the extrusion plate 92, and the back of the air cylinder 91 is provided with an air pipe 95 connected to the movable blocking mechanism 14.

[0055] The contact rod 93 is squeezed by the second limit plate 83 away from the connecting cable 4, so that the extrusion plate 92 is in a squeezed state. The elastic force applied by the third elastic component 94 to the extrusion plate 92 and the contact rod 93 cooperates with the second limit plate 83 to keep the extrusion plate 92 stable. After the contact rod 93 loses the squeezing of the second limit plate 83, the third elastic component 94 controls the movement of the extrusion plate 92, and the extrusion plate 92 will suck the gas in the piston cylinder 141 through the air pipe 95.

[0056] Specifically, Figure 4 and Figure 9-10 As shown, the buffer contact mechanism 13 includes a buffer plate 131 slidably connected in the connecting hole 11, the side of the buffer plate 131 is fixedly connected with a guide block 133 slidably connected in the guide groove 12, the guide block 133 is fixedly connected with a fourth elastic component 134, the fourth elastic component 134 is fixedly connected in the guide groove 12, a second limiting groove 132 is opened on the side of the buffer plate 131, and the movable blocking mechanism 14 is slidably connected in the second limiting groove 132.

[0057] After the buffer plate 131 loses the limit of the second limit rod 143, the guide block 133 can slide vertically in the guide groove 12, and at the same time squeeze or stretch the fourth elastic component 134, so that when the patient's teeth bite on the buffer plate 131, the patient's teeth are buffered and protected, making the comfort better.

[0058] Specifically, Figure 9-11 As shown, the movable blocking mechanism 14 includes a piston cylinder 141 arranged in the expansion cylinder 10, a piston plate 142 is slidably connected in the piston cylinder 141, a second limiting rod 143 is fixedly connected to the side of the piston plate 142, the second limiting rod 143 is slidably connected in the second limiting groove 132, a fifth elastic component 144 is fixedly connected to the outside of the piston plate 142, the other end of the fifth elastic component 144 is fixedly connected in the piston cylinder 141, and the piston cylinder 141 is connected to the air pipe 95.

[0059] When the gas in the piston cylinder 141 is sucked out, the piston plate 142 and the second limiting rod 143 can be controlled to move downward, and the second limiting rod 143 can be controlled to separate from the second limiting groove 132, thereby releasing the limiting of the buffer plate 131;

[0060] Specifically, Figure 5 and Figure 8 As shown, the sliding limiting mechanism 16 includes a sliding blocking rod 161 slidably connected in the blocking groove 84 and the sliding groove 74, the top of the sliding blocking rod 161 is fixedly connected to a magnetic block 162, the top of the sliding blocking rod 161 is fixedly connected to a sixth elastic component 163, the other end of the sixth elastic component 163 is fixedly connected to the inner wall of the sliding groove 74, and the side of the magnetic block 162 close to the magnetic rod 763 has opposite magnetism.

[0061] The sliding baffle rod 161 cooperates with the blocking groove 84 to keep the sliding rod 81 and the clamping plate 82 away from the connecting cable 4, so that the connecting cable 4 can pass through the rotating drum 77 smoothly. At the same time, the magnetic force between the magnetic block 162 and the magnetic rod 763 controls the sliding baffle rod 161 to slide upward and separate from the blocking groove 84 when the first limit plate 764 is pressed. The elastic force applied by the sixth elastic component 163 to the sliding baffle rod 161 can ensure that the sliding baffle rod 161 is stably located in the blocking groove 84 when it is not controlled by the magnetic force.

[0062] A method for using an auxiliary device for digestive endoscopy, the method comprising the following steps:

[0063] First, the guard plate 6 is put on the patient's mouth through the tightening belt 15, and then the connecting cable 4 is inserted into the patient's body through the mouth. When the connecting cable 4 is inserted into the corresponding position, the first limit plate 764 and the movable rod 762 are squeezed by fingers to move. When the movable rod 762 and the magnetic rod 763 move close to the connecting cable 4, the magnetic force between the magnetic rod 763 and the magnetic block 162 controls the sliding block rod 161 to slide upward. After the sliding block rod 161 is separated from the blocking groove 84, the second elastic component 86 controls the sliding rod 81 and the clamping plate 82 to move. The clamping plate 82 moves to clamp the connecting cable 4, and the second limit plate 83 is separated from the contact rod 93;

[0064] When the third elastic component 94 controls the movement of the extrusion plate 92, the gas in the piston cylinder 141 is sucked through the air pipe 95. When the air pressure in the piston cylinder 141 is reduced, the piston plate 142 and the second limiting rod 143 are controlled to move away from the second limiting groove 132. At this time, the second limiting rod 143 releases the limitation on the second limiting groove 132, and the buffer plate 131 is buffered by the fourth elastic component 134 when being bitten by the patient's teeth. When the first limiting rod 766 is separated from the first limiting groove 73, the rotating drum 77 can be controlled to rotate. When the connecting cable 4 is adjusted to a suitable position and angle, the first limiting plate 764 is released, and the first elastic component 765 controls the movable rod 762 and the first limiting rod 766 to move until the first limiting rod 766 is inserted into the corresponding first limiting groove 73, thereby completing the limitation of the rotating drum 77 and the connecting cable 4.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
