Detailed Embodiments
[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention and do not specifically limit the present invention.
[0030] Embodiment 1: An intubation guide wire device with visualization function, as Figures 1-4 shown, comprising a display 1. A cavity is formed inside the display 1. A piston frame 101 is slidably connected to one side of the display 1 close to the cavity in the up-and-down direction. The piston frame 101 and the cavity of the display 1 form a cylinder-piston structure. An intubation body 2 is connected to the upper part of the display 1. The intubation body 2 communicates with the cavity inside the display 1. A guide wire body 3 is arranged inside the intubation body 2. The right end of the intubation body 2 and the guide wire body 3 form a cylinder-piston structure. The left end of the guide wire body 3 is fixedly connected with a push frame 4. An external thread groove is formed in the right part of the push frame 4. An endoscope 5 is rotatably connected to the left part of the push frame 4. A torsion spring 6 is fixedly connected between the push frame 4 and the endoscope 5. A steering cylinder 7 is clamped inside the intubation body 2 through a first fixing member. An internal thread groove is formed in the steering cylinder 7. The external thread groove of the push frame 4 moves leftward and is in threaded cooperation with the thread groove of the steering cylinder 7. A guide frame 8 is clamped inside the intubation body 2 through a second fixing member. A frustum-shaped hole is formed inside the guide frame 8. The aperture of the right end of the frustum-shaped hole of the guide frame 8 is smaller than the aperture of the left end of the frustum-shaped hole of the guide frame 8. The right end of the frustum-shaped hole limits the push frame 4 and the endoscope 5. When the endoscope 5 extends leftward into the frustum-shaped hole of the guide frame 8, the endoscope 5 deflects to the right under the action of the torsion spring 6 and contacts the inner wall of the guide frame 8.
[0031] When using this device to detect a patient's body, after moving and introducing the intubation body 2 into the target position inside the human body, when it is necessary to adjust the angle of the endoscope 5, gradually push the piston frame 101 upward. The piston frame 101 pushes the gas in the inner cavity of the display 1 into the intubation body 2. Under the action of the air pressure, the guide wire body 3 slides along the intubation body 2 to the side away from the display 1. The guide wire body 3 pushes the endoscope 5 and the torsion spring 6 to move synchronously to the side away from the display 1 through the push frame 4. When the endoscope 5 is disengaged from the limit of the right side port of the guide frame 8, under the action of the torsion spring 6 resetting, the endoscope 5 deflects by a certain angle relative to the push frame 4. When the external thread groove of the push frame 4 moves to the internal thread groove of the steering cylinder 7, when the push frame 4 continues to move, it will be rotated by the action of the steering cylinder 7 at the same time, thereby driving the endoscope 5 to move and rotate at the same time to observe the specific situation of the target area from multiple angles. In this way, after reaching the target position, the present invention only needs to push the piston frame 101 upward to adjust the angle of the endoscope 5 alone, avoiding the rotation of the intubation guide wire relative to the internal mucosal layer or blood vessel wall of the human body, reducing the harm to the patient, being not only simple and flexible in operation, but also not requiring additional externally configured driving components.
[0032] After the detection is completed, simply gradually pull down the piston holder 101, so that the guide wire body 3, the push frame 4, the endoscope 5, the torsion spring 6, the steering cylinder 7 and the guide frame 8 move reversely and reset under the action of negative pressure. During this process, the endoscope 5 is gradually reversely deflected and reset under the extrusion action of the inner side surface of the guide frame 8, and the torsion spring 6 returns to the state of deforming and storing energy.
[0033] As Figure 5 and Figure 6 shown, the first fixing member is set as a clamping cylinder 9. The clamping cylinder 9 is clamped in the intubation body 2, and the clamping between the clamping cylinder 9 and the intubation body 2 is a tight-fitting structure, so that a predetermined pushing and pulling force needs to be applied between the two to achieve relative movement. The steering cylinder 7 is slidably connected to the clamping cylinder 9. The left side of the steering cylinder 7 contacts the clamping cylinder 9, so as to limit the left side of the steering cylinder 7. The right side of the steering cylinder 7 moves to the right and contacts the clamping cylinder 9, so as to limit the right side of the steering cylinder 7. Two slide bars 10 symmetrically distributed in the front and back along the clamping cylinder 9 are slidably connected to the clamping cylinder 9 in the left-right direction. A first spring 11 is fixedly connected between the slide bar 10 and the clamping cylinder 9.
[0034] During the above-mentioned reset process, before the endoscope 5 extends into the intubation body 2, it will reverse under the cooperation of the external thread groove of the push frame 4 and the internal thread groove of the steering cylinder 7, resulting in the rotating endoscope 5 acting on the mucous membrane layer or blood vessel wall inside the human body again. To further reduce the damage, through the following settings, the endoscope 5 is reversed and reset after extending into the intubation body 2. The specific operation is as follows: Through the tight-fitting of the clamping cylinder 9 and the intubation body 2, the steering cylinder 7 is limited in the intubation body 2 through the clamping cylinder 9. When the piston holder 101 is pushed upward, since the left side surface of the steering cylinder 7 is limited by the clamping cylinder 9, the steering cylinder 7 cannot move, and the push frame 4 moves leftward relative to the steering cylinder 7. When the piston holder 101 is pulled downward, since the steering cylinder 7 is in threaded cooperation with the push frame 4 and the right side surface of the steering cylinder 7 is not limited, when the push frame 4 moves rightward under the action of negative pressure, it drives the steering cylinder 7 and the slide bar 10 to move synchronously to the right as a whole, and the first spring 11 is compressed. In this way, the push frame 4 first extends into the intubation body 2. When the right side surface of the steering cylinder 7 contacts the clamping cylinder 9, the steering cylinder 7 cannot continue to move to the right, while the push frame 4 continues to move rightward and reverse relative to the steering cylinder 7 under the action of negative pressure. When the external thread groove of the push frame 4 is disengaged from the internal thread groove of the steering cylinder 7, under the reset action of the first spring 11, the slide bar 10 drives the steering cylinder 7 to move leftward and reset.
[0035] Moreover, the detachable design of the clamping cylinder 9 and the guide frame 8 enables the guide wire body 3, the push frame 4, the endoscope 5, the torsion spring 6, the steering cylinder 7, the slide bar 10 and the first spring 11 thereon to be withdrawn from the intubation body 2 accordingly. In this way, even if the intubation body 2 cannot be used again, the remaining components can be disinfected and reused.
[0036] As Figure 7As shown in the figure, the second fixing member is provided as an elastically guiding plate 12 distributed circumferentially. The elastically guiding plate 12 is clamped inside the intubation body 2. The elastically guiding plate 12 is fixedly connected to the cartridge 9, and the clamping between the elastically guiding plate 12 and the intubation body 2 is a tight-fitting structure, such that a predetermined pushing and pulling force needs to be applied between the two to achieve relative movement. The elastically guiding plate 12 is slidably connected to the guiding frame 8. The guiding frame 8 is fixed on the elastically guiding plate 12 through an elastic clamp 13. A clamping groove is formed in the outer wall of the guiding frame 8 along the circumference. When the clamp 13 is pressed against the clamping groove of the guiding frame 8, the pressed portion of the elastically guiding plate 12 undergoes adaptive deformation.
[0037] Before the cartridge 9 is snapped into the intubation body 2, first move the guiding frame 8 left or right relative to the elastically guiding plate 12 to adjust the relative initial position of the guiding frame 8 and the endoscope 5. After determining the position of the adjusted guiding frame 8, fix the guiding frame 8 on the elastically guiding plate 12 through the clamp 13. If the guiding frame 8 is initially more to the left, then after the endoscope 5 moves left relative to the guiding frame 8, the deflection angle of the endoscope 5 when it deflects to contact the inner side of the guiding frame 8 under the action of the torsion spring 6 is smaller. On the contrary, if the guiding frame 8 is initially more to the right, then the deflection angle of the endoscope 5 is larger. Thus, the deflection angle of the endoscope 5 can be adjusted in advance according to the specific situation of the target position.
[0038] Embodiment 2: On the basis of Embodiment 1, as Figure 8 shown, it further includes a transparent sleeve 14. The sleeve 14 is clamped at the left end of the intubation body 2, and the clamping between the sleeve 14 and the intubation body 2 is a tight-fitting structure, such that a predetermined pushing and pulling force needs to be applied between the two to achieve relative movement. An elastic cloth 15 is fixedly connected to the inner side of the sleeve 14 along the circumference. A glass cover 16 is fixedly connected to the middle of the elastic cloth 15. The glass cover 16 protrudes leftward. The endoscope 5 moves leftward and extends into the glass cover 16. The elastic cloth 15 cooperates with the glass cover 16 to seal the left end of the intubation body 2.
[0039] By providing the glass cover 16, the components inside the intubation body 2 can be protected, achieving a safety protection effect. When the endoscope 5 pops out of the intubation body 2, the endoscope 5 inserts into the glass cover 16, and the glass cover 16 moves synchronously with the endoscope 5, and the elastic cloth 15 undergoes adaptive deformation along with the movement of the endoscope 5 and the glass cover 16.
[0040] Embodiment 3: On the basis of Embodiment 2, as Figure 9 shown, it further includes positioning rods 17 symmetrically distributed before and after the piston frame 101. The positioning rods 17 are slidably connected to the piston frame 101. The outer ends of the positioning rods 17 contact the inner side of the display 1. Positioning holes corresponding to the positioning rods 17 are formed in the inner side of the display 1. When the positioning rods 17 are snapped into the corresponding positioning holes, the endoscope 5 just moves into the glass cover 16. A second spring 18 is fixedly connected between the symmetrically distributed positioning rods 17 before and after.
[0041] When the piston holder 101 is pushed upward, the piston holder 101 drives the positioning rod 17 to move upward. When the positioning rod 17 moves to the positioning hole, the second spring 18 in the compressed state resets and drives the positioning rod 17 to snap into the corresponding positioning hole. At this time, the endoscope 5 just moves into the glass cover 16. If direct viewing is required, the pushing of the piston holder 101 is immediately stopped, and the endoscope 5 will neither deflect nor rotate. If multi-angle viewing is required, the piston holder 101 is continuously pushed upward. When continuing to push upward, the positioning rod 17 needs to overcome the resistance of the display 1. Thus, the present invention only needs to adjust the position of the piston holder 101 according to the demand. During the process of pushing the piston holder 101, through the feeling of being blocked, the state of the endoscope 5 can be easily judged and controlled.
[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claimed rights.
