DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] The embodiment of the present invention provides a visualized gastrointestinal tube anti-blockage cleaning guide wire, comprising a guide wire sleeve 1 and a handle 2;

[0043] Refer to the attached Figures 1 to 4As shown, the length of the guide wire sleeve 1 is greater than the length of the gastrointestinal tube, and the outer diameter of the guide wire sleeve 1 is smaller than the inner diameter of the gastrointestinal tube. The guide wire sleeve 1 is made of a silicone material that can be bent at multiple angles, and the outer surface of the guide wire sleeve 1 is smooth. The guide wire sleeve 1 is provided with a chamber running through both ends, and a traction component 3 is provided in the chamber of the guide wire sleeve 1. The handle 2 is provided at the end of the guide wire sleeve 1, and a control component 4 that can control the traction component 3 to bend is provided inside the handle 2. A suction tube 5 is provided inside the traction component 3, and the front end of the suction tube 5 extends to the front end of the guide wire sleeve 1, and the end of the suction tube 5 passes through the traction component 3 and the guide wire sleeve 1. A miniature camera 11 is provided at the front end of the guide wire sleeve 1, and the miniature camera 11 is equipped with a matching display and power supply equipment, and the miniature camera 11 is electrically connected to the display and the power supply equipment;

[0044] Before use, the end of the suction tube 5 extending from the guide wire sleeve 1 can be connected to the suction port of the negative pressure suction device;

[0045] During cleaning, the front end of the guide wire cannula 1 can be inserted from the end of the gastrointestinal tube outside the patient's body, and the negative pressure suction device can be started when the guide wire cannula 1 is extended into the gastrointestinal tube, so that the front end of the suction tube 5 can absorb and clean the dirt inside the gastrointestinal tube as the guide wire cannula 1 moves. During the cleaning process, the display can be observed to observe the dirt deposition inside the gastrointestinal tube with the help of the micro camera 11;

[0046] When the gastrointestinal tube is inserted into the esophagus through the patient's nasal cavity, the gastrointestinal tube will also be curved due to the curved trajectory from the nasal cavity to the esophagus. In order to smoothly insert the guide wire cannula 1 into the gastrointestinal tube, when the front end of the guide wire cannula 1 is extended to the gastrointestinal tube part inside the patient's nasal cavity, the image transmitted on the display by the micro camera 11 can be used to operate the control component 4 on the handle 2 to control the traction component 3, so that the traction component 3 can drive the guide wire cannula 1 to bend inside the guide wire cannula 1, and continuously push the handle 2 and the guide wire cannula 1 during the operation, so that the guide wire cannula 1 can be gradually extended to the gastrointestinal tube part inside the patient's esophagus along the curved trajectory of the gastrointestinal tube, and the suction tube 5 can clean the dirt inside the gastrointestinal tube through the operation of the negative pressure suction device;

[0047] In clinical applications, the dirt deposits in the gastrointestinal tube can be cleaned without removing the gastrointestinal tube, which can effectively prevent the gastrointestinal tube from being blocked due to the accumulation of drugs or nutrient solution. It can also avoid the pain caused to patients by removing the nasogastric tube, cleaning it, and then reinserting it.

[0048] Preferably, see Attachment Figure 5As shown, the traction assembly 3 is composed of a plurality of traction members 31 arranged in sequence, each traction member 31 is a tubular structure, and the same side ends of every two adjacent traction members 31 are rotatably connected, so that the traction assembly 3 composed of a plurality of traction members 31 can be bent and adjusted in two directions. The end of a traction member 31 closest to the handle 2 in the traction assembly 3 is extended, and the extended end of the end of the traction member 31 at this position is fixedly connected to the front end of the handle 2, the guide wire sleeve 1 is wrapped around the outside of the plurality of traction members 31, and the two ends of the guide wire sleeve 1 are respectively fixedly connected to the outer surfaces of the two traction members 31 at the front end and the end of the traction assembly 3.

[0049] After being combined into one, the plurality of traction members 31 arranged in sequence and rotatably connected can be bent in two directions and form a support inside the guide wire sleeve 1, so that the guide wire sleeve 1 can be adjusted to bend in a C-shaped trajectory, so that after the guide wire sleeve 1 is placed in the gastrointestinal tube and gradually extended, it can be smoothly extended inward along the curved trajectory of the gastrointestinal tube, and the front end of the suction tube 5 can be extended into the gastrointestinal tube in the gastrointestinal part of the patient, and the guide wire sleeve 1 wrapped around the outside of the traction component 3 can protect the traction component 3 and prevent the inside from being invaded by the liquid in the gastrointestinal tube.

[0050] Preferably, see Attachment Figure 5 As shown, the non-connected parts on the same side ends of every two adjacent traction members 31 are provided with oblique cuts 32;

[0051] The oblique cutout 32 provided on each traction member 31 can prevent the two adjacent traction members 31 from colliding with each other at the same side ends corresponding to the rotation direction when they are rotated and adjusted, so that the two adjacent traction members 31 can be rotated and adjusted at a larger angle.

[0052] Preferably, see Attachment Figures 6 to 9 As shown, a clamping block 33 is provided in a traction member 31 at the front end of the traction assembly 3, and the outer wall of the clamping block 33 is fixedly connected to the inner wall of the traction member 31 at that position, and the clamping block 33 is provided with two through grooves 34 for placing the micro camera 11 and the suction tube 5;

[0053] A clamping plate 37 is fixedly disposed in each of the remaining traction members 31 , and the clamping plate 37 is also provided with two through grooves 34 for placing the electrical connection circuit 12 of the micro camera 11 and the suction tube 5 .

[0054] Preferably, see Attachment Figure 8 and 9As shown, two wire passing blocks 35 are symmetrically arranged on both sides of the inner wall of each traction member 31. The two wire passing blocks 35 are staggered at 90 degrees with the adjacent traction members 31 at the rotation connection part in the corresponding traction member 31, and each of the wire passing blocks 35 is provided with a through hole 36.

[0055] Preferably, the control assembly 4 includes a pillar 41, a partition plate 42, two dial wheels 43 and two traction lines 44, the partition plate 42 is vertically arranged inside the handle 2, the two dial wheels 43 are symmetrically arranged on both sides of the partition plate 42 and a certain gap is left between the partition plate 42, and the two dial wheels 43 are concentrically arranged with the partition plate 42, the pillar 41 is horizontally arranged at the center of the partition plate 42 and the two dial wheels 43, the pillar 41 is fixedly connected to the partition plate 42 and the two dial wheels 43, and both ends of the pillar 41 are rotatably connected to the inner wall of the handle 2;

[0056] The ends of the two traction wires 44 are respectively fixedly connected to the two thumbwheels 43 and the pillars 41 at the gaps on both sides of the partition plate 42, and after the two traction wires 44 are respectively reversely wound on the pillars 41 for several turns, the front ends of the two traction wires 44 extend from the handle 2 into the traction assembly 3 from the ends to the front ends, and sequentially penetrate into the through holes 36 on the two wire blocks 35 in the plurality of traction members 31, and then are fixedly connected to the two wire blocks 35 in the frontmost traction member 31 in the traction assembly 3, wherein the penetration tracks of the two traction wires 44 in the traction assembly 3 are both straight tracks;

[0057] Since the gastrointestinal tube is in a curved shape in the nasal cavity and gastrointestinal part of the patient, the guide wire sleeve 1 is not easy to be inserted under normal conditions. Therefore, the operator can hold the handle 2 and turn the two dial wheels 43 by hand to control the rotation of the entire support 41. When the support 41 rotates clockwise, a traction line 44 on the support 41 will be wound around the support 41 and pull a corresponding wire block 35 in the frontmost traction member 31 in the traction assembly 3, and the through holes 36 on the wire blocks 35 corresponding to the traction line 44 in the remaining traction members 31 are The traction wire 44 is provided for shuttling. As the usable length of the traction wire 44 is shortened, the frontmost traction member 31 in the traction assembly 3 gradually rotates in the contraction direction of the traction wire 44 and pulls the remaining traction members 31 to make the entire traction assembly 3 and the guide wire sleeve 1 bend and adjust, so that the guide wire sleeve 1 can be pushed along the curved track of the gastrointestinal tube after the bending adjustment, so that the suction tube 5 can clean the gastrointestinal tube inserted into the gastrointestinal tract of the patient;

[0058] As the traction component 3 bends, a traction line 44 in the reeled state will keep corresponding to the inner arc edge of the traction component 3 in the bent state, while the outer arc edge of the traction component 3 in the bent state will expand due to the angle change, and the other traction line 44 corresponding to the traction line 44 in the reeled state needs to extend its use length due to the bending of the same side of the traction component 3;

[0059] To this end, in the present invention, the winding directions of the two traction wires 44 on the pillars 41 on both sides of the partition plate 42 are set in opposite directions, so that while one traction wire 44 is wound up, the other traction wire 44 can be released synchronously. As the pillar 41 rotates clockwise, the other traction wire 44 originally wound around the pillar 41 for several turns will be gradually released under the rotation drive of the pillar 41, and the usable length of the traction wire 44 will be extended, so that the outer arc edge of the traction component 3 in the bent state will not be blocked by the pulling of the corresponding traction wire 44 and cannot be bent. In clinical applications, it is only necessary to control the dial wheel 43 to rotate clockwise or counterclockwise to control the traction component 3 and the guide wire sleeve 1 to perform unidirectional bending adjustment on both sides, and it can also realize the synchronous operation of retracting and releasing the two traction wires 44, which has the advantage of convenience and speed in operation.

[0060] Preferably, see Attachment Figures 10 to 12 As shown, the handle 2 is provided with slots 21 on both sides corresponding to the partition plate 42 and the two dial wheels 43, and the slots 21 allow the outer sides of the partition plate 42 and the two dial wheels 43 to be exposed from the handle 2;

[0061] By providing slots 21 on both sides of the handle 2 corresponding to the thumbwheel 43, both sides of the thumbwheel 43 can be exposed from the handle 2. In clinical applications, it is convenient for the operator to operate with both hands, making the entire device more flexible in application.

[0062] Preferably, see Attachment Figure 6 As shown, the block 33 is provided with four through slots 34 in total. In addition to the two through slots 34 in which the micro camera 11 and the suction tube 5 are placed, the other two through slots 34 are respectively provided with a micro lighting lamp 13 and a cleaning member 14. The micro lighting lamp 13 is electrically connected to a matching power supply device.

[0063] In order to facilitate the operator to observe the internal conditions of the gastrointestinal tract, a micro-illumination lamp 13 is provided on the card block 33 to provide a light source for the observation image of the micro-camera 11, so that the image can be better transmitted to the display for the operator to observe.

[0064] Preferably, see Attachment Fig.13 and 14As shown, the cleaning member 14 includes a brush 15, a cushion block 16, a traction rod 17 and a cleaning sleeve 18. Each card plate 37 is provided with four through slots 34. In addition to the two through slots 34 for placing the micro camera 11 and the suction tube 5, the other two through slots 34 are used for placing the micro lighting lamp 13 and the power supply device electrical connection line 12 and the cleaning sleeve 18 respectively. The bottom end of the brush 15 is fixedly connected to the cushion block 16. The brush 15 is open to the surroundings in a natural state. The cushion block 16 and the brush 15 can move in the through slot 34 of the card block 33. The cleaning sleeve 18 is arranged in a straight track state through the through slots 34 of multiple card plates 37. The front end of the cleaning sleeve 18 is fixedly connected to the block 33 in the frontmost traction member 31, the traction rod 17 is arranged in the cleaning sleeve 18 and the outer diameter of the traction rod 17 is smaller than the inner diameter of the cleaning sleeve 18, the front end of the traction rod 17 is fixedly connected to the rear end of the cushion block 16, and a control plate 19 is fixedly arranged at the end of the traction rod 17, and a spring 171 is sleeved on the traction rod 17, and the spring 171 is located between the cushion block 16 and the cleaning sleeve 18, and the two ends of the spring 171 are fixedly connected to the cushion block 16 and the cleaning sleeve 18 respectively, and the cushion block 16 and the brush 15 can be pulled toward the cleaning sleeve 18 under the pulling force of the spring 171.

[0065] Preferably, see Attachment Fig.10 and 12 As shown, the control board 19 is arranged in a vertical state in the traction member 31 at the end of the traction assembly 3. The control board 19 can move toward the front end direction in the traction member 31 to drive the brush 15 to extend out from the through groove 34 of the block 33. The traction member 31 and the end of the guide wire sleeve 1 corresponding to the upper and lower ends of the control board 19 are provided with sliding grooves for the two ends of the control board 19 to be exposed. The length of the sliding groove is the same as the movable distance of the control block. The two ends of the control board 19 are respectively passed through the sliding grooves of the corresponding traction member 31, and the two ends of the control board 19 are fixedly provided with sliders 191 that can be pushed by the fingers.

[0066] During the use of the gastrointestinal tube, since the gastrointestinal secretions such as nutrient solution have a certain degree of adhesion, it is difficult to clean the dirt attached to the inner wall of the gastrointestinal tube only by a negative pressure suction device. For this reason, the present invention is provided with a cleaning member 14. When in use, the operator can push the slider 191 to the front end of the guide wire sleeve 1 by hand, so that the slider 191 drives the control board 19 to push the traction rod 17, and push the brush 15 on the cushion block 16 from the through groove 34 of the card block 33 to the outside, so that the brush 15 can extend from the through groove 34 and open around. During operation, the handle 2 and the guide wire sleeve 1 can be slightly pulled or pushed so that the opened brush 15 can clean the inner wall of the gastrointestinal tube, and then the dirt attached to the inner wall of the gastrointestinal tube is cleaned off and adsorbed and cleaned through the suction tube 5.

[0067] Among them, the sliding grooves set on the handle 2 can allow the two ends of the control panel 19 to be exposed. In clinical applications, the sliders 191 set at both ends of the control panel 19 can be operated by the operator's left and right hands, which can effectively improve the flexibility of the entire device when used.
