Description

Technical Field

[0001] The utility model relates to the technical field of colonoscopes, in particular to a disposable soft-tube automatic colonoscope. Background Art

[0002] The colonoscope is the main instrument for examining intestinal diseases. It is a long, thin tube, generally about 1.5 meters long and 15 mm in diameter. During the examination, the colonoscope is pushed into the intestine from the anus, and the intestine is observed using the camera at the front end of the colonoscope. Usually a colonoscope is used repeatedly several times. Although it undergoes complicated disinfection treatments each time, there is still a risk of cross-infection. Furthermore, during a colonoscopy, the colonoscope is pushed into the intestine from the anus. Due to the many bends in the intestine, it is difficult to deliver the colonoscope to the distal end of the intestine by pushing hard at only one point on the outside. Therefore, it will cause great pain to the patient. In addition, since the scope can only be advanced by external thrust at present, the scope tube of the colonoscope can only be made of hard materials, which causes discomfort to the patient. Utility Model Content

[0003] The purpose of the present application is to provide a disposable soft-tube automatic colonoscope to solve the problem mentioned in the above background technology that the existing colonoscope is shared by many people, and although it has undergone complicated disinfection treatment, there is still a risk of cross infection, and the existing colonoscope can only be pushed hard from one point outside the body when inserting the scope, and the intestine has many bends. After the colonoscope has passed through multiple turns, it becomes more difficult to insert the scope, thus causing greater pain to the patient.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a disposable hose automatic enteroscope, which comprises a lens, a peristaltic and steering device, a propulsion device, and a control center in sequence; the peristaltic and steering device comprises a front cylinder fixed to the mirror tube, a rear cylinder slidably sleeved on the mirror tube, and an adjustment body arranged between the front cylinder and the rear cylinder; the lens is detachably connected to the front cylinder; the control center controls the front cylinder and the rear cylinder to be alternately adsorbed on the intestinal cavity and controls the extension and retraction of the adjustment body.

[0005] During the process of inserting the endoscope, in addition to the thrust of the external propulsion device, the front end of the enteroscope inside the intestine also has the traction force brought by the front cylinder. In this way, the endoscope can be inserted smoothly by pulling forward and pushing backward, which greatly reduces the patient's pain. At the same time, due to the traction force of the front cylinder, the material of the endoscope tube does not have to be limited to the hard material in the prior art. The endoscope tube in the utility model can be made of a soft tube, thereby alleviating the patient's discomfort. The control center can receive the image information sent back by the lens, control the front cylinder and the rear cylinder to alternately adsorb on the intestinal cavity and control the expansion and contraction of the regulating body; in addition, the propulsion device can also be controlled to apply thrust to the endoscope tube. The peristaltic and steering device cooperates with the propulsion device under the control of the control center, thereby realizing automatic control of the endoscope tube.

[0006] Preferably, the lens includes a circuit board module integrated with a camera and a light-emitting tube, the circuit board module is sealed in a transparent protective cover, and instrument channels are reserved at the center of the circuit board module and the transparent protective cover; the tail end of the lens is detachably connected to the front barrel. For example, a plug and a lock are provided at the tail end of the lens, and a jack and a keyhole compatible with the plug and the lock are provided at the front end of the front barrel. The lens is installed on the front barrel by combining the plug and the jack, and the lock and the keyhole. The utility model combines a tiny sealed lens and a long lens tube into a separate assembly. When in use, the lens is inserted into the front barrel, and after use, the expensive and easy-to-clean lens is removed, and the cheap and difficult-to-clean lens tube is thrown away, thereby effectively reducing the risk of cross infection.

[0007] Preferably, the front cylinder and the rear cylinder are both formed with an inner cylinder and an outer cylinder to form a cavity, and the cavity is connected to the control center via a trachea; the outer cylinder is provided with a vent hole for connecting the cavity and the intestinal cavity. The inner cylinder of the front cylinder is fixedly sleeved on the outside of the scope tube. The inner cylinder diameter of the rear cylinder is slightly larger than the diameter of the scope tube, so that the rear cylinder can slide smoothly along the scope tube.

[0008] Preferably, the regulating body includes a plurality of bellows arranged between the front cylinder and the rear cylinder, and the bellows are connected to the control center via air pipes, and the control center controls the expansion and contraction of the bellows via the air pipes.

[0009] Furthermore, the regulating body includes three bellows arranged in parallel, and the three bellows are connected to the control center through three air pipes respectively; the three bellows are distributed in an equilateral triangle and a plurality of limit frames are fixed on the outside thereof, and a reserved hole for the mirror tube to pass through is opened in the center of the limit frame. The aperture of the reserved hole is slightly larger than the diameter of the mirror tube so that the limit frame can slide smoothly along the mirror tube. One end of the three air pipes is connected to the bellows, and the other end extends to the inside of the mirror tube through the interface reserved at the front end of the rear cylinder.

[0010] Preferably, the propulsion device comprises a rubber wheel arranged on the mechanical arm, and the rubber wheel holds the mirror tube. The rubber wheel is driven to rotate by a motor, and the motor is controlled by a control center. The propulsion device is near the anus outside the body, and has a propulsion effect on the mirror tube. In the utility model, the control center is connected to the air pipe of the front cylinder, the rear cylinder and the bellows through an air pump. The control center receives the image information sent back by the lens, and controls the forward or backward movement of the mirror tube and the steering of the lens through the air pipe.

[0011] During use, first evacuate the cavity of the rear cylinder so that the outer cylinder of the rear cylinder is adsorbed in the intestinal cavity. Then, inflate the three bellows. The bellows become longer, which will force the front cylinder to move away from the rear cylinder, that is, the front cylinder will pull the scope tube forward. At this time, the propulsion device outside the body will also push the scope tube forward. Then, evacuate the cavity of the front cylinder so that the outer cylinder of the front cylinder is adsorbed in the intestinal cavity. Then, supply air to the rear cylinder to free it from the constraints of the intestinal cavity. Then evacuate the three bellows to shorten them, forcing the rear cylinder to move closer to the front cylinder along the scope tube. Finally, supply air to the front cylinder to free it from the constraints of the intestinal cavity. Then evacuate the cavity of the rear cylinder so that it is adsorbed in the intestinal cavity. At this point, a cycle is completed. If the above cycle continues, the enteroscope will slowly move forward.

[0012] To adjust the direction of the lens, first evacuate the cavity of the rear cylinder to make it adsorbed in the intestinal cavity, and then apply different air pressures to the three bellows. If the lens needs to deviate to the side of bellows A, evacuate bellows A to make it shorter, and at the same time inflate bellows B and C to make them longer, so that the lens will deviate to the side of bellows A. The deflection amplitude depends on the pressure difference between them. The skeleton on the bellows can also limit the deflection amplitude between them, making the deflection uniform; the deflection angle of the lens can exceed 90 degrees in all directions, thereby expanding the field of view of the lens.

[0013] In this way, only a simple device is needed to achieve smooth insertion of the scope and flexible steering of the lens. In addition, the current insertion of the scope is entirely manual, which requires high technical skills of the doctor. However, the utility model patent can completely replace manual insertion of the scope with a machine, which is both accurate and reliable and can improve efficiency.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. In the utility model, the lens and the tube are designed as a split combination structure, so that the lens can be disassembled and cleaned separately after use, and the tube is made of sterile soft material, which is low in cost and can be used once, which significantly reduces the probability of cross infection when the colonoscope is used.

[0016] 2. In the utility model, the control center is used to control the air pump to run according to instructions, so that the front and rear cylinders can be alternately adsorbed in the intestinal cavity, and the three bellows can be adjusted to extend or shorten at the same time. In this way, the front cylinder and the rear cylinder can be alternately advanced or retreated, and during the movement, a pair of rubber wheels on the mechanical arm can be used to apply thrust to the mirror tube to assist the advancement and retreat of the mirror tube, making the movement of the mirror tube smoother.

[0017] 3. In the utility model, the control center is used to control the air pump to run according to instructions, and the air pressure inside the three bellows can be adjusted. By adjusting the difference in the air pressure among the three, the lens can be forced to deflect, thereby increasing the field of view of the lens. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Example: Reference Figure 1-4 The disposable hose automatic enteroscope shown in the figure comprises a lens, a peristaltic and steering device, a propulsion device, and a control center 2 in sequence; the peristaltic and steering device comprises a front cylinder fixed to the mirror tube 1, a rear cylinder slidably sleeved on the mirror tube 1, and an adjustment body arranged between the front cylinder and the rear cylinder; the lens is detachably connected to the front cylinder; the control center controls the front cylinder and the rear cylinder to alternately adsorb on the intestinal cavity and controls the expansion and contraction of the adjustment body. The mirror tube can be made of sterile soft material.

[0026] The lens includes a circuit board module 21 integrated with a camera 26 and a light-emitting tube 25. The circuit board module 21 is sealed in a transparent protective cover 24, and an instrument channel 27 is reserved at the center of the circuit board module 21 and the transparent protective cover 24. A plug 22 and a lock 28 are provided at the rear end of the lens, and a socket 23 and a keyhole that are compatible with the plug 22 and the lock 28 are provided at the front end of the front barrel. The lens is installed at the front end 3 of the front barrel by combining the plug 22 with the socket 23, and the lock 28 with the keyhole.

[0027] Therefore, the lens can be freely loaded and unloaded on the front end 3 of the front barrel, which is convenient for cleaning the lens and replacing the lens tube.

[0028] The front cylinder body is a cavity Ⅰ6 formed by a first inner cylinder 4 and a first outer cylinder 5, and the first inner cylinder 4 is fixed to the mirror tube 1; the cavity Ⅰ6 is connected to one end of the trachea IV7, and the other end of the trachea IV7 extends to the interior of the mirror tube 1 and is connected to the control center 2; the first outer cylinder 5 is provided with a vent 18 for connecting the cavity Ⅰ6 and the intestinal cavity.

[0029] The regulating body includes three bellows arranged in parallel between the front cylinder and the rear cylinder. The three bellows are connected to one end of the three air tubes respectively. The other ends of the three air tubes extend to the inside of the mirror tube 1 through the interface reserved at the front end of the rear cylinder and are connected to the control center 2. The three bellows are distributed in an equilateral triangle and a number of limit frames 19 are fixed on the outside. The center of the limit frame 19 is provided with a reserved hole 20 for the mirror tube 1 to pass through. The aperture of the reserved hole 20 is slightly larger than the diameter of the mirror tube 1, so that the limit frame 19 can slide freely along the mirror tube smoothly. The setting of the limit frame 19 can ensure the stability of the three bellows and the smoothness when turning. The three air tubes are reserved with a certain length outside the mirror tube 1 to prevent the air tube from being over-pulled when the mirror tube 1 moves forward.

[0030] The rear cylinder is formed of a second inner cylinder 8 and a second outer cylinder 9 to form a cavity II10. The diameter of the second inner cylinder 8 is slightly larger than the diameter of the mirror tube 1 so that the rear cylinder can slide smoothly along the mirror tube 1. The cavity II10 is connected to one end of the trachea V11, and the other end of the trachea V11 extends to the inside of the mirror tube 1 and is connected to the control center 2; the second outer cylinder 9 is provided with a vent 18 for connecting the cavity II10 and the intestinal cavity.

[0031] The propulsion device comprises a rubber wheel arranged on the mechanical arm, and the rubber wheel holds the mirror tube 1. The rubber wheel is driven to rotate by a motor, and the motor is controlled by a control center. The propulsion device is near the anus outside the body and applies thrust to the mirror tube.

[0032] When the colonoscope moves forward, the control center 2 controls the air pump to operate according to the command, firstly extracts the air inside the cavity II 10, so that the rear cylinder absorbs the intestinal wall, and then applies the same positive pressure to the bellows A 12, the bellows B 13, and the bellows C 14 at the same time, so that the three extend at the same time, pushing the front cylinder forward, and the mirror tube 1 moves forward with the front cylinder. At the same time, the motor on the robot arm is controlled to rotate forward, so that the rubber wheel holding the mirror tube 1 pushes the mirror tube 1 forward, and the air pump is controlled to extract the air in the cavity I 6, so that the front cylinder The body 5 sucks the intestinal wall, and then air is supplied to the rear cylinder so that the rear cylinder no longer sucks the intestinal wall. Subsequently, the same negative pressure is applied to the bellows A12, the bellows B13, and the bellows C14 at the same time, so that the three are contracted at the same time, driving the rear cylinder forward, and finally air is supplied to the front cylinder so that the front cylinder no longer sucks the intestinal wall. Repeating the above steps, the colonoscope can be advanced by controlling the front cylinder and the rear cylinder to alternately suck the intestinal wall; conversely, the colonoscope can be driven to retreat, so that the advance and retreat of the colonoscope becomes more convenient.

[0033] When the colonoscope is moving, the control center 2 receives the image transmitted by the camera 26. If the lens direction needs to be adjusted, the specific implementation method is: the control center 2 controls the air pump to run according to the instructions, and applies different pressures to the bellows A12, bellows B13, and bellows C14 through the trachea I15, trachea II16, and trachea III17 respectively to deflect the lens in different directions. The pressure difference between them corresponds to the corresponding deflection amplitude, so as to facilitate the movement of the colonoscope; for example: if you want the lens to deflect to the side of bellows A12, air is pumped into bellows A12 to shorten it, and at the same time, bellows B13 and bellows C14 are inflated to lengthen them, so that the camera 26 will deviate to the side of bellows A12, and the deflection amplitude depends on the air pressure difference between bellows A12 and bellows B13 and bellows C14.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
