Description

Endoscope host and endoscope device for intelligently detecting organs

The present invention is related to the field of medical endoscopes, and in particular is an endoscope host and internal endoscopes that are suitable for various types of endoscopes and can automatically execute corresponding image detection modes according to various types of endoscopes. Sight glass device.

In some medical departments, endoscopy is used as the diagnosis and treatment method to determine the disease, such as gastroenterology, otolaryngology, obstetrics and gynecology, urology, etc., which are commonly used for examination of organs. However, according to different human body inspection parts, the endoscopic catheter needs to be designed to correspond to the size of the ruler to improve the detection accuracy and safety in use.

The current endoscope device has a "one-to-one" product design for the control host and the endoscope catheter system, which means that the endoscope catheter can only be assembled to the corresponding control host for use. For example, an endoscope for examining the stomach can only be assembled to the gastroscope control host for operation and use. If it is assembled on another control host for other endoscopes, it cannot be driven at all. This is because each endoscope catheter and its corresponding control host are equipped with mutually matched electrical structures. Once the A-type endoscope catheter assembly is set to the B-type control host, the two cannot be matched. Therefore, in the current situation, it is necessary to purchase corresponding control hosts and endoscopic catheters for different organs in various departments, which greatly increases the cost of equipment. For some medical departments, not only a single human body is examined during the diagnosis and treatment process. For example, the gastroenterology department may need to examine the intestine and stomach separately, and the intestine can be divided into duodenum, colon, sigmoid colon, small intestine, or large intestine. Each part has its corresponding inspection endoscope catheter specification. Each of the aforementioned endoscopic catheters must be equipped with a corresponding control host before they can be used, so medical personnel must look for it during the examination The control host corresponding to each endoscope catheter, or the endoscope catheter corresponding to the control host can be assembled and used only after finding the corresponding endoscope catheter, which causes great inconvenience in inspection.

Here, the endoscope main body 1 is described first. The endoscope main body 1 includes a main body 10, a driving electrical connection portion 11, an identification electrical connection portion 12, an organ recognition unit 13 and a processing unit 14. The main body 10 has a connecting channel 101, the outer surface of the main body 10 has a connecting hole 102, and the connecting channel 101 and the connecting hole 102 communicate with each other for inserting an endoscope tube 2 from the connecting hole 102 To the connecting channel 101. Preferably, the main body 10 has a connecting portion, and the connecting channel 101 and the connecting hole 102 are located at the connecting portion, and the connecting channel 101 is correspondingly located inside the main body 10, and the connecting hole 102 is The structural state on the outer surface of the main body 10, and the connecting part can be integrally formed or separable, and when the connecting part is separable, the main body 10 can be provided with a push switch corresponding to the connecting part. Control the fixed state of the connection part. The driving electrical connection portion 11 is disposed in the main body 10 and has a plurality of first electrical connection points 111, and the first electrical connection points 111 are correspondingly located in the connection channel 101. The identification electrical connection portion 12 is arranged in the body 10 and adjacent to the drive electrical connection portion 11, the identification electrical connection portion 12 has a plurality of second electrical connection points 121, and the second electrical connection points 121 correspond to Located in the connecting channel 101, the drive electrical connection portion 11 and the identification electrical connection portion 12 can be formed integrally or separately, for example, the drive electrical connection portion 11 and the identification electrical connection portion 12 are the same The two parts of the substrate, or the drive electrical connection portion 11 and the identification electrical connection portion 12 are respectively different substrates and are arranged adjacent to or adjacent to each other. As shown in Figure 2A, the drive electrical connection portion 11 and the identification electrical connection The parts 12 are two parts of the same circuit board and are arranged adjacent to each other. However, the drawing is only a preferred illustration and does not represent the actual structure. When the endoscope tube 2 is inserted into the connecting channel 101 from the connecting hole 102, the endoscope tube 2 is electrically connected to all the first electrical connection points 111 to generate a driving signal, the The endoscope tube 2 is electrically connected to part or all of the second electrical connection points 121 to generate a type of signal, for example, it is connected to only one of the second electrical connection points 121, or is connected to all of the second electrical connection points 121. The second electrical connection point 121 is turned on. The organ identification unit 13 is arranged in the main body 10 and stores an organ comparison table, the The organ identification unit 13 compares the received type signal with the organ comparison table to determine the type of the organ corresponding to the endoscope tube 2 and outputs an execution signal accordingly. Among them, intelligent detection of organs here refers to the detection of internal organs such as the large intestine, duodenum, colon, sigmoid colon, bronchus, small intestine, ureter, bladder, bronchus, nose, throat, esophagus, gallbladder, stomach, etc. Above. The processing unit 14 is disposed in the main body 10 and is telecommunications connected to the organ identification unit 13 and the identification electrical connection portion 12, so as to display a result image according to the execution signal after receiving the execution signal and the driving signal. That is, after the processing unit 14 receives the execution signal, it can display the name or image of the organ corresponding to the endoscope tube 2, which can be quickly identified when inserted into the body 10 The type of organ corresponding to the sight glass tube 2, for example, when the endoscope tube 2 is a gastric probe tube, the processing unit 14 can display the word "stomach" or a picture after receiving the execution signal. Thereby, through the setting of the identification electrical connection part 12, the type of signal generated according to the conduction status of the second electrical connection points 121 can be generated, and the organ identification unit 13 and the stored organ The comparison table is compared, and then the detection organ corresponding to the inserted endoscope tube 2 is known at this time, and the corresponding result image is displayed through the processing unit 14 to avoid incorrect installation in application This results in delays in inspection operations and inconvenience. As shown in Fig. 1A, it shows that the endoscope main body 1 can be assembled and used with various endoscope tubes 2 and can reliably detect the type of organ corresponding to the endoscope tube 2.

A preferred implementation state is that the number of the first electrical connection points 111 is at least three, and the number of the second electrical connection points 121 is at least four. In this embodiment, the number of the first electrical connection points 111 is at least four. The number of electrical connection points 111 is three, and the number of the second electrical connection points 121 is four as an example, and the first electrical connection points 111 and the second electrical connection points 121 can be elastic The electrical contact structure facilitates the electrical connection with the endoscope tube 2 to enhance the effect of pushing and fixing the endoscope tube 2 through elastic force. A preferred implementation state of the drive signal can be binary and three-bit encoding, and this type of signal is It can correspond to a binary four-bit code, where the code of the drive signal is 111, the code of this type of signal, the bit code corresponding to the second electrical connection point that is in the on state is 1, and the bit code of the second electrical connection point that is not in the on state is 1 The bit code corresponding to the second electrical connection point is 0. That is, when the endoscope tube 2 is inserted into the connecting channel 101 from the connecting hole 102 and is in contact with the driving electrical connection portion 11 and the identification electrical connection portion 12, at least one second electrical connection point 121 is formed In the case of a conductive state, the code is formed according to the arrangement position of the second electrical connection point 121 that is on, for example, the first second electrical connection point 121 and the third second electrical connection point 121 respectively When it is in the conducting state, the output identification signal may be 1010, and the identification signal produced when the first second electrical connection point 121 and the fourth second electrical connection point 121 are respectively in the on state It can be 1001, and the other possible codes are the same as this rule. The organ comparison table contains corresponding plural code data and plural organ data, so that the organ identification unit 13 can read the code of the type signal and compare with the code data to obtain the corresponding The organ data then generates the execution signal. For example, when the code data is 0001, the organ data corresponds to the stomach, and when the code data is 1010, the organ data corresponds to the bronchus, and the organ identification unit 13 is After obtaining the corresponding organ data, the corresponding execution signal can be generated. Of course, in addition to the above-mentioned encoding settings, the drive signal and the discrimination signal can also be set to a binary or more than three-bit encoding, and this type of signal is a binary or more than four-bit encoding.

In a preferred embodiment, the part of the connecting channel 101 corresponding to the driving electric connection portion 11 and the identifying electric connection portion 12 is a half-moon-shaped tubular groove, that is, the connecting channel 101 corresponds to the driving electric connection portion 11 and the identification electrical connection part 12 are open grooves, and the rest are closed tubular structures. Through this structural design, the connecting channel 101 can be inserted into the endoscope tube 2 At this time, an arc-shaped contact area is formed relative to the endoscope tube 2, and the larger the diameter of the endoscope tube 2, the larger the area of the arc-shaped contact area. Accordingly, the half-moon-shaped tubular groove Connect channel 101, the system can be opposite The endoscope tube 2 of various tube diameters achieves the effect of proper pressing and fixing. No matter what the tube diameter of the endoscope tube 2 is, it can achieve an average pressure on the endoscope tube 2 through the half-moon structure. The function of the end avoids the problem of rotation offset after the endoscope tube 2 is inserted, and achieves the positioning effect. As shown in Figure 2C, for example, when the endoscope tube 2 with a larger tube diameter is inserted into the connecting channel 101, the connecting channel 101 is connected to the inner channel 101 in response to the half-moon-shaped tubular groove structure shown on the top side. The mirror tube 2 will form an arc-shaped contact area with a larger area, and it will be pressed against it. The other side of the mirror tube 2 should wait for the first electrical connection point 111 or the second electrical connections. The point 121 forms another direction of pressing and clamping, thereby stabilizing the endoscope tube 2. In Figure 2C, the installation state of the endoscope tube 2 with a smaller tube diameter can also be seen. When the endoscope tube 2 with a smaller tube diameter is inserted into the connecting channel 101, it corresponds to the half-moon tube shape. In a groove structure, the connecting channel 101 and the endoscope tube 2 will form an arc-shaped contact area with a smaller area and press against it, and the first electrical connection points 111 on the other side or the The second electrical connection point 121 will also suppress the endoscope tube 2. It can be seen that the endoscope tube 2 of any tube diameter can be combined with the endoscope main body 1, regardless of If the diameter of the endoscope tube 2 is large or small, it will form an arc-shaped contact area due to the half-moon-shaped structure of the connection channel 101, and will form a pressing and fixing effect according to the first or second electrical connection point. In addition, the identification electrical connection portion 12 further has an identification signal path confirmation key 122. The identification signal path confirmation key 122 is correspondingly located at the end of the connecting channel 101. The identification signal path confirmation key 122 is pressed by the endoscope tube 2 After being pressed and turned on, the first electrical connection points 111 and the second electrical connection points 121 can be electrically connected to the endoscope tube 2. The identification signal path confirmation key 122 may preferably be, for example, a micro switch, so that when the endoscope tube 2 touches the identification signal path confirmation key 122, the conduction is formed in response to the contact action, and the endoscope can be confirmed accordingly. Whether the tube 2 is inserted into the connecting channel 101 from the connecting hole 102 in the correct insertion direction and whether the insertion is correct, to avoid allowing the first electrical connection points when the endoscope tube 2 is not correctly inserted into the connecting channel 101 111 and the second electrical connection points 121 are electrically connected to the endoscope tube 2, resulting in short Circuit phenomenon, causing component damage. Therefore, the identification signal path confirmation key 122 can be used as a fool-proof and positioning structure to prevent the occurrence of dangerous detection situations caused by false detection. For example, if the endoscope tube 2 is not completely inserted into the connecting channel 101 and is misaligned, the endoscope tube 2 will form an electrical connection with the first electrical connection points 111 and the second electrical connection points 121. If it is connected, it may cause coding misjudgment. For example, the endoscope tube 2 was originally a gastroscope corresponding to the stomach, but it was detected as a urethoscope corresponding to the urethra due to the wrong connection. The sight glass tube 2 is applied to the wrong inspection site. For example, in the foregoing example, the inspector may mistakenly apply the gastroscope to the urethral inspection in the case of wrong detection, causing internal organs or organs to rupture and bleeding, or even death. Therefore, in the present invention, the identification signal path confirmation key 122 is provided to make the detection of the endoscope tube 2 more accurate, and to eliminate misjudgments and possible dangerous situations.

In addition, in order to facilitate the viewing of the detection image captured by the endoscope tube 2 after the endoscope main body 1 is activated, the main body 10 further has a display 15 which is telecommunications connected to the processing unit 14 to The image captured by the endoscope tube 2 is displayed.

In addition, the organ identification unit 13 further includes an organ tube identification mode and stores an organ tube comparison table. The organ tube identification unit 13 compares the received type signal with the organ tube comparison table. The comparison is performed to determine the type of organ tube corresponding to the endoscope tube 2 and output an inspection image signal accordingly. The processing unit 14 stores a plurality of endoscopic tube image modes, so that after receiving the inspection image signal, the corresponding endoscopic tube image mode is executed to display the images taken by the endoscopic tube. Among them, the organ tube identification mode can detect at least the large intestine probe tube, duodenal probe tube, colon probe tube, sigmoid colon probe tube, bronchial probe tube, small intestine probe tube, ureter probe tube, bladder probe tube, bronchial probe tube, nose More than two of the detection tube, larynx detection tube, esophagus detection tube, bile detection tube, stomach detection tube, and joint detection tube. Through the organ tube recognition mode, the endoscope main body 1 can directly use the endoscope tube 2 to detect the corresponding organ of the examinee after inserting any type of the endoscope tube 2 Karma not only informs the type of endoscope tube 2, but can further achieve the effect of "one host is suitable for multiple endoscope tubes". Wherein, the execution of the organ tube recognition mode can be operated simultaneously with the aforementioned mode of recognizing the organ and generating the result image. In other words, the user can make the endoscope main body 1 in the inner view through a switching action. After the mirror tube 2 is inserted from the connecting hole 102 and electrically connected to the drive electrical connection portion 11 and the identification electrical connection portion 12, the organ identification unit 13 only adds the type signal to the organ comparison table Compare, or only compare the category signal with the organ tube comparison table, or enable the organ identification unit 13 to simultaneously compare the category signal with the organ comparison table and the organ tube The tables are all compared, so that the endoscope main body 1 can not only distinguish the organ type of the endoscope tube 2, but also directly match each endoscope tube 2 for direct application.

Preferably, the endoscopic imaging modes are gastroscopic imaging mode, duodenoscope imaging mode, colonoscopy imaging mode, sigmoidoscopy imaging mode, colonoscopy imaging mode, bronchoscopy imaging mode, ureteroscopy imaging mode, cystoscopy imaging Mode, rhino-laryngoscope image mode, thoracoscope image mode, laryngoscope image mode, choledochoscopy image mode, arthroscopic image mode, colposcopy image mode, enteroscopy image mode, otoscope image mode, laparoscopic image mode, etc. , So that the endoscope main body 1 can be applied to most common types of endoscope examination and diagnosis, and can be driven and used with various types of endoscope tubes 2.

More specifically, a preferred setting state enables the organ identification unit 13 to store a clear image parameter corresponding to the type of organ tube corresponding to the endoscope tube, wherein when the endoscope tube is used for joint inspection, the The image clarity parameter is between 5~35mm; when applied to stomach examination, the image clarity parameter is between 5~100mm; when applied to vaginal examination, the image clarity parameter is between 15~50mm; when applied to bronchial and bladder examination, the image clarity parameter is between 5~100mm. It is between 3~50mm; when used in colorectal examination, the image clarity parameter is between 2~100mm; when used in abdominal cavity examination, the image clarity parameter is between 15~120mm and applied The image clarity parameter during duodenal examination is between 4 and 90 mm. Thereby, when any type of the endoscope tube 2 is inserted into the main body 10, the corresponding organ can be determined through the organ identification unit 13, and at the same time, it can be detected in response to the imaging needs of the organ. The image clarity parameter is formulated so that when the endoscope tube 2 performs a detection operation through the endoscope main body 1, it can be adjusted according to the aforementioned parameter range so that the endoscope tube 2 can shoot to obtain a clear detection image. In addition, the organ identification unit 13 may further store a micro imaging parameter, and the micro imaging parameter is preferably between 1 mm and 5 mm. Here again, the identification signal path confirmation key 122 mentioned above can effectively prevent misidentification. When the identification accuracy is improved, it can also prevent adjustment to the wrong image clarity parameters, which will make the inspection image too blurry.

The endoscope tube 2 can perform imaging inspections on various organs of the human body, and also It can be used as an auxiliary tool for nasogastric tube replacement. The diameter of the nasogastric tube commonly used today is about 2mm~5.5m. When the diameter of the endoscope tube 2 is 2~5mm, the endoscope can be used. The hardness of the tube 2 is between Shore (Shore) 50~80A. At this time, the endoscope tube 2 can be used for nasal and throat inspection, and the endoscope tube 2 is also provided for guiding and replacing the nasogastric tube. The sight glass tube 2 is inserted into the nasogastric tube from the exposed end 90 of the nasogastric tube that has been placed in the human body, and extends to the end 91 of the nasogastric tube placed in the human stomach, so that the nasogastric tube runs along the inner The endoscope tube 2 is drawn out, and another nasogastric tube is sheathed by the connecting end 21 of the endoscope tube 2, and the nasogastric tube is inserted along the endoscope tube 2 to be positioned inside the human body. Among them, in order to have both the inspection function of the endoscope tube and the guiding performance relative to the nasogastric tube, the hardness of the endoscope tube 2 can be limited to Shore (Shore) 50~80A to facilitate penetration Inside the human body, it will not be too soft to make the nasogastric tube difficult to move along it. Of course, if the aforementioned endoscope tube 2 is to be used to replace the nasogastric tube, the suitable endoscope tube 2 is selected within the aforementioned diameter range according to the diameter of the nasogastric tube.

As shown in Figure 9, when the human body has a nasogastric tube, the endoscope tube 2 can enter the nasogastric tube from the exposed end 90 of the nasogastric tube, and then proceed along the nasogastric tube until it enters the stomach. At this time, the endoscope tube 2 and the endoscope main body 1 can maintain electrical communication, and since the nasogastric tube is made of transparent material Therefore, the state of the nose, esophagus, and stomach can still be observed with the endoscope tube 2. When the nasogastric tube is to be replaced, the connecting end 21 of the endoscope tube 2 is removed from the connecting hole 102. At this time, the nasogastric tube placed in the human body can be moved along the endoscope tube 2 Pull out, as shown in Figure 10. After removing the original nasogastric tube, as shown in Figure 11, a new nasogastric tube can be sleeved outside the endoscope tube 2 from the connecting end 21, and the nasogastric tube can be placed along the The endoscope tube 2 is inserted and positioned inside the human body to complete the replacement of the nasogastric tube. And after the nasogastric tube is inserted into the required length, the connecting end 21 of the endoscope tube 2 can be inserted back into the connecting hole 102, and then image capture inspection can be performed to confirm the status of the nasogastric tube, and then The endoscope tube 2 is slowly moved away from the human body to assist in completing the nasogastric tube placement operation. In addition, when the first electrical connection points 111, the second electrical connection points 121, the third electrical connection points 211, and the fourth electrical connection point 212 are arranged in a straight line, it is easier to cuff the nasogastric tube Insert the endoscope tube 2 and slide to the nasal cavity, esophagus and stomach.

More specifically, in practice, when a new nasogastric tube is placed, there is a certain probability that the nasogastric tube will be misplaced. For example, after the nasogastric tube enters from the nose, it extends into the trachea instead of the esophagus. If the follow-up feeding action is not detected in time, the person will be in serious fatal danger. Therefore, in the past, after the nasogastric tube was placed, it was necessary to take a chest X-ray to confirm the position of the nasogastric tube. However, this method requires one more inspection procedure, and most of it needs to be moved to the X-ray laboratory to be able to The shooting was completed, which caused many inconveniences. In view of this, the inventor of the present invention conceived that the endoscopic tube 2 can be used as a guiding tool for nasogastric tube placement while having inspection functions, thereby greatly improving the accuracy of nasogastric tube placement. , Safety and speed, and there is no need to confirm the position of the nasogastric tube through X-ray after placement.

In summary, the endoscope main body 1 and the endoscope device 3 of the present invention use the electrical conduction state to detect the type of endoscope corresponding to the inserted endoscope tube 2 to achieve " Insert the endoscope tube to know what kind of organ is used", and can further automatically switch and execute the corresponding image mode for the inspection personnel to control and use, and has the pole of "one host can handle multiple endoscope tubes" Good application effect, From the standpoint of host design, it is no longer necessary to develop and design corresponding electrical structures for various endoscope tubes one by one. From the standpoint of users, the machine purchase cost can be greatly reduced.

However, the above are only preferred embodiments of the present invention, and are not used to limit the scope of implementation of the present invention; therefore, equal changes and modifications made without departing from the scope of the present invention should be covered by the present invention Within the scope of the patent.
