Description
Technical Field
The invention relates to a disposable endoscope group and an endoscope device, which are suitable for medical equipment such as a large intestine endoscope device or other endoscope devices and have the functions of reducing perforation and damage of an intestinal wall in operation and avoiding the problems of bacterial infection, virus infection and the like caused by repeated use.
Background
Endoscopic devices such as a colonoscope and a gastroscope are medical instruments widely used for examination of the digestive tract of the stomach and intestines of a human body. Taking a colonoscope 70 with a complicated structure as an example, as shown in fig. 11, the colonoscope 70 includes a colonoscope assembly 71 and an operation module 72, the colonoscope assembly 71 has an image capturing unit 711, a steering mechanism 712, a wire 713, a fluid conduit 714 and a solid coating 715 covering the above components, the operation module 72 is connected to the rear end of the colonoscope assembly 71, the operation module 72 has a processing unit, a steering control element 721, a display 722 and the like, the colonoscope 70 can extend into the large intestine of the human body through the colonoscope assembly 71, wherein the large intestine can be expanded by injecting gas into the large intestine through the fluid conduit 714 so that the colonoscope assembly 71 can be pushed in the large intestine. In addition, the image of the inner surface of the intestinal wall of the large intestine is captured by the image capturing unit 711 of the colonoscope assembly 71, the image data obtained by the image capturing unit 711 can be displayed on the display 722 after being processed by the processing unit, and water can be injected into the large intestine through the fluid conduit 714 to clean the intestinal wall, so as to capture the image of the intestinal wall.
In the above-mentioned examination process of the large intestine of the human body using the colonoscope 70, as shown in fig. 11 and 12, since the large intestine 60 of the human body has many bending portions 61, 62, 63, 64, when the colonoscope assembly is inserted into the large intestine of the human body, since the image capturing unit 711, the steering mechanism 712, the lead 713, the fluid conduit 714, etc. in the colonoscope assembly 71 are fixed by the solid coating 715, the bending angle per unit length of the colonoscope assembly 71 is small, and the flexibility is insufficient. In the operation process of extending the colonoscope assembly 71 from the anus of the human body into the rectum and then moving along the intestinal tract of the large intestine, the colonoscope assembly 71 will generate large-force pushing and pressing effects on the intestinal wall of the large intestine, especially when a doctor operates the colonoscope assembly 71 to push towards the turning position or the deep position of the large intestine, so that a lot of technical difficulties and risks of perforation of the intestinal wall exist in the operation process of the colonoscope 70.
According to statistics, the occurrence probability of intestinal wall perforation caused by the colonoscope is about three to five thousandths. Based on the high occurrence probability of perforation of the intestinal wall, how to operate the endoscope device such as a colonoscope to smoothly turn and advance along the bending of the stomach and intestine, and reduce the pushing and pressing on the stomach and intestine is one of the important research and development projects in the technical field of the current endoscope device.
In addition, the conventional endoscopes such as a large intestine endoscope are expensive medical instruments, and cannot be discarded after use in view of medical costs. Taking a colonoscope as an example, the image capturing unit, the steering mechanism, the guide wire, the fluid conduit and the solid coating body coating the above components, which are used in the colonoscope assembly connected to the operation module, are difficult to use in a sterilization kettle at the temperature of 121 ℃ and 1.2kgs/cm2The sterilization procedure was carried out at atmospheric pressure and for a treatment time of 15 minutes. At present, all medical institutions are treated according to procedures such as standard disinfection, sterilization and the like and then are reused. However, the standard disinfection and sterilization procedures described above do not provide for complete sterilization of the colonoscope assembly. That is, even if the used colonoscope assembly is subjected to rigorous multi-standard disinfection and sterilization procedures, the colonoscope assembly cannot be ensured to be in a completely sterilized state. Once bacteria or viruses remain in the colonoscope assembly after the colonoscope assembly is sterilized and disinfected, the examinee who uses the colonoscope is easy to have the risks of bacterial infection, virus infection and the like due to the transfer of the bacteria or viruses.
In the field of medical devices, there are disposable devices, such as needles, to solve the above-mentioned problems of bacterial infection and viral infection. However, in the field of endoscopic devices such as colonoscopes, due to factors such as precision, complexity and reliability of the entire mechanism of the endoscopic device, the conventional endoscopic devices such as colonoscopes are maintained in a reusable manner at high equipment cost, so that the problems of bacterial infection, viral infection and the like caused by the reuse of an endoscopic device cannot be solved during the use of the endoscopic device such as the colonoscope.

In addition, in order to make the image capturing unit 12 capture clear images of the intestinal wall, water can be injected into the large intestine through the conduit 50 to clean the intestinal wall.
Furthermore, during the examination process that the disposable endoscope set 2B is inserted into the large intestine of the patient, the physician may insert a slicing device or other tissue sampling device into the large intestine of the patient through the catheter 50, and the image capturing unit 12 captures the image of the inner surface of the large intestine wall, and the image data obtained by the image capturing unit 12 is displayed on the display 4B, so that the physician can accurately operate the slicing device or tissue sampling device extending out of the front end guide block 11 to perform tissue slicing in the large intestine wall, and then take out the tissue slicing, so as to facilitate the subsequent examination operation of the tissue slice pathology.
In the operation process of examining the large intestine of a patient by the endoscope apparatus, a physician can hold the end portions of the elastic sleeves 30A, 30B, 30C of the disposable endoscope groups 2A, 2B, 2C located outside the anus to push the endoscope toward the anus, and at this time, the elastic sleeves 30A, 30B, 30C have the property of elastic expansion and contraction in the length direction, and flexibly push the front end guide block 11 to advance toward the inner direction of the large intestine in a buffering manner. When the front guide 11 is near the bending portion inside the large intestine, the physician can operate the steering knob 5A of the steering operation assembly 5 to drive the steering member 21 via the control wire set 22 to change the direction of the front guide 11, and then the handheld disposable endoscope set 2A, 2B, 2C is continuously pushed toward the deep part of the large intestine.
In this process, when the physician operates the disposable endoscope sets 2A, 2B, 2C to go deep into the large intestine of the human body for propulsion, the disposable endoscope sets 2A, 2B, 2C can provide proper buffering elasticity for the propulsion force applied when the physician operates the disposable endoscope sets 2A, 2B, 2C through the bending elasticity and the length-direction telescopic elasticity of the elastic sleeves 30A, 30B, 30C, and the soft elastic sleeves 30A, 30B, 30C contact the wall of the large intestine through the soft membrane tube 40, so that the force pushing or pressing the wall of the large intestine can be reduced, and the disposable endoscope sets 2A, 2B, 2C are prevented from excessively pressing the wall of the large intestine.
As can be seen from the above description, the disposable endoscope set and the endoscope device of the present invention are created to provide necessary support for the image capturing module and the steering control module in the endoscope set and provide elasticity with high bending property and stretching deformation, and provide a sterile barrier mechanism by combining the flexible membrane tube to cover the flexible tube and the image capturing module and the steering control module therein, so that the disposable endoscope set has bending deformation capability with a large bending angle, and the disposable endoscope set can be easily controlled to turn and bend and deform with a large bending angle during the operation process of extending into the intestines of the human body, thereby effectively reducing the pushing and pressing on the intestinal wall, reduce the damage to the intestinal wall of the human body.
On the other hand, the elastic sleeve and the membrane tube used by the disposable endoscope set are made of the existing objects which are easy to manufacture and obtain, and the manufacturing cost is low, so compared with the existing high-price endoscope device and the operation cost of disinfection and sterilization after the existing endoscope device is used, the disposable endoscope set has the economic benefit of being immediately discarded after being used, further the problem that the existing endoscope device is easy to cause bacterial or viral infection due to incomplete sterilization is avoided after being repeatedly used, and the subsequent sterilization treatment procedure for the endoscope set can be reduced.
