Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an endoscope with a detachable working channel. Background Technique

[0002] An endoscope is a medical device that enters the human body through a natural cavity for observation, biopsy sampling, diagnosis and treatment. The endoscope often has a working channel built-in. By inserting biopsy sampling accessories through the working channel, it can assist in detecting early lesions, accurately and quickly diagnosing diseases. And by inserting treatment instruments such as ablation probes through the working channel, minimally invasive surgeries in the body such as tumor treatment can be carried out. It is applicable to the diagnosis and treatment operations of hollow organs such as the bronchus, digestive tract, and urinary tract.

[0003] Currently, when using an endoscope, the following problems will occur:

[0004] Since the working channel is built inside the endoscope, its inner diameter is restricted by the overall size of the endoscope, and it often cannot meet the clinical needs. In addition, due to its product structure, it is difficult to thoroughly clean and disinfect the inner wall of the working channel, posing a risk of nosocomial cross-infection; and the cleaning and disinfection work after use is complex, takes a long time, has a huge workload, and there is a risk of insufficient disinfection. Moreover, the disinfection cycle is long after the product is used, resulting in limited usage frequency of the equipment and increasing the requirement for the number of equipment. Because endoscopes are expensive, the number purchased by hospitals often cannot fully meet the clinical diagnosis and treatment needs, which not only increases the work burden and labor intensity of medical staff, but also leads to inadequate clinical disinfection work, posing a greater potential safety hazard.

[0005] The utility model aims at the above problems and provides an endoscope with a detachable working channel. Summary of the Utility Model

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0035] As Figure 1-8 shown, an endoscope with a detachable working channel includes a disposable component 1 and a control device 2. The disposable component 1 includes a connecting portion 11, a working end portion 12, and a suction component 13. One end of the suction component 13 is fixedly connected to the connecting portion 11, and the other end is detachably connected to the control device 2. One end of the working end portion 12 is fixedly connected to the connecting portion 11. The control device 2 includes a mounting end portion 21 and a lens assembly 23. The mounting end portion 21 is detachably connected to the connecting portion 11. The lens assembly 23 passes through the connecting portion 11 and enters the interior of the working end portion 12. The endoscope is divided into a disposable component 1 for single use and a control device 2 that can be used multiple times. After endoscope examination, the disposable component 1 is directly discarded, and the outer wall of the control device 2 is disinfected, shortening the time required for disinfection and sterilization, reducing the difficulty of disinfection and sterilization work, and reducing the risk of insufficient disinfection.

[0036] The interior of the working end portion 12 is provided with a single channel. During the operation of the endoscope, the lens assembly 23 reaches the patient's body through the channel, the surgical instrument reaches the affected area through the gap between the lens assembly 23 and the inner wall of the channel, and the negative pressure device sucks the liquid at the front end of the working end portion 12 through the gap between the lens assembly 23 and the inner wall of the channel.

[0037] In some embodiments of the present application, as Figure 1-8 shown, the disposable component 1 further includes a limiting structure 112. The limiting structure 112 is fixedly connected to the connecting portion 11. A limiting block 212 is provided on the side wall of the mounting end portion 21. The limiting structure 112 is adapted to the limiting block 212. When the disposable component 1 is spliced with the control device 2, the limiting structure 112 abuts against the limiting block 212 to prevent the control device 2 from detaching from the disposable component 1. After the endoscope operation is completed, the limiting structure 112 is toggled to make the limiting block 212 disengage from the limiting structure 112, and then the control device 2 can be detached from the disposable component 1.

[0038] Furthermore, a guiding surface 211 is provided on the side wall of the mounting end portion 21. The purpose of the guiding surface 211 is:

[0039] 1. To guide the splicing direction of the disposable component 1 and the control device 2 and prevent incorrect splicing;

[0040] 2. To prevent relative rotation between the control device 2 and the disposable component 1.

[0041] In the exemplary embodiment of the present application, as Figure 1-8 shown, a sealing structure 14 is provided inside the connecting portion 11; one end of the sealing structure 14 abuts against the connecting portion 11, and the other end abuts against the control device 2. The purpose of the sealing structure 14 is to increase the sealing performance when the disposable component 1 is spliced with the control device 2, prevent the patient's body fluid from flowing out through the gap between the disposable component 1 and the control device 2, and also prevent the negative pressure from acting on the gap between the disposable component 1 and the control device 2, resulting in difficulty in sucking the liquid at the front end of the working end 12.

[0042] Specifically, a working port 111 is provided on the connecting portion 11; the working port 111 is communicated with the working end 12. The surgical instrument is inserted into the inside of the working end 12 through the working port 111 and reaches the affected area under the guidance of the working end 12.

[0043] Furthermore, a negative pressure port 113 is provided on the connecting portion 11; one end of the suction assembly 13 is fixedly connected to the negative pressure port 113; the negative pressure port 113 is communicated with the working end 12. The suction assembly 13 is communicated with the working end 12 through the negative pressure port 113, so as to suck the liquid at the front end of the working end 12.

[0044] In some examples of the present application, as Figure 1-8 shown, the control device 2 further includes a control end 22; the control end 22 is fixedly connected to the mounting end 21; the suction assembly 13 is detachably connected to the control end 22. An installation position 221 is provided on the control end, and the suction assembly 13 is installed inside the installation position 221 during use to facilitate the opening and closing of the negative pressure control.

[0045] Preferably, a connection port 222 is provided on the side wall of the control end 22, and the function of the connection port 222 is to connect to an external computer to observe the image captured by the lens assembly 23.

[0046] Specifically, the suction assembly 13 includes a rigid tube 131, a connecting tube 132 and a controller 133; the controller 133 is located inside the rigid tube 131; one end of the connecting tube 132 is fixedly connected to the connecting portion 11, and the other end is fixedly connected to the rigid tube 131; the rigid tube 131 is detachably connected to the control device 2.

[0047] The rigid tube 131 is detachably connected to the installation position 221. The function of the controller 133 is to control the connection and closure of the internal pipeline of the rigid tube 131, thereby controlling the opening and closing of the negative pressure.

[0048] A joint is provided at one end of the rigid tube 131 away from the connecting tube 132. The function of the joint is to connect to an external negative pressure suction device.

[0049] In a specific example of the present application, a pre-bending section 121 is provided inside the working end 12. The purpose of the pre-bending section 121 is to facilitate the control of the bending of the working end 12 by the lens assembly 23 so as to enter the correct internal part of the human body. If the pre-bending section 121 is not provided inside the working end 12, since the outer diameter of the working end 12 is larger than the outer diameter of the lens assembly 23, the working end 12 cannot fully follow the bending of the lens assembly 23, and it is difficult to control the orientation of the distal end of the working end 12.
