Description

Technical Field

[0001] The present invention belongs to the field of medical devices and relates to a new type of electronic endoscope and a connection and use method thereof. Background Art

[0002] Electronic endoscopes have been widely used in the medical field and have become an important tool in medical work; their high cost and high disinfection requirements have hindered their popularization, especially in the downward direction. In an environment where medical resources are scarce, it is very necessary for medical resources to sink. A core of the sinking of medical resources is that technologies that are easy to use and can be popularized can sink. As an important tool for medical diagnosis and treatment technology, most of the current electronic endoscopes that can perform liquid injection, liquid injection and aspiration functions have relatively complex structures and uses, difficult operation, are quite bulky, and have high purchase and maintenance costs. Of course, there are also problems caused by the disinfection of medical electronic endoscopes, resulting in cross-contamination. The present invention provides a new type of electronic endoscope and a connection and use method thereof, which optimize the traditional structure as much as possible to make it more portable and compact, easy to operate, reduce the purchase and maintenance costs, and provide simple disinfection to meet the requirements for reusing medical devices. Summary of the Invention

[0003] The purpose of the present invention is to design a new type of electronic endoscope and a connection and use method thereof to solve the problems of complex structure and use, difficult operation, cost and disinfection as much as possible.

[0005] The mirror body part is inserted into the proximal end of the catheter flush with the distal opening of the catheter or the distal end of the mirror body part remains inside the distal opening of the catheter, or it can also extend out of the distal opening of the catheter.

[0006] The catheter adopts at least a single cavity and multi-head opening design, or a multi-cavity and multi-head opening design, and is used as an aspiration, liquid injection, air injection and instrument channel.

[0007] A flexible spring is provided at the distal end of the catheter to change the directions of aspiration, liquid injection, air injection and instruments.

[0008] The catheter is outside the mirror body part and is inserted from the distal end of the mirror body part and connected to the operation part in a freely detachable connection manner; the catheter is non-fixed to the operation part and the mirror body part and is freely detachably connected together; the operation part and the mirror body part are fixedly connected together with glue in a completely sealed structure.

[0009] The catheter, the operation part and the mirror body part fixed together with glue can be used independently or simultaneously.

[0010] The outside of the operation part is provided with an endoscope liquid-gas valve button, a photographing button, a video recording button, a freezing button and a control knob.

[0011] There are two control knobs, which are respectively arranged on both sides of the operation part. Each control knob is used to control two directions of the mirror body of the mirror body part, and the two control knobs are used to control four directions of the mirror body of the mirror body part.

[0012] The number of the endoscope liquid-gas valve buttons is at most 1. The endoscope liquid-gas valve button mainly includes a T-shaped cap, a fixing device, a spring, a push rod core and a metal outer tube. A spring is arranged between the T-shaped cap and the fixing device. The push rod core is provided with at least 5 interfaces (a, b, d, e, j) and a plurality of sealing rings, and two of the interfaces (d, e) can communicate with the external environment.

[0014] The metal outer tube is provided with at least 4 interfaces (h, c, f, g), three of which (h, c, f) are connected to the pipeline, and 1 interface (g) can communicate with the human body, and finally the functions of sucking, inflating and injecting liquid into the human body can be realized.

[0015] The inside of the operation part is provided with a knob rotation mechanism, a photographing / video recording / freezing function board and some pipelines.

[0016] The number of the knob rotation mechanisms is two sets, which are fixed side by side inside the operation part. Each knob rotation mechanism is correspondingly connected to a control knob for controlling the direction of the mirror body of the mirror body part.

[0017] The operation part is also provided with an interface L, which can be connected to the external catheter or the internal pipeline to realize the functions of sucking, inflating and injecting liquid into the human body.

A light source and a camera for connecting to an image processing display screen are provided at the distal end of the mirror body part. Compared with the existing electronic endoscope where the catheter is inside the electronic endoscope, it is more convenient for medical staff to disassemble, clean, disinfect and perform daily maintenance, and the structure is also simpler.

[0021] For the novel electronic endoscope and its connection and use method of the present invention, dual control knobs are respectively arranged on both sides of the operating part, and four directions can be adjusted, which is more flexible than the existing single control knob that can adjust two directions. And compared with the existing dual control knobs on the same side of the operating part, the operating parts on both sides can be smaller, more convenient for finger operation, and more labor-saving in operation.

[0022] For the novel electronic endoscope and its connection and use method of the present invention, only one liquid-gas valve button for a single endoscope is required to have at least one port communicating with the human body to at least solve the problems of liquid injection, gas injection and suction. Compared with the existing situation where at least two valve buttons and two ports communicating with the human body are required to solve the problems, the structure is simpler, and the misoperation caused by switching between buttons is reduced.

[0023] For the novel electronic endoscope and its connection and use method of the present invention, the operating part and the connecting part are connected in a freely detachable manner, which is convenient for future use and maintenance and reduces the use and maintenance costs.
