[0002] An electronic endoscope is a medical device used for endoscopic examination and diagnosis of internal organs or tissues of the human body. It consists of a flexible, bendable long tube and an optical system that can transmit images to a display screen or camera for doctors to observe.

[0003] According to a Chinese patent publication with the patent announcement number CN205612438U, a rigid endoscope that can be equipped with an air-bag-type diagnostic sheath is pointed out; the cited document not only protects the surrounding tissues in the cavity, facilitates the movement of the endoscope in the cavity, but also ensures a clear field of view under the endoscope. In addition, it can be used as an inspection scope; it can also be used with a diagnostic sheath, and general instruments can be inserted to perform surgery. The filled air bag can replace the role of inflation or liquid filling, reducing the occurrence of complications during or after surgery;

[0004] In actual use, although the above-mentioned cited patent has realized the operation mode of replacing liquid filling with airbag, it still has certain limitations in actual use, that is, the hard endoscope in this document lacks a special instrument channel, which means that treatment or sampling tools cannot be directly introduced during endoscopic examination. Operators need to perform treatment or collect tissue samples, and may need to insert other instruments, which increases the complexity and risk of the operation. At the same time, the endoscope in the cited document does not have a flushing channel, which makes the lens and field of view easily interfered by secretions, blood or other substances, affecting the accuracy of observation and diagnosis. At the same time, it is difficult for medical staff to flush the inspection area in time, resulting in reduced inspection accuracy. Therefore, a disposable airbag expansion type electronic hard endoscope is proposed to solve the above problems. Utility Model Content

[0005] In response to one or more of the above defects or improvement needs of the prior art, the utility model provides a disposable balloon-expandable electronic endoscope, which has the advantages of adding a separate instrument channel for better auxiliary inspection and adding a flushing line to facilitate timely flushing of the affected area.

[0006] To achieve the above-mentioned purpose, the utility model provides a disposable balloon dilatation type electronic endoscope, comprising a hollow thin steel tube;

[0007] An instrument channel is inserted into the thin steel tube, and the instrument channel is a thin and long hollow pipe. One end of the instrument channel passes through the thin steel tube and is connected to an instrument channel outlet;

[0008] A flushing outlet pipeline is inserted into the thin steel pipe, and the flushing outlet pipeline is set as a hose and runs along one end of the thin steel pipe to the outlet of the other side of the thin steel pipe. The outlet of the flushing outlet pipeline is connected to a flushing outlet;

[0009] The thin steel tube is externally connected to a second air bag and a first air bag.

[0010] As a further improvement of the present invention, a camera head is embedded in the thin steel tube; a branch is arranged on the side of the thin steel tube; the signal transmission wire of the camera head is integrated in the thin steel tube and extends through the branch to the outside of the thin steel tube and is connected to a data transmission plug.

[0011] As a further improvement of the utility model, the outside of the thin steel tube is connected with a first inflation port and a second inflation port, and the first inflation port and the second inflation port are respectively connected to the first airbag and the second airbag.

[0012] As a further improvement of the present invention, the first inflation port and the second inflation port are both connected with a valve member, and the valve member is used to control the ventilation volume of the first airbag and the second airbag.

[0013] As a further improvement of the present invention, a rubber-coated head is externally sleeved on one end of the branch, and a mounting bayonet is integrally provided on the side of the rubber-coated head.

[0014] As a further improvement of the utility model, the camera head end is a disposable detachable lens, and the camera head end is a high-definition electronic mirror.

[0015] In general, compared with the prior art, the above technical solutions conceived by the utility model have the following beneficial effects:

[0016] In actual use, the disposable balloon-expandable electronic endoscope of the utility model can connect the instrument channel and the instrument channel outlet so that medical staff can insert the medical instrument through the instrument channel and extend it out from the instrument channel outlet. When the camera head is detecting the surgical area, the medical instrument can directly penetrate into the lesion, reducing the risk of secondary operation by medical staff. Compared with the endoscope structure in the cited document, the endoscope of the present application can directly introduce treatment tools or sampling instruments by adding the instrument channel and the instrument channel outlet, so as to perform treatment or collect tissue samples during the endoscopic examination, thereby improving the functionality of the endoscope and enabling the doctor to perform more treatment operations, such as removing diseased tissue, quickly obtaining biopsy samples, etc., thereby improving the accuracy and effectiveness of diagnosis and treatment.

[0017] The disposable balloon-expandable electronic endoscope of the utility model has a connection setting between the flushing port pipeline and the flushing outlet, so that medical staff can pour cleaning liquid into the flushing port pipeline and discharge it through the flushing outlet. Through the connection setting between the flushing outlet and the flushing port pipeline, the cleaning liquid can be finally poured into the operating area and the flushing operation of the operating area can be completed; through the additional flushing port pipeline and flushing outlet, compared with the lens structure in the cited document, through the endoscope structure of the present application, the doctor can introduce appropriate liquid to clean the lens and the field of view, remove the interference of secretions, blood or other substances, maintain the clarity of the field of view of the camera head, and improve the accuracy of observation and diagnosis.

[0029] In this embodiment, compared with the endoscope structure in the cited document, the hard endoscope of the present application, by adding an instrument channel 10 and an instrument channel outlet 14, allows the doctor to directly introduce treatment tools or sampling instruments, so as to perform treatment or collect tissue samples during the endoscopic examination, thereby improving the functionality of the endoscope, enabling the doctor to perform more treatment operations, such as removing diseased tissue, quickly obtaining biopsy samples, etc., thereby improving the accuracy and effectiveness of diagnosis and treatment; through the added flushing port pipeline 9 and flushing outlet 13, compared with the lens structure in the cited document, through the endoscope structure of the present application, the doctor can introduce appropriate liquids to clean the lens and field of view, remove interference from secretions, blood or other substances, maintain the clarity of the field of view of the camera head 1, and improve the accuracy of observation and diagnosis.

[0030] Specifically, refer to Figure 1-4 A camera head end 1 is embedded in the thin steel tube 4; a branch 15 is connected to the side of the thin steel tube 4; a signal transmission wire of the camera head end 1 is integrated in the thin steel tube 4 and extends through the branch 15 to the outside of the thin steel tube 4 and is connected to a data transmission plug 7.

[0031] In this embodiment, in actual use, the camera head 1 can be used to take real-time video of the lesion area, thereby providing the operator with accurate lesion information to facilitate medical staff to treat the patient. The data transmission plug 7 can be used for medical staff to accurately know the current video recording status of the camera head 1 from external instruments. The power connection method between the camera head 1 and the data transmission plug 7 is the existing technology, and the control circuit can be realized through simple programming by technicians in this field. It is common knowledge in this field and is only used without modification, so the control method and circuit connection will not be described in detail.

[0032] Specifically, refer to Figure 1-4 The outside of the thin steel tube 4 is connected with a first inflation port 6 and a second inflation port 11, and the first inflation port 6 and the second inflation port 11 are respectively connected to the first airbag 2 and the second airbag 3.

At this time, the gas source in the gas cylinder can be transmitted to the first airbag 2 and the second airbag 3 through the first inflation port 6 and the second inflation port 11, and the first airbag 2 and the second airbag 3 can be expanded. The first airbag 2 and the second airbag 3 can be set to expand the surgical area during surgery, so that the details of the lesion can be better observed and the surgical site can be observed more clearly.

[0044] Step 2: Through the connection between the flushing port pipeline 9 and the flushing outlet 13, the medical staff can pour the cleaning liquid into the flushing port pipeline 9 and discharge it through the flushing outlet 13. Through the connection between the flushing outlet 13 and the flushing port pipeline 9, the cleaning liquid can be finally poured into the surgical area, and the flushing operation of the surgical area can be completed, and the blood, dirt, etc. of the surgical site can be flushed, thereby improving the accuracy of the medical staff's inspection of the surgical area;

[0045] Step 3: By setting the connection between the instrument channel 10 and the instrument channel outlet 14, in actual use, medical staff can insert the medical device through the instrument channel 10 and extend it from the instrument channel outlet 14. When the camera head 1 is detecting the surgical area, the medical device can directly penetrate the lesion, reducing the risk of secondary operation by medical staff.
