Description

Technical Field

[0001] The present application belongs to the technical field of medical devices, and specifically relates to an endoscope with multiple operation channels. Background Art

[0002] Electronic bronchoscopy is an endoscopic examination that inserts the endoscope into the patient's trachea, bronchi and more distal ends to directly observe tracheal, bronchial and lung lesions. At the same time, pathological tissues can be removed, cells or secretions can be brushed out, or lavage fluid can be collected for testing to obtain cytology, bacteriology and pathological histology test results, providing a reliable basis for clinical diagnosis.

[0003] Currently, when electronic bronchoscopes are used for biopsy sampling in clinical practice, the biopsy instrument is placed into the only biopsy channel for sampling. The operation of a single instrument has limitations and inconveniences. If flushing or hemostasis is required during the biopsy, the biopsy instrument needs to be taken out and a new flusher or hemostat needs to be inserted. This operation is cumbersome and cannot be performed in time, and there are certain risks. Utility Model Content

[0034] Example 1

[0035] A specific embodiment of the utility model is as follows Figures 1 to 6 As shown, an endoscope with multiple operation channels is disclosed, including a handle portion 100, one end of the handle portion 100 is connected to an operation portion 200, and the other end is connected to an insertion portion 300: the handle portion 100 is provided with multiple operation channels for various instruments to enter; the operation channels extend to the front end of the insertion portion 300; the operation portion 200 is provided with a suction port 201, and multiple suction channels are connected in the suction port 201, and the suction channels are connected to the operation channels one by one.

[0036] That is to say, the handle portion 100 is provided with at least two operation entrances, each of which has an operation channel extending into the interior of the endoscope, and the operation channel extends all the way to the front end of the endoscope insertion portion 300. The operation entrance and the operation channel can be used for entry of instruments such as biopsy, flushing, and hemostasis; each operation channel is connected to a suction channel.

[0037] In this embodiment, the operating part 200 is provided with a suction port 201, the outer end of the suction port 201 is connected to the suction device, a plurality of through holes are provided on the inner end side wall of the suction port 201, the number of the through holes is the same as the number of the suction channel, and the through holes on the inner end side wall of the suction port 201 are connected to the inlet of the suction channel. Optionally, the through holes on the inner end side wall of the suction port are the inlet of the suction channel, and the suction port and the suction channel are integrally formed.

[0038] In this embodiment, the connection between the suction port 201 and the suction channel is an inverted conical groove. By setting the interior of the suction port 201 as an inverted conical groove, it is convenient for the cleaning brush to enter for cleaning. A plurality of through holes on the inner end side wall of the suction port 201 are provided on the side wall of the inverted conical groove and are arranged around the axis of the inverted conical groove.

[0039] Exemplarily, the endoscope with multiple operating channels in this embodiment has two suction channels and two operating channels. Specifically, the suction channel has a first suction channel 202 and a second suction channel 203, and the operating channel has a first operating channel 101 and a second operating channel 102; wherein the first suction channel 202 is connected to the first operating channel 101, and the second suction channel 203 is connected to the second operating channel 102.

[0040] In one optional embodiment, a transfer tube is provided in the middle of the suction channel, and the diameter of the transfer tube is smaller than the diameters of the two ends of the suction channel. Figure 5 As shown, the middle of the first suction channel 202 has a first transfer tube 2021, and the middle of the second suction channel 203 has a second transfer tube 2031. The first transfer tube 2021 and the second transfer tube 2031 have thinner diameters, which can make the overall structure of the endoscope more compact.

[0041] In this embodiment, the operating entrance of the operating channel is detachably provided with a sealing member 103. Figures 6 to 8 As shown, the sealing member 103 has a seat body 1031 and a cover body 1032. The seat body 1031 has a hollow channel that is set through. The seat body 1031 is sealed and sleeved at the operation entrance of the operation channel. The hollow channel of the seat body 1031 is sleeved outside the operation entrance and is in sealing contact with the outer wall of the operation entrance. The cover body 1032 is connected to the seat body 1031 through a flexible member 1033, and can be detachably installed at the opening of the seat body 1031 to seal the opening of the seat body 1031.

[0042] Furthermore, an elastic sealing sheet 1034 is provided in the hollow channel of the seat body 1031, and an entrance for the instrument to enter is provided on the elastic sealing sheet 1034, and the entrance is a small slit, and the size of the entrance is smaller than the outer diameter of the instrument. The elastic sealing sheet 1034 is arranged perpendicular to the axis of the hollow channel. Since the size of the entrance is smaller than the outer diameter of the instrument, when the instrument is inserted into the slit of the elastic sealing sheet, the slit opens, so that the elastic sealing sheet is close to the outer wall of the instrument, forming a closed environment.

[0043] In this embodiment, the endoscope with multiple operation channels further includes an external camera system 400, which is connected to the operation unit 200. The external camera system 400 has image adjustment and target recognition functions, and the image adjustment includes color, brightness adjustment, contrast, and clarity adjustment.

[0044] The use process of the endoscope with multiple operation channels in this embodiment is as follows: the endoscope is placed in the human body. After reaching the target position, the suction port 201 is connected to an external suction device, and the supporting instruments such as biopsy and flushing are respectively placed in the scope body from the two operation channels until the front end of the endoscope insertion part 300. The instrument can perform a biopsy operation in the human body. The liquid and dirt generated during the operation can be quickly removed by pressing the suction button to activate the suction function to keep the field of vision clear. Since the operation channel port is blocked, the suction liquid will not splash out from the channel port, and it will be sucked all the way to the suction pump connected to the suction port 201. Multiple biopsy instruments can be used to suck liquid while performing sampling operations in the body to ensure a clear field of vision. When only a single instrument needs to be operated, the remaining operation channel entrances are sealed with a seal 103.

[0045] Compared with the prior art, the endoscope with multiple operating channels provided in this embodiment has a multi-branched suction channel at the suction port, and the multiple operating channels are all connected to the suction channel, which increases the suction area and improves the suction efficiency, thereby realizing the simultaneous operation of multiple instruments, greatly improving the operating efficiency and safety, and overcoming the limitations and inconveniences of the existing endoscope that can only operate a single instrument.

[0046] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above description is only the specific implementation method of the present application and is not intended to limit the scope of protection of the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
