Detailed Description
The following description provides many different embodiments, or examples, for implementing different features of the invention. The particular examples set forth below are illustrative only and are not intended to be limiting.
The disposable endoscope is used as a medical diagnosis instrument, can enter the body, shoots images at a focus through a camera encapsulated at the far end of the endoscope, provides sufficient diagnosis information for doctors to treat diseases, and can effectively avoid cross infection.
A conventional endoscope includes an operation portion (also referred to as a handle) and an insertion portion, and the handle is used to manipulate the insertion portion into a human body. The insertion part can be divided into a module section, a snake bone section, a passive bending section and the like; the insertion portion houses an imaging assembly, an instrument tube, and the like. The endoscope with the integrated structure has a complex structure and is difficult to thoroughly disinfect, so that the endoscope can be completely discarded after being used once to avoid cross infection, the discarding cost is high, great economic pressure is brought to patients, and the endoscope is not favorable for environmental protection. Therefore, the endoscope recycling device has important significance for the research of recycling the endoscope.
In view of the above, an embodiment of the present invention, as shown in fig. 1 and fig. 2, provides an outer sleeve 1, which includes a tube body, one end of which is an insertion port 13, and the other end of which is a lens port 14;
a first channel 11 and a second channel 12 are arranged along the length direction of the tube body, the first channel 11 is used for accommodating an insertion tube 22 of an endoscope, and the second channel 12 is used for accommodating an instrument tube 3;
the first passage 11 and the second passage 12 each communicate with an insertion port 13 and a lens port 14 of the tube.
In the endoscope, the main contaminated parts are parts (called easily contaminated parts for short, such as the instrument tube 3 and the outer wall of the endoscope insertion part) which are in direct contact with the focus, and the other parts (called hardly contaminated parts for short, such as the camera assembly, the handle and the like) which are not in direct contact with the focus can be reused after being subjected to conventional disinfection. In contrast, in the conventional endoscope structure, the easily-polluted part and the not-easily-polluted part are highly integrated and are not easily separated. Therefore, if the easily-polluted parts and the difficultly-polluted parts of the endoscope can be conveniently and rapidly separated, after the endoscope is used, the easily-polluted parts are discarded, and the difficultly-polluted parts are recycled, so that the discarding cost of the endoscope can be greatly reduced.
The outer sleeve 1 in the above scheme can just achieve the above functions. The endoscope partitions easily-polluted parts and parts which are not easily polluted in the endoscope. In particular, the lumen of the overtube 1 is divided into two regions, a first channel 11 and a second channel 12, wherein the first channel 11 is intended to receive an insertion tube 22 of an endoscope and the second channel 12 is intended to receive an instrument tube 3 of an endoscope.
It should be noted that the endoscope in the above-described embodiment has a slightly different structure from the endoscope in the conventional sense. Specifically, the insertion tube 22 of the endoscope in the above-described aspect refers to the remaining portion of the conventional endoscope insertion portion after the instrument tube 3 is removed. I.e. the insertion tube 22 of the endoscope in the above-described solution does not contain the instrument tube 3.
It is understood that the first channel 11 and the second channel 12 in the above-mentioned embodiments may be in a communicating state, that is, the outer sleeve 1 is a large tube, and integrally wraps the insertion tube 22 and the instrument tube 3 of the endoscope, and the first channel 11 and the second channel 12 constitute the inner cavity of the outer sleeve 1; it is also possible to have a non-communicating state, i.e. the first channel 11 and said second channel 12 are two separate channels.
When in use, the outer sleeve 1 is sleeved on the outer sides of the insertion tube 22 and the instrument tube 3 of the endoscope, the insertion tube 22 of the endoscope is separated from the outer sleeve and recycled after use, and the rest parts (including the outer sleeve 1 and the instrument tube 3) are discarded. Therefore, the parts of the endoscope except the instrument tube 3 are recycled, and the disposal cost of the endoscope is greatly reduced.
Preferably, the first channel 11 and the second channel 12 are provided independently of each other.
In the above solution, the first channel 11 and the second channel 12 are independent of each other, which means that the two channels are not communicated with each other.
Although the surgical instrument is introduced into the lesion site through the instrument tube 3 in the second passage 12, it is the inner wall of the instrument tube 3 that is directly contaminated by the surgical instrument. But if a breakage of the wall of the instrument tube 3 occurs, this will result in contamination of the inner wall of the second channel 12. Therefore, by providing the first channel 11 and the second channel 12 independently of each other, it is possible to ensure that the first channel 11 and the insertion tube 22 therein are not contaminated by the lesion even if the second channel 12 is contaminated.
Preferably, the insert port 13 includes a first insert port 131 and a second insert port 132, the first insert port 131 communicating with the first passage 11, and the second insert port 132 communicating with the second passage 12.
In the above-described aspect, in order to further distinguish between the easily-contaminated part (i.e., the instrument tube 3) and the less-contaminated part (i.e., the insertion tube 22) of the endoscope, the insertion ports of the overtube 1 are provided in two, the first insertion port being for insertion of the tube 22 through the endoscope and the second insertion port being for insertion of the instrument tube 3 through the endoscope.
In one embodiment of the present invention, as shown in fig. 6, the cross-section of the first channel 11 is crescent-shaped, and the first channel 11 partially surrounds the second channel 12.
The thinner the endoscope insertion portion (here, the portion of the endoscope insertion tube 22 and the instrument tube 3 which are inserted into the human body as a whole when they are accommodated in the overtube 1), the less the injury and discomfort to the human body when they enter the human body. Thus, as shown in fig. 6, the cross-section of the first channel 11 of the outer sleeve 1 is arranged to be crescent-shaped, and the corresponding cross-section of the insertion tube 22 entering said first channel 11 is also arranged to be crescent-shaped, such that said first channel 11 partly surrounds said second channel 12. Thus, the diameter of the endoscope insertion portion is reduced. The cross-section of the second channel 12 and the instrument tube 3 is not limited and may be circular or other shapes.
As shown in fig. 7, it is of course also possible to make the cross section of the outer sleeve 1 overall oval, wherein the cross section of each of the first channel 11 and the second channel 12 is circular (or square, or other irregular shape), the first channel 11 and the second channel 12 are arranged in sequence along the transverse direction of the cross section of the outer sleeve, and in the longitudinal direction of the cross section of the outer sleeve, the first channel 11 does not form any enclosure for the second channel 12.
Another embodiment of the present invention, as shown in fig. 3 and 4, provides an endoscope including an endoscope main body 2, the above-described overtube 1;
the endoscope body 2 includes a handle 21 and an insertion tube 22, the endoscope body 2 does not include the instrument tube 3;
the insertion tube 22 is received in the first passage 11 of the outer sleeve 1.
It should be noted that the endoscope in the above-described embodiment is slightly different in structure from the endoscope in the conventional sense. Specifically, the insertion tube 22 of the endoscope in the above-described aspect refers to the remaining portion of the conventional endoscope insertion portion after the instrument tube 3 is removed. That is, the insertion tube 22 of the endoscope in the above-described embodiment does not include the instrument tube 3.
In the above scheme, the outer sleeve 1 is sleeved outside the insertion tube 22 of the endoscope, the insertion tube 22 of the endoscope is separated from the outer sleeve and recycled after use, and the rest parts (including the outer sleeve 1 and the instrument tube 3) are discarded. Therefore, other parts of the endoscope except the instrument tube 3 can be recycled, and the disposal cost of the endoscope is greatly reduced.
Further, the endoscope further comprises an instrument tube 3, the instrument tube 3 being arranged independently of the insertion tube 22, the instrument tube 3 being received in the second channel 12 of the outer cannula 1.
