Referring to Fig. 1, Fig. 3 and Fig. 6, the manufacturing method of the tip according to the embodiment of the present invention includes the following steps:

The manufacturing step of the casing 100 is that the casing 100 is injection molded, and one end surface of the casing 100 is divided into two surfaces with a height difference, the two surfaces are respectively a first plane 101 and a second plane 102, and the first plane 101 is higher than the second plane 102 , the first mounting hole 110 is disposed on the first plane 101 , and the second mounting hole 120 is disposed on the second plane 102 . The shell 100 is the shell 100 of the tip, which is the basic carrier for installing and fixing other parts on the tip, and can also be called the tip frame; the shell 100 is roughly cylindrical; one end surface of the shell 100 is the outer surface of the shell 100. The end surface of one end of the endoscope (or the end away from the endoscope insertion part), and the other end of the housing 100 is the part connected to the endoscope insertion part (or the end close to the endoscope insertion part); therefore, the housing 100 One end face of the endoscope is the side that contacts and is adhered to body fluids when the endoscope is actually used. It should be understood that the height measurement in the present utility model takes the reference axis as the measurement reference, and the direction from the other end of the housing 100 to one end of the housing 100 is the upward direction (for example, at a certain point on the housing 100, the distance from the other end of the housing 100 The farther the distance at one end, the higher the height of the point); specifically, the reference axis is regarded as the measurement side of the ruler, and the height of any point on the object is measured, a plane is perpendicular to the reference axis, and the above-mentioned point on the object is at On the above-mentioned plane, the scale value at the intersection of the above-mentioned plane and the reference axis is the height value of the point. What needs to be understood is that the first plane 101, the second plane 102, and the third inclined plane 103 are all a certain surface on an actual object, that is, a limited area, an actual surface, and the concept of an infinitely sized plane in mathematics Different, in the same way, the first plane 101, the second plane 102, and the third inclined plane 103 can be planes or curved surfaces with a slight curvature; while the first plane and the second plane have a height difference, the first plane 101 higher than the second plane 102, that is, the lowest point on the first plane 101 is also higher than the highest point on the second plane 102, and therefore, it does not mean that the first plane and the second plane are absolutely parallel, the first plane and the second plane They may be parallel or not; in this embodiment, both the first surface and the second surface are planes, both are parallel, and both are perpendicular to the reference axis. There is a mounting hole on the surface. It can also be said that the end surface of one end of the mounting hole is on this surface; it also needs to be understood that since it is a hole, it is a structure that is concave inward on the opposite end surface, that is, the top surface of the hole is on the end surface. , while the bottom of the hole is lower. It should be understood that the installation holes in the present invention are not necessarily circular holes, but also irregular-shaped holes such as square holes, semicircular holes, triangular holes, or even a combination of holes of various shapes.

In the first installation step, the camera 200 is installed in the first installation hole 110 , and the mirror surface 210 of the camera 200 is coplanar with the first plane 101 . Camera 200 is a commonly used part in the endoscope field. In the present embodiment, camera 200 includes a CCD chip, a lens, a wire and a protective cover, and the miniature CCD chip and the wire are connected by welding, and are fixedly installed in the protective cover inside by insulating glue , and then the lens is electrically connected to the micro CCD chip for acquiring image signals and transmitting the image signals to the image processing module; the camera head 200 can also be other existing imaging elements. The mirror surface 210 of the camera 200 is the end surface of the end of the camera 200 facing the outside; when the endoscope is actually used, the mirror surface 210 is a window for receiving external information, and it is also the side of the camera 200 that contacts and is adhered to body fluids. The camera 200 is installed in the first installation hole 110; specifically, the camera 200 is put into the first installation hole 110, so that it is positioned and limited by the first limiting structure (and at this time, the mirror surface 210 and the first plane 101 Exactly coplanar), then the gap between the camera 200 and the housing 100 can be filled with glue, and the camera 200 is fixed in the first installation hole 110, and after the glue fills the gap, it also prevents external objects (such as body fluids, disinfectant, etc.) It enters the inside of the shell 100 through the gap, pollutes and damages the components on the tip, and even causes cross-infection. Coplanar, it needs to be understood that since there is no absolute coplanar two object planes in reality, in the actual tip, for the two coplanar planes mentioned in the utility model, a certain height can be allowed The error, specifically, the height error is not more than 0.1mm. The mirror surface 210 of the camera 200 is coplanar with the first plane 101, so that the mirror surface 210 of the camera 200 will not be too high, preventing the camera 200 from falling off the protection of the casing 100, and being directly exposed to the external environment, which is easy to be damaged by collision; The mirror surface 210 will not be too low, so as to prevent the housing 100 from blocking the field of view of the camera 200, which is not conducive to surgical work.

In the second installation step, the instrument tube 300 is installed in the second installation hole 120 , and the end surface of one end of the instrument tube 300 is lower than the second plane 102 . The instrument tube 300 is a working channel provided on the tip for the passage of instruments. There are various surgical instruments, such as surgical forceps, suction tubes, etc., and the instrument tube 300 can pass through one or more surgical instruments at the same time. The instrument tube 300 is provided to facilitate the passage of surgical instruments, and at the same time facilitate the connection and communication with the instrument tube 300 of the endoscope insertion part. It should be understood that in the prior art, the instrument tube 300 is generally set to be flat with the end surface of the tip housing 100, but since the instrument tube 300 is often made of stainless steel, setting it to be level with the end surface will cause scratches on the human body during installation or use. Therefore, in order to prevent scratches on the human body, the flat/protruding part of the instrument tube 300 will be ground, which is time-consuming and labor-intensive and difficult to operate; and the tip of the utility model is installed on one end of the instrument tube 300 The end surface is naturally lower than the end surface (second plane 102 ) of the tip housing 100 , so the improved tip is safe and beautiful, and does not require time-consuming and labor-intensive grinding of the instrument tube 300 .

Firstly, due to the existence of the height difference, the tip head made by the utility model is difficult for the lower plane to come into contact with the body fluid (the higher plane will first contact the inner cavity wall of the human body, thereby preventing the lower plane from contacting the body fluid) The lower plane is less likely to be contaminated by the body fluid on the inner cavity wall of the human body), that is, the contact area between the end of the tip and the body fluid is reduced, so that the influence of the body fluid on the tip is smaller, specifically For example, it can make less body fluid adhered to the tip, reduce the increase in the weight of the tip during the operation, and reduce the impact on the doctor's hand feeling when operating the endoscope; secondly, due to the protective effect of the higher first plane 101 , the instrument tube 300 located on the lower second plane 102 is not easy to enter body fluids, and the viscous adhesion of body fluids will have a greater adverse effect on the instruments in the instrument tube 300, and it is not easy to Moving and operating the instrument also affects the feel of the operating instrument, especially when suddenly getting rid of the adhesion, it is easy to cause a sudden increase in the force of the operating instrument, thereby increasing the risk of surgery; again, the position of the mirror 210 is relatively high, which means There is no additional position blocking the field of view of the camera 200 on the end surface of the tip, and the information that the mirror 210 can receive is wider, so that the surgical field of view of the camera 200 is wider and better; then, because the body fluid on the tip can adhere The area of the body becomes smaller, that is, there is less adhered body fluid on the tip, and the adhered body fluid is closer to the suspended edge area of the first plane 101. Specifically, the body fluid on the mirror surface 210 of the camera 200 is closer to the suspended edge area. Closer (that is, closer to the area below the first plane 101, more specifically, the second plane 102 here), so when the body fluid is shaken off or dropped, the body fluid on the mirror surface 210 of the camera 200 is close to the second plane 102. In the direction of the plane 102 (or in other words, from the mirror 210 to the direction of the second plane 102), it only needs to move a small distance to break away from the contact with the first plane and be shaken off, thrown off (or slipped to the second plane 102). 102 on the plane, no longer affect the camera 200 on the first plane 101), and the original apex, the body fluid on the mirror 210 of the camera 200 needs to move a farther distance before it can move to the edge of the end face Therefore, with less force, the body fluid adhering to the tip can be shaken off and thrown off more conveniently, and the cleaning efficiency of the body fluid is also higher and faster, so that it is convenient to remove the tip Keep it in a relatively clean state, which is convenient for doctors to operate the endoscope. It not only prevents body fluids from blocking the camera 200, ensures a clear view of the endoscope, but also prevents body fluids from entering the instrument tube 300 and affecting the manipulation of the instrument; finally, the height of the mirror surface 210 higher, and the height of the second plane 102 is lower, so in practice, the body fluid is easier to slide down from the high mirror surface 210 to the second plane 102, and it is not easy to slide from the second plane 102 to the mirror surface 210, so It can effectively reduce the continuous impact of body fluids on the lens and ensure the image quality of the camera 200. It should be particularly understood that, even when both the first plane 101 and the second plane 102 are contaminated with body fluid, referring to the above content, because of the existence of the height difference between the first plane 101 and the second plane 102, the body fluid on the first plane 101 is also more It is easy to be shaken off, thrown off, or slipped onto the second plane 102, so that it no longer affects the camera 200 on the first plane 101; and, since body fluids also have an adhesive attraction to each other, on the one hand, because The existence of the height difference divides the end surface of the tip into two parts, so the plane where the camera 200 mirror 210 is located becomes smaller, the body fluid on this plane also becomes smaller, and the adhesion attraction of body fluids to each other is reduced, making it easier to throw off On the other hand, the body fluid on the third inclined plane 103 or the second plane 102 also has an adhesive attraction to the body fluid on the first plane 101 that is in contact with them, and when the body fluid is shaken off or dropped , due to the existence of the adhesive force, the body fluid is more likely to slide down to the third slope 103 or the second plane 102, on the contrary, due to the existence of the height difference, the body fluid on the third slope 103 and the second plane 102 is not easily Adhesive attraction pulls into the first plane 101 , so the existence of the height difference further facilitates the doctor to shake off the bodily fluid on the first plane 101 .

Referring to Fig. 2 and Fig. 4, in some embodiments of the present utility model, also comprise the 3rd installation step; In the step of manufacturing shell 100, the end face of one end of shell 100 is also provided with the 3rd slope 103, one end of the 3rd slope 103 Connected to the first plane 101, the other end of the third inclined plane 103 is connected to the second plane 102, the third inclined plane 103 is provided with a third installation hole 130; in the third installation step, the illuminating lamp 400 is arranged in the third installation hole 130 , the lamp surface 410 of the illuminating lamp 400 is in the same plane as the third slope 103 .

Since one end of the third slope 103 is connected with the first plane 101, and the other end of the third slope 103 is connected with the second plane 102, the third slope 103 is a transition plane between the first plane 101 and the second plane 102, connecting Therefore, most of the third slope 103 is lower than the first plane 101 and higher than the second plane 102 , and there is an inclination angle between the third slope 103 and the first plane 101 and the second plane 102 . While the lighting lamp 400 is arranged in the third installation hole 130, the lamp surface 410 of the lighting lamp 400 is coplanar with the third slope 103, so that the light emitted by the lighting lamp 400 cannot directly enter the camera 200 (even from the lamp surface). 410 emission, and the light coplanar with the lamp surface 410, because the existence of the slant angle of the third slope 103, it is also impossible to directly enter the mirror surface 210), preventing the light from the illuminating lamp 400 directly entering the camera 200 from affecting the camera 200. Imaging effect.

Referring to FIG. 2 and FIG. 5 , in some embodiments of the present invention, a fixing step is further included, using insulating glue to fix the camera 200 and the lighting lamp 400 in the installation hole.

By filling the gap between the camera 200, the lighting lamp 400, and the housing 100 with glue, the camera 200 can be fixed in the first installation hole 110, and the lighting lamp 400 can be fixed in the third installation hole 130, and after the glue fills the gap , Also prevent external objects (such as body fluids, disinfectant water, etc.) from entering the interior of the housing 100 through the gaps, polluting and corroding the components on the tip, and even causing cross-infection of patients.

Referring to Fig. 1 and Fig. 2, in some embodiments of the present invention, a wrapping step is also included, the cooling fin 500 is fixed on the outside of the housing 100, one side of the cooling fin 500 abuts against the camera 200, and the other side of the cooling fin 500 The side abuts the instrument tube 300, and the outer surface of the heat sink 500 is a part of the cylindrical surface. The gap between the shell 100, the heat sink 500, the camera 200, the instrument tube 300 (and the lighting lamp 400) is filled with glue, and the skin is used to wrap it. The outer surface of the heat sink 500 and the housing 100 forms a cylindrical tip.

The heat sink 500 is made of a material with good thermal conductivity, such as a metal material, specifically, a copper sheet. After the tip end is installed on the insertion part of the endoscope, the cooling fin 500 can abut against the snake bone or directly abut against the hard insertion tube, so that the heat emitted by the camera 200 and the illuminating lamp 400 can be transferred to the snake bone, hard tube, etc. At the same time, because the instrument tube 300 is also made of metal material, and its contact area is relatively large, and the ventilation is relatively good, so when the heat sink 500 touches the instrument tube 300, the instrument tube 300 can also play the role of auxiliary heat dissipation. Cylinder, including the upper and lower bottom surfaces and the curved surface of the side; the outer surface of the heat sink 500 is a part of the cylindrical surface, which can play a role in supporting and shaping the subsequent wrapping of the outer skin, so that the tip after the final molding is still roughly a cylindrical shape , reduce the uneven and unsightly surface of the tip, and increase the appearance of the product. Therefore, the heat sink 500 is provided to improve the hot problem of the tip. The function of glue filling can refer to the above-mentioned relevant content, and will not be repeated here. It should be understood that the inside and outside in the present invention refer to the side pointing toward (or close to) the reference axis as inside, and the side away from (or away from) the reference axis as outside.

Referring to FIG. 1 and FIG. 3 , the tip head according to the embodiment of the present invention is manufactured by the above-mentioned manufacturing method of the tip head, and includes a housing 100 , a camera head 200 and an instrument tube 300 .

The housing 100 has a first plane 101 and a second plane 102 on one end face of the housing 100, the first plane 101 and the second plane 102 have a height difference, the first plane 101 is higher than the second plane 102, and the first plane 101 is set There is a first installation hole 110 , and a second installation hole 120 is provided on the second plane 102 . The housing 100 is injection molded from plastic.

The camera 200 is installed in the first installation hole 110 , and the mirror surface 210 of the camera 200 is coplanar with the first plane 101 .

The instrument tube 300 is installed in the second installation hole 120 , and the end surface of one end of the instrument tube 300 is lower than the second plane 102 .

It should be understood that, on the basis that the mirror surface 210 of the camera 200 and the first plane 101 are both higher than the second plane 102, the height difference between the mirror surface 210 of the camera 200 and the first plane 101 can be set to be no more than 0.1 mm. Specifically, the mirror surface 210 of the camera 200 can be selected to be lower than the first plane 101 , or the mirror surface 210 of the camera 200 can be selected to be higher than the first plane 101 , or the mirror surface 210 of the camera 200 can be selected to be coplanar with the first plane 101 . Although the mirror surface 210 of the camera 200 being higher or lower than the first plane 101 has a certain impact on the beneficial effects described above, in these cases, there are still certain beneficial effects mentioned above.

Referring to Fig. 3 and Fig. 6, in some embodiments of the present invention, the height difference H is 0.2mm-0.5mm.

The height difference between the first plane 101 and the second plane 102 cannot be too large, otherwise it will affect the operation of the instrument; the height difference can not be too small, too small can not play a good beneficial effect, so the height difference can be set to 0.2mm-0.5 mm.

Referring to Fig. 1 and Fig. 4, in some embodiments of the present utility model, one end face of the housing 100 is also provided with a third slope 103, one end of the third slope 103 is connected with the first plane 101, and the other end of the third slope 103 Connected with the second plane 102 , the third slope 103 extends from one end of the third slope 103 to the other end of the third slope 103 , and the second installation hole 120 is not located on the extension surface (or extension path) of the third slope 103 .

Referring to the above related content, the setting of the third slope 103 facilitates the flow of body fluid on the first plane 101 to the second plane 102, thereby reducing the blocking of the camera 200 by body fluid; and the second installation hole 120 is not located on the third plane 102 On the extension path of the inclined plane 103, the body fluid that slides down on the second plane 102 is not easy to directly enter into the instrument tube 300 and affect the manipulation of the instrument, but it is easier to slide down to the edge of the second plane 102, so that it is easy to leak from the tip end surface. It slides off completely, and the adverse effect on the tip becomes smaller. Specifically, in this embodiment, two third slopes 103 are provided, and the two third slopes 103 are roughly distributed in a figure-eight shape, and the second installation hole 120 is just located in the lower area of the center of the figure-eight shape, so from the third The bodily fluid sliding down the slope 103 is not easy to enter into the second installation hole 120 (the instrument tube 300 ).

Referring to Fig. 1 and Fig. 4, in some embodiments of the present invention, a lighting lamp 400 is also included, and one end surface of the housing 100 is also provided with a third slope 103, and one end of the third slope 103 is connected with the first plane 101, and the second The other end of the three slopes 103 is connected to the second plane 102, the third slope 103 is provided with a third installation hole 130, the lighting lamp 400 is installed in the third installation hole 130, the lamp surface 410 of the lighting lamp 400 and the third slope 103 share noodle.

The lamp surface 410 of the illuminating lamp 400 is the end face of the end of the illuminating lamp 400 facing the outside, through which the light emitted by the illuminating lamp 400 is emitted to the outside. In this embodiment, the illuminating lamp 400 is an LED lamp, and is controlled by the lamp control module. The illuminating lamp 400 plays a role of illuminating, providing light for the unrelated environment of the human body cavity, and facilitating the camera 200 to collect imaging information. It should be understood that the connection plane between the first plane 101 and the second plane 102 may also be vertical (or perpendicular to the two planes), and the illuminating lamp 400 is directly arranged on the first plane 101 .

1, 3 and 6, in some embodiments of the present invention, the inclination angle of the third slope 103 relative to the first plane 101 is 10°-20° (or 160°-170°).
