[0030] Referring to FIG. 8 , an endoscope 10 provided in one embodiment of the present application includes a camera assembly 200, a catheter assembly 300 and a tip 100, and the camera assembly 200 and the catheter assembly 300 are both connected to the tip 100. The camera assembly 200 and the catheter assembly 300 can be arranged at the same end of the tip 100, the camera assembly 200 can include a camera element and a lighting element, the catheter assembly 300 can include a plurality of catheters, and the catheter assembly 300 is used to pass surgical instruments or to provide liquid circulation. The tip 100 includes a first mounting member 110 and a second mounting member 120, the first mounting member 110 and the second mounting member 120 are connected to each other, the first mounting member 110 is used to install the camera assembly 200, and the second mounting member 120 is used to install the catheter assembly 300.
[0031] In some embodiments, both the first mounting member 110 and the second mounting member 120 may be made of metal materials, and both may be made of the same metal material, for example, both the first mounting member 110 and the second mounting member 120 may be made of stainless steel materials, specifically stainless steel 316L. The first mounting member 110 and the second mounting member 120 may be separately processed and formed, and then fixedly connected by welding, so that the first mounting member 110 and the second mounting member 120 are combined to form an integral tip 100. The first mounting member 110 and the second mounting member 120 may be welded and connected by laser welding.
[0032] In some embodiments, the first mounting member 110 is provided with a first accommodating cavity 111 and a first mounting hole 112, the first accommodating cavity 111 and the first mounting hole 112 are interconnected, and the first mounting hole 112 is used to install the camera assembly 200. Specifically, the camera assembly 200 is inserted into the first mounting hole 112 and matched with the first mounting hole 112, thereby achieving the preliminary positioning and preliminary connection of the camera assembly 200 and the first mounting member 110. The first accommodating cavity 111 is used to pass glue, and the glue can enter the gap in the first mounting hole 112 that is not filled by the camera assembly 200. After the glue is cured, a glue body is formed to connect the camera assembly 200 and the first mounting member 110 together. Of course, after the glue in the first accommodating cavity 111 is cured, a filling body that fills the first accommodating cavity 111 will be formed, and both the glue body and the filling body can play a good sealing role for the first mounting hole 112 and the first accommodating cavity 111. Obviously, after the glue is cured, the camera assembly 200 and the first mounting member 110 can be completely connected.
[0033] In some embodiments, the second mounting member 120 is provided with a second accommodating cavity 121 and a second mounting hole 122, the second accommodating cavity 121 and the second mounting hole 122 are connected to each other, and the second mounting hole 122 is used to install the catheter assembly 300. Specifically, the catheter assembly 300 is inserted into the second mounting hole 122 and matched with the second mounting hole 122, thereby achieving the preliminary positioning and preliminary connection of the catheter assembly 300 and the second mounting member 120. The second accommodating cavity 121 is used to pass glue, and the glue can enter the gap in the second mounting hole 122 that is not filled by the catheter assembly 300. After the glue is cured, a glue body is formed to connect the catheter assembly 300 and the second mounting member 120 together. Of course, after the glue in the second accommodating cavity 121 is cured, a filling body that fills the second accommodating cavity 121 will be formed, and both the glue body and the filling body can play a good sealing role for the second mounting hole 122 and the second accommodating cavity 121. Obviously, after the glue is cured, the complete connection between the imaging catheter assembly 300 and the second mounting member 120 can be achieved.
[0034] In some embodiments, the second mounting member 120 has a bearing surface 123 and a limiting surface 124, the bearing surface 123 and the limiting surface 124 are connected at an angle, and the bearing surface 123 and the limiting surface 124 can be perpendicular to each other. The first mounting member 110 is carried on the bearing surface 123, so that the first mounting member 110 is welded to the bearing surface 123, thereby realizing the welding connection relationship between the first mounting member 110 and the second mounting member 120. One of the second mounting member 120 and the first mounting member 110 has a protrusion 114 and the other has a clamping hole 1241, the clamping hole 1241 cooperates with the protrusion 114, and the protrusion 114 or the clamping hole 1241 of the second mounting member 120 is set on the limiting surface 124. Before welding the first mounting member 110 and the second mounting member 120, firstly, the clamping hole 1241 is matched with the protrusion 114, so that the second mounting member 120 can position the first mounting member 110 in a direction parallel to the bearing surface 123; then, the first mounting member 110 is supported on the bearing surface 123, so that the second mounting member 120 can position the first mounting member 110 in a direction perpendicular to the bearing surface 123; finally, the first mounting member 110 and the second mounting member 120 are welded, so as to improve the welding accuracy between the first mounting member 110 and the second mounting member 120.
[0035] In some embodiments, the protrusion 114 can be arranged on the first mounting member 110, and the locking hole 1241 is arranged on the limiting surface 124. Specifically, the first mounting member 110 may include a mounting body 113 and a protrusion 114, the first mounting hole 112 and the first accommodating cavity 111 are both arranged on the mounting body 113, and the protrusion 114 is arranged to protrude relative to the mounting body 113. The locking hole 1241 is formed by recessing a portion of the limiting surface 124 to a set depth. The number of the locking holes 1241 and the protrusion 114 is equal and forms a one-to-one correspondence, so that different protrusions 114 cooperate with different locking holes 1241 respectively. For example, the number of the locking holes 1241 and the protrusion 114 can be two respectively.
[0036] For the assembly of the endoscope 10, first, the camera assembly 200 can be installed on the first mounting member 110, and the catheter assembly 300 can be installed on the second mounting member 120, and then the protrusion 114 on the first mounting member 110 can be matched with the card hole 1241 on the limiting surface 124, and then the first mounting member 110 is supported on the supporting surface 123, and finally the first mounting member 110 and the second mounting member 120 are welded and connected, thereby realizing the assembly of the endoscope 10.
[0037] If the tip 100 is manufactured in an integrated molding mode, on the one hand, the structure of the tip 100 is relatively complex, which will increase the difficulty and time of processing the tip 100, thereby increasing the processing cost of the tip 100 and the endoscope 10, and ultimately increasing the manufacturing cost of the tip 100 and the endoscope 10. On the other hand, during the assembly process of the camera assembly 200 and the catheter assembly 300 relative to the tip 100, given the small size of the tip, the components installed first will interfere with the components installed later, thereby affecting the assembly efficiency of the camera assembly 200 and the catheter assembly 300, thereby increasing the assembly cost of the endoscope 10, and ultimately increasing the manufacturing cost of the endoscope 10. On the other hand, after the installation of one of the camera assembly 200 and the catheter assembly 300 is completed, it needs to be tested to determine whether it is qualified. If the assembly of the assembly and the tip is unqualified, the entire tip and the assembly will be scrapped, thereby increasing the material cost in the scrapping process, and further increasing the manufacturing cost of the endoscope 10. It can be understood that since the first installed assembly will interfere with the later installed assembly, it will also affect the assembly yield, thereby increasing the scrap rate and pushing up the manufacturing cost of the endoscope 10.
[0038] The tip and the endoscope 10 in the above embodiment may have the following advantages:
[0039] First, considering that the first mounting member 110 and the second mounting member 120 are manufactured separately and assembled to form the tip by welding, the processing efficiency of the first mounting member 110 and the second mounting member 120 will be improved, thereby reducing the processing cost of the entire tip, and ultimately reducing the manufacturing cost of the tip and the endoscope 10.
[0040] Second, since the first mounting member 110 and the second mounting member 120 are manufactured separately, the interference between the catheter assembly 300 and the second mounting member 120 can be completely eliminated during the assembly of the camera assembly 200 and the first mounting member 110, thereby improving the assembly efficiency of the camera assembly 200 and the first mounting member 110. Similarly, the interference between the camera assembly 200 and the first mounting member 110 can be completely eliminated during the assembly of the catheter assembly 300 and the second mounting member 120, thereby improving the assembly efficiency of the camera catheter assembly 300 and the second mounting member 120, and ultimately improving the assembly efficiency of the endoscope 10, and reducing the assembly cost and manufacturing cost of the endoscope 10.
[0041] Third, considering that the first mounting member 110 and the second mounting member 120 are manufactured separately, when it is detected that there is an assembly problem between the camera component 200 and the first mounting member 110 resulting in failure, while the assembly between the catheter component 300 and the second mounting member 120 is qualified, the camera component 200 and the first mounting member 110 can be scrapped as a whole, while the catheter component 300 and the second mounting member 120 can be retained so that the second mounting member 120 can be welded to the next first mounting member 110 that is assembled qualifiedly, without the need to discard the entire endoscope 10, thereby reducing the material cost during the scrapping process and further reducing the manufacturing cost of the endoscope 10. Similarly, when it is detected that there is an assembly problem between the catheter assembly 300 and the second mounting member 120 and the assembly is unqualified, and the assembly between the camera assembly 200 and the first mounting member 110 is qualified, the catheter assembly 300 and the second mounting member 120 can be scrapped as a whole, and the camera assembly 200 and the first mounting member 110 can be retained, and the material cost in the scrapping process can also be reduced to reduce the manufacturing cost of the endoscope 10. It can be understood that, since the interference of the catheter assembly 300 and the second mounting member 120 on the assembly of the camera assembly 200 and the first mounting member 110 can be eliminated, the interference of the camera assembly 200 and the first mounting member 110 on the assembly of the catheter assembly 300 and the second mounting member 120 can also be eliminated, thereby improving the assembly yield of the endoscope 10, reducing the material cost in the scrapping process, and further reducing the manufacturing cost of the endoscope 10.
[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
