Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to the endoscope tube structure and endoscope. Background Technology

[0002] An endoscope tube generally consists of an outer tube, and an optical channel tube, an instrument channel tube, and an irrigation channel tube located inside the outer tube. During surgery, surgical instruments are inserted into the body through the instrument channel tube to remove or treat diseased tissue; the optical channel tube contains lenses, which can be used to observe the treatment process in real time through imaging; the irrigation channel tube is used to introduce liquids such as drugs and detergents to irrigate and rinse the patient.

[0003] In existing technologies, during surgery, instruments such as forceps and drills may pass through the instrument channel tube of the endoscope. If the drill is not operated properly or when grasping large bone tissue, the instrument channel tube may be deformed. The deformation of the instrument channel tube will squeeze the optical channel tube, causing the optical channel tube to fail to seal or the lens to break, resulting in damage to the endoscope.

[0044] See Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of an endoscope tube structure provided in one embodiment of the present invention, with the outer tube removed. Figure 2 This is a cross-sectional view of an endoscope tube structure provided in an embodiment of the present invention. Figure 3 This is a cross-sectional view of an endoscope tube structure provided in another embodiment of the present invention. An embodiment of the present invention provides an endoscope tube structure 10, including an outer tube 100, an optical channel tube 200, an instrument channel tube 30, and a support member 50; the optical channel tube 200, the instrument channel tube 30, and the support member 50 are all disposed within the outer tube 100, with the optical channel tube 200 and the instrument channel tube 30 arranged adjacent to each other; the support member 50 includes a first support portion 510, which is supported between the outer wall of the optical channel tube 200 and the outer wall of the instrument channel tube 300.

[0045] Specifically, in this application, the first support portion 510 is positioned between the outer walls of the optical channel tube 200 and the instrument channel tube 300, thereby increasing the rigidity and strength of both. This prevents deformation of the instrument channel tube 300 during surgery, even under significant external forces, thus reducing the pressure exerted on the optical channel tube 200 by deformation of the instrument channel tube 300. This lowers the risk of seal failure or lens breakage in the optical channel tube 200, ultimately improving the stability and reliability of the endoscope tube structure 10. Furthermore, the first support portion 510 is connected to both the outer walls of the optical channel tube 200 and the instrument channel tube 300, preventing movement of the first support portion 510 and enhancing support reliability.

[0046] It should be noted that the adjacent arrangement in this embodiment can be understood as two things being next to each other, or as two things being close to each other or having a gap between them.

[0047] See Figure 2 , Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of a support block in an endoscope tube structure according to an embodiment of the present invention. In one embodiment, a first support portion 510 is sandwiched between the optical channel tube 200 and the instrument channel tube 300. The first support portion 510 includes a first support surface 511, which is attached to the outer wall of the optical channel tube 200, thereby further increasing the rigidity and strength of the optical channel tube 200, reducing the failure of the optical channel tube 200 during the deformation process of the instrument channel tube 300, and improving the stability and reliability of the endoscope tube structure 10.

[0048] See Figure 2 , Figure 3 and Figure 4 In one embodiment, a first support portion is sandwiched between the optical channel tube and the instrument channel tube. The first support portion 510 includes a second support surface 512, which is attached to the outer wall of the instrument channel tube 300, thereby further increasing the rigidity and strength of the instrument channel tube 300, making the instrument channel tube 300 less prone to deformation or damage, thereby reducing the compression on the optical channel tube 200 and improving the stability and reliability of the endoscope tube structure 10.

[0049] See Figure 1 , Figure 2 and Figure 3In a preferred embodiment, the endoscope tube structure further includes a flushing channel tube 400, which is inserted into the outer tube 100. The optical channel tube 200, the instrument channel tube 300, and the flushing channel tube 400 are arranged adjacent to each other. The first support part 510 is also supported on the outer wall of the flushing channel tube 400.

[0050] Specifically, the first support portion 510 is supported between the outer walls of the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400, thereby connecting the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400 into a whole. By arranging the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400 adjacent to each other in pairs, the first support portion 510 can be limited from three directions, ensuring stable support for the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400. This improves the stability of the second support portion 520, thereby further increasing the rigidity and strength of the optical channel tube 200 and the instrument channel tube 300. The first support portion 510 is connected to the outer wall of the filling channel tube 400.

[0051] See Figure 2 , Figure 3 and Figure 4 In one embodiment, the first support portion 510 includes a third support surface 513, which is attached to the outer wall of the irrigation channel tube 400 to achieve stable positioning of the first support portion 510, improve the stability of the first support portion 510, and further stabilize and improve the rigidity and strength of the optical channel tube 200 and the instrument channel tube 300.

[0052] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the optical channel tube 200, the irrigation channel tube 400, the instrument channel tube 300 and the first support portion 510 all extend along the axial direction of the outer tube 100; the first support portion 510 is sandwiched between the optical channel tube 200, the irrigation channel tube 400 and the instrument channel tube 300.

[0053] Furthermore, the first support portion 510 also includes a first support surface 511, a second support surface 512, and a third support surface 513, wherein: the first support surface 511 is disposed on the side surface of the first support portion 510 facing the optical channel tube 200, and the first support surface 511 matches the outer wall shape of the optical channel tube 200; the second support surface 512 is disposed on the side surface of the first support portion 510 facing the instrument channel tube 300, and the second support surface 512 matches the outer wall shape of the instrument channel tube 300; the third support surface 513 is disposed on the side surface of the first support portion 510 facing the irrigation channel tube 400, and the third support surface 513 matches the outer wall shape of the irrigation channel tube 400.

[0054] Specifically, the first support surface 511 matches the outer wall shape of the optical channel tube 200, the second support surface 512 matches the outer wall shape of the instrument channel tube 300, and the third support surface 513 matches the outer wall shape of the filling channel tube 400, thereby filling the gap between the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400 with the first support part 510, thereby improving the overall strength between the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400, and enabling the optical channel tube 200, the instrument channel tube 300, and the filling channel tube 400 to be precisely positioned.

[0055] The first support 510 can be bonded to the optical channel tube 200, the instrument channel tube 300 and / or the irrigation channel tube 400, or other connection methods such as welding.

[0056] Furthermore, the length of the first support part 510 does not extend through the entire outer tube 100. When used alone, the first support part 510 can be used to locally strengthen the stress-bearing part at the front end of the endoscope tube structure 10. It can also be set at different positions in the axial direction of the outer tube 100 as needed to simultaneously strengthen different positions of the endoscope tube structure 10. This reduces the processing difficulty of the first support part 510 and does not cause a significant increase in product weight.

[0057] In one embodiment, the optical channel tube 200, the instrument channel tube 300, and the irrigation channel tube 400 abut against each other in pairs, thereby confining the first support portion 510 within a triangular-like area, thereby further improving the stability of the first support portion 510 and increasing the overall strength between the optical channel tube 200, the instrument channel tube 300, and the irrigation channel tube 400.

[0058] In other embodiments, there may also be a gap between the outer walls of the optical channel tube 200 and the instrument channel tube 300, and there may also be a gap between the irrigation channel tube 400 and the optical channel tube 200.

[0059] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the support block 500 further includes a second support portion 520, which is supported between the outer wall of the optical channel tube 200 and the inner wall of the outer tube 100. This improves the rigidity and strength of the optical channel tube 200 and the outer tube 100, reduces the deformation of the outer tube 100 under stress, and reduces the compression of the optical channel tube 200 by the deformation of the outer tube 100. This reduces the risk of sealing failure of the optical channel tube 200 or breakage of the inner lens of the optical channel tube 200, and improves the stability and reliability of the endoscope tube structure 10. The second support portion 520 is connected to both the outer wall of the optical channel tube 200 and the outer wall of the outer tube 100, thereby preventing the second support portion 520 from shifting and improving support reliability.

[0060] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the second support portion 520 is sandwiched between the outer wall of the optical channel tube 200 and the inner wall of the outer tube 100. The second support portion 520 includes a fourth support surface 521, which is attached to the outer wall of the optical channel tube 200, thereby further increasing the rigidity and strength of the optical channel tube 200, reducing the failure of the optical channel tube 200 during the deformation process of the outer tube 100, and improving the stability and reliability of the endoscope tube structure 10.

[0061] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the second support portion 520 is sandwiched between the outer wall of the optical channel tube 200 and the inner wall of the outer tube 100. The second support portion 520 includes a fifth support surface 522, which is in close contact with the inner wall of the outer tube 100, thereby further increasing the rigidity and strength of the outer tube 100, making the outer tube 100 less prone to deformation or damage, thereby reducing the squeezing of the optical channel tube 200 by the outer tube 100 during the stress process, and improving the stability and reliability of the endoscope tube structure 10.

[0062] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the endoscope tube structure further includes the aforementioned irrigation channel tube 400; the second support portion 520 is also sandwiched between the outer wall of the optical channel tube 200, the outer wall of the irrigation channel tube 400, and the inner wall of the outer tube 100.

[0063] Specifically, the second support portion 520 is positioned between the optical channel tube 200, the outer tube 100, and the filling channel tube 400, thereby connecting the optical channel tube 200, the outer tube 100, and the filling channel tube 400 into a single unit. By arranging the optical channel tube 200, the outer tube 100, and the filling channel tube 400 adjacent to each other in pairs, the second support portion 520 can be limited from three directions, ensuring stable support for the optical channel tube 200, the outer tube 100, and the filling channel tube 400, thus improving the stability of the second support portion 520 and further increasing the rigidity and strength of the optical channel tube 200 and the outer tube 100. The second support portion 520 is connected to the outer wall of the filling channel tube 400.

[0064] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the second support portion 520 includes a sixth support surface 523, which is attached to the outer wall of the injection channel tube 400 to achieve stable positioning of the second support portion 520 and improve the stability of the second support portion 520, thereby further stabilizing and improving the rigidity and strength of the optical channel tube 200 and the outer tube 100.

[0065] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the optical channel tube 200, the irrigation channel tube 400, the instrument channel tube 300, and the second support portion 520 all extend along the axial direction of the outer tube 100.

[0066] Furthermore, the second support portion 520 also includes a fourth support surface 521, a fifth support surface 522, and a sixth support surface 523, wherein: the fourth support surface 521 is disposed on the side surface of the second support portion 520 facing the optical channel tube 200, and the fourth support surface 521 matches the shape of the outer wall of the optical channel tube 200; the fifth support surface 522 is disposed on the side surface of the second support portion 520 facing the inner wall of the outer tube 100, and the fifth support surface 522 matches the shape of the inner wall of the outer tube 100; the sixth support surface 523 is disposed on the side surface of the second support portion 520 facing the filling channel tube 400, and the sixth support surface 523 matches the shape of the outer wall of the filling channel tube 400.

[0067] Specifically, the fourth support surface 521 matches the outer wall shape of the optical channel tube 200, the fifth support surface 522 matches the inner wall shape of the outer tube 100, and the sixth support surface 523 matches the outer wall shape of the filling channel tube 400, thereby filling the gap between the optical channel tube 200, the outer tube 100, and the filling channel tube 400 with the second support part 520, thereby improving the overall strength between the optical channel tube 200, the outer tube 100, and the filling channel tube 400, and enabling precise positioning of the optical channel tube 200, the outer tube 100, and the filling channel tube 400.

[0068] The second support 520 can be bonded to the optical channel tube 200, the outer tube 100 and / or the filling channel tube 400, or other connection methods such as welding.

[0069] Furthermore, the second support portion 520 does not extend through the entire outer tube 100. When used alone, it can be used for local reinforcement of the stress-bearing portion at the front end of the endoscope tube structure 10. It can also be positioned at different locations along the axial direction of the outer tube 100 as needed to simultaneously reinforce different locations of the endoscope tube structure 10. This reduces the processing difficulty of the second support portion 520 and does not significantly increase the product weight. Preferably, the axial length of the second support portion 520 is the same as the axial length of the first support portion 510.

[0070] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the optical channel tube 200, the outer tube 100 and the filling channel tube 400 abut against each other, that is, the second support 520 is confined within a triangular area, thereby further improving the support stability of the second support 520 and increasing the overall strength between the optical channel tube 200, the outer tube 100 and the filling channel tube 400.

[0071] In other embodiments, there may be a gap between the optical channel tube 200 and the inner wall of the outer tube 100, and there may also be a gap between the filling channel tube 400 and the optical channel tube 200.

[0072] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment, the first support portion 510 is connected to the second support portion 520.

[0073] Specifically, there is a gap between the flushing channel tube 400 and the optical channel tube 200. The first support part 510 and the second support part 520 are connected through the gap between the flushing channel tube 400 and the optical channel tube 200, thereby connecting the outer tube 100, the optical channel tube 200, the flushing channel tube 400, the instrument channel tube 300 and the support block 500 into a whole. This further increases the rigidity and strength of the outer tube 100, the optical channel tube 200 and the instrument channel tube 300, thereby reducing the deformation of the outer tube 100 and the instrument channel tube 300 under external force, and reducing the failure of the optical channel tube 200 during the deformation and compression process of the outer tube 100 and the instrument channel tube 300, thus improving the stability and reliability of the endoscope tube structure 10.

[0074] Furthermore, the first support surface 511 is connected to the fourth support surface 521, and the first support surface 511 and the fourth support surface 521 are located on the same curved surface. The third support surface 513 is connected to the sixth support surface 523, and the third support surface 513 and the sixth support surface 523 are located on the same curved surface, thereby facilitating the processing of the support block 500.

[0075] In other embodiments, the first support portion 510 and the second support portion 520 may also be provided separately, so that the support block 500 can be split according to the actual situation.

[0076] See Figure 1 , Figure 3 and Figure 5 , Figure 5 This is a schematic diagram of a support member in an endoscope tube structure according to another embodiment of the present invention. The support member 50 includes two interconnected support blocks 500, with a mounting hole 530 between the two support blocks 500 for the optical channel tube 200 to pass through. This facilitates the limiting of the optical channel tube 200 and allows the support member 50 to cover the optical channel tube 200 within the mounting hole 530, thereby improving the circumferential stiffness and strength of the optical channel tube 200, preventing deformation of the optical channel tube 200 under the pressure of the outer tube 100 and the instrument channel tube 300, and improving the stability and reliability of the endoscope tube structure 10.

[0077] See Figure 1 , Figure 3 and Figure 5 In one embodiment, there are two flushing channel tubes 400, which are disposed on both sides of the optical channel tube 200, and a support block 500 is provided between the two flushing channel tubes 400 and the optical channel tube 200.

[0078] Specifically, the two first support parts 510 are connected to each other on the side near the optical channel tube 200, and the two second support parts 520 are connected to each other on the side near the optical channel tube 200, so that the outer tube 100, the optical channel tube 200, the instrument channel tube 300, the support member 50 and the two irrigation channel tubes 400 are connected into a whole, further increasing the rigidity and strength of the outer tube 100, the optical channel tube 200 and the instrument channel tube 300.

[0079] The optical channel tube 200 has gaps between itself, the filling channel tube 400, and the outer tube 100. The two first support parts 510 are connected through the gaps between the optical channel tube 200 and the filling channel tube 400, and the two second support parts 520 are connected through the gaps between the optical channel tube 200 and the outer tube 100.

[0080] Furthermore, the two first support surfaces 511 are connected and located on the same curved surface, and the two fourth support surfaces 521 are connected and located on the same curved surface, thereby forming the wall of the mounting hole 530 through the first support surfaces 511 and the fourth support surfaces 521 on the two support blocks 500, which improves the processing convenience of the support member 50.

[0081] Furthermore, the two second support surfaces 512 on the two support blocks 500 are connected and located on the same curved surface, and the curved surface is externally tangent to the wall of the mounting hole 530, thereby improving the utilization rate of the internal space of the outer tube 100.

[0082] Among them, the two fifth support surfaces 522 on the two support blocks 500 are connected and located on the same curved surface, and the curved surface is internally tangent to the hole wall of the mounting hole 530, thereby improving the utilization rate of the internal space of the outer tube 100.

[0083] In addition, the ends of the support member 50 are rounded to prevent the support member 50 from warping and to improve the stability and reliability of the support member 50.

[0084] In other embodiments, the two support blocks 500 can also be set separately, so that the support 50 can be disassembled according to the actual situation.

[0085] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the side of the instrument channel tube 300 away from the optical channel tube 200 abuts against the inner wall of the outer tube 100, thereby improving the utilization rate of the space inside the outer tube 100.

[0086] Furthermore, the empty space formed by the outer tube 100, the optical channel tube 200, the flushing channel tube 400, the instrument channel tube 300, and the support 50 is fitted with an illumination fiber optic cable 600, which can illuminate the object being observed when in use.

[0087] See Figures 1-6 , Figure 6 This is a schematic diagram of an endoscope provided according to an embodiment of the present invention. The embodiment of the present invention also includes an endoscope comprising the aforementioned endoscope tube structure 10. In this application, a first support portion 510 is provided between the outer wall of the optical channel tube 200 and the outer wall of the instrument channel tube 300 to improve the rigidity and strength of the optical channel tube 200 and the instrument channel tube 300. This reduces the deformation of the instrument channel tube 300 and the compression of the optical channel tube 200 by the deformation of the instrument channel tube 300, thereby reducing the risk of sealing failure of the optical channel tube 200 or breakage of the inner lens of the optical channel tube 200, and improving the stability and reliability of the endoscope tube structure 10.
