Description

Technical Field

[0001] This utility model relates to the technical field of fixtures, specifically to an auxiliary connecting fixture for an endoscope capillary and a curved section. Background Technology

[0002] Endoscopes, as minimally invasive medical devices for examination and treatment, are primarily used for the diagnosis and treatment of various diseases. Inserted into the body through natural openings or small surgical incisions, they allow doctors to clearly observe the internal condition, diagnose various diseases, and perform various adjunctive treatments, such as polyp removal and lithotripsy. An endoscope generally consists of an eyepiece, operating section, insertion section, bending section, and tip. The bending section is achieved through a flexible serpentine frame, which is stretched on both sides by traction wires to achieve the bending function. Capillaries wrap around the traction wires to protect them.

[0003] The existing capillary tube and the curved section have no fixed structure. The capillary tube is fixed by the last buckle at the end of the curved section. If the capillary tube cannot reach the end, the S-bend of the insertion part will warp, resulting in a loss of the bending angle. Moreover, the capillary tube is very easy to loosen and move. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide an auxiliary connecting fixture for capillary tubes and curved sections for endoscopes, which aims to solve the problems that the traditional assembly method of capillary tubes and curved sections is not reliable, is easy to loosen, and is prone to loss of bending angle.

The directional base has a directional channel formed therein, and the directional channel has a first end and a second end arranged opposite to each other. At least a portion of the directional structure is located outside the first end of the directional channel to accommodate the curved section being fixed thereon in a straight state.

[0006] The directional channel is adapted to allow a capillary to pass through it, such that one end of the capillary passes through the first end and abuts against the buckle of the curved section located on the directional structure, while the other end protrudes from the second end.

[0008] Optionally, the directional base includes a first base body and a second base body connected to each other. The first base body and the second base body are respectively provided with a first limiting groove and a second limiting groove on one side of their opposite arrangement. The first limiting groove and the second limiting groove both extend along the first direction and are open at both ends along the first direction. The openings of the first limiting groove and the second limiting groove are opposite to each other to jointly enclose and form the mounting hole.

[0009] Optionally, the orientation structure includes a welded liner rod that passes through the mounting hole, with one end protruding from the first end to accommodate a bent section, and the other end flush with the second end.

[0010] Optionally, the welding liner includes a first rod and a second rod arranged opposite to each other, the first rod being housed in the first limiting groove and adapted to the first limiting groove, and the second rod being housed in the second limiting groove and adapted to the second limiting groove.

[0011] Optionally, at least one directional channel is defined between the welding liner and the mounting hole, each directional channel extending along a first direction of the directional base, and each directional channel is adapted to allow a capillary tube to pass through it.

[0012] Optionally, the first rod body is provided with a first clearance groove on the side facing away from the opening of the first limiting groove. The first clearance groove extends along the first direction to define a directional channel between itself and the first limiting groove.

[0014] Optionally, it also includes a length measuring element for identifying the length of the capillary extending from the second end of the directional channel.

[0015] Optionally, the length measuring component includes a first scale protruding from the second end of the first base and a second scale protruding from the second end of the second base. The first scale is located on one side of the first limiting groove, and the second scale is located on one side of the second limiting groove.

[0032] This utility model provides an auxiliary connecting fixture 100 for capillary tubes and curved sections of endoscopes, combined with... Figure 1 , Figure 4 and Figure 5 As shown, the auxiliary connecting fixture 100 for the endoscope capillary and curved section is suitable for connecting the capillary 200 and the curved section 300. The capillary 200 is a flexible tube, and the curved section 300 includes a snake tube 301 and a buckle 302. The buckle 302 is engaged inside the snake tube 301, and one end of the capillary 200 can abut against the corresponding end of the buckle 302, thereby limiting the end of the capillary 200.

[0033] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, the auxiliary connecting fixture 100 for the endoscope capillary and curved section includes a directional base 1 and a directional structure 2. A directional channel is formed on the directional base 1, and the directional channel has a first end and a second end that are arranged opposite to each other. At least a portion of the directional structure 2 is located outside the first end of the directional channel to accommodate the curved section in a straight state. The directional channel is adapted to allow the capillary 200 to pass through it, such that one end of the capillary 200 passes through the first end and abuts against the buckle 302 of the curved section 300 located on the directional structure 2, while the other end protrudes from the second end.

[0034] In this embodiment, a directional channel is formed on the directional base 1. At least a portion of the directional structure 2 is located outside the first end of the directional channel, suitable for fixing the curved section in a straight state. Furthermore, the capillary 200 can pass through the directional channel, and under the guidance of the directional channel, the capillary 200 can be inserted into the curved section 300. When the capillary 200 abuts against the snap 302 within the curved section 300, it indicates that the capillary 200 is properly inserted. The portion of the capillary 200 extending into the curved section 300 is then welded and fixed to the curved section 300, ensuring that the capillary 200 is not easily loosened. The auxiliary connecting fixture 100 for the endoscope capillary and curved section simplifies the assembly operation of the capillary 200 and the curved section 300, better ensuring the size and secure fixation of the capillary 200, and guaranteeing a better bending angle, thereby improving the quality of the endoscope.

[0035] The directional base 1 has a mounting hole extending along a first direction. The directional structure 2 passes through the mounting hole, and the directional channel is formed between the directional structure 2 and the mounting hole. One end of the directional structure 2 protrudes from the mounting hole to accommodate a bent section. Preferably, the mounting hole is arranged in a straight line, so that the capillary 200 is arranged in a straight line when inserted into the mounting hole, making the insertion operation smoother and allowing for better determination of the length of the capillary 200.

[0036] The shape and size of the orientation base 1 are not specifically limited, and can be adapted according to the actual dimensions of the capillary 200 and the bent section 300. Preferably, it is combined with Figure 4 and Figure 5 As shown, the directional base 1 includes a first base 11 and a second base 12 connected to each other. The first base 11 and the second base 12 are respectively provided with a first limiting groove 111 and a second limiting groove 121 on their opposite sides. The first limiting groove 111 and the second limiting groove 121 both extend along the first direction and are open at both ends along the first direction. The openings of the first limiting groove 111 and the second limiting groove 121 are opposite to each other to form the mounting hole, which makes it easier to fix the directional structure 2 in the mounting hole and facilitates the maintenance of each base, avoiding blockage of the mounting hole.

[0037] Preferably, the first seat 11 and the second seat 12 have the same shape and size, and are both square in shape. The first direction mentioned above refers to one direction of the horizontal plane. Specifically, the first direction can refer to the left-right or front-back direction along the directional base 1, etc. Unless otherwise specified, the following description will use the left-right direction as an example. When the auxiliary connecting fixture 100 for the endoscope capillary and curved section is in normal use, the first seat 11 is positioned above the second seat 12.

[0038] The first base 11 and the second base 12 are detachably connected. Specifically, in combination... Figure 4 and Figure 5 As shown, one of the first base 11 and the second base 12 is provided with a plurality of positioning protrusions 112, and the other is provided with a plurality of positioning holes 122. The plurality of positioning protrusions 112 and the plurality of positioning holes 122 are arranged in a one-to-one correspondence and are inserted into each other. Moreover, the first base 11 and the second base 12 can also be connected and fixed by screws, bolts, etc., passing through the screw holes on the corresponding positioning protrusions 112 and the positioning holes 122, thereby preventing the first base 11 and the second base 12 from moving relative to each other.

[0039] Furthermore, the multiple positioning holes 122 are arranged in an array, and the distance between two adjacent positioning holes 122 is set differently between adjacent rows. Since the shape and size of the first base 11 and the second base 12 are relatively similar, by setting the hole spacing of the two rows differently, alignment errors can be better avoided, thus preventing the first base 11 and the second base 12 from being installed in the wrong direction.

[0040] In one embodiment, the auxiliary connecting fixture 100 for the endoscope capillary and the curved section may further include multiple auxiliary pads. When the endoscope model changes, the diameter of the corresponding curved section 300 can change accordingly. Therefore, one or more of the auxiliary pads can be stacked between the first base 11 and the second base 12, and the first auxiliary pad is provided with a receiving groove. Each receiving groove can be accommodated in the corresponding first limiting groove 111 and second limiting groove 121. The diameters of the receiving grooves on the multiple auxiliary pads can be progressively set. Two auxiliary pads with receiving grooves of the same diameter are placed on the corresponding first base 11 and second base 12, and the two receiving grooves together form the mounting hole. The diameter of the mounting hole can be adjusted according to the different sizes of the receiving grooves of the auxiliary pads, so that the mounting hole can be matched with welding limiting rods of different diameters to meet the connection requirements of different curved sections 300, thus expanding the applicability.

[0041] In another embodiment, a plurality of first limiting grooves 111 may be provided on the first seat 11, and the plurality of first limiting grooves 111 may be arranged at intervals along the front-back direction; a plurality of second limiting grooves 121 may be provided on the second seat 12, and the plurality of second limiting grooves 121 may be arranged at intervals along the front-back direction and may correspond one-to-one with the plurality of first limiting grooves 111.

[0042] The diameters of the multiple first limiting grooves 111 can be set in the same way, so that the auxiliary connecting fixture 100 for the endoscope capillary and the bending section can simultaneously perform multiple sets of capillary 200 and bending section 300 connection operations, which is more efficient.

[0043] In another embodiment, the diameters of the plurality of first limiting grooves 111 are set differently, and the diameters of the plurality of second limiting grooves 121 are also set differently, thereby making the auxiliary connecting fixture 100 for the endoscope capillary and the curved section more adaptable to the connection requirements of capillary 200 and curved section 300 of different sizes.

[0044] Specifically, the orientation structure 2 includes a welded liner 21, which passes through the mounting hole, with one end protruding from the first end to accommodate the bent section 300, and the other end flush with the second end. The welded liner 21 is generally cylindrical and conforms to the shape of the mounting hole to be engaged within it.

[0045] Combination Figure 4 and Figure 5 As shown, when the directional base 1 includes a first base 11 and a second base 12, the welding liner 21 includes a first rod 211 and a second rod 212 arranged opposite to each other. The first rod 211 is accommodated in and adapted to the first limiting groove 111, and the second rod 212 is accommodated in and adapted to the second limiting groove 121. During assembly, the first rod 211 can be fixed in the first limiting groove 111, and the second rod 212 can be fixed in the second limiting groove 121. Then, the first base 11 and the second base 12 can be connected, fixing the relative positions of the first rod 211 and the second rod 212, thus ensuring more accurate alignment with the bent section 300 when inserting the capillary tube 200.

[0046] Furthermore, at least one directional channel is defined between the welding liner 21 and the mounting hole. Each directional channel extends along a first direction of the directional base 1, and each directional channel is adapted to allow a capillary tube 200 to pass through it. When multiple traction ropes are correspondingly provided in the curved section 300, multiple capillary tubes 200 are also provided. By defining multiple directional channels between the welding liner 21 and the mounting hole, it is ensured that multiple capillary tubes 200 can all pass into the curved section 300 under the guidance of the directional channels and abut against the buckles 302 in the curved section 300. Specifically, each capillary tube 200 can extend into the buckle hole of the buckle 302.

[0047] Preferably, combined with Figure 4 and Figure 5 As shown, when two capillary tubes 200 are provided, a first clearance groove 2111 is provided on the side of the first rod 211 facing away from the opening of the first limiting groove 111. The first clearance groove 2111 extends along the first direction to define a directional channel between itself and the first limiting groove 111. A second clearance groove 2121 is provided on the side of the second rod 212 facing away from the opening of the second limiting groove 121. The second clearance groove 2121 extends along the first direction to define another directional channel between itself and the second limiting groove 121. The two directional channels can guide the two capillary tubes 200 respectively to ensure the relative position of the two capillary tubes 200 and to allow the two capillary tubes 200 to better engage with the corresponding buckles 302.

[0048] Of course, when the type of endoscope is different and the bending direction of the corresponding curved section 300 is more diverse, the number of corresponding guide channels will also change accordingly. For example, when four traction ropes are set to pull the curved section 300, the number of corresponding capillary tubes 200 is also four. Four clearance grooves can be evenly spaced on the circumference of the welding rod 21, and the opening of each clearance groove faces the inner wall of the mounting hole, forming the directional channel between each clearance groove and the inner wall of the mounting hole. The arrangement of the welding rod 21 is more flexible and diverse. Moreover, setting the welding rod 21 as a first rod body 211 and a second rod body 212 makes it easy to replace the first rod body 211 and the second rod body 212 when the size of the corresponding first limiting groove 111 and the second limiting groove 121 changes, without having to replace the entire directional base 1, which is cheaper and more convenient to use.

[0049] In one embodiment, the auxiliary connecting fixture 100 for the endoscope capillary and the curved section further includes a length measuring element for identifying the length of the capillary extending from the second end of the directional channel. Specifically, the length measuring element 3 is used to obtain the length of the capillary 200 extending from the left end of the mounting hole, thereby determining the retention length of the capillary 200. Preferably, combined with Figure 2 , Figure 4 and Figure 5 As shown, the length measuring component 3 includes a first scale 31 protruding from the second end of the first base 11 and a second scale 32 protruding from the second end of the second base 12. The first scale 31 is located on one side of the first limiting groove 111, and the second scale 32 is located on one side of the second limiting groove 121, with the first scale 31 and the second scale 32 arranged opposite to each other. Preferably, the first scale 31 and the second scale 32 are located on the left side of the orientation base 1, and are arranged opposite to each other in the vertical direction. On the one hand, the two scales can refer to each other to ensure the accuracy of the measurement; on the other hand, when two capillary tubes 200 are provided, the first scale 31 and the second scale 32 can be used to measure the two capillary tubes 200 respectively, which is more efficient.

[0050] The length measuring element 3 can be configured in ways including, but not limited to, those described above. In other embodiments, the length measuring element 3 can also be configured as an electronic ruler or a scale marker. For example, a marking plate is provided on the left side of the orientation base 1. When corresponding to a biliary or pancreatic endoscope, a marking line #1 is engraved on the marking plate; when corresponding to a gastrointestinal endoscope, a marking line #2 is engraved on the marking plate. In turn, corresponding markings can be made for different endoscopes to indicate the length position of the left end of the corresponding capillary 200, thus marking the cutting position more intuitively and clearly.

[0051] Preferably, the first scale 31 is integrally formed with the first base 11, and the second scale 32 is integrally formed with the second base 12. This ensures a more precise relative position between the first scale 31 and the second scale 32 and the orientation base 1, thereby improving the accuracy of the measurement of the capillary 200. Furthermore, the scale values ​​of the first scale 31 and the second scale 32 are consistent. The starting scale of the first scale 31 and the second scale 32 can begin from the left end face of the orientation base 1, or it can begin from the right end face of the orientation base 1, ensuring a fixed reference starting surface.

[0052] Of course, in other embodiments, the length measuring element 3 can also be detachably mounted on the orientation base 1. Specifically, the length measuring element 3 can be configured as multiple scale bars of different lengths. Each scale bar can be screwed, magnetically attached, or snapped onto the left side of the orientation base 1, similar to the principle of the marking plate described above. Different scale bars correspond to different models of endoscopes, thereby calibrating the length of the capillary tube.

[0053] Moreover, such as Figure 6 As shown, a first anti-misalignment protrusion 113 protrudes from one side of the first base 11, and a second anti-misalignment protrusion 123 protrudes from one side of the second base 12. The first anti-misalignment protrusion 113 and the second anti-misalignment protrusion 123 are located on the same side and are relatively fitted together to be suitable for locking into the slot of the curved section 300. Preferably, both the first anti-misalignment protrusion 113 and the second anti-misalignment protrusion 123 protrude from the right side of the orientation base 1. During the assembly of the first base 11 and the second base 12, the relative orientation of the first base 11 and the second base 12 can be found more quickly through the first anti-misalignment protrusion 113 and the second anti-misalignment protrusion 123, thereby improving assembly efficiency. Figure 3 and Figure 6 As shown, a slot is provided on one side of the left end of the snake tube 301. When installing the bent section 300, the side with the slot can be locked onto the outside of the first anti-fooling protrusion 113 and the second anti-fooling protrusion 123 to align the bent section 300 in the circumferential direction, thereby ensuring that the capillary tube 200 can better abut against the buckle 302 of the bent section 300 when it is inserted into the bent section 300.

[0054] An assembly process for a curved section 300 and a capillary tube 200, using an auxiliary connecting fixture 100 for connecting the endoscopic capillary tube and the curved section, specifically includes the following steps:

[0055] S100, providing an auxiliary connecting fixture 100 and a bending section for the endoscope capillary and bending section, and a bending section 300, fixing one end of the bending section 300 to one end of the orientation structure 2 that protrudes from the mounting hole;

[0056] S200: Provide multiple capillaries 200, and insert each capillary 200 into a plurality of directional channels of the auxiliary connecting fixture 100 for the endoscope capillaries and the curved section, such that each capillary 200 passes from the second end of the mounting hole toward the first end, and after each capillary 200 passes out of the mounting hole from the first end, it passes into the curved section 300 and abuts against the corresponding snap 302 end of the curved section 300;

[0057] S300, Observation length measuring component 3, cuts the length of the second end of the capillary tube 200 protruding from the mounting hole according to the preset length;

[0058] S400, welded capillary tube 200 and bending section 300.

[0059] In this embodiment, when assembling the curved section 300 and the capillary tube 200, specifically, taking the example of having two capillary tubes 200, we will explain in detail. First, one end of the snake tube 301 of the curved section 300 is sleeved on the right side of the directional structure 2 that protrudes from the mounting hole. Specifically, the snake tube 301 is sleeved on the outside of the first rod 211 and the second rod 212, and the side of the snake tube 301 with the slot is engaged with the side of the auxiliary connecting fixture 100 for the endoscope capillary tube and the curved section with the first anti-foolproof protrusion 113 and the second anti-foolproof protrusion 123. On the one hand, this can limit the insertion depth of the snake tube 301 on the first rod 211 and the second rod 212, and on the other hand, it can limit the circumferential orientation of the snake tube 301 during installation. After the curved section 300 is installed in place, two capillary tubes 200 are installed one by one. Each capillary tube 200 is inserted from left to right into the directional channel of the auxiliary connecting fixture 100 for endoscope capillary tubes and curved sections. After each capillary tube 200 protrudes from the right end of the mounting hole, it is continuously inserted until the right end of the capillary tube 200 can no longer be moved forward, indicating that the capillary tube 200 has abutted against the buckle 302 and has been installed in place. After multiple capillary tubes 200 are installed in place, the length of the left end of the capillary tube 200 protruding from the mounting hole is measured so that the capillary tube 200 can be cut to the preset length. Finally, the part of the capillary tube 200 located inside the curved section 300 is welded to the curved section 300, thereby completing the assembly of the curved section 300 and the capillary tube 200.

[0060] Furthermore, after step S400, the following steps may also be included:

[0061] The auxiliary connecting fixture 100 for the endoscope capillary and the curved section is moved along the second end of the mounting hole toward the first end, so that the auxiliary connecting fixture 100 for the endoscope capillary and the curved section is pulled out from the assembled product of the curved section 300 and the capillary 200.

[0062] After the curved section 300 and the capillary tube 200 are assembled, when disassembling the auxiliary connecting fixture 100 for the endoscope capillary tube and the curved section, it is only necessary to move the auxiliary connecting fixture 100 for the endoscope capillary tube and the curved section from the second end toward the first end of the mounting hole, that is, from the left, to pull out the auxiliary connecting fixture 100 for the endoscope capillary tube and the curved section. The assembled product of the curved section 300 and the capillary tube 200 is easier to remove and the operation is more convenient. Moreover, without disassembling the auxiliary connecting fixture 100 for the endoscope capillary tube and the curved section, the next assembly procedure can be entered more quickly, resulting in higher assembly efficiency.

[0063] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
