DETAILED DESCRIPTION

[0032] The utility model will be further described below in conjunction with the accompanying drawings.

[0033] Reference Figure 1-6 As shown, a post-ERCP nasobiliary duct fixing and tidying device of the present embodiment includes a fixing seat 1, a fixing cover 2 and an elastic member 3. The fixing seat 1 includes a base plate 11, a front stopper 12, a rear stopper 13, a first articulated seat 14 and a connecting seat 15. The front stopper 12, the rear stopper 13 and the first articulated seat 14 are all fixed on the upper side of the base plate 11. The front stopper 12 and the first articulated seat 14 are respectively located at the front and rear ends of the base plate 11, and the rear stopper 13 is located between the front stopper 12 and the first articulated seat 14.

[0034] The front block 12 specifically includes a front block middle section 121 and a front block horizontal section 122. The front block horizontal section 122 is located above the bottom plate 11 and parallel to the bottom plate 11. The upper and lower sides of the front block middle section 121 are respectively connected to the front block horizontal section 122 and the bottom plate 11. A locking groove 123 is provided at the rear end of the front block horizontal section 122. Specifically, the locking groove 123 includes a locking rod groove 1231 and a boss groove 1232. There are two boss grooves 1232, which are respectively provided at the front of the left and right walls of the locking rod groove 1231.

[0035] The connection seat 15 is arranged at the lower side of the bottom plate 11. In this embodiment, the connection seat 15 has an assembly hole that runs through the left and right sides. A thin groove that is connected to the assembly hole is also opened at the rear of the side wall of the connection seat 15. The height of the thin groove is slightly smaller than the diameter of the pin fixing rod. The upper and lower edges of the outer side of the thin groove are also chamfered to provide guidance for the pin fixing rod to enter. When assembling the pin, align the pin fixing rod with the opening on the outer side of the thin groove, and then press the fixing rod to one side of the assembly hole so that it overcomes the elastic force of the connection seat 15 and is inserted into the assembly hole. In this way, the pin is assembled with the fixing and arranging device, and the fixing and arranging device can be pinned to the patient's clothes through the pin later.

[0036] In this embodiment, the fixed cover 2 includes a hinged cover 21 and a sliding cover 22. The sliding cover 22 is slidably connected to the hinged cover 21. Specifically, the hinged cover 21 includes a first cover plate 211 and a second hinge seat 212 connected to the first cover plate 211. The first cover plate 211 is provided with a strip-shaped slide groove 2111 that runs through the left and right sides. The sliding cover 22 includes a second cover plate 221 and a support rod 222. The number of the support rods 222 is two. The two support rods 222 are fixed to the rear end of the second cover plate 221. The front part of the first cover plate 211 is assembled between the two support rods 222. Two slide rods 2221 that run through the strip-shaped slide groove 2111 are fixed between the two support rods 222. In this way, the sliding cover 22 and the hinged cover 21 can be slidably connected.

[0037] The sliding cover 22 also has a locking piece 223 matching the locking groove 123 at one end away from the hinged cover 21, and the locking piece 223 is arranged at the front end of the second cover plate 221. Specifically, the locking piece 223 includes two locking bolts 2231 symmetrically distributed on the left and right, and the locking bolt 2231 includes a locking rod 22311 and a boss 22312. The boss 22312 is fixed to the front end of the locking bolt 2231, and the bosses 22312 of the two locking bolts 2231 are respectively located on the opposite sides of the two locking rods 22311, and the front end surface of the boss 22312 is a front guiding inclined surface inclined from the back to the front from the side away from the locking rod 22311 to the side close to the locking rod 22311, and the rear end surface of the boss 22312 is a rear guiding inclined surface inclined from the front to the back from the side away from the locking rod 22311 to the side close to the locking rod 22311.

[0038] In this embodiment, the upper end of the second cover plate 221 further has three strip protrusions 2211 spaced apart from each other in the front and rear directions. The strip protrusions 2211 can increase the friction coefficient of the upper end of the second cover plate 221 so that the user can push the second cover plate 221 forward and backward with fingers.

[0039] In this embodiment, the second hinge seat 212 on the hinged cover 21 is hinged to the first hinge seat 14 through the connecting shaft 4. Specifically, the first hinge seat 14 includes a first connecting ear 141, which is provided with an axial hole for accommodating the connecting shaft 4. The number of the first connecting ears 141 is two, and the two first connecting ears 141 are arranged at intervals on the left and right. The second hinge seat 212 includes a second connecting ear 2121, which is provided with an axial hole for accommodating the connecting shaft 4. The number of the second connecting ears 2121 is also two, and the two second connecting ears 2121 are arranged at intervals on the left and right. The two second connecting ears 2121 are assembled between the two first connecting ears 141, and the connecting shaft 4 is assembled in the axial holes of the two first connecting ears 141 and the two second connecting ears 2121. The connecting shaft 4 is bonded and fixed to the axial holes of the two first connecting ears 141, and is sleeved and connected to the axial holes of the two second connecting ears 2121. In this way, the fixed cover 2 can rotate relative to the fixed seat 1.

[0040] The elastic member 3 is disposed between the hinged cover 21, the bottom plate 11 and the connecting shaft 4 so that the hinged cover 21 has a tendency to flip toward the side away from the bottom plate 11. Specifically, in this embodiment, the elastic member 3 is a double-torsion torsion spring, which is sleeved on the outside of the connecting shaft 4 and located between the two second connecting ears 2121. The torsion spring has a first torsion arm 31 and two second torsion arms 32, and the first torsion arm 31 and the second torsion arm 32 are respectively in contact with the first cover plate 211 and the bottom plate 11.

[0041] In this embodiment, the first hinge seat 14 further includes a stopper 142, which is connected between the two first connection ears 141 and is located on the side of the connection shaft 4 away from the rear stopper 13. When the first cover plate 211 is flipped to the side away from the bottom plate 11 to abut against the stopper 142, the stopper 142 cannot be flipped further, so that the flip angle of the first cover plate 211 can be limited. In this embodiment, when the first cover plate 211 is flipped to abut against the stopper 142, the angle between the first cover plate 211 and the bottom plate 11 is 90 degrees.

[0042] In a natural state, the fixed cover 2 will be flipped open relative to the fixed seat 1 under the elastic force of the elastic member 3. When the user overcomes the elastic force of the elastic member 3 and flips the fixed cover 2 toward the fixed seat 1 until the hinged cover 21 abuts against the rear stopper 13, the lock member 223 will be aligned with the lock slot 123, and the sliding cover 22 can be slid toward the lock slot 123. When the two front guide inclined surfaces abut against the edges on the left and right sides of the lock rod slot 1231, the two lock rods 22311 away from the second cover plate 221 will be elastically deformed and moved closer to each other, so that the two bosses 22312 enter and make way, and after the two bosses 22312 enter the lock rod slot 1231 and align with the two boss slots 1232, the two lock rods 22311 will restore their deformation, so that the bosses 22312 are respectively stuck in the two boss slots 1232, so that the lock member 223 is locked into the lock slot 123, and the fixed cover 2 is locked on the fixed seat 1. In this state, the bottom plate 11 will be enclosed with the front stopper 12 , the sliding cover 22 , the hinged cover 21 and the rear stopper 13 to form a restrained space.

[0043] When the user pushes the sliding cover 22 backward to make it slide backward relative to the hinged cover 21, the locking rod 22311 will drive the boss 22312 to move backward until the rear guiding slope abuts against the outer edge of the rear side of the boss groove 1232. In this way, under the guiding action of the rear guiding slope, the two locking rods 22311 away from the second cover plate 221 will elastically deform and move closer to each other, so that the two bosses 22312 withdraw from the corresponding boss grooves 1232. After the locking bolt 2231 withdraws from the locking groove 123, the fixed cover 2 is released from the rotation restriction. After the user releases the fixed cover 2, the fixed cover 2 will automatically open under the elastic force of the elastic member 3, so that the constraint space can be in an open state.

[0044] When fixing and arranging the nasobiliary duct, the user uses four fingers of one hand except the thumb to hold the fixing seat 1 of the fixing and arranging device, and then uses the other hand to wind the nasobiliary duct in a serpentine shape in the opened constraint space (the thumb of the hand holding the fixing and arranging device can be used to assist in this process). The number of windings is appropriate to fill the constraint space. After the constraint space is filled, the user pushes the fixing cover 2 with the thumb to turn it down to close the constraint space, and then continues to use the thumb to push the sliding cover 22 forward to lock the fixing cover 2 and the fixing seat 1. In this way, the nasobiliary duct can be stored in a serpentine shape on the fixing and arranging device, and then the fixing and arranging device can be fixed to the patient's clothes with pins.

[0045] When the fixing and organizing device releases the nasobiliary duct, the user can still use four fingers of one hand except the thumb to hold the fixing base 1 of the fixing and organizing device, and then use the thumb to push the fixing cover 2 backwards, so that the restrained space can be quickly opened to quickly release the stored nasobiliary duct.

[0046] It is worth mentioning that the front block middle section 121 and the rear block 13 are both arc-shaped, and the inner side of the arc of the front block middle section 121 is arranged opposite to the inner side of the arc of the rear block 13. Such a setting is more beautiful and can better adapt to the round shape of the nasobiliary duct so as to more stably constrain the nasobiliary duct.

[0047] In addition, in this embodiment, the two first connecting ears 141 are both circular, and the minimum distance between the first connecting ears 141 and the rear stopper 13 is smaller than the diameter of the nasobiliary duct, so that a clamping space with wider upper and lower sides and a narrower middle can be enclosed to form, so as to quickly clamp the fixing seat 1 on the outside of the nasobiliary duct to form a temporary fixation to meet different usage conditions.

[0048] In summary, the utility model discloses a device for fixing and arranging the nasobiliary duct after ERCP surgery. The device has a simple and compact structure and can conveniently fix and arrange the nasobiliary duct. In addition, when releasing the nasobiliary duct, the release can be achieved with one hand, which is simple and convenient to operate and is conducive to market promotion and use.

[0049] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
