DETAILED DESCRIPTION

[0022] Please attend Figures 1 to 4 The utility model discloses an external fixation device for nasobiliary duct after ERCP operation, comprising a headrest 1 and a nasobiliary duct fixation assembly; the nasobiliary duct fixation assembly comprises a support rod 2, an ear clip 3 and a tube clip 31, the support rod 2 is detachably connected to the headrest 1, the ear clip 3 is connected to the end of the support rod 2 away from the headrest 1, the ear clip 3 is used to fix with the patient's ear, the tube clip 31 is arranged on the ear clip 3, and the tube clip 31 is used to clamp the nasobiliary duct. When in use, the patient lies on the headrest 1, inserts one end of the nasobiliary duct into the patient's nasal cavity, the other end of the nasobiliary duct is passed through the tube clip 31 and the ear clip 3 is clamped on the ear of one side of the patient, and the support rod 2 is supported under the ear clip 3. In this state, the nasobiliary duct can be fixed without using tape, which effectively improves the comfort of the patient.

[0023] Since the ear sizes of different patients are different, in order to meet the needs of different patients, the ear clip 3 includes a first clamping portion 32, a second clamping portion 33, and a connecting portion 34 for connecting the first clamping portion 32 and the second clamping portion 33, and the connecting portion 34 can adjust the distance between the first clamping portion 32 and the second clamping portion 33. In this embodiment, the tube clamp 31 is arranged on the outside of the first clamping portion 32 and the second clamping portion 33, and the connecting portion 34 is made of a flexible metal material. The flexible metal material can be deformed to change the distance between the two ends of the ear clip 3, thereby controlling the clamping tightness of the ear clip 3. When used, it can be adjusted according to the contour of the patient's ear, which improves the patient's comfort.

[0024] When the patient lies on the headrest 1, in order to prevent the ear clip 3 from falling off, a support rod 2 is provided to support the ear clip 3, and the ear clip 3 is threadedly connected to the top of the support rod 2 through a connector 6. One end of the connector 6 is fixedly connected to the first clamping portion 32 or the second clamping portion 33, and a thread groove 21 is provided at the top of the support rod 2, and the other end of the connector 6 is screwed into the thread groove 21. In this embodiment, the connector 6 is a connecting rod, and the connector 6 is fixedly connected to the second clamping portion 33, and the outer surface of one end of the connector 6 away from the second clamping portion 33 is provided with an external thread that matches the thread in the thread groove 21.

[0025] Please continue to see Figure 5 and Figure 6 In order to connect the support rod 2 to the headrest 1 to support the ear clip 3, the nasobiliary duct fixing assembly also includes a cross bar 5, which is vertically connected to the support rod 2. In order to limit the cross bar 5 and prevent the support rod 2 from deflecting after being connected to the cross bar, a horizontal storage groove 11 is provided on the top of the headrest 1, and flexible clamps 4 are fixed to the inner walls on both sides of the storage groove 11, and there is a spacing between the flexible clamps 4 and the storage groove 11. The two flexible clamps 4 are used to cooperate with the storage groove 11 to clamp the cross bar 5 in the storage groove 11, and the support rod 2 extends upward from the storage groove 11. The cross bar 5 and the support rod 2 can be limited by the storage groove 11, and the cross bar cannot move. At the same time, when the support rod 2 is connected to the cross bar, the bottom outer side of the support rod 2 will be clamped by the two flexible clamps 4, resulting in the support rod 2 being unable to deflect and having better stability. The flexible clamping strip 4 is provided with several groups of giving way grooves 41 for giving way to the support rod 2 extending upwardly from the storage slot 11. Several groups of giving way grooves 41 are spaced along the length direction of the flexible clamping strip 4, and each group of giving way grooves 41 includes two giving way grooves 411, and the two giving way grooves 411 are respectively provided on the opposite side of the two flexible clamping strips 4. By providing the giving way grooves 41, it is possible to prevent the flexible clamping strip 4 from bulging upward at the position where it is clamped on the support rod 2, thereby affecting the clamping effect on the support rod 2. By providing multiple groups of giving way grooves 41, the position of the support rod 2 can be adjusted according to the size of the patient's head, and the applicability is stronger. At the same time, the nasal catheter can also be closed by the flexible clamping strip 4, so that the surface of the entire headrest 1 is neater. In this embodiment, the support rod 2 is a flexible rod, so that the flexibility of the support rod 2 can be better. If there is a certain gap between the support rod 2 and the patient's face, the support rod 2 can be bent to make it better fit the patient's face, so that the nasobiliary duct on the ear clip 3 fits the patient's face, preventing the nasobiliary duct from loosening.

[0026] In order to facilitate installation, the support rod 2 is detachably connected to the cross bar 5. Specifically, a connection hole 51 is provided on the cross bar 5, which runs through the cross bar 5. The bottom of the support rod 2 is inserted into the connection hole 51, and the connection hole 51 corresponds to the position of the give way groove 41. In order to make the locking degree of the support rod 2 and the cross bar 5 stronger, the diameter of the connection hole 51 is adapted to the diameter of the support rod 2. When in use, the cross bar 5 is first placed in the storage groove 11, and the support rod 2 is inserted into the connection hole of the cross bar 5 after the patient lies down, and then the ear clip 3 is clamped to the patient's ear after the ear clip 3 is connected to the support rod 2, and finally the nasobiliary duct is clamped on the tube clamp 31. When both sides of the patient need to plug the nasobiliary duct, the same connection hole 51 can be provided at the other end of the cross bar 5, so that the support rod 2 can be inserted to fix the nasobiliary duct on the other side of the patient's face. After use, for the convenience of storage, a storage bag 12 is provided on the back side of the headrest 1. After use, the support rod 2, the ear clip 3 and the cross bar 5 can be stored in the storage bag 12 for next use.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
