Description

Technical Field

[0001] The utility model relates to the technical field of lacrimal duct flushing equipment, in particular to a lacrimal duct flushing kit. Background Art

[0002] Tear duct irrigation is a technique that injects liquid into the tear duct to clear blockages in different parts of the tear duct. It can check the tear duct secretions and keep the tear duct open. It is also suitable for traumatic tear duct obstruction, chronic dacryocystitis and acute dacryocystitis. It is a treatment method as well as a diagnostic method.

[0003] The existing lacrimal punctum dilator and lacrimal duct flushing needle are separate. The lacrimal punctum needs to be dilated with the lacrimal punctum dilator before the flushing needle is used. During the process of pulling out the dilator after use, the originally enlarged lacrimal punctum will quickly shrink back, and repeated operations are required to keep the lacrimal punctum enlarged, which not only increases the pain of the patient, but also increases the workload and working hours of the nurses, and is likely to cause edema and damage to the patient's eye tissue, which is very inconvenient. Utility Model Content

[0004] Based on the above description, the utility model provides a lacrimal duct flushing kit to solve the problem that the existing lacrimal point dilator and lacrimal duct flushing needle are used separately, which is time-consuming and labor-intensive and easily causes additional pain to the patient during treatment.

[0005] The utility model provides a technical solution to the above-mentioned technical problem as follows: a lacrimal duct flushing kit, comprising a flushing needle, a rotatable adjusting part is arranged inside the flushing needle, a cross groove is provided in the center of the surface of the adjusting part, an internal threaded ring is arranged on the inner side of the flushing needle, an expansion component plugged into the cross groove is installed inside the internal threaded ring, the adjusting part controls the expansion component to move vertically in a threaded connection by rotation, and cooperates with the tip of the flushing needle to perform a screwing-in and screwing-out operation.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, one end of the flushing needle is conical, an annular groove is provided at the end with a larger inner diameter of the flushing needle, and the internal threaded ring is installed at the end with a smaller inner diameter of the flushing needle.

[0008] Furthermore, the adjusting member is composed of a sleeve and a positioning plate, the sleeve is installed in the annular groove, and one end of the sleeve away from the internal thread ring extends to the outside of the flushing needle, and the positioning plate is installed on the inner side of the sleeve near one end of the internal thread ring.

[0009] Furthermore, the cross groove is opened through the center of the surface of the positioning plate, and the edges of the positioning plate and the surface of the internal thread ring are both provided with guide holes.

[0010] Furthermore, the expansion assembly is composed of a cross rod and an expander, a thread groove is provided in the center of the expander surface, the expander is threadedly connected to the internal thread ring through the thread groove, and the diameter of the expander at one end away from the internal thread ring is tapered and gradually decreases.

[0011] Furthermore, the end of the expander away from the sleeve is spherical and is inserted into the end of the inner wall of the flushing needle away from the sleeve. The spherical end of the expander extends to the outside of the flushing needle. The cross rod is arranged in the center of the expander away from the spherical end and is inserted into the cross groove.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model cooperates with a cross rod and an expander through a positioning plate, a cross groove and a threaded ring. The plug-in assembly of the cross rod and the cross groove can enable the positioning plate to drive the cross rod and the expander to rotate under force. When the expander rotates and moves vertically through the threaded connection with the internal threaded ring, the cross rod can move in contact with the inner wall of the cross groove without affecting the vertical movement of the expander. The staff only needs to control the rotation of the sleeve to control the expander to move vertically when the flushing needle is flushed. When the expander cooperates with the flushing needle to be screwed out, the flushing needle can be directly inserted into the lacrimal point together with the expander, and can be subsequently re-introduced into the flushing needle by rotating the expander, and the flushing needle can be retained in the lacrimal point for subsequent operations. There is no need to reuse the expander during the process, which is convenient for the staff to operate and use, reduces the treatment time of the patient, and reduces the pressure on the patient and the staff.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] See also Figure 1-5 The utility model discloses a lacrimal duct flushing kit, comprising a flushing needle 1, a rotatable adjusting member is arranged inside the flushing needle 1, a cross groove 31 is provided at the center of the surface of the adjusting member, an internal thread ring 5 is arranged on the inner side of the flushing needle 1, an expansion component plugged into the cross groove 31 is installed inside the internal thread ring 5, the adjusting member controls the expansion component to move vertically in a threaded connection manner by rotation, and cooperates with the tip of the flushing needle 1 to perform a screwing operation.

[0024] See also Figure 1 One end of the flushing needle 1 is tapered, an annular groove 11 is provided at the end with a larger inner diameter of the flushing needle 1, and the internal thread ring 5 is installed at the end with a smaller inner diameter of the flushing needle 1.

[0025] See also Figure 4 The adjusting member is composed of a sleeve 2 and a positioning plate 3. The sleeve 2 is installed in the annular groove 11, and the end of the sleeve 2 away from the internal thread ring 5 extends to the outside of the flushing needle 1. The sleeve 2 is used to connect the syringe. After the sleeve 2 is connected to the syringe, it can still rotate in the annular groove 11 without affecting the use. The positioning plate 3 is installed on the inner side of the sleeve 2 near the end of the internal thread ring 5. The cross groove 31 is opened in the center of the surface of the positioning plate 3. The edges of the positioning plate 3 and the internal thread ring 5 are provided with guide holes 7. The setting of the guide hole 7 enables the flushing liquid to flow normally in the flushing needle 1 after the expander 6 and other structures are installed inside the flushing needle 1.

[0026] See also Figure 1The expansion assembly is composed of a cross rod 4 and a dilator 6. A thread groove 61 is provided in the center of the surface of the dilator 6. The dilator 6 is threadedly connected to the internal thread ring 5 through the thread groove 61. The diameter of the end of the dilator 6 away from the internal thread ring 5 is tapered and gradually reduced. The end of the dilator 6 away from the sleeve 2 is spherical and inserted into the end of the inner wall of the flushing needle 1 away from the sleeve 2. The spherical end of the dilator 6 extends to the outside of the flushing needle 1. When the spherical end of the dilator 6 extends to the outside of the flushing needle 1, it can be matched with the conical end of the flushing needle 1. When in use, the spherical end of the dilator 6 can be inserted into the patient's lacrimal point together with the conical end of the flushing needle 1. The cross rod 4 is set in the center of the dilator 6 away from the spherical end and is inserted in the cross groove 31. The connection between the cross rod 4 and the cross groove 31 can drive the cross rod 4 and the expander 6 to rotate when the sleeve 2 rotates. After the expander 6 rotates, it can be vertically lifted and lowered through the threaded connection between the thread groove 61 and the internal thread ring 5. The lifting process will drive the cross rod 4 to move in line with the inner wall of the cross groove 31. The connection between the cross rod 4 and the cross groove 31 plays a transmission role in the rotation of the expander 6, and does not affect the lifting and lowering activities of the expander 6. When the spherical end of the expander 6 can be inserted into the patient's lacrimal point together with the tapered end of the flushing needle 1, the expander 6 can be removed from the lacrimal point by adjusting the lifting and lowering method of the expander 6, and the flushing needle 1 is retained in the lacrimal point to facilitate subsequent lacrimal duct flushing. The expander 6 does not need to be reused during the process.

[0027] When it is necessary to insert the flushing needle 1 into the patient's lacrimal point, first rotate the sleeve 2. The positioning plate 3 in the sleeve 2 is connected to the cross rod 4 through the cross groove 31, driving the dilator 6 to rotate in the internal threaded ring 5, and the dilator 6 is moved toward the tapered end of the flushing needle 1 through a threaded connection. During the process, the cross rod 4 also slides against the inner wall of the cross groove 31 while rotating, until the spherical end of the dilator 6 extends to the outside of the flushing needle 1 and matches the tapered end of the flushing needle 1. Then, the spherical end of the dilator 6 and the tapered end of the flushing needle 1 are inserted into the patient's lacrimal point together. Then, rotate the sleeve 2 in the opposite direction to drive the dilator 6 to rotate, so that it is re-entered into the flushing needle 1 through a threaded connection with the internal threaded ring 5, and the tapered end of the flushing needle 1 is retained in the lacrimal point.
