Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely is a kind of needle for hysteroscopy injection and needle array for hysteroscopy injection. BACKGROUND

[0002] In the current medical field, for uterine cavity adhesion and other diseases, treatment means includes hysteroscopy drug injection or stem cell multi-point injection. However, the injection needle used in the existing technology under the hysteroscope is a single needle design, which means that each operation can only puncture one part. When facing extensive lesions in the uterine cavity, multiple punctures are required. The disadvantages of single needle injection are highlighted. On the one hand, only one puncture can be made at a time, and the entire injection process takes a long time, increasing the risk of complications such as water intoxication. On the other hand, the puncture spacing is difficult to accurately control, which easily leads to uneven distribution of drugs, and some parts are overdosed, while some parts are even missed.

[0003] The needle array technology can theoretically effectively solve the above problems, but in actual application, new problems have arisen. During hysteroscopy operation, instruments can only be inserted through a relatively narrow channel. If the size of the needle array is too large, it will be difficult to reach the uterine cavity. If a larger cervical dilator is used to dilate the cervix to obtain a larger surgical access, it can meet the instrument access requirement, but it will cause damage to the cervix, thereby increasing the risk of cervical insufficiency in future pregnancy. SUMMARY

[0004] To solve the problems existing in the prior art, the utility model provides a needle for hysteroscopy injection and a needle array composed of the needle for hysteroscopy injection.

[0005] The needle for hysteroscopy injection provided by the utility model comprises a long strip-shaped base, a plurality of needle tubes are arranged along the axial direction of one side of the long strip-shaped base at intervals, a liquid passing channel communicating with each needle tube is arranged in the long strip-shaped base, the liquid passing channel is connected with a syringe through a liquid infusion catheter, and grooves facilitating the gripping of forceps are arranged on the two symmetrical sides of the long strip-shaped base.

[0006] Further, the number of needle tubes is three, the three needle tubes are all communicated with the same liquid passing channel arranged in the long strip-shaped base, and are connected with the same syringe.

[0007] Further, the number of needle tubes is three, and three liquid passing channels communicating with the three needle tubes are arranged in the long strip-shaped base, and correspondingly connected with three different syringes.

[0008] Further, the infusion catheter connected with the long strip base is one, and three independent liquid passing channels are arranged in the infusion catheter, one end of the three independent liquid passing channels is connected with the three liquid passing passages on the long strip base respectively, and the other end is connected with three different syringes.

[0009] The hysteroscope injection needle array provided by the utility model has the advantages that the hysteroscope injection needle array comprises two or more hysteroscope injection needles, and the hysteroscope injection needle is provided with a magnet piece on the opposite two sides.

[0010] The hysteroscope injection needle array provided by the utility model has the advantages that the hysteroscope injection needle array comprises two or more hysteroscope injection needles, and the hysteroscope injection needle is provided with a magnet piece on the opposite two sides.

[0011] (1) Compared with the traditional single needle which can only puncture one part at a time, the hysteroscope injection needle array provided by the utility model is provided with multiple needle tubes, and can puncture and administer drugs to multiple parts at a time, for example, when the number of needle tubes is three, the injection of three parts can be completed in a short time, the injection time required for treating extensive lesions in the uterine cavity is greatly shortened, and the risk of complications such as water poisoning is significantly reduced; the multiple needle tubes can be arranged at an interval according to the predetermined interval, and then punctured according to the predetermined interval, so that the drugs can be more evenly distributed in the lesion part, the situation that some parts are administered too much and some parts are administered too little or missed due to the difficulty in grasping the puncture interval is avoided, and the treatment effect is improved; the grooves arranged on the two opposite sides of the long strip base facilitate the grasping of the hysteroscope, and help the doctor to pull out the needle after the injection is completed;

[0012] (2) The hysteroscope injection needle array provided by the utility model not only provides the mode that multiple needle tubes are connected with the same liquid passing passage and connected with the same syringe, but also is provided with the design that three liquid passing passages are connected with three different syringes, and the diversified design enables the doctor to flexibly select the appropriate administration mode according to the actual condition and treatment requirement, and meets the individualized treatment requirement of different patients;

[0013] (3) The hysteroscope injection needle array provided by the utility model is arranged in the hysteroscope in the form of combination, the needle head with a smaller cross section is arranged first, and then the needle head with a larger cross section is arranged, so that the expansion injury of the cervix caused by the large instrument is avoided, and the risk of cervical insufficiency of the patient in the future pregnancy is reduced;

[0014] (4) In actual operation, the smaller cross-section of the plurality of needle tubes is inserted into the uterine cavity, compared with the overall insertion of the larger needle array, the difficulty is greatly reduced, because the cross-section of the single needle is small, it is easier to pass through the narrow channel of the hysteroscope, after entering the uterine cavity, they can be automatically combined into a larger needle array through magnetic attraction, this process does not need the doctor to perform complex manual splicing operation in the uterine cavity, simplifies the operation process, saves the operation time; in the uterine cavity, through magnetic attraction, the needles can be accurately adsorbed to the appropriate position according to the preset magnetic force direction and magnetic pole characteristics, ensuring the accuracy and stability of the needle array in the combination process; according to the specific condition of the patient, the appropriate needle array model and the administration mode can be selected, to ensure the safety and effectiveness of the treatment.
