Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings.

In some embodiments, the G-point bent-puncture trocar needle comprises an outer sleeve and a needle 1 movably sleeved in the outer sleeve, as shown in fig. 1, a first structural diagram of the needle is shown, an injection hole 7 is formed at the top end of the needle 1, as shown in fig. 2, the first structural diagram of the outer sleeve is shown, the outer sleeve comprises a first sleeve 2 and a second sleeve 3 which are communicated with each other, an obtuse angle is formed between the first sleeve 2 and the second sleeve 3, a through hole 4 is formed at one end of the first sleeve 2 away from the second sleeve 3, an opening 5 for the needle 1 to extend into is formed at one end of the second sleeve 3 away from the first sleeve 2, one end of the first sleeve 2 away from the second sleeve 3 is blunt, wherein the outer diameter of the needle is a micro-wound diameter and can comprise a plurality of types, such as 2.0mm, 2.5mm, 3mm and the like, the first sleeve and the second sleeve are integrally formed and are made of hard materials, the injection needle is made of soft material and can be bent along with the outer sleeve after extending into the outer sleeve; in the embodiment, the outer sleeve and the injection needle are arranged, when the injection needle is used, the outer sleeve is extended into the vagina of a patient, the through hole 4 is aligned to the G point of the patient, the tail part of the injection needle is connected with the injector, medicines are pushed to the top of the injection needle, the injection needle is extended into the outer sleeve, the medicine outlet of the injection needle extends out of the through hole, and the injection can be carried out at the moment; therefore, the inner wall of the vagina of the patient can be prevented from being punctured by mistake in the process of extending the injection needle into the vagina of the patient.

In some embodiments, as shown in fig. 4, a second structural schematic diagram of the outer sleeve is shown, an external thread 6 is provided at an opening of the second sleeve 3, as shown in fig. 3, a second structural schematic diagram of the injection needle is shown, a needle holder 8 is communicated with a bottom end of the injection needle 1, an annular groove is provided on an end surface of the needle holder 8 close to the injection needle 1, and an internal thread 9 screwed with the second sleeve 3 is provided in the annular groove; wherein, set up the external screw thread through the lateral wall at the second sheathed tube to set up the ring channel that has the internal thread on the needle file of syringe needle, can be connected syringe needle and second sleeve, it is more firm during the injection, it is more convenient to operate.

In some embodiments, as shown in fig. 4 and 5, which illustrate the structural schematic diagram of the outer sleeve second, the external thread 6 of the second sleeve 3 is further provided with a scale 10; the scale is arranged at the external thread of the second sleeve, so that the length of the injection needle extending into the outer sleeve can be controlled, and the depth of the injection needle inserted into the G point of the patient can be controlled more accurately.

The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by the teaching of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
