Because the inner wall of the cylindrical sleeve 1031 is provided with the internal thread 10311, the outer wall of the cylindrical extending portion 101 is provided with the external thread 1011 engaged with the internal thread 10311 in an outward protruding manner, when the cylindrical sleeve 1031 is rotated to enable the internal thread 10311 to engage with different positions of the external thread 1011, the front-back position of the cylindrical sleeve 1031 is adjustable, so that the distance between the front wall of the retainer 1032 and the end of the cylindrical extending portion 101 is adjustable, and thus, the position of the stop member 103 is adjustable and is convenient to fix in the front-back direction after the position is adjusted, and the stop member is not easy to shift back and forth.
Furthermore, the invention is reliable and stable in use, so that the use effect can be effectively improved.
In a preferred embodiment, the inner wall of the rear end of the cylindrical sleeve 1031 is provided with the inner edge and the inner thread 10311, the outer wall of the rear end of the cylindrical extending portion 101 is provided with a first outer edge and a second outer edge in a side-by-side manner from front to back, the first outer edge surface is provided with a first outer thread 10111 engaged with the inner thread, and the second outer edge surface is provided with a second outer thread 10112 engaged with the inner thread 10311;
wherein a spacing L between a rear end of the first external thread 10111 and a rear end of the second external thread 10112 is 2.0cm;
when the internal thread 10311 is fully engaged with the first external thread 10111, the front wall of the retainer 1032 is flush with the front end of the cylindrical extension 101; when the female screw 10311 is fully engaged with the second male screw 10112, a distance between the front wall of the retainer 1032 and the front end of the cylindrical protrusion 101 is 2.0cm.
Preferably, in this embodiment, the internal thread 10311 is provided with two turns, and the first external thread 10111 and the second external thread 10112 are also provided with only two turns.
As such, referring to fig. 1, when the internal thread 10311 is completely engaged with the first external thread 10111, the front wall of the retainer ring 1032 is flush with the front end of the cylindrical extension 101, so that the first step of ultrasonic inspection is facilitated; referring to fig. 2, when the internal thread 10311 is completely engaged with the second external thread 10112, a distance between a front wall of the retainer ring 1032 and a front end of the cylindrical protrusion 101 is 2.0cm, so that the second-step ultrasonic inspection is facilitated, and the second-step ultrasonic inspection is accurate in position without occurrence of a large positional deviation.
Further, in the present invention, the internal thread 10311 is provided only at the rear end of the inner wall of the cylindrical sleeve 1031, instead of providing the internal thread 10311 over the entire inner wall thereof, so that it is possible to greatly accelerate the speed of the adjustment of the position of the stopper 103 by facilitating the direct displacement thereof from the position of engagement with the first external thread 10111 to the position adjacent to the second external thread 10112 and then engaging with the second external thread 10112 after screwing the cylindrical sleeve 1031 two times.
Furthermore, the invention does not consume much energy and time to use, so that the operation is quick.
It should be noted that, in the specific implementation, a limit ring 1012 protrudes outwards from the outer wall of the rear end of the cylindrical extension portion 101;
wherein the front wall of the stop collar 1012 is flush with the rear end of the second external thread 10112.
In this way, in the first step of operation inspection, the front wall of the retainer ring 1032 of the stopper 103 is visually aligned with the end of the cylindrical protruding portion 101, and in the second step of operation inspection, the cylindrical sleeve 1031 is rotated so that the rear end of the cylindrical sleeve 1031 abuts against the front wall of the stopper 1012, so that visual inspection and estimation are not required, and the operation is time-saving.
It is further added that in practice, the cylindrical extension 101 forms an obtuse angle with the cylindrical hand-held portion 102.
In this manner, the patient lies on the ultrasound examination couch and opens the thighs to allow the lithotomy position, thereby facilitating the medical personnel to grasp the cylindrical handpiece 102 in the proper orientation to maneuver the present invention.
The outer diameter of the cylindrical insertion portion 101 is smaller than the outer diameter of the cylindrical hand-held portion 102.
Thereby, even if it is made easy to distinguish the cylindrical projecting portion 101 from the cylindrical holding portion 102, and the cylindrical holding portion 102 is made relatively thick, it is made better suited for hand holding.
Meanwhile, in the present solution, an included angle between the cylindrical extending portion 101 and the cylindrical handheld portion 102 is R;
wherein r=105 degrees to 135 degrees.
In a preferred embodiment, r=120 degrees.
Thus, when the angle R between the cylindrical insertion portion 101 and the cylindrical hand-held portion 102 is 120 degrees, it is possible to facilitate the doctor to insert the cylindrical insertion portion 101 from the patient's vaginal orifice into the patient's vagina in the most appropriate orientation.
Preferably, in this embodiment, the outer wall of the cylindrical hand-holding portion 102 is concaved inwards uniformly to form a plurality of concaves 1021 suitable for holding.
Thus, the plurality of concave parts 1021 are convenient for holding, so that the invention is not easy to slip off.
Moreover, in the specific implementation, a plurality of fixing rings 10312 adapted to be fastened and sleeved on the rubber ring at the opening of the sterile probe sleeve outside the stop member 103 are uniformly arranged on the outer wall of the cylindrical sleeve 1031 near the rear end thereof and protrude outwards.
Therefore, the rubber ring at the opening of the sterile probe sleeve is conveniently clamped and fixedly sleeved outside the invention, so that the sterile probe sleeve which is required to be used is not easy to fall off when the cylindrical extending part 101 and the stop piece 103 are included, and the invention is more convenient and humanized to use.
Furthermore, the use effect of the invention can be optimized.
It should be further appreciated that, for the above-mentioned sterile probe cover, a condom may be preferably used instead, so that the gaps between the plurality of fixing rings 10312 facilitate the fixation of the rubber ring at the opening of the condom outside the present invention, so that the present invention ensures sterility when inserted into the vagina of a patient.
And, in practice, the rounded protrusion 104 has a thickness of 1.0mm-2.0mm, and preferably 2.0mm, which is so thin that it is negligible with respect to the corresponding value of 2.0cm of the front end of the cylindrical extension into the vagina of the patient, which is prescribed in the second step of ultrasonic inspection, so that the second step of ultrasonic inspection is not affected.
Other embodiments, etc., are not illustrated herein.
In summary, the invention has the advantages of simple integral structure, easy implementation, easy operation, strong practicability, strong specificity and low manufacturing cost, and does not need to increase too much cost in the improvement of the structure and the improvement of the technology, so that the invention has very good market popularization value, and can be very popular and can be effectively popularized.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, and all changes in the equivalent structure or equivalent flow, or direct or indirect application in other related technical fields, are included in the scope of the invention.
