Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a B-ultrasound puncture device for assisting in maintaining the imaging in the plane of a puncture needle. Background Art

[0002] With the popularization of ultrasound equipment, clinical medical staff use ultrasound to carry out visualization work; this includes ultrasound-guided puncture technology. In ultrasound-guided puncture technology in the field of vascular access, although ultrasound is used, the position of the puncture needle cannot be observed; the effect of ultrasound-guided puncture technology is to ensure that the position of the needle or needle tip can be seen under ultrasound; ultrasound-guided puncture is generally divided into two methods: in-plane puncture and out-of-plane puncture. In the field of vascular access, both puncture technologies have applicable scenarios;

[0003] Out-of-plane puncture is along the radial direction of the puncture needle. The puncture needle is perpendicular to the ultrasound imaging plane and is outside the ultrasound imaging plane, showing the short axis or cross-section of the blood vessel. The probe is fanned from the needle body to the needle tip, and the moment when the bright spot at the needle tip disappears is the needle tip position point.

[0004] In-plane puncture is along the axial direction of the puncture needle. The puncture needle is parallel to the ultrasound imaging plane and is in the ultrasound imaging plane, showing the long axis or longitudinal section of the blood vessel. The position of the needle tip can be statically observed in the plane. The real-time position of the needle tip or even the entire needle body can be statically observed in the plane.

[0005] In summary, the following technical problems exist in the process of keeping the puncture needle in the B-ultrasound puncture plane: although the shell thickness of the ultrasound probe is about 1 cm, the thickness of the sound beam emitted by the probe is about 0.01 mm, which requires high operating precision. If it is a shallow puncture, that is, the puncture target is within 3 cm below the skin, the in-plane development can be well controlled, but in deep puncture, that is, the puncture target is more than 4 cm below the skin, inexperienced doctors cannot find it after the needle enters. Currently, this mainly occurs in deep vascular puncture and ultrasound-guided blockade of deep nerves in obese patients; during the puncture process, the plane where the puncture needle is located needs to be kept within the plane range of ultrasound development, and the puncture needle needs to be adjusted during puncture, and the angle and position need to be changed, the development of the puncture needle needs to be readjusted, and it is not easy to operate and align, which affects the surgical operation. Utility Model Content

[0006] In view of the above problems existing in the prior art, the utility model provides a B-ultrasound puncture device which assists in maintaining the imaging in the plane of the puncture needle.

[0009] Furthermore, a vertical wide groove is longitudinally arranged in the middle of the side frame, and the width of the vertical wide groove is greater than the outer diameter of the limiting tube; this enables the operator to adjust the puncture plane of the puncture needle in a small range, so that the puncture needle has a clearer development effect under the optimal ultrasonic feedback; horizontal narrow grooves are opened on the front and back sides of the side frame, and the horizontal narrow grooves cooperate with the positioning assembly; this enables the puncture needle to keep the puncture plane unchanged relative to the ultrasonic development range with the assistance of the limiting part.

[0010] Furthermore, the positioning assembly includes a rotating rod, which is fixedly connected to both sides of the limiting cylinder, and the rotating rod is horizontally slidably connected to the transverse narrow groove.

[0011] Furthermore, the positioning assembly also includes a rotating sleeve, the rotating rod is provided with a thread, the rotating sleeve is provided with a threaded hole, and the rotating sleeve is threadedly connected to the thread of the rotating rod through the threaded hole; the cooperation between the rotating sleeves on both sides and the side frames ensures that the rotating cylinder will not rotate around the axis, thereby ensuring that the puncture plane of the puncture needle in the syringe is within the ultrasonic imaging range, and at the same time controlling the abutment between the rotating sleeve and the side frame. In the non-abutment state, it can move at any time within the puncture plane of ultrasonic imaging, change the angle, position, etc., and can maintain a stable relative position with the ultrasonic probe after abutment.

[0012] Furthermore, the main frame is fixedly connected with a clamping frame on the inner side of both ends to cooperate with the ultrasonic probe to avoid slipping.

[0013] Furthermore, an anti-sliding block is fixedly connected to the rotating sleeve.

[0014] Furthermore, the tightening knob is fixedly connected with a tightening pad in the main frame to avoid damaging the ultrasonic probe.

[0015] Beneficial effects of the utility model:

[0016] The invention discloses a B-ultrasound puncture device for assisting in maintaining the imaging within the plane of a puncture needle.

[0031] Example 1

[0032] like Figure 1-9 Shown

[0034] A vertical wide groove (201) is longitudinally arranged in the middle of the side frame (2), and the width of the vertical wide groove (201) is greater than the outer diameter of the limiting tube (3); so that the operator can adjust the puncture plane of the puncture needle in a small range, so that the puncture needle has a clearer imaging effect under the best ultrasonic feedback; the front and rear sides of the side frame (2) are provided with horizontal narrow grooves (202), and the horizontal narrow grooves (202) cooperate with the positioning component; so that the puncture needle can keep the puncture plane unchanged relative to the ultrasonic imaging range with the assistance of the limiting part;

[0035] The positioning assembly comprises a rotating rod (301), the rotating rod (301) is fixedly connected to two sides of the limiting cylinder (3), and the rotating rod (301) is horizontally slidably connected in a transverse narrow groove (202);

[0036] The main frame (1) is fixedly connected to a clamping frame (102) on the inner sides of both ends; the tightening knob (110) is fixedly connected to a tightening pad (112) inside the main frame (1) to avoid damaging the ultrasonic probe.
