Background

The ultrasonic guided puncture refers to a process of inserting a puncture needle into a lesion region through skin under ultrasonic guidance and taking out lesion tissues aiming at diseases with unknown properties, such as benign and malignant tumors, inflammations with different properties and the like. The pathological tissue 6 is taken out and clearly diagnosed through pathology and laboratory examination, which is helpful for determining the treatment direction of the next step, and has clinical practical value and wider application range. When a doctor punctures, the doctor needs to hold an ultrasonic probe to contact the body surface to find the region where the pathological change tissue is located, and the other hand punctures the puncture needle into the body surface and the pathological change tissue as much as possible according to the display of the probe. This ultrasonic puncture procedure has the following problems: after the ultrasonic probe finds the pathological tissue, the puncture needle is easy to deviate from the pathological tissue after being punctured due to poor positioning of the puncture needle, and secondary puncture is needed; especially, when a new person carries out ultrasonic puncture, the lesion tissue can be punctured even by multiple times of puncture, and the pain of the patient is increased. At present, a puncture frame is adopted to fix a puncture needle and an ultrasonic probe together for puncture work, but the puncture needle of the method is not flexible enough and is easy to generate a phenomenon of inclined puncture, and the puncture frame is complex in structure and not easy to clean, and has certain hidden health hazards due to the fact that the puncture frame directly contacts with the probe on the body surface of a human body.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model adopts the following technical scheme: a laser-guided ultrasonic puncture device comprises an ultrasonic probe, a puncture needle and a linear laser line marker, wherein the ultrasonic probe is provided with a fixed frame, the fixed frame comprises a U-shaped frame and a sealing frame, and the ultrasonic probe is arranged in the U-shaped frame; one end of the U-shaped frame is hinged with one end of the sealing frame, and the other end of the U-shaped frame is connected with the other end of the sealing frame; one side of the U-shaped frame is provided with a fixing ring, the linear laser marker is arranged in the fixing ring in a penetrating mode, the outer side of the fixing ring is provided with a target plate, and the puncture needle is leaned on the target plate.

The center lines of the mark plate and the linear laser marker are on the same plane.

The central line of the linear laser line marker and the transverse central line of the cross section of the ultrasonic probe are on the same plane.

One end of the U-shaped frame is provided with an ear plate I, one end of the sealing frame is provided with an ear plate II, and the ear plate I is fixedly connected with the ear plate II through screws.

And fastening bolts are arranged on the side wall of the fixing ring.

The utility model takes the linear laser line as the marking line and the marking plate as the puncture needle backup plate, so that the puncture point and the puncture angle can be easily found, the hand shaking or the hand slipping can be prevented, the success probability of puncture can be greatly increased, even a beginner can accurately puncture the pathological changes, and the pain of a patient can be reduced; and the fixing frame and the linear laser line marker do not contact with the skin in the whole puncture process, so that the potential safety hazard is reduced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1 to 2, a laser-guided ultrasonic puncture device comprises an ultrasonic probe 1, a puncture needle 2 and a linear laser marker 3, wherein a fixed frame 4 is arranged on the ultrasonic probe 1, the fixed frame 4 comprises a U-shaped frame 41 and a sealing frame 42, and the ultrasonic probe 1 is arranged in the U-shaped frame 41; one end of the U-shaped frame 41 is hinged with one end of the sealing frame 42, and the other end of the U-shaped frame 41 is connected with the other end of the sealing frame 42; one side of the U-shaped frame 41 is provided with a fixing ring 43, the linear laser marker 3 is arranged in the fixing ring 43 in a penetrating way, the outer side of the fixing ring 43 is provided with a target plate 44, and the puncture needle 2 is leaned on the target plate 44. When the ultrasonic probe is used, the linear laser striper 3 is fixed in the fixing ring 43, when the ultrasonic probe 1 searches for the lesion tissue 6, the linear laser striper 3 is opened, and the linear laser line 5 emitted by the linear laser striper 3 is projected on the body surface of a human body; the linear laser striper 3 inclines along with the inclination of the ultrasonic probe 1, so that the linear laser line 5 emitted by the linear laser striper 3 is always superposed from the transverse center line of the lower surface of the ultrasonic probe 1, and the linear laser line 5 can be ensured to pass through the body surface of the lesion tissue 6 detected by the ultrasonic probe 1; at this time, the lesion tissue 6 is punctured, the needle head of the puncture needle is leaned on the mark plate 44, the inclination angle of the needle head of the puncture needle is equal to the inclination angles of the linear laser marker 3 and the ultrasonic probe 1, and under the condition of ensuring the inclination angle, the linear laser line 5 is used as a guide to puncture the lesion tissue 6 below the ultrasonic probe, so that the puncture rate of the lesion tissue 6 is greatly improved.
