the puncture needle 3 is clamped with the rotating part, and the puncture needle 3 is arranged on a central plane parallel to the length direction of the cylinder wall of the seat cylinder 21.

By last, through with pjncture needle joint on rotating the piece, rotate the piece through rotating and adjust the angle that the pjncture needle pierces the target blood vessel to make pjncture needle get into the center of target blood vessel, improve puncture efficiency and degree of accuracy, reduce patient's misery.

Preferably, a locking assembly for locking the ultrasonic probe 1 is provided at an opposite side to a side where the projecting arm 22 is provided.

Preferably, the locking assembly comprises a stud 26 passing through the housing 21, and a clamping plate 27 fixedly connected to the end of the stud 26 passing through the housing 21.

Therefore, the ultrasonic probe is placed in the wall cylinder of the clamping plate and the seat cylinder, the stud is manually screwed, the clamping plate is forced to approach the ultrasonic probe, and the ultrasonic probe is clamped to prevent the ultrasonic probe from moving relative to the seat cylinder.

Preferably, the rotating part is provided with a clamping groove 24, and the puncture needle 3 is arranged in the clamping groove 24.

Therefore, the puncture needle is clamped in the clamping groove and can move back and forth along the clamping groove, and the depth of the puncture needle in a target blood vessel is convenient to adjust.

Preferably, the rotating member is a rotating disc 23, and the engaging groove 24 is convexly disposed on the upper surface of the rotating disc 23.

Preferably, the rotating disc 23 is provided with a handle 25 for rotating the rotating disc 23.

The puncture needle is fixed on the central plane of the length direction of the cylinder wall of the seat cylinder for puncture, so that the puncture efficiency is improved, the puncture positioning is more accurate, and the pain of a patient is reduced.

Detailed Description

Referring to fig. 1 and 2, an auxiliary puncture fixture 2 includes a square base cylinder 21 for receiving an ultrasonic probe 1, a protruding arm 22 disposed on an outer wall of one side of the base cylinder 21 and perpendicular to a cylinder wall of the base cylinder 21, a rotating disc 23 (rotating part) disposed on an end of the protruding arm 22, a handle 25 fixedly connected to an outer side of the rotating disc 23 for driving the rotating disc 23 to rotate, a slot 24 disposed on an upper surface of the rotating disc 23 and protruding from an upper surface of the rotating disc 23, and a puncture needle 3 disposed in the slot 24 and movable along a length direction of the slot 24 so as to adjust a depth of entering a blood vessel.

The puncture needle 3 is arranged on the horizontal central plane of the seat cylinder 21, namely on the horizontal central plane of the ultrasonic probe 1, the ultrasonic probe 1 is directly contacted with the skin to detect the position of a target blood vessel, and the target blood vessel is also arranged on the horizontal central plane of the ultrasonic probe 1, so that the puncture needle 3 and the target blood vessel are arranged on the horizontal central plane of the ultrasonic probe 1, only the handle 25 is used for rotating the rotary disc 23 to adjust the angle of the puncture needle 3 relative to the ultrasonic probe 1, namely the angle of the puncture needle 3 penetrating into the target blood vessel is adjusted, the puncture needle 3 penetrates through the skin to penetrate into the center of the target blood vessel, and then the puncture needle 3 is manually pushed to move along the clamping groove 24, so that the; otherwise, if the puncture needle 3 is not located on the center plane of the hub 21, even if the angle at which the puncture needle 3 penetrates the skin is manually adjusted, the puncture needle 3 that penetrates the blood vessel deviates from the center of the target blood vessel, and there is also a possibility of puncturing the blood vessel, causing pain to the patient.

When the ultrasonic probe 1 is moved to detect a target blood vessel along the skin, the ultrasonic probe 1 cannot move relative to the seat cylinder 21, so that a fastening stud 26 penetrating the wall of the seat cylinder 21 is provided on the opposite side of the projecting arm 22, and a clamping plate 27 fixedly connected to the fastening stud 26 is provided on the inner side of the wall, and when the ultrasonic probe 1 is set in the seat cylinder 21, the fastening stud 26 is manually screwed according to the size of the probe end, and the probe end is clamped in the wall of the seat cylinder 21 by the clamping plate 27.
