Abstract

The invention discloses a laser transmitter on an ultrasonic guidance device. The laser transmitter comprises an ultrasonic probe and a laser transmitter body, the ultrasonic probe comprises a probe body and a handle, the laser transmitter further comprises a fixing ring and a lantern ring, the lantern ring has elasticity and sleeves the probe body, and a rotation shaft is arranged on the side face of the lantern ring; one end of the rotation shaft is connected with the lantern ring, the other end of the rotation shaft is connected with the fixing ring, and the laser transmitter body is inserted in the fixing ring. By using the laser transmitter on the ultrasonic guidance device, an ultrasonic image displayed through a laser can assist doctors in needle insertion, puncture is accurate and simple, the success rate is increased, the efficiency is improved, and a good puncture effect is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laser emitter on an ultrasonic guiding device. Background technique [0002] Ultrasound-guided percutaneous soft tissue biopsy is one of the important diagnostic methods to confirm the nature of soft tissue tumors, thyroid tumors, parotid gland tumors and other superficial tumors. However, the ideal puncture angle by ultrasound positioning is often between 30°-60° from the horizontal line, that is, the operator must estimate the angle well before the needle can be inserted accurately and the puncture is successful, especially when the tumor is small (such as <1cm). Precise positioning is more important. Most ultrasound doctors only estimate the angle of the needle with the naked eye, but there is usually a large deviation. Due to the inaccurate angle of the needle, it is often necessary to repeatedly adjust the angle of the needle before re-inserting the needle, which not...
