Laser guider for ultrasonic puncture and guiding device

Abstract

The invention discloses a laser guider for ultrasonic puncture and a guiding device. The laser guider comprises a shell, a fixation clamp, a laser module, a battery, and a control switch. A laser emitting opening is formed in the front end of the shell. The fixation clamp is arranged on the bottom surface of the shell and is used for fixing the shell on an ultrasonic probe; and an included angle is formed between the axial direction of the laser emitting opening and the axial direction of the fixation clamp. The laser module is arranged in the shell and is used for generating laser and emitting the laser from the laser emitting opening. The battery is electrically connected with the laser module and used for providing power for the laser module. The control switch is exposed on the surfaceof the shell and is electrically connected with the battery and is used for controlling on-off of a power supply of the laser module. According to the invention, the doctor can visually and rapidly perform positioning during intraperitoneal puncture without experience estimation; the puncture position can be accurately found with repeated trial and error; the puncture positioning precision is improved; and the damage to other tissues is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guider and guide device for puncture after intraperitoneal ultrasonic positioning. Background technique [0002] Ultrasonic interventional diagnosis and treatment technology is a technology developed on the basis of ultrasound imaging to meet the needs of clinical diagnosis and treatment. First, ultrasound is used for positioning, and then the diseased tissue in the patient's body can be easily extracted or injected into the patient's body through a puncture needle or a treatment needle. Drugs or treatments are injected into a target site (such as tumors, nerves, blood vessels, etc.) in the patient's body. [0003] In actual operation, intraperitoneal puncture is generally performed by hand under the guidance of ultrasound. This method needs to judge the puncture position based on the doctor's experience and estimation, and the positioning accuracy is low. Multiple punc...

Problems solved by technology

[0003] In actual operation, intraperitoneal puncture is generally performed by hand under the guidance of ultrasound. This method needs to judge the puncture position based on the doctor's experience and estimation, and the positioning accuracy is low. Multiple punctures often occur to determine the position, which is not only time-consuming Strenuous and easy to damage other tissues
