HIFU-used arc array probe assembling structure and replacing method thereof

Abstract

The invention discloses an HIFU-used arc array probe assembling structure and a replacing method thereof. An arc array probe is embedded in the closed front-end of a sealing circular pipe, and the cable connector of the tail part of the arc array probe penetrates out of the sealing circular pipe. The cable connector is connected with an external cable through an electrical connector assembly, andan electrical shielding cover sleeving outside the electrical connector assembly is connected on the tail end of the sealing circular pipe through a fastening screw. The sealing circular pipe is coaxially sleeved in the locating sleeve of the center of a clamping bowl, and the front end of the sealing circular pipe and the locating sleeve are fixed through expanding screws arranged along the circumference. The structure uses the mechanical clamping mode, the structure is simple, the cost is low and sealing is reliable, and center locating is performed by using the coaxial cylindrical sleeve mode and thus locating is fast and accurate; the arc array probe can be conveniently replaced from the front end without detaching the sleeve so as to meet the requirement of onsite replacing; and the stainless steel shell and overall silicone rubber pouring are used so as to effectively prolong the service life.

Description

technical field [0001] The invention relates to an assembly structure of an arc array probe for HIFU and a replacement method thereof, belonging to the technical field of ultrasonic treatment equipment. Background technique [0002] The treatment source of High Intensity Focused Ultrasound (HIFU) tumor therapy system is ultrasound. Similar to the principle that solar cookers focus sunlight to generate huge energy at the focus, this technology focuses low-energy ultrasound in vitro on the target area in the body, and produces biological effects such as transient high temperature (above 60°C), cavitation, and mechanical action in the tumor. Kill tumor cells in the target area. [0003] In order to reduce the occupation of the effective radiation area, the focused ultrasound treatment system uses a phased array as a real-time monitoring B-ultrasound probe. Long; the repair process required the removal of many other mechanical parts from the rear, and the removal and installat...

Problems solved by technology

Generally, the puncture positioning of the conventional probe cannot directly ensure the coincidence of the puncture guide line and the puncture needle, and each operation needs to be calibrated in the bucket in advance
