Focused ultrasound treatment head adaptive contact control system and method

Abstract

The invention discloses a focused ultrasound treatment head adaptive contact control system and method. A plurality of pressure sensor are utilized to collect contact data between a treatment head and a human body, thereby overcoming the case that the contact degree of the treatment head is judged according to doctor's experience in the prior art, and realizing objective and quantitative detection of the contact conditions of the treatment head; and through water sac subregion independent arrangement and intelligent control of water level of each region, the high-intensity focused ultrasound treatment head capable of changing the shape of a water sac flexibly is provided, thereby facilitating the treatment head to be fit to the skin part of the human body better, preventing scalding accidents due to poor contact of the treatment head in the prior art, and ensuring the treatment effect. The focused ultrasound treatment head adaptive contact control system and method can be widely applied to various high-intensity focused ultrasound treatment systems.

Description

technical field [0001] The present invention relates to the field of medical devices, in particular to a control system and method for a high-intensity ultrasonic focusing therapy head. Background technique [0002] High-intensity ultrasound focused therapy is a medical treatment technology that has developed rapidly in recent years. This technology can perform ablation of deep-level lesion tissues in the body without incision, especially in tumor treatment. It has unique advantages. Due to the characteristics of ultrasonic transmission, it cannot be transmitted in the air. It is required that the entire acoustic channel during the treatment process must be well-coupled and without air gaps. Therefore, the closeness of the contact between the treatment head and the human body is particularly important. If the contact is not good, It is very likely that there will be medical accidents such as skin burns caused by excessive local energy caused by local gaps. However, under the...

Problems solved by technology

Due to the characteristics of ultrasonic transmission, it cannot be transmitted in the air. It is required that the entire acoustic channel during the treatment process must be well-coupled and without air gaps. Therefore, the closeness of the contact between the treatment head and the human body is particularly important. If the contact is not good, It is very likely that there will be medical accidents such as skin burns caused by excessive local energy caused by local gaps. However, under the current technical conditions, the water bag of the treatment head is fixed, and a large part of the contact between the treatment head and the human body during the treatment depends on the doctor. According to the experience, it is estimated whether the degree of contact is good, which will also bring errors to a certain extent, and there are also certain safety risks.
