Description

A kind of laser therapy hand tool of adjustable spot size

Technical field

The utility model is related to optical therapeutic technical fields, and in particular to a kind of laser therapy hand of adjustable spot size Tool.

Background technology

With the development of medical technology, laser technology is also increasingly extensive in the application of medical field, has also promoted medical sharp The continuous development of light device.The application of medical laser equipment has the following advantages：Act only on pathological tissues and to periphery health Tissue damage is small, and precision is high, treatment cycle is short, few intercurrent disease, does not have electro photoluminescence, postoperative easy recovery etc..

The basic principle of laser therapy is to utilize laser irradiation skin, acupuncture point or affected part, to achieve the purpose that treat disease. And laser therapy hand tool is a crucial component of laser therapy, the output of laser will be transmitted to lesion group by treatment handpiece It knits to achieve the purpose that treatment, the core technology of laser therapy is the regulation and control of laser power density, and power density and laser Facula area has substantial connection, can be to the health tissues of perilesional if making hot spot be more than lesions position in adjustment process It makes a big impact, if making hot spot be less than lesions position in adjustment process, and entire lesion cannot disposably be gone completely It removes, therefore the spot size of laser and energy density are required for being controlled very precisely, to realize the treatment to different lesions.

Operator is in the course of surgery, it will usually complete to control using different spot sizes during seance It treats, therefore, treatment handpiece should have the function of adjusting spot size, and spot size, energy density are periodically adjusted in energy one It can change correspondingly.There are following two structures for the laser therapy hand lamps structure of the prior art：

The first structure is can not to continuously adjust the hand tool of hot spot, and concrete structure is：Dismountable treatment head is placed in hand Have ontology below, inside lens are installed.Due to exporting the treatment head interior len of different treatment size hot spots in therapeutic process Position is different, therefore in a therapeutic process, and operator needs, according to different lesions Treatment need, frequently to replace different Treatment head.It is primarily present following two disadvantages：1, such frequent hand tool for becoming dismounting treatment can increase the work of operating personnel Intensity causes patient's stand-by period long, and consequence is to be unable to reach best therapeutic effect, frequently replaces and be easy to cause operation Error, other injuries are brought to patient；2, keeping backup treatment head can increase the workload that daily cleaning is safeguarded and taken care of, and cause The waste of cost.

Second of structure is the hand tool of continuously adjustable hot spot, and concrete structure is：There are one being set in hand tool body interior Potentiometer and lens subassembly.When operation, the spot size scale that ontology is marked with is had according to hand and determines required treatment spot size, Rotation hand tool ontology drives its interior lens position change, while driving the sliding tap at potentiometer regulation resistance end, to change Become the output voltage of hand tool, and the voltage signal is sent to microcontroller, microcontroller is known according to the voltage signal received Other spot signal, and judge that spot size is eventually displayed on the interface of host.It has the disadvantage that：1, same in potentiometer Electrical parameter discreteness is larger at mechanical location, needs to carry out parameter compensation；2, since the sliding tap of potentiometer is with hot spot tune It saves and moves, prolonged use can cause hand tool ontology inner potential device abrasion, reduce hand and have service life.

Utility model content
