Embodiment 1

[0039] This embodiment provides a photodynamic diagnosis and treatment instrument for port wine stains, which is used to treat port wine stains. It can detect the lesions in the skin tissue before or after treatment. The diagnosis and treatment instrument specifically includes: photodynamic therapy device and OCT scanning device, the OCT scanning device and the photodynamic therapy device share an industrial control motherboard and an operating system, and the OCT scanning device is provided with a data interface for connecting to a computer, through which the OCT scanning device can be connected to an external independent computer. The OCT scanning device can detect the microscopic treatment effect of the skin section before, after or during the treatment. In practice, the diagnosis and treatment instrument is as follows: figure 1 As shown, it includes: host 1, OCT detection head 2, OCT scanning device, display and control panel 3, handle support device 4, optical fiber fixin...

Embodiment 2

[0053] Such as Figure 9 As shown, this embodiment provides a photodynamic diagnosis and treatment instrument for port wine stains, which is used to treat port wine stains. On the basis of the first embodiment above, a handle support device 4 is provided, and the treatment handle 7 is fixed by the handle support device 4. The handle supporting device 4 is formed by connecting a multi-section support arm and a universal rotating head, each supporting arm is flexibly connected, one end of the multi-section supporting arm is fixed, and the other end is provided with a universal rotating head, and the universal rotating head is provided with There is a bracket for placing the treatment handle. The specific structure of the handle support device 4 in practice is as follows: Figure 9As shown, joint one 92, joint two 98, and joint three 96 are connected by rotating shaft 91, knob 93, pin shaft, washer, connecting rod 97 and front end joint 99 to form a multi-section support arm, an...

Abstract

The invention discloses a port wine stains photodynamic diagnosis and treatment instrument, which includes a photodynamic cure device and an OCT scan device. One industrial control mainboard and one operation system are shared for the OCT scan device and the photodynamic cure device, the OCT scan device is equipped with a data interface for connecting an external computer. By cooperation of the OCT scan device and the photodynamic treatment device, the diagnosis and cure instrument detects microscopic section of processed pathological change skin tissue and confirms treatment effect on microscopic view, wherein imaging scan resolution can be in micron-level and exceeds traditional detection way far and away. The diagnosis and treatment instrument can real-time display section tissue structure images of detected position by using the OCT scan device, realize image processing functions to make the images more clear and provide scientific evidence for pathological change diagnosis and estimation of therapeutic effect. The diagnosis and cure instrument resolves problem in prior art that estimations of skin pathological change part by visual observation and experience and to therapy results are inaccurate.

Description

technical field [0001] The invention relates to a medical device used in skin tissue treatment, in particular to a semiconductor laser power diagnosis and treatment instrument used in photodynamic therapy of port wine stains and OCT skin tissue detection. Background technique [0002] Port wine stain, also known as port wine stain, commonly known as "red birthmark", is a congenital capillary malformation. Most patients are found to have light red or red patches on the skin after birth, and can also be manifested as large-area (diameter 2-10cm) bright red patches with smooth surface and clear boundaries; damage can occur in the body Any part of the body, but the face, neck and scalp are more prone to hair. Except for abnormal color, there are no other special symptoms. A small number of patients are also accompanied by deformities of other organs and mental retardation. Port wine stains generally do not disappear on their own, and will increase proportionally with the growt...
