Multifunctional medical laser treatment device

Abstract

The invention discloses a multifunctional medical laser treatment device which comprises a first laser module body and a second laser module body. A first 45-degree complete reflecting mirror, a first partially reflecting mirror, a 1.32mu m acoustic optical modulator, a first optical shutter and a first total transmitting complete reflecting mirror are sequentially arranged on one side of the first laser module body along the optical axis direction of the first laser module body. A fourth total transmitting complete reflecting mirror, a third optical shutter and a second 45-degree total transmitting complete reflecting mirror are sequentially arranged on one side of the second laser module body along the optical axis direction of the second laser module body. A second partially reflecting mirror is arranged on the other side of the second laser module body along the optical axis direction of the second laser module body. The multifunctional medical laser treatment device has the following advantages of meeting requirements for laser with different wavelengths to maximum limit in a whole minimally invasive interventional treatment process, meeting various intracavitary treatment needs, performing coagulation hemostasis and washing the surface of a wound while performing vaporization incision on focus tissue, achieving functions of vaporization, incision and coagulation hemostasis on a platform, and being small in incision surface damages, minimally invasive and safe.

Description

technical field [0001] The invention relates to laser treatment technology, in particular to a medical multifunctional laser treatment device. Background technique [0002] Laser energy is highly concentrated in time, space, and spectrum, making it widely used in many fields. Among them, medicine is the earliest, most extensive and most active subject that applies laser technology. Countries around the world have developed many kinds of laser medical equipment for different therapeutic purposes and used them in clinical treatment. [0003] At present, it has become a development trend in the field of international surgery to achieve the goal of curing diseases with minimal trauma. The traditional surgical model is constantly being eliminated by the new minimally invasive interventional surgery. Minimally invasive interventional therapy has become one of the main methods of clinical treatment in modern hospitals. . Modern minimally invasive surgery requires advanced physic...

Problems solved by technology

[0009] Although laser devices with different laser wavelengths for tissue vaporization, cutting, and hemostasis have appeared, since these laser devices with different wavelengths are independent, it is difficult to integrate them into the same device at the same time. The main technical difficulties Reasons: 1. The technology of the laser cooling system is insufficient. The laser output of three wavelengths requires three sets of cooling equipment to work at the same time, and the cooling power is very high. room requirements

2. It is difficult to synthesize the optical path. The lasers of three wavelengths emitted by three laser modules are coupled into a surgical optical fiber surgical tool at the same time. The structure is very complicated, and the requirements for the coating of optical lenses are very high. The current coating technology cannot meet its requirements

[0010] If laser devices with different laser wavelengths such as vaporization, cutting, and hemostasis are used independently in the same operation, the actual surgical operation cannot meet the special needs of each surgical process, and the optimal therapeutic effect cannot be obtained. For example, if you want to stop bleeding at the same time after using the vaporization device to vaporize the tissue, you need to take out the surgical knife that transmits the vaporization laser that enters the human tissue, remove the vaporization device, and then move the hemostatic device to the patient , re-insert the transmission hemostatic laser surgical knife into the human surgical site; this is not only cumbersome to operate, but also takes a long time in the middle, and conventional hemostatic equipment is needed to stop the bleeding first, and the real hemostasis effect cannot be achieved.

In the same way: when an operation requires cutting and hemostasis at the same time, there will be the same problem
