Embodiment Construction

[0028] It can be seen from the background art that the cutter head of the tissue morcellator provided by the prior art is likely to cause secondary injury to the patient.

[0029] Combining with a kind of laser surgery process of enucleation of benign prostatic hyperplasia, we will analyze the reasons why it is easy to cause secondary harm to patients:

[0030] In laser surgery for enucleation of benign prostatic hyperplasia, first use the laser operating handle with an endoscope to cut off the prostatic hyperplasia tissue with laser; then rely on external negative pressure to expel the excised tissue from the body.

[0031] Specifically, the principle of expelling tissue from the body includes: the tissue morcellator consists of a rotating hollow inner cutter and a fixed outer sheath. When entering the cutting environment, the hollow part of the inner cutter is connected to negative pressure, and the cutter mouth is brought close to the tissue to be pulverized; after the nega...

Abstract

The invention provides a tissue destructor tool bit and a laser treatment device. The tissue destructor tool bit comprises a fixed seat, an outer sheath having a tubular structure, an inner cutter and a metal wire passage, wherein one end of the outer sheath is connected with the fixed seat, and an edge is formed in the tube wall of the other end of the outer sheath; the inner cutter is arranged in the outer sheath in a rotary sleeving manner; the first end of the inner cutter is far from the fixed seat, and is partially exposed from the edge; the metal wire passage is arranged in parallel to the outer sheath, and is fixedly connected with the tube wall of the outer sheath; and a memory metal wire is arranged in the meal wire passage, and can be stretched and bent in the metal wire passage and forms a protection space above the edge. According to the invention, the application safety of the tissue destructor tool bit can be improved, and secondary injury can be avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cutter head of a tissue morcellator and a laser treatment device. Background technique [0002] Laser is one of the great inventions of mankind in the 20th century, and it is widely used in many fields. The clinical value of low-intensity laser irradiation therapy has been affirmed at home and abroad. Mainly used in the treatment of brain diseases, cardiovascular diseases, diabetes, malignant tumors, leukemia, psychiatric diseases, psoriasis, rhinitis and other diseases. According to the discovery of health medicine, low-intensity laser has a good curative effect in the early prevention of cardiovascular and cerebrovascular diseases and the recovery period after the onset, and has a certain effect on health and inhibition of human aging. In addition, laser technology is also widely used in biochemical testing, blood analysis, etc., and high-power lasers can also be used in su...
