Novel high-frequency glass cutting head

Abstract

The invention provides a novel high-frequency glass cutting head. The novel high-frequency glass cutting head comprises an inserting structure, wherein the inserting structure comprises a main body part and a cutting part, the main body part and the cutting part are both single-layer pipeline-shaped structure, the inner portion of the main body part is communicated with the inner portion of the cutting part, and the cutting part is arranged at the front end of the main body part; the surface of the novel high-frequency glass cutting head is provided with a suction hole, and the suction hole iscommunicated with an inner cavity of the inserting structure; the port surface of the suction hole is provided with cutting wires, the cutting wires cross above the suction hole, the fracture portionof the cutting part on the edge of one side of the suction hole is provided with a zigzag notch, the zigzag notch comprises teeth and tooth grooves which are arranged at intervals, and the cutting wires above the zigzag notch are all located right above the tooth grooves; a high-frequency vibration source drives the inserting structure to perform high-frequency vibration on the outer portion, thecutting wires vibrate along with the inserting structure and the amplitude is increased to perform lateral shearing on human tissue in the zigzag notch, when an external negative pressure device works, an inner cavity of the inserting structure forms a negative pressure environment, the human tissue is cut up by the high-frequency vibrating cutting wires, and the cut up human tissue flows to thezigzag notch under the action of surface tension and negative pressure suction and is sucked into the suction hole. The novel high-frequency glass cutting head has the advantages that the suction effect is improved, the operative time is shortened, and complications are reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a novel high-frequency glass cutting head. Background technique [0002] At present, in the medical industry, the vitreous body used for eye tissue cutting is generally completed by using a vitreous cutter to cut and absorb the vitreous body. Since the vitreous body in the eye is viscous, in order to achieve this viscous Shaped vitreous, mechanized membrane and blood clots are gradually crushed and removed. Existing vitreous cutters are designed with complex structures, generally double-layered tubes with a high degree of cooperation, and the inner tube reciprocates at high speed during work. The vitreous cutter with a large structure is not only bulky, but also inconvenient to operate, with low cutting and suction efficiency. The effect of cutting and absorbing membranes, lenses and blood clots is not good. At the same time, because the liquid flow is intermittent, it will c...

[0002] At present, in the medical industry, the vitreous body used for eye tissue cutting is generally completed by using a vitreous cutter to cut and absorb the vitreous body. Since the vitreous body in the eye is viscous, in order to achieve this viscous Shaped vitreous, mechanized membrane and blood clots are gradually crushed and removed. Existing vitreous cutters are designed with complex structures, generally double-layered tubes with a high degree of cooperation, and the inner tube reciprocates at high speed during work. The vitreous cutter with a large structure is not only bulky, but also inconvenient to operate, with low cutting and suction efficiency. The effect of cutting and absorbing membranes, lenses and blood clots is not good

At the same time, because the liquid flow is intermittent, it will cause the tissues in the eye to shake greatly, which may easily lead to retinal tear or accidental injury.
