Abstract

A collagen gathering apparatus including a fat tissue crusher having a cannula which is inserted in a fat tissue to crush the fat tissue by an ultrasonic oscillation, a sucker having a suction pipe and a vacuum pump for sucking the fat tissue crushed by the crusher, and a collector which is connected to the suction pipe of the sucker and which has a filter for separating the fat tissue into a collagen and a liquid component.

Claims

1. A collagen gathering apparatus, comprising:

a fat tissue crusher including a cannula, an outer tube containing said cannula, and an ultrasonic oscillator means for oscillating said cannula, said outer tube having a plurality of suction openings and a suction passage therein in communication with said plurality of suction openings, wherein said cannula can be inserted in fat tissue to crush the fat tissue by ultrasonic oscillation caused by said oscillator means;

a suction means having a suction pipe in communication with said suction passage and a vacuum pump in communication with said suction pipe, for providing suction to said suction pipe to enable it to extract the fat tissue crushed by the crusher; and

a collagen collector which is connected between said suction pipe of said suction means and said vacuum pump, said collagen collector having a filter with means for separating the fat tissue extracted by said suction pipe into a collagen component and a liquid component.

2. A collagen gathering apparatus according to claim 1, wherein said cannula comprises a tip portion having a tubular body which defines therein a portion of said suction passage and which has at least one of said plurality of suction openings at the front end of said tubular body, and wherein said cannula further comprises a hand piece to which said tip portion is detachably connected and which has therein a further portion of said suction passage which is connected to said portion of said suction passage in said tip portion of said cannula.

3. A collagen gathering apparatus according to claim 2, wherein said ultrasonic oscillator means is connected to said hand piece, wherein said ultrasonic oscillator means further comprises an ultrasonic oscillation generating portion connected to said hand piece which transmits the ultrasonic oscillation to said tip portion of said cannula.

4. A collagen gathering apparatus according to claim 3, wherein said ultrasonic oscillator means further comprises an ultrasonic oscillation source connected to said ultrasonic oscillation generating portion.

5. A collagen gathering apparatus according to claim 2, wherein said tip portion of said cannula can be slidably inserted and held in said outer tube.

6. A collagen gathering apparatus according to claim 5, wherein said outer tube is spaced apart from said tip portion of said cannula.

7. A collagen gathering apparatus according to claim 4, wherein said suction pipe comprises a front suction pipe which is connected for communication with said suction passage of said tip portion and of said hand piece, and a rear suction pipe which is connected for communication with said front suction pipe and said vacuum pump.

8. A collagen gathering apparatus according to claim 7, wherein said collector is located between said front suction pipe and said rear suction pipe.

9. A collagen gathering apparatus according to claim 8, wherein said collector further comprises a reservoir, for receiving said liquid component, so that said liquid component separated from the fat tissue can be collected in said reservoir.

10. A collagen gathering apparatus according to claim 9, wherein said filter collects thereon the collagen separated from the fat tissue.

11. A collagen gathering apparatus according to claim 2, further comprising a cooler means connected to said cannula, for cooling said tip portion of said cannula.

12. A collagen gathering apparatus comprising:

an ultrasonic oscillation crushing means, which can be inserted in a fat tissue of a human body, for crushing the fat tissue with an ultrasonic oscillation, said ultrasonic oscillation crushing means including a cannula, having a tip portion an outer tube containing said cannula, and an ultrasonic oscillator means for oscillating said cannula, said outer tube having a plurality of suction openings and a suction passage therein in communication with said plurality of suction openings, wherein said cannula can be inserted in fat tissue to crush the fat tissue by ultrasonic oscillation caused by said oscillator means;

a suction means for extracting the fat tissue crushed by said ultrasonic oscillation crushing means;

a passage means for conveying the extracted fat tissue therethrough;

a collecting means for collecting the fat tissue conveyed through the passage means; and

,

a separating means for separating a collagen from the collected fat tissue, wherein said tip portion of said cannula can be slidably inserted and held in said outer tube.

13. A collagen gathering apparatus according to claim 12, further comprising an ultrasonic oscillation generating means for generating the ultrasonic oscillation.

14. A collagen gathering apparatus according to claim 13, further comprising a cooling means for cooling the apparatus.
