Abstract

A fat sucking apparatus including a tip having a tubular body which defines therein a suction passage and which has at least one suction opening at the front lower end of the tubular body, a hand piece to which the tip is detachably connected and which has therein a suction passage which is connected to the suction passage of the tip, said hand piece being provided with an ultrasonic oscillation generating portion which transmits the ultrasonic oscillation to the tip, an outer tube in which the tip is slidably inserted and held and which is provided with at least one suction opening, an ultrasonic oscillator which generates and transmits an electric energy to the ultrasonic oscillation generating portion of the hand piece to supply it with the ultrasonic oscillation, a collector which is connected to the suction passage of the hand piece through a suction pipe to receive the fat, and a vacuum pump which is connected to the collector to suck the fat into the collector.

Claims

1. A fat sucking apparatus comprising:

a tip having a tubular body which defines therein a suction passage and which has at least one suction opening at the front lower end of the tubular body;

a hand piece to which the tip is detachably connected and which has therein a suction passage which is connected to the suction passage of the tip, said hand piece being provided with an ultrasonic oscillation generating portion which transmits the ultrasonic oscillation to the tip;

an outer tube in which the tip is slidably inserted and held, and which is provided with a plurality of suction openings;

means for moving said tip along the length of said outer tube when said apparatus is in use such that said tip suction portion can be disposed proximate to each of said plurality of suction openings of said outer tube;

an ultrasonic oscillator which generates and transmits an electric energy to the ultrasonic oscillation generating portion of the hand piece to supply it with the ultrasonic oscillation;

a collector which is connected to the suction passage of the hand piece through a suction pipe to receive the fat; and

a vacuum pump which is connected to the collector to suck the fat into the collector.

2. A fat sucking apparatus according to claim 1, wherein said tip includes a tubular body which defines therein a suction passage and a grip to be held by an operator.

3. A fat sucking apparatus according to claim 2, wherein said outer tube has a rounded front end.

4. A fat sucking apparatus according to claim 3, further comprising a cooler for cooling the tip.

5. A fat sucking apparatus according to claim 1, wherein said outer tube is made of plastic having a high heat resistance.

6. A fat sucking apparatus according to claim 1, wherein said at least one suction opening of said tip comprises a plurality of suction openings.

7. A fat sucking apparatus according to claim 6, wherein said plurality of suction openings are disposed adjacent one another along the length of said tip at said front lower end of said tubular body, said plurality of tip suction openings defining a suction portion of said tip.

8. A fat sucking apparatus according to claim 7, wherein each of said plurality of suction openings of said outer tube has a length substantially corresponding to a length of said suction portion of said tip.

9. A fat sucking apparatus according to claim 8, wherein said plurality of suction openings of said tip comprises two adjacent tip suction openings within said suction portion of said tip.

10. A fat sucking tool comprising:

a cannula comprising a tip having a tubular body which defines therein a suction passage and which has at least one suction opening at the front lower end of the tubular body, and a hand piece to which the tip is detachably connected and which has therein a suction passage which is connected to the suction passage of the tip, said hand piece being provided with an ultrasonic oscillation generating portion which transmits the ultrasonic oscillation to the tip;

an outer tube in which the tip is slidably inserted and held, and which is provided with a plurality of suction openings;

and further comprising means for moving said tip along the length of said outer tube when said tool is in use such that said tip suction portion can be disposed proximate to each of said plurality of suction openings of said outer tube.

11. A fat sucking tool according to claim 10, wherein said at least one suction opening of said tip comprises a plurality of suction openings.

12. A fat sucking tool according to claim 11, wherein said plurality of suction openings are disposed adjacent one another along the length of said tip at said front lower end of said tubular body, said plurality of tip suction openings defining a suction portion of said tip.

13. A fat sucking tool according to claim 12, wherein each of said plurality of suction openings of said outer tube has a length substantially corresponding to a length of said suction portion of said tip.

14. A fat sucking tool according to claim 13, wherein said plurality of suction openings of said tip comprises two adjacent tip suction openings within said suction portion of said tip.

15. A fat sucking tool comprising:

a cannula comprising a tip having a tubular body which defines therein a suction passage and which has at least one suction opening at the front lower end of the tubular body, and a hand piece to which the tip is detachably connected and which has therein a suction passage which is connected to the suction passage of the tip, said hand piece being provided with an ultrasonic oscillation generating portion which transmits the ultrasonic oscillation to the tip;

an outer tube in which the tip is slidably inserted and held, and which is provided with a plurality of suction opening; and

means for slidably moving said tip within and relative to said outer tube when said tool is in use so that said at least one suction opening of the tip is positionable proximate to each of said plurality of outer tube suction openings.

16. A fat sucking tool according to claim 15, wherein said at least one suction opening of said tip defines a suction portion of said tip, said suction portion of said tip having a length corresponding to a length of each of said plurality of outer tube suction openings.

17. A fat sucking tool according to claim 16, wherein said suction portion of said tip comprises a plurality of suction openings.
