Abstract

A tissue removal pen includes a pen body having a working end and a handle portion, and an abrasion unit, which is mounted on the pen body, including an abrasion head extended outwardly from the working end of the pen body for removing cells from a treating skin surface of a user. A collecting unit includes a collecting conduit, which is mounted on the pen body, having a discharging end and an intake end extended toward the working end, and a collecting head replaceably mounted to the intake end of the collecting conduit and extended from the working end of the pen body to a position that adjacent to the abrasion head of the abrasion unit. A vacuuming source is connected to the discharging end of the collecting conduit to provide a reduced pressure within the collecting head for collecting cells removed from the treating skin surface.

Claims

1. A tissue removal pen, comprising:

a pen body having a working end and a handle portion;

an abrasion unit comprising an abrasion head replaceably mounted to said working end of said pen body, wherein said abrasion head has top coupling end, a bottom scrubbing end, and an abrasion body solidly extended from said coupling end to said scrubbing end, said abrasion head further having a periphery bottom edge surrounding at said scrubbing end and a scrubbing surface defined within said periphery bottom edge for removing cells from a treating skin surface of a user;

a collecting unit comprising a collecting conduit, which is extended along said pen body, having an intake end extended toward said working end, and a collecting head, having a bottom sucking opening, replaceably mounted to said intake end of said collecting conduit wherein said collecting head is extended from said working end of said pen body to a position that said sucking opening is adjacent to said scrubbing surface of said abrasion head of said abrasion unit; and

a vacuuming source coupled with said discharging end of said collecting conduit to provide a reduced pressure within said collecting head for collecting cells removed from the treating skin surface through said sucking opening.

2. A tissue removal pen, as recited in claim 1, wherein said abrasion unit further comprises an abrasive socket firmly affixed to said working end of said pen body and wherein said abrasion head comprises a receiving plug provided at said coupling end of said abrasion body and detachably inserted into said abrasive socket so as to replaceably mount said abrasion head on said pen body.

3. A tissue removal pen, as recited in claim 1, wherein said collecting head has an adapter portion detachably mounted to said intake end of said collecting conduit and a cup portion having a bell- shaped to form said sucking opening having an enlarged circular sucking area, wherein said scrubbing surface of said abrasion head is positioned adjacent to said sucking opening.

4. A tissue removal pen, as recited in claim 2, wherein said collecting head has an adapter portion detachably mounted to said intake end of said collecting conduit and a cup portion having a bell- shaped to form said sucking opening having an enlarged circular sucking area, wherein said scrubbing surface of said abrasion head is positioned adjacent to said sucking opening.

5. A tissue removal pen, as recited in claim 1, wherein said collecting head has an adapter portion detachably mounted to said intake end of said collecting conduit and a cup portion shaped to form said sucking opening having an U-shaped structure so as to define a receiving space, wherein said scrubbing surface of said abrasion head is positioned within receiving space.

6. A tissue removal pen, as recited in claim 2, wherein said collecting head has an adapter portion detachably mounted to said intake end of said collecting conduit and a cup portion shaped to form said sucking opening having an U-shaped structure so as to define a receiving space, wherein said scrubbing surface of said abrasion head is positioned within said receiving space.

7. A tissue removal pen, as recited in claim 1, wherein said collecting head has an adapter portion detachably mounted to said intake end of said collecting conduit and a cup portion shaped to form said sucking opening having a ring-shaped structure to define a receiving space therewith, wherein said scrubbing surface of said abrasion head is coaxially positioned within said receiving space.

8. A tissue removal pen, as recited in claim 2, wherein said collecting head has an adapter portion detachably mounted to said intake end of said collecting conduit and a cup portion shaped to form said sucking opening having a ring-shaped structure to define a receiving space therewith, wherein said scrubbing surface of said abrasion head is coaxially positioned within said receiving space.

9. A tissue removal pen, as recited in claim 4, wherein said vacuuming source comprises a vacuum pump device and an extension tube connected said vacuum pump device to a discharging end of said collecting conduit in such a manner that said vacuum pump device is arranged to provide said reduced pressure through said sucking opening of said collecting head for collecting said cells from said treating skin surface.

10. A tissue removal pen, as recited in claim 6, wherein said vacuuming source comprises a vacuum pump device and an extension tube connected said vacuum pump device to a discharging end of said collecting conduit in such a manner that said vacuum pump device is arranged to provide said reduced pressure through said sucking opening of said collecting head for collecting said cells from said treating skin surface.

11. A tissue removal pen, as recited in claim 8, wherein said vacuuming source comprises a vacuum pump device and an extension tube connected said vacuum pump device to a discharging end of said collecting conduit in such a manner that said vacuum pump device is arranged to provide said reduced pressure through said sucking opening of said collecting head for collecting said cells from said treating skin surface.

12. A tissue removal pen, as recited in claim 4, wherein said vacuuming source further comprises a control switch comprising a pusher arm transversely mounted on said pen body in a slidably movable manner for transversely biasing against said collecting conduit and a switch body extended from said pusher arm for driving said pusher to a position that when said pusher arm is moved toward said collecting conduit to bias against said collecting conduit, a pressure through said sucking opening is reduced, and when said pusher arm is moved away from said collecting conduit, said pressure through said sucking opening is increased.

13. A tissue removal pen, as recited in claim 6, wherein said vacuuming source further comprises a control switch comprising a pusher arm transversely mounted on said pen body in a slidably movable manner for transversely biasing against said collecting conduit and a switch body extended from said pusher arm for driving said pusher to a position that when said pusher arm is moved toward said collecting conduit to bias against said collecting conduit, a pressure through said sucking opening is reduced, and when said pusher arm is moved away from said collecting conduit, said pressure through said sucking opening is increased.

14. A tissue removal pen, as recited in claim 8, wherein said vacuuming source further comprises a control switch comprising a pusher arm transversely mounted on said pen body in a slidably movable manner for transversely biasing against said collecting conduit and a switch body extended from said pusher arm for driving said pusher to a position that when said pusher arm is moved toward said collecting conduit to bias against said collecting conduit, a pressure through said sucking opening is reduced, and when said pusher arm is moved away from said collecting conduit, said pressure through said sucking opening is increased.

15. A tissue removal pen, as recited in claim 9, further comprising a motor assembly comprising a motor securely supported in said pen body and electrically connected to a power source via a conductive wire and a motor shaft operatively extended from said motor to said abrasion head, so as to provide an abrasion movement of said scrubbing surface of said abrasion head.
