Abstract

A surgical cleaning device and method of use having a housing, a drive shaft rotatably mounted, having a rear end and a front end, a brush head positioned at the front end and arranged outside the housing, to which a plurality of elastically deformable bristles are attached, a pump connected with the drive shaft for pumping a rinsing liquid, a gearbox that is connected with the front end of the drive shaft and with a rear end of the tube and which translates the rotational movement of the drive shaft into an oscillating linear movement of the tube and the brush head, wherein the tube is mounted movable in a linear manner; the brush head in the region of the elastically deformable bristles has at least one ejection opening, wherein the tube opens liquid-permeably through the at least one ejection opening in the direction of the elastically deformable bristles.

First claim

The invention claimed is:

1 . A surgical cleaning device comprising:
a housing, a drive shaft, wherein the drive shaft is rotatably mounted in the housing, wherein the drive shaft has a rear end for connection to a drive unit, and wherein the drive shaft has a front end arranged opposite the rear end, a brush head, wherein the brush head has a plurality of elastically deformable bristles attached to the brush head, and wherein the brush head is arranged outside of the housing, a pump for pumping a rinsing liquid, wherein the pump is connected with the drive shaft and to be driven by the drive shaft, a tube, wherein the brush head is arranged at a front end of the tube wherein the tube is arranged linearly movable against the housing and wherein the brush head has at least one ejection opening in the region of the elastically deformable bristles, wherein the tube opens liquid-permeably through at least one ejection opening in the direction of the elastically deformable bristles, a gearbox, wherein the gearbox, is connected with the front end the drive shaft and with a rear end of the tube and wherein the gearbox translates the rotational movement of the drive shaft into an oscillating linear movement of the tube and the brush head, wherein the pump is a self-aspirating pump that is connected directly with the drive shaft wherein the self-aspiring pump is arranged in the housing, and/or the pump is an impeller pump which is arranged on the drive shaft wherein the impeller pump has a rotor with impeller blades wherein the rotor with the impeller blades is connected force and/or form-fitting with the drive shaft.

2 . The surgical cleaning device according to claim 1 , wherein:
the surgical cleaning device comprises a first liquid line wherein the first liquid line is liquid-permeably connected with the rear end of the tube and fixed at the rear end of the tube, and is fixed at one end opposite the rear end of the tube relative to the housing, wherein the first liquid line is a flexible movable hose connected firmly to the rear end of the tube at a first end of the hose.

3 . A surgical cleaning device according to claim 1 , wherein:
the housing has a handle for holding the surgical cleaning device with one hand, and wherein the housing has an opening for the rear end, the drive shaft, and/or the drive shaft is rotatable and driven by a separate drive unit, wherein the separate drive unit for this purpose is connected or connectible, detachably connected or connectible, with the rear end of the drive shaft.

4 . A surgical cleaning device according to claim 1 , wherein:
the surgical cleaning device is made of plastic, wherein the entire surgical cleaning device can be disposed of free of residue by combustion, and/or the surgical cleaning device has a suction device with at least one suction opening in the region of the elastically deformable bristles wherein the suction device has a suction line that is connectible or is connected to a negative pressure source, wherein the suction device is connected or connectible to a separator for separating solid components from the used rinsing liquid and/or the vacuum source has a vacuum pump which is part of the surgical cleaning device, and which can be driven by the drive shaft.

5 . A surgical cleaning device according to claim 1 , wherein:
the surgical cleaning device has a flexible drive shaft extension wherein the flexible drive shaft extension is connected or is connectible, to the rear end of the drive shaft, wherein the flexible drive shaft extension can be connected to an external drive unit, so that the drive shaft with the external drive unit via the flexible drive shaft extension is rotatable against the housing, and/or the brush head is a hollow body and the least one ejection opening connects an interior of the hollow body with the environment in the region of the elastically deformable bristles, wherein the tube opens into the at least one ejection opening via the interior of the hollow body.

6 . A surgical cleaning device according to claim 1 , wherein:
the surgical cleaning device has a resetting element with which the tube is pressed in the direction of the drive shaft, the resetting element being at least one coil spring, wherein particularly at least one spiral spring is arranged around the tube and/or around a shaft for connecting the tube with the gearbox and against the housing, wherein the gearbox has a first plate which is connected to the front end of the drive shaft or is attached to the front end of the drive shaft, wherein the first plate is oblique to the axis of rotation of the drive shaft, and the gearbox has a second plate wherein the second plate is connected with the rear end of the tube or the second plate or is attached to the rear end of the tube, and wherein the second plate is oblique to the longitudinal axis of the tube or oblique to the axis of rotation of the drive shaft and wherein the second plate is pressed against the first plate by the elastic resetting element.

7 . A surgical cleaning device according to claim 1 , wherein:
the gearbox has a plate at the front end of the drive shaft or at the rear end of the tube wherein the plate has a surface inclined against the rotary axis of the drive shaft, or the gearbox has a first plate at the front end of the drive shaft and a second plate at the rear end of the tube wherein the first plate and the second plate each have an inclined surface against the axis of rotation of the drive shaft, wherein the inclined surfaces of the first plate and the second plate are oriented to each other.

8 . A surgical cleaning device according to claim 1 , wherein:
the brush head is connected to the tube via a detachable connection and/or between the brush head and the tube or in the tube, a flexible bendable tube section is arranged, which allows the bending of the brush head against the longitudinal axis of the tube by up to 45°, wherein the flexibly bendable tube section is designed as a sleeve.

9 . A surgical cleaning device according to claim 1 , wherein:
a guide in the housing prevents a rotational movement of the tube against the housing, wherein the housing or a guide of the housing guide the linear movement of the tube, and/or at least one tubular elastic bristle is provided as one of at least one elastic bristles, wherein at least one tubular elastic bristle is hollow inside and liquid-permeably connected with the tube, wherein a free opening of at least one tubular elastic bristles is an ejection opening of the at least one ejection opening.

10 . A surgical cleaning device according to claim 1 , wherein:
at least one cam is attached to the drive shaft and an elastically deformable hose is connected to the rear end of the tube wherein the elastically deformable hose is arranged in the operative region of the cams in such a way that during a complete 360° rotation of the drive shaft, a rinsing liquid flow through the elastically deformable hose around its longitudinal axis is interrupted at least once per revolution of the drive shaft and thereby pulsating rinsing liquid jets from the at least one ejection opening are formed, and/or at least one ejection opening is shaped in such a manner and arranged relative to the elastically deformable bristles in such a way that a stream of rinsing liquid through at least one ejection opening is ejected into the effective range of the linearly oscillating elastically deformable bristles.

11 . A surgical cleaning device comprising:
a housing; a drive shaft, wherein the drive shaft is rotatably mounted in the housing, wherein the drive shaft has a rear end for connection to a drive unit, and wherein the
