{MEDICAL IRRIGIATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical cleaner, and more particularly, to a medical cleaner having a simple and stable conversion unit for converting a rotational motion of a motor into a linear motion to suck and discharge a cleaning liquid.

In the artificial joint surgery, it is necessary to remove a part of the surface of the bone of the joint. In this work, it is necessary to clean the removed bone and blood. Such bones and blood are washed using a washing solution consisting of physiological saline solution. At this time, a washing device for spraying the washing solution is used.

A conventional cleaning device includes a main body having a cleaning liquid spray hole at one end thereof and a space therein, and the main body is made of a flexible material and is easily deformable even by a force exerted by a hand . In order to inject the cleaning solution into the space inside the main body, force the main body to remove the air inside the main body, immerse the cleaning solution spray hole into the cleaning solution reservoir, and suck the cleaning solution by removing the force applied to the main body. After the washing liquid is injected into the internal space of the main body, the washing liquid is injected into the internal space of the main body by the force when the main body of the washing liquid is directed toward the surgical site and the force is applied to the main body. And the surgical site could be washed by the washing solution.

A washing machine has been proposed in which an operation by an electric driving unit is improved (see Korean Patent No. 10-1589282). Referring to FIG. 1, The washing machine (medical cleaning machine) is composed of a housing 2 constituting a body part 1 and various parts arranged inside the housing 2. [ At this time, a washing liquid supply module 10 is mounted in the housing 2. The washing liquid supply module 10 is provided with a stretching member 11 serving as a pump, a driving motor 12, a switch 13 and the like . At this time, the washing liquid supply module 10 serves to supply the washing liquid from the washing liquid reservoir to the washing machine. According to the conventional surgical washing machine, the stretchable member 11 has a bellows shape that can be stretched and contracted, and is formed so as to be stretched and contracted by the operation of the driving motor 12. The driving force transmitting module includes a first gear 21, and a second gear 22 are provided.

Specifically, the first gear 21 serves as a bevel gear to transmit the rotation of the axis of the driving motor 12 to the second gear 22, and the second gear 22 is connected to the cam (not shown) . The cam is connected to one end of the elastic member 11 to transmit the motion of the second gear 22 to the elastic member 11. That is, the rotational force of the driving motor 12 is transmitted to the elastic member 11 by the first gear 21, the second gear 22 and the cam, and the elastic member 11 is stretched or contracted by the transmitted force Is described. Part of the noise and vibration, injection pressure, ie, the method for injecting the cleaning liquid of the existing washing machine, is a method in which the pump is operated to suck the cleaning liquid by injecting the cleaning liquid by changing the linearity through the cam mounted on the gear using the rotation of the gear . However, since this method does not directly connect the motor and the pump and has a large number of parts, the construction is complicated and the manufacturing cost is increased. In addition, since the driving force is converted through various steps and the force is transmitted, There is a shortage. Further, when the gears are not properly engaged by applying the bevel gear, unnecessary noise may be generated, which may interfere with communication at the time of operation. In addition, when the gears are meshed with an excessive force so that the gears operate correctly, the absorption power of the cleaning liquid may be lowered due to frictional force between the gears, etc. In addition, a large amount of blood or contaminants , The scrubber for spraying the scrubbing liquid has to be a small size that can be easily manipulated by hand, and therefore, there is a burden to accommodate a large amount of the scrubbing liquid sucked in.

Thus, the scrubber needs to be composed of a small device and easy to operate, and it must be possible to spray an effective cleaning liquid.

In the following description of the embodiments of the present invention, descriptions of techniques which are well known in the technical field of the present invention and are not directly related to the present invention will be omitted. This is for the sake of clarity of the present invention without omitting the unnecessary explanation.

For the same reason, some of the components in the drawings are exaggerated, omitted, or schematically illustrated. Also, the size of each component does not entirely reflect the actual size. In the drawings, the same or corresponding components are denoted by the same reference numerals.

FIG. 4 is a conceptual view illustrating an electric motor unit, a cleaning liquid pumping unit, and a motion converting unit of a medical cleaner provided with a cleaning liquid supply device according to an embodiment of the present invention. FIG. 6 is a conceptual diagram illustrating a motor shaft fixing part and a rib projection according to an embodiment of the present invention. Referring to FIG.

Hereinafter, a medical cleaner provided with a cleaning liquid supply device according to an embodiment of the present invention will be described.

Referring to FIG. 4, an electric motor unit 100, a cleaning liquid pumping unit 200, and a motion converting unit 300 are shown. Although not shown, the above configuration is located inside the casing portion of the medical cleaner and functions to suck the cleaning liquid. The cleaning liquid according to the embodiment of the present invention performs cleaning by sucking the outside cleaning liquid and injecting the cleaning liquid into the affected area or the like. Since the cleaning liquid required for cleaning is continuously supplied, the cleaning liquid pumping unit 200 of the electric driving type, So as to spray the cleaning liquid.

As such, the pumped liquid pumping portion 200 provides a force to draw in the liquid stored in the pumped liquid reservoir existing outside the medical washer. The cleaning liquid pumping unit 200 is formed with a pump having a corrugated structure for sucking the cleaning liquid. This corrugated structure can most effectively provide the function of the pump when the reciprocating motion is performed in a direction perpendicular to the corrugation of the pump.

On the other hand, electric motors are the simplest and most effective means of generating driving force. However, since the electric motor generates a force for rotating the drive shaft 110, it is necessary to convert the rotational force into a reciprocating motion. Referring to the drawing, it can be seen that the motion converting unit 300 is provided between the electric motor unit 100 and the pump of the cleaning liquid pumping unit 200, so that the rotational force of the electric motor is transmitted to the pump. In this case, the motion converting unit 300 is configured to be reciprocated by being positioned on the straight line with the pumps of the electric motor unit 100 and the cleaning liquid pumping unit 200, and is largely driven by the interaction of the two parts The structure is very simple.

More specifically, the motor shaft fixing part 310 is coupled with the driving shaft 110 of the electric motor part 100 so as to rotate together with the rotation of the driving shaft 110. The reciprocating unit 320 reciprocates in the axial direction while being inserted into the motor shaft fixing unit 310.

This reciprocating motion may be performed by a rib projection 311 formed in the motor shaft fixing portion 310 and a spiral projection 321 formed in the reciprocating portion 320.

Referring to FIG. 6, it can be seen that a pair of ribs 311a and 311b are formed on the inner surface of the motor shaft fixing part 310 into which the reciprocating part 320 is inserted.

More specifically, the reciprocating unit 320 can be divided into a center shaft 321, a spiral projection 321, and a loader 322. [

The center shaft 321 is formed to be insertable into a portion where the drive shaft 110 of the motor is inserted. The spiral protrusion 321 is formed at a portion of the motor drive shaft 110 excluding the center shaft 321 inserted into the insertion portion and is formed with an outer diameter adjacent to the inner diameter of the motor shaft fixing portion 310. Accordingly, the outer surface of the spiral protrusion 321 may slide in the motor shaft fixing portion 310. [ The helical projections 321 may be formed in a continuous curved surface.

The spiral protrusion 321 may be formed of a first portion 321a and a second portion 321b. At this time, the first portion 321a is gradually formed in a gentle slope from the protruding side to the other side The second portion 321b may be formed on one side and the other side corresponding to the first portion 321a and the other side of the first portion 321a may be formed in contact with one side of the second portion 321b have. That is, the rib projections 311a and 311b are moved along the inclined surfaces formed in the first and second portions 321a and 321b so that the helical projections 321 are reciprocated within the motional drive shaft fixing portion 310, You will be able to exercise. At this time, the central axis 321 formed with the rib projections 311a and 311b is provided with an elastic member such as a spring, so that the reciprocating motion can be effectively performed.

The loader 322 may be connected to the pump shaft of the cleaning liquid pumping unit 200 and may be connected to the other side of the center shaft 321 inserted into the motor shaft fixing unit 310 and sliding.

When the motor shaft fixing portion 310 rotates through this configuration, the inner rib projections 311a and 311b move along the inclined surface of the spiral protrusion 321, and the rib projection 311a , 311b may occur, and the pump may be operated through the axial movement of the loader 322 connected thereto.

The motion converting unit 300 includes two parts, that is, the rotation of the motor shaft fixing unit 310 and the reciprocating unit 320, so that the rotational force can be effectively converted into the reciprocating force. There is a concern that this may be a major cause of failure of the motion converting unit 300. [ Accordingly, in the inner surface of the casing of the medical cleaner according to the embodiment of the present invention, the motor shaft fixing part 310 is supported while preventing the motor shaft fixing part 310 from moving when the motor shaft fixing part 310 rotates At least one guide portion may be formed.

For this, at least one ring-shaped guide rail may be formed on the outer peripheral surface of the motor shaft fixing part 310, and the guide part may be formed with a guide groove so that the guide rail can be inserted and guided.

The rib protrusions 311a and 311b may be formed to reach the open end of the motor shaft fixing portion 310 except for the inner space where the spiral protrusion 321 can move up and down. Through this structure, the reciprocating motion of the reciprocating unit 320 can be more reliably guided. Although not shown, a disk-shaped guide member may be further provided on the outer circumferential surface of the loader 322 located on the other side of the center shaft 321. Sliding grooves may be formed on both side surfaces of the guide member so that sliding can be performed through the rib projections 311a and 311b formed to the ends of the mocker shaft fixing part 310. [ As described above, the guide member is located adjacent to the inner diameter of the motor shaft fixing portion 310 and may be provided to mitigate the vibration of the motion converting portion 300 together with the guide rail by guiding the reciprocating motion.

Although the present invention has been described with reference to preferred embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is not intended to limit the scope. It is to be understood by those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
