Description

Caster connection structure of medical robots

[0001] The present invention relates to a structure for connecting a caster of a medical robot, and more particularly, by combining a buffer member with the connecting structure of the medical robot to form a structure capable of dispersing the load of the medical robot, not only can vibration and noise caused by the load of the medical robot be significantly reduced, but also caster failure and damage can be prevented in advance, and the hygiene and cleanliness of the caster connecting structure can be further improved.

[0002]

[0003] Medical robots are generally used in medical institutions such as hospitals, and are mainly classified and developed into surgical and surgical simulator robots, rehabilitation and nursing robots, etc., and are equipment that can perform various medical functions and assistive tasks in hospitals.

[0004] As demand for healthcare technologies and other technologies increases due to the aging population, research and development related to medical robots are continuously being conducted, and these medical robots are already playing an important role in the medical field.

[0005] Most of the above-mentioned medical robots are equipped with casters at the bottom for moving the equipment. The casters of the medical robots are manufactured in various sizes and materials depending on the characteristics of the equipment, so that the equipment can be moved smoothly.

[0006] In addition, casters for medical robots are designed and manufactured to reduce noise and corrosion, in addition to providing high durability for moving equipment, and to be suitable for the cleanliness and hygiene required in medical institutions.

[0007] As a prior art document related to a caster equipped in equipment such as a medical robot, there is a patent application entitled “Caster unit and medical device including the same” in Korean Patent Publication No. 10-2592908.

[0008] The above-mentioned conventional invention provides a caster unit and a medical device including the same, which includes a shock absorbing part having a relatively simple structure and good shock absorption properties, and which can prevent damage due to external force generated during distribution or movement of the medical device through good shock absorption, and can suppress or minimize transmission of uncomfortable vibrations to the user.

[0009] And, as another prior art document, the title of the invention of Korean Patent Publication No. 10-1100545, “Caster Device,” provides a caster device that is mounted on a moving body and can continuously switch the operating mode of the caster.

[0010] However, the casters installed in the conventional medical robots or equipment mentioned above lack a structure and function to appropriately distribute and alleviate the load of the medical robot or equipment, and thus, during long-term use, problems such as increased vibration and noise, caster failure, deformation, damage, and breakage occur.

[0011] In addition, in medical institutions such as hospitals where cleanliness and hygiene are important, there is a need for research and development of caster connection structures that not only have a buffering function but also have disinfection and chemical resistance, as the structures that perform caster buffering may corrode and become contaminated with various pathogens.

[0012]

[0013] In order to solve the above-mentioned problem, the present invention provides a caster connection structure of a medical robot, which is formed by combining a flexible material buffer member with an expanded contact area to a caster connection structure of a medical robot, thereby distributing the load of the medical robot and minimizing vibration and noise of the equipment, and thereby preventing damage, deformation, breakage, and failure of the caster.

[0014] In addition, the present invention provides a caster connection structure of a medical robot that can be formed so that a separate cover can be fastened to the caster connection structure of the medical robot, thereby preventing corrosion of the caster connection structure and contamination by various foreign substances and bacteria, thereby enabling the caster connection structure to be maintained hygienically and cleanly.

[0015]

[0016] The present invention comprises a coupling member having a coupling recess formed so that the upper surface is fixed to the lower part of the main body of a medical robot and the upper side of a buffer member is recessed into the lower surface, and a coupling member groove formed so that the upper part of a cover is assembled;

[0017] An assembly hole having an assembly hole recess formed so that a caster is assembled and fastened at the bottom, an assembly hole having an assembly hole recess formed so that the lower side of a buffer member is recessed into the upper surface, and an assembly hole having an assembly hole recess formed so that the lower part of the cover is assembled;

[0018] A buffer member having an upper protrusion formed to be inserted into the joint inlet, and a lower protrusion formed to be inserted into the assembly inlet;

[0019] A cover formed by a set of flexible resin materials, each facing the left and right in a 'ㄷ' shape on a plane, and covering the outside of a buffer member fastened to a joint and assembly member;

[0020] It is characterized by being composed of.

[0021]

[0022] As described above, the present invention is a beneficial invention that forms a flexible material cushioning member with an expanded contact area to be combined with the caster connection structure of a medical robot, thereby distributing the load of the medical robot and minimizing vibration and noise of the equipment, and thereby preventing damage, deformation, breakage, and malfunction of the caster in advance, and by forming a separate cover to be attached to the caster connection structure of the medical robot, corrosion of the caster connection structure and contamination by various foreign substances and bacteria can be prevented, thereby enabling the caster connection structure to be maintained hygienically and cleanly.

[0050]

[0051] The unexplained symbol R is the medical robot body, and C is the caster.

[0052]

[0053] Hereinafter, the configuration and operational effects according to the embodiments of the present invention will be described in detail with reference to the attached drawings.

[0054] As illustrated in FIGS. 1 to 5, the caster connection structure of the medical robot of the present invention is such that the upper protrusion (310) of the buffer member (300) is inserted and connected to the coupling hole inlet (110) of the coupling hole (100) fixed to the lower part of the medical robot body (R).

[0055] Then, the lower protrusion (320) of the buffer member (300) is inserted and fastened into the assembly hole inlet (210) of the assembly hole (200) coupled to the upper part of the caster (C), and each corner portion of the coupling hole (100) and the assembly hole (200) is coupled with a separate bolt, etc., so that the coupling hole (100) and the assembly hole (200), and the buffer member (300) therebetween, are firmly assembled and coupled to each other.

[0056] At this time, the load or vibration generated when the medical robot body (R) is in operation or when moving using the caster (C) can be mitigated and reduced by the flexible material buffer member (300), and the load, vibration, noise, etc. transmitted from the upper protrusion (310) and the lower protrusion (320) that have a polygonal shape on the plane and a polygonal protrusion and depression on the side are repeated to maximize the contact area can be dispersed and mitigated and reduced.

[0057] In addition, by assembling the upper part of the cover (400) into the joining groove (120) and the lower part of the cover (400) into the assembly groove (220), and by assembling them together through the separately provided joining means such as holes and protrusions of the covers (400) on both sides, the outside of the buffer member (300) between the joining groove (100) and the assembly groove (200) can be covered and protected and exposure can be blocked, so that the phenomenon of various pathogens and molds growing in the gaps of the assembly area, or the phenomenon of foreign substances and contaminants accumulating in the gaps caused by disinfection or cleaning, can be effectively prevented.

[0058] Moreover, the cover (400) can also be expanded and contracted along with the movement of the medical robot body (R) and the movement of the caster (C) due to the curved portion (410) in the central portion of the cover (400), and the wave-shaped curved portion (410) has no dense gaps due to its shape, thereby preventing contaminants from entering or pathogens from inhabiting, and can provide a caster connection structure of the medical robot that is always hygienic and clean.
