Description

Technical Field

[0001] The invention relates to a roller module for a medical robot, equipment for the medical robot and a medical robot. Background Art

[0002] In medical surgery, there is a method of inserting a surgical tool (for example, a balloon catheter, etc.) into the body to treat a disease related to blood vessels (for example, cardiovascular coronary artery and peripheral artery interventional surgery).

[0003] During such a surgery, X-rays are required to determine the position of a balloon catheter or the like inserted into the body. In this case, the medical staff performing the surgery are at risk of being exposed to X-ray radiation.

[0004] In order to solve this problem, research on medical robots for transferring catheters is underway. Medical personnel can control the medical robots via wireless signals in a space separate from the surgical site, thereby protecting the medical personnel from the effects of X-ray radiation.

[0005] However, ordinary medical robots have the problem of being contaminated by the patient's body substances due to repeated use. Although the contaminated substances are removed by washing the medical robot, infection caused by the contaminated substances may occur if it is not completely washed.

[0055] The advantages, features and methods for achieving the advantages, features and methods of the present invention can be clearly understood by referring to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and can be implemented in various different forms. The present embodiments are provided only to complete the disclosure of the present invention and to fully inform the ordinary technicians in the technical field to which the present invention belongs. The present invention is only defined by the scope of the claims.

[0056] The terms used in this specification are for the purpose of illustrating embodiments and are not intended to limit the present invention. In this specification, unless otherwise mentioned, the singular includes the plural. "Comprises" and / or "comprising" used in the specification do not exclude the existence or addition of one or more other constituent elements other than the mentioned constituent elements. Throughout the entire specification, the same reference numerals refer to the same constituent element, and "and / or" includes each of the mentioned constituent elements and all combinations of more than one. Although "first", "second" and the like are used to describe a variety of constituent elements, these constituent elements are obviously not limited by these terms. These terms are only used to distinguish one constituent element from other constituent elements. Therefore, the first constituent element mentioned below can obviously be a second constituent element within the technical idea of ​​the present invention.

[0057] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification may be used with the meanings commonly understood by ordinary technicians in the technical field to which the present invention belongs. In addition, for terms defined in commonly used dictionaries, unless otherwise clearly and specifically defined, they should not be idealized or over-interpreted.

[0058] As spatially relative terms, "below", "beneath", "lower", "above", "above", "upper", etc. can be used to easily describe the correlation between one constituent element and another constituent element as shown in the figure. Spatially relative terms should be understood as terms that include different directions of constituent elements when used or operated in addition to the directions shown in the drawings. For example, in the case of flipping the constituent elements shown in the drawings, a constituent element described as being "below" or "beneath" another constituent element can be located "above" another constituent element. Therefore, "below" as an exemplary term can include both the directions of below and above. Constituent elements can also be configured in other directions, and accordingly, spatially relative terms can be interpreted according to their configuration direction.

[0059] Hereinafter, the "vertical direction" may refer to the up-down direction in the figure. Furthermore, the "vertical direction" may be parallel to the rotation axis of the "roller drive". That is, the rotation axis of the roller unit may be parallel to the "vertical direction".

[0060] Hereinafter, the medical robot 1 of the present invention will be described with reference to the accompanying drawings. The medical robot 1 of the present invention can transfer a guide catheter 61, a guide wire 62, and a balloon catheter 63 for surgery. In this case, the surgery can be a cardiovascular coronary artery and peripheral artery interventional surgery. The interventional surgery introduces the balloon catheter 63 into the cardiovascular system to artificially widen the blocked blood vessels, thereby treating heart disease.

[0061] The guide catheter 61 may be a hollow tube that accommodates the guide wire 62 and the balloon catheter 63. The guide wire 62 is a wire having a length, and may perform the function of supporting and pulling the balloon catheter 63.

[0062] like Figure 1 As shown, the medical robot 1 of the present invention may include a first driving device 10 , a second driving device 20 , a third driving device 30 , a first connector 40 and a support plate 50 .

[0063] The first driving device 10, the second driving device 20 and the third driving device 30 can transfer the guide catheter 61, the guide wire 62 and the balloon catheter 63. In this case, the first driving device 10 can hold the guide catheter 61, the second driving device 20 can hold the guide wire 62, and the third driving device 30 can hold the balloon catheter 63.

[0064] The first driving device 10 , the second driving device 20 , and the third driving device 30 can perform “rolling drive”, “clamping drive”, and “vertical drive” in order to transfer the guide catheter 61 , the guide wire 62 , and the balloon catheter 63 .

[0065] Reference Figure 2 and Figure 3 The “rolling drive” may be a drive in which the roller units of the first driving device 10 , the second driving device 20 , and the third driving device 30 rotate to move the guide catheter 61 , the guide wire 62 , and the balloon catheter 63 in the length direction.

[0066] And, refer to Figure 2 and Figure 3 The “clamping drive” may be a drive in which the roller units of the first drive device 10 , the second drive device 20 , and the third drive device 30 facing each other move closer or farther away to control the clamping degree of the guide catheter 61 , the guide wire 62 , and the balloon catheter 63 .

[0067] In addition, refer to Figure 5 and Figure 6"Vertical drive" is the drive in which the rollers of the first drive device 10, the second drive device 20 and the third drive device 30 move in the vertical direction and rotate the guide catheter 61, the guide wire 62 and the balloon catheter 63 with bent ends, thereby determining the transfer direction of the guide catheter 61, the guide wire 62 and the balloon catheter 63.

[0068] The medical robot 1 of the present invention is characterized in that the guide catheter 61 , the guide wire 62 , and the balloon catheter 63 are accurately transferred by the above-mentioned three types of driving.

[0069] Furthermore, the roller unit of the medical robot 1 of the present invention is manufactured in a box form so as to be replaceable, and thus surgery can be performed hygienically.

[0070] Furthermore, the first driving device 10 , the second driving device 20 , and the third driving device 30 of the medical robot 1 of the present invention may have two arrangement forms.

[0071] First, refer to Figure 2 The first arrangement form is described as follows: the moving direction of the first driving device 10 and the moving direction of the second driving device 20 may be located on the same straight line, and the moving direction of the first driving device 10 and the moving direction of the third driving device 30 may be arranged obliquely.

[0072] In this case, the first connector 40 may be used. The first connector 40 may be disposed between the first driving device 10 and the second driving device 20 while supporting the guide catheter 61, the guide wire 62, and the balloon catheter 63.

[0073] Further, the first connector 40 may be movable along the transfer direction of the first driving device 10 and the second driving device 20 in order to stably support the guide catheter 61 , the guide wire 62 , and the balloon catheter 63 .

[0074] To this end, the first connector 40 may include: a first connector body 41 that fixes the guide catheter 61 , the guide wire 62 , and the balloon catheter 63 ; and a first connector support 42 that extends downward from the first connector body 41 .

[0075] Furthermore, a support plate guide rail 51 for guiding the movement of the first connector support platform 42 of the first connector 40 may be formed on the support plate 50 .

[0076] Below, refer to Figure 3The second arrangement form is described as follows: the moving direction of the first drive device 10 and the moving direction of the second drive device 20 can be arranged obliquely, the moving direction of the first drive device 10 and the moving direction of the third drive device 30 can be arranged obliquely, and the moving direction of the second drive device 20 and the moving direction of the third drive device 30 can be arranged obliquely. Further, the moving directions of the first drive device 10, the second drive device 20, and the third drive device 30 can intersect at an intersection.

[0077] In this case, the second connector 40 - 1 may be used. The second connector 40 - 1 is a “Y-shaped connector” that may form an intersection of the transfer directions of the first drive device 10 , the second drive device 20 , and the third drive device 30 .

[0078] The second connector 40 - 1 may include: a second connector body 41 - 1 ; and a second connector support platform 42 - 1 extending downward from the second connector body 41 - 1 to support the second connector body 41 - 1 .

[0079] In addition, the second connector body 41-1 may include: a first receiving portion 41-2 for receiving the guide catheter 61; a second receiving portion 41-3 for receiving the guide wire 62; and a third receiving portion 41-4 for receiving the balloon catheter 63. In this case, the first receiving portion 41-2 of the second connector 40-1 may be connected to both the second receiving portion 41-3 of the second connector 40-1 and the third receiving portion 41-4 of the second connector 40-1.

[0080] Hereinafter, the first driving device 10 of the medical robot 1 of the present invention will be described with reference to the accompanying drawings. In addition, the second driving device 20 and the third driving device 30 can be analogically applied to the first driving device 10. That is, the first driving device 10, the second driving device 20 and the third driving device 30 can have substantially the same technical concept.

[0081] The first driving device 10 may include: a first roller module 100 , a second roller module 200 and a base module 300 .

[0082] The roller units 110 of the first roller module 100 and 210 of the second roller module 200 may be arranged opposite to each other, and their rotation axes may be parallel to each other and their rotation directions may be opposite to each other.

[0083] The “rolling drive” of the first driving device 10 may be achieved by the roller unit 110 of the first roller module 100 and the roller unit 210 of the second roller module 200 rotating in opposite directions to each other.

[0084] The “clamping drive” of the first driving device 10 can be realized by the roller unit 110 of the first roller module 100 and the roller unit 210 of the second roller module 200 approaching each other or moving away from each other.

[0085] The “vertical driving” of the first driving device 10 may be achieved by moving the roller unit 110 of the first roller module 100 and the roller unit 210 of the second roller module 200 in opposite directions in the vertical direction.

[0086] Furthermore, the roller unit 110 of the first roller module 100 and the roller unit 210 of the second roller module 200 may be replaced in a box form.

[0087] First, the first roller module 100 is described. In addition, the second roller module 200 can be analogically applied to the first roller module 100. That is, the first roller module 100 and the second roller module 200 can have substantially the same technical concept.

[0088] As in Figure 8 As shown, the first roller module 100 may include a roller unit 110 and a driving unit 120 .

[0089] The roller unit 110 may include: one or more rollers 111 ; and one or more shafts 114 which may be independently combined with the one or more rollers 111 of the roller unit 110 and rotated by the driving unit 120 .

[0090] like Fig. 9 As shown, one or more holes or grooves 111 - 1 for independently arranging at least a portion of one or more shafts 114 of the roller unit 110 may be formed on the one or more rollers 111 of the roller unit 110 .

[0091] The results, such as Fig.13 As shown, one or more rollers 111 of the roller unit 110 can be installed or separated by sliding in a vertical direction from one or more shafts 114 of the roller unit 110 (replaceable box form). In this case, the housing 112 of the roller unit 110 can also be installed or separated together with the one or more rollers 111 of the roller unit 110. To this end, the first hook 112-1 of the housing 112 can be locked or unlocked. In addition, the one or more rollers 111 are rotatably coupled to the housing 112, and one or more holes or grooves corresponding to the holes or grooves 111-1 of the roller 111 can be formed in the housing 112. The hole or groove of the housing 112 can be formed on the lower surface of the housing 112 and can extend to the upper surface of the housing 112. According to this structure, the one or more rollers 111 of the roller unit 110 can be installed and separated together in a state of being accommodated in the housing 112 of the roller unit 110.

[0092] Further, in order to simplify installation and separation, one or more holes or grooves 111-1 of one or more rollers 111 of the roller unit 110 may extend in the vertical direction. Also, the horizontal cross-section of the one or more holes or grooves 111-1 of the one or more rollers 111 of the roller unit 110 and the horizontal cross-section of the one or more shafts 114 of the roller unit 110 may have corresponding shapes to each other.

[0093] Furthermore, in order to securely install and separate, the horizontal cross-sectional shape of the hole or groove 111-1 of one or more rollers 111 of the roller unit 110 and the horizontal cross-sectional shape of one or more axes 114 of the roller unit 110 can be a shape extending in the first direction and the second direction on the horizontal plane and vertically intersecting at the center point.

[0094] The roller unit 110 can be rotated (roller drive) with the “vertical direction” as an axis by the driving unit 120 .

[0095] Reference Fig.10 To this end, the driving unit 120 may include a first driving motor 122. In addition, the rotation axis of the first driving motor 122 of the driving unit 120 and the rotation axes of the one or more shafts 114 of the roller unit 110 may be perpendicular to each other.

[0096] This can be achieved by means of bevel gears. The drive unit 120 can also include a first drive shaft 123. The spur gear 122-1 of the first drive motor 122 of the drive unit 120 can be meshed with the spur gear 123-1 of the first drive shaft 123 of the drive unit 120. The one or more bevel gears 114-1 of one or more shafts 114 of the roller unit 110 can be independently meshed with one or more bevel gears 123-2 of the first drive shaft 123 of the drive unit 120.

[0097] That is, the driving force of the first driving motor 122 can be transmitted to the first driving shaft 123 through the spur gear 122-1 of the first driving motor 122 and the spur gear 123-1 of the first driving shaft 123. Further, the driving force of the first driving shaft 123 can be transmitted to the one or more shafts 114 of the roller unit 110 through the one or more bevel gears 123-2 of the first driving shaft 123 and the bevel gears 114-1 of the one or more shafts 114 of the roller unit 110.

[0098] The roller unit 110 of the first roller module 100 and the second roller unit 210 of the second roller module 200 can be moved by the base module 300 to move closer or farther apart (clamping drive).

[0099] Reference Fig.11To this end, the basic module 300 may include: a first basic body 310; a first nut 340, arranged on the first basic body 310 of the basic module 300 and combined with the first roller module 100; a second nut 350, arranged on the first basic body 310 of the basic module 300 and combined with the second roller module 200; a lead screw 330, engaged with the first nut 340 of the basic module 300 and the second nut 350 of the basic module 300; and a first driving motor 320, which rotates the lead screw 330 of the basic module 300.
