The side 341 of the housing 340 is connected to the bottom 342 of the housing 340, and the bottom 342 of the housing 340 is the surface facing the human body during the operation. The link 33 is a substantially rigid link 33 that is directly mounted to the power mechanism 20 when the operating arm 30 is installed, eliminating the need to bend the link 33. In other embodiments, link 33 may also be a flexible link 33.

The operating arms 30 are tangent to the housing 340, so that the connecting rods 33 of the operating arms 30 can extend into the body through one incision on the human body, the distance between the driving mechanisms 34 of the operating arms 30 can be reduced, the operating arms 30 are further more compact, and the volume of the area where the operating arms 30 are installed on the power mechanism 20 is reduced. Further, since the link 33 is a rigid link 33, the operation is more stable.

In the embodiment shown in fig. 4 and 5, the housing 340 has a first side surface 341A and a second side surface 341B adjacent to each other, and both are used for abutting against the first side surface 341A or the second side surface 341B of the adjacent operating arm 30, so that the plurality of operating arms 30 are distributed around a central axis; or the first side 341A and the second side 341B are configured to be disposed adjacent to and spaced apart from the first side 341A or the second side 341B of the adjacent operating arm 30, so that the plurality of operating arms 30 are distributed around a central axis, for example, the first side 341A of one of the two adjacent housings 340 is disposed opposite to the first side 341A or the second side 341B of the other housing 340, and a gap is formed between the opposite surfaces. The first side 341A and the second side 341B form an acute angle. In other embodiments, the first and second side surfaces 341A and 341B may form a right angle or an obtuse angle.

Further, the edge of the first side surface 341A extends to the edge of the second side surface 341B, so that the two side surfaces 341 are connected, and the connection region is a curved surface. Wherein the connecting rod 33 is tangent to the curved surface, in one embodiment, the radius of curvature of the curved surface is substantially the same as the radius of the connecting rod 33. In other embodiments, the curvature radii of the curved surfaces may also be different. Alternatively, in other embodiments, as shown in fig. 6-11, the connecting rod may not be disposed adjacent to the plurality of sides.

In other embodiments, the housing may be other shapes. In the embodiment shown in fig. 6 and 7, the housing is rectangular. In the embodiment shown in fig. 8 to 11, the housing 340 has a first body 343, the first body 343 has a mounting surface 344 for connecting the power mechanism 20, and a second body 345 extends on the mounting surface 344, so that a free end of the second body 345 protrudes out of the mounting surface 344, and forms a notch 36 with the first body 343 for receiving the power mechanism 20, wherein the free end extends out of an end of the first body 343 which is not connected thereto. In fig. 8 to 10, the second body extends along one edge of the mounting surface to form the housing into an L-shape. In fig. 11, the second body extends from a middle region of the mounting surface such that the housing forms a T-shape with two notches 36.

In each embodiment, the mode of the embodiment shown in fig. 4 and 5 can be adopted for the area where the link is provided in the housing. For example, the second body has a first side face and a second side face adjacent to each other, and both are used for abutting against the first side face or the second side face of the adjacent operation arm, or used for being arranged close to and spaced from the first side face or the second side face of the adjacent operation arm, so that the plurality of operation arms are distributed around a central shaft.

As shown in fig. 4 to 11, the surface of the housing for connecting the power mechanism and the surface provided with the connecting rod may have various positional relationships.

In the embodiment shown in fig. 4, the surface of the housing 340 for connecting the power mechanism is opposite to the surface where the connecting rod 33 is disposed. Specifically, the connecting rod 33 is disposed on the bottom 342 of the housing 340 and adjacent to an edge region of the bottom 342, and a surface of the housing 340 opposite to the bottom 342 is used for connecting the power mechanism.

In the embodiment shown in fig. 6, the surface of the housing 340 for connecting the power mechanism 20 and the surface where the connecting rod 33 is disposed are the same surface, specifically, the bottom 342 of the housing 340 has a connecting plate 35 for connecting the power mechanism 20, and the connecting rod 33 is disposed on the bottom 342 of the housing 340.

In the embodiment shown in fig. 7, the surface of the housing 340 for connecting the power mechanism 20 may be disposed adjacent to the surface where the connecting rod 33 is disposed, that is, one side 341 of the housing 340 for connecting the power mechanism is disposed, and the connecting plate 35 is disposed thereon.

In the embodiment shown in fig. 8 to 11, the link is provided on the second body, and in fig. 8, 9 and 11, the mounting surface 344 is parallel to the link 33, and in fig. 10, the mounting surface 344 is perpendicular to the link 33. In fig. 8, 10, and 11, the notch 36 is located in the direction of the side surface of the second body, and in fig. 9, the notch 6 is located in the direction of the surface of the second body opposite to the bottom surface. Specifically, the connecting rod 33 is disposed on the area of the second body 345 near the free end, for example, on the bottom surface of the second body, which is the surface facing the human body during operation, and is tangent to the side surface of the second body in the extending direction thereof, which is the surface adjacent to the bottom surface. The mounting surface 344 is provided with a connection pad 35 for connection to the power structure 20.

In addition, the connecting rod 33 may be disposed on the side surfaces 341 of the housing 340, and in this case, a surface of the housing 340 for connecting with the power mechanism may be on one of the side surfaces 341, the bottom surface 342, or a surface opposite to the bottom surface 342. The link 33 may also be located adjacent to the side area, not tangential to the side.

In the above embodiment, the link 33 is a straight rod, and the link 33 is rotatably disposed on the housing 340 of the driving mechanism 34, and the driving mechanism 34 drives the link 33 to rotate along the axis thereof. In other embodiments, the connecting rod 33 may be a non-straight rod structure. Alternatively, the link 33 may be fixedly provided to the housing 340.

As shown in fig. 12, in an embodiment, the connecting rod 33 includes a first connecting rod 331 and a second connecting rod 332 connected in sequence, wherein the first connecting rod 331 is disposed on the housing 340 and is fixedly connected to the second connecting rod 332, and the first connecting rod 331 and the second connecting rod 332 form an included angle, which is a non-straight angle. In this embodiment, the second connecting rod 332 is tangent to the side 341 of the housing 340, and the connecting rod 33 is fixedly disposed on the housing 340. At this time, the distal end instrument 31 connected to the link 33 can be relatively rotated, thereby securing the degree of freedom of the operation arm 30. In other embodiments, the second link 33 may be non-tangent to the housing 340, so long as the second links 33 of the plurality of operation arms are ensured to enter the body through one incision.

The first link 33 may also be rotatably disposed on the housing 340. For example, the first link 33 is a flexible rod, a flexible tube, or the first link 33 is connected with the second link 33 through a flexible joint assembly, so that the position between the first link 33 and the second link 33 is adjustable; the second link 33 is inserted through the poking card or the sleeve to limit the position of the second link relative to the human body, so that the first link 33 drives the second link 33 to rotate around the fixed rotation axis, that is, the rotation axis of the second link 33 will not change with the bending of the first link 33. For another example, the second link 33 is fixed in position relative to the first link 33, and at this time, the first link 33 is connected to the second link 33 through a transmission mechanism, so that when the first link 33 rotates, the second link 33 is driven to rotate around the fixed rotation axis. When the first link 33 is rotatably disposed on the housing 340, the first link 33 may be located at a middle region of the surface of the housing 340.

It should be noted that, when the first connecting rod 33 is a flexible rod or a flexible tube, or the first connecting rod 33 is connected to the second connecting rod 33 through a flexible joint assembly, the first connecting rod 33 may also be fixedly connected to the housing 340, and at this time, the distal end instrument 31 connected to the connecting rod 33 may be relatively rotated.

As shown in fig. 13, in an embodiment, the link 33 includes a first link 331 and a second link 332, and the connecting assembly 32 includes a first connecting assembly 321 and a second connecting assembly 322. The first link 331 is disposed on the driving mechanism 34 and is connected to the second link 332 through the first connecting component 321 in a swinging manner, the second link 332 is used for connecting the distal end instrument 31 or the second connecting component 322, wherein when the second link 332 is connected to the second connecting component 322, the distal end instrument 31 is connected to the distal end of the second connecting component 322. The first connecting component 321 is located outside the body and the second connecting component 322 is located inside the body during the operation. Note that, in the present embodiment, the second link 332 is tangent to the side 341 of the housing 340. In other embodiments, the second connecting rod 332 may not be tangent to the housing 340, but may have other positions.

The operation arm 30 drives the connecting assembly 32 through the driving mechanism 34, so that the second connecting rod 332 swings relative to the first connecting rod 331, the positions of the second connecting rod 332 and the terminal instrument 31 connected with the second connecting rod 332 are further adjusted, the space between the driving mechanism 34 of the operation arm 30 and a human body is fully utilized, and the flexibility of the operation arm 30 is improved.

In one embodiment, the number of the first links 331 is plural, the plural first links 331 are sequentially connected via the first connecting element 321 in a swinging manner, the first link 331 located at the proximal end is connected to the driving mechanism 34, and the first link 331 located at the distal end is connected to the second link 332 via the first connecting element 321. This further increases the flexibility of the operating arm 30.

Fig. 14 and 15 are schematic diagrams illustrating an exploded view of a partial structure of a slave operation device and a structure of an embodiment of a power mechanism 20 according to the present invention.

The power mechanism 20 includes a body 210 and a power unit 220. Wherein, the side 211 of the body 210 is provided with an installation groove 213, the installation groove 213 penetrates through the bottom 212 of the body 210, so that the operation arm 30 is translated from the side 211 to the installation groove 213, and the distal end thereof is located outside the installation groove 213, i.e. the distal end instrument 31 of the operation arm 30 is substantially located outside the installation groove 213 during the translation installation, and the distal end instrument 31 does not need to penetrate through the installation groove 213 to extend out of the installation groove 213; the power unit 220 is disposed on the body 210, and is used for connecting the driving mechanism 34 of the operation arm 30 and providing power for the operation arm 30 to make the operation arm 30 perform corresponding operations, such as changing the position or posture of the distal end instrument 31. The bottom surface 212 of the body 210 refers to the surface facing the patient during operation, and the side surface 211 is the surface adjacent to the bottom surface 212.

When the operation arm 30 is installed, the operation arm 30 is firstly translated into the installation groove 213 from the opening of the installation groove 213 located on the side surface 211 of the body 210, and at this time, since the installation groove 213 penetrates through the bottom surface 212 of the body 210, the operation arm 30 is not blocked by the bottom surface 212 in the process of translating to the installation groove 213. After translating to the mounting groove 213, the operation arm 30 is connected to the power unit 220. The slave operation device with the power mechanism 20 makes the operation arm 30 to be installed more simply and quickly.

In this embodiment, there is one mounting groove 213, and there are a plurality of power units 220, and each power unit 220 is connected to its corresponding operating arm 30. The plurality of operation arms 30 connected to the power unit 220 are inserted into the mounting grooves 213, so that the plurality of operation arms 30 can be inserted into the body through one slit.

In other embodiments, the power mechanism 20 may have only one power unit 220. Alternatively, at least two of the plurality of operation arms 30 may be inserted into the mounting groove 213. For example, part of the operation arm 30 is disposed in the body 210 and penetrates the installation groove 213, so that the end of the operation arm extends out of the body 210, and part of the operation arm 30 is disposed outside the body 210 without penetrating the installation groove 213.

In other embodiments, there may be more than one mounting groove 213. For example, there are two mounting grooves 213, wherein at least one mounting groove 213 accommodates two operation arms 30, and the remaining operation arms 30 are accommodated in the other mounting groove 213. At this time, the mounting grooves may be formed on the same side surface or different side surfaces of the body, for example, two side surfaces of the body opposite to each other. A plurality of the operation arms 30 are inserted into the body through two cutouts, each corresponding to one of the installation grooves 213, so that the operation arms 30 inserted from the installation grooves 213 are inserted into the corresponding cutouts.

It should be noted that, when there are a plurality of mounting grooves, at least two mounting grooves may also correspond to one notch, that is, the operating arms extending from the plurality of mounting grooves corresponding to one notch all extend into the body through one notch. Alternatively, a plurality of operation arms 30 extending from the same mounting groove 213 may extend into the body from a plurality of cutouts.

The body 210 further defines a receiving groove 214 for receiving the power portion 220. When the operation arm 30 is mounted, the operation arm 30 is translated so that the link 33 is received in the mounting groove 213 from the side surface 211 of the body 210, so that the driving mechanism 34 of the operation arm 30 is adjacent to the power portion 220 in the receiving groove 214, and then the driving mechanism 34 is connected to the corresponding power portion.

In the embodiment shown in fig. 14 and 15, the surface of the body 210 with the receiving groove 214 is opposite to the bottom surface 212. The mounting groove 213 penetrates the bottom surface of the housing groove 214, that is, the mounting groove 213 penetrates the bottom surface of the housing groove 214 and the bottom surface 212 of the body 210 in the direction of the link 33 of the operation arm 30, so that the operation arm 30 can be mounted from the side surface of the body 210. The power portion 220 is disposed in the receiving groove 214, and a connection surface 221 of the power portion 220 connected to the operation arm 30 is a surface of the power portion 220 facing away from the bottom surface 212 of the body 210. At this time, the surface of the operation arm 30 connected to the power unit 220 is the surface of the driving mechanism 34 facing the bottom surface 212, for example, the operation arm 30 of the embodiment shown in fig. 6, and moves toward the bottom surface 212 and is engaged with the connection surface 221 when being mounted.

In the embodiment shown in fig. 16 and 17, the surface of the body 210 with the receiving groove 214 is the same as the surface with the mounting groove 213, that is, the opening of the receiving groove 214 is located on the side surface 211 of the body 210, and at this time, the mounting groove 213 penetrates through the first inner wall 215 of the receiving groove 214 close to the bottom surface of the body 210, so that the links of the operating arm can all extend out of the body 210 through the mounting groove. The power portion 220 is disposed in the receiving groove 214 and spaced apart from the first inner wall 215 to form a receiving area for receiving the power portion 220, and a connection surface 221 of the power portion 220 and the operating arm 30 is a surface of the power portion 220 facing the bottom surface 212 of the body 210. In this case, the surface of the operation arm 30 connected to the power unit 220 is the surface of the driving mechanism 34 facing away from the bottom surface 212, for example, the operation arm 30 of the embodiment shown in fig. 4, and moves away from the bottom surface 212 and engages with the connection surface 221 when mounted.

In the embodiment shown in fig. 18 and 19, the surface of the body 210 with the receiving groove 214 is opposite to the bottom surface 212.
