As shown in fig. 1, the present invention provides a surgical system 1000, wherein the surgical system 1000 comprises a surgical robot (not shown) and a sterile cover 101 covering the surgical robot. The surgical robot includes a master console 100 and a slave manipulation apparatus 200, the master console 100 for transmitting a control command to the slave manipulation apparatus 200 according to a manipulation by a doctor to control the slave manipulation apparatus 200; the slave operation device 200 is used for responding to the control command sent by the master console 100 and performing the corresponding operation. The slave manipulator 200 includes a post 21, a robot arm 22 suspended from the post 21, a power mechanism 23 provided on the robot arm 22, a surgical instrument (not shown), and an image display 25. The power mechanism 23 is accommodated in the housing 220, and is configured to receive the surgical instrument and provide an actuating force for the surgical instrument. The surgical system 1000 further includes a stab card (not shown) and a stab card holder 26 secured to the housing 220, the stab card holder 26 being adapted to hold the stab card for insertion of the surgical instrument through the stab card into the body. The surgical instrument may further include a surgical tool and an endoscope. The surgical tool is configured to be driven by the power mechanism 23 to extend into the body and perform a surgical operation via its distally located end effector. The endoscope acquires an in-vivo image by an image acquisition unit located at the distal end thereof. The image display 25 is used for displaying images acquired by the endoscope. Wherein, the sterile cover 101 of the surgical system shown by the dotted line is an integrally formed structure. That is, the aseptic enclosure 101 covers the column 21, the robot arm 22, and the power mechanism 23 at the same time. Of course, in other embodiments, the sterile cover 101 may be a split structure.

As shown in fig. 1, the sterile cover 101 includes a body 1, and an adaptor (not shown in the drawings) disposed on the body 1, where the body 1 is configured to cover at least one of the power mechanism 23, the mechanical arm 22, and the upright 21, so as to form a first surface a facing at least one of the power mechanism 23, the mechanical arm 22, and the upright 21, and a second surface b opposite to the first surface, where the first surface a is located in a non-sterile area, and the second surface b is located in a sterile area. The body 1 can be an integrally formed structure or a split structure. The details are the same as above, and are not described herein again.

It will be appreciated that the adaptor is not necessarily of a construction. In other embodiments, the sterile cover 101 may not include the adaptor.

As shown in fig. 2, the housing 220 is recessed with a fixed channel 225 for movement of the surgical instrument. The body 1 is provided with a first avoiding film 15 positioned in the fixed channel 225, and the first avoiding film 15 is used for providing an installation space for the surgical instrument to be installed on the power mechanism 23 and/or providing a moving space for the surgical instrument to move along the fixed channel 225. Specifically, the fixing channel 225 is used for receiving a connecting rod (not shown) of the surgical instrument, and when the power mechanism 23 receives the surgical instrument, the connecting rod is received in the fixing channel 225. When the power mechanism 23 provides an actuation force to the surgical instrument, the linkage moves within the fixation channel 225.

It is understood that in one embodiment, the first avoidance film 15 can be positioned outside of the fixed channel 225 and interfered with by the linkage into the fixed channel 225 when the surgical device is mounted to the power mechanism 23. In this case, the first avoiding thin film 15 is a flexible film, but the first avoiding thin film 15 may be a deformable hard film. In another embodiment, the first bypass film 15 can match the shape of the fixed channel 225 and be located in the fixed channel 225, in which case, the first bypass film 15 can be a flexible film or a rigid film.

As shown in fig. 2, the sterile hood 101 may further include a partition 14 for securing within the securing channel 225. The partition 14 is used to abut against the first bypass film 15 to fix the first bypass film 15 in the fixing channel 225, thereby providing the installation space and/or the moving space. It is understood that the partition 14 may be made of elastic plastic or metal, and the original shape of the partition 14 may be a flat plate, which is deformed when being installed in the fixing channel 225 to match the shape of the fixing channel 225. Of course, in other embodiments, the partition 14 may be a rigid structure without elasticity, and in this case, the initial shape of the partition 14 matches the shape of the fixing channel 225, and the initial shape is not deformed. For example, the shape of the partition 14 may be a hollow cylindrical shape or an unsealed hollow cylindrical shape. Since the fixing channel 225 is formed to have a large inside and a small outside, the partition 14 can be fixed in the fixing channel 225 without providing an additional fixing structure.

Further, as shown in fig. 3, the partition 14 includes a partition body 141 for being fixed in the fixing passage 225, and an extension 142 extending from the partition body 141. The extension portion 142 may be a telescopic structure, and may be in a contracted state before use, and the extension portion 142 may be pulled out during use, so as to save the space occupied by the partition portion 14. Of course, in other embodiments, the extension 142 may be a non-retractable structure. It is understood that the shape of the partition body 141 is as described above with respect to the partition 14, and thus, will not be described in detail.

As shown in fig. 4, the body 1 further includes a second bypass film 16 contacting the extension 142, and the extension 142 is configured to abut against the second bypass film 16 to form a moving channel 227 communicating with the fixing channel 225 when the separation body 141 is installed in the fixing channel 225, so as to provide an installation space for the surgical instrument to be installed on the power mechanism 23 and a moving space for the surgical instrument to move along the fixing channel 225 and the moving channel 227. It is understood that when the power mechanism 23 provides an actuating force to the surgical instrument to move the surgical instrument, the second avoiding film 16 deforms as the surgical instrument moves from the end of the extension 142 toward the partition 141, thereby providing the moving space for the surgical instrument. In this way, the need for sterilization of the slave operating device can be minimized or eliminated while ensuring proper operation of the slave operating device, thereby increasing the useful life of the slave operating device.

Further, as shown in fig. 3 and 5, the partition body 141 has a first side surface 143 and a second side surface 144 opposite to each other, the partition body 141 includes a fixing rod 145 disposed on the first side surface 143, the extending portion 142 includes a positioning portion 146 fixed on the second side surface 144, and the positioning portion 146 corresponds to the fixing rod 145. It is understood that the present embodiment is applicable to the case where the partition body 141 is an elastic structure. At this time, the fixing rod 145 is additionally provided to the partition body 141, so that the overall strength of the partition body 141 can be increased, and the partition 14 can be prevented from coming out of the fixing passage 225. In addition, the positioning portion 146 provided on the extension 142 can enhance the fixing strength of the extension 142 on the partition 141, thereby preventing the extension 142 from being broken during use.

Further, as shown in fig. 5, the positioning portion 146 has a stopping wall 147 facing to a side of the partition body 141, and the stopping wall 147 is used for interfering with the housing 220 to limit the partition body 141 from moving in the first direction X in the fixing passage 225. To further enhance the position limiting effect, as shown in fig. 6 and 7, a protruding structure 149 may be further protruded from the extending portion 142 at the position of the positioning portion 146, and the protruding structure 149 interferes with the housing 220 to limit the partition body 141 from moving in the first direction X in the fixing channel 225.

As shown in fig. 7, the housing 220 is further provided with a stopper 223 at a side close to the extending portion 142, and the stopper 223 is used for interfering with the first sidewall 148 of the partition body 141 at a side close to the extending portion 142 to limit the partition body 141 from moving in the second direction Y in the fixing channel 225. It can be understood that the separating body 141 is provided with a notch (not shown) at a position corresponding to the stopper 223 to accommodate the stopper 223. Further, the notch portion may have an L-shaped structure and have a first side wall 148 and a second side wall 180 adjacent to each other, and the first side wall 148 and the second side wall 180 respectively interfere with the stopper 223 to respectively prevent the separating body 141 from moving toward the second direction and prevent the separating body 141 from coming out of the fixing channel 225 in the gravity direction.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention that are made by using the contents of the specification and the drawings or directly/indirectly applied to other related technical fields are included in the scope of the present invention.
