And the docking unit of the oviduct is used for controlling the back-up of the inflation tube 15 on the first supporting structure 11 from the laparoscope, driving the first section of the oviduct 51 supported by the first supporting structure 11 to move, controlling the first supporting structure 11 to move towards the second supporting structure 12 until the first supporting structure 11 is docked with the second supporting structure 12, and simultaneously realizing the docking of the first section of the oviduct 51 and the second section of the oviduct 52 supported by the first supporting structure 11 and the second supporting structure.
A oviduct stitching unit, which is used for controlling a stitching instrument entering from the laparoscope to finish stitching the butted oviduct under the laparoscope;
The recapture instrument withdrawing unit controls the balloon portions 14 of the two support structures to be deflated, then controls the forward pushing of the conveying pipe 2, simultaneously controls the backward withdrawing of the inflation pipe 15 of the second support structure 12 so that the second support structure 12 enters the conveying pipe 2, continuously controls the backward withdrawing of the inflation pipe 15 until the second support structure 12 completely enters the conveying pipe 2, then pushes the conveying pipe 2 forward and simultaneously withdraws the inflation pipe 15 of the first support structure 11 so that the first support structure 11 enters the conveying pipe 2, continuously withdraws the inflation pipe 15 until the first support structure 11 enters the position originally in the conveying pipe 2, and then withdraws the conveying pipe 2 outside the body. Preferably, the second support structure 12 is controlled to withdraw to a position initially at the delivery tube 2.
The more preferable implementation mode is that the delivery tube 2 placement unit is controlled to stop after the delivery tube 2 reaches a position 1-3mm away from the edge of the first section of oviduct 51 under the observation of a laparoscope, the first support structure 11 placement unit controls the pushing-out structure to enable the distance between the first end part of the first support structure 11 and the edge of the first section of oviduct 51 to be 1-3mm when the first support structure is close to the first end of the edge of the first section of oviduct 51, the second support structure 12 placement unit controls the end part of the delivery tube 2 to reach a position 1-3mm away from the edge of the second section of oviduct 52, specifically, the delivery tube 2 starts when the laparoscope observes that the delivery tube 2 retreats to the second section of oviduct 52, the movement distance of the delivery tube 2 is observed in vitro and is cut off until the length of one support structure is increased by 1-3mm, the delivery tube 2 is controlled to be pushed out of the second support structure 12.
While the foregoing embodiments of the present invention have been described in terms of specific embodiments, it will be apparent to those skilled in the art that the foregoing embodiments are merely illustrative of some, but not all, of the present invention, and that other advantages and features of the present invention will be readily apparent to those of ordinary skill in the art from consideration of the specification. The invention may be embodied or applied in other specific forms without conflict, the present embodiments may be controlled by a person of ordinary skill in the art, without any exercise of inventive faculty, to obtain all other embodiments, based on the embodiments of the invention, from which the features of the embodiments described above may be combined.
