[0002] Single-port laparoscopic surgery refers to a minimally invasive surgery in which an incision is made in a natural scar in the human body to perform laparoscopic operations.

[0003] In laparoscopic robotic surgery, a stable and reliable channel is required for the robot's operating rod to enter to ensure the smooth progress of the operation. However, the current inner diameter of the channel is usually a fixed size and cannot meet the requirements of the entry and exit of operating rods of different diameters. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0026] In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not indicate the importance of the components, and therefore cannot be understood as a limitation on the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution, and do not limit the scope of protection of the present invention.

[0027] like Figure 1 The embodiment of the present application discloses a laparoscopic robot channel, including a channel body 1, a hose 11 and a machine interface 2. The channel body 1 is provided with a plurality of auxiliary joints 621 for allowing cameras, suction devices and other instruments to enter; the channel body 1 is also provided with a trachea 61, and a valve is installed on the trachea 61 for inputting surgical gas into the channel through an insufflator.

[0028] like Figure 2 and Figure 3 The hose 11 is connected to the channel body 1 and the two are interconnected. The machine interface 2 is connected to the hose 11 for inserting the robot operating rod. The machine interface 2 includes a joint 21 and an adjustment ring 22. The joint 21 has a through-hole inside. An intermediate pipe 23 for the hose 11 to be sleeved is fixed at one end of the joint 21. The intermediate pipe 23 is coaxially distributed with the joint 21. The outer peripheral wall of the intermediate pipe 23 is provided with a threaded section, and the adjustment ring 22 is threadedly connected with the threaded section. An annular groove 231 is provided on the outer peripheral wall of the intermediate pipe 23. The groove 231 is located on the side of the threaded section away from the joint 21. A retaining ring 24 is provided on the inner peripheral wall of the hose 11. The retaining ring 24 is integrally formed with the hose 11, and the retaining ring 24 and the hose 11 are both elastic. The retaining ring 24 is inserted into the groove 231. The inner peripheral wall of the adjustment ring 22 is provided with a limiting groove 221 distributed along its circumference. The inner peripheral wall of the limiting groove 221 is against the outer peripheral wall of the hose 11.

[0029] The inner wall of the limiting groove 221 is pressed against the hose 11 , causing the hose 11 to undergo a certain elastic deformation. At the same time, the hose 11 is partially blocked by the adjusting ring 22 at the retaining ring 24 , limiting the separation of the retaining ring 24 from the slot 231 , thereby fixing the hose 11 to the intermediate tube 23 .

[0030] like Figure 2 and Figure 3 The end of the limiting groove 221 away from the joint 21 is provided with a chamfer 2211. When the adjusting ring 22 moves toward the end of the hose 11, the chamfer 2211 abuts against the outer circle of the end face of the hose 11, playing a guiding role, so that the hose 11 can be squeezed and deformed smoothly.

[0031] like Figure 2 and Figure 3 The outer wall of the hose 11 is provided with a circle of positioning ridges 111. When the adjusting ring 22 abuts against the positioning ridges 111, the end face of the hose 11 abuts against the bottom plane of the limiting groove 221. An elastic rubber ring 3 is provided on the outer sleeve of the intermediate tube 23. One end of the elastic rubber ring 3 abuts against the joint 21, and the other end abuts against the adjusting ring 22. The elastic rubber ring 3 is provided with a plurality of telescopic holes 31 extending along its radial direction. When the adjusting ring 22 abuts against the positioning ridges 111, the elastic rubber ring 3 is in a natural state.

[0032] In the initial state, the adjusting ring 22 is separated from the card slot 231, and the elastic rubber ring 3 is elastically deformed under the pressure of the adjusting ring 22; when the operator puts the hose 11 on the middle tube 23 and inserts the retaining ring 24 into the card slot 231, the adjusting ring 22 is twisted to move it closer to the hose 11, and the hose 11 is squeezed by the inner circumferential wall of the limiting groove 221 and tightly sealed with the middle tube 23. When the adjusting ring 22 abuts against the positioning convex ridge 111, it stops. At this time, the inner bottom plane of the limiting groove 221 is flush with the end face of the hose 11.

[0033] The telescopic hole 31 can generate sufficient deformation when the elastic rubber ring 3 is squeezed, providing movable space for the adjustment ring 22; when the elastic rubber ring 3 returns to its original state, it can limit the loosening of the adjustment ring 22 to a certain extent without artificial twisting.

[0034] like Figure 1 and Figure 2 A sealing film 4 for covering the opening is provided in the joint 21, and a cross-shaped opening slit 41 is provided on the sealing film 4. The sealing film 4 is provided with two layers, the two layers of sealing films 4 are attached to each other, and the opening slits 41 on the two sealing films 4 are staggered.

[0035] The machine operating rod is inserted from the opening slits 41 of the two sealing films 4. The sealing film 4 blocks the gap between the operating rod and the inner hole of the joint 21, thereby reducing the gas leakage to the outside. At the same time, the two opening slits 41 are cross-arranged to block each other.

[0036] When in use, the channel body 1 is also threadedly connected with the laparoscope channel 5, and the laparoscope channel 5 is interconnected with the channel body 1; the laparoscope channel 5 includes a terminal 51, a soft sleeve 52 and a sealing ring 53 connected in sequence, and the terminal 51 is threadedly connected with the channel body 1. During surgery, the sealing ring 53 is placed into the patient's abdominal cavity through the incision, the soft sleeve 52 is pulled to make the sealing ring 53 abut against the inner wall of the abdominal cavity, and then the excess part of the soft sleeve 52 is folded to cover the incision to achieve sealing of the incision; the machine operating rod is inserted from the machine incision, and the operation is performed in the abdominal cavity through the laparoscope channel 5; medical staff can replace the machine interface 2 with different inner diameters according to the size of the machine operating rod to be used before the operation to meet different surgical needs.

[0037] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
