Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

as shown in fig. 1 to 3, a laparoscopic liver suspension apparatus includes a sleeve 1, a fixed plate 2 and a guide rod 3, the fixed plate 2 is movably disposed on the sleeve 1, and the guide rod 3 is disposed in the sleeve 1; the upper end of the guide rod 3 extends out of the sleeve 1 and is provided with a holding disc 4, the guide rod 3 extending out of the sleeve 1 is sleeved with a first spring 6, the lower end of the guide rod 3 is provided with a suspension disc 10 matched with the inner diameter of the sleeve 1, the bottom surface of the suspension disc 10 is hinged with a plurality of suspension claws 11, and the suspension claws 11 can completely extend out of the lower end of the sleeve 1 and are opened to different angles in the direction perpendicular to the guide rod 3.

As shown in fig. 1, the sleeve 1 is a hollow circular tube, the upper end of the sleeve is closed, the lower end of the sleeve is open, and the upper end of the guide rod 3 penetrates through the closed end of the sleeve 1; the upper end of the outer side surface of the sleeve 1 is symmetrically provided with holding frames 5 used for being matched with the holding disc 4, the holding disc 4 is pressed downwards by a palm with strength, so that the first spring 6 is compressed, the guide rod 3 moves downwards, and after the holding disc 4 is close to the holding rod, the holding disc 4 and the holding rod are held by palm and fingers, so that the labor-saving effect is achieved. In this embodiment, the bottom surface of the holding rod is configured to be concave to match with fingers, so as to facilitate use. The outer side of sleeve 1 is located to the fixed disk 2 cover, and one section that sleeve 1 lateral surface is close to the lower extreme is provided with the external screw thread, and fixed disk 2 is connected with sleeve 1's lateral surface through the screw thread to realize that the stationary blade reciprocates on sleeve 1.

As shown in fig. 2, an elastic pin 7 is arranged on the guide rod 3 near the upper end of the sleeve 1, a pin hole 8 matched with the elastic pin 7 is arranged on the sleeve 1, and the pin hole 8 is arranged below the elastic pin 7; the pin hole 8 is disposed below the elastic pin 7 by a vertical distance not greater than the distance the first spring 6 can compress. The elastic pin 7 comprises a second spring 71 and a round-head pin 72, one end of the second spring 71 is connected with the guide rod 3, the other end of the second spring 71 is connected with the round-head pin 72, when the guide rod 3 moves downwards, the round-head pin 72 moves to the position of the pin hole 8, and under the action of the elastic force of the second spring 71, the round-head pin 72 can pop out of the pin hole 8, so that the movement of the guide rod 3 is limited. Articulated on the sleeve 1 have a pressing plate 9, the lower extreme that presses plate 9 to be close to the side of sleeve 1 is provided with presses round pin 91, press the position that round pin 91 set up just right pinhole 8, when pressing plate 9, press round pin 91 can press into sleeve 1 from pinhole 8 to button head pin 72 in, under the effect of the elastic force of first spring 6, guide rod 3 upwards removes.

As shown in fig. 3, the suspension claws 11 are arranged in the sleeve 1, third springs 12 are arranged between the suspension claws 11 in a pressed state, and torsion springs are arranged between the suspension claws 11 and the suspension plate 10 to make the suspension claws 11 perpendicular to the guide rod 3. When the guide rod 3 moves downwards and the round-head pin 72 is popped out of the pin hole 8, the suspension plate 10 just extends out of the lower end of the sleeve 1, and the suspension claw 11 rotates upwards to a horizontal position under the action of the elastic force of the torsion spring, so that the suspension claw 11 is in a state of being vertical to the guide rod 3; meanwhile, the suspension claws 11 are opened at different angles from each other by the elastic force of the third spring 12, so that the suspension claws 11 are formed in a fan shape as a whole. In this embodiment, the elastic force of the first spring 6 can pull the suspension claws 11 extending out of the sleeve 1 back into the sleeve 1, that is, after the round-head pin 72 is pressed into the sleeve 1, the elastic force of the first spring 6 can pull the suspension claws 11 extending out of the sleeve 1 back into the sleeve 1; of course, the lower end of the sleeve 1 may also be designed in the form of a bell 13 to ensure that the suspension platform 10 can be accurately retracted into the sleeve 1.

In the embodiment, the section of the fixed disk 2 is circular, and the diameter of the fixed disk is 40-50 mm; the section of the guide rod 3 is circular, and the diameter of the guide rod is 3-5 mm; the cross section of each suspension claw 11 is circular or rectangular, the diameter or the width of each suspension claw is 1mm, the number of the suspension claws 11 is four, and the angle formed by the four suspension claws 11 when the four suspension claws 11 are opened is 60 degrees.

When the device is used, under a laparoscope, the position of the liver is determined, a specific position is selected on the abdominal cavity for puncturing, and the suspension device is sent into the abdominal cavity through the puncturing hole, particularly to the lower part of the edge of the liver; slowly pressing the holding disc 4 until the hanging claws 11 completely extend out of the sleeve 1 and are opened, placing the fan-shaped structure formed by the hanging claws 11 under the liver, hanging the liver and exposing the operation visual field; the fixing disc 2 is moved downwards to a position tightly attached to the abdomen, and the medical adhesive tape is used for adhering to fix the position of the fixing disc 2, so that the suspension of the liver under the laparoscope is completed, and the scratch of the liver in the operation is effectively avoided.

However, it should be noted that the suspension device is only described as an example for suspending the liver, and the device can be used as long as it has enough space for operation in order to limit the use of the device only for suspending the organ of the liver.
