When the pair of handles 5 are close, the opening and closing of the arc-shaped blades 3 are controlled by controlling the distance between the two handles 5, which causes the separation of the opening and closing arms 4.
The inner edge sawteeth 8 and the outer edge sawteeth 8 are mutually embedded into each other in a joint mode between the adjacent arc-shaped blades 3, when the force is applied outwards, the inner edge sawteeth 8 and the outer edge sawteeth 8 slide mutually, and the circular hole tunnel can be expanded and fixed and is used for supporting a minimally invasive opening pore passage; when the force is applied inwards, the sawteeth 8 on the inner edge and the outer edge are loosened, and the circular hole tunnel is loosened, so that the circular hole tunnel is convenient to take out from the minimally invasive opening pore passage.
The expanding caliper 2 is vertically connected with the long axis direction of the arc-shaped blade 3 through a front arm. A latch structure 7 is arranged between the two handles 5 of the expanding caliper 2 and used for fixing the distance between the two handles 5.
The expanding caliper 2 and the arc-shaped blades 3 are made of high-strength rigid metal materials.
The connecting point is provided with a movable shaft.
As shown in fig. 1, when the invention is used, one or more groups of distraction units 1 are combined for use, and taking a four-leaf type distraction device consisting of two groups of distraction units 1 as an example, the two groups of distraction units 1 are overlapped and assembled in a crossing way.
As shown in fig. 2, the spreader unit 1 is composed of a spreader caliper 2 and arc-shaped blades 3. One end of the distraction caliper 2 is provided with a distraction arm 4, the other end is provided with a handle 5, the distraction arm 4 is integrally connected with the handle 5 to form an S-shaped structure, the two S-shaped structures are in cross connection by virtue of a joint 6, and when a pair of handles 5 approach, the distraction arm 4 can be separated; when the opening and closing device is applied to opening a pore channel, the arc-shaped blade 3 is sequentially connected with the opening arm 4, the movable joint 6, the latch structure 7 and the handles 5 from inside to outside, and the opening and closing process of the arc-shaped blade 3 can be controlled by controlling the distance between the two handles 5; when the arc-shaped blades 3 are connected for use, the arc-shaped blades 3 are vertically placed in the thoracoabdominal cavity incision duct, the distraction calipers 2 are arranged outside the duct, and the distraction calipers 2 are alternately stacked on the body surface. After the upper and lower edges of the arc-shaped blade 3 are aligned, the left and right edges surround a circular hole tunnel in a imbricate shape. The latch structure 7 is arranged between the two handles 5 and used for fixing the distance between the two handles 5 after being toothed.

When the arc-shaped blades 3 are stressed inwards, the latch of the adjacent arc-shaped blade 3 is separated, the action of the upper teeth disappears, and the relative position of the arc-shaped blades 3 is restored to be before the upper teeth.
The invention is characterized in that the integral connection of the distraction units is completed by manufacturers, and the application process of the expansible specimen extractor for the pleuroperitoneal cavity mirror operation is explained as follows: taking a four-blade type spreader consisting of two groups of spreading units 1 as an example of the use condition, the sequence of using the device is as follows: firstly holding a propping unit 1, opening a handle 5 to enable the two units to be in a close state, placing a vertical cut into a pore channel, placing a propping caliper 2 on the body surface, properly closing the handle 5, and properly propping the cut through a latch structure 7; holding another opening unit 1, embedding the opening unit 1 into the incision in the same way, overlapping the second opening unit 1 on the first opening unit 1 in a crossed manner, appropriately carrying out tooth feeding to enable the four imbricated shapes to form a circular hole tunnel, then, when the circular hole tunnel needs to be expanded continuously, synchronously folding the handles 5 of the two opening units 1 by two hands, carrying out tooth feeding on the opening calipers 2 by controlling a latch structure 7, leading the stress to be outward and to move mutually at the moment to cause the circumference of the circular hole tunnel to be increased gradually, ensuring that the circular hole tunnel is always cylindrical during expansion at the moment, facilitating the sample to be taken out and pass through, and simultaneously ensuring that the radius of the opening circular hole tunnel is fixed and does not rebound by the latch on the left and the right; when the specimen is removed, the latch structure 7 is released and the handle 5 is opened to move the arcuate blades 3 towards each other, at which point the device can be withdrawn from the incision.
In the case of complex incision requiring expansion, the three or four expanding units 1 can also form a "six-leaf type" or "eight-leaf type" expander, and the use process is the same as above and is not described again. Besides the combination use, the expanding unit 1 also has unexpected application value when being used alone, for example, the expanding unit 1 can be used as a simple expander and is suitable for expanding deep tunnels with low requirements.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention in any way, and any person skilled in the art can make any simple modification, equivalent replacement, and improvement on the above embodiment without departing from the technical spirit of the present invention, and still fall within the protection scope of the technical solution of the present invention.
