FIGS. 1-3 are schematic structural views of a mesh device for use in minimally invasive surgery; fig. 4-5 are schematic views of the structure of the retaining member.

In some alternative embodiments, as shown in fig. 1-2, a mesh device for minimally invasive surgery comprises a mesh body 1, a weight 2, a border 3, and a cinch ring 4, wherein: the gravity piece 2 is arranged at one end of the net body 1; the sideline 3 is arranged on the periphery of the net body 1, the free end of the sideline 3 penetrates through the closing ring 4, and the net body 1 is folded under the action of the sideline 3 and the closing ring 4 by pulling the free end of the sideline 3.

Therefore, during the minimally invasive surgery, the net device is placed in the body of a patient through the surgery opening, the gravity piece 2 of the net device falls to the back abdominal wall of the patient due to the self gravity, the free end of the sideline 3 of the net device is pulled, the net device is folded under the action of the sideline 3 and the closing ring 4, soft tissues which are located in a surgery operation area and do not need to be subjected to surgery operation are folded, and the interference of the normal surgery operation of a doctor is avoided.

In some alternative embodiments, the material of the border wire 3 is an elastic material, such as rubber, latex, silicone, etc. On one hand, the sideline 3 has elasticity, and the damage of the sideline 3 to human tissues can be reduced to a certain extent; on the other hand, do not pull under the condition of sideline 3 at medical personnel, sideline 3 resumes elastic deformation, and then can strut net body 1 for net body 1 and human tissue separation are convenient for take out the net device from the human body after the operation.

In some alternative embodiments, the weight 2 is a lead wire. Here, the lead wire is the line that the little lead section was worn with the line, and the lead wire has certain gravity, can play limiting displacement, can make net body 1 have good sense of hanging down moreover, and the soft tissue that will influence the operation that can be better draws in. Optionally, the diameter of the lead wire has a value range of [5mm, 6mm ], and is suitable for surgical openings of minimally invasive surgery.

In some alternative embodiments, as shown in fig. 3, a plurality of gravity elements 2 are arranged in sequence along the end of the net body 1. Here, set up a plurality of gravity pieces 2 for the flexibility that the net device was placed is higher, can paste human tissue and place, can not too much occupy the operation space.

In some alternative embodiments, as shown in fig. 1-3, the net structure further comprises a locking member 5 for locking the free end of the edge 3. Optionally, as shown in fig. 4-5, the locking member 5 includes a locking member body 51, a locking portion 52 and a spring 53 connected to the locking end of the locking portion 52, the locking end of the spring 53 and the locking portion 52 are disposed inside the locking member body 51, the locking member body 51 is provided with a through hole 511, the free end of the sideline 3 passes through the through hole 511, and under the action of the spring 53, the locking end of the locking portion 52 is pressed into the through hole 511 to lock the free end of the sideline 3. In actual use, the pressing end of the locking part 52 is pressed to compress the spring 53, so that the locking end of the locking part 52 is separated from the through hole 511, and the free end of the sideline 3 passes through the through hole 511; when the external force is removed, the spring 53 is restored to be deformed, the locking end of the locking portion 52 is pressed into the through hole 511, the locking end of the locking portion 52 is pressed against the locking member body 51, and the free end of the sideline 3 between the locking end of the locking portion 52 and the locking member body 51 is locked.

Here, when the free end of the sideline 3 passes through the through hole 511 of the locking member body 51 first, the through hole 511 of the locking member body 51 is equivalent to the binding off ring 4 at this time, the net body 1 is folded under the action of the sideline 3 and the through hole 511 of the locking member body 51, and the locking member 5 locks the free end of the locking sideline 3, so as to avoid other deformation after the net body 1 is folded; when the free end of sideline 3 passed the binding off ring 4 earlier, net body 1 draws in under sideline 3 and binding off ring 4's effect, and retaining member 5 locks the free end locking of locking sideline 3, and with binding off ring 4 combined action, avoids net body 1 to draw in the back and take place other deformations again.

Therefore, after the medical staff utilizes the net device to fold the soft tissue influencing the operation, the medical staff can keep the folded state of the net body 1 without pulling the free end of the sideline 3 by hands, thereby releasing the manpower and facilitating the operation.

In some alternative embodiments, as shown in fig. 1 and 3, the net body 1 has a semi-circular or semi-elliptical shape. Thus, the periphery of the net body 1 adopts an arc structure, and the damage to human tissues can be reduced to a certain extent.

In some optional embodiments, the shape of the grid of the net body 1 is square or circular, the structure of the net body 1 is more neat, the stress is uniform, and the structural performance is better.

In some specific optional embodiments, when the shape of the grid is square, the length of the side of the grid is in a range of [4mm, 5mm ]; when the shape of the grid is circular, the diameter of the grid is in a value range of [4mm, 5mm ]. Therefore, the maximum length of the grid is controlled within the range of [4mm, 5mm ], and the stability of the structure of the net body 1 is ensured under the condition of not influencing the normal respiration of human tissues.

In some optional embodiments, the mesh wires constituting the mesh body 1 are made of a transparent material, such as transparent soft glue. Therefore, a doctor can observe the real-time state of the human tissue folded by the net body 1, and the condition that the soft tissue to be operated is folded to influence the normal operation of the operation is avoided.

In some optional embodiments, the mesh wires constituting the mesh body 1 are made of an elastic biocompatible material, such as polyacrylamide hydrogel or diamond-like film, which has a slight reaction with the body of the patient and does not cause secondary damage to the body.

In some alternative embodiments, the outer layer of the border 3 is covered with a latex layer or a silica gel layer. Like this, because the compliance on emulsion layer and silica gel layer is better, can alleviate the injury that the pull sideline 3 caused to human tissue to a certain extent.

It is to be understood that the present invention is not limited to the procedures and structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
