Background

The vessel forceps are medical instruments commonly used in clinical medical treatment, and are mainly used for clamping blood vessels or bleeding points, and have the functions of separating anatomical tissues and clamping skin, visceral organs and tissue blood vessels. The existing vascular clamps generally comprise a clamp mouth, a hinged shaft, a clamp arm and a finger ring, and when in operation, the clamp mouth and the clamp arm move in the body in the same direction. Because the forceps mouth is opened, the operation space in a human body is limited, the forceps mouth cannot enter a deep depth, and the problem of inconvenient operation due to a long distance can occur to the blood vessel at a long distance from the operation incision. In addition, the existing vascular clamps are point-clamped, and a plurality of surgical incisions are required to obtain a certain length of blood vessel, so that the mode cannot meet the requirements of the existing minimally invasive surgery.

Disclosure of Invention

The technical scheme adopted by the invention for solving the technical problems is as follows:

a long-axis type strip venous vessel forceps comprises a first forceps arm and a second forceps arm, wherein one end of the first forceps arm and one end of the second forceps arm are respectively provided with a first finger ring and a second finger ring which correspond to each other, the other end of the first forceps arm is connected with a strip-shaped first clamping plate, the other end of the second forceps arm is connected with a strip-shaped second clamping plate, the first clamping plate is perpendicular to the first forceps arm, and the second clamping plate is perpendicular to the second forceps arm; the first clamping plate and the second clamping plate are hinged through a hinge shaft to form a hinge structure;

the two ends of the first clamping plate are respectively provided with a first binding clip and a second binding clip, the two ends of the second clamping plate are respectively provided with a third binding clip and a fourth binding clip, the first binding clip is matched with the third binding clip, the second binding clip is matched with the fourth binding clip, and the sizes of the first binding clip and the third binding clip are larger than those of the second binding clip and the fourth binding clip.

Furthermore, the first binding clip, the second binding clip, the third binding clip and the fourth binding clip are all arc-shaped sheets, the inner arc surfaces of the first binding clip and the third binding clip are correspondingly matched, and the inner arc surfaces of the second binding clip and the fourth binding clip are correspondingly matched.

Furthermore, the outer edges of the first binding clip, the second binding clip, the third binding clip and the fourth binding clip are arc-shaped.

Furthermore, the inner arc surfaces of the first binding clip and the third binding clip are respectively provided with a first convex rib which forms mutual occlusion, and the inner arc surfaces of the second binding clip and the fourth binding clip are respectively provided with a second convex rib which forms mutual occlusion.

The invention has the advantages that the clamp plate which is vertical to the clamp arm is arranged, the hinge structure controlled by the clamp arm is formed, the two ends of the clamp plate are provided with the clamp heads, during the operation, the clamp arm is operated to lead the clamp heads to clamp the vein blood vessel along with the opening or closing of the clamp plate, the length directions of the clamp plate and the clamp heads are vertical to the clamping direction of the operation clamp arm, and the clamp plate and the clamp heads can move along the direction of the blood vessel, thereby being capable of entering the blood vessel far away from the incision of the operation to perform the operation; because the forceps head is arc-shaped, the forceps head is more fit with the appearance of a blood vessel, and the blood vessel can be stripped during movement; the clamp heads on the two sides of the splint have different sizes and can be suitable for blood vessels with different thicknesses;

through the arrangement of the convex ribs which are matched with each other, the friction force between the forceps head and the blood vessel can be increased, and the slippage of the blood vessel in the operation process can be avoided.

Detailed Description

Referring to fig. 1 and 2, the invention provides a long-axis type strip venous vessel forceps, which comprises a first forceps arm 1 and a second forceps arm 2, wherein one end of the first forceps arm 1 and one end of the second forceps arm 2 are respectively provided with a corresponding first finger ring 3 and a corresponding second finger ring 4, the other end of the first forceps arm 1 is connected with a strip-shaped first splint 5, the other end of the second forceps arm 2 is connected with a strip-shaped second splint 6, the first splint 5 is perpendicular to the first forceps arm 1, and the second splint 6 is perpendicular to the second forceps arm 2; the first clamping plate and the second clamping plate are hinged through a hinge shaft 7 to form a hinge structure. Preferably, the first clamp plate 5 and the first caliper arm 1 are integrally formed, and the second clamp plate 6 and the second caliper arm 2 are integrally formed.

The two ends of the first clamping plate 5 are respectively provided with a first binding clip 8 and a second binding clip 9, the two ends of the second clamping plate 6 are respectively provided with a third binding clip 10 and a fourth binding clip 11, the first binding clip, the second binding clip, the third binding clip and the fourth binding clip are all arc-shaped sheets, the inner arc surfaces of the first binding clip 8 and the third binding clip 10 are correspondingly matched, and the inner arc surfaces of the second binding clip 9 and the fourth binding clip 11 are correspondingly matched. The sizes of the first binding clip and the third binding clip are larger than those of the second binding clip and the fourth binding clip. The outer edges of the first binding clip, the second binding clip, the third binding clip and the fourth binding clip are all arc-shaped.

The inner arc surfaces of the first binding clip and the third binding clip are respectively provided with a first convex rib 12 which forms mutual occlusion, and the inner arc surfaces of the second binding clip and the fourth binding clip are respectively provided with a second convex rib 13 which forms mutual occlusion.

Referring to fig. 3, during surgery, the forceps arms are operated to open or close the forceps heads along with the clamping plates to clamp the vein 14, and the length directions of the clamping plates and the forceps heads are perpendicular to the clamping direction of the forceps arms and can move along the direction of the vein, so that the forceps arms can go deep into the vein far away from the surgical incision to perform surgery; the depth of operation is determined by the length of the clamping plate, that is, the length of the hinge shaft, and can be flexibly set as required. Because the forceps head is arc-shaped, the forceps head is more fit with the appearance of a blood vessel, and the blood vessel can be stripped during movement; the clamp heads on the two sides of the splint have different sizes and can be suitable for blood vessels with different thicknesses; through the arrangement of the convex ribs which are matched with each other, the friction force between the forceps head and the blood vessel can be increased, and the slippage of the blood vessel in the operation process can be avoided.

In addition, the clamping of the forceps head and the splint to the blood vessel is changed into long-axis type surface clamping, so that the length of the clamped blood vessel is increased, the length of the obtained blood vessel is increased, and the operation incision is reduced.
