The background technology is as follows:

after the world first example laparoscopic surgery is completed in 1987, along with the continuous improvement of laparoscopic equipment and instruments, the laparoscopic technology is continuously improved, the laparoscopic surgery is vigorously developed, and the adaptation is gradually expanded. Now, the operation of all organs in the abdominal cavity can be performed by means of laparoscopic surgery. When laparoscopic surgery is performed on upper abdominal organs such as the stomach, pancreas, etc., the left liver of a normal person often affects the appearance of the surgical field in order to keep the left liver open.

In the prior art, the problems of liver injury, infection, postoperative transaminase rise and the like are caused by unstable operation of directly pushing and picking the liver by the liver retractor or clamping the yarn cloth by other instruments, and the surgical operation can be influenced by crisscross instruments in the abdominal cavity and mutual interference, and the posture of the liver can not be regulated again according to the needs in the operation.

The application comprises the following steps:

the application aims to overcome the defects in the prior art and provides a device for exposing the upper abdomen in laparoscopic surgery.

The application provides the following technical scheme:

a device for laparoscopic surgical epigastric exposure comprising a fixed support and a lifting member, characterized in that: the lifting part comprises a horizontal section, one end of the horizontal section is connected with a longitudinal section, a bending part is arranged on the horizontal section, a first arc-shaped part is arranged at one end of the bending part, a second arc-shaped part is arranged at the other end of the bending part, a section of spring is respectively arranged on the first arc-shaped part and the second arc-shaped part, and at least one control rope is clamped on each section of spring.

On the basis of the technical scheme, the following further technical scheme is also available:

the medical sterile rope of control rope has two knots of interval distribution in control rope one end tip, and the rope body between two knots forms joint cooperation with the spring, and this rope body leaves the surplus of removal on the spring.

The fixing support comprises a clamping groove which is connected with the operating table, a vertical rod is arranged on the clamping groove, a cross connecting piece is arranged on the vertical rod and connected with a cross rod, and a universal clamp which is connected with the longitudinal section in a matched mode is connected on the cross rod.

The horizontal section and the longitudinal section are of an integrated structure and are made of medical stainless steel.

The spring wires of the springs are mutually attached, so that the springs are integrally of a tension spring type structure and are made of medical stainless steel.

The application has the advantages that:

the application has the advantages of convenient use, simple operation, adjustable liver posture and convenient adjustment, and other parts except the contact of the control rope and the liver are not contacted with the liver in the operation process, thereby effectively avoiding the problems of damage, postoperative infection, transaminase rise and the like caused by the direct contact of the traditional liver retractor and the liver.

Description of the drawings:

FIG. 1 is a schematic view of the structure of a lifting member of the present application;

FIG. 2 is a schematic view of the application in use with a lifting member;

fig. 3 is a schematic view of the lifting element connected to the fixed support.

The specific embodiment is as follows:

as shown in fig. 1-3, a device for exposing the upper abdomen of a laparoscopic surgery comprises a fixed bracket 8 and a lifting part in matched connection, wherein the lifting part comprises a strip-shaped horizontal section 1, the horizontal section 1 comprises a first arc-shaped part 4, a bending part 3 which is distributed corresponding to hepatic ligaments extends from one end of the first arc-shaped part 4, and a second arc-shaped part 5 extends from one end of the bending part 3. The first arc-shaped part 4 and the second arc-shaped part 5 are respectively sleeved with springs 6 which are correspondingly and coaxially distributed, and spring wires of the springs 6 are mutually attached, so that the springs 6 are integrally in a tension spring type structure.

The end of the second arc-shaped part 5 extends upwards to form a strip-shaped longitudinal section 2, the longitudinal section 2 comprises a first longitudinal arc-shaped part a, one end of the first longitudinal arc-shaped part extends to form a horizontal part b which is transversely distributed, and the end of the horizontal part b is slightly tilted upwards. The horizontal section 1 and the longitudinal section 2 are of an integrated structure and are made of medical stainless steel as well as the spring 6.

A plurality of medical sterile ropes are arranged as control ropes 7, two knots 7a which are distributed at intervals are tied at one end part of each control rope 7, a rope body between the two knots 7a is longer (the diameter larger than the spiral diameter of the spring 6) and can be clamped between spring wires of the spring 6, one end part of each control rope 7 can be clamped through the spring wires, and the control ropes 7 are adjusted in a mode that the knots 7a are pulled by a surgical instrument.

The fixing support 8 comprises a clamping groove 8a, a locking bolt 8f which is in locking fit with the operating table is arranged on one side of the clamping groove 8a in a penetrating mode, a vertical rod 8b which is vertically distributed is fixedly connected to the other side of the clamping groove 8a, a transverse rod 8d which is transversely distributed is connected to the vertical rod 8b through a cross-shaped connecting piece 8c, and a universal clamp 8e is connected to one end of the transverse rod 8 d. The universal clamp 8e comprises a connecting part 18a inserted into the cross rod 8d, an insertion hole matched with the cross rod 8d is formed in the connecting part 18a, a locking pin 18b matched with the cross rod 8d is further arranged on the connecting part 18a, a swing arm 18c is connected to the ball head of the connecting part 18a, a corresponding matched mounting hole is formed in the swing arm 18c and corresponds to the horizontal part b, and a tightening pin matched with the horizontal part b in a locking mode is arranged on the swing arm 18 c.

The using method comprises the following steps:
