Description

Surgical liver support device

technical field

The utility model belongs to the technical field of surgical instruments, in particular to a liver support device for surgery.

Background technique

In surgery, when the right liver occupying lesion is resected, it is usually very difficult to expose the liver because the position is too deep, and it is difficult to observe the liver, which is not conducive to the operation. Surgical grasping forceps, liver lobe forceps, etc. are used to turn the liver to expose the lesion of the liver, thereby increasing the field of view of the operation, but when turning the liver with these instruments, it often occurs due to piercing the liver or tearing the tissue Bleeding brings misery to the patient and increases the intensity and difficulty of the doctor's operation.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to provide a liver support device for surgery, which is simple and convenient to operate, the liver is fully exposed, and it is not easy to damage the liver and other tissues, which improves the efficiency of the doctor's operation and the safety of the patient, and reduces the The intensity and difficulty of surgery.

The purpose of this utility model is achieved in the following way: a liver supporting device for surgery, the key of which is: comprising a liver supporting plate, the liver supporting plate is in an isosceles trapezoidal shape, and both sides of the liver supporting plate are provided with baffles, the baffles Arranged along both side edges of the liver support plate, the blocking frame includes connecting rods and longitudinal bars evenly distributed on the edge of the liver support plate in the eye, each of the longitudinal bars is arranged in parallel, and one end of the longitudinal bar is fixed to the edge of the liver support plate link, and the other end is fixedly linked with the connecting rod.

With the above-mentioned structure, after inserting the liver support device under the liver, the liver is slowly lifted out to expose the liver, and the brackets on both sides of the liver support plate can not only limit the liver stably in the liver support plate, At the same time, it will not affect the exposure of the lesion, which improves the vision of the doctor's operation, improves the efficiency and effect of the operation, and the contact area between the device and the liver is large, which is not easy to cause the danger of puncturing the liver or tearing the tissue, and improves the operation efficiency. security.

The above-mentioned connecting rods, the longitudinal rods and the sides of the liver-supporting plate are in the same plane, and the lengths of each of the longitudinal rods gradually decrease from the wide end to the narrow end of the liver-supporting plate.

Since the liver is in a shape that gradually shrinks from one end to the other, the above-mentioned structure enables the liver supporting device to adapt to the shape of the liver as a whole, ensuring the storage space of the liver while minimizing the extrusion of the device on other tissues.

The above-mentioned longitudinal rod forms an included angle α of 90-135 degrees with the bottom edge of the isosceles trapezoidal liver-supporting plate, and the said connecting rod forms an included angle β of 15-45 degrees with the side of the liver-supporting plate.

By adopting the above-mentioned structure, the baffle frame is stretched toward both sides of the liver supporting plate as a whole, so as to increase the field of view of operation, but it is not stretched too far, so as to prevent excessive compression on the tissues around the liver.

Each of the longitudinal rods is arc-shaped, the concave surface of the longitudinal rod points to the narrow end of the liver support plate, and the longitudinal rods are telescopic support rods.

With the above-mentioned structure, when the longitudinal rod is pulled up or contracted, the effective area of the whole frame can be increased, and at the same time, the angle between the connecting rod and the side of the liver support plate can be adjusted to adapt to livers of different sizes.

The above-mentioned liver supporting plate is a telescopic base plate, and the connecting rod is a telescopic connecting rod. A longitudinal rod is connected between the corresponding telescopic joints, and the two ends of the longitudinal rod are respectively connected with the side of the telescopic joint of the support plate and the center of the telescopic joint of the connecting rod.

With the above-mentioned structure, the length of the entire liver supporting device can be adjusted by adjusting the synchronous expansion and contraction of the liver supporting plate and the connecting rod, so as to further adapt to livers of different sizes.

Beneficial effect:

The utility model is a liver support device for surgery, which does not excessively squeeze the surrounding tissue, is not easy to cause damage to the liver, and at the same time can fully expose the liver, expand the field of vision of the doctor's operation, improve the efficiency and effect of the operation, and improve the safety of the operation. Not only can it be adapted to livers of different sizes, but it can also improve the range of application of the device.

Detailed ways

Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

Example:

As shown in Figures 1, 2 and 3: a liver supporting device for surgery, consisting of a liver supporting plate 1 and brackets 2 arranged on both sides of the liver supporting plate 1, the liver supporting plate 1 is in an isosceles trapezoidal shape. The blocking frame 2 is arranged along the two side edges of the liver supporting plate 1, and the blocking frame 2 is composed of connecting rods 2a and longitudinal rods 2b evenly distributed on the edge of the liver supporting plate 1 in the eye, and each of the longitudinal rods 2b is arranged in parallel, so One end of the longitudinal rod 2b is fixedly connected with the edge of the liver support plate 1, and the other end is fixedly connected with the connecting rod 2a.

The side of the connecting rod 2a, the longitudinal bar 2b and the liver support plate 1 are in the same plane, and the length of each of the longitudinal bars 2b decreases successively from the wide end to the narrow end of the liver support plate 1; The bottom edge of the waist trapezoidal liver support plate 1 forms an angle α of 135 degrees, and the connecting rod 2a and the side of the liver support plate 1 form an angle β of 30 degrees. Of course, the size of α can also be 90, 105, 110 or 130 degrees, etc., the size of β can also be 15, 20, 25, 30 or 35 degrees, etc., as long as it can ensure that the liver supporting device adapts to the shape of the liver as a whole, fully exposes the liver, and does not squeeze the surrounding tissues too much Each of the longitudinal rods 2b is arc-shaped, the concave surface of the longitudinal rods 2b points to the narrow end of the liver support plate 1, and the longitudinal rods 2b are telescopic support rods.
