Problems solved by technology

[0004] In the process of partial nephrectomy, it is often necessary to dissociate the whole kidney. Generally, it is necessary to separate the kidney and the perirenal fat capsule dorsally along the psoas major muscle, and to separate the kidney and the perirenal fat capsule along the lateral retroperitoneum. Fixed removal of kidney cancer specimens. During this operation, in order to avoid unnecessary trauma to the organs and cause complications and fast surgical operation, the fixed support of the kidney is particularly important. At present, there is a lack of effective kidney therapy The fixation device is usually only suspended and fixed by sutures, which is traumatic to the kidney and not easy to operate, so it is not suitable for popularization and application

Embodiment 1

[0029] A kidney fixing device in open radical nephrectomy, comprising a clamping part 1 and a control part 2, the clamping part 1 wraps and fixes the kidney under the operation of the control part 2;

[0030] The main structure of the clamping part 1 is an ellipsoid, and the ellipsoid-shaped clamping part body is divided into a mirror-symmetrical first clamping part 101 and a second clamping part 102 along the long axis direction. 101 and one side of the second clamping part 102 are longitudinally sectioned and the control part 2 is installed. The control part 2 controls the opening and closing of the clamping part 1. The first clamping part 101 and the second clamping part 102 are hollowed out. Semi-ellipsoid shape, the first clamping part 101 and the second clamping part 102 are hollowed out by the transverse pipe 103 and the frame pipe 104, the inner side of the transverse pipe 103 is uniformly installed with a negative pressure suction cup 105 through a plastic tube, and th...

Embodiment 2

[0039] The use of renal fixation device in open radical nephrectomy

[0040] The kidney fixing device in the open radical nephrectomy of the present invention comprises a clamping part and a control part, and the clamping part wraps and fixes the kidney under the operation of the control part;

[0041] The clamping part is a mirror-symmetrical first clamping part and a second clamping part, and is opened and closed by the spring clamp end of the control part;

[0042] The specific operation method is as follows: control the end of the spring clip to open the first clamping part and the second clamping part, and after opening, the kidney can be wrapped. Because its structural shape is designed as a hollow ellipsoid, it can match the shape of the kidney;

[0043] After the first clamping part and the second clamping part wrap the kidneys, the negative pressure suction cups are evenly installed on the inner side of the lateral pipe through the plastic tube, which can support the ...

Embodiment 3

[0046] Application of renal fixation device in open radical nephrectomy for renal fixation in open radical nephrectomy.

[0047] Based on the descriptions of Embodiments 1 and 2, when the technical solution of the present application is applied to kidney fixation in open radical nephrectomy:

[0048] Establish an open channel according to the relevant operation of open radical nephrectomy, and fix the kidney in the clamping part of the technical solution of the present application according to the relevant operation method of Example 2;

[0049] The specific operation is: open the first clamping part and the second clamping part by controlling the end of the spring clip, and the kidney can be wrapped after opening, because its structural shape is designed as a hollow ellipsoid, which can match the shape of the kidney;

[0050] After the kidney is wrapped by the first clamping part and the second clamping part, the negative pressure suction cup is evenly installed on the inner si...

Abstract

The invention discloses the kidney fixation device in radical nephrectomy of the present invention, which facilitates the support, support and fixation of the kidney during the open kidney cancer operation. A negative pressure suction cup is installed on the inner side of the kidney to fix the kidney after suctioning the negative pressure. The fixed kidney is within the wrapping range of the clamping part. At the same time, it is stably fixed by the negative pressure suction cup. The external fixation can effectively fix the kidney, and can properly administer medicine and provide lighting from the clamping part. Its structural design is reasonable, convenient and practical, and it is suitable for popularization and application in medical institutions.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a kidney fixing device in open radical nephrectomy. Background technique [0002] In recent years, the incidence of renal cell carcinoma has gradually increased and has a tendency to become younger. With the development and wide application of imaging technology, the detection rate of asymptomatic renal cancer has also increased year by year. At present, there are reports of laparoscopic radical nephrectomy. More and more, however, most literatures still regard open radical nephrectomy as one of the preferred treatments for localized renal cancer. Compared with the transabdominal approach, the perioperative complications of the translumbar approach are significantly reduced, and it has become the main surgical approach for open radical nephrectomy. [0003] Radical nephrectomy is currently the only recognized method to cure localized renal cancer, proposed by Robson in 1...
