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 fixation 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 body structure of the clamping part 1 is ellipsoidal, and the main body of the ellipsoidal clamping part is divided into a mirror-symmetrical first clamping part 101 and a second clamping part 102 along the long axis direction, and in the first clamping part 101 and one side of the second clamping part 102 are longitudinally cut and installed with the control part 2, the control part 2 controls the opening and closing of the clamping part 1, and the first clamping part 101 and the second clamping part 102 are hollowed out Semi-ellipsoid, the first clamping part 101 and the second clamping part 102 form a hollow shape through the transverse pipe 103 and the frame pipe 104, and the inner side of the transverse pipe 103 is uniformly installed with a negative pressu...

Embodiment 2

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

[0040] The kidney fixation device in open radical nephrectomy of the present invention includes 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 the first clamping part and the second clamping part with mirror image symmetry, and the opening and closing are realized by the spring clip end of the control part;

[0042] The specific operation method is: control the end of the spring clip to open the first clamping part and the second clamping part. 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 kidney is wrapped by the first clamping part and the second clamping part, the negative pressure suction cup is evenly installed on the inner side of the transverse channel through the plastic tube t...

Embodiment 3

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

[0047] Based on the description of Examples 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 side of the transverse channel t...

Abstract

The present invention discloses a kidney fixing device for an open radical nephrectomy. By using the kidney fixing device, it is convenient to support, bear and fix kidneys during open renal cancer surgery. The kidneys are wrapped by a clamping part under the operation of a control part, meanwhile, the inner side of the clamping part is provided with a negative-pressure sucking disc by which the kidneys are fixed after negative pressure is sucked, the fixed kidneys are wholly located within a wrapping range of the clamping part, and meanwhile, the fixed kidneys are stabilized and fixed by using the negative-pressure sucking disc and are fixed at the outer part due to the cooperation of the control part and a traction device, so that the kidneys may be effectively fixed, and administrationmay be appropriately performed at the clamping part which may also provide illumination. The kidney fixing device is reasonable in structural design, convenient, practical and 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 fixation device in open radical nephrectomy. Background technique [0002] In recent years, the incidence of renal cell carcinoma has gradually increased and tends to be younger. With the development and wide application of imaging examination technology, the detection rate of asymptomatic renal cell carcinoma is also increasing year by year. At present, the report of laparoscopic radical nephrectomy More and more, but most of the literature still regards open radical nephrectomy as one of the first-choice treatments for localized renal cell carcinoma. Compared with the transabdominal approach, the perioperative complications of the translumbar approach are significantly reduced, and it has become the main surgical approach for radical radical resection of open kidney cancer. [0003] Radical nephrectomy is currently the only recognized method that may cure loca...
