Renal artery directional blocking device

Abstract

The invention discloses a renal artery directional blocking device comprising a clamping slot, wherein one side in the clamping slot is provided with a saccule which is connected with a gas filled tube, and a gas valve is arranged on the gas filled tube. An opening structure at the front end of the renal artery directional blocking device greatly facilitates the fixing of the blocking device around renal artery without surrounding, and the saccule can be quickly removed after the saccule is deflated, namely the blocking can be stopped in midway to temporarily restore the infusion of kidney, so as to be more beneficial to the protection for renal function. The renal artery directional blocking device is reliable in fixing after the device is fixed around the renal artery, can achieve the effect of truly blocking the renal artery, and can quickly and precisely adjust the blocking pressure on the renal artery at any time according to anatomical variations of different individuals, requirements of an operator and changes in the operation, with really reliable blocking effect. Under the condition of incomplete blocking, a patient can also take a medicine for protecting the kidney, the medicine can be directly involved in the metabolism of the kidney at the side, so as to protect the renal function according to actual situation in the operation to the greatest extent.

Description

[0001] technical field [0002] The invention belongs to the technical field of clinical medicine and surgery, and relates to a renal artery directional blocking device, which is especially suitable for laparoscopic surgery. Background technique [0003] Partial nephrectomy has developed rapidly in recent years and is mainly used in renal cancers smaller than 4 cm, solitary renal tumors, double renal cancers, benign renal tumors, segmental renal vascular malformations, and stones limited to the upper or lower poles of the kidney. The main difficulty of the operation lies in the control of renal wound bleeding and the protection of renal function. The renal artery needs to be blocked during the operation. In addition, if more renal parenchyma needs to be cut during nephrolithotomy, the renal artery also needs to be blocked. Traditional open surgery is very difficult and traumatic. In recent years, the progress of laparoscopic surgery has improved partial nephrectomy, and the ...

Problems solved by technology

The existing blocking methods are difficult to operate under laparoscopy, time-consuming, easy to slip, and even cause secondary damage

Laparoscopic renal artery occlusion and cold perfusion devices have also been proposed. The surgical operation is extremely impractical. Even if the kidney can be perfused, the operation time will be significantly prolonged and the damage to the renal artery will be increased. Once the renal artery is damaged, bleeding will be difficult. Controlled, even forced to undergo nephrectomy

In addition, the anatomical space between and around the renal artery and renal vein is extremely narrow. For anatomical variations such as premature branching of the renal artery or two renal arteries, it is necessary to separate the two renal arteries or the two branches of the renal artery during the operation. Blocking, it is also possible to block only one artery, and even
