Technical Field
The utility model belongs to the technical field of medical operation tools, and particularly relates to a perfusion catheter for obtaining operation from a lung.
Background
During a lung obtaining operation, pulmonary artery and pulmonary vein perfusion catheters are generally needed to be used, no special perfusion catheter exists in the market at present, the perfusion catheter is generally formed by modifying an infant trachea cannula, a vena cava drainage tube, a silica gel catheter and the like, and the perfusion catheters with different types and functions are needed to be used in the same operation due to different operation steps. 1. In the operation for obtaining the lung, the surface of the root part of the pulmonary artery is subjected to purse-string suture conventionally at present, a small opening is cut in the middle of a purse-string suture by an operation blade, the operation blade is expanded by an instrument and then is placed into a modified pulmonary artery perfusion catheter, and then the suture is tensioned by a luminal suture and is fixed with the perfusion catheter. In the operation, the surgical blade is easy to hurt the suture line when the pulmonary artery wall is cut in the middle of the purse line, so that the suture line is broken and can not be fixed, and meanwhile, the perfusion catheters are modified catheters without fixed buckles or corresponding structures for effective fixation, so that adverse consequences are caused by easy separation in the perfusion process. 2. In the operation of obtaining the lung, the lung needs to be subjected to retrograde perfusion in vitro and separated from the heart conventionally, the existing perfusion catheter is mostly formed by modifying a silica gel catheter or an infant trachea cannula, and a balloon with proper size is needed to seal a pulmonary vein opening in the retrograde perfusion process so as to prevent the perfusion liquid from overflowing. Therefore, the perfusion catheter specially used for the lung harvesting operation needs to be designed aiming at the problems.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a perfusion catheter for lung harvesting operation.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a perfusion catheter for lung acquisition surgery comprises a catheter body, a fixing buckle, an air bag, an inflation tube and an inflation connector, wherein the catheter body consists of a catheter connector, a catheter and a metal guide core, the fixing buckle and the air bag are arranged on the catheter body, the distance between the fixing buckle and the front end of the catheter body is 1.0-1.5 cm, and the air bag is arranged close to the fixing buckle; the air bag is provided with an inflation tube; the inflation tube is fixed on the outer wall of the catheter body and extends to the upper part of the catheter body; the end of the inflation tube is provided with an inflation joint.
The utility model has the innovation points that the perfusion catheter is provided with the fixing buckle and the air bag, the fixing buckle is required to effectively fix the perfusion catheter to prevent the perfusion catheter from falling out when the lung is operated to perfuse the pulmonary artery in the early stage of the operation for obtaining the lung, and the air bag on the perfusion catheter is required to seal the opening of the pulmonary vein to prevent the perfusion liquid from overflowing when the pulmonary vein is reversely perfused in the later stage, thereby realizing the function of one-tube dual-purpose.
Furthermore, the fixed buckle can be removed by being broken off, the fixed buckle does not need to be used when the pulmonary vein is perfused in the backward direction at the later stage, and the fixed buckle can be removed by being broken off by being twisted off under the action of external force.
Furthermore, the fixing buckle is provided with a wire clamping groove, the wire clamping groove is divided into 4 fifth circular wire clamping grooves and 2 fifth circular wire clamping grooves, the wire clamping grooves are convenient for binding surgical wires, and slipping is avoided.
Further, still including blocking the buckle, block the buckle setting in the middle part position of pipe body, block the buckle and can block the pipe as required and avoid the perfusate refluence.
Further, still include the side opening, the front end of pipe body be provided with the side opening, the side opening is used for the liquid in the abundant discharge pipe, avoids the poor perfusion that causes behind the catheter anterior segment adherence.
The utility model has the advantages that: 1. the detachable fixing buckle is arranged on the body of the perfusion catheter, so that a purse-string suture with high difficulty can be not needed during pulmonary artery perfusion, and only a 'clip' suture is needed to be performed on two sides, the fixing buckle is provided with a corresponding thread clamping groove, and an operation suture is fixed by the thread clamping groove on the fixing buckle, so that the operation suture is stable and firm and is not easy to drop; 2. the perfusion catheter is provided with a puncture metal guide core, can be directly punctured in the middle of the 'clip' suture and is placed into the catheter body, and can completely avoid the risk of suture fracture caused by the incision of the pulmonary artery wall by the surgical blade; 3. when the pulmonary vein retrograde perfusion is carried out, the fixing buckle can be detached through the knob, and the balloon is inflated, so that the pulmonary vein can be directly sealed and perfused without using an additional catheter, and the function of one tube with multiple purposes is realized.
