Medicine guiding and drainage device for hepatobiliary-pancreatic surgery chemotherapyTechnical Field
The utility model relates to the technical field of medical equipment, in particular to a medicine guiding and drainage device for surgery and chemotherapy of hepatobiliary pancreas.
Background
At present, in China, tumors become a great killer for the health of people, and in the process of treating various malignant tumors, external radiotherapy and chemotherapy are indispensable important auxiliary treatment measures. After the catheter is inserted into the target artery selectively or super-selectively, proper amount of embolic agent is injected at proper speed to occlude the target artery and cause ischemic necrosis of tumor tissue. Embolization using anti-cancer drugs or drug combination microparticles, microspheres can act as chemoembolization, called TACE (transcatheter random embolization). The operation method is to adopt the Seldinger method to perform percutaneous arteriopuncture, use a short guide wire to be placed into a catheter sheath, and then perform intubation operation under X-ray television fluoroscopy, and the steps are mainly as follows: 1. performing femoral artery puncture below the groin by using a puncture needle; 2. the puncture needle is arranged in the guide wire and withdrawn from the puncture needle; 3. placing a catheter through a guide wire, and placing the catheter into a target blood vessel under the guidance of X-ray fluoroscopy and DSA (digital radiography) radiography; 4. withdrawing the guide wire, and injecting the medicine and the embolic agent through the catheter; 5. the blood vessel of the human body is bent and the advancing direction of the guide wire is difficult to control, so that the guide wire is often required to be repeatedly adjusted to be put in place, the operation is inconvenient, and the operation time is long; in addition, when the catheter is inserted into a blood vessel, blood can enter the catheter due to the opening at the front end of the catheter, and if the rear end of the catheter is not blocked, the blood can easily flow out of the catheter.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hepatobiliary pancreas surgery is guide medicine drainage device for chemotherapy does not need to put into the seal wire earlier and pulls the pipe, can directly adopt the pipe to put into to but the advancing direction of pipe externally adjusted, it arrives the assigned position to be convenient for put into the blood vessel fast, shortens when putting into, and the unable pipe that gets into of pipe front end blood, but the liquid medicine can follow the pipe front end and flow, prevents effectively that blood from flowing from the pipe.
The above technical purpose of the present invention can be achieved by the following technical solutions:
the utility model provides a hepatobiliary pancreas surgery chemotherapy is with leading medicine drainage device, is including putting into drainage catheter and pulling magnet, the one end intercommunication of putting into drainage catheter have can by the head end traction tube that pulls magnet attraction, it is close to put into drainage catheter the one end of head end traction tube is provided with the check valve, the check valve to one side intercommunication of head end traction tube.
By adopting the technical scheme, during chemotherapy, firstly, a puncture needle is used for femoral artery puncture below the groin of a patient, the puncture needle is withdrawn after puncture, an implanted drainage catheter is rapidly implanted into a puncture hole and enters the femoral artery, then, under the guidance of X-ray fluoroscopy and DSA radiography, a traction magnet is used for drawing the advancing direction of a head end traction tube outside the body of the patient, the implanted drainage catheter is enabled to rapidly reach a designated position, then, a luer connector is used for connecting an injector to inject medicine and embolic agent, the medicine and embolic agent pass through a one-way valve to reach the designated position, and the operation of retreating the implanted drainage catheter and pressurizing and bandaging the femoral artery puncture part is completed.
The utility model discloses a further set up to: the one-way valve is composed of a plurality of triangular lobes which are annularly arranged at the opening end of the embedded drainage catheter and the tip of each triangular lobe faces the head end traction tube.
The utility model discloses a further set up to: one end of the built-in drainage catheter, which is far away from the head end traction tube, is communicated with a luer connector.
The utility model discloses a further set up to: the upper end of the traction magnet is provided with a grab handle.
The utility model discloses a further set up to: the head end traction pipe is made of iron materials.
Compared with the prior art, the utility model discloses following beneficial effect has:
firstly, the utility model is provided with a head end traction tube which can be attracted by a magnet at the front end of the catheter, after the catheter is placed into a blood vessel, the head end traction tube is attracted by a traction magnet outside the body of a patient to adjust the direction of the head end traction tube, enters the appointed blood vessel and finally quickly reaches the appointed position, a guide wire traction catheter does not need to be placed in advance, the advancing direction can be quickly adjusted, the placing time is effectively shortened, and the working efficiency is improved;
secondly, the front end of the embedded drainage catheter is provided with a one-way valve, blood can not enter the embedded drainage catheter from the one-way valve, and medicines and embolic agents can normally reach a designated position through the one-way valve, so that the chemotherapy requirements are met, and no blood flows out of the embedded drainage catheter.

fig. 2 is mainly used for showing the one-way valve placed at the front end of the drainage catheter.
In the figure: 1. placing a drainage catheter; 2. a pulling magnet; 3. a handle; 4. a head end traction tube; 5. a luer fitting; 6. a one-way valve; 61. a triangular lobe.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
In the embodiment, the medicine guiding and drainage device for surgical chemotherapy of hepatobiliary pancreas, referring to fig. 1-2, comprises an embedded drainage catheter 1 and atraction magnet 2, wherein the upper end of thetraction magnet 2 is provided with agrab handle 3; one end of the built-in drainage catheter 1 is communicated with a headend traction tube 4 which can be attracted by thetraction magnet 2, the headend traction tube 4 is made of iron materials, when the built-in drainage catheter 1 is built into a blood vessel, themagnet 2 is pulled in vitro to attract the headend traction tube 4, and the built-in drainage catheter 1 is guided to advance. Put into drainage catheter 1 and keep away from the one end intercommunication of headend traction tube 4 and have aluer 5, put into drainage catheter 1 and be close to the one end of headend traction tube 4 and be provided with a check valve 6, check valve 6 is by three in putting into drainage catheter 1 open end and be the annular setting and most advanced towards thetriangle lobe 61 of headend traction tube 4 and constitute, check valve 6 communicates to one side of headend traction tube 4.
The use method comprises the following steps: during chemotherapy, firstly, a puncture needle is used for femoral artery puncture below a groin of a patient, the puncture needle is withdrawn after puncture, the inserted drainage catheter 1 is quickly inserted into a puncture hole and enters a femoral artery, then under the guidance of X-ray fluoroscopy and DSA radiography, thetraction magnet 2 is used for drawing the advancing direction of the headend traction tube 4 outside the body of the patient, the inserted drainage catheter 1 is quickly reached to a designated position, then theluer connector 5 is used for connecting an injector to inject medicine and embolic agent, the medicine and embolic agent pass through the one-way valve 6 to reach the designated position, and the operation of retreating the inserted drainage catheter 1 and pressurizing and bandaging the femoral artery puncture part is completed.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
