Description

Bile duct puncture irrigator for laparoscopic surgery

Technical Field

The utility model relates to an apparatus for laparoscopic surgery especially relates to a bile duct puncture flusher for laparoscopic surgery.

Background

With the progress of minimally invasive techniques and instruments, the method for treating the intrabiliary obstruction and the external pressure obstruction by percutaneous liver puncture bile duct drainage diagnosis and treatment of obstructive jaundice is widely used clinically. In the puncture operation, need use the peritoneoscope puncture ware to puncture patient's belly and reach bile duct department, penetrate the pjncture needle through the inside bile duct that penetrates of peritoneoscope puncture ware, the piston rod of pulling connection at pjncture needle rear end syringe extracts bile duct inner bag juice and gets into the syringe to confirm that the pjncture needle inserts the bile duct completely, current pjncture needle is a longer steel needle, and the pjncture needle can only be pricked the needle along peritoneoscope puncture ware direction, because of the bile duct position with move towards different, lead to the pjncture needle to prick the needle inaccurate, prick. After the puncture operation, the puncture needle needs to be pulled out of the laparoscope puncture device, the flushing pipe connected with the saline bag is inserted into the bile duct again through the laparoscope to flush the bile duct, the preparation operation time for the flushing pipe to be connected with the saline bag and inserted into the bile duct again through the laparoscope puncture device is long, and the flushing waiting time is long. And gaps are formed between the puncture needle and the flushing pipe and the inner wall of the laparoscope puncture outfit, so that gas inside and outside the abdomen of a patient is exchanged during puncture and flushing operation, so that intra-abdominal decompression or infection of the patient is caused, and the operation risk is high.

Disclosure of Invention

The utility model provides a solve above-mentioned technical problem, provide a bile duct puncture flusher for laparoscopic surgery, puncture needle direction is adjustable, the pjncture needle can accurately prick the bile duct of different positions and trend, needle operation labour saving and time saving, and puncture operation and flushing operation share a hose, this hose of salt water bag can be connected in advance before the operation, shorten and wash latency, and set up the sealing washer at this hose pipe wall, avoid the inside and outside gas exchange of patient's belly, reduce the operation risk.

The technical solution of the utility model is that:

bile duct puncture flusher for laparoscopic surgery includes the pjncture needle, and its special character lies in: the rear end of the puncture needle is detachably connected with a transparent hose, a sealing ring arranged along the axial direction is arranged on the rear side of the wall of the hose, the rear end of the hose is connected with a three-way two-position reversing valve, a first joint of the three-way two-position reversing valve is connected with the hose, a second joint of the three-way two-position reversing valve is connected with an exhaust joint, and a third joint of the three-way two-position reversing valve is connected with a flushing joint.

The utility model has the advantages that:

1. because the hose connected at the rear end of the puncture needle passes the puncture needle completely through the laparoscope puncture outfit, the puncture needle is in a free state, a doctor can quickly and accurately puncture the puncture needle into bile ducts with different positions and trends by using forceps on two sides in the abdomen of a patient, the puncture operation is time-saving and labor-saving, the hose is transparent, a syringe connected with the hose only needs to extract a small amount of bile, and the doctor can watch the bile in the hose to judge whether the puncture needle is inserted into the bile duct.

2. The three-way two-position reversing valve is connected to the rear end of the hose, the second joint of the three-way two-position reversing valve is connected with the exhaust joint, the third joint of the three-way two-position reversing valve is connected with the flushing joint, the syringe and the saline bag are sequentially connected with the second joint and the third joint before operation, and the three-way two-position reversing valve is used for communicating the hose with the syringe or the saline bag through reversing, so that the flushing waiting time is greatly shortened.

3. Because the sealing ring is arranged on the wall of the hose and arranged along the axial direction, the hose and the laparoscope puncture outfit are sealed, the gas exchange inside and outside the abdomen of a patient is avoided, and the operation risk is reduced.
