Description

Disposable puncture device capable of avoiding effusion backflow

Technical Field

The invention relates to the technical field of medical instruments, in particular to a disposable puncture outfit capable of avoiding effusion backflow.

Background

Laparoscopic surgery is a procedure that is performed using a laparoscope and its associated instruments. The development of the laparoscopic surgery relieves the pain of the patient in operation and shortens the recovery period of the patient, and is a surgical project which develops rapidly in recent years. A disposable puncture outfit is a surgical instrument matched with a minimally invasive laparoscopic surgery. During laparoscopic surgery, a puncture outfit is needed to puncture the abdomen of a patient, thereby establishing a working channel for the surgery.

In order to facilitate medical staff to perform operations on patients, firstly, effusion in the abdominal cavity needs to be cleaned. However, when the gauze belt that will adsorb the hydrops leaves the puncture ware, the gauze can receive the extrusion of sealing washer in the puncture ware, leads to the adsorbed hydrops among the gauze to flow back to the abdominal cavity. The mode of clearing up hydrops repeatedly is inefficient and wastes operation time.

Disclosure of Invention

In order to overcome the defect that the existing disposable puncture outfit reflows when clearing accumulated liquid, the invention provides the disposable puncture outfit which can avoid the backflow of the accumulated liquid, and the defect that the accumulated liquid reflows into the abdominal cavity when the gauze belt absorbing body fluid leaves the puncture outfit is avoided, thereby improving the clearing efficiency and saving the operation time.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides a can avoid disposable puncture ware of hydrops backward flow, the puncture ware includes puncture rod, connecting piece, puncture sleeve pipe and hydrops processing apparatus, hydrops processing apparatus includes scalpel and disposable collection bag, the puncture rod passes through the connecting piece and cooperates into an organic wholely with puncture sleeve pipe, be provided with the three-way pipe on the puncture sleeve pipe, the seal membrane inlay in the right-hand member mouth department of puncture sleeve pipe's last port and three-way pipe, be equipped with the opening that is used for making puncture rod and scalpel to pass in the middle of the seal membrane, the scalpel is used for the gauze of the absorption hydrops of centre gripping, and the gauze passes through the tee bend pipeline is put into in the disposable collection bag.

Under normal conditions, the thin seam in the middle of the sealing film has little influence on the sealing effect.

Furthermore, the puncture sleeve is designed into a funnel shape, and the wall of the puncture sleeve is provided with threads with set length, so that the puncture device is convenient to stabilize in puncture.

The upper port of the puncture sleeve is a funnel opening.

Still further, the scalpel includes a longitudinal scalpel and a lateral scalpel.

The invention has the following beneficial effects: when the accumulated liquid in the abdominal cavity is cleaned, gauze full of the accumulated liquid does not need to penetrate through the sealing membrane band above the puncture outfit, but a collection bag is arranged in the middle of the puncture outfit, so that the defect that the accumulated liquid flows back into the abdominal cavity when the gauze band absorbing the accumulated liquid is separated from the puncture outfit is avoided, the accumulated liquid cleaning efficiency is improved, and the operation time is saved.

Fig. 3 is a partial sectional view of the scalpel in a state where the gauze is held, wherein the scalpel is not sectioned.

Fig. 4 is an isometric view of fig. 3.

Wherein, the puncture needle comprises 1-puncture rod, 2-connecting piece, 3-puncture cannula, 4-hydrops processing device, 5-sealing film I, 6-longitudinal scalpel, 7-gauze, 8-transverse scalpel, 9-sealing film II and 10-disposable collecting bag.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Referring to fig. 1-4, a disposable puncture outfit capable of avoiding effusion backflow comprises a puncture rod 1, a connecting piece 2, a puncture cannula 3 and an effusion treatment device 4.

The puncture rod 1 is matched with a puncture sleeve 3 through a connecting piece 2 to form a main body of the puncture outfit for surgical operation. The sealing film I5 is embedded at the funnel opening of the puncture cannula 3, and the middle of the sealing film I is provided with a slender opening, so that the puncture rod and the scalpel can conveniently pass through the opening.

The effusion treatment device comprises a longitudinal scalpel 6, a transverse scalpel 8 and a disposable collecting bag 10. After the puncture outfit is punctured into the corresponding position in the abdominal cavity, the puncture rod 1 is taken out, and the gauze 7 is clamped by the longitudinal scalpel 6 to enter the abdominal cavity to adsorb the effusion in the abdominal cavity. After the adsorption is finished, the longitudinal scalpel 6 is slowly pulled out to the corresponding position. At this time, the transverse scalpel 8 is operated to clamp the gauze 7 in the longitudinal scalpel 6, and after being slowly pulled out to the right to a corresponding position, the gauze is put into the disposable collecting bag 10.

According to the invention, the gauze full of effusion directly passes through the sealing membrane band above to be separated from the puncture outfit, but the collection bag is arranged in the middle, so that the defect that the effusion flows back to the abdominal cavity when the gauze band absorbing the effusion is separated from the puncture outfit is avoided, the effusion cleaning efficiency is improved, and the operation time is saved.
