A flushing aspirator for surgery

Abstract

The invention relates to a washing aspirator for an operation, which is mainly applicable for an enterocoelia microtrauma operation. The washing aspirator for the operation is characterized by comprising mutually matched front part and back part, wherein the front part comprises a probe, a three-way pipe, a catheter, a negative pressure suction pipe joint, a washing valve and a suction valve; the back part comprises a connector, an upper catheter, a lower catheter, an upper needle head and a lower needle head; an upper position and a lower position are arranged at one surface of the connector which is adjacent to the catheter; the catheter matches the upper and lower positions and is connected to one of the two positions; the other surface of the connector is respectively connected to the upper catheter and the lower catheter, and the upper catheter and the lower catheter are matched with the catheter; the probe, the washing valve and the suction valve are respectively connected to three end parts of the three-way pipe; and the catheter and the negative pressure suction pipe joint are fixed on the three-way pipe. The washing aspirator for the operation has a rational and compact structure design, saves operation time as the tissue washing and waste liquid suction are finished on a device, avoids unnecessary surgical infection, is convenient and reliable to use, and has low total cost.

Description

technical field [0001] The invention relates to an aspirator, in particular to a flushing aspirator for surgery, which is mainly suitable for the operation of micro-trauma in the abdominal cavity, and belongs to the medical equipment. Background technique [0002] Since in the operation, the non-stop flushing of the surgical site and the non-stop suction of waste fluid exist at the same time, this requires a flushing device and a suction device, and the two devices are constantly replaced during use. Use, it is quite troublesome to cooperate in the operation like this, and wastes operation time; During the operation, it is almost impossible to keep replacing and using like this, which brings great inconvenience to the operation. [0003] The shape and color of the flushing valve cover and the suction valve cover of the clinical flushing aspirator are the same, so there is no visual effect and hand feeling effect, making it difficult for doctors to quickly understand the use...

AI Technical Summary

Problems solved by technology

[0002] Since in the operation, the non-stop flushing of the surgical site and the non-stop suction of waste fluid exist at the same time, this requires a flushing device and a suction device, and the two devices are constantly replaced during use. Use, it is quite troublesome to cooperate in the operation like this, and wastes operation time; During the operation, it is almost impossible to replace and use it continuously, which brings great inconvenience to the operation.

[0003] The shape and color of the flushing valve cover and the suction valve cover of the clinical flushing aspirator are the same, so there is no visual effect and hand feeling effect, making it difficult for doctors to quickly understand the use of the flushing aspirator, and the doctor may forget it after a long time The position of the valve for flushing and suction is changed, which brings inconvenience to the operation

[0004] Chinese Patent No. 2012101810492 discloses an invention patent named "Surgical Aspirator with Lighting and Cleaning Function". Although it has the suction function, it can only flush the fiber optic head, but cannot flush and suction the surgical site at the same time , so it still does not overcome the above-mentioned defects in the prior art

[0005] Chinese Patent No. 2011100865671 discloses an invention patent named "Built-in Aspirator for Laparoscopic Surgery". In the abdominal cavity, in order to reduce the disadvantages caused by the replacement of instruments; so it inevitably has the following disadvantages: when using, the doctor must grasp the suction head with forceps to suck out the blood and exudate, so it is difficult for the doctor to do Rapid flushing and rapid suction may cause bleeding and exudate to infect non-surgical parts due to lack of suction
