Abdominal cavity forceps capable of performing flushing suction and quick replacement of catheter

Abstract

The invention relates to a pair of abdominal cavity forceps capable of performing flushing suction and quick replacement of a catheter. The pair of abdominal cavity forceps is mainly suitable for abdominal operation of a human body. The pair of abdominal cavity forceps includes a clamping mechanism and a flushing suction mechanism. The clamping mechanism includes a forceps head, a push rod, a rotating shaft, a hanging spring and a trigger. The trigger has an automatic returning function. The flushing suction mechanism includes a sliding switch, a catheter, a flushing valve, a negative pressuresuction valve and a guiding tube connector. The sliding switch has effects of clamping and pushing the catheter. The pair of abdominal cavity forceps is reasonable and compact in structural design, tissue flushing and waste liquid suction functions are integrated into the pair of abdominal cavity forceps, not only is the operation time saved, but also the disposable catheter can be quickly replaced, unnecessary surgical infection is avoided, and the pair of abdominal cavity forceps is convenient and reliable to use and low in overall cost.

Description

technical field [0001] The invention relates to a medical device, in particular to an abdominal forceps suitable for operations such as stripping, clamping, flushing and suction in human abdominal surgery. Background technique [0002] The traditional abdominal surgical forceps include interconnected forceps rod and handle assembly, the forceps rod includes an inner pull rod, a forceps sheath and a forceps core, the inner pull rod and the forceps core are respectively connected with the forceps sheath, the handle assembly includes a handle and a shaft and The rotating mechanism can be rotatably adjusted. During the operation, the operator controls the rotation of the handle to open and close the forceps to realize the functions of peeling and clamping. However, the whole operation is often accompanied by frequent tissue flushing and waste fluid aspiration, so doctors need to switch back and forth between flushing instruments, suction instruments and abdominal forceps durin...

AI Technical Summary

Problems solved by technology

However, the whole operation is often accompanied by frequent tissue flushing and waste fluid aspiration, so doctors need to switch back and forth between flushing instruments, suction instruments and abdominal forceps during the operation, and the switching of medical instruments makes cooperation difficult Increase, the replacement of instruments will also waste a certain amount of time; more importantly, there is a certain chance that the irrigation fluid will not be sucked immediately and flow to non-surgical parts, causing tissue infection; what is more troublesome is that in minimally invasive surgery, frequent instrument replacement It will bring great inconvenience to the operation

[0003] Chinese Patent No. 2011100865671 discloses an invention patent named "built-in suction device 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 clamp the suction head with forceps to absorb the bleeding and exudate, so it is difficult for the doctor to do Rapid flushing and rapid suction, which may cause bleeding and exudate suction not timely and infect non-surgical parts

But there are also obvious disadvantages: frequent replacement of the flushing suction device during the operation is a waste of time and there is a risk of infection
