Abstract

The invention discloses a minimally invasive fluid suction scalpel, and relates to the technical field of surgery apparatuses. The minimally invasive fluid suction scalpel comprises a tool bit, a connecting rod and an operation rod. The two ends of the connecting rod are connected with the tool bit and one end of the operation rod respectively. The connecting rod and the operation rod are each ofa hollow structure and are used for sucking fluid. The tool bit comprises a main blade and a fluid suction hole. The tool bit is of a flat prism shape. The main blade is arranged on the side edge of the tool bit. The fluid suction hole is formed in the side face of the tool bit and communicated with the connecting rod to conduct fluid suction. The other end of the operation rod is connected with asucker. The defect that a scalpel and a fluid suction device used in the prior art can cause secondary traumas to a surgical spot is avoided, and the problem that an existing fluid suction scalpel can easily cause large wounds to the surgical spot and actually cannot effectively suck fluid in the surgery process is solved. The scalpel cannot cause large wounds to the surgical spot in the surgeryprocess and can effectively complete the fluid suction function when surgery is conducted on the surgical spot through the edge.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a minimally invasive liquid-absorbing scalpel. Background technique [0002] In surgery, it is often necessary to use a surgical scalpel to cut open human tissue, and then use a pipette to suck out the effusion in the surgical site. In the existing technical solutions, the functions of incision of human tissue and suction of effusion are realized by repeated entry and exit of multiple instruments into and out of the human surgical site, which causes secondary trauma to the tympanic membrane and increases surgical steps and risks. In addition, some scalpels that try to combine the function of absorbing liquid will either cause a large wound to the surgical site, which is not conducive to the later recovery and recovery; or cannot effectively combine the function of absorbing liquid with the scalpel. Contents of the invention [0003] The purpose of the present inve...
