technical field

The utility model relates to the technical field of medical instruments, in particular to a multifunctional tissue separating forceps.

Background technique

Minimally invasive surgery has been widely used clinically in recent years, and has been recognized by both clinicians and patients because of its small damage, less bleeding, and quick postoperative recovery. In minimally invasive surgery, separating forceps and aspirators are the most commonly used surgical instruments. The former is mainly used to clamp and separate tissues, and the latter is mainly used to absorb blood, mucus, or other obstacles that hinder the surgical line of sight, such as cavities. The smoke generated during endoscopic surgery should be avoided to prevent these substances from hindering the operation. Since both the separating forceps and the aspirator have a slender rod-like structure, it takes a long time to replace the two instruments during the operation, and the frequent switching process may easily cause discomfort to the patient and even cause unnecessary damage.

As another excellent solution, the pliers head is bent downward.

The utility model at least has the following advantages:

1. By modifying the rod body of the tissue separation pliers, the positive and negative pressure pipes connected to the inner pipe and the clean water pipe connected to the outer ring pipe can be quickly adjusted through the three-way valve switch. The access direction of the ring pipeline can provide the functions of sucking blood mucus, smoke during laparoscopic surgery, cleaning tissue, and cleaning the pipeline; the clamp rod of the inner clamp device leads from the inner tube pipeline to the inner tube of the three-way valve switch The through hole of the pipeline can make the suction and cleaning functions and the clamping use of the internal forceps device not interfere with each other;

2. Reasonably setting the relative positions of the inner tube, the outer tube and the three-way valve can make the structure of the separation forceps more streamlined, and the trumpet-shaped inner tube through-hole can ensure that the mucus is not blocked when the mucus is sucked; The through valve switch is equipped with a switch paddle, so that the outer ring pipeline and the inner tube pipeline are separated or connected at the same time, and a corresponding card position is formed between the switch paddle and the three-way valve, which is convenient for the doctor to adjust the dial under intense operations. The corresponding function of slice acquisition saves time and is suitable for intense surgical treatment process.
