Description

A kind of bipolar coagulation surgical scissors

Technical field

This utility model relates to a kind of shears that is used for the human body endoscopic surgery, particularly a kind of bipolar coagulation surgical scissors, and the hemostasis that is exclusively used in after the shearing of people's in-vivo tissue separates is solidified, and belongs to the medical device technology mechanical field.

Background technology

Shears is an operating theater instruments the most frequently used in the minimally invasive endoscopic surgery, through some in-vivo tissues of scissor cut, still can't stop blooding during operation, needs special-purpose apparatus to help blood coagulation, generally adopts electric coagulation forceps to stop blooding at present.Electric coagulation forceps is tissue to be heated when contacting with human body through the most advanced and sophisticated high-frequency high-voltage current that produces of active electrode, and realization is to the separation of when injected organism tissue and solidify, thereby plays the hemostatic purpose.

The electricity technology of coagulating has the single-stage electricity to coagulate and bipolar coagulation; The monopolar electrocoagulation pincers are that one pole is on binding clip in application; Other utmost points are to contact with human body; Big at surgical application medium-high frequency electric energy contact surface, can only be applied to separating and hemostasis of human body human body and large organization, high-frequency electrical energy extensively contacts human body human heart is had certain influence.Bipolar coagulation is to body tissue high-frequency electrical energy to be provided through two bipolar tips, makes the tissue dewatering between the bipolar two ends and solidifies, and reaches the hemostatic purpose; Its sphere of action is only limited between the electrode two ends; Degree of injury and coverage to body tissue want much little more than the one pole mode; Be applicable to the cutting of histoorgan separation, incision, small-sized organ etc., bipolar coagulation is used for comparatively meticulous operations such as department of cerebral surgery, microsurgery, ENT dept., department of obstetrics and gynecology and hands surgery more.

Electricity coagulates, cutting technique is applied on the medical skill, is a kind of electrosurgery method that mechanical scalpel is organized cutting that replaces.In the prior art, electricity coagulates and general separately two steps of cutting carry out, respectively by scissors and electric coagulation forceps operation.The frequent change operation tool has brought inconvenience to the doctor like this, has prolonged operating time, has satisfied not ideal surgical effect.The human body operation needs shears, must stop blooding with shears, while the hemostasis optimum efficiency is to shear blood coagulation.

Chinese patent, the patent No. 200620103179.4 has proposed a kind of double-pole electric coagulation forceps, and the bipolar coagulation technical application in operation, but has also only been played the electric coagulation hemostasis effect, still needs other operating theater instruments during cutting, changes inconvenient during operation.

Chinese patent, the patent No. 200920112865.1 has proposed a kind of electricity that is used for the human body face-lifting and has coagulated scissors straight, and the scope of effect is a subcutis, inapplicable endoscopic surgery, and also scissors bit is on-insulated, can accidentally injure its histoorgan during use.
