Description

Surgery electrode assembly

Technical field

This disclosure relates to a kind of hemostasis tool of surgical operation, especially a kind of surgery electrode assembly.

Background technique

Currently, medical instrument fining, specialization are a target and trend.Coagulation efficiently, is reliably stopped as a kind of Blood mode, is widely used in surgical operation.Surgery is especially adapted for use in minimally invasive microsurgery, neurosurgery with electrode assembly It is used with passage aisles deep operations such as transnasal approach operations, is particularly suitable for being used cooperatively with conchoscope, ventriculoscope, be mainly used in The electric coagulation hemostasis of minimally invasive microsurgery or neurosurgery.Since the operating space of various operations is limited, and perform the operation Notch or channel are bigger, bigger to the secondary injury of patient, so operation path all makes every effort to minimum, minimally invasiveization.

Bipolar coagulation forceps of various shapes are generally used in existing surgical operation, cardinal principle is by by two panels tweezer tablet In a fixing seat, tweezer tablet is mediated by finger, so that the tip of two tweezer tablets is clamped blood vessel or tissue, to make through two tweezers The high-frequency current of piece tip passes through the local vascular or tissue clamped, and using the fuel factor of high-frequency current, makes vascular wall dehydration wrinkle Contracting, vessel inner blood solidification, and blood vessel is made mutually to combine together with blood clot, and reach effectively hemostasis purpose.Due to common bipolar The tweezer tablet of diathermy forceps is wider, structural volume is larger, into two tweezer tablets of human body before bar part spacing maximum at least 10mm or more, and And limited length, therefore be not suitable for going deep into organization internal to minimally invasive wound or from passage aisle (such as transnasal approach, ventriculoscope) Wound stop blooding, especially in minimally invasive microsurgery and neurosurgery use when have significant limitations.Furthermore it is based on Tweezer tablet enters the larger volume of human body parts and interferes to use simultaneously with other instruments.Additionally, due to the tweezer of common bipolar coagulation forceps Piece forward portion is longer, and tip easily misplaces often in engagement, influences coagulation effect and efficiency.

A kind of existing surgery with electrode assembly by the mating reactions of inner and outer tubes realize the close of eletrode tip and It is separate.
