But, in open thyroidectomy, during this ultrasonic surgical blade work, the local temperature of its dynamic cutter head can reach 50 ~ 100 DEG C, to the vital tissue around thyroid gland and structure as recurrent nerve, superior laryngeal nerve, parathyroid gland and tracheae, neck vagina vasorum etc. easily produce fire damage so that generating portion or irreversible damage, degree of its damage along with ultrasonic surgical blade and these tissues, structure spacing reduce and the working time prolongation and progressively increase the weight of, solidifying liquid heat of cutting place conducts also possible injured nerve simultaneously.Therefore, in the urgent need to improving this kind of ultrasonic surgical blade, the fire damage rate produced when reducing its work, thus surrounding normal during ultrasonic cutter head work and even important organizing are protected.
Utility model content
Problem to be solved in the utility model is to provide a kind of ultrasonic surgical blade; adopt this ultrasonic surgical blade to carry out operation, particularly open thyroidectomy, the heat transfer of cutter head can be reduced; thus the tissue of human body, structure and nerve are protected, make them not easily produce damage.
For solving the problem, take following technical scheme:
Ultrasonic surgical blade of the present utility model comprises in scissors-like handle, and there is cutter head the front end of handle, tail end has finger ring.Described cutter head is divided into stationary knife head and dynamic cutter head, and the two coordinates in bending in the same way.Described dynamic cutter head is made up of metal material, and has the conduit that can be connected with supersonic generator in the handle unit of its correspondence.Described stationary knife head has the plastic support plate for support dynamic cutter head, plastic support plate has deep-slotted chip breaker, the shape of this deep-slotted chip breaker and dynamic cutter head matches, and when two cutter heads are closed, the Lower Half of dynamic cutter head is positioned at the deep-slotted chip breaker of stationary knife head plastic support plate completely.Be characterized in described dynamic cutter head there is the guard shield longitudinally arranged along it, between the inner surface of guard shield and dynamic cutter head, have gap.
Further improvement of the utility model scheme is that described guard shield, the length of plastic support plate and outer width are all equal, and when two cutter heads close, the lower surface of guard shield and the upper surface of plastic support plate are fitted completely.The binding face between guard shield and plastic support plate can be improved so to greatest extent, namely increase contact surface when performing the operation between cutter head position and required cut-out tissue, reduce the risk that clamp loosens, comes off.
Take such scheme, have the following advantages:
Owing to the dynamic cutter head be made of metal of ultrasonic surgical blade of the present utility model there being the guard shield longitudinally arranged along it, gap is had between the inner surface of this guard shield and dynamic cutter head, therefore when the supersonic frequency this dynamic cutter head being applied to 55.5kHz makes it carry out mechanical oscillation, the localized hyperthermia of dynamic cutter head can be blocked in this guard shield completely, make it not easily spread, thus dynamic cutter head can be reduced in art to the damage of tissue, structure and nerve.Report that ultrasonic surgical blade can cause the temporary paralysis of recurrent nerve apart within recurrent nerve 3mm, suggestion distance more than recurrent nerve 5mm, now patient also may abandon ultrasound knife for the sake of security and adopt traditional modus operandi, and adopts ultrasonic surgical blade of the present utility model that so-called ultrasound knife forbidden zone can be made to become less.In addition, when utilizing ultrasonic surgical blade clamp bulk tissue, the tissue in distally easily when cutting off not yet fully because clamp is more loose or hand shaking causes coming off, hemorrhage, and the guard shield in ultrasonic surgical blade of the present utility model on dynamic cutter head can increase contact surface when cutter head and required cut-out are organized in clamp, thus clamp can be reduced come off, organize hemorrhage risk.
