Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the subcutaneous curved separation bar that especially direct oral cavity vestibule device for endoscopic thyroid surgery is used.
Background technology
Because its splendid cosmetic result, wound be little etc., advantage is subject to patient's favor to direct oral cavity vestibule device for endoscopic thyroid surgery deeply, need be to the subcutaneous blunt separation that carries out in lower jaw position when direct oral cavity vestibule device for endoscopic thyroid surgery, so that the trocar (Trocar) can enter operative space smoothly, make chamber mirror and handling tongs there is enough initial subcutaneous spaces for start to manufacture enough operative spaces under the good visual field, reduce the risk that blindly separates bring hemorrhage, lacks unity and coherence.Separate lower jaw and cervical region is subcutaneous need to cross mandibular bone by vestibule of mouth, current operating theater instruments used all can not meet separation needs, therefore needs to research and develop a kind of special separation bar.
Utility model content
For the technical problem existing in prior art, the purpose of this utility model is: provide one can cross mandibular bone, to lower jaw and the subcutaneous curved separation bar of carrying out blunt separation of cervical region.
The purpose of this utility model is achieved through the following technical solutions: the subcutaneous curved separation bar that a kind of direct oral cavity vestibule device for endoscopic thyroid surgery is used, comprise handle and separation bar body, handle and separation bar body are fixedly connected, the leading portion of separation bar body is spindle thick between the detail of two, the width at spindle middle part is greater than thickness, on described separation bar body, have arc connecting portion, described spindle is directly extended with changeover portion, and described changeover portion is connected with arc connecting portion.
As a kind of preferred version, the length sum of described spindle and arc connecting portion is 5-12cm, and the angle between spindle axis and separation bar body back segment is 135 °-165 °.
As a kind of preferred version, described handle is prism-shaped, transverse cross-sectional profile and is petal or transverse cross-sectional profile and is oblate.
As a kind of preferred version, described handle width is 2-5cm.
As a kind of preferred version, described handle and separation bar body are made by rustless steel.
As a kind of preferred version, the width at described spindle middle part is 1.2-1.8 times of thickness.
As a kind of preferred version, the Breadth Maximum of described spindle is 0.6-2cm, and spindle length is 1-3cm.
As a kind of preferred version, separation bar body back segment is cylinder, and diameter is 0.3-1.5cm, and cylinder length is 10-30cm; Decreased food is 5-10cm.
As a kind of preferred version, described transition section length is 1-5cm.
Work process of the present utility model: separation bar enters the dark face of platysma from vestibule of mouth median incision, is first separated to suprasternal fossa downwards, notes wanting a direction one to disclose on earth, avoids repeated puncture to cause puncture aspect inconsistent; Then separate the dark face of platysma with lower jaw intersection toward cervical region, make chamber mirror and the both sides trocar (Trocar) enter smoothly operative space to perform the operation to manufacture enough spaces.
This utility model has following advantage and effect with respect to prior art:
1, subcutaneous curved separation bar of the present utility model can be crossed mandibular bone, to lower jaw and the subcutaneous blunt separation that carries out of cervical region, enough initial subcutaneous spaces are provided, and the trocar (Trocar), chamber mirror and handling tongs can start the manufacture of operative space after can entering smoothly operative space under the good visual field.
2, the handle of subcutaneous curved separation bar of the present utility model is arranged to be prism-shaped, transverse cross-sectional profile and is petal or transverse cross-sectional profile and is oblate, prevents that direction from changing because of slip; Handle width is arranged to 2-5cm, is easy to grip.
3, handle and separation bar body are made by rustless steel, while avoiding using, use different sterilization methods because material is different, facilitate use, adopt rustless steel to make the curved separation bar of this utility model there is certain weight simultaneously, make patient have better feel and can better accurately controlling, avoid because of weight kick the beam be difficult to control cause puncturing excessive or too small.
