Clinical normal disease and frequently-occurring disease during the sinunasal disease, operative treatment are one of main means that solve this type of disease.Along with the extensive use of new technique and the development of medical skill, the existing qualitative leap of nasal surgery at present, particularly microtechnique and intranasal mirror The Application of Technology, make the scope of nasal surgery progressively expand to from nasal cavity, nasal sinuses before basis cranii tissue site such as around eye socket.Just because of carrying out of this type of new operation, make original operating theater instruments can not satisfy clinician's demand, particularly when exposing the deep surgical field of view, lack effective nose dilator.Existing nasal septum dilator and nasal cavity dilator are independently, the two is not general mutually, promptly existing nasal septum dilator can not be used to expose the nasal cavity deep, and the nasal cavity dilator can't provide effective exposure to nasal septum art open country (vision scope in one's power when referring to perform the operation).In addition, existing nose dilator does not all have suction device.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can fully appear art open country, nasal cavity deep, can effectively expose nasal cavity, the nasal septum dibit dilator of nasal septum art open country again.
In order to address the above problem, nasal cavity of the present invention, nasal septum dibit dilator, mainly be formed by connecting through the pincers axle by symmetric left and right sides caliper, this caliper is divided into the pincers handle two parts at forward support arm and rear portion by the pincers axle, afterbody at this pincers handle is provided with finger-hole formula handle, and on the pincers handle before the finger-hole formula handle, be provided with the gear bracing or strutting arrangement, described support arm is an arc, the anterior of this support arm inwardly shrinks, the outwards outstanding serpentine that is in rear portion, and this support arm is bent upwards from the rear portion highlight, the leading portion that formation upwarps and the back segment of level, the planar angle in this plane, leading portion place and back segment place is α, and the size of α is 25～35 degree; Front end at described leading portion is respectively equipped with the support leaf, and this support leaf is positioned at the top of leading portion, and with the planar angle in leading portion place be β, the size of β is 90～95 degree, this end that supports leaf points to the symmetrical center line of left and right sides caliper.
After adopting technique scheme, enter nasal cavity or enter between the nasal septum mucosa of both sides by prenaris by operative incision, utilize two to support leaf and gear bracing or strutting arrangement again, can effectively expose surgical field of view, realized that a dilator can fully appear art open country, nasal cavity deep, can effectively expose the purpose of nasal septum art open country again.
As the preferred embodiment of technique scheme, on described support leaf and support arm, be provided with suction catheter, the inlet of this suction catheter is positioned at the end of described support leaf; Further, suction catheter embeds in the groove on corresponding described support leaf and support arm surface.Suction catheter can be rapidly siphons away sepage, the oozing of blood of art Yezhong under suction function, gets a clear view to guarantee deep operation art.
In the technique scheme, described gear positioning device is made of the female toothed disc of circular arc, public toothed disc and spring leaf, and wherein, an end of female toothed disc is fixed on the described right pincers handle, the other end passes from the through hole on the pincers handle of a left side, the tooth in this mother's toothed disc outside and the engagement of the tooth on the described public toothed disc; The inner of described public toothed disc is hinged on the described left side pincers handle, and should end with an end of described spring leaf against, on the other end of spring leaf was fixed on the pincers handle of a described left side, the outer end of described public toothed disc was the free end handle.The gear positioning device that adopts, sound construction, easy to operate.
In the technique scheme, described support leaf is the wicker leaf shape that end is narrow, head end is wide.
Compared with prior art, the invention has the beneficial effects as follows: the present invention can fully appear art open country, nasal cavity deep, can effectively expose art open country, nasal septum deep again; And suction catheter can siphon away sepage in the operating field and oozing of blood rapidly, has guaranteed the clear of deep operating field, and the space and the visual field of operation is provided for clinical operation.
Further the present invention is illustrated below in conjunction with drawings and Examples.
