Description

Arc supporting laryngoscope operating theater instruments

Technical field

This utility model relates to a kind of laryngoscope instrument, refers in particular to a kind of arc supporting laryngoscope operating theater instruments.

Background technology

Voice disorder has very high sickness rate in the crowd, the people of different sexes all can suffer from each age group.

Polyp of vocal cord is a kind of common vocal cords benign proliferative lesion in voice disorder, is commonly encountered diseases and the frequently-occurring disease of otorhinolaryngology, and sickness rate is ascendant trend year by year.The polyp of vocal cord pathological changes relates to vocal cords mucosal epithelium layer and shallow lamina propria, is more common in occupation with sound or with the excessive people of sound, shows as hoarseness.Along with growth in the living standard, people are more and more higher to the requirement meeting of social interactions and voice quality, therefore all should come into one's own to this class prevention and treatment of diseases.

The treatment of polyp of vocal cord is generally adopted Laryngoscope surgery take operation as main.The Laryngoscope surgery that often uses at present mainly contains following several:

Indirect laryngoscopic surgery: during operation, the hand-held laryngeal mirror of operation technique person one, another hand-held laryngeal forceps carries out operation technique, and its principle is only to utilize the light direct reflection, glottis is emerging in minute surface, perform the operation for the operation technique person, its shortcoming is that the visual field of direct reflection is little, and is not fogging clear, the lateral inversion of direct reflection, all make operation technique owe careful, easy residual disease tissue or damage normal structure are so use hardly at present this operation;

Fiberoptic laryngoscope operation: during operation, flexible pipe fiberoptic laryngoscope with 6-8mm exposes glottis, the 2mm passage that possesses by himself inserts the fiber biopsy forceps and performs the operation, although the patient is painful little, be easy to cooperation, but because the fiber biopsy forceps is more tiny, excision strength a little less than, therefore be difficult to excise wide base, matter firmly or larger pathological changes; This operation is only applicable to the topical anesthesia patient, and the general anesthesia operation patient higher at ask for something hits exactly the space owing to there being anesthetic intubate to take glottis with it, can't expose glottis with this operation; In addition, in this operation, the operation technique person all can only one-handed performance, has affected the curative effect of operation, therefore not adopted by the doctor.

The supporting laryngoscope operation: this is the operation of carrying out the polyp of vocal cord excision under a kind of surgical microscope supporting laryngoscope, is the traditional surgical approaches of using till today.The supporting laryngoscope that uses in operation comprises the laryngeal forceps 30 that laryngoscope 10 as shown in Figure 1a reaches as shown in Figure 3.Wherein the structure of laryngoscope 10 is referring to Fig. 1 a-Fig. 1 c, it is by handle 11 and the straight tube chamber 12 that is connected with handle 11 right angles, the upper end of handle 11 is connected with supporting bracket (not shown), and the centre in straight tube chamber 12 is cavity 121, is the steel direct laryngoscope in the middle of the front end in straight tube chamber 12; Wherein the structure of laryngeal forceps 30 is referring to Fig. 3, it is by clamp handle 31, the caliper 32 that is connected with clamp handle 31 and pincers scissors 33 compositions that are placed in caliper 32 front ends, wherein clamp scissors 33 various sizes and shape (pliers and scissors that number of different types are arranged in existing product are arranged, wherein also comprise the suction pipe head), and clamp handle 31 is nearly all the same with the structure of caliper 32, and clamp handle 31 is shear shank structures, and caliper 32 is the rectilinear forms that coordinate straight tube chamber 12.During operation, the patient need lie low, and shoulder pad on rear back mat, make mouth, pharynx, throat on same straight line, the front end in straight tube chamber 12 could be inserted throat, then, select as required the laryngeal forceps 30 with suitable pincers scissors 33,12 rear end traverses to the front end in straight tube chamber 12 from the straight tube chamber with the caliper 32 of laryngeal forceps 30, and operation is looked at straight in fixed position and the vocal cords that expose.Praised highly because having liberated both hands during this supporting laryngoscope operation, its shortcoming is that laryngoscope is without amplification, polyp of vocal cord to some more complicated is difficult to pick out extent of disease, easily excision too much, damage musculus vocalis and cause the postoperative glottic insufficiency, increase the weight of the hoarseness symptom, perhaps extract not thorough, make basilar part residual, easily recurrence.Therefore, all adding in supporting laryngoscope has at present used operating microscope to operate, as shown in Fig. 1 b, microscope 13 positions are to make the cavity 121 direct-view affected parts of its camera lens by in straight tube chamber 12, therefore the expense of operating theater instruments increases greatly, simultaneously because the operating distance that microscope requires is far away, and is subject to the size of straight tube chamber 12 cavities 121 of laryngoscope, the laryngeal forceps 30 that this outer operation is used has taken again the segment space in cavity 121, and therefore operation and exposure are still not ideal enough; And obtain complete glottis exposure for asking with it at some patients were, the operator inserted as far as possible and tightened supporting laryngoscope when being everlasting the placement supporting laryngoscope bracing frame makes exposure maximize, but tend to throat is produced corresponding crush injury, make simultaneously vocal cords tension force become large.And the vocal cords edge tension of Patients with Vocal Cord Polyp is when excessive and be unfavorable for operation.In addition, there is the neck tubbiness in some patients, the curling lodging of epiglottis, cervical vertebra occur change, hyperosteogeny bent, degree can't be crossed and face upward, denture prolapse, the more high situation of larynx body, cause supporting laryngoscope to insert and expose the glottis difficulty, thereby can not complete operation or operating time can not extend at all.There is research to find that the required special body position " neck hyperextension position " of direct laryngoscope surgery of polyp of vocal cord can cause intraocular pressure (IOP) to raise, obviously raise during neck hyperextension position 5min, prolongation along with neck hyperextension bit time, IOP rises gradually, the lOP that raises makes the Zinn's artery pressurized, cause a perfusion pressure to reduce, the danger that central retinal artery occlusion histological type inpairment of vision occurs is arranged.But the lOP that raises also vagus nerve stimulation causes heart block generation bradycardia, thereby increases the danger of operation.Simultaneously because the compressing of direct laryngoscope all can be to patient's palatine arches, tonsil, front tooth and the root of the tongue produce dampens, serious meeting causes bleeding, infection, odontoseisis come off, thereby lingual nerve injury is numb in occuring after surgery mouthful, and the tongue sense of taste disappears and feels to go down, the complication such as tongue moving obstacle.Because the voice surgery should be followed following principle: fully expose under lesion region, mirror operation, strict protection normal structure structure and recover to greatest extent, keep the vocal cords function.But the traditional supporting laryngoscope that uses at present requires mouth, pharynx, larynx sight alignment, uses the steel direct laryngoscope of straight tube chamber to expose glottis.Therefore little at some mouth openings, patient's direct laryngoscope with it that neck is short, fat, Geriatric Cervical Vertebra Disease patient, incidence stretch after can not be excessively still exists and exposes the glottis hard problem, simultaneously the steel tube wall tends to front tooth, the root of the tongue, tonsil, palatoglossal arch and cervical vertebra are produced certain contusion and impact, serious produces corresponding complication.In a word, present direct laryngoscope is not optimal operation tool when completing operation on larynx.
