Description
Technical field
The utility model belongs to medical instruments field, more particularly to resets the ring spoon used through visual anesthesia articulatio cricoary tenoidea and close
Save reduction forceps.
Background technique
Articulatio cricoary tenoidea is that arytenoid is connect with the plane articulation that annular cartilage is formed in cavum laryngis, supports the movement of vocal cords.
For arytenoid on lamina of cricoid cartilage other than having the sliding of front and back, preceding outside to rear inside, there are also inclined across rotation to from inside to outside
Rotation is made, and opening and the closing function of glottis is executed, to realize the sounding of larynx, swallow protection and respiratory function.Articulatio cricoary tenoidea
Dislocation is mostly since throat's wound causes, including trachea cannula damage and throat's contusion injuries, wherein iatrogenic trachea cannula causer
It is most common.Mainly cause the reactions such as patient's sound is hoarse, swallow pain, cough of choking, seriously affects patients ' life quality, also will cause
Medical tangle hidden danger, often needs positive treatment.Articulatio cricoary tenoidea reset is main treatment method, but dedicated, reliable due to lacking
Reduction instrument, the repositioning method of clinical use is varied, and reset effect is mostly inaccurate, thus can not form unified standard
, reliable repositioning method.Due to lacking special equipment, doctor generally selects larynx section foreign body forceps, stirs steel bar, even fiber larynx
Mirror, direct laryngoscope etc. are used for stirring for the arytenoid of Dislocation of cricoarytenoid joint, are unable to reach thoroughly clamping arytenoid, realize true
Positive embolia operation.And these operations can only carry out under local anaesthesia mostly, and patient has Nausea and vomiting reaction, pain
Greatly, therefore fitness is poor.There is application to arrive the articulatio cricoary tenoidea reduction forceps of patent, but design structure is still the doctor of patient's end sitting position
Operation, and a degree of can only stir arytenoid, all with common foreign body forceps, stir steel bar etc. without essential distinction, because
This, doctor is selected to use less.

Specific embodiment
With reference to the accompanying drawing and with specific embodiment, the utility model is furtherd elucidate.It should be understood that these embodiments are only used
In illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, this field skill
Art personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
Articulatio cricoary tenoidea is the flexible multiaxis synovial joint of an activity, and forms of motion is extremely complex.In vocal cord movement process
In, no matter vocal fold adduction or outreach, it is not only that swing, sliding and the rotational action of arytenoid, which all link up, synchronously complete,
It is vertical, successively occur.So Dislocation of cricoarytenoid joint is typically also multiaxis, complicated dislocation when occurring, it is not single direction
Dislocation.In addition, articulatio cricoary tenoidea face is small, glenoid is shallow, and position cannot achieve deeply and accurately handle touch reset.
As shown in figures 1-4, the special reduction forceps of the application can effectively, to be held fixedly the irregular spoon shape of form soft
Bone, to be able to achieve precisely smoothly translation, rotational action.It mainly include upper vice body and lower vice body, wherein lower vice body is to fix
Portion, upper vice body are movable part；The two is for flat pattern, and periphery places insertion bottleneck throat using cambered surface and damages software group
It knits.Wherein upper vice body includes clamp handle, linkage section and clamp section, and the linkage section includes Ligation in vitro section and internal linkage section, institute
Stating linkage section in Ligation in vitro section opposite bank, there is bending angle clamp handle to be made to be located at downward, the clamp handle and Ligation in vitro section
Tail end is hinged, and the clamp section and the front end of internal linkage section are hinged, and the internal linkage section is equipped with close to one end of clamp section
Section is upwarped, and clamp section is leftward or rightward bending with respect to the plane where linkage section.The lower vice body is integrally formed
Design, and there is clamp handle compatible with upper vice body, linkage section and clamp section；The upper vice body and lower vice body pass through hinged block group
At four-bar mechanism, enables and upper vice body is driven to translate the clamp section for making upper vice body and lower pincers along lower vice body when stepping up clamp handle
The clamp section of body forms folding.In order to make upper vice body along the smooth translation of lower vice body, the bending part of the linkage section of vice body everywhere is used
Arc-shaped transition connection.
In addition slide block assembly is set between the upper vice body and the linkage section of lower vice body, including is located at vice body linkage section
Sliding block, be located at lower vice body and empty window corresponding with upper vice body slide position, the sliding block are fastened in sky window, and can be along empty window
Limit sliding.
It is further improved, clamp section is made of the binding clip of bending section and front end, and bending section is to left or right with 30 ° or so
The binding clip of horizontal arc curvature, front end is cyclic annular using snakehead, and the smooth flank of tooth is arranged on opposite folding face.Due to adopting
With the cricoid binding clip of snakehead, when stepping up cartilaginous tissue, soft tissue can be packed in ring center hole can more effectively clamp it is soft
Bone tissue, while firm grip degree is improved by the flank of tooth of smooth arc-shaped surface, it improves and resets efficiency.
Preferably, the bending angle between the Ligation in vitro section and internal linkage section is 110~135 °.The clamp section
The horizontal curvature angle of opposite linkage section is 25~35 °.The angle for upwarping linkage section in section opposite bank is 120~160 °.
The Ligation in vitro segment length is 2~4cm, and the internal connection segment length is 8~12cm, it is described upwarp segment length for 1~
2cm, the clamp segment length are 3~5cm.
Existing articulatio cricoary tenoidea resets the excessively other surgical clamps of multi-pass and is used instead, these surgical clamp ends are in smooth
Plane, coincideing with the arytenoid face of irregular shape, property is poor, these surgical clamps are when stirring to unstable, the hand of arytenoid force
Art, which clamps, to be easy to slip between end and arytenoid, seriously affects reset effect, and articulatio cricoary tenoidea surface mucous is be easy to cause to damage.
The object of the present invention is to provide a kind of more identical with arytenoid contact surface, contact is more stable, and articulatio cricoary tenoidea reset effect is more
Good, the articulatio cricoary tenoidea reset used time is shorter, and the articulatio cricoary tenoidea of damage will not be caused to stir pincers to articulatio cricoary tenoidea.
Flat reduction forceps of the invention, can effectively, be held fixedly the irregular arytenoid of form, to be able to achieve
Precisely smoothly translation, rotational action.Whole body material selection alloy material, matter is unlikely to deform firmly, long-lasting use, and surface is using dark
Line design, will not generate reflective, influence surgical field of view.
