Description
Technical field
This utility model belongs to medical device technology mechanical field, and mainly a kind of manual orthopaedics bores.
Background technology
In dynamic bone surgery, have and relate to a kind of minimally invasive spine surgical system, this system is bored by foramen intervertebrale lens, radio frequency main frame and manual orthopaedics and is formed, and especially manual orthopaedics bores, and the structure of its design can produce vital impact to whole operation.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of manual orthopaedics easy and simple to handle, that structure is simple, procedure efficiency is high to bore.
The purpose of this utility model has been come by following technical solution, comprises spiral cutting bar, spiral cutting headstock, wrench shaft and spherical spanner, and described spiral cutting headstock one end is connected with spiral cutting bar, spiral cutting bar is fixed with spiral cutting head; The spiral cutting headstock other end is connected with the endoporus phase buckle of wrench axle, and the front end shaft portion cover of this wrench axle has movable sleeve, and rear end part and the spherical spanner of this wrench axle are nested and fix.Be placed with shelves pin between the axial groove that the pin-and-hole that described movable sleeve cover arm is offered and wrench axle axial wall are offered, between the endoporus end wall of this grade of pin and wrench axle, accompany stage clip; The previous section of the axial groove offered at wrench axle axial wall is offered porose; Movable sleeve cover arm also offers inner groovy.
As preferably, the radial place of described spiral cutting headstock one end offers a circle groove, and this groove is corresponding with hole, and is built-in with steel ball.
The beneficial effects of the utility model are: have easy and simple to handle, change spiral cutting head convenient, make operative doctor in the process of having an operation, operate feature freely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is respectively: 1, spiral cutting head; 2, spiral cutting bar; 3, spiral cutting headstock; 4, movable sleeve; 5, steel ball; 6, shelves pin; 7, stage clip; 8, wrench shaft; 9, spherical spanner; 31, groove; 41, pin-and-hole; 42, inner groovy; 81, axial groove; 82, hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to this utility model: as shown in Figure 1, this utility model comprises spiral cutting bar 2, spiral cutting headstock 3, wrench shaft 8 and spherical spanner 9, described spiral cutting headstock 3 one end is connected with spiral cutting bar 2, spiral cutting bar 2 is fixed with spiral cutting 1; Spiral cutting headstock 3 other end is connected with the endoporus phase buckle of wrench axle 8, and the front end shaft portion cover of this wrench axle 8 has movable sleeve 4, and rear end part and the spherical spanner 9 of this wrench axle 8 are nested and fix.
Described movable sleeve 4 overlaps between axial groove 81 that pin-and-hole 41 that arm is offered and wrench axle 8 axial wall offer and is placed with grade pin 6, accompanies stage clip 7 between the endoporus end wall of this grade of pin 6 and wrench axle 8; The previous section of the axial groove 81 offered at wrench axle 8 axial wall offers porose 82; Overlap on arm at movable sleeve 4 and also offer inner groovy 42.
The radial place of described spiral cutting headstock 3 one end offers a circle groove 31, and this groove 31 is corresponding with hole 82, and is built-in with steel ball 5.
This utility model is when needs change spiral cutting 1, by the effect of shelves pin 6, stage clip 7 and wrench axle 8, wrench axle 8 is slided at axial groove 81, groove 31 is not corresponding with hole 82 simultaneously, and now steel ball 5 slides to the inner groovy place of movable sleeve 4, and spiral cutting headstock 3 can take out smoothly.
This utility model and foramen intervertebrale lens, radio frequency main frame support the use, and the scope of application of this foramen intervertebrale lens is: 1) viewing directional angle 30 °; 2) angle of visual field >=80 °; 3) service aisle diameter >=3.5mm; 4) external diameter≤6.5mm; 5) active length 170mm ~ 190mm.
The scope of application of radio frequency main frame is: 1) output frequency: 4.0MHz & 1.7MHz;
2) power: 120W is adjustable; Each functional energy distributes:
Cutting: ablation energy 90%, hemostasis energy 10%, peak power output: 120W;
Mix and cut: ablation energy 50%, hemostasis energy 50%, peak power output: 90W;
Hemostasis: ablation energy 10%, hemostasis energy 90%, peak power output: 60W;
Melt peak power output: 45W; Bipolar peak power output: 120W.
This utility model is not limited to above-mentioned embodiment; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within this utility model protection domain.
