Abstract
The utility model belongs to medical apparatus and instruments, and particularly relates to a three-dimensional positioning sighting device for orthopedic operations. The sighting device comprises an arc-shaped arm, a support, a positioning sleeve, a target guide needle sleeve, a positioning needle and a target guide needle. The sighting device is characterized in that the arc-shaped arm is fixed with the support through screws. Scales used for indicating angles are formed on the arc-shaped arm. A slidable arc-shaped sliding block is arranged on the arc-shaped arm, and the arc-shaped arm can carry out fixing on the arc-shaped sliding block through an arc-shaped sliding block nut. The telescopic positioning sleeve is arranged in the arc-shaped sliding block, and the positioning needle is arranged in the positioning sleeve which is locked through a positioning sleeve nut. An angle steering sliding block is connected on the support, the target guide needle sleeve is arranged in the angle steering sliding block, and the target guide needle is arranged in the target guide needle sleeve. When a doctor is in an operation, the doctor can select an anatomic landmark, which is relatively easy to confirm, in the vicinity of a target position as a positioning reference point, carries out locking on the angle steering sliding block, the arc-shaped sliding block and the positioning sleeve locking nuts according to the three-dimensional anatomic distance between the reference point and the target guide needle, then uses the three-dimensional positioning sighting device to carry out positioning and inject the target guide needle. The three-dimensional positioning sighting device has the advantages of being simple, convenient, minimally invasive, safe, and simple in structure.
Description
Technical field
This utility model belongs to medical mechanical domain, specifically is a kind of bone surgery three-dimensional localization sight.
Background technology
Orthopaedics has a lot of position fracture (as fracture of the femoral condyle, fracture of the tibial plateau, fracture of acetabulum, fracture of scapula, fracture of talus, fracture of femoral neck) when the treatment of operation nailing, owing to have a lot of important vessel nerves or articular surface not to damage on every side, need accurately put nail, and nailing repeatedly.Sight such as the forward and backward ligamentaum cruciatum sight of knee joint that present bone surgery is used, the ankle joint sight, the fracture of acetabulum sight, intramedullary pin sight etc. all is that the aiming of monoplane is fixed, with reference to anchor point and aiming point on same plane, aiming side sleeve is generally all scalable, and often fixes immutable for the length of the parts of locating a side; When operative treatments such as fracture of acetabulum, fracture of the tibial plateau, fracture of talus, Hoffa fracture, still there is not desirable, flexible three-dimensional aiming device; Though part pelvis fracture operation sight can reach three-dimensional aiming in theory, design more loaded down with trivial detailsly, reference point changes in reduction of the fracture process easily, and the sight link too much is easy to generate systematic error.
Summary of the invention
The purpose of this utility model is the problem that solves bone surgery three-dimensional localization difficulty, for the surgeon provides a kind of convenience, flexible, reduces the X line and exposes, and is fit to the bone surgery three-dimensional localization sight of minimally-invasive treatment.
The technical scheme that this utility model adopts is:
A kind of bone surgery three-dimensional localization sight, comprise that arched arm, support, angle turn to slide block, abutment sleeve, target guide pin sleeve, positioning needle, target guide pin, arched arm and support are fixed together by screw, the scale that shows angle is arranged on the arched arm, arc shaped slider is arranged on the arched arm, arc shaped slider can slide at arched arm, can fix arc shaped slider by the arc shaped slider nut, telescopic abutment sleeve is housed in the arc shaped slider, positioning needle is housed in the abutment sleeve, and abutment sleeve is locked by the abutment sleeve nut; Connection angle turns to slide block on the support, angle turns to and is provided with target guide pin sleeve in the slide block, and the target guide pin is contained in the target guide pin sleeve, and abutment sleeve and target guide pin sleeve all arrange graduation mark, three-dimensional adjustment can be carried out as requested not on same plane in the position of positioning needle and target guide pin.
Angle of the present utility model turns to and arc is set on the slide block turns to chute, and arc chute is set on the support, and both turn to chute and arc chute to link together by arc, and fix with nut.
Abutment sleeve of the present utility model arranges graduation mark, can reflect that abutment sleeve and target guide pin are in isoplanar distance; Target guide pin sleeve of the present utility model arranges graduation mark, and target guide pin sleeve can turn to slide block to rotate with angle, fixes with hold-down nut after turning to the position that needs; Arched arm of the present utility model is provided with the specification that radian varies in size, and can satisfy the replacing of different parts as required.
The bone surgery that this utility model provides turns to turning to of slide block to make positioning needle and target guide pin not on same plane with positioning needle and the target guide pin of three-dimensional localization sight by angle, produces eccentric throw.In addition, location guide pin sleeve is slidable adjustment as required, screws the abutment sleeve nut and locks, thereby reach positioning needle and the target guide pin is adjustable in the distance of other direction, finally reaches three-dimensional localization.This utility model can position from Different Plane, anchor point is selected convenient, be particularly suitable for using under the scope or in the Minimally Invasive Surgery, anchor point generally selects to expose anatomic landmark easily, squeeze into positioning needle then, carry out angle according to the 3 D anatomical distance of reference point and target guide pin and turn to slide block, arc shaped slider, the locking of abutment sleeve lock nut, the target guide pin is squeezed in sight location, applying three-dimensional location, it is safer to perform the operation, Wicresoft, reducing ray exposes, be mainly used in irregular bone (as acetabular bone, scapula, femur condyle, tibial plateau, rumpbone, calcaneus, astragalus etc.) and operative site articular surface is arranged or blood vessel is arranged, vital tissues such as nerve, the position that can't directly locate by the monoplane sight.The utlity model has easy, Wicresoft, safety, characteristic of simple structure.
