Abstract
The utility model belongs to the field of medical equipment, a restorer is rolled over to hollow sharp dentary. It is equipped with hollow sharp tooth (1, 5), and forceps holder arm (2), centre gripping handle (3), locking bolt (4), its characterized in that is with centre gripping handle (3) when pressurizeing in opposite directions, and forceps holder arm (2) are close to relatively, drive two hollow sharp tooth (1, 5) and are close to relatively and press from both sides tight bone piece, cooperate locking bolt (4) to maintain simultaneously and reset stably, and can choose for use corresponding diameter to fix the steel needle according to operation needs and pierce the steel needle through the direction guard action of hollow sharp tooth this moment. Can be applied to all kinds of steel needle tension band internal fixations of orthopedics operations, long oblique fracture reset thread a needle fixed. The integration operation of realized the reduction of the fracture among the bone surgery, fixing, thread a needle has easy operation, and the safe and reliable accuracy when fixing that resets is saved time and the manpower, improves advantages such as operation quality.
Description
Technical field
The invention belongs to medical instruments field, relate to the reduction of the fracture in bone surgery fixedly thread a needle and traction therapy of bone time assistance application.
Background technology
In bone surgery treatment, the reduction of the fracture is an important link, after multiple fracture positor clamping bone block reset conventional at present, when row steel plate is placed, places because positor stops, namely occurs resetting and lose while unclamping reduction forceps.Or clamping when electric drill is threaded a needle temporary fixed, can only enclose drill point at clamp tooth rim after resetting, on smooth and hard bone block surface, often easily slippage and direction skew can not effectively fix the situations such as bone block, and operation technique time and effort consuming, has a strong impact on surgical quality.
Summary of the invention
The present invention efficiently solves above problem, hollow pointed tooth fracture reposition instrument, it is provided with hollow pointed tooth (1,5), jaw arm (2), holding handle (3), clamping screw (4), when is characterized in that holding handle (3) pressurizes in opposite directions, jaw arm (2) is relatively close, drive two hollow pointed tooths (1,5) relatively near and clamp bone block, lock simultaneously bolt (4) can maintain reset stable.After clamping bone block, two hollow pointed tooths are linearly corresponding, can need to select corresponding thickness draw point to fix bone block through hollow pointed tooth drill point according to operation.The internal diameter of two hollow pointed tooths and folding distance are designed to the technical parameter the most often applied in bone surgery.Skid or offset direction when the guiding protective effect of hollow pointed tooth substantially eliminates drill point; other two hollow pointed tooths relatively point-blank; under guide effect; also ensureing that locking pin pierces a little and gets out is some bicuspid position, thus ensure that fixed-direction is accurate and fixing stablizing of threading a needle.Coordinate reset locking device, a people can complete aforesaid operations.The design is widely used, can be used for that Patella fracture reduction is threaded a needle, olecranal fracture reset thread a needle, all kinds of long oblique fracture resets and threads a needle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention
.
The present invention is specifically described by example below in conjunction with accompanying drawing.
Detailed description of the invention
Hollow pointed tooth fracture reposition instrument is provided with hollow pointed tooth (1; 5); jaw arm (2); holding handle (3); clamping screw (4); when holding handle (3) being pressurizeed in opposite directions during reset; jaw arm (2) is relatively close; drive two hollow pointed tooths (1; 5) relatively near and clamp bone block, lock bolt (4) simultaneously and can maintain and reset stable, now fixing draw point can be selected to pierce fixing draw point through the guiding protective effect of hollow pointed tooth according to requirements of operation; ensure that fixed-direction is accurate and fixing stablizing of threading a needle, operation high-efficient simple.Can be used for Patella fracture, olecranal fracture, medial and lateral malleolus fracture isostension steel wire internal fixtion and the reset of long oblique fracture are threaded a needle fixing.
The integration operation that the present invention's application achieves the reduction of the fracture in bone surgery, fixes, threads a needle, also can be used for traction therapy of bone simultaneously, has simple to operate, accurately safe and reliable during replacement and fixation, saves time and manpower, improves the advantages such as surgical quality.
