Abstract
The utility model relates to an orthopedic bone needle bender. The bender comprises a pipe body, wherein a fixed handle is arranged at one end of the pipe body; a pressing block is fixed at the other end of the pipe body; a rod body is arranged in the pipe body in a clearance fit mode; one end of the rod body is hinged with a movable handle; a U-shaped opening corresponding to the pressing block is formed at the other end of the rod body; the rod body is hinged with the movable handle to form a first hinge point; the movable handle is hinged with the fixed handle to form a second hinge point; and a hinge hole of the first hinge point or the second hinge point is a strip-type hole. Through the technical scheme, a bone needle is pressed in the U-shaped opening by the pressing block and bent into a regular U shape, and a bone cannot be fractured when the bone needle penetrates into the bone.
Description
Technical field
This utility model relates to a kind of medical equipment, the medical bending device of particularly using in a kind of bone surgery.
Background technology
In the treatment of clinical fracture, often use the fixing fracture of Kirschner wire, behind fixing the end, need the bending of Kirschner wire backshank, imbed subcutaneous.Generally be with the free-hand bending of common vice in the prior art, need two people to cooperate and just can finish a clamping, a bending, two people must exert oneself simultaneously, and power thrusts is opposite, cooperate difficulty large, sometimes need repeatedly to carry out, cause doctor's fatigue and time waste, two pairs of pliers are in use owing to trembling, the good fracture site that resetted is misplaced again, cause fracture again to be shifted, so that affect knitting, bring misery to the patient, affect the treatment.Therefore can particularly periarticular fracture needs accurate, stable resetting especially, laborsaving light, the bending Kirschner wire seems particularly important exactly.
The patent No. is 01243920 utility model patent, a kind of medical bending device is provided, it is comprised of handle and sleeve two parts, the handle front portion is flat, the draw point holddown groove that several that differ with width above it are oblique, what such sleeve folded is V-shape, and spicule gos deep into just causing bone splits in the bone.
Summary of the invention
The purpose of this utility model provides the orthopaedics spicule lever that a kind of bending shape is regular U font.
For achieving the above object, this utility model is by the following technical solutions:
A kind of orthopaedics spicule lever, it comprises body, and an end of body is fixed handle, and the body other end is briquetting fixedly; The body internal clearance arranges the body of rod, and the hinged flexible handle of the body of rod one end, the body of rod other end are U-shaped mouthful corresponding with briquetting; Wherein, the pin joint of the body of rod and flexible handle is the first pin joint, and flexible handle and fixed handle are articulated and connected and form the second pin joint; The hinge hole of described the first pin joint or the second pin joint is bar hole.
The hinge hole of described the first pin joint is bar hole, and the hinge hole of the second pin joint is circular hole.
The hinge hole of described the first pin joint is circular hole, and the hinge hole of the second pin joint is bar hole.
Adopt this utility model of technique scheme, because briquetting is pressed into bending in U-shaped mouthful with spicule, bending shape is regular U font, and spicule gos deep into just can not causing bone splits in the bone.
Description of drawings
Fig. 1 is overall structure figure of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of orthopaedics spicule lever, it comprises body 1, and an end of body 1 is fixed handle 2, and body 1 other end is briquetting 3 fixedly.Briquetting 3 can directly be fixed on the body 1, also can be welded on the connecting plate, and this connecting plate and body 1 are solidified as a whole and get final product.Body 1 internal clearance arranges the body of rod 4, and the hinged flexible handle 5 of the body of rod 4 one ends, the body of rod 4 other ends are U-shaped mouthful 9 corresponding with briquetting, and spicule 11 is between U-shaped mouth 9 and briquetting 3 during use.
In this utility model, the body of rod 4 is the first pin joint 6 with the pin joint of flexible handle 5, and flexible handle 5 is articulated and connected with fixed handle 2 and forms the second pin joint 7; The hinge hole of above-mentioned the first pin joint 6 or the second pin joint 7 is bar hole.
When the hinge hole of the first pin joint 6 was bar hole 8, the hinge hole of the second pin joint 7 should be circular hole.At this moment, jointed shaft 10 is positioned at bar hole 8, and can carry out displacement in bar hole 8.
When the hinge hole of the first pin joint 6 was circular hole, the hinge hole of the second pin joint 7 should be bar hole.Like this, can be at the length intrinsic displacement of bar hole between flexible handle 5 and the fixed handle 2.
During use, spicule 11 is pressed flexible handle 5 between U-shaped mouth 9 and briquetting 3, and U-shaped mouthful 9 moves to left, and briquetting 3 is with spicule 11 bendings.
