Description

Phalanx steel needle fixing clamp

Technical Field

The utility model relates to the field of medical equipment, concretely relates to indicate bone steel needle fixation clamp of orthopedics external fixation usefulness.

Background

The traditional mode of phalangeal fracture is to apply a phalangeal plate, restore the phalangeal plate through open type debridement and implantation of a corresponding titanium alloy plate, and solve the fracture problem in an internal fixation mode. Although the phalangeal fracture can be fixed through the titanium plate, the wound surface is large, and the fixing position of the titanium plate is not easy to select and the strength is not enough for the complex fracture or multi-section fracture. Especially the type of fracture, shortening or deformity near and across the joint, requiring orthopedic phalangeal surgery, must be treated by external fixation techniques.

At present, the forms of domestic external fixation brackets are various, only one side is mainly fixed, the steel needle is penetrated near the fracture broken end, and 2-4 steel needles fix the fracture through the external bracket to achieve the treatment purpose. The single-side fixing mode has the following disadvantages: (1) the stability is poor, the rotation is easy to generate, the slight shaking of the fractured end is not beneficial to the healing of the fracture; (2) the unilateral fixing structure is unstable, the operation is inconvenient, the limited conditions are more, the single needle can not be operated singly, the adjustment angle is limited, the needle threading position is limited, and the needle threading position can not be selected randomly; (3) the space for threading the needle is small when crossing the joint and near the joint end.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a stable in structure, convenient operation, can realize that multi-angle many planes wear the finger bone steel needle fixation clamp of needle.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a indicate bone steel needle fixation clamp, includes the rotator, articulates on the rotator has two relative pivoted screw rods, and the one end that articulates with the rotator on the screw rod is inner, the one end of keeping away from the rotator is the outer end, overlaps in proper order on every screw rod from interior to exterior to be equipped with down fixation clamp, go up fixation clamp and with screw rod threaded connection's compress tightly the knob.

Further, the aforementioned phalangeal steel needle fixing clip, wherein: each screw rod is sequentially sleeved with a gasket, a lower fixing clamp, an upper fixing clamp and a pressing knob in threaded connection with the screw rod from inside to outside.

Further, the aforementioned phalangeal steel needle fixing clip, wherein: the pressing knob is arranged in a conical body with patterns on the outer part.

Further, the aforementioned phalangeal steel needle fixing clip, wherein: a hexagonal boss is also arranged in the pressing knob.

Further, the aforementioned phalangeal steel needle fixing clip, wherein: the two screws are simultaneously hinged on a pin shaft penetrating through the rotating body.

Further, the aforementioned phalangeal steel needle fixing clip, wherein: the pin shaft is detachably arranged on the rotating body through a clamp spring.

Through the implementation of above-mentioned technical scheme, the utility model has the advantages that: the device can be pre-tightened manually, and is simple to operate; the rotary shaft structure is adopted, the angle adjusting range is large, and multi-angle and multi-plane needle threading can be realized; the stability is good, the three-dimensional fixing principle of multi-angle and multi-plane is met, the randomness of the fixing mode is realized, and the treatment and the fixation of any fracture type of phalangeal fracture in any form are met.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, 2 and 3, the phalangeal steel needle fixing clamp comprises a rotating body 1, two screws 2 which can rotate relatively are hinged to the rotating body 1, one end of each screw 2, which is hinged to the rotating body 1, is an inner end, and the other end, which is far away from the rotating body 1, is an outer end, and a gasket 6, a lower fixing clamp 3, an upper fixing clamp 4 and a pressing knob 5 which is in threaded connection with the screws 2 are sequentially sleeved on each screw 2 from inside to outside; in the embodiment, the pressing knob 5 is arranged in a conical body with patterns on the outer part, so that medical personnel can conveniently perform manual pre-tightening on a steel needle or a connecting rod arranged between the upper fixing position 4 and the lower fixing clamp 3, and the operation is very convenient; in the embodiment, the hexagonal boss 7 is further arranged in the compression knob 5, so that medical personnel can use a wrench to further screw the compression knob, and the operation is more convenient; in the embodiment, two screws 2 are hinged to a pin shaft 8 arranged on the rotating body 2 at the same time, so that the structure is simpler, and the purpose of free rotation of the screws in a plane can be achieved; in this embodiment, the pin shaft 8 is detachably mounted on the rotating body 2 through a snap spring, so that the pin shaft is more convenient to mount and dismount;

when the device is used, a steel needle 9 or a connecting rod is placed between an upper fixing clamp 4 and a lower fixing clamp 3, then a pressing knob is manually pre-tightened and fastened with a wrench, the upper fixing clamp 4 and the lower fixing clamp 3 are clamped to clamp the steel needle or the connecting rod in a pressurizing mode, then the rotating body 1 is matched with a screw rod 2, and 30-150-degree rotation in one plane of the steel needle is realized, so that the installation angle of the steel needle is adjusted; when in actual use, the positions of the steel needle and the connecting rod can be interchanged, and the clinical requirements can be flexibly and changeably met.

The utility model has the advantages that: the device can be pre-tightened manually, and is simple to operate; the rotary shaft structure is adopted, the angle adjusting range is large, and multi-angle and multi-plane needle threading can be realized; the stability is good, the three-dimensional fixing principle of multi-angle and multi-plane is met, the randomness of the fixing mode is realized, and the treatment and the fixation of any fracture type of phalangeal fracture in any form are met.
