Abstract
The invention belongs to the field of medical apparatus and instruments and discloses a guider for fixing dynamic hip screws for proximal femoral fractures. A base plate is arranged at one end of the guider; a connection post is connected to the base plate; a handle is arranged at one end of the connection post; a plurality of parallel needle guide tubes are connected to the base plate and the connection post; needle guide holes are formed in two ends of the needle guide tubes and opened on the base plate and the connection post. When using, a guide needle is drilled into an optional needle guide hole firstly and then the required needle guide holes are selected according to the actual requirement. The guider is simple in structure, accurate and reliable in guide and location, good in use effect and capable of shortening operation time and reducing hemorrhage during operation and medical X-ray radiation.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of fractured near end of thighbone dynamic hip screw fixed guider.
Background technology
Fractured near end of thighbone is one of common clinically fracture, mainly by open reduction internal fixation treatment.In dynamic hip screw (DHS), be fixedly to treat at present the most frequently used operation method of fractured near end of thighbone, one of key operation of operation is to insert location guide pin, it has determined position and the direction of screw in neck of femur, in art, screw implantation site is the principal element of prevention femoral cut, the improper fracture fixation that will cause of guide pin implantation site is insecure, the generation of the complication such as malunion of fracture and femur head necrosis.
Use conventional DHS guider, can only pierce 1 piece of guide pin, after piercing guide pin in art, as found, position is higher or on the low side, often need to take out guider and guide pin, after adjustment, again pierce, as dissatisfied, need repetitive operation again, cause needing repeatedly to carry out C type arm X-ray machine perspective in art, patient and doctor are had to very large injury.
Summary of the invention
For overcoming above-mentioned shortcoming, the object of the present invention is to provide a kind of guide-localization fractured near end of thighbone dynamic hip screw fixed guider accurately.
The present invention is achieved by the following technical solutions: a kind of fractured near end of thighbone dynamic hip screw fixed guider, and one end of described guider is substrate, is connected with joint pin on substrate, one end of joint pin is hands handle; Described substrate with on joint pin, be connected with multiple parallel guide pin pipes, the two ends of guide pin pipe are guide pinhole, are opened on respectively substrate and joint pin.
When use, patient is flat to crouch on extension table, keep suffering limb outreach adduction, after seeing that the reduction of the fracture is good under C type arm X-ray machine perspective, under greater trochanter of femur, make Lateral approach, expose periosteum, guider substrate is placed under greater trochanter, be close to lateral side of femur face, control top rake well, first an optional guide pinhole pierces guide pin by guide pin pipe to neck of femur direction, then under C type arm X-ray machine perspective, select according to actual needs to change guide pinhole, pierce guide pin, until position is satisfied, carry out afterwards DHS routine operation.
The invention has the beneficial effects as follows: guide-localization is precisely reliable, can shorten operating time, reduce intraoperative hemorrhage and doctors and patients' x-ray radiation, there is positive role to improving operation quality.
Brief description of the drawings
Accompanying drawing is structural representation of the present invention.
In figure, 1 is substrate; The 2nd, guide pin pipe; The 3rd, joint pin; The 4th, hands handle; The 5th, neck of femur; The 6th, lateral side of femur face; The 7th, fracture line; The 8th, guide pin; The 9th, guide pinhole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in drawings, a kind of fractured near end of thighbone dynamic hip screw fixed guider, one end of described guider is substrate 1, is connected with joint pin 3 on substrate 1, one end of joint pin 3 is handle 4; Described substrate 1 with on joint pin 3, be connected with multiple parallel guide pin pipes 2, the two ends of guide pin pipe 2 are guide pinhole 9, are opened on respectively substrate 1 and joint pin 3.
The present invention in use, when use, patient is flat to crouch on extension table, keep suffering limb outreach adduction, after seeing under C type arm X-ray machine perspective that fracture 7 resets well, under greater trochanter of femur, make Lateral approach, expose periosteum, guider substrate 1 is placed under greater trochanter, be close to lateral side of femur face 6, control top rake well, first an optional guide pinhole 9 pierces guide pin 8 by guide pin pipe 2 to neck of femur 5 directions, then under C type arm X-ray machine perspective, selects according to actual needs to change guide pinhole 9, pierces guide pin 8, until position is satisfied, carry out afterwards DHS routine operation.
