Abstract
This utility model belongs to medical instruments field, and disclose a kind of fractured near end of thighbone dynamic hip screw fixed guider, one end of described guider is substrate, and substrate is connected with joint pin, and one end of joint pin is hands handle; Described substrate with joint pin is connected with multiple parallel guide pin pipe, the two ends of guide pin pipe are guide pinhole, are opened on substrate and joint pin respectively.During use, have an X-rayed after first an optional guide pinhole pierces guide pin, then select required guide pinhole according to actual needs.This guide structure is simple, and guide-localization is precisely reliable, can shorten operating time, reduces intraoperative hemorrhage and doctors and patients' x-ray radiation, has good result of use.
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 through open reduction internal fixation treatment.Dynamic hip screw (DHS) internal fixtion treats the most frequently used operation method of fractured near end of thighbone at present, location guide pin is inserted in one of key operation of operation, which determine the position of screw in neck of femur and direction, 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, 1 piece of guide pin can only be pierced, as higher or on the low side in found position after piercing guide pin in art, often need to take out guider and guide pin, again pierce after adjustment, as dissatisfied, need repetitive operation again, cause needing in art repeatedly to carry out C-arm X-ray machine perspective, have very large injury to patient and doctor.
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, and substrate is connected with joint pin, and one end of joint pin is hands handle; Described substrate with joint pin is connected with multiple parallel guide pin pipe, the two ends of guide pin pipe are guide pinhole, are opened on substrate and joint pin respectively.
During 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-arm X-ray machine perspective, Lateral approach is made under greater trochanter of femur, expose periosteum, under guider substrate is placed in 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 select according to actual needs to change guide pinhole under C-arm X-ray machine perspective, pierce guide pin, until position is satisfied, carry out DHS routine operation afterwards.
The invention has the beneficial effects as follows: guide-localization is precisely reliable, can shorten operating time, reduces intraoperative hemorrhage and doctors and patients' x-ray radiation, to raising surgical quality, there is positive role.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
In figure, 1 is substrate; 2 is guide pin pipes; 3 is joint pins; 4 is hands handles; 5 is necks of femur; 6 is lateral side of femur faces; 7 is fracture lines; 8 is guide pins; 9 is guide pinholes.
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, substrate 1 is connected with joint pin 3, and one end of joint pin 3 is handle 4; Described substrate 1 with joint pin 3 is connected with multiple parallel guide pin pipe 2, the two ends of guide pin pipe 2 are guide pinhole 9, are opened on substrate 1 and joint pin 3 respectively.
The present invention in use, during use, patient is flat to crouch on extension table, keep suffering limb outreach adduction, see under C-arm X-ray machine perspective that fracture 7 resets well, Lateral approach is made under greater trochanter of femur, expose periosteum, under guider substrate 1 is placed in 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 direction, then selects according to actual needs to change guide pinhole 9 under C-arm X-ray machine perspective, pierces guide pin 8, until position is satisfied, carry out DHS routine operation afterwards.
