The stent comprises a stent main body, a foot fixer, a pedal, an inner tube and an adjusting piece, wherein the inner tube is fixedly arranged on the stent main body; the adjusting piece is arranged on the inner tube in a rotatable and sliding mode; and both the foot fixer and the pedal are fixedly connected with the adjusting piece. The stent for assisting the CT diagnosis of the tarsometatarsal joint injury can assist a patient in maintaining a foot at a plantar flexion ectropion position in the CT diagnosis process, so that diagnosis is facilitated, the requirement of the CT diagnosis for the flexion direction of the foot of the patient is met, the CT diagnosis operation can be accurately performed, and the accuracy and the precision of the diagnosis result are ensured.
Description
Technical field
The present invention relates to the medical equipment field, relate in particular to the support of a kind of auxiliary CT diagnosis tarsometatarsal joints damage.
Background technology
Damage though the tarsometatarsal joints fracture is rare foot, can have a strong impact on patients ' life quality in case the tarsometatarsal joints fracture takes place, influence was bigger after diagnosis early, early treatment were fullyed recover from an illness to the patient.Because the performance in the inspection of X sheet of tarsometatarsal joints fracture is often not obvious, its rate of missed diagnosis Da Gaoda 20%.And C T is according to human body different tissues different to the absorption of X line and transmitance; Using the high instrument of sensitivity measures human body; The data input electronic computer that is obtained be will measure then, after electronic computer is handled data, section or spatial image that human body is examined the position just can be photographed; Find the tiny pathological changes at any position in the body, therefore compare X sheet inspection CT examination and then have more advantage.
Maximum magnitude ground reduces rate of missed diagnosis though existing many documents are illustrated in when carrying out CT examination that patient's foot need keep that the sole of the foot is bent the position of turning up (sole of the foot is bent 6 °, turns up 13 °), and the patient often can't keep this position completion CT examination because of pain.At this moment, need the use auxiliary stand to keep the auxiliary CT examination that carries out of position of patient's foot.And the support (like the Brown's frame) that now general orthopaedics is used in the medical science can't be kept the position of patient's foot, makes troubles to CT examination, cause diagnosing inaccurate easily or the diagnostic result precision not high.In addition, the orthopaedics support of using at present is printing opacity scarcely, can't be used for CT examination.
Summary of the invention
The support that the purpose of this invention is to provide the damage of a kind of auxiliary CT diagnosis tarsometatarsal joints; This support can be assisted the patient that its foot is maintained the sole of the foot in the CT diagnostic procedure and bent the position of turning up; Diagnose requirement conveniently to diagnose and to meet CT to patient's foot bends orientation; Thereby make the CT diagnostic operation accurately to carry out, guaranteed the accuracy rate and the precision of diagnostic result.
For realizing above-mentioned purpose; The present invention provides the support of a kind of auxiliary CT diagnosis tarsometatarsal joints damage; Said support comprises rack body, foot's fixture, footboard, interior pipe and adjustment part; Pipe is fixedly installed on the said rack body in said, and said adjustment part rotatably is slidingly mounted on the said interior pipe, and said foot fixture and footboard all are fixedly connected with said adjustment part.
Preferably, said adjustment part comprises transverse tube and vertical tube, said transverse tube rotatably be sheathed on said on the pipe, and said transverse tube and vertical tube are mutual vertical and make said adjustment part T-shaped.
Preferably, offer at least two and ranked first through hole on the pipe in said, correspondingly, offer at least two second through holes on the said transverse tube, a locking pin passes corresponding said second through hole and first through hole and manages in said so that said adjustment part is fixed in.To close said second through hole and different rows' first through hole corresponding fixing through rotating said transverse tube, thus can with said adjustment part be fixed on said in the different angles position of pipe, to satisfy different diagnosis requirement.
Preferably, each is arranged said first through hole and in said, manages axially-aligned.Make said transverse tube can in said, manage its axial direction of upper edge and slide and regulate and move to desired location, and pass corresponding said second through hole and first through hole through said locking pin and said transverse tube is fixed in manages in said.
Preferably, between said first through hole of adjacent two rows 6 ° at interval, and between adjacent two said second through holes 6 ° at interval.With the equal angular that is set between interval between said first through hole of adjacent two rows and adjacent two said second through holes; To guarantee that said second through hole is corresponding with said first through hole and fixing said transverse tube is managed in said; In addition at interval angle value is set to 6 °, thereby is fixed in said interior Guan Shanghou when said adjustment part, and the patient lies on the back on the said support and after its foot is fixed on the said foot fixture; Can guarantee that it is 6 ° that its foot sole of the foot is bent; Make the sole of the foot bend the requirement that degree meets CT examination, conveniently carrying out CT examination, and guarantee that inspection can carry out all sidedly.
Preferably, the support of said auxiliary CT diagnosis tarsometatarsal joints damage also comprises a support bar, and said support bar is fixedly connected with said vertical tube, and said footboard is fixedly installed on the said support bar.
Preferably, offer at least one through hole that ranked third on the said vertical tube, correspondingly, offer fourth hole on the said support bar, a locking pin passes said third through-hole and fourth hole so that said support bar is fixed on the said vertical tube.
Preferably, each arranges said third through-hole in the arrangement that tilts of said vertical tube, and the gradient of said third through-hole is 13 °.So be provided with, when carrying out CT examination, can make patient's foot keep the sole of the foot and turn up 13 °, make the degree of turning up of the sole of the foot meet the requirement of CT examination,, guarantee that further inspection can carry out all sidedly conveniently to carry out CT examination.
Preferably, said foot fixture semicircular in shape, and semi-circular soft pad also is installed on the inwall of said foot fixture.The ankle of the corresponding human body of said foot's fixture and be set to semicircle; Thereby can make things convenient for and the foot of immobilized patients firmly; And said semi-circular soft pad is set on the inwall of said fixture; In the time of in patient's foot is inserted said fixture, can be by the edge scratch of said fixture, said semi-circular soft pad can improve the comfort level of patient in the CT examination process simultaneously.
Preferably, the both sides of said foot fixture also are provided with soft auxiliary band.Said soft auxiliary band can be assisted the foot of said foot fixture immobilized patients, fixedly the time, can not bring pain to the patient simultaneously.
Compared with prior art, beneficial effect of the present invention: because said adjustment part rotatably is slidingly mounted on the said interior pipe; Said foot fixture and footboard all are fixedly connected with said adjustment part; But in said, manage the angle and the position of slip and the said footboard of rotation flexible and foot's fixture through said adjustment part; Thereby when the patient lay on the back support in the damage of said auxiliary CT diagnosis tarsometatarsal joints, the foot that this support can be assisted the patient maintained according to the demand of CT examination and is fit to and angle and position accurately, has guaranteed the requirement of CT diagnosis to patient's foot bends orientation; Can accurately carry out thereby guaranteed to diagnose, and guarantee the precision of diagnostic result.
