Abstract

The utility model discloses a lower extremity joint CT scan auxiliary frame, relating to a medical instrument, and consisting of a vertical plate (1) and a horizontal plate (2). The utility model is characterized in that the vertical plate (1) is vertically fixed at an end of the horizontal plate (2), a baffle (3) is arranged at a center line of the inner surface of the vertical plate (1) and the horizontal plate (2); a plurality of via holes (4) are opened at the baffle (3), and the two sides of the vertical plate (1) and the horizontal plate (2) are respectively provided with a fixed ring (5) corresponding to the via holes (4) on the baffle (3). The utility model has the advantages: the structure is simple, the operation is convenient, the scanning is accurate, the quantity of X rays is effectively reduced, diagnosis accuracy is improved and the utility model provides reliable treatment basis for clinic.

Description

Joint of the lower extremity CT scan auxiliary frame

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of auxiliary frame that uses on CT scanner.

Background technology

At present, in clinical diagnosis disease, CT scan has been the routine examination method, and is especially better to the sensitivity and the specificity of skeleton and soft tissue lesions, better to the demonstration of extent of disease, the paired observation before and after draft scheme before the favourable Rhizoma Atractylodis Macrocephalae and the treatment.But when the CT examination joint of the lower extremity, since position and patient, the lower limb movability, and the bilateral joint is difficult for influencing image quality on same scanning line, is difficult to the both sides contrast, brings difficulty to medical diagnosis on disease.Simultaneously because of the joint not on same scanning line, cause scanning the number of plies and increase, thereby cause the patient to increase unnecessary X ray amount and machine loss.

Summary of the invention

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and scanning accurately effectively reduces the X ray amount, improves accuracy rate of diagnosis, gives the clinical joint of the lower extremity CT scan auxiliary frame that reliable treatment foundation is provided.

The purpose of this utility model is achieved in that this joint of the lower extremity CT scan auxiliary frame is made up of riser and transverse slat, riser is vertically fixed on transverse slat one end, on the inner surface centrage of riser and transverse slat, be provided with baffle plate, on baffle plate, have a plurality of through holes, be respectively equipped with in the both sides of riser and transverse slat and the corresponding retainer ring of through hole above the baffle plate.

When specifically using this utility model, auxiliary frame is placed the head of a bed center of CT scanner, when checking knee joint, ankle joint, tarsometatarsus phalangeal joint, employing is lain on the back, both legs are placed on baffle plate both sides above the transverse slat respectively, the vola is close on the riser of baffle plate both sides, pass retainer ring and corresponding through hole with fixing band, instep and lower limb are separately fixed on riser and the transverse slat, make joint of the lower extremity on a plane of scanning motion, under the prerequisite that reduces the X ray amount, fully show each skeleton and little joint, be beneficial to diagnostic imaging.

Advantage of the present utility model: simple in structure, easy to use, scanning accurately effectively reduces the X ray amount, improves accuracy rate of diagnosis, and the clinical reliable treatment foundation that provides is provided.

Description of drawings

Accompanying drawing is a structure chart of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail: this joint of the lower extremity CT scan auxiliary frame is made up of riser 1 and transverse slat 2, riser 1 is vertically fixed on transverse slat 2 one ends, on the inner surface centrage of riser 1 and transverse slat 2, be provided with baffle plate 3, on baffle plate 3, have a plurality of through holes 4, be respectively equipped with in the both sides of riser 1 and transverse slat 2 and the 4 corresponding retainer rings 5 of through hole above the baffle plate 3.The making material can select for use wooden or the lucite manufacturing forms.

Claims

1. joint of the lower extremity CT scan auxiliary frame, form by riser (1) and transverse slat (2), it is characterized in that riser (1) is vertically fixed on transverse slat (2) one ends, on the inner surface centrage of riser (1) and transverse slat (2), be provided with baffle plate (3), on baffle plate (3), have a plurality of through holes (4), be respectively equipped with in the both sides of riser (1) and transverse slat (2) and the corresponding retainer ring of through hole (4) (5) above the baffle plate (3).
