Abstract

A lower limb joint CT scanning assistant stand belonging to medical instrument technique domain includes a transversal board(1) and a vertical board(2). The vertical board(2) is fixed on a terminal of the transversal board(1) vertically, two adjacent quadrate grooves(3) are disposed on the vertical board(2), and two arcuate grooves(4) correspondent to the two quadrate grooves(3) on the vertical board(2) are disposed on the transversal board(1). A through hole(5) is provided respectively on the frames of the two quadrate grooves(3) on the vertical board(2), and two through holes(6) are provided in the two arcuate grooves(4) on the other end of the transversal board. The advantages are: simple structure, convenient use, accurate scan, and the lower limb joint can be arranged in a same plane to reduce the X-ray quantity, display each bone and small joint sufficiently, and facilitate image diagnosis.

Description

Joint of the lower extremity CT scan auxiliary frame

Technical field

This utility model belongs to technical field of medical 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 to skeleton and better to the sensitivity and the specificity of 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 during the CT examination joint of the lower extremity, since position and patient, the lower limb movability, and the bilateral joint on same scanning line, does not influence image quality, 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 transverse slat and riser, riser is vertically fixed on above the end of transverse slat, on riser, be provided with two adjacent rectangular recess, be provided with on the transverse slat two respectively with riser on two corresponding arc grooves of rectangular recess.On the frame of two rectangular recess of riser, all be respectively equipped with a through hole, in two arc grooves of the transverse slat other end, be respectively equipped with two through holes.

When specifically using this utility model, auxiliary frame is placed the head of a bed center of CT scanner, check knee joint, ankle joint, during the tarsometatarsus phalangeal joint, employing is lain on the back, biped is put into the rectangular recess of riser, the biped vola is close to riser rectangular recess bottom surface, both legs are put into respectively in the arc groove on the transverse slat, by the through hole in through hole on the rectangle frame and the transverse slat one end arc groove instep and lower limb are fixed respectively with fixing band, make joint of the lower extremity on a plane of scanning motion, under the prerequisite that reduces X ray, 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 can make joint of the lower extremity on the same plane of scanning motion, effectively reduces the X ray amount, fully shows each skeleton and little joint, is beneficial to diagnostic imaging.

Description of drawings

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

The specific embodiment

Make this utility model with reference to accompanying drawing: this joint of the lower extremity CT scan auxiliary frame is made up of transverse slat 1 and riser 2, riser 2 is vertically fixed on above the end of transverse slat 1, on riser 2, be provided with two adjacent rectangular recess 3, be provided with on the transverse slat 1 two respectively with riser 2 on two rectangular recess, 3 corresponding arc grooves 4.On the frame of two rectangular recess 3 on the riser 2, all be respectively equipped with a through hole 5, in two arc grooves 4 of transverse slat 1 other end, be respectively equipped with two through holes 6.

Claims

1, a kind of joint of the lower extremity CT scan auxiliary frame, form by transverse slat (1) and riser (2), riser (2) is vertically fixed on above the end of transverse slat (1), it is characterized in that riser (2) is provided with two adjacent rectangular recess (3), be provided with on the transverse slat (1) two respectively with riser (2) on the corresponding arc grooves of two rectangular recess (3) (4).
