Abstract

A bone traction bow with an adjustable hanging position comprises a wire needle, wherein the wire needle penetrates through the bone traction bow, a pipe body at the arc top section of the bone traction bow is in an external thread form, and a hanging ring is screwed on a bone tractor; the utility model discloses simple structure, convenient to use, low in cost. Through simple structural transformation, the center of gravity deviation correction in the process of drawing the Si-type needle is realized. Avoids the bone traction deflection and has very positive effect on the subsequent detumescence bone setting.

Description

Bone traction bow with adjustable hanging position

Technical Field

The utility model relates to a bone fracture surgery field especially relates to a hang position adjustable bone traction bow.

Background

Surgery is a science for researching the occurrence, development law and clinical manifestations, diagnosis, prevention and treatment of surgical diseases, is a professional department taking surgical excision and repair as main treatment means, and relates to treatment means refutation. The fracture and bone fracture is prepared before operation, and the operation process of the adopted Stess needle traction has certain problems which are not overcome yet. In the standard requirements of operation, the needle is directly aligned when the Stess needle penetrates through the bone, and the distal bone of the fracture position can be vertically stretched and drawn after the traction bow is hung. However, the process of bone penetrating operation of the Stess needle is completely operated by the operator manually, and the situation that the needle body is slightly inclined and inclined is inevitable, so that the stretching and inclined situation is easy to occur in the traction process, and the subsequent detumescence and surgical coaptation are not facilitated.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the shortcomings of the prior art, and to provide a bone traction bow with adjustable hanging position, which has simple structure and convenient use. The radian of the traction bow is integrally adjusted through the thread pitch adjustment of the threaded sleeve, so that the position and the angle of a suspension ring of the traction bow deviate to a certain extent, and the correction can be effectively adjusted under the condition that the Si-type needle is slightly inclined.

The device includes a stent needle that is passed through the bony traction arch.

The arc top section pipe body of the bone traction bow is in an external thread form, a suspension ring is screwed on the bone traction bow, and the suspension ring is used for tying a connection rope to hang a heavy object.

Furthermore, a rotary lantern ring is screwed on the bone traction bow, and a suspension ring is hinged on the rotary lantern ring. That is to say, through rotating lantern ring rotational position, make the suspension ring position take place certain skew, that is to say the heavy object center of gravity of fishing takes place certain skew, plays the effect of rectifying.

Further, the side of the bone traction bow and two ends of the S-shaped needle are respectively sleeved with a fixing sleeve, the fixing sleeve is arranged on the S-shaped needle in a sliding mode, a bolt penetrates through the fixing sleeve, the fixing sleeve can be limited by screwing, and the bone traction bow is limited.

Furthermore, the central position of the bottom of the inner surface of the suspension ring body is in a concave form and is used for more stable fastening and fixing of the fastening rope.

The utility model discloses during the use, after the si formula needle passed fracture position distal end skeleton, hang bone traction bow both ends respectively at si formula needle both ends, then according to the condition of wearing to establish of si formula needle, twist and move the rotation lantern ring and carry out manual rectifying, just also through the adjustment to the hanging position, carry out centrobaric accurate correction.

The utility model has the advantages that: the utility model discloses simple structure, convenient to use, low in cost. Through simple structural transformation, the center of gravity deviation correction in the process of drawing the Si-type needle is realized. Avoids the bone traction deflection and has very positive effect on the subsequent detumescence bone setting.

The objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.

Detailed Description

Referring to fig. 1, the bone traction bow with adjustable hanging position of the present invention comprises a si-type needle 1, wherein the si-type needle 1 penetrates through a bone traction bow 2.

The arc top section pipe body of the bone traction bow 2 is in an external thread form, a suspension ring 4 is screwed on the bone traction bow, and the suspension ring 4 is used for tying a connecting rope to hang a heavy object.

Furthermore, a rotary lantern ring 3 is screwed on the bone traction bow 2, and a suspension ring 4 is hinged on the rotary lantern ring 3. That is, the position of the hanging ring 4 is deviated by rotating the rotating ring 3, that is, the gravity center of the fishing weight is deviated to a certain extent, so as to perform the function of correcting the position.

Further, 2 sides of the bone traction bow, 1 both ends of the si type needle are respectively sleeved with a fixing sleeve, the fixing sleeve is arranged on the si type needle 1 in a sliding mode, a bolt is arranged on the fixing sleeve in a penetrating mode, the fixing sleeve can be limited by screwing, and therefore the bone traction bow 2 is limited.

Furthermore, the central position of the bottom of the inner surface of the ring body of the suspension ring 4 is in a concave form and is used for more stable fastening and fixing of a fastening rope.

The utility model discloses during the use, after the si formula needle 1 passes fracture position distal end skeleton, hang 2 both ends of bone traction bow at si formula needle 1 both ends respectively, then according to the condition of wearing to establish of si formula needle 1, twist and move the rotation lantern ring 3 and carry out manual rectifying, also exactly through the adjustment to the hookup location, carry out centrobaric accurate correction.
