Embodiment Construction

[0018] The implementation of a traction bow of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] The first embodiment of a traction bow of the present invention is as follows: Figure 1 to Figure 7 As shown, a traction bow of the present invention mainly includes a right clamping arm 1, an external connecting body 2, a left clamping arm 3, a transmission wire shaft 4, a guide shaft 5, a bone needle 6, a locking pin screw 7, a pin 8 and a handle 9. A collar I4-1 is arranged in the middle of the transmission thread shaft 4, and a thread shaft is provided at both ends. The threads of the thread shafts at both ends of the collar I4-1 are in opposite directions, the left end is a right-handed thread shaft, and the right section is A left-handed silk shaft, or a left-handed silk shaft at the left end, and a right-handed silk shaft at the right section. One end of the silk shaft is provided with an open slot 4-3, and a hand...

Abstract

The invention discloses a traction bow. The traction bow mainly comprises a right clamping arm, an outer connection body, a left clamping arm, a threaded transmission shaft, a guide shaft, a bone needle, a needle locking nut, a pin and a handle. The outer connection body is used for being connected with an external apparatus of the traction bow and is arranged in the middle of the threaded transmission shaft. Through cooperation of the pin, the outer connection body can only rotate relative to the threaded transmission shaft and cannot move. The left clamping arm and the right clamping arm are arranged at two ends of the threaded transmission shaft respectively. Left and right threads are arranged at two ends of the threaded transmission shaft respectively, and the handle is arranged at one end of the threaded transmission shaft. The guide shaft is arranged between the left clamping arm and the right clamping arm to guide the both to move. During operation, the handle can be screwed to adjust the distance between the left clamping arm and the right clamping arm, so that the traction bow is enabled to adapt to patients in different shapes and factures at different parts, the outer surfaces of the parts are clamped, and the bone needle is fixed at the front ends of the left clamping arm and the right clamping arm. The traction bow can substitute for heel bone traction bows, thigh bone traction bows and humerus traction bows, thereby being multifunctional.

Description

technical field [0001] The invention relates to a reducer for traction of limb fractures in fracture operations, belonging to the technical field of orthopedic surgical instruments. Background technique [0002] Fractures of the femur, tibia, humerus and other extremities are common clinically, and the use of traction bows during surgical treatment is a common method for traction reduction. However, some problems were also found during use, for example, the width of the traction arch required by the femur and humerus is different, and the width of the traction arch required by fatter patients and thinner patients in the same part is also different. The currently commonly used traction bows cannot meet the needs of different patients at the same time. Contents of the invention [0003] The invention discloses a traction bow, which overcomes the above-mentioned defects, and mainly includes a right clamping arm, an external connecting body, a left clamping arm, a driving wir...
