Reciprocating linear saw and cutting method thereof

Abstract

The invention discloses a reciprocating linear saw. The reciprocating linear saw comprises a transmission mechanism, a cutting line and a power device. The power device is connected with the cutting line through the transmission mechanism. The cross section of the cutting line is in a triangular shape. The transmission mechanism comprises a wheel disc, a worm, a turbine connection sleeve, a turbine and a coupler. The reciprocating linear saw is mainly used for a ligament cutting operation, for example, a mouse hand. The reciprocating linear saw is a novel medical electric tool used for the ligament cutting minimally invasive operation. The cutting line is fixed to a guide needle and penetrates from one end of a ligament to the other end during the operation, the cutting line is then brought out and fixed to two rotating pins of the linear saw, a power switch is turned on, and then operation can be started. Therefore, completeness of the hand shape of a patient can be ensured, and the treatment and rehabilitation period of the patient is shortened.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a reciprocating wire saw and a cutting method thereof. Background technique [0002] Jigsaws are used in minimally invasive procedures for conditions such as mouse hands. The traditional operation for mouse hand and other symptoms is to cut the skin and flesh of the hand, then use other cutting tools to cut off the ligament, and then suture the skin and flesh; this operation takes a long time and will bring great pain and recovery time to the patient; In order to save operation time, shorten postoperative recovery time and relieve patients from suffering more pain during operation, the wire saw was invented. Contents of the invention [0003] The object of the present invention is to provide an easy-to-operate reciprocating wire saw and its cutting method, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present ...
