Thread driving type force arm orthopedics traction device

Abstract

The invention discloses a thread driving type force arm orthopedics traction device, which comprises a handhold rod and supporting pillars; the outside of the middle of the handhold rod is sleeved with an anti-slide sleeve, left and right sides of the handhold rod are symmetrically provided with the supporting pillars; the lower ends of the supporting pillars are fixed with supporting plates, andthe supporting plates are used for facilitating the vertical placement of the device; driving cavities are not arranged in the supporting pillars, and the inner parts of the driving cavities are vertically provided with lifting screw bars; the upper ends of the lifting screw bars are connected and fixed with the output ends of lifting motors, and the lifting motors are fixed at the top parts in the driving cavities; the lower ends of the lifting screw bars are rotationally connected with the bottom parts of the driving cavities; left and right supporting pillars are glidingly provided with lifting slide blocks towards the opposite face. The thread driving type force arm orthopedics traction device is simple and reasonable in structure, and facilitates the skeletal fixation, reduces the pain in treatment, and is good for improving the working efficiency of workers; the thread driving type force arm orthopedics traction device is strong in practicability.

Description

technical field [0001] The invention relates to the technical field of medical orthopedic equipment, in particular to a screw drive type force arm orthopedic traction device. Background technique [0002] Now the methods of limb traction include skin traction and bone traction: skin traction is mainly used for elderly patients and children under 8 years old. Its effective traction force is small, and the skin is prone to blisters due to traction tension. Bone traction is commonly used in orthopedic clinics. However, the current clinical method is: use a hammer to drive a Kirschner wire or Steiner wire from one side of the bone, and pass through the bone marrow cavity to penetrate the opposite side skeletal muscle and skin. Patients have fear before traction, and in this method, the traction needle has to pass through the bone marrow cavity and run through the opposite side. When the traction is to be released in the future, the traction needle also has to pass through the bo...

Problems solved by technology

[0002] Now the methods of limb traction include skin traction and bone traction: skin traction is mainly used for elderly patients and children under 8 years old. Its effective traction force is small, and the skin is prone to blisters due to traction tension. Bone traction is commonly used in orthopedic clinics. However, the current clinical method is: use a hammer to drive a Kirschner wire or Steiner wire from one side of the bone, and pass through the bone marrow cavity to penetrate the opposite side skeletal muscle and skin. Patients have fear before traction, and in this method, the traction needle has to pass through the bone marrow cavity and run through the opposite side. When the traction is to be released in the future, the traction needle also has to pass through the bone marrow cavity, and it is difficult to achieve orthopedic disinfection with povidone iodine and alcohol. Sterilization requirements increase the chance of deep infection, leading to the possibility of nosocomial infection. At the same time, during the process of inserting the traction needle, the external force and vibration will cause aggravated pain at the fracture site of the affected limb, increase the pain of the patient, and even induce other diseases, such as Hypertension, Asthma, etc.

[0003] In order to solve the above problems, an orthopedic retractor is disclosed in the existing patent announcement number CN206587023U, but this device needs to be adjusted manually, and the operation is relatively cumbersome. bring more pain
