Intramedullary pressuring robot for replacing lateral bone movement

Abstract

The invention discloses an intramedullary pressuring robot for replacing lateral bone movement and relates to the technical field of medical instruments. The intramedullary pressuring robot for replacing the lateral bone movement comprises a casing body and two pressuring mechanisms arranged on two ends of the casing body, two ends of the casing body are respectively connected with each end opposite to the two pressuring mechanisms in a thread manner. The intramedullary pressuring robot for replacing the lateral bone movement moves downward through a motion bar to drive a moveable piston in awater supply column to move downward, so that water in the water supply column passes through a water supply pipeline to enter an annular water capsule and the diameter of the annular water capsule isenlarged, the lateral bone movement is carried out through the annular water capsule, risks of the lateral bone movement are reduced, and comfort level is high, and the robot has the characteristicsof less trauma in operation, no need of bone flaps, no surgery needed at the high risk front edge of a tibia, no need of chiseling the bone flaps, no various complications caused by external fixingstents, effectively reducing hospital stays of a patient, continuous effectiveness, and long-time wearing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intramedullary pressure-applying robot that replaces transverse bone transfer. Background technique [0002] Transverse tibial bone transfer has been used more and more widely in the treatment of diabetic feet, and it is especially effective for patients with distal vascular occlusion. However, there are still many deficiencies in lateral bone transfer. Lateral bone transfer requires the following operations. Open a 2*12 cm bone flap, install a special external fixator, and ask to lift the bone flap at a rate of 1 mm per day. After 2 weeks, gradually push back the bone flap, and finally complete the treatment, but the external fixator cannot be removed immediately. Frame, must wait 8-12 weeks, after the bone flap pushed back healed, the outer frame can be removed. [0003] In this process, there will be some problems: the operation can easily lead to pre-tibial skin n...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an intramedullary pressure-applying robot that replaces the lateral bone transfer, which solves the problem of large trauma and certain risks in the existing lateral bone transfer method, and the treatment process is long and expensive. The patient's longer hospital stay and poor comfort
