Problems solved by technology

However, this operation has high requirements on the accuracy of the doctor's technical operation, and there are strict restrictions on the position of the osteotomy of the coracoid process, the position of the glenoid fixation, and the direction and length of the fixation screw.
It is difficult to be very precise by relying solely on the doctor's experience, which will affect the effect of the operation and even lead to irreversible complications

Embodiment 1

[0028] Embodiment 1: a kind of Latarjet surgical accurate displacement guide plate and its use method, comprise the following steps:

[0029] Step 1: Establish a scapula model: collect CT image data of the affected shoulder joint of the patient, import it into the surgical design simulation software, and reconstruct the 3D model of the scapula;

[0030] Step 2: Simulate Latarjet operation: Determine the osteotomy plane at the elbow of the coracoid process, and simulate the displacement of the intercepted coracoid process block to the anterior and inferior glenoid defect area to form the expected glenoid model after reconstruction, which is determined repeatedly from multiple planes The position of coracoid process displacement and fixation, after the position is determined, design two long cylindrical tube models to simulate the screw, adjust the position of the cylindrical tube, and measure the length of the cylindrical tube in the bone to determine the screw length;

Abstract

The invention discloses a precise displacement guide plate for a Latarjet operation and a using method of the precise displacement guide plate. The manufacturing method of the precise displacement guide plate for the Latarjet operation comprises the following steps that 1, a shoulder blade model is established; 2, simulating a Latarjet technology; 3, establishing a guide plate model; and 4, printing a guide plate model. The using method of the precise displacement guide plate for the Latarjet operation comprises the following steps that 1, the guide plate is disinfected and sterilized; 2, thecoracoid is stripped and trimmed to match the guide plate; 3, a glenoid cavity guide plate is attached to the glenoid cavity, a guide plate matching surface is fitted with the front lower edge of theglenoid cavity, and a guide needle is input along a guide pipe; 4, a guide needle is arranged in the glenoid canal, the rear lower face of the coracoid bone block is attached to the front face of theglenoid canal, and a hollow screw is tapped in along the guide needle; and 5, after coracoid displacement fixation is finished, the wound is sutured and closed layer by layer. The invention belongs tothe technical field of medical apparatus and instruments, and particularly relates to a high-precision and standardized precise displacement guide plate for a Latarjet operation and manufacturing andusing methods of the high-precision and standardized precise displacement guide plate for the Latarjet operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a Latarjet surgical precision displacement guide plate and a use method thereof. Background technique [0002] The shoulder joint is the joint most prone to dislocation, and more than 95% of them are anterior dislocations, and more than 22% of them have glenoid bone defects. Latarjet surgery becomes the only option for patients with combined glenoid bone defect with a defect greater than 20% or with redislocation after simple shoulder stabilization. However, this operation requires a high degree of precision in the technical operation of the doctor, and there are strict restrictions on the position of the osteotomy of the coracoid process, the position of the glenoid fixation, and the direction and length of the fixation screw. It is difficult to operate precisely with the experience of doctors alone, which will affect the effect of the operation and even lead to irr...
