Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment of the invention provides a tissue expanding instrument for a bone shielding operation under a mirror, which comprises a slide bar 1, a sliding adjusting fixer 2 and a supporting component 3, wherein the sliding adjusting fixer 2 is sleeved outside the slide bar 1, one end of the supporting component 3 is fixed on the slide bar 1, and the other end is fixed on the sliding adjusting fixer 2; thus, the sliding adjustment fixer 2 is pushed to move along the sliding rod 1, and the sliding adjustment fixer 2 drives the stretching assembly 3 to stretch into an X shape, so that the stretching of the subscapular muscles is realized.
The opening assembly 3 comprises a fixing rod 31, a first X-shaped bracket 32 and a second X-shaped bracket 33, one end of the fixing rod 31 is fixed on the sliding adjustment fixer 2, the other end of the fixing rod is arranged on the sliding rod 1 and is connected with one ends of the first X-shaped bracket 32 and the second X-shaped bracket 33, and the other ends of the first X-shaped bracket 32 and the second X-shaped bracket 33 are fixed on the sliding rod 1, so that the sliding adjustment fixer 2 drives the fixing rod 31 to move forwards, and the fixing rod 31 pushes the first X-shaped bracket 32 and the second X-shaped bracket 33 to form an X-shaped structure.
The middle parts of the first X-shaped bracket 32 and the second X-shaped bracket 33 are connected through a compressible connecting rod 34, and the volume of the spreader can be reduced through the connecting rod 34.
The first X-shaped bracket 32 and the second X-shaped bracket 33 each include a first stay 321 and a second stay 322, and a middle portion of the first stay 321 is hinged to a middle portion of the second stay 322, so that the first stay 321 and the second stay 322 cooperate to form an X-shape.
