Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an instrument for correcting a certain distance of a cortical bone pore canal of a screw in an orthopedic operation to a specified direction.
Background
With the continuous development of orthopedic surgery, minimally invasive and precise orthopedics becomes mainstream nowadays, and the requirements on the position of a screw on a bone are higher and higher. The cortical bone tunnel of the screw is often offset from the target site due to minimally invasive and intraoperative exposure constraints. If the deviation is more than 5mm, the hole can be re-drilled after the position is determined, but if the nail hole deviation is less than 5mm, the drill bit can easily slide into the original hole channel or deviate from the target position again when the hole is re-drilled. Resulting in prolonged operation time and partial screw holes which reduce the screw fixation strength and even make the operation impossible. For example, when the intramedullary nail operation is carried out on fractures such as femur, tibia and the like, the far-end locking device is out of alignment, a drill bit cannot enter a lock hole of the intramedullary nail through an original bone hole, the deviation distance of the original bone hole is often smaller than 5mm, the drill bit often slides into the original bone hole when the bare-handed locking nail technology is applied to drilling, and the drill bit is easy to break when the angle drilling is adjusted. Similar situations may occur in some procedures where the placement of cannulated screws is highly desirable, such as procedures where the anterior and posterior columns of a pelvic fracture and the guide pin of the sacroiliac joint screw deviate from the ideal position and do not deviate so much.

The correction sleeve and the supplement core are made of 316 medical stainless steel.
Advantageous effects
The invention provides a nail hole corrector for an orthopedic operation, which is an instrument for correcting a bone pore canal with an improper position on a bone cortex in the orthopedic operation at a certain distance. The device consists of a correction sleeve, a correction sleeve holding arm, a complementary core and a complementary core holding arm; the correction sleeve is fixedly connected with the correction sleeve holding arm, the supplement core is connected with the supplement core holding arm, and the supplement core is positioned in the correction sleeve and is installed in a matching way with the correction sleeve; revise sleeve pipe cross-section central authorities and be equipped with into 8 font guiding hole, the guiding hole runs through and revises sleeve pipe full length, can hold the drill bit of supporting operation with it and pass through, and remaining space is occupied by mending the core, mends the core and can insert the downthehole fixing and the occupy-place effect that is used for of former bone, realizes revising the position drilling of certain distance to the specified direction on the basis of former bone hole.
The nail hole corrector for the orthopedic surgery has the advantages of simple structure, light weight and convenient use; the problems of locking the far end of the intramedullary nail and deviating bone pore canals in other orthopedic surgeries are effectively solved, the surgery time is shortened, and the surgery effect is improved; is a bone surgery instrument which is suitable for various hospitals, in particular to a primary hospital and can be popularized.
The nail hole corrector for the orthopedic surgery has good clinical significance and practical value.

Detailed Description
The embodiment is a nail hole corrector for orthopedic surgery.
Referring to fig. 1 and 2, the nail hole corrector for orthopedic surgery in this embodiment is composed of a correction sleeve 1, a correction sleeve holding arm 2, a fixing hole 3, a correction hole 4, a complementary core 5 and a complementary core holding arm 6, wherein the correction sleeve 1 is fixedly connected with the correction sleeve holding arm 2, the complementary core 5 is connected with the complementary core holding arm 6, and the complementary core 5 is located in the correction sleeve 1 and is installed in cooperation with the correction sleeve 1. The correction sleeve 1 is in an elliptic cylindrical shape, a guide hole which is 8-shaped along the direction of a longitudinal axis is arranged in the center of the cross section to form a fixed hole channel 3 and a correction hole channel 4, two circle centers of the guide hole are 2mm, 3mm and 4mm away, the diameter of the guide hole is 4mm, the guide hole penetrates through the total length of the correction sleeve, a drill bit with the diameter of 4mm can be accommodated and passes through, the rest space is occupied by a supplement core, the supplement core prevents the drill bit from sliding into an original bone hole, and the newly drilled bone hole is enabled to move for a certain distance in the appointed direction. The upper end part of the correction sleeve 1 is fixedly provided with a correction sleeve holding arm 2 along the direction of the longitudinal axis of the ellipse, so that the correction sleeve can be held conveniently.
