Description

Minimally invasive drilling guide

This creation relates to a drilling guide used in minimally invasive surgery, especially a minimally invasive method that can be used to stabilize a hole in the bone when a bone plate is used to treat a fracture, so that the bone plate can fix the bone plate to the broken bone. Drilling guide.

The so-called fracture refers to the damage to the integrity and continuity of bone tissue, which is a common accidental injury. Because of the long healing time of the fracture, once neglected, it is easy to cause wound infection, poor healing of the affected area or muscle atrophy. Sequelae.

The common clinical pathological fractures are caused by abnormal or pathological changes in the bone itself, such as osteoporosis or bone deterioration due to the spread of cancer cells; pressure fractures or fatigue fractures are common For sports players or dancers.

Fracture fixation methods and bone choices change with the advancement of medical technology. Among them, bone plate bone nails are still the most commonly used internal fixation to treat fractures, especially in comminuted fractures, fractures with osteoporosis, and near Fractures at joints, etc., generally require the assistance of steel such as bone plates and bone nails to accelerate fracture healing.

When using a bone plate bone nail to treat a fracture, it is necessary to first drill holes in the fractured two fractured bones, and then use the bone nail to lock the bone plate between the two fractured bones as a fixed fractured bone. However, when drilling holes on broken bones, the holes drilled on the two broken bones must be parallel, so that the bone plate can be used to fix the bone plate on the two broken bones smoothly. The drilled holes are not parallel, which will cause the bone plate not to be locked, or an angle will be formed between the broken bones after the locking, which will not be able to smoothly join.

However, the current drilling guide used to assist the drilling, which is used to guide the perforation of the drill bit, because when the drill bit is drilled, it is necessary to provide a space for the outflow of blood and bone debris, so the hole diameter will be smaller than the outer diameter of the drill bit. Slightly larger, but because the thickness of the drilling guide is thin, the height of the perforation is not enough to guide the drill into a vertical perforation state, so that the hole drilled by the drill guided through the drilling guide is still Angle deviations may occur, resulting in a situation where drilling must be re-drilled.

From the above, there are still quite a few problems with the current drilling guides. Therefore, in view of the above problems, the creator of this case was eager to improve and innovate. After years of painstaking research, he finally successfully developed this microcomputer. Create a drilling guide.

In order to solve the above-mentioned problems of the prior art, one of the objectives of the present invention is to provide a minimally invasive drilling guide that can help stabilize the drill and avoid shifting during drilling.

To achieve the above purpose, the minimally invasive drill guide provided by this creation mainly includes a grip, at least one end of which is an operating end, and the other end of the grip is a holding end or another operating end.

Wherein, the operating end is provided with a perforation, a plurality of supporting legs are provided at the periphery of the bottom of the operating end, and a guide portion extending toward the top surface of the operating end is provided above the perforation, and a guide portion is provided on the guide portion. Perforated communicating guide holes.

In addition, the bottom of the operating end is provided with a guide groove that runs through any two opposite sides of the operating end and passes through the bottom of the perforation. Through the setting of the guide groove, bone debris and blood water generated during drilling can flow out of the guide groove.

The following will describe specific embodiments to illustrate the implementation of this creation, but it is not intended to limit the scope of protection of this creation.

Please refer to FIGS. 1-2. The minimally invasive drill guide provided by this creation mainly includes a grip 1, one end of the grip 1 is an operating end 2, and the other end of the grip 1 is opposite to the operating end 2. To hold the end 11, the operation end 2 is a flat block. A hole 21 is formed in the middle of the operation end 2 and penetrates the top surface and the bottom surface of the operation portion 2. The bottom edge of the operation end 2 is provided with a plurality of supporting legs 22. The bottom of the operating end 2 is provided with a guide groove 23 penetrating through any two opposite sides of the operating end 2 and passing through the bottom of the perforation 21. In addition, the operating end 2 is provided above the perforation 21 with a direction facing the top surface of the operating end 2. The extended columnar guide portion 3 is provided with a guide hole 31 having the same hole diameter as the perforation hole 21 in the middle of the guide portion 3.

Please refer to Figures 3 ~ 5. When using the minimally invasive drill guide provided by this creation, place the bone plate 4 on the bone to be drilled (not shown), and make the hole 41 on the bone plate 4 Align the position to be drilled, then hold the holding end 11 of the minimally invasive drilling guide of this creation, and then press the bottom of the operation end 2 against the upper surface of the bone plate 4, and push the bottom of the operation end 2 through The supporting feet 22 rest on the outer edge of the bone plate, and align the perforation 21 with the hole 41 on the bone plate 4, and then pass the drill 5 through the perforation 21 and the bone plate 4 through the guide hole 31 of the guide 3 Hole 41 to drill a bone with a drill 5.

From the above, the minimally invasive drilling guide provided by this creation is to add a guide 3 with a guide hole 31 to the conventional drilling guide, thereby increasing the guided distance of the drill 5 , So that the drill bit 5 can drill more vertically, reduce the deflection angle of the drill bit 5, and then control the angle and position of the drill hole to avoid the holes drilled on the two sides of the broken bone are not parallel, resulting in the bone plate 4 cannot be fixed Broken bones require re-drilling.

The above detailed description is a specific description of one of the feasible embodiments of this creation, but this embodiment is not intended to limit the scope of the patent for this creation. Any equivalent implementation or change that does not depart from the spirit of this creation technique should be included in Within the scope of the patent in this case.
