Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly relates to a drilling guide. Background Art
[0002] When fractures occur in parts such as the greater trochanter of the human femur for various reasons, during surgery, a drill bit is often used to drill a hole in the femoral neck from the outside of the upper end of the femur, and then a lag screw is driven in for fixation. How to accurately drive the drill bit into the femoral neck in one go is a worldwide problem. There are many existing femoral neck drilling positioning devices. For example, the positioner produced by "AO" in Switzerland has a through hole for inserting a drill sleeve machined on the base body. During drilling, the head of the drill sleeve abuts against the greater trochanter, and the drill bit extends from the guiding hole of the drill sleeve and then drills into the greater trochanter and the femoral neck. The entire drilling process is basically carried out based on the experience of surgeons, and there is a certain blindness in drilling. The phenomena of drilling deviation or drilling failure often occur, which aggravates the patient's injury and affects the surgical quality.
[0003] Currently, the guiding devices studied in China are all fixed guiding devices. Once an incorrect placement occurs during the operation, it cannot be adjusted. And due to the anatomical differences of each person, the guiding device needs to be individually printed for each person, wasting costs.
[0004] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve it.
[0005] The present invention discloses a dental implant positioning device for a surgical robot, which overcomes the above defects. Summary of the Invention
[0006] The present invention provides a drilling guide, which overcomes the defects in the prior art.
[0007] A drilling guide includes a main body, a slider and a guide sleeve. The slider is slidably arranged with the main body, and the guide sleeve is slidably arranged with the main body and the slider respectively. The guide sleeve is used to guide a Kirschner wire, and after the Kirschner wire is driven in, a hollow lag screw is driven in through the guidance of the Kirschner wire.
[0008] Further, the main body is provided with a first guiding hole that penetrates through the front and back, and sliding grooves are respectively arranged on the upper and lower sides of the first guiding hole. The slider is slidably arranged with the sliding grooves.
[0009] Further, the slider is provided with a parallel guiding slider, an angular guiding slider A and an angular guiding slider B.
[0010] Further, the parallel guiding slider is provided with a plurality of second guiding holes A that penetrate through the front and back, and the second guiding holes A are arranged parallel to the first guiding hole.
[0011] Further, the angle guiding slider A is provided with a plurality of second guiding holes B penetrating through from front to back. The axis of the second guiding hole B has an angle with the axis of the first guiding hole, and the angle of each second guiding hole B relative to the axis of the first guiding hole is different. At the same time, the angle guiding slider A is only used for surgical plans where both the nail insertion point and the end point are on one side of the axis of the first guiding hole.
[0012] Further, the angle guiding slider B is provided with a plurality of second guiding holes C penetrating through from front to back. The axis of the second guiding hole C has an angle with the axis of the first guiding hole, and there is a distance in the left - right direction between the axis of the second guiding hole C and the axis of the first guiding hole. At the same time, the angle guiding slider B is only used for surgical plans where the nail insertion point and the end point are on both sides of the axis of the first guiding hole respectively.
[0013] Further, there are scale lines on the front of the main body at a distance relative to the axis of the first guiding hole. On the front of the angle guiding slider A and the angle guiding slider B, there are respectively an indicating arrow and the angle values of each guiding hole. Moving the slider can make the tip of the arrow align with any one of the scale lines.
[0014] Further, the guide sleeve is provided with a first guide sleeve and a second guide sleeve. The first guide sleeve is slidably matched with the first guiding hole. The first guide sleeve is provided with a step for positioning the distance between the main body and the bone. The second guide sleeve is applicable to the second guiding hole A, the second guiding hole B, and the second guiding hole C.
[0015] Beneficial effects: During the surgical process of the present invention, after the first Kirschner wire is inserted through the first guide sleeve, the main body can be rotated by an arbitrary angle along the first Kirschner wire. Through the smooth movement of the parallel guiding slider in the sliding groove, the function of arbitrarily adjusting the drilling position of the second Kirschner wire introduced by the second guide sleeve can be realized. Especially through the smooth movement of the angle guiding slider A and the angle guiding slider B in the sliding groove, not only can the function of separately adjusting the drilling position of the second Kirschner wire and separately adjusting the drilling angle of the second Kirschner wire be realized, but also the function of selecting multiple drilling angles at an arbitrarily selected nail insertion point position of the second Kirschner wire can be completed, and the function of arbitrarily selecting the nail insertion point position for drilling after selecting the drilling angle of the second Kirschner wire can be realized, that is, the angle and position of the drilling of the second Kirschner wire can be adjusted simultaneously. It facilitates the design of surgical plans, improves the stability of the surgical process, and has the advantages of simple structure, long service life, simple operation and control, easy large - scale manufacturing, and wide application range.
