Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of femoral neck fractures, and more specifically, to a percutaneous internal fixation guide plate device for femoral neck fractures in orthopedics Background Art
[0002] Clinically, for elderly patients with femoral neck fractures, especially those with femoral neck fractures at an advanced age, joint replacement is usually chosen. The younger the patient's age, the more preferred is closed reduction and internal fixation of the fracture. Especially for middle-aged and young patients with femoral neck fractures, the surgical method usually selects closed reduction + cannulated screw internal fixation. For this surgery, the patient needs to lie flat on the operating table, and the fracture ends are reduced under fluoroscopy on the operating table. Then, a guide pin is drilled into the lateral greater trochanter. After the position of the guide pin is satisfactory under fluoroscopy, the appropriate cannulated screw is measured and replaced to fix and compress the fracture ends.
[0003] After retrieval, the existing patent (publication number: CN202365911U) discloses a pin-piercing fixator for femoral neck fractures. Currently, the better method for treating femoral neck fractures is pin-piercing treatment. The pin-piercing surgery has very high requirements for the doctor's operation, especially for accurate positioning to avoid large incisions or causing bone fractures. Currently, there is no convenient and simple pin-piercing fixator that can help doctors quickly and accurately perform pin-piercing treatment for femoral neck fractures in clinical practice. The composition of this product includes: a polyhedron (1) with a trapezoidal side projection, hinges (2) are installed on both sides of the polyhedron, and a group of pin-piercing through holes (3) are provided on the polyhedron. This product is used as a medical device.
[0004] During the use of the above device, it is difficult to fix the device during the operation, and the angle cannot be adjusted freely and flexibly. At the same time, the air permeability of the device is poor, which is not conducive to the air permeability of the patient's skin during the operation. Summary of the Utility Model
[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a percutaneous internal fixation guide plate device for femoral neck fractures in orthopedics to solve the problems of difficult fixation, inability to adjust the angle, and poor air permeability.

[0007] Preferably, the needle placement guiding assembly includes a first needle placement guide, a second needle placement guide, and a third needle placement guide. The first needle placement guide is fixedly installed on the base, the second needle placement guide is fixedly installed on the base, the second needle placement guide is disposed on one side of the first needle placement guide, the third needle placement guide is fixedly installed on the base, and the third needle placement guide is disposed at the bottom of the first needle placement guide.
[0008] Preferably, the first needle placement guide includes a needle placement guide body and a guiding round hole. The needle placement guide body is fixedly installed on the base, and the guiding round hole is opened on the needle placement guide body.
[0009] Preferably, the marking assembly includes a first marking position and a second marking position. The first marking position is fixedly installed on the upper side of the base, and the second marking position is fixedly installed in the middle of the base.
[0010] Preferably, the first needle placement guide, the second needle placement guide, and the third needle placement guide have the same structure, and the first needle placement guide, the second needle placement guide, and the third needle placement guide are inclined and installed on the base.
[0011] Preferably, there are five groups of the guiding round holes, and the five groups of guiding round holes are equidistantly opened on the needle placement guide body.
[0012] Preferably, the base is arranged in a honeycomb shape, and triangular holes are arrayed on the base.
[0013] Preferably, the first marking position and the second marking position are made of a breathable material, and the patient's name can be inscribed on the outer surfaces of the first marking position and the second marking position.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] After routine surgical disinfection and draping, the position of the greater trochanter is located on the body surface. Under fluoroscopy, the three first needle placement guides, second needle placement guides, and third needle placement guides placed on the base outside the greater trochanter are adjusted to approximately appropriate positions. One of the guiding round holes of one of the first needle placement guides is selected to drill a guide pin through the skin. After adjusting the anterior inclination angle appropriately, a Kirschner wire is drilled through the skin through the transverse positioning guiding hole to fix the guide plate. The specific position of the Kirschner wire passes under the lesser trochanter. In the holes opened in the remaining two second needle placement guides and third needle placement guides, under fluoroscopy, the positions of the three guide pins are simultaneously finely adjusted through the subdivision guiding holes until satisfactory. The lengths of the three guide pins drilled in are pre-calculated based on the remaining lengths of the guide pins. After removing the guide plate, hollow screws of corresponding lengths are selected and screwed into the skin one by one. With the above structure, the effects of facilitating positioning, convenient position adjustment, and breathability are achieved. BRIEF DESCRIPTION OF THE DRAWINGS
