Embodiment 1

[0042] This embodiment provides an inclinometer 100 for orthopedic surgery, which includes an angle measurement component and a guide component. The guide assembly comprises an introducer needle 11 arranged for insertion into a guide needle sleeve. The angle measurement assembly includes a protractor mechanism and a plumb mechanism, the protractor mechanism and the guide pin 11 are connected to each other, the plumb mechanism includes a plumb line 102 and a plumb body 103, and the two ends of the plumb line 102 are respectively connected to the guide pin 11 and the plumb body 103 .

[0043] It is worth noting that the guide needle 11 of the inclinometer 100 for orthopedic surgery can be inserted into the guide needle sleeve as a guide medium to determine the position of the guide needle; the protractor mechanism and the plumb mechanism can directly measure the inclination of the guide needle. Angle, to get accurate tilt angle value, the structure design is reasonable and prac...

Embodiment 2

[0057] In the first embodiment, the guide needle 11 is a solid needle structure, so as to be inserted into the guide needle sleeve 114 . However, in Embodiment 2, the structure type of the guide assembly is different. Please refer to figure 2 , the guide needle 11 in the guide assembly of the present embodiment is a hollow structure, which has a hollow groove 113 and a sleeve 114, and the structural design of the hollow groove 113 can make the orthopedic surgery inclinometer 100 directly to the steel guide inserted into the guide. The needle is used for angular measurement to improve the overall applicability of the device.

[0058] Another object of the present invention is to provide a method for using the inclinometer 100 for orthopedic surgery, which includes the following steps:

[0059] Insert the guide pin 11 of the inclinometer 100 for orthopedic surgery into the guide pin sleeve;

[0060] Adjust the first inclination angle of the sight so that the first inclinatio...

Abstract

The invention provides a dip angle measurer for orthopedic surgery and a using method, and relates to the technical field of medical instruments. The inclination angle measurer for the orthopedic surgery comprises an angle measuring assembly and a guiding assembly. The guide assembly includes a guide needle configured for insertion into a guide needle sleeve. The angle measuring assembly comprises a protractor mechanism and a plumb mechanism, the protractor mechanism is connected with the guide needle, the plumb mechanism comprises a plumb line and a plumb body, and the two ends of the plumb line are connected to the guide needle and the plumb body respectively. The guide needle of the inclination angle measurer for the orthopedic surgery can be used as a guide medium to be inserted into the guide needle sleeve so as to determine the position of the guide needle; the protractor mechanism and the plumb mechanism can directly measure the inclination angle of the guide steel needle, and an accurate inclination angle value is obtained. According to the use method, on the premise that the operation quality is guaranteed, the anesthesia and operation time can be obviously shortened, bleeding in the operation and the use of anesthetic are reduced, X-ray exposure is reduced, and complications are reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an inclinometer for orthopedic surgery and a method for using it. Background technique [0002] Intertrochanteric fracture, also known as intertrochanteric fracture, is the most common hip fracture in clinical practice. It occurs mostly in elderly patients, accounting for 3.51% of all fractures in the whole body. It has a high death and disability rate, and the mortality rate within one year may exceed 20%, known as "the last fracture in life". With the prolongation of life expectancy of our population and the arrival of an aging society, the incidence rate has also increased. At present, it is considered that early surgical treatment is the preferred method, and the technique of proximal femoral intramedullary nailing is the "gold standard" of current treatment. A skilled orthopedic surgeon can complete the operation within half an hour, but many operations may not...
