Description
[technical field]
This utility model relates to technical field of medical instruments, especially relates to a kind of extraction apparatus for head of femur.
[background technology]
Known, along with social senilization and osteoporotic development, the patient of fracture of femoral neck rises year by year, and the age is many with more than 60 years old person, because patient gets old and weak, and often with a series of chronic disease, as diabetes, coronary heart disease, hypertension, chronic tracheitis etc., long-term bed after fracture, very easily cause serious complication, as pneumonia, blood vessel embolism, cerebrovas-cularaccident, decubital ulcer etc., these complication not only affect the healing of fracture, even also can threaten the life of patient, femoral head replacement is that the optimal treatment of this patient is selected, but because femoral head bone is loose serious, current extraction apparatus for head of femur is difficult to hold resected femur head, femoral head is caused to take out difficulty, take out imperfect, thus extend Post surgery duration, simultaneously can not Measurement accuracy femoral head diameter, affect therapeutic effect.
[utility model content]
In order to overcome the deficiency in background technology, the utility model discloses a kind of extraction apparatus for head of femur, this utility model, by arranging handle and measuring device with on the sleeve of draw-in groove, reaches the capital object of quick, complete taking-up with this.
In order to realize described utility model object, this utility model adopts following technical scheme:
A kind of extraction apparatus for head of femur, comprises handle, sleeve, drilling rod, drill bit and measuring device, is provided with fixed cap in one end of sleeve, the other end of sleeve is provided with draw-in groove, and drilling rod is through fixed cap, and drilling rod one end is provided with handle, the drilling rod other end is provided with drill bit, and the lateral surface of sleeve is provided with measuring device.
Described draw-in groove is laciniation.
Described drill bit is pyramid type structure, and drill bit is provided with screw thread.
Described measuring device is made up of dip stick and connecting rod, and dip stick is connected with sleeve by connecting rod.
Owing to have employed technique scheme, this utility model has following beneficial effect:
A kind of extraction apparatus for head of femur described in the utility model, comprises handle, sleeve, drilling rod, drill bit and measuring device, by arranging handle and measuring device with on the sleeve of draw-in groove, reaches the capital object of quick, complete taking-up with this; This utility model is practical, operate fairly simple, not only can take out femoral head fast and accurately, and femoral head size can accurately be measured, reduce operation wound, hemorrhage and interference to normal acetabular bone and surrounding soft tissue, whole design have sturdy and durable, easy and simple to handle, femoral head take out complete, be beneficial to femoral head take out after diameter measurement, reduce surgical injury, the feature such as with low cost.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
In figure: 1, hands handle; 2, drilling rod; 3, fixed cap; 4, sleeve; 5, draw-in groove; 6, drill bit; 7, connecting rod; 8, dip stick.
[detailed description of the invention]
By explanation this utility model that the following examples can be detailed, open the purpose of this utility model is intended to protect all technological improvements within the scope of this utility model.
A kind of extraction apparatus for head of femur by reference to the accompanying drawings described in 1, comprise handle 1, sleeve 4, drilling rod 2, drill bit 6 and measuring device, fixed cap 3 is provided with in one end of sleeve 4, the other end of sleeve 4 is provided with draw-in groove 5, drilling rod 2 is through fixed cap 3, drilling rod 2 one end is provided with handle 1, and drilling rod 2 other end is provided with drill bit 6, and the lateral surface of sleeve 4 is provided with measuring device; Described draw-in groove 5 is laciniation; Described drill bit 6 is pyramid type structure, and drill bit 6 is provided with screw thread; Described measuring device is made up of dip stick 8 and connecting rod 7, and dip stick 8 is connected with sleeve 4 by connecting rod 7.
Implement a kind of extraction apparatus for head of femur described in the utility model, operationally, user first grasps handle 1, then the draw-in groove 5 of sleeve 4 one end is made to be inserted into fracture of femoral neck stump, fixedly secure femoral head, and then make drill bit 6 be screwed into femoral head by screwing drilling rod 2, so just can be quick by femoral head, complete taking-up, decrease operation wound simultaneously, and measuring device can accurately measure femoral head size, reduce operation wound, hemorrhage and interference to normal acetabular bone and surrounding soft tissue, whole design has sturdy and durable, easy and simple to handle, femoral head takes out complete, be beneficial to femoral head and take out rear diameter measurement, reduce surgical injury, the feature such as with low cost.
The non-detailed portion of this utility model is prior art.
