Abstract
The utility model discloses a bone bolt for clinical operation. The utility model comprises a screw bolt and a telescopic nut. The length of the telescopic nut is one third to three fourths of the length of the screw bolt, and a coronal head is formed at the top of the telescopic nut. The bone bolt is convenient for the recovery of the illness after the fracture operation.
Description
This utility model relates to the bone fracture internal fixing device that a kind of clinical operation is used.
Fast development along with transportation, the fracture of the tibial plateau that wound causes, ankle joint fracture companion lower tibiofibula ligament separates, chi scratch joint companion down chi to scratch the isolating damage in joint more and more, cause is nearly joint and intra-articular fracture all, functional rehabilitation requires high, needs with a kind of inner fixing device that is called the bone bolt in the operation.The bone bolt was bolt, nut, gasket construction (as Fig. 1) in the past, this bone bolt is used for clinical operation, the bolt top can more or less be given prominence to outside the nut, because of the bone bolt is positioned at around the joint, soft tissue is less, during joint motion, the outer part local skin easy to wear of the outstanding nut in bolt top, cause subcutaneous cunning and skin ulceration, infection, the long-term effect of influence operation and the rehabilitation of the state of an illness become the difficult problem that the required solution of clinical orthopaedics solves.
The bolt top was positioned within the nut and the bone inner fixing device of the skin that can not wear and tear when this utility model purpose was to provide a kind of clinical operation.
Designed for achieving the above object bone bolt is made up of bolt and sleeve nut, sleeve nut's length be bolt length 1/4th to 3/4ths between, bolt can have bigger shift motion in the sleeve nut.
The telescopic pressurization bone of this utility model bolt is because its sleeve nut is longer, the shift motion of bolt in the sleeve nut is longer, therefore when clinical operation, bolt can fasteningly split bone and its top is exposed outside the sleeve nut, can not make and to the wearing and tearing of local skin, prevent skin ulceration, infection, help postoperative state of an illness rehabilitation.In addition, bolt and sleeve nut's contact surface increase, and tensile strength increases, and operation technique is simple, easy-to-use.

Be described further below in conjunction with accompanying drawing:
As can be seen from Figure 3, the bone bolt is made up of bolt 1 and sleeve nut 2, sleeve nut's 2 length be bolt 1 length 1/4th to 3/4ths between, the sleeve nut top is a crown head 3, crown diameter is greater than sleeve stack shell diameter, in conjunction with Fig. 4, Fig. 5 is provided with cross recess in nut 1 top as can be known, and sleeve nut's 2 one ends also have cross recess.
As shown in Figure 6, telescopic pressurization bone bolt also can be made up of bolt 1 ＇ and sleeve nut 2 ＇, and 1 or 2 pads 3 also can be set up in bone bolt one or both ends.
Telescopic pressurization bone bolt also can be designed to as accompanying drawing 8, bolt 1, and " be made of small one and large one two-stage nitration of diameter, it is thread segment that the less section of diameter is provided with screw thread, and thread segment length equals 1/2nd of bolt length, the sleeve nut 2 " length and thread segment equal in length.
Claims (3)
1, a kind of telescopic pressurization bone bolt, it is made up of bolt, sleeve nut, it is characterized in that: sleeve nut's length be bolt length 1/4th to 3/4ths between, the sleeve nut top forms a crown head, its crown head diameter is greater than sleeve nut's stack shell diameter.
2, telescopic according to claim 1 pressurization bone bolt, its feature is one: one or two pads also can be set up in described bone bolt two ends.
3, telescopic according to claim 1 pressurization bone bolt, its feature is one: described bolt can be designed to the two-stage nitration that diameter does not wait, and it is thread segment that the less section of diameter is provided with screw thread, described sleeve nut's length and thread segment equal in length.
