Abstract

The utility model is related to a kind of Medical absorbable magnesium alloy nail, including magnesium alloy threaded bone rivet nut and the head of a nail, bone cement chamber is provided with magnesium alloy type thread bone nail body, some overfolw holes communicated with bone cement chamber are evenly equipped with magnesium alloy threaded bone rivet nut, 2 hand-holes communicated with bone cement chamber are evenly equipped with head of a nail end face outside, chamfered teeth is provided with head of a nail inner side end, chamfered teeth screws out direction and is obliquely installed along magnesium alloy threaded bone rivet nut;The utility model is after magnesium alloy threaded bone rivet nut is implanted into, the chamfered teeth of head of a nail inner side end produces larger frictional force with bone face, prevent nail from releasing, bone cement is injected by from hand-hole, bone cement is spilt into around nail behind chamber through hand-hole, bone cement from overfolw hole, immediately bone grafting, nail and bone tissue can well be fixed, further prevents nail from releasing.

Description

A kind of Medical absorbable magnesium alloy nail
Technical field
The utility model is related to biomedical devices field, specifically a kind of Medical absorbable magnesium alloy nail.
Background technology
Magnesium alloy is a kind of implantation material absorbable in vivo, compared with existing absorbable material, with more preferably mechanical property Energy and biocompatibility.Compared with bioactivity titanium alloy, magnesium alloy has beneficial biological absorbable performance, therefore, magnesium is closed Gold is made magnesium alloy implant devices as degradable metal material, particularly in the bone internal fixation implantation instrument of bone tissue reparation Tool has great advantage, and magnesium alloy has good medical safety basis as biological medical degradable absorbing material.But, it is existing There is the nail of technology, be fixed only by external screw thread, in use, releasing easily occurs in nail, and is brought to patient Great pain, in addition, existing nail is after the implantation, it is impossible to convenient to bone cement is injected around it, brings not small to doctor Difficulty.
Utility model content
It is a kind of Medical absorbable magnesium alloy nail that the utility model is to be provided.
In order to solve the above technical problems, the utility model provides following technical scheme:A kind of Medical absorbable magnesium alloy bone Nail, including magnesium alloy threaded bone rivet nut and the head of a nail, are provided with bone cement chamber, magnesium alloy type thread bone nail in magnesium alloy type thread bone nail body Some overfolw holes communicated with bone cement chamber are evenly equipped with body, 2 are evenly equipped with head of a nail end face outside and are communicated with bone cement chamber Hand-hole, is provided with chamfered teeth on head of a nail inner side end, chamfered teeth screws out direction and is obliquely installed along magnesium alloy threaded bone rivet nut.
The scheme for further optimizing, the head of a nail cross sectional shape is positive triangle, square, regular pentagon or positive six side Shape.
The utility model has an advantageous effect in that compared with prior art:The utility model passes through magnesium alloy type thread bone nail After body implantation, chamfered teeth and the bone face of head of a nail inner side end produce larger frictional force, prevent nail from releasing, and are noted by from hand-hole Enter bone cement, bone cement is spilt into around nail behind chamber through hand-hole, bone cement from overfolw hole, can immediately to bone grafting, nail and Bone tissue is fixed well, further prevents nail from releasing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the overlooking the structure diagram when head of a nail is regular pentagon.
In figure marked as:1- magnesium alloy threaded bones rivet nut, 101- bone cements chamber, 102- overfolw holes, the 2- heads of a nail, 201- injections Hole, 21- chamfered teeths.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain The utility model, is not used to limit the utility model.
In description of the present utility model, it is to be understood that term " longitudinal direction ", " transverse direction ", " on ", D score, " preceding ", " afterwards ", the orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outward " be based on Orientation shown in the drawings or position relationship, are for only for ease of description the utility model, rather than the dress for indicating or implying meaning Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model Limitation.
Additionally, term " first ", " second " are only used for describing purpose, and it is not intended that indicating or implying signified relatively heavy The property wanted implies the technical characteristic quantity indicated by indicating.Thus, define " first ", the feature of " second " can express or Person implicitly includes at least one this feature.In description of the present utility model, " multiple " is meant that at least two, such as two It is individual, three etc., unless otherwise expressly limited specifically.
Knowable to reference picture, a kind of Medical absorbable magnesium alloy nail, including magnesium alloy threaded bone rivet nut 1 and the head of a nail 2, magnesium conjunction Bone cement chamber 101 is provided with golden type thread bone nail body 1, is evenly equipped with magnesium alloy threaded bone rivet nut 1 some with the phase of bone cement chamber 101 Logical overfolw hole 102, is evenly equipped with 2 hand-holes 201 communicated with bone cement chamber 101, the inner side of the head of a nail 2 in the end face outside of the head of a nail 2 Chamfered teeth 21 is provided with end face, chamfered teeth 21 screws out direction and is obliquely installed along magnesium alloy threaded bone rivet nut 1.
The utility model entangles the head of a nail 2 by aiding in kit, and the rotation head of a nail 2 drives magnesium alloy threaded bone rivet nut 1 to plant Enter sclerotin, chamfered teeth 21 and the bone face of the inner side end of the head of a nail 2 produce larger frictional force, prevent nail from releasing, by from hand-hole 201 injection bone cements, bone cement is spilt into around nail behind hand-hole 201, bone cement chamber 101 from overfolw hole 102, can be immediately Bone grafting, nail and bone tissue are fixed well, further prevents nail from releasing.
In embodiment, the cross sectional shape of the head of a nail 2 is positive triangle, square, regular pentagon or regular hexagon.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
