Abstract

The utility model provides a limiting metal spicule, which comprises a tail part, a rod part and a blade part which are connected in sequence, and also comprises a butterfly buckle, wherein two grooves are symmetrically arranged on the two sides of the rod part, and the butterfly buckle is matched with the two grooves and is used for limiting and fixing bone blocks; the tail part is a tip end and is used for the butterfly buckle to penetrate through. The advantages are that: on one hand, the limiting metal spicule with the structure designed by the application is simpler in manufacturing process, reduces material waste in the processing process, reduces processing difficulty, and plays a role in positioning and reinforcing bone blocks; on the other hand, the limiting type metal spicule can replace the application of the original limiting type metal spicule in bone block fixation and can also be used as a common spicule, and the application range of the spicule is further expanded.

Description

Limiting metal spicule

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a restriction type metal spicule.

Background

The metal spicule is suitable for partial implantation into a human body for traction when the limb fracture is reduced, and limb fracture fixation is carried out by matching with an external fixing support or is independently implanted for internal fixation of the limb fracture. The implantation is completed through a surgical mode, the implantation is expected to be contacted with bone tissues, muscle tissues and tendon tissues, and the structure of the product consists of a blade part, a rod part and a tail part.

According to clinical requirements, the metal spicules have various different design forms so as to meet different clinical requirements, wherein when a bone block needs to be fixed, the limiting spicules can be selected for fixing. The rod part of the restriction type spicule is provided with an olive-shaped bulge, and when the bone spicule of the restriction type is implanted into a human body, the bulge is contacted with muscle tissue on one side of the human body, so that the functions of positioning and reinforcing bone blocks can be achieved.

However, the conventional limited metal spicules are integrated spicules, and cannot be manufactured by welding and the like, while the olive protrusions on the spicules are processed by a longitudinal cutting method and the like, and the olive protrusions need a raw material with a larger diameter, and the rest of the material is cut off to form the spicules of the type. The bone needle of this model of processing degree of difficulty is great, and the material is extravagant more.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned technical defect and provide restriction type metal spicule, its manufacturing process is simple, practice thrift the cost, and plays the effect of location and reinforcement bone piece.

The limiting type metal spicule comprises a tail part, a rod part and a blade part which are connected in sequence, and further comprises a butterfly buckle, wherein two grooves are symmetrically formed in two sides of the rod part, and the butterfly buckle is matched with the two grooves and used for limiting and fixing bone blocks; the tail part is a tip end and is used for the butterfly buckle to penetrate through.

The tail part and the blade part have the same structure.

The two grooves are fillet grooves.

The two grooves are formed at one end close to the tail part.

The tail part, the rod part and the blade part are integrally formed.

The utility model discloses restriction type metal spicule, its advantage is: on one hand, the limiting metal spicule with the structure designed by the application is simpler in manufacturing process, the waste of materials in the processing process is reduced, and the processing difficulty is reduced; the cooperation of the butterfly buckle and the groove has larger contact area with the bone block and better positioning and reinforcing effects compared with the prior olive bulge; on the other hand, the limiting type metal spicule can replace the application of the original limiting type metal spicule in bone block fixation and can also be used as a common spicule, and the application range of the spicule is further expanded.

the tail part 1, the rod part 2, the blade part 3, the butterfly buckle 4, the groove 5 and the bone tissue 6.

Detailed Description

The present invention will be described with reference to the accompanying drawings, which are used to illustrate and explain the present invention, and are not used to limit the present invention.

The limiting type metal spicule comprises a tail part 1, a rod part 2, a blade part 3 and a butterfly buckle 4, wherein the tail part 1, the rod part 2 and the blade part 3 are connected in sequence; the tail part 1 is a pointed end and is used for the butterfly buckle 4 to penetrate through.

The tail part 1 and the blade part 3 have the same structure.

Two the groove 5 is the fillet groove to reduce stress concentration, improve spicule tensile strength.

The two grooves 5 are formed at one end close to the tail part 1, so that after the spicule is implanted into a part needing to be fixed, the butterfly buckle 4 penetrates from the tail part 1 to be matched with the two grooves 5, and the purposes of positioning and reinforcing bone blocks are achieved.

Afterbody 1 pole portion 2 cutting part 3 integrated into one piece in the manufacturing process, can select the raw and other materials of suitable width, directly leave two of symmetry at the bellied position of olive on original restriction type metal spicule groove 5 can to reduce stress concentration, more effectively guaranteed that the tensile strength of spicule satisfies the operation requirement.

The utility model discloses a realize like this:

firstly, implanting the spicule according to the using mode of a common spicule, then inserting the butterfly buckle 4 into the groove 5 from the tail part 1 of the spicule to limit and fix bone tissues 6, and finally connecting the bone tissues with an external fixing bracket to perform subsequent operation.

When the bone needle does not need to be used as a limiting bone needle, the bone needle only needs to be used according to the using method of the metal bone needle, the bone needle is implanted into a part needing to be fixed by an electric drill, and the bone needle is connected with an external fixing support after being implanted for treatment.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
