Low-heat precise reduction bone needle

Abstract

The utility model relates to a low heat accurate reduction bone needle, its main body structure comprises a needle tip part, a needle body and a needle tail part, the needle tip part is provided with a three-blade structure, each blade part is provided with a front knife face, a cutting edge, a first rear knife face and a second rear knife face, a lengthened spiral groove structure is arranged between every two blade parts, the needle body is marked with scale marks, and the needle tail part is provided with a first spiral groove and a second spiral groove. One end of the needle body is connected with the needle tip part, and the other end of the needle body is connected with the needle tail part. Due to the design of the lengthened spiral groove, bone scraps can be completely removed, heat is effectively reduced, and secondary damage caused by too much bone scraps and too high heat is avoided; the scale line design of the needle body assists a doctor in accurately determining the using length and accurately controlling the bone drilling depth in the operation process, and the bone drilling needle has the advantages of being low in heat, high in efficiency, accurate in positioning, accurate in resetting, convenient to operate, capable of preventing osteonecrosis caused by high temperature, avoiding secondary damage to bones caused by the phenomena such as blade breaking and the like and the like.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a low-heat precise reset bone needle. BACKGROUND

[0002] In clinical medical treatment, it is very common to use a bone needle for bone reset operation during orthopedic surgery, and the bone needles on the market are mostly three-edge needle tips, but the efficiency of the bone needle of this type into the bone is low, the excess bone chips cannot be discharged, and high heat generated during bone drilling can cause secondary injury.

[0003] To solve the above-mentioned problems, the utility model patent "Spiral groove three-blade needle for orthopedics (Patent No. 202122693921.9)" has been obtained, which has good feedback effect through clinical test, but there are still problems such as incomplete removal of bone chips and inaccurate determination of bone drilling depth during use, which need to be improved.

[0004] In summary, the bone needle on the market still cannot meet the requirements of high efficiency, accurate positioning, low heat and good chip removal in use. UTILITY MODEL CONTENTS

[0005] To solve the above-mentioned problems, the utility model provides a low-heat precise reset bone needle, which comprises a needle tip, a needle body and a needle tail, the needle tip is provided with three cutting edges, a lengthened spiral groove is arranged between every two cutting edges, one end of the needle body is connected with the needle tip, and the other end is connected with the needle tail.

[0006] Preferably, the needle body is provided with a scale line.

[0007] The utility model has the advantages that the low-heat precise reset bone needle provided by the utility model can ensure complete and smooth removal of bone chips, effectively reduce heat, avoid secondary injury caused by excessive bone chips and high heat, accurately determine the use length of the needle body during the operation process, ensure the drilling depth, has the advantages of low heat, high efficiency, accurate positioning, precise reset, easy operation, prevention of bone necrosis caused by high temperature, avoidance of secondary injury to the bone caused by phenomena such as broken blade, and the like.

[0011] In order to further understand the innovative content of the utility model, the utility model will be described in detail below in combination with specific embodiments.

[0012] EMBODIMENT

[0013] As Figure 1 shown, the utility model provides a kind of low-calorie accurate reset bone needle-double pointed end type, including needle tip part 1, needle body 2, needle tail part 3, in this embodiment, needle tail part 3 is set to the structure of needle tip part 1, forms double pointed end type.

[0014] The needle body 2 is provided with a scale line.

[0015] The needle tip part 1 is provided with three cutting edges 5, the right side of the cutting edge 5 is provided with rake face 6, the left side of the cutting edge 5 is sequentially provided with first relief 9 and second relief 8, and the middle of the rake face 6 of first cutting edge 5 and the second relief 8 of second cutting edge 10 is provided with lengthened helical groove 7.

[0016] The needle tail part 3 can be set to the needle tip part 1 type of this embodiment, can also be set to other structures, and the involved embodiment has been described in detail in the utility model patent achievement "a helical groove three-blade needle for orthopedics (patent number: 202122693921.9)".

[0017] It is not difficult for those skilled in the art to understand that the utility model of a kind of low-calorie accurate reset bone needle includes the arbitrary combination of the utility model content and specific embodiment part of the utility model specification of the above utility model and the part shown in drawing, limited to the length and to make the specification concise, and these schemes formed by combination are not described one by one. Any modification, equivalent replacement, improvement etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
