Abstract
The utility model discloses a medical bone nail, comprising a nail body and a nail cap, wherein the nail cap is fixed at the end of the nail body; a connecting surface with a round table structure is arranged between the nail cap and the nail body; and the nail cap and the nail body are respectively provided with threads. As the nail cap and the nail body are respectively provided with the threads, the firmness of the bone plate for the patients in the bone healing process is ensured, the nail can be easily screwed out by the bone nail extractor through the firm connection of the threads and the nail cap and the bone nail when the bone nail is screwed out, and the patients cannot feel discomfortable due to sharp edge of the bone nail in movement as the combination of the round table-shaped connecting surface and the patient muscle is smooth.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to the synthetism nail that uses in a kind of fracture operation process.
Background technology
For the comparatively serious patient of fracture, hospital generally all can take to utilize blade plate and synthetism nail that patient's fracture is fixed, and when adopting this Therapeutic Method, the synthetism nail need be squeezed into patient's inside bone, to guarantee the good stationarity of blade plate.But the outer surface of existing synthetism nail is smoother, and in the wounded's daily routines, the synthetism nail occurs loosening easily, is unfavorable for that blade plate is secular fixing; The nail body of some synthetism nail is screwed, in the agglutination of bone, bone and its cells can constantly grow and extend in the slit of nail body screw thread, make synthetism nail and bone binding ratio tightr, and the head of a nail of this class synthetism nail is a smoother, when the back-out of synthetism nail,, be unfavorable for saving the time of operation because combining closely of bone and nail body makes the back-out of synthetism nail relatively more difficult.
The utility model content
Technical problem to be solved in the utility model provides a kind of good fixing effect, medical synthetism nail simple in structure.
For solving the problems of the technologies described above, the technical solution of the utility model is: medical synthetism nail, comprise the nail body and the head of a nail that is fixed on described nail end of body, be provided with the joint face of frustum cone structure between the described head of a nail and the nail body, be respectively equipped with screw thread on the described head of a nail, nail body and the joint face.
As a kind of improvement, the direction of rotation of the described screw thread on the described head of a nail, nail body and the joint face is consistent.
As further improvement, the described head of a nail is the one injection structure with the nail body.
After having adopted technique scheme, medical synthetism nail comprises the nail body and the head of a nail that is fixed on described nail end of body, is provided with the joint face of frustum cone structure between the described head of a nail and the nail body, is respectively equipped with screw thread on the described head of a nail and the nail body.The beneficial effects of the utility model are: be respectively equipped with screw thread on the nail body of synthetism nail and the head of a nail, both guaranteed the fastness of patient's blade plate in the synthetism agglutination, again can be when screwing out the synthetism nail, make synthetism nail device for screwing out can utilize screw thread and solid the combining of synthetism stickfast on the head of a nail, be relatively easy to its back-out, and the joint face of truncated cone-shaped combines smootherly with patient's muscle, makes the patient aprowl can be because of the head of a nail edge of synthetism nail too not sharp and do not feel well should.
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment.
The specific embodiment
As shown in drawings, medical synthetism nail, comprise the nail body 1 and the head of a nail 2 that is fixed on described nail body 1 end, be provided with the joint face 4 of frustum cone structure between the described head of a nail 2 and the nail body 1, arcual joint face 4 combines smoother with patient's muscle, and also bigger with the contact surface of patient's muscle, make the patient aprowl can be too not sharp and do not feel well should because of the head of a nail 2 edges of synthetism nail.
Be respectively equipped with screw thread 3 on the described head of a nail 2 of present embodiment, nail body 1 and the joint face 4, and the direction of rotation of the described screw thread 3 on the described head of a nail 2, nail body 1 and the joint face 4 is consistent, screw thread 3 on the nail body 1 is in patient's bone-setting treatment process, osteocyte can be combined closely with nail body 1, it is loosening to prevent that the synthetism nail from occurring, to guarantee the fastness of blade plate; And the screw thread 3 on the head of a nail 2 is the frictional force that can increase in the back-out process between synthetism nail and the synthetism nail device for screwing out contact surface for the ease of following closely combining of device for screwing out with synthetism, synthetism being followed closely, and makes things convenient for the synthetism nail to screw out apace.
The described head of a nail 2 in this utility model is the one injection structure with nail body 1, and is simple in structure, easy to use.
