Problems solved by technology

The traditional sternal hemostasis method in cardiac surgery is to directly apply bone wax on the sternal section. Because the bone section is sharp, it is easy to stab the operator and cause unnecessary secondary pollution. At the same time, direct application is likely to cause uneven application and lead to hemostatic effect not ideal

Embodiment Construction

[0020] Such as figure 1 As shown, the bone wax smear gun according to the embodiment of the present invention includes a gun head, a gun body and an injection device. Among them, the gun head includes a spray head 11 and a gun head pipe 12. The spray head 11 and the gun head pipe 12 are connected by a rotating orienting joint 13. The width of the spray head 11 can be divided into different models according to the width of the patient's sternum. The operator can choose the appropriate one according to his own judgment. The width of the nozzle is conducive to the even application of bone wax. The shape of the nozzle 11 can be designed according to the actual situation, and the nozzle of the embodiment of the present invention is a duckbill shape.

[0021] A fixed button can be arranged on the side of the rotation-orientation joint 13. When the button is rotated in one direction, the rotation-orientation joint 13 is fixed; when it is rotated in another direction, the rotation-or...

Abstract

The invention discloses a bone wax smearing gun. The gun comprises a gun head for smearing bone wax, a gun body connected with a gun head pipeline and used for storing the bone wax and a push injection device for injecting the bone wax; the gun head comprises a spray head and the gun head pipeline, the spray head is connected with the gun head pipeline through a rotating directional joint, and therotating directional joint can change the angle of the spray head; the gun body is formed by detachably connecting a first gun body part and a second gun body part; the push injection device comprises a push injection piston, a push injection rod and a handle, one end of the push injection rod is connected with the push injection piston, and the other end of the push injection rod is connected with the handle. According to the bone wax smearing gun of the technical scheme, spray head smearing is adopted for replacing conventional finger smearing, the infection caused when the fingers are scratched is avoided, and the hemostatic effect is improved at the same time.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bone wax smear gun. Background technique [0002] With the continuous development of cardiac surgery today, surgical methods are becoming more and more diverse, but sternal splitting is still one of the key steps in the operation. , hemostasis becomes the biggest difficulty in this step. The traditional sternal hemostasis method in cardiac surgery is to directly apply bone wax on the sternal section. Because the bone section is sharp, it is easy to stab the operator and cause unnecessary secondary pollution. At the same time, direct application is likely to cause uneven application and lead to hemostatic effect Not ideal. Contents of the invention [0003] In view of the defects in the prior art, the technical problem solved by the technical solution of the present invention is to provide a device for applying bone wax, which can prevent the operator from directly touchin...
