A portion of the first working piece 104 and a portion of the second working piece 105 are located in the through hole, and the portion of the first working piece 104 located in the through hole and the portion of the second working piece 105 located in the through hole are rotationally connected, the first working piece 104 and the second working piece 105 have a tendency to slide outwards of the through hole under the action of the elastic piece 110, and because the portion of the first working piece 104 located in the through hole and the portion of the second working piece 105 located in the through hole are rotationally connected, an included angle between the first working piece 104 and the second working piece 105 in the outward sliding process becomes large, and when the first working piece 104 and the second working piece 105 are controlled to slide inwards of the through hole, the included angle between the first working piece 104 and the second working piece 105 becomes small, so that an biting force is formed to treat blood clots and hematomas.
The elastic member 110 may be a spring, and the service life of the spring is long, and the precision of the spring is high, so that the use precision can be satisfied, and of course, the spring is only one embodiment of the elastic member 110, and the elastic member 110 may be another elastic member such as rubber.
The first groove 108 may be a dovetail groove, and the second groove 109 may be a dovetail groove. The dovetail grooves can enable the first working piece 104 and the second working piece 105 to be more accurate and stable in the sliding process. Of course, the dovetail groove is just one embodiment of the first groove 108 and the second groove 109, and it is also possible that the first groove 108 and the second groove 109 are provided in other shapes.
The maximum and minimum angles between the first and second working sheets 104 and 105 can be controlled by the lengths of the first and second grooves 108 and 109, and of course, the lengths of the first and second grooves 108 and 109 should be the same.
The intracranial hematoma removal hemostat further comprises a controller 112, one end of the controller 112 is connected with the joint of the first working piece 104 and the second working piece 105, and the other end of the controller 112 extends out of the handle 103 from one end of the handle 103 away from the clamping block 111. Pulling the controller 112 can make the included angle between the first working piece 104 and the second working piece 105 smaller, and after releasing the controller 112, the included angle between the first working piece 104 and the second working piece 105 becomes larger again under the action of the elastic piece 110.
Example 3
Referring to fig. 5, this embodiment also provides an intracranial hematoma removal hemostat, which is a further improvement on the technical solutions of embodiment 1 and embodiment 2, and the technical solutions described in embodiment 1 and embodiment 2 are equally applicable to this embodiment, and the disclosed technical solutions of embodiment 1 and embodiment 2 are not repeated.
Specifically, the difference between this embodiment and embodiment 1 is that the intracranial hematoma removing hemostat provided in this embodiment sets the clamping block 111 on the connecting portion 107, so that the first working piece 104 and the second working piece 105 are connected with the handle 103 through the connecting portion 107, the first working piece 104 and the second working piece 105 of the intracranial hematoma removing hemostat can rotate along with the connecting portion 107, meanwhile, the included angle between the first working piece 104 and the second working piece 105 can be changed by the controller 112, when a patient receives treatment, the intracranial condition is complex and changeable, and the intracranial hematoma removing hemostat capable of rotating can adjust the first working piece 104 and the second working piece 105 to adapt to complex and changeable conditions, so that the intracranial hematoma removing hemostat is more suitable for various occasions, and the efficiency and success rate of surgery are improved.
Example 4
Referring to fig. 6 to 8, the present embodiment provides an intracranial hematoma removal hemostatic device comprising a power source 113 and an intracranial hematoma removal hemostat as described above.
