Embodiment Construction
[0024] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the protection scope of the present invention should not be limited thereby.
[0025] The device for measuring the clamping force of the jaws of non-injury hemostats according to the present invention comprises: a base, a jaw hinge hole positioning mechanism, a jaw positioning and force measuring mechanism, and a ring finger ring force applying and positioning mechanism.
[0026] The main part of the base is a thick plate structure with a dovetail groove on its upper surface, and its front side and rear side are respectively fixed with a front riser and a rear riser. The middle part fixes the positioning mechanism of the jaw hinge hole by means of threaded connection. The lower end of the jaw positioning and force measuring mechanism is designed as a dovetail shape. The dovetail can slide back and forth in ...

The invention discloses a device for measuring the jaw clamping force of atraumatic hemostatic forceps in the technical field of medical machinery detection. The device comprises a base, a jaw hinge hole positioning mechanism, a jaw positioning and force measuring mechanism and a finger ring force application and positioning mechanism, wherein the jaw hinge hole positioning mechanism is fixed on the base; the jaw positioning and force measuring mechanism has three degrees of freedom, namely front and back movement, up and down movement and left and right movement, a force measuring sensor on the jaw positioning and force measuring mechanism is directly contacted with the jaw to be detected, so that positioning to a force point to be detected on the jaw of the hemostatic forceps and positive pressure measurement can be conveniently realized; and the finger ring force application and positioning mechanism has two degrees of freedom, namely front and back movement and left and right movement, and a positioning pin on the finger ring force application and positioning mechanism is directly contacted with the inner wall of the finger ring on the handle part of the hemostatic forceps, sothat positioning and force application of the finger ring can be realized conveniently. By adopting the device for measuring the jaw clamping force of the atraumatic hemostatic forceps, the jaw clamping force of the atraumatic hemostatic forceps of various types can be accurately measured.
Description
technical field [0001] The invention relates to a device in the technical field of medical device detection, in particular to a device for measuring the clamping force of the jaws of a non-invasive hemostat. Background technique [0002] In the clinical application of hospital surgery, hemostatic clamp is a commonly used medical device. During the operation, when the jaws of the hemostat are clamped from the open state to the closed state, the clamping force between the two jaws is a process of gradually increasing from zero. The magnitude of the clamping force is directly related to the degree of deformation of the pliers handle. [0003] In the early stage of the clamping process, the number of buckles at the end of the pliers handle is less, the degree of deformation of the pliers handle is smaller, and the clamping force between the two jaws is also smaller. As the number of teeth at the end of the pliers handles gradually increases, the degree of deformation of the tw...
