Embodiment Construction

[0021] 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.

[0022] The invention simplifies the problem of the clamping force of the jaws of the non-damaging hemostat to the positive pressure at the jaws of a single forceps arm to deal with. The device for measuring the clamping force of the jaws of non-injury hemostats based on the present invention consists of four parts: a base, a jaw hinge hole positioning mechanism, a jaw positioning and force measuring mechanism, and a finger ring applying force and positioning mechanism. The jaw hinge hole positioning mechanism is fixed on the base, and the pins on it are used for positioning the jaw hinge hole of the non-injury hemostat. The jaw positioning and force measuring mechanism has three degrees of freedom of forward and backward movement...

Abstract

The invention discloses a clamping force control oriented method for measuring the jaw clamping force of atraumatic hemostatic forceps. The method comprises the following steps: 1, preparing a check bar to be detected; 2, determining the relationship between the jaw gap and the engagement number of buckles at the tail end of a forceps handle; 3, primarily adjusting the jaw positioning and force measuring mechanism of an atraumatic hemostatic forceps jaw clamping force measurement device; 4, adjusting a jaw hinge hole positioning mechanism of the measuring device and positioning the jaw hinge hole; and 5, adjusting a finger ring force application and positioning mechanism of the measuring device, fine tuning the jaw positioning and force measuring mechanism of the measuring device, and reading positive pressure data of the jaw. By adopting the method, the jaw clamping force of the mature atraumatic hemostatic forceps of various types can be accurately measured, and the measurement dataare provided to clinical doctors, so that the doctors can reasonably control the jaw clamping force of the atraumatic hemostatic forceps in surgery.

Description

technical field [0001] The invention relates to the technical field of medical device detection, in particular to a method for measuring the clamping force of a non-invasive hemostat jaw clamping force control. 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...
