Embodiment Construction

[0037] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0038] In one embodiment, the medical hemostatic device is provided with at least one pressure sensor, and the pressure sensor is provided at a pressure-receiving part of the medical hemostatic device. The pressure sensor is a film-type force-sensitive sensor, and the film-type force-sensitive sensor includes carbon ink and a sensing electrode, and the carbon ink is pressed and connected to the sensing electrode, so that the resistance of the sensor is connected Stress is inversely proportional.

[0039] Such as figure 1 and figure 2As shown, the medical hemostatic device clamping force detection system applied to the device described in this embodiment includes a collection and interface circuit module and a clamping force detection module. Wherein, the acquisition and interface circuit module includes a voltage divider circuit unit, a d...

Abstract

The invention relates to a medical hemostatic device, a clamping force detection system, a calibration and measurement device and a method, and belongs to the technical field of medical instruments. The medical hemostatic device is at least provided with one pressure sensor arranged on a pressed portion. Through connection between the pressure sensor and the clamping force detection system of the medical hemostatic device, a clamping detection module of the clamping force detection system of the medical hemostatic device can be adopted to obtain clamping force data of the medical hemostatic device according to pressure data obtained from the pressure sensor, so the clamping force detection system can accurately detect the clamping force of the medical hemostatic device when blood flow in blood vessels is blocked, effectively blocks the blood vessels and does not damage blood vessel walls in the surgery process, and ensures the smooth progress of a surgery and postoperative recovery of patients. The medical hemostatic device, the clamping force detection system, and the calibration and measurement device are simple in structure, low in cost, and wide in application scope, and an application mode of the calibration and measurement method is quite simple and convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to the technical field of medical hemostatic devices, and specifically refers to a medical hemostatic device, a clamping force detection system, a calibration and measurement device and a method. Background technique [0002] Surgical instruments are essential tools in surgical operations. For the measurement requirements of the clamping force, locking force, and disengagement force of medical hemostatic clips / pliers, industry standards have been proposed as early as the mid-1980s. However, due to the backward processing technology of the lip teeth of the hemostatic forceps at that time, the quality of the lip teeth has not been able to meet the ideal requirements, and there are technical difficulties in the measurement of the clamping force, and the inspection method is not scientific and reasonable. This difficult problem was shelved. In the revision of industry standards...
