A moving component used in a stapler firing force detection device and its detection device

Abstract

The invention discloses a moving component for a detection device, which includes a first connecting rod, a second connecting rod and a third connecting rod, the moving component is used to convert linear motion into arc motion; the first connecting rod One end of the rod is connected to the first pivot point, the middle portion of the first link is connected to the first end of the second link; the second end of the second link is connected to the third link The first end of the rod is connected; the second end of the third link is connected with the second pivot point; the power is transmitted from the second pivot point to the third link, and then to the second link rod, and then transmitted to the first connecting rod, so that the first connecting rod is in contact with or separated from the detected object. According to the moving component used for the detection device and the detection device with the same of the present invention, the power loss is small in the force transmission process, the detection force value can be effectively transmitted, the percussion force is detected and the detection value is digitally displayed, and the stapler The performance improvement of firing force provides data support.

Description

technical field [0001] The invention relates to a detection device of a surgical instrument, in particular to a moving component used in a stapler firing force detection device and a detection device thereof, belonging to the field of medical devices. Background technique [0002] The stapler and its executive components suitable for surgical operations are surgical instruments that can remove excess tissue while suturing the patient's wound. It is widely used in minimally invasive surgery such as abdominal surgery, gynecology, pediatrics, and thoracic surgery. Excision and anastomosis. The operation carried out under the endoscope generally only needs to open several small holes on the patient's body, and excision, suturing tissue and auxiliary instruments are inserted into the patient's body through the small holes for surgery. Minimally invasive surgery brings little trauma to patients, and patients can recover in a short period of time. Therefore, minimally invasive sur...

AI Technical Summary

Problems solved by technology

Due to the internal structural design of the existing stapler, the next effective firing can only be performed when the firing handle and the positioning handle cannot be moved each time. Insufficient firing force will make the firing handle not fully contact with the positioning handle and affect the anastomosis normal use of the device

In this case, it can only be fired again, and because the patient's tissue is clamped in the end effector of the stapler, firing again will cause accidental injuries such as tearing to the patient, affecting the normal operation

Therefore, it is necessary to detect the firing force of the stapler, and the detection of the firing force of the stapler in the prior art can only rely on the feel of the inspector, there is no effective device for detecting the firing force of the stapler, and there is no objective data support

However, there is no moving component suitable for the stapler detection device in the prior art, and the function of the stapler detection device cannot be realized.
