Problems solved by technology
During the use of the stapler, the firing force is one of the key technical indicators. Due to the internal structural design of the prior art stapler, the next effective firing can only be performed when the firing handle and the positioning handle are in contact with each other until they cannot move. Insufficient firing force will affect the normal use of the stapler. Since 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
In the prior art, the detection of the firing force of the stapler can only rely on the feel of the inspector, there is no effective method for detecting the firing force of the stapler, and there is no objective data support

The invention discloses an anastomat percussion force detection method. The anastomat percussion force detection method comprises the following steps: fixing an anastomat to be detected, and starting up a power supply; setting the maximum percussion force value X; selecting a detection mode, wherein the detection mode of the anastomat percussion force is an automatic mode or a manual mode; percussing the anastomat by using a transmission mechanism under the driving of a motor, and using a sensor for sensing the force generated by the motor, namely the percussion force; and outputting an obtained percussion force detection result to a display module after a data processing module acquires and processes the percussion force. The anastomat percussion force detection method has the beneficial effects that the percussion motion of a doctor during an operation is truly simulated for acquisition, processing and detection of data and digitization display of a percussion force detection force, thereby providing data support for the improvement of the performances of the anastomat percussion force.
Description
technical field [0001] The invention relates to a detection method for a surgical instrument, in particular to a detection method for the firing force of a stapler, which belongs to the field of medical instruments. 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 surgery has attracted more and more att...
