All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the popularization of electrosurgical instruments, electric anastomats have been widely applied to open or minimally invasive general surgery, extrathoracic surgery, urology surgery and the like. At present, the electric anastomat comprises at least two cutting assemblies which are connected with the anastomat body in a switchable mode, and a doctor can replace the cutting assemblies according to operation needs. However, in the prior art, it is not determined whether the cutting assembly and the stapler body are normally mounted, and when the cutting assembly is not mounted or is not correctly mounted, if a firing action is performed, a malfunction or damage to an instrument is caused. Based on the problems of the related art, the present application provides a control scheme for a novel electric stapler according to the following embodiments, which can achieve the purpose of preventing the cutting assembly from being not mounted or not correctly mounted to perform the firing action, and improving the safety and reliability of the electric stapler.
For the purpose of understanding the control system of the present application, a description will be given below of an electric stapler to which the control system of the present application is applied. Referring to fig. 1, a schematic structural diagram of an electric stapler according to an embodiment of the present application is shown.
As shown in fig. 1, the electric stapler provided by the embodiment of the present application includes: the stapler body 01 and at least two switchable cutting assemblies 02 connected with the stapler body 01 are shown in fig. 2, which shows the cutting assemblies 02 with different cutting strokes, it can be understood that a user can select a cutting assembly 02 with a proper cutting stroke to be connected with the stapler body 01 when different cutting strokes are needed according to the type and the part of a cut tissue, in order to replace the cutting assembly 02, the cutting assembly 02 and the stapler body 01 are inserted, and in addition, the stapler body 01 is also provided with a firing switch for outputting a firing signal, a motor for driving the cutting assembly 02 to execute a cutting anastomosis operation, and the like.
The control process of the electric stapler provided by the present application is described in detail below.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a control system of an electric stapler provided in the present application, the control system including:
the component identification module 1 is used for generating an identification effective signal when the cutting component 02 is normally connected with the anastomat body 01;
specifically, the component recognition module 1 is configured to determine whether the cutting component 02 and the stapler body 01 are normally installed, and meanwhile, considering that the cutting component 02 having a plurality of different cutting strokes may be adapted to the stapler body 01, the component recognition module 1 is further configured to determine a cutting stroke of the cutting component 02 currently connected to the stapler body 01, and when the cutting component 02 is normally connected to the stapler body 01, generate a recognition effective signal corresponding to the cutting stroke of the current cutting component 02.
Specifically, in order to be able to automatically recognize the cutting stroke of the current cutting assembly 02 after the cutting assembly 02 is inserted into the stapler body 01, the assembly recognition module 1 provided in the present application may specifically include at least two sets of stroke recognition contacts 011 arranged in the stapler body 01, the stroke recognition contacts 011 correspond to the cutting stroke of the cutting assembly 02 one to one, that is, the stapler body 01 can be adapted to several cutting assemblies 02, then the stroke recognition contacts 011 of a corresponding number are arranged in the stapler body 01, and the stroke recognition contacts 011 are arranged at intervals along the installation direction of the cutting assembly 02. The stroke recognition contacts 011 are connected with the control module 3, so that after any stroke recognition contact 011 is switched on, the normal installation of the cutting assembly 02 and the anastomat body 01 is judged, and a recognition effective signal is sent to the control module 3, wherein the recognition effective signal comprises the cutting stroke of the cutting assembly 02 corresponding to the switched-on stroke recognition contact 011.
Meanwhile, an elastic contact piece 012 which is used for contacting with the stroke recognition contact 011 to select one of the stroke recognition contacts is also arranged in the anastomat body 01 so as to enable the stroke recognition contact 011 to be connected, and as shown in fig. 4, fig. 4 is a schematic diagram that the elastic contact piece 012 connects with one stroke recognition contact 011. It is understood that the stroke identification contact 011 preferably includes a fixed contact and a movable contact, and is in a normally open state, i.e. the movable contact is not in contact with the fixed contact in a normal state, and when the elastic contact piece 012 contacts the movable contact of the stroke identification contact 011, the movable contact is driven to be in contact with the fixed contact so as to send an identification effective signal to the control module 3.
Further, as shown in fig. 2, a stroke recognition part 021 for being connected with the stapler body 01 in a matching manner is provided on the cutting assembly 02, and the elastic contact piece 012 can be linked with the stroke recognition part 021, that is, when the stroke recognition part 021 is installed in the stapler body 01, the elastic contact piece 012 can be driven to move together while the stroke recognition part 021 moves. The stroke identifiers 021 correspond to cutting strokes of the cutting assemblies 02 one by one, and specifically, different stroke identifiers 021 have different assembly lengths, and if the cutting strokes of the cutting assemblies 02 are different, the assembly lengths of the stroke identifiers 021 are different. Therefore, when different stroke identifiers 021 are assembled into the stapler body 01, the moving distances of the different stroke identifiers 021 are different, so that the moving distances of the elastic contact pieces 012 linked with the different stroke identifiers 021 are different, and the positions of the stroke identifiers 011 can be arranged according to the assembly length of the stroke identifiers 021, so that after the stroke identifiers 021 are assembled in place, the elastic contact pieces 012 are contacted with the stroke identifiers 011 corresponding to the cutting assembly 02, and the stroke identifiers 011 are switched on.
Specifically, the stroke recognition contacts 011 are arranged side by side, and the distances from the elastic contact piece 012 to the stroke recognition contacts 011 are respectively equal to the assembly lengths of the stroke recognition parts 021 in a one-to-one correspondence manner. Therefore, when the stroke recognition part 021 is fitted in place, the elastic contact piece 012 can be surely moved in place, and the stroke recognition contact 011 corresponding to the stroke recognition part 021 is turned on, thereby outputting a recognition valid signal.
The position detection module 2 is used for generating an initial point effective signal when the cutting assembly 02 moves to an initial point;
specifically, the position detection module 2 is configured to detect a current position of the cutting assembly 02, and in order to reduce cost and volume, the position detection module 2 in this embodiment only detects whether the cutting assembly 02 reaches an initial point and a target point. The initial point is the initial position of the blade of the cutting assembly 02 when the cutting and anastomosis operation is performed according to the preset cutting stroke, and the final point is the final position of the blade of the cutting assembly 02 when the cutting and anastomosis operation is performed according to the preset cutting stroke. When the position detection module 2 detects that the cutting assembly 02 moves to the initial point, the cutting assembly 02 is judged to be capable of executing cutting anastomosis operation, an initial point effective signal is generated at the moment, and when the position detection module 2 detects that the cutting assembly 02 moves to the target point, the cutting operation is judged to be completed, and a target point effective signal is generated.
Specifically, the position detection module 2 may include a plurality of protrusions disposed on a rack inside the stapler body 01, and a plurality of stroke detection switches disposed on the stapler body 01, where the stroke detection switches may detect a stroke of the rack, and the protrusions may specifically refer to a top block, and the detection stroke switches may select one or more of a photoelectric type, an electromagnetic type, and a soft touch type. It will be appreciated that the rack is moved by the motor to move the cutting assembly 02 such that the cutting assembly 02 performs a cutting anastomosis operation upon actuation of the firing switch. Thus, the initial position of the rack corresponds to the initial position of the cutting head of the cutting assembly 02 and the end position of the rack corresponds to the end position of the cutting head of the cutting assembly 02.
Further, the plurality of stroke detecting switches may include an initial point detecting switch and a plurality of target point detecting switches. It will be appreciated that the cutting assemblies 02 of different cutting strokes correspond to the same initial point, and that different cutting assemblies 02 correspond to different destination points due to different cutting strokes, then the position of the destination point detection switch may be set according to the cutting strokes of the cutting assemblies 02. As the rack moves, the protrusions provided thereon may contact the stroke detection switch, thereby completing the detection of the stroke of the rack and the cutting assembly 02 and generating a corresponding position valid signal. For example, when the protrusion contacts the initial point detection switch, the initial point detection switch is enabled, it is determined that the rack is at the initial point, the blade of the cutting assembly 02 is at the initial position, an initial point effective signal is generated, along with the movement of the rack, the protrusion contacts a certain in-place point detection switch, the in-place point detection switch is enabled, it is determined that the rack reaches the reaching point, the blade of the cutting assembly 02 is at the end point position, a corresponding in-place point effective signal is generated, and the initial point effective signal or the in-place point detection signal is output to the control module 3, so that the control module 3 executes corresponding control operation according to the position of the cutting assembly 02.
Specifically, referring to fig. 5, taking three cutting assemblies 02 as an example, the position detection module 2 includes an initial point detection switch OPS, a first in-place point detection switch TS1, a second in-place point detection switch TS2, and a third in-place point detection switch TS3, a rack is provided with a first protrusion H1 and a second protrusion H2, the first protrusion H1 and the second protrusion H2 are separated by a predetermined distance, and correspondingly, the rack further includes a first groove, a second groove, and a third groove, wherein the width of the detection switch should not be greater than 5mm, the contact width is not greater than 2mm, the stroke is 1-3mm, preferably 2mm, the length of the first groove may be 20-40 mm, preferably 30mm, the lengths of the first protrusion H1 and the second protrusion H2 may be 5-15mm, preferably 11mm, and the length of the third groove may be 10-20mm, preferably 15 mm.
When the cutting assembly 02 and the stapler body 01 are normally installed, the first protrusion H1 on the rack contacts with the initial point detection switch OPS, at this time, the initial point detection switch OPS is effective to generate an initial point effective signal, and as the rack moves forward, the second protrusion H2 on the rack contacts with the in-position point detection switch TS, it can be understood that, considering that the cutting stroke of the cutting assembly 02 is different, the in-position point effective signal is not generated when any one of the in-position point detection switches TS is reached, and therefore, the in-position point effective signal is generated only when the cutting stroke of the second protrusion H2 and the current cutting assembly 02 corresponds to the in-position point detection switch contact. As a preferred embodiment, the stroke identification contacts 011 and the site detection switches TS are connected in series in a one-to-one correspondence manner, so that it is ensured that the site effective signal is generated only after the stroke identification contacts 011 corresponding to the current cutting stroke is turned on. Assuming that the component recognition module 1 includes the first stroke recognition contact DP1, the second stroke recognition contact DP2, and the third stroke recognition contact DP3 respectively corresponding to the cutting components 02 having lengths of 60, 45, and 30, assuming that the cutting component 02 currently connected to the stapler body 01 is the cutting component 02 having a length of 60, the first stroke recognition contact DP1 is valid, and when the second protrusion H2 contacts the second to-point detection switch TS2 or the third to-point detection switch TS3, the second to-point detection switch TS2 or the third to-point detection switch TS3 does not generate the effective signal until the second protrusion H2 contacts the first to-point detection switch TS1 along with the movement of the rack, and the first to-point detection switch TS1 generates the effective signal.
And the control module 3 is used for controlling the cutting assembly 02 to execute cutting anastomosis operation according to the first trigger signal output by the trigger switch after receiving the identification effective signal and the initial point effective signal.
Specifically, after the control module 3 receives an identification effective signal sent by the component identification module 1 and an initial point effective signal sent by the position detection module 2, it is determined that the blade of the current cutting component 02 has reached an assigned initial position, a cutting anastomosis operation can be executed, at this time, after a first trigger signal output by the trigger switch is received, the motor is controlled to rotate reversely, the rack is driven to move forward, so that the cutting component 02 is driven to move forward, and the cutting anastomosis operation is executed. In this embodiment, the control module 3 responds to the first trigger signal output by the trigger switch after receiving the identification valid signal and the initial point valid signal, so as to prevent the cutting assembly 02 from being mounted incorrectly or not being mounted correctly, and thus, the trigger action can be implemented, which causes malfunction or damage to the instrument.
With the forward movement of the rack, when the cutting assembly 02 reaches the arrival point corresponding to the cutting stroke, the arrival point detection switch outputs an arrival point effective signal, and when the control module 3 receives the arrival point effective signal, the cutting assembly 02 is controlled to execute the retracting operation. Specifically, after control module 3 receives the effective signal of the position point, control the motor through the electric current short circuit and independently brake, after receiving the second firing signal of firing switch output, control motor corotation, so that the rack moves backwards, thereby drive the blade of cutting component 02 and move backwards, when the rack moves backwards to the initial point, control module 3 receives the effective signal of the initial point of initial point detection switch OPS output promptly, control the motor brake through the electric current short circuit, and keep the motor in a braking state through the magnetic latching relay control motor, until installing next cutting component 02, thereby realize that new cutting component 02 of installation can only use again after cutting component 02 uses, realize the safe use of apparatus.
The application provides a control system of electronic anastomat, judge through subassembly identification module whether cutting assembly and anastomat body normally connect, judge through position detection module whether cutting assembly reaches the initial position of its cutting stroke, control module is after receiving the effective signal of subassembly identification module and position detection module output, just can respond the first signal of hitting of trigger switch output, in order to prevent to implement the trigger action under the condition that cutting assembly is not installed or is incorrectly installed, cause the condition of malfunction or apparatus damage to take place.
