Moreover, whether the driving mechanism of the puncture outfit works or not is controlled only through the power switch, and medical personnel who need to operate the puncture outfit not only need to observe the condition of the puncture assembly in the patient body in real time, but also need to observe the working condition of the driving mechanism at the same time, so that the operation of the medical personnel is inconvenient, and the probability of accidental injury of the puncture assembly to the tissues in the patient body is easily increased.
The application provides a puncture outfit and a puncture method, which aim to solve the technical problems in the prior art.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
The embodiment of the application provides a puncture outfit, which is shown in fig. 1 in a schematic structural view, is shown in fig. 2 in a schematic view of a partial internal structure of the puncture outfit shown in fig. 1, and is shown in fig. 3 in a schematic frame view of the puncture outfit shown in fig. 1. This puncture ware includes: a first switch 10, a driving mechanism 20, a first button 30, a camera 40, an electric signal detection unit 50, a second switch 60, a control device 70 and a power supply 80.
The first switch 10, the driving mechanism 20, the first button 30, the camera 40 and the electric signal detection unit 50 are all in communication connection with the control device 70; the electric signal detection unit 50 and the control device 70 are electrically connected with the driving mechanism 40 and are used for detecting the working state of the driving mechanism 40; the second switch 60 has one end electrically connected to the control device 70 and the other end electrically connected to the power source 80.
In the puncture instrument provided in the embodiment of the present application, the first switch 10, the driving mechanism 20, the first button 30, the camera 40, and the electric signal detection unit 50 are all communicatively connected to the control device 70, so that the control device 70 can control the driving mechanism 20 to stop driving according to a stop driving signal based on the first switch 10, the first button 30, the camera 40, and/or the electric signal detection unit 50. If the controller 70 fails to control the driving mechanism 20 to stop driving based on the stop driving signal, the second switch 60 is triggered to cut off the electrical connection between the driving mechanism 20 and the power source 80, thereby achieving an emergency stop of the driving mechanism 20.
In the puncture outfit provided by the embodiment of the application, the driving stopping mechanism of the driving mechanism 20 is controlled by various safety protection measures, so that the situation that the driving mechanism 20 cannot be normally stopped can be prevented from occurring after the single safety protection measure fails, the safety protection performance of the puncture outfit can be improved, and the probability that the puncture assembly of the puncture outfit causes accidental injury to tissues in a patient body can be reduced.
In the embodiment of the present application, the first switch 10, the driving mechanism 20, the first button 30, the camera 40 and the electric signal detecting unit 50 of the puncture outfit are all connected to the control device 70 in communication. The first switch 10 and the first button 30 are used to generate a corresponding stop driving signal if triggered, so that the control device 70 controls the stop driving of the driving mechanism 20 according to the stop driving signal. Optionally, the drive mechanism 20 includes a drive motor.
Optionally, the camera 40 is configured to monitor puncture image information during a puncture process during operation of the puncture device, and when it is recognized that the puncture image information contains a set identifier, send a driving stopping signal to the control device 70, and the control device 70 controls the driving stopping of the driving mechanism 20 according to the driving stopping signal. The electrical signal detecting unit 50 is further electrically connected to the driving mechanism 40, and is configured to monitor an operating state of the driving mechanism 20 during the operation of the puncture device, and send a driving stopping signal to the control device 70 when the operating state of the driving mechanism 20 is not satisfied with a set condition, and the control device 70 controls the driving stopping of the driving mechanism 20 according to the driving stopping signal. The specific working principle of the puncture device provided in the embodiment of the present application in the puncture process will be described in detail later with reference to the puncture method, and will not be described again here.
In the embodiment of the present application, one end of the second switch 60 is electrically connected to the control device 70, and the other end is electrically connected to the power source 80, so that in the case that the driving mechanism 20 cannot be controlled to stop driving through the first switch 10, the first button 30, the camera 40 or the safety protection measure of the electric signal detection unit 50, the second switch 60 is triggered to cut off the electrical connection between the power source 80 and the control device 70, that is, the electrical connection between the driving mechanism 20 and the power source 80, thereby achieving an emergency stop of the driving mechanism 20.
Alternatively, the second switch 60 is operated in the normal on state, i.e. in the conducting state between the power source 80 and the control device 70. When an emergency occurs, the second switch 60 can effectively cut off the electrical connection between the power source 80 and the control device 70 through the physical operation of the user, and when the electrical connection between the power source 80 and the control device 70 needs to be restored, the electrical connection between the power source 80 and the control device 70 can be restored through the physical operation of the second switch 60 consciously by the user. Alternatively, the power supply 80 includes a dry cell battery, a storage battery, or the like.
As will be understood by those skilled in the art, since one end of the second switch 60 is electrically connected to the control device 70 and the other end is electrically connected to the power source 80, when the user is faced with an abnormal situation during the operation of the puncture instrument, the user can also directly cut off the electrical connection between the power source 80 and the control device 70 through the second switch 60, so that the driving mechanism 20 stops driving for the first time. An abnormal situation faced by the user may be a situation in which, during the puncturing process of the puncture instrument, the user observes, with the aid of an endoscope, that the puncturing assembly of the puncture instrument may be about to cause accidental injuries to the tissues inside the patient's body.
In the embodiment of the present application, the second switch 60 is a mechanical switch, so that the second switch can directly cut off the circuit connection between the power supply 80 and the control device 70, thereby improving the reliability of the emergency stop of the driving mechanism 20 by the second switch 60.
Alternatively, the initial operation state of the second switch 60 is a normally closed state, i.e., the power supply 80 and the control device 70 are in an off state. The second switch 60 is a mechanical switch, and when the user uses the switch, the power source 80 and the control device 70 are turned on in advance to operate the puncture device, and when the user uses the switch, the second switch 60 is turned off.
In the puncture outfit provided by the embodiment of the application, any one of the safety protection measures of the first switch 10, the first button 30, the camera 40 or the electric signal detection unit 50 is triggered universally, so that the driving mechanism 20 can stop driving, and the puncture outfit can be conveniently used by medical staff. Furthermore, after any of the above safety measures fails, the second switch 60 may be used to cut off the electrical connection between the driving mechanism 20 and the power source 80, so as to control the driving mechanism 20 to stop in an emergency. The stop driving of the driving mechanism 20 is controlled by multiple safety protection measures, so that the situation that the driving mechanism 20 cannot be normally stopped after a single safety protection measure fails can be prevented, the safety protection performance of the puncture outfit can be improved, and the probability that the puncture assembly of the puncture outfit causes accidental injury to tissues in a patient body can be reduced.

When the user operates the first switch 10 to reset, the control device 70 controls the conduction of the circuit between the power source 80 and the driving mechanism 20 and between the power source and the camera 40. The triggering mode of the first switch 10 includes touching, pressing, clicking and the like.

Alternatively, the Processor may be a CPU (Central Processing Unit), a general-purpose Processor, a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array) or other Programmable logic device, a transistor logic device, a hardware component, or any combination thereof.

In one embodiment of the present application, controlling the driving mechanism 20 to stop driving based on the third stop driving signal of the camera 40 includes: when the control device 70 satisfies the setting requirement based on the puncture image information transmitted from the camera 40 while the drive mechanism 20 of the puncture instrument is in operation, a third stop drive signal is generated so that the drive mechanism 20 stops driving based on the third stop drive signal.
A flowchart of the control device 70 for generating the third stop driving signal based on the camera 40 is shown in fig. 4, and includes the following steps S401 to S405:
s401, puncture image information sent by the camera is received.
Alternatively, the control device 70 receives the puncture image information transmitted by the camera 40.
S402, determining whether the color value of the puncture image information meets a first setting requirement; if yes, the process proceeds to S403, and if not, the process returns to S401.
Alternatively, the control device 70 may puncture whether the color value of the image information meets the first setting requirement, for example, the color value includes an R/G/B value. The first setting requirement is: the R value is more than 200, the R value is more than the G value, and the R value is more than the B value.
And S403, extracting texture information from the puncture image information.
During the puncturing process, the texture of superficial tissues such as skin and the texture of internal tissues of the human body are different, and thus, the puncturing position of the puncturing member 90 can be determined based on the texture information.
S404, determining whether the distance between adjacent textures in the texture information is larger than a set distance threshold value; if yes, the process proceeds to S405, and if not, the process returns to S403.
Optionally, the distance threshold is set to 4 mm.
S405, a third stop driving signal is generated.
In one embodiment of the present application, the control device 70 may generate the third stop driving signal based on the camera 40, and during the puncturing process, there is a difference between the brightness of the punctured image information obtained by the camera 40 when the skin surface is punctured and after the skin surface is punctured, and therefore, it is determined whether to generate the third stop driving signal according to the brightness information of the punctured image information sent by the camera. Specifically, the control device 70 is configured to analyze the information of the puncture image at a set reading frequency, and optionally, the control device 70 analyzes one puncture image every 66 milliseconds, and reads the brightness value of each pixel point in each puncture image, and the brightness value is represented by a numerical value of 0 to 255.
The average brightness value of the whole puncture image is obtained by accumulating the brightness values of all the pixel points, and a change curve of the average brightness value of the puncture image is formed, as shown in fig. 5, the abscissa represents time in units of s (seconds), and the ordinate represents the average brightness value. The change that the puncture image is gradually reduced by a certain amplitude is identified through a hill climbing algorithm, and when the puncture image enters a brightness change area for the first time, namely the area indicated by A in the figure 5, the puncture image is identified as starting to enter the puncture process; when the blood pressure in the blood pressure region enters the brightness change region, i.e. the region B in fig. 5, it is indicated that the puncture assembly 90 penetrates the superficial tissues at this moment, and a third stop driving signal is generated to control the driving mechanism 20 to stop rotating, so that the intelligent control puncture is realized, the safe puncture effect is achieved, and the internal tissues are effectively prevented from being accidentally injured.
In one embodiment of the present application, controlling the driving mechanism 20 to stop driving based on the fourth stop driving signal of the electric signal detection unit 50 includes: when the control device 70 determines that the current signal sent by the current detection unit is greater than the first threshold value in the operating state of the drive mechanism 20 of the puncture instrument, a fourth drive stop signal is generated so that the drive mechanism 20 stops driving in accordance with the fourth drive stop signal.
In the embodiment of the present application, when the control device 70 determines that the current signal sent by the current detection unit is greater than the rated current, the control device 70 generates a fourth stop driving command, and controls the driving mechanism 20 to stop driving according to the fourth stop driving signal. Therefore, the phenomenon that the driving mechanism 20 is in an overload state for a long time and is damaged to cause a halt can be avoided, and the puncture assembly 90 is prevented from accidentally injuring the tissues in the body of a patient.
By applying the embodiment of the application, at least the following beneficial effects can be realized:
in the puncture instrument provided in the embodiment of the present application, the first switch 10, the driving mechanism 20, the first button 30, the camera 40, and the electric signal detection unit 50 are all communicatively connected to the control device 70, so that the control device 70 can control the driving mechanism 20 to stop driving according to a stop driving signal based on the first switch 10, the first button 30, the camera 40, and/or the electric signal detection unit 50. When the control device 70 fails to control the driving mechanism 20 to stop driving based on the stop driving signal, the second switch 60 is triggered to cut off the electrical connection between the driving mechanism 20 and the power source 80, that is, the electrical connection between the power source 80 and the other parts of the puncture instrument, thereby achieving an emergency stop of the driving mechanism 20.
In the puncture outfit that this application embodiment provided, through the stop drive of multiple safety protection measure control actuating mechanism 20, can prevent that single safety protection measure from becoming invalid the back, lead to the condition that actuating mechanism 20 can not normally stop to appear to can improve the safety protection performance of puncture outfit, can reduce the probability that the puncture subassembly of puncture outfit caused the accidental injury to the internal tissue of patient.
