The waveform image of display and the waveform of default tissue compare, so that it may judge whether clamped tissue is preset group easily
It knits.
To sum up, the surgical clamp 010 that the embodiments of the present invention provide is pressed by being arranged on the second plier piece 120
Force snesor 300 detects the pressure that clamped tissue itself peristaltic wave generates, and passes through display device 400 for pressure change waveform
It shows, allows a user to easily pass through and compare the waveform of waveform and default tissue that display device 400 is shown, from
And judge whether clamped tissue is default tissue, it reduces and accidentally injures.And the surgical clamp that the embodiments of the present invention provide
010 by being arranged preamplifier between pressure sensor 300 and display device 400, the waveform for showing display device 400
It is more accurate, improve judgment accuracy.And it is easy to operate, easy to use.
Embodiment 2
A kind of method for judging clamped organization type is additionally provided in the embodiments of the present invention, this method is based on real
The realization of surgical clamp 010 of the offer of example 1 is provided.Below by taking the surgical clamp 010 that embodiment 1 is recorded as an example, this method is carried out
Explanation.Method includes the following steps:
SO1: clamped tissue is clamped using surgical clamp 010.
Clamping part 100 is placed in adjacent tissue to be held, finger is placed in finger ring 230, and driving operation portion 220 is to close to solid
Determine the movement of portion 210, then the first plier piece 110 moves closer to the second plier piece 120, clamps clamped tissue.
SO2: pressure sensor 300 detects the pressure change that clamped tissue itself peristaltic wave generates.
Since the second plier piece 120 is arranged in close to the first plier piece 110 in the survey pressure probe 310 of pressure sensor 300
One end is surveyed pressure probe 310 and is contacted with clamped tissue, due to being clamped the effect of tissue itself peristaltic wave, pressure sensor 300
The pressure detected will appear fluctuation.
SO3: display device 400 shows the waveform for the pressure change that pressure sensor 300 detects.
The pressure signal that pressure sensor 300 will test is converted to electric signal output, and display device 400 receives telecommunications
It is converted into corresponding waveform image after number, and shows.
SO4: waveform and predetermined waveform are compared；If waveform is consistent with predetermined waveform, it is default for being clamped tissue
Tissue.
After user observes the waveform image that display device 400 is shown, by the peristaltic wave of the waveform and default tissue
The predetermined waveform that the pressure change of generation generates compares.If the waveform is consistent with predetermined waveform, illustrate clamped group
It is woven to default tissue, can be performed the operation；If the waveform is inconsistent with predetermined waveform, illustrate that clamped tissue is not default
Tissue, not can be carried out operation, avoids accidental injury.
Since the method provided in this embodiment for judging clamped organization type is the surgical clamp provided based on embodiment 1
010 realizes, therefore also has and can judge whether clamped tissue is default tissue easily, reduces and accidentally injures, and easy to operate,
Beneficial effect easy to use.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
