Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
Embodiment 1, as shown in Figure 1, Figure 2 and Figure 3: a kind of puncture outfit includes epitheca 1, is provided with inner cavity 12 in epitheca 1,
During surgery, puncture needle first can be put into the inner cavity 12, puncture procedure then is carried out to patient, after puncture, by puncture needle
It takes out, is put into endoscope.In surgical procedure, the stress of vertical direction is had, is easy so that epitheca 1 and patient body slip,
In order to preferably fix, outside the side wall of epitheca 1, if upper anti-slip part 11.The anti-slip part 11 may include multiple tread plates
Line, so that epitheca 1 is preferably fixed with patient body.
After puncture, in order to maintain the air pressure balance of patient affected part, operating space is provided for operation, is needed to patient
Operative region input air-flow.Epitheca 1 is equipped with air intake vent 3, but in the prior art, what is be blown into is all cold wind, on the one hand meeting
The temperature of endoscope is reduced, on the other hand, cold gas is to being also irritating at the injury of patient.
In the present embodiment, heating device is equipped in the inner cavity 12 of puncture outfit, heating device includes wind-heat device 5 and solid heat
Device 6 also includes driving device and heat source.Driving device can be dry cell, be also possible to external power supply, and heat source can be electricity
Heated filament gives off heat after being powered.
5 one end of wind-heat device is connect with air intake vent 3, and the other end is just connect with inner cavity 12, in the present embodiment, wind-heat device
5 include optimization air duct 51, and optimization air duct 51 is close to heat source, it acts as air-flow heating time is extended, enables air-flow and heat source
It comes into full contact with, increases heating effect.Specifically, optimization air duct 51 can be spiral shape, or straight line, curved shape.In this way
Setting so that into the wind inside patient body be hot wind, on the one hand, reduce the sense of discomfort of patient, on the other hand, can go
Except the fog on endoscope, furthermore it is also possible to be lifted stomach wall with wind-force, space is provided for operation.
On the basis of this, also comprising solid thermal 6, in the present embodiment, Gu thermal may be provided in interior equally close to heat source
In chamber 12, it can be single or multiple that physical structure, which can be contact 61,.In the present embodiment, it is presented as multiple contacts
Monolithic.Monolithic is contacted by the heat effect of heat source, temperature increases, and solid contact occurs with endoscope, transfers heat to interior peep
Mirror.The reason of being arranged in this way is, although wind-heat device 5 can provide heating effect, removes fog, heat-supplying mode is gas after all
Heat radiation is flowed, heating effect is limited, in addition, will receive operation air pressure balance, considering not increase sense of discomfort to patient, wind-force is not yet
What is be preferably arranged is too big, it is certain need to be brought rapidly up endoscope when, be just unable to satisfy this demand for heat.And solid thermal
6 be the material contact of solid and solid, and the heat transmitting between solid occurs, heat is directly passed to endoscope, so that endoscope
It is brought rapidly up.
In the present embodiment, it is also additionally arranged switching device 7, the effect of switching device 7 is to switch solid thermal 6 and endoscope
Whether contact.Specifically, switching device 7 is a plate-inserting structure, user press...withes one's finger dynamic inserted sheet, and inserted sheet will solid 6 He of thermal
Endoscope contact, user stirs inserted sheet with finger outward, then admittedly thermal 6 far from endoscope.Such structure user
It chooses whether to be rapidly heated using solid thermal 6.
For more precise control temperature, it is additionally provided with temperature sensor and display device, temperature sensor is in detecting
The Current Temperatures of sight glass, display device then show the temperature value of sensor.
After air-flow enters human body, in order to avoid air-flow is flowed backward, sealing gland knot can be equipped on inner cavity 12 and upper cover 2
Structure 4, air seal structure 4 include multiple valves 41, and multiple valves 41 are around setting, by direction close to each other gradually to the epitheca 1
Bottom angled, multiple 41 centers of valve be collectively formed gas supply stream pass through by mouth 42.If air-flow backflows, inner cavity
12 bottom is flowed backward, then valve 41 can be jacked up by air-flow, can be reduced or be closed by 42 nature of mouth, to inhibit to backflow.
Embodiment 2: from embodiment 1 to be distinguished as the installation site of solid thermal 6 of heating device different.As shown in figure 4,
In embodiment 1, Gu thermal 6 and wind-heat device 5 are integrated in inner cavity 12, in the present embodiment, Gu thermal 6 is seperated,
It is individually external except puncture outfit, it can be an independent heating structure.In actual use, user can first by endoscope and
Gu thermal 6 contacts, realization is brought rapidly up, and endoscope is put into inner cavity 12 again after heating and carries out operation, in the course of surgery
Heat maintenance rely on wind-heat device 5.
Embodiment 3, different from the structure for being distinguished as switching device 7 of embodiment 1, in the present embodiment, switching device 7 is
Matched screw thread is provided on one retaining mechanism, switching device 7 and epitheca 1, switching device and solid thermal 6 are equipped with mutual
The inclined-plane matched, user twist switching device 7, and switching device 7 starts to rotate, and change the position on 1 vertical direction of epitheca, oblique
Under the conflict in face, Gu displacement in the horizontal direction occurs for thermal 6, to change at a distance from endoscope.
