Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of visual abdominal cavity exocoel dilator, include sleeve pipe 101, bat-handle switch 104, sleeve pipe handle
105, two lead to 106, perforator cutter pipe 301, perforator handle 302.The specification of sleeve pipe 101 can be 3mm, 5mm,
Tetra-kinds of regular sizes of 10mm and 12mm, conveniently carry out different operation technique.Described sleeve pipe 101 is outside be provided with
The casing bit 100 of anti-slip umbrella, sleeve pipe handle 105 adds single hole transducer 200, arranges in perforator cutter pipe 301
There is telescopic anti-penetrator.Described perforator cutter pipe 301 is internal to be provided with draw-in groove 307 and offers locating slot 305 on draw-in groove 307,
The bottom of telescopic anti-penetrator 303 is stuck in draw-in groove 307 by spring shaft 304, and spring shaft 304 lower end is provided with positioning sliding block
306, positioning sliding block 306 is stuck in locating slot 305.
As it is shown in figure 5, telescopic anti-penetrator 303 is not when meeting obstructions, slightly protrude from outside perforator cutter pipe 301, protrude
Position in point of a knife.When the perforator 300 with telescopic anti-penetrator punctures enter abdominal cavity through skin incision, telescopic anti-
Penetrator 303 is extruded the spring shaft 304 of bottom by tissue and is compressed by this resistance so that telescopic anti-penetrator
In 303 retraction perforator cutter pipes 301, cutter pipe will not be hindered to puncture.When abdominal cavity broken through by perforator, telescopic anti-wear
303 are no longer influenced by pressure, and telescopic anti-penetrator 303 is sprung back to slightly protrude from outside perforator cutter pipe 301 by spring shaft 304
Position, user can stop continue puncture.By rationally presetting locating slot 305 and the position of positioning sliding block 306, can
To help telescopic anti-penetrator 303 good location.
When manufacturing, the retractility of telescopic anti-penetrator 303 needs sensitive, can accurately experience breakthrough sense during puncture,
And resistance during puncture can not be increased.Can accurately judge whether perforator breaks through abdomen by the retractility of telescopic anti-penetrator
Chamber, if breaking through abdominal cavity, should stop continuing to puncture, can effectively prevent from injuring internal organs.
Described casing bit 100 main body with anti-slip umbrella is to be arranged on another layer outside sleeve pipe 101 to have resilient bullet
Property sleeve pipe 110, its underpart is provided with anti-slip umbrella 102, and its top is provided with external screw thread 103, bat-handle switch 104 is internal be provided with
The bat-handle switch screw thread 109 that external screw thread 103 engages in gear type.
The described casing bit 100 with anti-slip umbrella is fixing with sleeve pipe 101 below anti-slip umbrella 102 to be connected, and it connects
Mode can be to use ultrasonic bonding, it is also possible to for by arranging match recessed on spring-backed quill 110 and sleeve pipe 101
Male buckle 108 thus connect fixing by groove.
As in figure 2 it is shown, described anti-slip umbrella 102 is formation after the circle strip hollow slots offered on spring-backed quill 110
Paliform structure, because casing bit 100 main body of anti-slip umbrella is to be arranged on another layer outside sleeve pipe 101 to have elasticity
Spring-backed quill 110, so paliform structure is running into pressure as it is shown on figure 3, because of the hands within bat-handle switch 104
Handle switch screw thread 109 engages in gear type with external screw thread 103, therefore the external screw thread 103 on anti-slip umbrella 102 top is opened at handle
After the upwards Guan Bi of pass 104, spring-backed quill 110 produces folded deformation after producing downward displacement, and paliform structure is formed and opens
Open the anti-slip umbrella 102 of the umbrella of state, such that it is able to lock collar position, prevent cannula slide, for the accurate behaviour of operation
Make to provide stable support.Strut diameter more than skin incision size, it is ensured that sleeve pipe will not up skid off.
With above-mentioned principle, the external screw thread 103 on anti-slip umbrella 102 top is after bat-handle switch 104 closes downwards, and paliform is tied
The anti-slip umbrella 102 of structure can set back formation closure state, and the anti-slip umbrella 102 under closure state is fitted with sleeve pipe 101,
Do not increase resistance during sleeve pipe turnover.
When manufacturing, the anti-slip umbrella 102 of paliform structure needs folding freely, need to close when entering abdominal cavity under closure state
Closing tight must not increase resistance；Need easily open anti-slip umbrella after entering abdominal cavity with the casing bit 100 of anti-slip umbrella
102, and can stably support, sleeve pipe landing will not be made；Need to close when taking out sleeve pipe and tight must not scratch tissue.
It is additionally provided with skin surface retainer ring 107, when laparoscopic cannula enters on the described casing bit 100 with anti-slip umbrella
Behind abdominal cavity, anti-slip umbrella 102 can be launched in sleeve pipe front end, make the sleeve pipe cannot be up, coordinate the skin table of sleeve pipe rear end simultaneously
Face retainer ring 107, makes the sleeve pipe cannot be descending, thus plays comprehensive fixed effect.
As shown in Figure 4, described single hole transducer 200 includes transducer upper cover 201 and transducer lower cover 202, transducer
Being provided with elastomer 203 between upper cover 201 and transducer lower cover 202, it is elastic that elastomer 203 lower end is provided with the many lobes of shutter
Body 204, elastomer 203 central authorities offer the elastomer passage 205 being connected with shutter many lobes elastomer 204.Described
The fixing seat 206 matched with elastomer 203 it is additionally provided with, fixing seat 206 between transducer upper cover 201 and transducer lower cover 202
Setting be further ensured that air-tightness.
The predeterminable diameter less than operation apparatus of elastomer passage 205 of elastomer 203 central authorities, thus formed the most airtight
Protection set, prevents gas from leaking, it is ensured that stablizing of air pressure, simple to operate, and perfect in shape and function is nontoxic, aseptic, more traditional
Puncture instrument there is incomparable superiority.
Shutter many lobes elastomer 204 is fixed on elastomer 203 lower end, structure likeness in form camera shutter according to certain angle spiral.
When different-diameter apparatus enters, all can live by tight, thus further ensure air-tightness.
Single hole transducer 200 is suitable for the operating theater instruments turnover of different-diameter, it is not necessary to repeatedly extracts sleeve pipe, saves operating time,
Improve procedure efficiency.
Although describing and illustrate this utility model here by certain or some particular arrangement, but it being not intended to limit
Make described details, because various amendment and structure change may be had in the range of patent requirements, without departing from spirit.
This utility model relates to part and the most same as the prior art prior art maybe can be used to be realized.
