Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeSite preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based onEmbodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative workEmbodiment, broadly falls into the scope of protection of the invention.
It is an object of the invention to provide a kind of can enter safely abdomen, drain that is easy to use, being suitable for Multiple Type drainage tubePuncture pincers and drain pricking device, to solve the problems, such as above-mentioned prior art.
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings and specifically realThe present invention is further detailed explanation to apply mode.
Embodiment one
The present embodiment provides a kind of drain to puncture pincers, as shown in figure 1, including caliper 1 and binding clip 2, caliper 1 and binding clip 2 lead toCross a pincers axle 3 to connect, binding clip 2 is taper binding clip, is provided with drain pipe through-hole 4 in binding clip 2, and binding clip 2 includes symmetrically arranged theHalf binding clip 21 and the second half binding clips 22, the contact surface of the first half binding clips 21 and the second half binding clips 22 is plane, drain pipe through-hole 4Be symmetricly set in the first half binding clips 21 and the second half binding clips 22, drain pipe through-hole 4 along binding clip 2 length direction from binding clip 2One end passes through pincers axle 3 and extends to the other end of binding clip 2.
The drain of the present embodiment punctures pincers and may be manufactured without same model, adapts to different drainage tubes, under color ultrasound or ct guideUsed, puncture and in pincers binding clip 2, be provided with drain pipe through-hole 4, seal wire or drainage tube can be by being clamped the drain in axle and binding clipPipe through-hole enters abdominal cavity, and patient can be implemented under local anaesthesia that stomach wall sets up can indwelling peritoneal cavity drainage tube (including double-jacket tube etc.)Passage, drainage tube is inserted, and extracts drain puncture pincers, carry out drain, chamber drainage tube can be any after insertion drainage tubeModel, applied widely, reach the purpose of abundant drain seroperitoneums.
It is symmetrically arranged with finger-stall 11 outside caliper 1, facilitate medical personnel to use and operate.
As shown in Fig. 2 being provided with screw thread 23 on binding clip 2 lateral wall, screw thread 23 is distributed on the whole lateral wall of binding clip 2,Drain can be punctured pincers and slowly be screwed into intraperitoneal, also using binding clip 2, puncturing hole can be strutted as hindered during being screwed intoTo appropriate level, then carry out follow-up being screwed into, so can achieve that drain punctures slowly entering of pincers, the dynamics that enters is little, does not damageAbdominal cavity is organized.
The material of drain pincers is medical grade titanium alloy.
Embodiment two
The present embodiment provides a kind of drain pricking device, as shown in Fig. 1,3,4, including drawing in seal wire 5 and embodiment oneFlow through thorn pincers, the diameter of seal wire 5 is less than the diameter of drain pipe through-hole 4, and seal wire 5 front portion is provided with positioning convex 51, positioning convex51 external diameter is more than the external diameter of binding clip 2 front end.
Positioning convex 51 is spherical positioning convex.
Positioning convex 51 is apart from seal wire front end 8cm.
The part of seal wire 5 front end to positioning convex 51 is software material, Intraabdominal organ and tissue will not be caused hinderEvil, using safety.
Drain pricking device in the present embodiment is used under color ultrasound or ct guiding, during using drain pricking device,First use in puncture needle percutaneous access seroperitoneums or slough, insert the seal wire 5 with positioning convex 51 for the front end, positioning convex 51Positioned at abdominal cavity it would be desirable to the drainage tube using is placed in the drain pipe through-hole 4 that drain punctures in pincers, then drain puncturesPincers insert or are screwed into along seal wire 5 abdominal cavity, and binding clip 2 is provided with screw thread 23 on lateral wall, drain can be punctured pincers and slowly be screwed into abdomenIntracavity, also can be strutted puncturing hole to appropriate level using binding clip 2 as hindered during being screwed into, then carries out follow-up twistingEnter, so can achieve that drain punctures slowly entering of pincers, the dynamics that enters is little, do not damage abdominal cavity tissue；Positioning convex 51 canClamped with stopping that drain punctures, prevent drain from puncturing pincers and enter the too deep injury tissue of abdominal cavity, drainage tube is punctured by drain and clampsInterior drain pipe through-hole 4 enters abdominal cavity, finally drain is punctured pincers and slowly extracts and can keep away it is achieved that drainage tube enters abdomen safelyExempt from Accessory injury.
Apply specific case in the present invention principle of the present invention and embodiment are set forth, above exampleIllustrate that being only intended to help understands the method for the present invention and its core concept；Simultaneously for one of ordinary skill in the art, according toAccording to the thought of the present invention, all will change in specific embodiments and applications.In sum, this specification contentShould not be construed as limitation of the present invention.
