Description
Technical field
This utility model relate in a kind of Minimally Invasive Surgery, use percutaneous puncture deep thread catcher, be specially adapted to endoscope-assistant surgery, belong to technical field of medical instruments.
Background technology
Percutaneous puncture deep thread catcher is mainly used in Minimally Invasive Surgery field, especially endoscope-assistant surgery.Its effect is that percutaneous puncture enters body cavity, the end of suture is hooked and by suture from passage lira out, to facilitate the patient, take next step operation, such as fixing or traction sutures etc.
The domestic application that above thread catcher is not yet arranged, traditional method is first on skin, to open the little openning of 0.5 to 1 centimetre with scalpel, then by vascular forceps, by subcutaneous, poke until in body cavity, by suture clamp haul out again external.Do like this and be equivalent to open a duck eye again at body surface more, attractive in appearance not, and vascular forceps is more clumsy in the process of clamp, and not easy to operate.
The external existing patent that is applied to operating thread catcher, as the patent No. Deutsche Bundespatent that is DE 20 2,008 011 769, patent application is JIUYUE in 2008 4 days by the time.The shortcoming of this patent maximum is the blunt circle of its section, has only designed the function of hook line, and there is no the function of broken skin, and the design of its handle is equally also inconvenient when broken skin, puts forth one's strength.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that overcomes above-mentioned technology, and a kind of simple in structure, easy to operate Minimally Invasive Surgery percutaneous puncture deep thread catcher is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of micro-wound percutaneous puncture deep thread catcher, comprise the hands handle, push rod, shank and long sheath, it is characterized in that: handle central authorities are for for laying or linking push rod, the engraved structure of shank and long sheath, afterbody at handle is fixed with the collar, push rod is passed through by the central authorities of this collar, front end at push rod is provided with groove, and fix with the end of shank, push rod can drive shank and slide before and after its major axis, the front end outside of push rod is provided with a spring, this spring is at the engraved structure place of handle, the front end of shank is formed with and skin and subcutaneous each layer tissue can be worn out to the endoceliac tip of arrival, a groove that can hook sutures is arranged below tip at this, the end of long sheath is fixed in the engraved structure place of handle, and fit tightly with handle.
Preferably, described handle is Vespertilio shape structure, the impetus that the front end of the wing-shaped structure of Vespertilio shape structure both sides is forefinger and middle finger.
Preferably, the central portion that the end of described push rod is large thenar origin of force.
Preferably, when bringing pressure to bear on the central portion of described push rod end, described push rod drives described shank to front slide, and described spring compresses thereupon; When pressure removes, due to the restoring force of spring, by described push rod pushed home, thereby drive described shank homing.
Preferably, when bringing pressure to bear on the central portion of described push rod end, described push rod drives described shank to front slide, and expose from described long sheath at the groove of described shank front end and tip; When pressure removes, described push rod drives described shank homing, thereby the groove of described shank front end and tip are hidden in described long sheath again.
Preferably, the front end of described push rod is all the time in described engraved structure place.
Preferably, when described shank slides in described long sheath, described long sheath itself does not move.
Preferably, the length of described shank and described long sheath should guarantee that it can arrive organ surface by body surface; The rugosity of described shank and described long sheath should be carefully to postoperative without the seam skin, only need apply ointment or plaster to paste get final product thereon.
This utility model can be minimally invasive surgery a kind of novel thread catcher material fast and safely is provided, and does not need traditional broken skin instrument, and broken skin hook line accomplishs without any letup, and cut is little, postoperatively without the seam skin, simplifies procedures, and shortens operating time, guarantees the smooth success of operation.

The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
In conjunction with Fig. 1 a to Fig. 3 d, this utility model is comprised of handle 1, push rod 2, shank 3 and the large member of long sheath 4 four.Handle 1 is the Vespertilio shape, and Vespertilio both sides wing front end 5 is forefinger and middle finger origin of force.Handle central authorities hollow out 6, for laying or linking the large member of its excess-three.The handle afterbody is fixed wtih a collar 7, and these collar 7 central authorities have push rod 2 to pass through.The end central portion 8 of push rod is large thenar origin of force.Push rod front end 9 is central hollow out 6 places in handle all the time, and its front end 9 is designed with groove 10, with the end 11 of shank 3, fix, and can drive shank 3 and slide before and after its major axis.At handle central authorities hollow out 6 places, there is a spring 12 in push rod front end 9 outsides.Shank front end 13 is designed to complete the shape of two kinds of functions.The first can be worn out skin and subcutaneous each layer tissue and be arrived endoceliac most advanced and sophisticatedly 14, and it two is that a groove 15 that can hook sutures 17 is arranged below tip.Long sheath end 16 is fixed in central hollow out 6 places of handle, with handle 1, fits tightly.Shank 3 answers long enough enough thin with long sheath 4, and length can arrive organ surface by body surface; Rugosity should be carefully to postoperative without the seam skin, only need apply ointment or plaster to paste get final product thereon.
This Wicresoft's deep thread catcher without the pressure base state: spring does not compress 12, and push rod 2, in original position, does not drive shank 3 to front slide, and the main part of shank comprises the groove 15 of front end 13 and most advanced and sophisticated 14, all is arranged in the long sheath 4 of hollow.
The duty of this Wicresoft's deep thread catcher under pressure: a hands grips handle 1, forefinger and middle finger are placed in respectively the both sides wing front end 5 of Vespertilio shape handle, the large thenar of the same hand is placed in push rod end central portion 8 places, when bringing pressure to bear on push rod end central portion 8 with handle 1, push rod 2 drives shank 3 to front slide, spring 12 compresses thereupon, because long sheath end 16 is fixed in central hollow out 6 places of handle, can not move, the groove 15 of the shank front end 13 in long sheath 4 and most advanced and sophisticated 14 can expose fully from long sheath 4, now thread catcher can utilize on the one hand tip 14 broken skins exposed and subcutaneous tissue until in body cavity, can do on the other hand the front preparation of hook line, the groove 15 exposed is aimed to suture 17, in the situation that release pressure not, dilatory whole thread catcher hooks groove 15 smoothly by suture 17.
The recoil state of this Wicresoft's deep thread catcher when pressure removes: due to the restoring force of spring 12, by push rod 2 pushed home, thereby drive shank 3 homings, the groove 15 of shank front end 13 and most advanced and sophisticated 14 will be hidden in long sheath 4 again, if thread catcher has just arrived in body cavity, now most advanced and sophisticated 14 be hidden in long sheath 4 and can protect internal organs by most advanced and sophisticated 14 damages; If thread catcher has just hooked suture 17, now groove 15 openings are hidden in long sheath 4 and can guarantee that the suture 17 in groove 15 can not be left out in by hook, being pulled out external process.
