Abstract
An expendable excised tissue taking-out device for the surgical microwound operation features that a notch is made on internal sheath's handle for breaking off the handle to separat the self-destroyed internal sheath, and the external sheath and its handle and the puncture device can be with drawn out along the internal sheath. It is made of the medical high-molecular material except the expanding and recovering wire which is made of shape memory NiTi alloy.
Description
Technical field
The present invention relates to a kind of micro-wound surgical operation apparatus, particularly under endoscope, be used for reclaiming the minimally invasive surgery resection organization extractor of the biological tissue of excision.
Background technology
The present invention is based on the improvement to inventor's patent of invention ZL03146815.2 and utility model patent ZL03274545.1.
The inventor has announced a kind of bag mouth that can open specimen bag after specimen bag enters the abdominal cavity automatically in patent ZL03146815.2 and ZL03274545.1, is convenient to receive thing; Simultaneously can seal bag mouth again behind the thing receiving, play the biological sample reclaiming bag of lasso trick effect, in clinical, obtain using widely.In use simultaneously, also there are some problems, are enclosed within inconvenience taking-up between epitheca pipe and the handle as perforator (Trocar), and reusable phenomenon is arranged clinically.Cross infection that brings for fear of repeated use and the taking-up that makes things convenient for perforator need provide a kind of new technical scheme, can reduce cost significantly, can make things convenient for perforator to take out again, make things convenient for operation technique, particularly can self-destruction, prevent to reuse, avoid cross infection.
Novelty of the present invention is:
One-off device for extracting tissue cut away in minor traumatic surgery, comprise that reclaiming bag 1, shape memory metal open and exhausting line 2, epitheca 5, epitheca handle 5-1, interior sheath 4, interior sheath handle 4-1, it is characterized in that on interior sheath 4 near interior sheath handle 4-1 place have one broken in the recessed of sheath be pickled with grains or in wine 6.
---be pickled with grains or in wine near sheath in interior sheath handle 4-1 place broken recessed on the sheath 4 in above-mentioned and 6 be generally the V font.
The present invention since on the interior sheath 4 of one-off device for extracting tissue cut away in minor traumatic surgery near interior sheath handle 4-1 place have one broken in the recessed of sheath be pickled with grains or in wine 6.During clinical use, behind the reclaiming bag 1 of specimen being included in tissue extractor for endoscope operation, sheath 4 in can fractureing along recessed poor 6 places on the interior sheath 4, interior sheath handle 4-1 is separated with interior sheath 4, epitheca 5 and epitheca handle 5-1 can withdraw from along interior sheath 4, and perforator 7 also can withdraw from along interior sheath 4 simultaneously, makes things convenient for operation technique.The present invention's parts open except shape memory metal and exhausting line 2 adopts the manufacturing of niti-shaped memorial alloy silk, remaining can adopt the medical macromolecular materials manufacturing, greatly reduces cost, self-destruction after simultaneously interior sheath 4 fractures, can avoid reusing, effectively prevent cross infection.
Description of drawings
Fig. 1 is the structural representation of the present invention's disposable minimally invasive surgery resection organization extractor.
Fig. 2 is the structural representation after amplify in Figure 1A district.
Fig. 3 is the structural representation after the present invention's the fractureing of disposable minimally invasive surgery resection organization extractor.
Fig. 4 is the structural representation after amplify in Fig. 3 B district.
Among the above-mentioned figure:
1 is reclaiming bag, and 2 for shape memory metal opens and exhausting line, 3 biological tissues for excision, and 4 is interior sheath, and 4-1 is the handle of interior sheath, and 5 is epitheca, and 5-1 is the epitheca handle, and 6 is the recessed poor of broken interior sheath, and 7 is perforator (Trocar).
Specific embodiment
Adopt the medical macromolecular materials thin film after heat seal, to make reclaiming bag 1.Adopting recovery temperature is 20 ℃～25 ℃, and the niti-shaped memorial alloy silk of diameter between 0.3mm～0.8mm makes it more than recovery temperature behind the typing heat treatment, has identical diameter to open as shape memory metal and exhausting line 2 with the bag mouth of reclaiming bag 1.Shape memory metal opened and after exhausting line 2 passes along the interlayer hole on the bag mouth of reclaiming bag 1, shape memory metal opens and the tinsel head of exhausting line 2 adopts chemical adhesive to be fixed on the far-end of interior sheath 4, with reclaiming bag 1 folding being placed within the front end of epitheca 5, being about to reclaiming bag 1 and being installed within the epitheca 5.It is recessed poor 6 to open V-type with specific purpose tool on interior sheath handle, recessed poor 6 the degree of depth of V-type the wall thickness of interior sheath 4 1/3～1/2 between, install epitheca handle 5-1 and interior sheath handle 4-1, promptly obtain the present invention's disposable minimally invasive surgery resection organization extractor.
During clinical use, with the present invention's disposable minimally invasive surgery resection organization extractor by perforator 7, stretch into the abdominal cavity, return and remove epitheca 5, the reclaiming bag 1 that is folded in epitheca 5 front ends is discharged fully, under the effect of body temperature, the toroidal the when shape memory metal of niti-shaped memorial alloy silk manufacturing opens and exhausting line 2 recoveries are finalized the design, the bag mouth that drives reclaiming bag 1 opens, and is convenient to be contained in the biological tissue 3 of excision.After the biological tissue 3 of excision includes reclaiming bag 1 in, sheath 4 in can fractureing along recessed poor 6 places of interior sheath, interior sheath handle 4-1 is separated with interior sheath 4, epitheca 5 and epitheca handle 5-1 can withdraw from along interior sheath 4, perforator 7 can withdraw from along interior sheath 4 simultaneously, return at last and remove interior sheath 4, the bag mouth of reclaiming bag 1 is moved to outside the little otch in abdominal cavity, launch the bag mouth of reclaiming bag 1, stretch into surgical instruments in reclaiming bag 1, broken and taking-up resection organization is after the broken taking-up of most resection organizations, further return and remove interior sheath 4, can fully take out external by little otch residual fragment of tissue or tissue fluid in the reclaiming bag 1.
Claims (2)
1, one-off device for extracting tissue cut away in minor traumatic surgery, comprise that reclaiming bag 1, shape memory metal open and exhausting line 2, epitheca 5, epitheca handle 5-1, interior sheath 4, interior sheath handle 4-1, it is characterized in that on interior sheath 4 near interior sheath handle 4-1 place have one broken in the recessed of sheath be pickled with grains or in wine 6.
2,, be pickled with grains or in wine near sheath in interior sheath handle 4-1 place broken recessed on the sheath 4 in it is characterized in that and 6 be generally the V font according to the described one-off device for extracting tissue cut away in minor traumatic surgery of claim 1.
