Description

Drawn with the closing for taking thing bag hard conduit opening under hysteroscope and combined the unit with control gas
Technical field
The present invention relates to a kind of medicine equipment, and in particular to a kind of to apply the assistor that Operated Specimens are taken out in hysteroscope art Tool.
Background technology
The specimen volume of the endoscope-assistant surgeries such as laparoscope excision is big, takes out difficult by stomach wall or the small otch of other body surfaces, presses According to without knurl principle, specimens from pri should load a kind of prevention of tumor and send out in the specimen bag of transfer, and after inflation specimen bag Crush and take out, this specimen bag has multiple hard conduits, and specimen bag is inserted into body cavity together with hard conduit first, then also needs Under hysteroscope monitoring, the end for clamping hard conduit proposes its end section to arrive external, but hard conduit end periphery is sharp Profit, lacks that safeguard procedures, easy injury tissue, and conduit are cylindrical to be difficult to clamp under hysteroscope in vivo, is opened in conduit Clamping tube wall is also difficult by the process of the outside drawing in abdomen wall puncture hole at mouthful, is especially taking completion tumor specimen crushing in thing bag Afterwards, hard conduit also needs to return to abdominal cavity, and catheter opening will likely cause tumour chip tissue to leak out in open state Come, cause to send out transfer in iatrogenic body cavity;Although temporary closure hard can be led by the way of filling in plug-like property management The mouth of pipe, it is likely that plug shaped article occurs when conduit is by body cavity and comes off, be retained in human body and cause a hidden trouble.
It is above-mentioned to also need to additional inflation and air valve function after hard conduit opening is pulled out in vitro in the prior art, But bore identical routine abdomen wall puncture device directly closed cannot be docked with hard conduit, is inserted directly into using puncture outfit casing tube Conduit inner potential necessarily increases the caliber of conduit, thus must just expand operative incision, increases the operation wound of patient.
The content of the invention
The present invention to be provided drawn with the closing for taking thing bag hard conduit opening under a kind of hysteroscope and combined the unit with control gas, be for The hard conduit opening of specimen bag provides one kind can as needed, can device and dismounting realize that a thing is more repeatedly in operation With, and possess various functions such as passivity closing, suitable traction, closed inflation.
The present invention is adopted the following technical scheme that to solve technical problem:
With the closing traction and being structurally characterized in that control gas is combined the unit for taking thing bag hard conduit opening under hysteroscope of the present invention: Including interior sheath universal joint, protection traction cap, epitheca air valve and split puncture cannula;The interior sheath universal joint is hard Tubular structure, using the interior sheath universal joint as take thing bag hard conduit connector assembly, the interior sheath universal joint Can be threadedly coupled with the protection traction cap using joint external screw joint, it is also possible to be connected with epitheca gas valve threads;It is described Split puncture cannula can be connected using sleeve external thread interface with the epitheca gas valve threads.
With the closing traction for taking thing bag hard conduit opening and the design feature of control gas modular appliance under hysteroscope of the present invention Lie also in:
The protection traction cap has the closing capped pipe of top closure, and crown is connected with the top of the closing capped pipe Ring, the hypomere pipe of the closing capped pipe is capped pipe internal thread interface, and the capped pipe internal thread interface is used for and interior sheath is general connects Joint external screw joint threaded connection in head, both can disassembly and assembly in vitro;The top of the closing capped pipe is in vault, The crown ring is easy for the ring bodies clamped under hysteroscope.
The top that the epitheca air valve has outer sheath, outer sheath is connected to the port of export of air valve, and the air valve is by filling Tracheae is connected with external gas source, and the hypomere pipe of the outer sheath is outer sheath internal thread interface, and the epitheca air valve is using outer Sheath internal thread interface is threadedly coupled with the joint external screw joint in interior sheath universal joint, and interior sheath is passed through using epitheca air valve Pipe universal joint is inflated to take thing bag;Endoscope-assistant surgery apparatus sequentially passes through air valve, outer sheath, interior sheath universal joint and takes thing Bag hard conduit and entering is taken in thing bag, and gas is sent out by interior sheath universal joint and outer sheath in preventing from taking thing bag using air valve Raw gas leakage.
The split puncture cannula is hard tubular structure, and split puncture cannula is outer with described using sleeve external thread interface Sheath gas valve threads connect the combining structure to be formed, using the combining structure as combined type stomach wall or wall of the chest puncture outfit.
The epitheca air valve is after completing to take the operation inflated in thing bag and crush specimens from pri, to be rotated institute in external State epitheca air valve to be removed from interior sheath universal joint, and installation protection traction cap is replaced on interior sheath universal joint, pass through Close interior sheath universal joint and then close and take thing bag.
Compared with the prior art, the present invention has the beneficial effect that:
1st, the present invention for take thing bag i.e. specimen bag hard conduit opening provide one kind can as needed, can perform the operation In repeatedly device and dismounting realize one-object-many-purposes, and possess can close, suitably traction, it is closed inflation etc. various functions.
2nd, the present invention is on the one hand vault in the end of hard conduit after taking thing bag and its hard conduit is placed into body cavity Shape closed, is the blunt closing of circle, it is possible to reduce damage and resistance, on the other hand also realize that the end of hard conduit can be led by clamp Draw;After hard conduit is drawn into vitro, hard conduit opening clear can be realized, and gas tube inflation can be connected Specimen bag, while gas leakage when preventing operating theater instruments from passing in and out of realizing that air valve is closed;After tumor specimen crushes taking-up in specimen bag, Can also closed hard conduit again distal opening, that is, realize closing conduit distal openings and be retracted into body cavity, so as to prevent to swell Transfer is sent out in the leakage of knurl chip.
3rd, the present invention carries out counterpart connection between each device, and dismantled and assembled, one-object-many-purposes help to economize on resources, and reduces Operation cost.
