Abstract
The utility model relates to undertissue forceps of an inner lens, which belong to the field of medical equipment, and mainly solve the problems that existing inner lens lower biopsy forceps clamp little amount of tissue blocks, are difficult to clamp when the biopsy forceps are not vertical to clamping tissues. The undertissue forceps comprise an operating grip, a force transmission guide wire, a spring cannula, a gasbag and a conduit and a binding clip component thereof, which are sequentially connected, wherein the inner cannula and the outer cannula of the operating grip are respectively connected with the force transmission guide wire and the spring cannula, the gasbag is connected on the tail end of the force transmission guide wire, a transverse slat is closely contacted with the lower portion of the gasbag, the gasbag conduit and the force transmission guide wire walk in a spring pipe, the gasbag conduit penetrates through the outer cannula wall and is exposed, a forceps channel with a sharp pointed end penetrates through a hole on the cross section of the tail end of the spring cannula through a force transmission rod and enters the spring cannula, and is connected on the force transmission guide wire by a flat head rivet. The undertissue forceps are mainly used for the biopsy of big blocks of tissue specimen, the spring cannula clamps tissues without being vertical to tissues, and tumor tissues blocking bronchus, oesophagus and intestinal tracts are cleaned out.
Description
Technical field this utility model relates to living tissue gripping pincers under a kind of novel scope, belongs to medical instruments field.
Biopsy forceps under the scope that the present medical field of technical background uses, mainly by operating grip,, power transmission seal wire, pogo barrel and binding clip assembly constitute; The flexible that its defective is scope has certain restriction to the size of binding clip assembly, biopsy forceps under the past scope is because the length of dowel steel is longer, limited the length in pincers roads greatly, make that the living tissue amount of gripping is little, when especially the tumor tissues of bronchus, esophagus, intestinal has been stopped up in treatment field gripping under scope, waste time and energy; Previously dehisce during the terminal level and smooth and biopsy in biopsy forceps pincers road its gripping of ambassador when organizing the degree of depth not enough, when biopsy forceps and the tissue of wanting gripping can not become 90 spend the right angle time gripping difficult.
The utility model content is for addressing the above problem, and this utility model provides a kind of gripping amount big and can organize parallel angle to organize living tissue gripping pincers under the scope of gripping with gripping.
This utility model by operating grip,, power transmission seal wire, pogo barrel, air bag and conduit thereof and binding clip assembly constitute:
Operating grip: operating grip is made up of inside and outside two sleeve pipes, and trocar sheath closely links to each other with pogo barrel, and inner sleeve links to each other with the power transmission seal wire.The trocar sheath side has the conduit of air bag to draw.
The power transmission seal wire: the traveling of power transmission seal wire is in pogo barrel, and the upper end links to each other with the operating grip inner sleeve, and the lower end links to each other with the dowel steel of binding clip assembly.The lower end of power transmission seal wire has air bag to adhere to, and has the transverse slat of being close to air bag to be connected in the power transmission seal wire, and transverse slat to the distance of the flat head rivet that seal wire links to each other with the dowel steel of binding clip assembly is made of the big tinsel of hardness.
Pogo barrel: the upper end links to each other with the trocar sheath of operating grip, and following end dissociative is rich in pliability.There are the duct of coming in and going out for the dowel steel of binding clip assembly, remainder shutoff in the two ends of terminal circular cross-section.
Air bag and conduit thereof: air bag is positioned at the lower end of power transmission seal wire, and in its conduit traveling and the pogo barrel, end passes the operating grip trocar sheath, and exposed parts has folder to close device, joint (connecing syringe) and stopper.
The binding clip assembly: binding clip assembly upper end links to each other following end dissociative with the power transmission seal wire; Form by dowel steel and pincers road (dowel steel and pincers road are an integral body).The dowel steel upper end is connected to the lower end of power transmission seal wire by flat head rivet; Two pincers roads are parallel to each other and coincide by the zigzag anastomotic stoma; There is fenestella at the edge in pincers road, and therebetween ultimate range equaled the diameter of pogo barrel when two pincers roads were closed; The pincers road is semiellipse type but most advanced and sophisticated sharp one-tenth needle point sample.

The specific embodiment
Be further described below in conjunction with accompanying drawing.The end that clamps (1) in an embodiment is sharp tip (14), makes pincers roads (1) can go deep into organization internal under the effect of external force; Two pincers roads (1) match by the articulation port (11) of indentation, and are convenient and strength-saving when gripping is organized; The arc dowel steel (15) of binding clip assembly enters pogo barrel (2) by the terminal duct (13) of pogo barrel (2) and is connected in power transmission seal wire (7) by flat head rivet (9), make pincers roads (1) length obvious prolongation is before arranged, make simultaneously power transmission seal wire (7) when moving up and down, clamp road (1) can the smoothness opening and closing; The end of power transmission seal wire (7) has a transverse slat (12), transverse slat (12) top has air bag (3) to be attached on the power transmission seal wire (7), extrusion spring sleeve pipe (2) and power transmission seal wire (7) when air bag (3) is inflated, make the external force that comes from pogo barrel (2) act on pincers road (1), obtain the external force of deep tissue by power transmission seal wire (7); Can make pincers roads (1) that dehiscing of different sizes arranged when air bag (3) is positioned at different positions in addition; There is balloon catheter (4) to be connected in air bag (3), balloon catheter (4) and power transmission seal wire (7) traveling are in pogo barrel (2), pogo barrel (2) upper end links to each other with trocar sheath (5), power transmission seal wire (7) upper end links to each other with inner sleeve (6), inner sleeve (6) part is positioned at trocar sheath (5) inside, make internal and external casing (6,5) when relatively moving power transmission seal wire (7) also relatively move with pogo barrel (2); Balloon catheter (4) passes trocar sheath (5) wall and exposes, and end has folder to close device (10), joint and stopper (8), makes the inflation venting of air bag (3) all simple.
