Abstract
The invention belongs to a medical instrument and relates to a pair of portable tissue scissors with a micro visual structure, which is applied to minimally invasive surgical operations, comprises a tissue scissors main body, the micro visual structure and an external connector, and is characterized in that the direction conversion of the force is realized through the adoption of an articulation piece and an X-shaped ruff so as to meet the special requirement for operation in a tiny passage; the micro visual structure made of light-weight soft material internally comprises a water out-in flush passage, an optical fiber and a camera image transmission passage and can provide good view for operation, which brings convenience in operation; and connectors of the external connector and those of the micro visual structure are in one-one correspondence and in directional and positioning design, so that the mounting and dismantling are very convenient and simple. The pair of portable tissue scissors can be used for cutting off, separating and removing of downlink tissues in the tiny operation passage.
Description
Technical field
The present invention relates to a kind ofly cut for operating light tissue, a kind of little operating scissors of looking light specifically, little TV structure can be cut the visual field that provides good for tissue under small operation path.
Background technology
Traditional tissue is cut and can only be implemented in open surgery, but open surgical operation exists wound big, hemorrhage many, shortcomings such as corrective surgery fear, the long-term chronic pain of postoperative.In recent years, interior arthroscopic diagnosis has obtained fast development, and various endoscopies are applied to clinical.
But cutting edge and handle staggered form mechanics conduction mode that tradition tissue is cut, to open horizontal footpath degree bigger when the back Square handle, can't cut off operation expert the organizing of small operation path, and for addressing this problem, we have designed this light tissue with little TV structure and have cut.
Summary of the invention
The present invention cuts tissue with little TV structure and adopts integrated design, comprises Inlet and outlet water irrigation channel, light source optical fibers, photographic head and image pathway in little TV structure.Little TV structure not only has the function that the clear visual field is provided under mini-invasive incision, and has light advantage such as easy to operate.Organize shear structure also according to the specific (special) requirements of minim channel, no longer adopt traditional scissors bit and handle staggered form mechanics conduction mode.
The present invention includes: cutting edge, the axle collar, connecting rod, bar sheath, articulated elements, handle movable axis, handle mobility limit rod, last lower handle and little TV structure (including the external device interface at water flushing channel, water absorption channel, optical fibers and camera image transmission channel and rear) and external device.External device the place ahead is connected with little TV structure interface, and light source interface is arranged on the body, and image is defeated interface outward, bath and negative pressure suction interface.
Tissue is in the past cut and is compared, and the present invention possesses following characteristics.
1, cutting edge closed and open by its rear axis ring structure and change into moving up and down of connecting rod, avoided traditional tissue to cut because adopting cutting edge and handle staggered form mechanics conduction mode, the cutting edge that is caused by small operation path diameter restrictions when the back Square handle opens opens limited shortcoming.The horizontal activity of cutting edge becomes vertically moving of connecting rod, does not increase the horizontal footpath degree of trunk portion, makes its interior handled easily of minim channel again.
2, connecting rod is connected on the lower handle by articulated elements, and during the handle opening and closing, power moves up and down connecting rod by articulated elements, drives finally that cutting edge opens or closed.
3, go up lower handle and be provided with handle mobility limit rod, avoid causing because the handle movable amplitude is excessive this littlely to look light tissue and cut impaired.
4, little TV structure and tissue are cut the employing integrated design, be that little TV structure directly is fixed on tissue and cuts, comprising Inlet and outlet water irrigation channel, light source optical fibers, photographic head and image pathway in little TV structure can provide good surgical field of view for Minimally Invasive Surgery, simultaneously light, easy operating.
5, little TV structure rear is connected with external device, and interface adopts standard corresponding design one by one (as one protruding one recessed butt joint design), accomplishes seamless link, and is simultaneously for convenience detach, is convenient to change different apparatuses.
6, having bath interface, negative pressure suction interface, light source interface and image to fail interface outward on the external device is connected with outside rinse-system, television image system.
Description of drawings
Fig. 1: the present invention sees plane graph in whole side.
Fig. 2: body passageways of the present invention portion sectional view.
Fig. 3: the operation principle plane graph of cutting edge of the present invention and axle.
Among the figure: 1. water flushing channel, 2. water absorption channel, 3. optical fibers, 4. camera image transmission channel, 5. connecting rod passage, 6. bar sheath, 7. cutting edge, the 8. axle collar, 9. connecting rod, 10. external device interface, each one flushing in 11. both sides interface, 12. light source interface, 13. image is defeated interface outward, 14. articulated elements, 15. limit rods, 16. the handle movable axis, 17. little TV structures.
The specific embodiment
External device and tissue are cut the main body section disassembly, cleaning, behind the autoclaving.External device front end cuts with tissue that main part is nested to be connected, and the both sides intake-outlet connects water inlet pipe and water outlet pipe respectively on the external device, and light source interface and image output interface are connected with water rinse-system, television image system respectively.Open light source and television image system.Thumb and the third finger stretch into respectively up and down in the handle ring set, when thumb moves down, connecting rod by on push away, mechanical axis closes up and is " one " font, the cutting edge closure can arbitrarily enter or shift out the smile operation path this moment.When moving on the thumb, flexible handle and fixed handle separately push away under the connecting rod quilt, and cutting edge opens.After aim at determining need to cut off, separate or wiping out tissue, thumb promotes upper handle and moves down, and the cutting edge closure is finished shearing manipulation.
Claims (7)
1. the present invention relates to a kind of tissue for micro-wound surgical operation cuts, the direction that the articulated elements that this tissue is cut and the axle collar that intersects design realizable force transforms (1), little TV structure and tissue are cut integrated design (2), external device and little TV structure connector adopt corresponding, directed location, detachable design (3) one by one, and external device is connected (4) by interface with external system.
2. according to claim 1, the closure that it is characterized in that cutting edge becomes moving up and down of connecting rod with opening by its rear movable axis thaumatropy, this design becomes vertically moving of connecting rod to the horizontal activity of cutting edge, do not increase the horizontal footpath degree of trunk portion, make its interior handled easily of minim channel again.
3. according to claim 1, it is characterized in that connecting rod is connected on the handle by articulated elements, during the handle opening and closing, power moves up and down connecting rod by articulated elements, drives finally that cutting edge opens or closed.
