Abstract

The utility model relates to a puncture outfit, in particular to a disposable puncture outfit. The utility model comprises a puncturation needle and a puncturation cannula sheath assembly. The device is characterized in that: the puncturation pin is inserted in the puncturation cannula sheath, the puncturation inner core of the puncture outfit aims right at puncturation position, the puncturation bit hides in the puncturation inner core. The utility model has the advantages that: delicate, reasonably designed in structure and convenient in use, the device avoids the trouble of repeat sterilization of puncture outfit and the possibility of pathogen infection and provides absolute protection without damage to intracavitary tissue.

Description

One-time-use Perforator

Technical field

This utility model relates to a kind of perforator, especially relate to a kind of can disposable perforator.

Background technology

Along with the continuous development raising of Medical Technology, laparoscopic surgery is approved fully by numerous medical workers and patient that the characteristics of laparoscopic surgery mainly are to cut open the belly, and wound is little, and post-operative recovery is fast, and the patient suffering is few, therefore, is accepted by extensive patients.Laparoscopic surgery mainly is to rely on medical endoscope, and operative region is passed through the camera system amplification imaging to television screen, implements operation through watching television image.Need perforator on human body, to form an instrument channel when doing laparoscopic surgery, the perforator of hospital's use at present divides two kinds, a kind of is reusable perforator, this perforator causes the cross infection of pathogenic bacteria easily, and to perform the operation forward and backward to the perforator trouble of cleaning, sterilize very at every turn.Though another kind is an One-time-use Perforator,, there is certain risk because puncture does not have protector or protector not to shield, thereby damages intraluminal tissue in use easily.

Summary of the invention

At above-mentioned deficiency, this utility model provides a kind of disposable perforator, has both avoided reusing the sterilization trouble and the courses of infection of perforator, can play absolute protective effect again, can not damage intraluminal tissue.

The technical scheme in the invention for solving the above technical problem is: this One-time-use Perforator comprises puncture needle, puncture cover sheath parts, it is characterized in that puncture needle is inserted in the puncture cover sheath, then the puncture inner core of perforator is aimed at the site of puncture, the puncture cutter head is ensconced in the puncture inner core.Press safety button during use, drive the safety lock button and move down the insurance block, the certain strength of reuse is pushed ahead perforator, at this moment just setback backward of the puncture inner core of puncture needle head, expose the puncture cutter head, the puncture cutter head of this moment will pierce through skin, after waiting to pierce through skin, the puncture inner core will eject, the cutter head that will puncture is ensconced in-core in the puncture, in order to avoid the damage intraluminal tissue, the cover sheath that will puncture again utilizes spiral lamination toward puncture deep precession to clockwise direction, extract puncture needle at last, puncture cover sheath just can be used as instrument channel and carries out laparoscopic surgery.This One-time-use Perforator integral body is small and exquisite, easy to use, and has avoided the trouble of perforator repeated disinfection and the possibility of courses of infection.

Described puncture needle be provided with insurance block, insurance activity buckle, insure reset buckle, safety lock is buckled, safety button, button block, puncture back-moving spring, snap close back-moving spring, puncture cutter head, the inner core and the shell that punctures puncture.

Described puncture cover sheath is provided with O type circle, cross sealing shroud, sealing shroud, cover sheath shell, breather valve, spiral lamination.

Adopt technique scheme, the beneficial effect that brings to this utility model is: simple in structure, safe and reliable, overall volume is small and exquisite, and use is flexible, convenient, at 100,000 grades of clean room ethylene oxide sterilizings, can carry out disposable puncture uses, make things convenient for hospital's cleaning, sterilizing program, avoid accidental injury, for medical industry provides a novel puncture device.

The specific embodiment

Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with key diagram.

Embodiment: referring to Figure of description 1-accompanying drawing 3, in this utility model, be provided with safety button (7) and push-button reset device in puncture needle (1) shank, the push-button reset device comprises insurance block (3), insurance activity button (4), insures reset button (5), safety lock button (6), button block (8), snap close back-moving spring (10), be provided with puncture back-moving spring (9) in puncture needle (1) shank, head is provided with puncture cutter head (11), the outer puncture inner core (12) that is surrounded by of puncture cutter head (11), the outer puncture shell (13) that is surrounded by of puncture inner core (12).

Puncture cover sheath (2) shank is provided with sealing shroud (16), and cross sealing shroud (15) is arranged in the shank, and cross sealing shroud (15) upper end is an O type circle (14), and cover sheath shank is provided with breather valve (18) outward, and cover sheath shell (17) bar portion is provided with spiral lamination (19).

During use puncture needle (1) is inserted in the puncture cover sheath (2), then the puncture inner core (12) of perforator is aimed at the site of puncture, press safety button (7), drive safety lock button (6) and move down insurance block (3), the certain strength of reuse is pushed ahead perforator, at this moment just setback backward of the puncture inner core (12) of puncture needle (1) head, expose puncture cutter head (11), the puncture cutter head (11) of this moment will pierce through skin, after waiting to pierce through skin, puncture inner core (12) will eject, the cutter head (11) that will puncture is ensconced in the puncture inner core (12), in order to avoid the damage intraluminal tissue, the cover sheath (2) that will puncture again utilizes spiral lamination (19) toward puncture deep precession to clockwise direction, extract puncture needle (1) at last, puncture cover sheath (2) just can be used as instrument channel and carries out laparoscopic surgery.

This utility model perforator has been avoided the trouble of perforator repeated disinfection and the possibility of courses of infection, and is whole small and exquisite, easy to use, has wide use promotion prospect.

Should be pointed out that at last above embodiment only is the more representational example of this utility model.Obviously, this utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
