Background technique
Gynaecology is a diagnosis and treatment subject of medical institutions, and it is with diagnosis and treatment women that gynaecology, which is branch's profession of gynemetrics,
Gynaecological disease is the professional department of diagnosis and treatment, is divided into doctor trained in Western medicine gynaecology and TCM Gynecology.Gynecological disease includes: the disease of female reproductive system
As gynecological disease, including vulva disease, vaginal disease, uterine disease, diseases of fallopian tubes, disease of ovary etc..
Curette is one of common surgical instrument of gynaecology, after operation, can generate some blood and waste in surgical wound surface
Tissue, needs to be removed in time with uterine curet, but existing curette, when entering and the positioning operation surface of a wound, curet neck angle
Degree is unable to adjust, and scraping key bit size not can control, and dilatation and curettage effect is undesirable, is not well positioned to meet operation needs.
Utility model content
Technical problem to be solved in the utility model is existing curette, when entering and the positioning operation surface of a wound, is scraped
Spoon neck angle is unable to adjust, and scraping key bit size not can control, and dilatation and curettage effect is undesirable, is not well positioned to meet operation needs.
To solve the above problems, the utility model provides a kind of gynaecology's curette, including expansion-head, conduit, plunger；It is swollen
Swollen head is membrane-like member made of the flexible elastic material of relaxation soft, and outer wall is equipped with several salient points, elastic material such as rubber
Or flexible plastic, the elongation percentage of material is minimum, wherein having the latex rubber compared with low surface tension, i.e., with relatively low pressure
The rubber of even inflation is most suitable material.The material of the film of expansion-head will meet easy expansion, expand full uterus with enough
Chamber, when the expansion-head that uterine cavity is partly or entirely expanded contradicts, salient point and the uterus cavity wall of expansion-head can be uniform
Ground contact forms certain extruding force, and the upper end of expansion-head is fixedly connected on the top of conduit, and inside is communicated with catheter interior,
Lower end is connected by fastener with conduit, and fastener can be nut, be threadedly coupled with conduit, is also possible to internal with washer
Ring, the lower end of expansion-head is fixedly connected with fastener, and such as plastic packaging, fastener is connected with conduit；
The coupling part of conduit and expansion-head is equipped with several openings, the chamber surrounded for connecting tube and expansion-head；It leads
Pipe is equipped with valve with expansion-head upper end junction, and valve includes valve plug, inlet opening and washer, and valve plug is bolt, major part part and pad
Circle interference fit, has therebetween certain pressure, and with the increase that inlet opening intakes, the power opened upwards increases, is greater than
After pressure between the two, valve is opened, and the liquid outflow inside expansion-head, expansion-head reduces, and microcephaly part is equipped with detent bolt, is blocked
Position bolt and pipe inner wall contradict, valve open when with washer card column, prevent valve plug from flying out, inlet opening be located at conduit top, valve plug
Microcephaly's beneath portions, the chamber surrounded with conduit and expansion-head communicates, and washer is made of flexible elastic material, such as rubber, position
In the top of conduit, expansion-head is fixedly connected on the outer wall at the top of this；
Plunger is the tubular structure of syringe, and one end is connected with conduit, and connectivity part is equipped with valve, and other end connection is lived
Plug, side wall are equipped with injection port, plug are equipped at injection port, by the upward fluid injection of piston.
Further, it is equipped with sealing ring between fastener and conduit, avoids leakage.
Further, the outer tube of plunger is transparent pipe, indicates scale above, convenient for controlling expansion-head by control reservoir quantity
Size and pressure.
Specific operation process is as follows:
Before use, closing the valve at plunger, even with liquid (such as water or physiological saline clean liquid) by injection port
It is logical, it twitches piston and then to block injection port with plug in the pipe of liquid injection plunger；Expansion-head is inserted at dilatation and curettage again,
The valve at plunger is opened, pushes piston to expand expansion-head, during which can shake gently curette, experience the expansion of expansion-head
Degree can also control degrees of expansion by control liquid inlet volume, (should when expansion-head and uterus cavity wall contradict and have certain pressure
Pressure is less than the pressure before valve plug and washer, can be controlled by liquid inlet volume), rotation or drag down curette carry out dilatation and curettage behaviour
Make, after dilatation and curettage, hauls out curette with strength, during which pressure increases, when greater than pressure before valve plug and washer, expansion-head
The indoor liquid outflow of chamber, plays the role of cleaning indirectly, then takes out curette.
The utility model has the advantages that:
1. the present apparatus fills expansion-head adjustment curette using liquid and scrapes a size, the uterus of Different Individual size is adapted to.
2. the full wall dilatation and curettage of uterine wall disposably may be implemented in the present apparatus, without adjusting the angle, the liquid discharged after dilatation and curettage can
It is more convenient to be rinsed.
Detailed description of the invention
Fig. 1 is the contraction state structural schematic diagram of the utility model；
Fig. 2 is the swelling state structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of this practical valve；
In figure, expansion-head 1, conduit 2, plunger 3, fastener 4, opening 5, chamber 6, valve 7, valve plug 71, inlet opening 72, washer
