Abstract
The invention discloses an operating instrument for hydraulically expanding a cervical canal. The operating instrument is simple and convenient to operate, capable of reducing discomfort of subject and suitable for artificial abortion. The front end, namely a dilatation body, of the operating instrument is inserted into the cervical canal, a pressure injection handle is pressed through a finger, and conduction of hydraulic pressure is utilized to enable the dilatation body to dilate to rated diameter and to enable the cervical canal to dilate to meet operating requirements; after a depressurizing buckle is pressed down, the dilatation body contracts to be in an initial state, the operating instrument is taken out to complete the dilatation process. The operating instrument has the advantages of simple operation and short operation process.
Description
Technical field:
The present invention relates to the technical field of medical surgical instrument, particularly relate to one and utilize hydraulic principle to expand flexible material, reach the mechanical connecting structure of operation object.
Background technology:
Termination of pregnancy operation is done at the department of obstetrics and gynecology of hospital, normally insert successively from minor diameter to major diameter with the metal cylinder of different-diameter and take out the cervical canal of human body, cervical canal is expanded gradually, finally makes germ cell depart from body of uterus, reach the object of miscarriage.Therefore, operation process is long, complex operation, and operating theater instruments uses many, causes having a big risk of nosocomial infection.For now, a kind of solution of operating theater instruments of artificial abortion simple and easy to operate is still lacked.
Summary of the invention:
The object of the present invention is to provide a kind of easy and simple to handle, reduce the surgical instrument of the artificial abortion of operation receiveing person's discomfort, it is by the front end of this utensil and expansion body intron cervical canal, by finger presses note pressure handle, utilizes the conduction of hydraulic pressure, expansion body is made to expand into specified diameter, make cervical canal be expanded to the requirement of operation, after pressing pressure release button, expansion body is contracted to original state, take out utensil, complete process of expansion.There is easy and simple to handle, that operation process is short feature.
To achieve these goals, technical method of the present invention is: a kind of surgical instrument of hydraulic dilatation cervical canal, and it mainly comprises: light weight and processing technology plastic structures, internal layer rubber finger sleeve, outer rubber finger sleeve, sizing fibre sleeving, check valve, piston, liquid storage cylinder, retractable sack, relief valve etc. well.It is characterized in that: have retractable sack in liquid storage cylinder, there is the "O"-ring of liquid-leakage preventing cavity port junction, and expansion body is multilayer flexible material structure, and there are two check valves plunger shaft front end, and pressure release button controls reflux inlet and moves.
Accompanying drawing explanation
Fig. 1 section of structure of the present invention
Fig. 2 partial enlarged drawing of the present invention
Detailed description of the invention:
Below in conjunction with accompanying drawing and example, the invention will be further described, and the present invention mainly comprises: structure 1, note pressure handle 3, piston 4, check valve 10, check valve 7, reflux inlet 8, pressure release buckle 9 and expansion body 2.It is characterized in that: there is multiple chamber its inside of structure 1 in accompanying drawing 1, they are: liquid storage cylinder 6, check valve 10 chamber, reflux inlet 8 chamber, piston 4 chamber, check valve 7 and retractable sack 5 is provided with in liquid storage cylinder 6, there is an elongated orifice in the middle of the narrow end of structure 1, communicate with the core pipe 15 in check valve 10 and expansion body 2 respectively; Retractable sack 5 in accompanying drawing 1 is air bags with good telescopic resilience, in order to regulate the pressure of liquid storage cylinder 6 liquid return.
The formation of expansion body 2 of the present invention is such: the core pipe 15 in accompanying drawing 2 is elongated bodys, its one end is connected with the narrow end endoporus of structure 1, core pipe 15 skin is internal layer rubber finger sleeve 14, the skin of internal layer rubber finger sleeve 14 is sizing fibre sleevings 13, the skin of sizing fibre sleeving 13 is outer rubber finger sleeves 12, and the opening of outer rubber finger sleeve 12 has dead ring 16.
Using function of the present invention is achieved in that
In FIG when the finger presses note pressure handle 3 holding expansion utensil, promotion piston 4 is pushed the liquid of intracavity open check valve 10 and is entered elongated orifice, inject internal layer rubber finger sleeve 14 by the aperture 11 of core pipe 15 front end and make its volumetric expansion, and act on outer field sizing fibre sleeving 13 and outer rubber finger sleeve 12 together expands, after finger unclamps note pressure handle 3, piston 4 is replied, vacuum is produced in piston chamber, check valve 7 is opened, by the liquid sucker chamber in liquid storage cylinder, move in circles like this, constantly by the liquid input expansion body 2 in liquid storage cylinder, after sizing fibre sleeving 13 expand into nominal diameter, expansion body 2 would not continue to expand, now its pressure of pressing is continued to note pressure handle 3 and can feel obvious increase, stop pressing, the meanwhile minimizing of liquid storage intracavity liquid can make the volumetric expansion of retractable sack 5, when pressing pressure release button 9, to promote reflux inlet 8 descending, make liquid return in expansion body 2 in liquid storage cylinder, the contraction of retractable sack 5 volume at this moment then can accelerate the process of liquid return, and the state before making expansion body 2 be contracted to use.
