Abstract
The utility model relates to a kind of vaginal dilators for operation on cervix, the vaginal dilator includes at least enlarged portion (200) and at least one probe (102), it is characterized in that, the enlarged portion (200) includes the first expanding plate (201), second expanding plate (202) and limit handle (203), second expanding plate (202) is connect in a manner of integral type with the limit handle (203) being bent interconnecting piece (204), first expanding plate (201) and the second expanding plate (202) are provided with arc-shaped curved surface and are pivotally fixed in the opposite mode of arc-shaped curved surface by bolt, wherein, the curved surface of second expanding plate (202) is provided at least one diversion trench (301), at least one deflector hole (300) and diversion cavity (3 02), the vaginal dilator of the utility model can either effectively export the blood in surgical procedure, but can rotating detector to check the different location of uterine neck, keep operation on cervix convenient and efficient.
Description
Technical field
The utility model relates to medical equipment technical field more particularly to a kind of vaginal dilators for operation on cervix.
Background technique
Vaginal dilator is also known as vaginal dilator, is mainly used for gynaecology's routine inspection, operation, what present vaginal dilator used
Duck-beak type above and below being, and duckbilled amplitude protrusion is higher, and it is larger to fill in vagina pain sense, because duckbilled amplitude is higher, checks medicine-feeding
When will increase the amplitude of strutting, increase feeling of pain.
In recent years, in order to which the intrauterine surgical for solving gynemetrics's Via vagina in the course of surgery can accurately and effectively in real time
It monitors whole process, to increase the safety and success rate of operation, reduces the pain of patient, shorten operating time, many professions
Personage, individual or entity come up with many different schemes, mainly include two major classes: the first kind is exactly the original using optical imagery
Reason and design by clinically be known as endoscopic or micro-tubular, weakness be exactly after camera lens occupies blood stains or steam image just obscure
It is unclear, as bleeding pollution camera lens causes image just to fall flat.Second class is exactly the principle with ultrasonic imaging, benefit
Sub- art process is monitored in real time with the super probe Via vagina of B, and " ultrasonic guidance formula " is also referred to as by clinic.The ultrasound of this kind of equipment is visited
Head is not required to enter uterine cavity, is only isolated with disposable gum cover when reusing, and is not required to complicated disinfection treatment, and such at present
Equipment shows as the improvement to vaginal speculum, or the improvement to ultrasonic probe shape, or is improved simultaneously the two and combined
Form a complete set of use.Two o'clock clinically is concentrated mainly on to the evaluation of this kind of equipment, first is that degree easy to use, since gynaecology passes through
The intrauterine surgical anesthesia duration of vagina is short, does not allow complex operations and delays operating time；Second is that adapting to the individual difference of patient
Property.It varies with each individual, the position in uterus can be divided into anteposition, rear position and interposition etc., and oneself is used for clinical production currently on the market
Product design scheme cuts both ways.
Chinese patent CN201558124U discloses a kind of rotary vagina ultrasonic probe, including probe mechanism and vagina are peeped
Device is equipped with concave edge in the nextpage of vaginal speculum or upper page, and the neck tube matching of probe mechanism is embedded in the concave edge, and is peeped in vagina
Device nextpage or upper page are provided with sonde body mounting hole, and neck tube end is provided with damping knob.Although the patent is visited by rotation
Head solves the technical issues of checking various positions uterus in the course of surgery, but the patent can not still solve accumulation of blood
The technical issues of influencing operation.
The highest anticoagulant of clinical use frequency includes: non-bowel medication anticoagulant (such as heparin, hirudin), tonka-bean
Plain anticoagulant class (such as warfarin), anti-platelet aggregation medicinal (such as aspirin).Heparin, hirudin are natural
Anti-coagulants.
Bio-medical material (Biomedical Materials) be for being diagnosed, treated to organism, repaired or
Replace its disease damage tissue, organ or the material for promoting its function.Bio-medical material includes biological medical polymer material.This reality
In novel, the vaginal dilator for operation leads to the materials such as unmodified polystyrene, polypropylene and is made.Polystyrene, polypropylene
Equal materials belong to biological medical polymer material.
