Description

Visual RF---endometrial ablation cutter

Technical field

This utility model relates to a kind of operating theater instruments, relates in particular to a kind ofly can more effective realization endometrium excise the visual RF---endometrial ablation cutter for the treatment of gynaecopathia.

Background technology

Cutter (No. 99234356.9, the patent No.) is solidified in the endometrium excision of being invented by professor Qiu Xuehua in 1999, use so far, fully demonstrate good result safely and effectively, but it is in ablation procedure, and the effective speed that melts the cutter operation varies with each individual, and is wayward, simultaneously, the integrity of endocardial ablation can not be looked at straight, and the existing visual RF-endometrial ablation of development and design cutter can compensate its defect.

The utility model content

Solidify the effective speed of knife needle in order to overcome existing endometrium excision to the wayward cutter operation of different people, can not look at the deficiency of endocardial ablation integrity straight, this utility model provides a kind of improved endometrial ablation cutter---visual RF--endometrial ablation cutter, this cutter can be realized at different people than the effective speed that is easier to control the cutter operation, and can look at the integrity of endocardial ablation straight, satisfy the needs of clinical practice better.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of visual RF--endometrial ablation cutter, it is characterized in that: cutter hub links to each other with the knife bar that passes handle of a knife, the inner end near cutter hub of knife bar is placed with a fiber optics camera lens and aqueduct, optical fibers passes the knife bar central interior, by the through cutter hub arc structure inner edge of knife bar tail end, around fibre-optic is interstitial structure, and the connection power connection that connects radio-frequency therapeutic equipment is arranged in the handle of a knife.

The cutter hub of visual RF-endometrial ablation cutter is that the medical metal structure is made, is shaped as the loop-drive structure, the wide 10mm of arc, and the dark 12mm of arc, loop-drive is thick: preceding thick 4mm, both sides are 2mm; Knife bar is the medical metal structure, is shaped as tubulose, and the diameter internal diameter is 4mm, thickness of pipe wall 0.15mm; Knife bar central authorities are optical fibers, and diameter is 2mm, and by the through cutter hub arc structure inner edge of cutter tail, fibre-optic is interstitial structure on every side, and the image acquisition cable is arranged; Knife bar cover is medical poisonless, the heatproof material contracting with heat, thick 0.2mm, preceding to cutter hub, after connect handle of a knife, the knife bar cover is set in the knife bar surface; Handle of a knife is that the medical poisonless heatproof is injection molded, and the cross section is an oval structure, and major diameter is 30mm, minor diameter is 20mm, and long 40mm, handle of a knife are fixed on knife bar cover appearance, the knife bar prolongation is arranged in the handle of a knife, pass through optical fibers in it, and the metal structure that connects the power supply handle is arranged.The action principle of visual RF-endometrial ablation cutter is that cutter hub is got involved radio frequency electromagnetic to endometrium; Photoconduction is used for the thermal response effect behind the illumination observation single therapy cutter; Shooting will be treated the shooting of uterine cavity face and be conducted to display; The knife bar intermediate gap can be used for water filling cleaning shooting illumination head; Knife bar energy conduction electro-magnetic wave is to cutter hub; The cutter tail connects the treatment source on the one hand, can introduce illumination and shooting structure on the other hand.Visual RF--endometrial ablation cutter is applicable to constructed observation and the auxiliary diagnosis in the cavity of uterus, melts inner membrance, treats various neointimal hyperplasia, observes the speed that melts and the whole structure of inner membrance.

The operation principle of a whole set of instrument is by treating cutter, and------the treatment loop that loop pole plate---radio frequency source generator---treatment cutter forms, radio frequency source that can be controlled with power passes through the treatment cutter between arriving the human lesion position for human body and pathological tissues.Concrete using method is:

1, eliminates the inner membrance functional layer.

2, place visual RF-endometrial ablation cutter, open light source and observe in utero wall.

3, radiofrequency generator is put 50W power, starts power supply, in utero mouthful melting, observes to melt whether reach effect by the bottom, palace simultaneously, according to the observation, adjusts the speed that its cutter is divided a word with a hyphen at the end of a line.

4, melted after, observe whole inner membrane of uterine cavity and whether melt fully.

5, the anti-treatment of infection of postoperative.

The beneficial effects of the utility model are to understand the situation of uterine cavity before treatment; Observe according to the cavity of uterus depth, palace wall thickness and to the reaction difference of 50W power radio-frequency electrical energy and to regulate the speed of dividing a word with a hyphen at the end of a line that single melts cutter, avoid too fast or cross slow or unnecessary repetitive therapy; Can check whether inner membrane of uterine cavity melts complete; Can observe treatment back metrorrhagia point and healing state.
