Ein neues Konzept für makroskopische Anastomosen des Vas deferens — Nahtmaterial und Operationstechnik —
Für bilaterale Skrotalexploration bei der Infertilität wird der "infrapubische" Zugang empfohlen. Polyglactinsäure hat sich als Nahtmaterial sehr gut bewährt. Bei Epididymovasostomie sind resorbierbare Schienen nicht nützlich, bei Vaso-Vasostomie dagegen hilfreich. Der Rillenspatel macht die Handhabung der Instrumente einfacher und schützt das Vas deferens.  相似文献

Summary A newly developed brain spatula with transparent tip for brain retraction is introduced. The high-molecular polymer plastic material is used only for the tip of the new spatula whilst rest of the spatula is made up of the ordinary malleable metal. The transparent nature of the spatula tip helps us in observing the retracted brain vessels and cranial nerves in continuity with the main operating area. The extent of distortion as a result of the retraction can be directly observed assisting in prevention of an inadvertent injury. The new brain spatula with transparent tip is helpful for microneurosurgery under high magnification. Various shapes and sizes of the spatula can be used.  相似文献

Summary

In laparoscopic surgery, the key to the effective use of electrocautery is to aim an appropriately-shaped tip to the target tissue at a precise angle. However, each laparoscopic electrocautery currently available has its own fixed tip shape, so the surgeon must change the whole insulated steel rod to accommodate different electro-dissecting situations. Recognizing that there is a significant number of points for improvement, we developed a laparoscopic instrument called ojigi electrocautery that has a freely mobile triangular-shaped tip. This instrument was found to be useful in many kinds of electro-dissection, especially when separating the gall bladder from the liver bed. The freely rotatable ojigi electrocautery is currently being developed to provide greater freedom and control.  相似文献

A new and successful technique for goniosynechialysis is described. The essentials of the technique include: (1) use of the chamber deepening procedure to provide a wide, safe entrance to the angle; (2) use of sodium hyaluronate to hold the deepened configuration and to stop and localize bleeding, thus maintaining visibility; (3) use of an irrigating cyclodialysis spatula to hold the deepened chamber, to stop bleeding and to perform the lysis; and (4) direct visualization of the angle. Four cases with severe synechial angle closure of one year's duration or less were cured. An additional case of longer duration was significantly improved. The procedure should be considered for those patients who have developed significant synechial angle closure and high pressure, and in whom the synechiae have not been present for a prolonged period of time.  相似文献

Background

In women with cancer-related hysterectomy, the vaginal vault cytology has a low efficacy - when performed by conventional methods – for the early detection of vaginal recurrence. The amount of exfoliated cells collected is generally low because of atrophy, and the vaginal vault corners can be so narrow that the commonly used Ayres spatula cannot often penetrate deeply into them. This prospective study aimed at identifying the advantages obtained in specimens collection using the cytobrush, as compared to the Ayres’s spatula.

Patients and methods.

141 gynaecologic cancer patients were studied to compare samplings collected with Ayre’s spatula or with cytobrush. In a pilot setting of 15 patients, vaginal cytology samples obtained by both Ayre’s spatula and cytobrush were placed at the opposite sites of a single slide for quali-quantitative evaluation. Thereafter, the remaining 126 consecutive women were assigned to either group A (spatula) or B (cytobrush) according to the order of entry. The same gynaecologist performed all the procedures.

Results

In all 15 pilot cases, the cytobrush seemed to collect a higher quantity of material. The comparative analysis of the two complete groups indicated that the cytobrush technique was more effective than the spatula one. The odds ratio (OR) for an optimal cytology using the cytobrush was 2.8 (95% confidence interval -C.I. 1.3–6.2; chi-square test, p=0.008).

Conclusions

Vaginal vault cytology with cytobrush turned out to better perform than the traditional Ayre’s spatula to obtain an adequate sampling in gynecological cancer patients.  相似文献
