Embodiment Construction

[0037] For illustrative purposes, a Cusco-type speculum is shown in the figure. Those skilled in the art will understand that the present invention is not limited to this speculum, but is applicable to any type of speculum having mechanical means suitable for dilating the vagina to enable visualization of the tissues making up the female lower genital tract.

[0038] figure 1 Illustrated is a Cusco-type speculum having two pallets (1, 2) interconnected by means of a pivot joint (3) positioned at the rear of the pallets. Each pallet engages with a corresponding handle (4, 5) by means of a pin (6). The separation distance between the handles (4, 5) becomes greatest when the fronts of the pallets (1, 2) are in contact. For the comfort of the patient, the blades are in or near contact with each other when the speculum is inserted into the vagina. After insertion, the handles (4, 5) are brought closer to each other, thereby separating the trays (1, 2) and dilating the vagina. T...

Abstract

A vaginal speculum arrangement includes a blade system for opening the vagina having a first blade (1) and a second blade (2) physically separable from one another, and an injection mechanism for dispensing a diagnostic marker onto the surface of the examined tissue having an injection probe (7). The direction of application of the diagnostic marker by the injection probe is not influenced by separation of the first and second blades and thus the injection probe (7) allows for a substantially homogeneous application of the diagnostic marker on a desired area in the examined vaginal or cervical tissue, irrespective of the degree of separation of the blades (1,2). The probe may be a nozzle generating a desirable injection pattern. The probe may be affixed to an extension rod, which may be mechanically coupled with the speculum blades. Optical, electronic imaging means, illumination means and treatment tools may be mounted onto the extension rod, which rod may be reversibly attached to mechanical positioning systems or to imaging devices used in colposcopy. The speculum arrangement may be used as a tool for diagnostic and screening examinations and for the treatment of cervical and vaginal neoplasias.

Description

technical field [0001] The present invention relates to medical instruments, in particular to speculums. More specifically, the present invention relates to a vaginal speculum incorporating an applicator for uniform delivery of a standardized dose of a liquid diagnostic indicator over the female lower genital tract. Background technique [0002] Detection and identification of lesions of the female lower genital tract (cervix, vagina) involves a series of medical procedures including screening tests (Pap test), microscopic examination of histology (colposcopy), biopsy, and histology. An abnormal Pap test is followed by a colposcopy, in which the vagina is opened with the aid of a speculum to allow visualization of the tissue with a microscope. In colposcopy, a small diagnostic indicator is applied topically, which changes the optical properties of the tissue depending on the pathology. Specifically, application of a 3-5% acetic acid solution causes reversible whitening of ...
