STRUCTURAL ARRANGEMENT APPLIED TO A RIGID ENDOSCOPE FOR CLEANING THE OBJECTIVE LENS DURING VIDEO SURGERY PROCEDURE

Abstract

The present utility model is related to the medical field, and more specifically to a new arrangement applied to rigid endoscopes (1), which comprises the arrangement of two channels superior upper (3) and lower (4) longitudinally arranged on the rigid shaft (11) of the endoscope (1), with the upper channel (3) receiving a piece of equipment (5) on its proximal end capable of releasing, in a controlled way, an amount of crystalloid solution, which is directed by gravity to the distal end (12), lubricating the objective lens of the endoscope, and with the lower channel (4) connected to suction device (7), through a hose (43) with valve (8), which when activated, sucks the saline, cleaning the lens (2) during the video-surgery procedure, removing blood or body secretions, and improving the visibility of this procedure for the surgeon.

Claims

1) “CONSTRUCTIVE ARRANGEMENT APPLIED IN RIGID ENDOSCOPE FOR CLEANING OF OBJECTIVE LENS DURING VIDEO-SURGICAL PROCEDURE”, aimed to clean the objective lens (2) of rigid endoscopes (1) during video-surgery procedure, with the rigid shaft (11) characterized to provide two independent longitudinal channels, one of them (3) arranged on the upper part, and the other (4) arranged on the lower part, both of them with access to the distal end of the endoscope (1) where is located the objective lens (2), and the upper channel (3) provides advanced access (33) and the lower channel (4) provides backed off access (44) in relation to the objective lens (2); the upper channel (3) provides on its proximal end a upper access (31) to a saline equipment (5) and the lower channel (4) has in its proximal end an access (41) where is fixed a connector (42) coupled to a hose (43), provided with activation valve (8), connected to suction device (7).

Description

DESCRIPTION OF THE FIGURES

[0015] The abovementioned arrangement for cleaning the endoscope during video-surgery, object of protection of the present claim, will be explained in details by using the figures attached herein, where:

[0016] FIG. 1 shows a side view of the application of device for cleaning of the objective lens in a rigid endoscope;

[0017] FIG. 2 shows a magnified detail in perspective of the distal end and the fore end of the endoscope in a first constructive version;

[0018] FIG. 3 shows a magnified detail in perspective of the distal end and the fore end of the endoscope in a second constructive version;

DETAILED DESCRIPTION OF THE MODEL

[0019] As shown in FIG. 1, the new arrangement applied on rigid endoscope (1) for cleaning of the objective lens (2), is comprised by two independent longitudinal channels developed along the rigid shaft (11) of the endoscope (1), with one channel (3) arranged on the upper part and the other channel (4) arranged on the lower part, both of them with access to the distal end of the endoscope (1).

[0020] The distal end (12) of the endoscope (1) is developed in acute angle in order that the upper channel (3) configure a more advanced access (33) and the lower channel (4) configure a backed off access (44) in relation to the objective lens (2).

[0021] The upper channel (3) has on its proximal end an upper access (31) where it is affixed a connector coupled to a hose (32) of a saline equipment (5), containing flow control tap (51), which is capable of releasing, in a controlled way, an amount of crystalloid solution that is directed by gravity through the saline bag (52) to the distal end (12) of the endoscope (1), lubricating the objective lens (2).

[0022] The lower channel (4) has in its proximal end a lower access (41) where it is fixed a connector (42), coupled to a hose (43), provided with activation valve (8), and that is connected to a suction device (7), which when actuated sucks the saline (S) from the distal end (12) of the endoscope (1), previously released by the access (33) of the upper channel (3), removing blood or body secretions, and consequently cleaning the lens (2) during video-surgery procedure.
