Embodiment Construction

[0013] As can be seen from the figures, the device comprises a substantially cylindrical tube 1 having the function of a retractor, closed at its terminal end 101 suitably tapered and curved. The circle, on the contrary, is open on the starting end (external opening 201 ) which has a conical shape and flares outwards. By way of example only, the body 1 may have an outer diameter in the range between 2.5 and 3.5 cm, for example about 3 cm, and may have a typical length between 10 and 12 cm, including the flared end (external opening 201) , the flared end (external port 201) is only about 2 cm long. It should be understood, however, that the device may vary in size and that they may vary from the indicated dimensions in order to comply with different application requirements. The tapered end (external opening 201) protrudes outwards with a substantially triangular pattern 301 having a length of several centimeters and a longitudinal and The channel-shaped ribs 401 , which are ...

Abstract

The invention describes a disposable device for operations on the arteria haemorroidalis, which comprises a retractor tube ( 1 ), closed and rounded on the end ( 101 ) which is inserted in the anal cavity, and open and diverging on the external end ( 201 ) to which is connected a griping handle (M) which removable houses a luminous source (F). In the connection zone of the handle to the external mouth of the retractor there is provided a channel (C) which contains a parabola ( 5 ) which reflects the light supplied from said luminous source (F) and which sends the reflected light inside of the same retractor, to illuminate a lateral window ( 8 ) through which appears the rectal mucosa upon which the operation must be made for the ligature of the arteria haemorroidalis. The haematic flow of the arteria haemorroidalis and the same artery are detected with precision by means of an ultrasonic probe removably housed in a longitudinal chamber ( 10 ) provided at the interior of the retractor tube, aligned to said window ( 8 ), opened on the mouth ( 201 ) of the same retractor and also provided with a lateral opening ( 7 ) to allow to the sensor of the probe to touch the anal mucosa. The probe is preferably protected in a thin, disposable and easily removable sterilised sheath, to allow the hygienical re-utilization of the same probe.

Description

technical field [0001] The present invention relates to a retractor for surgical operations on the rectal artery. Background technique [0002] For outpatient procedures on hemorrhoids without anesthesia, it is known to use the device described in US Patent No. 5 570 692, which comprises a retractor tube inserted into the anal cavity Closed on the middle end and open on the outer end, said outer end is provided with a gripping handle. The retractor tube is provided with an ultrasound probe on its side wall at a short distance from its closed end to detect blood flow in the rectal artery, and a lateral window near the probe through which the required probe can be detected and observed. The portion of the anal mucosa that is operated on is used to ligate the above-mentioned artery, for example, by a curved needle or by cautery. The closed end of the retractor tube may be illuminated by an illumination source housed in said end and connected to a feed mechanism provided in th...
