Description

The invention relates to medicine and can be used for endoscopic studies and treatment of the rectum and lower sigmoid colon.

Sigmoidoscopy is a mandatory type of examination of a patient who has turned to a proctologist for help. It is carried out after a preliminary digital examination of the rectum, to exclude diseases that make the procedure dangerous or impossible (strictures and deformations of the rectum). In the knee-elbow position, the rectoscope is inserted into the rectum of the patient and allows you to examine it and part of the sigmoid colon. The procedure is performed without pain relief.

The Fedorov Rectoscope is one of the first samples of a sigmoidoscope, which was a set of metal tubes of various lengths and diameters equipped with obturators and a light source. A classic rectoscope is a metal hollow tube 20-30 cm long, which is connected to a illuminator using a flexible light guide. Proctoscopes with and without obturators are known.

Known rectoscope containing a tube placed in it with a light guide and a tip. The distal end of the tip is rounded, with a central hole for placement of olive. The hole diameter is 0.2 mm larger than the olive diameter (Pat. No. 2108740 of the Russian Federation. IPC A61B 1/31. Rectoscope. Kurdyshev Yu.A. et al. / Kvarts-Ltd. Publish. 04.20.1998).

A known rectoscope containing a housing with a light guide and a tube equipped with a tip, the end part of which is cut at an angle to the axis of symmetry of the tube, and the formed section has streamlined edges and tongue (Pat. No. 2215462 RF. IPC A61B 1/06, 1/31. Rectoscope (Variants). Lutsenko S.N. et al. / Scientific Production LLC. Quartz Firm Publ. 10.11.2003.).

Additional opportunities for conducting a sigmoidoscopy are provided by the latest development - a bezobturatorny rectoscope with a beak-shaped tip of Zarezaev. This device allows you to visually control the process of introducing the tube from the very beginning of the procedure. With its use, the risk of injury to the rectal mucosa during administration and manipulation in the rectum is reduced. This is especially important in the presence of low located neoplasms of the rectum. The absence of the need to remove the obturator reduces the likelihood of additional contamination of the research working field.

OOO Quartz Research and Production Company produces several modifications of rectoscopes: with a fiber optic waveguide and an obturator, with a biopsy channel Re-VS-2.8 / 20 Quartz, with a fiber optic fiber without an obturator Re-VS-20 / bo Quartz , with fiber optic fiber and obturator Re-VS-20 “Quartz”.

A known rectoscope with a fiber waveguide and an obturator Re-BC-20 "Quartz", which consists of a tube 1 with an obturator 2, a lighter 3, consisting of a light guide cable 4 and a light guide 5, an optical device 6, a pneumatic supercharger 7, a protective cover 8 (Fig. .one). Tubes vary in length of the working part, the design of all tubes is the same. The tube 1 consists of an outer and inner tube, between which there is a fiber guide 5. On the outer surface of the tube 1 there is a scale with numbers to determine the depth of introduction of the rectoscopic tube. Each tube 1 is equipped with an obturator 2, the corresponding length. Obturators serve to ensure the safe introduction of the tubes into the rectum and to protect the tubes from contamination during administration. The obturator is a rod, at one end of which a protective cover 8 or optical device 6 is attached. The light guide cable 4 serves to transmit the light flux from the illuminator to the tube 1. On the tube 1, the cable 4 is attached with a lock.

The optical device 6 serves to inspect the mucosa under magnification. The protective cover 8 provides sealing of the rectoscope and prevents the doctor from getting intestinal contents on him during the examination. Pneumatic supercharger 7 is used to pump air into the cavity under study. It is a rubber cylinder connected to the tube 1 with the help of a rubber tube 9, put on the crane through the adapter 10 (Rectoscope with fiber optic fiber and obturator Re-VS-20 “Quartz” Passport. KLShR 944210.005 PS. - Saratov, 2002, 18 sec. .). This rectoscope is selected for the prototype. The disadvantage of this design is that the pneumatic supercharger 7 creates great inconvenience to the doctor during sigmoidoscopy, since one arm is constantly occupied.

The objective of the invention is to increase diagnostic capabilities and simplify sigmoidoscopy, reducing the time of the study.

The technical result consists in providing the ability to maintain the necessary for inspection of the lumen of the rectum and sigmoid colon, improving operating conditions, reducing the time of the study.

This is achieved due to the fact that an air compressor with a capacity of 200 l / h is used as an air blower, which, together with the illuminator, is connected in parallel to a power source.

Using an air compressor releases the doctor’s hand, and he has the ability to palpate the rectum of the patient to bring the rectum to the tube of the rectoscope, which greatly simplifies the procedure and reduces the time of the study, especially during mass examinations. During a sigmoidoscopy, the doctor pinches the tube from the air compressor as needed with the thumb of the working hand and stops the air supply. In addition, the air compressor easily provides the necessary lumen of the rectum and sigmoid colon, which

allows inspection, both at the stage of introduction of the tube, and at the stage of its removal, which increases the diagnostic capabilities. A classic examination is performed in the knee-shoulder or knee-elbow position, while "when the tube is inserted, a detailed examination is not carried out, but they only try to bring the tube to the end as painfully as possible (Rivkin V.L. et al. Guide to Coloproctology, M 2004 , p. 38). Sigmoidoscopy is performed without an obturator, which saves time for removal and disinfection of the obturator.

The proposed rectoscope (figure 2) includes a tube 1 having an outer and an inner tube, between which a light guide 5 is located. At the distal end of the tube 1, the light guide 5 is distributed in the form of a ring. At the proximal end of the tube 1, the optical fiber 5 is mounted in the fitting for connection to the light guide cable 4. Replaceable nodes (protective cover 8 and the optical device 6 are mounted on the proximal end of the tube 1 using a bayonet lock). An air compressor is used as a pneumatic supercharger 7, which, together with the illuminator 3, is connected in parallel to a power source. The proposed rectoscope is used as follows: the rectoscope assembled with the protective cover 8 on is attached closely to the perianal zone with simultaneous air supply (usually 2-3 seconds) during which the anal canal is easily opened, which allows a 1-tube to be carried out freely, painlessly and atraumatically. anal canal and further into the rectum and sigmoid colon; the patient’s position is on his back in a gynecological chair with legs brought to his stomach; if necessary, the air supply tube from the pneumatic supercharger 7 (air compressor) is pressed with the thumb of the right hand, which prevents excessive insufflation of air, after which a diagnostic examination of the intestinal mucosa is carried out, and

if necessary, to carry out manipulations or a detailed examination under magnification, remove the protective cover 8 or change to an optical device 6. At the end of the study, remove tube 1 from the intestine; at the same time, turning off the illuminator 3, turn off the pneumatic supercharger 7 (air compressor). Sigmoidoscopy is performed in a gynecological chair in a supine position with legs brought to the abdomen, which allows palpation of the abdomen with your free hand, eliminates the so-called “fecal shower”, saves medical staff time, as it allows you to immediately proceed to the examination from the initial examination of the patient, not changing the position of the patient.
