Abstract
Description
Technical Field
[0001] The invention relates to the technical field of small enteroscopes, and in particular to an adjustable pulley fixer for an outer sleeve of an airbag-assisted small enteroscope. Background Art
[0002] The small intestine is the longest section of the digestive tract and is an important organ for digestion and absorption. Due to the long, free, and tortuous lumen of the small intestine, conventional gastroscopy can only reach the duodenal papilla and cannot reach the small intestine. The small intestine is the longest organ in the human digestive system, which can reach 5-7 meters. It "occupies" the middle and lower abdomen of the human body in a tortuous way and is the main part of food digestion and absorption. However, the causes of small intestinal diseases are complex, the onset is hidden, the symptoms and signs are atypical, and traditional examination methods are limited. The diagnosis rate has always been low, and it is often equated with "difficult and complicated diseases." Many patients with small intestinal diseases have prolonged illness, which seriously affects their quality of life.
[0003] Enteroscopy is an important means of diagnosing and treating small intestinal lesions. It can be divided into double-balloon electronic enteroscopy (DBE) and single-balloon electronic enteroscopy (SBE). The most important advantage is that it can penetrate deep into the small intestine that ordinary gastroenteroscopes cannot reach, observe local lesions, and take biopsies, remove polyps, treat local lesions, etc., and can perform treatment while diagnosing.
[0004] Enteroscopes mainly include push-type enteroscopes, balloon-assisted enteroscopes (BAE) and spiral enteroscopes. BAE is the most widely used enteroscope in clinical practice, including single-balloon enteroscopes (SBE) and double-balloon enteroscopes (DBE). In 2001, Japanese endoscopist Hironori Yamamoto first reported the use of DBE for full small bowel examination. In 2007, SBE officially entered clinical application. BAE is usually performed by two people, assisted by an endoscopist and an assistant. However, like two-person colonoscopy, two-person BAE has certain problems in terms of ease of operation and safety.
[0005] The two-person operation problem is as follows:
[0006] 1. High manpower demand: Two-person operation requires the collaboration of two medical staff, one responsible for operating the endoscope and the other responsible for assisting and operating peripheral equipment, which increases the demand for human resources.
[0007] 2. Difficulties in operational coordination: Operation between two persons requires a high degree of collaboration and tacit understanding. If the coordination is improper, the safety and efficiency of the operation may be affected.
[0008] 3. High cost: Since two medical staff are required to participate, the cost of double enteroscopy operation is high, which increases the manpower and financial burden of medical institutions.
[0009] 4. Limited operating space: Two-person operation may be limited by the operating space, especially in the small endoscopic operating room environment, where two people operating at the same time may seem cramped and inconvenient.
[0010] 5. Training is difficult: Two-person operation requires medical staff to undergo professional training to achieve good collaboration, and training and learning are difficult. Summary of the invention
[0011] The purpose of the present invention is to provide an adjustable pulley holder for the outer cannula of an air-bag-assisted enteroscope, so as to overcome the problems existing in the background technology, further promote the popularization of enteroscopes, especially reduce labor costs, and improve surgical efficiency (the holder can replace assistants, and the number of surgeons is reduced from 2 to 1).
[0012] In order to achieve the above-mentioned purpose, the technical solution of the present invention provides an adjustable pulley fixture for the outer sleeve of a balloon-assisted small enteroscope, comprising a bed edge fixing device that can be installed on the edge of a bed, a movable adjustable bracket arranged on the bed edge fixing device, and an outer sleeve fixture arranged on the movable adjustable bracket, wherein the outer sleeve fixture is provided with a sliding module that can fix the outer sleeve.
[0013] Preferably, the outer sleeve holder comprises a slide rail arranged on the movable adjustable bracket, and the slidable module is arranged on the slide rail and can adjust the position.
[0014] Preferably, the outer sleeve fixer is provided with a movable lock which can fix the slidable module on the slide rail.
[0015] Preferably, the movable adjustable bracket can adjust the height and / or angle of the outer tube fixture relative to the bed edge fixture.
[0016] In summary, the present invention includes the following beneficial technical effects:
[0017] With the development of enteroscopic technology, more medical institutions are gradually carrying out enteroscopic examinations and treatments. This invention can further promote the popularization of enteroscopic technology and is expected to be transformed into clinical practice. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] The embodiment of the present invention discloses an adjustable fixer for an overtube of an air-bag-assisted small enteroscope, which is composed of several parts:
[0023] 1. Bed edge fixing device 1: The bed edge fixing device 1 can be fixed to the edge of the examination bed according to different examination parts, patient positions, examination beds, examination room environments and other factors;
[0024] 2. Movable adjustable bracket 2: adjust the height and angle of the fixator according to the examination site and the surgeon's needs;
[0025] 3. Outer tube holder 3: There is a sliding module (movable module) under the outer tube holder 3. When it reaches the appropriate position, there is a movable lock on the right side to fix the module position. When the operator needs to push the small intestinal endoscope, the outer tube position remains unchanged and the pulley module position can be locked; when the operator needs to pull the outer tube, the pulley module lock can be loosened to change the module position at any time.
[0026] Instructions for use: Fix the adjustable holder of the balloon-assisted enteroscope (BAE) outer tube to the examination bedside. After the balloon enteroscope enters the body, the operating physician can fix the outer tube to the sliding module and freely adjust the position of the sliding module according to the depth of the endoscope. If endoscopic treatment or operation is required, the sliding module can also be locked on the slide rail to play a fixing role. When adjustment is required, the sliding module can be released.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
