Description

Technical Field

[0001] This utility model relates to the field of enteroscopy technology, and in particular to an adjustable pulley fixator for the outer tube of an enteroscopy. Background Technology

[0002] The small intestine is the longest segment of the digestive tract and a vital organ for digestion and absorption. Due to its long, free, and tortuous lumen, conventional gastroscopy, which only reaches the duodenal papilla, cannot reach the small intestine itself. Reaching 5-7 meters in length, the small intestine meanders through the lower abdomen and is the primary site for food digestion and absorption. However, small intestinal diseases are complex in etiology, have insidious onset, and present with atypical symptoms. Combined with limitations in traditional diagnostic methods, the diagnostic rate has historically been low, often equating with "difficult-to-diagnose" diseases. Many patients with small intestinal diseases experience prolonged illness, severely impacting their quality of life.

[0003] Enteroscopy is an important tool for diagnosing and treating small bowel diseases. It can be divided into dual-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE). Its most important advantage is that it can reach deep into the small intestine that ordinary gastroscopes and colonoscopes cannot reach, observe local lesions, and at the same time take biopsies, remove polyps, and treat local lesions, thus allowing for diagnosis and treatment simultaneously.

[0004] Small bowel endoscopy mainly includes the pushing enteroscopy, balloon-assisted enteroscopy (BAE), and spiral enteroscopy. BAE is currently the most widely used enteroscopy in clinical practice, including single-balloon enteroscopy (SBE) and double-balloon enteroscopy (DBE). In 2001, Japanese endoscopist Hirotoku Yamamoto first reported the use of DBE for whole small bowel examination, and SBE officially entered clinical application in 2007. BAE is usually performed by two people, an endoscopist and an assistant. However, like two-person colonoscopy, two-person BAE has certain issues regarding ease of operation and safety.

[0005] The issues with two-player operation are as follows:

[0006] 1. High demand for manpower: Two-person operation requires two medical staff to work together, one to operate the endoscope and the other to assist and operate peripheral equipment, which increases the demand for human resources.

[0007] 2. Difficulty in operation coordination: Two-person operation requires a high degree of cooperation and tacit understanding. If the coordination is not good, it may affect the safety and efficiency of the operation.

[0008] 3. High cost: Due to the need for two medical staff, the cost of a two-person enteroscopy is high, which increases the human and financial burden on medical institutions.

[0009] 4. Limited operating space: Two-person operation may be limited by the operating space, especially in a small endoscopic operating room environment, where two people operating at the same time may feel cramped and inconvenient.

[0010] 5. Training is quite difficult: Two-person operation requires medical staff to undergo professional training to achieve good collaborative results, and the training and learning are quite difficult. Utility Model Content

[0011] The purpose of this invention is to provide an adjustable pulley fixator for the outer tube of a small enteroscope, to overcome the problems existing in the background technology, further promote the popularization of small enteroscopes, especially to reduce labor costs and improve surgical efficiency (the fixator can replace an assistant, reducing the number of surgeons from 2 to 1).

[0012] To achieve the above objectives, the present invention provides an adjustable pulley fixation device for the outer tube of a small enteroscope, including a bed edge fixing device that can be installed on the bed edge, a movable adjustable bracket on the bed edge fixing device, and an outer tube fixation device on the movable adjustable bracket, wherein the outer tube fixation device is provided with a sliding module for fixing the outer tube.

[0013] Preferably, the outer tube retainer includes a slide rail disposed on the movable adjustable bracket, and the slidable module is disposed on the slide rail and its position is adjustable.

[0014] Preferably, the outer tube retainer is provided with a movable latch that can fix the slidable module to the slide rail.

[0015] Preferably, the movable adjustable bracket can adjust the height and / or angle of the outer tube retainer relative to the bed edge fixing device.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] With the development of enteroscopy technology, more medical institutions are gradually carrying out enteroscopy examinations and treatments. This utility model can further promote the popularization of enteroscopy and is expected to be clinically translated. Attached Figure Description

[0019] Reference numerals: 1. Bed edge fixing device; 2. Movable adjustable bracket; 3. Outer tube fixing device, i.e., pulley module. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model discloses an adjustable pulley fixator for the outer tube of a small enteroscope, which consists of several parts:

[0022] 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 sites, patient positions, examination beds, examination room environments, etc.

[0023] 2. Adjustable movable bracket 2: Adjust the height and angle of the fixator according to the examination site and the surgeon's needs;

[0024] 3. Outer Tube Fixer 3: The outer tube fixer 3 is equipped with a sliding module (movable module) at the bottom. When it reaches the appropriate position, a movable lock on the right side is provided to fix the module position. When the surgeon needs to advance the small bowel endoscope, the position of the outer tube remains unchanged, and the position of the pulley module can be locked; when the surgeon needs to pull the outer tube, the pulley module lock can be released to change the module position at any time.

[0025] Instructions for use: Secure the adjustable retainer of the balloon-assisted enteroscope (BAE) outer cannula to the side of the examination bed. After the balloon enteroscope is inserted into the body, the operator can fix the outer cannula to the sliding module and freely adjust the position of the sliding module according to the depth of insertion. If endoscopic treatment or procedures are required, the sliding module can also be locked on the rail for fixation; to adjust, release the sliding module.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
