Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of digestive tract endoscopy, more specifically, relates to a positioning device for digestive tract lesion endoscopy. BACKGROUND

[0002] The digestive tract endoscope is a core minimally invasive instrument for clinical diagnosis and treatment of digestive tract diseases. It can help doctors to intuitively observe the mucosa state and timely find polyps, ulcers, inflammation, tumors and other lesions by inserting a flexible pipe with an imaging module and an operation channel into the esophagus, stomach, colon and other digestive tract cavities, and transmitting internal images in real time with the help of a front-end camera. Meanwhile, it can complete a series of diagnosis and treatment operations such as lesion tissue sampling, polyp resection, bleeding point hemostasis and mucosa stripping by carrying biopsy forceps, electric knives and other instruments through the operation channel.

[0003] Chinese patent publication No. CN120052972B discloses a digestive tract endoscope specimen collection device. The cutting assembly in the invention can cut and collect specimens while sealing and preserving them. Pulling the first traction rope outward will pull the control plate connected to the free end of the first traction rope, causing the cutting knife to cut the specimen. At the same time, the specimen is directly preserved in the collection cylinder, and the clamping assembly can clamp the specimen and take it out.

[0004] The existing digestive tract lesion endoscope has the following shortcomings when in use: The internal structure of the digestive tract is complex, with natural folds in the stomach wall and uneven intestinal mucosa. Moreover, the digestive tract morphology of different patients has significant individual differences. The existing endoscope support structure is often single and cannot adaptively adjust according to the different positions and shapes of the mucosa, making it difficult to effectively fit the mucosa around the lesion during actual operation, and the support pressure cannot be evenly distributed.

[0005] The mucosa surface of the digestive tract is moist and has mucus, and the existing fixation method has defects. Due to the special environment of the mucosa surface, it is easy to fall off, resulting in positioning failure. Although the rigid fixation structure can ensure a certain stability, it may cause damage to the fragile mucosa, such as scratches and bleeding, causing great pain and potential risks to the patient.

[0006] Therefore, the existing structure and defects are improved to provide a positioning device for digestive tract lesion endoscopy, so as to achieve the purpose of having more practical value. SUMMARY

[0007] To solve the above technical problems, the present application provides a positioning device for digestive tract lesion endoscopy to solve the problem that the existing positioning device lacks stable multi-point support structure, resulting in large positioning deviation, and the support structure is mostly fixed in shape and cannot adapt to the complex environment of the uneven digestive tract.

[0010] Preferably, a rubber disc is fixedly installed at the circumferential end of each suction cup, and a micro-prick head is fixedly installed at the side end of each rubber disc.

[0011] Compared with the prior art, the present application has the following beneficial effects: In the present application, the protective hollow column can accommodate and wrap the supporting mechanism such as the first adjusting tube, so as to avoid the supporting mechanism from scratching and colliding with the mucosa of the digestive tract during movement, reduce the risk of mucosa damage and the discomfort of the patient, the doctor can control the retreat distance of the protective hollow column through the pull rope, flexibly control the unfolding range of the first adjusting tube according to the space size of the lesion site, avoid touching the surrounding normal tissues due to too large unfolding angle, or cannot cover the lesion due to too small unfolding angle, and make the unfolding of the supporting mechanism more in line with the actual operation requirements.

[0012] In the present application, by setting the umbrella type support structure composed of the first adjusting pipe, the second adjusting pipe and the universal joint, the actual internal digestive tract is not a flat environment, the stomach wall has natural wrinkles, the intestinal mucosa has ups and downs, and the digestive tract morphology of different patients has individual differences, the multi-point support design of the umbrella type structure can make multiple support points respectively adhere to the mucosa at different positions around the lesion, and the angle of the universal joint is self-adaptively adjusted, so that each support point can form effective contact with the mucosa, disperse the support pressure, reduce the risk of positioning deviation caused by intestinal peristalsis or slight movement of the endoscope, and better adapt to the complex internal environment of the digestive tract.

[0013] In the present application, by setting the cooperation structure of the protection hollow column and the embedded groove, in the early exploration stage of actual digestive tract detection, the support mechanism does not need to be started, at this time the protection hollow column slides forward, the first adjusting pipe is stored in the embedded groove, the occupied space of the front end of the endoscope pipeline is greatly reduced, which is helpful for the endoscope to smoothly pass through the esophageal entrance, the colon bend and other narrow parts, and reduces the operation difficulty; when the lesion needs to be positioned, the support mechanism is released by the protection hollow column backtracking, and after unfolding, it can cover the area around the lesion, which does not affect the vision and movement flexibility in the early exploration stage, and can also meet the subsequent positioning requirements.

[0014] In the present application, by setting the telescopic cooperation structure of the first adjusting pipe and the second adjusting pipe, in actual detection, the position depth of the lesion and the distance between the lesion and the endoscope probe are different, for example, the superficial lesion is close to the mucosa surface, the small deep lesion needs to be accurately approached, and the mucosa around the same lesion may have different height differences, through the control of the gas injection pipe, the shunt and the air pump, the telescopic length of each second adjusting pipe can be adjusted individually, so that the support mechanism can flexibly adjust the support distance according to the actual position of the lesion, and ensure that each suction cup and micro spike head can accurately adhere to the corresponding support point, thereby providing more suitable positioning assistance for lesion sampling, electrocoagulation and other treatment operations.

[0015] In the present application, by setting the cooperation structure of the suction cup and the micro spike head, the mucosa surface of the actual digestive tract is wet and has mucus, simple adsorption type fixation is easy to fall off due to poor sealing, and rigid fixation structure may damage the fragile mucosa, the suction cup can adhere to the wet mucosa surface to form initial adsorption fixation, the rubber disc further enhances the sealing effect, and the micro spike head has anti-skid effect, the micro spike head is short in length and has a rounded tip, will not penetrate the mucosa surface layer, only enhances the fixation stability through friction, can effectively prevent positioning displacement when shear force is generated by intestinal peristalsis, and avoids causing damage such as scratches and bleeding to the mucosa, so as to balance the positioning reliability and operation safety, and reduce postoperative discomfort of the patient.
