Problems solved by technology

The inventor found in actual clinical work that the measuring device in the above-mentioned patent needs a certain hardness support, and a relatively thick tube diameter is required to accommodate the balloon device; during the measurement process, the patient has to endure the obvious foreign body sensation in the throat, which is easy to Nausea, vomiting
In addition, in the above-mentioned device, the positions of the upper and lower edge balloons are fixed, and in order to make the upper and lower edge balloons of the measuring device inflate smoothly, the medical staff must repeatedly adjust the degree of the measuring device extending into the throat, otherwise the achalasia section may hinder the balloon swelling; this further exacerbates patient discomfort, prolongs the measurement process, and is prone to damage to the mucosal tissue of the pharynx

Embodiment 1

[0041] In this embodiment, a device for positioning the achalasic segment of the upper esophageal sphincter is provided, as shown in the attached figure 2 As shown, the main body of the positioning device is a guide tube 1-1 with one end closed. The guide tube has a positioning area, and several through holes 1-10 are evenly distributed on the tube wall of the positioning area. Closed with a membrane 1-2, the membrane 1-2 covers all the through holes 1-10.

[0042] The opening end of the positioning area close to the guide tube 1-1 is called the upper edge, and the one close to the closed end of the guide tube is called the lower edge. The injection tube 1-5 extending from the opening end of the tube 1-1, the injection tube 1-5 forms a closed cavity with the positioning area and the film 1-2, and the cavity is not connected to the inside of the guide tube.

[0043] There is also a tube core 1-3 inside the guide tube 1-1, and the tube core 1-3 is located at the central axis o...

Embodiment 2

[0046] In this embodiment, another upper esophageal sphincter achalasic segment positioning device is provided. The difference from Embodiment 1 is that in this embodiment, the positioning device has two positioning areas: upper edge positioning area 2-3 and lower edge positioning zone 2-2.

[0047] Such as Figure 4 As shown, the upper edge positioning area 2-3 and the lower edge positioning area 2-2 are separated by an inner seal 2-13, and the upper edge inner seal 2-13 has a tube extending from an injection tube to a guide tube 2-1 respectively. Mouth. Wherein, the injection tube 2-6 and the upper edge positioning area 2-3 form a closed cavity, and the injection tube 2-5 and the lower edge positioning area 2-2 form a closed cavity, and the two cavities are independent of each other.

Abstract

The invention relates to an upper esophageal sphincter achalasia segment positioning device and a measurement method. Botulinum toxin injection for treating dysphagia has the advantages of being small in trauma and convenient to operate; and the difficulty lies in accurate positioning of achalasia segment muscle. An existing upper esophageal sphincter achalasia segment measuring device usually adopts upper and lower edge positioning balloons for positioning; but the length of an achalasia segment capable of being measured by the positioning mode is limited; furthermore, the structure is complex; the pipe diameter is relatively large; and a patient feels uncomfortable. According to the upper esophageal sphincter achalasia segment positioning device provided by the invention, a more flexible positioning area is arranged; therefore, the measurable range of the positioning device is relatively large; measurement is more flexible; discomfort of the patient is effectively reduced; and the positioning device has good clinical application value.

Description

technical field [0001] The invention belongs to the technical field of muscle positioning and measuring instruments, and in particular relates to a positioning device for achalasia segment of upper esophageal sphincter and a method for measuring the length of achalasia segment. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Dysphagia is a common clinical symptom. Any disease in the passage from the mouth to the stomach can cause dysphagia. According to different etiologies, it can be divided into neurogenic (cerebrovascular accident, craniocerebral trauma, Parkinson's disease, amyotrophic spinal cord disease, etc.) Lateral sclerosis, vagus nerve or recurrent laryngeal ne...
