CN201005670Y - Gastroscope with saccule - Google Patents

Abstract

The utility model relates to the technical field of medical instrument, in particular to a gastroscope with a saccule. When patients are taken biopsy and therapy of esophagus, inaccurate materials drawing and occurrence of complication are often resulted from relation changing between the front end of the gastroscope and the target position due to crawling of the gastroscope. In extension or support operations of gastroscope, cardia and pylorus, a plurality of steps such as indwelling guiding threads, pulling out the gastroscope, inserting the saccule or bougienage again are in need, thereby resulting in much pain to the patients. The technical scheme of the utility model is that an inflatable saccule is sleeved above the front end portion of the gastroscope, an air passage is connected to the saccule for providing into a flexible conduit of the gastroscope. The end of the air passage extends out of the flexible conduit below a flexible verifying of the operational portion of the gastroscope and is connected to a gas injection hole. The utility model is adaptable for usage of medical inspection and therapy.

Description

The gastroscope that has sacculus

One, technical field:

This utility model relates to the medical apparatus technical field, a kind of specifically gastroscope that has sacculus.

Two, background technology:

At present, hospital usually becomes the relation of gastroscope front end and target location owing to esophageal peristalsis when doing esophagus biopsy and treatment to the patient, causes drawing materials inaccurate because of position change sometimes or the generation complication.When the expansion of making esophagus, cardia, pylorus or support implantation surgery, often need to keep somewhere seal wire, extract gastroscope, insert a plurality of steps such as sacculus or bougienage device once more.The patient is often agonizing.

Three, summary of the invention:

The purpose of this utility model provides a kind of gastroscope that has sacculus, to overcome above-mentioned defective.The technical solution of the utility model: inflatable balloon of suit above gastroscope elder generation end, the flexible metal conduit close adhesion of the two ends of sacculus and gastroscope, be connected with an air flue on the sacculus, in the flexible metal conduit of gastroscope is inserted at the suit position, the end of air flue stretches out outside the flexible metal conduit below gastroscope operation biopsy hole partly, connects injecting hole.

The diameter of sacculus is at 14mm-18mm, and length 5cm-8cm, balloon material palpus adopt low conforming materials (this material of the many employings of the sacculus of medical apparatus), are close on the shank when last gas injection.The injecting hole of sacculus can connect syringe or Pressure gauge.

The utility model has the advantages that: 1, can rise and support and fixation, particularly when doing sclerotherapy for esophageal varices and ligation treatment, because the wriggling of esophagus, patient's respiratory movement is aimed at and is determined that position influence is very big.This moment inflation makes air bag expansion, and fixedly gastroscope and support esophageal lumen in expansion state is beneficial to the doctor and operates.2, dilating effect can be played, when the benign and malignant stenosis of esophagus, cardia, pylorus occurring, patient's feed and gastric emptying can be influenced.Usually need expand and (or) support inserts.Use the sacculus gastroscope once to finish, reduce a plurality of steps, shortened treatment time, alleviated the patient suffering checking with expansion.3, the esophagus that hemostasis by compression, a variety of causes cause is hemorrhage, and particularly esophageal varices bleeding when carrying out emergency treatment scope lower hemostasia, can directly be inflated, and makes the balloon expandable hemostasis by compression; And effectively cooperate follow-up hemostatic treatment to operate.

Four, description of drawings:

Fig. 2 is a structural representation of the present utility model

Five, the specific embodiment:

From Fig. 1,2 as can be known, an inflatable balloon of (5) suit (1) above gastroscope elder generation end, the flexible metal conduit close adhesion of the two ends of sacculus and gastroscope, be connected with an air flue (3) on the sacculus, in the flexible metal conduit of gastroscope is inserted at the suit position, the end of air flue partly stretches out outside the flexible metal conduit below, biopsy hole of (4) in the gastroscope operation, connects injecting hole (2).

The diameter of sacculus is at 16mm, and length 6cm, balloon material palpus adopt low conforming materials (this material of the many employings of the sacculus of medical apparatus), because this material has certain elasticity, be sleeved on top, gastroscope elder generation end, when last gas injection, be close on the shank the partial diameter of not obvious increase gastroscope.The injecting hole of sacculus can connect syringe or Pressure gauge.

Claims (2)

1. gastroscope that has sacculus, it is characterized by: an inflatable balloon of (5) suit (1) above gastroscope elder generation end, the flexible metal conduit close adhesion of the two ends of sacculus and gastroscope, be connected with an air flue (3) on the sacculus, in the flexible metal conduit of gastroscope is inserted at the suit position, the end of air flue partly stretches out outside the flexible metal conduit below, biopsy hole of (4) in the gastroscope operation, connects injecting hole (2).

2. a kind of gastroscope that has sacculus as claimed in claim 1 is characterized by: the diameter of sacculus is 14mm-18mm, length 5cm-8cm.
