Description
Technical field
This utility model relates to gastroscope operation protector field, particularly relates to a kind of bite-block inflated type gastroscope casing.
Background technology
The gastroscope operation of present stage; most is directly insert gastroscope to carry out operation technique; although this simple mode is convenient and swift; but patient has larger pain; when especially sharp keen foreign body being taken out for employing gastroscope removal surgery, usually can damage mucous membrane of esophagus, sometimes even cause perforation of esophagus; as do not performed the operation in time, severe patient entail dangers to life.
A kind of gastroscope protective sleeve domestic at present, needs to be bundled in gastroscope front end, repeatedly enters bottleneck throat with gastroscope; because quality is soft, for needing the operation repeatedly passing in and out gastroscope, not there is protective effect; in addition, also easily punctured by foreign bodies such as sharp keen metals, and then infringement esophagus.
Also have some gastroscope protective sleeves, structure is simple, and end does not have supporter, and in operation process, patient Chang Yin operating time is long, chokes and coughs the phenomenon with the landing of trocar sheath wriggling.
Summary of the invention
The technical problems to be solved in the utility model how to overcome the deficiencies in the prior art, provides one that esophagus can be protected injury-free, alleviate misery during corrective surgery, easily enters esophagus, convenient fixing gastroscope casing.
The scheme that this utility model adopts for achieving the above object is: a kind of bite-block inflated type gastroscope casing, comprise trocar sheath, bite-block, connecting band, rubber ring, described trocar sheath lower end is ramped shaped, the length of described trocar sheath is 17cm, described trocar sheath comprises hard sleeve and soft tube, the diameter of described soft tube is greater than described hard sleeve, it is outside that described silicon case casing is contained in described hard sleeve, spiral type inflating rubber pipe is provided with between described soft tube and described hard sleeve, described bite-block is cylindrical, described bite-block is connected with described trocar sheath by connecting band, described bite-block is enclosed within outside outside described rubber ring, rubber tube one end is provided with gas-filled switching tube, described gas-filled switching tube is arranged on described bite-block side.
Further: the material of described trocar sheath is transparent flexible plastics.
Further: it is outside that described rubber tube is evenly wrapped in described hard sleeve.
Further: described rubber ring is oval.
Further: described soft tube is flexible.
Further: described bite-block upper end is provided with can overlap overhead cord.
The utility model has the advantage of and greatly can alleviate the pain of patient when gastroscope operation, end is adopted to be the trocar sheath of ramped shaped, easily enter esophageal patient, adopt hard sleeve, the mode that soft tube and rubber tube combine, can effectively avoid sharp keen foreign body to the damage of esophagus, have employed gripper pad structure, can be inflated by rubber tube, esophageal patient can be expanded, be conducive to the success rate improving operation, the frequent wriggling of trocar sheath in operation process and landing can also be avoided, of the present utility model be also advantageous in that do gastroscope anesthesia under related surgical time, conveniently enter mirror, the damage brought because repeatedly entering mirror can be reduced.
Accompanying drawing explanation
Fig. 1 this utility model overall structure schematic diagram.
Detailed description of the invention
A kind of bite-block inflated type gastroscope casing, as shown in Figure 1, comprise trocar sheath 1, bite-block 2, connecting band 3, rubber ring 4, described trocar sheath 1 lower end is ramped shaped, the length of described trocar sheath 1 is 17cm, described trocar sheath 1 comprises hard sleeve 11 and soft tube 12, the diameter of described soft tube 12 is greater than described hard sleeve 11, it is outside that described soft tube 12 is sleeved on described hard sleeve 11, spiral type inflating rubber pipe 13 is provided with between described soft tube 12 and described hard sleeve 11, described bite-block 2 is cylindrical, described bite-block 2 is connected with described trocar sheath 1 by connecting band 3, described bite-block 2 is enclosed within outside outside described rubber ring 4, rubber tube 13 one end is provided with gas-filled switching tube 131, described gas-filled switching tube 131 is arranged on described bite-block 2 side.
The material of described trocar sheath 1 is transparent flexible plastics, it is outside that described rubber tube 13 is evenly wrapped in described hard sleeve 11, and described rubber ring 4 is oval, and described soft tube 12 is flexible, described bite-block 2 upper end is provided with can overlap overhead cord 21, is fixed on head and forms a kind of constraint.
Using method of the present utility model is, after this utility model is sterilized by operator, hand-held bite-block 2, slowly put into patient's pharyngoesophagus, below pharyngoesophagus 2cm is inserted to from oral cavity front tooth, patient teeth is made to bite bite-block, and make rubber ring 4 be placed in patient's lip top, then cord 21 being enclosed within patients head is formed fixing, by being placed in the gas-filled switching tube 13 of bite-block 2 side, slowly toward inflation in rubber tube 13, be fixed in esophageal patient until whole trocar sheath 1 expands, last operation person just can carry out gastroscope operation.
Above-described embodiment, just in order to technical conceive of the present utility model and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.The change of every equivalence done by the essence of this utility model content or modification, all should be encompassed in protection domain of the present utility model.
