Abstract
A discharging prevention air flap for medical endoscope outer thimble is provided, which belongs to medical treatment instruments. The utility model is a claming sleeve arranged on the endoscope outer thimble, which is a latex sleeve which can prevent the air overflow from the gap between the outer thimble and the endoscope when the endoscope is discharged. One end of the latex sleeve is a round opening which can be suited with the endoscope outer thimble, the rear part of the other end takes in a shape of taper. The top of the taper is an insertable connection opening. The utility model solves the problem that the air overflows from the outer thimble when the endoscope enters into the human body to be charged. The utility model can store the parts which needs collecting air, which makes the view under the endoscope is completed discovered, and realize convenient and accurate operation. The utility model guarantees the medical treatment condition, and improves the quality of medical treatment greatly.
Description
Technical field
This utility model relates to the anti-exhaust clack of medical endoscope trocar sheath, belongs to medical instruments.
Background technology
In the prior art, medical scope is as gastroscope, intestinal mirror, duodenoscope, peritoneoscope etc., after inserting human body, all need under inflation situation, could expose the visual field of performing the operation, because the construction features of human body itself, that is: UES, anal sphincter etc. have the effect that prevents that gas from effluxing, and once advance the Clinics and Practices that mirror can complete operation, do not need the apparatus that prevents that gas from effluxing.But advance mirror repeatedly for needs and just can reach therapeutic purposes; as: prick esophageal variceal vein, scope carcinectomy early and gastroesophageal some other treatment down with monocycle looping and binding device cover; the intestinal mirror reversal is operated etc. again; and protect human body natural's passage again; usually use the scope trocar sheath in the medical treatment; can directly in trocar sheath, insert when scope enters repeatedly like this, can not damage organization of human body.Though use the scope trocar sheath can reach the convenient purpose of inserting scope in the medical treatment, but all obvious external diameter of existing scope trocar sheath internal diameter greater than endoscope, very big slit is arranged between scope shank and the trocar sheath, owing to do not prevent the structure that gas effluxes, gas was directly discharged from trocar sheath when scope entered behind the human body inflation, can not effectively accumulate in the position that needs pneumatosis, and it is bad to cause the scope downward view to expose, endoscopic technic just can not be accurately, finish smoothly, even cause operation failure.
Summary of the invention
At having problems in the above-mentioned prior art, goal of the invention of the present utility model provides a kind of anti-exhaust clack of medical endoscope trocar sheath.It can solve the slit that exists between scope shank and the trocar sheath and problem that gas is directly discharged from trocar sheath effectively, so that improve quality of medical care.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows: a kind of medical endoscope trocar sheath is prevented exhaust clack, its construction features is, it is a gas can tightly be sleeved on endoscope's trocar sheath and can prevent the scope inflation time rubber finger sleeve that discharges of the slit between sleeve pipe and the scope shank outside, one end of this rubber finger sleeve be can with the belled circular open of scope trocar sheath, it is conical that other end rear portion is, and is the insertable connection opening of scope at conical top.
According to above-mentioned technical scheme: described circular open is loose tight loop configuration; The opening form of described connection opening is cross, rice font or circular apertures, ellipse hole.
Because this utility model can be sleeved on endoscope's trocar sheath in medical treatment easily, make the scope shank enter the anti-exhaust clack of setting up a gas on the end face of trocar sheath behind the trocar sheath, thereby after scope enters human body when inflation gas can not discharge from trocar sheath, can effectively accumulate the position that needs pneumatosis, the scope downward view is exposed fully, promptly reach easy to operate, accurate.Ensure medical condition, improved quality of medical care greatly.
Description of drawings
Below in conjunction with accompanying drawing and concrete embodiment this utility model is further described.
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is scope insertion end hatch frame figure of the present utility model;
Fig. 3 is that this utility model connects scope trocar sheath end opening structure chart.
The specific embodiment
Referring to Fig. 1～Fig. 3, this utility model is a gas can tightly be sleeved on endoscope's trocar sheath and can prevent the scope inflation time rubber finger sleeve 2 that discharges of the slit between sleeve pipe and the scope shank outside, one end of rubber finger sleeve 2 be can with the belled circular open 1 of scope trocar sheath, it is conical that other end rear portion is, and offers the connection opening 3 that scope is inserted at conical top.This circular open 1 is loose tight loop configuration.The opening form of this connection opening 3 is cross.In the medical treatment, circular open 1 of the present utility model directly can be sleeved on the end face of scope trocar sheath outside.Then scope is directly inserted the scope trocar sheath from connection opening 3 and enter human body, inflation, the organ of expansion check point.And the effect that this utility model plays is to prevent that gas from discharging from the slit between scope shank and the trocar sheath.
According to the above embodiments, if change the opening form of connection opening 3 into meter font or circular apertures, ellipse hole, suchlike form all belongs to protection domain of the present utility model.
