In the duct spreader for endoscopic surgery, the membrane sleeve is hermetically connected with the connecting pipe.

In the duct spreader for endoscopic surgery, the mouth gag is provided with a clamping device which is used for limiting the movement of the stretching component.

In the above-mentioned canal spreader for endoscopic surgery, the clamping device comprises a lock and a slot which are matched with each other, and the lock can lock the stretching component when being locked in the slot.

Compared with the prior art, the utility model has the advantages of reducing the damage of the endoscope to the human body, etc.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1, a membrane sleeve; 2. an elastic member; 3. a tension member; 4. a mouth gag; 5. a connecting pipe; 6. a clamping device; 7. locking; 8. a clamping groove.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the duct spreader for endoscopic surgery comprises a membrane sleeve 1 and an elastic component 2 which are connected with each other, wherein the membrane sleeve 1 is used for spreading a duct, the elastic component 2 extends towards a direction away from the head end of an endoscope to form a stretching component 3, the stretching component 3 is used for controlling the stretching and retracting of the elastic component 2, the elastic component 2 is used for driving the stretching and retracting of the membrane sleeve 1, when the elastic component 2 contracts, the membrane sleeve 1 is tightly attached to the outer wall of the endoscope, and when the elastic component 2 is released, the membrane sleeve 1 is spread and forms a channel.

In more detail, the film sleeve 1 has two layers, and the elastic component 2 is arranged between the two layers of film sleeves 1. The elastic component 2 can be arranged to effectively drive the membrane sleeve 1 to move when being folded and unfolded.

More specifically, the elastic member 2 has a spiral shape. When the membrane sleeve 1 is sleeved outside the endoscope, the elastic component 2 spirally surrounds the outside of the endoscope, so that when the elastic component 2 is tightened, the membrane sleeve 1 is tightly attached to the endoscope, and when the endoscope extends into a human body, the membrane sleeve 1 can smoothly enter.

More specifically, the end of the elastic member 2 is fixed to the film cover 1.

In order to make the structure of the elastic member 2 more robust, the elastic member 2 is made of steel wire.

In more detail, the membrane sleeve 1 is connected with an opener 4, the opener 4 is provided with a hollow connecting pipe 5, and the membrane sleeve 1 is sleeved on the connecting pipe 5. After the endoscope is plugged in, the patient can clench the connecting pipe 5 by teeth, so that the mouth gag 4 is held in the mouth of the patient, and the opening and closing of the mouth of the patient are prevented from interfering with examination or operation.

In more detail, the membrane sleeve 1 is hermetically connected with the connecting pipe 5. Because the endoscope is when inserting patient's esophagus, the patient is easy to nausea, vomit, and after sealing connection between membrane cover 1 and connecting pipe 5, the vomitus can be through outside the membrane cover 1 direct follow connector gap discharge body, and can not block up the air flue, prevents that the patient from suffocating, also can not get into patient's oral cavity, has reduced patient's misery, has promoted patient's treatment and has experienced.

In a further elaboration, be provided with chucking device 6 on the mouth gag 4, chucking device 6 is used for restricting the removal of tensile member 3, and chucking device 6 includes kayser 7 and draw-in groove 8 of mutually supporting, can be with tensile member 3 locking when kayser 7 card is gone into the groove. This setting makes things convenient for medical personnel to lock tensile part 3, prevents that membrane cover 1 from strutting at the insertion in-process.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.

Although the terms of the film sleeve 1, the elastic element 2, the tension element 3, the mouth gag 4, the connecting tube 5, the clamping means 6, the latch 7, the catch 8 etc. are used more often, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
