Description

Fixing band imbedding device for posterior naris blocking support

Technical Field

The utility model relates to a ENT surgery apparatus field, in particular to a fixing band imbedding device for a posterior naris blocking support.

Background

The blocking of the posterior nares is a critical disease which directly threatens the life of a newborn, the blocking of the posterior nares at two sides causes difficult breathing and oxygen deficiency of the infant, the life safety of a child patient can be ensured only by emergently passing through the tracheal cannula, but the child patient cannot always carry the tracheal cannula to live, the posterior nares forming operation must be carried out at an early stage, but at present, equipment specially used for supporting the posterior nares is not available, and a surgical instrument specially used for forming the posterior nares is also unavailable.

When the posterior naris is formed clinically, the posterior naris needs to be prevented from being locked again after being opened, so that the support needs to be placed for more than 6 months, the supports used clinically at present are all temporarily manufactured in an operation, the manufacturing process probably needs 1.5 to 2 hours, the operation time is prolonged, the anesthetic dosage of the sick children is increased, the used materials are not uniform, some tracheal cannulas, some three-way tubes and thoracic drainage tubes are used. The tracheal cannula is hard, can press the perforation of the nasal septum, and the nasal alar is deformed, thereby adding extra complications to the sick children; the three-way pipe and the thoracic drainage pipe have thicker pipe wall and thinner pipe cavity, are easy to be blocked by nasal scab, and need to repeatedly clean secretion in the nasal cavity, thereby increasing nursing difficulty, and most importantly, the ventilation is insufficient, and part of the nasal drainage pipe still has breathing difficulty. The three parts have the unified defects of straight shape, no scale mark, no knowing of the placing length, no groove, inconvenient fixation and easy rotation, and the inner end of the breather pipe is blocked by nasopharynx tissues, can not ventilate and can not bend along with the nasal cavity and nasal passage. The U-shaped support is made of the materials and used for ventilation and support, the front end of the U-shaped support penetrates out of the nasal cavity through the front nares on two sides, the rear end of the U-shaped support is propped against the rear end of the nasal septum, once the position is changed, the rear end of the U-shaped tube is easily blocked and cannot ventilate, and general anesthesia operation needs to be performed again. Therefore, the applicant has invented a fixing band implanting device for a posterior naris occlusion support, which includes two ventilation tubes inserted into two nostrils, respectively, so that the fixing band is still required to be used for fixing, and thus a fixing band implanting device is required to be designed.

Disclosure of Invention

The utility model provides a fixing band imbedding device for a back nostril blocking support which is convenient for fixing the support, which overcomes the defects of the prior art.

The utility model discloses a realize through following technical scheme:

the utility model provides a device is put into to fixed band for back nostril shutting support, characterized by includes steel pipe, medical flexible pipe and seal wire, the entering end of steel pipe is the section of bending, medical flexible pipe is longer than the steel pipe to can insert in the steel pipe, seal wire one end is equipped with the buckle that can block the fixed band, the seal wire is longer than medical flexible pipe, and can insert in the medical flexible pipe.

The medical extension tube is 1-2 cm longer than the steel catheter.

And the bending part of the steel guide pipe is in smooth transition.

The guide wire is 2 cm longer than the medical telescopic tube.

The included angle between the bending section of the steel conduit and the main body section is 120 degrees.

The outer end of the steel conduit is in a bell mouth shape.

The utility model has the advantages that:

with the help of the steel catheter, the medical extension tube, the guide wire and the medical long clamp, the fixing band can easily penetrate through the posterior naris, and the two ventilation tubes of the fixing support device can be conveniently inserted. It has simple structure and convenient use, and can be used in an operating room only by local anesthesia.

Drawings

The invention will be further described with reference to the accompanying drawings:

FIG. 1 is a schematic front view of a steel conduit;

fig. 2 is a front view structural schematic diagram of the medical extension tube;

FIG. 3 is a front view of a guidewire;

fig. 4 is a schematic view of a cross-sectional structure of the utility model in the using process.

In the figure, 1 steel catheter, 2 bellmouths, 3 bending sections, 4 medical telescopic pipes, 5 guide wires, 6 buckles and 7 main body sections.

Detailed Description

The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 4, the fixing band implanting device for the posterior naris occlusion support comprises three parts, namely a steel catheter 1, a medical telescopic tube 4 and a guide wire 5, wherein:

the outer end of the steel catheter 1, namely the handheld end, is in a bell mouth shape 2, so that the steel catheter is convenient to hold, the inner end, namely the insertion end is a bending section 3, the bending section 3 is not too long and can not be too long, namely about 0.5 cm, the included angle between the bending section 3 and the main body section 7 of the steel catheter 1 is about 120 degrees, and the bending part is in smooth transition.

The medical extension tube 4 is 1-2 cm longer than the steel catheter 1, and when the medical extension tube 4 is used, the medical extension tube 4 extends out from the bending section 3 by 0.5-1 cm after being inserted from the end of the bell mouth 2.

The inner end of the guide wire 5 is provided with a buckle 6 or a snap ring which can clamp the fixing strap, and the guide wire 5 is about 2 cm longer than the medical extension tube 4.

During operation, a steel catheter 1 is inserted into a nasal cavity on one side, an opening of a bending section 3 faces to a contralateral nasal posterior orifice, a medical telescopic tube 4 is inserted into the steel catheter 1, the medical telescopic tube 4 extends out of the opening of the bending section 3 by about 0.5-1 cm, the outer end of the medical telescopic tube 4 is basically flush with the steel catheter 1, then a fixing band is clamped on a buckle 6, is inserted into the telescopic tube together with a guide wire 5 and extends out of the inner end of the telescopic tube, and crosses the nasal septum posterior end to reach the contralateral nasal posterior orifice; then, a nasal endoscope is placed in the contralateral nostril, the fixing band is clamped by using medical long forceps under the guidance of the nasal endoscope and is pulled out to reach the contralateral anterior nostril, the steel catheter 1 and the medical telescopic tube 4 are pulled out, at the moment, two ends of the fixing band are positioned in the bilateral anterior nostrils, and the middle section is positioned behind the nasal septum; that is, the fixing band passes through the nasal cavity on one side, passes through the rear end of the nasal septum to the nasal cavity on the other side, and then passes out of the nasal cavity on the other side; at the moment, the medical long forceps pass through an air pipe of a support to clamp the fixing band, the medical long forceps are withdrawn to enable the fixing band to pass through the air pipe, the air pipe is enabled to pass through the fixing band, the air pipe is inserted into the nasal cavity on one side, then another air pipe is enabled to pass through the fixing band of the nasal cavity on the other side in the same way, the air pipe is inserted into the nasal cavity on the other side, and then the two ends of the fixing band are tied together.

Other technical features than those described in the specification are known to those skilled in the art.
