Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a dacryocystorhinostomy is with cotton pusher of hemostasis.
Background
Dacryocystorhinostomy is also known as dacryocystorhinostomy. Dacryocystitis is a common ophthalmic disease and dacryocystitis is a common method for treating this disease. At present, the common operation mode is that under the direct vision of an intranasal endoscope, the lacrimal sac is exposed through the nasal cavity, after the lower end of the lacrimal sac is cut, the mucous membrane of the cavity of the lacrimal sac is directly inosculated with the mucous membrane of the nasal cavity, so that secretion and tear can directly enter the nasal cavity from the lacrimal sac, thereby eliminating the suppurative focus caused by the blockage of the lacrimal sac and relieving the lacrimal effusion phenomenon.
In the dacryocystorhinostomy, hemostatic cotton is required to be filled into the stoma, after the hemostatic cotton is absorbed and degraded, the mucous membrane of the dacryocystorhinostomy and the mucous membrane of the outer side wall of the nasal cavity are continued to form an effective drainage channel of the dacryocystorhinostomy, and therefore dacryocystitis is cured. The documents of the application of the gelatin sponge in dacryocystorhinostomy in the period of No. 027 and No. 012 in the journal of China eye trauma occupational ophthalmology 2005, and the application of the amnion gelatin sponge in the dacryocystorhinostomy in the period of No. 003 and No. 002 in the journal of China eye ear, nose and throat department 2003 are all recorded.
At present, the shaped hemostatic cotton is clamped by a gun-shaped forceps and is directly put into a dacryocystorhinostomy. There are several problems with this approach: 1, the operation in the narrow nasal cavity space is inconvenient; 2, as the hemostatic cotton needs to be larger than the stoma, otherwise the hemostatic cotton is easy to fall off, when the hemostatic cotton is put into the stoma, the everted mucosa at the stoma is easy to be rolled into the lachrymal sac cavity or damaged to cause adhesion, so that the stoma is narrow; 3, the operation process is time-consuming, the operation cavity needs to be fully stopped bleeding, and the lacrimal sac is fully exposed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: provides a pusher which can conveniently place hemostatic cotton in a dacryocystorhinostomy.
The technical scheme adopted for solving the problems is as follows: the hemostatic cotton pusher for dacryocystorhinostomy comprises a catheter and a push rod: the catheter comprises a catheter main body and a conical sleeve connected to the front end of the catheter main body, wherein the conical sleeve is made of elastic materials, and a notch is formed in the conical sleeve to enable the conical sleeve to be stretched; the push rod includes a push rod body, which is longer than the catheter and is inserted into the catheter.
Further, the method comprises the following steps: the front end of the catheter main body is bent, the bending angle is a, a is 10-30 degrees, and the push rod main body can be bent.
Further, the method comprises the following steps: the push rod main body is provided with a positioning flange; when the positioning flange is attached to the rear end of the catheter main body, the front end of the push rod main body just exposes out of the conical sleeve.
Further, the method comprises the following steps: the push rod comprises a handle which is connected with the rear end of the push rod main body.
The utility model has the advantages that: when the utility model is used, the push rod is pulled out, and the hemostatic cotton is put into the catheter from the rear end of the catheter; then the push rod is inserted into the catheter and the hemostatic cotton is pushed forward; then the catheter is put into the nasal cavity, so that the tip of the conical sleeve enters the stoma; then, the push rod is pushed forward continuously, and the hemostatic cotton props up the conical sleeve to enter the stoma; then the catheter is drawn out. Therefore, the utility model can realize that the hemostatic cotton can be put into the dacryocystorhinostomy quickly and effectively. After the hemostatic cotton is compressed by the catheter, the pusher pushes the hemostatic cotton to the front of the conical sleeve, the closed conical sleeve is firstly placed into the stoma at the moment, and then the hemostatic cotton is pushed into the stoma, so that the outward-turned mucosa at the stoma is prevented from being drawn into the lachrymal sac cavity or damaged by the hemostatic cotton. The utility model discloses pusher has and uses safe and reliable, and the operation is convenient, improves the operation effect, obviously shortens the effect of operation time.
Drawings
FIG. 1 is a view of a hemostatic cotton pusher for dacryocystorhinostomy;
FIG. 2 is a view showing the state of the hemostatic cotton pusher for dacryocystorhinostomy pushed out;
labeled as: the catheter comprises a catheter 1, a catheter main body 11, a conical sleeve 12, a notch 121, a push rod 2, a push rod main body 21, a positioning flange 22, a handle 23 and hemostatic cotton 3.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the hemostatic cotton pusher for dacryocystorhinostomy comprises a catheter 1 and a push rod 2, wherein the catheter 1 comprises a catheter main body 11 and a conical sleeve 12 connected to the front end of the catheter main body 11, the conical sleeve 12 is made of an elastic material, a cut 121 is formed in the conical sleeve 12 to enable the conical sleeve 12 to be stretched, the push rod 2 comprises a push rod main body 21, the push rod main body 21 is longer than the catheter 1, and the push rod main body 21 is inserted into the catheter 1.
The catheter main body 11 and the push rod 2 can be made of plastic, the conical sleeve 12 can be made of silica gel, the notches 121 are arranged along the generatrix direction of the conical sleeve 12, and the number of the notches 121 can be three or four.
When the utility model is used, the push rod 2 is drawn out, and the hemostatic cotton 3 is put into the catheter 1 from the rear end of the catheter 1; then the push rod 2 is inserted into the catheter 1 and the hemostatic cotton 3 is pushed forward properly; then the catheter 1 is inserted into the nasal cavity and the tip of the conical sleeve 12 enters the stoma; then, the push rod 2 is pushed forward continuously, and the hemostatic cotton 3 stretches the conical sleeve 12 to enter the stoma; and then withdrawing the catheter 1. The hemostatic cotton 3 is compressed by the catheter 1; and the conical sleeve 12 can firstly enter the stoma and then guide the hemostatic cotton 3 to enter the stoma, so that the hemostatic cotton 3 can not roll the everted mucosa at the stoma into or damage the ostomy.
The dacryocystorhinostomy is positioned on the side wall of the nasal cavity, and the tip of the conical sleeve 12 can enter the ostomy by adjusting the angle of the catheter 1. For convenience, the distal end of the catheter main body 11 is preferably bent at an angle a of 10 to 30 degrees, and the pusher main body 21 is preferably bent. This further facilitates the orientation of the sleeve 12 towards and into the stoma. The reason why the pusher body 21 is bendable is to allow the pusher body 21 to accommodate the bending of the catheter 1, and in this case, the pusher body 21 should be made of plastic having elasticity so as to be elastically bendable.
If the length of the push rod 2 extending out of the catheter 1 is not controlled, the situation that the push rod 2 extends out of the catheter 1 too much when pushing out the hemostatic cotton 3 easily occurs, and the lacrimal sac is pressed too much is easily caused. Therefore, the push rod main body 21 of the utility model is preferably provided with a positioning flange 22; when the positioning flange 22 is attached to the rear end of the catheter main body 11, the front end of the push rod main body 21 just exposes the tapered sleeve 12. The front end of the push rod main body 21 just exposes out of the conical sleeve 12, and the hemostatic cotton 3 is pushed out at the moment; the positioning flange 22 is attached to the rear end of the catheter main body 11, so that the push rod 2 can be prevented from further moving forward, and the utility model is safer to use.
To facilitate the operation of the putter 2, it is preferable that the putter 2 includes a handle 23, and the handle 23 is attached to the rear end of the putter body 21.
In order to avoid causing iatrogenic infection, the utility model is disposable.
