Description

Nasal septum postoperative anastomat

Technical Field

The invention relates to the field of medical instruments, in particular to a nasal septum postoperative anastomat.

Background

The nasal septum is positioned between the bilateral nasal cavities and consists of an ethmoid vertical plate, a plow bone, nasal septum cartilage and mucous membranes covered on the surfaces of the nasal septum cartilage. The deviation of nasal septum can cause physiological dysfunction of nasal cavity and nasal sinuses and produce symptoms (such as nasal obstruction, headache, epistaxis and the like), and the surgical correction is the only effective treatment method. The specific mode of nasal septum deflection correction surgery is to peel off the two side mucous membranes from the nasal septum bone/cartilage, remove the severely deflected part of bone/cartilage in the cavity formed by the two mucous membranes, or release the tension line causing deflection. An important step is to reattach the mucosa on both sides to eliminate the surgical cavity and promote healing. The most common method currently used to close the operative cavity is compression with bilateral nasal tamponade strips or expanding sponges to prevent hematoma formation in the operative cavity and promote mucosal healing, but with corresponding discomfort to the patient, including pain, tears and nasal infections. Although the prior literature reports that the continuous penetration suture of the mucous membranes at both sides of the nasal septum can achieve the corresponding purpose to avoid nasal cavity filling, the doctor can not be popularized and applied because the operation space of the doctor holding the curved needle at the deep part of the nasal cavity is narrow, the difficulty of the doctor in the upper hand is large, and the suture time is long. Therefore, if the nasal septum anastomosis device which is simple and convenient to operate can be designed, the operation experience of a patient can be obviously improved, the wound healing is promoted, and the operation time can be greatly shortened.

Disclosure of Invention

The object of the present invention is to solve the above problems and to provide an anastomotic device for simplifying the mucosal suturing after nasal septum surgery.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

Further, in the binding structure, the binding portion is a pressing portion to which a binding needle is attached, and the anvil portion is a supporting portion to receive the pressing.

Further, binding department include the casing, press the splenium and be equipped with the spout of binding needle in, the spout in be equipped with the oblique angle slider, press the splenium installation at the casing lower extreme, press the splenium downside to be the spring, the upside top is in the oblique angle slider outside, the binding needle place in the intracavity that holds in oblique angle slider the place ahead.

Furthermore, a staple outlet is arranged at the lower part of the top end of the sliding chute.

Furthermore, a pressing and bearing groove is formed in the position, corresponding to the staple outlet at the lower portion of the top end of the sliding groove, of the chopping board portion.

Preferably, the binding needle is made of a material which can be absorbed by the human body.

Furthermore, the side shape of the anastomat after the nasal septum operation is gun type, namely, a bent angle is formed between the lower handheld handle and the upper anastomosis operation forceps, wherein the anastomosis operation forceps are gun bodies, and the handheld handle is a gun handle.

The invention provides an apparatus capable of performing anastomosis operation in nose, which has the advantages and effects that:

(1) the nasal septum is deflected and is corrected postoperative anastomat connecting axle front end and stretch into both sides nasal cavity respectively through nasal septum, and the both sides mucous membrane that will peel off is direct to coincide through the apparatus, has: safety, rapidness, convenient operation and the like.

(2) The operation not only can quickly inosculate the mucous membrane, but also solves the discomfort caused by long-term nasal cavity stuffing of a patient after the conventional nasal septum deflection correction operation and the difficulty of suture operation of an operator in the deep part of the nasal cavity.

(3) The front end of the instrument for anastomosis is a detachable device, so that the single-line anastomosis and the single-multiple-line anastomosis can be realized, the precise part anastomosis can be realized, and the mucosa anastomosis can be quickly completed.

(4) The material used for anastomosis is made of absorbable material, which reduces the pain of withdrawing nasal plugs and removing sutures in the nose after operation.

(5) The postoperative nasal cavity suture instrument is changed, thereby being convenient for operation, shortening the operation time and reducing the pain of patients.
