Description

Pincer-shaped suture type nasal septum anastomat

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a pincer-shaped suture type nasal septum anastomat.

Background

Nasal septum deflection is one of the more common diseases of otolaryngological department, and nasal septum deflection is a common disease and frequently encountered disease of the department of rhinolaryngology. The incidence of disease is reported to be 51% in the population, with symptoms requiring treatment being 12%, i.e., approximately 6 individuals per hundred of the population are in need of treatment. Nasal septum deflection is related to factors such as congenital development and trauma, and patients with severe deflection degree can cause nasal cavity ventilation and nasal sinus drainage disorder, and symptoms such as nasal obstruction, nasal bleeding and reflex headache appear, and long-time adverse symptoms can seriously affect the life quality of patients and even affect the psychology.

Nasal septum orthopedics treatment nasal septum deflection uses extensively in clinical treatment, and the postoperation is in order to fix the nasal septum and effectively stanch, and the current common mode at home and abroad is nasal cavity tamponade method. Headache, nasal obstruction, dry mouth, dysphagia and other complications of patients can occur during the filling period, and complications such as nasal cavity and paranasal sinus infection, tympanometer effusion and the like are easy to occur, nasal reflex is induced seriously and even, and serious complications such as arrhythmia, myocardial infarction and the like occur; the operation of taking out the nasal cavity stuffer causes more pain to most patients, fear and conflict psychology to treatment are generated, secondary bleeding can be caused, and syncope shock can be caused by serious patients.

Preliminary research results in the early stage show that the nasal septum suture can not only effectively fix the nasal septum cartilage and repair the torn mucous membrane, but also effectively avoid the pain of the patient caused by the extraction of the packing. In the aspect of postoperative recovery, the nasal cavity of a patient subjected to nasal septum suture is relatively clean, secretion in the nasal cavity needs to be treated less after operation, and postoperative recovery is relatively quick; the nasal septum suture can sew the incision and knot at the skin of the nasal vestibule, which is beneficial to the healing of the incision and has good alignment and beautiful appearance. The nasal septum suture can obviously improve the discomfort symptom of a patient after operation, protect the function of the nasal mucosa to a greater extent, reduce the occurrence of postoperative complications, lead the patient to recover quickly and lead the nasal septum to be corrected satisfactorily. In short, the nasal septum suture belongs to a novel technique, and requires an operator to have a skilled nasal cavity operation technique. Compared with the nasal cavity tamponade method, the nasal septum suture method can obviously reduce the pain and the economic burden of the patient, help the patient to recover as soon as possible, has low incidence of postoperative complications and shortens the hospitalization time, so the nasal septum suture method is worthy of clinical popularization and application. However, due to the narrow nasal cavity, no special instrument suitable for nasal septum suture is available, and compared with the traditional stuffing method, the method has the defects of inconvenient operation and prolonged operation time. For beginners, the difficulty of learning is increased, and many young doctors do not like to learn and try, so that the popularization and application of the nasal septum suture are hindered. Therefore, it is necessary to find a nasal septum anastomat suitable for nasal septum suture to solve the disadvantages of inconvenient operation and prolonged operation time of nasal septum suture.

As shown in FIG. 7, the driving rack 25 drives the first frame 11 fixedly connected to the driving rack 25 to move, and further drives the suture needle 112 at the distal end of the first frame 11 to approach the opening of the independent supporting cavity 121 at the distal end of the second frame 12, which is opposite to the surface of the first frame 11. The transmission rack 25 drives the first support 11 to move and simultaneously drives the swing rack 13 to move, when the swing rack 13 reaches a specified position, the swing rack is meshed with the swing gear 123 to drive the swing gear 124 to rotate, the swing gear 124 drives the swing shaft 122 to perform reciprocating circular rotation in the shaft hole 123, and then the swing needle 125 at the tail end of the swing shaft 122 is driven to perform reciprocating rotation. The above steps can realize the matching of the swing needle 125 and the suture needle 112, and after the suture needle 112 drives the suture thread 90 to pass through the suture tissue, the swing needle 125 can hook the suture thread 90 by using the hook end thereof.

After the suture of the needle swing 125 is completed, the operator pushes the retraction driving plate 1161 on the first frame 11 out of the nasal cavity to drive the retraction base plate 1162 to slide proximally in the outer sliding slot 114, so that the suture needle 112 rotates back into the inner sliding slot 115 of the first frame 11. Then the operator applies force to the outside of the nasal cavity by hand to push the finger pressing pushing block 322 of the positioning pushing mechanism 30 to slide towards the near end in the upper sliding chute 311, the nostril fixing bracket 33 is retracted, and the suturing mechanism 10 is withdrawn from the nasal cavity, thus completing the suturing of the clamp-shaped suturing type nasal septum anastomat to the suturing tissue.

The clamp-shaped suture type nasal septum anastomat is provided with the control mechanism 20, an operator can hold the control mechanism 20 with one hand to operate, then the suture mechanism 10 is controlled to suture tissues, and the control mechanism 20 is further provided with the return spring 28, so that the operation difficulty and fatigue of the operator can be reduced. The clamp-shaped suture type nasal septum anastomat can adapt to different nasal cavity environments by designing the distributed pushing and positioning mechanism 30, the application range of the clamp-shaped suture type nasal septum anastomat is expanded, the precise movement of the clamp-shaped suture type nasal septum anastomat in a nasal cavity can be realized, and the suture precision of suture tissues is improved. Suture tensioning mechanism 40 ensures that suture 90 can only be wound out in one direction and provides suture 90 with some tension during operation. The suturing mechanism 10 is configured to deploy and deploy, puncture, and suture the suture needle 112 within the nasal cavity. The design of above structure has solved the inconvenient problem of operation that exists in the traditional approach and then has shortened operation time, has reduced the technical difficulty of current septum nasi suture art.

While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the invention is to be defined by the scope of the appended claims.
