Problems solved by technology

[0003] The patent number is 2005201355656.0, and the invention name is "nasal polyp forceps".
At present, there are no special instruments for inferior turbinate fracture surgery, but mucosal dissection instruments are used instead. However, due to the narrow head end of ordinary mucosal dissection instruments, during the operation for inferior turbinate fractures, the local force is too large. It is very easy to cause local mucosal damage, especially if you encounter a hypertrophic patient with obvious bone hyperplasia of the inferior turbinate, it is difficult to achieve the outward movement effect

Abstract

The invention discloses an inferior turbinate fracture outward moving device. A left connecting ring which is processed with a connecting hole is provided with a left forceps head and a left forceps handle; a right connecting ring which is provided with a connecting hole is provided with a right forceps head and a right forceps handle; the left forceps head and the left forceps handle are in the same plane or in different planes; the right forceps head and the right forceps handle are in the same plane or in different planes; the left forceps head is of a half U-shaped structure; the right forceps head is of a half U-shaped structure which is symmetric the left forceps head; protective sleeves are sleeved outside the left forceps head and the right forceps head; the left connecting ring and the right connecting ring are hinged by using a connecting shaft; and a spring piece is arranged between the left forceps handle and the right forceps head. The forceps heads of the inferior turbinate fracture outward moving device are processed into a rectangular structure to enlarge a contact area during an operation; the protective sleeves are sleeved outside the forceps heads to protect mucosa of the inferior turbinate; and when the forceps heads move towards each other, the inferior turbinate fractures at two sides can be moved outwards. The inferior turbinate fracture outward moving device, disclosed by the invention, has the advantages of shorting operation time and being good in fracture outward movement effects, and can be used for operational machinery special for inferior turbinate fracture outward moving operations.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for surgical operations, and in particular relates to clamping instruments for nasal operations. Background technique [0002] With the research on the structure and function of the nasal cavity and the long-term follow-up study of patients with partial inferior turbinate resection, patients with partial inferior turbinate resection will have symptoms such as nasal dryness, empty nose, and open nasal sound in the long run , which brought great pain to the patient, therefore, the external displacement of inferior turbinate fractures has become the main surgical method for the treatment of hyperplasia and hypertrophy of the inferior turbinate. The function of the mucous membrane of the inferior turbinate is well protected. [0003] The patent number is 2005201355656.0, and the invention name is "nasal polyp forceps". The main structure is the same as that of surgical scissors for surger...
