Description

Wicresoft's memory alloy rib blade plate

Technical field

This utility model belongs to medical apparatus and instruments, relates to a kind of internal fixtion bone-setting device, the Wicresoft's memory alloy rib blade plate be specifically related to.

Background technology

The internal fixation materials such as current utilization draw point, Kirschner wire, steel plate are performed the operation, and surgical injury is large, fixing insufficient, easy rotation, get loose, fixed effect is undesirable, and the pain increased to cause chest deformity to make in various degree, have a strong impact on the respiratory function of patient, need long-term bed; Pain stimulation affects patient's cough, spits, and cause pulmonary infection, obstructive atelectasis etc., severe patient need use mechanical ventilation for a long time.Synthetic resin has Absorbable rod feature, does not need second operation to get fixture, but need insert in medullary cavity when it is fixing, easily occurs infecting, and fixed effect is not firm.When above-mentioned operation technique is fixed, difficulty is comparatively large, and operating time is longer, takes out difficulty after the more important thing is healing, if misoperation also can hurt intrathoracic internal organs.Therefore, these internal fixation methods have certain risk, poor effect.Although the patent No. is 200420086583.6 1 kinds of surrounding oval bone setting plates solve rib fixation problem, but because its architectural characteristic, usually need to cut chest wall cutaneous, muscle etc. when implanting and take out, wound is large, it is attractive in appearance that post-traumatic patient does not usually reach outward appearance thoracic wall, and add the pain etc. of patient.

Utility model content

This utility model object be to provide a kind of rational in infrastructure, safe and reliable, be applicable to fracture of rib internal fixtion Wicresoft's memory alloy rib blade plate, with the Minimally Invasive Surgery that tunnel fracture of rib of moving under water under completing the subcutaneous or muscle of Total thoracoscopy thoracic wall is fixing.

The technical solution adopted in the utility model to achieve these goals: Wicresoft's memory alloy rib blade plate, comprise bending arc blade plate body, blade plate body both ends are respectively epimere, the both sides of each epimere are provided with and encircle arm, often pair of two arms of encircling arm are rolled into open annular structure, have toothed circular hole on epimere and in the middle part of blade plate body.

Preferably, described toothed circular hole has groove near the position encircling arm.

Further, described often pair of two arms of encircling arm have an elongate holes.

Further, described often pair of termination encircling two arms of arm is wedge angle.

Further, the both sides in the middle part of blade plate body arrange curling in opposite directions, and are rolled into open annular structure, and two curling ends are wedge angle.

Further, described arc blade plate decurvation, be provided with below it described encircle arm, curling.

Further, the epimere at described arc blade plate body, blade plate body both ends, the encircling curling that in the middle part of arm and blade plate body, both sides are arranged in opposite directions and make by TiNi material is one-body molded of epimere both sides.

the beneficial effects of the utility model are:

1. in fracture of rib operation, after selecting sizeable this utility model to implant, hot compress bone fracture device, fracture of rib face can be tightly held tightly after deformation recovery, and realize lasting self-pressurization function, more be conducive to the close contact of fracture line, make fixed, integrity and the stability of thorax is recovered rapidly after meeting post-traumatic operation in patients, correct chest deformity, reduce pain, compared with traditional orthopedic instrument, this art formula is simple to operate, safe and reliable, local is a face contact, do not affect blood fortune, can not cut periosteum in art encircles fixing as periosteum, bone healing time can be shortened, and it is little to Peripheral Vascular Injuries, the blood circulation that can remain valid.Easy to use in implant surgery, do not need boring, can intraoperative hemorrhage be reduced, and simplify operation technique, shorten operating time thus alleviate the misery of patient.This utility model art shapes is simple, novel in design, simple, the easily deformable installation of production and processing, in the middle part of the centre of epimere and blade plate body, have a toothed small sircle hole, facilitate implantation and the direction adjustment of bone fracture device, be beneficial to observe and suffer from symphysis situation.

2. the toothed circular hole of this utility model has little groove, be beneficial to position adjustment when bone fracture device is implanted; Each arm has an elongate holes, facilitate the taking-up of bone fracture device; The termination of each arm is wedge angle, is beneficial to and draws encircling arm from the upper and lower edge of fracture rib in thoracic cavity; Both sides in the middle part of blade plate body are provided with curling in opposite directions, and are rolled into open annular structure, and two curling ends are wedge angle, effectively can increase the alignment to the fracture line left and right sides; This utility model blade plate body is designed to different radians according to the situation of different patient, meets various demand, flexible Application.

3. to encircle the termination of arm curved, smooth inward for this utility model, and two to encircle the opening of the open annular structure that arm is formed comparatively large, and be particularly suitable for the internal fixtion of rib, it can effectively prevent from damaging pleura, reduces and stimulates the friction of pleura, reduce the damage to rib undertissue; Postoperative rapid recovery thorax integrity and stability, correct chest deformity, avoid the rib broken ends of fractured bone to damage the continuation of intrathoracic internal organs.In addition thinner thickness, and rib surface fits tightly, to the little blood circulation that can remain valid of Peripheral Vascular Injuries, decrease fracture damage around, energy early ambulation, eases the pain, improves respiratory and circulatory function, reduces the generation of respiratory tract complication.

4. this utility model is made by TiNi material is one-body molded, has temperature memory function, has the material of good biocompatibility simultaneously, in clinical middle extensive use, and safe after implant into body, nontoxic, nothing rejection.
