Abstract

The utility model discloses a four-claw rib bone fracture plate of the field of medical instruments. The four-claw rib bone fracture plate comprises a plate body and fixing claws. The plate body is rectangular, a pair of the fixing claws is arranged on each of two ends of the plate body, and each pair of the fixing claws is bent oppositely and forms a semi-oval shape with the plate body. The upper sections of the fixing claws are narrowed from the plate body to the bent positions, the outer sides of the fixing claws are oblique lines, and the inner sides of the fixing claws are arc lines. The lower sections of the fixing claws are rectangular from the bent positions to the end portions close to the fixing claws, and the end portions of the fixing claws are semi-round. The plate body and the fixing claws are made of pure titanium materials. The four-claw rib bone fracture plate has the advantages that operation is convenient and fast, and fixing effect is good; range between superior margin intercostal muscles and inferior margin intercostal muscles on two sides of a dissociated lacerated end in the process of implanting the bone fracture plate is small; incision of a patient is small so that damage of chest wall muscles is small; the bone fracture plate can be implanted easily due to angle relations under the condition of special portions (such as second rib and root rob fracture); and the bone fracture plate can be taken out easily after fracture healing.

Description

The four paws rib connecting plate

Technical field

This utility model relates to a kind of medical apparatus and instruments, and more particularly, this utility model relates to a kind of a kind of four paws rib connecting plate that is used for the treatment of the fracture of rib patient.

Background technology

Because contingency causes the patient of fracture of common occurrence, fracture is brought very big inconvenience and physiology and the spiritual very big misery, particularly fracture of rib of live and work to the patient, and is adjacent with people's vitals because being positioned at thoracic wall, to people's injury more very.For this reason, research is made the medical apparatus and instruments for the treatment of fracture of rib and is constantly updated development, and eight pawls that generally use at present or the above blade plate of eight pawls are the main apparatuses for the treatment of fracture of rib, and effect is better.But just there is following defective in this blade plate because length is long: the one, and on the broken ends of fractured bone both sides of dissociating when implanting blade plate, the scope of lower edge Intercostal muscle is larger; The 2nd, cause patient's otch large, thereby the thoracic wall muscle injury is also just large; The 3rd, meet privileged sites (the 2nd rib, root fracture of rib), due to angular relationship, be not easy to implant; The 3rd, after union of fracture, blade plate takes out and is not easy.In view of this, need to improve the defective of above-mentioned prior art, the rib connecting plate that a kind of therapeutic effect is good, reduce the patient suffering is provided.

Summary of the invention

The purpose of the present utility model is to overcome the deficiencies in the prior art, and the four paws rib connecting plate that a kind of therapeutic effect is good, reduce the patient suffering is provided.

The purpose of the present utility model is achieved through the following technical solutions:

A kind of four paws rib connecting plate comprises plate body and fixed claw.The plane of described plate body is rectangle, and its two ends respectively are provided with a pair of fixed claw, the every pair of fixed claw all in opposite directions bending become half elliptic with plate body.The epimere of described fixed claw from plate body to bending part by wide to narrow, its outside be oblique line, the inboard is camber line; The end of the hypomere of described fixed claw from bending part to nearly fixed claw is rectangle, and its end is semicircle.Described plate body and fixed claw adopt pure titanium material to make.The length of described plate body is 20 to 40 millimeters, and width is 8 to 12 millimeters; The length of described fixed claw is 15 to 20 millimeters, and width is 2 to 3 millimeters; The thickness of described plate body and fixed claw is 0.8 to 1 millimeter.

Compared with prior art, the utlity model has following beneficial effect:

1. length significantly shortens, and the quantity of fixed claw reduces at double, makes operation more convenient, good fixing effect;

2. when implanting blade plate on the free broken ends of fractured bone both sides scope of lower edge Intercostal muscle less;

3. patient's otch is little, thereby the thoracic wall muscle injury is also just little;

4. meet privileged sites (the 2nd rib, root fracture of rib), due to angular relationship, more easily implant;

5. after union of fracture, blade plate is easier to take out.

In figure: plate body 1, fixed claw 2, knochenbruch 3.

The specific embodiment

The below is described in further detail this utility model essentiality content just in conjunction with the accompanying drawings and embodiments:

As Fig. 1-1 to as shown in Fig. 2-2: a kind of four paws rib connecting plate comprises plate body 1 and fixed claw 2 two parts.Plate body 1 plane is rectangle, and its two ends respectively are provided with a pair of fixed claw 2, and the every pair of fixed claw 2 is 1 one-tenth half elliptic of bending and plate body in opposite directions all.The epimere of fixed claw 2 from plate body 1 to bending part by wide to narrow, its outside be oblique line, the inboard is camber line; The end of the hypomere of fixed claw 2 from bending part to nearly fixed claw 2 is rectangle, and its end is semicircle.Whole blade plate picture half anchor ear shape.Plate body 1 and fixed claw 2 adopt pure titanium material to make.The length of plate body 1 is 20 to 40 millimeters, and width is 8 to 12 millimeters; The length of fixed claw 2 is 15 to 20 millimeters, and width is 2 to 3 millimeters; The thickness of plate body 1 and fixed claw 2 is 0.8 to 1 millimeter.

Embodiment: as shown in Figure 3; free fracture two ends; cut lower edge Intercostal muscle on rib; protection intercostal nerves and blood vessel reset knochenbruch 3, insert the four paws rib connecting plate; synthetism is tabular as half anchor ear; clamp four fixed claws 2 with forceps, make it to be fixed on the two ends of knochenbruch 3, between blade plate and knochenbruch, CONTACT WITH FRICTION is arranged.The four paws rib fixing plate adopts pure titanium material to make, and the existing rigidity of pure titanium material is flexible again, can be converted into the curvature that adapts with knochenbruch 3, attaches the gabarit of knochenbruch 3, reaches the effect of fine fixation of bone fragments 3.Merge the hydrothorax person, attract hydrops under incision pleura or thoracoscope in art.After the knochenbruch healing, with Medical bottle opener, four fixed claws 2 are pried open, can be taken out blade plate.

Clinical use this utility model on November 23rd, 20 days 1 was implemented fracture of rib internal fixation 93 examples altogether from December in 2011.Male wherein: 78 examples.Women: 15 examples.Age: 20-80 years old.Traffic accident wound 34 examples.Fall down wound 26 examples (falling down by bike 11 examples).High falling wound 17 examples.Weight injures 8 examples by a crashing object.Other hinders 8 examples.Right side 44 examples, left side 42 examples, bilateral 7 examples.Closed drainage of pleural cavity 72 examples.

Surgery situation (meansigma methods, lower with): patient age (year) 53.9 ± 12.7, the number (individual) 5.9 ± 2.2 of fracturing, fixed number (individual) 3.9 ± 1.8, opportunity of operation (my god) 6.1 ± 3.2, the hospital stays (my god) 13.6 ± 6.1.

Postoperative outcome: pain is obviously slowed down; Thorax recovers normal morphology, improves respiratory function; Complication: the pneumonia incidence rate reduces; The postoperative CT examination: the rib three-dimensional reconstruction shows fracture fixation place good apposition.
