Abstract
The invention discloses a costicartilage cutting device, which comprises a knife handle and a knife head. The invention is characterized in that: the knife handle is connected with the knife head; the knife handle is in a crank; the knife head is in a tubular shape; a groove opening is arranged in the middle of the knife head; a gap is arranged at the front end of the knife head; an arc-shaped protection plate is arranged at the upper end of the gap; and an arc-shaped knife edge is arranged at the lower end of the gap. The costicartilage cutting device is simple in structure, safe, reliable, convenient to operate and flexible, and the outside costicartilage can be cut, so that operative procedures are simplified, the operation difficulty is lowered and the economical burden of patients is reduced.
Description
Technical field
The present invention relates to the medical device technical field, specifically a kind of costicartilage cutting device.
Background technology
Costal cartilage grafting is by wide clinical application.Carry out costal cartilage grafting at present, normally costicartilage is cut off, and its monoblock is taken out, and then repair according to the needs of transplantation site with scalpel.Adopt scalpel carry out problem that costicartilage cuts existence be difficult for precisely control, operating time is long, wound is big, and causes pneumothorax to take place easily.Especially when the deformity of nose that harelip is caused is repaired, because required costicartilage shape is little, it is bigger therefore to carry out operation easier with scalpel, has also increased unnecessary risk simultaneously.
Summary of the invention
The object of the invention just provides costicartilage cutting device a kind of simple in structure, safe and reliable, easy to operate.
The objective of the invention is to realize like this:
Costicartilage cutting device provided by the present invention includes handle of a knife and cutter head; Its key points in design is that described handle of a knife, cutter head are connected as a single entity, and its handle of a knife is crank, and cutter head in a tubular form; The middle part of cutter head has notch; The front end of cutter head is provided with breach, and the upper end of breach is the arc backplate, and the lower end of breach is a curved blade.
The design of its cutter head arc backplate of the present invention and curved blade can make the doctor when cutting costicartilage, can accurately control the thickness and the width of the costicartilage of getting, and the costicartilage that is downcut also can be stored in the tube seat of cutter head at once, and can from notch, take out easily.This shows that the present invention is simple in structure, safe and reliable, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the left view of Fig. 1 cutter head portion.
The specific embodiment
The present invention is as shown in Figure 1, includes handle of a knife 1 and cutter head 2, and wherein, handle of a knife 1, cutter head 2 are connected as a single entity; Its handle of a knife 1 is crank, cutter head 2 in a tubular form, the middle part of cutter head 2 has notch 3; The front end of cutter head 2 is provided with breach, and the upper end of breach is an arc backplate 4, and the lower end of breach is a curved blade 5.
Cutter head 2 among the present invention can process with the medical stainless steel pipe.Cutter head 2 front ends are clipped the part tube wall as required and are formed breach, and curved blade 5 is processed in the breach lower end, are used to get costicartilage; Form arc backplate 4 after the Passivation Treatment of breach upper end, this backplate can prevent to get the excessive and accidental amputation rib of bone angle.Clip the part tube wall as required at cutter head 2 mid portions and form notch 3, bone storing groove 6 of this notch 3 and the common formation of the tube chamber in the cutter head 2 is used to store the costicartilage of intercepting.
The camber H of the curved blade 5 among the present invention, chord length L all can set according to clinical needs.Camber H wherein is used to limit the thickness that cuts costicartilage, and chord length L is used to limit the width that cuts costicartilage.Generally camber H should be less than the whole thickness (about 10mm) of normal costicartilage, and chord length L should be less than the width (about 10mm) of costicartilage.
In order to improve versatility of the present invention, the camber H of curved blade 5 is preferably designed as 1-4mm among the present invention, and chord length L is preferably designed as 2-6mm.Its more preferred scheme is, the camber H of curved blade 5 is 2-3mm, and chord length L is 4-5mm, so is more suitable for cutting chapped lip patient deformity of nose and repairs required costicartilage.
Handle of a knife 1 among the present invention can be designed as the shape of similar blade holder, but preferably is tubular.So both be convenient to whole the manufacturing, and also be convenient to the operator and hold.
The present invention does a kerf preparing to get on the thoracic wall of costicartilage in use, cuts skin, subcutaneous tissue and muscular tissue, exposes costicartilage.One of operator holds the handle of a knife 5 of tight costicartilage cutting device; The another hands is arc backplate 4 fixedly, then curved blade 5 is placed directly over the costicartilage that will get, makes curved blade 5 incision costicartilages downwards with suitable dynamics; And firmly cut costicartilage along the rib direction, until required length.Withdraw from slightly backward then, block the part costicartilage that has cut with scalpel, block back costicartilage bone piece and be stored to (being in the bone storing groove 6) in the tube chamber in the cutter head 2, the operator can take out the costicartilage that cuts from notch 3.
The present invention can effectively avoid the improper and generation of complication such as the pneumothorax that causes, nerve injury of operation technique.Therefore the present invention not only can reduce operation risk greatly; Simultaneously also can reduce operating difficulty, alleviate patient economy burden.
