Abstract

The utility model relates to an implement for directly importing a steel wire into a bone. The utility model is composed of an operating handle and a long, thin and straight needle rod. The root part of the needle rod is thick, and the head part is thin. The head part of the needle rod is provided with a small hole which leads a steel wire to be penetrated and a small groove embedded into the steel wire. The utility model is used for penetrating and pulling a steel wire in a clinical orthopaedics operation. The usage is convenient and reliable. The steel wire does not easily slip. The efficiency of the operation can be improved. A patient's pain can be lightened. The utility model has the advantages of simple structure and easy fabrication.

Description

Straight formula orthopaedics steel wire introducer

This utility model belongs to medicine technology field, is a kind of straight formula orthopaedics steel wire introducer.

Often need penetrate steel wire in the clinical orthopaedics operation with the fixing bone of suffering from, but be not exclusively used at present and wear the operating theater instruments of drawing steel wire, mosquito forceps commonly used is for it when clinical, because mosquito forceps is thicker, and steel wire is smoother again, thereby steel wire slippage repeatedly often takes place, and surgical wound surface is big, increase hemorrhage, time-consuming bothersome effort.

The purpose of this utility model provides a kind of structure small and exquisite, easy to use and reliable a kind of straight formula orthopaedics steel wire introducer with regard to being to remedy the deficiency of above technology.

This utility model is achieved in that a kind of straight formula orthopaedics steel wire introducer, form by an elongated and straight shank (1) and the handle (2) that is contained in shank (1) one end, it is characterized in that horizontally on the other end of shank (1) being drilled with an aperture (A) that can penetrate steel wire.Damage is reduced to a minimum to wound surface in order to make this introducer, the end face that is drilled with aperture (A) end on shank (1) has sulculus (B), so that wear when drawing steel wire after allowing steel wire pass aperture (A), allow steel wire embed in the sulculus (B) and be unlikely the disturbance wound surface, equally, shank (1) is equipped with the cross section average diameter of handle (2) one ends more than or equal to the cross section average diameter that has aperture A one end, make shank (1) more smooth and easy when penetrating human body, littler to the wound surface damage, to reduce patient's bleeding and misery.

Adopt this utility model will obtain following effect:

1, shank has the aperture (A) that penetrates steel wire, and steel wire probability of slippage in operation process significantly reduces, and can improve the reliability of work, and save time, and has just alleviated doctor's labor intensity, has alleviated patient's misery.

2, shank is thin, and is little to the damage of patient's wound surface, also can alleviate the damage and the misery of patient's wound surface.

3, simple in structure, manufacturing is used all very convenient.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is this utility model shape assumption diagram.

Fig. 2 is a K place longitudinal section partial enlarged drawing among Fig. 1.

As seen from the figure, shank 1 be one elongated, straight metallic rod, its cross section generally is a circle or oblate, its end is fixed with a handle (2), shown in this figure is the normal dicyclo butterfly type handle that adopts in the medical operating, being convenient to the operator goes into to manipulate with two finger insertion rings, the other end needle section of shank (1) has laterally been bored an aperture (A), it is similar to the through wires hole of civilian sewing-needle, effect is to penetrate steel wire, because it is soft that steel wire does not resemble when crooked the sewing threads, so on the syringe needle end face of this end of aperture (A), opened a sulculus (B) again, steel wire is being pierced into, can embed in the process of drawing in the sulculus (B), wear the damage that is pulled through in the journey patient's wound surface to reduce steel wire.

During use,, only need steel wire is penetrated in the aperture (A), shank (1) is thrust human body get final product if pierce into steel wire to human body.If draw in steel wire to human body, just earlier shank (1) is thrust human body and steel wire is penetrated in the aperture (A) again, steel wire is drawn in the human body.Smooth and easy for ease of shank (1) turnover human body, shank (1) is made generally in the needle point place state thinner than crown portion.

Claims (3)

1, a kind of straight formula orthopaedics steel wire introducer is made up of an elongated and straight shank (1) and the handle (2) that is contained in shank (1) one end, it is characterized in that horizontally on the other end of shank (1) being drilled with an aperture (A) that can penetrate steel wire.

2, introducer according to claim 1 is characterized in that being drilled with on the said shank (1) on the end face of an end of aperture A and has a sulculus (B).

3, introducer according to claim 1 is characterized in that said shank (1) is equipped with the cross section average diameter of handle (2) one ends more than or equal to the cross section average diameter that has aperture (A) end.
