CN2316928Y - Bent orthopedic wire guide device - Google Patents

Abstract

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

Description

Musical form orthopaedics steel wire introducer

This utility model belongs to medicine technology field, is a kind of musical form 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, when walking around circular-arc trouble bone, needs tractive steel wire then uses the bending mosquito forceps, because mosquito forceps is thicker, and steel wire smoother again, thereby steel wire slippage repeatedly often takes place, 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 musical form 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 musical form orthopaedics steel wire introducer, form by a thin and long shank (1) and the handle (2) that is contained in shank (1) one end, the other end that it is characterized in that shank (1) is crooked, and horizontally on this end is 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,, smooth and easy especially, convenient when the skeleton tractive steel wire of edge bending because its needle section is crooked.

2, 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.

3, shank is thin, and is little to the damage of patient's wound surface.

4, simple in structure, be easy to make.

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, one end is straight, the other end bends to the metallic rod of circular arc, 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 curved end needle section of shank (1) has laterally been bored an aperture (A), it is similar to the through wires hole of civilian sewing threads, effect is to penetrate steel wire, because it is soft that steel wire does not resemble when crooked the sewing-needle, 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.Because it is its syringe needle partly is crooked, when the skeleton tractive steel wire of edge bending, smooth and easy especially, convenient.

Claims (3)

1, a kind of musical form orthopaedics steel wire introducer is made up of a thin and long shank (1) and the handle (2) that is contained in shank (1) one end, it is characterized in that the other end of shank (1) is crooked, and horizontally on this end is 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.
