Abstract
The utility model discloses a medical front hole needle. The utility model is characterized in that the front end of a needle body is provided with a thread exit hole; the needle body can be convenient for a suture thread to pass through for sliding, have two open ends, and form a tubular shape, or the needle body can be provided with a concave groove in the axial direction of the needle body. The utility model has the advantages of convenient operation, fast suture speed, fluent suture, no easy looseness and break for suture threads, one-time threading for multiple times of suture, operation time saving, simple structure, and easy manufacture, being the ideal medical suture needle.
Description
This utility model relates to a kind of medical surgical operating theater instruments, particularly a kind of medical preceding vent needle.
It is the sewing needle of selecting band back pin hole for use that traditional surgical operation is sewed up, and parallel through mode is dialled the pin sewing, be about to sew up needle body and pass and need the tissue sewed up, the line hole by the needle body rear portion will be through in advance stitching tape in the line hole cross tissue and break, ligation.Every stitching one pin of this sewing, operative doctor need to pass instrument nurse once with stitchings with utensil, are put on by the nurse and give operative doctor again behind the needlework and carry out the stitching of second pin.This is complex operation not only, and the operation in the considerable time be used for nurse's threading, if nurse's threading speed is slow, often prolong more operating time, increase misery to patient.In order to overcome the problems referred to above, people have carried out a large amount of research work in this respect in recent years, as the disclosed easy to thread operation needle of Chinese patent 209309u, employing offers a gap in the side, line hole at sewing needle rear portion, in order to the line of threading, to guarantee threading speed and to reduce operating time, but this operation needle still need transmit operating theater instruments back and forth, the disclosed new medical sewing needle of Chinese patent 2055366u and for example, it sets up a needle point hole (being wire hole) in traditional position, medical suture needle tip, in order to simplify procedures.But this sewing needle easily increases resistance and tissue injury because suture exposes outside the needle body fully during stitching, needle holder often will be sandwiched on the stitching thread simultaneously, makes the stitching thread fracture of easily loosening, and gives operation increase difficulty.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of easy and simple to handle, and stitching speed is fast, and the outlet smoothness, and vent needle before clamping operation medical is convenient in the stitching thread fracture that is difficult for loosening.
The purpose of this utility model realizes by following technical proposals:
With sew up needle body be designed to be convenient to suture by sliding both ends open the tubulose needle body or be axially arranged with the groove needle body along needle body, be provided with wire hole in the needle body front portion.Also the needle body some can be designed to tubular body, another partly is designed to the groove shape.
Be provided with the projection of being convenient to the needle holder clamping at the needle body rear portion, projection is provided with the suture duct.
Accompanying drawing and drawing are described as follows:
Fig. 1 is an end of tubular needle body structure cut-away view of the present utility model;
Fig. 2 is a tube seat shape needle structure cut-away view of the present utility model;
Fig. 3 is the configuration diagram of this utility model band wire box.
In conjunction with the embodiments this utility model is further described with reference to the accompanying drawings below:
Embodiment 1, as shown in Figure 1, needle body 2 is designed to tubulose, and its outward appearance can be arc, also can be straight shape, and the needle body rear portion is provided with entrance hole 1, and the needle body front end is provided with wire hole 3, and it is inboard for good that wire hole is located at needle point, and present embodiment selects for use wire hole to be located at the needle point inboard.
Embodiment 2, as shown in Figure 2 needle body 2 rear design become hollow tubular, and the two ends of hollow pipe are respectively equipped with entrance hole 1 and portal, the anterior solid that is portals, and be provided with a groove 4 along the needle body direction, and fit in order to line body and needle body, be provided with radially wire hole 3 in the needle point inboard.Be provided with a projection 5 of being convenient to clamping at the needle body rear portion, projection is threaded with needle body is capable, also can projection and needle body design is in aggregates, present embodiment is selected the latter for use, projection 5 is provided with a hollow drawing lines, projection be triangle, rectangle, polygon, circular any, be good wherein with rectangle, present embodiment is selected rectangle for use.
Embodiment 3, be provided with a wire hole 3 radially in the needle tip inboard, be provided with a groove 4 along the needle body axis direction in needle body one side, so that stitching thread and needle body are fitted, groove is good to be located at looper body curved back, the groove of present embodiment is located at looper body back, and the needle body rear portion is provided with the projection of being convenient to clamping.
Embodiment 4, as shown in Figure 3, needle body is designed to the arc tubular body, it is entrance hole 1 and wire hole 3 in addition that the tubular body two ends are divided, be provided with a projection of being convenient to clamping at the needle body rear portion, projection and needle body design are in aggregates, projection is a hexagon, the projection middle part is that a hollow drawing lines links to each other with the tube chamber of tubulose needle body, have additional a line box on projection top, the line box comprises the coil axes 6 on " U-shaped " shell and the corresponding wall of its middle inside, coil axes one end and the hinge joint of line box wall, the other end and line box wall breach or groove clamping.The shell outer lower portion is provided with the intermediate plate 7 of two correspondences, and the shell between intermediate plate is provided with outlet duct 8, and the projection of intermediate plate and preceding vent needle is clamping connection mutually, and is by clamper that intermediate plate and projection clamping is tight during use.
During use, operation suture thread is through at wire hole by needle body tube chamber or groove, and with clamper clamping needle body rear portion or projection, give operative doctor, operative doctor can be sewed up, and during stitching the needle body front portion is passed the tissue of need stitching, lift the end of a thread of sewing needle wire hole, syringe needle is withdrawn from an organization and continues to move back line to needs length along former needle track, cut off for ligation, the end of a thread is still stayed the wire hole position for continuing to sew up usefulness.Such threading can be used for repeatedly sewing up.
From above-mentioned situation as can be known, the purpose of this utility model can realize, stitching thread from the tube chamber of needle body or groove by with slide, the loose crack conditions of stitching thread can not appear, hand-manipulating of needle outlet smoothness during stitching, be difficult for enlarging tissue injury, threading can be sewed up for spininess in addition, has reduced loaded down with trivial details that apparatus transmits back and forth, has saved the time, having improved operative speed, is a kind of ideal operation sewing needle.
