Description

Surgical device for ligating and piercing the item the invention forms a surgical device .zum tying and piercing with Thread supply bobbin and guiding the thread on the blunt piercing hook pointing sideways up to the final eye. The purpose of the device is to thread a To make suture superfluous after each ligature, thereby reducing the surgeon's work becomes easier and can be carried out more quickly.

In known devices of this type, the thread "as a result of looping easily grasped at the wrong place @ and pulled out of the eye, which means that a new threading is necessary - and the thread interferes with the operation.

In the case of a device in which the ligation hook is fully open is pierced and the thread is guided through the hole to the end of the hook, In order not to make the threading too shear, the needle must be larger than usual will. These inconveniences are avoided according to the invention in that for guidance of the thread on the piercing hook merging channels, furrows and Eyes are provided, one of which is in the front part of the piercing hook lying covered guide channel, which at the front end into the terminal eye and at the rear end into a groove of the running along the curvature of the hook Piercing hook passes over, pulling the thread out of the: terminal Eye prevents.

In the drawing is a device designed according to the invention for example shown.

They show: Fig. I and z the device seen from two sides, Fig. 3 the device seen from the top, fig. q. and 5 the outer end of the piercing hook in section and rear view on a larger scale, Figure 6 shows another embodiment of the piercing hook in Fig. i seen from above, Fig. 7 a further embodiment of the piercing hook in section on a larger scale.

The device has, in a known manner, a handle a, a shaft b and a piercing hook c, which extends sideways from the upper end of the shaft at a right angle, is semicircular and has a blunt tip and an eye d at its free end. The bobbin f is accommodated in or on the handle a. From the thread spool f, the thread F runs along the shaft b to the piercing hook c. A longitudinal slot i can be provided in order to guide it well despite the easy insertion of the thread.

To guide the thread on the piercing hook c there is an eyelet h at the transition from the shaft b to the hook c. According to the invention, a lateral guide groove Z (Fig. Q and 7) and a longitudinal channel m are provided on the hook c. The canal m (Fig. Q.) Is near the eye d in the piercing hook. On either side of this channel the guide groove extends L. However, the channel m can also extend over a greater length of Durchstechungshakens, as shown, extend, also the groove L. The thread F extends from the eyelet h l through the groove and the channel m. To the eye d. The guide eye k, the guide groove l and the guide channel m can be attached to the rear as well as to the front of the piercing hook c of the device (Fig. 3 and 6).

According to Fig. 7, the cover channel m is formed by a long, strongly sloping one Eye d formed.
