Abstract

The invention relates to a medical technique. The purpose of the invention is to reduce the morbidity and reduce the time of the ligature. The device comprises a handle, a needle 2 and a mandrel 3, which is fixed on the slider 4 of the handle with a screw 5. The working end of the needle is C-shaped curved. At the bottom of the groove of the semi-oval shape there is a hole leading into the lumen of the canal inside the needle. In the mandrel on the needle, between the ram 4 handles and the cannula of the needle 2, a semicircle washer 8 is made. The washer limits the movement of the proximal end of mandrel 3 into the channel of the slider 4 and allows the mandrel 3 to be set so that its pointed edge is facing the hole in the sidewall and prevents its displacement around the axis. 3 il.

Description

Phie. i

The invention relates to medicine, namely to otolaryngological instruments, and can be used for stitching in hard to reach places, for example, in the area of the nasal septum.

The aim of the invention is to reduce the morbidity and reduce the time of the ligature,

FIG. 1 shows schematically a device, a frontal projection; FIG. 2, the same side view; in fig. 3 shows the node I in FIG. 2

The device contains a handle 1, a needle j. Then, when the slider 4 handles 2 and mandrel 3 are moved. The mandrin is located in the needle cavity, and its end is fixed on the slider 4 handles with a screw 5. The working end of the needle 1 is C-shaped. On the implant wall, the needles 1 have -2 ° with a groove 6 of semi-oval shape. At the bottom of the groove 6 there is a hole leading into the lumen of the channel inside the needle. The sharp end of mandrel 3 is sharply angled and pointed with a sharp edge 7 25 to the hole in the wall of the needle 1. In the mandrel in the area located between the slider 4 handles and the cannula of the needle 1, the semicircle of the mandrel 3 is made free of external the edge of the groove 6 and thus releases the thread. The latter is grasped with forceps, and the needle is removed from the wound channel.

Claims (1)

Invention Formula A suturing device, comprising a half C-shaped needle with a tip and a fixation ligature at one end, characterized in that, in order to reduce the trauma and reduce the time Pull the cut edge to the handle 1. It is 30 the ligature of the needle, the needle is equipped with a mandrel, on the one hand serves as a limiter whose working end is made from advancing the proximal end of mandrel 3 into the slider 4 channel, and on the other, it allows to install mandrel 3 in the basal cavity, located in The non-working end of the mandrel is rigidly connected to a semicircular washer, with 4 handles. When moving the slide 4, the mandrel 3 is pushed out of the groove. Lastly, a thread is brought in, the free ends of which are pulled in the direction of the recess of the groove 6. At this time, the slider 4 moves in the opposite direction. Thus, the mandrel 3 closes the groove 6 outside. The thread is fixed in the channel formed by the walls of the groove 6 and the ground surface of the mandrel 3. In this position, the device is ready for operation. Soft tissue is punctured. Ki mandrin 3 frees the outer edge of the groove 6 and thereby releases the thread. The latter is grasped with forceps, and the needle is removed from the wound channel. Invention Formula A suturing device, comprising a half C-shaped needle with a tip and a fixation ligature at one end, characterized in that, in order to reduce the trauma and reduce the time ligatures, the needle is equipped with mandrin, the working end of which is made with bevel, located in the cavity, and the non-working end of the mandrel is rigidly connected with a semicircular washer, which position, when the pointed edge is rigidly connected to the mandrel drive facing the hole in the side ren, the ligature fixator is made in the wall of the needle 1 and prevents the slit of the semi-oval shape from being displaced to the vertical axis. the mandrel is made in the form of a handle on which a needle is fastened with a screw-Q volume, and a slide made with the possibility of moving along the handle and fixing it with the second The device is used as follows. When suturing the device is held by the hirzfga with the right hand. The thumb is in the ring 9, and the second and third fingers are inside the rings 10, which are connected to the slide 45 with a screw, one ring is rigidly fixed on the end part of the handle, and the second and third rings are rigidly fixed to the sides of the slider. with a screw, one ring is rigidly fixed on the end part of the handle, and the second and third rings are rigidly fixed to the sides of the slider.
