Description

TECHNICAL FIELD The present invention relates to a device for managing suture materials. It finds a particular application in the surgical field. BACKGROUND ART Conventionally, prior to surgery, sutures are placed in their packaging on an instrumentation table, each suture being formed by a needle and a suture thread set on the needle. The package indicates in particular the diameter and the length of the suture.

Thus, when the practitioner wishes to use a wire of specific diameter, he looks for the latter on the instrumentation table by means of the indications which are written on the packaging. Thereafter, the practitioner extracts the needle from its packaging for attachment to a needle holder for suturing a patient.

This practice of looking for a specific suture and then removing it from its packaging and positioning it on a needle holder before use is a considerable waste of time and can have serious consequences for the patient.

In addition, since the suture performed by the practitioner is complete, he puts the needle or the needle holder with his needle on the instrumentation table to, if necessary, be used again. The suture can be used a second time if the remaining length of thread allows it. This length is approximated by the practitioner. This practice nevertheless has disadvantages. The estimated length of the used suture may be wrong. The used thread is then thrown wrongly, this error increasing the cost of the surgical act.

Moreover, when several used needles are disposed on the instrumentation table, that is to say outside their packaging, the practitioner can not differentiate them. In addition, when gripping a used needle, disposed on the instrumentation table, the practitioner may be injured. GENERAL DESCRIPTION The invention aims to solve the aforementioned problems of the state of the art. More particularly, the device for managing suture materials according to the invention aims in particular to eliminate the risk of injury to practitioners. To this end, the invention relates to a device for managing suture materials comprising: a needle support adapted to receive and hold the distal end of a needle for human or animal suture, and differentiation means suture threads. Thanks to the invention, when a suture needle is placed on the management device, it is directly ready for use, identifiable and presents no risk to the practitioner when gripping the needle. In other words, the invention saves time for the practitioner and eliminates the risk of injury for the latter.

For the sake of clarity, only the essential elements for the understanding of the invention have been represented, and this without regard to the scale and in a schematic manner. The same elements in different figures are designated by the same references.

Figure 1 illustrates a non-limiting embodiment of a device 1 for managing suture materials according to the invention.

More particularly, the suture material management device 1 comprises a needle support 2 adapted to receive and hold the distal end 3 of a needle 4 for human or animal suture. More particularly, the needle support 2 is formed of a base 5 covered with a receiving layer 6 of the distal end 3. This receiving layer 6 is made of a material adapted to be perforated by the distal end 3 of a new or used needle without damaging this end 3. The material used may for example be a polyethylene foam.

The device 1 further comprises, on its upper face 10, suture differentiation means 11. In the example illustrated in FIG. 1, the upper face 10 of the needle support 2 is subdivided into four parts 11 ', 11 ", 11-, 11-, the four parts 11', 11", 11 "', 11 - forming these means of differentiation 11. Each of the parts 11 ', 11 ", 11-, 11- corresponds to a type of suture. For example, part 11 'corresponds to a suture with a wire diameter of 0.1 mm and part 11 "corresponds to a suture with a wire diameter of 0.01 mm In non-illustrated examples, each parts 11 ', 11 ", 11"', 11 "" have a specific color to differentiate them and / or an inscription such as, for example, the diameter of the wire used, In such an embodiment, each needle 4 is planted in the support 2 and more particularly in the part 11 ', 11 ", 11-, 11- which corresponds to it so that the practitioner can easily and quickly find the desired suture without being mistaken. In a non-limiting embodiment illustrated in Figure 1, the needle holder 2 is adapted to support a needle holder 7 holding the needle 4 for suturing.

To do this, the needle holder 2 may, for example, include a support 8 on which the needle holder 7 rests when the distal end of the needle 4 is planted in the needle holder 2. This feature is advantageous in that the needle 4 is ready for use by the practitioner and safe for the latter because the tip of the needle is not directly accessible.

In a different embodiment illustrated in FIG. 2, the needle support 2 does not comprise a support 8 so that the needle holder 7 rests directly on the rim 9 of the protective layer 6. In a non-limiting embodiment illustrated on FIG. 3 and 4, the suture material management device 1 comprises measuring means 12 of suture. In the example illustrated in FIG. 3, the measuring means 12 are formed by a measuring band 14, this band 14 being able to be wound around an automatic winder 15 so that the measuring band 14 can be unwound manually and automatically wrapped. In the example illustrated in FIG. 4, these measuring means 12 are formed by a retractable rod 13. In a nonlimiting example, the retractable rod 13 and / or the measuring band 14 comprise two marks 16 each corresponding to a length determined. By way of example, when the practitioner compares the suture with the marks 16, if the suture arrives to: a first mark 16, then the remaining length of thread is sufficient to perform a superficial plane suture - a second mark 16, then the remaining wire length is sufficient to perform a deep planar type suture. In a non-limiting embodiment illustrated in FIGS. 5 and 6, the device 1 for managing suture materials comprises means 17 for collecting suture material.

In the example illustrated in FIG. 5, these collection means 17 are formed by a drawer. In the example illustrated in FIG. 6, these collection means 17 are formed by a receptacle able to pivot along an axis 18, the receptacle having two positions: a first position P1, called storage, in which the receptacle is positioned under the base 5; a second position P2, called collection, in which the receptacle is rotated so that used needles 4 or knife blades 20 are deposited therein. In a particular embodiment, the collection means 17 comprise a magnetized face 19 so that the needles 4 and / or scalpel blade 20 which are deposited therein are retained by the magnetization. In another particular embodiment, the face 19 is adhesive so that the needles 4, the son and / or knife blades 20 that are deposited therein are retained by this adhesive.

In a non-limiting embodiment illustrated in FIG. 7, the suture material management device 1 comprises storage means 22 for scalpel. The storage means 22 are formed by a support 23 comprising at least one rail 24 to receive the blade 20 of a scalpel, these storage means 22 allowing secure storage of the lancets 25. In addition, the storage means 22 comprise by example a maintenance system 26 scalpel. FIG. 8 represents an enlargement of the storage means 22 illustrated in FIG. 7 and more particularly of a particular non-limiting embodiment of the holding system 26, this system 26 is formed by a ball 27 and a spring 28. The spring 28 exerts a thrust P on the ball 27 so that the latter is pushed into the rail 24. Thus, when a blade 20 is inserted into the rail 24, the ball 27 exerts a holding force against the blade 20 via the spring 28. The blade 20 is thus held in position in the rail 24 via the holding system 26.

It is understood that the lancet storage means 22 may comprise a plurality of rails 24 thus offering the possibility to the practitioner of being able to store a plurality of scalpels 25. In a non-limiting embodiment illustrated in FIG. suture material comprises means 29 for separating a handle 30 and a blade 20 of a scalpel 25, the separating means 29 being adapted to collect the blades 20 thus separated. In the example illustrated in FIG. 9, the separation means 30 are formed by a box 31 attached to the base 5. The box 31 has a slot 32. In use, the practitioner introduces the blade 20 of a scalpel for use in this slot 32 until the distal end of the handle 30 comes into contact with the outer wall 33 of the box 31. Then, the practitioner rotates the handle 30 PV up or down so that that rupture occurs between the handle 30 and the blade 20. Once broken, the blade 20 is trapped in the box 31. The handle 30 without the blade 20 can then be discarded without risk of injury. In addition, as illustrated in FIG. 10, the separating means 29 may comprise a flexible element 34. In this embodiment, the blade 20 of a scalpel having an interchangeable blade is introduced into the slot 32 and under the flexible element. 34 until the handle 30 comes into contact with the outer wall 33 of the box 31. Then, the practitioner exerts a downward pushing force EPB on the flexible element 34 so that the flexible element 34 The practitioner then exerts a traction force AND on the handle 30 so that the proximal end 35 of the blade 20 comes into contact with the inner wall 36 of the box 31. By exerting a thrust EPB on the blade 20 and a traction ET on the handle 30, the blade 20 disengages the handle 30, the latter is thus trapped in the box 31. There is therefore no risk of injury to the practitioner.

A new blade 20 can then be positioned on the handle 30 of the scalpel. In a particular embodiment, the suture material management device 1 is for single use and is used for a single surgical procedure.
