Description of Patent for Industrial Invention with title: "SURGICAL ASPIRATOR FOR PLASTIC SURGERY".

DESCRIPTION

The present invention refers to a surgical aspirator for plastic surgery.

In the surgery sector? note the need to remove residues of various kinds from surgical sites during an operation on a patient.

Specifically, for ?surgical site? refers to an area of the patient's body subject to surgery, which is accessed after incision of the external tissues.

With particular reference to the sector of additive plastic surgery, such as mammoplasty, gluteoplasty, zygomoplasty, etc., these residues are mainly composed of organic and/or silicone residues of a viscous and/or semi-solid type, deriving from the prostheses generally used for the operation .

In fact, following an initial implantation of these prostheses, ? It is possible that these may become torn, for example following trauma, and need to be removed and possibly replaced.

During this second operation the surgical site is opened again and the original prosthesis is removed. In particular ? It is extremely important that any residues generated by tearing the prosthesis are completely removed.

The permanence of such residues within the surgical site can, in fact, cause infections or infiltration of the same into the surrounding tissues.

For this purpose, suction devices are known that can be inserted inside the surgical site during surgery and configured to remove the aforementioned residues.

Suction devices of the known type generally consist of a deformable tube provided with an end insertable inside the surgical site and one extremity? opposite connected to suction means configured to generate a suction force inside the tube itself to allow the removal of such residues.

Known suction devices, however, present some drawbacks, among which is the fact that they do not allow effective suction of viscous residues to free the surgical site from them.

Silicone, in fact, is a viscous material that adheres to tissues and other operating instruments.

In fact, precisely because of the nature of this material and the high volume to be aspirated, it is It is common for known types of suction devices to become clogged and cannot be used continuously. during surgery.

In these cases, in order to replace or unclog the extractor, it is It is necessary to interrupt the operation, significantly lengthening the operating times.

Furthermore, contamination of surgical instruments leads to further interruptions aimed at cleaning and sterilizing them.

To at least partially overcome these inconveniences, ? The use of syringes comprising a main body provided with a connection for a needle and a plunger slidably engaged with the main body to generate a suction force through this connection is known.

According to one modality? In traditional use, the syringe without the needle is applied with the fitting at the surgical site and the viscous residues are pre-washed through the fitting itself and stored in the main body until the latter is filled. Once filled, the syringe must be replaced with a new one in order to continue the aspiration operations.

In a different mode? of use, the syringe can be deprived of the piston and connected to suction means through the fitting. In this way the syringe is used inverted and the aspiration is performed by placing the upper edge of the main body in correspondence with the surgical site.

Although? these solutions make it possible to reduce at least part of the obstruction problems, however, it is clear that the use of syringes is decidedly impractical.

First of all, according to the modality? of traditional use, in order to use the syringe correctly? It is essential to use both hands. It follows that? It is necessary to provide an operator intended only for this purpose and this? can? be an obstacle, especially in the case of complex surgical operations in which it is a large number of healthcare personnel are expected.

At the same time, according to the modality? When used inverted, the syringe does not allow the aspirated residues to be retained inside the main body with the risk of continuous spills inside the surgical site.

Furthermore, the syringes normally available on the market have a capacity maximum of approximately 50-60 cc and also imply continuous interruptions of the intervention in order to replace and/or empty them.

In addition to the aforementioned drawbacks, ? It is clear that the syringes do not fully satisfy the required safety requirements.

In fact, the contact of the fitting or the upper edge of the main body with the surgical site can cause damage or lacerations to the surrounding tissues which can lead to an increase in operating times and a consequent increase in wound healing times.

The main task of the present invention is? that of devising a surgical aspirator for plastic surgery that allows the removal of even large quantities of residues, avoiding interruptions in the surgical procedure.

Another purpose of the present invention? that of devising a surgical aspirator for plastic surgery that is practical to use and allows effective removal of residues.

A further purpose of the present invention? that of devising a surgical aspirator for plastic surgery that reduces the risk of contamination and/or infections of the surgical site and that guarantees aseptic conditions during use.

Another purpose of the present invention? that of devising a surgical aspirator for plastic surgery that allows to reduce the operating and healing times of the surgical wound.

Other purpose of the present invention? that of devising a surgical aspirator for plastic surgery which allows the aforementioned drawbacks of the known art to be overcome within the context of a simple, rational solution that is easy and effective to use and has a low cost.

The above objectives are achieved by the present surgical aspirator for plastic surgery having the characteristics of claim 1.

Other characteristics and advantages of the present invention will be more evident from the description of a preferred, but not exclusive, embodiment of a surgical aspirator for plastic surgery, illustrated by way of example, but not by way of limitation, in the attached drawings in which:

figure 1? an axonometric view of a first embodiment of the surgical aspirator according to the invention;

figure 2? a longitudinal section view of the surgical aspirator in figure 1;

figure 3? an axonometric view of a second embodiment of the surgical aspirator according to the invention;

figure 4? a longitudinal section view of the surgical aspirator in figure 3;

figure 5? a schematic representation of an apparatus comprising the surgical aspirator according to the invention.

With particular reference to these figures, yes? indicated globally with 1 of the surgical aspirator for plastic surgery configured for the removal of viscous and/or semi-solid organic and/or silicone residues. In the context of this discussion, with the expression ?organic and/or silicone residues of a viscous and/or semi-solid type? does it mean residues present in a surgical site, in organic and/or silicone material and which by their nature have high viscosity? and have a fluid and/or semi-solid consistency. In detail with reference to the term ?semisolid? we are referring to materials that can exhibit liquid (viscous) or solid (elastic) behavior depending on the temperature to which they are subjected. For example, ? this is the case of additive prosthetics.

Again, with the expression ?surgical site? refers to a portion of a patient's body subjected to surgery and which is accessed after incision of the external tissues.

In particular, in the remainder of this discussion, we refer preferably, but not limitedly, to additive plastic surgery interventions, such as mastoplasty, gluteoplasty, zygomoplasty, etc., through which prostheses made of organic and/or silicone material are inserted into the Inside the surgical site. This type of intervention further includes the removal/replacement of prostheses following trauma which can cause them to tear, generating the aforementioned viscous and/or semi-solid residues, which must be removed in order to avoid the subsequent onset of infections. .

The surgical aspirator 1 according to the invention comprises at least one hollow body 2 comprising at least one cavity collection 3 of residues in viscous and/or semi-solid organic and/or silicone material.

Hollow body 2 includes:

- at least one insertion portion 4 configured to be introduced at least partially inside at least one surgical site containing the residues and comprising at least one suction mouth 5 for the residues; And

- at least one connection portion 6 opposite the insertion portion 4 and including at least one connection hole 7 to suction means 8 to allow the removal of residues from the surgical site.

In particular, the suction mouth 5 and the connection hole 7 are in fluid communication with the cavity. of collection 3.

The suction means 8, of the type for example of a pumping system, generate a suction force such as to suck the residues through the suction mouth 5 into the cavity. of collection 3.

The surgical aspirator 1 therefore allows the removal of residues from the surgical site and, at the same time, thanks to the presence of the cavity collection 3, allows you to reduce the risk of possible obstructions at the suction mouth 5.

In fact, once aspirated, the residues immediately pass into the cavity. collection 3 avoiding obstruction of the suction mouth 5.

Conveniently, the insertion portion 4 and the connection portion 6 are coaxial with each other.

Specifically, as shown in the figures, the hollow body 2? of elongated shape and the suction mouth 5 and the connection hole 7 are arranged along the longitudinal median axis A of the hollow body 2.

The arrangement of the suction mouth 5 and the connection hole 7 allows you to define a straight suction direction, favoring the complete and effective removal of residues.

The hollow body 2 has a proximal bottom wall 9, arranged in correspondence with the insertion portion 4, and a distal bottom wall 10, arranged in correspondence with the connection portion 6. In the context of this discussion, with the terms "proximal ? and ?distal? reference is made to the position of the surgical aspirator 1 with respect to the surgical site during use. In particular, the proximal back wall 9? the back wall more? close to the surgical site while the distal back wall 10? the back wall more? far away.

The suction mouth 5 ? associated with the proximal bottom wall 9 while the connection hole 7 is associated with the distal back wall 10. Pi? in detail, the suction mouth 5 and the connection hole 7 project outwards from the respective bottom walls 9, 10.

In the embodiment shown in the figures, the connection hole 7? associated integral with the distal back wall 10.

However, it cannot be excluded that the connection hole 7 is removably associated with the distal bottom wall 10.

For example, connection hole 7 can? be associated by interlocking or screwing to the distal back wall 10.

The connection hole 7 ? substantially frusto-conical in shape with a section decreasing away from the distal bottom wall 10. The shape of the connection hole 7 favors its connection to the suction means 8.

? It should be specified that the connection to the suction means occurs via systems known to those skilled in the art, for example via tubes which are fitted onto the connection hole 7.

With reference to the embodiment shown in the figures, the suction mouth 5 has a substantially cylindrical shape and has a smaller diameter than the extension of the proximal bottom wall 9. The shape of the suction mouth 5 allows you to easily reach every point of the surgical site favoring effective, precise and homogeneous removal of residues.

The suction mouth 5 includes a contact edge 11 intended, in use, to contact the surgical site.

Helpfully, the contact edge 11 ? arranged marginally with respect to the suction mouth 5 and has a rounded circular profile.

This conformation makes the extremity more blunt. of the suction mouth 5 which, by coming into contact with the surgical site, reduces the risk of cuts and injuries to the surrounding tissues.

In addition, the contact edge 11 includes a protruding perimeter edge 12 suitable, in use, to touch the walls of the surgical site.

The protruding perimeter edge 12 has the function of helping to keep the surgical aspirator 1 inside the surgical site during the operation.

More? in detail, the protruding perimeter edge 12, during use, interacts with the walls of the surgical site, which adhere to it and keep it inside the surgical site itself.

Does the contact edge 11 include a cavity? anti-spill 13 with a concave shape facing towards the cavity? of collection 3, which develops along the circular profile and is intended to avoid falling from the cavity? collection 3 at the surgical site, of the previously aspirated residues. More? in detail, the contact edge 11 has a curved shape and defines a concavit? facing the cavity? of collection 3.

In practice, during use, the cavity? anti-spill 13 allows you to collect any residues that may escape due to gravity? from the cavity? of collection 3.

In addition, the suction mouth 5 can? be made at least partially of a soft material.

In the context of this discussion, for ?soft material? we mean an elastically deformable material, for example silicone, and therefore capable of being at least partially deformed following contact with the surgical site.

More? in detail, at least the contact edge 11 ? made of soft material.

As shown in the figures, the hollow body 2 includes at least a central median portion 14 interposed between the insertion portion 4 and the connection portion 6.

In particular, the central median portion 14 has the function of facilitating the grip of the surgical aspirator 1 and increasing its practicality. of employment. Furthermore, the central median portion 14 in turn defines the cavity of collection 3 and allows to give a high capacity? to the hollow body 2.

Specifically, the hollow body 2 has a volume between 500 cc and 600 cc.

Conveniently, at least the insertion portion 4 and the central median portion 14 have a substantially circular cross-section and the insertion portion 4 has a diameter greater than the respective diameter of the central median portion 14.

In the preferred embodiment shown in the figures, the connection portion 6 also has a substantially circular cross-section. This construction solution provides that the connection portion 6 also has a diameter greater than the respective diameter of the central median portion 14.

In particular, the fact that the insertion portion 4 and the connection portion 6 have a larger diameter than the central median portion 14 gives the aspirator 1 an ergonomic shape which further improves its handling and movement within the site surgical.

More? in detail, this geometric shape guarantees an optimal grip of the surgical aspirator 1 and reduces the risk that it may slip from the operator's hands during use; at the same time, there? allows the surgical aspirator 1 to be extremely compact in size while maintaining a high capacity. collection.

Usefully, at least the central median portion 14? made of a rigid material.

With the expression ?rigid material? we mean a material that is not deformable during handling and which therefore allows the hollow body 2 to be firmly gripped and allows for its precise application in the surgical site.
