Definitions
- the invention relates to the laparoscopic surgical treatment of a pneumothorax characterized by detachment of the parietal pleura from the thorax.
- the treatment includes an abrasion or scraping phase during which the surgeon laparoscopically infuriates the parietal pleura which adheres to the sides with an abrasive material, so that the resulting bleeding generates, by healing, adhesions facilitating the subsequent bonding of the skin. parietal pleura with the visceral one.
- Document FR2981840 discloses a pleural abrasion device comprising:
- tubular body surrounding the longitudinal body and arranged in a handle
- the brush can be moved between a storage position, in which it is retracted into the tubular body, and a working position, in which it protrudes out of the free end of the tubular body, and is animated by a scraping motion , for example rotary.
- these strands or bristles are made of polyamide material, such as that known under the trademark "NYLON", the abrasion obtained is weak and difficult to control by the surgeon during operation.
- the strands are oriented transversely on the side and / or longitudinally end, and allow to perform the brushing in two perpendicular directions, which is very insufficient for the surgeon working on curved intermediate parts with a tool whose The orientation of the scraping means is limited and can not be modified because of its guidance along the longitudinal axis of the trocar.
- the replacement of polyamide strands or bristles by strands of rigid material could improve the scratching power of the end of the strands, but not their stiffness which depends on their free length, that is to say a parameter which, in the current brushes, is neither adjustable nor controllable by the surgeon during operation.
- the invention aims to remedy these drawbacks by providing a disposable brush arranged to ensure the abrasion of the pleura by "pleuroscopy", without requiring preparatory operations using means of abrasion imperfectly sterile and allowing to adapt during the operation, the stiffness and the orientation of the scraping.
- the means for moving the longitudinal body carrying the strands are constituted by a slider, manually actuated and secured to the rear end of the longitudinal body, said slider being movable in a light longitudinal and cooperating with indexing means carried by the edges of this light, while the strands of rigid material are provided with elastically deformable bowls and having different radii of curvature, so as to form, when they are retracted into the body , a bundle of parallel strands and, when in working position, out of the tubular body, a flat fan blade, the strands of which extend laterally from the longitudinal axis.
- the brush is provided with its strands in the storage position, that is to say, fully arranged, parallel and in the case formed by the end of the tubular body. This allows it to be engaged in the reduced diameter trocar to bring it close to the scratch area, without these strands clinging to the vital organs of the patient, such as lungs and heart.
- the surgeon decides that the action position is reached, with the help of the indexing he makes all or part of the strands of the tubular body to form a brush having the rigidity, that is to say the "nerve” required and whose strands form a fan extending from the longitudinal axis of the brush to the laterally inclined strand.
- the removal of the brush is done quickly, after bringing the strands in their case, not to pollute the operated area.
- the handle of the brush contains inner slides on which the slide can move.
- the angle ⁇ of the fan formed by the strands measured between, on the one hand, a strand B1 parallel to the longitudinal axis of the body carrying the strands and, on the other hand, the most arched strand B2 on the side, has a value that goes from 180 degrees to 90 degrees as the strands move away from the B1 strand parallel to the longitudinal axis.
- Figure 1 is a perspective view, when in use position strands out
- Figure 2 is an exploded perspective view of the brush of Figure 1;
- Figures 3, 4 and 5 are side views in section on an enlarged scale, respectively III-III and IV-IV of Figure 1, the strands being partially extracted in Figure 4 and fully taken out in Figure 5;
- Figure 6 is a partial view of an alternative embodiment of the brush strands allowing them to form a fan on substantially 90 degrees;
- Figures 7 and 8 are views respectively in section and elevation of the brush of Figure 6 in the working position, with the strands out to the maximum.
- reference numeral 1 designates the scraping member, 2 a longitudinal body, 3 a tubular body in which the first can slide, 4 a displaceable slide in a two-part sleeve 5a -5b, and 7 the strands forming the brush.
- the tubular body 3 is connected by its rear end to the handle 5a-5b. It has a circular section and extends over a length of the order of 280 millimeters, so that when its front end 3a is near the scraping zone, the handle is out of the chest for all the morphologies that can be encountered.
- the longitudinal body 2 has a cylindrical section allowing it to slide in the tubular body 3 with reduced radial clearance.
- the front end 2a of the body 2 is bonded, by gluing, welding or soldering, to the posterior ends 7b of the strands 7, made of metal.
- the longitudinal body 2 is secured to the slider 4 slidably mounted in slides 8 of the two-part handle 5a-5b.
- the slider 4 passes through a slot 9 formed in the handle and thus forms a slider for adjusting the position of the strands 7, between a retracted storage position in the tubular body 3, as shown in FIG. 3, and a fully working position position, shown in Figure 5.
- the slide 4 also carries elastic tongues 10 cooperating with notches 1 1 formed on the edges opposite the light 9.
- Tabs 10 and notches 1 1 can also form indexing means, but in a variant the indexing function is provided by a transverse index 15 carried by the slider 4 and can be moved in front of graduations 1 6 formed on the edges of light 9. Means 15 and 16 are very visible by the operator and complete the tactile sensation he perceives by the engagement of the tabs 10 in the notches 1 1.
- the surgeon knows the position of the brush relative to the handle and in relation to the engagement of this tool in the body.
- the operator can, as shown in FIG. 4 for a mid-stroke exit, obtain a stiffness different from that obtained by a complete output of the strands, shown in FIG. , and can therefore adapt this stiffness to the needs of the scratching of the parietal pleura.
- the two parts 5a-5b of the handle are obtained by molding or machining of plastic material, or any other rigid material, and assemble in the longitudinal median plane of the handle. They are connected to each other by transverse screws screwing into the wells 12, shown in Figures 3 to 5. In a variant the two half-shells are bonded by bonding, brazing or welding.
- the strands 7 of the brush are provided with camber 13 having different radii of curvature so as to form, when they are juxtaposed in the working position, as shown in FIGS. 4 and 5, a fan-shaped broom whose strands are distributed on a plane. They extend between a strand B1, arranged parallel to the longitudinal axis of the brush, and a strand B2 projecting laterally.
- the angle ⁇ has a value of the order of 30 degrees, as shown in FIG.
- Figures 4 and 5 show that the longer the length of the strands out is greater, the greater is the angulation of the formed planar fan and increases their flexibility, so decreases their stiffness. It also shows that the more the strands are out, the more they laterally deviate by increasing the spatial extent of scratching.
- the strands are made of stainless steel wires having a diameter of between 0.15 and 0.40 mm.
- the surgeon can thus, during his operation of abrasion of the pleura, modify the extent of the fan obtained, to adapt it to the surface to be scratched, as well as the stiffness of the brush, by simple manual movement of the slide 4 by report to the handle. This is an important advantage that can not be achieved with the current means.
- the strands 7 form a fan extending over a larger angle, of the order of 90 degrees between said strands. B1 and B2.
- the ends of the strands 7 can provide effective scraping over the entire periphery of the fan, both by the extreme strands B1 or B2 and by the intermediate strands. .
- the largest angular opening of the fan does not disturb the operation of retraction of the strands in the tubular body 2, since, by the elasticity of their camber 13, these strands are folded longitudinally against each other.
