Description

Device for holding and releasing an object and corresponding methods

The present invention generally relates to a device making it possible to hold an object, such as a medical implant, and to release said object with respect to this device.

We know from the state of the art and in particular from the international application WO2019030451A2 and from the French patent application filed under the number FR1854199, not yet published on the date of filing of this patent application, object holding devices , also called grippers.

The device presented in the French patent application FR1854199 makes it possible in particular to maintain, using a system of hooks, a screw-type implant which has a head capable of coming into abutment against the system of hooks to prevent the implant to fall to the bottom of the device body.

However, for implants without a head capable of coming into abutment with the device, there is a risk that the implant will slip to the bottom of the body of the device.

It is thus desirable to be able to provide another object holding device for which the object can be held reliably in a given position, while allowing it to be easily released from the device.

To this end, a device is proposed for holding and releasing an object, the device comprising a main body having a housing for at least partially housing said object and an outlet for allowing at least part of the the object,
characterized in that said device for holding and releasing the object also comprises:
- a cover mounted to move between a closed position preventing access to said outlet and an open position releasing access to said outlet,
- an abutment device configured to be movable in different positions relative to the main body in the direction of the exit of said main body, but blocked in the opposite direction, to allow the abutment device to be brought into contact with or close to the object while preventing a recoil of the abutment device.

The device for holding and releasing the object thus makes it possible to offer a lower stop vis-à-vis the object, the position of this lower stop being adjustable to be adapted to the length of the object, while preventing a step back from this lower stop to prevent the object from falling into the main body, which would complicate its extraction.

During the production of the device, that is to say the placement of the object in the device, at least a part of the object is introduced into the body through the outlet of the body which then also serves as introduction passage of the object in the body. Another part of the object, for example a second part distinct from a first part to be introduced into the body through the outlet of the body, can be housed in part in the abutment device.

Access to the outlet of the main body from outside the body is then closed off or hindered by placing the cover in the closed position. Furthermore, prior to the passage in the closed position of the cover, a sealing element can be applied to the body at the level of the outlet of said body.

Once the object has been introduced into the main body, the stop device is then raised towards the object to bring said object to the top stop against the cover, the stop device forming the bottom stop vis-à-vis the object.

The device may also comprise one or more of the following characteristics taken in any technically admissible combination.

According to a particular characteristic, the device comprises a rack system configured to allow said displacement of the abutment device in the direction of the exit of said main body, with blocking in the opposite direction.

According to a particular characteristic, the abutment device is configured to be movable relative to the main body over a distance making it possible to bring at least part of the object projecting from the main body.

According to a particular characteristic, the abutment device has a housing capable of receiving part of the object.

This housing of the abutment device makes it possible in particular, by surrounding said part of the object, to maintain the axial orientation of said part of the object.

According to a particular characteristic, the housing comprises a ring through which at least part of the object is capable of extending, said ring being made of a material different from that of the main body.

This allows the object to be in contact with a material compatible with its own material, for example titanium, without having to make the entire main body of the device in this material which can be expensive.

According to a particular aspect, the ring has an inside diameter slightly greater than the outside diameter of the object which passes through this ring to allow axial guidance without jamming of the object.

Thus, it can be provided that in the open position of the cover and in the absence or in the removed state of a sealing element from the outlet of the body, at least the part of the object which passes through the ring can be exit from the body simply by tilting the exit from the body of the device downwards.

According to a particular aspect, the ring extends set back from the upper end of the main body. Advantageously, said upper end of the main body delimits a passage which can be sealed.

According to a particular aspect, the housing of the object has a part between the ring and the abutment device, which remains open on the inside of the main body.

According to a particular aspect, the housing of the object comprises a skirt which extends at least under the ring, and the abutment device comprises an end part forming a piston adapted to extend in a sealed manner inside the skirt.

The abutment device thus has a part forming a piston configured to be moved inside the skirt, in a sealed manner with respect to the skirt in the direction of the exit from the main body, without possible recoil.

According to a particular aspect, the skirt contains a fluid, preferably a liquid, said object being housed in a chamber defined at least by said skirt and said ring, said chamber being closed in the lower part by the piston of the stop device and in part high by a sealing system.

According to a particular aspect, the outlet of the main body is sealed by a removable sealing system.

According to a particular aspect, the sealing system is coupled with the cover in such a way that the passage of the cover from the closed position to the open position causes the removal of the sealing system.

According to a particular aspect, the device comprises a stabilization system configured to stabilize the cover in the open position and in the closed position.

According to a particular aspect, the cover is configured to, in the open position, remain coupled to the main body by forming a foot allowing the main body to be placed supported by this foot on a surface, while the outlet of said main body is raised relative to this surface.

According to a particular aspect, the cover comprises a centering pin able to come into contact with one end of the object in the closed position of the cover.

According to a particular aspect, said device comprises said object, said object being of the medical type.

According to a particular aspect, said object comprises two separate parts.

According to a particular aspect, said object being of the dental type, said object comprises an implant screw and a healing screw.

In particular, the screw-implant is in the form of an elongated threaded body with a hollow end, but devoid of a head whose width would be greater than the diameter of the screw body.

The invention also relates to a method for producing a device for holding and releasing an object, the device being as presented above, the method comprising the following steps:
- the cover being in the open position, introduction of at least part of the object into the main body through the outlet of said main body;
- Displacement of the abutment device in the direction of the exit of said main body, to prevent or limit the movement of the object in the main body, the recoil of the abutment device being prevented.

According to a particular aspect, said at least one part of the object introduced into the main body through the outlet being a first part, said method comprises, before said step of moving the abutment device, the step of introducing into the device of a second part, said step of moving the abutment device in the direction of the exit of said main body bringing said second part into contact with or close to the first part, the recoil of the abutment device being prevented. The second coin can be introduced before the first coin or vice versa.

According to a particular aspect, said method comprises the step of filling with fluid or liquid a chamber of the main body in which at least a part of said object is housed.

According to a particular aspect, said method comprises a step of sealing the outlet of the main body.

According to a particular aspect, said method comprises a step of closing the cover, before or after the movement of the abutment device.

The invention also relates to a method for releasing an object held in a device as presented above, said method comprising the following steps:
- move the bonnet to the open position,
- Extract at least part of the object through the outlet of the main body using a tool cooperating with said at least part of the object.

According to a particular aspect, said method comprises the steps of:
- pushing the stop device towards the exit of the main body to bring another part of the object close to the exit of the main body, and
- Extract said other part of the object through the outlet of the main body using a tool cooperating with said other part of the object.

The invention also relates to a method for releasing an object held in a device as presented above, said method comprising the following steps:
- move the bonnet to the open position,
- push the stopper device to bring part of the object protruding from the outlet of the main body,

The inventive concept is described more fully below with reference to the accompanying drawings, in which embodiments of the inventive concept are shown. In the drawings, the size and relative sizes of the elements may be exaggerated for purposes of clarity. Like numbers refer to like elements throughout the drawings. However, this concept of the invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. Instead, these embodiments are provided so that this description is complete, and communicates the scope of the inventive concept to those skilled in the art. The following embodiments are discussed, for simplicity, in relation to the terminology and structure of a device for holding and releasing an object, such as a medical implant.

Referring to the figures, there is shown a device 1 for holding and releasing an object. In the examples illustrated in the figures, said object is of the medical type, in particular dental, but could be of another type.

As explained below through different embodiments of the device, said object may comprise one or more parts, for example a medical implant and an accessory part. The device 1 can also be called a gripper. Such a device 1 can be used by an operator to manipulate an object via the device under good aseptic conditions, in particular by using a suitable tool to extract the object.

The device 1 can be housed in a packaging or double-packaging as described in international application WO2014188142 or international application WO2018078242.

The device 1 comprises a main body 10 configured to make it possible to house at least part of said object and a cover 20 mounted to move between a closed position in which it prevents said object from coming out relative to the body and an open position in which it allows the exit of said object or allows access to said object to extract it from the body 10. According to a particular aspect, the open position also makes it possible to introduce or reintroduce at least a part of said object into the body 10.

The body 10 of the device 1 thus has an outlet through which, in the open position of the cover, said object can be taken out.

The device 1 also comprises a stop device 3 which allows the object introduced into the body of the device to be placed in a lower stop, in particular to prevent it from falling to the bottom of the body 10 of the device 1.

The device 1 is configured to allow the abutment device 3 to be moved in the direction of the object (that is to say in the direction of the exit from the body), and to prevent a displacement of the abutment device 3 in the direction of a distance from the object (that is to say preventing movement of the stop device 3 in the direction opposite to the exit of the body).

In the examples illustrated in the figures, the abutment device 3 is formed by a slider 3. The slider 3 is movable along the body 10 to come into contact with the object. Provision may be made for the slider 3 simply to come into contact with the object, but it may also be provided, as in the example illustrated in FIGS. 1 to 11, that a part of this slider has a housing making it possible to receive the lower part of the object. The slider 3 makes it possible to come into contact with the object, in particular to hold the object in position in the body and prevent it from falling to the bottom of the body. The slider 3 thus forms a bottom stop adjustable in position in the upward direction, that is to say in the direction of the exit from the body, to adapt to the length of the object introduced into the body of the device.

According to a particular aspect, the slider 3 is movable over a distance allowing the operator to push the object partly outside the body 10, by moving the slider 3 in the direction of the object, when the cover 20 is in position. opened. As detailed below, this function is particularly useful when the object comprises two parts, one of which is carried by the slider 3. After extracting the first part through the outlet, the second part previously located between the slider and the outlet of the body can end up at too great a distance from the exit of the body to be able to be grasped easily, in particular when the grasping tool comprises a shoulder preventing it from being deeply engaged in the body of the device or risking hindering the exit of the 'tool. The fact of being able to raise the slide again and therefore to bring the second part closer to the exit of the body facilitates the exit operation.

According to a particular aspect, the movement of the slider 3 towards the outlet of the body 10 is limited by a shoulder of the body 10 provided at the level of the upper part of said body 10.

Object lodged in the body of the device

As recalled above and as detailed below through various embodiments, said object may comprise several parts, for example a dental implant and a healing screw.

Provision can be made for the object to comprise at least one implant screw 7 (dental implant), that is to say an elongated threaded body, which preferably passes through a ring 47 as explained below, and optionally comprises an additional part 8, such as a healing screw, preferably housed in part in the slider, which extends between the implant screw 7 and the slider 3. The dental implant 7 is in the form of a threaded body whose upper end located on the side of the output of the body is hollow with an internal shape adapted to cooperate with a tool 9 corresponding input.

In the embodiments of Figures 1 to 11, the object thus comprises a dental implant 7 and a healing screw 8.

In the examples of figures 12 to 15, only the implant 7 is shown. Provision can be made for the implant 7 to be alone or associated with a healing screw as for the embodiments of FIGS. 1 to 11.

Advantageously, in these embodiments of Figures 12 to 15, the dental implant 7 bathes in a fluid, preferably a liquid, contained in a chamber formed by a skirt 173 (for example formed by a tube) in the upper part of the body 10 of the device. Considered as the upper part of the body 10, or the upper part of the slider 3, is the part of the body 10 or the part of the slider 3 which is located on the side of the cover 20 in the closed position of the latter.

Before opening of the cover 20 and/or before pushing on the slider 3 by the operator, the lower end of the skirt 173 is closed by the piston 37 of the slider 3, and the upper end of the skirt 173 is closed by a sealing element 273, such as a peelable strip or sheet, which can be heat-sealed, for example in non-woven synthetic material made from polyethylene fibers, usually sold under the registered trademark TYVEK. The sealing element 273 can also be made of aluminium. Advantageously, in the initial state, that is to say in the closed position of the cover 20 and before displacement of the implant 7 in the direction of an outlet, said implant 7 does not protrude from the upper end of the body 10 towards the outside of the body, but is located just below this end level of the body intended to be covered by the sealing element.

As detailed below, the device 1 in which the implant screw 7 is housed, and possibly the healing screw 8, also makes it possible to release the implant screw 7 which can then be extracted from the device, for example using a suitable tool 9, for example a tool of the screwdriver type, having a tip capable of cooperating with the inside of the head of the implant screw 7, to couple the implant screw 7 to the tool 9.

As detailed below, the implant screw 7 can be repositioned in its housing. In particular, in the case where an operator such as a surgeon needs to put the implant screw on hold to perform another task.

main body

The main body 10 includes an exit passage. The exit passage is located at one end, called the upper end, of said main body 10 to allow the exit of the implant screw 7 and of the healing screw 8 along an exit axis A1. As detailed below, this exit passage is also used to introduce the implant 7 into the body of the device.

The passage through which the implant 7 is introduced into the body 10 and through which it can be taken out of said body 10 can be considered as a through passage which opens into the body 10 opposite the slider 3, and which in certain embodiments can be closed at the bottom by said slider 3, in particular when the passage comprises a skirt 173 as in the embodiments of Figures 12 to 15 and this skirt forms with the slider 3 a chamber in which the implant 7 is immersed.

As mentioned above, the other end of the chamber which contains the implant 7 is preferably closed by an element, such as a sealing sheet or strip, which can be removed at the same time or after opening the cover 20.

In the example illustrated in the figures, the main body 10 has an elongated shape along the exit axis A1 of the implant 7 and of the screw 8.

The body 10 has a bottom wall 100. Advantageously, the output axis A1 extends between the bottom wall 100 and the open front face of said body 10 which is opposite to said bottom wall 100.

The bottom wall 100 has an inner face 101 provided with ribs 13 along which the slider 3 presented below is configured to be able to slide in the direction of the upper part 17 of the body 10.

As visible in FIG. 3 and in FIG. 11, a window 103 can be made through the bottom wall 100 to allow the presence of the object to be viewed from the outer face 102 of said bottom wall 100. The implant 7 extends from the side of the inner face of the bottom wall facing said window. It can be provided that the window 103 is not present.

Advantageously, the body of the device, and/or the cover and/or the slider is or are transparent or translucent.

The body 10 of the device has a peripheral wall 104 which extends transversely, preferably orthogonally, to the bottom wall 101, by which the operator can grasp the body of the device. Advantageously, the opposite lateral sides of said body 10 each have a recessed curved part to facilitate gripping of said body of the device by the operator.

Sliding system of the slide relative to the body

As mentioned above, device 1 for holding and releasing the implant comprises a sliding system for slider 3 relative to body 10 of device 1.

As illustrated in Figures 3 and 6, the sliding system comprises two parallel rails 13, preferably formed on the bottom wall 100 on the inside of the body. For this purpose the abutment device 3 is provided with grooves 31 (or grooves) cooperating with said rails. Of course, the rails 13 (ribs) could be carried by the slider 3 and the grooves or grooves could be formed in the body 10.

In the example illustrated in the figures, the body 10 has a notching system, such as a rack system, configured to allow movement of the slider 3 towards the upper end of the body 10 at which the object is located. , but preventing movement of the slider 3 in the opposite direction. In the example illustrated in the figures, the rack system comprises for each rib 13 a rack 132 secured to said rib 13.

In particular, in the view of figure 6, part of the slider 3 has been indented in its middle zone to show the sliding system between the slider 3 and the body 10 of the device 1.

The slider 3 is provided with teeth 32 capable of cooperating with the teeth of the rack. The teeth of the rack 132 of the body 10 and the teeth 32 of the slider 3 are oriented so as to allow movement of the slider 3 only towards the upper end of the body of the device.

Upper part of the device body

According to embodiments, the upper part 17 of the body 10 of the device 1 at the level of which is located the inlet/outlet passage of the implant 7 comprises a ring 47 (also called collar) attached to a corresponding housing provided in the upper part 17 of the body 10 of the device 1.

Figure 4 shows in axial section the upper part 17 of the body of the device, which shows the system for pivoting the cover relative to the body, as well as the ring 47.

The ring 47 is made of a material different from that of the body of the device 1. Advantageously, the ring 47 is made of a material of the same family or identical to that used for the implant 7. Advantageously, the implant 7 and the piece 8 are also made of a material of the same or identical family. Thus, provision can be made for the body 10 of the device to be made of plastic, while the ring 47 is made of titanium, the implant 7 being made of titanium.

Such a ring makes it possible to guide the implant while preventing the implant from coming into contact with a material that would not be compatible with that of the implant.

In the examples illustrated in the figures, the upper part 17 comprises in particular a seat 171 configured to receive the ring 47. A wall wall 170 at least partially surrounds the seat 171 to delimit the housing for receiving the ring 47. The ring 47 is preferably mounted by force in the corresponding receiving housing of the body 10.

The seat 171 has a through passage aligned with the through passage of the ring 47. The implant 7 is thus able to extend through the ring 47 and through the through passage of the seat 171.

In other words, the body 10 thus has a housing making it possible to contain at least a part of the implant 7. The through passages of the ring 47 and of the seat 171 form part of this housing through which the implant 7 can be introduced. and released relative to the body 10.

Preferably, the internal diameter of the ring 47, which is slightly greater than the external diameter of the implant, is slightly smaller than that of the seat 171 (and of the skirt 173 when it is present as detailed below) to limit the risk of contact of the implant 7 with the material of the body of the device.

In the embodiments of FIGS. 1 to 11, and in the closed position of the cover 20, a part of the implant 7 thus extends below the seat 171 for receiving the ring 47 while being visible to an operator with a view to face of the body, in particular because the front face of the body (opposite to the bottom wall) is open. Implant 7 is in contact with part 8 which is partly received in the upper part of slider 3.

In the embodiments of Figures 12 to 15, and in the closed position of the cover 20, the part of the implant 7 which extends below the seat for receiving the ring 47 is surrounded by the skirt 173 inside which is engaged the upper end of the slider 3 which forms a piston.

The upper part 17 of the body 10 thus has via the ring 47 and the through passage of the seat 171, an opening, called opening for insertion/release of the implant 7 (the upper part of which can be sealed in the waiting for the cover to open). As mentioned above, this opening also allows the exit of the screw 8, and the slider 3 can be moved to bring the screw 8 closer to this exit opening if necessary.

The insertion/release axis or exit axis A1 of the implant 7 corresponds, in the example illustrated in the figures, to the longitudinal axis of the body 10 of the device.

In other words, when the operator holds the device facing him, that is to say with the pivoted cover 20 oriented towards him, the insertion/release opening presented by the body of the device is located substantially on the side of the operator.

The fact that one end of the object extends into the body and that the other end is capped by the cover in the closed position of said cover, allows good support and good protection of the object.

Hood

In the example illustrated in the figures, the cover 20 comprises a general inverted U shape.

The cover 20 thus has two arms 21 interconnected by a connecting part 22 capable of being grasped by an operator's hand. Cover 20 is coupled to body 10 by its arms 21.

As illustrated more particularly in Figures 8 and 3, each arm 21 is provided with an element 211, for example a male element in the form of braces, capable of cooperating with a corresponding female element 121 of the body 10, to allow the cover to pivot. 20 compared to body 10.

The pivoting of the cover 20 takes place around an axis A2 orthogonal to the output axis A1 of the object with respect to the body 10. In particular in the example illustrated in the figures, the axis A2 of pivoting is parallel to the mean plane of the body (or even to the mean sliding plane of the slider 3).

The pivoting elements 211,121 made on the cover 20 and on the body 10 allow the cover 20 to pivot relative to the body 10, on either side of the output axis A1. In other words, the cover 20 can be pivoted to one side or the other of the mean plane of the body 10 which passes through this output axis A1.

The connecting part 22 of the cover 20 has an inner edge which, in the closed position of the cover 20, is located opposite the outlet passage 107 of the body 10. As illustrated more particularly in FIG. 10 and in FIG. inner edge of cover 20 is provided with a projecting relief 27 in the direction of said outlet passage, preferably of convex curvature, for example in the shape of a hemisphere, to cooperate with the hollow end of implant 7, and thus ensure the axial centering of the implant in the outlet passage.

Hood position indexing system

The closing and opening positions of the cover 20 are stable predefined (discrete) positions. In other words, the operator must exert a force beyond a threshold value to pivot the cover 20 from one position to another.

In the closed position, the cover 20 makes it possible to prevent or hinder the access of the operator to the object in order to prevent an untimely exit or deterioration of the object.

Part of the pivoting mechanism between the cover 20 and the body 10 is provided on the upper part 17 of the body 10 of the device. In particular, in the example illustrated in the figures, said pivoting mechanism part is located close to the receiving seat 171, and comprises two elements 112 distributed on either side of said seat 171 on the upper lateral edges of said body 10 .

In the example illustrated in the figures, the pivoting mechanism has a position indexing system which makes it possible to pivot the cover 20 into positions where it is held (stable), preferably both for the pivoting of the cover 20 in a direction than in the other.

The hood 20 indexing system also offers an indexing position corresponding to the closed position of the hood 20, which makes it possible to maintain the hood 20 in this closed position, as long as the operator does not force the passage of the hood 20 in another indexed position, corresponding to an opening position of the hood, in one direction or the other.

These stabilized positions of the cover are obtained in the example illustrated in the figures, by at least one arm of the crosspieces which is provided with a tooth 211A (visible in FIG. 8) able to engage in the recesses 121A of an element 121 provided on the body 10 (see Figure 3), depending on the angular position of the cover 20 relative to the body 10. For this purpose the element 121 has three hollow spaced angularly from each other according to the desired stable closing positions , opening on one side and opening on the other side.

Thus, by turning the cover 20 relative to the body 10, the cover 20 is brought into a new stable position indexed by cooperation of the tooth 121A of each spider 121 with one of the hollows 122A of the corresponding element 121 of the body 10.

The elements 211, 121 for pivoting and indexing in position can be distributed equally over the cover 20 and the body 10. Thus in the example illustrated in the figures, the spiders are carried by the arms 21 of the cover 20 while the housings complementary to these braces are provided on the body 10. But a distribution of the braces on the body and additional housings on the arms of the cover can also be provided.

The connecting part 22 of the cover 20 has a flat part capable of carrying an inscription, such as a logo, making it possible to personalize said cover.

The operator can thus pivot the cover 20 into a predefined stable opening position, preferably on either side of the body of the device. The cover 20 thus pivoted forms a foot through which the device can rest on a resting surface, such as a table, so that the body of the device is inclined with respect to the resting surface as illustrated in FIG. 19. Advantageously, the body of the device is inclined relative to the laying surface by an angle of the order of 30°. It will be understood that this angle depends on the length of the body and on the predefined stable pivoting positions of the cover 20 with respect to the body 10 of the device. Preferably, the cover forms in the open position an angle of 90° with respect to the body 10.

The upper part 17 of the body 10 through which the implant 7 is intended to be taken out is thus moved away from the laying surface of the device.

Slider

The mobility of the slider makes it possible, as mentioned above, to adjust the position of the slider to the position and therefore to the length of the object formed by all of the parts 7, 8 so that the parts 7 and 8 can bring the one in contact with the other by raising the slider until the upper part 7 is brought into contact with the cover 20 (in the absence of a sealing element between the cover and the outlet opening of the body).

The configuration preventing the slider from moving back makes it possible to ensure that the object 7, 8 is trapped between the slider 3 and the cover 20 as long as the latter is not brought into the open position, which prevents any or part of the object falls to the bottom of the body 10 or into an area of the body 10 not provided for housing the object.

The slider 3, in the state reassembled against the parts 7, 8, forms a lower stop while the cover (or an intermediate sealing element as described below) forms an upper stop.

In the open position of the cover, the slider 3 also makes it possible to push the object formed from all the parts 7, 8 along the axis A1 in the direction of bringing the end of the part 8 closer together. which is in contact with the slider 3, towards the upper part 17 of the body, with a view to extracting the implant screw 7 and the healing screw 8 from the body 10.

In this exit position of the slide 3 and in the extracted state of the part 7, the part 8 of the object is close to and opposite the through passage of the ring 47, which allows the operator to grasp part 8 using a tool 9' passing said tool through 47.

According to certain embodiments, the cover 20, the body 10 and the slider 3 are configured so that the length of the implant, that is to say at least its ends, remains visible. The length of the implant can thus remain visible at least for the operator who looks at the device in front view, that is to say from the side of the slider, in the normal configuration for gripping the device.

The slider is provided with a zone 39 for positioning a finger, also called an imprint, for example comprising recessed or raised surface irregularities, such as ribs or grooves, facilitating the sliding movement of the slider 3 by the operator.

Upper part of the slider

The slider 3 has an upper part 33 which corresponds to the end part of the slider 3 oriented towards the outlet passage 107 of the body 10.

As visible more particularly in Figure 2 and in Figure 9, the upper part 33 comprises a receiving part 38 which makes it possible to receive part of the part 8.

In the example illustrated in Figures 1 to 11, the receiving part 38 has a funnel shape and the end of this part 8 opposite the implant is located opposite and/or in contact with a part 338 of the slider forming a lower stop for part 8. Part 338 thus makes it possible to stop part 8 so as to limit or control its insertion into slider 3 in order to retain part of part 8 which extends projecting from the slider, particular protruding from the funnel 38 to come into contact with the part 7.

Example of use for the embodiments of Figures 1 to 11

In the example illustrated in Figures 1 to 11, during production of the device with introduction of the screw-implant 7 and the healing screw 8 into the body of the device, the healing screw 8 can be introduced into the corresponding housing 38 of the slider 3, without having to pass through the ring 47, for example by being introduced from the open face of the body of the device into the upper end of the slider 3 which is then in the low position, that is to say at near the lower end of the body 10.

Then the implant screw 7 can be introduced into the upper part of the body 10 through the corresponding exit passage 107 (see FIG. 3), in a position where the upper end of the screw is located close to the upper end of the body , and where the ring 47 surrounds said implant screw (In other words, the implant screw does not extend entirely below the ring).

The cover 20 can be closed to form an upper stop vis-à-vis the implant screw 7. The implant screw 7 and the healing screw 8 are then brought into contact with each other by raising the slider 3 in direction of the implant screw 7, which also causes the implant screw 7 to abut against the cover 20.

During the operation to remove the implant 7, the implant 7 is extracted without driving the healing screw 8. As illustrated in Figure 10, the healing screw 8 remains supported by the end part 33 of the slider 3 and can be extracted from the body once the implant screw 7 has been extracted. In other words, in the examples illustrated in the figures, there is no particular mechanical coupling between the implant screw 7 and the healing screw 8.

A device corresponding to that illustrated for example in FIG. 1 is thus obtained.

When the operator wishes to extract the parts 7.8 from the device 1, he can then open the cover 20 to access the implant 7 through the outlet of the body 10, by removing the implant 7 for example with the tool 9 which is adapted to be coupled to the implant, for example by coupling a male end of the tool with the hollow end of the implant 7.

As illustrated in Figures 7, 9, the operator can also push the slider 3 to bring out the implant 7 and grasp it. It should be noted that such an exit of the implant 7 by pushing the slider 3 makes it possible to grasp the implant, manually or using a suitable tool, by its outer periphery.

As illustrated in FIG. 10, the thrust on the slider 3 makes it possible to bring the part 8 close to the outlet of the body 10. In particular, the operator can then pass a suitable tool 9' through the ring 47 to go look for part 8 and extract it from the slider and the body.

It should be noted that the high thrust position of the slider 3 facilitates the extraction of the healing screw because otherwise the collar 90' of the tool 9' could hit against the ring 47 or the seat 171 of the ring while trying to bring out the tool 9' entered too deeply into body 10 of device 1.

Example of use for the embodiments of Figures 12 to 15

In the examples of Figures 12 to 15, the piston 37 of the slider 3 is introduced into the lower part of the skirt 173. It is possible to provide that the piston also has a suitable shape, for example like the shape of the upper part 33 with funnel 38 and the bottom stop 338 of the embodiment of FIG. 2, so as to receive a part, such as part 8 presented in the embodiments of FIGS. 1 to 11, while retaining a piston function, this is that is to say with a peripheral periphery adapted to be moved in a sealed manner inside the skirt 173.

In particular, provision can be made, as illustrated in FIGS. 16 to 18, for sealing to be ensured by a peripheral element formed by a peripheral part of the edge of the piston head with a semicircular section 371 (FIG. 16), with a quarter-round 371' (with curvature oriented inwards at the top) (Figure 17) or formed by a seal 6 (Figure 18), preferably of circular section, housed in a peripheral groove made in the song of the head of piston.

An axial groove or throat can be made in the ring to facilitate the expulsion of air when the piston 37 is introduced into the skirt 173.

The implant 7 is introduced into the skirt 173 through the outlet of the body 10 passing through the ring 47. Advantageously, part of the implant remains surrounded by the ring 47.

According to a particular aspect, the chamber delimited at least by the skirt 173 and the piston 37 is filled with liquid, for example a solution of sodium chloride which can make it possible to maintain a highly hydrophilic state at the surface of the implant, or a tensio -active allowing to maintain an active and unmodified surface state by contact with the air, or else an osteo-promoting doping element, for example a solution of BMP (BMP for Bone Morphogenetic Protein in English), or even an element disinfection / bactericidal prevention (Silver ion solution or others, etc.), in which the implant 7 then bathes. The outlet of the body 10 is in this case sealed to contain the liquid and the cover can be brought into the closed position by look at the exit.

The operator who wishes to extract the implant 7 and the part 8 when it is present, can then open the cover, and, preferably simultaneously, remove the sealing element 273, in order to be able to access the screw. Implant 7 (and part 8 when present) can then be removed as explained above using a suitable tool 9 with or without pushing slider 3.

Pushing slider 3 also releases the liquid in which the implant is bathed, like a syringe whose piston would be piston 37.

Preferably, the sealing element 273 used is attached to the cover 20, so that the opening of the cover 20 causes the removal of the sealing element 273 with respect to the outlet from the body of the device. Thus, the representation of the cover being opened in FIG. 12 reveals the upper end of the implant 7 which is surrounded by the ring 47 and the skirt 173, the sealing element 273 of the upper end of the implant housing being undone or withdrawn relative to the body 10 at the same time as the cover 20 opens.

As a variant, provision can be made for the sealing element not to be linked to the cover and for it to be removed manually to free the outlet of the body 10 and thus open the chamber which contains the implant 7.
