Definitions
- the present invention relates to a discharge device for discharging a poorly fluid mass, in particular a bone graft material, with a housing and a container insert arranged therein, wherein a lateral recess is formed in a housing wall of the housing a container container wall of the container insert, a lateral container opening is formed, and wherein the container insert relative to the housing between a closure position in which the housing wall closes the lateral container opening, and a release position in which the lateral recess exposes the lateral container opening, is rotatable.
- Bone graft substitutes may be classified into so-called autografts (bone graft made from the patient's own bone material), allografts (bone graft made from non-patient human bone, eg from a bone bank), xenografts (made from biological material of non-human origin) and synthetic bone graft substitutes (eg on the basis of hydroxyapatite, often with the addition of growth factors and endogenous substances).
- autografts bone graft made from the patient's own bone material
- allografts bone graft made from non-patient human bone, eg from a bone bank
- xenografts made from biological material of non-human origin
- synthetic bone graft substitutes eg on the basis of hydroxyapatite, often with the addition of growth factors and endogenous substances.
- the bone substitute material is in the form of a poorly fluid mass.
- This usually consists of a particulate or granular solid phase (eg milled or otherwise comminuted solid bone components and / or powdered synthetic materials such as hydroxyapatite, tricalcium phosphate, calcium sulfate or bioglass) and a liquid phase (eg, autologous blood, blood plasma, bone marrow aspirate, etc.).
- a particulate or granular solid phase eg milled or otherwise comminuted solid bone components and / or powdered synthetic materials such as hydroxyapatite, tricalcium phosphate, calcium sulfate or bioglass
- a liquid phase eg, autologous blood, blood plasma, bone marrow aspirate, etc.
- Such mass is often reminiscent in its consistency of wet sand.
- larger particles such as bone fragments may occur in the mass. When compressed such a mass tends to caking and loses its fluidity almost completely.
- US 8,034,034 B2 discloses a syringe with a lateral opening. Injectable material such as bone cement can be filled through the opening in the syringe. After filling, the opening is closed by a lid.
- a lid can slide over the opening, or it can be pivoted onto the opening upon actuation of the syringe plunger. It is also disclosed to close the opening independently of an actuation of the syringe plunger.
- a syringe is only badly suitable for delivering bone replacement materials with a strong particle-containing consistency. In practice, the back pressure through the bone substitute material can be so large that a discharge of the material is completely impossible.
- US 6,582,438 discloses a discharge device having two concentric cylinders with elongate openings in their side walls and a piston.
- the cylinders are rotated against each other so that their openings come to lie one above the other.
- the bone substitute material is then filled in laterally.
- the outer cylinder is rotated so that it closes with its side wall, the opening of the underlying inner cylinder.
- the bone substitute material is discharged by pushing the piston through the inner cylinder.
- a discharge device for discharging a mass which comprises:
- a housing having a circumferential housing wall, an open proximal housing end and an open distal housing end, wherein a lateral recess is formed in the housing wall;
- a container insert arranged in the housing with a circumferential container wall, with an open proximal container end and a distal container end, wherein a lateral container opening is formed in the container wall, and wherein the container insert relative to the housing between a closure position, in which the housing wall closes the lateral container opening, and a release position in which the lateral recess releases the lateral container opening, is rotatable about a longitudinal axis.
- the lateral container opening extends axially through to the distal container end, without a region of the container wall adjoining the lateral container opening along the longitudinal axis in the distal direction.
- the cavity defined by the container and the housing as a whole has a cross-section which does not diminish anywhere, at least between the proximal end of the container opening and the distal container end.
- the rotatable in the housing arranged container insert defines a central longitudinal axis, which coincides with the axis of rotation of the twisting movement.
- the distal direction is the direction in which the mass is advanced along the central longitudinal axis toward the housing outlet opening to discharge it.
- the proximal direction indicates the corresponding opposite direction to it.
- the lateral direction denotes a radial direction with respect to the longitudinal axis.
- a discharge device for discharging a mass which comprises:
- a housing having a circumferential housing wall, an open proximal housing end and an open distal housing end, wherein a lateral recess is formed in the housing wall;
- the housing wall has a wall thickness (measured in the radial direction), which decreases continuously in the circumferential direction over an angular range of at least 10 ° relative to the lateral recess.
- the decrease of the radial wall thickness preferably takes place only on the outside of the housing wall (i.e., on the outer casing surface). It preferably takes place in such a way that the housing wall forms a blade-like scraping edge at the boundary to the lateral recess.
- the outer casing surface and the inner outer casing surface run towards the Abstreifkante at an acute angle, oryak at an angle of at least 5 ° and at most 60 °, more preferably at least 10 ° and at most 45 ° to each other.
- the wiper edge may be rounded to minimize the risk of injury.
- the angular range over which the wall thickness decreases is preferably at least 20 °, more preferably at least 30 ° in the circumferential direction.
- a gradual, continuous decrease in the radial wall thickness to the lateral recess or to the wiping edge ensures that the housing wall curves away from the wiping edge to such an extent that the normal vector on the outer housing lateral surface adjacent to the wiping edge nowhere has a directional component that in Direction of a centrally extending through the lateral recess radial plane. In this way, when filling an undesirable funnel effect, which would make it difficult to strip the excess mass avoided.
- the lateral opening preferably has two mutually parallel and parallel to the longitudinal axis extending boundaries.
- the wiper edge in this case runs parallel to the longitudinal axis.
- the container wall can also have a decreasing radial wall thickness in the circumferential direction towards the lateral container opening, ie it can taper in the circumferential direction towards the lateral container opening.
- the decrease takes place Wall thickness of the container wall only on the inside, ie on the inner container surface area.
- the container wall thereby forms, adjacent to the housing wall, a blade-like shearing edge, adjoined by an anchoring surface, which is formed by a part of the inner container lateral surface.
- the outer container casing surface and the inner container casing surface run towards the shearing edge at an acute angle, preferably at an angle of at least 5 ° and at most 60 °, more preferably at least 10 ° and at most 45 ° towards each other.
- the scraping edge and the shearing edge preferably adjoin one another in the release position, ie together they form a type of blade over which the mass to be filled can be scraped off.
- a discharge device for discharging a mass which comprises:
- a housing having a circumferential housing wall, an open proximal housing end and an open distal housing end, wherein a lateral recess is formed in the housing wall;
- the container insert has a free container cross-section which increases continuously along the longitudinal axis over an axial region in the distal direction and preferably linear.
- the continuous increase in the free container cross-section is preferably carried out by an amount which is calculated as follows:
- the inner diameter per unit length increases by at least 0.5 per thousand, ie per centimeter length of the container, the inner diameter increases by at least 5 microns , Preferably, the increase is at least 2 parts per thousand.
- the increase is preferably at most 30 parts per thousand, that is, the per centimeter length of the container, the inner diameter increases by at most 0.3 millimeters.
- one size (D) per unit length increases by at least 0.5 parts per thousand, preferably at least 2 parts per thousand, and at most 30 parts per thousand, whereby the size (D) denotes a mean diameter and is defined as follows :
- A denotes the free cross-sectional area of the container.
- the axial region over which the free container cross section increases preferably extends over a substantial portion of the length of the container. Specifically, it is preferred if this axial region extends continuously from the proximal end of the container opening to the distal container end, ie if the gradual increase over the entire length of the container opening takes place. But it may be sufficient if the gradual increase over a part of this length takes place, e.g. over the distal 50% of the length of the container opening.
- the container opening has a length of 130 mm
- the average diameter (D) continuously increases by about 0.1 to 3 mm over this length.
- the increase is preferably about 0.1 mm to 0.5 mm, more preferably about 0.3 mm, based on a length of 130 mm.
- the increase is preferably about 0.5 mm to 3 mm, more preferably about 1 mm, based on a length of 130 mm. All three aspects of the invention may be implemented independently or combined with each other as desired. The following considerations apply to all three aspects of the invention.
- the outside of the container wall is preferably located on the inside of the housing wall and slides during rotation of the container insert on the inside of the housing wall.
- the housing wall is preferably in the region of the lateral recess on the inside of a cylindrical shape
- the container wall is preferably in the region of the lateral container opening on the outside of a corresponding cylindrical shape. But there are also other rotationally symmetric shapes possible.
- the discharge device further comprises a piston which is displaceable in the container insert along the longitudinal axis.
- a piston can also be provided by an external squeezing device and therefore does not necessarily belong to the actual dispensing device.
- the piston preferably does not cooperate sealingly with the container wall. It is preferably not made of an elastomer, but made of a relatively hard material that does not produce a sealing effect with the container wall. But it is also conceivable that the piston has a soft material, in particular an elastomer, and / or that the piston is slotted.
- the piston may be slotted so as to have the ability to expand radially.
- the piston may have a slot or a plurality of slots which extend parallel or obliquely to the longitudinal axis partly through the piston. The slots preferably form incisions which are open in the distal direction.
- the piston has two open slots in the distal direction, which extend in the radial direction completely through the piston and intersect, in particular in a radial plane perpendicular to each other.
- Through the slots of the piston is divided into several segments which are radially resiliently connected to the push rod. Upon exposure to a Compression force from outside give these segments radially inward and thus reduce the outer circumference of the piston. When the compression force decreases, the segments spring back outward.
- a piston with one or more such slots thus has the ability to expand radially or be radially compressed.
- Such a radial expansion capability may be desirable, for example, in the case of a continuous increase in the free container cross-section or the inner container diameter along the distal direction, since then the piston should have a smaller radial extent in the region of a smaller inner container diameter than in a region of a larger inner one container diameter.
- a piston of soft material would increasingly expand with increasing inner diameter of the vessel, and a piston with slits would increasingly spread as the inner vessel diameter increased.
- the piston may be connected to a pushrod to form a plunger.
- the piston protrudes radially slightly beyond the push rod, ie if the piston defines a piston diameter, the push rod defines a rod diameter, and the piston diameter is greater than the rod diameter. This prevents material such as e.g. Bone chips, which pass the piston in the area of the push rod, blocking the push rod.
- the piston diameter is preferably at least 0.2 mm larger than the rod diameter, in particular at least 0.5 mm larger. In terms of relative values, the rod diameter is preferably at most 95% of the piston diameter.
- the housing, the container insert, the piston and / or the push rod are preferably at least partially made of plastic. Many plastics are largely transparent to X-rays.
- the housing, the container insert, the piston and / or the push rod can have at least one radiopaque functional element. This can in particular at the distal end of the housing, at the distal end of the container and / or at the distal Be arranged at the end of the piston.
- a functional element can be embedded in the housing, the container insert, the piston and / or the push rod. It may be an element of a metal or of a strong X-ray absorbing plastic or composite material.
- the functional element may be annularly mounted around the distal end of the housing, the distal end of the container or the piston.
- a deflector may be formed, which adjoins the distal end of the container in the distal direction and is curved along the distal direction to the central longitudinal axis. Such a curved deflector allows a targeted discharge of the mass to be discharged to one side.
- a radially projecting handle e.g. in the form of two retaining wings, be formed at the proximal end of the housing and a radially projecting rotary handle at the open proximal end of the container.
- At least one container rotational stop can be formed on the container insert, and at least one housing rotary stop can be formed on the housing, wherein the container rotational stop is formed in the opposite direction to the housing rotational stop, and wherein upon rotation of the container insert in the housing in the direction of the release position and / or with an opposite rotation in the direction of the closed position The container rotation stop and the housing rotation stop abut each other.
- the container rotational stop is designed as a cam or web on the outer circumference of the container insert
- the housing rotational stop is designed as a complementary cam or web on the inner circumference of the housing.
- the plunger rod may have a plunger stop in the region of the distal plunger end, and the open proximal container end may have a container stop complementary thereto, wherein when the plunger is displaced along the proximal direction, the plunger stop strikes the container stop such that complete removal of the plunger from the plunger stop Container insert is obstructed.
- the plunger stopper is designed as an annular bead around the push rod around, and the container stopper is designed as an inwardly directed detent or as an inner bead on the inner circumference of the container.
- the container insert may be pre-filled with the mass and a removable closure may close the housing outlet.
- a first possible method for providing a mass to be discharged, in particular a bone replacement material, in a discharge device of the type described above comprises the following steps: i) turning the container insert relative to the housing about the longitudinal axis so that the lateral recess releases the lateral container opening; ii) filling the discharged mass through the lateral recess and the lateral container opening into the container insert; and iii) rotating the container insert relative to the housing about the longitudinal axis such that the housing wall closes the lateral container opening.
- the container insert is prefilled with a first component of the mass, and the housing outlet opening is closed by a closure.
- the method then includes the steps of: i) rotating the container liner relative to the housing about the longitudinal axis so that the lateral recess releases the lateral container opening; ii) adding a second, preferably liquid component of the mass through the lateral recess and the lateral container opening to the first component; iii) rotating the container liner relative to the housing about the longitudinal axis such that the housing wall closes the lateral container opening; and iv) removing the closure.
- WO 2013/063706 discloses a dispensing device in the manner of a pistol dispenser with an adapter, wherein the Adapter is formed a fastening structure for attaching a container with mass to be discharged.
- the dispensing device proposed here can be readily used with a squeezing device of the type disclosed in WO 2013/063706.

- FIGs 1-20 a first embodiment of a discharge device for discharging a poorly fluid mass, e.g. a bone substitute material, illustrated.
- the discharge device 1, a housing 200, a container insert 300 and a plunger 400.
- the housing 200 is shown separately in FIGS. 2-4. It has a circumferential housing wall (shell wall) 204 which defines a housing interior 212 and defines a proximal housing inlet opening 213 and a distal housing outlet opening 203.
- the housing 200 has, in the region of the proximal housing end 201, a widened region on which a handle 214 in the form of two retaining wings is formed.
- a cylindrical region which extends as far as the distal end of the housing 203, adjoins the proximal flared region in the distal direction.
- an elongate lateral recess 205 i.e., a window
- the housing wall 204 defines an inner casing surface 207 and an outer casing surface 208.
- the inner casing surface 207 and the outer casing surface 208 close in this area in a sectional plane perpendicular to the circumferential direction at an acute angle to each other and meet at a wiper edge 209. The function of this wiper edge will be explained in more detail below in connection with FIG.
- the container insert 300 is shown separately in FIGS. 5-7. It has a container wall 304, an open proximal container end 301 and an open distal container end 302.
- the container wall 304 has proximally a widened area, followed by a slender cylindrical area.
- a lateral container opening 303 is formed in the container wall 304.
- the lateral container opening 303 extends continuously parallel to the longitudinal axis L to the distal container end 302, without a region of the container wall 304 adjoining the lateral container opening 303 along the longitudinal axis L in the distal direction.
- the container wall 304 defines an inner container casing surface 305 and an outer container casing surface 306. On both sides of the lateral container opening, these casing surfaces are each connected by a shearing surface 310, wherein each of these shearing surfaces can be regarded as a part of the inner container casing surface 305 which is beveled with respect to the circumferential direction.
- the shearing surfaces 310 and the outer container lateral surface 306 meet at a respective shearing edge 307.
- the container wall 304 thus tapers in the circumferential direction towards the lateral container opening 303 in such a way that it forms a blade-like shearing edge 307 in each case.
- the respective shearing surface 310 (as part of the inner container lateral surface 305) and the outer container lateral surface 306 form an acute angle to each other in a sectional plane perpendicular to the circumferential direction.
- the shearing surfaces 310 and shearing edges 307 are explained in more detail below in connection with FIG. 11.
- the cavity bounded by the inner container lateral surface 306 has a free cross section which widens very slightly in the distal direction, as will be explained in more detail in connection with FIGS. 28 to 38.
- a radially projecting rotary handle 308 is formed at the proximal end of the container 301, which facilitates rotation of the container insert 300 in the housing 200.
- the plunger 400 is shown in FIG. 8 alone.
- the plunger 400 has at its distal end 402 a piston 405, to which a plunger rod 403 adjoins proximally.
- the piston 405 protrudes radially slightly beyond the push rod 403, ie it has a piston diameter which is greater than the plunger diameter of the push rod 403.
- the push rod 403 is connected via a connecting piece 406 to a pressure plate 407.
- the pressure plate 407 in this embodiment is a disk-shaped thumb rest, on which a user can exert manual pressure for the discharge of the mass from the discharge device 1.
- the push rod 403 has a plunger stop in the form of an annular bead 404 surrounding the push rod 403, whose function will be explained in more detail in connection with FIG. 27.
- FIGS. 9-12 show the discharge device in a release position (filling position).
- the container insert 300 was inserted through the proximal housing end 201 into the housing interior 212 until the rotary handle 308 of the container insert 300 rests on the proximal housing end 201, and the plunger 400 was inserted with its distal ram end 402 into the open proximal container end 301 of the container insert 300.
- the lateral container opening 303 of the container wall 304 is located directly below the lateral recess 205 of the housing wall 204, so that the lateral container opening 303 together with the lateral recess 205 define a common filling opening 206 of the discharge device 1.
- the mass is then filled by a user into this filling opening 206, that is through the lateral recess 205 of the housing 200 and the lateral container opening 303 of the container insert 300 into the interior of the container insert 300.
- This can be done by hand and / or with the aid of a tool, for example a spatula.
- the outer container jacket surface 306 of the container wall 304 is in contact with the inner housing shell surface 207 of the housing wall 204, and that in the release position the shear edges 307 of the container insert are arranged immediately adjacent to the scraping edges 209 of the housing.
- a mass for example a Bone graft material, along a transverse to the longitudinal axis L extending stripping over the lateral recess 205 of the housing 200 are deleted.
- the scraper edge 209 serves as a filling aid and allows easier stripping of the mass.
- the mass is sheared off towards the inside by the shearing edge 307 and thus reaches the interior of the container insert 300.
- the wall thickness of the housing wall 204 towards the lateral recess 205 decreases continuously on the outside in the circumferential direction over an angular range ⁇ in order to form the scraping edge 209.
- This angular range ⁇ is about 35 ° here.
- the continuous decrease in the wall thickness towards the lateral recess 205 over a relatively large angular range ensures that the outer casing surface 208 continuously curves outward with respect to the circumferential direction from the scraping edge 209 without a normal vector N on the outer casing surface 208 Direction component which extends in the direction of a centrally through the lateral recess 205 extending radial plane P. This avoids a funnel effect.
- the radial plane P in the present case represents a plane of symmetry of the housing 200, and the housing 200 is formed mirror-symmetrically with respect to this radial plane P.
- the cam 309 In the release position, the cam 309 abuts the cam 215 in the circumferential direction and thereby prevents further rotation of the container insert 300 in the housing 200 in the counterclockwise direction.
- Figures 13-16 illustrate an intermediate position of the discharge device, which lies between the release position and the closed position.
- the discharge device 1 was first filled in its release position with the mass, and the container insert 300 was then rotated in the housing 200 so far about the longitudinal axis L that the scraping edge 209 on one side of the lateral recess of the housing with the shearing edge 307 on the opposite side of the lateral container opening is in contact.
- This causes the oblique to the circumferential direction extending shearing surface 310 at the shearing edge 307, that parts of the mass, which are still in the region of the scraping edge 209, sheared off by the shearing edge 307 and displaced in the direction of the interior of the container insert.
- This shearing action reduces the risk of jamming, for example, of bone splinters between the container wall 304 and the housing wall 204.
- FIGS. 17-20 illustrate the closing position of the discharge device.
- the container insert 300 has been further rotated, starting from the intermediate position, so that the container opening 303 of the container insert 300 is now located on an opposite side of the lateral recess 205 of the housing 200 and is thereby completely covered by the housing wall 204.
- the discharge device 1 is ready for discharging.
- FIG. 20 illustrates how, in this position, the cam 309 'acting as a container rotational stop abuts in the circumferential direction against the cam 215 acting as a housing rotational stop and thus prevents further rotation of the container insert 200 in the clockwise direction beyond the closing position.
- FIG. 21 shows a discharge device according to a second embodiment.
- This second embodiment largely corresponds to the first embodiment, but has a removable closure 217 in the form of a closure cap.
- the closure cap 217 is designed here as a screw cap. It closes the housing outlet opening 203 by an internal thread, which is formed on an inner side of the closure cap, with a corresponding external thread which is formed on the outer casing surface 208 at the distal end of the housing 202 in threaded engagement.
- This embodiment is particularly advantageous when the container insert 300 with a component of the mass to be discharged (for example, a powder) was pre-filled inserted into the housing 200.
- a component of the mass to be discharged for example, a powder
- a user grips the rotary handle 308 of the container insert 300 and rotated so that the discharge device comes into the release position.
- the user can now fill in the second component (eg, wet the powder) and transfer the discharge device 1 by turning the container insert 300 in the housing 200 again into the closing position.
- the closure cap 217 By removing the closure cap 217, the housing outlet opening 203 is then released, so that the mass thus provided can be discharged by advancing the plunger 400.
- Figures 23 to 26 show a third and a fourth embodiment of a discharge device. These in turn largely correspond to the first embodiment, however, wherein the distal end of the housing 202 is formed differently.
- the distal end of the housing extends obliquely to the longitudinal axis L.
- a deflector 211 adjoins the distal end of the housing, which deflector is distally along the distal direction to the central longitudinal axis L is curved. This export form makes it easier to discharge the mass to one side.
- FIG. 27 shows a detailed view of the region J of FIG. 26, wherein the plunger 400 abuts with its plunger stopper 404 in the form of an annular bead on a container stop 311 in the form of a latching nose in the open proximal container end 301 such that displacement of the plunger 400 along the proximal direction is prevented by the proximal housing end 201 from the container insert 300 out. As a result, falling out of the plunger 400 from the discharge device can be prevented.
- FIGS. 28 and 29 illustrate the piston 400 according to the first embodiment, wherein now in particular the properties of the piston 405 protruding radially over the push rod 403 are to be clarified.
- the piston 405 defines a piston diameter, while the push rod 403 defines a smaller rod diameter. The transition between piston and push rod via a conical ramp.
- Figures 30 to 33 illustrate a discharge device 1 according to the first embodiment, the container insert 300 is inside in the distal direction continuously expanding.
- Both the outer container lateral surface 306 and the push rod 403 have a cylindrical shape, each with a constant diameter, while the inner container lateral surface 305 defines an inner container diameter, which increases continuously along the longitudinal axis L in the distal direction.
- the radial spacing of the push rod 403 from the inner container jacket surface 305 becomes increasingly greater.
- FIG. 30 shows the discharge device 1 with the plunger 400 received therein, whose distal plunger end 402 is located in the region of the proximal end 302 of the container.
- FIG. 31 shows a detailed view of the region L of FIG. 30, from which it can be seen that the outer circumferential surface of the piston 405 is in direct proximity to the inner container lateral surface 305, but a narrow gap is formed therebetween. This is followed in the proximal direction by a larger gap between the outer lateral surface of the push rod 403 and the inner container lateral surface 305.
- FIG. 34-38 A fifth embodiment of the invention is illustrated in Figures 34-38.
- This embodiment corresponds to the first embodiment; however, the plunger 400 'at its distal end of the plunger has a piston 405' with two intersecting slots (Cuts), wherein the slots extend radially through the piston 405 'and are open in the distal direction.
- These slots are perpendicular to each other and divide the piston into four equal segments. These segments can deflect radially inwards, in the direction of the longitudinal axis, when a radial force acts on them. This allows the piston 405 'to radially expand or radially compress along the radial direction as it passes through a container of variable free cross-section.
- FIGS. 35 to 38 illustrate the use of this plunger 400 'in a discharge device 1, the container insert 300 of which widens continuously conically on the inside in the distal direction.
- the slotted piston 405 ' has in the proximal region of the container insert 300, with a smaller inner container diameter, a smaller radial extent and a smaller circumference than in the distal region with a larger inner container diameter, since with increasing inner container diameter, the segments of the piston 405' increasing sprungly spread.
- the slotted piston 405 ensures that the mass to be discharged can nevertheless be discharged efficiently and completely, even if the container insert 300 widens relatively distally.
- Discharge device 303 lateral container opening
- Housing 305 inner container lateral surface proximal housing end 306 outer container lateral surface distal housing end 307 shearing edge
- Container insert L longitudinal axis
