Abstract

Apparatus is provided that includes a surgical tool for use with solid particles and a physiological liquid solution. The surgical tool includes (a) a shaft unit, which is shaped so as to define a delivery lumen, and a distal opening, which is disposed within 10 mm of a distal end of the shaft unit, in fluid communication with the delivery lumen; (b) a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; and (c) a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen.

a composition source, which is coupled in fluid communication with the delivery lumen, and which is configured to provide a solid-liquid composition of the solid particles and the physiological liquid solution; and

a pump, which is configured to pump the solid-liquid composition through the distal opening via the delivery lumen, at a pulsating hydraulic pressure that periodically varies between positive and negative.

2. The apparatus according to claim 1, wherein the distal opening is disposed within 5 mm of the distal end of the shaft unit.

3. The apparatus according to claim 2, wherein the distal opening is disposed at the distal end of the shaft unit.

4. The apparatus according to claim 1, wherein the composition source comprises a combining unit, which is configured to provide the solid-liquid composition by combining the solid particles with the physiological liquid solution.

5. The apparatus according to claim 4, wherein the combining unit comprises a mixing unit, which is configured to provide the solid-liquid composition by mixing the solid particles with the physiological liquid solution.

6. The apparatus according to claim 1, wherein the surgical tool further comprises a sealing element disposed around an external surface of the shaft unit, and configured to form a liquid-tight seal with tissue around and outside a bore through a bone when the shaft unit is inserted into the bore.

7. The apparatus according to claim 1, wherein the surgical tool further comprises a depth limiting element, which is configured to limit a depth of insertion of the shaft unit into a bore through a bone when the shaft unit is inserted into the bore.

8. The apparatus according to claim 1, wherein the surgical tool further comprises a solid-particle container, which contains the solid particles for combining with the physiological liquid solution.

9. The apparatus according to claim 1, wherein the solid particles are solid bone graft particles, and wherein the surgical tool is for use with the solid bone graft particles.

10. The apparatus according to claim 1, wherein the solid particles are selected from the group consisting of:

drug-releasing solid particles and solid drug particles, and wherein the surgical tool is for use with the selected solid particles.

11. The apparatus according to claim 1, wherein the surgical tool is configured as an oral surgical tool.

12. The apparatus according to claim 1, wherein the surgical tool is configured as a non-dental tool.

13. The apparatus according to claim 12, wherein the surgical tool is configured as an orthopedic tool.

14. A method comprising:

inserting, from a first side of a bone, a shaft unit of a surgical tool into a bore that passes through the bone from the first side to a second side of the bone, such that a distal opening disposed within 10 mm of a distal end of the shaft unit is disposed in the bore or in a cavity adjacent to the second side of the bone, wherein the distal opening is in fluid communication with a delivery lumen defined by the shaft unit;

providing a solid-liquid composition of (a) solid particles and (b) a physiological liquid solution from a solid-liquid composition source that is coupled in fluid communication with the delivery lumen; and

pumping the solid-liquid composition through the distal opening via the delivery lumen, at a pulsating hydraulic pressure that periodically varies between positive and negative.

15. The method according to claim 14, wherein the cavity is between the second side of the bone and a membrane.

16. The method according to claim 15, further comprising, before pumping the solid-liquid composition, raising the membrane to form the cavity between the second side of the bone and the membrane.
