## Abstract

An assembly includes a bone marrow aspiration adaptor (10), which includes a distal interface member (12) and a proximal interface member (14), which extend in opposite directions from a body (16). A lumen (18) extends through the distal interface member (12) and the proximal interface member (14). The proximal interface member (14) includes a fluid connector (22). A seal (24) is disposed in the distal interface member (12) inside the lumen (18).

## Claims

### Claim 1

An assembly comprising:
a surgical tool adaptor comprising a distal interface member and a proximal interface member, which extend in opposite directions from a body, wherein a lumen extends through said distal interface member and said proximal interface member, said proximal interface member comprising a fluid connector; and
a seal disposed in said distal interface member inside said lumen, and wherein said lumen has a proximal portion, which extends distally from a proximal end of said proximal interface member to a conical opening, a distal end of said conical opening being larger in diameter than said proximal portion of said lumen, and said lumen has a distal portion, which extends proximally from a distal end of said distal interface member to said distal end of said conical opening, said distal portion of said lumen being larger in diameter than said distal end of said conical opening so as to form a shoulder at a junction of said distal portion of said lumen and said distal end of said conical opening, and wherein said surgical tool adaptor is coupled to a surgical tool assembly that comprises a shaft that passes distally through said distal interface member and said shaft comprises a screw connecting member which is distal to said distal interface member.

### Claim 2 (depends on 1)

The assembly according to claim 1, wherein a proximal end of said conical opening and said proximal portion of said lumen are equal in diameter.

### Claim 3 (depends on 1)

The assembly according to claim 1, wherein said shaft is sealed by said seal.

### Claim 4 (depends on 1)

The assembly according to claim 1, wherein said surgical tool assembly is formed with a lumen.

### Claim 5 (depends on 1)

The assembly according to claim 1, wherein said shaft is part of a cannulated screwdriver.

### Claim 6 (depends on 1)

The assembly according to claim 1, wherein said screw connecting member couples with a head of a pedicle screw.

### Claim 7 (depends on 1)

The assembly according to claim 1, wherein a proximal end of said shaft abuts against said shoulder.

### Claim 8 (depends on 1)

A method of bone marrow aspiration comprising using the assembly of claim 1 to aspirate bone marrow through said lumen of said surgical tool adaptor.
