## Abstract

A surgical instrument for use in a sinus lift includes a substantially cylindrical sleeve which is sealingly insertable into a bore of a jawbone. The sleeve has a lumen and is formed with an inlet channel and an outlet port which is in fluid communication with the lumen. A vibration unit is operatively connected to the instrument for transmitting vibrations into the lumen.

## Claims

### Claim 1

A surgical instrument for detaching a sinus membrane from a jawbone during a sinus lift, comprising:
a substantially cylindrical sleeve having a dull distal tip, said sleeve sealingly insertable into a predrilled bore of the jawbone, said sleeve having a not more than one lumen, the not more than one lumen extending entirely along the sleeve from a proximal end of the sleeve to the distal tip of the sleeve, said not more than one lumen containing a fluid under pressure; and
a vibration unit operatively connected to the sleeve to cause vibrations of the fluid in the lumen and transmission of the vibrations to an area outside the lumen to promote in the area outside of the lumen an elevation of the sinus membrane from the jawbone.

### Claim 2 (depends on 1)

The surgical instrument of claim 1, for use in a crestal sinus lift.

### Claim 3 (depends on 1)

The surgical instrument of claim 1, wherein the lumen has an inlet channel which is in fluid communication with a feed conduit for the fluid.

### Claim 4 (depends on 1)

The surgical instrument of claim 1, wherein the vibration unit has an ultrasonic transducer.

### Claim 5 (depends on 4)

The surgical instrument of claim 4, wherein the ultrasonic transducer is detachably fixed to the sleeve.

### Claim 6 (depends on 5)

The surgical instrument of claim 5, wherein the sleeve has contact points for effecting a detachable connection of the ultrasonic transducer to the sleeve.

### Claim 7 (depends on 4)

The surgical instrument of claim 4, wherein the ultrasonic transducer is permanently fixed to the sleeve.

### Claim 8 (depends on 1)

The surgical instrument of claim 1, further comprising a flange attached to the sleeve to limit a penetration depth of the sleeve into the bore of the jawbone.

### Claim 9 (depends on 8)

The surgical instrument of claim 8, wherein the flange is movably attached to the sleeve for securement of the flange at different heights.

### Claim 10 (depends on 1)

The surgical instrument of claim 1, further comprising a sealing element attached to the sleeve.

### Claim 11 (depends on 10)

The surgical instrument of claim 10, wherein the sealing element is a latex hose placed over the sleeve.

### Claim 12 (depends on 1)

The surgical instrument of claim 1, wherein the vibration unit is received within the sleeve and operatively connected with the lumen.

### Claim 13 (depends on 1)

The surgical instrument of claim 1, further comprising a handle connected to the sleeve for manipulating the surgical instrument.

### Claim 14 (depends on 1)

The surgical instrument of claim 1, further comprising a pressure control device for limiting a pressure buildup in the lumen.

### Claim 15 (depends on 1)

The surgical instrument of claim 1, wherein the fluid is a physiological saline solution.

### Claim 16 (depends on 1)

The surgical instrument of claim 1, further comprising a pressure application unit for introducing the fluid into the sleeve at a pressure sufficient to elevate the sinus membrane from the jawbone in conjunction with the vibrations generated by the vibration unit.

### Claim 17 (depends on 16)

The surgical instrument of claim 16, wherein the pressure-application unit is a syringe.
