Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
51 words
A surgical handpiece, comprising: a) an outer shell; b) a pumping section having a micropump, the pumping section held within the outer shell by seals so as to allow the micropump to aspirate fluid from a surgical site; and c) an ultrasonic transducer section held within the outer shell by seals.
Claim 2
Dependent Claim
51 words
A surgical handpiece, comprising: a) an outer shell; b) a pumping section having a micropump, the pumping section held within the outer shell by seals so as to allow the micropump to aspirate fluid from a surgical site; and c) an ultrasonic transducer section held within the outer shell by seals.
Claim 3
Dependent Claim
29 words
The device of claim 1 , further comprising a sensor section held within the outer shell and separated from the pumping section and the transducer section by an isolator.
Claim 4
Dependent Claim
14 words
The device of claim 1 , wherein the micropump is a micromachined peristaltic pump.
Claim 5
Dependent Claim
13 words
The device of claim 1 , wherein the micropump is an ultrasonic pump.
Claim 6
Dependent Claim
14 words
The device of claim 2 , wherein the micropump is a micromachined peristaltic pump.

Claim 10
Dependent Claim
13 words
The device of claim 7 , wherein the micropump is an ultrasonic pump.
Claim 11
Dependent Claim
14 words
The device of claim 7 , wherein the micropump is a micromachined peristaltic pump.
Claim 12
Dependent Claim
13 words
The device of claim 8 , wherein the micropump is an ultrasonic pump.
Claim 13
Dependent Claim
14 words
The device of claim 8 , wherein the micropump is a micromachined peristaltic pump.
Claim 14
Dependent Claim
24 words
The device of claim 1 , wherein the micropump is an ultrasonic pump having an external pump horn and a removable internal pump horn.
Claim 15
Dependent Claim
38 words
The device of claim 13 , wherein the removable internal pump horn is held within the external pump horn by a rear seal, and a nodal point of the internal pump horn is located at the rear seal.
Claim 16
Dependent Claim
53 words
A surgical handpiece, comprising: a) an outer shell; b) a pumping section held within the outer shell by seals and having a ultrasonic pump, the ultrasonic pump having a pumping chamber formed between an external pump horn and an internal pump horn, wherein vibration of the internal pump horn creates a pumping action.
Claim 17
Dependent Claim
53 words
A surgical handpiece, comprising: a) an outer shell; b) a pumping section held within the outer shell by seals and having a ultrasonic pump, the ultrasonic pump having a pumping chamber formed between an external pump horn and an internal pump horn, wherein vibration of the internal pump horn creates a pumping action.
Claim 18
Dependent Claim
21 words

Claim 19
Dependent Claim
52 words
A surgical handpiece, comprising: a) an outer shell; and b) a pumping section having a peristaltic micropump, the pumping section held within the outer shell by seals so as allow the micropump to aspirate fluid from a surgical site, wherein the peristaltic pump is formed by a channel covered by a membrane.
Claim 20
Dependent Claim
52 words
A surgical handpiece, comprising: a) an outer shell; and b) a pumping section having a peristaltic micropump, the pumping section held within the outer shell by seals so as allow the micropump to aspirate fluid from a surgical site, wherein the peristaltic pump is formed by a channel covered by a membrane.
Claim 21
Dependent Claim
21 words
