Abstract

Adapter assemblies are provided for selectively interconnecting a surgical end effector that is configured to perform at least a pair of functions and a surgical device that is configured to actuate the end effector, wherein the adapter assembly includes an adapter knob housing configured and adapted for connection with the surgical device and to be in operative communication with each of the at least one rotatable drive shaft of the surgical device, the adapter knob housing defining a lumen extending longitudinally therethrough and a ring gear formed in an inner surface of the lumen of the adapter knob housing, the ring gear defining an internal array of gear teeth which are engaged with a spur gear of a rotatable drive shaft. The adapter knob housing may be a unitary member and may be formed of plastic.

Claims

1. An adapter assembly for selectively interconnecting a surgical end effector that is configured to perform a function and a surgical device that is configured to actuate the end effector, the end effector including at least one axially translatable drive member, and the surgical device including at least one rotatable drive shaft, the adapter assembly comprising:

an adapter knob housing configured and adapted for connection with the surgical device and to be in operative communication with each of the at least one rotatable drive shaft of the surgical device, the adapter knob housing defining a lumen extending longitudinally therethrough;

an outer tube having a proximal end supported by the adapter knob housing and a distal end configured and adapted for connection with the end effector, wherein the distal end of the outer tube is in operative communication with each of the at least one axially translatable drive member of the end effector;

a drive transmitting assembly including;

a proximal rotatable drive shaft rotatably supported in the adapter knob housing and having a spur gear supported on a distal end thereof and a proximal end connectable to a rotatable drive shaft of the surgical device; and

a ring gear formed in an inner surface of the lumen of the adapter knob housing, the ring gear defining an internal array of gear teeth which are engaged with the spur gear of the proximal rotatable drive shaft;

wherein rotation of the rotatable drive shaft of the surgical device results in rotation of the proximal drive shaft, and wherein rotation of the proximal drive shaft results in rotation of adapter knob housing via the ring gear, and rotation of the distal coupling assembly to rotate the end effector.

2. The adapter assembly according to claim 1, wherein the adapter knob housing is a unitary member.

3. The adapter assembly according to claim 2, wherein the adapter knob housing is formed of plastic.

4. The adapter assembly according to claim 1, wherein adapter knob housing includes a distal housing half, and a proximal housing half secured to the distal housing half.

5. An electromechanical surgical system, comprising:

a hand-held surgical device, including a device housing defining a connecting portion for selectively connecting with an adapter assembly;

an end effector configured to perform at least one function, the end effector including at least one axially translatable drive member; and

an adapter assembly for selectively interconnecting the end effector and the surgical device, the adapter assembly including;

an adapter knob housing configured and adapted for connection with the surgical device and to be in operative communication with each of the at least one rotatable drive shaft of the surgical device, the adapter knob housing defining a lumen extending longitudinally therethrough;

an outer tube having a proximal end supported by the adapter knob housing and a distal end configured and adapted for connection with the end effector, wherein the distal end of the outer tube is in operative communication with each of the at least one axially translatable drive member of the end effector;

a drive transmitting assembly including;

a proximal rotatable drive shaft rotatably supported in the adapter knob housing and having a spur gear supported on a distal end thereof and a proximal end connectable to a rotatable drive shaft of the surgical device; and

a ring gear formed in an inner surface of the lumen of the adapter knob housing, the ring gear defining an internal array of gear teeth which are engaged with the spur gear of the proximal rotatable drive shaft;

wherein rotation of the rotatable drive shaft of the surgical device results in rotation of the proximal drive shaft, and wherein rotation of the proximal drive shaft results in rotation of adapter knob housing via the ring gear, and rotation of the distal coupling assembly to rotate the end effector.

6. The electromechanical surgical system according to claim 5, wherein the adapter knob housing is a unitary member.

7. The electromechanical surgical system according to claim 6, wherein the adapter knob housing is formed of plastic.

8. The electromechanical surgical system according to claim 5, wherein adapter knob housing includes a distal housing half, and a proximal housing half secured to the distal housing half.
