Abstract

A surgical tool comprising an elongate moulded plastic handle (2) and a tool member (7) having a tip portion (43), the handle (2) defining an elongate sl ot (11,20,34) which is configured to receive and mount the tool member (7) therein, and having an aperture (5) at one end (6) such that the tip portion (43) of the tool member (7) received in the slot (11,20,34) protrudes from t he handle (2) through the aperture (5).

Claims (23)

1. A surgical tool comprising an elongate moulded handle having a body portion and a base portion and a substantially planar elongate tool member having a tip portion, the body and base portions being fixed relative to each other to form the handle when the tool is assembled, the handle defining an elongate slot formed from corresponding channels in the body and base portions, each channel being configured to receive an edge of the tool member such that the tool member it lies in a plane substantially at right angles to a plane along which the body portion and the base portion are fixed relative to each other.
2. A surgical tool according, to claim 1 wherein an actuator for controlling the tool member is mounted in an elongate aperture in the handle.
3. A surgical tool according to claim 2 wherein the actuator comprises a lever having a first end immovably mounted in the aperture in the body portion and a second end deflectable with respect to the first end and the body portion into the handle toward the base portion when pressure is applied to said second end.
4. A surgical tool according to claim 3 wherein a bridge divides the aperture in the body portion into two separate openings and a region of the lever between the first and second ends extends over the bridge.
5. A surgical tool according to claim 4 wherein said first end of the lever includes, an elongate connecting member thereon dimensioned to be a snug fit in one opening between the body portion and the bridge to mount the lever to the body portion such that the region of the lever extending over the bridge deforms in response to the application of pressure to the second end of the lever.
6. A surgical tool according to claim 5 wherein the connecting member is longer than the length of the opening and a cut-out is formed in the underside of the body portion extending from, the opening to, receive the portion of the member that extends beyond the opening.
7. A surgical tool according to any of claims 3 to 6 wherein the upper surface of the lever is contoured to lie flush with the surface of the body portion.
8. A surgical tool according to any preceding claim, wherein the tool member comprises forceps or tweezers having two opposable arms extending from an integral hub to the tip portion at the remote end of each arm, said arms being resiliently deformable to bring the tip portion on each arm into contact.
9. A surgical tool according to claim 8 wherein one arm is received and mounted in the channel in the base portion and the other arm is received and mounted in the channel in the body portion with the tip portion of said arms protruding from the handle through the aperture.
10. A surgical tool according to claim 9 wherein an extension of the channel formed in the body portion is formed in the lever such that the arm received in the channel in the body portion is also received in the channel in the lever such that when pressure is applied to the second end of the lever, the arm retained in the channel in the lever is urged towards the other arm to bring the tip portions into contact, the resilience of the arm and of the lever urging it back to its original position when the pressure is released.
11. A surgical tool according to any preceding claim, wherein the aperture through which the tool tip protrudes is formed in the base portion, said channel in the slot in the base portion terminating at the aperture.
12. A surgical tool according to claim 11, wherein the base portion includes an integrally formed upstanding nose section defining the end of the handle in which the aperture is formed.
13. A surgical tool according to claim 12 wherein an end of the body portion includes a recess to receive the nose section of the base portion.
14. A surgical tool according to any preceding claim, including co-operating means to attach the body portion to the base portion.
15. A surgical tool according to claim 14 wherein the cooperating means comprises a pair of elongate rails depending from the length of the body portion for engagement with corresponding recesses in the base portion.
16. A surgical tool according to any preceding claim, wherein the tool member is unitary metal component formed from a flat sheet by, stamping, punching, laser cutting, water cutting, wire erosion or machining.
17. A surgical tool according to any preceding claim, wherein the handle is contoured to enable it to be held in a pen-like grip between the thumb and forefinger and enable precise fingertip control.
18. A surgical tool according to any preceding claim, wherein the handle defines a cavity therein and a frangible wall section to prevent the tool member from sliding into the cavity.
19. A surgical tool according to claim 18 wherein the frangible wall is configured such that when force is applied to the tool member in a longitudinal direction toward the handle, the frangible wall breaks to allow the tool member to retract into the cavity.
20. A surgical tool according to claim 17 wherein the base portion or the body portion is coloured to signify the type of tool member contained in the handle.
21. A surgical tool according to any preceding claim, wherein the tool can be sterilised for re-use.
22. A surgical tool according to any preceding claim, wherein the moulded handle is formed from a plastics material.
23. A surgical tool substantially as hereinbefore described with reference to the accompanying drawings.

1. A surgical tool comprising an elongate moulded handle having a body portion and a base portion and a substantially planar elongate tool member having a tip portion, the body and base portions being fixed relative to each other to form the handle when the tool is assembled, the handle defining an elongate slot formed from corresponding channels in the body and base portions, each channel being configured to receive an edge of the tool member such that the tool member it lies in a plane substantially at right angles to a plane along which the body portion and the base portion are fixed relative to each other.

2. A surgical tool according to claim 1 wherein an actuator for controlling the tool member is mounted in an elongate aperture in the handle.

3. A surgical tool according to claim 2 wherein the actuator comprises a lever having a first end immovably mounted in the aperture in the body portion and a second end deflectable with respect to the first end and the body portion into the handle toward the base portion when pressure is applied to said second end.

4. A surgical tool according to claim 3 wherein a bridge divides the aperture in the body portion into two separate openings and a region of the lever between the first and second ends extends over the bridge.

5. A surgical tool according to claim 4 wherein said first end of the lever includes an elongate connecting member thereon dimensioned to be a snug fit in one opening between the body portion and the bridge to mount the lever to the body portion such that the region of the lever extending over the bridge deforms in response to the application of pressure to the second end of the lever.

6. A surgical tool according to claim 5 wherein the connecting member is longer than the length of the opening and a cut-out is formed in the underside of the body portion extending from the opening to receive the portion of the member that extends beyond the opening.
