A laparoscopic/thorascopic support device is described that engages and supports a body part in a non-traumatic manner while it is being acted upon by a surgical instrument. The support device is capable of lifting or otherwise moving a body part into a desired position to be operated upon or isolated from another body part. The support device includes an insertion device that punctures a covering of a body tissue to provide a passageway for access to the desired body part and a catheter. The catheter extends through the passageway and engages and temporarily supports the desired body part in a non-traumatic manner. The catheter (or manipulating device) includes a shaft made of a material that is sufficiently flexible to bend to a desired straight or curved orientation and is sufficiently rigid to maintain the desired orientation. According to the preferred embodiments of the invention, a distal end of the shaft bends about the desired body part to form a loop and secure the desired part within the loop. Preferably, the catheter also includes an eyelet on the shaft that retains the distal end of the shaft, and a first balloon located at the distal end that is directed through a central passage of the eyelet and is expanded to lock the catheter about the desired body part.

A game and method of playing it to simulate a minimally invasive surgical procedure. The game comprises, a base member over which a transparent domed cover having a pair of openings is located. The cover defines a work space thereunder. The base member includes a graphic likeness of a being, e. g. , a woman at the bottom of the work space. A plurality of anatomic parts shaped to simulate internal organs of the being are located in respective cavities at anatomically appropriate places on the graphic likeness. A lifting instrument simulating a conventional laparoscopic instrument is provided to be extended through one opening in the cover to grasp and lift the anatomic part out of its cavity without touching the cavity with the instrument, else a lamp on the base member is automatically illuminated and a buzzer sounds. An extraction instrument simulating another conventional laparoscopic instrument is provided to be extended through another opening in the cover to enable the lifted anatomic part to be transferred to the extraction instrument so that it can be taken out of the work space by the extraction instrument. Plural cards are provided to establish the surgical procedure to be attempted by each player.

A board game includes a board having a playing area to be filled by a plurality of playing pieces. Playing pieces of different geometric configurations are provided, with each geometric configuration being formed of a whole number multiple of a basic geometric shape. At least one indicating means is provided to identify each of the different geometric configurations. The indicating means is actuatable to randomly identify at least one geometric configuration of a playing piece to be placed on the playing area and/or removed from an opponent's playing area, with the geometric configuration being identified as a whole number multiple of the basic geometric shape. A number of embodiments of the above-described board game are part of the present invention as well as methods of playing the board games.

An electrosurgical instrument having a working end that utilizes a coagulation surface and a cutting surface that can be moved relative to each other and wherein only one of the two surfaces is electrically enabled depending on their relative positions. The user can then depress a switch to activate the electrically enabled surface.

Protective bandages in accordance with this invention include an anchoring strip having a protective layer on a lower surface thereof for overlying a desired area on a persons skin. Force-transmission-impeding means is provided on the side of the anchoring strip opposed to the side including the protective layer. The force-transmission-impeding means includes a top sheet adhered adjacent peripheral edges thereof to an upper surface of the anchoring strip to define an internal compartment between the anchoring strip and the top sheet. A compressive cushioning member is provided within the internal compartment for absorbing compressive forces, and low friction, relatively movable confronting surfaces are provided within the internal compartment spaced from the upper surface of the anchoring strip to absorb shear forces imposed upon the bandage. In certain embodiments of this invention, two pairs of low friction, relatively movable confronting surfaces are provided, whereas in another embodiment of this invention only one pair of low friction, relatively movable confronting surfaces is provided.

An articulated dissecting surgical tool includes an elongate member having a longitudinal axis and a dissecting tip located at a distal end of the elongate member. The tip includes a pair of opposed jaws and a coupling mechanism pivotally coupling the pair of opposed jaws together at a proximal end of the tip to permit pivotal movement of the opposed jaws relative to each other in a first plane between opened and closed positions. Each of the jaws includes a distal section having a forward and rear end, a proximal section having a forward and rear end, and an articulating pivot connection between the proximal and rear sections. The pivot connection is adjacent the rear end of the distal section and the forward end of the proximal section to permit angular movement of the distal section relative to the proximal section in a second plane different from the first plane to establish a desired angular relationship between the distal and proximal sections of each of the jaws. The rear ends of the proximal sections of the jaws constitute the proximal end of the tip at which the opposed jaws are pivotally coupled.

A surgical clamp has pivoting jaws with undulating arrays of teeth that are interdigitating and offset with relation to each other. This clamp structure assures a firm, non-slipping grip in the presence of blood and body fluids during surgery. The inner surfaces of the jaws are concave to allow the clamp to grasp more tissue or organ that would be possible with flat inner surfaces. Laparoscopic and open surgery embodiments are included. An alternative to the embodiment is a clamp having openings through which tissue or an organ can protrude to allow an even greater amount of tissue or organ to be grasped.

A hunting knife with a retaining member with dull sides located beneath the handle into which the blade can be retracted. This enables the knife to be handled safely, and to be placed in a holster without any sharp protruding edges which can damage the holster. Further, when the blade is extended, the dull sides of the retaining member do not damage animal organs or tissues away from the gutting area which makes it more efficient and easier to use. A keeper mechanism firmly locks the blade in its extended or retracted positions.

A unitary tissue hook for permanently joining tissue segments together includes a base section and at least one pair of spaced apart arms. A first end of each of the arms is joined to the base section and a second end of each of the arms is provided with a tip. The tips of at least one pair of arms face each other for receiving and holding the tissue segments together. In a preferred form of the invention, the base section includes two pairs of spaced apart arms, with the arms in each pair being spaced apart in a first direction from each other and with each pair of arms being spaced from the other pair in a second direction that is transverse to said first direction. The preferred embodiments of the invention are non-deformable.

A fishing creel which has individual compartments for fish which can be seen through see-through netting is disclosed. Each compartment has a one-way door for easy insertion of the fish. The compartments at the other end are blocked by a sliding panel, or alternatively by an end flap, which can be easily removed to allow access to the fish. The creel can be carried through the use of a shoulder strap or through use of belt loops.
