Definitions
- the invention relates in general to the field of surgical stapling of body tissue by means of surgical staplers and in particular to an indicator device for indicating features of surgical staples corresponding to an adjustable staple height!
- Known surgical staplers comprise an insertion shaft, a handle portion fitted to a distal end of the insertion shaft and a tissue manipulation portion fitted to a proximal end of the insertion shaft.
- the tissue manipulation portion holds a cartridge device which houses a group of surgical' staplers and an anvil having a staple forming surface suitable to co-operate with a proximal end surface of the cartridge device in order to clamp layers of tissue therebetween and to bend the ends of the staples when they are expelled from the cartridge device against the anvil .
- the known surgical staplers further comprise an anvil approximation device and a staple driving device.
- the anvil approximation device includes a mechanism which is configured to move the anvil towards the cartridge device in order to clamp the tissue prior to and during the application of the staples as well as to widen the distance between the anvil and the cartridge device after the stapler has been "fired” in order to release the stapled, e-9T- anastomosed, tissue.
- the anvil approximation device is often operated by a rotating knob arranged at the distal end of the handle portion and provided with a movement transmission and transformation mechanism which is functionally connected to both the rotating knob and the tissue manipulating device in order to allow to adjust the effective distance (so called "staple height") between the proximal end surface of the cartridge device and the staple forming surface of the anvil .
- the staple driving device comprises an operating member arranged at the handle portion of the stapler and a mechanism which transforms the movement of the operating member (e.g.
- a trigger lever in a movement of a staple driving platform inside the cartridge device which drives ("fires") the surgical staples out of the cartridge device, across the clamped tissue layers and against the staple forming surface of the anvil so that the staple ends are bent in a way to give the staple a more or less C or B shaped configuration.
- the tissue clamping distance between anvil and cartridge device or, in other words, the resulting staple height after "firing" the instrument is continuously adjustable in an operating range between a lower limit value (shortest possible distance and highest possible tissue compression) and an upper limit value (widest possible distance and lowest possible tissue compression) which depend upon the size of the typically initially U-shaped surgical staple loaded in the stapler.
- the staple height upper limit value corresponds to an approximately C shaped deformed staple (having substantially inwardly bent free ends) and the staple height lower limit corresponds to an approximately B shaped deformed staple (having substantially inwardly and backwardly bent free ends) .
- some modern surgical staplers are provided with an indicator device having a window with a scale divided in three distinguishable ranges - a lower range, an intermediate operating range and a higher range - as well as a pointer which is connected to the anvil approximation device such that its position on the scale depends from the staple height between the cartridge device and the anvil .
- surgeons can see from the window of the indicator device, whether the reached staple height is outside the admissible operating range for the loaded staple size (pointer is in the upper or lower range of the scale) or whether it is within the admissible operating range (pointer is in the intermediate operating range which is distinguished by color, e.g. green) .
- the object of the invention is to provide an indicator device which permits to better envision the staple features resulting from a set gap between the anvil and the cartridge device .
- an indicator device for indicating features of surgical staples corresponding to an adjustable staple height according to claim 1.
- the above object is also achieved by a surgical stapling device according to claim 18 and by a demonstration device for training, explanation and sales activity- according to claim 19.
- the dependent claims cover advantageous embodiments of the invention.
- the indicator device for indicating features of surgical staples corresponding to an adjustable staple height comprises a housing and support structure, an actuating device received in the housing and having an adjustable staple height setting member and a display device received in the housing and support structure and co-operating with the actuating device such that the display device visualizes a staple feature corresponding to a staple height set by the staple height setting member, wherein the display device is configured to visualize a deformed shape feature of the staple corresponding to the set staple height .

- the indicator device 1 comprises an elongate housing 2 which forms a handle portion 3 and supports a display device 4 with at least one display screen or window 5 arranged in an outer surface 6 of the housing 2 and visibly facing outward from the latter.
- the housing 2 further supports an actuating device 7 with an adjustable staple height setting member 8, for instance a manually operable rotary knob arranged at a distal end 9 of the housing 2 and a transmission device 10 which cooperates with both the setting member 8 and the display device 4.
- the setting member 8 allows the user to adjustably set a staple height and the display device 4 and the actuating device 7 are configured such that the display device 4 visualizes a deformed shape feature of the staple corresponding to the staple height set by means of the setting member 8.
- the display device 4 is configured to visualize the shape of the deformed staple ends 11 corresponding to the set staple height. In accordance with a further embodiment, the display device 4 is configured to visualize the shape of the entire deformed staple corresponding to the set staple height .
- the display device 4 is configured to visualize, together with the deformed shape features of the staple, at least part of a profile 12 of an anvil staple forming surface corresponding to the set staple height.
- the display device 4 is configured to visualize, together with the deformed shape features of the staple and possibly but not necessarily together with the profile 12 of the anvil staple forming surface, at least part of a profile 13 of a cartridge device end surface corresponding to the set staple height.
- the display device 4 is configured to visualize the deformed staple shape features in a magnified scale compared to the real size of a corresponding surgical staple.
- the visualized deformed staple shape features are generated with reference to a surgical staple dimension which is about 4 to 5 times larger than the corresponding real staple size. This magnification of the visualized deformed staple shape features with respect to the real staple size allows the user to immediately see and understand the deformed staple shape without any need to get the eye particularly close to the display screen or window 5.
- the display device 4 can comprise any suitable known visualization and screen display and control technology, as for instance a digital electronic display connected to an electronic control circuit which cooperates with the actuating device 7.
- a digital electronic display is a Liquid Crystal Display (LCD) .
- the display device 4 comprises an at least partially visible reversibly deformable staple dummy 14 which is configured to cooperate with the actuation device 7 such that it deforms to the visualized and preferably but not necessarily magnified deformed staple shape in dependence from the set staple height.
- the display device 4 comprises a base plate 15 connected to the housing 2 and defining a system of channels or guide grooves 16 reproducing the shape of the progressively deforming staple ends and suitable to slidably receive and guide ends 17 of the staple dummy 14 in order to reversibly deform them in progressively deformed shapes.
- the guide grooves 16 define edges 18 having approximately the shape of at least a portion of an anvil staple forming surface and, in accordance with an embodiment, the guide grooves 16 are arranged or emphasized (e.g. by color) such as to visualize at least part of the anvil staple forming surface together with the progressively deformed staple dummy ends 17 corresponding to the set staple height.
- the base plate 15 further comprises a driver guide 19 formed on a side opposite the system of guide grooves 16 and configured to slidably receive a driver portion 20 which has a shape adapted to firmly hold a basis 21 of the staple dummy 14.
- the driver portion 20 is slidably received by the driver guide 19 of the base plate 15 and the free ends 17 of the staple dummy 14 are at least partially inserted in the guide grooves 16 while its basis 21 is fixed to the driver portion.
- the guide grooves 16 act as an anvil portion and the driver guide 19 is configured such that the driver portion 20 and the anvil portion (grooves 16) are facing each other and are movable relative to one another in response to a movement of the actuating device 7.
- the free ends 17 of the staple dummy 14 enter more or less deeply into the grooves 16, thereby adopting and visualizing the more or less deformed shape of the staple ends corresponding to a set staple height.
- the staple dummy 14 comprises a generally filiform, tightly wound helical spring.
- adjustable staple height setting member 8 may comprises a rotary knob. This is particularly advantageous as the anvil movement mechanism in a surgical stapling device also comprises a rotary knob for manually approximating the anvil to the cartridge device.
- the rotary knob 8 is fixed to the housing 2 such that it is translationally locked but free to rotate about a longitudinal axis L and the actuation device 7 comprises a transmission rod 22 with a threaded portion 23 mating a corresponding threaded hole formed in the rotary knob 8 so that a rotational movement of the rotary knob 8 generates a translational movement of the transmission rod 22 which is axially movable but rotationally locked.
- the driver portion 20 of the display device 4 is connected to the transmission rod 22 through a connecting pin 24 so that the translational movement of the transmission rod displaces the driver portion 20 relative to the guide grooves 16 (anvil portion) , thereby deforming the staple dummy in dependence from the set rotational position of the rotary knob 8.
- the display device 4 comprises a scale 25 which indicates an admissible operating range 26 of staple height for a determined staple type and a pointer 27 whose position along the scale 25 is variable in dependence from the set staple height and indicates the latter on scale 25.
- a numeric staple height indication 28 e.g.
- the display device may comprise a single display screen or window 29 (as illustrated e.g. in figure 9) which visualizes all staple features, such as shape and height or, alternatively, the display device comprises a first display screen or window 5 visualizing the deformed shape feature of the staple and a second display screen or window 30 visualizing the scale 25, 28 and pointer 27.
- the first and second display screens or windows 5, 30 are arranged opposite to one another on the housing 2.
- the pointer 27 can be directly or indirectly connected to the same transmission rod 22 which acts on the driver portion 20 for the staple dummy 14.
- Figure 5A and 5B shows an exemplary illustration of the relationship of the visualized staple shape and staple height for an open staple.
- Figure 6A and 6B shows an exemplary illustration of the relationship of the visualized staple shape (B-shape) and staple height at a staple height of e.g. 2,5mm at the beginning (upper limit) of the admissible range of staple heights.
- Figure 7A and 7B shows an exemplary illustration of the relationship of the visualized staple shape (C-shape) and staple height at a staple height of e.g. lmm at the end (lower limit) of the admissible range of staple heights .
- the staple immage, e.g. the staple dummy, and also the scale 25 are preferably magnified with respect to the corresponding realistic staple size and staple height .
- FIG 8 illustrates an example of a surgical stapling instrument 31 comprising a frame 32 having a body portion 33 and a handle 34 as well as a staple fastening assembly 35 in the distal region of the instrument.
- the staple fastening assembly 35 includes a cartridge device 36 which comprises at least one row of staples and defines a distal end surface, and an anvil 37 which defines a proximal staple forming surface which is movable relative to the cartridge device 36 and adapted to cooperate with the cartridge device 36 for forming the ends of the staples exiting from the cartridge device 36.
- the stapling instrument 31 comprises further a moving device adapted to move the anvil relative to the cartridge device and a staple driving device adapted to drive the staples out of the cartridge device towards the anvil.
- the stapling instrument 31 comprises an indicator device 1 as described above.
- the indicator device may be directly implemented in the handle 34 of the stapling instrument and the actuation device of the indicator device cooperates with the moving device of the stapling instrument.
