Description

one

Surgical stablifting tools are known that contain an elongated corus, a handle, a drive part, a flat pushing part, the working part of which has a pair of V-shaped grooved stems, and a replaceable staple clip. A disadvantage of the known tools is that they do not provide a uniform bend in the brackets when sewing the fabric and the boat is designed to bring the fabric down.

The proposed surgical stablifting tool differs from the known ones in that in order to uniformly bend the staples without placing the stop under the tissue to be stapled, the staple holder has manholes with an inclined plane at its working part; an anvil located at the right side of the longitudinal axis of the clip, the length of which is less than the loierechny side of the bracket; and to display curved brackets; a flat pushing part located in the plane of the stop, the distance between the V-shaped protrusions of this part being equal to the length of the unor and two diameters of the bracket; two parallel screws, in which the recesses of the cutting are brackets on one side, the depth of the last turns of cutting located at the working part of the yoke decreases to zero, and on the other hand there is a movable indicator in the recesses of the cutting that overlaps the holes in the bottom holder casing and indicating the number of left brackets. The gas-power drive is kyematically connected through a gear mechanism with a nlokoy pushing part and two parallel screws.

In addition, for uniform feeding of the staples to the working part of the cage, after each parting, the drive part with the inclined plane may come into contact with the inclined

Iodular plane of an inoperative plunger connected through a pivotal triangular bar with a gear mechanism, worn out as a pinion gear and located in the shaft with two driven gears, the axes of which are connected to the axes of the parallel screws of the clip bracket.

The gas power drive of the tool can be made in the form of a cornus, the gas inlet of which is blocked by a sleeve, and inside the corulus there is a piston with a seal, a spring and a rod, while the brush is connected to the internal part and the seal, which form two chambers with outlet and valve holes . Such an implementation of the tool will provide a constant force of bending of the brackets and a reciprocating movement of the flat pushing part. In order to eliminate manual efforts and actuation of the sniVay1, its mechanism. A replaceable gas canister can be installed in the tool, equipped with a tubular needle to puncture the seal in its throat and with a sealing tube. FIG. 1 shows schematically the proposed instrument in general form; in fig. 2 - a tool with a clip installed in it; in fig. 3 - clip, top view; “And FIG. 4 - the same, bottom view; pas figs. 5 - Rear part of the Clip without a cap; in fig. 6 is a cross section but A - A of FIG. five; in fig. 7 - section along B - B fig. 6; in fig. 8 - the front part of the holder with a partially disposed cover; in fig. 9 - section along B - B f. 8; in fig. 10 - section along G - D fig. eight; in fig. 11 - clip, front view; in fig. 12 - pusher, and detail, top and side view; in fig. 13-17-successive stages of the gas-powered drive; in fig. 18 is a gear mechanism, top view; in fig. 19 - the same, side view; in fig. 20 is a cross section along E-D of FIG. 18; in fig. 21 is a section along E - E of FIG. 18, the position in which the tool is cocked and ready to operate; in fig. 22 - the position of the triangular bar and associated with the details with the introduction of brackets; FIG. 23 - the position of the same parts at the moment of their return to the initial state; in fig. 24 is another embodiment of the proposed instrument, an abundance view; in fig. 25 is a section along G - G FIG. 24; in fig. 26-Sequential bending staples; in fig. 27 consecutive steps for stapling into stapled fabric. In the handle 1 of the elongated body 2 of the described tool, the gas-powered drive 3 is stirred. A replaceable staple holder 4 is attached to the front end of the Cornus. This connection is dried by inserting the holder into the housing, its configuration 5 allows you to insert the holder at an angle to the axis of the hull. The yoke is fixed in the housing by means of a semi-cylindrical cam 6, which, when rotated by 180 °, comes into tight contact with the cam groove 7 in the lower part of the yoke and holds the yoke in a position where its axis is parallel to the yoke axis. This is also provided by flanges 8 extending upwardly from the closure plate 9 of the yoke. The flanges are included in a pair of recesses 10 made in the receiving device 5 of the housing. The flanges are spaced apart at some distance (see Fig. 11), so that between them a drive piece 11 with an elongated middle part 12 can reciprocate. At the very front end of the drive part there is a protrusion 13, and in the middle its parts are inclined plane 14. The flat panel of the drive part interacts with the inclined plane of the movable plunger 15, which is pressed against the drive part by a spring 16. As the drive part moves forward, its inclined plane acts on the inclined plane Luner and mix it against the action of the spring down. The clip 4 comprises a housing 17, which is closed by a plate 9. On the housing there are two lugs 18 that interact with recesses on the closing plate. In the housing of the holder there are also two cylindrical recesses 19 extending along the entire length of the housing. Two parallel screws 20 with shanks 21 terminating in flat flanges 22 are located in these recesses. Two recesses 23 are also made in the housing, which form a channel for guiding the moving cKOi6oK 24. The brackets move through this channel with screws 20, in recesses 25 of which they are cut are found. At the top, said channel with brackets is closed by a flat pushing part 26 sliding in a recess 27 made in the closing plate 9, the movement of the pushing part being made between the upper part of the screw 20 and the lower surface of the closing plate. Detail 26 has two protrusions 28 located at its center. These protrusions slide in the recesses 29 of the cover plate 9. The rear part of the pushing part has a shaft 30, into which the protrusion 13 of the drive part 11 enters. This protrusion extends into the window through the slot 31 in the closing plate 9. The front part of the pushing part is provided with two projections 32 V -shaped, with each protrusion having a groove 33 under the brackets 24. The front part of the closing plate 9 hangs over the pushing member 26 and forms an emphasis 34 located perpendicular to the longitudinal axis of the yoke 4. The length of this emphasis is smaller than the transverse side of the bracket 24. The emphasis equipped with springs 35 for withdrawing curved brackets. At the same time, the pushing part retracts the springs from the bending plane of the brackets during the step of folding the brackets and releases these springs when the part 26 begins to retreat. When the pushing member retracts from the abutment of the spring 35, the bent bracket is pushed out of the plane of the pushing member 26 (see Fig. 9). The distance between the V-shaped protrusions of the pushing part is equal to the width of the stop 34 plus the doubled amount of brackets and plus the small gap necessary to avoid jamming the brackets. When charging the holder with brackets, screws 20 are installed in the corresponding cylindrical recesses 19 so that the flat flanges 22 of the shanks of the screws are in a vertical position. Brackets are placed in the channel 23 so that their transverse sides lie in the grooves 25 of the threading screws, and the sharp ends are directed toward the stop 34. Then the pushing part 26 is installed above the brackets and the plate 9 is closed. 1 tool.

Screws 20 are cut in such a way that, when rotated by 360 °, each bracket moves one step, which is defined as the distance required to move the front bracket from the ready position to the installation position (or bending). FIG. 8 and 9 "the bracket bracket is indicated by the letter a. Thus, the first bracket is at a distance of one step from the position of the bend, while the pushing part 26 is in the rear position; in which all the brackets are held in the recesses 25 of the thread KI and the screws 20.

The front ends of the guides 36 of the channel 23 for the brackets end with inclined planes 37, which serve to direct the very front (first) bracket up into the plane of the pushing part 26 while it is moving forward. At the same time, the side of the bracket is transferred to the plane of the pushing part. This is due to the special design of the front part of the screws 20 (see Fig. 10): in the front part of the screw, in the working part of the yoke, the depth of the last turns: the cutting is reduced to zero. So, if the cutting depth at point 38 of the screw is equal to the depth of cutting along the entire screw, then at point 39 this depth is equal to zero (arrow 40 indicates the direction of screw rotation when pushing the brackets out). Thus, moving along the grooves of the screw cutting, at point 39, the transverse side of the bracket rises to the plane in which the pushing member 26 moves.

In the lower part of the housing 17 of the yoke under the cylindrical recesses 19, rectangular grooves 41 are selected, extending along the entire length of the housing and communicating with the recesses. In addition, through the conical holes 42, located in two rows in a checkerboard pattern and spaced one screw apart from each other, are drilled from the bottom side of the body under the notches and grooves. The number of these holes is equal to the number of brackets laid in the yoke (for example , 25). Each such hole coaxes with the grooves 41 and recesses 19 by means of cylindrical holes 43, the diameter of which is smaller than the diameter of the narrowest part of the conical holes 42. Two slots 44 and 45 of rectangular shape, provided with cylindrical projections 46, move in the grooves 41. Cylindrical projections enter from the bottom into the recesses 25 of the threading screws, during the rotation of which the inserts move in the rectangular grooves 41. In doing so, they alternately (due to the staggered arrangement of the holes 42) cover these holes, so that through the holes 42 en only one of any of the inserts 44 or iS. Initially, the liners are flush with the back of the yoke (see Fig. 4). Under the outermost hole marked with the number “25, is the liner 45. This means that there are twenty five brackets in the holder. After removing one bracket from the store, each of the outlets 20 makes one complete turn, while the inserts are moved one screw turn. Since the holes are spaced apart by one screw pitch, with one turn it is in the nearest hole from the other row along the liner 44. In this case, this nearest hole will be the hole denoted by 24, which indicates how many brackets are left in the holder . This alternate appearance of the liners in the conical holes will continue until the insert 45 is in the hole.

indicated by the numeral “1, thus indicating that only one bracket remains in the holder. When the last bracket is removed from the holder, the inserts will not be seen through the holes. Thus, the inserts are movable indicators covering the holes in the bottom of the casing and indicating to the surgeon the number of brackets left in the tool. The rotation of the cylindrical screws 20 of the bracket cage is carried out by means of a gear mechanism mounted in the middle part 47 of the tool body 1 (see Fig. 2 and 18-23). The gear mechanism is driven by a spring-loaded plunger 15, which cooperates with the inclined plane 14 of the actuating member 11. The latter is displaced progressively with a brush 48, one end of which is connected to the gas-powered actuator 3, and the other to the plug 49 in the rear part of the drive part. When the drive is activated, the stem, the drive part, and the pushing member move forward. In doing so, the bracket presses against the anvil 34 and bends into a rectangular shape.

At the same time, as the drive part moves forward, its inclined plane 14 acts on the plunger, moving it down against the action of the spring 16. On the front surface of the plunger there is a groove 50,

which includes a flange 51, mounted in the lower part of the rear surface of the triangular carrier base 52 of the gear mechanism. When moving the plunger down, the flange also moves down, thanks to which

the triangular plate rotates around axis 53. In FIG. 2 and 21 show the relative position of the plunger and the triangular carrier plate at the moment when the driven part is not in contact with the plunger. FIG.

22 shows the moment when the barrel is interacting with the inclined plane 14 on the driving part in the process of bending the bracket. From the comparison of these figures, it can be seen that when moving the nunger down, the carrying

The baseline is rotated about axis 53 in a counterclockwise direction.

A lever 55 is mounted on the triangular plate and on the axis 54, the front part of which is in contact with the surface of the six-teeth

ratchet wheel 56. However, in the idle position, the lever does not touch the teeth of the temple wheel. The movement of the lever is limited by an axis 57 mounted on the rear surface of the lever and passing through the opening 58 in the plate 52. The second lever 69 is mounted on the axis 60 fixed on the housing of the gear mechanism, and is thus independent of the plate 52 and the lever 55 The levers 55 and 59 are pressed against the ratchet wheel by a spring 61. The lever 59 serves as a stop to restrict the rotation of the ratchet wheel.

At the bottom of the plate 52 there is a protrusion, in KOTOipoM an axis 62 is installed, interacting with the cam 63. On the same axis as the ratchet wheel and the pin 63, the drive gear 64 of the gear mechanism is installed, so that these parts turn together. The driving bar is in engagement with two driven small 65 brushes. The ratios between the diameters of gears 64 and 65 are selected so that when turning the ratchet wheel at an angle from one tooth to the next, each of the driven gears rotates one turn. Each of the small gears is mounted on the corresponding axis 66, the front end of which is provided with a slot 67. Flat flanges 29 are inserted into these slots on the shanks of parallel sleeves. When the driven gears are rotated one turn, the screws 20 associated with them are rotated and the brackets are moved forward by one "step".

Before the operation of ejecting the staple from the yoke when the driving part is in the rearmost position and the plunger in the upper position, the triangular plate 52 is in the position shown in FIG. 21. At the same time, the lever 59 is engaged with the ratchet tooth.

The working surface of the lever 55 is retracted from the nearest tooth on the ratchet wheel, allowing the plate 52 to have a small free play before the wheel begins to turn. In this case, the axis 62 extends out of the recess on the cam 63.

As the drive unit moves forward to perform the pushing operation of the bracket, the plunger, overcoming the resistance of the spring 16, moves down.

The carrier plate 52 rotates in a counterclockwise direction around the axis 53, and the lever 55 rotates the ratchet wheel.

FIG. 22 shows the mutual position of the gear parts after the lever 55 has turned the ratchet wheel to its maximum angle. This maximum angle is larger in magnitude than the angle of rotation required for brackets to perform one step. As a result, the gears receive an additional offset along the circumference. However, the gears are initially in the idle position, while the gear unit is retracted, awaiting an initiating strike. The axis 62 is engaged with a recess in the cam 63, with the result that the ratchet wheel, the pinion gear and the two driven gears are in the locked position. In this position, slots 67 are positioned as shown in FIG. 18, which allows for easy insertion or removal of the clip. When triggered gas-powered drive 3

the drive piece is fed forward and its inclined plane 14 pushes the plunger downward, while the plunger carries the plate 52, which rotates in a counterclockwise direction.

During the initial movement of these parts of the gear mechanism, gears 64 and 65 are not rotated. The gap between the lever 55 and the closest tooth of the ratchet wheel allows the axis 62 to exit the cavity with a recess on the cams 63 before the gears begin to turn. Then the lever 55 engages a ratchet tooth and rotates it, with the drive gear and driven gears turning to the position shown in FIG. 22. The gears are shown at an additional circumferential offset when they are shifted by a greater distance on the wheel | than is required to move the brackets one step. it

provided for the slots 67 connected to the axles 66 of the driven gears to be in a position convenient for insertion and removal of the staple from the tool

0; battle) WE 4.

After ejecting the staple, the drive part moves in the rearward direction, while the plunger moves up, sliding along the inclined plane 14. This movement causes the carrier plate 52, and therefore the axis 62, to squeeze the position shown in FIG. 23. From this position, the spring 16 forces the axis 62 to press against the surface of the cam 63. Since this cam is in the locked position, the movement of the axis 62 causes the cam to rotate in a clockwise direction. This rotation continues until the gear mechanism occupies the initial position shown in FIG. 21, i.e. the position

ready for the next operation of ejecting the staple.

The movement of the drive part is carried out by a gas-powered drive 3, made in the form of a housing 68, having an inlet gas opening 69, which is blocked by a sleeve 70 (see fitting 13-17). The sleeve is connected to the two seals 71 and 72 in the form of diaphragm. From one end of the sleeve to the other passes the transition channel 73. Inside the housing 68 is a piston 74 with a seal 75 in the form of a movable diaphragm. The piston moves in chamber 76 and is pressed to the top by a spring 77.

The piston 74 is attached to the rod 48, on which there is a notch 78. The upper part 79

the rod under the action of the spring 77 exerts pressure on the sleeve 70. The sealing bead 80 at the gas inlet serves to prevent gas from leaking at the point of contact between the inlet and the sleeve. The gas force actuator has 81 connected to the valve chamber 82 and the exhaust port 83 connected to the exhaust chamber 84. The inlet chamber 85 is connected to the inlet 69.

"When the spring 77 acts on the sleeve 70 through the upper part 79 of the stem 48, this sleeve is pressed against the sealing shoulder 80, thus preventing the passage of compressed gas into the inlet chamber 85. The pressure acting on the upper part of the sleeve is smaller than the force acting springs.

The gas-power drive is driven by trigger fur with a measure 86, which can rotate about axis 87. The front end of the trigger mechanism enters a notch 78 made on the shaft. When the trigger mechanism 86 is pressed, the gas entering the hole 69 overcomes the spring force by acting on the sleeve 70, while the sleeve moves downward from the sealing lip 80 of the entrance hole. When the bushing reaches the bottom of the exhaust chamber 84, the exhaust port 83 is closed from compressed gas in the inlet chamber 85. The compressed gas passes through the inlet to the inlet chamber 85, then through the transition channel 73 to the piston chamber 76. The pressure of the compressed gas causes the piston to move down to the position shown in FIG. 15.

Initially, the pressure in the plenum chamber 76 is lower than the pressure in the inlet chamber 85 under the action of the restrictive transition channel 73. However, the pressure in the piston chamber rapidly increases until it exceeds the increase in pressure in the inlet chamber. The pressure in the pressure chamber becomes greater than the pressure in the inlet chamber due to the fact that the pressure in the pressure chamber acts on a larger area (lower part of the sleeve 70) than the pressure in the input chamber, which acts on the upper part of the seal 71. As a result of this pressure difference The pressure in the pressure chamber 76 forces the sleeve 70 to move upwards, thus closing the inlet when the sleeve contacts the sealing lip 80 (see Fig. 16). The pressure in the piston chamber 76 at this time is directly proportional to the ratio of the areas of the upper and lower diaphragm seals 71 and 72. Then the pressure in the system is equalized. Now the gas in piston chamber 76 can escape to the atmosphere through a limited exhaust port 83. At this time, spring 77 pushes the piston 74, creating pressure on the lower seal 72 and thus holding sleeve 70 in its pressed position relative to the sealing shoulder 80 This continues until the upper part 79 of the brush is in contact with the sleeve 70. With this contact under the action of the spring 5, the sleeve is held pressed against the shoulder. The intermediate position is shown in FIG. 17, and the final stage corresponds to FIG. 13 (i.e. the starting position). When the gas-powered drive takes up this position, 10 it is ready for the next operation. It should be noted that in all gas-powered drive chambers, with the exception of only the inlet zone, the pressure is maintained at atmospheric pressure. A pinch 88, made at the top of the stem, allows chamber 85 to be connected. regardless of the contact between the upper part of the brush and the transition channel 73. In order to avoid sudden, uneven operation, the gas power actuator is equipped with a valve 81, which is connected to the valve chamber 82. Due to the ITAL diaphragm seals 71 and 72, the pressure is increasing. five

Compressed gas in the gas-power drive comes from interchangeable cartridges 89. The cartridge can be installed, for example, in a special handle 90 (see Figures 24 and 25) and 0 is screwed down with a screwed-in plug 91. The cartridge is filled with gas under pressure, for example Carbon dioxide The gas from this cartridge is supplied to the gas-powered drive through the channel 92, which opens into the inlet 69. The neck of the cartridge is equipped with a conventional seal 93. The neck of the cartridge enters the sealing sleeve 94 and the ring-shaped washer 95 serves for sealing the junction between the mountains of the L0WIN spray can and vtlkoy. The needle for puncturing the cartridge seal is interposed facing the inside of Llattpem 96, SLEEVES and the seal of the cartridge. The needle contains a BODY 97, a pointed part 98 and 5 of the 10-110 part with a slot 100. An internal channel 101 passes along the needle axis.

When screwing in cork 91 into the handle

the canister is pressed against the base 102

103. With this movement, XIBO0, Stoke Part 99 abuts base 102 and

pointed needle section 98 pierces

seal 93 cartridges. From spray can

the gas rushes through the internal channel 101,

comes out of slot 100 and enters the chamber,

 formed by drilling 103.

Vlta 94 has a thin elastic expansion 104 that is in contact with the wall of drilling 103. When the compressed gas passes into this drilling, it rushes, 1 into space, with the main part of the sleeve and the elastic expansion, thus pressing it to the wall of the drilling. As a result of this arrangement of parts, gas cannot pass back to the handle.,

AND

When using the tool, the surgeon after charging the holder with 4 brackets and installing it in the housing 1 presses the tool stop 34 to the skin and presses the trigger mechanism 86, and HITOK 48 not moving forward in direction to clip. Together with it, the driving part 11 moves forward. On the one hand, it acts with its inclined plane 14 on the tunneler 15, moving it downwards, and on the other side of the protrusion m 13 - on the pushing member 26. When the plunger moves, the gear mechanism The parallel screws 20, which move the brackets 24, rotate. When moving, the pushing part 26 pulls itself at the end of the speed and presses it against the stop 34 (see Fig. 26 and 27). Upon further advancement of the pushing part due to the presence of grooves 33 in its V-shaped protrusions 32, the bracket easily bends around the anvil and finally takes a rectangular shape. Its ends are in contact with each other. The beveled surface of the protrusions 32 of the pushing part provides pressure on the skate when it is pushed and, in places remote from the stop 34.

In the extreme forward position of the pushing member, the protrusions 32 remove the arms 35 from the plane of the bracket. After a complete insertion of the okobdai, when the pushing part begins to return to its original position, the springs are triggered, releasing the bracket from the stop. The stitched damaged skin area is then straightened under the influence of the elasticity of the subcutaneous tissue and fills the space under the bracket. Then the tool is pressed against the next point of the damaged area and the next bracket is inserted here, and so on, until the entire damaged skin area is sewn.
