Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Example 1:
referring to fig. 1 to 7, the present embodiment provides a cutting knife safety mechanism, which is suitable for an intracavity cutting stapler, including: a pair of symmetrically arranged safety elastic block components which are arranged in a nail bin frame 4 of the intracavity cutting anastomat and are positioned between the cutting knife 1 and the nail bin 3, and a nail pushing pry 2 which is embedded in a cutting knife groove 5 of the nail bin 3 of the intracavity cutting anastomat.
The safety elastic block assembly comprises elastic bases and elastic blocks, wherein the elastic bases are arranged on two sides of the cutting knife groove 5 respectively, and the elastic blocks are connected with the elastic bases in a matching mode; the elastic blocks respectively included in the pair of safety elastic block assemblies are suitable for blocking the cutting knife grooves 5 along the width direction of the cutting knife grooves 5; one end of the nail pushing pry 2 is suitable for extending out of one side of the nail bin 3 facing the safety bullet block assembly; and the extended end part of the nail pushing pry 2 is suitable for pushing elastic blocks respectively included in a pair of safety elastic block assemblies so that the cutting knife groove 5 is unblocked after the elastic blocks rotate around the elastic base.
Specifically, when the staple cartridge 3 is not mounted in the cartridge frame 4 (including when the staple cartridge 3 is not mounted in the initial condition or after the staple cartridge 3 is fired), the staple pushing lever 2 coupled to the cutting knife slot 5 of the staple cartridge 3 is not mounted in the corresponding position in the cartridge frame 4. In this case, the elastic blocks respectively included in the pair of safety elastic block assemblies are in a state of blocking the cutting knife slot 5 along the width direction of the cutting knife slot 5, so that the cutting knife 1 cannot cross the elastic blocks and enter the cutting knife slot 5, that is, the elastic blocks respectively included in the pair of safety elastic block assemblies form a stop for the pushing-out of the cutting knife 1 in this state to prevent the cutting knife 1 from being pushed out by an unnecessary trigger. And after the nail bin 3 is arranged in the nail bin frame 4, the nail pushing pry 2 connected with the nail bin 3 is also arranged in place along with the nail bin 3, the groove 21 on the nail pushing pry 2 is just matched and connected with the boss 31 of the nail bin 3, and one end of the nail pushing pry 2 can extend out of one side of the nail bin 2 facing the elastic block, so that one end of the nail pushing pry 2 can generate the pushing action on the elastic blocks respectively included by the pair of safety elastic assemblies, the elastic blocks respectively included by the pair of safety elastic assemblies can rotate relative to the elastic base to remove the blockage of the cutting knife slot 5, and under the condition, the elastic block can not block the cutting knife 1 from moving along the cutting knife slot 5.
The nail pushing pry 2 and the cutting knife slot 5 of the nail bin 3 are matched and connected through the following structures: a pair of bosses 31 are symmetrically arranged on the groove wall of one end of the cutter groove 5 close to the cutter 1; and a pair of grooves 21 which are suitable for being matched with the pair of bosses 31 in a one-to-one correspondence manner are arranged on two side walls of the nail pushing pry 2. The nail pushing pry 2 of the embodiment can be made of medical high polymer plastic materials. The nail pusher 2 is adapted to move linearly along the cutter groove 5 under the pushing action of the cutter 1. In detail, when the nail pushing pry 2 is not acted by external force, the nail pushing pry 2 is limited in the cutting knife groove 5 through the matching of the groove 21 and the boss 31 of the cutting knife groove 5. And because the medical polymer plastic material of making and pushing away nail sled 2 itself has certain elastic deformation effect, so make push away nail sled 2 and receive under the impetus of promoting can make recess 21 break through the limiting displacement of boss 31 and make holistic push away nail sled 2 can be in cutting sword inslot 5 rectilinear movement.
More specifically, the elastic block of the present embodiment includes a U-shaped base 61, and a pair of engaging lugs 62 coupled to an opening of the U-shaped base 61; the elastic base comprises a pin 71 which penetrates through the pair of connecting lugs 62 to be fixedly connected with the nail bin frame 4, and a spring 72 which is sleeved on the pin 71 and is positioned between the pair of connecting lugs 62; the resilient block is adapted to rotate about the pin 71. With reference to the drawings of the present embodiment, taking the case that the spring 72 is a torsion spring as an example, one end of the torsion spring abuts against the inner side wall of the magazine rack 4; and the other end head of the torsion spring is abutted against one side end of the U-shaped base body 61 departing from the nail bin 3. That is, the elastic blocks included in the pair of safety spring block assemblies respectively can be in a state of blocking the cutting knife groove 5 along the width direction of the cutting knife groove 5 by the action of the torsion spring without being acted by the nail pushing pry 2.
In an alternative embodiment, when the elastic blocks of the pair of safety spring block assemblies block the cutting knife grooves 5, a small gap exists between the U-shaped bases 61 of the elastic blocks of the pair of safety spring block assemblies, and the small gap is smaller than the space required for the cutting knife 1 to pass through, so that when the elastic blocks of the pair of safety spring block assemblies rotate around the elastic bases under the action of the nail pushing pry, the U-shaped bases 61 of the pair of elastic blocks do not generate relative friction under the setting of the small gap.
In a further alternative embodiment, when the elastic blocks respectively included in the pair of safety spring block assemblies block the cutting knife grooves 5, the U-shaped bases 61 of the elastic blocks respectively included in the pair of safety spring block assemblies contact with each other, and in this case, it should be further noted that the contact surfaces of the U-shaped bases 61 of the elastic blocks respectively included in the pair of safety spring block assemblies are arc surfaces, so that the mutual influence of the pair of elastic blocks respectively rotating around the elastic base during the contact of the arc surfaces can be reduced.
It should be further noted that, in order to effectively ensure that the elastic blocks respectively included in the pair of safety elastic block assemblies can maintain the stability under the condition of blocking the cutting knife slot 5, an abutting effect of one end of the torsion spring is provided at one side end of the elastic block away from the magazine 3, and a limit block 41 suitable for stopping and limiting the U-shaped base body 61 is further convexly provided in the magazine frame 4 and between the magazine 3 and the U-shaped base body 61 at one side end of the elastic block facing the magazine 3 for keeping the elastic block at an effective position. Therefore, the limiting block 41 and one end of the torsion spring respectively form an abutting action on two side end faces of the elastic block, so that the elastic block can be kept in an effective position state for blocking the cutter groove 5, and in combination with the attached drawings of the embodiment, the elastic block can be in a position state for vertical cutting the cutter groove 5, so that a pair of elastic blocks jointly form a vertical blocking effect for the cutter groove 5. In addition, in this case, even if the cutting knife 1 pushes away the elastic blocks respectively included in the pair of safety elastic block assemblies by force, the elastic blocks exert a pushing action force, and the elastic blocks cannot rotate towards the direction of the magazine under the stopping action of the limiting blocks 41, so that the elastic blocks can be effectively kept in a blocking state for the cutting knife slot 5. That is, in the case that the elastic block exerts a force to rotate around the elastic base, the elastic block can only rotate around the elastic base in the direction away from the nail bin 3 under the action of the nail pushing pry 2 to realize the blockage removal of the cutter groove 5.
The specific implementation principle of the cutting knife safety mechanism of the embodiment is as follows:
when the nail bin 3 and the nail pushing pry 2 are not installed in proper positions in the nail bin frame 4, the elastic blocks respectively included by the pair of safety elastic block assemblies at the moment are in a vertical state relative to the cutting knife groove 5 under the action of the torsion spring, and the elastic blocks block the cutting knife groove 5 at the moment, so that the cutting knife 1 cannot cross the elastic blocks and can be smoothly pushed out. And after the nail bin 3 is installed to a proper position in the nail bin frame 4 along with the nail pushing pry 2, the nail pushing pry 2 at the moment generates an elastic block which respectively comprises a pair of safety elastic block assemblies and rotates around the pin 71 towards the cutting knife 1, so that the elastic block can leave the cutting knife groove 5 to remove the blockage of the cutting knife groove 5, under the condition, the cutting knife 1 can be smoothly pushed out along the cutting knife groove 5, in the process that the cutting knife 1 is pushed out, the cutting knife 1 generates a pushing effect on the nail pushing pry 2, and the nail pushing pry 2 can linearly move along the cutting knife groove 5.
