[0041] In order to ensure the correct installation of the instrument, avoid medical accidents caused by accidental touch, and improve the safety and reliability of the operation, the utility model discloses a microsurgical operation instrument with an anti-misoperation mechanism, and the preferred embodiments of the utility model will be described below with reference to the drawings.

[0042] The microsurgical operation instrument with the anti-misoperation mechanism in the utility model embodiment is used in high-precision microsurgical operation, and the design of the instrument can be used in cooperation with a robotic surgical system.

[0043] The sterile adapter A in the surgical robot is an important component for ensuring the sterile isolation between the instrument and the driver during the operation.

[0044] The instrument box in the utility model embodiment is installed on the sterile adapter, and the sterile adapter is installed on the power output mechanism of the microsurgical robot.

[0045] Referring to Figure 1 The microsurgical operation instrument with the anti-misoperation mechanism in the utility model embodiment contains an instrument box structure, and the instrument box includes an instrument box shell 1 and an instrument box base 2.

[0046] A button foolproof block is installed in the cavity, and the button foolproof block is provided with a containing cavity 31.

[0047] See Figure 4 As shown, a button anti-fooling block is installed inside the cavity, and the button anti-fooling block is provided with a receiving cavity 31. A mirror-symmetrical instrument box button 5 is provided on each of the two opposite sides of the instrument box shell 1, see reference. Figure 3 As shown, the instrument box has symmetrical button mounting holes. These buttons, located on one side of the cavity, have a limiting protrusion 51 that interacts with the button anti-fool block. The button anti-fool block is roughly rectangular, with the receiving cavity 31 located at the upper part. The receiving cavity can be a through hole or a countersunk hole, as long as it can accommodate the limiting protrusion 51 and has a certain depth, allowing the lug 14 on the button to press down the latch 8, so that the head of the latch 8 can completely pass through its mounting hole 15.

[0048] See Figure 10 As shown, the instrument box base 2 outside the cavity is detachably connected to the sterile adapter A; the end of the button anti-fool block away from the first compression spring 6 passes through the guide hole on the instrument box base 2 and falls on the boss 82 of the sterile adapter A. The sterile adapter A is provided with symmetrical buckles 8, and the instrument box base 2 is provided with mounting holes 15 for the buckles 8. The buckles 8 pass through the mounting holes 15 on the instrument box base 2 and extend into the cavity to lock onto the instrument box base 2. The buckles 8 include a release surface 81, and the lower edge of the instrument box button 5 contacts the release surface 81; the button anti-fool block is connected to the instrument box shell 1 through the first compression spring 6. The two instrument box buttons 5 can move towards or away from each other to realize the pressing and resetting of the buttons.

[0049] See Figure 10 and Figure 11 As shown, when the boss 82 of the aseptic adapter A pushes the button anti-fool block against the instrument box shell 1, the receiving cavity 31 on the button anti-fool block moves to the corresponding position of the limiting protrusion 51. At this time, the instrument box button 5 can only be pressed when the aseptic adapter and the instrument box are installed in place. When the two instrument box buttons 5 move towards each other, they drive the limiting protrusion 51 to move into the receiving cavity 31. The lower edge of the instrument box button 5 abuts against the release surface 81, causing the buckle 8 of the aseptic adapter A to disengage. Conversely, if the aseptic adapter and the instrument box are not installed in place during the installation process, the button anti-fool block will function, preventing the instrument box button 5 from being pressed inward, thus avoiding misoperation during the installation process.

[0050] Outside the cavity, the instrument box base 2 is detachably connected to the sterile adapter A. The sterile adapter A is provided with symmetrical buckles 8, which are locked and released through the release surface 81.

[0051] See Figure 4 and Figure 6 As shown, each instrument box button 5 is equipped with two symmetrical second compression springs 11; the second compression springs 11 are located inside the cavity, one end of which is fixedly connected to the instrument box button 5, and the other end is fixedly connected to the instrument box shell 1.

[0052] As shown in Figure 4 and Figure 7 As shown in, the parallel button pressing plate 12 is fixedly installed below the inner side of the cavity, the button pressing plate 12 is fixedly connected with the other end of the second compression spring 11, and the button pressing plate 12 is fixedly connected with the first compression spring 6 away from the inner side of the cavity. In order to enhance the operability of the instrument box button 5, two symmetrical second compression springs 11 are installed on each button. The second compression spring 11 is located in the cavity, one end of which is fixedly connected with the instrument box button 5, and the other end is fixedly connected with the instrument box shell 1.

[0053] As shown in Figure 5 As shown in, the instrument box button 5 is provided with a guide block 13 between the button pressing plate 12 and the inner side of the instrument box shell 1, so that the instrument box button 5 can move in the direction parallel to the button pressing plate 12. The button pressing plate 12 is fixedly installed below the inner side of the cavity and is fixedly connected with the other end of the second compression spring 11. The button pressing plate 12 is fixedly connected with the first compression spring 6 away from the inner side of the cavity. The button pressing plate 12 and the inner side of the cavity are in a fixed connection relationship, which can be fixed by screws or glueing. The screw connection is adopted in the embodiment of the utility model, and the button pressing plate 12 is provided with a countersunk hole 17 away from the inner side of the cavity, which is used for being fixed on the instrument box shell by screws.

[0054] The lower edge of the instrument box button 5 is provided with a lug 14 matched with the tripping surface 81, the lug 14 presses the head of the two buckles 8 to the opposite side to be inclined, so that the head of the buckle 8 can pass through the mounting hole 15 on the instrument box base 2 and be tripped from the instrument box base 2. The lower edge of the instrument box button 5 is provided with a lug 14 matched with the tripping surface 81, the lug 14 presses the head of the buckle 8 to the opposite side to be inclined, so that the buckle 8 is tripped. When the boss 82 of the sterile adapter A lifts the button anti-fool block towards the instrument box shell 1, the accommodating cavity 31 on the button anti-fool block moves to the position corresponding to the limiting protruding part 51. At this time, the two instrument box buttons 5 move towards each other, drive the limiting protruding part 51 to move into the accommodating cavity 31, and the lower edge of the instrument box button 5 abuts against the tripping surface 81, so that the buckle 8 is tripped.

[0055] The mounting hole 15 of the buckle 8 is formed on the instrument box base 2, and the diameter of the mounting hole 15 is at least greater than the size of the head of the buckle 8, so as to facilitate the installation and disassembly of the buckle 8. The limiting part 16 is arranged in the instrument box shell 1 and located on both sides of the guide block 13 on the instrument box button 5, and is used for limiting the movement of the guide block 13 in the direction perpendicular to the line connecting the two instrument box buttons 5.

[0056] The limiting part 16 is arranged in the instrument box shell 1 and located on both sides of the guide block 13 on the instrument box button 5, and is used for limiting the movement of the guide block 13 in the direction perpendicular to the line connecting the two instrument box buttons 5.

[0057] The guide hole of the instrument box base 2 is provided with a stop table, and the upper part of the button fool-proof block can be above the stop table. The accommodating cavity 31 of the button fool-proof block is in a relative position with the limiting protruding part 51 on the instrument box button 5.

[0058] The outer side of the instrument box button 5 is provided with anti-skid lines 18 for facilitating internal pressure. In order to facilitate the internal pressure of the operator, the outer side of the instrument box button 5 is provided with anti-skid lines 18, so as to improve the stability and accuracy of operation.

[0059] The working principle of the anti-mis-touch mechanism surgical instrument of the utility model is based on a delicate mechanical linkage system, which ensures that the instrument can only be disassembled when it is correctly installed in place. The instrument box is internally provided with a button fool-proof block, which is provided as a column in this embodiment, and the upper part of the column is provided with an accommodating cavity 31, which is connected with the instrument box shell 1 through a first compression spring 6. The instrument box shell 1 is also internally provided with a button pressing plate 12, which is a horizontally placed cross, and the two free ends thereof are fixedly connected with one end of the first compression spring 6. Before the sterile adapter A is not installed in place, the instrument box button 5 is limited by the fool-proof block, so as to prevent it from being accidentally pressed. When the instrument is correctly installed on the sterile adapter A, the boss 82 on the adapter lifts the button fool-proof block, thereby releasing the limitation of the instrument box button 5. At this time, the instrument box button 5 can be pressed. The pressing action of the instrument box button 5 pushes the limiting protruding part 51 into the accommodating cavity 31, thereby triggering the release of the buckle 8 on the sterile adapter A. The release surface 81 of the buckle 8 is in contact with the lower edge of the instrument box button 5, thereby realizing the release. In addition, each instrument box button 5 is provided with a symmetric second compression spring 11, which provides necessary elastic force, thereby ensuring the smoothness of the button operation. The button pressing plate 12 is fixedly connected with the other end of the second compression spring 11, and the guide block 13 ensures the movement of the button in the correct direction. When the instrument needs to be disassembled, the operator presses the instrument box button 5, thereby realizing the release of the buckle 8 through the cooperation of the lug 14 and the release surface 81, so as to safely disassemble the instrument. The design of the whole system avoids the problem of incorrect installation caused by mis-touch, thereby greatly improving the safety and reliability of the use of the surgical instrument.

[0060] Obviously, those skilled in the art can make various modifications and variations to the utility model without departing from the spirit and scope of the utility model. Thus, if these modifications and variations of the utility model belong to the scope of the claims of the utility model and the equivalent technologies thereof, the utility model also intends to include these modifications and variations.
