The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The utility model discloses a first embodiment:

as shown in fig. 1, in the present embodiment, the surgical device includes a lever 100 and a control adapter 200. The operating rod 100 has a surgical instrument at one end and a handle 110 at the other end. The control adaptor 200 includes a rotation shaft 210, a bushing 220, a torsion wheel 230 as a rotation member, a limit collar 240, and a stopper member 250. As shown in fig. 2, the shaft 210 is provided with a passage 211. As shown in fig. 1, the operating lever 100 passes through the passage 211 and is fixedly coupled to the rotary shaft 210 through the handle 110. The shaft sleeve 220 is sleeved on the outer side of the rotating shaft 210, and the torsion wheel 230 is also sleeved on the outer side of the rotating shaft 210 and is fixedly connected with the shaft sleeve 220. The limiting ring 240 is also sleeved outside the rotating shaft 210 and is fixedly connected to the shaft sleeve 220.

It should be noted that the torsion wheel 230 is only one of the rotating structures, and the rotating structure may also be a plurality of rotating thin rods fixed on the shaft sleeve 220. Meanwhile, the torsion wheel 230 and the shaft sleeve 220 may be fixedly connected together or may be integrally formed.

When using the surgical device, the operator needs to hold the handle 110 with his hand and then rotate the handle 110 by turning his wrist to control the surgical instrument at the other end of the operation rod, so as to perform the corresponding surgical operation. However, in a state where the handle 110 is held by a hand, the rotation angle of the wrist of the operator is limited, and when the rotation angle exceeds a certain angle, it becomes difficult to rotate the wrist of the operator again, and at this time, the operator's wrist is uncomfortable due to the continued rotation, which affects the control of the surgical instrument by the operator, and adversely affects the surgical effect. At this point, the operator may manipulate the surgical instrument by turning the torsion wheel 230, thereby controlling the surgical instrument other than by turning the handle 110.

Those skilled in the art can understand that in the present embodiment, the shaft sleeve 220 and the torsion wheel 230 sleeved outside the rotating shaft 210 are provided, so that the control of the surgical instrument can be realized by using the rotating handle 110 or the rotating torsion wheel 230, and when the surgical instrument is controlled by using the torsion wheel 230, the operator does not need to rotate the wrist, and only needs to stir the torsion wheel 230 with the fingers to rotate, thereby avoiding discomfort for the operator, and facilitating the operator to better complete the surgery.

It should be noted that the shape of the torsion wheel 230 may be a quincuncial shape, an octangular shape, or a star shape, in addition to the hexalobular shape shown in fig. 2, as long as a high protrusion against which a finger can abut is provided on the outer surface of the torsion wheel 230, or only a small protrusion for increasing the friction between the finger and the torsion wheel 230 is provided on the outer surface of the torsion wheel 230. The outer surface of the torsion wheel 230 may be any rugged surface that performs the functions described above.

As shown in fig. 3, in the present embodiment, the outer sidewall of the position-limiting ring 240 is provided with a position-limiting portion 241 protruding to the outer side of the position-limiting ring 240, the inner sidewall of the position-limiting ring 240 is provided with a first abutting portion 242 protruding to the inner side of the position-limiting ring 240, the outer sidewall of the rotating shaft 210 is provided with a second abutting portion 212 protruding to the outer side of the rotating shaft 210, and the stopping member 250 includes a stopping portion 251. Because the limiting ring 240 is fixedly connected with the shaft sleeve 220, when the shaft sleeve 220 is rotated by using the torsion wheel 230, the limiting ring 240 can be driven to rotate together, and when the limiting portion 241 of the limiting ring 240 is abutted against the stopping portion 251, the stopping portion 251 can prevent the limiting ring 240 from continuously moving towards the stopping portion 251, so that the torsion wheel 230 is prevented from continuously rotating in one direction. Taking fig. 3 as an example, at this time, the limiting portion 241 abuts against the lower end of the stopping portion 251, so as to prevent the limiting ring 240 from continuing to rotate clockwise, and when the limiting ring 240 rotates counterclockwise until the limiting portion 241 abuts against the upper end of the lower stopping portion 251, the counterclockwise rotation of the limiting ring 240 is limited.

As can be understood by those skilled in the art, by providing the limiting ring 240 and the stopping member 250, and providing the limiting portion 241 and the stopping portion 251 on the limiting ring 240 and the stopping member 250, respectively, when the limiting portion 241 abuts against the stopping portion 251, the rotation of the limiting ring 240 in one direction is limited, so as to limit the rotation angle of the limiting ring 240, and thus the rotation angle of the torsion wheel 230. Since the surgical instrument is to enter the surgical object during the actual operation, the range of motion of the surgical instrument needs to be limited. If the rotation angle of the torsion wheel 230 is not limited, the range of motion of the surgical instrument may be too large, causing injury to the patient.

It should be noted that, according to the actual operation requirement, a person skilled in the art may enlarge or reduce the size of the limiting portion 241 or the stopping portion 251 in the production process, so as to form the limiting ring 240 and the stopping member 250 of different models, and further limit the degree of rotation of the torsion wheel 230 as required, so as to select different limiting rings 240 and stopping members 250.

With continued reference to fig. 3, in a normal situation, the rotation of the rotating shaft 210 and the rotation of the retainer 240 do not affect each other, but in the rotation of the rotating shaft 210 or in the rotation process of the retainer 240, a situation may occur in which the first abutting portion 242 abuts against the second abutting portion 212, and at the moment when the first abutting portion 242 abuts against the second abutting portion 212, an operator can feel feedback that the rotation is hindered.

It should be noted that the second abutting portion 212 may be integrally formed with the rotating shaft 210, or may be detachably connected to the rotating shaft 210.

As can be understood by those skilled in the art, by providing the first abutting portion 242 and the second abutting portion 212, during the process of rotating the handle 110, the operator can feel feedback at the instant when the first abutting portion 242 and the second abutting portion 212 abut, so as to remind the operator, and at this time, the operator can control the surgical instrument by using the torsion wheel 230 instead, and at the same time, the rotation of the handle 110 is limited.

It should be noted that, according to the actual operation requirement, a person skilled in the art may also adjust the sizes of the first abutting portion 242 and the second abutting portion 212 and the position of the first abutting portion 242 relative to the limiting portion 241 in the production process, so as to form the limiting rings 240 and the second abutting portions 212 of various models, and further select different limiting rings 240 and second abutting portions 212 of different lengths according to the requirement for limiting the degree of rotation of the handle 110.

The stopper 241, the first abutting portion 242, and the second abutting portion 212 may be a protruding block structure as shown in fig. 3, or two protrusions may be provided so that the distance between the two protrusions is the same as the length of the corresponding block structure, which can provide the same effect as the block protrusion.

Further, as can be seen from fig. 3, by making the top of the first abutting portion 242 always contact with the outer wall of the rotating shaft 210 and making the top of the second abutting portion 212 always contact with the inner wall of the retainer ring 240, the relative movement in the radial direction with the retainer ring 4 during the rotation of the rotating shaft 210 is prevented.

As shown in fig. 4, in the present embodiment, the stopping member 250 is further provided with a limiting groove 252, and the limiting portion 241 rotates in the limiting groove 252. The position of the limiting portion 241 can be limited by providing the limiting groove 252, so that the limiting ring 240 can be positioned in the rotation process of the limiting ring 240.

The utility model discloses a second embodiment:

the present embodiment provides a surgical device that includes a lever 100, a control adapter 200, and a power device 300. As shown in fig. 6, the power unit 300 includes an adapter coupling portion 310, and the adapter coupling portion 310 is provided with an engaging portion 311. The control adapter 200 is provided with a catch 260 (shown in fig. 2). The catch 260 may engage with the engagement portion 311 to secure the control adapter 200 to the adapter connection portion.

It can be understood by those skilled in the art that since the operation rod 100 is connected with a surgical instrument at one end and passes through the passage 211 provided in the control adapter 200, blood and tissue carried on the surgical instrument may remain in the rotation shaft 210 to contaminate the control adapter 200 when the operation rod 100 is separated from the control adapter 200 after completion of the operation. By detachably connecting the control adapter 200 to the power unit 300, the control adapter 200 can be removed after the operation is completed, and the control adapter 200 can be handled separately. The connection by the snap-fit connection is easier to install or remove the control adapter 200 than the detachable connection such as bolts and key sheaths, and only the snap fastener 260 needs to be pulled off.

As shown in fig. 5, the control adapter 200 is provided with a sensor (not shown) and a first electrical connector 270. As shown in fig. 6, the power unit 300 is provided with a second electrical connector 312. When the control adapter 200 is installed on the adapter connecting part, the first electric connector 270 and the second electric connector 312 are electrically connected, the sensor can receive the rotation information of the shaft sleeve 220 and the rotating shaft 210 and transmit the rotation information to the power device 300 through the first electric connector 270 and the second electric connector 312, and the power device 300 controls the surgical instrument to perform corresponding actions according to the rotation information.

It should be noted that the first electrical connector 270 and the second electrical connector 312 may employ a coupler or the like capable of signal transmission.

As shown in FIG. 5, the control adapter 200 is further provided with a switch 280, the switch 280 being disposed proximate the handle 110. Switch 280 may control the switching of signals between first electrical connection 270 and second electrical connection 312, and may be located near handle 110 for operator manipulation.

The switch 280 may be a toggle switch as shown in fig. 5, or may be a button or other switch.

The utility model discloses a third embodiment:

although not shown in the drawings, in the present embodiment, unlike the first and second embodiments, the first abutting portion 242 and the second abutting portion 212 are omitted. Since most operators' wrists operate the handle at a more or less limited range of rotation angles, the first abutment 242 and the second abutment 212 may not be provided to alert the operator to prevent the handle from rotating too much.

The fourth embodiment of the present invention:

although not shown in the drawings, in the present embodiment, the retainer ring 240 and the second abutting portion 212 are omitted, unlike the first and second embodiments. This requires the operator to pay special attention to the rotation angle of the torsion wheel, which increases the demands on the operator.

So far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Without deviating from the technical principle of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and also can make equivalent changes or substitutions for related technical features, and any changes, equivalent substitutions, improvements, etc. made within the technical concept and/or technical principle of the present invention will fall within the protection scope of the present invention.
