The specific meaning of the above terms in the present application can be understood by those skilled in the art as the case may be.

The first embodiment of the present application:

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. Control adapter 200 includes a housing (not shown), a mounting portion 210, an instrument channel portion 220, a stop collar 230, and a stop member 240. Instrument channel portion 220 includes a shaft 221, a sleeve 222, and a torsion wheel 223 as a rotating member. As shown in fig. 2, the shaft 221 is provided with a passage 2211. As shown in fig. 1, the operating rod 100 passes through the passage 2211 and is fixedly connected to the rotating shaft 221 via the handle 110. The shaft sleeve 222 is sleeved on the outer side of the rotating shaft 221, and the torsion wheel 223 is also sleeved on the outer side of the rotating shaft 221 and fixedly connected with the shaft sleeve 222. The retainer 230 is also disposed on the outer side of the shaft 221 and is fixed to the shaft sleeve 222.

It should be noted that the torsion wheel 223 is only one kind of rotary structure, and the rotary structure may be a plurality of rotary thin rods fixed on the bushing 222. Meanwhile, the torsion wheel 223 and the shaft sleeve 222 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. In this case, the operator can operate the surgical instrument by rotating the torsion wheel 223, thereby controlling the surgical instrument by means other than rotating the handle 110.

Those skilled in the art can understand that, in the embodiment, the shaft sleeve 222 and the torsion wheel 223 sleeved outside the rotating shaft 221 are arranged, so that the control of the surgical instrument can be realized by using the rotating handle 110 or the rotating torsion wheel 223, and when the surgical instrument is controlled by using the torsion wheel 223, an operator does not need to rotate the wrist, and only needs to stir the torsion wheel 223 by fingers to rotate, thereby avoiding discomfort of the operator, and being beneficial to the operator to better complete the surgery.

It should be noted that the shape of the torsion bar 223 may be a quincuncial shape, an octagonal 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 bar 223, or only a small protrusion for increasing the friction force between the finger and the torsion bar 223 is provided on the outer surface of the torsion bar 223. The outer surface of the torsion wheel 223 may be any rugged surface that performs the above-described functions.

As shown in fig. 3, in the present embodiment, the outer sidewall of the position-limiting ring 230 is provided with a position-limiting portion 231 protruding to the outer side of the position-limiting ring 230, the inner sidewall of the position-limiting ring 230 is provided with a first abutting portion 232 protruding to the inner side of the position-limiting ring 230, the outer sidewall of the rotating shaft 221 is provided with a second abutting portion 2212 protruding to the outer side of the rotating shaft 221, and the stopping member 240 includes a stopping portion 241. Because the limiting ring 230 is fixedly connected with the shaft sleeve 222, when the shaft sleeve 222 is rotated by the torsion wheel 223, the limiting ring 230 can be driven to rotate together, and when the limiting part 231 of the limiting ring 230 is abutted against the stopping part 241, the stopping part 241 can prevent the limiting ring 230 from continuously moving towards the stopping part 241, so that the torsion wheel 223 is prevented from continuously rotating in one direction. Taking fig. 3 as an example, at this time, the limiting portion 231 abuts against the lower end of the stopping portion 241, so as to prevent the limiting ring 230 from continuing to rotate clockwise, and when the limiting ring 230 rotates counterclockwise until the limiting portion 231 abuts against the upper end of the lower stopping portion 241, the counterclockwise rotation of the limiting ring 230 is limited.

As can be understood by those skilled in the art, by providing the limiting ring 230 and the stopping member 240, and providing the limiting portion 231 and the stopping portion 241 on the limiting ring 230 and the stopping member 240 respectively, when the limiting portion 231 abuts against the stopping portion 241, the rotation of the limiting ring 230 in one direction is limited, so as to limit the rotation angle of the limiting ring 230, and thus the rotation angle of the torsion wheel 223. 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 223 is not limited, the range of motion of the surgical instrument is too large, and the patient may be injured.

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 231 or the stopping portion 241 in the production process, so as to form different types of limiting rings 230 and stopping members 240, and further limit the degree of rotation of the torsion wheel 223 according to the requirement, so as to select different limiting rings 230 and stopping members 240.

With continued reference to fig. 3, in a normal case, the rotation of the rotating shaft 221 and the rotation of the retainer ring 230 do not affect each other, but in the rotation of the rotating shaft 221 or in the rotation of the retainer ring 230, there may be a case where the first abutting portion 232 abuts against the second abutting portion 2212, and at the moment when the first abutting portion 232 abuts against the second abutting portion 2212, an operator can feel feedback that the rotation is hindered.

The second abutting portion 2212 may be integrally formed with the rotating shaft 221, or may be detachably connected to the rotating shaft 221.

As can be understood by those skilled in the art, by providing the first abutting portion 232 and the second abutting portion 2212, during the process of rotating the handle 110, the operator can feel feedback at the instant when the first abutting portion 232 and the second abutting portion 2212 abut against each other, so as to remind the operator, and at this time, the operator can use the torsion wheel 223 to control the surgical instrument, 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 232 and the second abutting portion 2212 and the position of the first abutting portion 232 relative to the limiting portion 231 in the production process, so as to form the limiting rings 230 and the second abutting portions 2212 of various models, and further select different limiting rings 230 and second abutting portions 2212 of different lengths according to the requirement for limiting the degree of rotation of the handle 110.

In addition, the stopper 231, the first abutting portion 232 and the second abutting portion 2212 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 achieve the same effect as the block protrusion.

Further, as can be seen from fig. 3, by making the top of the first abutting portion 232 always contact with the outer wall of the rotating shaft 221, the top of the second abutting portion 2212 always contacts with the inner wall of the retainer ring 230, so that the relative movement in the radial direction with the retainer ring 4 during the rotation of the rotating shaft 221 is prevented.

As shown in fig. 4, in the present embodiment, the stopping member 240 is further provided with a limiting groove 242, and the limiting portion 231 rotates in the limiting groove 242. The position of the stopper 231 can be restricted by providing the stopper groove 242, so that the stopper ring 230 can be positioned during the rotation of the stopper ring 230.

Second embodiment of the present application:

the present embodiment provides a surgical device that includes a lever 100, a control adapter 200, and a power device 300. The control adapter 200 is removably coupled to the power unit 300.

It can be understood by those skilled in the art that since the operation rod 100 is connected to a surgical instrument at one end thereof and passes through the passage 2211 provided in the control adapter 200, blood and tissue carried on the surgical instrument may remain in the rotation shaft 221 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.

Specifically, as shown in fig. 5, the mounting portion 210 is provided with a receiving cavity 260, as shown in fig. 7, the power device 300 includes an adapter connecting portion 310, and the receiving cavity 260 and the adapter connecting portion 310 are matched in size, so that when assembled, the receiving cavity 260 can wrap the adapter connecting portion 310. As shown in fig. 5 and 6, the mounting portion 210 is further provided with a catch 250, and the adapter connecting portion 310 is provided with an engaging portion 311. The catch 250 may engage with the engaging portion 311 to secure the control adapter 200 to the adapter coupling portion.

It will be appreciated by those skilled in the art that the connection between the control adapter 200 and the adapter connector 310 is made more secure by providing the receiving cavity 260 and wrapping the adapter connector 310 to prevent the control adapter 200 from moving laterally, longitudinally, and vertically downward relative to the adapter connector 310. Meanwhile, by providing the catch 250, the control adapter 200 is prevented from moving in the vertical direction with respect to the adapter connecting portion 310, and the detachable connection between the control adapter 200 and the adapter connecting portion 310 is achieved.

In addition, by providing the receiving cavity 260, on the basis of making the connection between the control adaptor 200 and the adaptor connecting portion 310 more secure, the instrument channel portion 220 can be placed side by side with the adaptor connecting portion 310, that is, the instrument channel portion 220 can be at the same level with the adaptor connecting portion 310, and when the operation rod 100 extends and continues to extend in the direction of the power device 300, compared to the other relative positions where the instrument channel portion 220 is located at the adaptor connecting portion 310, the above arrangement can reduce the bending of the operation rod 100 during the extending process.

It should be noted that the snap connection is only one preferable mode for achieving detachable connection between the control adapter 200 and the adapter connection portion 310, and the control adapter 200 is easier to attach or detach than detachable connection modes such as a bolt and a key sheath, and only the snap 250 needs to be pulled off.

As shown in fig. 6, the control adapter 200 is provided with a sensor (not shown) and a first electrical connector 270. As shown in fig. 7, the power unit 300 is provided with a second electrical connection 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 222 and the rotating shaft 221 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. 6, 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 shown in fig. 6, or may be a button or other switch.

Third embodiment of the present application:

although not shown in the drawings, in the present embodiment, unlike the first and second embodiments, the first and second abutting

portions

232 and 2212 are omitted. Since most operators' wrists operate the handle at a more or less limited range of rotation angles, the first and

second abutments

232 and 2212 may not be provided to alert the operator to prevent the handle from rotating too much.

Fourth embodiment of the present application:

although not shown in the drawings, in the present embodiment, the spacing collar 230 and the second abutting portion 2212 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 solutions of the present application have been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of protection of the present application is not limited to these specific embodiments. The technical solutions in the above embodiments can be split and combined, and equivalent changes or substitutions can be made on related technical features by those skilled in the art without departing from the technical principles of the present application, and any changes, equivalents, improvements, and the like made within the technical concept and/or technical principles of the present application will fall within the protection scope of the present application.
