Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The core of the invention is to provide a therapeutic appliance of two-in-one type appliance, which can realize the switching use of the two appliances, is simple to operate and convenient to use, and has higher flexibility.
Referring to fig. 1 to 11, the present application provides a therapeutic apparatus of a two-in-one instrument, which is mainly used for detecting therapeutic processes such as an endoscope, wherein a proximal end refers to an operation side of the therapeutic apparatus, a distal end refers to a side close to an affected part, corresponding proximal ends of the components are all sides of the components close to the operation side, and distal ends of the components are all sides of the components close to the affected part.
The therapeutic apparatus comprises a first instrument 5 and a second instrument 6 which can stretch and retract along the axial direction, and a handle capable of operating the first instrument 5 and the second instrument 6, wherein the handle comprises a main body part 1, an elastic piece 7, a handle sliding block 2, a first sliding block 3 and a second sliding block 4.
The handle slide block 2, the first slide block 3 and the second slide block 4 are all arranged on the main body part 1 in a sliding way along the axial direction, the first slide block 3 is connected with the first instrument 5 through a first operation wire 5a, and the second slide block 4 is connected with the second instrument 6 through a second operation wire 6 a. The first operation wire 5a and the second operation wire 6a should be hard operation wires, and push and pull operations can be performed.
The first instrument 5 and the second instrument 6 are therapeutic or detecting instruments in the present application, wherein the first instrument 5 can be used to perform its function when extended distally, and can be moved to its operative position when the second instrument 6 is moved proximally, thereby performing the operation, or wherein the third instrument 10 at the distal end is exposed due to the movement of the second instrument 6 proximally, thereby performing the operation of the third instrument 10.
In the initial state, the handle slider 2 is located in the middle of the main body 1 (i.e., in the initial position, refer to fig. 1), the first slider 3 and the second slider 4 are located in the respective initial positions, and the first instrument 5 and the second instrument 6 are located at the distal ends. Neither the first instrument 5 nor the second instrument 6 is in the working position.
Movement of the handle slider 2 in the axial distal direction may be used to urge the first operating wire 5a to move distally so as to urge the first slider 5 connected thereto to move distally, and movement of the handle slider 2 in the axial proximal direction may be used to urge the second operating wire 6a to move proximally so as to urge the second slider 6 connected thereto to move proximally.
Specifically, when the handle slider 2 pushes the first slider 3 distally, the first slider 3 is connected to the first operating wire 5a, so that the first operating wire 5a moves distally, and the second slider 4 is abutted by the body portion 1 to limit the movement thereof distally in the process of pushing the first instrument 5 to the first instrument working position, and the elastic member 7 limits the movement of the second slider 3 proximally. In this state, the second slider 4 cannot move distally due to the abutting action, and cannot move proximally freely due to the elastic force of the elastic member 7, so that the second slider can be held at the abutting position with the main body 1, and the stability of the position thereof can be ensured.
In this state, the elastic member 7 also has an elastic force acting on the first slider 3 to drive the first slider 3 to return when the pushing force of the handle slider 2 is canceled.
At this time, if the handle slider 2 moves proximally to return to the middle position, the first slider 3 will be subjected to the elastic force of the elastic member 7, and reset to the initial position, so as to drive the first operation wire 5a to reset to the initial position, and further drive the first instrument 5 to move from the first instrument working position to the corresponding initial position in the proximal direction.
When the handle slider 2 pushes the second slider 4 proximally, the second slider 4 is connected to the second operation wire 6a, so that the second operation wire 6a moves proximally, and in the process of pushing the second instrument 6 proximally to the second instrument working position, the first slider 3 is abutted by the main body 1 to limit the proximal movement thereof, and the elastic member 7 limits the distal movement of the first slider 4. In this state, the first slider 3 cannot move proximally due to the abutting action, and cannot move distally freely due to the elastic force of the elastic member 7, so that the first slider can be held at the abutting position with the main body portion, and the position can be stabilized.
In this state, the elastic member 7 also has an elastic force acting on the second slider 4 to drive the second slider 4 to return when the pushing force of the handle slider 2 is canceled.
At this time, if the handle slider 2 moves to the distal end to return to the middle position, the second slider 4 is subjected to the elastic force of the elastic member 7, and moves to the initial position in a resetting manner, so as to drive the second operation wire 6a to return to the initial position, thereby driving the second instrument 6 to move from the second instrument working position to the corresponding initial position in a distal end.
In the use process of the structure, if the first instrument 5 is needed to be used, the control handle sliding block 2 moves distally, so that the first instrument 5 can be extended and is in the working position, the second instrument 6 can not be extended outwards, and the second instrument 6 is in a stable state. After the first apparatus 5 is used, the handle slider 2 can be controlled to reset (move towards the proximal end) to drive the first apparatus 5 to reset.
If the second instrument 6 is to be used, the handle slider 2 is controlled to move proximally, so that the second instrument 6 moves proximally a certain distance and is in its working position, without causing the first instrument 5 to extend outwards, and so that the first instrument 5 is in a stable state. After the second apparatus 6 is used, the handle sliding block 2 can be controlled to reset to drive the second apparatus 6 to reset.
The operation mode is simple, the handle sliding block 2 can drive the segmentation and time-sharing work of two instruments, the two directions of the handle sliding block 2 are moved to respectively realize the work of different instruments, the operation of instrument switching is simpler, the action is coherent, the use is more convenient and reliable, and the probability of switching errors in operation can be reduced.

When the handle slide block 2 starts to move towards any direction, the corresponding slide block is driven to move, so that the movement of the instrument towards the working position is realized, and the work efficiency of the handle slide block 2 is maximized.
In another embodiment, the width between the proximal end and the distal end of the handle slider 2 is smaller than the distance between the first limiting surface 11 and the second limiting surface 12, so that when the handle slider 2 is located at the axial middle position, the distal end side and the proximal end side of the handle slider 2 are respectively spaced from the first slider 3 and the second slider 4.
In this embodiment, before the handle slider 2 is pushed to move in the distal or proximal direction, there is a section where the handle is not operated, and the corresponding slider is relatively delayed to start moving, so that the switching of the instrument due to the misoperation of the handle slider 2 can be avoided.
Optionally, an elastic structure is arranged on the handle sliding block 2, so that the handle sliding block 2 is attached to one of the first sliding block 3 and the second sliding block 4 with a gap when not operated, or an elastic structure is arranged, so that the handle sliding block 2 keeps a certain gap with the first sliding block 3 and the second sliding block 4 when not operated.
In any of the above embodiments, the first instrument 5 may be a first electrode.
In any of the above embodiments, the second instrument 6 may be a second electrode or sheath.
In addition, the present therapeutic device may further comprise a third axially fixed device 10, which may be a third electrode.
For example, the first instrument 5 may be a rod-shaped or needle-shaped structure (I-shaped knife) which can be extended distally by pushing the first slider 3 to perform marking, cutting and the like, the second instrument 6 may be a sheath tube which can be moved proximally by pushing the second slider 4 to retract proximally so that the third instrument 10 at the distal end is exposed to the distal end of the sheath tube to start the operation of the third instrument 10, and the third instrument 10 may be an enlarged second electrode (O-shaped knife) which is penetrated by the first electrode to perform hemostasis, cutting and the like when the sheath tube is exposed.
The first electrode and the third electrode may be electrodes of other shapes to form different multifunctional electric knives, and the structural relationship between the two electrodes is not limited to penetrating through the sleeve, and may be parallel arrangement.
Referring to fig. 9, 10 and 11, fig. 9 is a cross-sectional view of the distal end position in the initial state, fig. 10 is a cross-sectional view of the distal end position in the first instrument operation state, and fig. 11 is a cross-sectional view of the distal end position in the second instrument operation state.

Referring to fig. 9, when in the initial state, the handle slider 2 is located in the middle, and the first and second instruments 5 and 6 are both located in the non-working positions;
Referring to fig. 10, the handle slider 2 pushes the first electrode distally, pushing it out of the sheath, and the second instrument 6 remains in place;
Referring to fig. 11, the handle slider 2 is moved proximally to reposition the first electrode, and continued movement of the handle slider 2 pushes the sheath proximally to retract the sheath to expose the third instrument 10.
In the initial state, the third electrode may be disposed further distally than the first electrode, which may extend a longer length than the sheath is retracted. Thus, when the sheath tube is retracted, the third electrode is exposed and the first electrode is not exposed, so that an operator can safely and singly use the third electrode for operation. The setting of the telescopic lengths can be realized by giving different sliding spaces (lengths) to the sliding blocks at the handle end, and the adaptive design can be made according to actual needs.
Of course, the above instruments may be combined in other ways to achieve different surgical functions, and are not limited to the electrode instrument, for example, the second instrument 6 may be a string hook, etc. to achieve a surgical operation such as suturing. The above description of several cases is by way of example only and is not intended as a limitation in the practice of the present invention.
