embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are merely intended to more clearly illustrate the invention, i.e., to provide a more thorough understanding of the invention, and are given numerous specific details. It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these specific details. In these examples, some features that are well known in the art have not been described in order to avoid obscuring the present invention.
It is understood that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, which are intended as examples only and should not be construed as limiting the scope of the invention.
In addition, it is to be noted that technical terms or scientific terms used herein should have the ordinary meaning as understood by those skilled in the art to which the present invention belongs, unless otherwise specified.
The invention is explained in further detail below with reference to the drawings.
Referring to fig. 1 to 5, the ultrasonic scalpel connecting handle includes a handle body a, a cable B connecting the ultrasonic main body plug C and the plug C with the handle body, and an ultrasonic transducer (not shown) and an electrode assembly D contacting with an ultrasonic scalpel head (not shown) are disposed in the handle body a. The handle body is generally in the shape of a shuttle, and the part connected with the ultrasonic cutter head (not shown) is a connecting handle 1.
The end part of the connecting handle 1 is provided with a connecting sleeve 2 which is annularly arranged in a ring groove 11 on the outer surface of the end part of the connecting handle at the inner side of the tail end and can independently rotate and is connected with an ultrasonic cutter head (not shown); the outer side of the front end port of the connecting sleeve 2 is provided with a screw thread for connecting an electrode connecting installation port at the tail end of an ultrasonic cutter head (not shown), the rear part of the connecting sleeve 2 is a part clamped in the annular groove 11, and a convex surface 21 which is more convex than the other parts of the connecting sleeve 2 in appearance is arranged on the outer surface of the part, so that a finger can be conveniently pressed on the convex surface to exert force, and the sleeve body of the connecting sleeve 2 can rotate. In some embodiments, the convex surface 21 may also be provided with anti-slip threads.
Continuing mutual authentication and referring to fig. 2 and 3, the part of 2 tail end cards of adapter sleeve in annular 11 is equipped with at least one rotary column hole 22 along the sleeve axle axial, corresponds rotary column hole 22 and is in be equipped with on the cell wall 12 of annular 11 and run through the locating hole 13 of cell wall along the axial, correspond locating hole 13 and put a interlock ring lid 3 that is equipped with reference column 31 in the cell wall outside cover of annular 11 of keeping away from adapter sleeve 2, reference column 31 passes behind locating hole 13 and sinks in rotary column hole 22 to realize adapter sleeve 2 and connection handle 1 synchronous revolution by the rotation of interlock ring lid 3.
In this embodiment, the screw thread on the outer portion of the front end of the connection sleeve 2 is pressed into the electrode connection mounting opening at the tail end of the ultrasonic scalpel head (not shown), and then the connection handle 1 and the ultrasonic scalpel head can be connected only by rotating the connection sleeve 2 alone.
Based on the installation standard, the electrode assembly D in the ultrasonic blade connection handle needs to be firmly clamped and connected with the electrode in the ultrasonic blade head (not shown), so that the interlocking ring cover 3 is pressed towards the connecting sleeve 2 immediately before the connecting sleeve 2 rotates tightly.
The positioning column 31 of the linkage ring cover 3 passes through the groove wall 12 of the ring groove 11 and falls into the rotary column hole 22 of the connecting sleeve 2, at the moment, the connecting sleeve 2 rotates and synchronously drives the connecting handle 1 to rotate, and then the buckling connection of the internal electrodes of the connecting sleeve 2 and the connecting handle is realized. Under this condition, the whole ultrasonic knife connecting handle rotation number of turns can be completed in one turn usually, and the cable at the tail end of the ultrasonic knife connecting handle basically cannot be wound and twisted, so that excessive connecting trouble cannot be brought.
Continuing to refer to fig. 4, in the implementation of the present embodiment, the connection sleeve 2 and the linking ring cover 3 are installed on the outer surface of the connection handle 1 in order to realize the connection of the ultrasonic scalpel to the handle. The handle body A1 part installed on the linkage ring cover 3 can be connected with the handle body A2 part through the bolt connection, so that after the handle body A1 part is separated from the handle body A2 part, the linkage sleeve 2 and the linkage ring cover 3 can be sleeved on the tail end of the handle body A1 part, and then the handle body A1 part is connected with the handle body A2 part through the bolt connection. Separation of the handle body a1 portion from the handle body a2 portion is merely a separation of the body shell and does not affect the integrity of the inner electrode assembly D within the handle body a.
With continuing reference to fig. 4 and 5, as a further improvement to the embodiment of the present invention, a clip 32 extends from an end of the positioning post 31 to one side, and a groove edge 23 for the clip to clip into is provided along a corresponding side hole of the screw post hole 22 corresponding to the clip 32.
In this embodiment, the interlocking ring cover 3 is disposed on the groove wall 12 of the annular groove 11 and falls into the stud hole 22 of the connecting sleeve 2, and then the interlocking ring cover 3 rotates to make the clamping foot 32 of the positioning column 31 clamped into the groove edge 23 of the stud hole 22, so that the interlocking ring cover 3 realizes the locking of the connecting handle 1 and the connecting sleeve 2.
In practice, the locking legs 32 can extend to both sides, and the groove 23 of the stud hole 22 can also extend to both sides. Therefore, regardless of the rotating direction, the connecting sleeve 2 and the connecting handle 1 can be locked, and the connecting handle 1 can be driven to be further screwed in the electrode connecting installation opening of the ultrasonic scalpel head (not shown) when the connecting sleeve 2 is further rotated.
With reference to fig. 2, as an improvement of the embodiment of the present invention, the end surface of the linking ring cover 3 is a table 34 protruding in a ring shape and having a ring-shaped groove 33 in the middle, and a spring 4 is disposed in the ring-shaped groove 33; the positioning column 31 is disposed above a groove wall on one side of the annular groove 33.
In this embodiment, the spring 4 can prevent the interlocking ring cover 3 from entering the rotary hole 22 by mistake after exiting the positioning hole 13 when the connecting sleeve 2 rotates.
Further, as an improvement of the embodiment of the present invention, the upper surface of the groove wall of the annular groove 33 close to the center direction of the interlocking ring cover 3 constitutes a groove wall connected with one side of the groove 11 formed on the outer surface of the end portion of the handle 1.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
