Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the relevant portions of the related inventions are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

FIG. 1 shows a schematic structural view of one embodiment of an ultrasonic surgical blade of the present application. As shown in fig. 1, the ultrasonic surgical blade may include: an outer tube 101, an inner tube 102, a tool shank 103, and a front end spacer 104 and at least one rear end spacer 105 for spacing the tool shank 103 from the inner tube 102. Wherein, the front end isolation device 104 is sleeved at the front end of the cutter bar 103, and at least one rear end isolation device 105 is sleeved at the rear end of the cutter bar 103 according to a preset distance. The outer tube 101, the inner tube 102 and the knife bar 103 are coaxial, and the inner tube 102 can move along the axial direction and is used for driving the jaws at the front end of the surgical knife to close or open.

In this embodiment, the front end is a portion close to the energy output end of the tool bar 103, and the rear end is a portion far from the energy output end of the tool bar 103. The spacing between each rear end spacer, and between the front end spacer 104 and the rear end spacer, may be arbitrarily set. The front end spacer 104 and the at least one rear end spacer 105 serve to separate the inner tube 102 from the tool shaft 103, avoiding ultrasonic energy losses and mechanical coupling phenomena caused by the contact of the inner tube 102 with the tool shaft 103. Typically, the material of the front end spacer 104 and the at least one rear end spacer 105 is a non-metallic elastic material.

Specifically, in order to communicate between spaces on both sides of each rear-end spacer, the rear-end spacer may be provided in various shapes, for example, with a through hole provided between both ends of the rear-end spacer. Meanwhile, in order to make the space between the isolation portion 1041 and the inner tube 102 not closed, various manners may be adopted, for example, the cross-sectional shape of the isolation portion 1041 is set to a gear shape, an oval shape, or the like.

The sealing portion 1042 is used for dividing the space between the inner tube 102 and the knife bar 103 into two parts, one part of which is communicated with the outside of the surgical knife and the other part of which is isolated from the outside, so that when the external pressure is low during surgery, substances such as gas and liquid can be prevented from entering the interior of the surgical knife from the front end of the ultrasonic knife surgical instrument, the surgical knife can be damaged and the surgery can be influenced, and the cleanness of the surgical knife can be kept.

In some optional implementations of the present embodiment, the maximum outer diameter of the isolation portion 1041 and each of the at least one rear end isolation devices 105 is less than the inner diameter of the inner tube 102. The implementation manner can realize that the space between the isolation part 1041 and the inner tube 102 is not closed, namely, one side of the sealing part 1042 is communicated with the outside, and the other side is isolated from the outside; the space on both sides of the rear end isolation device can be communicated with each other. And the ultrasonic surgical knife can also avoid generating larger friction force when the inner tube 102 and the isolating device do reciprocating motion along the axial direction in the working process, so that the operation effect is prevented from being influenced due to inflexible motion of the inner tube 102 and inflexible opening or closing of the jaws.

In some optional implementations of the present embodiment, the isolation portion 1041 and each of the at least one back end isolation devices 105 include at least one of: a rotary structure and a non-rotary structure. The processing process of the revolving body structure is simple, and the cost of the ultrasonic surgical tool can be reduced. As shown in fig. 1, which illustrates a front end spacer and a rear end spacer of a rotor structure. The non-revolving body structure can increase the space between two sides of the rear end isolating device and improve the effect of space communication. It should be noted that the isolation portion 1041 and the rear end isolation device may be formed separately by a revolving structure or a non-revolving structure, or may include both the revolving structure and the non-revolving structure.

In some alternative implementations of the present embodiment, the non-rotating body structure includes at least one of: the end face is in a gear-shaped structure, and the end face is in a non-circular structure. As shown in fig. 2, the isolation portion 1041 is shown as a schematic diagram of a gear-like structure. As shown in fig. 3, a schematic view of the rear end spacer 105 is shown in a gear-like configuration. The configuration in which the end face is non-circular may be of various shapes, such as oval, rounded rectangle, etc. The non-revolving body structure provided by the implementation mode can reduce the volumes of the front end isolating device 104 and the rear end isolating device under the condition that the isolating effect between the cutter bar 103 and the inner tube 102 is not influenced, and meanwhile, the space can be better communicated with the space, so that the closed space is further prevented from being generated between the inner tube 102 and the cutter bar 103.

In some alternative implementations of the present embodiment, the front end isolation device 104 is a unitary structure and is made of an elastic material. The front end isolation device 104 of the integrated structure can improve the mechanical strength of the front end isolation device 104, avoid damage and prolong the service life.

In some alternative implementations of this embodiment, the isolation portion 1041 and the sealing portion 1042 included in the front end isolation device 104 are separate elements connected together, and the material of the sealing portion 1042 is a non-metal elastic material. The isolation portion 1041 and the sealing portion 1042 may be connected in any manner, such as bonding with an adhesive, or the sealing portion 1042 may be a sealing ring sleeved on the isolation portion 1041. This implementation can reduce the difficulty of processing front end isolating device 104, improve the manufacturing cost of ultrasonic surgical cutter.

The ultrasonic surgical knife tool provided by the above embodiment of the application is through setting up front end isolating device and rear end isolating device on the cutter arbor to the cutter is inside not to include the enclosure space, thereby can avoid when disinfecting ultrasonic surgical knife tool, can not produce non-aseptic space, avoid ultrasonic knife tool in the use, when inner tube and cutter arbor and isolating device relative motion, the risk of the non-aseptic gas leakage that probably produces, avoid causing the risk of operation region infection or pollution.
