As shown in fig. 1 to 8, the present invention provides a protection device (hereinafter, simply referred to as a protection device) for an energy apparatus, which is sleeved on a rotating part, a supporting part and a part of an insulation part of the energy apparatus, and has an effect of protecting the energy apparatus, and has an effect of insulating an area of the energy apparatus which does not need to contact a human body, so as to prevent the energy apparatus from causing electric shock injury to human tissues due to high-frequency current at the area of the energy apparatus which does not need to contact the human body.
In some embodiments, the energy protection device comprises a liner 1 and a protection piece 2 which are coaxially arranged, wherein the liner 1 and the protection piece 2 are in a cylindrical structure, the liner 1 is embedded in the protection piece 2, the liner 1 can cover a rotating part, a supporting part and a part of insulating part of an energy instrument, and one end of the protection piece 2 is provided with an opening through which the energy instrument passes; the lining 1 is made of an insulating first material, the material of the protecting piece 2 is made of an insulating second material, and the strength of the first material is larger than that of the second material.
The inner liner 1 can cover the rotating part, the supporting part and part of the insulating part of the energy instrument, so that the protection device has better tear resistance at the rotating part, the supporting part and the part of the insulating part of the energy instrument. The inner liner 1 is embedded in the protection piece 2, and the inner liner can cover the rotating part, the supporting part and part of the insulation part of the energy instrument, namely, the inner liner 1 penetrates through the whole protection piece 2 in the length direction, so that the uniformity of a product of the protection device in the length direction is good, the service life is prolonged, and the parts of the protection device have better tear resistance. The material of the protection member 2 is an insulating second material, and the strength of the first material is greater than that of the second material. The liner 1 provides strength support to the protector 2 throughout the installation and removal to prevent the protector 2 from curling at the insulation portion, facilitating the installation and removal. And the lining 1 enhances the strength of the protective device everywhere, and prevents the protective device from being punctured by other surgical tools in the surgical process.
The forceps body of the energy instrument is arranged at the far end, and the insulation part is arranged at the near end. Wherein the distal end is the end farther from the operator. The two ends of the lining 1 are respectively provided with a first opening 11 and a second opening, the second opening is a mounting opening, the energy instrument is convenient to penetrate, and the first opening 11 is used for allowing the clamp body to penetrate. The aperture of the first opening 11 is smaller than that of the second opening, so that after the forceps body passes out, the protecting device can be tightly wrapped at the position of the energy instrument connected with the forceps body, and the protecting range of the protecting device on the energy instrument is better. Correspondingly, the liner 1 is embedded in the protection piece 2, and a third opening 21 and a fourth opening are correspondingly formed at two ends of the protection piece 2 respectively. The fourth opening corresponds to the second opening for the liner 1 to penetrate, and the third opening 21 corresponds to the first opening 11 for the liner 1 to penetrate.
Specifically, the liner 1 is made of a first material, and the first material is glass fiber or thermoplastic polyurethane elastomer rubber, and in other embodiments, the first material may be other medical composite materials such as polyurethane, but not limited thereto; the material of protection piece 2 is the second material, and the second material is the silica gel, and the feel of silica gel is better, and the doctor is more comfortable when holding silica gel or silica gel contact patient's body feel. The strength of the glass fiber or the thermoplastic polyurethane elastomer rubber is larger than that of the silica gel, and the lining 1 provides supporting strength for the protecting piece 2, so that the integral strength of the protecting device formed by the lining 1 and the protecting piece 2 together is enhanced, and the protecting device is prevented from being punctured during use.
Since the rotation part of the energy apparatus and the clamp body are deformed when they move, the inner liner 1 is required to have toughness to cope with the deformation while ensuring the strength of the inner liner 1. In order to enhance the toughness of the inner liner 1, the side wall of the inner liner 1 is of a hollow structure, and the protection piece 2 and the inner liner 1 are of a co-injection integrated structure. For ease of processing, the thickness of the liner 1 after molding is 1/2-1/3 of the thickness of the whole energy mechanical protection device. The co-injection molding mode is low in cost, the preparation of the lining 1 is finished firstly, then the lining 1 is put into a mold, and then the silica gel is poured to form the protection device.
Because the motion modes and the amplitudes of the motion parts of the energy machinery are different when the energy machinery works, the requirements on the strength and the toughness of the protection device are also different, and therefore, the structure of the lining 1 is required to be changed according to the use requirement in the design process so as to change the strength and the toughness of the protection device, and the method comprises the following conditions:
in some embodiments, the planar expanded view of liner 1 is grid-like.
In a first implementation of the present embodiment, as shown in fig. 3, the liner 1 comprises a tubular member, the side wall of which is provided with a plurality of radially through-going meshes 12. Specifically, the mesh 12 is round or square, and may be diamond-shaped. For the convenience of processing, a plurality of meshes 12 are uniformly distributed on the side wall of the lining 1, and a plurality of meshes 12 are regularly arranged. The arrangement of the meshes 12 can increase the toughness of the lining 1, and is convenient for the deformation of the lining 1. To better accommodate bending of the energy device, in use, the direction of alignment of the single row of mesh openings 12 is at an angle to the axis of the energy device, a line parallel to the axis of the energy device passing through at least one of the mesh openings 12.
In the second embodiment of the present embodiment, as shown in fig. 4 and 5, the mesh 12 is a polygon with five or more sides, and the sizes of the apertures of the polygonal mesh 12 can be reasonably arranged according to the difference in strength and toughness required for the liner 1. Specifically, the liner 1 shown in fig. 4 has smaller proportion of the mesh 12 size to the surface area of the tubular member than the liner 1 shown in fig. 5, and the resulting liner 1 has greater strength and is suitable for energy devices with greater driving force; accordingly, the liner 1 shown in fig. 5 has a larger proportion of the mesh 12 size to the surface area of the tubular member than the liner 1 shown in fig. 4, and the liner 1 has a stronger toughness and is suitable for use in energy devices with greater flexibility in the location of movement. Further, as shown in fig. 5, in order to make the first opening 11 of the liner 1 have stronger toughness to adapt to the movement of the forceps body of the energy apparatus, the outer contour line near the end of the liner 1 provided with the first opening 11 is also provided with a mesh 12, in other words, the liner 1 includes a supporting body with a cylindrical structure, the first opening 11 and the second opening are respectively provided at two ends of the supporting body, a plurality of stop parts are provided at the first opening 11 of the supporting body, and the plurality of stop parts are arranged around the axis of the supporting body and extend towards the axis of the supporting body and the direction away from the second opening.
In a third implementation of this embodiment, as shown in fig. 6, the liner 1 includes a plurality of annular members 13, the plurality of annular members 13 are uniformly distributed around the main axis of the energy apparatus and are connected end to end in sequence to form annular monomers, and the plurality of annular monomers are sequentially arranged along the main axis and are connected between every two adjacent annular members 13. Adjacent ring members 13 may be connected by a connecting member 16. The arrangement of the connecting piece 16 makes the toughness of the lining 1 moderate and the strength higher.
In a fourth implementation of the present embodiment, as shown in fig. 7, the liner 1 comprises at least one support strip 14 and a number of connection strips 15, both support strips 14 extending along the main axis of the energy instrument, the connection strips 15 surrounding the main axis into connection rings, the number of connection rings being arranged at intervals along the main axis and being connected to both support strips 14. The liner 1 with the structure can adapt to bending action of an energy instrument. Specifically, the connecting ring is wavy. The wavy connecting ring enables the lining 1 to be stretched along the wave setting direction, i.e. the lining 1 can adapt to the change of the diameter of the energy appliance, thereby enabling the lining 1 to have stronger toughness. Further, to accommodate more flexible energy mechanisms, corrugations are provided in multiple directions of the connecting strip 15 to improve the toughness of the liner 1. Illustratively, the connecting strip 15 forms waves in the axial direction of the energy apparatus and waves in the radial direction of the energy apparatus. Still another example is that the connecting strip 15 is of a helical configuration, i.e. the helical connecting strip 15 is looped around the axis of the energy instrument and connected to the support strip 14.
Of the inner liners 1 of the third and fourth embodiments and the inner liner 1 including the plurality of annular members 13, the inner liner 1 of the fourth embodiment has a high toughness, and is suitable for energy devices with high flexibility at the movement position, and the inner liner 1 of the third embodiment has a high strength, and is suitable for energy devices with high driving force.
In the fifth embodiment of the present embodiment, as shown in fig. 8, the liner 1 is formed by spirally winding a wire, and the structure has strong toughness, and is suitable for an energy apparatus with high flexibility and small driving force at a movement position. In some embodiments, the toughness of liner 1 is further increased by designing corrugations on the coiled wire.
In some embodiments, liner 1 is woven in a plain weave.
In some embodiments, liner 1 is woven in a twill fashion.
In some embodiments, the liner 1 is woven in a satin weave.
Among the three knitting modes of the lining 1, the toughness of the lining 1 knitted by twill is higher than that of the lining 1 knitted by plain weave; the inner lining 1 woven by satin can make the inner lining wall of the inner lining 1 as thin as possible on the premise of ensuring the toughness, thereby being beneficial to saving raw materials and cost.
Further, the liner 1 includes at least two mesh portions, which are sequentially connected in the length direction, and each mesh portion has a different structure. The design of the liner 1 can be adapted to the different energy machines required for toughness and strength of the protection device, and the various liner 1 structures can be freely combined to form one desired liner 1. Illustratively, the two-section mesh portion is defined as a first mesh portion and a second mesh portion, the first mesh portion is sleeved on the rotating portion and the supporting portion, the second mesh portion is sleeved on the insulating portion, and the toughness of the first bending portion is greater than that of the second mesh portion.
