Abstract
The utility model relates to a mucoperiosteum annular cutter which belongs to the field of medical machinery and comprises an annular cutter and a connecting rod connected with the annular cutter. The cutter edge of the annular cutter is serrated, and scale marks are made on the side wall of the annular cutter. A cross edge is arranged in the central position of the cutter edge of the annular cutter. A titanium carbide coating is arranged on the cutter edge surface of the annular cutter. The change of the flat cutter edge of the annular cutter into the serrated edge increases the cutting functions of the cutter edge, shortens operation time, and meanwhile avoids gum tissue tear and promotes wound healing. The arrangement of the scale marks on the appearance of the annular cutter can make operators dynamically observe cutting depth while annularly cutting mucoperiosteum tissue. The arrangement of the cross edge is convenient for clearing gum tissue excited. The wear resistance properties of the cutter edge are increased by spraying the titanium carbide coating on the cutter edge.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of non-gingiva mucoperiosteum circular cutter that lobe formula implantation of tooth is planted the incision of gingiva mucoperiosteum, exposure tooth district sclerotin that turns over that is used for.
Background technology
The canine implant operative approach is divided into and turns over lobe and the non-lobe formula dual mode that turns over, and the former need cut growing area gingiva mucoperiosteum tissue, and postoperative is prone to wound oozing of blood, tissue edema, and needs to sew up, take out stitches, and increases patient's pain and treatment time.In recent years, non-ly turn over the main flow art formula that lobe formula operation gradually becomes implant operation, it with " perforating type " (punch) mode directly excise the mucoperiosteum tissue of growing area top, wound is neat, and postoperative does not have oozing of blood, edema, need not to take out stitches, avoid second operation, welcome by the patient.It is circular cutter that this art formula needs a kind of special operating theater instruments, is used for circular resection gingiva mucoperiosteum tissue.Present homemade circular cutter is produced by Oral Planting Science-technology Centre, Ministry of Public Health of Sichuan University (CDIC), though in clinical practice more year surplus in the of 10, but there is tangible design defect, first incision is a flush end, cutting function is relatively poor, consuming time longer during use, and the mucoperiosteum organization edge is irregular, influences the postoperative wound healing; In addition, existing circular cutter does not have scale mark, can't learn the mucoperiosteum tissue thickness of excision, and then the measuring and calculating of the influence plantation nest hole degree of depth.In the material direction of circular cutter, homemade circular cutter is a stainless steel products, and any special handling is not seen on the surface.Though like product is arranged abroad, except that costing an arm and a leg, the improvements of needs is also arranged.
Summary of the invention
The purpose of this utility model just is to overcome the deficiency that prior art exists, and the mucoperiosteum that a kind of cutting power is strong, service efficiency is high circular cutter is provided.
For achieving the above object, this utility model is taked following scheme: a kind of mucoperiosteum circular cutter, include annular cutting knife, be connected the connecting rod of one with annular cutting knife, its difference is: the blade of described annular cutting knife is set to zigzag, in annular cutting knife sidewall portrayal scale mark is arranged.The middle position of annular cutting knife is provided with a chisel edge.The blade surface of described annular cutting knife is provided with titanium carbide coating.The minimum scale unit of described scale mark is 1 millimeter.
This utility model changes the blade of circular cutter into zigzag by flush end, has increased the cutting function of blade, has shortened operating time, has avoided the gingiva tissue lacerated wound simultaneously, promotes wound healing; Make scale mark in the circular cutter appearance, make the patient when the ring cutting mucoperiosteum is organized, can dynamically observe depth of cut; Be provided with a chisel edge, be convenient to remove the gingiva tissue of excision; Blade surface is sprayed with titanium carbide coating, has increased the anti-wear performance of blade.
Description of drawings
Fig. 1 is the cutaway view of this utility model embodiment;
Description of symbols among the figure: 1-connecting rod, 2-chip removal window, 3-chisel edge, 4-serrated knife blade, 5-scale mark.
The specific embodiment
In order to understand this utility model better, be described further below in conjunction with the technical scheme of drawings and Examples utility model, referring to accompanying drawing 1:
Press a kind of mucoperiosteum circular cutter that this utility model is implemented, include annular cutting knife, connecting rod 1 is connected one with annular cutting knife, and the plantation mobile phone provides the rotary power of cutting for annular cutting knife by the bar 1 that is clamped and connected.The blade of annular cutting knife is a serrated knife blade 4, to increase the cutting function of blade, improves mucoperiosteum ring cutting efficient, also avoids the gingiva tissue lacerated wound, reduces and organizes hemorrhage and edema, promotes wound healing.Annular cutting knife sidewall is offered chip removal window 2, is convenient to discharge the tissue of cutting.With laser portrayal minimum scale being arranged at annular cutting knife sidewall is 1 millimeter scale mark 5, and scale mark 5 and annular slitter shaft line parallel are used for the labelling depth of cut, and then the measuring and calculating preparation implantation body required brill bone degree of depth in nest hole.Annular cutting knife middle position is provided with a chisel edge 3, is convenient to remove the gingiva tissue of excision.The blade surface of annular cutting knife is sprayed with Tic (titanium carbide) coating, increases the anti-wear performance of blade, increases the service life.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of this utility model certainly with this, and therefore the equivalence of being done according to this utility model claim changes, and still belongs to protection domain of the present utility model.
Claims (4)
1. mucoperiosteum circular cutter includes annular cutting knife, is connected the connecting rod of one with annular cutting knife, and it is characterized in that: the blade of described annular cutting knife is set to zigzag, in annular cutting knife sidewall portrayal scale mark is arranged.
