ー种皮肤活检环钻 Species ー skin biopsy trephine

技术领域 FIELD

[0001] 本发明涉及医疗器械技术领域,尤其涉及一种用于采集皮肤组织病理标本的エ具。 [0001] The present invention relates to the technical field of medical devices, and particularly to a method for collecting Ester with skin histopathology specimens.

背景技术 Background technique

[0002] 随着环境的恶化,以及生活、工作中接触到电子产品辐射越来越多,导致近年来皮肤病的病发率较高。 [0002] With the deterioration of the environment, as well as life, work, come into contact with more and more electronic product radiation, resulting in a higher incidence rates of skin diseases in recent years. 在皮肤病的诊断和治疗过程中,皮肤组织病理诊断具有重要的价值,目前病理标本采集的方法主要有手术切取法、环钻法和削切法,其中,环钻法应用较为普遍,特别适用于较小的早期皮损或局限于表浅处或手术切取困难者。 In the diagnosis and treatment of skin diseases, skin tissue pathological diagnosis has important value, the current method of pathological specimens collected mainly surgical borrowing, drilling method and the cutting of the ring method, wherein the ring-drill method more general, especially for for small lesions or early limited to superficial or surgical cut at difficulties. 角膜环钻是环钻法的实施工具,其前端有环切刀,在将环钻钻到患者皮下组织后,取下环钻,用镊子夹住标本,用刀子或剪子在脂肪层剪下标本,最終完成病理取样;这一操作过程较为复杂,容易挤压破坏标本或因标本过厚、过大,反复环切导致标本切缘不锐利整齐,切面形状欠规整等各顶缺点,影响病理观察結果。 Corneal trephine tool is a trephine method embodiment, cutter ring front end thereof, in a patient after the subcutaneous tissue trephine drill, a trephine is removed, forceps specimens, specimens cut with a knife or scissors fat layer the eventual pathological samples; this operation is complicated, easy to squeeze or damage the specimen by specimen too thick, too large, resulting in repeated circumcision specimen edge is not sharp neat, under each of the top cross-sectional shapes other shortcomings structured, pathological Effects result.

[0003] 公开号201939391U公开了ー种负压皮肤活检环钻,其包括两端开ロ的圆筒形环钻体,环钻体前端为圆环形的环割刀,其特征在于,在环钻体内设有圆形橡胶塞,橡胶塞垂直于环钻体内壁,金属拉杆前端与橡胶塞铰连、金属拉杆后端伸出环钻体后端。 [0003] Publication No. 201939391U ー discloses a skin biopsy trephine negative species, including both ends of a cylindrical ring opening ro drill body, the front end of the trephine a circular annular ring cutting blade, wherein, in ring drill body provided with a circular rubber stopper, the rubber stopper is perpendicular to the inner wall of the trephine, and the rubber plug the front end of the metal rod hinged, the rear end of a metal rod extending the rear end of the trephine. 这种环钻在使用时,理论上靠环钻体内部的负压将病理标本吸附,但在实际操作过程中,由于皮肤较为柔软,环钻体内部产生的负压难以均匀的施加于皮肤上,最终导致局部上翻,从而破坏环钻体内部负压,造成皮肤病理取出失败,另外,受环钻结构限制,使用操作也非常不便。 Such trephine during use, in theory, by the negative pressure inside the body trephine adsorbed pathological specimens, but in actual operation, since the relatively soft skin, the negative pressure generated in the drill body inner ring is difficult to uniformly applied to the skin , resulting in turn locally, thus destroying the internal vacuum trephine body, resulting in skin pathology remove failed Further, the trephine limited by the structure, the operation is very inconvenient to use.

发明内容 SUMMARY

[0004] 本发明的目的在于提供一种设计科学,操作方便,具有环切、取出组织病理功能,降低皮肤病理取样难度的皮肤活检环钻。 [0004] The object of the present invention is to provide a scientific design, easy to operate, has a ring cut, remove pathological function, reduced skin biopsy sample Skin biopsy ring difficulty drill.

[0005] 为实现上述技术目的,本发明是采用以下技术方案实现的:ー种皮肤活检环钻,其包括: [0005] In order to achieve the above technical object, the present invention is achieved by the following technical solution: skins ー trephine biopsy, comprising:

[0006] 钻杆,其呈管状,内部设有活塞以及与活塞相连的推拉杆,推拉杆ー侧开有齿形缺ロ;钻杆下端设有用于连接钻头的外螺纹; [0006] The drill pipe, which is tubular, has an internal piston and a push rod connected to the piston, the push rod has a toothed side opening ー ro missing; the lower end of the drill rod provided with external threads for connecting the drill bit;

[0007] 手柄,垂直设置在钻杆上端的ー侧;手柄在钻杆一端设有沿长度方向的槽孔,槽孔内设有滑动销,滑动销在近推拉杆一端设有与齿形缺ロ配合的楔形头,另一端则设有复位弹簧;手柄上设有驱动滑动销移动的滑动键; [0007] handle vertically disposed on the upper end of the drill rod side ー; rod end is provided with a handle in the longitudinal direction of the slot, slots are equipped with slide pin, the slide pin is provided near one end of the push rod and the missing tooth ro mating wedge-shaped head, the other end is provided with a return spring; key drive slide pin provided with a sliding movement of the handle;

[0008] 钻头,包括钻头主体、环切刀、滑套;钻头主体上端设有用于连接钻杆的内螺纹;滑套位于钻头主体外侧,可在一定范围内沿钻头主体轴向往复移动,滑套下侧设有复位弹簧;滑套外设有可相对其周向运动的环切刀;钻头主体下端设有孔板,孔板上设有均匀分布的吸孔,孔板下端沿边缘设有ー圈胶垫。 [0008] The drill bit comprises a bit body, a cutter ring, sleeve; the upper end of the drill body is provided with an internal thread for connection of the drill pipe; sleeve positioned outside the drill body, the drill body can reciprocate in the axial direction within a certain range, the slip the sleeve side is provided with a return spring; sleeve can have a peripheral ring to the cutter circumferential movement relative thereto; the lower end of the drill body is provided with the orifice plate, is provided with suction holes uniformly distributed over the orifice plate is provided along the edge of lowerー circle pads.

[0009] 其工作原理为:进行病理取样时,将钻头孔板抵顶在皮肤上,用手向下驱动环切刀,由于滑套的存在,环切刀随滑套向下移动,当接触皮肤后,ー边旋转环切刀ー边继续让、环切刀向下移动,直到钻入合适的深度后,松开环切刀,其在复位弹簧的作用下进行复位,即离开皮肤;此时向上拉动推拉杆,当对皮肤产生足够的吸カ时,松开推拉杆,其通过楔形头进行定位,孔板上设有多个吸孔,可均匀的对皮肤产生吸力,并且孔板四周的胶垫相当于一个吸盘,进ー步保证了钻头与皮肤的结合力度,最后通过手柄,向上拉动钻杆即可将皮肤病理标本由体表取下。 [0009] The working principle is: when pathological samples, the drill plate abuts against the skin, the cutter ring driven down by hand, due to the presence of the sleeve, with the sleeve ring cutter is moved downward, when the contact after the skin, while rotating ring cutter ー ー while continuing to let the ring cutter is moved downward, until the proper depth drill, cutter release ring, which is reset in the reset action of the spring, i.e. away from the skin; this when the push rod is pulled up, when a sufficient suction to the skin ka, release push rod, which is positioned by the wedge-shaped head, the orifice plate is provided with a plurality of suction holes, can produce a uniform suction on the skin, and the plates four weeks the equivalent of a suction pad, to ensure that the drill bit further into ー binding strength of the skin, and finally through the handle, pulling up the drill pipe to be removed from the skin pathology specimen surface.

[0010] 本发明具有以下有益效果:由于钻头底部设有孔板,孔板上设有吸孔,外周设有胶垫,保证了钻杆产生负压后对皮肤的吸カ均匀,并可避免皮肤局部变形而破坏钻杆内部负压;钻头上的环切刀可相对于钻头主体轴向、周向运动,并设有复位装置,降低了环切步骤的操作难度;其结构设计合理,操作非常方便,大大提高了病理标本的取样效率,给医务エ作带来方便,给病人减小了痛苦,具有显著的实用性及新颖性。 [0010] The present invention has the following advantages: Since the drill bit is provided with a bottom plate, the orifice plate is provided with suction holes, with the outer periphery of the pad to ensure that the negative pressure is generated even after the drill pipe grades for skin absorption, and can avoid local deformation and damage skin negative pressure inside the drill pipe; cutter ring on the drill bit may be axially relative to the bit body, the circumferential movement, and a reset device, reduces the difficulty of the operation steps of the circumcision; rational design structure, operation very convenient, greatly improving the efficiency of sampling pathological specimens, medical convenient to bring as Ester, to reduce the suffering of patients, have significant utility and novelty.
