Description
本实用新型涉及一种宫颈细胞取样器刷头以及宫颈细胞取样器，属于医疗器械技术领域。The utility model relates to a cervical cell sampler brush head and a cervical cell sampler, belonging to the technical field of medical equipment.
临床上进行宫颈病变检查、HPV病毒检查等妇科检查时需要用到宫颈细胞采样刷，目前宫颈细胞采样大多是在医疗机构的临床科室进行，采用的医疗器械多数是简易的宫颈细胞采集器，其由刷头和细杆刷柄组成，刷头和刷杆可以同步转动、可拆卸。这种采样刷和采样方式的弊端在于，需要由扩阴器先对***扩张、将宫颈完全暴露在采样者视野中时才能进行采样，且宫颈细胞采样后不能更好的存取转移，操作只能在医疗机构由专业医务人员进行。这种采样方法需要两种医疗器械配合使用，限制了采样效率、浪费了医用耗材，且无法照顾有隐私采样需求的个人患者。鉴于此，申请人的在先中国专利申请CN114403942A提供了一种可视的自采宫颈细胞取样器，在宫颈刷内设置有观察机构，可以方便用户自主采用同时还大大提高了采样效率，且由于设计与其相匹配的取样瓶，使得样品可以稳固保存转移，减少与外界环境的接触，提高了细胞检测的精准度，而宫颈刷又可以重复消毒利用，大大节省了医用耗材。现有的这种宫颈细胞取样器，刷头本体部分包括径向向内间隔设置的三圈刷毛，且内圈至外圈的刷毛长度递减，从而使每圈刷毛接触宫颈口时张开角度不同，内圈刷毛能够进入宫颈口采集宫颈管内壁细胞，外圈刷毛则向外张开采集宫颈口外壁细胞。如果刷毛较硬，则接触宫颈口时不易弯曲，如果刷毛较软，则不易将组织细胞刮离。此外，由于该结构的刷头中主要是刷毛的端部用于接触宫颈口采集组织细胞，采集区域较小，使用效果不尽人意。In clinical practice, cervical cell sampling brushes are needed for gynecological examinations such as cervical lesion examinations and HPV virus examinations. Currently, cervical cell sampling is mostly performed in clinical departments of medical institutions, and most of the medical devices used are simple cervical cell collectors, which consist of a brush head and a thin brush handle. The brush head and brush handle can rotate synchronously and are detachable. The disadvantage of this sampling brush and sampling method is that the vagina must be dilated with a dilator to fully expose the cervix to the sampler's field of vision before sampling can be performed, and the cervical cells cannot be better stored and transferred after sampling, and the operation can only be performed by professional medical staff in medical institutions. This sampling method requires the use of two medical devices in combination, which limits the sampling efficiency, wastes medical consumables, and cannot take care of individual patients with privacy sampling needs. In view of this, the applicant's prior Chinese patent application CN114403942A provides a visual self-collecting cervical cell sampler, in which an observation mechanism is arranged inside the cervical brush, which can be convenient for users to use independently and greatly improve the sampling efficiency. Moreover, due to the design of the sampling bottle matched with it, the sample can be stably stored and transferred, reducing the contact with the external environment, improving the accuracy of cell detection, and the cervical brush can be repeatedly disinfected and reused, greatly saving medical consumables. In the existing cervical cell sampler, the brush head body part includes three circles of bristles arranged radially inwardly, and the length of the bristles from the inner circle to the outer circle decreases, so that each circle of bristles opens at a different angle when contacting the cervical ostium. The inner circle of bristles can enter the cervical ostium to collect the inner wall cells of the cervical canal, and the outer circle of bristles opens outward to collect the outer wall cells of the cervical ostium. If the bristles are hard, it is not easy to bend when contacting the cervical ostium, and if the bristles are soft, it is not easy to scrape away the tissue cells. In addition, since the ends of the bristles in the brush head of this structure are mainly used to contact the cervical opening to collect tissue cells, the collection area is small and the use effect is not satisfactory.

如图5、6所示，在本实施例中，所述杆体可分离地安装于所述手柄上。具体而言，所述杆体2与手柄1之间通过第二卡块11和第二卡槽22进行插拔连接，在所述手柄上1设置有第二卡块11，在所述杆体2的靠近手柄1的一端设置有第二卡槽22。由于在进行取样时杆体会局部***至体内，因此将杆体设置成为与手柄可分离的结构，杆体可以作为一次性耗材使用，保证器材的卫生。As shown in Fig. 5 and Fig. 6, in this embodiment, the rod body can be detachably mounted on the handle. Specifically, the rod body 2 and the handle 1 are plug-in connected via the second clamping block 11 and the second clamping slot 22. The handle 1 is provided with the second clamping block 11, and the end of the rod body 2 close to the handle 1 is provided with the second clamping slot 22. Since the rod body will be partially inserted into the body during sampling, the rod body is set to a structure that is detachable from the handle, and the rod body can be used as a disposable consumable to ensure the hygiene of the equipment.
所述支撑管31包括第一部分3a以及第二部分3b，所述第一部分3a以及第二部分3b之间的连接部呈锯齿状的拼接结构，所述第一部分3a位于靠近手柄一侧，第二部分3b设置有内螺纹并且螺接于所述杆体2端部的外螺纹23上。The support tube 31 includes a first part 3a and a second part 3b, the connection portion between the first part 3a and the second part 3b is a serrated splicing structure, the first part 3a is located close to the handle, and the second part 3b is provided with an internal thread and is screwed to the external thread 23 at the end of the rod body 2.
显然，上述实施例仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本实用新型创造的保护范围之中。Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
