Abstract
The utility model discloses an oral mucosa biopsy sampling device, include wherein one end confined sample barrel, the internal axis of rotation that is provided with of sampler barrel, swing joint had a plurality of spatula on the outer circumference of part of sample barrel blind end was close to to the axis of rotation, the sample is equipped with the spacing hole of a plurality of spatula with a plurality of spatula corresponding position on the barrel, and the spatula can be flexible in the spacing hole of spatula that corresponds. Stretching into and taking out the patient oral cavity when inside, it is spacing downthehole that the spatula is all ensconced to each spatula, has avoided the amazing patient oral cavity of spatula, leads to the patient to appear the emergence of the condition such as vomiting easily. Simultaneously, rapid sampling's biopsy sample volume is many, and active high, the biopsy result is more accurate, has alleviateed medical personnel's work load, has improved the degree of accuracy of the efficiency and the result of biopsy.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of oral mucosa sampling device for biopsy.
Background technology
In hospital clinical work, oral mucosa biopsy is the most effective method of diagnosing oral diseases, the oral cavity sampling device for biopsy of current use is primarily of the composition such as metal ball, wing, during use, allow patient contain lower metal ball, with wing scraping oral mucosa, this mode is serious to oral injury, and be easy to cause and swallow or vomit, bring very large misery to patient.At present, also occurred using air bag to replace the way of metal ball, or be wound around the way of cotton sliver at the outer surface of metal ball, alleviated the damage to patient oral cavity with this.But Manual operation handle, exists a lot of unstable factor, operation is slow, also easily causes unnecessary injury to patient.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, this utility model provides a kind of oral mucosa sampling device for biopsy, and structure is simple, easy to use, little to oral injury, sampling fast and easy.
For solving the technical problem of above-mentioned existence, the technical scheme that this utility model adopts is:
A kind of oral mucosa sampling device for biopsy, comprise the sampling cylindrical shell that wherein one end is closed, turning cylinder is provided with in described sampling cylindrical shell, described turning cylinder is connected with several spatulas on the part excircle of sampling cylindrical shell blind end, on described sampling cylindrical shell, the position corresponding with several spatulas is provided with several spatula spacing holes, and spatula can stretch in the spatula spacing hole of correspondence.
Below the further optimization of this utility model to such scheme:
Several spatulas described support knee respectively by spatula and are flexibly connected with turning cylinder, and several spatulas described support knee and arrange twist on the excircle of turning cylinder.
Further optimization: described sampling cylindrical shell is installed with micromachine away from one end of sampling cylindrical shell blind end, and described micromachine and turning cylinder are in transmission connection, has the motor switch for opening and closing micromachine in the outer setting of sampling cylindrical shell.
Further optimization: be rotationally connected by bearing between wherein one end of turning cylinder and sampling cylindrical shell, by supporting spindle nose and bearing rotational support is connected between the other end with sampling cylindrical shell blind end.
The inwall of described sampling cylindrical shell is provided with for carrying out spacing locating piece to turning cylinder with corresponding position on the excircle of turning cylinder.Prevent turning cylinder inordinate rotation.
During use, sampling cylindrical shell is goed deep into patient's cavity interior correct position, press motor switch, turning cylinder starts to rotate forward, spatula is stretched out from spatula spacing hole, then rotate sampling cylindrical shell to sample, after sampling, restart motor switch to rotate backward, spatula is return from spatula spacing hole, and then sampling cylindrical shell entirety is taken out in patient's cavity interior, like this, when stretching into and extract out patient's cavity interior, each spatula is all ensconced in spatula spacing hole, avoid spatula and stimulate patient oral cavity, patient is caused easily to occur the generation of the situations such as vomiting.Meanwhile, the biopsy sample amount of fast sampling is many, active high, and biopsy results is more accurate, alleviates the workload of medical personnel, improves the efficiency of biopsy and the accuracy of result.
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
