Description
Technical Field
The utility model belongs to the technical field of the medical treatment, concretely relates to snatch formula department of stomatology and use tissue biopsy pen.
Background
The biopsy forceps used in the market at present are tools for biting, cutting and sampling the focus part of a human body, so as to clamp tissues of the lesion part, but in the clinical operation process, the biting and cutting type biopsy forceps are limited by narrow space in a forceps head component for flat solid tumors or tumors with good mobility due to small forceps heads, and the existing needle-containing biopsy forceps and needle-free biopsy forceps can only be used for sampling once or a small amount of samples, can not effectively cut enough samples at one time, and are easy to cause result false negative; therefore, how to improve current biopsy forceps, accomplish the sample to the focus fast, reduce the sample operation degree of difficulty, reduce the sample time, guarantee the sample size, become the technical problem that present medical technology field needs a solution urgently.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a formula of snatching for department of stomatology biopsy pen, use this biopsy pen can accomplish the sample to the focus in the short time, reduced the operation degree of difficulty of sample to greatly shorten the time of sample, can reduce patient's misery.
In order to solve the technical problem, the utility model adopts the following technical scheme: the tissue biopsy pen for the grabbing department of stomatology comprises a connecting rod and a pen body, wherein a tool bit is fixed at the front end of the pen body and is of a round table barrel-shaped structure with a small front part and a big back part, a sample recovery cavity, a spring installation cavity, a perforation and a sample recovery cavity are sequentially arranged in the pen body from front to back, spring-mounting chamber and perforation link up each other, the radius in spring-mounting chamber is greater than the radius that the chamber was retrieved to the sample, the spring-mounting chamber forms the step chamber with the sample recovery chamber, the connecting rod is worn to establish at the sample and is retrieved the chamber, in spring-mounting chamber and the perforation, the radius of connecting rod equals the fenestrate radius, the front end of connecting rod stretches into the sample and retrieves the intracavity, the front end of connecting rod is connected with the elasticity gripper, the rear end of connecting rod stretches out backward and is connected with the handle after the perforation, install the spring in the spring-mounting chamber of body of a writing brush, be fixed with the limiting plate on the connecting rod, the rear portion wall top press-fit of limiting plate and spring-.
The elastic steel wire claw is composed of four elastic steel wires, the shape of each elastic steel wire is arc-shaped, and the front end part of each elastic steel wire is of an L-shaped structure.
Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the utility model provides a grabbing sampling biopsy pen, which comprises a tool bit, an elastic steel wire claw, a pen body and the like; the cutter head is of a circular truncated cone-shaped structure and is used for cutting soft tissues; the elastic steel wire claw is formed by pre-bending four high-elasticity steel wires with the diameter of 0.5mm, when the handle is pressed, the elastic steel wire claw is opened in the forward extending process, after the elastic steel wire claw reaches the cut soft tissue, the handle is loosened, the specimen is grabbed by utilizing the elasticity of the spring and the deformation of the elastic steel wire claw, and the specimen is recovered and enters the specimen recovery cavity; by using the upper grabbing type sampling biopsy forceps, the focus can be sampled in a short time only by one-time pressing operation, so that the operation difficulty of sampling is reduced, the sampling time is greatly shortened, and the pain of a patient can be reduced; except the tool bit, the spring and the elastic steel wire claw part, the rest parts can be made of medical polypropylene plastics, so that the cost is low, and the purposes of one person for use and avoiding cross infection are achieved.
To sum up, the utility model discloses can accomplish the sample to the focus fast, reduce the sampling operation degree of difficulty, reduce the sample time, guarantee the sample size to it is painful to reduce patient, improves pathological diagnosis rate of accuracy.
