Abstract
The utility model relates to a disposable gynaecological biopsy sampling forceps comprising upper forceps unit and a lower forceps unit. The upper forceps unit and the lower forceps unit are hinged with each other in an intersection manner to form a cutting part and a holding part. A tiger's mouth like a part of the hand between the thumb and the index finger is formed at a position of the cutting part of the upper forceps and the lower forceps unit. A container component which is hollow inside is arranged on a cutting surface of the upper forceps unit, and a cutting edge is arranged at the mouth of the container component. A cutting surface of the lower forceps unit corresponding to the container component can be used for sealing the mouth of the container component when the upper forceps unit and the lower forceps unit are closed. A sampling device which can rotate around a hinge joint to enter the container component to eject a sample when the upper forceps unit and the lower forceps unit are opened is arranged on the holding part of the lower forceps unit. Since the container component which is hollow inside is adopted to store the cut sample, the sample can be ejected from a cavity of the container component by the aid of a push rod when the upper forceps unit and the lower forceps unit are opened at the end of a sampling; and transferring of the sample is facilitated, operation accuracy is high, and stability is good.
Description
Technical field
This utility model relates to the medical surgical instrument technical field, especially a kind of disposable gynecological biopsy sample pickup tongs.
Background technology
Cervical biopsy is exactly Cervical biopsy, that is gets a fritter or a few block organization does the pathology inspection from cervix uteri, to determine diagnosis, multiplex have suspicious malignant at cervix uteri, or cervical scraping smear has suspicious cancerous cell, maybe can be suspected to have specific inflammation, as tuberculosis of cervix etc.Cervical biopsy is to make a definite diagnosis the most reliable foundation of cervical cancer.No matter be early stage or Advanced Cervical Carcinoma, all must check to determine histological type and the cell differentiation of cancerous protuberance by biopsy.
The cervical biopsy method is very simple, after sterilization pudendum, vagina, cervix uteri, with one special biopsy forceps, according to diseased region and requirement, get several little block organizations, be placed in 10% formalin solution and fix, send Pathology Deparment to do section, after dyeing, then the microscopically observation analysis makes pathological diagnosis.
Although the biopsy forceps that occurs in the market can be taken a sample, and in the time of in transferring samples to vessel, has not convenient property, because after downcutting sample, sample may stick on biopsy forceps, thereby can be more time-consuming when shifting; On the other hand, biopsy forceps mostly is stainless steel, therefore must carry out cleaning and disinfection when each the use, to prevent patient's cross infection.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provide a kind of disposable gynecological biopsy sample pickup tongs.
the technical scheme that its technical problem that solves this utility model adopts is: a kind of disposable gynecological biopsy sample pickup tongs, comprise pincers and lower pincers, described upper pincers and lower pincers cross-articulation form cut part and grip part, described upper pincers and lower pincers form a tiger’s jaw in shearing place, the shear surface of described upper pincers is provided with the container parts of hollow, the oral area of container parts has cutting edge, the lower pincers shear surface corresponding with container parts is upper, but the oral area of closed container parts when lower icarceration is closed, described lower pincers grip part is provided with is clamping up and down when breaking into two with one's hands and can rotate in order to enter the sampler that the container parts intracavity ejects sample around pin joint.
Described sampler is push rod, the push rod root is arranged at place, lower pincers grip parts, and described push rod is circular-arc take pin joint as the center of circle, and the push rod head is spherical, the arc radius of described push rod equates with the distance of container parts to pin joint, and the length of described push rod is identical with the degree of depth of container parts.Utilize the container parts of hollow to come the sample tissue of splendid attire well cutting in the design, good stability, guarantee to extract complete sample tissue, the convenient pathological tissue that downcuts of the cutting edge of container parts oral area, container parts adopts hollow design, can conveniently take out sample, can break into two with one's hands clamping up and down, when breaking into two with one's hands to 180 °, push rod enters the container parts of hollow, sample is ejected to vessel, so just facilitated the transfer of sample.
Further, for convenient cutting pathological tissue, prevent the sample tissue residue on the shear surface of lower pincers, the shear surface of described lower pincers is the plane.
As improving further, under described tiger’s jaw place, the pincers inner surface has the first projection, and upper pincers inner surface has the first socket with the first corresponding setting of projection;
Be positioned at grip part place upper pincers inner surface and have the second projection, lower pincers inner surface has the second socket with the second corresponding setting of projection, and described the second projection is circular-arc take pin joint as the center of circle.
Be positioned at and clamp up and down the joint place, grip part and be provided with the projection that is arranged on lower pincers, clamp the groove that is provided with the projection tabling on described, described projection, groove are all circular-arc take pin joint as the center of circle, and the arc radius of projection, groove is all identical with the arc radius of push rod.Projection can play the effect of guiding, the convenient closure of pincers up and down.
The grip part afterbody of described upper pincers and lower pincers is equipped with finger loop.Can better regulate the grasp dynamics like this, operate comfortable.
Described upper pincers and lower pincers grip parts are all to same direction bending, and bending angle is 130 °-140 °, utilizes this method can make whole biopsy forceps have more elastic force, and cutting effect is better.
As preferably, described bending angle is 135 °.
For intensity and the elasticity capacity of protecting bending part, be equipped with a reinforcement on edged surface in the bending part of described upper pincers and lower pincers, the trend of described reinforcement moves towards identical with tong arm.
The utlity model has following beneficial effect:
1, after the section, sample easily takes out: after container parts is equipped with the sample tissue, to clamp up and down and break into two with one's hands to 180 °, this moment, push rod just can eject the sample tissue in container parts to vessel, had solved the difficult problem that shifts of sample tissue, facilitated medical worker's operation, saved time;
2, the operation accuracy is high: owing to adopting container parts to come the lower sample tissue of splendid attire cutting, can guarantee to extract complete tissue samples, accuracy is improved, Simultaneous Stabilization, and sample is not easy to drop;
3, good springiness, better regulate the grasp dynamics: the afterbody tong arm bending that will clamp up and down, good springiness, more convenient medical worker operation is used more comfortablely, and cutting effect is better;
4, without cross infection: this utility model is disposable utensil, carries out the trouble of cleaning and disinfection when saving each the use, prevents patient's cross infection.
