Abstract
A minimally invasive tumor biopsy sampling device comprises a sampling device rack, a cone cutting knife, a round bottom cutting knife, a rotary switch and a handle. The sampling device rack is a tubular member, and two pipe holes parallel to each other are arranged longitudinally inside the sampling device rack. The cone cutting knife is a tubular member, the front end of the cone cutting knife is a blade, and the cone cutting knife is placed in a pipe hole of the sampling device in a passing mode. The round bottom cutting knife is a rod-shaped member which is placed in another pipe hole of the sampling device rack in a rotating mode and passes through the another pipe hole, a bent blade part is arranged at the front end of the round bottom cutting knife, the blade part tightly clings to the front side of the blade of the cone cutting knife, the rotary switch is connected with the round bottom cutting knife, and the handle is arranged on the rear portion of the biopsy sampling device and is fixed at the rear end of the sampling device. The minimally invasive tumor biopsy sampling device can finish the work of tumor biopsy cut-in and cutting and taking samples at a time. The minimally invasive tumor biopsy sampling device has the advantages of being convenient to operate, complete in sampling, high in operation efficiency, and safe and reliable.
Description
Technical field:
This utility model relates to a kind of tissue sampler, and particularly a kind of minimally-invasive sampler for tumor autopsy belongs to technical field of medical instruments.
Background technology:
Early discovery, correctly diagnosis and in time treatment have important impact to the prognosis of tumor.Along with the improving constantly of detection methods and method, the accuracy rate of diagnosing tumor is improved gradually in recent years, tumor does not possess typical Imaging Features but still have greatly, and therefore simple image technology inspection exists the problem of difficult diagnosis.That accurately diagnosis needs is clinical, image and pathology three combinations, and wherein, pathological diagnosis plays pivotal role to the selection of therapeutic scheme.Aspiration biopsy is the main path that obtains the pathological diagnosis result.
Along with the development of oncomolecularbiology, the Comprehensive Treatment of individuation is more and more emphasized in the treatment of entity tumor in recent years.Chemotherapy can improve the complete resection rate of entity tumor, survival rate to patient behind the raising tumor resection plays an important role, and the pathology of tumor is the prerequisite of formulating the individuality chemotherapy regimen, but pathological diagnosis needs more specimen tissue, and therefore clinical a large amount of cases be unable to do without open surgical biopsy.Biopsy comprises puncture cutting and two kinds of forms of open biopsy, and the biopsy method effect that Present Domestic adopts outward clinically is all not ideal enough.Existing puncture Biopsy can only be at the fashionable biological tissue that cuts of thorn with sampler, and just needs will win the sample body time operative doctor with cutter the sample body to be cut down separately, seems very inconvenient.
Under related hospitals cooperated, the applicant had successfully carried out the research and development of " the lower minimally-invasive biopsy tumor of CT guiding " clinical technology, has improved sampler for tumor autopsy, so that open surgical biopsy and excision more accurately satisfy the requirement of pathological diagnosis.
The utility model content:
Technical problem to be solved in the utility model is the deficiency that overcomes existing sampler for tumor autopsy, a kind of minimally-invasive sampler for tumor autopsy is provided, it can be finished simultaneously incision and extract the sample body in the microtrauma puncture process work, thereby the purpose that reaches easy to operate, raises the efficiency.
The technical scheme that this utility model solves the problems of the technologies described above is as follows:
A kind of minimally-invasive sampler for tumor autopsy, it comprises the sampler frame, the cone cutter, end circle cutter, rotary switch and handle, described sampler frame is tube-like piece, its inside is vertically arranged with two mutual parallel pores, described cone cutter are the tube-like piece that front end has blade, it is placed through in the pore of this sampler frame, the circle cutter are for being placed through rotatably the rod-like element in another pore of sampler frame at the described end, its front end is provided with the blade of bending, this blade is close to the leading flank of described cone cutter blade, described rotary switch is connected with these end circle cutter, and described handle is positioned at the rear portion of this biopsy sampler and is fixed in the rear end of described sampler frame.
The blade of circle cutter of the described end is falcate, and has 90 ° bending angle.
Described rotary switch is positioned at the side of described handle.
Compare with existing sampler for tumor autopsy, the utlity model has following advantage:
1, justifies cooperating of cutter by cone cutter and the end, can once finish the incision of sample body and extract, thereby the utlity model has advantage easy to operate, that operating time is short, efficient is high.
2, live body that this utility model is got is complete, can guarantee to organize liveweight.
3, the utlity model has integrated structure, be convenient to sterilization and can disposablely use the minimizing cross-contamination.
Therefore, minimally-invasive sampler for tumor autopsy safety described in the utility model, effective, its using standard the minimally-invasive biopsy work of entity tumor, improved the accuracy rate of pathological diagnosis, reduced treatment cost, be of value to the treatment level that improves Chinese children malignant entity tumor, neuroblastoma and nephroblastoma, can realize larger Social benefit and economic benefit.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail, but can not limits with this protection domain of the present utility model.
See also Fig. 1 structural representation of the present utility model, diagram minimally-invasive sampler for tumor autopsy comprises sampler frame 3, cone cutter 5, the end circle cutter 4, rotary switch 2 and handle 1.Described sampler frame 3 is a tube-like piece, and in conjunction with consulting Fig. 3, its inside is vertically arranged with two mutual parallel pores.Described cone cutter 5 are tube-like piece, be used for organizing live body to do cylindrical cutting, please in conjunction with consulting Fig. 2, these cone cutter 5 are placed through in the pore of described sampler frame 3, and this pore is stretched out in the end, and its front end has the blade in order to the incision tissue.Circle cutter 4 of the described end are a rod-like element, are used for organizing the sample body to do the bottom cutting, and these end circle cutter 4 are placed through in sampler frame 3 another pores rotatably; The front end of circle cutter 4 of the described end is provided with the blade of bending, and this blade is falcate (seeing Fig. 2), and has 90 ° bending angle, and this blade is close to the leading flank (seeing Fig. 1) of described cone cutter 5 blades.Described handle 1 is positioned at the rear portion of this biopsy sampler, and it is fixed in the rear end of described sampler frame 3.Described rotary switch 2 is positioned at the side of described handle 1, and it is connected with circle cutter 4 of the described end, is used for handling the range of activity of these end circle cutter 4 rotations and control end circle cutter 4, is got to cut off and organizes the sample body.
Minimally-invasive sampler for tumor autopsy described in the utility model can disposablely be finished incision and extract the work of sample body, has advantage easy to operate, that sampling is complete, the efficient of performing the operation is high, safe and reliable.
