Description

Clinical gynecological tumor sampling device
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a clinical gynaecology's tumour sampling device that uses.
Background
The puncture biopsy is an important means method for tumor diagnosis, and can help doctors to know important pathological results such as tumor pathological typing, mutation and the like. Thereby helping doctors to better perform symptomatic treatment.
When in puncture biopsy, a needle cylinder with a needle head is needed to puncture a tumor, a piston is pulled, tumor cells are sucked into the needle cylinder by utilizing negative pressure generated in the needle cylinder, and then the needle head is pulled out, so that the purpose of sampling a tumor system is achieved.
However, during the process of pulling out the needle, the tumor cells remained on the outer wall of the syringe will contact with the normal tissue cells along with the process of pulling out the needle, and since the tumor cells have less glycoprotein and poor connectivity, the tumor cells are easy to move out of the wound left by puncture, which may cause the tumor to spread.
The Chinese patent No. 209285585U patent name: the utility model provides a clinical gynaecology tumour sampling device, discloses a sampling device, wherein inner tube and urceolus threaded connection, make the inner tube syringe needle get into the tumour and be rotatory the entering, have the inconvenience.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a clinical gynaecology's tumour sampling device that uses, the utility model discloses a puncture mode makes the syringe needle get into the tumour.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides a clinical gynecological tumor sampling device, includes the shell, the shell front end is provided with outer syringe needle, be provided with movable sampler barrel in the shell, the sampler barrel front end is provided with the sample needle, be provided with the piston in the sampler barrel, the piston connection push-and-pull rod, the handle is connected to the push-and-pull rod, be provided with a set of fixing device who is used for fixed sampler barrel on the shell, fixing device includes the fixture block, fixture block upper end fixed connection fixed block, the fixture block lower extreme passes the shell, the ring cover is fitted with a contraceptive ring to the fixture block has the spring, spring one end fixed connection fixed block, the fixed connection shell of the spring other end, be provided with on the sampler barrel one with fixture block matched with draw.
Further optimally, the bottom of the sampling cylinder is provided with a push cap.
The utility model has the advantages that: the outer needle head penetrates through normal tissues to reach a tumor part, the sampling tube is pushed by the push cap to enable the sampling needle to penetrate into the tumor, after the sampling needle enters the tumor, the corresponding fixing block is pressed down by a thumb to enable the clamping block to enter the clamping groove, a set of fixing devices are arranged, the corresponding fixing devices are selected to fix the sampling tube according to the depth of penetration, sampling is completed, the thumb is loosened, and the sampling tube is driven by the push cap.
Drawings
The present invention will be further explained with reference to the drawings and examples.
