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.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1;

in the figure, 1, a shell, 2, an outer needle head, 3, a sampling cylinder, 4, a sampling needle, 5, a piston, 6, a push-pull rod, 7, a push cap, 8, a handle, 9, a clamping groove, 10, a clamping block, 11, a spring and 12 are fixed blocks.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1 and 2, a clinical gynecological tumor sampling device comprises a housing 1, an outer needle 2 is arranged at the front end of the housing 1, a movable sampling cylinder 3 is arranged in the shell 1, a sampling needle 4 is arranged at the front end of the sampling cylinder 3, a piston 5 is arranged in the sampling cylinder 3, the piston 5 is connected with a push-pull rod 6, the push-pull rod 6 is connected with a handle 8, a group of fixing devices for fixing the sampling tube 3 are arranged on the shell 1, the fixing devices comprise fixture blocks 10, the upper end of the fixture block 10 is fixedly connected with a fixing block 12, the lower end of the fixture block 10 penetrates through the shell 1, a spring 11 is sleeved on the fixture block 10, one end of the spring 11 is fixedly connected with a fixture block 12, the other end of the spring 11 is fixedly connected with the shell 1, and the sampling cylinder 3 is provided with a clamping groove 9 matched with the clamping block 10. And a push cap 7 is arranged at the bottom of the sampling tube 3.

The utility model discloses a theory of operation: 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.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
