Description

A device for extracting puncture specimens

technical field

The invention relates to the field of urology and is suitable for prostate biopsy.

Background technique

The incidence of prostate cancer is increasing year by year, and prostate biopsy has been widely carried out in various hospitals. Although the puncture is not complicated, it is often difficult to extract the specimen from the puncture gun into the collection bottle after the puncture because the specimen is thin and the glandular tissue is highly adhesive. Take it out and put it into a collection bottle, but the needle is round and relatively thin, which is inconvenient to operate, the specimen is easy to fall off, and there is a risk of instrument damage to the operator. Take the specimen directly by hand because the fingers are thicker and the specimen is thinner, which may break the specimen if it is not careful, and it is inconvenient to place it into a collection bottle with a small opening. At the same time, conventional specimens cannot clearly define the head and tail of the specimen, and the tissue site for pathological diagnosis cannot be clarified. At present, there is a lack of effective and convenient extraction and labeling methods for needle aspiration specimens in clinical practice.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art and solve the problem of difficult extraction and labeling of puncture specimens.

In order to achieve the purpose of the above invention, a puncture specimen extraction device is provided, which includes an upper slat and a lower slat connected by a hinge at the tail end; the head of the upper slat facing the lower slat is provided with an elastic specimen stopper, The lower slat is provided with a groove I for receiving a strip-shaped puncture specimen next to the abutting position of the specimen stopper.

The upper slat and the lower slat can realize the conversion between the face-to-face fitting and clamping state and the unfolding state under the combination of the hinge. The specimen stopper referred to herein is a solid body, and its elastic material can be bristles, silica gel, spring steel and other forms. Generally, the elongated specimen with certain toughness can be obtained through the puncture gun, and the specimen can fall into the groove I after the sample stop scrapes the specimen from the puncture gun in the groove I, so as to realize the connection between the specimen and the puncture gun. separate. The direction of the head and tail of the specimen can be directly marked on the upper and lower slats according to the direction of use.

One end of the length direction of the slats is hinged, and the groove I runs through the width direction of the slats.

Preferably, the groove I is located on the lower slat surface between the abutting position of the specimen block and the hinge; the lower slat is also provided with a hole for the specimen block to penetrate so that the upper slat and The card holes for the lower slats to fit snugly.

The lower slat surface referred to herein refers to the side of the lower slat facing the upper half. The tight fit of the upper and lower slats referred to herein means that the relatively flat and relatively large areas of the upper and lower slats can form a narrow gap that prevents the specimen from slipping in.

Preferably, the specimen stopper is shaped as a wedge for easy fixing in the clamping hole.

The wedge shape referred to here refers to a shape that is larger on the side toward the card hole and smaller on the side connected to the upper slat.

Preferably, the specimen block is made of medical silicone material.

Preferably, a concave silica gel pad is also laid in the groove I.

The concave surface of the silica gel pad faces outside the groove 1, thereby accommodating the specimen in the concave surface.

Preferably, the upper and lower slats are made of transparent medical resin.

Preferably, the upper slats and the lower slats are respectively provided with recesses on opposite sides close to the tail ends, which are convenient for fingers to press and locate.

The dimples adapt to the shape of human finger pads.

Preferably, anti-slip strips are protruded from the recesses.

Preferably, the upper slat is provided with a groove II at a position corresponding to the groove I.

The position corresponding to the groove I referred to here refers to the position where the groove I and the groove II can be aligned after clamping. Simultaneously, a silicone pad can also be arranged in the groove II here.

Through the cooperation of the elastic specimen stopper and the groove I under the clamping of the upper and lower slats, the specimen and the puncture gun can be separated conveniently, avoiding the pollution and difficulty of manual operation.

By setting the clamping hole and allowing the specimen stopper to snap in, the upper and lower slats can be fitted together, so that the stripped specimen can be kept in the groove I without sliding to other areas of the upper and lower slats, Facilitate the fixation of specimens.

The specimen block adopts a wedge shape, which can form a certain scooping and peeling effect through the beveled edge when peeling the specimen; it can also ensure the fixing strength when inserted into the card hole for fixing.

The use of medical silica gel can avoid the contamination of the specimen, and at the same time, it is easy to form and has suitable elasticity.

The concave silicone pad design avoids hard contact with the specimen during clamping and reduces the possibility of the specimen being crushed.

The medical resin material provides a certain hardness to ensure that the extraction device can be clamped, and its transparent property facilitates observation when clamping and scraping off the specimen. Labels are also conveniently attached to the slats.

The pit is set to prompt the finger to press the position, so as to prevent the specimen extraction device from slipping.

The anti-slip design allows the fingers to better apply pressure in the dimples.

The groove II is provided to further avoid hard contact with the specimen during clamping, reducing the possibility of the specimen being crushed.

The beneficial effect of the invention is that the specimen can be easily and quickly taken out from the puncture needle, and the specimen can be marked to clearly define the head and tail of the punctured tissue, thereby providing convenience for operation operation and pathological diagnosis.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

According to a kind of puncture sample extraction device shown in Fig. 1 to Fig. 3 and Fig. 6, it comprises an upper slat 1 and a lower slat 2 connected by a hinge 3 at the tail end; the head of the upper slat 1 faces the lower slat One side of the 2 is provided with an elastic specimen stopper 4, and the lower slat 2 is provided with a groove I5 for receiving a strip-shaped puncture specimen next to the abutting position of the specimen stopper 4. The groove I5 is located on the surface of the lower slat 2 between the abutment position of the specimen stop 4 and the hinge 3; the lower slat 2 is also provided with a hole for the specimen stop 4 to penetrate to allow the upper plate The clamping hole 6 where the strip 1 and the lower strip 2 fit closely.
