Description

Tissue specimen collection device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a tissue specimen collection device.

Background Art

With the development of modern medicine, there are more and more methods for disease diagnosis, but the laboratory test results of specimens are still one of the most basic clinical diagnostic methods.

In clinical practice, tissue specimens are often collected during surgery to confirm the diagnosis or provide evidence of the lesion to the patient. However, most pathological specimens are small in size or mixed with blood and fluid in the abdominal cavity, making them difficult to detect. After the blood and fluid are sucked out of the operating table by an aspirator, the pathological specimens are easily sucked away and lost, which has a certain impact on the postoperative pathological diagnosis and subsequent treatment.

Utility Model Content

The utility model aims to provide a tissue specimen collection device, which is suitable for collecting tissue specimens in minimally invasive surgery or open surgery and providing pathological specimens for intraoperative and postoperative pathological diagnosis.

In order to achieve the above purpose, the utility model adopts the following technical solutions:

A tissue specimen collection device, in particular, comprises a collection component and a cavity component; a collection cavity is arranged in the collection component, and openings communicating with the outside are arranged at both ends of the collection cavity, and a specimen net bag for collecting specimens is connected to the opening at one end; a container cavity for storing waste liquid is arranged in the cavity component, and the container cavity is communicated with the collection cavity, and the specimen net bag is placed in the container cavity through the opening connected thereto, and a liquid discharge port communicating with the outside is arranged in the container cavity.

The working principle of the utility model is as follows:

Before the operation, the tissue specimen collection device is adhered to the bottom of the surgical collection bag. During the operation, the tissue specimen flows into the surgical collection bag along with the flushing fluid and then flows into the collection cavity. After the flushing fluid flows into the specimen net bag through the opening, the tissue specimen is left in the specimen net bag. Since the specimen net bag is placed in the container cavity, the flushing fluid filtered by the specimen net bag can enter the container cavity and be discharged to the external waste liquid collection bottle through the drain port. After the operation, the tissue specimen attached to the inner wall of the collection bag is flushed into the collection cavity, so that the tissue specimen is left in the specimen bag. Subsequently, the collection component and the cavity component are disassembled, the collection component is removed from the bottom of the surgical collection bag, and the specimen net bag is turned over, so that the tissue specimen can be placed in the specimen bag for labeling and inspection.

The discharge port can be adapted to different collection pipes, such as a reusable cannula, a disposable cannula or other functional cannula. The user can select a suitable cannula according to the application scenario of the tissue specimen collection device, so as to better collect tissue specimens.

In one embodiment, the collection member and the cavity member are designed separately. To ensure that the collection member and the cavity member are sealed, a sealing groove is provided on the cavity member, the opening of the sealing groove faces the access direction of the collection member, and a sealing ring is placed in the sealing groove; when the collection member and the cavity member are connected, the collection member squeezes the sealing ring, so that the collection member is sealed and connected to the cavity member, so as to ensure that the flushing liquid flowing into the tissue specimen collection device will not leak to the outside.

In one embodiment, a guide surface is provided in the collection chamber to guide the flushing liquid to flow toward the specimen net bag, and the guide surface is arranged between the two opposite openings of the collection chamber. Further, the cross-sectional profile of the collection chamber is truncated cone-shaped, and the specimen net bag is arranged on the upper bottom surface of the truncated cone, so that the flushing liquid flowing into the collection chamber can flow smoothly into the specimen net bag.

In one embodiment, either the collecting member or the cavity member is provided with an external thread, and the other is provided with an internal thread, so that the two are locked by threaded connection to achieve a sealed fit.

In one embodiment, a guide surface is provided in the container cavity to guide the flushing liquid to flow into the collecting tube. The guide surface tends to converge from the inner wall of the container cavity toward the location of the collecting tube, thereby guiding the flushing liquid stored in the container cavity to enter the collecting tube for discharge, thereby avoiding the flushing liquid from accumulating in the container cavity and causing contamination.

In one embodiment, the collection member and the cavity member can be designed as an integral unit with the buttocks bottom sheet. Specifically, the bottom of the buttocks bottom sheet encloses a collection cavity, and the specimen net bag is formed on the buttocks bottom sheet and is located below the collection cavity; an annular connecting ring is provided on the outside of the buttocks bottom sheet, and the connecting ring is integrally connected to the cavity member, and the specimen net bag is placed in the container cavity of the cavity member. By being used in conjunction with the buttocks bottom single unit, the tissue specimen collection device can reduce volume and weight, save installation steps, and make it more convenient.

Compared with the prior art, the tissue specimen collection device of the utility model has the following beneficial effects:

(1) The tissue specimen collection device is suitable for collecting tissue specimens during minimally invasive surgery or open surgery to avoid the loss of pathological specimens;

(2) The tissue specimen collection device is easy to use and simple to operate;

(3) The tissue specimen collection device is used in conjunction with a single buttocks bottom device, and does not require additional installation steps, making it convenient for medical staff to use.
