Description

Technical Field

[0001] The invention relates to the technical field of gynecological tumor sampling, and more particularly to a gynecological tumor sampling device capable of avoiding secondary contamination of samples. Background Art

[0002] Gynecological tumor sampling equipment plays a vital role in gynecological medical practice. It has a wide range of applications. By obtaining tumor tissue samples for pathological examination, it can determine whether the tumor is benign or malignant, as well as the specific tumor type, such as cervical cancer, endometrial cancer, ovarian cancer, etc., providing key basis for the formulation of subsequent treatment plans.

[0003] Chinese patent application number CN202410945851.7 discloses a locatable gynecological tumor sampling device, including a display and an outer cylinder, the outer cylinder is provided with a sampling mechanism, the sampling mechanism includes a first electric push rod fixedly installed inside the outer cylinder, an inner cylinder penetrating to the outer surface of the outer cylinder is fixedly installed at the bottom of the first electric push rod, a second electric push rod is fixedly installed inside the inner cylinder, a connecting block is fixedly installed at the bottom of the second electric push rod, and a sampling needle is fixedly installed on the surface of the connecting block away from the second electric push rod.

[0004] In the above technical solution, the problem of insufficient length of the sampling needle, inability to adjust the extended length of the sampling needle as needed, and poor stability is solved. However, when the traditional tumor sampling device removes the tumor sample, due to the characteristics of the tumor tissue itself, it often has strong adhesion with the unresected tissue. When the sampling needle is withdrawn from the body, this adhesion will cause the resected sample to partially fall back into the body as the sampling needle moves, so that the amount of sample actually collected by the sampling needle is small, which cannot meet the basic sample quantity requirements of pathological detection. It may also be difficult to fully and accurately reflect the true situation of the tumor due to insufficient sample quantity, thereby affecting the accurate judgment of the patient's condition. In order to obtain a sufficient amount of sample, it is often necessary to perform the collection operation multiple times, which prolongs the time of the entire sampling process and affects the sampling efficiency of the tumor sampling device. Since the sampling needle is relatively slow to be withdrawn, more permeate from the surrounding tissue will enter the sample. The tissue permeate contains a variety of complex components. After mixing with the tumor sample, it will interfere with the subsequent biopsy of the sample. When pathological detection is performed later, too much permeate will affect the accuracy of the test results. Summary of the invention

After the positioning device 1 is lowered, the handle 23 is held, one end of the threading tube 6 is inserted into the perforation 2, and moved to the position where sampling is required. When the threading tube 6 reaches the sampling position, the clamping block 4 moves to the inside of the clamping slot 3 and is clamped, and then the negative pressure device 16 is lowered. When the equipment is working, negative pressure is generated inside the tube 6. At this time, the tissue to be sampled will enter the tube 6 through multiple sampling slots 7 under the action of pressure.

At this time, the spring 21 is compressed, and the sampling tube 8 rotates toward the sampling tube. The sample slot 7 moves in the direction of movement with the fixed plate 11, the arc cutter 12, the guide arc plate 13 and the storage box 14. The arc cutter 12 rotates to cut the sample tissue to be cut inside the sampling slot 7 at one time, and adopts a circular cutting method to avoid the sample sample from adhering to the uncut tissue and causing the sample to fall back. The cut sample tissue falls into the storage box 14 with the guide arc plate 13 for storage. After the sampling is completed, the sampling tube 8 is reset under the action of the spring 21.

The arc cutter 12 rotates to cut the sample tissue to be cut inside the sampling slot 7 at one time, and adopts a circular cutting method to avoid the sample sample from adhering to the uncut tissue and causing the sample to fall back. Compared with the traditional sampling equipment, the arc cutter 12 adopts a rotating motion to perform circular cutting on the sample tissue to be cut, so that the arc cutter 12 can sample the sample to be cut at one time, and prevent the sample sample from adhering to the uncut tissue and causing the sample to fall back, which meets the basic demand for sample volume for pathological detection, and not only improves the tumor sampling The speed and efficiency of the sampling tube 8 can fully and accurately reflect the real situation of the tumor and accurately judge the patient's condition. The cut sample tissue falls into the storage box 14 along with the guide arc plate 13 for storage. After the sampling is completed, the sampling tube 8 is reset under the action of the spring 21. At this time, the sampling tube 8 resets with the fixed plate 11, the arc cutter 12, the guide arc plate 13 and the storage box 14 to quickly reset. The firing sampling is adopted. After the sampling tube 8 is sampled, the storage box 14 is reset and misaligned with the sampling slot 7.

[0036] The steps of using the present invention are as follows: when the gynecological tumor sampling device for avoiding secondary contamination of samples is used, when sampling tumors, the medical staff holds the positioning device 1 for a long time, which will cause fatigue in the wrist of the medical staff. When the sampling tube 8 adopts the percussion sampling, the position of the sampling tube 8 and the penetration tube 6 will change due to the fatigue and shaking of the wrist, which will cause the sample to be inaccurate. Before the positioning device 1 is lowered, the double-sided patch is firstly pasted on the bottom surface of the multiple ring seats 42, and then the fixing seat 36 is fixed on the sampling position. On the skin, unfasten the fixing clip 41. At this time, the positioning device 1 passes through the swivel 39 and is adjusted according to the tumor position. At this time, the swivel 39 is squeezed by the positioning device 1 and rotates. When the positioning device 1 is lowered to the position, the rotating shaft 40 is fixed by the fixing clip 41. At this time, the swivel 39 is fixed, and the swivel 39 serves as a support for the positioning device 1 to prevent medical staff from getting tired at the wrist and shaking during sampling. The card block 4 is then connected with the card slot 3 to ensure the stability of the sampling device when sampling the tumor.
