Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a biopsy instrument for pathology. Background Technology

[0002] Pathological biopsy, or biopsy of a living tissue, is a crucial diagnostic tool in modern medicine. When doctors discover abnormalities in a patient's lesions or require further clarification of the lesion's nature, they opt for a biopsy. This involves surgical methods such as local excision, forceps biopsy, puncture, scraping, or removal of the diseased organ to obtain diseased tissue or organs from the patient for histological examination and diagnosis. For example, when a suspicious lesion is found during colonoscopy, biopsy forceps are used to extract the lesion tissue, which is then sent to the pathology department for examination to determine the nature of the lesion. Pathological biopsy can determine the specific type of lesion; for instance, a gastrointestinal biopsy can identify chronic atrophic gastritis or peptic ulcers. Furthermore, it can differentiate between benign and malignant tumors, providing essential information for clinical treatment.

[0003] With the continuous advancement of medical technology, pathological biopsy is also constantly developing. However, traditional pathological biopsy usually involves removing the biopsy tissue from the patient's body and then transferring it in a container. This process is not only cumbersome, but also prone to cross-contamination during the removal and transfer of the biopsy tissue, affecting the structure of the biopsy tissue for analysis. Therefore, this application provides a biopsy instrument for pathology to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a biopsy instrument for pathology departments, so as to solve the problems of cumbersome operation and easy cross-contamination in existing pathological biopsy methods.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pathology biopsy instrument includes a control tube with a front end and an insertion tube at the front end. The insertion tube is connected to a sampling tube, and a sampling knife is provided at the end of the sampling tube away from the insertion tube. The control tube has a pump chamber inside, and an air extraction assembly is provided inside the pump chamber. The insertion tube connects the sampling tube and the internal space of the pump chamber.

[0007] Optionally, the pumping assembly includes a piston assembled in the pump chamber, with a control lever connected to the end of the piston away from the insertion tube, the control lever passing through the end face of the control tube away from the sampling tube.

[0008] Optionally, a first retaining ring is provided on the outer wall of the end of the control tube away from the sampling tube, and two first retaining rings are symmetrically arranged. A second retaining ring is connected to the end of the control lever that extends out of the control tube.

[0009] Optionally, a ring seat is provided at the end of the sampling tube facing the control tube, and the insertion tube is inserted into the ring seat.

[0010] Optionally, a sterile, breathable membrane is provided inside the sampling tube near the seat.

[0011] Optionally, a membrane flap is provided on the end wall of the sampling tube facing the ring seat, and multiple membrane flaps are arranged around the ring seat, with the multiple membrane flaps gradually converging towards the end away from the ring seat.

[0012] Optionally, a positioning post is provided on the end face of the sampling tube facing the control tube, and a positioning hole is provided on the end face of the control tube to be inserted into and adapted to the positioning post.

[0013] Optionally, the end of the operating tube facing the sampling tube is provided with an adapter hole, the insertion tube extends out of the adapter hole and is inserted into the ring seat, the ring seat is inserted into the adapter hole, and a second medical rubber ring is provided on the inner wall of the adapter hole.

[0014] Optionally, a first medical rubber ring is embedded inside the ring seat.

[0015] Optionally, the sampling knife has a conical blade at the end away from the sampling tube, and sharp edges on both sides of the sampling knife.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, the sampling tube and the control tube are used. The ring at the end of the sampling tube is fitted onto the insertion tube and inserted into the matching hole on the end face of the control tube. The insertion tube connects the pump chamber and the inside of the sampling tube. The control tube is held and inserted into the lesion. Using a sampling knife with a conical blade and a sharp edge, the lesion tissue in the patient's lesion can be punctured. Pulling the control lever moves the piston away from the sampling tube to generate suction. The suction force generated in the sampling tube can draw the punctured lesion tissue into the sampling tube. The sampling tube can be transferred for examination simply by pulling it out of the control tube. Compared with the traditional method of removing the live tissue from the patient's body and then transferring it, the operation is more convenient and reduces the risk of sample contamination. The sterile breathable membrane in the sampling tube can prevent the live tissue inhaled into the sampling tube from coming into contact with the insertion tube. As a result, the control tube can be reused. Each time a sample is taken, only the sampling tube needs to be attached to the front end of the control tube, which reduces the cost of use.

[0033] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides a pathology biopsy instrument, including a control tube 1. The control tube 1 has a front end, and an insertion tube 6 is provided at the front end of the control tube 1. The insertion tube 6 is inserted into a sampling tube 2. A sampling blade 3 is provided at the end of the sampling tube 2 away from the insertion tube 6. The sampling blade 3 is located on the end face of the tube wall of the sampling tube 2. The control tube 1 has a pump chamber 7 inside, and an air suction component is provided inside the pump chamber 7. The insertion tube 6 connects the sampling tube 2 and the internal space of the pump chamber 7. Through this structure, the insertion tube 6 connects the pump chamber 7 and the internal space of the sampling tube 2. The control tube 1 can be held by hand. The sampling tube 2 is inserted into the lesion, and the lesion tissue inside the lesion is punctured using the sampling knife 3. Then, air is drawn out using the suction component, generating suction in the sampling tube 2, and the puncturable lesion tissue is drawn into the sampling tube 2. The sampling tube 2 can be transferred for examination simply by pulling it out of the control tube 1. Compared with the traditional method of removing the live tissue from the patient's body and then transferring it, the operation is more convenient and reduces the risk of sample contamination. In addition, the control tube 1 can be reused, and the sampling tube 2 only needs to be attached to the front end of the control tube 1 each time sampling is performed, which reduces the cost of use.

[0034] like Figures 1 to 4 As shown, the suction assembly includes a piston 8 assembled in the pump chamber 7. The end of the piston 8 away from the insertion tube 6 is connected to a control lever 9. The control lever 9 passes through the end face of the control tube 1 away from the sampling tube 2. A first retaining ring 4 is provided on the outer wall of the end of the control tube 1 away from the sampling tube 2. Two first retaining rings 4 are symmetrically arranged. The end of the control lever 9 extending out of the control tube 1 is connected to a second retaining ring 5. Two fingers can pass through the first retaining ring 4 to hold and control the control tube 1. The thumb can pass through the second retaining ring 5 to pull the control lever 9 to drive the piston 8 to perform suction.

[0035] like Figures 1 to 6 As shown, the sampling tube 2 has a seat 10 at one end facing the control tube 1. The insertion tube 6 is inserted into the seat 10. A sterile breathable membrane 12 is provided inside the sampling tube 2 near the seat 10. The sterile breathable membrane 12 can prevent the live tissue inhaled into the sampling tube 2 from contacting the insertion tube 6. A membrane flap 11 is provided on the end wall of the sampling tube 2 facing the seat 10. Multiple membrane flaps 11 are arranged around the seat 10. The multiple membrane flaps 11 gradually converge towards the end away from the seat 10. After the insertion tube 6 is inserted into the seat 10, it can expand the multiple membrane flaps 11. After the sampling tube 2 is pulled out of the control tube 1, the multiple membrane flaps 11 converge to block the seat 10, which is conducive to the transfer of the sampling tube 2 containing live tissue.

[0036] like Figures 1 to 6As shown, a positioning post 14 is provided on the end face of the sampling tube 2 facing the control tube 1. A positioning hole 17 is provided on the end face of the control tube 1 to fit the positioning post 14 for rotational limitation of the control tube 1 and the sampling tube 2. An adapter hole 15 is provided on the end of the control tube 1 facing the sampling tube 2. The insertion tube 6 extends out of the adapter hole 15 and is inserted into the ring seat 10. The ring seat 10 is inserted into the adapter hole 15. A second medical rubber ring 16 is provided on the inner wall of the adapter hole 15. A first medical rubber ring 13 is embedded inside the ring seat 10, which is conducive to the stable insertion of the control tube 1 and the sampling tube 2. A conical blade is provided on the end of the sampling knife 3 away from the sampling tube 2. Sharp blades are provided on both sides of the sampling knife 3, which is conducive to the sampling knife 3 piercing the patient's diseased tissue.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] In use, the ring seat 10 at the end of the sampling tube 2 is fitted onto the insertion tube 6 and inserted into the adapter hole 15 on the end face of the control tube 1. The positioning pin 14 at the end of the sampling tube 2 is inserted into the positioning hole 17 on the end face of the control tube 1, so that the control tube 1 and the sampling tube 2 are connected and can rotate synchronously. After the insertion tube 6 is inserted into the ring seat 10, it can expand multiple membrane flaps 11. At this time, the insertion tube 6 connects the pump chamber 7 and the inside of the sampling tube 2. Holding the control tube 1, it is inserted into the lesion. Using the sampling knife 3 with a conical blade and a sharp edge, the lesion tissue in the patient's lesion can be punctured. Then, the control lever 9 is pulled to move the piston 8 away from the sampling tube 2 and into the lesion. Inhalation generates suction within the sampling tube 2, drawing the punctured lesion tissue into it. The sampling tube 2 can then be easily removed from the control tube 1 to transfer the living tissue within. Compared to the traditional method of removing the living tissue from the patient and then transferring it, this method is more convenient and reduces the risk of sample contamination. The sterile, breathable membrane 12 within the sampling tube 2 prevents the living tissue from contacting the insertion tube 6, allowing the control tube 1 to be reused. Each time a sample is taken, only the sampling tube 2 needs to be attached to the front end of the control tube 1, reducing usage costs.

[0039] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
