Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an efficient collection device for obtaining tissue specimens under arthroscopy. Background Art

[0002] Arthroscopic technology, as a minimally invasive surgical method, has been widely used in the diagnosis and treatment of joint diseases. With the continuous development of imaging technology and surgical instruments, arthroscopic surgery has become an important means of diagnosing intra-articular lesions. However, in the diagnosis of intra-articular infections, tumors and other lesions, obtaining sufficient and representative tissue specimens is crucial for pathological diagnosis and the formulation of treatment plans. Existing arthroscopic tissue specimen acquisition technology mainly relies on surgical instruments (such as basket forceps, grasping forceps, puncture needles, etc.) to cut or grasp suspicious tissues in the joint. In practice, these methods have limitations such as large randomness in sample acquisition, insufficient sample size, and low operating efficiency, and it is difficult to fully meet clinical needs.

[0003] In recent years, with the popularization of minimally invasive surgical techniques, the demand for efficient and accurate tissue sample acquisition devices under arthroscopy has continued to increase. Traditional surgical instruments are difficult to achieve multi-point and accurate tissue sampling in a complex joint cavity environment, and the sample acquisition process is prone to cause tissue damage, affecting the results of pathological analysis. Therefore, how to design a collection device that can efficiently and accurately obtain tissue specimens during arthroscopic surgery has become an urgent problem to be solved in this field. Summary of the invention

[0004] Purpose of the invention: The purpose of the present invention is to solve the deficiencies in the prior art through innovative structural design and technical improvements. The device can not only improve the efficiency and representativeness of sample acquisition, reduce randomness and errors in the operation process, but also effectively reduce the impact of sample damage and concentration dilution, thereby improving the accuracy of tissue pathology and microbiology testing, and providing a more reliable basis for clinical diagnosis and treatment.

[0005] Technical solution: An efficient collection device for obtaining tissue specimens under arthroscopy, comprising a shell, a water inlet is integrally formed at the lower left side of the shell, a water outlet is integrally formed at the upper right side of the shell, and a fixed base is arranged at the lower part of the shell; A filter screen is arranged above the interior of the shell, and a fixed rubber ring is fixedly connected to the outer wall of the filter screen. A groove is opened on the inner wall of the shell and located outside the filter screen, and the outer side of the fixed rubber ring extends to the inside of the groove.

[0006] Furthermore, a connecting plate is fixedly connected to the upper surface of the fixed base, a rotating rod is rotatably connected to the center of the upper surface of the connecting plate via a rotating shaft, and a water wheel is fixedly connected to the outer side wall of the rotating rod.

[0007] Furthermore, the outer side wall of the water inlet and the outer side wall of the water outlet are both fixedly connected with a threaded sleeve.

[0008] Furthermore, the entire shell is a cylindrical transparent structure made of high-strength, corrosion-resistant medical material.

[0009] Furthermore, a docking plate is fixedly connected to the upper surface of the fixed base and located on the outside of the shell, a sliding cavity is symmetrically formed inside the docking plate, arc-shaped sliding plates are slidably connected to the insides of the two sliding cavities, and the opposite sides of the two arc-shaped sliding plates are fixedly connected to arc-shaped card blocks, an arc-shaped card groove is integrally formed below the outer wall of the shell, the opposite sides of the two arc-shaped card blocks extend to the inside of the arc-shaped card groove, and a plurality of springs are fixedly connected between the opposite sides of the two arc-shaped sliding plates and the insides of the two sliding cavities.

[0010] Furthermore, a sealing rubber ring is fixedly connected to the upper surface of the fixed base and located on the outer side of the connecting plate.

[0011] Furthermore, the outer wall of the docking plate and the opposite sides of the two sliding cavities are provided with arc-shaped receiving grooves, and the centers of the opposite sides of the two arc-shaped sliding plates are fixedly connected with pull rods, and the opposite ends of the two pull rods extend to the interior of the two arc-shaped receiving grooves respectively and are fixedly connected with pull plates.

[0012] Furthermore, a scraper blade is fixedly connected to the top end of the rotating rod, and the scraper blade is in contact with the lower surface of the filter screen.

[0013] Furthermore, the opposite sides of the two pull plates are fixedly connected with control pull rings.

[0014] Beneficial effects: The present invention has a multi-point sampling function, which can accurately locate the suspicious lesion area in the joint cavity for tissue sampling, significantly reducing the randomness of sample acquisition. Through more comprehensive multi-point sampling, the representativeness and accuracy of the obtained samples are ensured, thereby improving the reliability of pathological and microbiological detection; The kinetic energy of the water drives the blades of the water wheel to rotate, forming turbulence, which prevents tissue samples from adhering to the filter net, maintains the sample suspension state in the lower area, and avoids pipe blockage. At the same time, the rotation of the water wheel controls the upper scraper blades to rotate simultaneously. The scraper blades can effectively keep the filter net clean and the water flow unobstructed, thereby improving sample collection efficiency and system stability. The present invention designs an efficient multi-point and multi-region sampling device, which makes sample acquisition faster and more convenient, and can obtain a sufficient amount of tissue samples in a short time. This design greatly reduces the operation time and complexity, improves the overall operation efficiency, and meets the clinical requirements for the quantity and quality of tissue samples. After the operation, the two pull plates can be pulled outward to remove the two arc-shaped card blocks from the interior of the arc-shaped card slot, so that the fixed base and the water wheel and scraper blades above it can be taken out together, which is convenient for maintenance of the device. It is also convenient to take out the tissue samples above the fixed base for inspection, which makes the device easy to assemble and operate, reduces the operating burden of medical staff, and can be reused, reducing the cost of use.

DETAILED DESCRIPTION

[0017] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0018] like Figure 1-Figure 3 As shown, an efficient collection device for obtaining tissue specimens under arthroscopy is provided, comprising a shell 1, a water inlet 2 is integrally formed at the lower left side of the shell 1, a water outlet 3 is integrally formed at the upper right side of the shell 1, a fixed base 4 is arranged at the lower part of the shell 1, a filter screen 5 is arranged at the upper part of the inner part of the shell 1, a fixed rubber ring 6 is fixedly connected to the outer side wall of the filter screen 5, and a groove 7 is arranged at the inner side wall of the shell 1 and located at the outer side of the filter screen 5; Before the start of arthroscopic surgery, the water inlet 2 provided in the device and the water outlet pipe of the arthroscopic planer are docked and fixed, and then the water outlet 3 is connected to the negative pressure suction device, and at the same time, it is ensured that all connection parts are firmly sealed to prevent leakage during the operation. Later, during the arthroscopic surgery, the doctor uses the planer to plane off the tissue debris, and then the tissue sample is first attracted to the lower area of ​​the shell 1 by the suction of the negative pressure suction device. Due to the effect of negative pressure, the water flow will quickly flow into the interior of the shell 1 to form an initial turbulent flow, which helps to push the tissue sample in the water flow to the central area of ​​the shell 1 and prevent the sample from directly adhering to the outside of the filter 5, that is, the tissue sample entering the shell 1 can be blocked by the filter 5 to prevent it from entering the water outlet 3. At the same time, the material of the filter 5 is medical stainless steel or corrosion-resistant polymer material, and the size of the mesh is precisely designed to balance the sample blocking ability and the smoothness of water flow. The shell 1 is divided into an upper water flow area and a lower tissue sample collection area by the filter 5, so as to facilitate the centralized collection of tissue samples.

[0019] like Figure 1 As shown, the top of the rotating rod 9 is fixedly connected with a scraper blade 22, the scraper blade 22 contacts the lower surface of the filter screen 5, the outer side of the fixed rubber ring 6 extends to the inside of the groove 7, the upper surface of the fixed base 4 is fixedly connected with a connecting plate 8, the center of the upper surface of the connecting plate 8 is rotatably connected with the rotating rod 9 through a rotating shaft, and the outer side wall of the rotating rod 9 is fixedly connected with a water wheel 10; When the water flows into the interior of the housing 1 through the negative pressure suction device and generates turbulence, the kinetic energy of the water flow causes the multiple blades of the water wheel 10 to rotate, thereby driving the entire water wheel 10 to rotate together. The rotation of the water wheel 10 can keep the tissue sample in the lower area in continuous motion, prevent the tissue sample from gathering or adhering to the filter 5, and avoid the blockage of the negative pressure suction system due to blockage. The water wheel 10 will drive the rotating rod 9 to rotate while rotating, thereby controlling the upper scraper blade 22 to rotate continuously through the rotation of the rotating rod 9. The continuous rotation of the scraper blade 22 can effectively remove the adhesion on the filter 5 and make it fall into the lower area, thereby preventing the filter 5 from being blocked and maintaining the smoothness of the water flow. Under the combined action of negative pressure suction and turbulence, the tissue sample remains suspended and moving in the lower area until it is deposited at the bottom of the housing 1. At the same time, due to the action of turbulence, the tissue sample will not accumulate on the filter 5, ensuring the effective collection and storage of more tissue samples, thereby increasing the practicality of the device.

[0020] like Figure 1 and Figure 2 As shown, the outer wall of the water inlet 2 and the outer wall of the water outlet 3 are both fixedly connected with a threaded sleeve 11; The threaded sleeve 11 can quickly and tightly connect the water inlet 2 and the water outlet 3 with the water outlet pipe of the arthroscopic planer and the negative pressure device, while ensuring the sealing performance so that the device can operate effectively.

[0021] like Figure 2 and Figure 4 As shown, a docking plate 12 is fixedly connected to the upper surface of the fixed base 4 and is located on the outer side of the shell 1, and a sliding cavity 13 is symmetrically formed inside the docking plate 12. The interior of the two sliding cavities 13 is slidably connected with an arc-shaped sliding plate 14, and the opposite sides of the two arc-shaped sliding plates 14 are fixedly connected with an arc-shaped card block 15, and an arc-shaped card groove 16 is integrally formed below the outer wall of the shell 1. The opposite sides of the two arc-shaped card blocks 15 extend to the inside of the arc-shaped card groove 16, and a plurality of springs 17 are fixedly connected between the opposite sides of the two arc-shaped sliding plates 14 and the inside of the two sliding cavities 13, respectively. An arc-shaped receiving groove 19 is opened on the outer wall of the docking plate 12 and is located on the opposite sides of the two sliding cavities 13. A pull rod 20 is fixedly connected at the center of the opposite sides of the two arc-shaped sliding plates 14, and the opposite ends of the two pull rods 20 extend to the inside of the two arc-shaped receiving grooves 19, respectively, and are fixedly connected with a pull plate 21. When the operation is over, the negative pressure suction device is turned off, and the water outlet pipe of the arthroscopic planer outside the water inlet 2 and the water outlet 3 is separated from the negative pressure device pipeline, so that the shell 1 can be separated from the system. Then, the two pull plates 21 can be pulled outward at the same time. The two pull plates 21 make the two arc-shaped sliding plates 14 slide back to back in the two sliding cavities 13 through the two pull rods 20 set, and the two arc-shaped blocks 15 can be pulled out of the arc-shaped slots 16 by the sliding of the two arc-shaped sliding plates 14. At this time, the fixed base 4 and the components above it can be disassembled together, and the doctor can remove the precipitated tissue above the fixed base 4 for subsequent pathological and microbiological analysis. After that, after the entire device is disinfected, the shell 1 can be inserted into the inner side of the docking plate 12, and then the two pull plates 21 and multiple springs 17 can be pulled at the same time to automatically fix the fixed base 4 and the shell 1, so that the device can be used repeatedly.

[0022] like Figure 1 As shown, a sealing rubber ring 18 is fixedly connected to the upper surface of the fixed base 4 and located on the outer side of the connecting plate 8; The sealing rubber ring 18 can ensure the sealing inside the housing 1, and ensure that the negative pressure suction device can normally suck the tissue samples into the lower area of ​​the housing 1 for centralized collection.

[0023] like Figure 4 As shown, the opposite sides of the two pull plates 21 are fixedly connected with control pull rings 23; The two control pull rings 23 can provide effective force points for doctors to quickly disassemble the fixed base 4, thereby improving the efficiency of sample collection.

[0024] like Figure 1 and Figure 2 As shown, the entire housing 1 is a cylindrical transparent structure made of high-strength, corrosion-resistant medical material; The entire shell 1 is made of high-strength, corrosion-resistant medical materials, which can ensure the stability of the overall structure of the collection device while also having effective corrosion resistance, maintaining good performance and appearance, and extending the service life of the entire collection device. It is suitable for long-term placement in medical environments such as operating rooms for backup and frequent use. At the same time, through its transparent design, the situation of internal collection of tissue specimens can be observed through the shell 1 during the operation, thereby improving the overall efficiency of obtaining tissue specimens under arthroscopy.
