[0002] A soft tissue biopsy sampling device is a medical device specifically designed to obtain soft tissue samples. It can be inserted into the soft tissue suspected of being diseased and may contain a small piston or cutting mechanism to capture and preserve the tissue sample. Some advanced biopsy devices may have a sample chamber for storing the tissue sample.

[0003] Existing technologies, such as CN221229355U, a sampler for bone and soft tissue biopsy, fill the gap in the market for sampling devices that facilitate the extraction of soft tissue and bone. This device has the advantages of simple structure and easy operation.

[0004] However, this device still has some shortcomings in its use:

[0005] During the sampling process, the blade of this sampler may not be able to cut or grasp the target tissue smoothly, resulting in low sampling efficiency. The blade design may not be flexible enough.

[0006] The sampler is not suitable for sealing and storing the collected bone and soft tissue, which may lead to sample contamination or damage, thus affecting subsequent pathological analysis and diagnosis. Utility Model Content

[0007] The purpose of this invention is to provide a sampler for bone and soft tissue pathological biopsy, in order to solve the problems mentioned in the background art. In the sampling process, the blade of the sampler may not be able to cut or grasp the target tissue smoothly, resulting in low sampling efficiency. The blade design may not be flexible enough. The sampler is not convenient for sealing and storing the collected bone and soft tissue, which may lead to sample contamination or damage, thereby affecting subsequent pathological analysis and diagnosis.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0020] 2. In this utility model, the practicality and safety of the sampler are further improved by using a protective cylinder, guide hole, sealing plate, fixing bolts, observation mirror, and sterilization lamp in combination. The protective cylinder creates a relatively isolated environment for sampling operations, effectively blocking the intrusion of external contaminants and ensuring the cleanliness of the sampling process. The design of the guide hole facilitates the smooth entry and exit of the spiral sampling blade while ensuring the accuracy of the sampling path. The tight fit between the sealing plate and the fixing bolts ensures the tight sealing of the sample after sampling, preventing sample leakage and interference from the external environment. The introduction of the observation mirror allows the operator to directly observe the internal condition of the protective cylinder. The sterilization lamp can effectively sterilize the inside of the protective cylinder before and after sampling, further ensuring the sterility of the sample. Attached Figure Description

[0027] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0028] A sampler for bone and soft tissue pathological biopsy includes a protective cylinder 1, a sampling component 2 at the top of the protective cylinder 1, and a bottom component 3 at the bottom of the protective cylinder 1. The sampling component 2 includes a sealing cap 201 at the top of the protective cylinder 1, an adjustment knob 204 at the top of the sealing cap 201, a threaded rod 203 fixedly connected to the bottom of the adjustment knob 204, the threaded rod 203 passing through the sealing cap 201 and extending into the protective cylinder 1, the threaded rod 203 being threadedly connected to the sealing cap 201, a guide rod 209 fixedly connected to the bottom of the threaded rod 203, a spiral sampling blade 207 fixedly connected to the outer surface of the guide rod 209, both the guide rod 209 and the spiral sampling blade 207 being located inside the protective cylinder 1, a connecting groove 6 being opened at the top of the protective cylinder 1, and a sealing strip 202 fixedly connected to the bottom of the sealing cap 201, the sealing strip 202 extending into the connecting groove 6.

[0029] The guide rod 209 ensures the stability of the spiral sampling blade 207 during the sampling process, avoiding sampling deviations caused by improper operation. The design of the spiral sampling blade 207 not only improves the efficiency of cutting and grasping target tissues, but also ensures the integrity of the sample and reduces the possibility of sample damage.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the bottom component 3 includes a guide plate 301 fixedly connected to the bottom of the protective cylinder 1. A guide hole 302 is provided at the bottom of the guide plate 301. A sealing plate 303 is provided on the side of the guide plate 301, extending through the guide plate 301 and into the guide hole 302. The sealing plate 303 is slidably connected to the guide plate 301. An anti-slip hole 304 is provided at the top of the sealing plate 303. A fixing bolt 305 is provided at the bottom of the guide plate 301, extending through the guide plate 301 and into the sealing plate 303 for fixing. Bolt 305 is threadedly connected to guide plate 301. A fixing rod 208 is provided on the side of protective cylinder 1. The fixing rod 208 passes through protective cylinder 1 and extends into sealing strip 202. The fixing rod 208 is inserted into protective cylinder 1. A sterilization lamp 206 is fixedly connected to the bottom of sealing cover 201. The sterilization lamp 206 is an ultraviolet sterilization lamp.

[0032] The workflow of this utility model is as follows: When using the sampler designed for bone and soft tissue pathological biopsy, first check if the device is functioning properly. In a suitable working area, rotate the threaded rod 203 by turning the adjustment knob 204. The spiral sampling blade 207 punctures the bone and soft tissue pathological tissue, thereby driving the spiral sampling blade 207 to perform the sampling operation. The guide rod 209 ensures the stability of the spiral sampling blade 207 during the sampling process, avoiding sampling deviations caused by improper operation. The design of the spiral sampling blade 207 not only improves the efficiency of cutting and grasping the target tissue but also ensures the integrity of the sample. This reduces the possibility of sample damage. The protective cylinder 1 provides a relatively closed environment for sampling operations, effectively preventing the entry of external contaminants and ensuring the cleanliness of the sample. The guide hole 302 facilitates the entry and exit of the spiral sampling blade 207 and also ensures the accuracy of the sampling path. The cooperation between the sealing plate 303 and the fixing bolt 305 allows for a tight seal after sampling, avoiding sample leakage and interference from the external environment. The addition of the observation mirror 4 allows the operator to directly observe the inside of the protective cylinder 1. The setting of the sterilization lamp 206 can sterilize the inside of the protective cylinder 1 before and after sampling, further ensuring the sterility of the sample.
