DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, Figure 1-Figure 3 As shown, a tumor cell collection device includes a needle tube housing 1, a grip assembly is provided at the upper end of the needle tube housing 1, a limiting groove 8 is defined in the needle tube housing 1, a needle tube 2 is provided in the needle tube housing 1, the needle tube 2 is slidably connected to the needle tube housing 1 in the limiting groove 8, a pressing piece 5 is provided at the upper end of the needle tube 2, a threaded sleeve 6 is provided at the position where the upper end of the needle tube 2 passes through the pressing piece 5, and a sampling assembly for collecting tumor cells is passed through the needle tube 2;

[0025] In this embodiment, the setting of the gripping component allows the doctor to avoid hand slipping during surgery as much as possible. The sampling component is inserted into the needle tube 2, which can prevent the lower end of the sampling component from contacting other tissues in the body during sampling, thereby affecting the sampling results.

[0026] In one embodiment, Figure 1 As shown, the holding assembly includes a handle 4, which is fixedly connected to the needle tube 2, and anti-slip grooves 14 are provided at both ends of the lower side of the handle 4; the setting of the anti-slip grooves 14 makes it convenient for the doctor to hold and operate the device with one hand, preventing the hand from slipping and causing unsuccessful sampling.

[0027] In one embodiment, Figure 2 As shown, a spring 9 is provided between the pressing piece 5 and the handle 4; the setting of the spring 9 can keep the needle tube 2 inside the needle tube housing 1 when it is not operated, without harming the patient. When it is necessary to sample the tumor, pressing the pressing piece 5 can make the needle tube 2 protrude from the lower end of the needle tube housing 1 and penetrate into the tumor to be sampled, and can automatically reset after the sampling is completed, thereby improving the efficiency of collecting tumor samples, reducing the operation time, and being more conducive to the patient's physical recovery.

[0028] In one embodiment, Figure 1 and Figure 3As shown, the sampling assembly includes a sampling rod 3, which is inserted into the interior of the needle tube 2. The upper end of the sampling rod 3 is provided with a thread 13, which is threadedly connected to the threaded sleeve 6. The lower end of the sampling rod 3 is provided with a sampling brush 7, and one side of the upper end of the sampling rod 3 is provided with a limit assembly. The threaded connection between the upper portion of the sampling rod 3 and the threaded sleeve 6 provided at the upper end of the needle tube 2 allows for more precise and meticulous operation. The provision of the sampling brush 7 eliminates the need for tumor excision, resulting in a smaller wound, which is more conducive to the closure and recovery of the sampling wound and improves the patient's postoperative recovery.

[0029] In one embodiment, Figure 3 As shown, the limiting assembly includes a plurality of limiting holes 10 and a limiting rod 11 cooperating with the limiting holes 10. The plurality of limiting holes 10 are opened on the sampling rod 3, and the limiting rod 11 can be inserted into the limiting holes 10. By inserting the limiting rod 11 into the limiting hole 10, the sampling rod 3 can be limited to a fixed position, so that the sampling rod 3 will not go to a deeper position, thereby preventing damage to other tissues in the patient's body.

[0030] In one embodiment, Figure 3 As shown, a scale is provided near the limiting hole 10 ; the scale is used to observe the depth of the sampling rod 3 penetrating into the tumor, and cooperates with the limiting component to make the operation safer.

[0031] In one embodiment, Figure 3 As shown, the upper end of the sampling rod 3 is provided with a knob 12, and the knob 12 is made of medical rubber and has a non-slip structure. The sampling rod 3 is thin and inconvenient to twist, and the setting of the knob 12 is more convenient for the doctor to operate. The non-slip structure of the rubber material can prevent the doctor's hands from slipping when there is tissue fluid on them.

[0032] In one embodiment, Figure 1 As shown, the lower end of the needle tube housing 1 is in an arc shape, and the needle tube housing 1 is made of medical stainless steel. The surface of the medical stainless steel material is smoother and only requires a smaller surgical incision for insertion. The arc-shaped lower end will not puncture the tumor over a large area, nor will it harm other tissues in the patient's body, which is more conducive to the patient's postoperative recovery.

[0033] The above embodiment discloses a tumor cell collection device. The doctor holds the device in his hand with a hand-held holding assembly. When the device does not need to be operated, the sampling brush 7 provided at the lower end of the sampling rod 3 is retracted into the needle tube 2, and the needle tube 2 is retracted into the needle tube housing 1. Before the operation, 11 is inserted into the corresponding limit rod 10. The doctor inserts the needle tube housing 1 through the wound opened during the operation. The arc surface of the lower end of the needle tube housing 1 is closely attached to the surface of the tumor to be sampled. The pressing piece 5 is pressed to make the lower end of the needle tube 2 puncture the tumor. By turning the knob 12 screws the sampling rod 3 downwards. When it reaches the required depth, due to the limitation of 11, the sampling rod 3 cannot go down any further, and the sampling brush 7 at the lower end of the sampling rod 3 samples the tumor; after the sampling is completed, the sampling rod 3 is screwed upwards and put into the needle tube 2. After releasing the pressed pressing piece 5, the needle tube 2 is retracted into the inside of the needle tube shell 1. Finally, the doctor pulls the needle tube shell 1 out of the patient's body, and the sampling is completed. The operation is convenient and quick, and will not harm other tissues in the patient's body. The wound for collecting the sample is small, which is beneficial to the patient's recovery after surgery.

[0034] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
