Description

Technical Field

[0001] This utility model relates to the field of biopsy needle technology, and in particular to a prostate biopsy needle. Background Technology

[0002] Prostate cancer is a serious prostate disease, and prostate biopsy is an important method for diagnosing it. Prostate biopsy mainly includes digitally guided prostate biopsy and ultrasound-guided transrectal or transperineal prostate system biopsy. When using digitally guided prostate biopsy, because the doctor cannot directly see the puncture site and needs to use their hand to guide the needle to find the puncture point, there is a risk of the needle tip accidentally injuring other tissues in the patient, and there is also a possibility that the needle tip may accidentally injure the doctor's finger when it comes into contact with the needle tip.

[0003] Chinese Patent CN209644959U discloses a prostate biopsy puncture needle, including a needle core, a syringe, and a sleeve fitted over the syringe. The top of the needle core is obliquely cut to form a first needle tip, and a sampling groove is formed on the needle core. The syringe can be fitted over the outside of the needle core. The end of the syringe near the first needle tip is obliquely cut to form a second needle tip. A push rod is connected to the end of the syringe away from the second needle tip. An insertion hole for communicating with the syringe is provided through the push rod. A through hole is formed at the end of the sleeve near the second needle tip. A notch is cut downward at the open end of the sleeve, and a slightly outwardly inclined clamping strip is provided at the notch. A gripping block is provided radially outward at the edge of the open end of the sleeve. An external thread is provided on the outer periphery of the sleeve near the clamping strip in the direction away from the opening. An adjusting ring is connected to the sleeve through the external thread. A return spring is provided between the bottom of the sleeve and the push rod. When no external force is applied, the syringe is completely retracted into the sleeve, which can effectively prevent the puncture needle tip from accidentally injuring other tissues of the patient and the doctor's fingers.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the above solutions are operated by a push rod to achieve the sampling effect. However, when the above devices are used, the live samples remain inside the sampling needle for a long time, which leads to sample dehydration and thus reduces the accuracy of biopsy.

Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] The purpose of this invention is to address the technical problems existing in the background art. This invention proposes a prostate biopsy needle. The combination of the sliding limiting component and the sliding limiting groove of this device can effectively improve the stability of the sliding plate and prevent problems such as tilting of the sampling needle. At the same time, the device can achieve the effect of storing elastic potential energy through the spring structure, thereby achieving the effect of quickly retracting the sampling needle and reducing the risk of sample exposure to the external environment.

[0007] This utility model proposes a prostate biopsy needle, including a shell and a cover plate installed and connected to its side.

[0010] By adopting the above technical solution, this solution can limit the sliding of the sliding component by combining the sliding component and the sliding rod, and the use of the waist-shaped hole structure can ensure the stable connection between the sliding component and the sliding plate.

[0011] Preferably, the sliding member is rotatably connected to a rotation lock member, and a limiting plate is connected to the outer side of the housing. The limiting plate has a limiting groove, which is L-shaped, and the inner wall of the limiting groove contacts the end of the rotation lock member away from the sliding member.

[0014] By adopting the above technical solution, this solution can retain water in the structure of the retracted sampling needle through water-containing cotton, thereby preventing the sample inside the sampling needle from dehydrating.

[0015] Preferably, a spring is connected to the inner wall of the housing, and a sliding plate is connected to the other end of the spring. A sliding limiting groove is provided on the inner side wall of the housing, and a sliding limiting component is connected to the outer arc surface of the sliding plate. The sliding limiting component is slidably connected to the inner wall of the sliding limiting groove.

[0016] By adopting the above technical solution, this solution can achieve the effect of automatic retraction and rebound of the sampling needle through the spring structure, thereby avoiding external environmental contamination of the sample.

[0017] Preferably, a mounting component is connected to the side of the sliding plate away from the spring, and the mounting component is connected to the sampling needle.

[0018] By adopting the above technical solution, this solution can facilitate the docking of the sampling needle with the sliding plate through the mounting component, thereby improving the installation efficiency of this device.

[0019] In summary, this utility model has at least one of the following beneficial effects:

[0020] This device effectively improves the stability of the sliding plate by combining the sliding limiting component and the sliding limiting groove, preventing problems such as the sampling needle tilting. At the same time, the device can achieve the effect of storing elastic potential energy through the spring structure, thereby enabling the device to quickly retract the sampling needle and reducing the risk of the sample being exposed to the external environment.

[0027] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0028] Example 1

[0029] like Figures 1-4 As shown, in order to solve the existing problems, this utility model discloses a prostate biopsy needle, including a housing 1 and a cover plate 2 installed and connected to its side. Anti-slip pads 3 are symmetrically connected to the outer side of the housing 1. An installation sleeve 4 is connected to the side of the cover plate 2 away from the housing 1. A needle sleeve 5 is connected to the installation sleeve 4. A triggering component 6 is connected to the outer side of the housing 1. A sampling component 7 is provided inside the needle sleeve 5.

[0030] The triggering component 6 includes a sliding bracket 601 connected to the outer side of the housing 1. A sliding rod 602 is connected to the side of the sliding bracket 601. A sliding member 603 is slidably connected to the sliding rod 602. A through waist-shaped hole is provided on the side of the housing 1. The sliding member 603 is slidably connected to both sides of the top of the waist-shaped hole.

[0031] The sliding member 603 is rotatably connected to a rotation lock member 605. A limiting plate 604 is connected to the outer side of the housing 1. The limiting plate 604 is provided with a limiting groove 606. The limiting groove 606 is L-shaped. The inner wall of the limiting groove 606 contacts the end of the rotation lock member 605 away from the sliding member 603.

[0032] The sampling component 7 includes a sampling needle 701 that is slidably connected to the inside of the needle sleeve 5. The outer arc side of the sampling needle 701 is provided with a sampling groove 702. The inner wall of the shell 1 is connected to a culture dish 703. The culture dish 703 is provided with a through hole at the center. A water-containing cotton 704 is connected inside the culture dish 703.

[0033] A spring 708 is connected to the inner wall of the housing 1, and a sliding plate 705 is connected to the other end of the spring 708. A sliding limiting groove 707 is provided on the inner side wall of the housing 1. A sliding limiting member 706 is connected to the outer arc side of the sliding plate 705. The sliding limiting member 706 is slidably connected to the inner wall of the sliding limiting groove 707. The top of the sliding plate 705 is connected to the sliding member 603.

[0034] The specific working principle is as follows: This device can effectively improve the collection efficiency of prostate live sampling. Compared with traditional devices, this device can achieve the effect of preserving the water content of live samples and reduce problems such as sample dehydration.

[0035] When this device is in use, the sampling needle 701 is installed inside the mounting member 709, and the needle sleeve 5 is installed inside the mounting sleeve 4. At this time, the sampling needle 701 is located inside the needle sleeve 5. Pulling the sliding member 603 causes the other end of the rotating locking member 605 to slide into the bending position of the limiting groove 606. At this time, the spring 708 is in a stretched state.

[0036] At this time, medical staff use the anti-slip pad 3 to clamp the device and insert it into the patient's body. The hollow needle sleeve 5 and the sampling needle 701 can store the live sample inside the sampling needle 701. After sampling, the medical staff moves the rotating locking part 605 to make the rotating locking part 605 leave the bending area inside the limiting groove 606, thereby releasing the spring 708. The spring 708 drives the sampling needle 701 to slide inward through the sliding plate 705, thereby achieving the contraction effect of the sampling needle 701. The petri dish 703 and the water-containing cotton 704 can prevent the sample from dehydrating.

[0037] Example 2

[0038] like Figures 1-4 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the first embodiment above, the prostate biopsy needle further includes: a mounting member 709 is connected to the side of the sliding plate 705 away from the spring 708, and the mounting member 709 is connected to the sampling needle 701.

[0039] The specific working principle is as follows: the sliding plate 705 enables the sampling needle 701 to retract and slide, thereby achieving the sampling effect of the device. At the same time, the sampling groove 702 provided on the sampling needle 701 enables the device to retain live samples and prevent the samples from falling off.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
