Puncturing stent and biopsy device

Abstract

The invention relates to the technical field of medical treatment articles, particularly relates to a puncturing stent and a biopsy device. The puncturing stent comprises a main body, a rod and a needle slot plate, wherein the main body can be connected with an ultrasonic probe and comprises a channel, and the channel is shorter than the rod; the rod can extend into the channel through a first endand can slide back and forth in a first direction, and the first direction is parallel with an extension direction of the rod; and the needle slot plate is fixed at a second end of the rod, and at least one puncturing hole parallel with the first direction is formed in the needle slot plate. According to the technical scheme provided by the invention, the structure of the puncturing stent is optimized, the volume of the puncturing stent is reduced, and the manufacturing cost is lowered; flexible telescopic operation can be realized between the rod and the main body, so that the position of the needle slot plate can be adjusted, the situation that the needle slot plate props against perineum of a patient is avoided, and a discomfort feel in the puncturing process is reduced; and furthermore, a puncturing needle can be separated from an ultrasonic probe during a surgery, thereby beneficial to flexible operation of a doctor.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a puncture bracket and a biopsy device. Background technique [0002] With the changes in people's lifestyles in recent years, the incidence of male prostate continues to rise, which seriously threatens the health and quality of life of the people, especially among elderly men. [0003] At present, prostate biopsy is generally used to detect prostate diseases. During ultrasonic biopsy, a small amount of sample tissue needs to be taken from different parts of the prostate to achieve the purpose of diagnosis. Biopsy has less trauma and high accuracy, so it is obtained wide clinical application. The commonly used biopsy sampling methods are the transrectal route and the transperineal route; among them, the transrectal route has some disadvantages, mainly including: 1. The ultrasound probe and the puncture stent reach the prostate through the rectal entrance, and the bacter...

Problems solved by technology

[0004] The transperineal puncture operation requires the use of a puncture bracket with an ultrasound probe. Currently, the transperineal puncture brackets used in hospitals mainly use puncture brackets similar to grid sieve plates, and can be used for puncture surgery only after being fixed with a custom-made stepper; there are the following Disadvantages: 1. Need to use a specific stepper, which is expensive and bulky, which affects the flexible operation of the doctor during the operation; 2. Cannot achieve the separation function of the needle holder during the operation; 3. The size of the sieve plate puncture holder Large placement in the perineum will seriously increase the patient's discomfort during the operation
