Puncture biopsy guide device

Abstract

The invention discloses a puncture biopsy guide device. The puncture biopsy guide device comprises a guide device body (1) and a fixing device (4), a puncture biopsy needle installing hole (2) is formed in the guide device body (1), and the fixing device (4) is connected with the guide device (1). The puncture biopsy guide device has the advantages that a user can wear the guide device on the finger, guide the guide device to the point position needing puncture by means of touch sensation and penetrate a puncture biopsy needle through the guide device to perform puncture operation, the puncture biopsy needle can be prevented from scratching the user or a patient, and the guide device has the function of guiding the puncture biopsy needle, can prevent the needle point from damaging in-vivo tissue, which does not need puncture, of the patient when the puncture biopsy needle enters the body of the patient, is beneficial for determining the portion needing puncture and improving the accuracy of blind operation, and prevents the puncture biopsy needle from repeatedly getting in and out of the body of the patient when the same portion is punctured many times to effectively relieve the pain of the patient.

Description

technical field [0001] The invention relates to a guiding device for a puncture biopsy needle, in particular to a puncture biopsy guide. Background technique [0002] With the development of modern medicine, more and more biopsy operations are required clinically, and a considerable part of biopsy operations require clinicians to guide the puncture needle with fingers to perform biopsy, such as transrectal biopsy of the prostate. The needle biopsy operation guided by the doctor's finger has the following problems: [0003] 1. During the operation, the puncture needle may cut through the gloves, or even injure the medical workers. [0004] 2. The operator cannot safely and effectively judge the relative positional relationship between the puncture needle and the guiding finger, especially when performing a blind operation. [0005] 3. The directionality of the puncture needle is not good in the blind operation. [0006] 4. When the biopsy needle enters and leaves the cavit...

AI Technical Summary

Problems solved by technology

[0003] 1. The puncture needle may cut through the gloves during the operation, and may even injure medical workers.

[0004] 2. The operator cannot safely and effectively judge the relative positional relationship between the puncture needle and the guiding finger, especially when performing a blind operation

[0005] 3. The puncture needle directivity is not good in blind operation

[0006] 4. When the biopsy needle enters and exits the patient's cavity, the exposed needle tip can easily injure the patient's normal tissues, such as the rectum and anal canal mucosa

[0007] 5. For some tissues that require multi-point puncture, such as the prostate, the puncture needle needs to enter and exit the patient's anal canal repeatedly, which not only aggravates the patient's discomfort during the operation, but also greatly increases the probability of trauma to the rectum and anus
