Visual puncture biopsy treatment needle

Abstract

The invention relates to the field of puncture diagnosis and treatment operation equipment, in particular to a visual puncture biopsy treatment needle. The treatment needle comprises a needle body 1, a digital control end 2 and a display 3, wherein the needle body 1 is made of metal, the outer surface of the middle is coated with an insulation layer, and the front end 11 and the back end 12 of the needle body are not coated with insulation layers. The treatment needle can be used for electrotome cutting or electric coagulation hemostasis while performing visual puncture diagnosis and treatment operation, integrates electrotome, endoscope, biopsy and treatment and is simple in structure, diversified in function and convenient to use.

Description

technical field [0001] The invention relates to the field of puncture diagnosis and treatment operation equipment, in particular to a visual puncture biopsy treatment needle. Background technique [0002] At present, minimally invasive technology strives to complete the diagnosis and treatment of lesions in the body with the smallest incision path and the least tissue damage. It has the characteristics of less bleeding, less postoperative pain, faster recovery, and minimal or no scars. Clinically, puncture and biopsy of subcutaneous tissue, kidney, liver, etc., or cone drainage, or puncture injection of drugs, or small needle-knife treatment (cervical spondylosis, lateral epicondylitis of humerus, stenosing tenosynovitis of flexor tendon, Three lumbar transverse process syndrome, chronic lumbar muscle strain, etc.), or foreign bodies (broken needles, broken catheters and other foreign bodies) are taken out, it may be necessary to rely on hand feeling, or predict the depth u...

Problems solved by technology

These methods are relatively blind, time-consuming, or require the assistance of other equipment, and mistakes occur from time to time

Sometimes, due to bleeding during the puncture, the diagnosis and treatment must be terminated, or even converted to open surgery for emergency treatment; or the tissue lesion cannot be observed, sufficient tissue samples cannot be obtained, and the diagnosis cannot be made

[0003] In addition, micro-plastic surgery technology has developed rapidly in recent years, and soft tissue filling such as collagen, hyaluronic acid, and granular fat has become the most cosmetic treatment. However, when injecting filling or extracting granular fat, the current blindness is not only easy to puncture blood vessels , cause bleeding, and it is easy to inject the above-mentioned filling materials through the vascular break, resulting in vascular embolism, blindness, hemiplegia and other serious consequences

[0004] In order to solve these problems, the visual puncture needle device (CN201668471U) uses a puncture needle with a camera and a liquid crystal display at the front end to realize visual puncture, but because there is no operation channel in the needle core, it cannot be performed under direct vision Operations such as obtaining tissue samples or hemostasis

A visible puncture needle and its visible puncture tube insertion needle (CN201160881Y) are provided with a tube insertion cavity, which can be used as a needle or injection after tube placement, but the tube cavity is too small to be inserted into an instrument for operation, and the cold light source used Both the image and the image are transmitted through optical fiber, and the image is connected and displayed in the rear end through the image receiving sensor and the image magnification display, but the image is a non-digital signal, which cannot be stored and transmitted

The visual puncture needle for thoracoabdominal surgery (CN203138637U) has 6-9 lumens in the needle body, which are used to insert the guide wire or laser beam to avoid entanglement, and can determine which lumen can be used to better diagnose and treat lesions. But its design must use a thicker needle body, which is not conducive to minimally invasive operation and lacks practicability

All above-mentioned inventions also have the shortcoming that can not stop bleeding at any time
