Embodiment 1

[0044] The present invention provides a technical solution: a biopsy needle set capable of directional bending for extracting brain tissue lesions, including a set of penetrating mechanism 10, and a biopsy taking mechanism, the penetrating mechanism includes such as Figure 1A The shown working casing 7 , the casing inner core 21 , and the first handle wheel 2 for grasping by both hands to adjust the penetration depth of the casing inner core and the rotation angle of the casing inner core.

[0045] Such as Figure 1B The top of the working sleeve 7 is fixedly equipped with a first handle 1, such as Figure 1A The inside of the working sleeve 7 is inserted with a sleeve inner core 21, such as Figure 1C The top of the sleeve inner core 21 is fixedly equipped with a first handle wheel 2, and the first handle wheel 2 is provided with two hand grasping holes 22 for fingers to pass through, and from the first handle wheel 2 The cylindrical hole 23 (such as Figure 1C and Figure...

Embodiment 2

[0058] A difference between this embodiment and embodiment 1 is that, as Figure 2B As shown, the second direction marking line 6 is correspondingly arranged on the upper and lower surfaces of the second handle wheel 4 and the sides of the fifth handle 5 and the third handle 3 respectively, when the second direction of the upper and lower surfaces of the second handle wheel 4 When the marking line 6 is aligned with the sides of the fifth handle 5 and the third handle 3 respectively, it can also ensure that the second cutting groove 43 is aligned with the second passing groove 32 .

[0059] Another difference between this embodiment and Embodiment 1 is that, as Figure 2C As shown, the second cutting groove 43 has three types of cutting knives disposed in the groove. Whereas each row of two plots represents the same type. The three figures in column S and column D respectively show the analysis of the force of the three types of cutting knives in the R direction when the seco...

Embodiment 3

[0062] This embodiment presents the structure of the first biopsy-taking mechanism assembly described in Embodiment 1, which is not shown in the figure because the structure is easy to understand in comparison with the first biopsy-taking mechanism assembly. The first biopsy mechanism assembly also includes a biopsy hose, a cutting hose and a biopsy needle core, all of which are composed of vertical cylinders, and each vertical cylinder has a first straight end, a second straight end and a third straight end respectively. Straight end, the second straight end is set as the tip of the cutting hose, the first cutting groove is opened on the tip of the cutting hose, the biopsy hose has a first straight end, and the first straight end is provided with a The first passing groove aligned with the first cutting groove, the biopsy needle core has a third straight end, the third straight end, the second straight end, and the first straight end are sequentially connected from the inside ...

Abstract

The invention relates to the technical field of biopsy needles, in particular to a biopsy needle suite capable of being bent in a directional mode and used for extracting brain tissue lesions, the biopsy needle suite comprises one or two sets of penetrating mechanisms and two sets of biopsy mechanism assemblies with straight ends and bendable ends, each penetrating mechanism comprises a working sleeve, a first handle, a sleeve inner core and a second handle, a first handle is fixedly installed at the top end of the working sleeve, and a sleeve inner core is inserted into the working sleeve. In the invention, the working sleeve and the sleeve inner core are combined and then inserted into a specified position and depth, the sleeve inner core is taken out, the biopsy taking mechanism is combined, then the working sleeve is inserted and extended out along the top end of the working sleeve, the working sleeve can be automatically bent to recover an initial angle, the working sleeve is aligned to a pathological tissue position needing to be sampled in the brain, and the biopsy needle core is pulled out; according to the device, bending adjustment of the collecting opening can be carried out according to the needle inserting position and the position condition of the diseased tissue, and the flexibility is higher.

Description

technical field [0001] The present invention relates to the technical field of biopsy needles, and is a serial application of Chinese patent ZL202122507186.8, specifically a biopsy needle set that can be oriented and bent for extracting brain tissue lesions. Background technique [0002] Biopsy of brain tissue lesions is an important means to diagnose the nature of brain lesions and determine the treatment plan. Since brain tissue is one of the organs with the most abundant blood supply in the human body, how to avoid damage to cerebral blood vessels and cause cerebral hemorrhage during biopsy surgery is the key to biopsy surgery. Among them, the puncture method of the biopsy needle and the method of sampling are important influencing factors. [0003] Existing brain tissue biopsy needles are generally straight and can only be used to extract tissue at the front end of the insertion direction. Therefore, there are very strict requirements on the angle, depth and position of ...
