Description
Technical Field
The utility model belongs to the technical field of the medical treatment, concretely relates to multistage location tissue biopsy device.
Background
Biopsy, which is a common pathological examination and diagnosis method, refers to a technique for taking out pathological tissues from a patient by cutting, clamping or puncturing to perform pathological examination as required for diagnosis and treatment; biopsy is the most important part in diagnosis pathology, and can make clear histopathological diagnosis for most of submitted pathology, and is used as the final diagnosis of clinic; during biopsy, accurate material taking is required, necrotic tissues or obvious secondary infection areas are avoided, multiple points of material taking are usually required during tissue biopsy, lesion tissues, tissues around lesions, normal tissues and the like are generally required to be taken, so that different tissues can be compared with each other, and the reliability of pathological diagnosis is improved; the material should be taken to a certain depth, and the material is required to be vertically cut in parallel with the depth of a focus; the biopsy forceps used at present can only take a pathological specimen of one point at a time, and need to be operated repeatedly due to the fact that multiple times of multipoint sampling are needed, so that the injury to a patient is large, and the biopsy time is prolonged.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide a multistage location tissue biopsy device, adopt this multistage location tissue biopsy device can be effectual while to focus multiple spot sample simultaneously, improve work efficiency greatly.
In order to solve the technical problem, the utility model adopts the following technical scheme: multistage location tissue biopsy device, including biopsy pole and sleeve, biopsy pole lower extreme is connected with the handle, biopsy pole one side has seted up a plurality of mounting grooves along vertical direction, it has the sample spoon to articulate in every mounting groove, the diapire has opened the spring groove along the horizontal direction in the mounting groove, the spring inslot is equipped with the spring, spring one end is connected with sample spoon middle part, the spring other end is connected with spring bottom of the groove portion, the outside at biopsy pole is established to slip cap from top to bottom at the sleeve, sleeve one side is opened along vertical direction has a plurality of square holes, a plurality of square holes set up position and sample spoon one-to-one, be equipped with T type groove in the sleeve wall of every square hole below, T type groove upside and square hole intercommunication, slidable mounting has the baffle in the T type.
Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the sampling spoon outwards pops out through the spring of connecting, through the sleeve upwards slides, and the bush wall makes the sampling spoon front end closed to the roof pressure of sampling spoon to surely get some pathology samples, and the push pedal that is equipped with in a plurality of square holes that set up on the bush wall and the bush wall of every square hole below, can be selective pass through the baffle with individual square hole and seal, thereby interval when can adjusting the multiple spot sample.
To sum up, adopt the utility model discloses can carry out the multiple spot sample simultaneously to the patient focus effectively, save operating time greatly.

Detailed Description
As shown in figures 1-5, the multi-stage positioning tissue biopsy device of the utility model comprises a biopsy rod 1 and a sleeve 2, the lower end of the biopsy rod 1 is connected with a handle 3, one side of the biopsy rod 1 is provided with a plurality of mounting grooves 4 along the vertical direction, each mounting groove 4 is internally articulated with a sampling spoon 5, the bottom wall of the mounting groove 4 is provided with a spring groove along the horizontal direction, a spring 7 is arranged in the spring groove 6, one end of the spring 7 is connected with the middle part of the sampling spoon 5, the other end of the spring 7 is connected with the bottom of the spring groove 6, the sleeve 2 is sleeved outside the biopsy rod 1 in a vertical sliding way, one side of the sleeve 2 is provided with a plurality of square holes 8 along the vertical direction, the setting positions of the square holes 8 are in one-to-one correspondence with the sampling spoon 5, a T-shaped groove is arranged in the wall of the sleeve 2, the periphery of the lower end part of the sleeve 2 is provided with a push plate 11.
The front end of the sampling spoon 5 is sharp and sharp, so that pathological samples can be conveniently cut off.
When using this utility model, the sampling point interval of operating personnel as required adjustment, upwards release baffle 9 through promoting slider 10, make solitary square hole 8 shield, then establish sleeve 2 from the 1 lower extreme cover of biopsy pole, guarantee when the cover is established that a plurality of sampling spoon 5 are not on same vertical straight line with a plurality of square hole 8, treat that sleeve 2 overlaps completely and establish back on biopsy pole 1, sleeve 2 is gone into to all equal roof pressures of sampling spoon 5, then insert patient's focus with biopsy pole 1, along the rotatory sleeve 2 of biopsy pole 1 axis, make sampling spoon 5 pop out from the square hole 8 of sleeve 2, then promote sleeve 2 forward, make the sampling spoon 5 who pops out impress in sleeve 2 again, sampling spoon 5 can surely get some pathology specimens at the in-process of impressing sleeve 2, it can at last take out biopsy pole 1.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
