Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of hemostasis external member and biopsy needle.
Background technology
Tumor is that body is under various carcinogenic factor effect, some cells of local organization lose the normal regulation to its growth on gene level, cause its clonal abnormality hypertrophy and the abnormality formed, sickness rate rises gradually in recent years, and age of onset declines gradually, early discovery, correct diagnosis, in time treatment have important impact to prognosis.Along with improving constantly of detection methods and method, the accuracy of diagnosis is improved gradually, but still have tumor greatly not possess typical Imaging Features, difficult diagnosis.Correct diagnosis needs clinical, image and pathology three to combine.Wherein, the selection of pathological diagnosis to therapeutic scheme plays pivotal role, and the diagnosis aspect that the Biopsy technology of tumor is applied in various entity tumor plays an important role the very extensive of application.
Also two problems is brought while more tumor patients obtain making a definite diagnosis, does is one how needle track stops blooding? in existing puncturing operation, hemostasis adopts hemostasis by compression, when hemostasis by compression has individual drawback to be outside compressing, blood has stopped, but in body, whether the blood of depths stops that to settle be the thorny problem of medical personnel.Does is two the transfers how reducing tumor cell? biopsy needle Direct perforantes is used in traditional biopsy, tumor tissues can taken out of along needle track, tumor is spread while the withdraw of the needle.
Utility model content
This utility model, for the problems referred to above, proposes a kind of hemostasis external member and biopsy needle.Solve the problem that the rear hemostasis of prior art puncture is comparatively difficult, and easily tumor tissues is taken out of along needle track while the withdraw of the needle, cause the problem that tumor spreads.
The technical scheme that this utility model is taked is as follows:
A kind of hemostasis external member, for the hemostasis after Biopsy, comprising:
Protective sleeve;
The sthptic sponge of Medical absorbable, be bar column, the inwall of sthptic sponge and described protective sleeve is slidably matched;
Push rod, for promote sthptic sponge leave protective sleeve enter human body relevant position hemostasis.
The sthptic sponge of Medical absorbable has good hemostasis assimilation effect, and can stop blooding within a few minutes, human body can basic absorption in vivo.Protective sleeve can available protecting sthptic sponge, and the shape of restriction sthptic sponge, protective sleeve coordinates with push rod can advance inside of human body by sthptic sponge very easily.
The external tube needles of a hollow is had during Biopsy, the organ other end that inside of human body is inserted in this external tube needles one end is positioned at human external, after completing every sampling biopsy or treatment, the work of hemostasis external member, first sthptic sponge is put into protective sleeve, external tube needles put into by protective sleeve, then by push rod, sthptic sponge is released, it is made to depart from external tube needles, finally protective sleeve and external tube needles are extracted out, sthptic sponge is stayed in human body, now sthptic sponge can absorb the blood of needle track wound, while absorbing blood, sthptic sponge self expands and reaches hemostasis, and sthptic sponge self expansion has also deadened the path that air enters, tumor cell also can not shift through needle track.
As preferably, described sthptic sponge comprises the body of column, and the two ends of body have the first hole distributed along its length, and body sidewall is distributed with the second hole.
Can ensure that sthptic sponge has larger compression stroke by arranging the first hole and the second hole, there is larger expansion space after entering human body.
As preferably, in described sthptic sponge, there is haemostatic medicament.
Haemostatic medicament and sthptic sponge combined effect, can stop blooding fast and effectively.And haemostatic medicament can be placed in the first hole or the second hole.
In order to make sthptic sponge absorb preferably, as preferably, the material of described sthptic sponge is absorbable oxidized cellulose hemostatic material.
As preferably, described protective sleeve comprises the body of cylinder, and one end of body has a horn mouth.
This horn mouth is the arrival end entering protective sleeve of hemostasis Cotton Gossypii, and bell-mouthed design can guide hemostasis Cotton Gossypii, and convenient hemostasis Cotton Gossypii enters in protective sleeve fast and effectively.
As preferably, one end of described push rod has limited block, and the external diameter of described limited block is greater than the internal diameter of body.
All can enter in body by effectively anti-throw-out lever by arranging limited block, danger and accident can be prevented.
The invention also discloses a kind of biopsy needle, a kind of biopsy needle, comprising:
The external tube needles of hollow;
Puncture needle, can embed in described external tube needles, enters in human body for driving external tube needles;
Sampling probe, can embed in described external tube needles, for obtaining the biopsy piercing through position;
Hemostasis external member, can embed in described external tube needles, for hemostasis;
Described hemostasis external member is any one above-mentioned hemostasis external member.
When biopsy needle uses, puncture needle penetrates in external tube needles, drives external tube needles to enter in human body, arrives borderline tumor, then puncture needle is extracted, penetrate sampling probe from external tube needles inside and obtain biopsy with this, after having sampled, extract sampling probe, hemostasis external member is finally used to stop blooding, during use, first sthptic sponge is put into protective sleeve, external tube needles put into by protective sleeve, then by push rod, sthptic sponge is released, it is made to depart from external tube needles, finally protective sleeve and external tube needles are extracted out, sthptic sponge is stayed in human body, the sthptic sponge stayed in human body can absorb the blood of needle track wound, while absorbing blood, sthptic sponge self expands and reaches hemostasis, and sthptic sponge self expansion has also deadened the path that air enters, tumor cell also can not shift through needle track.
As preferably, the external diameter of the bell-mouthed maximum cross section of described protective sleeve is greater than the internal diameter of described external tube needles.
The internal diameter that the external diameter of bell-mouthed maximum cross section is greater than external tube needles can effectively prevent protective sleeve from all entering in external tube needles, can prevent danger and accident.
The beneficial effects of the utility model are: protective sleeve, sthptic sponge and push rod three cooperatively interact, thus make sthptic sponge enter in human body, sthptic sponge can absorb the blood of needle track wound, while absorbing blood, sthptic sponge self expands and reaches hemostasis, and sthptic sponge self expansion has also deadened the path that air enters, tumor cell also can not shift through needle track; All can enter in body by effectively anti-throw-out lever by arranging limited block, danger and accident can be prevented; The internal diameter that the external diameter of bell-mouthed maximum cross section is greater than external tube needles can effectively prevent protective sleeve from all entering in external tube needles, can prevent danger and accident.
