Abstract
The utility model discloses the device for preventing pneumothorax in a kind of biopsy, including hollow needle tubing, the cock body of Medical absorbable, push rod, the cock body of the Medical absorbable, one end of push rod are sequentially inserted into the inwall of hollow needle tubing, the cock body of the Medical absorbable, one end of push rod are slided in the inwall of hollow needle tubing, the other end of the push rod is free end, one end of the push rod is located at the top of the cock body of Medical absorbable, and the push rod is used to promote the cock body of Medical absorbable to leave hollow needle tubing.The utility model effectively can prevent the generation of pneumothorax during percutaneous lung puncture biopsy by application, and security is very high, and treatment cost is substantially reduced.
Description
Technical field
The utility model is related to the device for preventing pneumothorax in a kind of biopsy.
Background technology
For intrapulmonary peripheral type lesion, when can not be made a definite diagnosis with conventional inspection method, Drug eluting stent then has larger
Help, in addition for those late periods inoperable patients with lung cancer, selection radiation and chemotherapy before, for obtain histological type examine
Disconnected, Drug eluting stent also plays the role of larger.Percutaneous lung puncture biopsy by application is a kind of detection methods for having a wound, may be sent out
Angry chest, bleeding, embolism, needle track implantation and the danger of infection.Wherein pneumatosis in pleural cavity, referred to as pneumothorax.Pneumothorax is usually to trouble
Person brings great pain, or even threat to life.Clinical application method is after occurring pneumothorax, to be drawn using pleural cavity at present
The method of stream, suctions out external and mitigates pleural pressure, mitigate liquid intrathoracic gas, liquid using the principle of vacuum suction
With gas to the compressing of cardiopulmonary tissue and rehabilitation.This therapeutic modality belongs to remedial measures, but the treatment of increase patient into
Sheet and risk.It is that be more highly preferred to perspective is arranged if the generation of pneumothorax can be prevented during percutaneous lung puncture biopsy by application
Apply.
Utility model content
The purpose of this utility model is to overcome the shortcomings of that there is provided the biopsy that a kind of cost is low, safe in existing product
Prevent the device of pneumothorax in art.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
In a kind of biopsy of the present utility model prevent pneumothorax device, including hollow needle tubing, Medical absorbable cock body,
Push rod, the cock body of the Medical absorbable, one end of push rod are sequentially inserted into the inwall of hollow needle tubing, the Medical absorbable
Cock body, one end of push rod are slided in the inwall of hollow needle tubing, and the other end of the push rod is free end, one end of the push rod
Positioned at the top of the cock body of Medical absorbable, the push rod is used to promote the cock body of Medical absorbable to leave hollow needle tubing.
Preferably, the cock body of the Medical absorbable of the present utility model is in bar column.
Preferably, the surface of the cock body of the Medical absorbable of the present utility model has hydrogel layer.
Preferably, the material of the cock body of the Medical absorbable of the present utility model is polylactic acid PLA.
Preferably, the material of the cock body of the Medical absorbable of the present utility model be DL- lactide-co- ε-oneself in
Ester polymer.
Preferably, the material of the cock body of the Medical absorbable of the present utility model is 75/25PLGA polymer.
The beneficial effects of the utility model are as follows：The utility model can effectively be prevented during percutaneous lung puncture biopsy by application
The generation of pneumothorax, security is very high, and treatment cost is substantially reduced.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The technical solution of the utility model is described further with reference to Figure of description：
As shown in figure 1, in a kind of biopsy prevent pneumothorax device, it is characterised in that including hollow needle tubing 2, it is medical can
Cock body 3, the push rod 1 of absorption, the cock body 3 of the Medical absorbable, one end of push rod 1 are sequentially inserted into the inwall of hollow needle tubing 2,
The cock body 3 of the Medical absorbable, one end of push rod 1 are slided in the inwall of hollow needle tubing 2, and the other end of the push rod 1 is
Free end, one end of the push rod 1 is located at the top of the cock body 3 of Medical absorbable, and the push rod 1 is used to promote Medical absorbable
Cock body 3 leave hollow needle tubing 2.The cock body 3 of the Medical absorbable is in bar column.The table of the cock body 3 of the Medical absorbable
Has hydrogel layer in face.The material of the cock body 3 of the Medical absorbable is polylactic acid PLA or DL- lactide-co- 6-caprolactones
Polymer or 75/25PLGA polymer.
Protective case, the cock body for accommodating Medical absorbable is slided in its inwall；Push rod, the cock body for promoting Medical absorbable
Hollow needle tubing is left, biopsy needle track is closed into lung, prevents pneumothorax.
The cock body of Medical absorbable has the effect of good water swelling, and its twice straight can be expanded in five minutes
Footpath, and can absorb in vivo, it is very safe.Hollow needle tubing can effectively protect cock body, and protective case coordinates with push rod can be very
Cock body is easily promoted into inside of human body.
In use, one end insertion of hollow needle tubing is into the human body, the other end is exposed outside, by the cock body of Medical absorbable
Be inserted into hollow needle tubing, then prop up cock body with push rod, by cock body shift onto lung closing biopsy needle track, prevent pneumothorax.
The utility model effectively can prevent the generation of pneumothorax during percutaneous lung puncture biopsy by application, and security is very high, controls
Cost is treated to substantially reduce, it is simple in construction.
It should be noted that listed above is only a kind of specific embodiment of the present utility model.Obviously, the utility model
Above example is not limited to, there can also be many deformations.In a word, one of ordinary skill in the art can disclose from the utility model
Content all deformations for directly exporting or associate, be considered as protection domain of the present utility model.
