Abstract
This utility model belongs to pleura movable detecting apparatus, refers in particular to a kind of C shape Pleura biopsy needle.Comprise nook closing member, trocar sheath that turning set is loaded on nook closing member outer surface, the inner chamber of trocar sheath and the snakelike neck of wire type biopsy forceps rotate adaptation; Described trocar sheath is c-shaped, described nook closing member comprise connect successively from front to back be positioned at anterior needle point, shank and backshank, described shank adopts and the rigid with deflection degree adaptive with trocar sheath to make.The problem that running resistance is large, operation degree is higher that this utility model solves little, the nook closing member of parietal pleura biopsy scope that prior art exists and biopsy forceps has the parietal pleura biopsy scope that expands, nook closing member in advantages such as the compliance of C shape overcoat in-pipe are good.
Description
Technical field
This utility model belongs to pleura movable detecting apparatus, refers in particular to a kind of C shape Pleura biopsy needle.
Background technology
Pleura biopsy is the important means making a definite diagnosis the pleural diseases cause of disease.At present, the method that pleura obtains has: 1, thoracotomy, electronics thoracoscope, branchofiberoscope substitute Video-assisted mini-thoracectomy: these method and technologies are complicated, expensive equipment, and operation wound is large, and complication is many, is not suitable for clinicist's popularization and application.2, cell taking gun biopsy of pleura art: structure is simple, cheap, easy to operate, is only suitable for the biopsy of pleura of pachynsis and adherence of pleura.3, biopsy needle biopsy of pleura art (2 kinds dissimilar): 1. Abram Pleura biopsy needle; 2. Cope Pleura biopsy needle.At present, the application of Improvement type Cope Pleura biopsy needle is more clinically, although this biopsy needle structure is simple, cheap, pleura scope of selecting material limits to, and the piece of tissue of acquisition is less, and pleura positive rate is low, and operator's technical requirement is higher.
Applicant is disclose a kind of tong type pleural biopsy trocars in the utility model patent of 200820076324.3 in the patent No., comprise nook closing member, trocar sheath that turning set is loaded on nook closing member outer surface, the inner chamber of trocar sheath and the snakelike neck of wire type biopsy forceps rotate adaptation.Trocar sheath adopts straight tube or shaped form pipe, above-mentioned prior art also exist as trocar sheath adopts straight tube then can biopsy diaphram or visceral pleura, as trocar sheath adopts shaped form Guan Zeke biopsy diaphram pleura, but be difficult to biopsy parietal pleura.One is the design of original nook closing member, causes the running resistance in trocar sheath large, turnover difficulty.Two is that parietal pleura biopsy difficulty is higher, and success rate is lower due to the restriction of shaped form pipe curvature.Three is that original needle design easily forms further damage to puncture.
Summary of the invention
It is large that the purpose of this utility model is to provide a kind of biopsy scope, and operation easier is low damages little C shape Pleura biopsy needle with puncture.
Overall technology structure of the present utility model is:
C shape Pleura biopsy needle, comprises nook closing member, trocar sheath that turning set is loaded on nook closing member outer surface, and the inner chamber of trocar sheath and the snakelike neck of wire type biopsy forceps rotate adaptation; Described trocar sheath is c-shaped, described nook closing member comprise connect successively from front to back be positioned at anterior needle point, shank and backshank, described shank adopts and the rigid with deflection degree adaptive with trocar sheath to make.
Concrete technical construction of the present utility model also has:
For realizing the location of trocar sheath, be beneficial to the carrying out of puncture and biopsy, preferred technical implementation way is, the end of described trocar sheath is the bulging structure that an outer wall is provided with positive stop lug boss or convex edge.
Painful for alleviating operation, be beneficial to sleeve pipe and enter chest, preferred technical implementation way is, the outer tube wall of the front end of described trocar sheath is a variable-diameter structure of shrinking to axle center.Wherein more preferably adopt the reducing contraction structure seamlessly transitted.
For avoiding the seepage of tissue fluid, preferred embodiment, described nook closing member end is connected with the bulging sealing cap with trocar sheath inner chamber end adaptation.
The making of shank preferably adopts the rigid with certain deflection degree to make, and its objective is that be convenient to nook closing member advances freely in C shape trocar sheath, comprising but be not limited to and adopt boundling steel wire or engineering plastics for making material.
For reducing needle point and the running resistance of shank in trocar sheath, being convenient to needle point and shank enters smooth and easy trocar sheath expert, being convenient to be formed with outer sleeve inner wall outside needle point seal simultaneously.Preferred technical scheme is, described needle point entirety is in spindle, and its front end is Rhizoma Sparganii taper and rear portion is a varying diameter portion of inwardly shrinking, and this varying diameter portion is connected with shank, can it is evident that this connecting portion preferably adopts and seamlessly transit.
Operation principle of the present utility model is:
After determining the position of biopsy of pleura, sterilize, anaesthetize, try on, cut skin at point of puncture sharp knife sheet and deeply reach holostrome, width is about isometric with trocar sheath external diameter, with holding tight trocar sheath handle, the tip alignment otch that trocar front end is exposed, is steadily firmly sent into thoracic cavity, extract the nook closing member of the trocar, wire type biopsy forceps is sent into thoracic cavity along trocar sheath inner chamber.Slidably reciprocate biopsy forceps in pushed forward trocar process, its front resistance is detected with binding clip (binding clip opened or closed), finally biopsy forceps is sent in thoracic cavity, according to presetting inserting needle route and biopsy site, or at CT, x-ray, ultrasound guidance, implementing stinging of different parts pleura and getting, after Pleura biopsy needle sends into thoracic cavity, rotate Pleura biopsy needle tail end, its front end can be moved towards parietal pleura on a large scale, expands parietal pleura biopsy scope.After biopsy completes, extract biopsy needle and trocar sheath, pressure dressing wound.
Technological progress acquired by this utility model is:
1, trocar sheath and nook closing member adopt adaptive C shape structure, and its front end can be moved towards parietal pleura on a large scale, expands parietal pleura biopsy scope.
2, shank adopts the rigid with certain deflection degree to make, soft and high resilience, increases C shape trocar sheath curvature and nook closing member in the compliance of C shape overcoat in-pipe, makes different parts thoracic cavity parietal layer biopsy of pleura become possibility.
3, needle point is spindle and its front end is the structural design of Rhizoma Sparganii taper, makes needle point short and small, strong, sharp, and needle point and shank enter smooth and easy and resistance is little trocar sheath expert.
